Becoming More Sensitive to Pain Increases the Risk of Knee Pain not Going Away

Becoming more sensitive to pain, or pain sensitization, is an important risk factor for developing persistent knee pain in osteoarthritis, according to a new study by researchers at Université de Montréal and its affiliated Maisonneuve Rosemont Hospital Research Centre (CRHMR), in collaboration with researchers at Boston University. Their findings were published Oct. 11 in the journal Arthritis & Rheumatology

New Insight Into Enzyme Evolution

The brilliant physicist Richard Feynman famously said that, in principle, biology can be explained by understanding the wiggling and jiggling of atoms. A new research explains how this 'wiggling and jiggling' of the atoms in enzymes the proteins that make biological reactions happen is 'choreographed' to make them work at a particular temperature.

Enzyme catalysis is essential to life, and this research is based on how enzymes have evolved and adapted, enabling organisms to evolve to live at different temperatures.

Single Plane Illumination Microscopy In Cell Biology

Visualizing cell behavior has been the goal of many techniques developed in the 20th and 21st century. Cells were initially visualized after removing from the organism after death. However, real-time visualization of cells through fluorescent labeling still proved difficult due to the degree of transparency required to see the fluorescence.

Similarly, imaging techniques have had problems with light scattering. Selective plane illumination microscopy (SPIM) or light-sheet microscopy differs offers high-resolution imaging at various cell depths in live tissues.

Potential Side Effects of General Anesthesia

The short-term effects of anesthesia are usually short-lived and manageable, but long-term neurological effects are a potential concern. Anesthetics , and in particular the inhaled ones used to put patients "under" for surgery, are considered one of the most important medical advances in history, the opening of the door for the entire modern field of surgery.

There are an estimated 46 million surgical procedures done each year in the US, and all anesthetics which make almost every one of these surgeries possible remain among the most toxic and poorly understood of all drugs.

Clinician Praised For Saving lives In Intensive care

Clinician praised for saving lives in intensive care through research. Thousands of patients in Intensive Care Units (ICUs) have benefited from the clinical trials led in New Zealand by Auckland City Hospital intensive care specialist and clinical researcher Dr. Colin McArthur.

For more than two decades, Dr. McArthur and his colleagues have questioned and tested treatment options available to critically-ill patients in the ICU, to reveal the safest, most effective ways to treat illnesses that pose a threat to life.
