<p>With NIH support, scientists across the country and the world conduct wide-ranging research to improve the health of the nation. Groundbreaking NIH-funded research often receives top scientific honors. In 2013, all 3 recipients of the Nobel Prize in Physiology or Medicine, and all 3 awardees of the Nobel Prize in Chemistry, received NIH funding at different times in their careers. Four NIH-funded scientists also won awards from the Lasker Foundation in 2013. Here's just a small sampling of the research accomplishments made by NIH-supported scientists in 2013.</p>

A study by NIH researchers provided insight into the damage caused by mild traumatic brain injury and suggested approaches for reducing its harmful effects. <a href="http://www.ncbi.nlm.nih.gov/pubmed/24317693" title="Pubmed Abstract: Transcranial amelioration of inflammation and cell death after brain injury.">Pubmed Abstract »</a></p>

<p class="teaser-description">In an NIH-funded study, scientists were able to direct human stem cells to form networks of tiny blood vessels that can connect to the existing circulation in mice.

<p class="teaser-description">Pathologists currently classify endometrial tumors by examining tissue under a microscope. A comprehensive genomic analysis of nearly 400 endometrial tumors revealed 4 novel endometrial tumor subtypes and also found similarities to other cancers. The findings, by an NIH-funded research network, suggest that genomic classification of endometrial tumors could help guide treatment strategies. <a href="http://www.ncbi.nlm.nih.gov/pubmed/23636398" title="Pubmed Abstract: Integrated genomic characterization of endometrial carcinoma.">Pubmed Abstract »</a></p>

<p class="teaser-description">Autism, attention deficit hyperactivity disorder (ADHD), bipolar disorder, major depression, and schizophrenia were traditionally thought of as distinct mental disorders. However, their symptoms can overlap, making it difficult to distinguish between them. An international research consortium funded by NIH discovered that these disorders share certain genetic glitches. The finding may point to better ways to diagnose and treat these conditions. <a href="http://www.ncbi.nlm.nih.gov/pubmed/23453885" title="Pubmed Abstract: Identification of risk loci with shared effects on five major psychiatric disorders: a genome-wide analysis.">Pubmed Abstract »</a></p>

<p class="teaser-description">HIV, which causes AIDS in people, and the similar monkey virus SIV are thought to cause permanent infections in the body. Current therapies can control but not eliminate the virus. In an NIH-funded study, an experimental vaccine triggered a lasting immune attack in monkeys that eliminated all traces of SIV infection after a year or more. The finding points to a new strategy in the search for an effective AIDS vaccine. <a href="http://www.ncbi.nlm.nih.gov/pubmed/24025770" title="Pubmed Abstract: Immune clearance of highly pathogenic SIV infection.">Pubmed Abstract »</a></p>

<h4 class="teaser-title">The Human Microbiome</h4>
<p class="teaser-description">The human body hosts trillions of microbes. Were now gaining a better understanding of the many roles that microbial communities and their genes—collectively known as the microbiome—play in human health and disease.<strong> </strong>NIH-funded scientists surveyed all the <a href="/news-events/nih-research-matters/fungal-findings">fungi living on human skin</a>. They uncovered links between gut microbes and <a href="/news-events/nih-research-matters/gut-microbes-linked-rheumatoid-arthritis">rheumatoid arthritis</a>; discovered interactions among diet, gut microbes, and both <a href="/news-events/nih-research-matters/red-meat-heart-disease-link-involves-gut-microbes">heart disease</a> and <a href="/news-events/nih-research-matters/gut-microbes-diet-interact-affect-obesity">obesity</a>; and found that microbes may also influence the effectiveness of <a href="/news-events/nih-research-matters/gut-microbes-may-affect-cancer-treatment">cancer therapy</a> and <a href="/news-events/nih-research-matters/gut-microbes-affect-weight-after-gastric-bypass">gastric bypass surgery</a>.<br />

<p class="teaser-description">Decades of widespread antibiotic use have encouraged the spread of bacteria with resistance to multiple antibiotics. To combat these multidrug-resistant bacteria, researchers have been searching for new classes of antibiotics that work by different mechanisms than current drugs. NIH-funded scientists developed an innovative method to quickly identify antibiotics that can treat multidrug-resistant bacteria—and reveal how these bacteria-killing medications work. <a href="http://www.ncbi.nlm.nih.gov/pubmed/24046367" title="Pubmed Abstract: Bacterial cytological profiling rapidly identifies the cellular pathways targeted by antibacterial molecules.">Pubmed Abstract »</a></p>

<p class="teaser-description">Shock is a life-threatening condition in which blood pressure drops and not enough blood and oxygen can get to organs. Inflammation has been strongly linked with shock, and past research suggests that this inflammation involves the digestive system. An NIH-funded study of rats found that blocking digestive enzymes in intestines increases survival, reduces organ damage, and improves recovery after shock. The approach may lead to new therapies to improve patient outcomes. <a href="http://www.ncbi.nlm.nih.gov/pubmed/23345609" title="Pubmed Abstract: Pancreatic digestive enzyme blockade in the intestine increases survival after experimental shock.">Pubmed Abstract »</a></p>
