Abstract
The study was performed to evaluate the neuroprotective effects of Benfotiamine (BFT) in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced Parkinson's disease (PD) in rats. The rats were given daily doses of BFT (100 mg/kg, 200 mg/kg) through oral administration for 42 days. The rats were given a single bilateral dosage of MPTP (0.1 mg/nostril) intranasally once before the drug treatment to induce PD. On day 42, the animals were subjected to various behavioral paradigms. Post-treatment with BFT for 42 days significantly improved the motor and nonmotor fluctuations of MPTP. The results demonstrated that treatment with BFT ameliorated MPTP-induced disorders in behavior, body balance, and dopamine levels in the mid-brain. Among the post-treated groups, a high dose of BFT was the most effective treatment. Mean values are indicated in ±SEM, n = 5***(p < 0.001) when compared with the vehicle control, n = 5 ### (p < 0.001) when compared with the disease control; (p < 0.001) when compared with the BFT per se; (p < 0.001) when compared with the low dose of BFT; (p < 0.001) when compared with the high dose of BFT. Our finding suggests that BFT contributed to superior antioxidant, and anti-inflammatory and could be a novel therapeutic method for PD management. In conclusion, BFT could be a potential drug candidate for curbing and preventing PD.

Abstract
Background Parkinson's disease (PD) is one of the major neurodegenerative disorders and the prevalence is expected to increase during the next couple of decades. There is a need for safe and effective therapeutic regimen that can effectively manage this neurotoxicity. The leaves and several other parts of Cordia dichotoma are known to possess number of medicinal properties. The purpose of this study was to examine the neuroprotective role of Cordia dichotoma in an experimental model of haloperidol-induced P.D. Materials and methods Five groups of rats were randomly assigned into different groups. Intraperitoneal haloperidol 1 mg/kg was given to the inducer group and 0.5% CMC to the normal control. The reference standard was syndopa 10 mg/kg, p.o., and the test group animals received C. dichotoma's ethanolic extract at 200 and 400 mg/kg orally for one week. Rats exposed to haloperidol were assessed for behavioral, neurochemical, and histopathological parameters. Results C. dichotoma leaves extract dose-dependently increased behavioral activity and muscle coordination. The extract at 400 mg/kg was found to increase significantly (P < 0.001) the central square activity in open-field test, compared to haloperidol treated rats. In stepping test, both tested doses of C. dichotoma (200 mg and 400 mg/kg) were found to significantly (P < 0.001) reduce akinesia, besides these doses also decreased the catatonic responses induced by haloperidol. Further, the extraction treatment (200 mg and 400 mg/kg) significantly (P < 0.001) decreased malonaldehyde and increased antioxidant enzymes like catalase compared to the control group. Histopathological changes in the test group showed a significant reduction in haloperidol damage to normal morphology in cortical, hippocampus, substantia nigra, and pyramidal. Conclusion The observations of the study suggest that Cordia dichotoma attenuated the haloperidol-induced neurological changes, indicating that the plant might benefit in the treatment of Parkinson's disease. The activity of Cordia dichotoma could be linked to its antioxidant property. Since, the drug is traditionally used in different parts of world; it could be a promising agent if more research establishes its safety and efficacy in other experimental models of Parkinson's Disease.

Abstract
This study was done to investigate the possible nephroprotective effect of an ethanolic root extract of Polyalthia Longifolia (PL) on vancomycin-induced nephrotoxicity using curative and protective models. Vancomycin (150 mg/kg, intravenous) was given to healthy Wistar albino rats in the curative model before the start of treatment, whereas the protective group received vancomycin at the conclusion of the 10-day treatment procedure. Animals were divided into six groups for both models; group I served as the normal control, while groups II, III, IV, V, and VI were kept as toxic control, standard (selenium, 6 mg/kg), LDPL (low dose of PL 200 mg/kg), HDPL (high dose of PL 400 mg/kg), and HDPL + selenium (interactive) groups, respectively. Renal biomarkers [(uric acid, creatinine, blood urea nitrogen (BUN), serum proteins], and blood electrolyte levels were measured for all tested groups. When compared to the vancomycin group, the HDPL significantly (p < 0.01) showed greater effectiveness in lowering the BUN, potassium, and calcium levels. Additionally, in the curative model, there was a significant (p < 0.05) decrease in the blood levels of uric acid, creatinine, BUN, potassium, and calcium in the animals who received the combination of selenium and HDPL. Both LDPL and HDPL did not provide any distinguishable effect in the protective model, but groups that received HDPL with selenium did provide detectable protection by significantly lowering their levels of uric acid, BUN, serum potassium, and total serum protein in comparison to the vancomycin control group. These findings indicate that, whether administered before or after renal damage is induced, the Polyalthia longifolia root extract provided only modest protection to nephrons, which require selenium support to prevent vancomycin-induced kidney damage.

Abstract
Sorghum is a major grain crop used in traditional meals and health drinks, and as an efficient fuel. However, its productivity, value, germination, and usability are affected by grain mold, which is a severe problem in sorghum production systems, which reduces the yield of harvested grains for consumer use. The organic approach to the management of the disease is essential and will increase consumer demand. Bioactive molecules like mVOC (volatile organic compound) identification are used to unravel the molecules responsible for antifungal activity. The Streptomyces rochei strain (ASH) has been reported to be a potential antagonist to many pathogens, with high levels of VOCs. The present study aimed to study the inhibitory effect of S. rochei on sorghum grain mold pathogens using a dual culture technique and via the production of microbial volatile organic compounds (mVOCs). mVOCs inhibited the mycelial growth of Fusarium moniliforme by 63.75 and Curvularia lunata by 68.52%. mVOCs suppressed mycelial growth and inhibited the production of spores by altering the structure of mycelia in tripartite plate assay. About 45 mVOCs were profiled when Streptomyces rochei interacted with these two pathogens. In the present study, several compounds were upregulated or downregulated by S. rochei, including 2-methyl-1-butanol, methanoazulene, and cedrene. S. rochei emitted novel terpenoid compounds with peak areas, such as myrcene (1.14%), cymene (6.41%), and ç-terpinene (7.32%) upon interaction with F. moniliforme and C. lunata. The peak area of some of the compounds, including furan 2-methyl (0.70%), benzene (1.84%), 1-butanol, 2-methyl-(8.25%), and myrcene (1.12)%, was increased during tripartite interaction with F. moniliforme and C. lunata, which resulted in furan 2-methyl (6.60%), benzene (4.43%), butanol, 2-methyl (18.67%), and myrcene (1.14%). These metabolites were implicated in the sesquiterpenoid and alkane biosynthetic pathways and the oxalic acid degradation pathway. The present study shows how S. rochei exhibits hyperparasitism, competition, and antibiosis via mVOCs. In addition to their antimicrobial functions, these metabolites could also enhance plant growth.

Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease involving multiple systems with a range of clinical presentations caused by the production of antibodies, activation of complements, and deposition of immune complexes. The exact cause of SLE is still unknown. The effectiveness of traditional treatment methods for SLE is very little. Nowadays, resistance to conventional therapy, steroids, and immunosuppressants is common among SLE patients. Patients with refractory disease and nephritis generally have severe drug-induced toxicity which contributes to organ dysfunction, despite available therapies. Different biologic agents and therapeutic antibodies have become an alternative and have been under experiment in clinical trials, enrolling patients whose disease is inadequately controlled by conventional treatment. Belimumab is the only targeted therapy approved for SLE treatment. This systematic review discusses one such biological agent for treating systemic lupus erythematosus, namely, belimumab. The systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies included randomized clinical trials (RCTs) from 2005 to 2021 on adult SLE. patients treated with monoclonal antibodies to assess the efficacy and safety. Methodological quality was assessed using PubMed, PMC, the Cochrane Risk of Bias tool, and the QUality In Prognosis Studies Tool (QUIPS) for RCTs. Two independent reviewers performed an electronic search on MEDLINE, Cochrane Library, SCIELO, Scopus, and ResearchGate. Based on a systematic review of articles we found that belimumab appears to be efficacious and generally well-tolerated in the treatment of SLE as compared to other drugs. The long-term use of belimumab combined with standard therapy showed a low incidence of organ damage. A lower incidence of organ damage was seen after initiating treatment in patients with a high risk for organ dysfunction. Patients who test for antinuclear antibody or anti-dsDNA-positive SLE, with moderate symptoms in the skin and musculoskeletal systems despite immunosuppressants, are treated with belimumab as an adjunct therapy. Patients with severe lupus nephritis or active CNS lupus cannot be treated with belimumab. Belimumab is effective in most races, as a clinical trial done in North-East Asia showed improvement in SLE symptoms and decreased dependence on prednisone. Belimumab also decreased disease activity and severe flares. Belimumab had greater efficacy in children.

Abstract
The current rapidly rising pandemic scenario due to the SARS COVID-19 infection is known to cause acute respiratory distress syndrome (ARDS) in severely ill patients. Meanwhile, many patients get to suffer multiple comorbidities like septicemia and acute kidney injury (AKI). Most of the critically ill mechanical ventilated patients are nowadays being given trials of prone ventilation for at least one-third duration of a day. These patients may require central venous catheter for various purposes such as fluid resuscitation, vasopressor administration, hemodialysis owing to the fact that many critically ill COVID-19 patients are going for AKI. Central venous access has a major role in accelerating the impending septicemia due to ARDS, by causing catheter-related bloodstream infection, thereby having a synergistic effect in causing sepsis. By using the unconventional methods which are used to give venous access, apart from the regularly used traditional methods of Internal Jugular, subclavian as well as femoral sites, this impending septicemia can be prevented or at least be hampered. This in turn will have major impact in the overall critically ill COVID-19-positive patient's outcome and will have a reduced mortality. How to cite this article: Muthukumar A.

Abstract
Damping-off of chilli caused by Pythium aphanidermatum is a major nursery disease in vegetables. In vitro experiments evaluated the effect of eight isolates of Trichoderma species (from chilli rhizosphere) were tested against P. aphanidermatum. All the Trichoderma species had varied antagonistic effects against the pathogen. Among them, TVC3 recorded maximum growth inhibition of P. aphanidermatum and produced more amounts of volatile and non-volatile metabolites. The culture filtrate of the Trichoderma isolate TVC3 recorded complete inhibition on the mycelial growth of pathogen at 15% concentration. Moreover, chilli seeds treated with culture filtrate of the isolate TVC3 recorded maximum germination percentage, shoot length, root length and vigour index of chilli. The study identified the Trichoderma isolate (TVC3) performed well in inhibiting the mycelial growth of pathogen as well as increased the plant growth in chilli.

We have previously shown that feeding a fish oil (FO) supplemented diet in combination with 40% food restriction (FO/FR) has a greater impact on extending life span in lupus-prone (NZB x NZW)F1 mice than either FO ad libitum (FO/AL) or corn oil food restricted (CO/FR) alone. Lupus disease is associated with increased Th-2 (i.e., IL-6 and IL-10) cytokine production and reduced IL-2 production and NF-kappaB activation. We hypothesized that the mechanism of action by which FO/FR increases life span may involve alterations in T-lymphocyte signaling and subsequent cytokine production. To test this hypothesis, we isolated and then stimulated splenic T-lymphocytes ex vivo with anti-CD3 and -CD28 monoclonal antibodies. We report here that CO/FR and FO/FR and to a lesser extent FO/AL offset disease-associated losses in Th-1 cytokine production, CD69 expression, and NF-kappaB activation in splenic T-lymphocytes activated ex vivo. Similarly, CO/FR and FO/FR prevented the disease-dependent rise in Th-2 cytokine production ex vivo and CD69 expression in vivo. In essence, the T-lymphocyte phenotype in the old CO/FR and FO/FR groups was identical to that in the young disease-free mice. Taken together, the data suggest that both CO/FR and FO/FR increase life span, in part, by maintaining a youthful immune phenotype in autoimmune-prone mice. However, FO/FR appears to represent a more potent dietary strategy in delaying disease-associated immune dysregulation than CO/FR.

Abstract
Moderate food and/or energy (calorie) restriction delays age-related immune dysfunction and prolongs life span in multiple animal models. The amount and type of dietary fatty acids can also profoundly affect life span. Marine-derived fish oils contain (n-3) fatty acids, which have potent anti-inflammatory properties. We therefore examined the influence of food restriction (40% overall reduction in intake of all dietary components) combined with substitution of fish oil for corn oil in a factorial design. Autoimmune-prone (NZB x NZW)F(1) (B/W) mice, which develop fatal autoimmune renal disease, were used. The food-restricted/fish oil diet maximally extended median life span to 645 d (vs. 494 d for the food-restricted corn oil diet). Similarly, fish oil prolonged life span in the ad libitum-fed mice to 345 d (vs. 242 for the ad libitum/corn oil diet). Increased life span was partially associated with decreased body weight, blunting renal proinflammatory cytokine (interferon-gamma, interleukins-10 and -12 and tumor necrosis factor-alpha) levels and lower nuclear factor-kappaB (NF-kappaB). Reductions in NF-kappaB were preceded by enhanced superoxide dismutase, catalase and glutathione peroxidase activities. These findings demonstrate the profound additive effects of food restriction and (n-3) fatty acids in prolonging life span in B/W mice. These observations may have additional implications in the management of obesity, diabetes, cancer and/or the aging process.

Abstract
Aquaporin-1(AQP1) and AQP2 are members of the aquaporin family of cell membrane water channel transport proteins and have been implicated in the regulation of renal water excretion. We have previously shown that calorie restriction (CR) relative to ad libitum (AL) feeding extends lifespan and delays the onset of autoimmune kidney disease in lupus-prone (NZBxNZW)F1 (B/W) mice. To determine if AQP1 and/or AQP2 expression is influenced by CR, mice were fed an AL or CR (40% less food) diet until 4 (young) or 9 (old) months of age when mice were sacrificed. Kidneys were removed and the expression of AQP1 and AQP2 was determined at the protein and mRNA levels using western blotting and RT-PCR respectively. While age did not significantly increase AQP1 expression in the AL groups, CR did increase both the protein (1.4-fold) and mRNA (2.4-fold) levels. In old mice, AQP1 expression was higher (1.8-fold) in CR compared to the AL group while CR had no effect in young mice. In contrast, AQP2 showed an age related decrease (55%) in the AL groups and an increase in the protein (8.4-fold) and mRNA (1.7-fold) levels in the CR groups. Relative to AL, CR decreased AQP2 expression at the protein (90%) and mRNA (50%) levels in the young mice while an increase at the protein (2.9-fold) and mRNA (1.9-fold) levels was evident in the old mice. Interestingly, a significant increase in water intake per gram body weight was found in both young and old CR fed mice when compared to their AL counterparts which may contribute to the prevention of autoimmune disease with age and differences in longevity. These data show, for the first time, significant age and diet influences in renal AQP1 and AQP2 expression at both protein and mRNA levels in lupus-prone mice.

Abstract
One-month-old male ICR mice were fed a nutritionally adequate, semipurified diet, either ad libitum (AL) or calorie restricted (CR) (40% less food) for 6 months and were killed to obtain spleens. Flow cytometric analysis revealed increased proportions of both CD4+ and CD8+ T cells in CR-fed mice compared to AL-fed mice. The T cell subsets of CR-fed mice were also found to have higher levels of plasma membrane Fas receptor expression. Similarly, Fas-ligand (Fas-L) expression was higher in anti-CD3-stimulated CD4+ and CD8+ T cells. CR-fed mice also had increased numbers of annexin V-positive CD4+ and CD8+ T cells in stimulated splenic lymphocytes suggesting an increased potential for apoptosis. Fas and Fas-L gene expression in splenic lymphocytes, which correlated closely with the observed increased rate of apoptosis, was significantly increased in CR-fed mice compared to AL-fed mice. In conclusion, these results indicate that CR increases the expression of Fas and Fas-L which may contribute to the known beneficial effects of CR such as prolongation of life span by activating chronic physiologically mediated apoptosis.

Abstract
An outbreak of acute hemorrhagic conjunctivitis occurred in Delhi, India, during August and September 1996. The etiologic agent was confirmed as enterovirus type 70 by a modified centrifugation-enhanced culture method followed by immunofluorescence and neutralization tests. After nearly a decade, this virus is reemerging as a cause of acute hemorrhagic conjunctivitis in India.

Abstract
Role of glutathione on kidney mitochondrial integrity and function during stone forming process in hyperoxaluric state was investigated in male albino rats of Wistar strain. Hyperoxaluria was induced by feeding ethylene glycol (EG) in drinking water. Glutathione was depleted by administering buthionine sulfoximine (BSO), a specific inhibitor of glutathione biosynthesis. Glutathione monoester (GME) was administered for supplementing glutathione. BSO treatment alone or along with EG, depleted mitochondrial GSH by 40% and 51% respectively. Concomitantly, there was remarkable elevation in lipid peroxidation and oxidation of protein thiols. Mitochondrial oxalate binding was enhanced by 74% and 129% in BSO and BSO + EG treatment. Comparatively, EG treatment produced only a 33% increase in mitochondrial oxalate binding. Significant alteration in calcium homeostasis was seen following BSO and BSO + EG treatment. This may be due to altered mitochondrial integrity and function as evidenced from decreased activities of mitochondrial inner membrane marker enzymes, succinate dehydrogenase and cytochrome-c-oxidase and respiratory control ratio and enhanced NADH oxidation by mitochondria in these two groups. NADH oxidation (r = -0.74) and oxalate deposition in the kidney (r = -0.70) correlated negatively with mitochondrial glutathione depletion. GME supplementation restored normal level of GSH and maintained mitochondrial integrity and function, as a result of which oxalate deposition was prevented despite hyperoxaluria. These results suggest that mitochondrial dysfunction resulting from GSH depletion could be a contributing factor in the development of calcium oxalate stones.

Abstract
The role of lipid peroxidation (LPO) in renal tubular damage mediated calcium oxalate retention was investigated in a rat model. Hyperoxaluria, without deposition of oxalate in kidney, was induced by administration of ethylene glycol (EG), a precursor of oxalate. Oxidative stress condition was produced by administration of buthionine sulfoximine (BSO), an inhibitor of glutathione biosynthesis. BSO-treated rats showed a significant (p < 0.001) increase in LPO over EG-treated rats and it was almost doubled in BSO + EG treated rats. LPO was accompanied by significant urinary excretion of renal damage marker enzymes such as gamma-glutamyl transpeptidase (gamma-GT), alkaline phosphatase (ALP) and cathepsin D, mucoproteins, and glycosaminoglycans (GAGs) in the BSO and BSO + EG groups but not in the EG group. Urinary excretion of gamma-GT (r = +0.90) (p < 0.001) and deposition of oxalate (r = +0.78) (p < 0.001) in kidney positively correlated with LPO. These results suggest that LPO initiates renal damage, thereby leading to calcium oxalate retention and stone formation.
