Robotic therapy helps restore hand use after stroke

...x to another in one minute. The patients also developed a 17 percent greater range of motion in their hands and wrists and were rated as less disabled on a standard occupational therapy assessment tool called the Fugl-Meyer score. __IMAGE_3 "Assessing changes in before-and-after scores within each su...

In-shell vaccine for chick disease

...cine virus which provides immunity to IBV has been developed by scientists at the Institute for Animal Health (IAH) and vaccine company Intervet UK. It can be delivered to chicks still in the egg (in-ovo) using robotic 'vaccinators'. IBV is the worst infectious disease in terms of economic loss to the UK p...

New protein inhibitor impedes growth of cancerous cells

Researchers have developed a small-molecule inhibitor of a protein that plays key roles in the control of cell division, and they show that the inhibitor can halt the growth of tumors in mice and cancer-derived cells growing in culture. The findings are reported in companion p...

A rarity among arachnids, whip spiders have a sociable family life

...e used to capture prey. The first pair of legs has developed into long whiplike feelers that are three to four times longer than the remaining three pairs of legs. The exceptionally flexible whips can move 360 degrees around their bodies and are covered with hairs that sense their environment....

Technology reveals 'lock and key' proteins behind diseases

A new technology developed at the University of Toronto is revealing biochemical processes responsible for diseases such as cystic fibrosis and could one day pave the way for pharmaceutical applications. A study appearing in the April 13 issue of Molecular Cell describes how...

Molecular differences between early and advanced melanomas could provide new drug targets

...duced into immunocompromised (nude) mice, the mice developed aggressive tumors that expressed high levels of VEGF, whereas a control group of mice developed no tumors. Another result of Akt overexpression was the increased production of reactive oxygen ...

New mechanism for nutrient uptake discovered

...s a precursor to all known organisms on Earth, had developed this feature because there was much more ammonia on the early Earth. The ubiquitous presence of this structure in all of the known ammonium transporters suggests that the regulation is still necessary today for all of these organisms—cyanobacteria in...

Angelman syndrome deficits rescued in mice

... in a single gene, called UBE3A. They subsequently developed a mouse model of Angelman syndrome by mutating this gene. But the finding was baffling, said Weeber, because UBE3A is a "housekeeping" gene, meaning that it broadly regulates cellular processes not particularly specific for any of the neurological...

Antibody therapy prevents type 1 diabetes in mice

...ment of diabetes, whereas most of the control mice developed diabetes by the time they were six months old. ...ficient NOD mice, seven of the nine recipient mice developed type 1 diabetes, indicating that the donor mice still harbored pathogenic T-cells. On the other hand...

Research on grey mould offers possible breakthrough in tomato cultivation

Scientists clone mice from adult skin stem cells

...om the skin of mice. Using purification methods developed in Fuchs' Laboratory of Mammalian Cell Biology and Development, postdocs Valentina Greco and Géraldine Guasch isolated stem cells from the mice's hair follicles. They gave these stem cells to Jinsong Li, a postdoc in Rockefeller's Laboratory of Devel...

Insomnia drug can improve brain function

...chers conducted a study of a 48 year-old woman who developed akinetic mutism due to oxygen deprivation to her brain following an attempted suicide by hanging. The patient was totally dependent, unable to speak or walk, and was using a feeding tube for nourishment, although she was able to understand single wor...

Vasectomy may put men at risk for type of dementia

...In addition, the men who had undergone a vasectomy developed PPA at a younger age (58 years) than men with PPA who hadn't had one (62 years.) While PPA robs people of their ability to speak and understand language, an unusual twist of the disease is patients are still able to maintain their hobbies and perf...

Novel antigen-cloning technique may boost efforts to develop a melanoma vaccine

Keeping the body in sync -- The stability of cellular clocks

...researchers turned to dynamical systems theory and developed a mathematical model that identified the molecular parameters responsible for the stability of the cellular clocks. Stability is a measure of how fast the system reverts to its initial state after being perturbed. “To my knowledge we are the firs...

Tumor-suppressor gene is critical for placenta development

...author of the new paper. For this study, Wenzel developed a transgenic mouse that makes an enzyme that deletes DNA. Specifically, it removes the DNA that lies between two gene markers. She then used a second transgenic mouse in which the gene markers were placed in the Rb gene. When she crossed the two s...

Infection detectives use disease 'fingerprints' to track common infections in children

...spond differently to different infections. We have developed the tools to understand that," said Dr. Octavio Ramilo, professor of pediatrics at UT Southwestern and lead author of a study appearing in the March edition of the journal Blood . "Infectious diseases are the No.1 cause of death in the world. So ...

Scientists use nanoparticle to discover disease-causing proteins

...esence or absence of a protein that can be further developed for use as a disease indicator, or biomarker. Snake venom cells were used because they have a very high concentration of proteins similar to some found in human blood, Tao said. The proteins apparently are part of the biochemical process that affe...
