Acupuncture is more effective than oral antidepressants in improving depressive symptoms, and produces fewer side effects than tricyclic antidepressants. Despite the continued development of antidepressants and alternative/synergistic therapies, major depressive disorder has not been comprehensively recognized and treatment outcome is often insufficient. An epidemiological study addressing depression showed that poor recognition and treatment are largely linked to the lack of an accurate assessment tool and to patients' economic situation. Prof.

WASHINGTON – Military men who are targets of frightening and threatening sexual harassment may experience more distress and work performance problems than military women who face the same treatment, according to research published by the American Psychological Association.
The Chinese compound Kaixin Jieyu Fang can be used to treat vascular depression; however, the underlying mechanism remains unclear. Dr. Ying Zhang and co-workers from Guang'anmen Hospital, China Academy of Chinese Medical Sciences in China This study established a rat model of chronic cerebral ischemia-caused white matter damage by ligation of the bilateral common carotid arteries. Rats received daily intragastric administration of a suspension of Kaixin Jieyu Fang powder.
WASHINGTON (March 27, 2014) — Dramatic spikes in cases of Takotsubo cardiomyopathy, also called broken heart syndrome, were found in two states after major natural disasters, suggesting the stress of disasters as a likely trigger, according to research to be presented at the American College of Cardiology's 63rd Annual Scientific Session. Authors call for greater awareness among emergency department physicians and other first responders.
Developing treatments that slow, if not halt, the neuronal loss and cognitive decline of Alzheimer's disease (AD) has proven to be a challenge. Among the scientists who have taken on that challenge are researchers at the University of Florida's McKnight Brain Institute in Gainesville, using the fruit fly Drosophila melanogaster as a model.
The scientists are investigating passive immunotherapy, one of the most promising approaches to blocking the amyloid-β42 (Aβ42) peptide, the main component of the amyloid plaques that damage the brain cells of patients with AD.
Researchers at the University of California, San Diego School of Medicine and the Allen Institute for Brain Science have published a study that gives clear and direct new evidence that autism begins during pregnancy.
The study will be published in the March 27 online edition of the New England Journal of Medicine.
The architecture of the autistic brain is speckled with patches of abnormal neurons, according to research partially funded by the National Institute of Mental Health (NIMH), part of the National Institutes of Health. Published in the New England Journal of Medicine on March 27, 2014, this study suggests that brain irregularities in children with autism can be traced back to prenatal development.
Amyotrophic lateral sclerosis, also known as Lou Gehrig's disease, is marked by a cascade of cellular and inflammatory events that weakens and kills vital motor neurons in the brain and spinal cord. The process is complex, involving cells that ordinarily protect the neurons from harm. Now, a new study by scientists in The Research Institute at Nationwide Children's Hospital points to a potential culprit in this good-cell-gone-bad scenario, a key step toward the ultimate goal of developing a treatment.
Working with genetically engineered mice, Johns Hopkins neuroscientists report they have identified what they believe is the cause of the vast disintegration of a part of the brain called the corpus striatum in rodents and people with Huntington's disease: loss of the ability to make the amino acid cysteine. They also found that disease progression slowed in mice that were fed a diet rich in cysteine, which is found in foods such as wheat germ and whey protein.
Long-term brain damage caused by stroke could be reduced by saving cells called pericytes that control blood flow in capillaries, reports a new study led by scientists from UCL (University College London).
Until now, many scientists believed that blood flow within the brain was solely controlled by changes in the diameter of arterioles, blood vessels that branch out from arteries into smaller capillaries. The latest research reveals that the brain's blood supply is in fact chiefly controlled by the narrowing or widening of capillaries as pericytes tighten or loosen around them.
Support in developed countries for natural history—the study of the fundamental nature of organisms and how and where they live and interact with their environment—appears to be in steep decline. Yet natural history provides essential knowledge for fields as varied as human health, food security, conservation, land management, and recreation.
Decreased exposure to air pollution in utero is linked with improved childhood developmental and higher levels of brain-derived neurotrophic factor (BDNF), a key protein for brain development, according to a study of looking at the closure of coal-burning power plant in China led by researchers at the Columbia Center for Children's Environmental Health at the Mailman School of Public Health.
Organisms must be able to sense signals from the outside and translate these into biochemical cues in order to adequately respond to their environment. This capability is also required to process information that reaches the brain. Within the brain, stimulation of neurons activates genes that are required, for example for learning and memory. In collaboration with an international and interdisciplinary team the research group led by Prof.
Scientists at the RIKEN Center for Life Science Technologies have used PET imaging to visualize the distribution in the body of copper, which is deregulated in Menkes disease, a genetic disorder, using a mouse model. This study lays the groundwork for PET imaging studies on human Menkes disease patients to identify new therapy options.
Mesenchymal stem cell transplantation is a novel means of treating cerebral ischemia/reperfusion, and can promote angiogenesis and neurological functional recovery. Acupuncture at Conception and Governor vessels also has positive effects as a treatment for cerebral ischemia/reperfusion. Therefore, Prof.
