Pathology News and Research

RSS

Pathology is the study and diagnosis of disease through examination of organs, tissues, bodily fluids, and whole bodies (autopsies). The term also encompasses the related scientific study of disease processes, called General pathology. Medical pathology is divided in two main branches, Anatomical pathology and Clinical pathology. Veterinary pathology is concerned with animal disease whereas Phytopathology is the study of plant diseases.

Study Shows How Genetic Variations Can Enhance Cancer Drug Effectiveness

APOE4 and Microglia Together Drive Alzheimer's Protein Deposits

In healthy brains, immune cells called microglia patrol for damage, clearing away debris and harmful proteins. But in the presence of the APOE4 protein-;the most important genetic risk factor for Alzheimer's disease-;the same cells cause harmful inflammation and clumps of misfolded proteins, according to a new study by scientists at Gladstone Institutes.

Microbiotica Secures Approvals to Begin Clinical Studies in EU and UK for New Microbiome Medicines

Microbiotica, a biopharma company developing a pipeline of oral precision microbiome medicines called live biotherapeutic products (LBPs), is pleased to announce that it has received regulatory approvals to initiate clinical studies for its first two programmes in advanced melanoma (MELODY-1) and ulcerative colitis (COMPOSER-1) in selected EU countries and the UK. Both studies are due to start shortly, with initial data readouts expected by the end of 2025.

The Complex Link Between DNA Modification and ALS

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease which remains incurable. The disease is characterized by the selective degeneration of upper motor neurons in the motor cortex as well as the lower motor neurons in the brainstem and spinal cord. The cause of ALS remains unknown in 90 percent of cases, which are referred to as sporadic ALS because there is no family history for the disease. Cumulative evidence suggests that sporadic ALS may result from complex interactions between genetic susceptibility and aging.

New Imaging Technique Offers Clearer View of Brain Function

Researchers have developed a new two-photon fluorescence microscope that captures high-speed images of neural activity at cellular resolution. By imaging much faster and with less harm to brain tissue than traditional two-photon microscopy, the new approach could provide a clearer view of how neurons communicate in real time, leading to new insights into brain function and neurological diseases.
