New Staining Method for Electron Microscope Specimens Safer and Cost-Effective

Researchers have developed a new staining method for electron microscope specimens based on double staining with hematoxylin, which is widely used as a staining agent for light microscopy, and lead solution. More...

Allogeneic Stem Cell Transplants Improve Microbiome, Immune Cells

Past studies have suggested ties between microbial diversity and favorable allogeneic hematopoietic stem cell transplantation (allo-HCT) outcomes, or transplants involving stem cells from healthy donors. The interactions between the gut microbial community and the immune system can influence an individual's response to a bone marrow transplant to treat leukemia, lymphoma, multiple myeloma, and other blood conditions.

Herpesvirus Infection May Increase the Risk of Developing Diabetes

Type 2 diabetes (T2D) is one of the most widespread metabolic diseases, with a 2019 worldwide prevalence estimate of 9.3%, exerting a high mortality burden mainly due to cardiovascular disease. More...

Five Methods Evaluated for Constrictive Tuberculous Pericarditis Diagnosis

Constrictive pericarditis is a rare and serious disease that accounts for approximately 0.5%–2% of all heart diseases. It results in decreased pericardial compliance and can severely affect the diastolic filling function of the heart, mainly as a symptom of right heart failure, such as multiple plasma chamber effusions and edema.

Combining RDTs Determines Dengue Immune Status

Dengue is an emerging arboviral infectious disease (DENV), transmitted through the bite of an Aedes mosquito that burdens much of the urbanized tropical and subtropical world. Current dengue diagnostics are primarily concerned with capturing active infections, thus no such method exists for determining primary or post-primary DENV infections, at the point of care. More...

Rapid Result Test for Complicated Urinary Tract Infections Proves Superior to Standard Urine Culture

Complicated urinary tract infections (cUTIs) are a significant burden on individual health and healthcare resources that must be diagnosed and treated early and accurately to reduce the risk of poor outcomes. Now, an advanced rapid result test better addresses polymicrobial infections in difficult cases, where bacterial interactions can impact antibiotic resistance. More...

Platelet Indices Are Associated with Syphilis Activities

Syphilis is caused by Treponema pallidum, which is a chronic sexually transmitted disease that has highly variable clinical courses and manifestations from a painless chancre to severe damage in the brain, heart, and other organs. More...
