Long-term use of liraglutide, a substance that helps to lower blood sugar levels in patients with type 2 diabetes, can have a deteriorating effect on insulin-producing beta cells, leading to an increase in blood sugar levels. This according to a study on mice implanted with human insulin-producing cells conducted by a team of scientists from Karolinska Institutet, Sweden, and the University of Miami, USA.

North American researchers have identified drugs that showed promising perspectives in treating cancers, according to a recent study published in Cancer Research. These drugs are normally used to treat other diseases, such as heart failure, cardiac arrhythmia, and infections.

A study published on February 4th in PLOS Pathogens reports that a new antiviral drug protects mice against a range of influenza virus strains. The compound seems to act superior to Oseltamivir (Tamiflu) and independent of the host immune response.

Use of common opioid painkillers such as codeine, morphine and oxycodone has more than quadrupled in Australia over the past decade and doubled worldwide over the same period a report published today in The Lancet by the International Narcotics Control Board (INCB) reveals.

Harvard Stem Cell Institute (HSCI) researchers have identified a faulty signaling pathway that, when corrected, in mice ameliorates the symptoms of Rett syndrome, a devastating neurological condition. The findings could lead to the discovery of compounds or drugs that may benefit children affected by the disease,

A University of California, San Diego School of Medicine study finds that weight loss programs that provide healthy fats, such as olive oil in the Mediterranean diet, or a low-fat, high-carbohydrate diet have similar impacts on pound-shedding. More specifically, the researchers report that a meal plan rich in walnuts, which are high in polyunsaturated fats, has a significant impact on lipid levels for women, especially those who are insulin-resistant.

Researchers at Tulane University and Southeast Louisiana Veterans Health Care System have developed a painkiller that is as strong as morphine but isn't likely to be addictive and with fewer side effects, according to a new study in the journal Neuropharmacology.
