Endocrine disrupting flame retardant (FR) chemicals form a human health concern, that is investigated mostly from the perspective of adult- and early life exposure. No overview of studies on toddler exposure and health effects exist. However, toddlerhood is a critical developmental period and toddlers are at increased risk for exposure because of their age-specific behavior. This systematic review encompasses toddler FR exposure studies in three countries, associated health effects and potential environmental, demographic, or behavioral risk- or protective factors for toddler exposure...

The benefits of sleep on memory consolidation have been enhanced for declarative and motor sequence learning through replaying classically conditioned auditory stimuli during sleep, known as targeted memory reactivation (TMR). However, it is unknown if TMR can influence performance of a sensorimotor skill, in the absence of the cognitive requirements of sequence learning. Here, young adults performed a nondominant arm throwing task separated by a full night of sleep or a full day of wake, with half of all participants receiving TMR between sessions...

PURPOSE: To introduce a new realistic human skull phantom for the validation of synthetic CT images of cortical bone from ultra-short echo-time (UTE) sequences. METHODS AND MATERIALS: A human skull of an adult female was utilized as a realistic representation of skull cortical bone. The skull was stabilized in a special acrylic container and was filled with contrast agents that have T1 and T2 relaxation times similar to human brain. The phantom was MR scanned at 3T with UTE and T2 -weighted sequences, followed by CT...

Sirtuins are pleiotropic NAD+ dependent histone deacetylases involved in metabolism, DNA damage repair, inflammation and stress resistance. SIRT6, a member of the sirtuin family, regulates the process of normal aging and increases the lifespan of male mice over-expressing Sirt6 by 15%. Neurogenesis, the formation of new neurons within the hippocampus of adult mammals, involves several complex stages including stem cell proliferation, differentiation, migration and network integration. During aging, the number of newly generated neurons continuously declines, and this is correlated with a decline in neuronal plasticity and cognitive behavior...

Behçet's disease is a vasculitis that can cause inflammatory lesions in multiple organs or systems including the nervous system. Most cases worldwide have been reported along what is called the "Silk Route" from the Mediterranean region to Japan, so it is considered a rare disease in Latin American countries. The frequency of neurological involvement ranges from 5 to 13%. We present the case of a young adult woman with diagnostic criteria for Behçet's disease and manifestations of neurological disease, as well as a review of the literature...

Despite significant advances in basic research, the treatment of degenerative diseases of the nervous system remains one of the greatest challenges for translational medicine. The childhood onset motor neuron disorder spinal muscular atrophy (SMA) has been viewed as one of the more tractable targets for molecular therapy, due to a detailed understanding of the molecular genetic basis of the disease. In SMA, inactivating mutations in the SMN1 gene can be partially compensated for by limited expression of SMN protein from a variable number of copies of the SMN2 gene, which provides both a molecular explanation for phenotypic severity and a target for therapy...

OBJECTIVES: A growing population of adolescents/young adults with eosinophilic esophagitis (EoE) and eosinophilic gastroenteritis (EGE) will need to transition from pediatric to adult health providers. Measuring health care transition (HCT) readiness is critical, but no studies have evaluated this process in EoE/EGE. We determined the scope and predictors of HCT knowledge in patients and parents with EoE/EGE and measured HCT readiness in adolescents/young adults. METHODS: We conducted an online survey of patients 13 years or older and parents of patients with EoE/EGE who were diagnosed when 25 years or younger...

Fibrinogen (Fib) is a useful marker for predicting the severity of coronary artery disease (CAD) in adult population. However, whether Fib can be a predictor for the presence and severity of CAD in very young MI patients (≤35 years old) remains to be determined. A total of 418 males from 61,863 patients with MI who were under 35 years old were sequentially recruited in our study. The patients were divided into two main groups and three subgroups according to coronary angiograph and Gensini score (GS) system: no coronary artery stenosis (group A), the results of the coronary artery stenosis (group B); low GS, intermediate GS and high GS...

It has been suggested that an age-related positivity effect may only occur in the context of explicit information processing, but it is unclear whether this bias extends to the processing of rapid facial reactions. In addition, most studies that have looked for evidence of age-related implicit positivity have used attentional (as opposed to sensory) unawareness paradigms, or used broad-based indicators of attentional awareness that do not speak to the nature of the affective response. In the present study, younger and older adults were therefore asked to view non-facial images presented supraliminally (i...

Osteosarcoma is a primary malignancy of bone that affects children and adults. Here, we present the largest sequencing study of osteosarcoma to date, comprising 112 childhood and adult tumours encompassing all major histological subtypes. A key finding of our study is the identification of mutations in insulin-like growth factor (IGF) signalling genes in 8/112 (7%) of cases. We validate this observation using fluorescence in situ hybridization (FISH) in an additional 87 osteosarcomas, with IGF1 receptor (IGF1R) amplification observed in 14% of tumours...

BACKGROUND: Forkhead box P3 (Foxp3) is the most reliable marker for regulatory T cells, which play an important role in maintaining renal allograft tolerance. Recently, Foxp3 polymorphisms have been reported to be associated with graft outcome in kidney transplantation. We analyzed the association of Foxp3 polymorphisms with renal allograft outcome. METHODS: Foxp3 polymorphisms (rs3761548 A/C, rs2280883 C/T, rs5902434 del/ATT, and rs2232365 A/G) were tested by PCR with sequence-specific primers (PCR-SSP) in 231 adult kidney transplantation recipients from 1996-2004 at Seoul National University Hospital...

Recent technological innovations have increased the amount of tobacco products available to smokers. In particular, electronic cigarettes, sometimes call e-cigarettes, have received substantial attention as their sales have rapidly increased. Electronic cigarettes were invented in China and now have become prevalent worldwide. Electronic cigarettes can be considered fashionable and come in numerous flavors; accordingly, many young adults and students have begun to use e-cigarettes. However, like traditional tobacco products, e-cigarettes have negative influences on human health...

Although research shows that spouses influence each other's health behaviors and psychological well-being, we know little about whether these patterns extend to young people in nonmarital as well as marital relationships. We use the National Longitudinal Study of Adolescent to Adult Health to consider how a romantic partner's binge drinking and depression influence the respondent's binge drinking and depression within 1,111 young adult couples and explore whether these processes are moderated by gender. We find that partners' binge drinking is associated with increased odds of binge drinking for respondents, and partners' depression is associated with increased odds of depression for respondents...

Myotonic dystrophy, or Steinert's disease, is the most common form of muscular dystrophy that occurs in adults. This multisystemic form involves the skeletal muscles but affects also the eye, the endocrine system, the central nervous system, and the cardiac system. The weakness of the facial muscles causes a characteristic facial appearance frequently associated with malocclusions. Young people with myotonic dystrophy, who also have severe malocclusions, have bad oral functions such as chewing, breathing, and phonation...

The use of electronic cigarettes (e-cigs) is increasing rapidly, but their effects on lung toxicity are largely unknown. Smoking is a well-established cause of lung cancer and respiratory disease, in part through inflammation. It is plausible that e-cig use might affect similar inflammatory pathways. E-cigs are used by some smokers as an aid for quitting or smoking reduction, and by never smokers (e.g., adolescents and young adults). The relative effects for impacting disease risk may differ for these groups...

BACKGROUND: Electronic word-of-mouth on social network sites has been used successfully in marketing. In social marketing, electronic word-of-mouth about products as health behaviors has the potential to be more effective and reach more young adults than health education through traditional mass media. However, little is known about what motivates people to actively initiate electronic word-of-mouth about health behaviors on their personal pages or profiles on social network sites, thus potentially reaching all their contacts on those sites...
