Computed tomographic (CT) findings of the urinary tract and adrenal glands of five healthy male calves in the first 105 days of life were compared with corresponding cadaver slices. The structures seen on CT images were identified using the corresponding cadaver slices. CT produced exact images of the kidneys, urinary bladder, urethra and adrenal glands, but reliable images of the ureters were only obtained near the renal hilus. There was excellent agreement between the structures on the CT images and the tissue slices. The structure and vessels of the kidneys, the origin of the ureters, the location, size and content of the urinary bladder and the course of the urethra in the pelvis and penis were evident on images. The size and volume of the kidneys and the length and width of the adrenal glands increased significantly during the study, but the ureteral and urethral diameters changed little.

The pathogenesis of long COVID (LC) still presents many areas of uncertainty. This leads to difficulties in finding an effective specific therapy. We hypothesize that the key to LC pathogenesis lies in the presence of chronic functional damage to the main anti-inflammatory mechanisms of our body: the three reflexes mediated by the vagus nerve, the hypothalamic-pituitary-adrenal (HPA) hormonal axis, and the mitochondrial redox status.

Background: Multiple endocrine neoplasia type 1 (MEN1) is a rare autosomal dominant disorder, accompanied by multiple endocrine neoplasms of the parathyroid, pancreas, pituitary, and other neoplasms in the adrenal glands. However, in some cases, patients clinically diagnosed with MEN1 may be genotype-negative.
Case Presentation: A 56-year-old female was diagnosed with MEN1 based on a macroprolactinoma (19 mm in diameter), primary hyperparathyroidism, and a cortisol-producing adrenal adenoma, without a family history.

Chronic elevated blood pressure impinges on the functioning of multiple organs and therefore harms body homeostasis. Elucidating the protective mechanisms whereby the organism copes with sustained or repetitive blood pressure rises is therefore a topical challenge. Here we address this issue in the adrenal medulla, the master neuroendocrine tissue involved in the secretion of catecholamines, influential hormones in blood pressure regulation.

Aldosterone-producing adenoma (APA) is a leading cause of primary aldosteronism (PA), a condition marked by excessive aldosterone secretion. CYP11B2, the aldosterone synthase, plays a critical role in aldosterone biosynthesis and the development of APA. Despite its significance, encoding regulatory mechanisms governing CYP11B2, particularly its degradation, remain poorly understood.

Neuroblastoma is a rare tumour originating from neural crest cells, primarily occurring in the adrenal glands and sympathetic ganglia, with prenatal diagnosis often complicated by the difficulty in distinguishing it from other foetal abdominal or paraspinal masses. We present a case of foetal neuroblastoma in a 26-year old woman who, at 36 weeks of gestation, experienced absent foetal movements, leading to ultrasound confirmation of foetal demise with associated effusions. An emergency caesarean section revealed a stillborn male foetus with a previously undetected encapsulated mass in the posterior mediastinum, which was confirmed as neuroblastoma through histopathological analysis.
