OBJECTIVE: Among young children excessive externalizing behaviors often predict adolescent conduct and substance use disorders. Adolescents with those disorders show aberrant brain function when choosing between risky or cautious options. We therefore asked whether similarly aberrant brain function during risky decision-making accompanies excessive externalizing behaviors among children, hypothesizing an association between externalizing severity and regional intensity of brain activation during risky decision-making...

Forest fires can be a source of contamination because, among others, of the use of chemicals to their extinction (flame retardants, FRs), or by the production of Polycyclic Aromatic Hydrocarbons (PAHs) derived from high temperature alteration of organic matter. Up to our knowledge, this study is the first to assess the direct (PAHs 16 on the USA EPA's priority list), and indirect [tri- to hepta- brominated diphenyl ethers (PBDEs), organophosphorus flame retardants (PFRs) and perfluoroalkyl substances (PFASs)] contamination related to forest fires...

BACKGROUND: Clomiphene is normally used in women with ovulatory dysfunction. In men, it is used off label in some cases of infertility. Psychological adverse effects are reported in women but very few in men. CASE: A 34 year-old man treated with clomiphene for oligoteratospermia presented anxiety, decreased appetite, and depressed mood making him unable to function properly at work, five days after initiation of therapy. Symptoms required reduction followed by discontinuation of treatment four days later because of absence of improvement...

The biopharmaceutical industry produces non-sterile and/or low-bioburden intermediates and bulk biologics (i.e. Drug Substances) using bioburden controlled processes in accordance to Q7A and Annex 2. In many cases, single mold isolation events have received a high level of scrutiny; the goal of this paper is to challenge this paradigm and provide the rationale for an enhanced control approach that focuses on trending of mold species as microbial indicators rather than on single isolation events. Molds, can also be part (in much lower numbers) of the normal microbial population of a biologics manufacturing facility and, therefore, mold isolation is not an unexpected event in non-aseptic processing environments...

New psychoactive substances (NPS) are a new breed of synthetically produced substances designed to mimic the effects of traditional illegal drugs. Synthetic cannabinoids and synthetic cathinones are the two most common groups, which try to mimic the effects of the natural compounds (9)Δ-tetrahydrocannabinol and cathinone, respectively. Similarly, synthetic tryptamines are designer compounds which are based on the compounds psilocin, N,N-dimethyltryptamine and 5-methoxy-N,N-dimethyltryptamine found in some mushrooms...

REVIEW
Adrianne R Wilson-Poe, Jose A Moron
In 2014, drug overdose surpassed automobile accidents as the number one cause of accidental death for the first time in US history. The overdose epidemic is largely driven by opioids, and genuine prescription opioid analgesics play the biggest role in this phenomenon. Despite advancements in abuse deterrent formulations, prescription drug monitoring programs, and clinical assessments for the detection of abuse potential, drug overdoses continue to escalate. The CDC has recently issued new guidelines for opioid prescription, yet even these recommendations have their shortcomings...

Brivaracetam (BVR) is a novel antiepileptic drug (AED), approved clinically for the treatment of partial onset seizures in adults and adolescents. It has some abuse potential and assigned to Schedule V category under the Controlled Substance Act by the Drug Enforcement Administration. Being an AED and drug of abuse, a sensitive and robust assay is necessary for determination of BVR in biological fluids. Herein, we report a sensitive and validated UPLC-MS/MS assay for identification and quantification of BVR in plasma samples...

We report the clinical presentation, radiography, and management outcomes of autoenucleations (AE). Charts of 7 patients evaluated at 4 institutions with AE were reviewed. Four males and three females had a mean age of 50 years (range 26-72 years). The etiologies were psychosis secondary to underlying mental illness (6, 88%) and substance use (1, 12%), and the mechanism was largely blunt digital injury (6, 88%). Three (43%) AE patients suffered bilateral enucleations. Common concomitant injuries included eyelid lacerations (5, 71%) and optic nerve avulsion (3, 43%)...

Cell-free and concentrated ascites reinfusion therapy (CART) is a very useful treatment method for refractory ascites but is difficult for many hospitals to employ due to its need for specialized equipment. We have therefore developed drop-type with adjustable concentrator CART (DC-CART) that uses a drop-type filtration mechanism and requires only a simple pump and pressure monitor for its concentration process. Easy adjustment of ascites concentration is possible through a recirculation loop, and filter membrane washing is aided by DC-CART's external pressure-type filtration to enable the processing of any quality or quantity of ascites...

FOCUS models are used in the European regulatory risk assessment (RA) to predict individual pesticide concentrations in edge-of-field surface waters. The scenarios used in higher tier FOCUS simulations were mainly based on Central/North European, and work is needed to underpin the validity of simulated exposure profiles for Mediterranean agroecosystems. In addition, the RA of chemicals are traditionally evaluated on the basis of single substances although freshwater life is generally exposed to a multitude of pesticides...

Extra-cellular polymeric substances (EPS) are a major cause of membrane fouling in membrane bioreactors (MBRs). In this study, an anoxic-oxic membrane bioreactor (A/O-MBR) was run continuously for 98 days. The runs were divided into three stages according to hydraulic retention time (HRT) (11.8, 12.5 and 14.3 h, respectively). EPS were extracted from the reactor under the different HRTs. A quartz crystal microbalance with dissipation monitoring (QCM-D) and Fourier transform infrared (FT-IR) were used to study the adherence layer structures and the adsorption behaviours of EPS on the membrane surface...

The use of pesticides in Mexican agriculture creates an interest in learning about the presence of these substances in different environmental matrices. Glyphosate (GLY) is an herbicide widely used in the state of Campeche, located in the Mayan zone in the western Yucatan peninsula. Despite the fact that GLY is considered a non-toxic pesticide to humans, its presence in water bodies through spillage, runoff, and leaching are a risk to human health or biota that inhabit these ecosystems. In the present study, glyphosate residues were determined in groundwater, bottled drinking water, and the urine of subsistence farmers from various localities of the Hopelchén municipality in Campeche...

Up-flow column percolation tests are used at laboratory scale to assess the leaching behavior of hazardous substance from contaminated soils in a specific condition as a function of time. Monitoring the quality of these test results inter or within laboratory is crucial, especially if used for Environment-related legal policy or for routine testing purposes. We tested three different sandy loam type soils (Soils I, II and III) to determine the reproducibility (variability inter laboratory) of test results and to evaluate the difference in the test results within laboratory...
