Cells could be orientated in a controlled way on a micro-patterned surface based upon a delicate material technique, and the orientation could be semi-quantitatively described by some statistical parameters, as suggested by the group of DING from Fudan University, Shanghai, CHINA. The study is reported in Issue 18, Volume 54 (September 2009) of the Chinese Science Bulletin as one of the papers in a special issue about Biomedical Materials in this journal.

New findings reveal a large gap between US and UK researchers in terms of policy, attitudes, practices and experiences in relation to including ethnic minorities in asthma research. The study, published this week in the open access journal PLoS Medicine, shows that US researchers were more positive than their UK counterparts about the importance and logistics of including ethnic minorities in health research.
SEATTLE – For the first time, researchers at Fred Hutchinson Cancer Research Center have demonstrated that it is possible to successfully recruit and retain a large number of adolescent smokers from the general population into a smoking intervention study and, through personalized, proactive telephone counseling, significantly impact rates of six-month continuous quitting. These findings, by Arthur V. Peterson Jr., Ph.D., Kathleen A. Kealey and colleagues, are reported in a pair of papers in the Oct.
An outbreak of bloodstream infections appears to have been caused by the contamination of pre-filled heparin and saline syringes made by a single company, according to a report in the October 12 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. The subsequent investigation revealed that the company was not in compliance with safety regulations and identified challenges and areas for improvement in medication monitoring systems.
Critical illness among Canadian patients with 2009 influenza A(H1N1) occurred rapidly after hospital admission, often in young adults, and was associated with severely low levels of oxygen in the blood, multi-system organ failure, a need for prolonged mechanical ventilation, and frequent use of rescue therapies, according to a study to appear in the November 4 issue of JAMA. This study is being published early online to coincide with its presentation at a meeting of the European Society of Intensive Care Medicine.
Critical illness from 2009 influenza A(H1N1) in Mexico occurred among young patients, was associated with severe acute respiratory distress syndrome and shock, and had a fatality rate of about 40 percent, according to a study to appear in the November 4 issue of JAMA. This study is being published early online to coincide with its presentation at a meeting of the European Society of Intensive Care Medicine.
CHAPEL HILL – Children with functional abdominal pain who used audio recordings of guided imagery at home in addition to standard medical treatment were almost three times as likely to improve their pain problem, compared to children who received standard treatment alone.
And those benefits were maintained six months after treatment ended, a new study by University of North Carolina at Chapel Hill and Duke University Medical Center researchers has found.
The world will miss its agreed target to stem biodiversity loss by next year, according to experts convening in Cape Town for a landmark conference devoted to biodiversity science.
The goal was agreed at the 6th Conference of Parties to the UN Convention on Biological Diversity in April 2003. Some 123 world ministers committed to "achieve, by 2010, a significant reduction of the current rate of biodiversity loss at the local, national and regional levels, as a contribution to poverty alleviation and to the benefit of all life on Earth."
BOSTON – Although a wide spectrum of human papillomavirus is seen across the population of India, HPV-16 and HPV-18 are the most common types and a vaccination targeting these types could eliminate 75 percent of the cervical cancers in the region, according to data presented at the American Association for Cancer Research Frontiers in Basic Cancer Research Meeting.
Cervical cancer caused by HPV is the most common cancer among Indian women, with an estimated 132,000 new cases and 74,000 deaths annually.
Motor vehicle crashes are a leading cause of death among children despite the widespread availability of effective child passenger restraint systems (CPRSs) such as child safety seats. However, even when provided with free CPRSs and education about how to use them properly, many caregivers do not make them a part of their daily routine, according to the authors of a new study published in the Wisconsin Medical Journal (Vol. 108, No. 7).
CHICAGO (October 9, 2009) – According to a new study published in the October issue of the Journal of the American College of Surgeons, although breast-conserving surgery (BCS), commonly known as lumpectomy, is increasingly being used to treat older women with nonmetastatic invasive breast cancer, there are still significant socioeconomic and geographic disparities in the use of this type of therapy. For example, women in the Northeast and Pacific West are significantly more likely to receive BCS than those in the South and parts of the Midwest.
EAST LANSING, Mich. — Providing small classes for at least several consecutive grades starting in early elementary school gives students the best chance to succeed in later grades, according to groundbreaking new research from a Michigan State University scholar.
The research by Spyros Konstantopoulos, associate professor of education, is the first to examine the effects of class size over a sustained period and for all levels of students – from low- to high-achievers. The study appears in the American Journal of Education.
CAMBRIDGE, Mass --- Light readily bounces off obstacles in its path. Some of these reflections are captured by our eyes, thus participating in the visual perception of the objects around us. In contrast to this usual behavior of light, MIT researchers have implemented for the first time a one-way structure in which microwave light flows losslessly around obstacles or defects. This concept, when used in lightwave circuits, might one day reduce their internal connections to simple one-way conduits with much improved capacity and efficiency.
A new article recently published in the Journal for Specialists in Pediatric Nursing explored vaccination history, vaccine safety monitoring systems in the U.S., and the two most publicized theoretical vaccine-related exposures associated with autism – the vaccine preservative thimerosal and the measles, mumps, and rubella (MMR) vaccine. A review of published research shows that there is not convincing scientific evidence supporting a relationship between vaccines and autism. The article is part of a special issue, which includes five articles focusing on the topic of autism.
Because it will be difficult to prevent cyber attacks on critical civilian and military computer networks by threatening to punish attackers, the United States must focus its efforts on defending these networks from cyber attack, according to a new RAND Corporation study.
The study finds that the United States and other nations that rely on externally accessible computer networks -- such as ones used for electric power, telephone service, banking, and military command and control -- as a foundation for their military and economic power are subject to cyber attack.
