Biodegradable and bioresorbable polyesters (BBPEs) are a widespread class of aliphatic polymers with a plethora of applications in the medical field. Some reports speculate that these polymers have intrinsic antibacterial activity as a consequence of their acidic degradation by-products. The release of organic acids as a result of the hydrolytic degradation of BBPEs in vivo and the resulting pH...

BACKGROUND Rates of substance use among adolescents have increased in the 1990s, however little is known about current patterns of substance use among youths entering adulthood. METHODS We studied sex and age-specific rates of substance use (tobacco, alcohol, cannabis, other illicit drugs, inhalants and psychotropic medications) in a large sample of French youths aged 12-26 years (the GAZEL Y...

One of the most important factors of successful substance abuse treatment is the early start of the same treatment. Recent selection method for identification of Croatian adolescents in the substance abuse risk that has been using drug tests from urine samples, has been simple and exact on the one hand, but on the other, has been very rare and usually guided by the pressure of parents or the co...

This report reviews studies of psychosocial interventions for people with co-occurring substance use disorder and severe mental illness. We identified 45 controlled studies (22 experimental and 23 quasi-experimental) of psychosocial dual diagnosis interventions through several search strategies. Three types of interventions (group counseling, contingency management, and residential dual diagnos...

Comprehensive intervention for homeless, street living youth that addresses substance use, social stability, physical and mental health issues has received very little attention. In this study, street living youth aged 14-22 were recruited from a drop-in center and randomly assigned to the Community Reinforcement Approach (CRA) or treatment as usual (TAU) through a drop-in center. Findings show...

1. The effect of the tachykinin dodecapeptide kassinin, which has been extracted from the skin of several African frogs, on somatostatin release was examined in the rat and compared with that of the neuropeptide substance P. 2. Equimolar doses of the two peptides were injected intravenously and the animal killed at specified intervals after injection. Somatostatin was measured by a specific rad...

Many recovering substance users report quitting drugs because they wanted a better life. The road of recovery is the path to a better life but a challenging and stressful path for most. There has been little research among recovering persons in spite of the numbers involved, and most research has focused on substance use outcomes. This study examines stress and quality of life as a function of ...

Introduction. For new synthesized pharmacologically active compounds, already at the stage of standardization, it is necessary to develop methods for determining their quality indicators, normalized by a pharmacopoeial article pharmaceutical substances. One these indicators residual organic solvents, analysis which chromatographic are suitable, example, gas-liquid chromatography. Aim. To condit...
