Mediterranean Diet Increases Psychological Well-Being

Being depressed can negatively affect your appetite and our latest study, a systematic review of the best available evidence, found a clear link between the quality of a person's diet and their risk of depression. And it goes beyond the effect of diet on body size or other aspects of health that can affect mental health.

Chaperones Prepare Proteins For Folding By Their Own

A protein's folding patterns help them perform their dedicated tasks. As the real "doers" of the cell, even a tiny alteration in a protein's amino acid backbone can cause misfolding and hinder the protein's functionality or cause disease.

For instance, if tau, a protein that helps stabilize the structure of brain cells, is misfolded, it can form tau-tangles, which are commonly seen in Alzheimer's patients. Scientists seek to better understand protein folding to cure misfolding diseases, but this incredibly complex process requires sophisticated algorithms to identify the folding mechanisms.

They have proposed a new way to identify the most crucial factors for protein folding. They demonstrated the short simulation time of their approach on a small but intriguing protein, GB1 beta-hairpin. The study was published in the Journal of Chemical Physics.

New Federal Guidelines Seek To Limit CT Scans On Kids

Similar protocols have already been adopted by some New Jersey hospitals and healthcare providers to help keep children from possible harm. For the first time, federal officials have issued clinical guidelines for healthcare providers trying to determine if a child has a concussion, recommending that CT scans not be used routinely to diagnose these conditions.

Cholera Outbreaks: Fear and Anger Strikes Again in Zimbabwe

Sixty-year-old Emma Zhakata winces, struggling to hold back tears as she relates how her husband, one of 32 cholera victims in Zimbabwe, died within hours of falling ill. She never suspected her 69-year-old husband, Wonder Zhakata, would die suddenly after complaining that he felt weak and was suffering stomach pain. 

Dermatology Ways To Deal With The Most Common Acne Scars

For those who suffer from acne, current pimples aren’t always the problem, often it’s the scarring that’s left behind that can leave many of us feeling less than confident rocking a bare face. Acne scarring occurs because infected material from follicles within the skin spills out causing inflammation and damage to the dermis of the skin.

When the dermis is injured, the response is fibrosis, which is a complex process involving the deposition of collagen and other proteins. The combination of damage or thinning to the dermal layer of the skin and fibrosis causes acne scarring.

Pluripotent Stem Cells To Grow Human Esophageal Organoids

Scientists have been able to grow human esophageal tissue entirely from pluripotent stem cells (PSCs), which can form any tissue type in the body. Scientists working to bioengineer the entire human gastrointestinal system in a laboratory now report using pluripotent stem cells to grow human esophageal organoids. The study was published in the journal Cell Stem Cell.
