Summary Phototransduction is a light-stimulated process that heavily relies on continuous regeneration of 11-cis-retinal to keep rhodopsin function and adequate visual performance. Vitamin A is essential in this process, serving as a precursor of 11-cis-retinal. However, it is not naturally produced by the human body. A deficiency of this vitamin disrupts phototransduction and can lead to adverse… Read More Vitamin A Deficiency: Effects of Impaired Rhodopsin Regeneration on Photoreceptors
Puerto Rico’s emergency healthcare system suffers from critical deficiencies, including the absence of a fully accredited Level I trauma center, leaving over 3 million citizens vulnerable, particularly in rural areas. These systemic failures, exacerbated by colonial status, inadequate funding, and poor pediatric preparedness, necessitate urgent reforms to ensure equitable access and effective emergency response.… Read More When Seconds Count: Puerto Rico’s Ongoing Emergency Healthcare Crisis
Puberty is the developmental stage where sexual maturity and reproductive capacity are acquired, leading to the adult phenotype. The biological process of puberty involves a complex orchestration of hormonal signaling regulated by the hypothalamic-pituitary-gonadal (HPG) axis.
