Diabetic chronic wounds and amputations are very serious complications of diabetes mellitus (DM) that result from an integration factor, including oxygen deprivation, elevated reactive oxygen species (ROS), reduced angiogenesis, and microbial invasion. These causative factors lead to tenacious wounds in an inflammatory state, which eventually results in tissue aging and necrosis. Wound healing in DM potentially targets C-X-C chemokine receptor type 4 (CXCR4) regulates several signalling pathways.

The Wnt/β-Catenin pathway (Wnt/β-CatP) is implicated in accelerating carcinogenesis and cancer progression, contributing to increased morbidity and treatment resistance. Even though it holds promise as a focus for cancer treatment, its intricate nature and diverse physiological effects pose significant challenges. Recent years have witnessed significant advancements in this domain, with numerous natural products demonstrating promising preclinical anti-tumor effects and identified as inhibitors of the Wnt/β-CatP through various upstream and downstream mechanisms.

Overproduction of reactive nitrogen and oxygen species (RNS and ROS) has been linked to the pathogenesis of diabetes, hypertension, hyperlipidemia, stroke, angina, and other cardiovascular diseases. These species are produced in part by the mitochondrial respiratory chain, NADPH oxidase, and xanthine oxidase. RNS and ROS both contribute to oxidative stress, which is necessary for the development of cardiovascular disorders.

Article Synopsis
  • - MAFLD (Metabolic Associated Fatty Liver Disorder) affects about 1/3 of the global population and is often linked to conditions like type 2 diabetes, metabolic syndrome, and obesity, which increase vulnerability to COVID-19 infections.
  • - Patients with MAFLD have a higher risk of severe COVID-19 outcomes due to pre-existing metabolic issues, with studies showing they're 4 to 6 times more susceptible to infections and complications.
  • - The review examines how MAFLD can worsen liver function and overall health in COVID-19 patients, highlighting mechanisms such as liver injury and compromised immunity that lead to increased morbidity and risk of ICU admission.

The current work was designed to study the starch's physicochemical attributes, tablet disintegration and dissolution efficiency and its derivatives obtained from the glutinous Assam bora rice (G-ABR) variety of Assam, Northeast India. Starch was isolated by a simple protein denaturation method, and a starch derivative was prepared through citric acid modification. G-ABRS and citrated G-ABRS were characterized through FTIR, DSC, XRD and SEM.

Maxillary hypoplasia is often evident in cleft patients due to impaired growth and dense scarring from previous cleft surgeries. For these patients, treatment scenario has taken many turns over ages, evolved from orthognathic correction to distraction osteogenesis, with mixed prognosis and outcome depending on severity of the case and other several factors. We are reporting a case of 24-year-old female with maxillary hypoplasia secondary to bilateral cleft lip and palate with hypoplastic prolabium, who has been treated with two patient-specific implants in bilateral maxillary region for facial profile enhancement.

A formal synthesis of the antiasthma drug montelukast sodium is described, wherein the key chiral diol intermediate was accessed with greater convergence of the C-C bond-forming steps as compared to previous routes. Improved synthetic efficiency was achieved by deploying homogeneous metal-based catalysis in two pivotal steps. In the first, a tandem Mizoroki-Heck reaction and double-bond isomerization between a previously known allyl alcohol intermediate and a hindered 2-(2-halophenyl)propan-2-ol secured direct access to the 3-(2-(2-hydroxypropan-2-yl)phenyl)-1-phenylpropan-1-one moiety in the product.
