Novel Device Developed To Help Autistic Individuals Communicate Better

...n signals the wearer through a vibratory movement, signaling that the listener is not involved. The researchers had previously demonstrated at the University of Cambridge that her software is capable of detecting emotions associated with agreement, disagreement, concentration, thought and level of interest o...

Unchecked Cellular Repair Pathway Causes Liver Cancer

...l of Medicine have found that an uncontrolled cell signaling pathway that plays a vital role in the embryonic development and the liver's own response // to injury lead to the development of liver cancer. The cell-signalling pathway called Hedgehog is present only in immature, stem-like liver cells. This dis...

Malfunction Of Key Growth Factor Increases Mortality Rate From Pulmonary Fibrosis In Blacks

...differences in the c-Met function due to damage or signaling difficulties and the results could give us some useful clues." She said it's also possible "now that we know what to study, that further work on scleroderma itself will be more productive. It's a little simpler disease, and since PF develops from the...

Mouse Models To Determine The Cause Of Aggressive Leukemia

...nases. This later stimulates cell growth through a signaling pathway that operates alongside the one controlled by the Bcr-Abl kinase. The investigators used a chemical inhibitor of JAK kinases to block the effect of IL-7 on leukemic cells in culture which restored the ALL cells’ sensitivity to imatinib. In co...

Cholesterol Plays An Important Role In Finger and Toe Development

... that mutations in some part of the Sonic hedgehog signaling pathway could be responsible for the same. Sonic hedgehog signaling has been implicated in a number of birth defects such as deformities of spinal cord and brain (more ...

Stem Cell Technology Gives Hope in Spinal Cord Injuries

...e growth. . This led the Davies team to think of signaling cells similar to stem cells known as the glial-restricted precursors, or GRPs, to become a particular type of embryonic astrocyte which was considered to have a remarkable ability of repairing embryonic spinal cord. This in turn was considered for t...

Study Highlights Appetite Regulation Pathway, New Hope for Weight Loss

Researchers have now identified a signaling pathway in the brain, which has been found a cruci...'s Genome Research Institute demonstrated that the signaling pathway mTOR--activated by nutrient and hormonal signals--plays a role in the brain's ability to sen...

C-Myc Gene Essential for Immune System Function

... as an oncogene, that acts downstream of the IL-15 signaling pathway to regulate T memory cell homeostasis.’ According to Dr. MacDonald, the study is basic research that may have implications for therapies of the future. ‘Understanding how immune memory works might allow us to improve therapeutic vaccines ag...

Discovery Of New Molecule Could Solve Cancer Spread Mystery

...ad reactivity to effectively attenuate the complex signaling pathways involved in malignant transformation and ...gh both of these molecules are members of the same signaling cascade, the researchers found that they must be concurrently inhibited because of a regulatory feed...

Birth Defects Caused By Deficiencies In Cell Signaling Pathway

Cell signaling pathways are particularly essential for proper embryo development and disorders in these cellular pathways// can lead to birth defects such as cleft palate, spina bifida, reports a new study. The research is a collaborative effort of the University o...

Study Highlights How Bacteria Respond To Changes In Environment

... in fact point to a general mechanism for cellular signaling and serve as inspiration for developing molecular devices. Such devices could be used to sense a wide range of chemicals, light, ionic strength (salt), pH and heavy metals with great sensitivity, gain and dynamic range. Scientists are interested in d...

Placental Protein Leads To The Onset Of Preeclampsia - Researcher Finds

...factor beta,’ explains Karumanchi. ‘The diminished signaling of these growth factors in the vasculature adversely affects the health of the mother’s small blood vessels.’ The result is the onset of preeclampsia and its dangerous consequences for both mother and infant. ‘We believe that these latest findings ...

Protein’s role in regulating cell death sets direction for Alzheimer’s, Parkinson’s and cancer reseach

... activation of AKT and JNK, two key players in the signaling pathways that control cellular responses to different death stimuli. These discoveries suggest that calpain inhibitors might improve the ability of chemotherapeutic drugs or radiation treatment to specifically kill tumour cells in cancer patients. (...

Schizophrenia Complicates With Altered Receptor Activity

...ceptor groups,’ explains Hahn. ‘Altered NRG1-erbB4 signaling may contribute to NMDA receptor hypofunction in schizophrenia.’ This finding is the first to display NMDA receptor hypofunction in the brains of patients with schizophrenia. ErbB4 and NMDA receptors are located at the post-synaptic junction, or the...

Link between Obesity and Post-Radiotherapy Outcome in Prostate Cancer Patients
