Strategies adopted by individuals in a social network significantly impact the network, and they strongly affect relationships between individuals in the network. Links between individuals also heavily influence their levels of cooperation. Taking into account the evolution of each individual's connection, we explore how sensitivity and visibility affect the prisoner's dilemma game. The so-called 'sensitivity' and 'visibility' respectively present one's self-protection consciousness and the ability of gaining information...

Drosophila suzukii Matsumura (Diptera: Drosophilidae) is an invasive, polyphagous fruit fly that attacks soft-skinned fruits. Originally from Asia, D. suzukii has successfully invaded the United States and the European and South American countries. At present, calendar-based insecticide applications are used to combat D. suzukii. Here, we evaluate a behaviorally based attract-and-kill management technique using attracticidal spheres to reduce D. suzukii infestations in raspberries. In laboratory bioassays aimed at identifying effective toxicants, attracticidal spheres containing dinotefuran at 1...

OBJECTIVE: Despite the prevalence of interpersonal violence (IPV), scientific understanding of the risk and protective factors for unidirectional and bidirectional IPV, and especially the role of sociocultural variables in these behaviors, is limited. This study investigates the association between ethnic-identity search, ethnic-identity affirmation, perceived discrimination, and unidirectional (victimization only, perpetration only) and bidirectional (reciprocal violence) IPV behaviors among foreign-born and U...

The turtle carapace, the top dorsal part of the shell, is a remarkable multi-scale dermal armor that has evolved to withstand various types of high-stress events encountered in nature. This keratin-covered boney exoskeleton exhibits a number of structural motifs, including alternating rigid and flexible components, layering and functionally graded elements, designed to protect the reptile during predatory attacks, and smashing events. Here we review the multi-scale structural hierarchy of the turtle carapace and its corresponding mechanical properties...

BACKGROUND: College-related alcohol beliefs, or beliefs that drinking alcohol is central to the college experience, have been shown to robustly predict alcohol-related outcomes among college students. Given the strength of these associations, it is imperative to understand more proximal factors (i.e., closer in a causal chain leading to alcohol-related outcomes) that can explain these associations. OBJECTIVES: The current research examined alcohol protective behavioral strategies (PBS) as a potential mediator of the association between college-related alcohol beliefs and alcohol outcomes among college student drinkers...

Stem cells from human exfoliated deciduous teeth (SHED) transplants have been investigated as a possible treatment strategy for spinal cord injuries (SCI) due to their potential for promoting functional recovery. The aim of present study was to investigate the effects of SHED on neuronal death after an experimental model of SCI. METHODS: Wistar rats were spinalized using NYU impactor®. Animals were randomly distributed into 4 groups: Control (Naive) or Surgical control, Sham (laminectomy with no SCI); SCI (laminectomy followed by SCI, treated with vehicle); SHED (SCI treated with intraspinal transplantation of 3×10(5) SHED, 1 h after SCI)...

Inclusion of compatible living donor and recipient pairs (CPs) in kidney paired donation (KPD) programs could increase living donor transplantation. We introduce the concept of a reciprocity based strategy in which the recipient of a CP that participates in KPD receives priority for a repeat deceased donor transplant in the event their primary living donor KPD transplant fails, and review the practical and ethical considerations of this strategy. The strategy limits prioritization to CPs already committed to living donation, minimizing the risk of unduly influencing donor behavior...

OBJECTIVE: Given the high prevalence of marijuana use among college students, it is imperative to determine the factors that may reduce risk of problematic marijuana use and/or the development of cannabis use disorder. We examined marijuana protective behavioral strategies (PBS) as a proximal predictor of marijuana-related outcomes and a mediator of the associations between other known risk/protective factors and marijuana-related outcomes. METHOD: Using data from a sample of 2,129 past-month marijuana users, collected from 11 universities in the United States, we examined marijuana PBS use as a mediator of the effects of sex, age at first use, impulsivity-like traits, and marijuana use motives on marijuana use frequency and marijuana related consequences...

Mesenchymal stem cells (MSC) are promising candidates for adult cell therapies in regenerative medicine. To fully exert their potential, efficient homing and migration towards lesion sites plays an important role. Local transplantation deposits MSC in spatial proximity to the lesion, but often requires invasive procedures. Systemic administration routes are favored, but require the targeted extravasation of the circulating MSC at the site of injury. Transplanted MSC can indeed leave the blood flow and transmigrate through the endothelial barrier, and reach the lesion site...

Although amyloid β protein (Aβ) has been recognized as one of the main pathological characteristics in the brain of Alzheimer's disease (AD), the effective strategies against Aβ neurotoxicity are still deficient up to now. Glucagon-like peptide 1 (GLP-1), a natural gut hormone, was found to be effective in modulating insulin signaling and neural protection, but short half-life limited its clinical application in AD treatment. CJC-1131, a newly designed GLP-1 analogue with very longer half-life, has shown good effectiveness in the treatment of type 2 diabetes mellitus (T2DM)...

BACKGROUND: Ecological momentary assessment (EMA) assesses individuals' current experiences, behaviors, and moods as they occur in real time and in their natural environment. EMA studies, particularly those of longer duration, are complex and require an infrastructure to support the data flow and monitoring of EMA completion. OBJECTIVE: Our objective is to provide a practical guide to developing and implementing an EMA study, with a focus on the methods and logistics of conducting such a study...

INTRODUCTION: Intimate partner violence is a significant public health problem, with shelters offering the predominant community-based solution. Shelters in Canada are mandated to provide a safe place, protection planning, advocacy and counseling among other services. Recently it has been noted the role of the shelter was shifting from an inpatient to outpatient model with a focus on increased integration of health and social services. This changing role of the shelter is amplified within the rural context where resources and cultural norms may be limited or incompatible with help-seeking behaviors...

The recent description of a new vibrational mating disruption method to control the leafhopper Scaphoideus titanus Ball opened questions about its possible application to other leafhopper pests. Since the prerequisite for the method's successful application is a deep knowledge of the species mating behavior and the exact role of associated signals, we conducted behavioral assays on the green leafhopper Empoasca vitis Göthe, a pest of grapevine and other crops in Europe and Asia. Laser vibrometer recordings of single and paired individuals (male and female) during a 24-hour period enabled us to detect and describe two male and one female signal...

Blast-induced neurotrauma has affected more than 300,000 service members. It is important to understand the effect of single and repeated shock-blast wave exposures on the neuropsychological behavior of soldiers, to offer them better protection, diagnostics, and treatment. Preclinical animal models and helmet design studies on human surrogate models have relied on the use of compression gas-driven shock tubes. Traditional shock tubes are so simple that if not carefully designed and operated, the test results can easily introduce detrimental artifacts clouding the conclusions...

OBJECTIVE: This study tested mediating processes hypothesized to explain the therapeutic benefit of an efficacious motivational interview (MI). The constructs of interest were motivation to change, cognitive dissonance about current drinking, self-efficacy for change, perceived young adult drinking norms, future drinking intentions, and the use of protective behavioral strategies. METHOD: A randomized controlled trial compared the efficacy of a brief MI to a time- and attention-matched control of meditation and relaxation training for alcohol use...

The translation of metallothioneins (MTs) is one of the defense strategies by which organisms protect themselves from metal-induced toxicity. MTs belong to a family of proteins comprising MT-1, MT-2, MT-3, and MT-4 classes, with multiple isoforms within each class. The main aim of this study was to determine the behavior of MT in dependence on various externally modelled environments, using electrochemistry. In our study, the mass distribution of MTs was characterized using MALDI-TOF. After that, adsorptive transfer stripping technique with differential pulse voltammetry was selected for optimization of electrochemical detection of MTs with regard to accumulation time and pH effects...

Animal medication is a behavioral strategy to resist enemies based on the use of substances from the environment. While it has been observed in several animals, whether invasive species can use medication to resist new enemies during its expansion is unknown. Here, we show that the worldwide invasive pest Drosophila suzukii performs trans-generational prophylactic medication by adapting its oviposition behavior in the presence of enemies. We find that flies preferentially lay their eggs on media containing atropine - an entomotoxic alkaloid - in the presence of parasitoids...

Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal types of tumors, and its incidence is rising worldwide. Survival can be improved when tumors are detected at an early stage; however, this cancer is usually asymptomatic, and the disease only becomes apparent after metastasis. Several risk factors are associated to this disease. Chronic pancreatitis, diabetes, and some infectious disease are the most relevant risk factors. Incidence of PDAC has increased in the last decades. It is hypothesized it could be due to other acquired risk habits, like smoking, high alcohol intake, and obesity...
