Introduction: Low back pain is common during pregnancy, affecting up to 76% of women. However, symptomatic lumbar disc herniation (LDH) is rare, occurring in about 1 in 10,000 pregnancies, with less than 2% progressing to cauda equina syndrome (CES). The overlap in symptoms between LDH and typical pregnancy-related conditions complicates both diagnosis and management.

Drought stress (DS) adversely affects a plant's development and growth by negatively altering the plant's physio-biochemical functions. Previous investigations have illustrated that seed priming with growth regulators is an accessible, affordable, and effective practice to elevate a plant's tolerance to drought stress. Melatonin (MT) is derived from the precursor tryptophan and can improve germination, biomass, and photosynthesis under stress conditions.

Liver ischemia-reperfusion (I/R) injury is a common cause of organ failure, developed by a sudden block in the blood and oxygen supply and subsequent restoration. I/R damage is responsible for acute and chronic rejection after organ transplantation, accounting for 10% of early graft failure. The study investigated the therapeutic properties of fangchinoline in liver injury-induced rats.

Background: Gliomas represent the most common primary intraparenchymal brain tumors in adult and pediatric patients. Neuropathological work-up of these gliomas typically entails the determination of isocitrate dehydrogenase (IDH) mutational status, presence or absence of 1p/19q co-deletion, and O6 methylguanine-DNA methyl-transferase (MGMT) promoter methylation status.

Case Description: We present here an unusual case of a posterior fossa tumor in a 51-year-old female, which was initially diagnosed as astrocytoma with some high-grade features that recurred, displaying even more aggressive features such as infiltration and increased proliferative activity.

Introduction Epistaxis, or nosebleeds, is a common pediatric emergency, impacting their quality of life (QoL). Existing research on epistaxis has predominantly focused on clinical aspects, overlooking its broader impact on the quality of life of affected children and the functioning of their families. This study seeks to fill that gap by assessing the impact of recurrent epistaxis on children's QoL, family dynamics, and parental stress in Saudi Arabia's Eastern region.
