Through the Sands of Time: Evolutionary History and Systematics of the Awl‐Headed Snakes (Colubridae: Lytorhynchus) in the Saharo‐Sindian Region

open access: yesZoologica Scripta, EarlyView.
ABSTRACT The psammophilous colubrid genus Lytorhynchus is widely distributed in the deserts of the Saharo‐Sindian region and adjacent areas. The taxonomy of the genus and the number of recognised species have remained unstable since the last taxonomic revision in 1970, with differing views on the taxonomic status of L. gaddi and L. kennedyi.

Pro-Opiomelanocortin and Melanocortin Receptor 3 and 4 Mutations in Genetic Obesity

open access: yesBiomolecules
Genetic obesity results from loss-of-function mutations, including those affecting the leptin–melanocortin system, which regulates body weight. Pro-opiomelanocortin (POMC)-derived neurohormones act as ligands for melanocortin receptors (MCRs), regulating

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Modulation of social behavior by the agouti pigmentation gene

open access: yesFrontiers in Behavioral Neuroscience, 2014
Agouti is a secreted neuropeptide that acts as an endogenous antagonist of melanocortin receptors. Mice and rats lacking agouti (called non-agouti) have dark fur due to a disinhibition of melanocortin signaling and pigment deposition in the hair follicle.

Understanding the Molecular Processes of Obesity and the Anti‐Obesity Properties of Bioactive Substances Found in Tea

open access: yesPhytochemicals in Food and Medicine, Volume 1, Issue 3, September 2026.
ABSTRACT Obesity, a severe worldwide health concern, is characterized as an excessive deposit of fat in the human body. It has various ramifications that endanger human health and increase the financial expense. Obesity raises the risk of several illnesses, notably cardiovascular disease, NALFD, and diabetes, and has been associated with shorter ...

Molecular Mechanisms of Food Bioactive Constituents in the Management of Obesity and Hypertension: A Critical Review

open access: yesPhytochemicals in Food and Medicine, Volume 1, Issue 3, September 2026.
Obesity and hypertension co‐exist and share molecular mechanisms in terms of dietary therapy, modulated by food bioactive constituents. ABSTRACT Obesity and hypertension are among the most pressing global public health challenges. They frequently co‐exist, with obesity‐related hypertension accounting for an estimated 75% of the hypertension burden ...

Positioning Incretin‐Based and Next‐Generation Obesity Management Medications: A Methodological Framework for a Series of Systematic Reviews and Network Meta‐Analyses

open access: yesDiabetes, Obesity and Metabolism, Volume 28, Issue 9, Page 7768-7778, September 2026.
ABSTRACT Background The obesity pharmacotherapy landscape is evolving rapidly, with several approved incretin‐based therapies and an expanding pipeline of investigational compounds targeting multiple metabolic pathways. Conventional evidence syntheses often struggle to accommodate differences in dose selection, treatment duration and stage of clinical ...

Obesity Disrupts CtBP2‐Mediated Maintenance of Transcriptional Equilibrium in Hypothalamic Feeding Circuitry

open access: yesThe FASEB Journal, Volume 40, Issue 15, 15 August 2026.
CtBP2, a transcriptional corepressor with metabolite sensing capabilities, maintains feeding homeostasis by preventing excessive food intake in the hypothalamic feeding center. CtBP2 limits food intake by inhibiting KLF4 within AgRP neurons and by promoting the inhibitory influence of POMC neurons on AgRP neurons.
