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.

Mouse study shows potential new way to unlock the power of immunotherapy for cancer patients

Immunotherapy has revolutionized cancer treatment by stimulating the patient's own immune system to attack cancer cells, yielding remarkably quick and complete remission in some cases. But such drugs work for less than a quarter of patients because tumors are notoriously adept at evading immune assault.

Stanford study reveals immunological deviations and lapses in severe COVID-19 cases

Some people get really sick from COVID-19, and others don't. Nobody knows why.

Protein uses two different mechanisms to inhibit viral infections

To protect humans against infection, a protein called MARCH8 tags the vesicular stomatitis virus (VSV) for destruction while it merely holds HIV hostage, a new study in eLife shows.

Only half of pregnant women worldwide get treatment for preventable Rh disease

Only half of pregnant women worldwide who need a treatment developed over 50 years ago to prevent Rh disease--an often-fatal condition in fetuses and newborns that is now exceedingly rare in the United States and Western Europe--actually receive it, finds a study led by researchers at Vagelos College of Physicians and Surgeons at Columbia University Irving Medical Center.

Real-life discussions may help counter anti-vaccination influences from social media

The flu vaccine is considered one of the great achievements in public health, and each year it prevents millions of people from getting sick and thousands of deaths.

Abnormal liver tests associated with poorer COVID-19 outcomes

Researchers at the Yale Liver Center found that patients with COVID-19 presented with abnormal liver tests at much higher rates than suggested by earlier studies.

New type of immunotherapy shows promise for advanced skin cancer

A new type of immunotherapy for the skin cancer malignant melanoma shows promising results. Three severely ill patients are now long-term survivors.

High concentrations of toxic pollutants were detected in stranded whales, dolphins

A study led by researchers at Florida Atlantic University's Harbor Branch Oceanographic Institute examined toxins in tissue concentrations and pathology data from 83 stranded dolphins and whales along the southeastern coast of the United States from 2012 to 2018.

A new method to diagnose brain tumors without any incisions

Brain tumors are typically diagnosed using MRI imaging, as taking a sample for a tissue biopsy is risky and may not be possible due to tumor location or a patient's poor health conditions.

New 3D CT scanning method shows how organs react during simulated heart massage

Rapid first aid during cardiac arrest makes the difference between life and death. But what happens to the heart and the internal organs when people come running and begin to give well-meaning but heavy-handed heart massage as they attempt to keep the person who has suffered a cardiac arrest alive?

Specific gene impairment may also protect people with Down syndrome

Scientists from Stanley Manne Children's Research Institute at Ann & Robert H. Lurie Children's Hospital of Chicago discovered that a set of genes with decreased expression in individuals with Down syndrome may lead to clinical abnormalities in this population, such as poor muscle development and heart valve problems.

Scientists explore mechanisms involved in the development of liver disease

Metabolic fatty liver disease, known as non-alcoholic fatty liver disease, is one of the most common causes of liver disease in Western countries and covers a spectrum of disorders.

3D organoid model helps better understand how tumor grows in natural microenvironment

Scientists at the Wake Forest Institute for Regenerative Medicine (WFIRM) have biofabricated human colorectal cancer miniature organs, called organoids, to better understand how a tumor grows in its natural microenvironment and its response to therapies.

Eosinophils contribute to antiviral host defense mechanisms during influenza

Eosinophils residing in the airways of mice respond to influenza A virus infection through alterations in surface expression of various markers necessary for migration and cellular immunity responses, according to research published in the Journal of Leukocyte Biology by researchers from Le Bonheur Children's Hospital and the University of Tennessee Health Science Center.

NIH-Moderna investigational vaccine protects mice from infection with SARS-CoV-2

The investigational vaccine known as mRNA-1273 protected mice from infection with SARS-CoV-2, the virus that causes COVID-19, according to research published today in Nature.

Bisphosphonates may be safe and beneficial for osteoarthritis patients

Bisphosphonates (a class of drugs that prevent the loss of bone density and used to treat osteoporosis and similar diseases) appear to be safe and beneficial for osteoarthritis patients.

Researchers evaluate the properties of anterograde and retrograde viral tracers

Researchers from the newly-established Center for Neural Circuit Mapping at the University of California, Irvine School of Medicine evaluate the properties of anterograde and retrograde viral tracers, comparing their strengths and limitations for use in neural circuit mapping. Results were published today as a primer in Neuron.

Novel technology tests the presence of thin membrane protrusions on breast cancer cells

Researchers at the University of Maryland School of Medicine (UMSOM) have developed a novel technology to test for the presence of thin membrane protrusions called "microtentacles" on breast cancer cells, which can help predict whether a tumor is likely to spread.

New computational model can help determine drug viability

About 50% of people who take the drug infliximab for inflammatory bowel diseases, such as Crohn's disease, end up becoming resistant or unresponsive to it.

Zombie cicadas infected with mind-controlling fungus

Mind-controlling fungus that infects the brains of cicadas can make them kill each other. These mutant critters, dubbed as zombie cicadas, are forced to infect other insects.
