Diabetes mellitus (DM) and its complications are a severe public health concern due to the high incidence, morbidity, and mortality rates. The present study aims to synthesize and characterize silver nanoparticles (AgNPs) using the aqueous leaf extract of Psidium guajava (PGE) for investigating its antidiabetic activity. Psidium guajava silver nanoparticles (PGAg NPs) were prepared and characterized by various parameters. The in vivo study was conducted using PGE and PGAg NPs in Streptozotocin (STZ)-induced diabetic rats to assess their antidiabetic properties. STZ of 55 mg/kg was injected to induce diabetes. The PGE, PGAg NPs at a dose of 200 and 400 mg/kg and standard drug Metformin (100 mg/kg) were administered daily to diabetic rats for 21 days through the oral route. Blood glucose level, body weight changes, lipid profiles, and histopathology of the rats’ liver and pancreas were examined. In the diabetic rats, PGE and PGAg NPs produced a drastic decrease in the blood glucose level, preventing subsequent weight loss and ameliorating lipid profile parameters. The histopathological findings revealed the improvements in pancreas and liver cells due to the repercussion of PGE and PGAg NPs. A compelling effect was observed in all doses of PGE and PGAg NPs; however, PGAg NPs exhibited a more promising result. Thus, from the results, it is concluded that the synthesized PGAg NPs has potent antidiabetic activity due to its enhanced surface area and smaller particle size of nanoparticles.

Herein, zinc oxide nanoparticles (ZnO NPs) were greenly synthesized from Tridax procumbens aqueous leaf extract (TPE) and characterized physically (e.g., Fourier-transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM)) and biologically (test of their anti-diabetic activity). Anti-diabetic activities of TPE and TPE-derived ZnO NPs have been carried out in a streptozotocin (STZ)—induced diabetic rat model. Diabetes mellitus (DM) was induced with a single intraperitoneal dosage of the glucose analogue STZ (55 mg/Kg) known to be particularly toxic to pancreatic insulin-producing beta-cells. TPE and TPE-derived ZnO NPs were administered orally, once every day for 21 days in diabetic rats, at 100 and 200 mg/Kg, respectively. The standard antidiabetic medication, glibenclamide, was used as a control at a dose of 10 mg/Kg. Various parameters were investigated, including bodyweight (bw) variations, glycemia, lipidaemia, glycated hemoglobin (HbA1c), and histopathological alterations in the rat’s liver and pancreas. The TPE-mediated NPs were small, spherical, stable, and uniform. Compared to TPE and, to a lesser extent, glibenclamide, TPE-derived ZnO NPs lowered blood glucose levels considerably (p < 0.05) and in a dose-dependent manner while preventing body weight loss. Further, positive benefits for both the lipid profile and glycated hemoglobin were also noticed with TPE-derived ZnO NPs. The histopathological assessment revealed that synthesized TPE-derived ZnO NPs are safe, non-toxic, and biocompatible. At 200 mg/Kg/day, TPE-derived ZnO NPs had a more substantial hypoglycemic response than at 100 mg/Kg/day. Thus, in this first reported experimental setting, ZnO NPs biosynthesized from the leaf extract of Tridax procumbens exert more potent anti-diabetic activity than TPE and glibenclamide. We conclude that such a greenly prepared nanomaterial may be a promising alternative or complementary (adjuvant) therapy, at least to the current Indian’s traditional medicine system. Translational findings are prompted in human populations to determine the efficacy of these NPs.

Polyherbal formulation (PHF) enhances therapeutic efficacy and minimizes side effects by reducing individual herb dosages. Allopolyherbal formulation (APHF) combines polyherbal extracts with allopathic medication, effectively reducing the latter’s required dose and mitigating associated adverse effects. The current study intends to assess the anti-diabetic effects of PHF and APHF in-vivo. Dried raw powders of Cassia auriculata leaf, Centella asiatica leaf, and Zingiber officinale rhizome were extracted by cold maceration process using 70% ethanol. These extracts were combined in three different ratios to make PHF. PHF was subjected to qualitative and quantitative phytochemical investigations. APHF has been prepared by combining a potent ratio of PHF with metformin in three different ratios. The compatibility of APHF has been confirmed by differential scanning calorimetry (DSC). In vivo activity was also evaluated in streptozotocin-induced diabetic albino rats. PHF (3 different ratios at a dose of 200–400 mg/kg b.w), APHF (combination of PHF and metformin in 3 different ratios, 200 + 22.5, 200 + 45, and 200 + 67.5 mg/kg b.w), and metformin (90 mg/kg b.w) were administered to albino rats for 21 consecutive days. Blood glucose levels were estimated on the 1st, 7th, 14th, and 21st days of treatment. On the 21st day, blood was collected by cardiac puncture for biochemical analysis. The liver and pancreas were isolated and subjected to histopathological analysis. PHF and APHF showed significant anti-diabetic and antihyperlipidemic efficacy. In comparison to PHF, APHF had the most promising action. The current study demonstrated that PHF and APHF are safe and efficacious drugs in the treatment of diabetes mellitus as they help to replace or lower the dose of metformin, thereby decreasing the risks of metformin.

Post-COVID-19 pandemic, individuals are experiencing various forms of stress. This study assessed the prevalence of stress among Indian adults, examined its physical and psychological impacts, and investigated stress management strategies, aiming to fill existing gaps in research. This retrospective observational study utilized an online survey from March 16, 2023, to July 30, 2023, using snowball sampling to target the Indian population. Respondents aged ≥18 years participated in the study. The survey collected data on demographic information, self-reported stress levels, and Perceived Stress Scale (PSS) scores. The chi-square test was applied for statistical analysis, and results with a p-value under 0.05 were considered significant. Among 1,479 respondents (638 males, 841 females; mean age: 23.7±7.7 years), 76.0% of respondents resided in Karnataka. Out of 1,479 respondents, 9.6% experienced mild stress, 84.9% experienced moderate stress, and 5.5% experienced severe stress according to the PSS. Females experienced significantly higher stress levels when compared with males (p=0.047), but both experienced moderate stress levels. Financial problems (20.7%) and studies (36.4%) were the most common stressors among respondents. They most frequently manage stress through personal strategies, such as sleeping and listening to music. The present study's findings indicate that, following the COVID-19 health crisis, moderate levels of stress are significantly prevalent in the Indian population, primarily due to academic and job-related pressures.

Background Plectranthus amboinicus (Lour.) Spreng, a member of the Lamiaceae family, is commonly utilized in both traditional medicine and culinary applications. This research focuses on optimizing the pharmacodynamic and pharmacokinetic characteristics of Plectranthus amboinicus by developing and assessing a nanoparticle formulation combined with gelatin.

The resulting nanoparticles were roughly 250 nm in diameter and exhibited a spherical morphology. Toxicity tests were conducted at concentrations up to 1000 μg/mL. The potential antidiabetic effects were evaluated by measuring glucose uptake in 3T3-L1 adipocytes and L6 myoblast cells. Results The gelatin-conjugated nanoparticles of Plectranthus amboinicus were non-toxic at concentrations up to 1000 μg/mL. They significantly improved glucose uptake in L6 myoblast cells, indicating better glucose metabolism. Additionally, the formulation showed promise in decreasing fat accumulation and carbohydrate digestion, implying significant antidiabetic effects.
