Blood test may help signal tumor's remission, return in throat cancer patients

...amount of blood was required for the test. The majority of the patients had a complete response to therapy. Patients whose blood levels of these cytokines and growth factors dropped and remained low following treatment were more likely to continue in remission. Patients who experienced large increases in ...

Liver cancer patients with high serum levels of hepatitis B virus face poorer outcomes

...is endemic, like China and the Far East, the great majority of cases of hepatocellular carcinoma (HCC) occur in individuals with the virus. For most patients whose cancer is inoperable, chemotherapy is one of the main treatment options, and still the prognosis is dismal. Survival is often measured in months. ...

Old memory traces in brain may trigger chronic pain

...population suffers from chronic pain, of which the majority is back pain. One of Apkarian’s studies with rats tried to separately measure their emotional suffering and their physical pain after being treated with the drug. (The rats had chronic pain from a healed limb injury.) The results indicated the an...

Dirty snow may warm Arctic as much as greenhouse gases

...g soot; clouds; and land use. Humans create the majority of airborne soot through industry and fuel combustion, while forest and open-field fires account for the rest. Because of human activity, greenhouse gas levels have increased by one-third in the last two centuries. “A one-third change in concentra...

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

...e PfCRT gene is primarily responsible for the vast majority of drug resistance that leads to human death from malaria. Earlier this year, they also helped describe how the gene PfNHE likely contributes, and this turns out not to be as vital as PfCRT. Now, based in part on this study, they know that PfMDR1 is ...

New collaborative research reveals chimpanzees can sustain multiple-tradition cultures

... of its own group complete an action sequence, the majority of the chimpanzees followed that sequence for the remainder of the testing period. Over time, the different methods chosen by each high-ranking female were passed among members of her group, thereby becoming a local tradition. In all, the researc...

Rising skin cancer rates are more likely to affect wealthy people, says 12-year review

...cent, with a 62 per cent rise in samples. “The majority of the people who live in Northern Ireland have fair skin and the 2001 census revealed that less than one per cent of the population belongs to a black or minority ethnic group” adds co-author Dr Olivia Dolan, consultant dermatologist at the Royal Vi...

Study investigates 'divorce' among Galapagos seabirds

...nd 700 females in the study. During that time, the majority of the females in this group gambled on a new mate, sometimes one that had never bred before. This is one of the few studies that addresses divorce in successfully breeding bird pairs, Maness said. “This study really predicts that the probability...

New findings challenge established views on human genome

...um’s major findings include the discovery that the majority of DNA in the human genome is transcribed into functional molecules, called RNA, and that these transcripts extensively overlap one another. This broad pattern of transcription challenges the long-standing view that the human genome consists of a rel...

Human genetic 'deserts' are teeming with significant life

...eva, Geneva, Switzerland. “We found that the vast majority of the protein coding genes we studied utilised often in a tissue-specific manner previously unknown set of exons [the regions of DNA within a gene that are transcribed to messenger RNA] outside the current boundaries of the annotated genes ”, Profe...

New vaccine prevents CMV infection and disease in mice

...mans. CMV is a virus that, while carried by the majority of adults in the United States, can remain dormant for years, if not the lifetime, of a healthy individual. However, two percent of all children are born with the virus passed on by the mother in utero, and 15 percent of those children will show sym...

Ants show us how to make super-highways

...ity can significantly improve the performance of a majority to benefit the group as a whole. It also suggests that these benefits are a consequence of the unusual and derived foraging strategy of the army ant (Eciton burchellii). This highlights the importance of considering ecology and evolutionary history i...

Researchers use MRI to predict recovery after spinal cord injury

...dmission. One patient could not be classified. The majority of the patients had been injured in motor vehicle accidents. MRI exams were obtained within 24 to 48 hours of injury. The research team studied three measurable imaging parameters: maximum spinal cord compression (MSCC), maximum canal compromise (...

Human stem cell treatment restores motor function in paralyzed rats

... In all the rats grafted with the stem cells, the majority of transplanted human spinal stem cells survived and became mature neurons, according to Marsala. A second study was conducted over a three-month period, with similar results. “Other human stem cell transplants in the spinal cord have focused on r...

Risk of lymphoma increases with hepatitis C virus infection

... study population was mostly men (97 percent), the majority of patients were white, and the average age was 52 years. Patients in the HCV-infected group were more likely to have served during the Vietnam era (1964-1975) than were uninfected patients in the comparison group. Previous studies found that t...

LIAI scientists make important finding on cytomegalovirus transmission

...D. led the study. CMV is a virus that affects the majority of the world’s population, but produces little or no symptoms in healthy individuals. However, it can cause multi-organ disease in newborns or persons who are immuno-compromised such as organ transplant recipients or AIDS patients. Ware said, "Th...

Toxoplasmosis infection trick revealed by scientists

Researchers publish first marsupial genome sequence

...sts made two major findings: First, the vast majority (about 95 percent) of recent genetic innovation lies not in protein-coding genes, but in regions of the genome that do not contain genes and that many had referred to as junk DNA until recently. Researchers now know that junk DNA may contain regulato...

Genome of yellow fever/dengue fever mosquito sequenced

...e of the malaria mosquito genome. "Although the majority of protein coding TE copies in Ae. aegypti appear to be degenerate, a significant number of elements have potentially active TE copies, indicating that they may be developed as tools for genetic studies of mosquitoes," Tu said. "If you look at th...
