Preclinical Research The diterpene ent-dihydrotumanoic acid (DTA) was among the compounds isolated from Gymnosperma glutinosum (Spreng) Less (Asteraceae). There are no reports regarding the pharmacological effects of DTA. Cytotoxicity against cancer cells (1-250 µM), and the antibacterial (50-1400 µM) activity of DTA were evaluated using the MTT assay, and the minimum inhibitory concentration test, respectively. The antidiarrheal (1-100 mg/kg p.o.) and anti-inflammatory (2 mg/ear) effects of DTA were evaluated using castor oil and 12-O-tetradecanoylphorbol-13-acetate, respectively...

Many scorpion toxins that act on sodium channels (NaScTxs) have been characterized till date. These toxins may act modulating the inactivation or the activation of sodium channels and are named α- or β-types, respectively. Some venom toxins from Tityus obscurus (Buthidae), a scorpion widely distributed in the Brazilian Amazon, have been partially characterized in previous studies; however, little information about their electrophysiological role on sodium ion channels has been published. In the present study, we describe the purification, identification and electrophysiological characterization of a NaScTx, which was first described as Tc54 and further fully sequenced and renamed To4...

Surface waters can contain a diverse range of organic pollutants, including pesticides, pharmaceuticals and industrial compounds. While bioassays have been used for water quality monitoring, there is limited knowledge regarding the effects of individual micropollutants and their relationship to the overall mixture effect in water samples. In this study, a battery of in vitro bioassays based on human and fish cell lines and whole organism assays using bacteria, algae, daphnids and fish embryos was assembled for use in water quality monitoring...

BACKGROUND: The antiphospholipid syndrome (APS) is defined by simultaneous presence of vascular clinical events and antiphospholipid antibodies (aPL). The aPL considered as diagnostics are lupus anticoagulant and antibodies anticardiolipin (aCL) and anti-ß2 glycoprotein-I (aB2GP1). During recent years, IgA aB2GP1 antibodies have been associated with thrombotic events both in patients positive, and mainly negative for other aPL, however its value as a pro-thrombotic risk-factor in asymptomatic patients has not been well defined...

This study investigated the effects of similarity with the transgressor and the victim on the perceived immorality of the transgression. Participants read two stories describing a person that cheated on their partner and a police officer that mistreated somebody. In the first story we manipulated participants' personal similarity to the transgressor and in the second their personal similarity to the victim. In each story, participants' past situational similarity to the target character was assessed according to their previous experiences of being in the same position...

Glutamate (Glu) quantification has been performed by a combination of intracerebral microdialysis through which the samples are obtained and analyzed by high performance liquid chromatography (HPLC); its measurement requires a large expenditure of time (15-30 min per sample) and special training. Therefore, an alternative method is presented here, based on the electrochemiluminescence produced by the use of an enzymatic reactor, containing glutamate-oxidase, mixed and incubated with microdialysate from dorsal striatum (DS) and prefrontal cortex (PFC) of young rats asphyxiated during the neonatal period, under a global asphyxia model in order to test this method...

Undergraduate research experiences are a "high impact" educational practice that confer benefits to students. However, little attention has been paid to understanding faculty motivation to mentor undergraduate students through research training programs, even as the number of programs has grown, requiring increasing numbers of faculty mentors. To address this, we introduce a conceptual model for understanding faculty motivation to mentor and test it by using empirical data to identify factors that enable and constrain faculty engagement in an undergraduate research program...

BACKGROUND: Posttraumatic stress disorder (PTSD) from warzone exposure is associated with chronic and disabling social and occupational problems. However, functional impairment is rarely assessed or targeted directly in PTSD treatments, which instead focus on symptom reduction. Trauma-related contributors to diminished functioning, including guilt, shame, and anger resulting from morally compromising or loss-based war experiences, are also underemphasized. The goal of this clinical trial is to fill a substantial gap in the treatment of military-related PTSD by testing a modified Adaptive Disclosure (AD) therapy for war-related PTSD stemming from moral injury and traumatic loss focused on improving psychosocial functioning AD...

Breast Cancer Resistance Protein (BCRP) is an ATP-dependent efflux transporter linked to the multidrug resistance phenomenon in many diseases such as epilepsy and cancer, and a potential source of drug interactions. For those reasons, the early identification of substrates and non-substrates of this transporter during the drug discovery stage is of great interest. We have developed a computational non-linear model ensemble based on conformational independent molecular descriptors using a combined strategy of genetic algorithms, J48 decision tree classifiers and data fusion...

OBJECTIVE: The aim of this study was to highlight that concurrent administration of the common lipid-lowering agent fenofibrate may lead to false-positive amphetamine results in often-used immunoassay-based urine drug screens. It also aimed to show that there are significant moral and clinical challenges associated with the interpretation of such results amongst psychiatric inpatients. CONCLUSIONS: It is evident that different pathology laboratories may utilise different commercial urine drug-screen immunoassays in their toxicology analysis, with variability in the test specificities...

This study examined levels of posttraumatic stress symptoms (PTSS) and relationships between PTSS and alcohol-related outcomes in a near census of municipal firefighters. The study also assessed substance-use coping and drinking to cope as potential mediators of such outcomes. Firefighters (N = 740) completed measures that assessed PTSS, alcohol risk behaviors, alcohol problems, drinking motives, and coping with stress. Results showed that 32.4% of firefighters reported significant levels of PTSS using National Center for PTSD (2014) screening cutoff scores...

BACKGROUND: Although callous-unemotional (CU) traits have been associated with bullying among children and adolescents, relatively little is known about whether each of the three sub-constructs of CU traits-callous, uncaring, and unemotional-are associated with bullying when they are considered concurrently in the analysis. OBJECTIVE: This study was the first to examine in a single model whether callous, uncaring, and unemotional traits are directly related to the perpetration of bullying and to harm-effect moral reasoning in bullying among children as well as whether these three CU traits are indirectly related to bullying mediated by harm-effect moral reasoning...
