The geometry of histamine understood by Russican scientists

The geometry of histamine understood by Russican scientists

A group of scientists from Lomonosov Moscow State University studied histamine molecules in the gas phase using an electron beam. The study used both experiment and calculations. This work was published in Physical Chemistry Chemical Physics journal (impact factor of 4.493) of Royal Society of Chemistry (UK). Authors are employees of Division of Physical Chemistry (Chemistry Department of Lomonosov MSU), specializing in particular on the study of bioactive compounds and medicines.

The mystery of the Red Sea

The mystery of the Red Sea

The Red Sea is known as one of the best tourist destinations for good relaxation and scuba-diving, but no one can even imagine that this place is inhabited by many sea creatures that are still waiting to be discovered. An international team of biologists, which included researchers from the Lomonosov Moscow State University and the Shemyakin-Ovchinnikov Institute of Bioorganic Chemistry of the Russian Academy of Sciences, found and explored a new kind of beautiful luminous creatures.

Study suggests more effective speech therapy approach for children with Down syndrome

Study suggests more effective speech therapy approach for children with Down syndrome

A new study indicates that children with Down syndrome who have motor speech deficits have been inadequately diagnosed, which could have a major impact on the interventions used by speech pathologists when treating patients.

New tool for efficiently validating the accuracy of CRISPR-Cas9 reactions

New tool for efficiently validating the accuracy of CRISPR-Cas9 reactions

CRISPR-Cas9's popularity continues to grow ever since its first use in genome editing in January, 2013. What makes CRISPR-Cas9 so remarkable is its astonishing efficiency and availability; relatively speaking, it is easy to use. Last year, scientists at the Center for Genome Engineering within the Institute for Basic Science (IBS) published a paper in Cell Stem Cell describing how they corrected an inverted gene sequence which effectively cured a type of Hemophilia. The Jin-Soo Kim group at IBS has also used CRISPR-Cas9 to perform a process without using foreign DNA to modify crops.

Motorboat noise gives predators a deadly advantage

Motorboat noise gives predators a deadly advantage

A pioneering new study shows the rate fish are captured by predators can double when boats are motoring nearby.

Professor Mark McCormick of the ARC Centre of Excellence for Coral Reef Studies at James Cook University was part of an international research team that found noise from passing motorboats increases stress levels in young coral reef fish and reduces their ability to flee from predators. As a consequence they are captured more easily and their survival chances are halved.

Prunetin prolongs lifespan in male fruit flies and enhances overall health

Here's a reason for men to eat their lima beans--If research in male fruit flies holds up, it might help you live longer. A new research report published in the February 2016 issue of The FASEB Journal, shows that administering an oral dose of prunetin to male fruit flies extends lifespan, increases fitness levels, and improves their glucose balance. This effect was not found in females. Prunetin is a plant-derived compound that belongs to the isoflavone group.

Fecal analyses may lead to noninvasive diagnostics for inflammatory bowel disease

New research indicates that analyses of vapors from fecal samples can identify volatile metabolites indicative of different types of inflammatory bowel disease, including Crohn's disease and ulcerative colitis.

The findings, which come from a study of fecal samples from 117 people with Crohn's disease, 100 with ulcerative colitis, and 109 healthy controls, suggest that the technique might be useful as a non-invasive screening test that could allow earlier diagnosis of such conditions.

This study is published in Alimentary Pharmacology & Therapeutics.

Management style affects quality of care and retention among nurses

A recent study shows that encouraging nurses to work towards a collective goal within a supportive milieu--a style of management called transformational leadership--can have positive effects on the quality of the care given to patients. It was also a predictor of nurses' intentions to stay on at their current healthcare facilities. Conversely, abusive leadership practices potentially lead to poorer quality of care and to a strong intention to quit.

Kaiser Permanente study finds effectiveness of routine Tdap booster wanes in adolescents

OAKLAND, Calif., February 5, 2016 -- A new study from Kaiser Permanente's Vaccine Study Center found that the Tdap booster vaccine provides moderate protection against whooping cough during the first year after vaccination, but its effectiveness wanes to less than 9 percent after four years among teenagers who have received only a newer form of the whooping cough vaccine (acellular pertussis vaccine) as infants and children. These findings were published today in Pediatrics.

Snake gait

It has no wheels or legs or anything to help itself along, and yet it is able to move and to move quite fast. In terms of mobility, the snake is a masterpiece of engineering, and it is no coincidence that it should be studied to uncover the physics underlying its locomotion.
