Childhood socioeconomic status (SES) is an important aspect of early life environment associated with later life health/health behaviors, including alcohol misuse. However, alcohol misuse is modestly heritable and involves differing etiological pathways. Externalizing disorders show significant genetic overlap with substance use, suggesting an impulsivity pathway to alcohol misuse. Alcohol misuse also overlaps with internalizing disorders, suggesting alcohol is used to cope. These differing pathways could lead to different patterns over time and/or differential susceptibility to environmental conditions, such as childhood SES...

Glenn D Walters, Dorothy L Espelage
This study was designed to address two research questions. The first research question asked whether physical abuse victimization at the hands of parents/guardians, bullying victimization at the hands of peers, and the abuse x bullying interaction encouraged early involvement in substance misuse. The second research question inquired as to whether the victimization‒substance misuse relationship was mediated by variables proposed by various theories and research studies-specifically, cognitive impulsivity, negative affect, and low self-esteem...

Accurate prediction of the sorption of perfluoroalkyl substances (PFASs) in soils is essential for environmental risk assessment. We investigated the effect of solution pH and calculated soil organic matter (SOM) net charge on the sorption of 14 PFASs onto an organic soil as a function of pH and added concentrations of Al3+ , Ca2+ and Na+ . Often, the organic C-normalized partitioning coefficients (KOC ) showed a negative relationship to both pH (Δlog KOC /ΔpH = -0.32 ± 0.11 log units) and the SOM bulk net negative charge (Δlog KOC  = -1...

Novel excipients are indispensable in development of modern, advanced drug delivery systems and biotechnology-derived drugs. Although numerous novel excipients are developed for pharmaceutical use, they are not frequently seen in medicinal products due to the strict regulatory requirements and perception that their use makes new product evaluation more complex with risk of delays in the approval process. Regulators regard novel excipients as new substances and whenever new excipient is used in a formulation it must be subjected to full evaluation, similarly to the one required for new active substance...

BACKGROUND: Hand antiseptics are of great importance in the prevention of nosocomial infections. Due to the frequent occurrence of adenoviral epidemic keratoconjunctivitis outbreaks in our hospital, we needed to detect the efficiency of alcohol-based-solutions on adenovirus. AIM: To investigate the efficacy of alcohol-based-solutions, that commonly found in hand-antiseptics against adenovirus 8, 19 and 37. METHODS: We investigated the efficacy of ethanol, isopropanol, chlorhexidine-digluconate, n-butanol and different combinations of these antiseptics on adenovirus serotypes that typically cause to epidemic keratoconjunctivitis...

The ill-defined term "energy drink" includes a disparate group of products (beverages, shots, concentrates, and workout powders) having large differences in caffeine content and concentration and intended use. Hence, inaccurate conclusions may be drawn when describing adverse events associated with "energy drinks". The FDA is considering new regulation of these products but product specificity is needed to evaluate safety. To help address this, we queried Texas Poison Center Network data for single substance exposures to "energy drinks" from 2010 to 2014, then analyzed adverse events by product type...

INTRODUCTION: Portal vein embolization or ligation (PVE/PVL) is part of most multi-stage liver procedures in the case of low future liver remnant volume (FLRV). PVE initiates compensatory hypertrophy of non-occluded liver parenchyma. This hypertrophy is stimulated by an increased volume of portal blood in the non-occluded veins. PVE results in adequate FLRV growth necessary for resection only in 63-96% patients. The aim of this publication is to summarize the possibilities of influencing liver regeneration after PVE/PVL in an experiment using cytokines (TNF-α, IL-6), a monoclonal antibody against TGF-β1 (MAB TGF-β1) and mesenchymal stem cells (MSC)...

Although adoptive families have been shown to provide a protective context for human development, some adopted children and adolescents are at increased risk for psychological adjustment problems. On the other hand, little is known about psychological adjustment of young adult adoptees. The aim of this study is to analyze the mental health and legal substance consumption (tobacco and alcohol) of young adults (n = 134) who were domestically adopted by Spanish families. Young adults showed significantly worse scores on the Symptom Check-List-90-R (Derogatis, 1975) and also more substance use than did the Spanish general population, but fewer difficulties than did the clinical population...

Cannabis is the most commonly used illicit drug in the United States, and craving for cannabis is related to cannabis use. Exercise has been demonstrated to reduce craving for substances. To examine the effects of exercise on cannabis craving, we conducted a 3-week within-subject crossover experiment. Young-adult men (n = 35) and women (n = 11), age 18-25 years (M = 20.76, SD = 1.68), who regularly (≥3 times per week) used cannabis participated in a cue exposure paradigm to stimulate craving. After each of three separate craving inductions, they completed a 10-min bout of exercise that varied in intensity (rest, moderate, vigorous)...

BACKGROUND: Propolis is multicomponent substance collected by honeybees from various plants. It is known for numerous biological effects and is commonly used as ethanolic extract because most of active substances of propolis are ethanol-soluble. However, water-based propolis extracts could be applied more safely, as this solvent is more biocompatible. On the other hand, water extracts has significantly smaller range and quantity of active compounds. The extraction power of water could be enhanced by adding co-solvent which increases both solubility and penetration of propolis compounds...

BACKGROUND: Mexico recently enacted drug policy reform to decriminalize possession of small amounts of illicit drugs and mandated that police refer identified substance users to drug treatment. However, the economic implications of drug treatment expansion are uncertain. We estimated the costs of opioid substitution therapy (OST) provision in Tijuana, Mexico, where opioid use and HIV are major public health concerns. METHODS: We adopted an economic health care provider perspective and applied an ingredients-based micro-costing approach to quantify the average monthly cost of OST (methadone maintenance) provision at two providers (one private and one public) in Tijuana, Mexico...

The emergence of designer drugs as substances of abuse has seen a dramatic increase over the last few years. Customs officials are responsible for the control of products entering the European Union (EU) market. This control applies to chemicals in general, pharmaceutical products and medicines. Numerous products imported from non-EU countries, often -declared as 'bath salts' or 'fertilizers', may in fact contain new psychoactive substance (NPS). These are not necessarily controlled under international law, but are subject to monitoring in agreement with EU legislation...

Dams have profound impacts on river ecosystems, amongst them inundation of land, altered dynamics of the water body or uprising reservoir backwaters influencing tributary or upstream river sections. Along the outstandingly ecologically important Yangtze River in China, the Three Gorges Reservoir (TGR) is the largest project, covering an area of 1080 km2 . From the beginning, the dam-project came in for criticism on increasing environmental risks due to sub-merging former industrial and urban areas. We simulated dynamics of biotic and abiotic components of the TGR ecosystem (trophic guilds of aquatic organisms, hydrodynamics, nutrients), as well as the behaviour of the herbicidal substance propanil and its metabolites 3,4-Dichloroaniline (DCA) and 3,3',4,4'-tetrachloroazoxybenzene (TCAB)...

Oxidative degradation of six representative microcystins (MCs) (MC-RR, -LR, -YR, -LF, -LW and -LA) by potassium permanganate (KMnO4; Mn(VII)) was investigated, focusing on the temperature- and pH-dependent reaction kinetics, the effect of dissolved organic matter (DOM), and the oxidation mechanisms. Second-order rate constants for the reactions of the six MCs with Mn(VII) (kMn(VII),MC) were determined to be 160.4-520.1 M-1 s-1 (MC-RR > -LR  -YR > -LF  -LW > -LA) at pH 7.2 and 21°C. The kMn(VII),MC values exhibited activation energies ranging from 15...

NEW FINDINGS: What is the central question of this study? In human articular joints, the synovial fibroblast HSF cell population has essential functions including secretion of lubricants. We address some remaining questions concerning activation-secretion coupling by characterizing the main [Ca2+ ]i signalling pathways activated by ATP. What is the main finding and its importance? In HSF ATP acts through a linked G-protein (Gq ) and phospholipase C signalling mechanisms to produce IP-3 which markedly enhances release of Ca2+ from the endoplasmic reticulum...

BACKGROUND: Substance misuse persists as a major public health issue worldwide with significant costs for society. The development of interventions requires methodologically sound studies to explore substance misuse causes and consequences. This Cohort description paper outlines the design of the Belfast Youth Development (BYDS), one of the largest cohort studies of its kind in the UK. The study was established to address the need for a long-term prospective cohort study to investigate the initiation, persistence and desistance of substance use, alongside life course processes in adolescence and adulthood...

With the development of new biologics and bioconjugates, storage and preservation have become more critical than ever before. Lyophilization is a method of cell and protein preservation by removing a solvent such as water from a substance followed by freezing. This technique has been used in the past and still holds promise for overcoming logistic challenges in safety net hospitals with limited blood banking resources, austere environments such as combat, and in mass casualty situations where existing resources may be outstripped...
