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.

First Chronic Wound Murine Model to Profile the Effects of Cellular Senescence

A new research paper was published on the cover of Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 15, Issue 8, entitled, "A chronic wound model to investigate skin cellular senescence."

Novel 3D Structure can Serve as Blueprint to Engineer New BoNT/E Variants

A team of researchers from the University of California, Irvine, have revealed the first crystal structures of the receptor-binding domain of botulinum neurotoxin E (BoNT/E) in complex with its human neuronal receptors, synaptic vesicle glycoprotein 2A (SV2A).

Abnormal Immune Activity in Astrocytes Causes Dementia-Related Cognitive Deficits

People with dementia have protein build-up in astrocytes that may trigger abnormal antiviral activity and memory loss, according to a preclinical study by a team of Weill Cornell Medicine investigators.

Spatial Organization of Chromosomes and the Role of DNA Tension

Two protein complexes are primarily responsible for chromosomal spatial organization in human cell nuclei. DNA tension has an unanticipated function in this. Together with Austrian colleagues, nanoscientist Cees Dekker and his PhD candidate Roman Barth of TU Delft’s Kavli Institute of Nanoscience published their detailed visualization in Nature on April 19th, 2023.

Using Cellular Reprogramming to Make the Heart Function Like New Again

A recent study using mice has revealed a way to turn back the clock after heart attack. The researchers behind the work used RNAs to instruct cells in an injured heart to eliminate scar tissue and recreate cardiac muscle, allowing the heart to function like new again.

Inhibition of p21 may be a Promising Strategy for Limiting Age-Related Inflammatory Disorders

A new research paper was published on the cover of Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 15, Issue 7, entitled, "p21 facilitates chronic lung inflammation via epithelial and endothelial cells."

MET+LEU Cocktail Prevents Cellular Senescence and Disrupted Proteostasis Induced by Myotube Atrophy

A new research paper was published on the cover of Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 15, Issue 6, entitled, "Cellular senescence and disrupted proteostasis induced by myotube atrophy are prevented with low-dose metformin and leucine cocktail."

Newly Identified Rare Genetic Variants Could Point to One of the General Mechanisms Driving AMD

A study from the National Eye Institute (NEI) identified rare genetic variants that could point to one of the general mechanisms driving age-related macular degeneration (AMD), a common cause of vision loss in older adults.

Previously unknown telomere and cancer connection to the immune system revealed

Johns Hopkins Medicine scientists say their 20-year study of more than 200 people with premature aging syndromes caused by abnormally short telomeres, or shortened repetitive DNA sequences at the ends of chromosomes, may upend long-held scientific dogma and settle conflicting studies about how and whether short telomeres contribute to cancer risk.

Rare genetic variants identified that point to MAC as a therapeutic target for age-related macular degeneration

A new study conducted at the National Eye Institute (NEI) has identified incredibly rare genetic variants that might uncover the mechanisms underlying the development of AMD.

Single monoclonal antibody infusion can strengthen the body's fight against yellow fever

New research from Oregon Health & Science University and collaborators indicates lab-made antibodies may be able to cure people infected with yellow fever, a virus for which there is no treatment.

Using AI to screen for genetic mutations in cancerous brain tumors in under 90 seconds

Using artificial intelligence, researchers have discovered how to screen for genetic mutations in cancerous brain tumors in under 90 seconds -; and possibly streamline the diagnosis and treatment of gliomas, a study suggests.

Study describes why COVID-19 subvariants accelerated the pandemic

The COVID-19 pandemic has killed nearly 7 million people worldwide (1.1 million in the United States) and severely harmed many millions more, though vaccines and antiviral treatments measurably reduced the potential loss of life and health.

Single mechanosensitive protein shown to contribute to fibrosis in multiple organs

Researchers from Kyushu University have found how a single mechanosensitive protein induces the process that thickens and scars tissue, known as fibrosis. The protein, called VGLL3, was shown to contribute to fibrosis in multiple organs.

Keeping lymph nodes in the body can boost the efficacy of cancer immunotherapy

Cancer treatment routinely involves taking out lymph nodes near the tumor in case they contain metastatic cancer cells.

Age-related sarcopenia prevented by AAV1.NT-3 gene therapy

A new research paper was published on the cover of Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 15, Issue 5, entitled, "AAV1.NT-3 gene therapy prevents age-related sarcopenia."

“Bacterial suicide squad” recruits and activates innate and adaptive antitumor immune responses

Combining discoveries in cancer immunology with sophisticated genetic engineering, Columbia University researchers have created a sort of "bacterial suicide squad" that targets tumors, attracting the host's own immune cells to the cancer to destroy it. The new work, published today in Science Advances, marks a major step forward in efforts to enlist non-pathogenic bacteria to combat cancer.

Study findings reveal drug development possibilities for brain diseases

Nearly two dozen experimental therapies targeting the immune system are in clinical trials for Alzheimer's disease, a reflection of the growing recognition that immune processes play a key role in driving the brain damage that leads to confusion, memory loss and other debilitating symptoms.

Innovative method to quickly identify bacteria in fluids

Shine a laser on a drop of blood, mucus, or wastewater, and the light reflecting back can be used to positively identify bacteria in the sample.

Scientists discover two ways to preserve diseased upper motor neurons in ALS

Northwestern Medicine scientists have discovered two ways to preserve diseased upper motor neurons that would normally be destroyed in ALS, based on a study in mice. Upper motor neurons initiate movement, and they degenerate in ALS.
