A growing literature exists on neural correlates of treatment outcome. However, different types-or components of-treatment have distinct theorized mechanisms of action. And it is not yet known how changes in neural activity across treatment relate to engagement in different treatment components. Participants with cocaine use disorders in a randomized clinical trial received cognitive-behavioral therapy (CBT) plus, in a 2 × 2 design, contingency management (CM) or no CM, and disulfiram or placebo. Participants performed a functional MRI Stroop task, a measure of cognitive control, at the beginning of and after the 12-week treatment...

Hospital wastewaters contain large amounts of pharmaceutical residues, which may eventually be discharged into the aquatic environment through wastewater treatment plants, raising the question of their impact on human and environmental health. This has prompted the launch of several monitoring studies into the most commonly administered compounds in urban wastewater. The aim of this study was, therefore, to explore the cytotoxic potential of wastewaters samples collected from seven hospitals in Tunisia. The physicochemical analyses showed a large fluctuation of certain parameters in the collected samples, such as chemical oxygen demand (ranged from 860 to 1720 mg L(-1)), biochemical oxygen demand (ranged from 385 to 747 mg L(-1)), total organic carbon (ranged from 256 to 562 g L(-1)), total suspended solids (ranged from 905 to 1450 mg L(-1)), conductivity (ranged from 3...

Two species of edible clams Venerupis aurea laeta and Cerastoderma edule glaucum from Ganzirri Lake (Sicily, Italy) were investigated to determine OCP and PCB residues by GC-MS. Thirty-five samples were examined for two years in order to perform: a) their actual contamination; b) the daily dietary exposure of seafood consumers to the pollutants in question. In all the clams analysed in this study, PCB and OCP (4,4'-DDE) residues are always below the limits fixed by law. It seems that there is some seasonality of concentrations observed...

The article deals with the use of mixed anhydrides for the synthesis of fatty esters. Both aliphatic and aromatic acids are involved, indicating different behaviors according to the chain length of the aliphatic acid. We describe a novel and efficient method for the synthesis of fatty esters by the esterification reaction of primary, secondary and tertiary alcohols with mixed carboxylic-palmitic anhydrides using resin Amberlyst-15 as heterogeneous acid catalyst. Influence of various reaction parameters such as molar ratio (anhydride/alcohol), catalyst amount, type of alcohol and type of mixed anhydride were studied to optimize the conditions for maximum yield...

Dissociation of the complex of a ligand and a protein usually follows the kinetic profile of the first order process and the rate of dissociation is not affected by the presence of competitive ligands. We discovered that dissociation of the complex between a bifunctional ligand and a protein kinase (the catalytic subunit of cAMP-dependent protein kinase), an enzyme possessing 2 different substrate binding sites, was accelerated (facilitated) over 50-fold in the presence of competitive ligands at higher concentrations...

Carbapenems are β-lactam antibiotics with a broad spectrum of activity and are usually considered the last resort for the treatment of severe infections caused by multidrug-resistant pathogens. The clinically most significant carbapenemases are KPC, NDM, and OXA-48-like enzymes, whose genes have been increasingly reported worldwide in members of the family Enterobacteriaceae. In this study, we quantified the abundance of these genes in wastewater effluents from different Tunisian hospitals. The blaNDM and blaOXA-48-like genes were detected at similar concentrations in all hospital wastewater effluents...

BACKGROUND: It is established that the standard treatment for lithiasic acute cholecystitis is the laparoscopic cholecystectomie. However, the question of the timing of cholecystectomy remains controversial. AIM: To compare early laparoscopic cholecystectomies (within 72 hours of symptom onset) and delayed laparoscopic cholecystectomies (beyond 72 hours) for lithiasic acute cholecystitis in terms of intra-operative difficulties and post-operative complications. METHODS: The patients operated on for acute cholecystitis, between January 2007 and December 2012, were included in a retrospective study...

Gastrointestinal and gynecological malignancies disseminate in the peritoneal cavity - a condition known as peritoneal carcinomatosis (PC). Intraperitoneal (IP) administration can be used to improve therapeutic index of anticancer drugs used for PC treatment. Activity of IP anticancer drugs can be further potentiated by encapsulation in nanocarriers and/or affinity targeting with tumor-specific affinity ligands, such as tumor homing peptides. Here we evaluated a novel tumor penetrating peptide, linTT1 (AKRGARSTA), as a PC targeting ligand for nanoparticles...

High demand for inhibitors regulating the activity of protein kinases has stimulated the quest for high throughput and reliable compound screening assays. Here we introduce a method applying a non-metal photoluminescent probe ARC-Lum(Fluo) for determination of dissociation constants of competitive inhibitors of protein kinases. Employing a single probe instead of a combination of antibody and fluorescent tracer makes the assay simpler, cheaper, and more accurate than several other inhibitor-screening technologies...

Aerobic glycolysis supports proliferation through unresolved mechanisms. We have previously shown that aerobic glycolysis is required for the regulated proliferation of cerebellar granule neuron progenitors (CGNP) and for the growth of CGNP-derived medulloblastoma. Blocking the initiation of glycolysis via deletion of hexokinase-2 (Hk2) disrupts CGNP proliferation and restricts medulloblastoma growth. Here, we assessed whether disrupting pyruvate kinase-M (Pkm), an enzyme that acts in the terminal steps of glycolysis, would alter CGNP metabolism, proliferation, and tumorigenesis...

Molecular MRI allows in vivo detection of vascular cell adhesion molecules expressed on inflamed endothelium, which enables detection of specific targets for anti-neuroinflammatory treatment. We explored to what extent MR contrast agent targeted to intercellular adhesion molecule-1 (ICAM-1) could detect endothelial- and leukocyte-associated ICAM-1 expression at different stages after experimental stroke. Furthermore, we assessed potential interfering effects of ICAM-1-targeted contrast agent on post-stroke lesion growth...

A defect in adrenal steroidogenesis may cause a disorder of sex development (DSD). Importantly, DSD of adrenal origin is not restricted to a genital phenotype but is in most cases accompanied by mild to severe impairment in glucocorticoid and/or mineralocorticoid synthesis. If a patient is suspected of DSD of adrenal origin evaluation of glucocorticoid and mineralocorticoid metabolism is therefore essential to provide adequate medical care in the case of a severe and potentially life-threatening insufficiency...
