We systematically investigate the long-neglected low-temperature fusing behavior of silver micro/nano-dendrites and demonstrate the feasibility of employing this intriguing property for the printed electronics application, i.e. printed fuse-link. Fuse-link has experienced insignificant changes since they were invented in 1890's. By introducing the silver micro/nano-dendrites based electrically conductive composites (ECCs) as the printed fusible element, coupled with the state-of-the-art printed electronics technology, key performance characteristics of a fuse-link are dramatically improved as compared with the commercially-available counterparts, including expedient fabrication process, lower-available rated current (40% of the minimum value of Littelfuse 467 series fuses), shorter response time (only 3...

Although chronic inflammation and immune disorders are of great importance to the pathogenesis of both dementia and cancer, the pathophysiological mechanisms are not clearly understood. In recent years, growing epidemiological evidence and meta-analysis data suggest an inverse association between Alzheimer's disease (AD), which is the most common form of dementia, and cancer. It has been revealed that some common genes and biological processes play opposite roles in AD and cancer; however, the biological immune mechanism for the inverse association is not clearly defined...

Worldwide, virus infections are responsible for many diseases in terms of morbidity and mortality. Vaccinations and therapies are only available for relatively few virus infections and not always where they are needed. However, knowledge of transmission routes can prevent virus infection. In the context of this study, we measured the effects of a secondary school education module, named Viruskenner, on knowledge, attitude, and risk behavior as these relate to virus infections. A nonrandomized intervention study was conducted between April and August 2015 to assess the effect of this 2-month education module on knowledge, attitude, and behavior of 684 secondary school students in the Netherlands, Suriname, and Indonesia...

Over the past few decades, (poly)peptide block copolymers have been widely employed in generating well-defined nanostructures as vehicles for targeted drug delivery applications. We previously reported the assembly of thermoresponsive nanovesicles from an elastin-b-collagen like peptide (ELP-CLP). The nanoparticles were observed to dissociate at elevated temperatures, despite the LCST-like behavior of the tethered ELP domain, which is suggested to be triggered by the unfolding of the CLP domain. Here, the potential of using the nanoparticles as drug delivery vehicles for targeting collagen-containing matrices is evaluated...

Two-dimensional (2D) layered hybrid perovskites have shown great potentials in optoelectronics. However, although great efforts have been made, 2D hybrid perovskite ferroelectrics remain rare. Here, we constructed the first ferroelectric with 2D multilayered perovskite framework, (C4H9NH3)2(CH3NH3)2Pb3Br10 (1), by tailored alloying mixed-organic-cations into the prototype of CH3NH3PbBr3. For the first time, concrete ferroelectricity was created by molecular reorientation and synergic ordering of organic cations, which is unprecedented for the known 2D hybrid perovskites...

Fear of progression (FoP) is an appropriate, rational response to the real threat of cancer and its treatments. However, patients experiencing elevated, dysfunctional levels of FoP often feel severely distressed and are in need of treatment. We previously conducted a (partly-)randomized controlled study with cancer patients undergoing in-patient rehabilitation and showed that a brief, four-session cognitive-behavioral group therapy significantly reduced dysfunctional FoP. In this report, we describe the adaption of the cognitive-behavioral group therapy program for use with cancer out-patients...

This study is the first to analyze public response to a drug take-back program, the American Medicine Chest Challenge, in a single state over a period of 3 years (2010-2012). The study utilized a three-wave repeated cross-sectional design and an annual phone survey conducted with a representative sample of adults ( N = 906 in 2010, N = 907 in 2011, and N = 906 in 2012), which assessed exposure to the campaign, drug disposal behaviors, possible mediators of campaign effects (risk appraisal, personal agency, normative influence, and interpersonal talk), and potential confounders...

Background and aims Internet addiction (IA) was recently defined as a disorder tagging both the impulse control and the reward systems. Specifically, inhibitory deficits and reward bias were considered highly relevant in IA. This research aims to examine the electrophysiological correlates and autonomic activity [skin conductance response (SCR) and heart rate] in two groups of young subjects (N = 25), with high or low IA profile [tested by the Internet Addiction Test (IAT)], with specific reference to gambling behavior...

Biodiesel for combustible engine is available as mixture of fossil diesel and fatty esters obtained by transesterification of vegetable oils. The use of biodiesel reduces the amount of SOx, mainly. However, it was already observed that biodiesel has a different behavior in environment in cases of accidental spill and groundwater contamination. It was noticed that the biodegradation of hydrocarbons (cyclic and aliphatic) in the presence of biodiesel are speeded, although the mechanism is still unclear. Considering the chemical structure of fatty esters, it was investigated the formation of aggregates in water solution by fatty esters present in commercial biodiesel...

BACKGROUND: Posttraumatic Stress Disorder (PTSD) related to childhood sexual abuse (CSA) is often associated with a wide range of trauma-related aversive emotions such as fear, disgust, sadness, shame, guilt, and anger. Intense experience of aversive emotions in particular has been linked to higher psychopathology in trauma survivors. Most established psychosocial treatments aim to reduce avoidance of trauma-related memories and associated emotions. Interventions based on Dialectical Behavior Therapy (DBT) also foster radical acceptance of the traumatic event...

OBJECTIVE: The global resurgence of dengue has been attributed to rapid population growth, urban expansion, increased air travel, globalization, and climate change. Dengue is now endemic in Puerto Rico. Puerto Rico is at risk for Zika, another emerging arbovirus. The interrelationship between climatic, ecological, social, and cultural factors that affect dengue and other arboviruses' transmission is understudied. DESIGN: The objective of this systematic review is to examine the interrelationship between climatic, ecological, social, and cultural factors on dengue transmission in Puerto Rico and to draw lessons for Zika response...

The two-process model of sleep-wake regulation posits that sleep-wake-dependent homeostatic processes interact with the circadian timing system to affect human behavior. The circadian timing system is fundamental to maintaining stable cognitive performance, as it counteracts growing homeostatic sleep pressure during daytime. Using magnetic resonance imaging, we explored brain responses underlying working memory performance during the time of maximal circadian wake-promotion under varying sleep pressure conditions...

Adaptive behavior requires context-sensitive configuration of task-sets that specify time-varying stimulus-response mappings. Intriguingly, response time costs associated with changing task-sets and motor responses are known to be strongly interactive: switch costs at the task-level are small in the presence of a response-switch but large when accompanied by a response-repetition, and vice versa for response-switch costs. The reasons behind this well-known inter-dependence between task- and response-level control processes are currently not well understood...

Accurate and adaptive encoding of complex, dynamic visual information is critical for the survival of many animals. Studies across a range of taxa have investigated behavioral and neuronal responses to objects that represent a threat, such as a looming object approaching along a direct collision course. By investigating neural mechanisms of avoidance behaviors through recording multineuronal activity, it is possible to better understand how complex visual information is represented in circuits that ultimately drive behaviors...

Parkinson disease (PD) is a degenerative disorder characterized by several motor symptoms including shaking, rigidity, slow movement and difficult walking, which has been associated to the death of nigro-striatal dopaminergic neurons. >90% of PD patients also present olfactory dysfunction. Although the molecular mechanisms responsible for this disease are not clear, hereditary PD is linked to mutations in specific genes, including the PTEN-induced putative kinase 1 (PINK1). In this work we provide for the first time a thorough temporal description of the behavioral effects induced by a mutation in the PINK1 gene in adult Drosophila, a previously described animal model for PD...

There is not a single and perfect instinctive behavior to react to threatening situations. However, the study of particular features of these situations suggests the existence of prototypical emotional reactions and associated defensive behaviors. Since all living beings are subjected to common evolutionary pressures, such as predation and conspecific competition, it is plausible that there is conservation of some basic defensive responses in their behavioral repertoire. The choice for approaching or withdrawing from a given situation depends, among others things, on environmental features, including the threat intensity and the distance from the source of the threat...

No pharmacotherapies are approved for the treatment of cocaine use disorders (CUD). Behavioral treatments for CUD are efficacious for some individuals, but recovery rates from CUD remain low. Cognitive impairments in CUD have been linked with poorer clinical outcomes. Cognitive enhancing pharmacotherapies have been proposed as promising treatments for CUD. Atomoxetine, a norepinephrine transporter inhibitor, shows potential as a treatment for CUD based on its efficacy as a cognitive enhancer in other clinical populations and impact on addictive processes in preclinical and human laboratory studies...

Individual differences in dimensions of impulsivity personality including disinhibition and sensation seeking modulate approach responses to reinforcing stimuli, such as drugs and money. The current study examined the effects of monetary incentive on both behavioral performance and electrophysiological activity among individuals varying in disinhibition and sensation seeking. The monetary incentive delay (MID) task was completed under electroencephalogram (EEG) recording. Behavioral data showed that higher disinhibition and sensation-seeking were associated with lower performance accuracy...

BACKGROUND: Physical and mental health is dependent on the environment, and feeding is a prime example of this environmental exchange. While the hypothalamus controls both feeding behavior and the stress response, the integration of the neural control centers and the peripheral gut allows for disruption in the gastrointestinal systems and dysfunctional communication to the brain. OBJECTIVE: The purpose of this review is to familiarize clinicians with the physiology controlling feeding behavior and its implications for psychiatric conditions, such as anorexia nervosa and depression...

At present, it is not clear whether α1-adrenoceptors in the prelimbic cortex (PrL) are involved in Parkinson's disease-related depression. Here we examined effects of PrL α1-adrenoceptors on depressive-like behaviors in rats with unilateral 6-hydroxydopamine lesions of the medial forebrain bundle. The lesion induced depressive-like responses as measured by the sucrose preference and forced swim tests compared to sham-operated rats. Intra-PrL injection of α1-adrenoceptor agonist phenylephrine induced or increased the expression of depressive-like behaviors in sham-operated and the lesioned rats...
