Combinations of three molecular markers (alpha-fetoprotein, ligandin and A-protein) were investigated in individual cells of the rat hepatocellular tumours by means of indirect immunofluorescence. It was found that each subtype of trabecular carcinoma classified on the basis of cytomorphological appearance as well, moderately, and poorly differentiated hepatomas, exhibited its characteristic combination(s) of the molecular markers studied. Each marker pattern observed in the tumours had its counterpart in the marker combination specific to one of the stages of normal liver tissue differentiation. Thus immunomorphological examination of protein marker combinations in hepatocellular carcinomas allowed the authors to propose an objective classification of these tumours according to their level of differentiation.

The tRNA-derived small RNAs (tsRNAs) are a new class of non coding RNAs, which are stable in body fluids and can be used as potential biomarkers for disease diagnosis. However, the exact value of tsRNAs in the diagnosis of tuberculosis (TB) is still unclear. The objective of the present study was to evaluate the performance of the serum tsRNAs biosignature to distinguish between active TB, healthy controls, latent TB infection, and other respiratory diseases.

Background: Varicocele (Vx) which is the most treatable cause of male infertility, is also associated with low sperm count, decreased sperm motility and increased sperm abnormal morphology. We aimed in the current study to evaluate the correlation between seminal α-Glycerylphosphorylcholine (αGPC) and semen parameters in infertile patients pre- and post- sub-inguinal micro-varicocelectomy.
Methods: The current comparative prospective study was carried out on 20 male patients who presented to Kasr Al-Ainy Hospitals from March 2022 to March 2023 as well as 20 healthy controls.

Background: Immunoglobulin G4-related disease (IgG4-RD) is an immune-mediated fibrous inflammatory disease. Recently, an association between IgG4-RD and tuberculosis (TB) has been reported.
Case Summary: We report a 56-year-old man complaining of a cough and poor appetite for 2 months and oliguria for 1 day.

Background: The differential diagnosis between benign and malignant thyroid nodules continues to be a major challenge in clinical practice. The rising incidence of thyroid neoplasm and the low incidence of aggressive thyroid carcinoma, urges the exploration of strategies to improve the diagnostic accuracy in a pre-surgical phase, particularly for indeterminate nodules, and to prevent unnecessary surgeries. Only in 2022, the 5th WHO Classification of Endocrine and Neuroendocrine Tumors, and in 2023, the 3rd Bethesda System for Reporting Thyroid Cytopathology and the European Thyroid Association included biomarkers in their guidelines.

Copy number variations of the human gene, resulting from megabase-scale microdeletions or microduplications in the 3p26.3 region, are frequently implicated in neurodevelopmental disorders such as intellectual disability and developmental delay. However, duplication of the full-length human gene presents with variable penetrance, resulting in phenotypes that range from neurodevelopmental disorders to no visible pathologies, even within the same family.
