An observation of granular cell Abrikosov tumor metastasizing into lymph nodes is presented. The diagnosis was confirmed by electron microscopy. The ultrastructural features of the tumor confirming its neurogenic origin are described. This is indicated, in particular, by the similarity of the tumor cells with lemmocytes, detection of a basal membrane in some of them, as well as the presence of axonlike projections. The content of some cytoplasmic inclusions was found to be an accumulation of microtubules.

Bisphenol A (BPA) is a hazardous endocrine disruptor released into the environment during the production of certain plastics used for covering of food and beverage cans. In this work, we examined the protective benefits of selenium (Se) against intestinal damage induced by BPA in male rats. Rats were distributed randomly into four groups.

During routine sampling of northern pike, a male with circular blue-metallic granular spots mainly located on the head and back was identified. Histological investigations presented multifocally thickened epidermis rich in basophilic large structures with a granulated rim and a dense, non-granulated center. Other organs showed no signs of infection.

(Lepidoptera: Nolidae) is a major pest of cotton and other crops in Egypt, and the widespread use of insecticides has led to resistance. This study evaluates, for the first time, the bioactivity of (Malpighiales: Euphorbiaceae) oil and its nano-emulsion (CTNE) against 25 newly hatched larvae of Boisd. We assessed their biological effects across different developmental stages and performed histological and ultrastructural examinations.

: Focal segmental glomerulosclerosis (FSGS) is a pattern of kidney injury with diverse causes and pathogeneses, resulting in podocyte injury and depletion. It can be classified as primary, genetic, or secondary. Because FSGS classically has a worse prognosis in patients with nephrotic syndrome, most studies have focused on the treatment and evolution of these patients, resulting in a lack of data related to patients without nephrotic syndrome.

There is an emerging wide use of nanotechnology in the medical fields. The information regarding distribution and clearance of gold nanoparticles (AuNPs) in the ocular tissue is insufficient. We investigated the cumulative effect of AuNPs on rat lens structure and their effect on the redox state and aquaporin-0 (AQP0) expression.
