Hepatitis B: 'Virus-cracking' Molecules Advance Cure

Researchers have found that certain molecules — currently under clinical trial — are able to 'crack' the protective shell of the hepatitis B virus, suggesting it may be possible to attack the virus after its already taken hold in the body. There is currently no cure for the virus, which can cause liver failure and cancer.

Combining DTF and RSBI Predicts success of Weaning from Mechanical ventilator

Weaning failure is a crucial hindrance in critically ill patients. Rapid shallow breathing index (RSBI), a well-known weaning index, has some limitations in predicting weaning outcomes. A new weaning index using point-of-care ultrasound with diaphragmic thickening fraction (DTF) has potential benefits for improving weaning success. The study researchers aim to evaluate the efficacy of a combination of DTF and RSBI for predicting successful weaning compared to RSBI alone.

A New Way to Kill Salmonella enterica, Study Finds

According to a team of researchers, the most economical way to kill bacteria that causes common food-borne illnesses, mostly caused by Salmonella enterica,  is heat, but, the mechanisms that kill Salmonella at lower temperatures were not fully understood until now.

Novel Possible Target for Blood Cancer Therapies

Researchers discovered the contribution of a specific gene in the proper development of blood cells that give rise to hematopoietic stem cells. The scientists also found that disruption of this gene resulted in various blood cancers and anemia in animal models. The findings identify a potential target for the development of treatments for some types of leukemia, anemia and other blood disorders.

Hyperlenses Makes a Clear View Of Living Cells; Study Says

According to a study, researchers observed that a quality of an optical material used to make hyperlenses makes it possible to see features on the surface of living cells in greater detail than ever before. An optical lens so powerful that it lets you view features the size of a small virus on the surface of a living cell in its natural environment. The study is published in Nature Materials.

By Using Quantum Chemical Methods, Solves Mystery of Biochemistry

A team of researchers solved one of the oldest puzzles of biochemistry by Using quantum chemical methods. They uncovered why there are 20 amino acids that form the basis of all life today, even though the first 13 amino acids generated over time would have been sufficient to form a comprehensive repertoire of the required functional proteins. The study has published in the journal PNAS.

Prevalence in Severe Psychological Trauma in 0.5% of the Population

Post-traumatic stress disorder (PTSD) can sometimes occur in a particularly severe form, known as complex post-traumatic stress disorder. In both forms of PTSD, patients suffer from an over-activation of the memories of traumatic events — in the form of images, smells, and sounds. In complex PTSD, patients also undergo personality changes and have difficulties with interpersonal relationships, in particular suffering from deep-seated mistrust, incapacity for intimacy, and greatly impaired self-worth.
