Extracellular phosphate is toxic to the cell at high concentrations. When the phosphate level is increased in the blood by impaired urinary phosphate excretion, premature aging ensues. When the phosphate level is increased in the urine by dietary phosphate overload, this may lead to kidney damage (tubular injury and interstitial fibrosis). Extracellular phosphate exerts its cytotoxicity when it...
Cationic CPPs (cell-penetrating peptides) have been used largely for intracellular delivery of low-molecular-mass drugs, biomolecules and particles. Most cationic CPPs bind to cell-associated glycosaminoglycans and are internalized by endocytosis, although the detailed mechanisms involved remain controversial. Sequestration and degradation in endocytic vesicles severely limits the efficiency of...
Cell-penetrating peptides (CPPs) are short sequences of amino acids that facilitate the penetration of conjugated cargoes across mammalian cell membranes, and as such, they may provide a safe and effective method for drug delivery to the inner ear. Simple polyarginine peptides have been shown to induce significantly higher cell penetration rates among CPPs. Herein, we show that a peptide consis...
Tapered metallic grooves have been shown to support plasmons - electromagnetically coupled oscillations of free electrons at metal-dielectric interfaces - across a variety of configurations and V-like profiles. Such plasmons may be divided into two categories: gap-surface plasmons (GSPs) that are confined laterally between the tapered groove sidewalls and propagate either along the groove axis ...
Casein phosphopeptides (CPPs) containing chelated calcium drastically increase the secretion of extracellular homologous and heterologous proteins in filamentous fungi. Casein phosphopeptides released by digestion of alpha - and beta-casein are rich in phosphoserine residues (SerP). They stimulate enzyme secretion in the gastrointestinal tract and enhance the immune response in mammals, and are...
PURPOSE Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) exhibits variable lower urinary tract symptoms (LUTS). The aim of this study was to evaluate the incidence of LUTS and the efficacy of an anticholinergic agent in young and middle-aged CP/CPPS patients. METHODS Ninety-six men with CP/CPPS were randomly assigned in a single-blind fashion and received either ciprofloxacin (group...
Introduction: The Nef accessory protein is an attractive antigenic candidate in the development of HIV-1 DNA- or protein-based vaccines. The most crucial disadvantage of DNA and protein-based vaccines is their low immunogenicity, which can be improved by cell-penetrating peptides (CPPs) as effective carrier molecules. Methods: In this study, the HIV-1 Nef protein was generated in the Escherichi...
INTRODUCTION This article reviews the rationale and data supporting alpha blocker therapy for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), the most common and difficult prostatitis syndrome. METHODS Systematic review identified ten clinical trials evaluating alpha blocker therapy for patients with CP/CPPS, including five open-label or small prospective studies and five double-b...
In this research, several intelligent strategies have been developed to build up cooperative Process Planning and Scheduling (CPPS). Three game theory-based strategies have been introduced to analyse the cooperative integration of the two processes in a systematic way. To address the multiple constraints in the CPPS problem, a fuzzy logic-based Analytical Hierarchical Process (AHP) technique ha...
Nanoparticles, such as semiconductor quantum dots (QDs), have been found increasing use in biomedical diagnosis and therapeutics because of their unique properties, including quantum confinement, surface plasmon resonance, and superparamagnetism. Cell-penetrating peptides (CPPs) represent an efficient mechanism to overcome plasma membrane barriers and deliver biologically active molecules into ...
