Radioresistance is one of the undesirable impediments in hypoxia tumor, which sharply diminishes therapeutic effectiveness of radiotherapy and eventually results in the failure of their treatments. An attractive strategy for attenuating radioresistance is developing an ideal radiosensitization system with admirable radiosensitization capacity to attenuate tumor hypoxia and reinforce radiotherapy response in hypoxia tumor. Therefore, we describe the development of Gd-containing polyoxometalates-conjugated chitosan (GdW10@CS nanosphere) as a radiosensitization system for simultanous extrinsic and intrinsic radiosensitization, by generating overabundance cytotoxic reactive oxygen species (ROS) using high energy X-ray stimulation and mediating the hypoxia-inducible factor-1a (HIF-1a) siRNA to down-regulate HIF-1α expression and suppress the broken double-stranded DNA self-healing...

Reduced olfactory function is associated with altered trait disgust in men. This study sought to determine whether hyposmic women show similar changes in disgust responsiveness. We compared patients with hyposmia (25 men, 23 women) and 50 normosmic individuals (25 men, 25 women) with regard to their tendency to experience disgust across different disgust domains (disgust proneness), their self-disgust and their tendency to perceive their own disgust feelings as difficult to control and embarrassing (disgust sensitivity)...

Among children diagnosed with developmental delays, difficulties in self-regulation are prominent and have been linked to school readiness problems. The current study sought to examine the impact of the Kids in Transition to School (KITS) school readiness intervention program on self-regulation, with a specific focus on response monitoring skills, among children with developmental delays. Children (n = 20 in the KITS group and n = 21 in a services as usual group) were administered a flanker task during which event-related potential data were collected to examine group differences in response monitoring...

D Joseph Sexton, Rochelle C Glover, Joyce E Loper, Martin Schuster
Many microorganisms compete for extracellular iron using strain-specific chelators known as siderophores. The ferric-siderophore complex limits local access to iron because import requires a suitable cognate receptor. Interestingly, many species carry receptors that enable "cross-feeding" on heterologous siderophores made by neighboring organisms, although little is known about how this ubiquitous behavior is regulated. Here, we investigated the soil bacterium Pseudomonas protegens Pf-5, a strain remarkable for its ability to use dozens of heterologous siderophores...

REVIEW
Ivy A W Ho, Winston S N Shim
Glioblastoma is the most aggressive cancer of the brain. The dismal prognosis is largely attributed to the heterogeneous nature of the tumor, which in addition to intrinsic molecular and genetic changes is also influenced by the microenvironmental niche in which the glioma cells reside. The cancer stem cells (CSCs) hypothesis suggests that all cancers arise from CSCs that possess the ability to self-renew and initiate tumor formation. CSCs reside in specialized niches where interaction with the microenvironment regulates their stem cell behavior...

Herein, we designed an upper critical solution temperature (UCST)-type self-oscillating polymer that exhibited rhythmic soluble-insoluble changes induced by Belousov-Zhabotinsky (BZ) reaction. The target polymers were prepared by conjugating Ru(bpy)3, a catalyst for the BZ reaction, to ureido-containing poly(allylamine-co-allylurea) (PAU) copolymers. The Ru(bpy)3-conjugated PAUs exhibited UCST-type phase transition behavior, and the solubility of the polymer changed in response to the alternation in the valency of Ru(bpy)3...

Executive functions are important higher-order cognitive skills for goal-directed thought and action. These capacities contribute to successful school achievement and lifelong wellbeing. The importance of executive functions to children's education begins in early childhood and continues throughout development. This study explores contributions of child and family factors in early childhood to the development of executive function in adolescence. Analyses draw on data from the nationally representative study, Growing up in Australia: The Longitudinal Study of Australian Children...

BACKGROUND: Despite a growing body of scientific literature exploring the nature of meditation there is limited information on the characteristics of individuals who use it. This is particularly true of comparative studies examining prevalence and predictors of use of various forms of meditation. METHODS: A secondary analysis was conducted using data from the 2012 National Health Interview Survey (n = 34,525). Three popular forms of meditation were compared-mantra, mindfulness, and spiritual-to determine lifetime and 12-month use related to key sociodemographic, health behavior, health status, and healthcare access variables...

Research has implicated motivation and goal regulation in susceptibility to mood disorders. We studied for the first time key facets of motivation and goal regulation concurrently in relation to affective symptoms. The cross-national sample comprised 510 university students from the United States (n = 279) and United Kingdom (n = 231). Participants completed self-report measures of motivation, conditional goal setting, urgency, depression, anxiety, and mania risk. Structural Equation Modeling results found that behavioral activation system scores correlated negatively with depression and positively with mania risk, but were unrelated to anxiety...

Functional groups of materials are known to affect cell behaviors, yet the corresponding effect on stem cell differentiation are always coupled with that of cell spreading, it is thus unclear whether or not the chemical groups influence cell differentiation directly or via cell spreading indirectly. Herein we used a unique surface patterning technique to decouple the corresponding effects. Mesenchymal stem cells (MSCs) derived from bone marrow were seeded on surfaces coated with alkylthiols with one of 4 functional end groups (-CH3, -OH, -COOH and -NH2) and underwent 9-day chondrogenic induction...

Families of preschoolers participated in two dyadic home visits, once with mother (56 dyads) and once with father (59 dyads). Each member of the dyad provided three cortisol samples and participated in several interaction tasks that were behaviorally coded. Approximately half of the children had been diagnosed with autism spectrum disorders (ASD), whereas half were typically developing (TD). In a multilevel model, father's cortisol level at each timepoint predicted child cortisol. Father-child linkage was stronger in dyads that showed less reciprocity, in which fathers showed less sensitivity, and in which children showed less self-regulation and more withdrawal...

Noncompliance or non-adherence to randomized treatment is a common challenge when interpreting data from randomized clinical trials. The effect of an intervention if all participants were forced to comply with the assigned treatment (i.e., the causal effect) is often of primary scientific interest. For example, in trials of very low nicotine content (VLNC) cigarettes, policymakers are interested in their effect on smoking behavior if their use were to be compelled by regulation. A variety of statistical methods to estimate the causal effect of an intervention have been proposed, but these methods, including inverse probability of compliance weighted (IPCW) estimators, assume that participants' compliance statuses are reported without error...

BACKGROUND: Despite recent research establishing high rates of comorbidity between hoarding disorder and alcohol use disorders (AUD), no studies have systemically examined the associations between symptoms of hoarding and alcohol use. Moreover, no studies have explored potential mechanisms that may help to explain these relations. OBJECTIVES: Thus, the current study was designed to examine the associations between hoarding and AUD symptoms, as well as the mediating role of emotion dysregulation...

In this paper, we analyze the needs of individuals with Autism Spectrum Disorders (ASD) to have a pervasive, feasible and non-stigmatizing form of assistance in their emotional self-regulation, in order to ease certain behavioral issues that undermine their mental health throughout their life. We argue the potential of recent widespread wearables, and more specifically smartwatches, to achieve this goal. Then, a smartwatch system that implements a wide range of self-regulation strategies and infers outburst patterns from physiological signals and movement is presented, along with an authoring tool for smartphones that is to be used by caregivers or family members to create and edit these strategies, in an adaptive way...

It is still a challenging task to facilely grow microscale arrays on arbitrary substrates at low temperature conditions in solutions. Here, we have successfully formed ZnO microrod arrays on various substrates, including glass, gold coated glass, silicon wafer, and Teflon, by a single-step wet-chemical synthesis approach. We employ ammonia as the multifunctional reactant to modify the surface properties of the substrates and to regulate the pH of the reaction environment. Compared to other methods, no preloaded additives or seeds are required...

Self-regulation processes and violent contexts play an important role in predicting adolescents' aggressive behavior; less clear is how all three constructs are linked to each other over time. The present study examined the longitudinal relations among adolescents' self-reported effortful control (EC), exposure to community violence, both as a witness and as a victim, and aggressive behavior. Participants were 768 Italian adolescents (358 males) living in a high-risk context, with a mean age at T1 of 11 years in the younger cohort and 14 years in the older cohort...

Alcohol consumption may lead to deficits in the executive functions that govern self-regulation. These deficits could lead to risk-taking behaviors; therefore, it is important to determine the magnitude of these deficits on executive functioning. The purpose of this experiment was to investigate the acute effects of alcohol on three of the executive functions that are hypothesized to affect self-regulation, which are inhibition, set shifting, and working memory, using a mixed-methods study design. The participants were 75 moderate or heavy drinkers between the ages of 21 and 35 who were randomized into one of three beverage conditions (control, placebo, or 0...
