Dietary medium chain triglycerides prevent development of nonalcoholic fatty liver disease
The incidence of nonalcoholic fatty liver disease (NAFLD) associated with obesity is increasing rapidly and is a major source of liver pathology. A new study from investigators at the U.S. Department of Agriculture Agricultural Research Service’s Arkansas Children’s Nutrition Center suggest dietary substitution of saturated fat in the form of medium chain triglycerides (MCT) for polyunsaturated fats can prevent progression of NAFLD-associated liver injury and that MCT containing oils could be a new NAFLD therapy.

Repairing articular cartilage defects with an injectable gel engineered with gene modified BMSCs
Tissue engineering combined with gene therapy technology has the potential to manage the repair of defective articular cartilage. In this study, through minimally invasive injection methods the authors were able to repair rabbit articular cartilage defects with CS/PVA gel and gene modified BMSCs.

Epoxide hydrolase inhibition and thiazolidinediones: A therapy for cardiometabolic syndrome
Scientists at the Medical College of Wisconsin and UC Davis, led by Dr. John Imig and Dr. Bruce Hammock have determined the synergistic actions of inhibiting soluble epoxide hydrolase (sEH) with tAUCB (trans-4-(4-[3-adamantan-1-yl-ureid]-cyclohexyloxy)-benzoic acid) and activating peroxisome proliferator-activator receptor (PPAR) with the thiazolidinedione rosiglitazone on the pathological progression of cardiometabolic syndrome. Cardiometabolic syndrome occurs with obesity and hypertension increasing the risks for cardiovascular disease and causing significant and rapidly progressive kidney disease.

Rapamycin reduces seizures in mennonite children with rare disorder
Rapamycin, a drug used to prevent organ rejection after transplants, may help to reduce seizures and improve cognitive skills in children with a rare neurodevelopmental disorder found in the Old Order Mennonite communities of Ohio, Pennsylvania and New York.

Study examines methods, procedures for improved diagnosis of ectopic pregnancy
For women with abdominal pain or vaginal bleeding during early pregnancy, patient history and clinical examination alone are insufficient to indicate or eliminate the possibility of ectopic pregnancy, while transvaginal sonography appears to be the single best diagnostic method for evaluating suspected ectopic pregnancy, according to an analysis of previous studies reported in the April 24 issue of JAMA.

Use of anti-epileptic drug during pregnancy associated with increased risk of autism
Maternal use of valproate (a drug used for the treatment of epilepsy and other neuropsychological disorders) during pregnancy was associated with a significantly increased risk of autism in offspring, according to a study in the April 24 issue of JAMA. The authors caution that these findings must be balanced against the treatment benefits for women who require valproate for epilepsy control.

Memory retrieval and outcome prediction
Memories often mislead when trying to predict outcomes, such as the winner of a sporting event or the likelihood of rain, according to a study. Faced with uncertainty, humans typically rely on recollections and retrieve memories of similar events, to serve as indicators of possible results.

Pre-Columbian Mexican temple precinct housed specialized priesthood
Excavations at Mexico’s Valley of Oaxaca have recovered the region’s earliest known temple precinct, which, according to a study, was staffed by a specialized priesthood. Elsa Redmond and Charles Spencer led excavations in Mexico that took place at a site known as El Palenque in Oaxaca. The archaeological data document a 300-100 B.C. walled enclosure that included three multi-room temples and two priests’ residences.

Tracking the transmission of emerging infectious diseases
A study reveals a strategy for predicting the risk of emerging infectious disease transmission from animals to humans. Most emerging infectious diseases affecting humans originate in animals, but the animal sources are not usually identified until after disease emergence.

Producing petroleum replicas in E. coli
Researchers have produced hydrocarbons in Escherichia coli that are replicas of the petroleum-based molecules used in retail transportation fuels. Current biofuels containing alcohol or biodiesel require elaborate processing and are not fully compatible with most modern engines; as a result, they meet only a small fraction of the transportation fuel demand.

Bacterial attack against metastatic pancreatic cancer
Researchers report that a weakened, radioactive strain of Listeria monocytogenes can reduce the number of metastatic tumors in mice with pancreatic cancer without harming healthy cells. Pancreatic cancer often spreads to distant organs before the original tumor grows large enough to be detected. There are no effective treatments once the disease spreads, and the 5-year survival rate has remained at 4% for the past 25 years.

Scientists identified the source for the H7N9 influenza viruses causing human infections
In March 31, 2013, human infections with a novel H7N9 influenza virus were announced by the National Health and Family Planning Commission, China. In 2013 issue of Chinese Science Bulletin, a paper identified that the avian H7N9 viruses simultaneously circulating in the live poultry markets are the direct source for the viruses causing human infections. It provides a basis for the government to take actions in order to control its threat to humans.

Pinpointing the start of consciousness in babies
Researchers have discovered a signal in the nervous system of infants that reliably identifies the beginning of visual consciousness -- the ability to see and remember things seen. Until now, demonstrating conscious perception of any kind in infants has been challenging because infants cannot report whether they have seen a briefly presented visual scene.

Ants go marching, in order by age
If you’re a middle-aged ant, you’re likely to roam your colony more than your younger and older counterparts, and also to have a weaker social network, a new study shows. To maintain their sophisticated colony structures, ants must perform a multitude of tasks. These include tending the young, nest cleaning and foraging.

Exoplanets with a chance of water, identified by Kepler

Stressful conditions help moms help their offspring
Pregnant females pressed by crowded living situations are unknowingly setting their offspring up for success, a new study shows. A mother’s influence can prepare her unborn child for some of the conditions that child may face, though, to date, little is known about the cues and the mechanisms involved in this process.

Exclusive breastfeeding curbs HIV in breast milk
HIV-infected women who want to breastfeed should do so exclusively (no feeding with other fluids or foods) for the first six months of a baby’s life, a new study of HIV-infected mothers in Zambia suggests. Women who chose long-term exclusive breastfeeding may have the lowest risk of transmitting the virus to their babies through breast milk, the findings show.

Auricular pressing relieves pre-exam anxiety
Pre-exam anxiety is a type of acute stress disorder. The disorder typically manifests as nervousness and increased heart rate, and can affect students’ exam results. Auricular pressing is one type of auricular point therapy, in which cowherb seed is fixed on the auricular point using tape, to perform compression stimulation.

Chronic visceral hypersensitivity is a pathophysiological characteristic of irritable bowel syndrome. Each level in the brain-gut axis, i.e. neurotransmitters in the periphery, spinal cord, and central nervous system, all participate in the occurrence of visceral hypersensitivity.
