A rare presentation of neurofibromatosis mimicking leprosy.

Neurofibromatosis type 1 (NF-1) is a genetic disorder commonly characterized by café-au-lait macules, neurofibromas and axillary freckling. We present the case of a 20-year-old female who had bilateral neck swellings, and these swellings were misdiagnosed as cervical lymphadenopathy, and the patient was started on anti-tubercular therapy (ATT), but the swellings didn't show any improvement despite 6 months of ATT. Further examination revealed thickening of the greater auricular, supratrochlear and supraorbital nerves, accompanied by an unusual freckling pattern along the thickened nerves, which were suggestive of neurofibromatosis.

Withaferin A inhibits Chikungunya virus nsP2 protease and shows antiviral activity in the cell culture and mouse model of virus infection.

Chikungunya virus (CHIKV) is a mosquito-transmitted alphavirus causing fever, myalgia, and debilitating joint swelling and pain, which in many patients becomes chronic. The frequent epidemics of CHIKV across the world pose a significant public health burden necessitating the development of effective antiviral therapeutics. A cellular imaging-based high-content screening of natural compounds identified withaferin A (WFA), a steroidal lactone isolated from the plant Withania somnifera, as a potent antiviral against CHIKV.

Evaluation of health-related quality of life and adherence among pre-extensively drug-resistant tuberculosis patients receiving either Bedaquiline or Delamanid regimen at a teaching hospital in Eastern India.

Background: The foremost concern and challenge in managing drug-resistant tuberculosis is ensuring a high health-related quality of life (HRQoL). The effectiveness of pre-extensively drug-resistant (Pre-XDR) tuberculosis management hinges on patients adhering to therapy, a crucial factor in averting the development of drug-resistant strains, ultimately enhancing HRQoL.

Methodology: This analytical longitudinal study spanned two years at a teaching hospital and involved collaboration between the Departments of Pharmacology and Pulmonary Medicine.

Burden and Risk Factors of Occupational Noise-Induced Hearing Loss Among Employees Working at an International Airport in Eastern India.

Background: Occupational noise-induced hearing loss (ONIHL) is the commonest occupational disease globally. However, literature on ONIHL in airport employees of developing countries is scarce.

Aims: To assess the burden of ONIHL and its associated factors among employees working at an international airport in Eastern India.

Determinants of chemoselectivity in ubiquitination by the J2 family of ubiquitin-conjugating enzymes.

Ubiquitin-conjugating enzymes (E2) play a crucial role in the attachment of ubiquitin to proteins. Together with ubiquitin ligases (E3), they catalyze the transfer of ubiquitin (Ub) onto lysines with high chemoselectivity. A subfamily of E2s, including yeast Ubc6 and human Ube2J2, also mediates noncanonical modification of serines, but the structural determinants for this chemical versatility remain unknown.
