Background: There has been growing interest in the potential of emerging internet-delivered psychological treatments for supporting the mental health needs of university students. However, no large-scale prospective effectiveness trials examining their real-world potential have been reported.
Objective: The aim of the current study was to evaluate the acceptability and effectiveness of a brief, 5-week, internet-delivered and therapist-guided intervention for anxiety and depression, when delivered as part of routine care by a university counselling service.
Objectives: To implement an injury recording protocol in a junior elite Australian Football competition and determine the injury profile of this population.
Design: Longitudinal cohort study.
Methods: Players from an elite Under 18 Australian Football competition were tracked throughout one football season in terms of participation or non-participation in the football competition.
Here we describe lentivirus-infected cell microarrays for the high-throughput screening of gene function in mammalian cells. To create these arrays, we cultured mammalian cells on glass slides 'printed' with lentiviruses pseudotyped as vesicular stomatitis virus glycoprotein, which encode short hairpin RNA or cDNA. Cells that land on the printed 'features' become infected with lentivirus, creating a living array of stably transduced cell clusters within a monolayer of uninfected cells.

Here we describe the development of living-cell microarrays for screening large collections of RNAi-inducing double-stranded RNAs (dsRNAs) in Drosophila cells. The features of the microarrays consist of clusters of cells 200 mum in diameter, each with an RNAi-mediated depletion of a specific gene product.

This is mainly due to the unquestionable advantage of weak spin-orbit and hyperfine interactions in organic molecules, which leads to the possibility of preserving spin-coherence over times and distances much longer than in conventional metals or semiconductors. Here we demonstrate theoretically that organic spin valves, obtained by sandwiching an organic molecule between magnetic contacts, can show a large bias-dependent magnetoresistance and that this can be engineered by an appropriate choice of molecules and anchoring groups.

We developed a microarray-based system for screening small molecules in mammalian cells. This system is compatible with image-based screens and requires fewer than 100 cells per compound. Each compound is impregnated in a 200-microm-diameter disc composed of biodegradable poly-(D),(L)-lactide/glycolide copolymer.

Consequently, we sought to determine which bFGF isoforms and levels initiate angiogenesis in nude mice peritoneums.

Methods And Materials: Nude mice peritoneums were incubated with HAEC (CW = control; TW = gas-plasma treated) or polymer scaffolds (Cp = control; Tp = treated) for 12, 24 and 72 days. Cytoplasmic and nuclear protein fractions were isolated using NER, electrophoresized using NuPAGE-MES and analyzed by WesternBreeze Chemiluminescent.

DNA microarrays and, more recently, protein microarrays, have become important tools for high-throughput genomic and proteomic studies. Transfected cell microarrays are a complementary technique in which array features comprise clusters of cells overexpressing defined cDNAs. Complementary DNAs cloned in expression vectors are printed on microscope slides, which become living arrays after the addition of a lipid transfection reagent and adherent mammalian cells.

Background: Protection of the distal microvasculature with a balloon occlusion and aspiration system has been shown to reduce atherothrombotic embolization and peri-procedural myocardial infarction (MI) after percutaneous coronary intervention (PCI) in SVGs. The safety, efficacy, and technical factors relating to procedural success with filter-based distal protection devices are unknown.
Cell microarrays are a recent addition to the set of tools available for functional genomic studies. Each cell microarray is a slide with thousands of cell clusters that are each transfected with a defined DNA, which directs either the overproduction or the inhibition of a particular gene product. By using a range of detection assays, the phenotypic consequences of perturbing each gene in mammalian cells can be probed in a systematic, high-throughput fashion.

Histologic immaturity of the tissues of the reproductive system can interfere with the interpretation of compound-related effects on the reproductive organs. In female cynomolgus macaques, determination of sexual maturity is simplified by the presence of a menstrual cycle.
