RESUMEN
BACKGROUND: Physical exercise participation among female students is significantly compromised throughout the academic periods of college or university due to scholastic demands and also by less parental and community encouragements. Thus, physical inactivity in female college students leads to less musculoskeletal efficiency and work performance. OBJECTIVE: Customized yogic module may be considered to enhance both aerobic and anaerobic power, pulmonary capacity and musculoskeletal efficiency for the improvement of systemic body functions among female college students. METHODS: A randomized, controlled parallel study design (nâ=â60; ageâ=â20.16±2.05 years), on sedentary female college students practicing customized yogic module (nâ=â30) for 5 days / week for 3 months (60âmin daily in the morning) to observe anthropometric, physiological, cardiopulmonary and muscular endurance indices. RESULTS: After yogic practice, a significant reduction in body fat (pâ<â0.05) (%), heart rate (pâ<â0.001), systolic blood pressure (pâ<â0.001), double product (p<0.01) and rate pressure product (pâ<â0.05) were estimated. Significant improvement (pâ<â0.001) in vital capacity, forced expiratory volume in 1âsec was also observed. Evaluation of hand grip strength, maximal oxygen consumption and physical work capacity showed significant increase (pâ<â0.01) after yogic intervention. CONCLUSIONS: A three-month customized yogic training improved resting physiological activities, cardiopulmonary functions, musculoskeletal strength and endurance fitness due to focused breathing, mindfulness meditation and by stretching-strengthening patterns for achieving recreational physical activity among female college students.

BACKGROUND: The global COVID-19 lockdown restricted daily routines due to the psychological fear of infection, which imposed an unknown universal threat on female college students, affecting physiological health and well-being. However, scant information concerning the efficacy of yogic practice on female college students during the stressful COVID-19 pandemic situation is available. METHODS: In a randomized controlled trial (n = 74, age = 21.65 [4.05] y), a study was conducted with a well-conceptualized yogic module for 5 days/week for 3 months (40 min daily in the morning) among yogic volunteers. Pre-post analysis of anthropometric, physiological, and biochemical indices in pandemic-stressed female college students was done for the control and yoga groups. RESULTS: After 3 months of yogic practice, significant reduction (P < .05) in heart rate (d = 0.64, meandiff = 5.43), systolic blood pressure (d = 0.59, meandiff = 5.32), cortisol (d = 0.59, meandiff = 6.354), and triglycerides (P < .01, d = 0.45, meandiff = 13.95) was observed. After yogic follow-up significant improvement (P < .01) in high-frequency (d = 0.56, meandiff = -7.3), total power (d = 0.46, meandiff = -1150) and time domain parameters of heart rate variability led to ameliorate the stress index. Superoxide dismutase (P < .01, d = 0.78, meandiff = 0.69), catalase (P < .05, d = 0.48, meandiff = -7.37), glutathione (P < .001, d = 0.83, meandiff = -4.15), high-density lipoprotein (P < .05, d = 0.48, meandiff = -11.07), and dopamine (P < .001, d = 0.97, meandiff = -135.4) values along with inflammatory markers (P < .001) significantly improved among yogic volunteers after regular practice. CONCLUSIONS: Our findings suggest that a 3-month well-conceptualized yogic intervention during COVID-19 may be considered as a prophylactic tool to improve female college students' universal psychophysiological health by ameliorating autonomic functions, cardiometabolic risk factors, and immune metabolisms in an economical and environment-friendly manner.

Melatonin-rich and 1,8-cineole-rich extracts have been successfully obtained from yellow mustard (YM) and small cardamom (SC) seeds, respectively, employing green technology of supercritical CO2 (SC-CO2) extraction. Chemical profiling confirmed the presence of melatonin and 1,8-cineole and co-extractants in the respective extracts. Electron paramagnetic resonance spectroscopy attested strong antioxidant activities of the extracts foregoing pan-assay interference compounds involved in spectroscopic analysis. These extracts also exhibited synergistic efficacies greater than unity confirming antioxidant synergy among the co-extracted bioactives therein. To ascertain hypocholesterolaemic efficacies, these extracts were co-administered orally with Triton X (at the pre-optimised dose of 175 mg/kg body weight (BW)) to Wistar albino rats at doses of 550, 175 and 55 mg/kg BW. Serum total cholesterol levels in the rats were monitored on days 3, 7, 15 and 21. On day 21, total cholesterol level reduced appreciably by 49·44 % in rats treated with YM seed extract and by 48·95 % in rats treated with SC seed extract, comparable with atorvastatin-administered rats (51·09 %). Either extract demonstrated inhibitory effects on hepatic 3-hydroxy-3-methyl-glutaryl-CoA (HMG-CoA) reductase activity. A molecular docking exercise identified specific compounds in the extracts which possessed binding affinities comparable with therapeutically used HMG-CoA reductase inhibitors. In silico and in vivo studies concertedly concluded that the consortium of bioactive components in the extracts cannot be considered as invalid metabolic panaceas and therefore these 'green' extracts could be safely subjected to clinical studies as preventive biotherapeutics for hypercholesterolaemia. These extracts could be consumed per se as hypocholesterolaemic supplements or could be ingredients of new spice-based therapeutic foods.

Oxygen is very important to the existence of life. Oxygen deficiency, defined as hypoxia, elicits adaptive responses in cells and tissues. Lower oxygen concentration can cause the alteration of renal function, affects the maintenance of a balance of the body fluids, electrolytes, pH, and blood pressure homeostasis. Impaired fluid regulation could, in addition, contribute to the precipitation of pulmonary edema and exacerbate hypoxemia which may accelerate the progression of chronic kidney disease. In this context, the present study attempted to evaluate the association of renal injury and oxidative stress at different atmospheric pressures (1829, 3657, and 5486 m). Limited fecal analysis of experimental animals was also done to evaluate the impact of hypobaric hypoxia on the composition of dominant gastrointestinal microbiota. The study was performed on 24 male Wister strain rats and divided into four groups (C, HA-I, HA-II, and HA-III), and exposure was carried out for seven days period. In hypoxic exposure rats, plasma urea, creatinine, electrolytes and malonaldehyde level elevated and catalase and superoxide dismutase level diminished significantly compared to the controls. Increase in blood uremia profile, toxicity markers, and lipid peroxidation marker enzymes indicated that hypoxia causes renal failure. Histological structures of the kidney of group HA-II and HA-III animals showed severe disorganization of glomerulus and dilation of renal tubules. These results indicate nephrotoxicity or acute renal failure can occur at hypobaric hypoxia and it also affected the gut microbial population. This alteration was observed significantly above 3000 m.

BACKGROUND: Currently kidney disease appears a foremost problem across the world. Acetaminophen is a commonly used antipyretic agent, which in high doses, causes uremia and used for experimentally induction of kidney disease. Bacteriotherapy affords a promising approach to mitigate uremic toxins by ingestion of urease positive bacteria, probiotics and symbiotic able to catabolize uremic solutes within the gut. The present study evaluates the effect of seven commercial symbiotic on kidney disease. METHODS: Fifty-four albino male rats were randomly divided into nine groups. Control group (Group-I) received distilled water interperitoneally for 7 days. Positive control group (Group-II) received 500 mg/kg acetaminophen interperitoneally for 7 days. Commercially available seven symbiotic combinations at a dose of 10(9)cells/day for 3 weeks was administered to the tested groups (Group III-IX) after receiving 500 mg/kg/day acetaminophen interperitoneally for 7 days. Blood, kidney, liver and stool samples were collected after scarification for biochemical tests and DNA fragmentation assay of kidney tissue, kidney histological studies. Limited fecal analysis was conducted. RESULT: Blood urea nitrogen and toxicity indicators were increased, and antioxidant enzymes were decreased in Group-II. Blood urea nitrogen, toxicity indicators, glomerular necrosis, DNA damage of kidney tissue were reduced, and antioxidant enzymes were increased significantly in the treated Groups IV and IX (p < 0.05) in response to Group-II. Number of pathogenic bacteria decreased in synbiotic treated groups than Group I and II. CONCLUSION: The study demonstrated that some of commercial symbiotic combination can reduce the sever effect of kidney disease.

OBJECTIVE: To investigate phytochemical screening, antimicrobial activity and qualitative thin layer chromatographic separation of flavonoid components, antioxidant activity and total flavonoid compound of Terminalia arjuna. METHODS: For phytochemical screening, some common and available standard tests were done. Antimicrobial bioassay was done through agar well diffusion method. Detection of antioxidant activity and flavonoid compounds were done through thin layer chromatography. Total antioxidant activity was measured by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) in colorimetric method. Aluminum chloride colorimetric method was used for total flavonoid determination. RESULTS: Phytochemical screening showed the active compounds presence in high concentration, such as phytosterol, lactones, flavonoids, phenolic compounds and tannins and glycosides. The antimicrobial activity of extract showed that greater inhibition zone against Gram negative bacteria than Gram positive bacteria. This methanolic extract showed a promising antioxidant activity, as absorption of DPPH redicles decreased in DPPH free radical scavenging assay. Flavonoids components having antioxidant property present in the methanol extract at a level of 199.00 mg quercetin equivalent/g of dried methanol extract in colorimetric method. CONCLUSIONS: The Terminalia arjuna bark extract revealed the presence of bio-active constituents which are known to exhibit medicinal as well as physiological activities.

The total antioxidative activity of L. ingluviei ADK10 isolated from chicken intestine intact cells and cell free culture supernatant (CFCS) was 54- 67.95%. The ability to scavenge a,a-Diphenyl-b-Picrylhydrazyl free radical ranged from 71 and 64% in intact cells and CFCS respectively. Total reducing activity of bacteria was equivalent to 290 microM/L of cysteine. Reducing glutathione activity was equivalent to 93.95 microg/mL. Oral administration of the strain at a dose of 10(9) cfu/kg body weight to acetaminophen induced oxidative stress in rats increased catalase, glutathione and superoxide dismutase activity in the blood, liver and kidney and lowered malondialdehyde level. The results indicate that L. ingluviei ADK10 has potential free radical scavenging activity for the treatment of oxidative stress related disease.

OBJECTIVES: Acetaminophen is a commonly used antipyretic agent which, at high doses, causes renal tubular damage and uremia. Bacteriotherapy affords a promising approach to mitigating uremic intoxication by ingestion of live microbes able to catabolize uremic solutes in the gut. The present study evaluates the nonpathogenic soil-borne urease-positive bacterium Sporosarcina pasteurii (Sp) as a potential urea-targeted component for such an "enteric dialysis" formulation. METHODS: Twenty-four albino male rats were randomly divided into 4 groups: The control group (group NC) received distilled water intraperitoneally for 7 days. The positive control group (group U) received 500 mg/kg acetaminophen intraperitoneally for 7 days. The tested group (group UP) was administered Sp at a dosage of 10(9) cells/day for 5 weeks, after receiving 500 mg/kg per day of acetaminophen intraperitoneally for 7 days. Vehicle control (group VC) received only Sp at a dosage of 10(9) cells/day for 5 weeks without acetaminophen treatment. Blood, kidney, liver and stool samples were collected after scarification, for biochemical (urea, creatinine, malondialdehyde, superoxide dismutase, catalase, glutamate oxaloacetate transaminase [GOT] and glutamate pyruvate transaminase [GPT] of blood, kidney and liver) tests. Limited fecal analysis was performed. RESULTS: Blood urea nitrogen (urea, creatinine) and toxicity indicators (GOT, GPT) were increased, and antioxidant enzymes were decreased in group U. Blood urea nitrogen and toxicity indicators were reduced, and antioxidant enzymes were increased significantly in the group UP (p<0.05) compared with group U. The number of Sp was increased in Sp-treated groups compared with groups NC and U. CONCLUSIONS: The study demonstrated that the bacteria tested reduced blood urea nitrogen levels significantly.

Dehydration or water deprivation in the body decreases urinary excretion and allows urea and other protein waste products to accumulate in the blood. The aim of the present study is to evaluate the association of uremia and oxidative stress by applying the herbal plant Withania somnifera (W. somnifera) (Aswagandha). The study was performed on male Wister strain rats in which, dehydration was achieved by water withdrawal. A total of 18 rats were studied and were randomly divided into three Groups: Group-1, control, Group-2, only dehydration and Group-3, dehydration + administration of aqueous root extract of W. somnifera, orally (50 mg/100 gm body weight/day) for 25 days. After 25 days of treatment, it was observed that the body weight of Group-3 animals had increased significantly, while that in Group-2 had decreased significantly. The liver enzymes in both blood and kidneys did not show any significant change in the three groups implying absence of any toxicity of the root extract. In Group-2 animals, the serum urea and creatinine levels increased sig-nificantly when compared with animals in Groups-1 and 3. The low levels of serum urea and crea-tinine in Group-3 animals indicates the protective effect of the plant extract against renal injury caused by dehydration. Dehydration-induced oxidative stress was established in our study by noting the low activities of super-oxide dismutase and catalase, both important antioxidant enzymes, in Group-2 animals; both enzymes were stabilized in animals of Groups-3 and 1. In conclusion, it is hypothesized that there is an antioxidative role of W. somnifera resulting in reducing the extent of renal injury as a result of oxidative stress.
