microRNA and Regulatory Networks of Human Macrophage During Leishmania major In Vitro Infection

Leishmania (L.) major modulates host microRNA (miR) expression to promote intracellular survival, yet the roles of specific miRs during early infection of human macrophages remain poorly defined. We investigated the dynamic regulation of miR-21-5p and miR-146a-5p in THP-1-derived...

Evidence-Tiered Venomics of the BotG50 Toxic Fraction from Buthus tunetanus Reveals a Diversified Neurotoxin Repertoire

Scorpion venoms represent complex pharmacological arsenals whose complete molecular inventory remains incompletely defined, particularly for North African buthid species of high medical relevance. Buthus tunetanus is among the most clinically significant scorpion species across t...

Neuropsychiatry genetics in Africa

Across Africa, rising mental health needs coincide with rapid advances in genomics, digital health and continental policy reform. Yet research into the genetic, environmental and social determinants of neuropsychiatric illness remains sparse and underfunded. This review argues th...

Hypokalemia leading to the diagnosis of primary Sjögren’s syndrome: the role of early renal biopsy

Abstract Background Hypokalemia due to distal renal tubular acidosis (dRTA) may represent the earliest manifestation of primary Sjögren’s syndrome (pSS), preceding the recognition of sicca symptoms. We report a case series highlighting the diagnostic challenges, renal manifestati...

Contribution of a combined approach using refined enterotyping and non-negative matrix factorization (NMF) to the characterization of the gut microbiota in Tunisia, North Africa

Abstract This pilot study aimed to assess the enhanced capabilities of a combined approach using refined enterotyping and non-negative matrix factorization (NMF) for identifying specific microbiota patterns in healthy adults in Tunisia. Shotgun metagenomic sequencing was performe...

Gut Microbiota Signatures and Ecological Network Alterations Associated with Hemodialysis

Hemodialysis (HD) is the most widely used renal replacement therapy for patients with end-stage renal disease (ESRD) and is frequently accompanied by long-term complications that impair quality of life, including metabolic and inflammatory disturbances. Growing evidence suggests...

N-Acetylcysteine, Tiron, and Their Combination: In Vitro Antioxidant and Anti-Inflammatory Activities and Their Protective Effect in a Rat Model of Acetic Acid-Induced Ulcerative Colitis

Ulcerative colitis is characterized by inflammation, oxidative stress, and excessive free radical production. This study investigated the antioxidant, anti-inflammatory, and protective effects of N-acetylcysteine (NAC), Tiron, and their fixed-ratio combination in acetic acid-indu...

Building a genomics-capable cancer workforce: a competency-based framework for education and training in precision oncology

Background The Lancet Oncology Commission on cancer genomics and precision oncology identified workforce capability, education, and training as major constraints to equitable implementation. As genomic and multi-omic technologies become integrated into cancer care, structured app...
