Abstract
ABSTRACT Therapeutic vaccination has long been a promising avenue for cancer immunotherapy but is often limited by tumor heterogeneity. The genetic and molecular diversity between patients often results in variation in the antigens present on cancer cell surfaces. As a result, recent research has focused on personalized cancer vaccines. Although promising, this strategy suffers from time-consuming production, high cost, inaccessibility, and targeting of a limited number of tumor antigens. Instead, we explore an antigen-agnostic polymeric in situ cancer vaccination platform for treating blood malignancies, in our model here with acute myeloid leukemia (AML). Rather than immunizing against specific antigens or targeting adjuvant to specific cell-surface markers, this platform leverages a characteristic metabolic and enzymatic dysregulation in cancer cells that produces an excess of free cysteine thiols on their surfaces. These thiols increase in abundance after treatment with cytotoxic agents such as cytarabine, the current standard of care in AML. The resulting free thiols can undergo efficient disulfide exchange with pyridyl disulfide (PDS) moieties on our construct and allow for in situ covalent attachment to cancer cell surfaces and debris. PDS-functionalized monomers are incorporated into a statistical copolymer with pendant mannose groups and TLR7 agonists to target covalently linked antigen and adjuvant to antigen-presenting cells in the liver and spleen after IV administration. There, the compound initiates an anticancer immune response, including T-cell activation and antibody generation, ultimately prolonging survival in cancer-bearing mice.

Abstract
Nanoscale materials have demonstrated a very high potential in anticancer therapy by properly adjusting their functionalization and physicochemical properties. Herein, we report the synthesis of some novel vanadocene-loaded silica-based nanomaterials incorporating four different S-containing amino acids (penicillamine, methionine, captopril, and cysteine) and different fluorophores (rhodamine B, coumarin 343 or Alexa Fluor™ 647), which have been characterized by diverse solid-state spectroscopic techniques viz; FTIR, diffuse reflectance spectroscopies,13C and51V solid-state NMR spectroscopy, thermogravimetry and TEM. The analysis of the biological activity of the novel vanadocene-based nanostructured silicas showed that the materials containing cysteine and captopril aminoacids demonstrated high cytotoxicity and selectivity against triple negative breast cancer cells, making them very promising antineoplastic drug candidates. According to the biological results it seems that vanadium activity is connected to its incorporation through the amino acid, resulting in synergy that increases the cytotoxic activity against cancer cells of the studied materials presumably by increasing cell internalization. The results presented herein hold significant potential for future developments in mesoporous silica-supported metallodrugs, which exhibit strong cytotoxicity while maintaining low metal loading. They also show potential for theranostic applications highlighted by the analysis of the optical properties of the studied systems after incorporating rhodamine B, coumarin 343 (possible)in vitroanticancer analysis, or Alexa Fluor™ 647 (in vivostudies of cancer models).

Abstract
INTRODUCTION In recent years, highly selective reversible CDK4/6 inhibitors have been combined with aromatase inhibitors for their efficacy and ease of application in the treatment of advanced stage of hormone-responsive breast cancers. Oral use of these drugs facilitates patient compliance. However, adverse drug reactions are reported due to these drugs, in the literature. Diverse adverse reactions such as skin reactions, liver toxicity, and vitiligo with ribociclib have been reported. CASE REPORT In this study, we present of liver toxicity due to the use of ribociclib in a case of advanced breast cancer with metastases. It is noteworthy that the patient did not have any other concomitant disease and did not take any other medication. MANAGEMENT AND OUTCOME After the 600 mg initial dose of ribociclib, neutropenia occurred at the beginning of the therapy, the dose was reduced to 400 mg, and liver enzymes started to rise in the second month of the therapy. In the fifth month of the intermittent treatment period, liver toxicity was grade 3. DISCUSSION Liver adverse reaction occurred due to ribociclib use in the patient who had no history of any other disease. The Naranjo algorithm score was evaluated as 9. Considering the excretion of ribociclib by sulfation, cysteine conjugation, and glucuronidation, which are phase II reactions, n-acetyl cysteine (NAC) treatment (600 mg/day) was started for the patient. NAC therapy is recommended to reduce elevated liver enzymes in the case. The patient's treatment has been continuing with palbociclib for 5 months. No increase in liver enzymes was observed.

Abstract
BACKGROUND Emerging literature has suggested the antiepileptic activity of cysteine leukotriene receptor (CysLTR) antagonists in experimental animals of epilepsy. Leukotrienes are substances that cause inflammation and affect brain activity, blood flow, oxidation, and inflammation in the brain. These processes are related to epilepsy and its complications. CysLTR antagonists are drugs that prevent leukotrienes from working. They may be useful for treating epilepsy, especially for people who do not respond to other drugs. Therefore, the current study aims to systematically review the potential anti-seizure effect of CysLTR antagonists in experimental studies. METHOD We systematically reviewed the online databases using online databases such as Google Scholar, science direct, and PubMed until December 2022 to identify experimental studies assessing the anti-seizure activity of CysLTR antagonists. The Systematic Review Centre for Laboratory Animal Experimentation (SYRCLE) was used to evaluate the risk of bias (RoB) of the included studies. RESULTS Initially we identified 3823 studies. After screening using inclusion and exclusion criteria, 8 studies were finally included in the current study. All included studies, reported that CysLTR antagonists reduced the intensity of seizures in animal models of epilepsy. CONCLUSION In conclusion, CysLTR antagonists could be a potential therapeutic approach for the treatment of epilepsy. However, further preclinical and clinical studies are required to confirm their efficacy, safety, and mechanism of anti-seizure activity.

Abstract
Retinal ischemia plays a vital role in vision-threatening retinal ischemic disorders, such as diabetic retinopathy, age-related macular degeneration, glaucoma, etc. The aim of this study was to investigate the effects of S-allyl L-cysteine (SAC) and its associated therapeutic mechanism. Oxidative stress was induced by administration of 500 μM H2O2 for 24 h; SAC demonstrated a dose-dependent neuroprotective effect with significant cell viability effects at 100 μM, and it concurrently downregulated angiogenesis factor PKM2 and inflammatory biomarker MCP-1. In a Wistar rat model of high intraocular pressure (HIOP)-induced retinal ischemia and reperfusion (I/R), post-administration of 100 μM SAC counteracted the ischemic-associated reduction of ERG b-wave amplitude and fluorogold-labeled RGC reduction. This study supports that SAC could protect against retinal ischemia through its anti-oxidative, anti-angiogenic, anti-inflammatory, and neuroprotective properties.

Abstract
Hydrogen sulfide (H2S) is a gasotransmitter implied in metabolic diseases, insulin resistance, obesity, and type 2 Diabetes Mellitus. This study aimed to determine the effect of chronic administration of sodium hydrosulfide (NaHS; inorganic H2S donor), L-Cysteine (L-Cys; substrate of H2S producing enzymes) and DL-Propargylglycine (DL-PAG; cystathionine-gamma-lyase inhibitor) on the vascular dysfunction induced by insulin resistance in rat thoracic aorta. For this purpose, 72 animals were divided into two main sets that received: 1) tap water (control group; n = 12); and 2) fructose 15% w/v in drinking water [insulin resistance group (IR); n = 60] for 20 weeks. After 16 weeks, the group 2 was divided into five subgroups (n = 12 each), which received daily i. p. injections during 4 weeks of: 1) non-treatment (control); 2) vehicle (phosphate buffer saline; PBS, 1 ml/kg); 3) NaHS (5.6 mg/kg); 4) L-Cys (300 mg/kg); and (5) DL-PAG (10 mg/kg). Hemodynamic variables, metabolic variables, vascular function, ROS levels and the expression of p-eNOS and eNOS were determined. IR induced: 1) hyperinsulinemia; 2) increased HOMA-index; 3) decreased Matsuda index; 4) hypertension, vascular dysfunction, increased ROS levels; 5) increased iNOS, and 6) decreased CSE, p-eNOS and eNOS expression. Furthermore, IR did not affect contractile responses to norepinephrine. Interestingly, NaHS and L-Cys treatment, reversed IR-induced impairments and DL-PAG treatment decreased and increased the HOMA and Matsuda index, respectively. Taken together, these results suggest that NaHS and L-Cys decrease the metabolic and vascular alterations induced by insulin resistance by reducing oxidative stress and activating eNOS. Thus, hydrogen sulfide may have a therapeutic application.

Abstract
BACKGROUND Iruplinalkib is a novel anaplastic lymphoma kinase (ALK) inhibitor for the treatment of ALK-positive crizotinib-resistant NSCLC. RESEARCH DESIGN AND METHODS A single oral dose of 120 mg/3.7 MBq [14C]iruplinalkib was administered to healthy subjects. Blood, urine and fecal samples were collected and analyzed for iruplinalkib and its metabolites. The safety of iruplinalkib was also assessed. RESULTS Iruplinalkib was absorbed quickly and eliminated slowly from plasma, with a Tmax of 1.5 h and t1/2 of 28.6 h. About 88.85% of iruplinalkib was excreted at 312 h, including 20.23% in urine and 68.63% in feces. Seventeen metabolites of iruplinalkib were identified, and M3b (demethylation), M7 (cysteine conjugation), M11 (oxidative dehydrogenation and cysteine conjugation of M3b) and M12 (oxidative dehydrogenation and cysteine conjugation) were considered the prominent metabolites in humans. Iruplinalkib-related compounds were found to be covalently bound to proteins, accounting for 7.70% in plasma and 17.96% in feces, which suggested chemically reactive metabolites were formed. There were no serious adverse events observed in the study. CONCLUSIONS Iruplinalkib was widely metabolized and excreted mainly through feces in humans. Unchanged iruplinalkib, cysteine conjugates and covalent protein binding products were the main drug-related compounds in circulation. Iruplinalkib was well tolerated at the study dose. TRIAL REGISTRATION The trial is registered at ClinicalTrials.gov (Identifier: Anonymized).

Abstract
BACKGROUND/IMPORTANCE Dietary interventions, vitamins, and nutritional supplementation are playing an increasingly important role in the management of neuropathic pain. Current pharmacological treatments are poorly tolerated and ineffective in many cases. OBJECTIVE This systematic review aims to study the efficacy of dietary interventions, vitamins, and nutritional supplementation in the management of chronic neuropathic pain in adults. EVIDENCE REVIEW The review followed PRISMA guidelines and was registered with PROSPERO (#CRD42022300312). Ten databases and gray literature, including Embase.com, MEDLINE and Web of Science, were systematically searched using a combination of keywords and controlled vocabulary related to chronic neuropathic pain and oral non-pharmacological supplements. Studies on adult humans published between 2000 and 2021 were considered for inclusion. The Cochrane Handbook was used to assess risk of bias, and Grading of Recommendations Assessment, Development, and Evaluation was used to determine overall quality of evidence. FINDINGS Forty studies were included in the final review, and results were categorized according to pain type including pain related to chemotherapy-induced peripheral neuropathy (CIPN, 22 studies, including 3 prospective cohorts), diabetic peripheral neuropathy (DPN, 13 studies, including 2 prospective), complex regional pain syndrome (CRPS-I, 3 studies, including 1 prospective), and other (2 studies, both RCT). The CIPN studies used various interventions including goshajinkigan (4 studies), vitamin E (5), vitamin B12 (3), glutamine (3), N-acetyl-cysteine (2), acetyl-l-carnitine (2), guilongtonluofang (1), ninjin'yoeito (1), alpha-lipoic acid (1), l-carnosine (1), magnesium and calcium (1), crocin (1), and antioxidants (1), with some studies involving multiple interventions. All CIPN studies involved varying cancers and/or chemotherapies, advising caution for generalizability of results. Interventions for DPN included alpha-lipoic acid (5 studies), vitamin B12 (3), acetyl-l-carnitine (3), vitamin E (1), vitamin D (2), and a low-fat plant-based diet (1). Vitamin C was studied to treat CRPS-I (3 studies, including 1 prospective). Magnesium (1) and St. John's wort (1) were studied for other or mixed neuropathologies. CONCLUSIONS Based on the review, we cannot recommend any supplement use for the management of CIPN, although further research into N-acetyl-cysteine, l-carnosine, crocin, and magnesium is warranted. Acetyl-l-carnitine was found to be likely ineffective or harmful. Alpha-lipoic acid was not found effective. Studies with goshajinkigan, vitamin B12, vitamin E, and glutamine had conflicting results regarding efficacy, with one goshajinkigan study finding it harmful. Guilongtonluofang, ninjin'yoeito, and antioxidants showed various degrees of potential effectiveness. Regarding DPN, our review supports the use of alpha-lipoic acid, acetyl-l-carnitine, and vitamin D. The early use of vitamin C prophylaxis for the development of CRPS-I also seems promising. Further research is warranted to confirm these findings.

Abstract
Photodynamic therapy (PDT) has been used to reduce cancerous and precancerous cells via reactive oxygen species (ROS) generation from photosensitizers. Numerous photosensitizers are available today to treat a variety of diseases, but their therapeutic efficacy is hindered within the tumor microenvironment, and there are safety concerns associated with their non-specific activation. In this work, we disclosed a nano-therapeutic based on in situ activatable nitrobenzene-cysteine-copper(II) nano-complexes (NCCNs) that work within cancer cells. Among the NCCNs, CyP shows outstanding potential as a promising candidate for programmed photodynamic cancer therapy with its unique properties such as (i) bright near-infrared imaging, (ii) chemodynamic therapeutic effect, (iii) photodynamic therapeutic effect (types I and II), and (iv) anti-cancer effect by anti-angiogenesis in early cancer stage under light. Overall, this work opens up exciting possibilities for the development of innovative and effective treatments for cancer, paving the way for future advancements in the clinical medicine field.

Abstract
The purpose of this study was to investigate the effect of aqueous extract of Corni Fructus on β-amyloid protein 25-35(Aβ_(25-35))-induced brain injury and neuroinflammation in Alzheimer's disease(AD) mice to provide an experimental basis for the treatment of AD by aqueous extract of Corni Fructus. Sixty C57BL/6J male mice were randomly divided into a sham group, a model group, a positive control group(huperizine A, 0.2 mg·kg~(-1)), a low-dose aqueous extract of Corni Fructus group(1.3 g·kg~(-1)), a medium-dose aqueous extract of Corni Fructus group(2.6 g·kg~(-1)), and a high-dose aqueous extract of Corni Fructus group(5.2 g·kg~(-1)). The AD model was induced by lateral ventricular injection of Aβ_(25-35) in mice except for those in the sham group, and AD model mice were treated with corresponding drugs by gavage for 24 days. The behavioral test was performed one week before animal dissection. Hematoxylin-eosin(HE) staining was performed to observe the morphology of neurons in the hippocampal region. Flow cytometry was used to detect the apoptosis level of primary hippocampal cells in mice. ELISA kits were used to detect the levels of β-amyloid protein 1-42(Aβ_(1-42)) and phosphorylated microtubule-associated protein Tau(p-Tau) in mouse brain tissues. Immunofluorescence and Western blot were used to detect the expression of related proteins in mouse brain tissues. MTT assay was used to detect the effect of compounds in aqueous extract of Corni Fructus on Aβ_(25-35)-induced N9 cell injury. Molecular docking was employed to analyze the interactions of caffeic acid, trans-p-hydroxy cinnamic acid, isolariciresinol-9'-O-β-D-glucopyranoside, esculetin, and(+)-lyoniresinol with β-amyloid precursor protein(APP), interleukin-6(IL-6), and tumor necrosis factor-α(TNF-α). Aqueous extract of Corni Fructus could improve the learning and memory abilities of Aβ_(25-35)-induced mice by increasing the duration of the autonomous activity, the rate of autonomous alternation, the preference coefficient, and the discrimination coefficient, and reduce Aβ_(25-35)-induced brain injury and neuroinflammation in mice by increasing the expression levels of interleukin-10(IL-10) and B-cell lymphoma-2(Bcl-2) in brain tissues, decreasing the expression levels of Aβ_(1-42), p-Tau, IL-6, TNF-α, cysteine aspartate-specific protease 3(caspase-3), cysteine aspartate-specific protease 9(caspase-9), and Bcl-2-associated X protein(Bax), and decreasing the number of activated glial cells in brain tissues. The results of cell experiments showed that esculetin and(+)-lyoniresinol could improve Aβ_(25-35)-induced N9 cell injury. Molecular docking results showed that caffeic acid, trans-p-hydroxy cinnamic acid, isolariciresinol-9'-O-β-D-glucopyranoside, esculetin, and(+)-lyoniresinol had good binding affinity with APP and weak binding affinity with IL-6 and TNF-α. Aqueous extract of Corni Fructus could ameliorate cognitive dysfunction and brain damage in Aβ_(25-35)-induced mice by reducing the number of apoptotic cells and activated glial cells in the brain and decreasing the expression level of inflammatory factors. Caffeic acid, trans-p-hydroxy cinnamic acid, isolariciresinol-9'-O-β-D-glucopyranoside, esculetin, and(+)-lyoniresinol may be the material basis for the anti-AD effect of aqueous extract of Corni Fructus.

Abstract
BACKGROUND Available experimental and clinical evidence indicates that N-Acetyl cysteine (NAC) may have an analgesic role in specific pain conditions, particularly neuropathic pain. Thus, we hypothesized that NAC supplementation might be also helpful in decreasing pain and improving pain-related disability in patients with acute radiculopathy. We designed this study to investigate the potential use of NAC-adjunctive treatment to Nonsteroidal Anti- Inflammatory Drugs (NSAIDs) in patients with acute radiculopathy secondary to lumbar intervertebral disc herniation. METHODS Sixty-two patients diagnosed with acute lumbar radiculopathy associated with disc herniation were randomly allocated to the NAC or the placebo groups. Besides naproxen at a dose of 500 mg twice a day, participants based on their allocation group started with NAC or matched placebo at a dose of 600 mg twice a day for eight weeks. The pain severity, measured by the Visual Analog Scale (VAS), and pain-related disability measured by the Oswestry Disability Index (ODI) were measured at baseline and weeks 2, 4, and 8 of treatment. Global improvement of symptoms rated by Patient and Clinical Global Impressions of Change (PGIC and CGIC) was also recorded at the end of week 8. All analyses were conducted on an Intentionto- Treat (ITT) analysis data set. RESULTS A comparison of the VAS and ODI scores at weeks 2 and 4 of the treatment between the two groups did not show a significant difference. In contrast, from week 4 to week 8, we noticed a significantly greater reduction in the mean VAS and ODI scores in the NAC group compared to the placebo group (p-value <0.001 for both variables). In parallel with these results, also, more NAC-treated than placebo-treated patients achieved treatment success defined as ''very much'' or ''much improved'' on CGIC and PGIC scales, and these differences reached a significant level (p-value = .011 and p-value = .043). CONCLUSIONS This study suggested that NAC might be a relevant candidate for adjunct therapy in managing acute lumbar radiculopathy. Additional clinical trials are needed to validate these findings.

Abstract
BACKGROUND Diarrhea-predominant irritable bowel syndrome (IBS-D) is a common functional gastrointestinal disease. Tong-Xie-Yao-Fang (TXYF), the traditional Chinese herbal medicine prescription, is a classic and effective prescription for the treatment of IBS-D, but its mechanism of action is not fully clarified. OBJECTIVE To evaluate the efficacy of TXYF in the treatment of IBS-D and to explore its potential mechanism of action. METHODS Changes in the serum levels of 50 free amino acids were targeted for detection by high-performance liquid chromatography (HPLC), and the expression of glucose-regulated protein 78 (GRP78), general control nonderepressible 2 (GCN2), and endoplasmic reticulum-resident kinase (PERK) was detected by immunohistochemistry examinations in healthy volunteers and IBS-D patients. The IBS-D rat was constructed by the three-factor superposition method of neonatal maternal separation, 2,4,6-trinitrobenzene sulfonic acid enema, and chronic unpredictable stress stimulation. The treatment effect of TXYF on IBS-D rats was observed by recording the body weight, grasp force, fecal water content (FWC), and abdominal withdrawal reflex (AWR) of rats before and after treatment. The effects of GCN2/PERK-eukaryotic initiation factor-2 (eIF2α) -activating transcription Factor 4 (ATF4) pathway proteins and gene expression were analyzed by western blotting, reverse transcription-polymerase chain reaction (RT-qPCR), and immunohistochemistry evaluations. RESULTS Compared with healthy volunteers, IBS-D patients exhibited lower levels of cysteine, γ-aminoacetic acid (GABA), homoproline, and lysine, and immunohistochemistry showed strong activation of GRP78, a marker of endoplasmic reticulum stress. Differential expression of GCN2 and PERK proteins was detected in IBS-D patients and rat colons. In the IBS-D rats, TXYF improved the body weight and grasp force, reduced the FWC, and improved the AWR score. TXYF increased the levels of p-GCN2 and GCN2 and reduced the levels of GRP78, p-PERK, PERK, p-eIF2α, and eIF2α, thereby affecting the expression of the apoptosis-related transcription factors ATF4, CHOP, Caspase-3, and Bcl-2. CONCLUSION Our study showed that TXYF improved IBS-D by inhibiting apoptosis. The anti-apoptosis effects were potentially mediated by regulating the GCN2/PERK-eIF2a-ATF4 signaling pathway.

Abstract
Treatment of Ischemic Stroke is inordinately challenging due to its complex aetiology and constraints in shuttling therapeutics across blood-brain barrier. Ropinirole hydrochloride (Rp), a propitious neuroprotectant with anti-oxidant, anti-inflammatory, and anti-apoptotic properties (3A) is repurposed for remedying ischemic stroke and reperfusion (I/R) injury. The drug's low bioavailability in brain however, limits its therapeutic efficacy. The current research work has reported sub-100 nm gamma-L-Glutamyl-L-Cysteine coated Human Serum Albumin nanoparticles encapsulating Rp (C-Rp-NPs) for active targeting in ischemic brain to encourage in situ activity and reduce unwanted toxicities. Confocal microscopy and brain distribution studies confirmed the enhanced targeting potentiality of optimized C-Rp-NPs. The pharmacokinetics elucidated that C-Rp-NPs could extend Rp retention in systemic circulation and escalate bioavailability compared with free Rp solution (Rp-S). Additionally, therapeutic assessment in transient middle cerebral occlusion (tMCAO) model suggested that C-Rp-NPs attenuated the progression of I/R injury with boosted therapeutic index at 1000 times less concentration compared to Rp-S via reinstating neurological and behavioral deficits, while reducing ischemic neuronal damage. Moreover, C-Rp-NPs blocked mitochondrial permeability transition pore (mtPTP), disrupted apoptotic mechanisms, curbed oxidative stress and neuroinflammation, and elevated dopamine levels post tMCAO. Thus, our work throws light on fabrication of rationally designed C-Rp-NPs with enormous clinical potential.

Abstract
New therapies are needed to improve the low survival rates of patients with metastatic colon cancer. Evidence suggests that amino acid (AA) restriction can be used to target the altered metabolism of cancer cells. In this work, we evaluated the therapeutic potential of selective AA restriction in colon cancer. After observing anticancer activity in vitro, we prepared several artificial diets and evaluated their anticancer activity in two challenging animal models of metastatic colon cancer. These models were established by injecting CT26.WT murine colon cancer cells in the peritoneum (peritoneal dissemination) or in the tail vein (pulmonary metastases) of immunocompetent BALB/cAnNRj mice. Capecitabine, which is a first-line treatment for patients with metastatic colon cancer, was also evaluated in these models. Mice fed diet TC1 (a diet lacking 10 AAs) and diet TC5 (a diet with 6% casein, 5% glutamine, and 2.5% leucine) lived longer than untreated mice in both models; several mice survived the treatment. Diet TC5 was better than several cycles of capecitabine in both cancer models. Cysteine supplementation blocked the activity of diets TC1 and TC5, but cysteine restriction was not sufficient for activity. Our results indicated that artificial diets based on selective AA restriction have therapeutic potential for colon cancer.

Abstract
Aberrant expression of MYC transcription factor family members predicts poor clinical outcome in many human cancers. Oncogenic MYC profoundly alters metabolism and mediates an antioxidant response to maintain redox balance. Here we show that MYCN induces massive lipid peroxidation on depletion of cysteine, the rate-limiting amino acid for glutathione (GSH) biosynthesis, and sensitizes cells to ferroptosis, an oxidative, non-apoptotic and iron-dependent type of cell death. The high cysteine demand of MYCN-amplified childhood neuroblastoma is met by uptake and transsulfuration. When uptake is limited, cysteine usage for protein synthesis is maintained at the expense of GSH triggering ferroptosis and potentially contributing to spontaneous tumor regression in low-risk neuroblastomas. Pharmacological inhibition of both cystine uptake and transsulfuration combined with GPX4 inactivation resulted in tumor remission in an orthotopic MYCN-amplified neuroblastoma model. These findings provide a proof of concept of combining multiple ferroptosis targets as a promising therapeutic strategy for aggressive MYCN-amplified tumors.

Abstract
Repeated manganese (Mn) exposure may cause increased production of reactive oxygen species (ROS), with a consequent imbalance in the glutathione (GSH) antioxidant defence system, resulting in cellular dysfunctions, and eventually cell death, particularly in the brain. D-ribose-L-cysteine (RibCys) has been demonstrated to effectively promote the synthesis of glutathione, a potent neutralizer of ROS. In the present study, we examined the effects of RibCys on glutathione levels, apoptotic and astrocytic responses, neuronal ultrastructural integrity, following Mn exposure. Wild-type rats were exposed to either saline, Mn, or/and RibCys for 2 weeks. The Mn-exposed rats received RibCys either as pre-, co-, or post-treatments. Mn caused a marked decrease in GSH levels, overexpression of GFAP and caspase-3, reflecting astrocytosis and apoptosis, and altered ultrastructural integrities of the neuronal nuclei, mitochondria, and myelin sheath of the striatum and motor cortex respectively, while all interventions with RibCys minimized and prevented the neurotoxic events. Our study demonstrates that RibCys effectively attenuates the neurotoxic effects of Mn and may be useful as a therapeutic strategy against neurological consequences of Mn overexposure.

Abstract
Health-related quality of life (HRQoL) is an important consideration in managing patients. Spleen aminopeptide oral lyophilized powder (SAOLP) has been used to enhance cellular immunity in a patient. This multicenter, randomized, double-blind, placebo-controlled clinical trial was designed to evaluate the safety and efficacy of SAOLP for improving HRQoL in patients with breast cancer. Patients diagnosed with advanced breast cancer were included, and were administered SAOLP or placebo 4 mg qd for two cycles. The primary endpoint was improvement in HRQoL on day 42 measured by the EORTC QLQ-C30 and EORTC QLQ-BR23. Secondary endpoints included immunologic function, improvement in HRQoL on day 21 and 84, objective response rate, disease control rate, BMI and adverse events. On day 42, on the EORTC QLQ-C30 or EORTC QLQ-BR23, scores on the functional scales and QoL scale were significantly higher and scores on symptom scales were significantly lower in patients who received SAOLP compared to placebo (P < 0.05). On day 84, the number of CD3, CD4 and CD8 cells were significantly higher in patients who received SAOLP. There were no significant differences in objective response rate, disease control rate or BMI. SAOLP may improve HRQoL and the immune response in patients with advanced breast cancer, represents a convenient and safe adjuvant therapy.

Abstract
Pulmonary hypertension (PH) is a progressive and life-threatening chronic disease in which increased pulmonary artery pressure (PAP) and pulmonary vasculature remodeling are prevalent. Inhaled nitric oxide (NO) has been used in newborns to decrease PAP in the clinic; however, the effects of NO endogenous derivatives, S-nitrosothiols (SNO), on PH are still unknown. We have reported that S-nitroso-L-cysteine (CSNO), one of the endogenous derivatives of NO, inhibited RhoA activity through oxidative nitrosation of its C16/20 residues, which may be beneficial for both vasodilation and remodeling. In this study, we presented data to show that inhaled CSNO attenuated PAP in the monocrotaline- (MCT-) induced PH rats and, moreover, improved right ventricular (RV) hypertrophy and fibrosis induced by RV overloaded pressure. In addition, aerosolized CSNO significantly inhibited the hyperactivation of signal transducers and activators of transduction 3 (STAT3) and extracellular regulated protein kinases (ERK) pathways in the lung of MCT-induced rats. CSNO also regulated the expression of smooth muscle contractile protein and improved aberrant endoplasmic reticulum (ER) stress and mitophagy in lung tissues following MCT induction. On the other hand, CSNO inhibited reactive oxygen species (ROS) production in vitro, which is induced by angiotensin II (AngII) as well as interleukin 6 (IL-6). In addition, CSNO inhibited excessive ER stress and mitophagy induced by AngII and IL-6 in vitro; finally, STAT3 and ERK phosphorylation was inhibited by CSNO in a concentration-dependent manner. Taken together, CSNO led to pulmonary artery relaxation and regulated pulmonary circulation remodeling through anti-ROS and anti-inflammatory pathways and may be used as a therapeutic option for PH treatment.

Abstract
Vitamin D (VD) deficiency is associated with musculoskeletal disorders. This study examines whether co-supplementation of l-cysteine (LC) and VD is better than monotherapy with LC or VD at alleviating musculoskeletal dyshomeostasis in the skeletal muscle of VD-deficient high-fat diet (HFD-VD-) fed mice. Mice were fed a healthy diet or an HFD; for VD-deficient animals, the mice were maintained on a HFD-VD-diet (16 weeks); after the first 8 weeks, the HFD-VD-diet-fed mice were supplemented for another 8 weeks with LC, VD-alone, or the same doses of LC + VD by oral gavage. Saline and olive oil served as controls. Myotubes were exposed with high-glucose, palmitate, Monocyte Chemoattractant Protein 1 (MCP-1), and Tumor Necrosis Factor (TNF), to mimic the in vivo microenvironment. In vitro deficiencies of glutathione and hydrogen sulfide were induced by knockdown of GCLC and CSE genes. Relative gene expression of biomarkers (myogenic: MyoD, Mef2c, Csrp3; muscle dystrophy: Atrogin1, Murf1, and Myostatin; bone modeling and remodeling: RANK, RANKL, OPG) were analyzed using qRT-PCR. Co-supplementatoin with LC + VD showed beneficial effects on gene expression of myogenic markers and OPG but reduced markers of dystrophy, RANK/RANKL in comparison to LC or VD alone-supplementation. In vitro myotubes treated with glutathione (GSH) precursors also showed a positive effect on OPG and the myogenesis genes, and inhibited RANK/RANKL and muscle-dystrophy markers. This study reveals that the co-supplementation of LC with VD significantly alleviates the markers of musculoskeletal disorders in the skeletal muscle better than monotherapy with LC or VD in HFD-VD-fed mice.

Abstract
In experimental rabbits, cysteine injected intravenously in a dose of 1000 mg/kg temporarily bound zinc in β cells and prevented the formation of chelate zinc complexes in response to subsequent injection of diabetogenic zinc-binding substances that induce cell destruction. Injection of cysteine to animals was associated with a sharply negative reaction to zinc in β cells, which attests to blockade of zinc ions. Injection of cysteine few minutes after dithizone and formation of zinc-dithizone complex was followed by displacement of dithizone from the complex and prevented the development of diabetes in most animals. The most plausible mechanism of preventive effect of cysteine is the formation of 2:1 zinc-cysteine complex in β cells with possible fixation of Zn atom between sulfur atoms from SH groups of two cysteine molecules.

Abstract
An 81-year-old woman with rheumatoid arthritis (RA) who had been treated with bucillamine presented with dyspnea. Computed tomography of the chest showed ground-glass opacities and consolidations in both lungs and honeycombing in both basal lung areas. An elevation of the serum Krebs von den Lungen-6 level and hypoxemia were seen. Lymphocytosis with a decreased CD4/CD8 ratio was seen in the bronchoalveolar lavage fluid. A transbronchial lung biopsy specimen showed organizing pneumonia. Based on a diagnosis of bucillamine-induced pneumonitis (BIP) with RA-associated pre-existing interstitial pneumonia, she was successfully treated with the cessation of bucillamine and systemic corticosteroid therapy. The risk factors and prognosis of BIP are discussed.

Abstract
Bioactive components of dietary phytochemicals have been reported to possess antitumor activities. Evidences suggested key role of stress responsive p38MAPK in the induction of nutraceuticals mediated apoptosis in hepatocellular carcinoma (HCC). Current study demonstrated detailed molecular bagatelle associated with p38 MAPK mediated effective suppression of cell growth both in HepG2 and chemically induced liver carcinoma after S-allyl cysteine (SAC) treatment. SAC promoted p38MAPK activity responsible for p53 phosphorylation, its stabilization followed by nuclear translocation leading to induction in expression and oligomerization of Fas protein. Distinctive p38MAPK-p53 axis dependent Fas-FasL-FADD mediated caspase activities along with perturbed cell cycling became normalized with continuation of SAC treatment for another month to diethylnitrosamine induced liver carcinoma. Co-treatment with SB203580, the p38MAPK inhibitor, prevented pro-apoptotic effect of SAC by altering p53 phosphorylation and death inducing signaling complex conformation in HepG2 and induced HCC. Collectively study suggested significant contribution of p38MAPK-p53-DISC-Caspase pathway in the regulation of anti-neoplastic activity of SAC against HCC.

Abstract
The purpose of this study was to conduct a comparative analysis of the effectiveness of isolated and combined use of intradermal injections of bioreparant (hyaluronic acid modified with vitamin C, glutathione and cysteine) and platelet-rich autologous plasma on functional indicators of the face skin of women with signs of 3-rd degree of photoaging. In this study, 120 women with 3-rd degree of photoaging were examined (mean age 34.5±1.54) and divided into 3 groups in accordance with the applied therapy method (isolated and combined use of plasma therapy and bio reparation). The study of the functional parameters of the skin, including corneometry (determination of the degree of epidermal hydration), sebometry (assessment of the sebum regulating function of the epidermis), cutometry (determination of the deformation and elastic properties of the skin), TEWL (determination of the transepidermal water loss level), mexametry (assessment of skin pigmentation) and pH-metry (assessment of the skin acid-base balance) was performed in all examined patients. The obtained results testify to various shifts in functional parameters, caused by the use of various therapeutic approaches. A comparative analysis of the data obtained has provided a basis for concluding that efficacy of the autologous plasma and modified hyaluronic acid combined implementation is significantly higher compared to the isolated application of these methods.

Abstract
BACKGROUND Garlic can be considered as a useful natural herb in inhibition of inflammation. The aim of this study was to assess the effectiveness of garlic extract in lowering inflammatory markers in peritoneal dialysis (PD) patients. METHODS In this parallel-designed double blind randomized clinical trial, 42 PD patients at the Shafa dialysis center, Tehran in 2017 were included. The primary outcome in this study was systemic inflammation which was evaluated by measuring the concentrations of IL-6 and CRP and ESR in serum. RESULTS Baseline versus after-intervention median (IQR) of IL-6 (pg/ml), CRP (mg/L) and mean ± SD of ESR (mm) in garlic and placebo groups was 2.2 (0.8, 6.4) versus 0.7 (0.6, 1.2) (p < 0.001) and 2.0 (0.8, 2.1) versus 0.6 (0.6, 0.8) (p = 0.002), 13.0 (5.0, 14.0) versus 2.0 (1.0, 9.0) (p < 0.001) and 7.0 (2.0, 10.0) versus 6.0 (3.7, 7.5) (p = 0.547) and 35.4 ± 21.7 versus 50.7 ± 28.5 (p = 0.021) and 46.0 ± 26.0 versus 45.3 ± 22.3 (p = 0.797). Median (IQR) of Percentage Before-After change in CRP was - 71.4%(- 85.7, - 42.9%) and - 20.0%(- 30.0, 114.3%) in garlic and placebo group respectively. The Mann-Whitney U test indicated this difference is statistically significant (p < 0.001). CONCLUSION The results imply that administrating 400 mg of standardized garlic extract twice a day for 8 weeks resulted in a significant reduction in IL-6, CRP and ESR. Since inflammatory state can be a serious life threatening condition in PD patients, we suggest prescribing this safe and well-tolerated natural substance to attenuate the inflammatory state in these patients. However, assessment of these effects in a larger randomized trial is strongly recommended (IRCTID: IRCT2017072535305N1, 2017-10-16).

Abstract
OBJECTIVE This study investigated effects of S-allylmercaptocysteine (SAMC), diallyl disulfide (DADS), and vitamin B12 on inner ear functions and morphology after long-period high-level broadband noise exposure. MATERIALS AND METHODS Twenty-four healthy rats were randomly divided into four groups. First group was chosen as the control group. Vitamin B12, SAMC, and DADS were applied to other groups for 4 weeks. On the 14th day, each group was exposed to broadband noise. Auditory brainstem response test was performed before and immediately after noise exposure and repeated on the 2nd and 14th day. RESULTS Permanent threshold shifts were significantly lower in groups treated with vitamin B12, SAMC, and DADS. Histologically, cochleae of SAMC and DADS groups were found to be better preserved than the cochleae of vitamin B12 and control groups. CONCLUSION Physiologically and histologically, SAMC and DADS reduced the long-term effects of noise. However, physiological recovery was not consistent with the morphological findings in vitamin B12 group.

Abstract
The article presents a theoretical generalization of the research results the effectiveness of heparisin on the state of the carbohydrate-protein components of the extracellular matrix of connective tissue in liver in patients with non-alcoholic steatohepatitis with obesity I-II degree and chronic kidney disease І-ІІ stage. The purpose of the study is to find out the effectiveness of heparisin (glycyrizine 40 mg, glycine 400 mg, L-cysteine hydrochloride 20 mg) on the state of the carbohydrate-protein components of the extracellular matrix in connective tissue of the liver in patients with non-alcoholic steatohepatitis (NASH) with obesity I-II degree and chronic kidney disease (CKD) І-ІІ stage. 98 patients with NASH on the background of obesity of the I-II degree were examined, including: 52 patients with NASH (I group) (without accompanying CKD), 46 patients with NASH with comorbid CKD І-ІІ stage (II group). The control group consisted of 20 practically healthy persons (PHPs) of the corresponding age and sex. Biopsy of the liver was performed on 32 NASH patients with CKD I-II, 28 patients with NASH without CKD. Patients on both groups of NASH received heparisin treatment (glycyrizine 40 mg, glycine 400 mg, L-cysteine hydrochloride 20 mg) (Valartin Pharma) by intravenous administration of 20 ml of the drug for 10 days followed by enteral administration of 2 tablets of heparysin (1 tablet : glycyrizine 25 mg, glycine - 25 mg, methionine - 25 mg) 3 times a day for 80 days. Patients with NASH and a comorbid flow of obesity and CKD of the І-ІІ stages, except for heparisin, received baseline therapy of CKD І-ІІ stage: chronic pyelonephritis. Heparizin therapy for 3 months contributed to the achievement of a collagen anabolic and catabolic balance by activating collagenase, inhibiting the activity of proteolytic inhibitors and collagenase, inhibition of fibroblast growth factor secretion, acute phase inflammation, reducing extracellular matrix fucoglycoproteinsdegradation in liver, and in general, reducing the activation of connective tissue components, by evidence which led to a decrease in the liver fibrosisindex according to the fibrotest in the range of 1.5-2.0 times.

Abstract
Yellow nail syndrome (YNS) pleurisy is often difficult to control, and pathological examinations have rarely been reported. We herein report a case of bucillamine-induced YNS in which histopathology of the parietal pleura revealed hyperplasia of the lymphoid follicles and lymphangiectasia. Even after the discontinuation of bucillamine, the pleurisy and lymphedema showed no change. Based on the histopathological findings showing similarity to rheumatoid pleurisy, we administered corticosteroid treatments, and both the pleurisy and lymphedema improved. The findings in the present case suggest that, in bucillamine-induced YNS, pleurisy may be related to inflammation caused by rheumatoid arthritis in addition to abnormalities in lymphatic vessels.

Abstract
Anemia of inflammation (AI) is clinically prevalent and greatly threatens public health. Traditional remedies have raised controversy during clinical practice, calling for alternative therapies. We have recently found that hydrogen sulfide (H2S) inhibits inflammatory hepcidin, the critical mediator of AI. However, due to the chemical property of H2S, there remains an urgent need for a stable H2S donor in AI treatment. Here we reported that S-propargyl-cysteine (SPRC), a novel water-soluble H2S donor, suppressed hepatic hepcidin and corrected hypoferremia induced by lipopolysaccharide. The effects of SPRC were reversed by inhibition of cystathionine γ-lyase, one of the major endogenous H2S synthases. Moreover, SPRC reduced serum hepcidin, improved transferrin saturation, and maintained erythrocyte membrane integrity in a chronic mouse AI model. Consistently, splenomegaly was ameliorated and splenic iron accumulation relieved. Mechanism study indicated that serum IL-6 content and hepatic Il-6 mRNA were decreased by SPRC, in parallel with reduced hepatic JAK2/STAT3 activation. On the whole, our data reveal the inhibition of inflammatory hepcidin by SPRC, and suggest SPRC as a potential remedy against AI.

Abstract
OBJECTIVES We evaluated the effects of S-allylcysteine (SAC) on biomarkers of the polyol pathway in streptozotocin-nicotinamide (STZ-NA)-induced diabetes in rats. METHODS Diabetes was induced in male albino Wistar rats by intraperitoneal administration of STZ (55 mg kg-1 bw-1) and NA (110 mg kg-1 bw-1). SAC (150 mg kg-1 bw-1) was orally administered to the rats with diabetes for 45 days to assess its effects on blood glucose, insulin, insulin resistance, glycated hemoglobin, aldose reductase (AR), sorbitol dehydrogenase (SDH), sorbitol, fructose, thiobarbituric acid-reactive substances (TBARS), hydroperoxide, hemoglobin and glutathione (GSH). RESULTS On SAC administration in the rats with diabetes, the levels of blood glucose, insulin resistance, glycated hemoglobin, AR, SDH, sorbitol, fructose, TBARS and hydroperoxide increased significantly (p<0.05), whereas those of insulin, hemoglobin and GSH decreased. SAC showed therapeutic effects similar to those of gliclazide in decreasing blood glucose, AR, SDH, sorbitol, fructose, glycosylated hemoglobin, TBARS and hydroperoxides levels and significant increases in insulin, hemoglobin and GSH activity in rats with diabetes. Moreover, histopathologic studies also revealed the protective effect of SAC on pancreatic beta cells. CONCLUSIONS The results indicate that SAC prevents complications of diabetes by reducing the influx of glucose in the polyol pathway, thereby elevating the GSH level and reducing the activities of AR and SDH. Therefore, SAC may have imperative implications for the deterrence and early treatment of type 2 diabetes.

Abstract
Conventional synthetic disease modifying anti-rheumatic drugs (csDMARDs) other than methotrexate (MTX: anchor csDMARDs) are effective for single use, reinforcement of MTX, biologics and induction and maintenance of biologics-free condition. Newly developed iguratimod (IGU) does not suppress immunological reaction, therefore, it is useful for single use or combination with other csDMARDs in patients with complications. IGU can be used as a first csDMARDs before MTX use during the screening for MTX. IGU might be effective for reinforcement of MTX, biologics and induction and maintenance of biologics-free condition just like other csDMARDs. IGU can be used in wide variety of situation of the treatment of rheumatoid arthritis and it is desired that after the all-case surveillance condition for approval, IGU become a standard csDMARDs all over the world which was made in Japan.

Abstract
BACKGROUND AND AIM OF THE WORK In OSAHS, the hypoxia and reoxygenation cicles, maintain a state of oxidative stress, which seems to cause a change in the oxidative balance. Our aim is to compare the markers of oxidative stress with audiological findings and OSAHS severity, in OSAHS patients untreated and also treated ones, with cysteine and superoxide dismutase. METHODS 65 patients (42 Men, 23 Women) with 30-65 years age range have been enrolled, with a mean age of 52.6 ± 13.3 years with moderate OSAHS. We have analyzed plasma and lymphocyte markers of oxidative stress (glutathione, thioredoxin and heat shock protein) and they were underwent tonal audiometry. Patients were divided in two groups: Group A (32 patients) included patients treated for 8 weeks with cysteine and superoxide dismutase; Group B (33 patients) included patients untreated. RESULTS The research showed a significant increase in reduced glutathione levels (p<0.05) in OSAHS patients treated; conversely, it showed a decrease of oxidized glutathione level (p<0.05) in treated patients than OSAHS untreated ones. The thioredoxin values, in untreated OSAHS patients, appear to be reduced than in OSAHS patients treated (p<0.05), and that the heat shock protein values were more elevated in untreated OSAHS patients (p<0.05). Finally, it was found that a correlation exists between the severity of OSAHS and auditory dysfunction. CONCLUSIONS The study of the oxidative stress markers has produced results which lead to support the idea that, in a personalized therapy context, the use of antioxidant therapy can cooperate effectively the first choice treatment.

Abstract
Many herbal medicines are effective anti-inflammatory agents and may therefore suppress the development of hepatocellular carcinoma (HCC). Recently, treatment with a single-tablet regimen containing ledipasvir and sofosbuvir resulted in high rates of sustained virologic response among patients with hepatitis C virus genotype 1 infection who did not respond to prior interferon-based treatment. Patients with chronic hepatitis C are expected to receive this treatment worldwide. However, many patients have hepatitis-like fatty liver and nonalcoholic steatohepatitis. A strategy to prevent the development of HCC in this subgroup of patients is urgently required. Whether herbal medicines can suppress the development of HCC remains to be established. However, herbal medicines are effective anti-inflammatory agents and may inhibit the development of HCC. Clinical trials exploring the effectiveness of herbal medicines in the prevention and treatment of HCC are therefore warranted. The current lack of knowledge and of educational programs is a barrier to increasing the use of potentially effective herbal medicines and performing prospective clinical trials.

Abstract
AIMS Vitamin D (VD) deficiency has become a worldwide epidemic, particularly affecting African Americans (AA). VD deficiency has been implicated in the excessive rate of complications associated with diabetes in AA. Blood levels of VD binding protein (VDBP) and glutathione (GSH) are lower in AA compared with those in Caucasians. This study tested the hypothesis that lower GSH levels are linked to VDBP and VD deficiency in AA-type 2 diabetic (AA-T2D) patients. Blood was analyzed from T2D and nondiabetic subjects (N). Experiments examining GSH deficiency and l-cysteine (LC) supplementation were performed using THP-1 monocytes. RESULTS Plasma levels of LC, GSH, VDBP, and VD were significantly lower in AA-T2D compared with age-matched AA-N or Caucasian-T2D. Lower levels of LC and GSH showed a significant positive correlation with lower VDBP and VD levels in AA-T2D. GSH deficiency investigated using an antisense approach depleted VDBP/vitamin D receptor (VDR); LC supplementation caused significant upregulation of GSH and of VDBP/VDR, while supplementation with VD+LC caused a significantly greater GSH and VDBP/VDR upregulation compared with that of VD alone in monocytes. INNOVATION AND CONCLUSION The reported observations suggest that VD deficiency may be linked to GSH and LC status and lead to a novel hypothesis that supplementation with LC in combination with VD will be effective in increasing VD levels and reducing health disparities in AA.

Abstract
We report two cases of bucillamine-induced bullous reactions with keratinocyte necrosis. The first patient, a 27-year-old woman, developed toxic epidermal necrolysis (TEN) over her whole body after taking bucillamine 300 mg/day for seven days. The second patient, a 63-year-old woman, developed several bullous erythemas on the mucous membranes and legs after taking bucillamine for more than two years. The fixed drug eruptions were diagnosed based on a provocation test in addition to clinical and histopathologic findings. These cases highlight the importance of considering fixed drug eruption as well as TEN in the differential diagnosis of bucillamine-induced bullous drug eruption.

Abstract
OBJECTIVE To compare the efficacy and safety of Stronger Neo-Minophagen C (SNMC) in the treatment of chronic hepatitis B. METHODS We searched MEDLINE, EMBASE, CBM, and CNKI up to December, 2012 to identify randomized controlled trials (RCTs) comparing Stronger Neo-Minophagen C plus other therapy versus others therapy for chronic hepatitis B. Two reviewers independently assessed the risk of bias and extracted data from the included RCTs according to the Cochrane Reviewers Handbook 5.1.0. Meta-analyses were performed using RevMan 5.1 software. RESULTS Thirty-one trials involving 2753 patients were included in the analysis. The results of meta-analyses showed that SNMC improved hepatic functions of the patients by reducing ALT (MD=-31.63, 95% CI: -51.57, -11.70), AST (MD=-18.70, 95% CI:-25.10, -12.30), TBIL (MD=-12.17, 95% CI: -17.63,-6.71), HA (MD=-94.89, 95% CI: -125.19, -64.60), LN (MD=-40.08, 95% CI: -52.38,-27.78), IV-C (MD=-50.61, 95% CI:-63.40, -37.81), PC-III (MD=-49.71, 95% CI: -71.72, -27.69) as compared with the control group. The seroconversion rate of HBeAg (OR=2.23, 95% CI: 1.70, 2.94), HBV-DNA (OR=2.20, 95% CI: 1.70, 2.84), HBsAg (OR=2.25, 95% CI: 1.24 , 4.07), total response rate (OR=4.37, 95% CI: 2.62, 7.28), and ALT normalization rate (OR=3.77, 95% CI: 2.46, 5.79) were all significantly higher in the combined therapy group than in the control group. CONCLUSION SNMC plus other therapy is more effective than other therapy alone in improving the hepatic function and hepatic fibrosis and increasing hepatic seroconversion rate in patients with chronic hepatitis B without causing serious adverse events. But considering the low quality of the included studies, the results should be interpreted with caution and awaits further confirmation by high-quality, large-scale RCTs.

Abstract
Garlic (Allium sativum L. fam. Alliaceae) is one of the most researched and best-selling herbal products on the market. For centuries it was used as a traditional remedy for most health-related disorders. Also, it is widely used as a food ingredient--spice and aphrodisiac. Garlic's properties result from a combination of variety biologically active substances which all together are responsible for its curative effect. The compounds contained in garlic synergistically influence each other so that they can have different effects. The active ingredients of garlic include enzymes (e.g. alliinase), sulfur-containing compounds such as alliin and compounds produced enzymatically from alliin (e.g. allicin). There is a lot of variation among garlic products sold for medicinal purposes. The concentration of Allicin (main active ingredient) and the source of garlic's distinctive odor depend on processing method. Allicin is unstable, and changes into a different chemicals rather quickly. It's documented that products obtained even without allicin such as aged garlic extract (AGE), have a clear and significant biological effect in immune system improvement, treatment of cardiovascular diseases, cancer, liver and other areas. Some products have a coating (enteric coating) to protect them against attack by stomach acids. Clinically, garlic has been evaluated for a number of purposes, including treatment of hypertension, hypercholesterolemia, diabetes, rheumatoid arthritis, cold or the prevention of atherosclerosis and the development of tumors. Many available publications indicates possible antibacterial, anti-hypertensive and anti-thrombotic properties of garlic. Due to the chemical complexity of garlic and the use of different processing methods we obtain formulations with varying degrees of efficacy and safety.

Abstract
Skin aging is a multisystem degenerative process caused by several factors, such as, UV irradiation, stress, and smoke. Furthermore, wrinkle formation is a striking feature of photoaging and is associated with oxidative stress and inflammatory response. In the present study, we investigated whether caffeic acid, S-allyl cysteine, and uracil, which were isolated from garlic, modulate UVB-induced wrinkle formation and effect the expression of matrix-metalloproteinase (MMP) and NF-κB signaling. The results obtained showed that all three compounds significantly inhibited the degradation of type І procollagen and the expressions of MMPs in vivo and attenuated the histological collagen fiber disorder and oxidative stress in vivo. Furthermore, caffeic acid and S-allyl cysteine were found to decrease oxidative stress and inflammation by modulating the activities of NF-κB and AP-1, and uracil exhibited an indirect anti-oxidant effect by suppressing cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) expressions levels and downregulating transcriptional factors. These results suggest that the anti-wrinkle effects of caffeic acid, S-allyl cysteine, and uracil are due to anti-oxidant and/or anti-inflammatory effects. Summarizing, caffeic acid, S-allyl cysteine, and uracil inhibited UVB-induced wrinkle formation by modulating MMP via NF-κB signaling.

Abstract
Disease-modifying antirheumatic drugs (DMARDs) have largely contributed to recent paradigm shift of rheumatoid arthritis (RA) treatment strategy. DMARDs can be indicated for all RA patients and early use of DMARDs after diagnosis of RA is recommended. Individual DMARDs have common characteristics. Understanding these characteristics is very important in treating RA. As for safety, the pattern of adverse reactions (ADRs) associated with DMARDs has been generally understood. It is necessary to select DMARDs and follow up patients with recognition of the pattern of ADRs. Regular monitoring is also essential to ensure the safety of DMARDs. This chapter deals with some major DMARDs in Japan, including methotrexate, which is indispensable in current RA treatment; salazosulfapyridine and bucillamine; tacrolimus, which is recently increasing in use; and iguratimod, which became available in 2012.

Abstract
Islet-level oxidative stress has been proposed as a trigger for type 1 diabetes (T1D), and release of cytokines by infiltrating immune cells further elevates reactive oxygen species (ROS), exacerbating β cell duress. To identify genes/mechanisms involved with diabetogenesis at the β cell level, gene expression profiling and targeted follow-up studies were used to investigate islet activity in the biobreeding (BB) rat. Forty-day-old spontaneously diabetic lymphopenic BB DRlyp/lyp rats (before T cell insulitis) as well as nondiabetic BB DR+/+ rats, nondiabetic but lymphopenic F344lyp/lyp rats, and healthy Fischer (F344) rats were examined. Gene expression profiles of BB rat islets were highly distinct from F344 islets and under-expressed numerous genes involved in ROS metabolism, including glutathione S-transferase (GST) family members (Gstm2, Gstm4, Gstm7, Gstt1, Gstp1, and Gstk1), superoxide dismutases (Sod2 and Sod3), peroxidases, and peroxiredoxins. This pattern of under-expression was not observed in brain, liver, or muscle. Compared with F344 rats, BB rat pancreata exhibited lower GST protein levels, while plasma GST activity was found significantly lower in BB rats. Systemic administration of the antioxidant N-acetyl cysteine to DRlyp/lyp rats altered abundances of peripheral eosinophils, reduced severity of insulitis, and significantly delayed but did not prevent diabetes onset. We find evidence of β cell dysfunction in BB rats independent of T1D progression, which includes lower expression of genes related to antioxidative defense mechanisms during the pre-onset period that may contribute to overall T1D susceptibility.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is highly malignant and metastatic. Currently, there is no effective chemotherapy for patients with advanced HCC leading to an urgent need to seek for novel therapeutic options. We aimed to investigate the effect of a garlic derivative, S-allylcysteine (SAC), on the proliferation and metastasis of HCC. METHODOLOGY/PRINCIPAL FINDINGS A series of in vitro experiments including MTT, colony-forming, wound-healing, invasion, apoptosis and cell cycle assays were performed to examine the anti-proliferative and anti-metastatic effects of SAC on a metastatic HCC cell line MHCC97L. The therapeutic values of SAC single and combined with cisplatin treatments were examined in an in vivo orthotopic xenograft liver tumor model. The result showed that the proliferation rate and colony-forming abilities of MHCC97L cells were suppressed by SAC together with significant suppression of the expressions of proliferation markers, Ki-67 and proliferating cell nuclear antigen (PCNA). Moreover, SAC hindered the migration and invasion of MHCC97L cells corresponding with up-regulation of E-cadherin and down-regulation of VEGF. Furthermore, SAC significantly induced apoptosis and necrosis of MHCC97L cells through suppressing Bcl-xL and Bcl-2 as well as activating caspase-3 and caspase-9. In addition, SAC could significantly induce the S phase arrest of MHCC97L cells together with down-regulation of cdc25c, cdc2 and cyclin B1. In vivo xenograft liver tumor model demonstrated that SAC single or combined with cisplatin treatment inhibited the progression and metastasis of HCC tumor. CONCLUSIONS/SIGNIFICANCE Our data demonstrate the anti-proliferative and anti-metastatic effects of SAC on HCC cells and suggest that SAC may be a potential therapeutic agent for the treatment of HCC patients.

Abstract
BACKGROUND AND AIMS Recent studies have shown that activated pancreatic stellate cells (PSCs) play a major role in pancreatic fibrogenesis. We aimed to study the effect of L-cysteine administration on fibrosis in chronic pancreatitis (CP) induced by trinitrobenzene sulfonic acid (TNBS) in rats and on the function of cultured PSCs. METHODS CP was induced by TNBS infusion into rat pancreatic ducts. L-cysteine was administrated for the duration of the experiment. Histological analysis and the contents of hydroxyproline were used to evaluate pancreatic damage and fibrosis. Immunohistochemical analysis of α-SMA in the pancreas was performed to detect the activation of PSCs in vivo. The collagen deposition related proteins and cytokines were determined by western blot analysis. DNA synthesis of cultured PSCs was evaluated by BrdU incorporation. We also evaluated the effect of L-cysteine on the cell cycle and cell activation by flow cytometry and immunocytochemistry. The expression of PDGFRβ, TGFβRII, collagen 1α1 and α-SMA of PSCs treated with different concentrations of L-cysteine was determined by western blot. Parameters of oxidant stress were evaluated in vitro and in vivo. Nrf2, NQO1, HO-1, IL-1β expression were evaluated in pancreas tissues by qRT-PCR. RESULTS The inhibition of pancreatic fibrosis by L-cysteine was confirmed by histological observation and hydroxyproline assay. α-SMA, TIMP1, IL-1β and TGF-β1 production decreased compared with the untreated group along with an increase in MMP2 production. L-cysteine suppressed the proliferation and extracellular matrix production of PSCs through down-regulating of PDGFRβ and TGFβRII. Concentrations of MDA+4-HNE were decreased by L-cysteine administration along with an increase in GSH levels both in tissues and cells. In addition, L-cysteine increased the mRNA expression of Nrf2, NQO1 and HO-1 and reduced the expression of IL-1β in L-cysteine treated group when compared with control group. CONCLUSION L-cysteine treatment attenuated pancreatic fibrosis in chronic pancreatitis in rats.

Abstract
The primary goal in the treatment of rheumatoid arthritis (RA) is to maintain good quality of life by preventing joint destruction and avoiding disability. For this purpose, all patients with the diagnosis of RA should be treated by disease-modifying antirheumatic drugs (DMARDs) including biologic DMARDs and non-biologic DMARDs. All DMARDs are expected to prevent the progression of bone and cartilage destruction of RA patients from the results of in vitro research, and prevention of joint destruction is confirmed in vivo in all biologic DMARDs, but not in all non-biologic DMARDs. In this chapter, we would like to review the results of basic researches and clinical studies to demonstrate the prevention of joint destruction by non-biologic DMARDs that have been frequently used I daily practice.

Abstract
BACKGROUND Children with edematous severe acute malnutrition (SAM) produce less cysteine than do their nonedematous counterparts. They also have marked glutathione (GSH) depletion, hair loss, skin erosion, gut mucosal atrophy, and depletion of mucins. Because GSH, skin, hair, mucosal, and mucin proteins are rich in cysteine, we hypothesized that splanchnic extraction and the efficiency of cysteine utilization would be greater in edematous than in nonedematous SAM. OBJECTIVE We aimed to measure cysteine kinetics in childhood edematous and nonedematous SAM. DESIGN Cysteine flux, oxidation, balance, and splanchnic uptake (SPU) were measured in 2 groups of children with edematous (n = 9) and nonedematous (n = 10) SAM at 4.4 ± 1.1 d after admission (stage 1) and at 20.5 ± 1.6 d after admission (stage 2) when they had replenished 50% of their weight deficit. RESULTS In comparison with the nonedematous group, the edematous group had slower cysteine flux at stage 1 but not at stage 2; furthermore, they oxidized less cysteine at both stages, resulting in better cysteine balance and therefore better efficiency of utilization of dietary cysteine. Cysteine SPU was not different between groups but was ∼45% in both groups at the 2 stages. CONCLUSION These findings suggest that children with edematous SAM may have a greater requirement for cysteine during early and mid-nutritional rehabilitation because they used dietary cysteine more efficiently than did their nonedematous counterparts and because the splanchnic tissues of all children with SAM have a relatively high requirement for cysteine. This trial was registered at clinicaltrials.gov as NCT00069134.

Abstract
OBJECTIVE To evaluate the effect of decoction of turtle shell for anti-fibrosis combined with stronger neo-minophagen C on the indices of hepatic fibrosis in chronic hepatitis B. METHOD The 94 cases of chronic viral hepatitis B patients were randomly divided into two groups. The treatment group was treated with stronger neo-minophagen C 100 mL dissolved in 10% dextrose 250 ml once a day intravenously, combined with decoction of turtle shell for anti-fibrosis one powder daily. And the control group was treated with stronger neo-minophagen C alone, 3 months as a course. Liver fibrosis indexes and liver function index were tested for two groups of patients before and after the treatment. RESULT Both the difference of liver fibrosis indexes between the treatment group and the control group and before and after the treatment in the treatment group had statistical significance (P < 0.01). Both the difference of liver function index between the treatment group and the control group and before and after the treatment in the treatment group had statistical significance (P < 0.01). The basic cure rate and total effective rate were 40% and 84.0% in the treatment group and 27.27% and 86.18% in the control group respectively with significant difference. The treatment group was superior to control group in the mean size of diameter of portal vein and the thickness of spleen (P < 0.01). CONCLUSION Decoction of turtle shell for anti-fibrosis combined with stronger neo-minophagen C could significantly improve the clinical efficacy and the liver fibrosis indexes and liver function index in chronic hepatitis B.

Abstract
It has been shown that the administration of 0,5 ml of 5 mM aqueous solution of dinitrosyl-iron complexes (DNIC) with cysteine alleviated the development of experimental endometriosis in rats induced by surgical way: the size of endometriomes decreased 1.85 times when the DNIC was added every day during 10 days. The effect was suggested to be due to cytotoxic action of NO molecules and nitrosonium ions (NO+) released from rapidly decomposed DNIC in animal organism on endometriome tissues.

Abstract
Prophylactic potential of synthetic bacterial lipopeptide and a TLR2 agonist, Pam3Cys was first evaluated against experimental visceral leishmaniasis in rodent model. After establishing the potential its effect on therapeutic efficacy of miltefosine was also studied. Pam3Cys showed 74.64% inhibition in parasitic establishment when administered by ip route at a dose of 100 μg/animal spaced at two weeks, i.e. on day -7 and +7 of challenge with Leishmania donovani amastigotes. However, when aforesaid dose of Pam3Cys was given with sub-curative dose of miltefosine (2.5 mg/kg for 5 days) its efficacy enhanced from 49.80% to 92.25%. These findings revealed that this lipopeptide has potential protective efficacy which significantly enhanced the therapeutic efficacy of miltefosine used at low dose against Leishmania infection and warrants detailed investigations on its possible immunopotentiatory actions.

Abstract
BACKGROUND The transgenic adenocarcinoma of mouse prostate (TRAMP) model is by far the most practical transgenic model for preclinical prostate cancer chemoprevention studies. It is critical to characterize the prostate lobe-specificity of lesion lineages to consolidate the advantages of this model and minimize its limitations for chemoprevention studies. METHODS We dissected dorsolateral (DLP), ventral (VP), and anterior prostate (AP) lobes, and macroscopic tumors from 90 male C57BL/6J TRAMP mice at 22-24 weeks of age (WOA) and analyzed lesions by histological, biochemical and proteomic approaches. To determine whether methylseleninic acid (MSeA) led to a deletion of initiated cells, we gave oral MSeA to TRAMP mice from 5 to 23 WOA or from 5 to 15 WOA and analyzed lesions at 23 WOA. RESULTS All tumors (n = 18) were T-antigen(+), synaptophysin (SYP)(+), androgen-receptor(-), and E-cadherin(-) poorly differentiated neuroendocrine carcinomas (NE-Ca). They were traceable most frequently to VP (66.7%) and rarely to DLP (11.1%) and AP (5.6%) with an estimated life-time incidence of 1 out of 3 mice. In DLP, epithelial lesions ranged from mild-to-severe atypical hyperplasia, with T-antigen(+), SYP(-), androgen-receptor(+), and E-cadherin(+). Proteomic profiling revealed many molecular differences between VP and DLP. In MSeA experiment, 6 out of 19 (31.5%) mice developed NE-Ca in the control group, only 2 in each MSeA group of 17-18 mice (11.1-11.8%) bore a detectable NE-Ca. CONCLUSION The C57BL/6J TRAMP mouse represents at least two lineages of prostate carcinogenesis. Chemoprevention studies should incorporate this knowledge for efficacy assessment and molecular target validations.

Abstract
To retrospectively evaluate the efficacy and safety of combination therapy with tacrolimus (TAC) and other disease-modifying antirheumatic drugs (DMARDs). One hundred fifteen rheumatoid arthritis (RA) patients treated with tacrolimus were enrolled in this retrospective analysis. We collected clinical information, including patient background, treatment efficacy (evaluated using the DAS score), and adverse events observed. Multiple logistic regression analysis was conducted to analyze factors contributing to clinical response and adverse effects. The disease activity score of 28 joints (DAS28) improved significantly at 24 weeks, and continuation rate at 1 year was 57.9%. There was no difference in continuation rate between different DMARD combinations, and not only methotrexate (MTX) but also bucillamine (BUC) and salazosulfapyridine (SSZ) were effective combination partners with TAC. No serious adverse events were observed, and no different inefficacy or safety was observed between non-elderly (<65 years old) and elderly (≥65 years old) RA patients. By conducting multiple logistic regression analysis, combination therapy with MTX and TAC, the number of baseline DMARDs (specifically, ≥3), and old age were identified as risk factors for adverse events. Our findings indicate that TAC is a valuable DMARD for second-line combination therapy in RA.
