Article Synopsis
  • The study focuses on synthesizing non-toxic zinc oxide nanoparticles (ZnO NPs) from marine algae (Sargassum polycystum) due to concerns about their environmental impact and lack of regulation.* -
  • Characterization methods showed that these nanoparticles are rod-shaped with an average diameter of about 100 nm and exhibit specific crystal properties.* -
  • Toxicity tests using zebra fish larvae indicated that ZnO NPs caused developmental delays, increased deformities, oxidative stress, and changes in cellular activity, highlighting potential risks even with green synthesis methods.*

Background: Recently, green nanoparticles are gaining importance in drug development because of their lower toxicity, sustainability, cost effectiveness, simplicity, and ecofriendly nature compared with toxic chemicals.

Objective: In this study, we developed a nontoxic method for synthesizing iron oxide nanoparticles by using the fruit of Pouteria caimito that is rich in vitamin A and C and evaluated their cytotoxicity.

Methods: Pouteria caimito fruit¬-derived superparamagnetic nanoparticles (PCSNs) were characterized using physical and chemical methods, and their cytotoxicity was examined using the 3-(4, 5-dimethylthiazol-2-yl)-2-5-diphenyltetrazolium bromide (MTT) assay.

Article Synopsis
  • A study on male Wistar rats examined the impact of continuous light exposure (CL) and a western diet (WD) on the expression of Adropin, RORα, and Rev-erb-α, as well as energy balance over three months.
  • Findings revealed that CL alone boosted Adropin levels and gene expression, while WD and its combination with CL reversed these effects and altered gene expressions related to energy metabolism.
  • The combination of CL and WD not only increased total energy expenditure but also led to a reduction in food intake and multiple degenerative effects on liver, spleen, and kidney tissues, highlighting the negative implications for energy homeostasis.

Galangin is a natural compound with anticancer, anti-inflammatory, and antioxidant properties. However, the ameliorating effect of streptozotocin (STZ)-induced glucose homeostasis has not yet been evaluated. Hence, this study was aimed at exploring the role of galangin in STZ-induced glucose homeostasis, glycolytic and gluconeogenic enzyme changes in rats.

Background: Lavatera critica, a leafy green herb, is reported to have many pharmacological activities; but, the improvement of insulin sensitivity against the high gram-fat diet (HGFD)-caused insulin resistance (IR) has not yet been studied.

Objective: This study evaluated the role of Lavatera critica leaf extract (LCE) in systemic insulin resistance through the alleviation of adipose tissue inflammation and oxidative damage in HGFD fed mice.

Methods: The mice were fed with HGFD for 10 weeks and the diet was supplemented with LCE each day for the next five weeks.

Healthy plants and their constituents have been considered as a safe remedy for the treatment of obesity and obesity associated diseases. Herbacetin is a dietary flavonoid that has been explored for many pharmacological activities; but, the anti-hyperglycaemic and anti-hyperlipidemic properties of herbacetin have not yet been explored. The present study was performed to evaluate the ameliorative effect of herbacetin on high-fat diet-induced hyperglycaemia and hyperlipidemia in 57BL/6 J mice.

Background: Lipid accumulation is the most vital risk factor for inducing nonalcoholic fatty liver disease (NAFLD) and metabolic syndrome. Thus, the development of novel drugs is urgently needed to control obesity related diseases.

Objective: Here, we investigated the protective role of Lavatera critica (LC), a green vegetable, in male C57BL/6J mice fed with high fat (HF) diet for 10 weeks to induce hepatic lipid accumulation and oxidative cellular damage.

Objective: We designed this study to observe the effect of galangin on damaged mitochondria in the liver of diabetic rats.

Methods: Male albino Wistar rats were made diabetic by injecting streptozotocin (STZ) intraperitoneally (40 mg kg body weight (BW)). Galangin (8 mg kg BW) or glibenclamide (600 µg kg BW) was given orally daily once for 45 days to both healthy and diabetic rats.

Exposure to ultraviolet B (UVB; 280-320 nm) radiation induces the formation of reactive oxygen species (ROS) in the biological system. In this study, we examined the protective effect of carvacrol on UVB-induced lipid peroxidation and oxidative DNA damage with reference to alterations in cellular an-tioxidant status in human lymphocytes. A series of in vitro assays (hydroxyl radical, superoxide, nitric oxide, DPPH (2,2-Diphenyl-1-picryl hydrazyl), and ABTS (2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging assays) demonstrate antioxidant property of carvacrol in our study.

Obesity is the excessive fat accumulation in human body leading to increases a risk of various chronic diseases such as diabetes, cardiovascular diseases, cancer and osteoarthritis. Several flavonoids are known to have lipolytic activity influencing lipolysis and adipogenesis in adipose cells. To explore mechanism of the association of flavonoids in obesity and obesity associated protein (FTO), molecular docking studies were done for FTO with flavonoids, with orlistat (antiobesity drug) as a control.
