Abstract
Cnidium officinale Makino (COM), a perennial herbaceous plant in the Apiaceous family, widely distribute in Eastern Asia and Asia-Temperate. It has a long history application as a traditional medicine for invigorating the blood and removing blood stasis, and also has been employed to diet, pesticide, herbal bathing materials, the cosmetic and skin care industry. However, there has been no associated review of literature in the past half a century (1967-2023). By searching the international authoritative databases and collecting 229 literatures closely related to COM, herewith a comprehensive and systematic review was conducted. The phytology includes plant distribution and botanical characteristics. The phytochemistry covers 8 major categories, 208 compounds in total, and the quantitative determination of 14 monomer compounds, total polyphenols and total flavonoids. The clinical trial in pregnant women and toxic experiments in mice, the pharmacology of 7 aspects and 82 frequently used prescriptions are summarized. It is expected that this paper will provide forward-looking scientific thinking and literature support for the further modern research, development and utilization of COM.

[PMID: 34936984 DOI: 10.1123/pes.2020-0193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2020] [Revised: 09/22/2021] [Accepted: 11/14/2021] [Indexed: 11/18/2022]
Abstract
PURPOSE This study evaluated the effects of 12 weeks of karate training on cardiometabolic parameters, oxidative stress, and inflammation in adolescents with overweight and obesity. METHOD Seventy adolescents were randomized into 2 groups: control received nutritional and psychological interventions once a week for 12 weeks, and treatment received nutritional and psychological interventions once a week, plus 3 karate sessions per week, for 12 weeks. The main outcome measure was improvement in cardiometabolic parameters, oxidative stress, and inflammation. RESULTS After the intervention period, the treatment group showed a reduction in resting heart rate (77.86 [10.89]), high-density lipoprotein cholesterol (40.86 [8.31]), and triglycerides (75.18 [32.29]) and an increase in low-density lipoprotein cholesterol (95.64 [42.53]) in relation to pretraining. Regarding oxidative stress markers, there was a reduction in protein carbonylation (0.07 [0.06]) and nitric oxide (1.39 [1.11]) and an increase in superoxide dismutase (0.68 [0.31]) and glutathione (0.11 [0.08]) compared with pretraining. With respect to inflammation, adiponectin increased (14.54 [5.36]) after the intervention when compared with preintervention. CONCLUSION The study concluded that the intervention may improve cardiometabolic parameters, oxidative stress, and inflammation in adolescents with overweight and obesity. Long-term effects need to be evaluated.

Abstract
OBJECTIVES The aim of this study was to investigate the effects of aquatic exercise on mental health, functional autonomy and oxidative stress parameters in depressed elderly individuals. METHODS Initially, ninety-two elderly individuals were included in the study and were allocated into the depression group (n=16) and nondepression group (n=14). Both groups engaged in the aquatic exercise program for 12 weeks, including two weekly sessions (45 min/session) at a low intensity (between 50% and 60% of maximal heart rate or Borg scale scores of 13 to 14) throughout the intervention. All outcomes were evaluated at baseline and 12 weeks later. RESULTS The patients were 63.5±8.8 years old. The following scores were decreased after training in the depressed group: depression (53%), anxiety (48%), and Timed Up & Go (33%). The following scores increased: Berg Balance Scale (9%) and flexibility (44%). Regarding the blood-based parameters, there were decreases in protein carbonylation (46%) and nitric oxide (60%) and increases in glutathione (170%) and superoxide dismutase (160%) in the depression group (p<0.005). CONCLUSIONS The aquatic exercise program reduces depression and anxiety, improves functional autonomy and decreases oxidative stress in depressed elderly individuals.

Physical Training Regulates Mitochondrial Parameters and Neuroinflammatory Mechanisms in an Experimental Model of Parkinson's Disease. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2015; 2015:261809. [PMID: 26448816 PMCID: PMC4581546 DOI: 10.1155/2015/261809] [Citation(s) in RCA: 51] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/24/2015] [Revised: 07/16/2015] [Accepted: 08/06/2015] [Indexed: 11/17/2022]
Abstract
This study aimed to evaluate the effects of two different protocols for physical exercise (strength and aerobic training) on mitochondrial and inflammatory parameters in the 6-OHDA experimental model of Parkinson's disease. Six experimental groups were used (n = 12 per group): untrained + vehicle (Sham), strength training + vehicle (STR), treadmill training + vehicle (TTR), untrained + 6-OHDA (U + 6-OHDA), strength training + 6-OHDA (STR + 6-OHDA), and treadmill training + 6-OHDA (TTR + 6-OHDA). The mice were subjected to strength or treadmill training for 8 weeks. PD was induced via striatal injection of 6-OHDA 24 h after the last exercise session. Mice were euthanized by cervical dislocation and the striatum and hippocampus were homogenized to determine levels of tyrosine hydroxylase (TH), nuclear factor kappa B (NF-κB) p65, and sirtuin 1 (Sirt1) by western blot; tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), IL-17, interferon-γ (IFN-γ), and transforming growth factor β1 (TGF-β1) levels by ELISA; NO content; and complex I (CI) activity. STR + 6-OHDA mice had higher TH levels and CI activity and lower NF-κB p65 and IFN-γ levels in the striatum compared to U + 6-OHDA mice, while TTR + 6-OHDA mice had higher Sirt1 levels and CI activity in both the striatum and the hippocampus, compared to U + 6-OHDA mice. Strength training increased CI activity and TH and Sirt1 levels and reduced NO, NF-κB p65, TNF-α, IFN-γ, IL-1β, and TGF-β1 levels in 6-OHDA mice, while treadmill exercise increased CI activity and NO, TH, and Sirt1 levels and reduced NF-κB p65, TNF-α, IFN-γ, and IL-1β levels. Our results demonstrated that both treadmill training and strength training promote neuroprotection, possibly by stimulating Sirt1 activity, which may in turn regulate both mitochondrial function and neuroinflammation via deacetylation of NF-κB p65. Changes in nitric oxide levels may also be a mechanism by which 6-OHDA-induced inflammation is controlled.

Abstract
In the present study, hydroxyapatite (HAP) nanoparticles of different particle sizes with high crystallinity and similiar structure were prepared by hydrothermal method. The crystal structure and particle size were characterized by X-ray diffraction pattern (XRD), transmission electron microscopy (TEM) and Fourier transform infrared (FT-IR) spectroscopy. Mung bean sprouts were first used as experimental models. Instead of by MTT assay, the cytoxicity of HAP nanoparticles were proved and evaluated by measuring the hypocotyle length of mung bean sprouts in the culture media. The result showed that the inhibition effect to the growth of mung bean sprouts enhanced when HAP nanoparticles existed. Culture media of HAP nanoparticles with different concentrations and particle sizes was prepared to investigate the level of inhibition effect to the growth of mung bean sprouts. The result found that hypocotyl length of mung bean sprouts were the shortest cultured in 5mg/mL culture media in which the HAP nanoparticles were prepared by hydrothermal method for 24h. It was concluded the inhibition effect depended on the amount of intracellular HAP nanoparticles. The nanostructure and Ca(2+) concentration were considered as the main factors to cause cell apoptosis which was the reason of inhibition. The study provided a preliminary perspective about biotoxicity of HAP nanomaterials to the plant growth.

Abstract
Cervical cancer is a major health problem worldwide and is the most frequent cause of cancer in women in India. Early detection and affordable drugs with clinical efficacy have to go hand-in-hand in order to comprehensibly address this serious health challenge. Plant-based drugs with potent anticancer effects should add to the efforts to find a cheap drug with limited clinical side effects. Keeping this very purpose in mind, an attempt has been made in this review to explore the potential of plant extracts or constituents known to exhibit antitumorigenic activity or exert cytotoxic effect in human cervical carcinoma cells. Alkaloids such as those isolated from C. vincetoxicum and T. Tanakae, naucleaorals A and B, isolated from the roots of N. orientalis, (6aR)-normecambroline, isolated from the bark of N. dealbata appear promising in different human cervical carcinoma cells with the IC50 of 4.0-8 μg/mL. However, other compounds such as rhinacanthone and neolignans isolated from different plants are not far behind and kill cervical cancer cells at a very low concentrations. Among plant extracts or its constituents that enhance the effect of known anticancer drugs, noni, derived from the plant M. citrifolia perhaps is the best candidate. The cytotoxic potency and apoptotic index of cisplatin was found to significantly enhanced in combination with noni in different human cervical carcinoma cells and it therefore holds significance as promising herbal-based anticancer agent. However, efficacy needs to be further investigated in various cervical cell lines and more importantly, in in vivo cervical cancer models for possible use as an alternative and safe anticancer drug.

Abstract
In spite of billions of dollars spent on cancer research each year, overall cancer incidence and cancer survival has not changed significantly in the last half century. Instead, the recent projection from the World Health Organization suggests that global cancer incidence and death is expected to double within the next decade. This requires an "out of the box" thinking approach. While traditional medicine used for thousands of years is safe and affordable, its efficacy and mechanism of action are not fully reported. Demonstrating that traditional medicine is efficacious and how it works can provide a "bed to bench" and "bench to bed" back approach toward prevention and treatment of cancer. This current review is an attempt to describe the contributions of traditional Korean medicine (TKM) to modern medicine and, in particular, cancer treatment. TKM suggests that cancer is an outcome of an imbalance of body, mind, and spirit; thus, it requires a multimodal treatment approach that involves lifestyle modification, herbal prescription, acupuncture, moxibustion, traditional exercise, and meditation to restore the balance. Old wisdoms in combination with modern science can find a new way to deal with the "emperor of all maladies."

Abstract
X1-homologous genes (XHS) encode plant-specific proteins containing three major domains (XH, XS, zf-XS), but their functions are largely unknown. We report the systematic identification and characterization of XHS genes in the rice genome. Eleven putative XHS protein sequences (OXHS1-11) were identified in the sequenced genome of Oryza sativa japonica cv. Nipponbare, and these sequences, along with other plant XHS homologues, were classified into five subgroups based on phylogenetic analysis. Distinct diversification of the XHS proteins occurred between monocotyledon and dicotyledon plants. The OXHS family has diverse exon-intron structures and organizations of putative domains and motifs. The OXHS proteins showed no transactivation activity, and no interaction between the XH domain and the XS domain in yeast. Four representative OXHS proteins were targeted to cytoplasm, which contradicts the previous speculation that XHS proteins are putative transcription factors. All the OXHS genes are predominantly expressed in floral organs, and some are expressed in a wide range of tissues or organs in indica rice Minghui 63. Nine OXHS genes are responsive to at least one of the abiotic stresses including drought, salt, cold, and abscisic acid treatment. Over-expression of one stress-responsive gene OXHS2 in rice resulted in reduced tolerance to salt and drought stresses. These results suggest that the OXHS family may be functionally diversified and some members of this family may play important roles in regulating stress tolerance in rice.

Cloning and differential expression of manganese superoxide dismutase (Mn-SOD) of Trichinella pseudospiralis. Parasitol Res 2007; 102:251-8.

Abstract
The complete coding sequence of manganese superoxide dismutase (Mn-SOD) of Trichinella pseudospiralis (Tp) was obtained and characterized for the first time by degenerative reverse transcription polymerase chain reaction (RT-PCR) and rapid amplification of complementary DNA ends (RACE) reactions. The open reading frame of Tp Mn-SOD contained 663 nucleotides, encoding 220 amino acid residues. This included the conserved histidine and aspartate residues for metal binding, cysteine residues for disulfide bond formation, and arginine residue for directing the superoxide ion to the protein. The presence of mitochondrial transit peptides and maturation cleavage site suggest that the cloned Tp Mn-SOD gene is a mitochondrial enzyme. It is a single copy gene containing three introns. Northern blotting suggested that the expression level of Mn-SOD is lower than Cu/Zn SOD in infective stage larvae. Semi-quantitative RT-PCR demonstrated that a single dominant transcript of Tp Mn-SOD was highly expressed in the infective-stage larvae but not in adult worms. The information provides a better understanding of the highly compartmentalized superoxide dismutases of adenophorean nematodes.
