Background: A cluster of metabolic indicators responsible to elevate the risk of high blood sugar, heart diseases along with stroke is called metabolic syndrome (MetS). Adipokines play critical roles in the formation and progression of these clusters of diseases. Adiponectin enhances fatty acid oxidation, prevents foam cell formation and improves lipid metabolism.

Aspherical surfaces, with their varying curvature, minimize aberrations and enhance clarity, making them essential in optics, aerospace, medical devices, and telecommunications. However, manufacturing these surfaces is challenging because of systematic errors in CNC equipment, tool wear, measurement inaccuracies, and environmental disturbances. These issues necessitate precise error compensation to achieve the desired surface shape.

New analogs of the PPAR pan agonist AL29-26 encompassed ligand (S)-7 showing potent activation of PPARα and -γ subtypes as a partial agonist. In vitro experiments and docking studies in the presence of PPAR antagonists were performed to help interpretation of biological data and investigate the main interactions at the binding sites. Further in vitro experiments showed that (S)-7 induced anti-steatotic effects and enhancement of the glucose uptake.

l-cysteine, a primary building block of mycothiol, plays an essential role in the defense mechanism of Mycobacterium tuberculosis (Mtb). However, it is unclear how Mtb regulates cysteine biosynthesis as no study has reported the cysteine regulatory complex (CRC) in Mtb. Serine acetyltransferase (SAT) and cysteine synthase (CS) interact to form CRC.

Fungal infections are becoming one of the most common diseases in recent years, especially when it comes about dealing skin infections. Different drugs are available commercially with antifungal activity for topical application and are effective for treatment of mild to moderate fungal infections. However they lack dermal bioavailability due to their poor penetrability, and less retention at the site thereby resulting in poor efficacy.

Bacterial blight (BB) is a devastating disease of rice in the tropics of Indian sub-continent, where the presence of races with varying levels of genetic diversity and virulence renders disease management extremely challenging. In this context, marker-assisted improvement of plant resistance has been proven as one of the most promising approaches for the development of sustainable rice cultivars. The present study demonstrates the marker-assisted introgression of the three BB resistant genes () into the background of HUR 917, a popular aromatic short grain (ASG) rice cultivar in India.

Article Synopsis
  • - A new series of derivatives of the PPARα/γ dual agonist LT175 was developed that effectively activates PPARα as a full agonist and PPARγ as a partial agonist.
  • - In vivo tests on diabetic mice showed that this compound reduced blood glucose and lipid levels without harming vital organs like bone, kidney, or liver.
  • - The compound also slightly inhibited the mitochondrial pyruvate carrier, showcasing a new mechanism for controlling blood sugar levels, making it a potential candidate for treating dyslipidemic type 2 diabetes.

We report a comparative study of a single plasma and a colliding laser produced plasma, investigated using a Faraday cup. An enhancement in ion emission and stagnation is observed in colliding plasma plume compared to single plasma plume. We observed that fast ion generation in laser ablated plasma can be achieved at large laser intensity on to the target.

Cysteine Synthase (CS), the enzyme that synthesizes cysteine, performs non-canonical regulatory roles by binding and modulating functions of disparate proteins. Beyond its role in catalysis and regulation in the cysteine biosynthesis pathway, it exerts its moonlighting effect by binding to few other proteins which possess a C-terminal "CS-binding motif", ending with a terminal ILE. Therefore, we hypothesized that CS might regulate many other disparate proteins with the "CS-binding motif".

Insulin resistance is a major pathophysiological feature in the development of type 2 diabetes (T2DM). Ferulic acid is known for attenuating the insulin resistance and reducing the blood glucose in T2DM rats. In this work, we designed and synthesized a library of new ferulic acid amides (FAA), which could be considered as ring opening derivatives of the antidiabetic PPARγ agonists Thiazolidinediones (TZDs).
