Mechanisms explaining positional diversity of the hindlimb in tetrapod evolution

Jue, 08/17/2017 - 22:00
Elucidating how body parts in their earliest recognizable form are assembled in tetrapods during development is essential for understanding the nature of morphological evolution. Nagoya University researchers found in eight tetrapod species that the position of the sacral vertebrae and the hindlimbs is determined by the initiation timing of Gdf11 gene expression. This will contribute to a forthcoming model explaining the coupling of spine and hindlimb positioning - a major step in fully understanding tetrapod evolution.

Scientists from the MSU studied new liquid-crystalline photochrom

Jue, 08/17/2017 - 22:00
Members of the Faculties of Chemistry and Fundamental Physical and Chemical Engineering at the Lomonosov Moscow State University in collaboration with foreign partners have synthesized and studied new liquid-crystal photochromic polymers. The research has been fulfilled within the framework of the project, funded by the Russian Science Foundation.

Organ crosstalk: Fatty liver can cause damage to other organs

Jue, 08/17/2017 - 22:00
Scientists of the German Center for Diabetes Research (DZD) in Tübingen discovered that a fatty liver can cause damage to other organs. In two just-published studies they demonstrate the effects of fatty liver disease on the function of the hormone-producing islet cells in the pancreas and on renal function.

Vitamin D deficiency linked to increased heart failure risk in older adults

Jue, 08/17/2017 - 22:00
A recent study found an elevated risk of heart failure in more than half of older individuals, and this risk was significantly associated with vitamin D deficiency.

Researchers from the University of Freiburg are mapping the distribution of all proteins in mitochondria for the first time.

Researchers discover new chemical process that could reduce nitrogen oxides from diesel exhaust

Jue, 08/17/2017 - 22:00
Chemical engineers at the University of Notre Dame have discovered a catalytic process that could help curb emissions of nitrogen oxides from diesel-powered vehicles, a priority air pollutant that is a key ingredient in smog.

Population health impact of infants born small for gestational age in low- and middle-income countries

Jue, 08/17/2017 - 22:00
Researchers at Brigham and Women's Hospital and CHERG used the first international, multi-ethnic birth weight standard, known as the INTERGROWTH-21st, to describe the global burden of suboptimal fetal growth.

Special issue of Future Medicinal Chemistry explores immunotherapy edit article

Jue, 08/17/2017 - 22:00
The field of immunotherapy is moving forward at an unprecedented rate and cancer immunotherapy, in particular, has recently come of age!

Virus with an eggshell

Jue, 08/17/2017 - 22:00
Avian flu can be transmitted from birds to humans; transmission among humans, however, is limited. The reason may be an eggshell-like mineral layer that the virus acquires due to the high calcium concentration in the intestines of birds. As reported by Chinese researchers in the journal Angewandte Chemie, these mineralized viruses are significantly more infectious and, in addition, more robust and heat stable than the native viruses.

Artificial neural networks decode brain activity during performed and imagined movements.

Flexibility at work key to helping women maintain careers after childbirth

Jue, 08/17/2017 - 22:00
Flexibility in the workplace is the key to helping women maintain their career trajectory after childbirth, new research by the University of Kent has shown.

New study rebuts the claim that antidepressants do not work

Jue, 08/17/2017 - 22:00
A theory that has gained considerable attention in international media, including Newsweek and the CBS broadcast 60 minutes, suggest that antidepressant drugs, such as the SSRIs, do not exert any actual antidepressant effect. A research group at the Sahlgrenska Academy has now analyzed data from clinical trials and can rebut this theory.

The power of perovskite

OIST researchers improve perovskite-based technology in the entire energy cycle, from solar cells harnessing power to LED diodes to light the screens of future electronic devices and other lighting applications.

How whip-like cell appendages promote bodily fluid flow

Jue, 08/17/2017 - 22:00
Researchers at Nagoya University revealed that a molecule called Daple is essential for the correct orientation and coordinated beating of cilia on the surface of cells lining ventricles in the brain. Without Daple, the cilia develop a random arrangement and cannot produce a uniform flow of CSF. This in turn leads to a build-up of fluid, which is associated with swelling of the head, known as hydrocephalus.

Drug resistance in an intestinal parasite of piglets confirmed for the first time

Jue, 08/17/2017 - 22:00
Cystoisospora suis causes diarrhea especially in newborn piglets and spreads quickly across farms. European farmers preventively use toltrazuril to control parasite development. In contrast to congeneric chicken parasites, no resistance to toltrazuril was described in pig parasites until recently. Researchers of Vetmeduni Vienna now confirmed ineffectivness of toltrazuril against a Dutch isolate. Although the resistance develops slowly, monitoring should be intensified due to the lack of alternative treatment options and hygiene measures should be increased.

Initial preliminary assessment of the health risks posed by longer-term consumption of foods contaminated with fipronil

Jue, 08/17/2017 - 22:00
Based on currently available knowledge, the German Federal Institute for Risk Assessment (BfR) assumes that illegal applications of products containing fipronil have apparently been carried out over an extended period of time. For this reason, the longer term consumption of foods contaminated with fipronil has to be given due consideration when assessing the risks.

Lasers used to detect risk of heart attack and stroke

Jue, 08/17/2017 - 22:00
Patients at risk of heart attacks and strokes may be spotted earlier thanks to a diagnosis tool that uses near-infrared light to identify high-risk arterial plaques, according to research carried out at WMG, University of Warwick, the Baker Institute and Monash University.

Hypertension during pregnancy may affect women's long-term cardiovascular health

Jue, 08/17/2017 - 22:00
Women who experience hypertension during pregnancy face an increased risk of heart disease and hypertension later in life, according to a new study.

A heart made of spider silk

Jue, 08/17/2017 - 22:00
Ever more people are suffering from cardiac insufficiency. The main cause of reduced cardiac functionality lies in the irreversible loss of cardiac muscle cells due to disease, especially ischemic diseases such as cardiac infarction. There is still no treatment to reverse damage of this nature. Research is ongoing to develop methods of repairing such damage to normalize cardiac function. A promising approach: cardiac muscle tissue made of spider silk.

Fipronil in foods containing eggs: Estimations of maximum tolerable daily consumption

Jue, 08/17/2017 - 22:00
The German Federal Institute for Risk Assessment has prepared a health risk assessment based on limited available data on fipronil levels in foods (containing eggs) in Germany.
