Clinical waste may be valuable for monitoring treatment response in ovarian cancer Posted: 06 Dec 2013 01:30 PM PST A microchip-based device developed may greatly simplify the monitoring of patients' response to treatment for ovarian cancer -- the most lethal form of gynecologic cancer -- and certain other malignancies. The team reports using their device to isolate and identify tumor cells from ascites, an accumulation of fluid in the abdomen that often occurs in abdominal cancers.

Researchers may have discovered a plan to disable Meniere's disease Posted: 06 Dec 2013 01:30 PM PST Researchers may have figured out what causes Meniere's disease and how to attack it: there is a strong association between Meniere's disease and conditions involving temporary low blood flow in the brain such as migraine headaches, their work indicates.

Calibration tools to encourage use of novel medical imaging technique Posted: 06 Dec 2013 01:30 PM PST Researchers have developed prototype calibration tools for an experimental medical imaging technique that offer new advantages in diagnosing and monitoring of certain cancers and possibly other medical conditions.

Decreased diversity of bacteria microbiome in gut associated colorectal cancer Posted: 06 Dec 2013 01:30 PM PST Decreased diversity in the microbial community found in the human gut is associated with colorectal cancer, according to a new study published.

U.S. malaria cases increase with international travel Posted: 06 Dec 2013 01:30 PM PST Researchers are looking for new ways to fight malaria through mosquito control. In 2011, 1,925 malaria cases were reported in the U.S., according to the Centers for Disease Control and Prevention (CDC). This number is the highest seen since 1971 and represents a 48 percent increase from 2008. The majority of malaria infections in the U.S. occur among people who have traveled to regions with malaria endemic.

To improve foster care, add psychiatric nurse to treatment team Posted: 06 Dec 2013 01:29 PM PST A nursing instructor has found mental health nurses lend valuable perspective in treating troubled teens in foster care.

Cancer-promoting protein is vital to safe division of tumor cells Posted: 06 Dec 2013 01:29 PM PST Researchers have caught a protein they previously implicated in a variety of cancer-promoting roles performing a vital function in cell division, survival and development of brain tumors. PKM2 controls mitosis, saving cancer cells from death and promoting brain tumor growth.

Angioplasty may not be better than drug therapy in stable disease Posted: 06 Dec 2013 01:29 PM PST For patients with stable coronary artery disease (CAD) who are not experiencing a heart attack and an abnormal stress test, treatment of their narrowed arteries by the common procedure of angioplasty may not provide additional benefits compared to drug therapy alone. This finding results from a survey of more than 4,000 patients with myocardial ischemia, or inadequate circulation, led by cardiologists.

Cigarette smoking after cancer diagnosis increases risk of death Posted: 06 Dec 2013 06:09 AM PST Men who continued to smoke after a cancer diagnosis had an increased risk of death compared with those who quit smoking after diagnosis, according to a study published.

Good relationships make women more satisfied with their weight Posted: 05 Dec 2013 07:00 PM PST Women who are in a satisfying relationship are more likely to be satisfied with their body weight.

Teachers' concern at the sexualization of children Posted: 05 Dec 2013 07:00 PM PST Research by a team of psychologists has found that of teachers report an increase in the frequency and intensity of sexually inappropriate behaviour by their pupils. Twenty-two teachers were interviewed, drawn from primary, secondary and special schools. The majority of respondents reported an increase in sexualized behavior in children, ranging from sexual language to coercive acts.

Feeling defeated, entrapped is linked to anxiety, depression Posted: 05 Dec 2013 07:00 PM PST Feeling defeated and entrapped is linked to anxiety and depression. This is the conclusion of research recently released by British researchers.

Safe haven for abuse victims life or death matter Posted: 05 Dec 2013 06:59 PM PST Based on in-depth interviews with survivors of intimate partner violence, this study confirms the critical nature of safe housing and identifies significant barriers to it.

Better diagnoses may help vets with anxiety get treatment Posted: 05 Dec 2013 01:58 PM PST Veterans who suffer from anxiety may not get appropriate treatment for want of a specific diagnosis, finds a new study.

Approaches to pain assessment in cancer clinical trials Posted: 05 Dec 2013 01:57 PM PST Researchers have developed guidelines to help drug developers include meaningful pain endpoints when designing cancer trials.

Study aims to reduce stress in high-risk, high-poverty schools Posted: 05 Dec 2013 01:57 PM PST Researchers will launch a pilot study to test the effects of an intervention targeted to reduce school-wide stress.

Fundamental differences found between human cancers, genetically engineered mouse models Posted: 05 Dec 2013 11:22 AM PST Researchers have taken a closer look at existing mouse models of cancer, specifically comparing them to human cancer samples. These genetically engineered mouse models (which usually either overexpress a cancer-causing gene--or "oncogene"--or carry a deletion for a "tumor suppressor" gene) have been extensively used to understand human cancer biology in studies of drug resistance, early detection, metastasis, and cancer prevention, as well as for the preclinical development of novel targeted therapeutics.

New IOM report assesses oversight of clinical gene transfer protocols Posted: 05 Dec 2013 11:22 AM PST In most cases, human gene transfer research is no longer novel or controversial enough to require additional review from the National Institutes of Health's Recombinant DNA Advisory Committee, known as RAC, says a new report by the Institute of Medicine.

When it comes to peer pressure, teens are not alone Posted: 05 Dec 2013 11:21 AM PST It is well known that teenagers take risks -- and when they do, they like to have company. Now, a new study has found that an inclination toward risky behavior in groups also holds true for another teen mammal -- namely, mice.

International study finds lower-dose IUDs safe, effective Posted: 05 Dec 2013 11:21 AM PST In a finding that could expand the use of one of the most effective forms of birth control, two intrauterine contraceptive systems that had lower doses of the contraceptive hormone, levonorgestrel, were found to be safe and effective in preventing pregnancies.

Sudden interest in math -- how teachers can motivate pupils Posted: 05 Dec 2013 11:19 AM PST In the eighth or ninth grade, many pupils lose interest in natural sciences and math. Researchers have shown that this does not have to be the case. They devised a professional development program where teachers learned to change the communication in class rooms. Breaking the mold for these subjects, these teachers encouraged open discussion and gave individual feedback. And -- again breaking the mold -- the youngsters showed rising levels of motivation.

Home-based exercise as rehabiltation Posted: 05 Dec 2013 11:19 AM PST Home-based high-intensity exercise for rehabilitation after cardiovascular disease can be effective, even if patients work out without expensive exercise monitoring machines, new research from the Norwegian researchers has shown.
