PITX2 expression and Neanderthal introgression in HS3ST3A1 contribute to variation in tooth dimensions in modern humans.

Dental morphology varies greatly throughout evolution, including in the human lineage, but little is known about the biology of this variation. Here, we use multiomics analyses to examine the genetics of variation in tooth crown dimensions. In a human cohort with mixed continental ancestry, we detected genome-wide significant associations at 18 genome regions.

Assessment of reproductive, genotoxic, and cytotoxic effects of leachate-contaminated water in male mice.

Leachate-contaminated water (LCS) poses significant health risks due to its heavy metal content and altered physicochemical properties. This study examined the physicochemical parameters and heavy metal levels in LCS and assessed its reproductive toxicity, genotoxicity, and cytotoxic effects in exposed mice. Groups of mice (n = 5) were orally administered 100 μL of 30 % and 70 % LCS (v/v) twice daily for 35 days.

Randomised placebo-controlled trial of triclofos versus melatonin for sedating children undergoing sleep EEG.

Objective: To determine the efficacy of addition of melatonin or triclofos to sleep deprivation as compared with sleep deprivation with placebo for conduct of successful sleep electroencephalogram (EEG) among children between 6 months and 12 years of age.

Design, Setting And Patients: 486 children aged between 6 months and 12 years who were uncooperative or referred for sleep EEG were enrolled for this double-blind, placebo-controlled randomised trial between 30 June 2022 and 31 March 2023.

Intervention: On the day of sleep EEG, participants were sleep deprived by 25% of their regular sleep duration and then randomly assigned to receive either triclofos (50 mg/kg), melatonin (weight ≤15 kg=3 mg; weight >15 kg=6 mg) or placebo.

Colonic actinomycosis masquerading a cancer resulting complete bowel obstruction-a case report.

Introduction: Colonic actinomycosis is an uncommon chronic infection associated with granulomatous inflammation resulting multiple abscesses and sinuses. Common modes of presentation include weight loss, malaise, abdominal pain, and abdominal mass, which might mimic neoplasia.

Case Presentation: A 60-year-old female presented with painful lump in right iliac fossa (RIF) for 3 weeks and acute complete bowel obstruction for 3 days.
