Research reveals role of fat storage cells in anti-obesity intervention

New research from a team at the Marshall University Joan C. Edwards School of Medicine establishes a role of adipocyte Na/K-ATPase signaling in worsening obesity and its companion diseases, including neurodegeneration and non-alcoholic steatohepatitis (NASH), that was enhanced by specific targeting of NaKtide, an antagonist of Na/K-ATPase signaling, to the adipocyte.

Researchers at the University of Tokyo have devised a method for following the gelation of colloidal gels. Their confocal microscopy technique has allowed the different stages of the process to be analyzed, leading to insights into their mechanical stability. It is hoped that the understanding gained using this technique will contribute to the development of colloidal gels in the many fields in which they impact everyday lives, from pharmaceuticals to construction.

Can cannabinoids help treat obsessive-compulsive disorder?

The body's endocannabinoid system, due to the critical role it plays in regulating neurotransmitter signaling, is an enticing target for drug development against disorders associated with anxiety, stress, and repetitive behaviors, such as obsessive-compulsive disorder (OCD). A comprehensive new review article that provides an overview of this complex system, endogenous and exogenous cannabinoids, results of animal studies and human trials to date, and recommendations for future directions is published in Cannabis and Cannabinoid Research.

Research proves Midwestern fish species lives beyond 100 years

Research recently completed at North Dakota State University has proven that the Bigmouth Buffalo (Ictiobus cyprinellus), a fish native to North America, lives more than eight decades longer than previously thought. The study published in Communications Biology documents several individuals more than 100 years of age, with one at 112 years, which more than quadruples all previous age estimates for this species. In addition, many populations were documented to be 85-90% comprised of individuals more than 80 years old, suggesting unsuccessful reproduction since the 1930s. The Bigmouth Buffalo is now known as the longest-lived freshwater teleost (a group of approximately 12,000 species) and the oldest age-validated freshwater fish (a group of about 14,000 species).

Researchers discover a new way to protect against high-dose radiation damage

Radiotherapy is one of the most effective ways to destroy cancer cells and shrink tumors. Around 50 percent of patients with tumors located in the gastrointestinal cavity (liver, pancreas, colon, prostate, etc) receive this type of treatment, which has increased cancer survival rates in recent decades. However, intensive radiation therapy not only damages tumor cells, but also healthy intestinal cells, leading to toxicity in 60 percent of treated patients. Whereas reversal of toxicity is observed after radiotherapy has concluded, 10 percent of treated patients develop gastrointestinal syndrome, a disease characterized by intestinal cell death, resulting in the destruction of the entire intestine and patient death.

Microbes on explanted pedicle screws: Possible cause of spinal implant failure

Pedicle screws are often used to secure surgically implanted hardware to the spine in patients with spinal disease or spinal trauma. In some cases, these screws loosen over time, leading to spinal instability and consequent pain. This is a common complication of spine surgery. One reason suggested for pedicle screw loosening is implant-associated infection, but until now there has been little clinical evidence to support this theory.

The Standard Model is a remarkably successful but incomplete theory.

For example, sleptons are the spin 0 superpartners of spin 1/2 electrons, muons and tau leptons, while charginos and neutralinos are the spin 1/2 counterparts of the spin 0 Higgs bosons (SUSY postulates a total of five Higgs bosons) and spin 1 gauge bosons.

At current drug prices, testing all persons entering prison for Hepatitis C, treating those who have at least 12 months remaining in their sentence, and linking individuals with less than 12 months in their sentence to care upon their release would result in improved health outcomes.

While cost-effective, however, the data also show that these approaches would place a large cost burden on the correctional system.

Just like toothpaste: Fluoride radically improves the stability of perovskite solar cells

Solar cells made of perovskite hold much promise for the future of solar energy. The material is cheap, easy to produce and almost as efficient as silicon, the material traditionally used in solar cells. However, perovskite degrades quickly, severely limiting its efficiency and stability over time. Researchers from Eindhoven University of Technology, energy research institute DIFFER, Peking University and University of Twente have discovered that adding a small amount of fluoride to the perovskite leaves a protective layer, increasing stability of the materials and the solar cells significantly. The solar cells retain 90 percent of their efficiency after 1000 hours operation at various extreme testing conditions. The findings are published today in the leading scientific journal Nature Energy.

New clinical research supported by the National Institutes of Health shows that increasing the intensity of treatment for alcohol use disorder (AUD) over time improves alcohol-related outcomes among people with HIV. This stepped approach to AUD treatment also improves HIV-related disease measures in this patient population. A report of the new study, led by researchers at Yale University, is now online in The Lancet HIV.

Ernst Haeckel: Pioneer of modern science

"By ecology, we understand the whole science of the organism's relationship with the surrounding outside world, which includes in a broader sense all 'existential conditions'. These are partly organic and partly inorganic in nature; both the former and the latter are, as we have previously shown, of utmost importance for the form of the organisms, because they force them to adapt to them."

Dangerous pathogens use this sophisticated machinery to infect hosts

Gastric cancer, Q fever, Legionnaires' disease, whooping cough—though the infectious bacteria that cause these dangerous diseases are each different, they all utilize the same molecular machinery to infect human cells. Bacteria use this machinery, called a Type IV secretion system (T4SS), to inject toxic molecules into cells and also to spread genes for antibiotic resistance to fellow bacteria. Now, researchers at Caltech have revealed the 3-D molecular architecture of the T4SS from the human pathogen Legionella pneumophila with unprecedented details. This could in the future enable the development of precisely targeted antibiotics for the aforementioned diseases.

Manipulating superconductivity using a 'mechanic' and an 'electrician'

In strongly correlated materials such as cuprate high-temperature superconductors, superconductivity can be controlled either by changing the number of electrons or by changing the kinetic energy, or transfer energy, of electrons in the system. Although a large number of strongly correlated materials have been examined with different parameters to understand the mechanism of superconductivity, the range of parameter control is always limited. A versatile experimental method to achieve simultaneous control of the number and the transfer energy of the electrons has been long desired.
