Synthetic Silicate Used To Stimulate Stem Cells Into Bone Cells
Date: May-16-2013In new research published online in Advanced Materials, researchers from Brigham and Women's Hospital (BWH) are the first to report that synthetic silicate nanoplatelets (also known as layered clay) can induce stem cells to become bone cells without the need of additional bone-inducing factors. Synthetic silicates are made up of simple or complex salts of silicic acids, and have been used extensively for various commercial and industrial applications, such as food additives, glass and ceramic filler materials, and anti-caking agents...
Better Understanding Of Cells' Development Has Implications In Study Of Inflammatory Diseases
Date: May-16-2013Labs around the world, and a core group at Penn, have been studying recently described populations of immune cells called innate lymphoid cells (ILCs). Some researchers liken them to foot soldiers that protect boundary tissues such as the skin, the lining of the lung, and the lining of the gut from microbial onslaught. They also have shown they play a role in inflammatory disease, when the body's immune system is too active. In animal studies, group-2 innate lymphoid cells (ILC2s) confer immunity during a parasitic infection in mice and are also involved in allergic airway inflammation...
Breastfeeding May Help Prevent ADHD In Children
Date: May-16-2013Breastfeeding may help prevent children from developing ADHD (attention-deficit/hyperactivity disorder) later in life, according to a new study. The research was conducted by a team of Israeli researchers and published in Breastfeeding Medicine, the official journal of the Academy of Breastfeeding Medicine. The scientists, led by Aviva Mimouni-Bloch, MD, of the Tel-Aviv University (TAU) Sackler Faculty of Medicine, wanted to determine whether the development of ADHD might be linked to a shorter duration of breastfeeding...
Listening To Upbeat Music Helps Us To Improve Our Mood
Date: May-16-2013The song, "Get Happy," famously performed by Judy Garland, has encouraged people to improve their mood for decades. Recent research at the University of Missouri discovered that an individual can indeed successfully try to be happier, especially when cheery music aids the process. This research points to ways that people can actively improve their moods and corroborates earlier MU research...
Researchers Find Male Testosterone Levels Increase When Victorious In Competition Against Rivals, But Not Friends
Date: May-16-2013Sporting events can bring a community together, such as when the Louisville Cardinals won the NCAA championship and University of Louisville campus was filled with camaraderie. They also can fuel bitter rivalries, such as the long-standing animosity between the St. Louis Cardinals and the Chicago Cubs. A University of Missouri study has found that testosterone levels during group competition are modulated depending on the relationships among the competitors and may be related to the formation of alliances in warfare...
New Algorithm Cluster To Data Mine Health Records Published By NJIT Computer Scientist
Date: May-16-2013The time may be fast approaching for researchers to take better advantage of the vast amount of valuable patient information available from U.S. electronic health records. Lian Duan, an NJIT computer scientist with an expertise in data mining, has done just that with the recent publication of "Adverse Drug Effect Detection," IEEE Journal of Biomedical and Health Informatics (March, 2013)...
Half Of All Adult Female Deaths In Rural Bangladesh Due To Non-Communicable Diseases
Date: May-16-2013While global attention has for decades been focused on reducing maternal mortality, population-based data on other causes of death among women of reproductive age has been virtually non-existent. A study conducted by researchers at the Johns Hopkins Bloomberg School of Public Health found that non-communicable diseases accounted for 48 percent of 1,107 investigated female deaths in rural Bangladesh between 2002 and 2007. The findings lend urgency to review global health priorities to address neglected and potentially fatal non-communicable diseases affecting rural women in South Asia...
Critical Need For Intervention For Brazil's Crack Users
Date: May-16-2013A Brazilian investigative team, collaborating with a Simon Fraser University researcher, is citing an urgent need for targeted interventions among young crack users in cities throughout Brazil, identified as the world's biggest crack market, and further research to better address the problem. SFU health sciences professor Benedikt Fischer and his Brazilian collaborators carried out a study of 160 young adult crack users in Rio de Janeiro and Salvador. Its findings paint a somber picture of socially disenfranchised drug users with extensive health problems and involvement in crime...
Study Findings May Offer New Way To Kill Cancer Cells By Forcing Them Into An Alternative Programmed Death Pathway
Date: May-16-2013When cells suffer too much DNA damage, they are usually forced to undergo programmed cell death, or apoptosis. However, cancer cells often ignore these signals, flourishing even after chemotherapy drugs have ravaged their DNA. A new finding from MIT researchers may offer a way to overcome that resistance: The team has identified a key protein involved in an alternative death pathway known as programmed necrosis. Drugs that mimic the effects of this protein could push cancer cells that are resistant to apoptosis into necrosis instead...
Preterm Infants Benefit From Massage Therapy
Date: May-16-2013It seems that even for the smallest of people, a gentle massage may be beneficial. Newborn intensive care units (NICUs) are stressful environments for preterm infants; mechanical ventilation, medical procedures, caregiving activities and maternal separation create these stressful conditions. Born under-developed, preemies have an immature autonomic nervous system (ANS), which controls stress response and recovery. For a preemie, even a diaper change is stressful and the immature ANS over reacts to these stressors...
