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.
Huntington's disease is caused by a mutation in the Huntingtin gene (HTT), which appears in adults and features motor, cognitive and psychiatric alterations.
According to a new study, a gene associated with an exceptionally long-life span in human beings guards the brain stem cells against the adverse effects of stress.
In people with central nervous system (CNS) lymphoma, cancerous B cells--a type of white blood cell--accumulate to form tumors in the brain or spinal cord, often in close proximity to blood vessels.
A test that monitors blood levels of DNA fragments released by dying tumor cells may serve as an accurate early indicator of treatment success in people in late stages of one of the most aggressive forms of skin cancer, a new study finds.
The presence of high salt and nitrogen concentrations in high- tunnel soils may make it more challenging to rebuild a healthy soil microbiome following a soil-clearing event, according to microbial ecologists in Penn State's College of Agricultural Sciences.
Past exposure to seasonal coronaviruses (CoVs), which cause the common cold, does not result in the production of antibodies that protect against the novel coronavirus SARS-CoV-2, according to a study led by Scott Hensley, PhD, an associate professor of Microbiology at the Perelman School of Medicine at the University of Pennsylvania.
DNA sequences that can fold into shapes other than the classic double helix tend to have higher mutation rates than other regions in the human genome.
Researchers at the University of Massachusetts Amherst have gained new insight into the biological processes of a chytrid fungus responsible for a deadly skin infection devastating frog populations worldwide.
A new study of autism risk genes by UC San Francisco and UC Berkeley scientists implicates disruption in prenatal neurogenesis - a process in which specialized "progenitor" cells give rise to new brain cells - in the development of autism spectrum disorders (ASDs).
It was an unexpected discovery that started with an analysis of more than 1,000 genes. The question: why game-changing cancer immunotherapy treatments work for only a fraction of patients.
Breast cancer could be identified more precisely than existing methods using blood specimens and exclusive proteomics-based technology.
Huanglongbing (HLB), also called citrus greening disease, is detrimental to the citrus industry and causes unparalleled levels of destruction around the world. But despite this fact, there is no proven treatment for this.
Evolution within groups of tumor cells follows the principles of natural selection, as evolution in pathogenic microbes.
A new study out of the University of Chicago and Stanford University on pairs of twins with and without food allergies has identified potential microbial players in this condition. The results were published on Jan. 19 in the Journal of Clinical Investigation.
Researchers at University of California San Diego School of Medicine, in collaboration with Dutch scientists, have found that certain metabolites -- small molecules produced by the process of metabolism -- may be predictive indicators for persons at risk for recurrent major depressive disorder.
Scientists from the Lerner Research Institute at Cleveland Clinic have designed an innovative, patient-derived model of ulcerative colitis that will help scale up studies into new therapies for chronic inflammatory bowel disease.
Proteogenomic studies may provide a better understanding of how to match cancer patients with an effective treatment for their specific cancer.
Nutrients are the structural components of food that the body needs to function properly. They are divided into macronutrients (proteins, fats, carbohydrates) and micronutrients (vitamins, provitamins, various minerals, and so on). Their shortage is called nutritional deficiency.
A potential preventive treatment for Crohn's disease, a form of inflammatory bowel disease, has been demonstrated in a mouse model and using immune-reactive T cells from patients with Crohn's disease.
Researchers have found how a protein governs the behavior of proteins associated with the activity in mitochondria, which is impacted in Alzheimer's disease.
