In a study with chronic adolescent and adult meth users in South Korea, MRI brain scans showed decreased thickness in the gray matter of younger users’ frontal cortex. Adult brains showed less damage.
To mitigate the dangers inherent to insulin dosing, scientists have created a novel, long-lasting “smart” insulin that self-activates when blood sugar soars. Tests on mouse models for type 1 diabetes show that one injection works for a minimum of 14 hours, during which time it can repeatedly and automatically lower blood sugar levels after mice are given amounts of sugar comparable to what they would consume at mealtime.
The “smart” insulin, Ins-PBA-F, acts more quickly, and is better at lowering blood sugar, than long-acting insulin detimir, marketed as LEVIMIR. In fact, the speed and kinetics of touching down to safe blood glucose levels are identical in diabetic mouse models treated with Ins-PBA-F and in healthy mice whose blood sugar is regulated by their own insulin. The report will be published Feb. 9 in PNAS Early Edition.
A research collaboration between Intermountain Healthcare, the University of Utah’s Obstetrics and Gynecology Department, and the University of Utah’s Psychiatry Department found that induced or augmented labor does not result in an increased risk of children developing autism spectrum disorder (ASD).
Scientists at the University of Utah and the University of Georgia have uncovered a pharmacological target that could enable development of novel drugs against antibiotic-resistant pathogens, including Methicillin-resistant Staphylococcus aureus (MRSA), Vancomycin-resistant enterococci (VRE) and other infectious Gram-positive organisms such as Listeria and Mycobacterium tuberculosis. The target was revealed upon discovery of a Gram-positive bacteria-specific pathway for making heme, an essential iron-carrying molecule. The findings were reported in the journal, Proceedings of the National Academy of Sciences (PNAS).
Researchers at Huntsman Cancer Institute (HCI) at the University of Utah have found that defects in how cells are squeezed out of overcrowded tissue to die, a process called extrusion, may be a mechanism by which pancreatic cancer begins. From these findings, they may have identified an effective way to reverse the defective extrusion’s effects without destroying normal tissues nearby. The results were published in the latest edition of the journal eLife.
1.4 million Americans suffer from uncomfortable abdominal cramping and diarrhea that come with inflammatory bowel disease (IBD). The condition is associated with an imbalance among the thousands of species of “good” bacteria that inhabit the gut. A University of Utah study published on Jan. 22 in Cell Host and Microbe demonstrates that a component of the immune system, MyD88, coordinates a host immune response that promotes a healthy colony of good bacteria, and digestive health.
A discovery by researchers at Huntsman Cancer Institute shows that looking at whether a man’s uncles and great-grandparents, among other second- and third-degree relatives, had prostate cancer could be as important as looking at whether his father had prostate cancer. A more complete family history would give physicians a new tool to decide whether or not a PSA test was appropriate.
Results from a study published on Jan. 2 in Science defy textbook science, showing for the first time that the building blocks of a protein, called amino acids, can be assembled without blueprints – DNA and an intermediate template called messenger RNA (mRNA). A team of researchers has observed a case in which another protein specifies which amino acids are added.
In addition to incurring serious dental problems, memory loss and other physical and mental issues, methamphetamine users are three times more at risk for getting Parkinson’s disease than non-illicit drug users.
Examination of DNA from 21 primate species – from squirrel monkeys to humans – exposes an evolutionary war against infectious bacteria over iron that circulates in the host’s bloodstream. Supported by experimental evidence, these findings, published in Science on Dec. 12, demonstrate the vital importance of an increasingly appreciated defensive strategy called nutritional immunity.
It’s a virus that has long been characterized as dangerous and even deadly, but new research shows infant deaths from respiratory syncytial virus (RSV) are actually quite uncommon in the 21st century. Researchers at the University of Utah have shown there are approximately 42 deaths annually associated with RSV in the United States - much lower than had been reported previously - and of those deaths, the majority are in infants and young children that have complex preexisting chronic conditions.
A study by researchers at the University of Utah's Huntsman Cancer Institute has discovered the unusual role of lactate in the alveolar soft part sarcoma, while also confirming that a fusion gene is the cancer-causing agent in the disease
Black children are less likely to be diagnosed with and less likely to receive broad-spectrum antibiotics for ear infections than white children are, a new study has found. But the discrepancy in prescribing fewer broad-spectrum antibiotics means black children actually are more likely to receive care that aligns with the recommended guidelines for treating ear infections. Possible behaviors explaining the trend are overdiagnosis and overtreatment in white children and underdiagnosis and undertreatment in black children. The report appears in Pediatrics online on November 17, 2014.
Study shows that one way to solve problems of synthesis of natural compounds is to figure out how an organism solves the problem itself, and then modify it for a particular use.
A University of Utah-led study reports that cancers select against a protein complex called the mitochondrial pyruvate carrier (MPC), and re-introduction of MPC in colon cancer cells impairs several properties of cancer, including growth. The research, which appears online on Oct. 30 in Molecular Cell, implicates changes in a key step in metabolism – the way cellular fuel is utilized – as an important driver of colon cancer that is also likely to be important in many other cancer settings.
The award signifies a top-10 finish in UHC’s prestigious quality and safety rankings, a comparison of teaching hospitals based on quality measures, patient safety and satisfaction indictors, mortality rates and readmissions.

A new study shows that when given the choice between a less costly “open” operation or a pricier laparoscopy for their children’s appendicitis, parents were almost twice as likely to choose the less expensive procedure – when they were aware of the cost difference.
Several times a year, eye surgeons from the University of Utah's Moran Eye Center set up medical eye camps in some of the most neglected corners of the world, including South Sudan, Micronesia, Haiti, Bolivia and Myanmar. The medical teams, however, don’t just work for a week and leave the country —throughout the process medical teams work with local providers to perform as many surgeries as possible and to train local partners on how to provide basic eye care and perform simple surgeries, which allows countries to develop a permanent source of eye care for the underserved regions.
Researchers at Huntsman Cancer Institute (HCI) at the University of Utah have identified and characterized mutated forms of the gene that encodes BCR-ABL, the unregulated enzyme driving the blood cancer chronic myeloid leukemia (CML).
In an environment where others struggle to survive, Tibetans thrive in the thin air of the Tibetan Plateau, with an average elevation of 14,800 feet. A study led by University of Utah scientists is the first to find a genetic cause for the adaptation and demonstrate how it contributes to the Tibetans’ ability to live in low oxygen conditions. The work appears online in the journal Nature Genetics on Aug. 17, 2014.
Senator and ophthalmologist Rand Paul (R-Ky) will join a medical team from the University of Utah’s John A. Moran Eye Center at a weeklong surgical camp in Guatemala beginning Aug. 14.

The first investigator to join the new center is Danny Hung-Chieh Chou, Ph.D., who will develop novel forms of injectable insulin to make life better for patients with T1D.
The findings in the paper, titled “Protective buttressing of the hominin face,” present an alternative to the previous long-held hypothesis that the evolution of the robust faces of our early ancestors resulted largely from the need to chew hard-to-crush foods such as nuts.
Four new genes have been added to the growing list of those known to cause increased breast cancer risk when mutated through the efforts of researchers at Huntsman Cancer Institute (HCI) at the University of Utah, who lead an international consortium working to find more gene mutations that cause inherited breast cancer susceptibilities.
Scientists have developed a powerful tool called pVAAST that combines linkage analysis with case control association to identify disease-causing mutations in families faster and more precisely than ever before.
Researchers who investigated the level of kidney function and subsequent cancer risk in more than one million adults have found that reduced glomerular filtration rate (GFR) — a key measure of reduced kidney function and chronic kidney disease (CKD) — is an independent risk factor for renal and urothelial cancer but not other cancer types.
It was long assumed that the joining of egg and sperm launched a dramatic change in how and which genes were expressed. Instead, new research shows that totipotency is a step-wise process, manifesting as early as in precursors to sperm, called adult germline stem cells (AGSCs), which reside in the testes. The research was published online in the journal Cell Stem Cell.
Mice severely disabled by a condition similar to multiple sclerosis (MS) were able to walk less than two weeks following treatment with human neural stem cells.
