Helping Women From War-Torn Countries Cope With Sexual Violence
Date: Jun-07-2013In conflict-ridden countries around the world, rape and other forms of sexual violence are being used as weapons of war. In these settings, treatment services for victims are limited. A trial led by researchers at the Johns Hopkins Bloomberg School of Public Health examined an evidence-based group psychotherapy treatment for sexual violence survivors in the Democratic Republic of the Congo (DRC). According to the study, this group therapy achieved more dramatic results in reducing symptoms of post-traumatic stress disorder (PTSD), depression and anxiety compared to individual support services...
New Population Of Pluripotent Stem Cells Isolated From Fat Removed During Liposuction
Date: Jun-07-2013Researchers from the UCLA Department of Obstetrics and Gynecology have isolated a new population of primitive, stress-resistant human pluripotent stem cells easily derived from fat tissue that are able to differentiate into virtually every cell type in the human body without genetic modification. The cells, called Multi-lineage Stress-Enduring (Muse-AT) stem cells from fat, or adipose, tissue, were discovered by "scientific accident" when a piece of equipment failed in the lab, killing all the stem cells in the experiment except for the Muse-AT cells...
Combined Ketogenic Diet And Hyperbaric Oxygen Therapy Proves Effective Against Metastatic Cancer
Date: Jun-07-2013A combination of nontoxic dietary and hyperbaric oxygen therapies effectively increased survival time in a mouse model of aggressive metastatic cancer, a research team from the Hyperbaric Biomedical Research Laboratory at the University of South Florida has found. The study, "The Ketogenic Diet and Hyperbaric Oxygen Therapy Prolong Survival in Mice with Systemic Metastatic Cancer," was published online in PLOS ONE...
Cheese And Dairy Products May Prevent Cavities
Date: Jun-07-2013Consuming dairy products is vital to maintaining good overall health, and it's especially important to bone health. But there has been little research about how dairy products affect oral health in particular. However, according to a new study published in the May/June 2013 issue of General Dentistry, the peer-reviewed clinical journal of the Academy of General Dentistry (AGD), consuming cheese and other dairy products may help protect teeth against cavities...
Meditation Activates Anterior Cingulate Cortex, Eases Anxiety
Date: Jun-07-2013Scientists, like Buddhist monks and Zen masters, have known for years that meditation can reduce anxiety, but not how. Scientists at Wake Forest Baptist Medical Center, however, have succeeded in identifying the brain functions involved. "Although we've known that meditation can reduce anxiety, we hadn't identified the specific brain mechanisms involved in relieving anxiety in healthy individuals," said Fadel Zeidan, Ph.D., postdoctoral research fellow in neurobiology and anatomy at Wake Forest Baptist and lead author of the study...
New Plug-In Optical Sensor For Smartphones Could Diagnosis Kaposi's Sarcoma In The Field
Date: Jun-07-2013As antiretroviral drugs that treat HIV have become more commonplace, the incidence of Kaposi's sarcoma, a type of cancer linked to AIDS, has decreased in the United States. The disease, however, remains prevalent in sub-Saharan Africa, where poor access to medical care and lab tests only compound the problem. Now, Cornell University engineers have created a new smartphone-based system, consisting of a plug-in optical accessory and disposable microfluidic chips, for in-the-field detection of the herpes virus that causes Kaposi's...
Neuroscientists Examine Neural Synchronization Patterns During Addiction
Date: Jun-07-2013A cross-disciplinary collaboration of researchers in the School of Science at Indiana University-Purdue University Indianapolis (IUPUI) explores the neural synchrony between circuits in the brain and their behavior under simulated drug addiction. The two-year study could have broad implications for treating addiction and understanding brain function in conditions such as Parkinson's disease...
Learning By Our Mistakes
Date: Jun-07-2013If people are unable to perceive their own errors as they complete a routine, simple task, their skill will decline over time, Johns Hopkins researchers have found - but not for the reasons scientists assumed. The researchers report that the human brain does not passively forget our good techniques, but chooses to put aside what it has learned. The term "motor memories" may conjure images of childhood road trips, but in fact it refers to the reason why we're able to smoothly perform everyday physical tasks...
Half Of Patients With PTSD Also Suffer From Depression
Date: Jun-07-2013About one of every two people diagnosed with posttraumatic stress disorder (PTSD) also suffer symptoms of depression, according to new research by Case Western Reserve University's Department of Psychological Sciences. The analysis also concludes that both genders diagnosed with PTSD equally suffer from depression. Since women tend to report more symptoms of depression than men, this contradicts a general belief that women are more inclined to struggle with both...
Obesity And Neighborhood Features
Date: Jun-07-2013Living in a neighborhood that supports a healthy lifestyle can make a measurable difference in preventing obesity, according to a longitudinal study recently published in the journal Obesity. The five-year study found that significantly fewer people became obese when living in neighborhoods with healthier food environments, compared to those who had fewer healthy food options within a mile of their homes...
