Studies on Smilax perfoliata and Breynia retusa against Experimentally Induced Cancer in Swiss Albino Mice

The anticancer effect of methanolic extracts of Smilax perfoliata roots and Breynia retusa bark against Ehrlich ascites carcinoma (EAC) was investigated in the present study. The procured plant material was subjected to soxhlet extraction using methanol. Albino mice were divided into 7 groups of 6 mice (n = 6) in each group. Group I served as a control for about 14 days, and groups II to VII were administered EAC cells and the standard drug doxorubicin (0.3, i. p.) and test extracts at two doses 200 & 400 mg/kg daily. On last day of the experiment, mice were sacrificed for antitumor activity, tumor volume, cell viability, mean survival time and life span. Hematological and biochemical parameters were estimated. Liver sections were prepared and examined for histological changes. The antitumor effect of both the test extracts was dose-dependent. The volume of the tumor and cell viability were significantly reduced (**p < 0.001), whereas the mean survival time and life span were raised in a significant manner (**p < 0.001). The hematological parameters such as hemoglobin content, RBC, monocytes and lymphocytes were raised while WBC and neutrophils were reduced significantly (**p < 0.001) and the levels of serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), alkaline phosphatase (SALP), and bilirubin were reduced significantly after the treatment with the test drugs. Histopathological study revealed the restoration of the structure of the liver in the post-treatment animals. It was concluded that the methanolic extract of S. perfoliata roots and B. retusa bark exhibited antitumor activity, which might be due to the presence of alkaloids, glycosides, flavonoids, phytosterols, phenolic compounds phytosterols, carbohydrates and tannins. Further investigation of bioactive compounds is needed to confirm the anticancer properties thoroughly.

Comprehensive Study of Ehretia laevis in Treatment of Diabetes and Related Complications

Diabetes mellitus appears to be a significant health issue globally, impacting millions of individuals and imposing an economic strain on healthcare systems all over the world. The pursuit of effective and safe alternative therapies has led researchers to investigate therapeutic plants with probable antidiabetic activity. This article highlights a comprehensive study investigating the therapeutic potential of Ehretia laevis in controlling of diabetes and associated complications in rats. The phytochemical investigation of E. laevis extracts observed phytoconstituents like flavonoids, phenolics, and triterpenoids. These phytoconstituents are known to possess antidiabetic properties. By injecting 60 mg/kg of STZ intraperitoneally once, rats were induced to develop diabetes. According to the experimental study, blood glucose levels were significantly reduced from 270 to 118 mg/dl after administering 200 and 400 mg/kg of aqueous and methanolic E. laevis extracts. Further evaluations on serum glutamic oxaloacetic transaminase (SGOT) and serum glutamate pyruvate transaminase (SGPT) revealed a significant reduction in their values, highlighting the control of liver complications. A lowering of serum urea and creatinine levels served to assess kidney-related complications. This comprehensive study sheds light on the potential of E. laevis in the treatment of diabetes and paves a path for the development of formulations, however, further mechanistic evaluation could be explored.

Effects of Feeding Glucogenic and Lipogenic Diets on Performance and Blood Parameters of Transition Dairy Cows and Their Calves

Introduction: Several studies have explored the impact of diet type on energy sources. The current study aimed to evaluate the impact of feeding glucogenic versus lipogenic diets to Holstein dairy cows during the close-up period on cows' performances and their calves' growth parameters. Materials and methods: Twenty-four Holstein dairy cows with an average parity of 3 selected for the study, starting 21 days before expected calving. The cows were divided into three groups based on a randomized complete block design including a Control diet (glucogenic diet, Glu), a low lipogenic diet (Llip) with 25% barley grain replaced by beet pulp, and a high lipogenic diet (Hlip) with 50% barley grain replaced by beet pulp. Daily recording of dry matter intake (DMI) was conducted, with blood samples collected on the day of parturition in cows and days 1, 2, 7, and 21 of calves age. In dairy cows, both the quality and quantity of colostrum were determined. Additionally, performance variables including feed intake, average daily gain, and skeletal parameters such as shoulder height, Hip height, and body length were measured. Blood parameters, such as glucose, triglyceride, and concentrations of certain liver enzymes, including alkaline phosphatase (ALP), serum glutamic-pyruvic transaminase (SGPT), and serum glutamate oxaloacetate transaminase (SGOT) were recorded in calves. Results: The increase of beet pulp in the prepartum diet led to a significant increase in DMI. Colostrum yield and constituents (protein, lactose, and solids nonfat percentage) decreased with an increase in beet pulp level and the differences between Glu and Hlip were significant. Performance parameters of the calves were similar across all treatments, except skeletal growth. Calves that were fed the Hlip diet showed a lower shoulder height compared to those fed the Glu diet. Blood glucose was significantly higher in cows and their offspring that were fed Llip diets compared to other groups. The concentration of liver enzymes, including ALP, SGPT, and SGOT was not affected by treatments. Conclusion: Substituting barley grain with beet pulp as a lipogenic component may enhance dry matter intake in periparturient dairy cows. However, it did not show a notable impact on offspring performance.

The use of belimumab on patients with both systemic lupus erythematosus and immune thrombocytopenia: A retrospective cohort study.

The objective of this study is to provide a description of a group of retrospective cohort outcomes in patients with systemic lupus erythematosus (SLE) complicated with immune thrombocytopenia (ITP) receiving belimumab. This study reports on the treatment of 10 female patients (mean age 34.3 ± 14.0years, mean weight 58.7 ± 18.2kg) with both SLE and ITP who received belimumab in addition to basic drug therapy. The belimumab treatment regimen consisted of a dosage of 10mg/kg, with an initial infusion every 2weeks for the first 3 doses, followed by an infusion every 4weeks. Ten patients were included in the study. The overall response rate of thrombocytopenia was 90% after treatment. The parameters such as platelet count, lymphocyte count, erythrocyte count, hemoglobin, dsDNA, C3, and C4 were significantly improved (p < .05). The SLE Disease Activity Index (SLEDAI), British Islet lupus Assessment Group 2004 (BILAG-2004), and Physician Global assessment (PGA) scores were significantly decreased (p < .05). There were no significant differences in glutamic pyruvic transaminase (ALT), glutamic oxaloacetic transaminase (AST), and serum creatinine (Scr) before and after treatment (p > .05). Belimumab shows promising clinical outcomes in the treatment on patients with both SLE and ITP. Further studies are needed to validate these findings in larger patient populations and compare the efficacy of belimumab with other treatments for SLE complicated with ITP. Long-term response rates and adverse events associated with belimumab treatment also warrant further investigation.

Hepatoprotective Effect of Allium ochotense Extracts on Chronic Alcohol-Induced Fatty Liver and Hepatic Inflammation in C57BL/6 Mice.

This study was performed to investigate the protective effects of Allium ochotense on fatty liver and hepatitis in chronic alcohol-induced hepatotoxicity. The physiological compounds of a mixture of aqueous and 60% ethanol (2:8, w/w) extracts of A. ochotense (EA) were identified as kestose, raffinose, kaempferol and quercetin glucoside, and kaempferol di-glucoside by UPLC Q-TOF MSE. The EA regulated the levels of lipid metabolism-related biomarkers such as total cholesterol, triglyceride, low-density lipoprotein (LDL), and high-density lipoprotein (HDL)-cholesterol in serum. Also, EA ameliorated the levels of liver toxicity-related biomarkers such as glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), and total bilirubin in serum. EA improved the antioxidant system by reducing malondialdehyde contents and increasing superoxide dismutase (SOD) levels and reduced glutathione content. EA improved the alcohol metabolizing enzymes such as alcohol dehydrogenase, acetaldehyde dehydrogenase, and cytochrome P450 2E1 (CYP2E1). Treatment with EA alleviated lipid accumulation-related protein expression by improving phosphorylation of AMP-activated protein kinase (p-AMPK) expression levels. Especially, EA reduced inflammatory response by regulating the toll-like receptor-4/nuclear factor kappa-light-chain-enhancer of activated B cells (TLR-4/NF-κB) signaling pathway. EA showed an anti-apoptotic effect by regulating the expression levels of B-cell lymphoma 2 (BCl-2), BCl-2-associated X protein (BAX), and caspase 3. Treatment with EA also ameliorated liver fibrosis via inhibition of transforming growth factor-beta 1/suppressor of mothers against decapentaplegic (TGF-β1/Smad) pathway and alpha-smooth muscle actin (α-SMA). Therefore, these results suggest that EA might be a potential prophylactic agent for the treatment of alcoholic liver disease.

Nonalcoholic Fatty Liver Disease: Changes in Gut Microbiota and Blood Lipids.

The global prevalence of nonalcoholic fatty liver disease (NAFLD) is 25%. This study aimed to explore differences in the gut microbial community and blood lipids between normal livers and those affected by NAFLD using 16S ribosomal deoxyribonucleic acid sequencing. Gut microbiome profiles of 40 NAFLD and 20 non-NAFLD controls were analyzed. Information about four blood lipids and 13 other clinical features was collected. Patients were divided into three groups by ultrasound and FibroScan, those with a normal liver, mild FL (FL1), and moderate-to-severe FL (FL2). FL1 and FL2 patients were divided into two groups, those with either hyperlipidemia or non-hyperlipidemia based on their blood lipids. Potential keystone species within the groups were identified using univariate analysis and a specificity-occupancy plot. Significant difference in biochemical parameters ion NAFLD patients and healthy individuals were identified by detrended correspondence analysis and canonical correspondence analysis. Decreased gut bacterial diversity was found in patients with NAFLD. Firmicutes/Bacteroidetes decreased as NAFLD progressed. Faecalibacterium and Ruminococcus 2 were the most representative fatty-related bacteria. Glutamate pyruvic transaminase, aspartate aminotransferase, and white blood cell count were selected as the most significant biochemical indexes. Calculation of areas under the curve identified two microbiomes combined with the three biochemical indexes that identified normal liver and FL2 very well but performed poorly in diagnosing FL1. Faecalibacterium and Ruminococcus 2, combined with glutamate pyruvic transaminase, aspartate aminotransferase, and white blood cell count distinguished NAFLD. We speculate that regulating the health of gut microbiota may release NAFLD, in addition to providing new targets for clinicians to treat NAFLD.

Mulberry leaf and konjac flour compound dietary fiber improves digestion and metabolism in elderly mice with high-fish-protein diet by regulating gut microbiota structure and intestinal tissue repair

Ensuring sufficient protein intake, efficient digestion, and optimal absorption are crucial for the elderly. This study aims to investigate the potential of a compound dietary fiber, consisting of mulberry leaf and konjac flour (CMK), to enhance the digestion and absorption of a high-fish-protein diet in elderly mice. Results showed that CMK effectively reduced the number of unique peptide segments, generated short-chain fatty acids (SCFA) in feces, improved the content of glutamic pyruvic transaminase (GPT), glutamic oxaloacetic transaminase (GOT), amino acid, and urea nitrogen in serum, activated the contents of pepsin, trypsin, and erepsin, and enhanced the expression of glutamate dehydrogenase (GDH), peptide transporter 1 (PepT1), and aminopeptidase N (APN). Furthermore, CMK demonstrated its ability to decrease the levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-10 (IL-10), lipopolysaccharide (LPS), and lipopolysaccharide binding protein (LBP), while increase the abundance of beneficial bacteria, such as Lactobacillus and Blautia. In conclusion, CMK proved effective in enhancing the digestion and metabolism of protein in elderly mice through the regulation of gut microbiota structure and intestinal tissue repair.

Promising role of traditional Indian Ayurvedic medicine in treatment, management and better clinical outcomes of COVID-19 patients: a retrospective study

IntroductionThe Coronavirus disease (COVID-19) has negatively impacted the lives of people globally. To date, no specific treatment has emerged to combat the disease. Hence, there is an urge for immediate therapy against infections like COVID-19 through the inclusion of various traditional medicines including Ayurveda. MethodsThis retrospective study was performed on 300 patients who were treated using the Holistic Ayurveda protocol at the COVID Health Care (CHC) centre. Out of 300 patients, 258 who took the AYURAKSHA Kit regularly along with the other Ayurvedic medicines for treatment were selected for this study. Demographic distribution, viral clearance, and haematological parameters of COVID-19 patients were analysed. ResultsThe maximum number of COVID-19 positive cases (31.4%) were found in the age group 20–29 years whereas the age group 40–49 years (11.52 days) and ≥ 60 years (11.5 days) took the maximum time (P = 0.035) for viral clearance. The haematological investigations showed that the Ayurveda treatment maintained the admitted patients' blood profile and coagulation profile. Strikingly, liver and kidney profiles improved post-treatment as Serum Glutamic-Oxaloacetic Transaminase (P = 0.000), Serum Glutamic Pyruvic Transaminase (P = 0.000), Urea (P = 0.000), and Creatinine (P = 0.002) levels were significantly reduced. Likewise, a significant reduction in inflammation markers like C-reactive Protein (P = 0.000), Erythrocyte Sedimentation Rate (P = 0.003), and serum Ferritin (P = 0.000) was also observed. No adverse treatment effects were observed during follow-up of the patients. ConclusionThe above outcomes showed that the Holistic Ayurveda Protocol in treating COVID-19 patients is safe, acceptable and effective. Thus, suggesting the possible integration of Ayurvedic treatment in combating such deadly diseases.

Hypoxia leads to gill endoplasmic reticulum stress and disruption of mitochondrial homeostasis in grass carp (Ctenopharyngodon idella): Mitigation effect of thiamine

Hypoxia in water environment is one of the important problems faced by intensive aquaculture. Under hypoxia stress, the effects of dietary thiamine were investigated on grass carp gill tissue damage and their mechanisms. Six thiamine diets with different thiamine levels (0.22, 0.43, 0.73, 1.03, 1.33 and 1.63 mg/kg) were fed grass carp (Ctenopharyngodon idella) for 63 days. Then, 96-hour hypoxia stress test was conducted. This study described that thiamine enhanced the growth performance of adult grass carp and ameliorated nutritional status of thiamine (pyruvic acid, glucose, lactic acid and transketolase). Additionally, thiamine alleviated the deterioration of blood parameters [glutamic oxalacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), glucose, cortisol, lactic dehydrogenase (LDH), erythrocyte fragility, and red blood cell count (RBC count)] caused by hypoxia stress, and reduced reactive oxygen species (ROS) content and oxidative damage to the gills. In addition, thiamine alleviated endoplasmic reticulum stress in the gills, which may be related to its inhibition of RNA-dependent protein kinase-like ER kinase (PERK)/eukaryotic translation initiation factor-2α (eIF2α)/activating transcription factor4 (ATF4), inositol-requiring enzyme 1 (IRE1)/X-Box binding protein 1 (XBP1) and activating transcription factor 6 (ATF6) pathways. Furthermore, thiamine maintaining mitochondrial dynamics balance was probably related to promoting mitochondrial fusion and inhibiting mitochondrial fission, and inhibiting mitophagy may involve PTEN induced putative kinase 1 (PINK1)/Parkin-dependent pathway and hypoxia-inducible factor (HIF)-Bcl-2 adenovirus E1B 19 kDa interacting protein 3 (BNIP3) pathway. In summary, thiamine alleviated hypoxia stress in fish gills, which may be related to reducing endoplasmic reticulum stress, regulating mitochondrial dynamics balance and reducing mitophagy. The thiamine requirement for optimum growth [percent weight gain (PWG)] of adult grass carp was estimated to be 0.81 mg/kg diet. Based on the index of anti-hypoxia stress (ROS content in gill), the thiamine requirement for adult grass carp was estimated to be 1.32 mg/kg diet.

Rujifang inhibits triple-negative breast cancer growth via the PI3K/AKT pathway

Ethnopharmacological relevanceRujifang (RJF) constitutes a traditional Chinese medicinal compound extensively employed in the management of triple-negative breast cancer (TNBC). However, information regarding its potential active ingredients, antitumor effects, safety, and mechanism of action remains unreported. Aim of the studyTo investigate the efficacy and safety of RJF in the context of TNBC. Materials and methodsWe employed the ultra high-performance liquid chromatography-electrospray four-pole time-of-flight mass spectrometry technique (UPLC/Q-TOF-MS/MS) to scrutinize the chemical constituents of RJF. Subcutaneously transplanted tumor models were utilized to assess the impact of RJF on TNBC in vivo. Thirty female BLAB/c mice were randomly divided into five groups: the model group, cyclophosphamide group, and RJF high-dose, medium-dose, and low-dose groups. A total of 1 × 106 4T1 cells were subcutaneously injected into the right shoulder of mice, and they were administered treatments for a span of 28 days. We conducted evaluations on blood parameters, encompassing white blood cell count (WBC), red blood cell count (RBC), hemoglobin (HGB), platelet count (PLT), neutrophils, lymphocytes, and monocytes, as well as hepatorenal indicators including alkaline phosphatase (ALP), glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT), albumin, and creatinine (CRE) to gauge the safety of RJF. Ki67 and TUNEL were detected via immunohistochemistry and immunofluorescence, respectively. We prepared RJF drug-containing serum for TNBC cell lines and assessed the in vitro inhibitory effect of RJF on tumor cell growth through the CCK8 assay and cell cycle analysis. RT-PCR was employed to detect the mRNA expression of cyclin-dependent kinase and cyclin-dependent kinase inhibitors in tumor tissues, and Western blot was carried out to ascertain the expression of cyclin and pathway-related proteins. Results100 compounds were identified in RJF, which consisted of 3 flavonoids, 24 glycosides, 18 alkaloids, 3 amino acids, 8 phenylpropanoids, 6 terpenes, 20 organic acids, and 18 other compounds. In animal experiments, both CTX and RJF exhibited substantial antitumor effects. RJF led to an increase in the number of neutrophils in peripheral blood, with no significant impact on other hematological indices. In contrast, CTX reduced red blood cell count, hemoglobin levels, and white blood cell count, while increasing platelet count. RJF exhibited no discernible influence on hepatorenal function, whereas Cyclophosphamide (CTX) decreased ALP, GOT, and GPT levels. Both CTX and RJF reduced the expression of Ki67 and heightened the occurrence of apoptosis in tumor tissue. RJF drug-containing serum hindered the viability of 4T1 and MD-MBA-231 cells in a time and concentration-dependent manner. In cell cycle experiments, RJF diminished the proportion of G2 phase cells and arrested the cell cycle at the S phase. RT-PCR analysis indicated that RJF down-regulated the mRNA expression of CDK2 and CDK4, while up-regulating that of P21 and P27 in tumor tissue. The trends in CDKs and CDKIs protein expression mirrored those of mRNA expression. Moreover, the PI3K/AKT pathway displayed downregulation in the tumor tissue of mice treated with RJF. ConclusionRJF demonstrates effectiveness and safety in the context of TNBC. It exerts anti-tumor effects by arresting the cell cycle at the S phase through the PI3K-AKT pathway.

Redefining the hepatoprotective potential of Javanese turmeric (Curcuma xanthorrhiza) Kombucha towards the diethylnitrosamine-induced hepatotoxicity of mice

PurposeThis research intended the utilization of Javanese turmeric (0.4% w/v) as a kombucha substrate and analysis of its hepatoprotective activity, in comparison against nonfermented Javanese turmeric beverage (JTB) and black tea kombucha.Design/methodology/approachForty-two healthy male Balb/c mice (two- to three-week-old, 20–30 g) were divided into six groups with seven replicates each. The treatments were normal diet, normal diet + Javanese turmeric kombucha (JTK), normal diet + diethylnitrosamine (DEN), DEN + JTB, DEN + JTK, DEN + black tea kombucha. Kombuchas and JTB were given at 0.3 mL/20 g BW/d. DEN was induced intraperitoneally at a dose of 100 mg/kg. Observed biomarkers were blood serum glutamate pyruvate transaminase (SGPT) and serum glutamate oxaloacetate transaminase (SGOT) activity, serum malonaldehyde (MDA), as well as liver histology. Data were analyzed using analysis of variance.FindingsAmong DEN-induced groups, JTK significantly (p < 0.05) diminished the level of blood SGPT, SGOT and serum MDA. JTK also had lower blood SGPT (8.604 ± 2.195 U/L) and serum MDA levels (2.884 ± 0.083 nM/mL) compared to the normal group (8.604 ± 2.195 U/L and 5.050 ± 0.998 nM/mL, respectively). JTK also produced the least damaged liver-cell numbers.Originality/valueJTK demonstrated better hepatoprotective activity compared to JTB.

Dietary supplementation of prebiotic yeast Saccharomyces cerevisiae cell wall promotes growth performance and intestinal health in broiler chickens challenged with Clostridium perfringens

ABSTRACT 1. This study evaluated the effectiveness of yeast (S accharomyces cerevisiae) cell wall (YCW) supplementation on the growth performance, carcase characteristics, serum biomarkers, liver function, ileal histology and microbiota of broiler chickens challenged with Clostridium perfringens (C. perfringens). 2. In a 35-d trial, 240 chicks aged 1-d-old were randomly assigned to one of four treatment groups, each with 10 replicates: control (CON) with no challenge or additives, challenged with C. perfringens (CHAL), CHAL and supplemented with YCW at either 0.25 g/kg (YCW0.25) or 0.5 g/kg (YCW0.5). 3. In comparison to CON, the CHAL birds had reduced growth performance, survival rate, dressing percentage, breast meat yield, levels of total protein (TP), globulin (GLO), glucose (GLU), total antioxidant capacity (T-AOC) and total superoxide dismutase (T-SOD), as well as a decreased Lactobacillus population (P < 0.01). Additionally, this group showed elevated levels of glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), and C. perfringens count (P < 0.01). Compared to CHAL, the YCW0.25 or YCW0.5 groups had improved growth performance, survival rate, dressing percentage, breast meat yield, levels of TP, GLO, GLU, and T-AOC, as well as the activities of T-SOD, GOT, and GPT, villus height, villus surface area, villus height to crypt depth ratio, and the populations of both Lactobacillus and C. perfringens; (P < 0.01). 4. The data suggested that YCW supplementation at either 0.25 or 0.50 g/kg can restore the growth performance of broiler chickens during a C. perfringens challenge.

Exploring Therapeutic Potential of Pleurotus ostreatus and Agaricus bisporus Mushrooms against Hyperlipidemia and Oxidative Stress Using Animal Model.

The mushrooms oyster (Pleurotus ostreatus) and white button (Agaricus bisporus) contain bioactive compounds that have potential beneficial effects on hypercholesterolemia and cardiovascular diseases. In this study, hypolipidemic and antioxidative potential of these mushrooms' extract were explored using hypercholesterolemic (HC) rats as animal model. For the study, 56 adult rats were divided into seven groups, i.e., G1 (negative control), G2 (positive control group), G3 (HC rats with statin drug orally), G4 and G5 (HC rats @ 100 and 200 mg/kg body weight (BW) dose of oyster mushroom extracts), and G6 and G7 (HC rats @ 100 and 200 mg/kg BW dose of white button mushroom extracts). The hypercholesterolemia was induced experimentally in fasted rats through a high-fat diet along with injection of triton WR-1339. After 48 h, the treatment groups were given extract for 28 days along with standard diet. At the trial termination, we analyzed the blood sugar levels, antioxidant parameters, lipid profile, and renal function, as well as conducting liver function tests of the rats. The results indicated that positive control group rats exhibited increased levels of total cholesterol (TC), triglycerides (TG), low-density level (LDL), and very-low-density level (vLDL) by 19%, 37%, 52%, and 32%, respectively, and 53% decrease in HDL, whereas treatment groups that received 200 mg oyster and white button mushroom extracts reported 15%, 34%, 22% reduction in TC, TG, vLDL, respectively, and 22% improvement in HDL level. The enzyme profiles of different groups showed non-significant differences, although both mushroom extracts provision reduced glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) levels. Overall, the results indicated that mushroom extracts were helpful in maintaining oxidative stress and have the potential to improve dyslipidemia in the tested rat animal model.

Effect of Zinc Oxide Nanoparticles on Liver Functions in Albino Mice.

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. 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. 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.

Hypoglycemic Activity and Safety Assessment of Pediococcus acidilactici Strain DNH16 in Experimental Type 2 Diabetes Mellitus Rats Induced with Streptozotocin

BACKGROUND: Type 2 diabetes mellitus (T2DM) cases tend to rise throughout the year in all parts of the world. The α-glucosidase inhibitors are frequently used to both prevent and treat T2DM. This α-glucosidase inhibitor activity is seen in some probiotic species, and a certain strain of Pediococcus acidilactici exhibits promising characteristics as an α-glucosidase inhibitor. This study was conducted to assess the hypoglycemic activity and safety of P. acidilactici strain DNH16 (PADNH16) in experimental rats with T2DM induced by streptozotocin.METHODS: The experiment was conducted in vivo using Wistar rats. Acarbose was employed as a positive control, and Lactobacillus casei was used as a comparative. For 24 days, post-prandial blood glucose levels were assessed every 3 days, followed by serum biochemical levels measurement of liver, kidney, and lipid profiles. The pancreas was histopathologically examined utilizing the Hematoxyline-Eosin staining procedure.RESULTS: Administration of PADNH16 to T2DM rats lowered post-prandial blood glucose levels and gave hypoglycemic benefits comparable to acarbose and commercial probiotics. PADNH16 dosing did not affect serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT), urea, or creatinine levels, showing that PADNH16 was not hazardous to liver or kidney function. The lipid profile assessment revealed that the values, including high-density lipoprotein (HDL), low-density lipoprotein (LDL), and triglycerides, were comparable to the control group. The pancreatic histopathology revealed that injection of PADNH16 caused no alterations to pancreatic β cells.CONCLUSION: P. acidilactici isolate DNH16 has a hypoglycemic effect on T2DM rats, but does not affect liver function enzymes, kidneys, lipid profiles and does not provide significant changes in pancreatic β cells.KEYWORDS: diabetes mellitus, inhibitor α-glucosidase, Pediococcus acidilactici strain DNH16

Antidiabetic activity of methanolic extract of Hibiscus sabdariffa Linn. fruit in alloxan-induced Swiss albino diabetic mice

Abstract The majority of natural diabetic medications come from fruits and vegetables. These natural medications help protect humans from negative impacts of chemical antidiabetics by scavenging free radicals. The present study aimed to explore the antioxidant and antidiabetic properties of methanolic extract of fruits of Hibiscus sabdariffa Linn. (MEHSF) in alloxan-induced Swiss albino diabetic mice. The dried coarse powder of Hibiscus sabdariffa Linn. fruits was subjected to methanol extraction. The antidiabetic activity was determined by using alloxan-induced (80 mg/kg body weight) diabetic mice. Following a 15-day treatment period, serum biochemical parameters including total cholesterol (TC), triglyceride (TAG), LDL-cholesterol (LDL), HDL-cholesterol (HDL), serum glutamic pyruvic transaminase (SGPT), and serum glutamic-oxaloacetic transaminase (SGOT) enzymes were estimated. The antioxidant activity was evaluated through a DPPH and ABTS free radical scavenging assay. Total phenolic content and total flavonoid content were assessed using established methods. MESHF, containing polyphenolic and flavonoid compounds, exhibited antioxidant properties. A 100 and 200 mg/kg significantly (p &lt; 0.05) lowered the blood glucose levels and improved biochemical parameters such as TC, TAG, LDL, and HDL in diabetic mice. Further, MESHF significantly (p &lt; 0.05) reduced the activity of the SGPT and SGOT in diabetic mice compared to untreated diabetic mice. These results suggest that MEHSF with promising antioxidant and antidiabetic potentials can be considered to be a probable new resource of the antidiabetic agent.

Aesthetic Radiofrequency Associated with Rosmarinus officinalis Supplementation is Safe and Reduces Oxidative Stress in Women: Randomized, and Double-Blind Clinical Trial.

The objective were to evaluate the effects of supplementation of standardized dry extract of Rosmarinus officinalis (RO) and the application of aesthetic radiofrequency on the oxidative stress markers catalase (CAT), superoxide dismutase (SOD), non-protein thiols (NP-SH), and thiobarbituric acid reactive species (TBARS) and the biochemical markers triglycerides, total cholesterol, high density lipoprotein (HDL) cholesterol, glutamic-oxaloacetic transaminase (TGO/AST), pyruvic-glutamic transaminase (TGP/ALT), gamma glutamyl transpeptidase (gamma-GT), and creatinine. This study included 32 women received the aesthetic therapy to reduce localized fat. They were divided into the control group (n = 8) receiving placebo capsules and the intervention group (n = 24) subdivided into Group A, B, and C, each with eight members receiving supplementation with 100, 500, and 1000 mg/day of standardized dry extract of RO, respectively. The Universal Trial Number (UTN) - U1111-1274-6255. Supplementation with RO (500 mg/day) demonstrated a reduction in oxidative stress (quantified with through a significant increase in NP-SH and a reduction in SOD and CAT enzymes). The radiofrequency aesthetic treatment did not promote an increase in oxidative stress; however, it caused significant changes in total cholesterol, HDL cholesterol, and creatinine. RO is a plant with antioxidant effects and its oral consumption is safe in selected women subjects in hepatic and renal markers.

Cardiovascular risk markers (computed tomography‑coronary artery calcium and carotid intima‑media thickness) in patients with rheumatoid arthritis and controls.

Chronic inflammatory diseases, such as arthritis have been linked to a higher risk of developing cardiovascular disease. The present study examined the association between carotid intima-media thickness (CIMT) and coronary artery calcium (CAC), as well as the cardiovascular risk in patients with rheumatoid arthritis (RA). Additionally, the present study used 28 measures to calculate the disease activity score (DAS). To compare healthy controls with patients with RA, a case-control study was conducted that assessed CAC and CIMT in patients with the disease. A total of 45 healthy individuals and 45 patients with a diagnosis of RA were included in the study. With an average age of 50.66±12.35 years, the ages of the participants varied from 24 to 80 years. In both the control and RA patient groups, the sex ratio was 60%. The RA patient group had 53.3% female participants. There were significant variations in the levels of serum urea, potassium, magnesium, serum alkaline phosphatase, serum glutamic pyruvic transaminase, total leucocyte count, erythrocyte sedimentation rate, C-reactive protein (CRP) and lipids [apart from triglycerides and very low-density lipoprotein (VLDL)]. There was a substantial difference in the scores between patients with RA and the controls as regards CAC. A mild-severe risk of coronary artery disease was observed in 55.6% of RA cases and 4.4% of the controls (all mild). Both CIMT thickness and the CAC score exhibited a significant correlation with CRP, serum cholesterol, serum triglycerides, serum low-density lipids and serum VLDL. The DAS of patients ranged between 4.4 and 8.2 (mean, 5.81±0.91). A moderate disease activity was noted in the remaining patients, whereas 66.7% exhibited a high disease activity (DAS >5.2). On the whole, the present study demonstrates that conventional risk factors for cardiovascular disease, such as dyslipidemia, are consistent with both CIMT and CAC. The risk of developing atherosclerosis may be substantially increased by chronic inflammation, as the DAS score corresponds with CIMT and CAC.

Intervention effect of Cigu Xiaozhi prescription on ceramide lipoapoptosis in non-alcoholic fatty liver disease.

To explore the mechanism of the Chinese medicine Cigu Xiaozhi prescription (, CGXZ) in the treatment of the non-alcoholic fatty liver disease (NAFLD) by detoxification and phlegm-reducing, the effect of CGXZ prescription on ceramide-mediated lipid apoptosis in Hep G2 cells with NAFLD. The experiment was randomly divided into 6 groups: normal control group, model group, CGXZ prescription medicated serum high, medium, and low dose groups, and pioglitazone positive control group. Using 500 μmol/L free fatty acid (FFA) mixture to induce Hep G2 cells to establish NAFLD cell model, respectively, with 2%, 4%, and 6% concentration of CGXZ prescription medicated serum intervention for 24 h. The changes in organelles and lipid droplet accumulation were observed under the electron microscope. Furthermore, TdT-mediated dUTP Nick-End Labeling method was used to assay hepatocyte apoptosis; Biochemical determination of glutamic-pyruvic transaminase, glutamic oxalacetic transaminase, triglycerides, and FFA levels in Hep G2 cells; the content of ceramide was determined by high-performance thin-layer chromatography. Finally, Western Blot and quantitative real-time polymerase chain reaction (qRT-PCR) were used to determine the protein and gene expression levels, such as inducible nitric oxide synthase (iNOS), nuclear factor κB (NF-κB), B cell lymphoma 2 (Bcl-2) and Bcl-2-associated X (Bax). Under the electron microscope, the cells in the model group showed moderate-to-severe steatosis, and apoptotic bodies could be seen. The model group had greater improvements in the apoptosis rate (P < 0.01), and the levels of ceramide C2 and FFA in the cytoplasm (P < 0.01) than the normal control group. The protein expressions of NF-κB, iNOS, and Bax were significantly up-regulated (P < 0.05), while the Bcl-2 had no significant change (P > 0.05). Compared with the model group, the levels of ceramide C2 and FFA (P < 0.01), the protein expressions of NF-κB, iNOS, and Bax (P < 0.05) in the CGXZ prescription treatment group and pioglitazone positive control group were significantly decreased; Only the Bcl-2 protein was significantly up-regulated in the high-dose Chinese medicine group (P < 0.05). The down-regulation of Bax mRNA expression in each Chinese medicine treatment group was significantly better than in the pioglitazone positive control group (P < 0.01). The CGXZ prescription, formulated with the method of detoxification and phlegm, can inhibit lipoapoptosis in the NAFLD cell model by down-regulating the levels of ceramide C2 and FFA, which may be achieved by regulating ceramide/iNOS/NF-κB signaling pathway.
