Toll-like receptors (TLRs) are pattern-recognition receptors that have a pivotal role as primary sensors of microbial products and as initiators of innate and adaptive immune responses. We investigated the role of TLR2, TLR3, and TLR4 activation during cutaneous allergen sensitization in the modulation of allergic asthma. The results show that ...

Metabolic phenotyping involves the comprehensive analysis of biological fluids or tissue samples. This analysis allows biochemical classification of a person's physiological or pathological states that relate to disease diagnosis or prognosis at the individual level and to disease risk factors at the population level. These approaches are currently being implemented ...

It has been proposed that thymosin beta 4 (TB4)-protein delivery stimulates differentiation of resident adult WT1-positive cardiac progenitor cells, but with very low efficiency. We determined whether gene therapy with human TB4 stimulates proliferation of resident adult cardiac progenitor cells in normal rat heart. Ultrasound-targeted microbubble destruction (UTMD) was used ...

Carbohelicenes generally incorporate a helical, distorted, conjugated, polyaromatic system with ortho-fused benzenoid rings, which is a fundamental molecular characteristic of this class of compounds. They have been described as "molecules in distress" due to their distortion. The generation of a chiral helicity in helicenes was observed because of a severe ...

Bendamustine, active in multiple myeloma (MM), is a bifunctional mechlorethamine derivative with alkylating properties. Bortezomib, approved to treat MM, is effective in combination with alkylators. The tolerability and efficacy of bendamustine plus bortezomib in relapsed/refractory MM was assessed in an open-label, dose-escalating, phase I/II study. Patients aged ≥18 years received intravenous ...

Genome-wide association study (GWAS) has identified serine/threonine kinase 39 (STK39) as a candidate gene for hypertension. A replication study provided supporting evidence that STK39 functional polymorphism rs35929607 was associated with hypertension. Recently, another study also showed rs6749447 within the STK39 was associated with blood pressure responses. However, these studies were ...

While the physical impact of ankylosing spondylitis (AS) is central to clinical treatment, the sexual problems associated with AS are often overlooked. Sexual problems may be related to a variety of undocumented demographic parameters, physical impairments, and psychological problems. These associations were examined through a single-center cross-sectional study of 103 ...

A transrectal prostate biopsy is the most common procedure used to establish the diagnosis of prostate cancer. Prior to biopsy, patients are commonly given ciprofloxacin for prophylaxis. However, a complication of the procedure is infection with ciprofloxacin-resistant organisms, in particular resistant Escherichia coli. In order to identify patients carrying ciprofloxacin-resistant ...
