RESUMEN

A collection of metabolic disorders and neurodegenerative diseases linked to oxidative stress and neuroinflammation frequently affect postmenopausal women or estrogen deprivation. Recent research has focused on alternative therapies that can enhance these women's quality of life. This study set out to investigate the effects of physical exercise (EX) and intermittent fasting (IF) on oxidants/antioxidants, inflammatory cytokines, neurotransmitters, and brain-derived neurotrophic factor (BDNF) in the cortex of rats. Additionally, it sought to assess the response to oxidative stress and neuroinflammation in the brains of rats following ovariectomy (OVX) and the potential mechanisms of these interventions. Fifty female rats were divided into one of the following groups 30 days after bilateral OVX: Control, OVX, OVX + EX, OVX + IF, and OVX + EX + IF groups. The rats in the Control and OVX groups continued their normal activities and had unrestricted access to food and water, but the rats in the OVX + EX and OVX + EX + IF groups had a 4-week treadmill training program, and the rats in the OXV + IF and OVX + EX + IF groups fasted for 13 h each day. The rats were killed, the cerebral cortex was taken, tissue homogenates were created, and various parameters were estimated using these homogenates. The results show that ovariectomized rats had decreased levels of neurotransmitters (DA, NE, and SE), acetylcholinesterase, brain GSH (glutathione), SOD (superoxide dismutase), catalase, GPx (glutathione peroxidase), and TAC (total antioxidant capacity), as well as elevated levels of proinflammatory cytokines and mediators (TNF-α, IL-1ß, Cox-2). While ovariectomy-induced declines in neurotransmitters, enzymatic and nonenzymatic molecules, neuroinflammation, and oxidative brain damage were considerably mitigated and prevented by treadmill exercise and intermittent fasting, BDNF was significantly increased. These results suggest that ovariectomy can impair rat neuronal function and regular treadmill exercise and intermittent fasting seem to protect against ovariectomy-induced neuronal impairment through the inhibition of oxidative stress and neuroinflammation and increased BDNF levels in the brain cortex. However, combining regular exercise and intermittent fasting did not provide additional benefits compared to either treatment alone.

RESUMEN

Introduction Those who practice self-care using over-the-counter (OTC) products believe that these medications are relatively safe. They can be used to treat mild illnesses that do not require medical consultation. However, improper self-medication using OTC medicines because of inadequate knowledge of their side effects and interactions can result in drug-related issues and even death. The current study was performed using the foundation year students of Princess Nourah Bint Abdul Rahman University (PNU) as subjects, to examine the use of OTC medicines during examination times. Methods This cross-sectional study was done on 213 (response rates 87.7%) foundation-year female students in the Health Colleges at PNU in Riyadh. Using a 26-item, self-administered, online questionnaire, data were collected. Results It was found that more than 50% of the students used OTC medicines habitually during exam periods. A majority (90.6%; p< 0.0001) of the students mentioned that the overuse of Panadol Extra was very safe while 67.6% (p< 0.0001) of them declared that nonsteroidal anti-inflammatory drugs (NSAIDs) would not induce stomach ulcer formation. A higher percentage (67.6%; p<0.0001) of the students confirmed using OTC medicines during exam time for headache relief. A higher percentage (72.8%; p< 0.0001) of the students indicated that because the OTC medications were readily available and they believed these drugs were safe, they used sizable quantities during the time of the examinations. Furthermore, 69% (p< 0.0001) of the students confessed that because of a friend's recommendations, they started trying OTC medicine. Above 67% (p< 0.0001) stated that OTC medications are inexpensive and easily available in Saudi Arabia. Conclusion To conclude, the findings of this study reiterated the high usage of OTC medicines by female students during the time of examination, and the highest used were painkillers.

RESUMEN

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in women. Despite the significant burden of CVD, knowledge and awareness of its risk factors among women are low. This review aimed to identify CVD awareness, knowledge, and risk factors for women of reproductive age from different countries and variables that influence health outcomes. Studies published from 2000 to 2023 were reviewed using PubMed, ScienceDirect, Elsevier, and electronic databases. A total of 50 studies were found, and 41 were excluded. The keywords used were "Knowledge of the risk factor of heart disease," "cardiac risk factors," "cardiovascular disease," "heart disease awareness," and "heart disease," combined with "women" and "reproductive age." The review revealed significant gaps in the general awareness and knowledge of CVD risk factors among women of reproductive age. Many women were unaware of the symptoms and risk factors associated with CVD, leading to delayed diagnosis and poorer outcomes. Lack of education, low socioeconomic status, and limited access to healthcare were identified as contributing factors to this knowledge gap. Young women, particularly those with poor pregnancy outcomes, demonstrated limited awareness and perception of CVD risk. The findings suggest significant gaps in general awareness, knowledge of CVD risk, risk factors among women of reproductive age from different countries, and factors that influence their health outcomes. Targeted interventions are urgently needed to improve awareness and knowledge of CVD among women of reproductive age. Efforts should focus on educating women about CVD risk factors and prevention strategies before symptoms arise. Addressing socioeconomic and educational disparities is crucial to bridging the gap in awareness. By enhancing awareness and knowledge, women can be empowered to take preventive actions and reduce their risk of developing CVD. As a result, we recommend that there are significant opportunities to educate women about CVD risk and prevention before symptoms arise. In addition, there is a need to develop effective interventions to raise awareness among women of reproductive age to close the gap in awareness and knowledge of CVD.

RESUMEN

The complicated disorder of hypercholesterolemia has several underlying factors, including genetic and lifestyle factors. Low LDL cholesterol and elevated serum total cholesterol are its defining features. A carotenoid with antioxidant quality is lycopene. Examining lycopene activity in an animal model of hypercholesterolemia induced using food was the aim of this investigation. Triglycerides, LDL cholesterol, HDL cholesterol, and plasma total cholesterol were all measured. Biomarkers of renal and cardiac function were also examined. Apoptotic indicators, pro-inflammatory markers, and oxidative stress were also assessed. Additionally, the mRNA expression of paraoxonase 1 (PON-1), peroxisome proliferator-activated receptor gamma (PPAR-γ), and PPAR-γ coactivator 1 alpha (PGC-1α) in cardiac and renal tissues was examined. Rats showed elevated serum lipid levels, renal and cardiac dysfunction, significant oxidative stress, and pro-inflammatory and apoptotic markers at the end of the study. Treatment with lycopene significantly corrected and restored these changes. Additionally, lycopene markedly increased the mRNA expression of PGC-1α and PON-1, and decreased PPAR-γ expression. It was determined that lycopene has the capacity to modulate the PPAR-γ and PON-1 signaling pathway in order to preserve the cellular energy metabolism of the heart and kidney, which in turn reduces tissue inflammatory response and apoptosis. According to these findings, lycopene may be utilized as a medication to treat hypercholesterolemia. However, further studies should be conducted first to determine the appropriate dose and any adverse effects that may appear after lycopene usage in humans.

RESUMEN

The frequency of overweight and obesity is rising globally. These disorders are prevalent health problems. It has a substantial correlation with a number of health issues, including cardiovascular, metabolic, and diabetes mellitus disorders. Lycopene (Lyc) is an acyclic structural isomer of ß-carotene and has powerful antioxidant properties with various promising therapeutic effects. In this study, rats fed a high-fat diet were examined to determine how lycopene affected metabolic syndrome and kidney damage. After being acclimated, rats were divided into 5 groups (n = 8/group) as follows: the first group served as the control and was fed on a normal pelleted diet (4.25% fat) until the end of the experiment. The second group (high-fat diet; HFD) was fed on a high-fat diet (45.5 kcal% fat) composed of 24% fat, 24% protein, and 41% carbohydrate. The third and fourth groups were fed on HFD and administered lycopene at 25 and 50 mg/kg bodyweight orally every day. The fifth group (standard drug group) received HFD and simvastatin (SVS; 10 mg/kg bodyweight orally daily) for 3 months. Tissue samples from the kidney were taken for determination of the biochemical parameters, lipid peroxidation (LPO), protein carbonyl (PC), reduced glutathione (GSH), total thiol group, antioxidant enzymes, namely, superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and glutathione reductase (GR), in addition to renal mRNA expression of nuclear factor erythroid 2-related factor 2 (Nrf2), renal levels of inflammatory markers [tumor necrosis factor alpha (TNF-α), interleukin-1 beta (IL-1ß), and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB)], and apoptotic markers (BCL2 Associated X (Bax), B-cell lymphoma 2 (Bcl-2), and Bax/Bcl-2 ratio). When compared to the control group, the HFD group's food consumption, body weight, serum levels of glucose, uric acid, creatinine, LPO, PC, TNF-α, IL-1ß, Bax, and the Bax/Bcl-2 ratio all increased significantly. In the kidney sample of HFD-fed rats, there was a downregulation of Nrf2 mRNA expression along with a significant reduction in the enzymatic activity of SOD, CAT, GR, and GPx. Lyc treatment was able to successfully reverse HFD-mediated changes as compared to the HFD group. Consuming lyc helps to prevent fat and renal damage in a positive way.

RESUMEN

A metabolic disease called hypercholesterolemia is connected to both oxidative damage and inflammation. The goal of the current investigation was to determine if olive oil and palm oil could prevent hypercholesterolemia-induced oxidative stress in the liver of rats fed a high-cholesterol diet (HCD). The experimental mice were given HCD for three months while also receiving 0.5 mL/kg of either palm or olive oil. Serum triglycerides, total cholesterol, LDL cholesterol, vLDL cholesterol, and the atherogenic index all significantly increased in HCD-fed rats, while HDL cholesterol significantly dropped. Additionally, HCD caused a notable rise in proinflammatory cytokines and serum transaminases in liver tissue. Additionally, HCD significantly increased the production of nitric oxide and lipid peroxidation in the liver while decreasing antioxidant enzymes. Treatment with palm and olive oils dramatically reduced the levels of pro-inflammatory cytokines and lipid peroxidation, improved antioxidant defenses, and considerably improved liver function indicators. Additionally, the examined oils dramatically decreased the expression of fatty acid synthase (FAS) in the liver of rats receiving HCD. In conclusion, HCD-fed rats exhibit significant antihyperlipidemic and cholesterol-lowering benefits from palm and olive oils. The improved antioxidant defenses, lower inflammation and lipid peroxidation, and altered hepatic FAS mRNA expression were the main mechanisms by which palm and olive oils produced their advantageous effects.

RESUMEN

Aging and age-related disorders are prominent issues. Aging is associated with a gradual impairment of physiology at the genetic, cellular, tissue, and whole organism level that directly influences the development of chronic diseases and organ failure. Blueberries, on the other hand, are well known for their high content of bioactive compounds and have demonstrated positive impacts on metabolic factors that influence health and general well-being. This study is aimed at evaluating the ameliorating the effects of blueberry on the liver of aged rats by monitoring changes in metabolic disturbances, oxidative stress, and inflammatory disruption. The aged group of rats was orally administered with blueberry extract (200 mg/kg) for a period of 4 weeks. The results revealed that aging was associated with an increase in body weight, liver weight, and metabolic parameters like serum insulin, triglycerides, total cholesterol, and liver function markers accompanied with a decrease in vitamin D levels. Furthermore, the results showed a significant diminish in the activities of antioxidant enzymes, glutathione content with an elevation in lipid peroxidation, inflammatory mediators (tumor necrosis factor alpha, interleukin 6, and nuclear factor kappa-light-chain-enhancer of activated B cells) as well as fibrotic markers (TGF-ß1) in the liver of aged rats. Compared to the young rats (control group), blueberry effectively reversed age-mediated disruption of the aforementioned parameters. Hence, blueberries can be used as a potential therapeutic strategy for the management of age-related liver dysfunction and disease.

RESUMEN

Obesity is a global epidemic disease that is closely associated with various health problems as Diabetes mellitus, cardiovascular, and metabolic disorders. Lycopene (LYC), a red-colored carotenoid, has demonstrated various promising therapeutic effects. Hence, the potential of LYC was studied against high fat diet (HFD)-induced obesity and metabolic disturbances in rats. Animals fed on HFD and orally supplemented with LYC (25 and 50 mg/kg) or simvastatin (10 mg/kg) every day for 3 months. The results revealed that long-term consumption of HFD significantly increased weight gain, liver weight, cholesterol, triglycerides (TG), apolipoprotein-B (Apo-B), low-density lipoprotein-cholesterol (LDL-c) levels, as well as decreasing the high-density lipoprotein-cholesterol (HDL-c) levels. Moreover, high blood glucose and insulin levels accompanied by low peroxisome proliferator activated receptor gamma (PPAR-γ) were recorded in HFD group. Further, HFD rats displayed lower levels of antioxidant biomarkers (SOD, CAT, GPx, GR and GSH), in addition to higher levels of MDA, NO and inflammatory mediators (IL-1ß, TNF-α, and MPO). Marked increases were observed in atherogenic index, lactate dehydrogenase and creatine kinase together with fibrosis markers (TGF-ß1 and α-SMA) in rats fed on HFD. Comparing to model group, LYC was able to effectively reverse HFD-mediated alterations at dose dependent manner. Altogether, dietary supplementation of LYC successfully reversed HFD-induced alterations through its antioxidant, anti-inflammatory, and anti-fibrotic properties. Hence, LYC displayed a therapeutic potential to manage obesity and its associated pathologies.

RESUMEN

The present study was designed to investigate the nephrotoxicity of silver nanoparticles (AgNPs; 80 mg/kg; > 100 nm) and to evaluate the protective effect exercised by Beta vulgaris (beetroot) juice (RBR; 200 mg/kg) on male rats' kidney. Serum-specific parameters (urea, creatinine, electrolytes and histopathology of kidney tissue) were examined to assess the AgNPs nephrotoxicity effect. Moreover, this study analysed oxidative stress (lipid peroxidation, glutathione, superoxide dismutase and catalase) and anti-apoptotic markers (Bcl-2). AgNPs intoxication increased kidney function marker levels and lipid peroxidation and decreased the glutathione, superoxide dismutase and catalase activities in kidney tissue. Additionally, Bcl-2 expression was downregulated following AgNPs intoxication. Moreover, AgNPs induced a significant increase in renal DNA damage displayed as an elevation in tail length, tail DNA percentage and tail moment. Interestingly, RBR post-treatment restored the biochemical and histological alterations induced by AgNPs exposure, reflecting its nephroprotective effect. Collectively, the present data suggest that RBR could be used as a potential therapeutic intervention to prevent AgNPs-induced nephrotoxicity.

RESUMEN

This study was designed to investigate the potential defensive strategy of Sana Makki extract (SME) against Cd-induced in vivo nephrotoxicity and its underlying mechanisms. Male albino rats were used in a thirty days study comparing control, SME-treated, CdCl2-treated, and combined SME and Cd treatment. Pre-treatment with SME significantly reduced serum kidney biomarkers (urea and creatinine), the concentration of renal KIM-1, and kidney index values. Additionally, SME also attenuated CdCl2-induced oxidative and nitrosative stress in renal tissue; significantly reducing malondialdehyde (MDA) and nitric oxide (NO) concentrations and significantly increasing antioxidant enzymes in kidney tissue. Molecularly, SME significantly upregulated antioxidant gene expression (SOD2, GR, GPx1, and CAT) caused by Cd. Notably, the augmented mRNA expression of nuclear-related factor 2 (Nrf2) by Cd was enhanced by SME administration. SME markedly suppressed the Cd-induced rise in pro-inflammatory cytokines. The combination of Cd and SME relieved the Cd-induced apoptotic damage by enhancing Bcl2 and suppressing Bax and Cas-3 levels in renal tissue. The renal tissue histoarchitecture confirmed the biochemical and molecular findings. Collectively, our data indicate that SME can counteract Cd-induced renal intoxication through anti-oxidative, anti-inflammatory, and anti-apoptotic mechanisms.

RESUMEN

INTRODUCTION: Nanoparticles are at the forefront of rapidly developing nanotechnology and have gained much attention for their application as an effective drug delivery system and as a mediated therapeutic agent for cancer. However, the cytotoxicity of nanoparticles is still relatively unknown and, therefore, additional study is required in order to elucidate the potential toxicity of these nanoparticles on cells. MATERIALS AND METHODS: Thus, the following work aimed to investigate the capability of Beta vulgaris (beetroot) water extract (BWE; 200 mg/kg) to protect hepatic tissue following silver nanoparticles (AgNPs; 80 mg/kg; >100 nm) intoxication in male rats. RESULTS: AgNPs-intoxication elevated the liver function markers - including serum transaminases and alkaline phosphatase activities - and decreased serum levels of albumin and total proteins, in addition to disturbing the oxidation homeostasis. This is evidenced by the increased lipid peroxidation, the depleted glutathione, and the suppressed activity of superoxide dismutase and catalase. In addition, an apoptotic reaction was observed following AgNPs treatment, as indicated by the up-regulation of p53 and down-regulating Bcl-2 expressions, examined by the immunohistochemistry method. Furthermore, AgNPs exhibited a marked elevation in liver DNA damage that was indicated by an increase in tail length, tail DNA% and tail movement. However, BWE eliminated the biochemical and histological alterations, reflecting its hepatoprotection effect in response to AgNPs. DISCUSSION: Collectively, the present data suggest that BWE could be used following AgNPs as a potential therapeutic intervention to minimize AgNPs-induced liver toxicity.

RESUMEN

Coccinia grandis (C. grandis) L is an Indian medicinal plant from the Cucurbitaceae family whose extracts possess anti-oxidant, anti-infective, and anti-inflammatory properties. The objective of the present study was to probe the potential immunomodulatory of C. grandis crude extract on different pathways in THP-1 cells as probed by changes in expression of several proteins. THP-1 cells were differentiated into macrophages after treatment with phorbol-12-myristate 13-acetate, followed by exposure to lipopolysaccharide (LPS) with or without 50 or 100 µg/ml of C. grandis extract. Treatment of the cells with the extract significantly downregulated the expression and release of pro-inflammatory cytokines (IL-6, IL-1ß, CCL2, CCL22, CXCL10/IP-10, CX3CL1 and CXCL8/IL-8), proteins (ERK5, BAX, BCL2, Cyclin D, ERK1, NF-κB, P-IκBα,P- NF-κB and P-p38) and molecular signaling pathways (NF-κB, p38 MAPK, ERK1/2 and IL-6/JAK/STAT3 signaling cascades). This study is the first to highlight the ability of C. grandis extract to modulate several pathways, including proliferation, the expression of inflammatory cytokines, phagocytosis, migration properties and apoptosis, in human monocytic THP-1 cells.

RESUMEN

The present study aimed to investigate the influence of grape seed extract (GSE) in renal toxicity, oxidative stress, and Bcl-2 expressions in Eltroxin-induced hyperthyroidism to male mice. GSE was evaluated through oral administration to male mice at dose 50 mg/kg daily for 3 consecutive weeks. Eltroxin (100 µg/kg) was administered to mice for 3 weeks, and the mice were posttreated with GSE for another 3 weeks. Results revealed that GSE administered to normal mice did not produce any signs of toxicity and did not cause any biochemical or histopathological changes. Posttreatment of Eltroxin-induced hyperthyroidism mice with GSE daily for 3 weeks improved all examined biochemical or histopathological features. Oral GSE can significantly normalize the elevated level of T3 and T4 in hyperthyroidism animals and elevated the reduced levels of TSH. Moreover, serum urea, creatinine, and electrolyte levels were significantly improved. GSE showed a potent antioxidant capacity in all oxidative stress markers assays (TBARS, reduced GSH, GST, SOD, and CAT) of kidney tissue homogenates. Furthermore, histopathological examination of kidney tissue of Eltroxin + GSE-treated group confirms the potential nephroprotective effect of GSE through increasing the anti-apoptotic marker Bcl-2.

RESUMEN

OBJECTIVE: To find out the potential role of nutritional components in improving brain function among patients with Alzheimer`s disease (AD). METHODS: The correlation between nutrition and cerebral function in cases of AD has been the focus of 19 prospective randomised controlled trials (RCTs) with a combined research sample of 2297 patients. These RCTs are subject to systematic review and meta-analysis in the current paper RESULTS: Findings showed that chain-free secondary saturated fatty acids (SFA) and trans fatty acids (TFA) occurred in higher concentrations in AD patients` brains than in controls. Furthermore, neuroinflammation was caused by remodelling of the lipid membrane and AD patients` cognitive function was impacted by alterations in tyrosine, tryptophan, purine, and tocopherol pathway metabolomics. Moreover, in cases of mild-to-moderate AD, reduction in functionality was induced by administration of alpha-tocopherol for more than 12 months. Consumption of Souvenaid helps in synaptic synthesis, which enhances functional connectivity. Furthermore, consumption of the B vitamins folate, cobalamin and pyridoxine at dosages of 0.8 mg, 0.5 mg and 20 mg per day, respectively, over a period of one year resulted in lower plasma tHcy levels and brain atrophy. CONCLUSION: Chain-free SFA and TFA occur in greater amounts in the brains of individuals with AD than in those without AD.

RESUMEN

The use of synthetic azo dyes as coloring agents in food products has dramatically increased. This study evaluated the effect of perinatal exposure to tartrazine (TZ) on mice offspring, focusing on neurobehavioral alterations and oxidative stress. The female mice received TZ (2.5 and 5 mg/kg) via oral gavage during pregnancy and the first 15 days after birth. At days 21 and 35 after birth, male mice were sacrificed, and samples were collected for analyses. Perinatal exposure to TZ triggered tissue injury evidenced by the histological alterations and neuronal damage in the cerebrum, medulla oblongata, and cerebellum. TZ provoked lipid peroxidation and diminished cellular antioxidants in different brain regions of the newborns. In addition, TZ increased hemoglobin content, as well as erythrocytes, leukocytes, and platelets count at days 21 and 35 after birth. Both the locomotor behavior and anxiety reflex were significantly altered in mice exposed to TZ. In conclusion, perinatal exposure to TZ within an adequate daily intake range induced oxidative stress and neurobehavioral and hematological alterations in mice offspring. Therefore, consuming foods containing TZ during pregnancy and lactation warrants public awareness.

RESUMEN

BACKGROUND: Pulicaria crispa (P. crispa) is a plant from the Compositae family that exhibits antioxidant, anti-inflammatory, antibacterial, and cytotoxic activities. OBJECTIVE: The current study aimed at investigating the immunomodulatory effects of P. crispa extract in lipopolysaccharide- (LPS-) stimulated human monocytic THP-1 cells. METHODS: To induce macrophage differentiation, THP-1 cell lines were treated with phorbol-12-myristate 13-acetate, followed by exposure to LPS with or without 50 or 100 µg/ml of P. crispa extract. The following tests were employed to test the immunomodulatory effects of the extract: MTT assay, ELISA, Western blotting analysis, cell migration and phagocytosis assays, and Annexin V staining method. RESULTS: Exposure to 100 µg/ml P. crispa extract significantly reduced THP-1 cell proliferation, migration, and phagocytosis (in LPS-stimulated cells, but not in unstimulated cells). Moreover, the extract alone significantly reduced the rate of THP-1 cell apoptosis, while it increased the rate of late apoptosis. Molecular investigations showed that treatment with P. crispa extract significantly upregulated the expression of ERK1, p-MAPK, P-P38, and Bcl2, while it significantly reduced the expression of ERK5, Bax, NF-κB, P-NF-κB, CCL1, CCL2, CCL5, CCL22, CXCL1, and CXCL10. CONCLUSION: Pulicaria crispa extract exhibited anti-inflammatory, antiproliferative, antimigratory, and antiphagocytic effects in LPS-stimulated THP-1 cells. Future studies should investigate these mechanisms in animal models with chronic inflammatory diseases.

RESUMEN

The goal of our investigation is to evaluate the potential protective efficacy of red beetroot extract (RBR) against testicular toxicity produced by CPF in rats. CPF exposure decreased the weight of testis and the levels of luteinizing hormone, follicle stimulating hormone and testosterone. CPF impaired also the oxidative status in favor of pro-oxidant molecules in the testicular tissue. Additionally, CPF stimulated the production of pro-inflammatory cytokines and their gene expression. Concomitantly, an apoptotic cascade has been observed upon CPF intoxication. However, RBR administration protected the testis tissue through modulating the hormonal level, inhibiting the oxidative damage, inflammation and the apoptotic responses following CPF intoxication. The obtained data recommend the use of RBR to prevent CPF-induced testicular damage via antioxidant, anti-inflammatory, and anti-apoptotic pathways.

RESUMEN

The aim of the present study was to evaluate the association between Bone mineral density in lumber spine and femoral neck with serum total levels of vitamin D, sun exposure and Consumption of vitamin D Supplement in obese Saudi females aged between 30 and 54 years old. Recent attention to the high prevalence of osteoporosis and its association with low vitamin D levels in adults has raised the importance of vitamin D evaluation. A low level of vitamin D is considered to be one of the most important risk factors for osteoporosis. In this study; 120 obese Saudi females with no diagnosed chronic diseases attending the Outpatient clinic at king Khalid University hospital in Riyadh. Saudi Arabia, recruited randomly in period of 12 months. In this study, Serum levels of total Vitamin D were considered to be severe deficient if it was lower than 25 ng/mL, mild to moderate deficient if it was between 25 and 60 ng/mL and optimum level if it was 61-200 ng/mL. The results showed that; sun exposure was significantly affect and Correlate with serum level of Vitamin D in the subjects. In addition, daily consumption of Vitamin D supplement was significantly affect and Correlate with serum level of Vitamin D in the subjects of this study. Moreover, the results showed that; 50% of the age group (40-49 years old) having severe deficiency of Vitamin D. While, 50% of the age group (50-59 years old) having optimal level of Vitamin D. And these results mean that age is not Correlated with vitamin D deficiency in subjects of this study.

RESUMEN

It is common for food to be made more palatable through the use of the flavour enhancer monosodium glutamate, also known as vetsin powder. The purpose of the study described in this paper was to explore how vetsin-induced hepatic toxicity, DNA fragmentation, damage, and oxidative stress modifications could be mitigated with moringa leaf extract (MLE). To that end, 40 male rats were separated into four groups: normal control, positive control or MLE, vetsin, and vetsin combined with MLE. Results indicated that, compared to the control group, the levels of serum alanine aminotransferase (ALT), aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), liver malondialdehyde (MDA), DNA damage, injury, PCNA, and P53 expressions were significantly enhanced by the administration of vetsin (P < 0.05). However, the vetsin group had significantly reduced levels of albumin, globulin, total protein, liver glutathione (GSH), superoxide dismutase enzyme (SOD), catalase, and glutathione S-transferase (GST) enzyme activities (P < 0.05) by comparison to control. Meanwhile, modifications in liver functions, oxidative stress, DNA damage, liver injury, and PCNA expression were alleviated when vetsin was administered alongside MLE. The authors conclude that vetsin may have many side effects and that MLE can ameliorate biochemical changes, oxidative stress, hepatic injury, PCNA, and P53 alterations induced by vetsin administration.
