Abstract:
A 30-year-old male with bilateral acute visual loss presented with retinal edema in the posterior pole and peripapillary region with extensive retinal hemorrhages. Fluorescein angiography revealed delayed arterial filling in the right eye and absent arterial filling in the left eye, suggesting bilateral central retinal artery occlusion. Systemic evaluation revealed a history of chronic low-grade fever and generalized lymphadenopathy. HIV (ELISA) was positive, and other systemic comorbidities were ruled out. Cervical lymph node biopsy stained positive for acid-fast bacilli, with large areas of necrosis, palisaded by epithelioid cell granulomas, macrophages, and multinucleated giant cells, suggesting lymph node tuberculosis. Despite antiretroviral and antitubercular therapy, he developed optic atrophy at 4 weeks.

RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...
