Tracy C. Grikscheit, MD, pediatric surgeon and principal investigator at The Saban Research Institute of Children's Hospital Los Angeles, treats a large number of young patients who require surgery for various intestinal diseases. Since the intestinal microbiome is an important regulator of gut health and immune function, Grikscheit and her team investigated how surgical treatment of certain pediatric intestinal diseases have a long-term impact on intestinal flora.

DARIEN, IL - A new study found that alcohol-sleep relationship differed importantly by race and sex.
Exercise, particularly high-impact activity, builds stronger bones in children, even for those who carry genetic variants that predispose them to bone weakness, according to new research. The scientists say their findings underscore that genetics does not necessarily equate to destiny, and reinforce the importance of physical activity as a key factor to improve the bone health of children in the present and into later life.
COLLEGE STATION - Major rainfall across most of Texas triggering hordes of mosquitos coupled with seemingly constant mosquito-related Zika virus media reports from around the globe may have set the stage perfectly for what one researcher deems as a very significant discovery in man's war against earth's leading human disease carrier.
Researchers at The University of Texas Medical Branch at Galveston have found that cancer survivors who were diagnosed at adolescent and young adult ages are more likely to be current cigarette smokers than people who have not had cancer. The findings of this study are currently available in Cancer.
Smoking is the leading cause of cancer but the study found that cancer survivors were not staunch non-smokers.
Scientists used X-rays to discover what creates one butterfly effect: how the microscopic structures on the insect's wings reflect light to appear as brilliant colors to the eye.
The results, published today in Science Advances, could help researchers mimic the effect for reflective coatings, fiber optics or other applications.
A team led by researchers from UCSF and Yale has found that half of people newly infected with HIV experience neurologic issues. These neurologic findings are generally not severe and usually resolve after participants started anti-retroviral therapy.
San Diego, Calif. - An emerging cancer therapy has colorectal tumors surrounded. Presenters at the 2016 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI) are unveiling a novel radioimmunotherapy that combines a cancer-seeking antibody with potent radionuclide agents, resulting in complete remission of colorectal cancer in mouse models.
Theranostic drugs are powerful newcomers in oncology's arsenal. In addition to providing targeted treatment, in many cases they double as imaging agents that can monitor the effectiveness of therapy.
San Diego, Calif. - Malignant neuroendocrine tumors (NETs) are relatively rare, notoriously difficult to treat, and associated with poor long-term survival. According to research presented at the 2016 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI), an investigative blood test could predict how patients will respond to peptide receptor radionuclide therapy (PRRT) before they commit to a course of treatment.
TUCSON, Ariz. - Sixty-five is the age when many people retire, kick back and take it easy. And so it often is with the human immune system.
After years of fending off influenza and other infectious diseases, the immune system gradually starts to lose its oomph for fighting infection. As a result, viruses, bacteria and other microbial intruders are a common killer of adults 65 and older.
RICHLAND, Wash. - After their nanorods were accidentally created when an experiment didn't go as planned, the researchers gave the microscopic, unplanned spawns of science a closer look.
Chemist Satish Nune was inspecting the solid, carbon-rich nanorods with a vapor analysis instrument when he noticed the nanorods mysteriously lost weight as humidity increased. Thinking the instrument had malfunctioned, Nune and his colleagues moved on to another tool, a high-powered microscope.
When a molecule emits a blink of light, it doesn't expect it to ever come back. However researchers have now managed to place single molecules in such a tiny optical cavity that emitted photons, or particles of light, return to the molecule before they have properly left. The energy oscillates back and forth between light and molecule, resulting in a complete mixing of the two.
Columbus, Ohio - A new study suggests that blocking an enzyme called PRMT5 in tumor cells could be a promising new strategy for the treatment of glioblastoma (GB), the most aggressive and lethal form of brain cancer.
The study by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James) shows that knocking down PRMT5 (protein arginine methyltransferase 5) might force the cells into senescence and slow or stop tumor growth.
Pain-relieving prescription opioids are the subject of a new original investigation and research letter published online by JAMA Internal Medicine.
In the original investigation, Anupam B. Jena, M.D., Ph.D., of Harvard Medical School, Boston, and coauthors analyzed pharmacy claims from a 20 percent random sample of Medicare beneficiaries in 2011 to estimate the frequency of opioid prescribing at hospital discharge among those patients who did not have an opioid prescription 60 days prior to hospitalization.
Breastfeeding in children who had received no antibiotics before weaning was associated with a decreased number of antibiotic courses after weaning and a decreased body mass index (BMI) later in childhood, according to an article published online by JAMA Pediatrics.
