High-Flow Congenital Arteriovenous Malformation of the Posterior Chest Wall in a Young Adult: A Case Report on a Rare Anomaly.

Arteriovenous malformations (AVMs) are rare congenital vascular anomalies characterized by direct connections between arteries and veins without intervening capillary beds, resulting in high-flow dynamics. While AVMs commonly affect the craniofacial region and extremities, involvement of the chest wall is exceedingly rare. We describe the case of a 19-year-old male patient who had a painless, progressively enlarging swelling in the right posterior chest wall that had been present since birth.

Cartap Poisoning with Paroxysmal Supraventricular Tachycardia: A Case Report.

Cartap, a nereistoxin derivative from the marine annelid Lumbriconeresis heteropoda, is widely used as a pesticide, targeting pests like caterpillars. While the WHO classifies it as moderately hazardous, with a recommended daily intake of 0.05 mg/kg, human toxicity reports are limited.

Vitamin D, Calbindin, and calcium signaling: Unraveling the Alzheimer's connection.

Calcium is a ubiquitous second messenger that is indispensable in regulating neurotransmission and memory formation. A precise intracellular calcium level is achieved through the concerted action of calcium channels, and calcium exerts its effect by binding to an array of calcium-binding proteins, including calmodulin (CAM), calcium-calmodulin complex-dependent protein kinase-II (CAMK-II), calbindin (CAL), and calcineurin (CAN). Calbindin orchestrates a plethora of signaling events that regulate synaptic transmission and depolarizing signals.
