NJIT Presidential Award winner takes stem cell research another step

... therapy." Arinzeh's first stem-cell breakthrough focused on developing scaffolds that aid stem cells. She performed animal studies on rats with bone defects; she also did cell-culture studies. Both showed that the biomaterials stimulated stem cells, producing new bone tissue and fully repairing the rats' b...

New methods of gene delivery using lasers

... The new technique involves the violet laser being focused onto cell membranes for a fraction of a second ?this causes the membrane to open up, allowing foreign genes to enter. The cell’s internal mechanism causes the membrane of the cell to heal itself thus appearing to suffer no long-lasting damage. After ...

Boosting HIV screening can increase survival and is cost effective

...s, yet current approaches to HIV testing are still focused on these sub-populations. The result is that 280,000 Americans with HIV remain unaware of their infection. Efforts to promote and finance routine, population-based HIV screening should be pursued aggressively." Douglas K. Owens, M.D., of the VA Palo...

Measuring the impact of post-genomics on Mediterranean populations

...esearch. The second day of the workshop (5 March) focused more closely on health research in the context of the EU-MPC partnership. Michel Pletschette, representing the Research Directorate-General, which helped support the event, gave an overview of the EU-MPC programme: its past, present and future. Round...

Self-assembled nano-sized probes allow Penn researchers to see tumors through flesh and skin

...ntage of years of effort in the Therien laboratory focused on the design of highly fluorescent compounds. Polymersomes, which were developed by Penn professors Daniel A. Hammer and Dennis Discher in the mid-1990s, function much like the bilayered membranes of living cells. Whereas cell membranes are created ...

Chemists identify key gene in development of type 1 diabetes

...ic society. In the current study, the researchers focused on the formation of the MIF protein (macrophage migration inhibitory factor), a proinflammatory protein that they showed in previous studies is elevated in diabetic animals and may be involved in the cascade of immunological events that leads to the ...

Towards precise classification of cancers based on robust gene functional expression profiles

...ic society. In the current study, the researchers focused on the formation of the MIF protein (macrophage migration inhibitory factor), a proinflammatory protein that they showed in previous studies is elevated in diabetic animals and may be involved in the cascade of immunological events that leads to the ...

Children's taste sensitivity and food choices influenced by taste gene

...out food. Mennella comments, "Our previous studies focused on how early experience influences preferences for foods and flavors. Now, we have a tool to look at how experience and genetics interact in determining why we like the foods we do." Monell researcher M. Yanina Pepino also contributed to the study. ...

Researchers develop rapid diagnostic tool for pathogen identification

...g the time needed for differential diagnosis. “We focused first on respiratory diseases because differential diagnosis is a common clinical problem with implications for outbreak control and individual case management,?stated W. Ian Lipkin, MD, Jerome L. and Dawn Greene Professor of Epidemiology and profess...

Asthma gene clusters identified

...hildhood asthma, she said. This study exclusively focused on genes associated with epithelial cells. Genes associated with mucosa and underlying cells are likely to be involved as well. Dr. Hershey is expanding her research in cooperation with the Computational Medicine Center (CMC), a research partnership...

Use of Insecticides Linked to Lasting Neurological Problems for Farmers

...farmers. It's different from previous studies that focused on pesticide poisoning or high dose exposures, for example when large amounts of a chemical were accidentally spilled on the skin," said Freya Kamel, Ph.D., a researcher for the National Institute of Environmental Health Sciences (NIEHS). The NIEHS ...

Drug-resistant bacteria on poultry products differ by brand

...cs and from those who claim they do not. The study focused on antibiotic resistance, specifically fluoroquinolone-resistance in Campylobacter, a pathogen responsible for 2.4 million cases of food-borne illness per year in the U.S., according to the Centers for Disease Control and Prevention. The study is pub...

Researchers discover molecular mechanism that desensitizes us to cold

...advance online publication by Nature Neuroscience, focused on a specific region of the cold receptor which is found in many other receptors, including ones involved in taste, vision and fertilization. Therefore, the findings may have important implications across a wide range of areas. Diomedes Logothetis, ...

Pulsating ultrasound enhances gene therapy for tumors

High-intensity focused ultrasound emitted in short pulses is a promising,...ay issue of the journal Radiology. High-intensity focused ultrasound (HIFU) is more powerful than standard ultrasound. HIFU can destroy tumors through long an...

New winter hulless barley has high protein

...gram work is aimed at reversing this trend. It has focused on improving and diversifying barley's end-use quality. "Traditional hulled barley cultivars that have higher starch and energy content, therefore, better feed quality, such as cultivars named 'Thoroughbred' and 'Price,' have recently been released ...

Researchers find new genes necessary to make embryo

... genes are required to make an embryo. Their study focused on the genes expressed by the mother and imparted to the egg, ready to be used during the earliest stages after fertilization. They discovered over 150 additional genes required to make an embryo beyond what was previously known, leading them to conc...

Nanoparticles offer new hope for detection and treatment

...n or chemotherapy treatments. Although this study focused on melanoma tumors, the researchers believe the technology should work for most solid tumors, because all tumors must recruit new blood vessels to obtain nutrients as they grow. Nevertheless, melanoma has unique traits that make it especially intere...

Disease diagnosis, biodefense among UH chemical research projects

...rption in lung tissue. Czernuszewicz's research is focused on the roles of salivary nitrophorins in storing and releasing NO and binding histamine by using resonance Raman spectroscopic techniques as a probe of molecular structure. # Yuriy Fofanov, assistant professor of computer science and assistant profe...

Brain-mapping technique aids understanding of sleep, wakefulness

...ulating sleep." Dr. Yanagisawa and his colleagues focused on neurons in the brain that produce the protein orexin, which helps keep animals awake. In humans, a lack of, or deficiency in, orexin causes narcolepsy, a rare disease in which people uncontrollably fall asleep, have excessive daytime sleepiness an...

Emergence of cancer as major cause of childhood death in developing countries is not being adequately addressed
