Recent research on psychotherapy has focused on the development and evaluation of disorder-specific treatments. Even though much progress has been made, treatments have not yet reached an ideal level of effectiveness. One reason for this could be the systematic overlap and high comorbidity between mental disorders. Consequently, a new trend ...

Intracellular pathogens like Salmonella evade host phagocytic killing by various mechanisms. Classical antimicrobial therapy requires multiple dosages and frequent administration of drugs for a long duration. Intracellular delivery of antimicrobials using nanoparticle may effectively devise therapies for bacterial infections. This review will address the mechanisms used by Salmonella to avoid ...

Since prolonged cold preservation of the heart deteriorates the outcome of heart transplantation, a more protective preservation solution is required. We therefore developed a new solution, named Dsol, and examined whether Dsol, in comparison to UW, could better inhibit myocardial injury resulting from prolonged cold preservation. Syngeneic heterotopic heart transplantation ...

Most humans lack a functional CASP12 gene, with the nonfunctional variant (CASP12p1), found in 100% of the Caucasian and east Asian population, and in approximately 80% of people of African descent. However, 20% of Africans carry an intact allele of CASP12, which produces a full-length pro-enzyme and increases the risk ...

Fluorescent graphene-based materials, labelled as a sort of fluorescent carbon-based nanomaterial, have drawn increasing attention in recent years. When the size and structure of graphene were controlled properly, photoluminescence was induced in graphene, resulting in the so-called fluorescent graphene (FG). FG has a size-, defect-, and wavelength-dependent luminescence emission, which ...

Anesthesia is safe in most patients. However, anesthetics reduce functional residual capacity (FRC) and promote airway closure. Oxygen is breathed during the induction of anesthesia, and increased concentration of oxygen (O(2) ) is given during the surgery to reduce the risk of hypoxemia. However, oxygen is rapidly adsorbed behind closed ...

Aim: In subjects with metabolic syndrome (MetS) endothelial dysfunction is a very consistent finding. Processes leading to endothelial dysfunction and atherosclerosis involve the altered control of subclinical inflammation by innate immune defenses that possibly include mannose-binding lectin (MBL). We investigated the associations of MBL with traits of MetS and early ...

Among the asexual reproductive modes, androgenesis is probably one of the most astonishing and least studied mechanisms. In this 'paternal monopolization', the maternal nuclear genome fails to participate in zygote development and offspring are paternal nuclear clones. Obligate androgenesis is known in only a few organisms, including multiple species of ...

The factors that control the chemoselectivity of palladium-catalyzed cyclization reactions of (2-iodoanilino)carbonyl compounds have been explored by an extensive experimental computational (DFT) study. It was found that the selectivity of the process, that is, the formation of fused six- versus five-membered rings, can be controlled by the proper selection of ...

Bronchodilators represent the mainstay of symptomatic treatment for chronic obstructive pulmonary disease (COPD). The principal bronchodilator agents are β(2)-agonists, anticholinergics and methylxanthines, used singly or in combination. Indacaterol is a novel long-acting β(2)-agonist for maintenance bronchodilator treatment of airflow obstruction in patients with COPD, approved in December 2009 by the ...

In an interferometer-based fluorescence microscope, a beam splitter is often used to combine two emission wavefronts interferometrically. There are two perpendicular paths along which the interference fringes can propagate and normally only one is used for imaging. However, the other path also contains useful information. Here we introduced a second ...

We present here an initial characterization of ATP binding cassette (ABC) transporter function and regulation at the blood-spinal cord barrier. We isolated capillaries from rat spinal cords and studied transport function using a confocal microscopy-based assay and protein expression using western blots. These capillaries exhibited transport function and protein expression ...

Astrocytes are implicated in information processing, signal transmission, and regulation of synaptic plasticity. Aquaporin-4 (AQP4) is the major water channel in adult brain and is primarily expressed in astrocytes. A growing body of evidence indicates that AQP4 is a potential molecular target for the regulation of astrocytic function. However, little ...
