Disruption of newly identified genes in the pathogen Candida albicans is a vital step in determination of gene function. Several gene disruption methods described previously employ long regions of homology flanking a selectable marker. Here, we describe disruption of C. albicans genes with PCR products that have 50 to 60 bp of homology to a genomic sequence on each end of a selectable marker. W...

The present study was designed to investigate the effect of κ-opioid receptor stimulation with U50,488H on endothelial function and underlying mechanism in rats with hypoxic pulmonary hypertension (HPH). Chronic hypoxia-induced HPH was simulated by exposing the rats to 10% oxygen for 2 wk. After hypoxia, mean pulmonary arterial pressure (mPAP), right ventricular pressure (RVP) and right ventric...

The hygromycin phosphotransferase gene was fused in-frame with the herpes simplex virus type 1 thymidine kinase gene. The resulting fusion gene (termed HyTK) confers hygromycin B resistance for dominant positive selection and ganciclovir sensitivity for negative selection and provides a means by which these selectable phenotypes may be expressed and regulated as a single genetic entity.

Pulmonary hypertension (PH) remains a life-limiting disease characterized by pulmonary vascular remodelling due to aberrant proliferation and migration of pulmonary artery smooth muscle cells (PASMCs), thus leading to raised pulmonary arterial pressure and right ventricular hypertrophy. Secreted glycoprotein follistatin-like 1 (FSTL1) has been reported to ameliorate tissue remodelling in cardio...

The effect of drugs, disease and other perturbations on mRNA levels are studied using gene expression microarrays or RNA-seq, with the goal of understanding molecular effects arising from the perturbation. Previous comparisons of reproducibility across laboratories have been limited in scale and focused on a single model. The use of model systems, such as cultured primary cells or cancer cell l...

The use of positive selectable marker genes is widespread in plant genetic transformation allowing transgenic cells to grow while repressing non-transgenic cells. Negative selectable markers, on the contrary, allow the repression or ablation of transgenic cells. The codA gene of Escherichia coli encodes cytosine deaminase that hydrolyzes 5-fluorocytosine (5-FC) into the cytotoxic compound 5 flu...

Seventy-four patients with hypertensive putaminal hemorrhage (HPH) were followed at least 6 months after treatment and estimated by ADL. They were graded according to the state of consciousness on admission. The grading consists of 6 grades: Grade 1, fully conscious; Grade 2, somnolent; Grade 3, stuporous; Grade 4, semi-comatose; and Grade 5, deeply comatose. Removal of HPH was performed in 18 ...

Health promoting hospitals (HPH) is a concept for hospital development that builds upon the health promotion concept of the WHO Ottawa Charter for health promotion, where the reorientation of health care services is considered as one of five major action areas for an overall health promotion development. The article outlines what such a re-orientation may mean for the main hospital functions. T...

In the valorisation of fruit and vegetable by-products by high pressure homogenization (HPH) into texturizing ingredients, source by-product is an important determining factor. This study aims to demonstrate potential citrus residues after acidic pectin extraction (AR) investigate differences between species (lemon, orange, grapefruit) parts (peel pulp) as residues. Based on results, favourable...
