Abstract
Obesity and low enzyme A disintegrin and metalloproteinase with thrombospondin type-1 motif-13 (ADAMTS13) activity have been linked to poor coronavirus disease 2019 (COVID-19). Given that obesity may influence ADAMTS13 activity, it is feasible; however, it remains unclear whether ADAMTS13 activity acts as a mediator between obesity and COVID-19 outcomes. We investigated the link between body mass index (BMI) and COVID-19 outcomes, using ADAMTS13 activity as a mediator. ADAMTS13 activity was measured in 86 hospitalized COVID-19 patients. BMI, ADAMTS13 activity, and COVID-19 outcomes were assessed. Obese patients had a high odds ratio for low ADAMTS13 levels. When different levels of ADAMTS13 activity were considered, the severity of COVID-19 in obese patients was 4.5 times that in the normal BMI group. Furthermore, increased coagulopathy indicators correlated with low ADAMTS13 activity. Patients with elevated ALT and AST levels showed a 3 to 4-fold increase in the chances of low ADAMTS13 activity (OR:3.19, 95% CI:1.22-8.90, P = .021; OR:2.17, 95% CI:0.91-5.27, P = .082, respectively). When ADAMTS13 activity was considered, obese patients had greater COVID-19 severity and slower viral clearance than those with normal BMI. Low ADAMTS13 activity and impaired liver function are associated with poor COVID-19 outcomes. These findings encourage researchers to use molecular component identification to study the effects of obesity on the von Willebrand factor (VWF)/ADAMTS13 axis, COVID-19 pathogenesis, and outcomes.

Abstract
BACKGROUND An alarming number of zinc oxide nanoparticles (ZnO-NPs) have leaked into the environment, endangering the tissues of many living creatures, due to the recent surge in their use in several items. Through intra-peritoneal injection, this research intends to examine the impact of ZnO-NPs on the hepatic and gastrointestinal structures of male albino mice. METHOD For seven and 14 days, animals were given 0.1 ml of 100 and 200 mg kg-1 of 50 nm-size ZnO-NPs, respectively. In contrast, those in the control group were given only water and food. RESULT The results demonstrated that the treated mice's livers underwent functional changes and histological damage. After seven and 14 days, there was a notable rise in the average levels of the glutamate-oxaloacetate transaminase and glutamate-pyruvate transaminase enzymes in comparison to the control group (p≤0.05). Concentration time determines the magnitude of this impact. When enzyme levels vary, it means the liver isn't working properly. Histological changes in the liver, such as necrosis, destruction of hepatocyte membranes, widening of sinusoidal spaces and vacuolation of their cytoplasm, vascular congestion, and an increased number of Kupffer cells, were induced in mice treated with ZnO-NPs at two studied concentrations (100 and 200 mg/kg) for seven and 14 days, respectively. These effects were time-dose-dependent, according to the results of hematoxylin-eosin staining of liver tissue images.

Abstract
BACKGROUND The present study aimed to explore the quantitative effects of sodium-glucose cotransporter-2 (SGLT-2) inhibitors on liver functions in patients with nonalcoholic fatty liver disease (NAFLD). RESEARCH DESIGN AND METHODS A total of 4771 patients with NAFLD were included for analysis by means of nonlinear mixed effect modeling, where the change rates of liver functions were taken as the evaluation indexes so as to eliminate the potential baseline effects. RESULTS For ALT and AST, the Emax of SGLT-2 inhibitors was -17.8% and -13.9%, respectively, and the ET50 was 6.86 weeks and 10 weeks, respectively. Furthermore, the duration time to achieve 25%, 50%, 75%, and 80% Emax were 2.3 weeks, 6.86 weeks, 20.6 weeks, 27.5 weeks in ALT, 3.4 weeks, 10 weeks, 30 weeks, 40 weeks in AST, respectively. Thus, to realize the plateau period (80% of Emax) of SGLT-2 inhibitors on ALT and AST in patients with NAFLD, 100 mg/day canagliflozin (or 10 mg/day dapagliflozin or 10 mg/day empagliflozin) needs to be taken for 20.6 weeks and 30 weeks, respectively. CONCLUSIONS The present study explored the quantitative effects of SGLT-2 inhibitors on liver functions and recommends a therapeutic regimen in patients with NAFLD.

Abstract
Fennel seeds and flaxseed have been traditionally used against many medical ailments due to their medicinal characteristics. The aim of the study was to investigate the health properties of secoisolariciresinol diglucoside (SDG) and anethole from flaxseed and fennel seeds in rats fed with high-fat diet. Histopathological changes in the heart and liver were also examined. Sixty rats were divided into two main groups. Group I (10 rats) was used as a negative control group and fed on the basal diet only. Group II (50 rats) was fed a hypercholesterolemic diet but not given any drugs during the trial for 2 weeks. This group was further divided into five subgroups (10 rats each). One of them was fed on the basal diet and used as a positive control group. However, the other four subgroups were fed on basal diets and anethole (20 mg/kg/day, orally), SDG (20 mg/kg/day, orally), a mixture of anethole + SDG (10 + 10 mg/kg/day, orally), and atorvastatin (10 mg/kg/day, orally) for 6 weeks. Compared to control, treatment with a combination of anethole + SDG showed a significant (p ≤ .05) improvement in serum levels of triglyceride (TG) (137.88 ± 1.61 mg/dL), total cholesterol-(TC) (180.12 ± 8.99 mg/dL), LDL-C (46.40 ± 6.67 mg/dL), VLDL-C (11.81 ± 1.07 mg/dL), aspartate aminotransferase (AST) (75.97 ± 6.92 U/L), alanine aminotransferase (ALT) (34.83 ± 2.17 U/L), alkaline phosphatase (ALP) (130.65 ± 1.05 U/L), and malondialdehyde (MDA) (30.12 ± 1.89 mmol/g), and improved activities of catalase (70.99 ± 3.29 U/g) and superoxide dismutase (SOD) (35.13 ± 2.53 U/dL) enzymes while SDG and anethole group had relatively less impact. Atorvastatin also improved serum levels of triglyceride, total cholesterol, LDL-C, and VLDL-C significantly and rose serum high-density lipoprotein cholesterol (HDL-C) levels considerably meanwhile it had a minor but negative impact on AST, ALT, and ALP, and negligible impact on activities of MDA, CAT, and SOD enzymes compared to the positive control group. The study revealed that combining anethole and SDG may improve dyslipidemia, improve lipid profile, decrease risks of chronic heart diseases, increase HDL-C, and enhance antioxidant enzymes' activities.

Abstract
Micro- or nanoplastics, which are fragmented or otherwise tiny plastic materials, have long been a source of environmental worry. Microplastics (MPs) have been well documented to alter the physiology and behavior of marine invertebrates. The effects of some of these factors are also seen in larger marine vertebrates, such as fish. More recently, mouse models have been used to investigate the potential impacts of micro- and nanoplastics on host cellular and metabolic damages as well as mammalian gut flora. The impact on erythrocytes, which carry oxygen to all cells, has not yet been determined. Therefore, the current study aims to ascertain the impact of exposure to various MP exposure levels on hematological alterations and biochemical indicators of liver and kidney functions. In this study, a C57BL/6 murine model was concentration-dependently exposed to microplastics (6, 60, and 600 μg/day) for 15 days, followed by 15 days of recovery. The results demonstrated that exposure to 600 μg/day of MPs considerably impacted RBCs' typical structure, resulting in numerous aberrant shapes. Furthermore, concentration-dependent reductions in hematological markers were observed. Additional biochemical testing revealed that MP exposure impacted the liver and renal functioning. Taken together, the current study reveals the severe impacts of MPs on mouse blood parameters, erythrocyte deformation, and consequently, anemic patterns of the blood.

Abstract
Garlic is a common cooking ingredient and used in traditional medicine in Asian countries. There is a growing attention on garlic due to its preventive characteristics in cardiovascular diseases (CVDs). Many studies have reviewed the association between garlic intake and CVDs; however, no consistent conclusions have been drawn. New clinical trials have also been conducted and could contribute to more solid statements. In order to systematically review the reliability of previous studies regarding the implication of garlic in the management of CVDs, we performed in-depth meta-analysis using the most up-to-date randomized clinical trials (RCTs) data with more systematic controls. According to the 22 studies included, the effects of garlic intake on lowering total cholesterol (TC) and low-density lipoprotein (LDL) are more noticeable with lower dosage and longer duration, especially in patients with CVDs. In addition, subgroup analysis indicated that appropriate diet intervention could be an important control factor that should be taken into consideration in any future study designs.

Abstract
BACKGROUND The most dreaded pandemic grappling world now, the Coronavirus Disease 2019 (COVID-19), chiefly involves the respiratory system; nevertheless, it is a multisystem disorder. Its involvement of the hepatic system is considerable; however, still emerging are its clinical implications and the effects on morbidity and mortality. AIM The aim of this study is to report on the various aspects of its hepatic involvement by describing the alterations in tests of liver function and its significance in the disease outcome in a cohort of hospitalized COVID-19 patients at a tertiary center in northern India. METHODS This is a retrospective cohort study conducted in a tertiary-care hospital in northern India. All confirmed hospitalized COVID-19 cases aged 15 and above from Apr to Oct 2020 with no pre-existing liver disease were included. The primary endpoint was death at 28 days. Statistical analysis included descriptive analysis, sensitivity-specificity, and univariable and multivariable regression analysis as well as survival analysis. RESULTS A total of 708 patients with COVID-19 fulfilled the inclusion criteria included 561 (79.2%) males and 147 (20.8%) females. The median age was 49 (IQR = 25) years. Mild and moderate/severe disease were seen in 508 (71.8%) and 200 (28.2) patients, respectively. Serum bilirubin, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were elevated in 6.92%, 69.91%, and 80.22% of patients, respectively. In univariable logistic regression, AST [odds ratio; OR 1.008 95% CI (1.005-1.012) per 1 IU/L increase] and ALT [OR 1.005 95% CI (1.002-1.007) per 1 IU/L increase] were significantly associated with the odds of moderate to severe disease but only AST was significant after adjustment to age, sex, and comorbidity [adjusted odds ratio; aOR 1.007 95% CI (1.003-1.011) per 1 IU/L increase]. Serum albumin was negatively associated with the odds of moderate to severe disease and remained significant in the adjusted model [aOR 0.217 95%CI (0.149-0.316) per 1 g/dL increase].Ninety-six patients succumbed to illness [case fatality rate; CFR 13.6%). In adjusted Cox Proportional-Hazards Model for mortality, AST [adjusted hazard ratio; aHR 1.002 95% CI (1.000-1.003) per 1 IU/L increase] and serum albumin [aHR 0.396 95% CI (0.285-0.549) per 1 g/dL increase] showed significant association with mortality. CONCLUSION Liver function abnormalities are common in patients with COVID-19. In particular, AST and serum albumin levels are effective predictors of disease severity and mortality and can be used as markers of fatal disease in the management as well as prognostication of COVID-19.

Abstract
GSH-mediated liver biotransformation is a crucial physiological process demanding efficient research tools. Here, we report a type of amorphous FexMnyO nanoparticles (AFMO-ZDS NPs) as redox-activated probes for in vivo visualization of the dynamics of GSH-mediated biotransformation in liver with T1-weighted magnetic resonance imaging (MRI). This imaging technique reveals the periodic variations in GSH concentration during the degradation of AFMO-ZDS NPs due to the limited transportation capacity of GSH carriers in the course of GSH efflux from hepatocytes to perisinusoidal space, providing direct imaging evidence for this important carrier-mediated process during GSH-mediated biotransformation. Therefore, this technique offers an effective method for in-depth investigations of GSH-related biological processes in liver under various conditions as well as a feasible means for the real-time assessment of liver functions, which is highly desirable for early diagnosis of liver diseases and prompt a toxicity evaluation of pharmaceuticals.

Abstract
OBJECTIVE The aim of this study was to investigate whether there was a difference in laparoscopic sleeve gastrectomy (LSG) performed with either 10 mmHg or 13 mmHg intraabdominal pressures. Effects of these pressures on the internal jugular vein (IJV) diameter and flow along with the liver and kidney function tests were evaluated. MATERIALS AND METHODS The patients were divided into two groups with respect to the intraabdominal pressure performed during LSG (either 10 or 13 mmHg). The patients' age, comorbidities, surgical history, height, weight, body mass index, family history, duration of surgery, length of hospital stay, serum liver and kidney function tests (Urea, creatinine, Aspartate transaminase, Alanine transaminase, Gamma-glutamyltransferase, Alkaline phosphatase, bilirubin) and the right IJV diameter and flow measured by Duplex ultrasound before intubation (t1), 10 min after insufflation (t2), and at the end of insufflation (t3) were recorded. RESULTS Preoperative and postoperative kidney and liver function values of the patients in both groups were within the reference range. In both groups, there was a significant decrease in the IJV diameter and flow measurement values at t2 compared to t1, and a significant increase was observed at t3 compared to t2 (p < 0.05). The mean IJV diameter and flow were significantly higher in the 10 mmHg pressure group compared to the 13 mmHg group (p < 0.05). CONCLUSION Neither of the peak pressures performed intraabdominal during LSG caused an adverse effect on liver or kidney functions. Our study emphasizes that low insufflation pressure does not have an advantage in terms of liver and kidney functions. But laparoscopic sleeve gastrectomy with low intra-abdominal pressure may be beneficial especially in patients who require central vein catheterization during the operation. We consider that LSG performed with CO2 pneumoperitoneum at 10 mmHg is a safe, effective and feasible method that can facilitate the insertion of the intraoperative central venous catheter due to lesser charges in the IJV diameter and flow compared to the standard technique.

Abstract
<b>Background and Objective:</b> Tri-sodium Copper of chlorophyllins (Agri-Safe) is a novel biocide using recently to control the mosquitoes as a larvicide. Because, the lack of adequate data on the toxicity of this compound, more toxicological studies on this new compound are necessary. Therefore the study aimed to evaluate the adverse effects of this new insecticide and in comparison with the traditional insecticide Deltamethrin (DM). <b>Materials and Methods:</b> Twenty-five adult male rats were randomly divided into five groups. The first group was kept in control. The second and third groups were administered at doses of 0.59 and 0.24 mg kg<sup>1</sup> b.wt., of DM. The fourth and 5th groups were administrated at doses of 250 and 100 mg kg<sup>1</sup> b.wt. of Agri-Safe respectively. The administrations were orally by gavage for 90 consecutive days. The rats were humanly sacrificed and whole blood was collected for hematological parameters and bone marrow was collected for mutagenicity assays. <b>Results:</b> The estimated LD<sub>50</sub> of DM and Agri-Safe were 11.76 and more than 5000 mg kg<sup>1</sup> b.wt., respectively. Both insecticides induced slight hepatotoxicity but not nephrotoxicity. The high and low doses of DM induced prominent oxidative stress while Agri-Safe did not induce oxidative stress. The results of genotoxicity revealed that DM caused greater mutagenic effect at high and low doses, while Agri-Safe induced slight significant genotoxicity at high-dose only. <b>Conclusion:</b> It can be concluded that Deltamethrin (DM) can induce oxidative stress and prominent genotoxicity while tri-sodium copper of chlorophyllins has a low side effect and its effect is due to copper elements.

Abstract
Zamzam water is the most frequently used drinking water by millions of people in Saudi Arabia. It is carried all the time by millions of pilgrims to their home countries as gifts to close and near relatives and friends. Safety of constituents of Zamzam water is a vital health topic. British Broadcasting Corporation (BBC) raised many health concerns regarding the high serum arsenic and nitrate contents in Zamzam water that may cause cancer. It is role of scientific research to present scientific facts to relieve such concerns. Arsenic is a carcinogen while nitrate causes methemogloinemia that affect oxygen carriage by haemoglobin. An ethical committee approval was obtained. Eighteen white albino mice (40-45 g) were used in this study. Three experimental groups were allocated (six mice per group): tap water group, distilled water group and Zamzam water group. Our data revealed that Zamzam water exerts tissue-protective effects that contradict malignancy. Our data proved that Zamzam water is pathogen-free causing no bacterial growth on CLED agar colonies. Zamzam water consumption for three consecutive months in mice was quite safe for the general health and significantly decreased serum uric acid (p < 0.05) (possibly due to Zamzam-induced urine alkalinisation facilitating uric acid excretion). Regular Zamzam water consumption significantly decreased serum cholesterol (p < 0.05) and serum triglycerides (p < 0.05). Hypolipidemic effects of Zamzam water may be due to its high mineral content facilitating increased lipids metabolism. Our data confirmed safety of prolonged use of Zamzam water comparable to other drinking water types regarding the metabolic and synthetic functions of the liver. Nitrates in Zamzam water are thought to be an original constituent that may be useful (exerting vasodilation, antithrombotic, and immunoregulatory effects) and not harmless. This may occur due to high Zamzam content of calcium, magnesium and selenium. Histologically, our data confirmed that Zamzam water was quite safe to renal parenchyma and comparable to other types of drinking water. In conclusion, health concerns raised by BBC regarding Zamzam water safety were a good chance for fruitful scientific research investigations that confirmed safety and beneficial effects of Zamzam water for human health.

Abstract
Thalassemia is a major health problem in affected children due to iron overload, increased oxidative stress, atherogenic lipid profile and tissue-damage. This study aims at investigating the cardioprotective and tissue-protective benefits of Al-hijamah and their impact on cell-mediated immunity for treating thalassemic children. This study aimed also at investigating the tissue-clearance principle of Taibah mechanism: whenever pathological substances are to be cleared from the human body, Al-hijamah is indicated. Al-hijamah was done to thalassemic children (15 males and 5 females having a mean age of 9.07 ± 4.26 years) using sterile disposable sets in a complete aseptic hospital environment. Prior ethical committee agreement (in addition to written patient's consents) was obtained from Tanta Faculty of Medicine, Egypt. Twenty thalassemic children received iron chelation therapy plus Al-hijamah for one session (30-60 minutes) versus an age and sex-matched thalassemic control group treated with iron chelation therapy only. Al-hijamah is a quite safe outpatient hematological procedure that significantly decreased serum cholesterol (from 129.75 ± 3.67 to 103.5 ± 4.18 mg/dl) and decreased serum triglycerides (from 109.25 ± 8.96 to 91.95 ± 7.22 mg/dl). Interestingly, Al-hijamah exerted significant tissue-protective effects (it decreased serum GPT from 98.65 ± 12.27 to 71.65 ± 32.78 U/L and serum GOT from 96.35 ± 14.33 to 69.35 ± 34.37 U/L). Al-hijamah-induced ferritin excretion caused decreased serum ferritin (high serum ferritin negatively correlated with cell mediated immunity). Al-hijamah exerted cardioprotective and tissue-protective and hypolipidemic effects. Al-hijamah decreased serum cholesterol and is cardioprotective for thalassemic patients as it protects against atherogenesis and atherosclerosis. Medical practice of Al-hijamah is strongly recommended in hospitals. Al-hijamah cleared blood significantly from causative pathological substances e.g. serum ferritin resulting in enhanced cell-mediated immunity (in agreement with the evidence-based Taibah mechanism).

Abstract
BACKGROUND AND AIM Intoxication of arsenic in rats is known to result in neurological effects as well as liver and kidney dysfunction. Mucuna pruriens has been identified for its medicinal properties. The aim of the study was to investigate the protective effect of aqueous seed extract of M. pruriens on sodium arsenite-induced memory impairment, liver, and kidney functions in rats. MATERIALS AND METHODS The experiment was divided into short-term treatment (45 days) and long-term treatment (90 days), with each group divided into nine sub-groups consisting of six animals each. Sub-groups 1 and 2 served as normal, and N-acetylcysteine (NAC) controls, respectively. Sub-groups 3-9 received sodium arsenite in drinking water (50 mg/L). In addition, sub-group 4 received NAC (210 mg/kg b.wt) orally once daily, sub-groups 5-7 received aqueous seed extract of M. pruriens (350 mg/kg b.wt, 530 mg/kg b.wt, and 700 mg/kg b.wt) orally once daily and sub-groups 8 and 9 received a combination of NAC and aqueous seed extract of M. pruriens (350 mg/kg b.wt and 530 mg/kg b.wt) orally once daily. Following the treatment, the blood was drawn retro-orbitally to assess the liver (serum alanine transaminase [ALT], serum aspartate transaminase, and serum alkaline phosphatase) and kidney (serum urea and serum creatinine) functions. Learning and memory were assessed by passive avoidance test. Animals were sacrificed by an overdose of ketamine, and their Nissl stained hippocampal sections were analyzed for alterations in neural cell numbers in CA1 and CA3 regions. RESULTS In the short-term treatment, groups administered with M. pruriens 530 mg/kg b.wt alone and combination of NAC + M. pruriens 350 mg/kg b.wt exhibited a significant improvement in memory retention, less severe neurodegeneration, and decrease in serum ALT levels. In long-term treatment, groups administered with M. pruriens 700 mg/kg b.wt alone and combination of NAC+M. pruriens 350 mg/kg b.wt, respectively, showed better memory retention, decreased neural deficits, and reduced levels of kidney and liver enzymes. CONCLUSION The seed extract of M. pruriens showed significant enhancement in memory and learning. The number of surviving neurons in the CA1 and CA3 regions also increased on treatment with M. pruriens. Serum ALT, serum urea, and serum creatinine levels showed significant improvement on long-term treatment with M. pruriens.

Abstract
Human liver tissue is preferable over nonhuman liver tissue for preclinical drug screening, as the former can better predict side effects specific to humans. However, due to limited supply and ethical issues with human liver tissue, it is desirable to develop an animal model having functional human liver tissue. In this study, we have established an ectopic functional human liver tissue in a mouse model, using a minimally-invasive method. Firstly, a human liver tissue mass using HepG2 cells and poly(N-isopropylacrylamide) (PNIPAAm) incorporated poly(ethylene glycol)-alginate-gelatin (PAG) cryogel matrix was developed in vitro. It was later implanted in mouse peritoneal cavity using a 16 G needle. Viscoelastic nature along with low Young's modulus provided injectable properties to the cryogel. We confirmed minimal cell loss/death while injecting. Further, by in vivo study efficacy of both injectable and surgical implantation approaches were compared. No significant difference in terms of cell infiltration, human serum albumin (HSA) secretion and enzyme activity confirmed efficacy. This model developed using a minimally-invasive approach can overcome the limitations of surgical implantation due to its cost effective and user friendly nature.

Abstract
Morus nigra and Bauhinia variegata are used in the Egyptian folk medicine for their hypoglycemic effects. The standardized ethanolic extracts of both plants caused a significant decrease in fasting blood glucose level at two different doses (250 and 500 mg/kg) in streptozotocin-induced diabetic rats' model. Further, in vitro antioxidant activity and α-glucosidase inhibition assays were conducted as well as the measurement of insulin levels and the biomarkers for both liver and kidney functions in the treated animals. Beneficiary effects of BMLE and BVLE in the treatment of diabetes were found not to be limited to hypoglycemic effect but included preventing liver and kidney tissue damage that are associated with diabetes. A strong inhibition of the α-glucosidase enzyme by both extracts may be a contributing mechanism in the overall anti-diabetic effect that was observed. Further detailed study is needed in the future to explore the mechanism of action of both plants.

Abstract
AIMS Cyanobacteria are immense sources of several pharmacological active compounds such as flavonoids and carotenoids with anti-inflammatory and antioxidant activity. The potential therapeutic effect of two novel cyanobacterial isolates, Cronbergia siamensis (KY296358.1) and Sphaerospermopsis aphanizomenoides (KU212886.1), against hydrogen peroxide (H2 O2 )-induced oxidative stress damage in the rat model was determined in this study. METHODS AND RESULTS In vitro antioxidant activity of the two studied isolates was evaluated by radical scavenging assay and ferric reducing power. The possible prophylactic activity of S. aphanizomenoides (KU212886.1) against H2 O2 -induced oxidative stress in the rat model was assessed in vivo. Serum alanine transaminase and aspartate transaminase were measured for the liver functions in redox rats. Liver malondialdehyde (MDA), glutathione, oxidized glutathione, nitric oxide, superoxide dismutase (SOD) and catalase (CAT) were assessed as oxidative stress markers. The effect of S. aphanizomenoides on the transcripts level of superoxide dismutase (Mn-SOD) and catalase (CAT) genes in the rat's liver tissues was measured using qRT-PCR. Oral administration of S. aphanizomenoides extract in low and high doses (100, 200 mg kg-1 b.w) resulted in significant improvement in biochemical parameters of liver functions and oxidative stress markers. Also, the endogenous antioxidant defence enzymes and the expression of their related genes (Mn/SOD, CAT) were upregulated. Immunohistochemistry of Caspase-3, an apoptotic marker, showed potent amelioration in the liver tissues. CONCLUSIONS The novel isolate S. aphanizomenoides proved in vitro and in vivo antioxidant activity against redox rat model. SIGNIFICANCE AND IMPACT OF THE STUDY This isolate provides a new source of pharmacological compounds with great importance in pharmacological and medical fields.

Abstract
Simple Summary The liver is a multi-purpose organ, with involvement in bile secretion, and lipid, carbohydrate and protein metabolism, as well as a number of other metabolic functions. This organ can adapt easily to changes in feed and the environment. Being at the centre of a number of digestive, metabolic and productive activities, it is essential to have a better understanding of this organ and the factors affecting liver functionality. Abstract Despite having huge responsibilities in avian species, published reports on the influence of dietary factors and other possible constraints on the size, development and function of liver are limited. Consideration of the factors that could influence and alter liver function is therefore of critical relevance. In the current review, aspects of liver structure and function, and the influence of feed restriction, anti-nutritional factors, structural components and feed additives on liver are discussed. Effects of feed technology techniques such as thermal treatment and pelleting, feed particle size and whole grain feeding on the liver are also reviewed. A discussion of lipogenesis and lipid storage in poultry is presented to provide a better understanding and to differentiate the normal pathways of lipid metabolism from abnormal (i.e., disordered) pathways. The liver is the main site of fat synthesis in poultry, but under certain conditions, excessive fat can accumulate in the liver and cause problems. Factors contributing to the fatty liver syndrome are also examined.

Abstract
OBJECTIVES This study aimed at evaluating the effect of Legalon 70, a standard hepatic drug of silymarin, in reducing the toxic effects of hydrogen peroxide (H2O2) in broiler chickens. METHODS Twenty Ross broiler chickens of 30-day old were divided into four groups, Group 1 control, received drinking tap water, Group 2 treated with 0.5% H2O2 in drinking water, Group 3 treated with 0.5% H2O2 and 3 mg/Kg Legalon 70 daily, and Group 4 treated with a single oral dose of 3 mg/Kg Legalon 70 daily. After 4 weeks of the treatment, chickens were killed and the serum collected for the measuring of liver functions parameters, and the liver tissues used for processing the histological examination. RESULTS The results indicated that H2O2 treatment significantly elevated serum aspartate aminotransferase and alanine aminotransferase, and bilirubin level (direct and total) and decreased level of serum albumin comparing with control group. Treatment with Legalon 70 significantly reversed the H2O2-induced alteration and has positive effects on the liver functions parameters. Results of histopathology of H2O2-treated group showed severe vascular congestion, alveolar damage, and inflammatory cell infiltration, silymarin treatment blocked these changes and reduced the toxic effects of H2O2 toward liver cells. CONCLUSION We concluded that silymarin induces the liver function recovery and considered in the treatment of liver injury. Silymarin, a major component of milk thistle, has been used as a hepatoprotector.

Abstract
Cellular therapies hold promise to alleviate liver diseases. This study explored the potential of allogenic serum isolated from rat with acute CCl4 injury to differentiate adipose derived stem cells (ADSCs) towards hepatic lineage. Acute liver injury was induced by CCl4 which caused significant increase in serum levels of VEGF, SDF1α and EGF. ADSCs were preconditioned with 3% serum isolated from normal and acute liver injury models. ADSCs showed enhanced expression of hepatic markers (AFP, albumin, CK8 and CK19). These differentiated ADSCs were transplanted intra-hepatically in CCl4-induced liver fibrosis model. After one month of transplantation, fibrosis and liver functions (alkaline phosphatase, ALAT and bilirubin) showed marked improvement in acute injury group. Elevated expression of hepatic (AFP, albumin, CK 18 and HNF4a) and pro survival markers (PCNA and VEGF) and improvement in liver architecture as deduced from results of alpha smooth muscle actin, Sirius red and Masson's trichome staining was observed.

Abstract
H19 is a long non-coding RNA regulated by genomic imprinting through methylation at the locus between H19 and IGF2. H19 is important in normal liver development, controlling proliferation and impacting genes involved in an important network controlling fetal development. H19 also plays a major role in disease progression, particularly in hepatocellular carcinoma. H19 participates in the epigenetic regulation of many processes impacting diseases, such as activating the miR-200 pathway by histone acetylation to inhibit the epithelial-mesenchymal transition to suppress tumor metastasis. Furthermore, H19's normal regulation is disturbed in diseases, such as hepatocellular carcinoma. In this disease, aberrant epigenetic maintenance results in biallelic expression of IGF2, leading to uncontrolled cellular proliferation. This review aims to further research utilizing H19 for drug discovery and the treatment of liver diseases by focusing on both the epigenetic regulation of H19 and how H19 regulates normal liver functions and diseases, particularly by epigenetic mechanisms.

Abstract
To provide fundamental insights into the mechanism of Hepatitis C virus (HCV), we conduct the present study to improve further understanding of the interaction between HCV and cytokines. Two hundred one patients were enrolled in this study. Seventy-eight patients matching the study group in terms of age and gender with negative serology for hepatitis viruses, HIV virus, and with liver enzyme levels within normal range were selected as the control group. Patients were diagnosed with positive hepatitis C by detection of positive HCV antibodies in serum. Interferon-gamma (IFN-γ) and interleukin (IL)-10 were measured in positive and negative patients. Also liver functions (alanine aminotransferase [ALT], aspartate aminotransferase [AST], gamma glutamyl transferase [GGT], alkaline phosphatase [ALP], urea, total protein, albumin, total and direct bilirubin) were also measured. Our results indicated significant elevation in IL-10 and IFN-γ in positive hepatitis C patients. These elevations were accompanied by significant elevation in liver function biomarkers with significant regression in albumin and total protein content. Furthermore, IFN-γ significantly increased immune response of cellular immunity. IL-10 significantly decreased immune response of cellular immunity by inhibiting IFN-γ and other production of Th. Liver function levels can be used as a marker for HCV. The findings from our study recommend IL-10 pathway in HCV infection and use IFNs to increase immune response for viral hepatitis.

Abstract
BACKGROUND Although raspberry seed oil (RO) is rich in essential fatty acids, there is a lack of experiments assessing benefits of its consumption. OBJECTIVE We investigated the effects of dietary supplementation with RO on healthy rats and rats with low-grade systemic inflammation, liver disorders, and dyslipidemia induced by a high-fat/low-fiber (HF/LF) diet. METHODS Thirty-two rats were allocated into 4 groups of 8 rats each and fed for 8 wk a control (C; 7% lard and 5% cellulose) or HF/LF (21% lard and 2% cellulose) diet or modifications of these diets in which 7% RO replaced all (C+RO group) or a proportion of (HF/LF+RO group) the lard. Effects of diet and RO and their interaction on bacterial activity and metabolite formations in the distal intestine, liver fat and glutathione concentration, plasma lipid profile, transaminase activities, and plasma concentrations of C-reactive protein (CRP) and tumor necrosis factor α (TNF-α) were tested. RESULTS Dietary RO decreased plasma alanine and aspartate transaminase activities (43.4 and 157 vs. 25.6 and 115 U/L, respectively; P < 0.05 and P < 0.005) and plasma TNF-α and triglyceride concentrations (132 pg/mL and 2.07 mmol/L vs. 86.5 pg/mL and 0.99 mmol/L, respectively; P < 0.05). In livers of the C+RO group, the fat concentration was decreased, whereas the glutathione to glutathione disulfide ratio was increased compared with the C group (30.1% and 6.20 μmol/g vs. 23.3% and 7.25 μmol/g, respectively; P ≤ 0.05); however, those differences were not observed between the HF/LF groups (P-interaction < 0.05). In the HF/LF+RO group, the plasma CRP concentration was lower than in the HF/LF group (88.1 vs. 765 pg/mL; P ≤ 0.05) and similar to that in the C and C+RO groups (158 and 128 pg/mL, respectively). CONCLUSION Dietary RO improves plasma lipid profile and liver functions and reduces low-grade systemic inflammation in rats; however, the extent of these beneficial effects is partly dependent on the diet type.

Abstract
BACKGROUND Hydrocarbons which are among the major components of petroleum products are considered toxic and have been implicated in a number of human diseases. Tanker drivers are continuously exposed to hydrocarbons by inhalation and most of these drivers do not use protective devices to prevent inhalation of petroleum products; nor do they visit hospital regularly for routine check-up. OBJECTIVE In view of this occupational hazard, we investigated the haematological, renal and hepatic functions of workers of petroleum tankers drivers in Lagos, Nigeria. METHOD Twenty-five tanker drivers' and fifteen control subjects were randomly selected based on the selection criteria of not smoking and working for minimum of 5 years as petroleum tanker driver. The liver, renal and haematological parameters were analyzed using automated clinical and haematological analyzers while the lipid peroxidation and antioxidant level tests were assayed using standard methods. RESULTS There were significant (p ≤ 0.05) increases in the levels of serum alanine amino transferase (31.14±13.72; 22.38±9.89), albumin (42.50±4.69; 45.36±1.74) and alkaline phosphatase (84.04±21.89; 62.04±23.33) of petroleum tanker drivers compared with the controls. A significant (p≤0.05) increase in the levels of creatinine, urea and white blood cells of the tanker drivers, compared with the controls, were also obtained. CONCLUSION The results have enormous health implications of continuous exposure to petroleum products reflected hepatic and renal damage of petroleum tanker drivers. Therefore, there is need for this group of workers to be sensitized on the importance of protective devises, regular medical checkup and management.

Abstract
OBJECTIVE To identify metabolic changes associated with early spontaneous preterm birth (PTB; <34 weeks) and term births, using high-throughput metabolomics of amniotic fluid (AF) in African American population. METHOD In this study, AF samples retrieved from spontaneous PTB (<34 weeks [n = 25]) and normal term birth (n = 25) by transvaginal amniocentesis at the time of labor prior to delivery were subjected to metabolomics analysis. Equal volumes of samples were subjected to a standard solvent extraction method and analyzed using gas chromatography/mass spectrometry (MS) and liquid chromatography/MS/MS. Biochemicals were identified through matching of ion features to a library of biochemical standards. After log transformation and imputation of minimum observed values for each compound, t test, correlation tests, and false discovery rate corrections were used to identify differentially regulated metabolites. Data were controlled for clinical/demographic variables and medication during pregnancy. RESULTS Of 348 metabolites measured in AF samples, 121 metabolites had a gestational age effect and 116 differed significantly between PTB and term births. A majority of significantly altered metabolites could be classified into 3 categories, namely, (1) liver function, (2) fatty acid and coenzyme A (CoA) metabolism, and (3) histidine metabolism. The signature of altered liver function was apparent in many cytochrome P450-related pathways including bile acids, steroids, xanthines, heme, and phase II detoxification of xenobiotics with the largest fold change seen with pantothenol, a CoA synthesis inhibitor that was 8-fold more abundant in PTB. CONCLUSION Global metabolic profiling of AF revealed alteration in hepatic metabolites involving xenobiotic detoxification and CoA metabolism in PTB. Maternal and/or fetal hepatic function differences may be developmentally related and its contribution PTB as a cause or effect of PTB is still unclear.

Abstract
UNLABELLED The aim of the present investigation was to study the effects of olive oil (OO), corn oil (CO), and flaxseed oil (FO), with or without supplementation of vitamins E and C, on food intake, body weight gain %, liver weight to body weight %, total lipids, liver functions, and liver histology in male rats intoxicated with carbon tetrachloride (CCl(4)). Forty-two rats were divided into two main groups. The first main group was fed on basal diet (BD) as a negative control group (NC). The second main group received subcutaneous injections of CCl(4) in paraffin oil (50% v/v 2 ml/kg) twice a week to induce chronic damage in the liver. The group was then divided into six subgroups, three of which were fed on 4% unsupplemented oils (CO, FO, and OO) as positive control for the three oils used. The rest of the groups were fed on 4% of the same oils supplemented with vitamins E and C. The results of the flaxseed oil rat group indicate that supplementing vitamin E and C led to a significant reduction in the mean values of total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), and liver alanine amino transferase enzyme (ALT). Moreover, it caused an increase of the mean value of high-density lipoprotein cholesterol (HDL-C) as compared to the negative control group (NC). The olive oil group supplemented with the same vitamins showed a significant decrease in the mean value of serum TC and significant (P<0.05) increase in the mean value of serum HDL-C as compared to NC. The results of the corn oil group supplemented with vitamins showed a significant increase in the mean value of serum HDL-C as compared to the negative control group. The histology results confirmed that the group hepatically injured with CCl(4) treatment and fed on supplemented FO or OO showed apparently normal hepatocytes. CONCLUSION The most effective treatment was observed with oils supplemented with vitamins E and C. Hierarchically FO achieved the best results compared to other additives, followed by OO and finally CO showing the least effective treatment among the observed groups.

Abstract
Depo-medroxy progesterone acetate (DMPA, Depo-Provera) is used in more than 80 countries as a long-acting contraceptive administered as a single intramuscular(i.m) injection of 150 mg/3 months. The present study was set up to investigate the effects of DMPA on 80 average Egyptian women classified into four groups comprising those using the drug for one, two, three and four years, respectively, compared to a control group (N = 20) of married non-hormonally - treated women of similar ages. The drug showed a transient significant elevation of alanine aminotransferase activity (ALT)without an apparent effect on other liver indices, namely total bilirubin (T.Bil) level,aspartate aminotransferase (AST) and alkaline phosphatase (ALP) activities. Only the low density/high density lipoproteins cholesterol ratio (LDLC/HDLC) was gradually and non-significantly (ns) increased in comparison to control group, however, neither total cholesterol (TC) nor triglycerides (TG) were affected by the drug. The lipid peroxide product malondialdehyde (MDA) was significantly elevated in an gradual manner with a corresponding decrease in reduced glutathione (GSH), without any change in blood nitric oxide (NO) levels. It can be concluded that DMPA may be considered as a safe contraceptive medication for the studied group of women, but that special care should be exercised for cardiovascular, hepatic and other patients more sensitive to the harmful effects of free radicals. Alternatively, supportive medications are advisable for each exposed case to secure against the possible irreversible adverse effects of the drug by continuous use. In addition, annual re-evaluation is much more advisable despite the proven safety of the drug.
