Association between depression severity and poor glycemic control among Hispanics with diabetes

Research found a strong association between depression severity and poor glycemic control among Hispanics with diabetes, particularly those with moderate-severe depression. This underlines the importance of identifying and treating depression to improve diabetic outcomes in this high-risk population.

Patients with metabolic syndrome, moderate coronary calcium have greater risk of blocked arteries

Researchers at Cedars-Sinai Medical Center found that patients with metabolic syndrome and moderate coronary calcium have a greater chance of having blockage in their arteries. The study analyzed 1,043 patients without known heart disease and found that those with metabolic syndrome had a significantly higher risk of ischemia during st...

Global analysis of membrane proteins

A team of researchers has created simple structural models for over 600 Escherichia coli membrane proteins using a combination of experimental techniques and theoretical methods. The study reveals which membrane proteins can be produced in large quantities by the bacterium, crucial information for drug development.

Rice unveils 'green' microcapsule production method

The new process, developed by Michael Wong and his team, involves mixing polymer, salt, and tiny silica particles to create hollow spheres that can encapsulate drugs, flavor compounds, and other molecular cargo. The microcapsules have potential applications in drug delivery, medical imaging, and enzyme protection.

Ontario's mental health care evaluated

A University of Toronto report assesses the overall performance of 11 psychiatric hospitals and 45 acute-care facilities in Ontario, highlighting strengths and weaknesses. The study identifies key areas for improvement, including patient participation, continuity of care, regional variation, and evidence-based care.

Hydrogen sensors are faster, more sensitive

Researchers at Argonne National Laboratory have developed a new type of hydrogen sensor that shows rapid and reversible responses to hydrogen gas. The sensors use a discontinuous palladium thin film on a glass slide coated with a self-assembled monolayer, resulting in faster response times and increased sensitivity.

Severe sleep apnea may be a risk factor for liver damage

A study published in Hepatology found that severe sleep apnea is a risk factor for liver damage, independent of body mass index. Patients with severe sleep apnea had higher levels of insulin resistance and fatty liver disease, suggesting a link between obstructive sleep apnea and the development of nonalcoholic steatohepatitis.

Study is first to show side-stream smoking is as damaging to IVF success as being a smoker

A study of 225 women undergoing IVF found that side-stream smoking was associated with lower implantation and pregnancy rates compared to non-smoking and mainstream smoking groups. The researchers are calling for women to reduce or prevent exposure to cigarette smoke, especially when trying to conceive.

Survey of academic medical centers' standards for clinical-trial agreements with industry

Medical schools have inconsistent standards for allowing industry sponsors to control research, including revising manuscripts, limiting investigator roles, and reviewing data. Some institutions prioritize public interest over sponsor interests, while others are more permissive, raising concerns about researchers' autonomy.

The Bcl-2 family tree

The Bcl-2 family of proteins regulates apoptosis and cell death in response to various cellular stressors. Members of this family include anti-apoptotic proteins such as Bcl-2 and Bcl-xL, which inhibit caspase activation and promote cell survival.
