Scientists discover how excess oxygen changes a handful of proteins in the cells

When it comes to oxygen, you can have too much of a good thing. Breathing air that contains higher levels of oxygen than the usual 21 percent found in Earth's atmosphere can cause organ damage, seizures, and even death in people and animals, particularly if it's in excess of the body's oxygen needs.

Detection and targeting of splicing deregulation reveal a potential strategy for pAML therapy

Pediatric acute myeloid leukemia or pAML is a childhood blood cancer, one that has proved confounding to clinicians and researchers, with a high relapse rate and relatively few identified genetic mutations (compared to the adult version) that might explain its cause.

Research helps explain the metabolic differences of people living at high altitudes

Compared to those of us who live at sea level, the 2 million people worldwide who live above 4,500 meters (or 14,764 feet) of elevation - about the height of Mount Rainier, Mount Whitney, and many Colorado and Alaska peaks - have lower rates of metabolic diseases such as diabetes, coronary artery disease, hypercholesterolemia, and obesity.

Symptomatic COVID-19 is associated with deficits in task-related cognitive function and psychiatric symptoms

Researchers conducted a prospective population survey, functional brain imaging, and a cognitive task performance test to determine whether a history of symptomatic coronavirus disease 2019 (COVID-19) was associated with psychiatric and neurocognitive symptoms.

Interferon autoantibodies not implicated in long-COVID

Researchers assess the proportion of interferon autoantibodies in long COVID patients.

Evaluating how bacterial therapeutics may synergize with existing anti-cancer therapies

It may come as a surprise, but bacteria love to grow inside tumors. It's the environment - tumors are typically acidic, have low amounts of oxygen, and are filled with dead cells, which all facilitate bacterial growth.

Wrist-worn device can accurately predict troponin-I and obstructed arteries in five minutes

An experimental wrist-worn device was found to predict troponin-I and obstructed arteries with 90% accuracy in five minutes, according to research being presented at the American College of Cardiology's Annual Scientific Session Together With the World Congress of Cardiology.

Fixed-dose combination therapy provides better results than monotherapy for pulmonary hypertension

Patients with pulmonary arterial hypertension (high blood pressure in the arteries that supply the lungs, also called PAH) had approximately double the reduction in pulmonary vascular resistance (PVR) if they took the PAH medications macitentan (10 mg) and tadalafil (40 mg) together in a single tablet rather than either drug alone, according to research being presented at the American College of Cardiology's Annual Scientific Session Together With the World Congress of Cardiology.

Virtual or in person: Which kind of doctor’s visit is better, and when it matters

When the covid-19 pandemic swept the country in early 2020 and emptied doctors' offices nationwide, telemedicine was suddenly thrust into the spotlight. Patients and their physicians turned to virtual visits by video or phone rather than risk meeting face-to-face.

Role of phosphatidylinositol 3 kinase pathway in corneal damage due to blue light exposure

Researchers observe corneal damage by blue light exposure is due to PI3K/AKT pathway inhibition.

Landmark discovery provides a new perspective on tissue oxygenation

Cardiovascular medicine, hematology and pulmonary medicine may soon have the first-ever therapies to correct poor tissue oxygenation, a key driver of disease in millions, including peripheral artery disease, sickle cell disease, heart failure, stroke, emphysema and many others.

New imaging method could help make better decisions on personalized cancer treatment

Decisions on cancer treatment could become better tailored to individual patients with the adoption of a new imaging method being developed by University of Michigan researchers that maps the chemical makeup of a patient’s tumor.

New numerical model reveals degeneration mechanisms in mechanically loaded and inflamed cartilage

Understanding how the knee joint environment affects cartilage cells is crucial for joint health. Knowledge of cell-driven cartilage degeneration mechanisms can support the development of effective pharmaceutical interventions for osteoarthritis.

25% of COVID-19 patients have lasting reduction in lung function

In a recent study posted to the Preprints with The Lancet SSRN* server, researchers evaluated the impairment of pulmonary function in individuals suffering from post-acute sequelae of coronavirus disease 2019 (COVID-19) (PASC) or long coronavirus disease (long COVID) symptoms after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections.

Cedars-Sinai addresses life-threatening aorta condition

Her husband and their five children call Rosa Wernher "the Energizer bunny" because she is always on the go. For decades, not even her genetically inherited Marfan syndrome could keep her off her feet to prevent her from oil painting or from gliding down a ski slope--until it did.

Novel microfluidic model mimics a rare genetic disorder

Our bodies are made up of 60,000 miles of complex pipes that play a vital role in transporting nutrients throughout our bodies, performing waste disposal, and supplying our organs with fresh oxygen and blood.
