Neuroendocrine tumors (NETs) are commonly located in the respiratory and gastrointestinal tract; however, these tumors can rarely be found in the urinary bladder. NETs comprise <1% of all bladder tumors; usually intermixed with urothelial carcinoma and its variants. We report a case of primary neuroendocrine carcinoma of urinary bladder in an adult female with a history of smoking and hematuria. The present case highlights the importance of immunohistochemistry in arriving at an accurate diagnosis and thereby differentiating this tumor from other clinical mimics.

In homeostasis, which plays an important role in the proper functioning and maintenance of the internal functioning of the body, kidneys play a key role in being responsible for the proper homeostasis of glucose. Among glucose transporters, sodium-dependent glucose co-transporters (SGLTs) have a major role in the kidney's ability to reabsorb glucose. Although the localization of these transporters has been extensively studied in mammals, there are still gaps in knowledge of the localization of SGLTs in birds of different age groups.

Background: Endometriosis patients exhibit a cancer-like glycolytic phenotype. The pyruvate kinase M2 (PKM2)/hypoxia-inducible factor-1 alpha (HIF-1α) axis plays important roles in glycolysis-related diseases, but its role in patients with endometrial polyps (EPs) combined with endometriosis has not been validated.
Methods: EP samples were collected from patients with and without endometriosis.

Background: Mucopolysaccharidosis (MPS) is a class of hereditary metabolic diseases that demonstrate itself by accumulating incompletely degraded glycosaminoglycans (GAGs). MPS are classified according to the kind(s) of stored GAG(s) and specific genetic/enzymatic defects. Despite the accumulation of the same type of GAG, two MPS diseases, Sanfilippo (MPS III) and Morquio (MPS IV), are further distinguished into subclasses based on different enzymes that are deficient.

Background: K48-linked ubiquitin chain (Ub-K48) is a crucial ubiquitin chain implicated in protein degradation within the ubiquitin-proteasome system. However, the precise function and molecular mechanism underlying the role of Ub-K48 in the pathogenesis of Alzheimer's disease (AD) and neuronal cell abnormalities remain unclear. The objective of this study was to examine the function of K48 ubiquitination in the etiology of AD, and its associated mechanism of neuronal apoptosis.

Prostate cancer is the most common noncutaneous malignancy among men worldwide, including in Sudan, where it represents a significant public health challenge. CD147, a transmembrane glycoprotein implicated in tumor progression, invasion, and metastasis, has shown potential as a prognostic biomarker in various cancers. This retrospective case-control study aimed to evaluate CD147 expression in prostate adenocarcinoma among Sudanese men and its association with tumor grade.
