The impact of mental illness on cardiac outcomes: a review for the cardiologist.
Traditional cardiac risk factors, such as smoking, hypertension and obesity, are widely accepted contributors to the onset and progression of cardiovascular disease (CVD), one of the foremost causes of morbidity and mortality worldwide. Largely overlooked, however, is the impact of mental health on cardiac disease. Fro...

Podocalyxin selectively marks erythroid-committed progenitors during anemic stress but is dispensable for efficient recovery.
Podocalyxin expression on Ter119(+) erythroblasts is induced following administration of erythropoietin (Epo) or phenylhydrazine treatment, but is notably absent on committed erythroid progenitors during homeostatic red cell turnover. Following high-dose Epo administration in vivo, podocalyxin surface expression is upr...

An 11-year-old female, presented with a cervical myelomeningocele. Interestingly, the myelomeningocele sac was seen to contain a meningioma. There are no aetiological factors in the embryogenetic period that would lead to such a combination of lesions. In our opinion, the meningioma appeared in a later period because o...

The self-thinning process in mangrove Kandelia obovata stands.
The self-thinning process was monitored in crowded Kandelia obovata Sheue, Liu & Yong stands over four years. The frequency distribution of tree phytomass was an L-shape, which was kept over the experimental period. Spearman's rank correlation coefficient for phytomass decreased as the time span of the comparison b...

Oral cyclosporine A--the current picture of its liposomal and other delivery systems.
The discovery of cyclosporine A was a milestone in organ transplantation and the treatment of autoimmune diseases. However, developing an efficient oral delivery system for this drug is complicated by its poor biopharmaceutical characteristics (low solubility and permeability) and the need to carefully monitor its leve...

Ladder-like amplification of the type I interferon gene cluster in the human osteosarcoma cell line MG63.
The organization of the type I interferon (IFN) gene cluster (9p21.3) was studied in a human osteosarcoma cell line (MG63). Array comparative genomic hybridization (aCGH) showed an amplification of approximately 6-fold which ended at both ends of the gene cluster with a deletion that extended throughout the 9p21.3 band...

Frontal analysis microchip capillary electrophoresis to study the binding of ligands to receptors derivatized on magnetic beads.
The model binding of the glycopeptide antibiotic teicoplanin (Teic) from Actinoplanes teichomyceticus, immobilized on magnetic microspheres, to D-Ala-D-Ala terminus peptides was assessed using microchip capillary electrophoresis (MCE) with continuous frontal analysis (FA). Teic is closely related to vancomycin (Van), h...

Surfactant-induced conformational transition of amyloid beta-peptide.
Accumulating evidence suggests that Abeta(1-42)-membrane interactions may play an important role in the pathogenesis of Alzheimer's disease. However, the mechanism of this structural transition remains unknown. In this work, we have shown that submicellar concentrations of sodium dodecyl sulfate (SDS) can provide a min...

Chick embryo chorioallantoic membrane model systems to study and visualize human tumor cell metastasis.
Since their introduction almost a century ago, chick embryo model systems involving the technique of chorioallantoic grafting have proved invaluable in the in vivo studies of tumor development and angiogenesis and tumor cell dissemination. The ability of the chick embryo's chorioallantoic membrane (CAM) to efficiently ...

Sudden unexpected death in an infant with L-2-hydroxyglutaric aciduria.
Inherited metabolic disorders are the cause of a small but significant number of sudden unexpected deaths in infancy. We report a girl who suddenly died at 11 months of age, during an intercurrent illness. Autopsy showed spongiform lesions in the subcortical white matter, in the basal ganglia, and in the dentate nuclei...

Cystic fibrosis, aminoglycoside treatment and acute renal failure: the not so gentle micin.
Aminoglycosides have a wide spectrum of gram-negative anti-bacterial activities and are available at low cost, which makes them commonly used drugs, especially for patients with cystic fibrosis (CF), who often suffer from chronic lung infections from Pseudomonas aeruginosa. Unfortunately, this treatment seems to have r...

Resolving discogenic pain.
Recent basic science studies on discogenic low back pain have provided new knowledge about this condition. This paper reviews some of these results and presents an overview of the following findings. The rat lumbar intervertebral disk may be innervated non-segmentally through the paravertebral sympathetic nerve and seg...

A model for transcutaneous current stimulation: simulations and experiments.
Complex nerve models have been developed for describing the generation of action potentials in humans. Such nerve models have primarily been used to model implantable electrical stimulation systems, where the stimulation electrodes are close to the nerve (near-field). To address if these nerve models can also be used t...

Polymorphisms of Saccharomyces cerevisiae genes involved in wine production.
The setting up of new molecular methods for Saccharomyces cerevisiae typing is valuable in enology. Actually, the ability to discriminate different strains in wine making can have a benefit both for the control of the fermentation process and for the preservation of wine typicity. This study focused on the screening of...

Argon plasma coagulation and gastric bypass--a novel solution to stomal dilation.
A patulous gastro-enterostomy after gastric bypass is a common cause of poor restriction and poor weight loss. Revisional surgery is an option but may be hazardous. This case report highlights the use of argon plasma coagulation by flexible endoscopy to reduce stomal size, improve restriction, and avoid revisional surg...

Novel role of toll-like receptor 3, RIG-I and MDA5 in poly (I:C) RNA-induced mesothelial inflammation.
Viral inflammation and infection of mesothelial cells (MC) are a major problem in several organ systems including pleura, pericardium and peritoneum. Toll-like receptors (TLRs) are an essential part of the innate immune system for early recognition of pathogen-associated molecular patterns. TLRs recognise molecular pat...

Cloning, characterization and localization of CHS gene from blood orange, Citrus sinensis (L.) Osbeck cv. Ruby.
Chalcone synthase (CHS) is involved in the biosynthesis of anthocyanin. In this study, a full-length DNA of CHS gene (named as CsCHS-bo) was cloned from the blood orange, Citrus sinensis (L.) Osbeck cv. Ruby. The gene was 1,512 bp in size containing an open reading frame (1,176 bp) encoding 391 amino acids. Comparative...

Material suppliers and industrial metabolism.
Life Cycle Assessment (LCA) is not sufficiently tailored to the analysis of strategic environmental problems of material suppliers. Sustainable development calls for a reduction by a factor of 10 to 20 in the material intensity of the economy, a situation which leads to dramatic shifts in markets for raw materials. Fur...

Microbial phenol degradation of organic compounds in natural systems: Temperature-inhibition relationships.
The combined influence of high phenol concentrations and low temperatures on aerobic and anaerobic phenol degradation kinetics was investigated in microbial enrichment cultures to evaluate temperature-inhibition relationships with respect to the ambient conditions in polluted habitats. The inhibition of microbial pheno...
