Brain

Researchers from the NUTRIMENTHE project have addressed this in a five-year study involving hundreds of European families with young children. Researchers looked at the effect of, B-vitamins, folic acid, breast milk versus formula milk, iron, iodine and omega-3 fatty acids, on the cognitive, emotional and behavioural development of children from before birth to age nine.

La Jolla, CA----In the past few years, as imaging tools and techniques have improved, scientists have been working tirelessly to build a detailed map of neural connections in the human brain---- with the ultimate hope of understanding how the mind works.

Dr. Jixiang Ren and team from the Affiliated Hospital to Changchun University of Chinese Medicine proposed a therapeutic principle for Poxue Huayu and Tianjing Busui (i.e., breaking blood stasis, replenishing essence). The researchers established cerebral hemorrhage rat models which were intragastrically administered 5, 10, 20 g/kg Poxue Huayu and Tianjing Busui Decoction, supplemented with Hirudo, raw rhubarb, raw Pollen Typhae, gadfly, Fructrs Trichosanthis, Radix Notoginseng, Rhizoma Acori Talarinowii, and glue of tortoise plastron, once a day, for 14 consecutive days.

Anti-bullying initiatives have become standard at schools across the country, but a new UT Arlington study finds that students attending those schools may be more likely to be a victim of bullying than children at schools without such programs.

The findings run counter to the common perception that bullying prevention programs can help protect kids from repeated harassment or physical and emotional attacks.

• While hangovers may be a source of humor, their effects can be debilitating, costly, and even dangerous.
• A new study of hangovers across the lifespan has found that the tendency to experience hangovers decreases as age increases.
• Study authors speculate that older adults who binge drink do so to a lesser intensity than younger adults.

• Previous research has found contradictory linkages among cognition, verbal skills, and later alcohol use.
• A new study has found that better verbal development during childhood predicts more frequent drinking and intoxication during adolescence and young adulthood.
• Study authors speculate this verbal/alcohol association may be partially due to peer associations.

The juvenile Issus - a plant-hopping insect found in gardens across Europe - has hind-leg joints with curved cog-like strips of opposing 'teeth' that intermesh, rotating like mechanical gears to synchronise the animal's legs when it launches into a jump.

The finding demonstrates that gear mechanisms previously thought to be solely man-made have an evolutionary precedent. Scientists say this is the "first observation of mechanical gearing in a biological structure".

JUPITER, FL – September 12, 2013 – Scientists from the Florida campus of The Scripps Research Institute (TSRI) have found a group of proteins essential to the formation of long-term memories.

The study, published online ahead of print on September 12, 2013 by the journal Cell Reports, focuses on a family of proteins called Wnts. These proteins send signals from the outside to the inside of a cell, inducing a cellular response crucial for many aspects of embryonic development, including stem cell differentiation, as well as for normal functioning of the adult brain.

WASHINGTON -- Rates of physical and sexual abuse of children have declined over the last 20 years, but for reasons not fully understood, says a new report from the Institute of Medicine. Yet, reports of psychological and emotional child abuse have risen in the same period, and data vary significantly as to whether child neglect is increasing, decreasing, or remaining constant. However, determining the incidence of child abuse and neglect presents a number of challenges, because cases could be underreported and definitions vary among entities that collect such information.

CINCINNATI – New research in mouse models suggests that treatment with antioxidants may help reduce behavioral issues linked to the genetic nervous system disorder Neurofibromatosis 1 (NF1) and an associated condition called Costello syndrome.

Scientists from Cincinnati Children's Hospital Medical Center report their findings Sept. 12 in Cell Reports. The authors show that defects in the NF1/Ras molecular pathway, which cause the disorders, trigger production of harmful oxidative nitric oxide molecules in the oligodendrocyte glial brain cells of mice.

Alzheimer's disease is thought to be caused by the buildup of abnormal, thread-like protein deposits in the brain, but little is known about the molecular structures of these so-called beta-amyloid fibrils. A study published by Cell Press September 12th in the journal Cell has revealed that distinct molecular structures of beta-amyloid fibrils may predominate in the brains of Alzheimer's patients with different clinical histories and degrees of brain damage.

PROVIDENCE, R.I. [Brown University] — Brown University researchers have traced a genetic deficiency implicated in autism in humans to specific molecular and cellular consequences that cause clear deficits in mice in how well neurons can grow the intricate branches that allow them to connect to brain circuits. The researchers also show in their study (online Sep. 12, 2013, in Neuron) that they could restore proper neuronal growth by compensating for the errant molecular mechanisms they identified.

PITTSBURGH—Analyses of Twitter feeds have been used to track flu epidemics, predict stock market changes and do political polling, but now that the National Football League season is underway, the natural question is: Can Twitter help beat the spread on NFL games?

The answer, say computer scientists at Carnegie Mellon University, is yes. Or, at least it can help a little bit at certain times during the season. They will report their findings Sept. 27 at the Machine Learning and Data Mining for Sports Analytics conference in Prague, Czech Republic.

If the violins were taken away from the musicians performing Beethoven's 9th symphony, the resulting composition would sound very different. If the violins were left on stage but the violinists were removed, the same mutant version of the symphony would be heard.

But what if it ended up sounding like "Hey Jude" instead?

Basic fibroblast growth factor exhibits a high affinity for heparin. Heparin combined with basic fibroblast growth factor significantly contributes to the differentiation of umbilical cord mesenchymal stem cells into motor neurons.

Xueyuan Liu and colleagues from Liaoning Medical University found that the third passage of umbilical cord mesenchymal stem cells induced with heparin and basic fibroblast growth factor exhibited neuronal morphology, and Hb9 expression and acetylcholine levels increased following induction with heparin combined with basic fibroblast growth factor.
