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.

Alpha-catenin protein provokes healthy cell bonding

In human relationships, a certain "spark" often governs whether we prefer one person more than another, and critical first impressions can occur within seconds. A team lead by Johns Hopkins researchers has found that cell-to-cell "friendships" operate in much the same way and that dysfunctional bonding is linked to the spread of cancer.

Scientists discover how ovarian tumors evade immune system

Scientists at Johns Hopkins have determined how the characteristic shedding of fatty substances, or lipids, by ovarian tumors allows the cancer to evade the body's immune system, leaving the disease to spread unchecked.

Prostate cancer tumors promote nerve growth

Prostate cancer - and perhaps other cancers - promotes the growth of new nerves and the branching axons that carry their messages, a finding associated with more aggressive tumors, said researchers from Baylor College of Medicine in the first report of the phenomenon that appears today in the journal Clinical Cancer Research.

Eating eggs when pregnant may help prevent breast cancer in offspring

A stunning discovery based on epigenetics (the inheritance of propensities acquired in the womb) reveals that consuming choline - a nutrient found in eggs and other foods - during pregnancy may significantly affect breast cancer outcomes for a mother's offspring.

Researchers discover genomic causes of acute lymphoblastic leukemia relapse

Scientists at St. Jude Children's Research Hospital have identified distinctive genetic changes in the cancer cells of children with acute lymphoblastic leukemia (ALL) that cause relapse.

Researchers identify a potentially universal mechanism of aging

Like our current financial crisis, the aging process might also be a product excessive deregulation.

Mouse model of prion disease mimics diverse symptoms of human disorder

A comprehensive mouse model of inherited prion disease exhibits cognitive, motor, and neurophysiological deficits that bear a striking resemblance to the symptoms experienced by patients with the human version of "mad cow disease," Creutzfeldt-Jakob disease (CJD).

Understanding donor-recipient genetics could decrease early kidney transplant complications

Researchers at the University of Pennsylvania School of Medicine have found an association between the genetics of donor-recipient matches in kidney transplants and complications during the first week after transplantation.

Mammogram most effective 12 months after radiation

Breast cancer patients who receive breast-conserving therapy and radiation do not need a follow-up mammogram until 12 months after radiation, despite current guidelines that recommend follow-up mammograms at between six and 12 months after radiation, according to a November 15 study in the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for Therapeutic Radiology and Oncology.

Discovery of novel approach to suppress prostate cancer progression

Researchers at the University of Southern California (USC) have found that inactivating a specific biomarker for aggressive prostate cancer blocks the development of prostate cancer in animal models.

Discovery of new species of bacterium that causes leprosy

A new species of bacterium that causes leprosy has been identified through intensive genetic analysis of a pair of lethal infections, a research team reports in the December issue of the American Journal of Clinical Pathology.

Lactic acid found to be important energy source for tumor cells

Many tumors have cells that burn fuel for activities in different ways. Tumor cells near blood vessels have adequate oxygen sources and can either burn glucose like normal cells, or lactic acid (lactate). Tumor cells further from vessels are hypoxic and inefficiently burn a lot of glucose to keep going. In turn, they produce lactate as a waste product.
