The ultrastructural study of adrenal cortex from Plasmodium berghei infected mice showed different degrees of capillary wall alterations including disruption and widening of the fenestrae, capillaries packed with parasitized erythrocytes, necrosis of cortical cells, parasitized erythrocytes outside capillaries and in some instances inside cortical cell cytoplasm. Lymphocytes were also observed in degenerated cortical cells. Our results suggest that adrenal cortex lesions may be relevant in the etiopathogenesis of severe malaria.

Behçet's disease (BD) is a rare systemic vasculitis that is characterized by recurrent oral and genital ulcers, uveitis, and skin lesions. Although neurological involvement is a known complication, ischemic stroke remains uncommon. Herein, we report a 37-year-old Kuwaiti woman who experienced recurrent ischemic stroke with no traditional risk factors.

The zona glomerulosa (ZG) synthesizes the mineralocorticoid aldosterone. The primary role of aldosterone is the maintenance of volume and electrolyte homeostasis. Aldosterone synthesis is primarily regulated via tightly controlled oscillations in intracellular calcium levels in response to stimulation.

Background: Medical Expulsive Therapy (MET) has been recommended as an established modality for the treatment of distal ureteral stones due to its clearance rate, pain control, and patient satisfaction while having minimal morbidity in comparison to other urologic interventions. In some studies, a combination of medications has been used, which we assessed in this network meta-analysis (NMA).
Methods: We conducted systematic searches in PubMed, Scopus, and Web of Science to identify relevant trials published between 2001 and 2024.

Stress is linked to oxidative imbalance, neuroendocrine system malfunction, and cognitive dysfunction. It is a recognized cause of neuropsychiatric diseases. Natural flavonoid apigenin (API) has neuroprotective and antidepressant properties, but little is known about its potential in restoring memory function under stress-related circumstances.

Background: Adrenocortical carcinoma (ACC) is a rare, aggressive malignancy with high recurrence rates and poor prognosis. Current prognostic models are inadequate, highlighting the need for innovative diagnostic tools. Pathomics, which utilizes computer algorithms to analyze whole-slide images, offers a promising approach to enhance prognostic models for ACC.
