Recombinant adenovirus-mediated DHCR24 inhibits neural apoptosis

Recombinant adenovirus-mediated DHCR24 inhibits neural apoptosis
2014-08-22
(Press-News.org) 3β-Hydroxysteroid-Δ24 reductase (DHCR24) is a multifunctional enzyme that localizes to the endoplasmic reticulum and has neuroprotective and cholesterol-synthesizing activities. DHCR24 overexpression confers neuroprotection against apoptosis caused by amyloid β deposition. Dr. Xiuli Lu and colleagues from Liaoning University in China constructed two recombinant adenoviruses (Ad-rSYN1-DHCR24-myc and Ad-hSYN1-DHCR24-myc) that drive DHCR24 expression specifically in neuronal cells. They also found that adenovirus transfection inhibits apoptosis through scavenging excess reactive oxygen species. In summary, these researchers have for the first time successfully constructed an adenovirus that induces DHCR24 specifically in neuronal cells. These findings published in the Neural Regeneration Research will lay the foundation for further studies on DHCR24 gene therapy and neuronal functional research in animal models.

Smokers consume same amount of cigarettes regardless of nicotine levels

Smokers consume same amount of cigarettes regardless of nicotine levels
2014-08-22
Cigarettes with very low levels of nicotine may reduce addiction without increasing exposure to toxic chemicals, according to a new study from the University of Waterloo. The study published in the journal Cancer Epidemiology monitored the smoking behaviours of 72 adults as they switched to three types of cigarettes with markedly reduced nicotine levels. Unlike when smokers switch between conventional cigarette brands—all of which have very similar levels of nicotine content—the study found no change in participants' puffing behaviour, number of cigarettes consumed ...

Spectacular supernova's mysteries revealed

2014-08-22
New research by a team of UK and European-based astronomers is helping to solve the mystery of what caused a spectacular supernova in a galaxy 11 million light years away, seen earlier this year. The supernova, a giant explosion of a star and the closest one to the Earth in decades, was discovered earlier this year by chance at the University of London Observatory. These phenomena are extremely important to study because they provide key information about our universe, including how it is expanding and how galaxies evolve. The new research into its cause, published ...

Citizen scientists saving lives around deadly 'Throat of Fire' volcano

Citizen scientists saving lives around deadly Throat of Fire volcano
2014-08-22
Citizen scientists are saving the lives of people living in the shadow of deadly volcanoes according to new research from the University of East Anglia. A new report published today reveals the success of a volunteer group set up to safeguard communities around the 'Throat of Fire' Tungurahua volcano in the Ecuadorian Andes. More than 600 million people live close to active volcanoes worldwide. The research shows that living safely in these dangerous areas can depend on effective communication and collaboration between volcanologists, risk managers and vulnerable communities. It ...

Stanford scientists develop a water splitter that runs on an ordinary AAA battery

Stanford scientists develop a water splitter that runs on an ordinary AAA battery
2014-08-22
In 2015, American consumers will finally be able to purchase fuel cell cars from Toyota and other manufacturers. Although touted as zero-emissions vehicles, most of the cars will run on hydrogen made from natural gas, a fossil fuel that contributes to global warming. Now scientists at Stanford University have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis. The battery sends an electric current through two electrodes that split liquid water into hydrogen and oxygen gas. Unlike other water splitters ...

Genetics and lifestyle have a strong impact on biomarkers for inflammation and cancer

2014-08-22
In a new study published in Nature Communications, research scientists from Uppsala University present for the first time a large-scale study of the significance of genetic, clinical and lifestyle factors for protein levels in the bloodstream. The results of the study show that genetics and lifestyle are determining factors for protein levels, a discovery which greatly influences the possibilities for using more biomarkers to identify disease. Biomarkers used for diagnosing disease should preferably indicate variations in protein levels only for those individuals who ...

Calcium and reproduction go together

2014-08-22
Stanford, CA—Everyone's heard of the birds and the bees. But that old expression leaves out the flowers that are being fertilized. The fertilization process for flowering plants is particularly complex and requires extensive communication between the male and female reproductive cells. New research from an international team from Stanford, Regensburg, Heidelberg, and Munich, and including Carnegie's Wolf Frommer, David Ehrhardt, and Guido Grossmann reports discoveries in the chemical signaling process that guides flowering plant fertilization. It is published in Nature ...

Fossil arthropod went on the hunt for its prey

2014-08-22
A new species of carnivorous crustacean has been identified, which roamed the seas 435 million years ago, grasping its prey with spiny limbs before devouring it. The fossil is described and details of its lifestyle are published in the open access journal BMC Evolutionary Biology. The fossils were discovered near Waukesha, Wisconsin, with the new species, Thylacares brandonesis, named after the Brandon Bridge Formation where it was found. It is the oldest known example of the Thylacocephala group - shrimp-like creatures, mostly from the Jurassic period, known for their ...

Climate change could see dengue fever come to Europe

2014-08-22
Dengue fever could make headway in popular European holiday destinations if climate change continues on its predicted trajectory, according to research published in open access journal BMC Public Health. The University of East Anglia study used current data from Mexico, where dengue fever is present, and information about EU countries in order to model the likelihood of the disease spreading in Europe. They found that coastal regions in around the Mediterranean and Adriatic seas, the Po Valley and North East Italy were most at risk. Dengue fever is a tropical disease ...

Effort to confront Africa's soil health crisis helps millions of farmers triple yields

2014-08-22
This news release is available in French. NAIROBI (22 August 2014)—With the steady drain of essential nutrients from African soils looming as a major threat to food security across the continent, a new report released today finds that over the last five years, 1.7 million African farmers in 13 countries have embraced farming practices that have rejuvenated 1.6 million hectares and helped them double or even triple crop yields. The analysis from the Alliance for a Green Revolution in Africa (AGRA) focuses on intensive efforts initiated five years ago to move aggressively ...

Coronary calcium predicts heart disease risk in patients with chronic kidney disease

2014-08-22
Washington, DC (August 21, 2014) — Calcium buildup in the coronary arteries may be a better indicator of kidney disease patients' risk of heart disease than traditional risk factors used in the general population, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). The findings provide valuable new information that could help safeguard the heart health of patients with kidney disease. Heart disease is the leading cause of death in individuals with chronic kidney disease (CKD). Some studies have found that conventional ...
