Detailed understanding of ‘one of the most complex organs’ could provide new ways to treat lung disorders

Details of lung cell molecular pathways that promote or inhibit tissue regeneration were reported by researchers from the Perelmen School of Medicine at the University of Pennsylvania in Cell this week. Their aim is to find new ways to treat lung disorders.

Study provides first structural glimpse of circadian clock's molecular machinery

Scientists have long known that circadian clocks- biochemical oscillators that control physiology, metabolism and behavior on a roughly 24-hour cycle- are present in all forms of life, including animals, plants, fungi and some types of bacteria. However, the molecular mechanisms that "run" these systems remain largely unknown.

Researchers find correlation between shorter telomeres and presence of heart failure

Each cell in the average human body contains 23 pairs of chromosomes, with four telomeres on each pair. Telomeres cover the end of the chromosome, protecting it from deterioration or fusion with adjacent chromosomes, much like the plastic tip at the end of a shoelace protects it from unraveling.

Art courses improve observational recognition skills among medical students

Observation skills are an essential component of any medical education, aiding doctors during patient exams and in making medical diagnoses, yet several studies have indicated inadequacies in this area among medical trainees and practicing physicians.

Reduced dose of chemotherapy has no effect on overall survival of liver cancer patients

Patients with the most common type of liver cancer who are taking the chemotherapy drug sorafenib can begin their treatment with a lower dose than is currently considered standard, and it will not affect how long they live when compared to patients who start on the full dose.

Yoganatomy helps medical students to connect, recharge and remember

Take a deep breath in. As you breathe out, answer: what did your internal intercostal muscles do when you took that breath? This isn't a common question in most yoga classes, but it is part of Yoganatomy at the Perelman School of Medicine, a yoga class that combines traditional yoga practice with reinforcement of lessons in gross anatomy.

Fluorescent dye imaging tool lights up benign brain tumors during surgery

An experimental imaging tool that uses a targeted fluorescent dye successfully lit up the benign brain tumors of patients during removal surgery, allowing surgeons to identify tumor tissue, a new study from researchers at the Perelman School of Medicine at the University of Pennsylvania shows.

How below-the-radar mergers fuel health care monopolies

Hospitals have gone on a doctor-buying spree in recent years, in many areas acquiring so many independent practices they've created near-monopolies on physicians.

Higher intake of red meat, poultry linked to greater diabetes risk

While a plant-based diet is generally considered healthier than a meat-based diet in preventing the risk of diabetes, not all meats affect the risk equally.

Study reveals benefits of defibrillators in heart disease patients treated with CRT

Some heart disease patients who are treated with cardiac resynchronization therapy (CRT) would live longer and have fewer hospital admissions if they also received a defibrillator, concludes a team of researchers led by Aston Medical School at Aston University.

Antibiotics may kill bacteria differently in vitro vs in vivo

Understanding exactly how antibiotics work (or don’t work) is crucial for developing alternative treatment strategies, not only to target new “superbugs,” but also to make existing drugs more effective against their targets.

Researchers identify gene variants linked to both type 2 diabetes and CHD risk

Type 2 diabetes (T2D) has become a global epidemic affecting more than 380 million people worldwide; yet there are knowledge gaps in understanding the etiology of type-2 diabetes.

Unfolded protein response could be cause of metabolic disorders, say researchers

The cell's response to unfolded or misfolded proteins could be a cause, rather than a consequence, of metabolic disorders, report researchers at the Medical University of South Carolina in an article published online ahead of print on September 4, 2017 by Nature Structural & Molecular Biology.
