Active control of ion transport plays important roles in chemical and biological analytical processes. Nanofluidic systems hold the promise for such control through electrostatic interaction between ions and channel surfaces. Most existing experiments rely on planar geometry where the nanochannels are generally very long and shallow with large aspect ratios. ...

The subtype-B monomers of the human immunodeficiency virus type-1 (HIV-1) have experimentally been shown to dimerize at high salt concentration or in the presence of magnesium, while the dimerization of the subtype-A monomers requires magnesium binding at the G(273) or G(274) phosphate groups regardless of salt concentration. We used explicit ...

Yersinia pestis protein Pla is a plasmid-coded outer membrane protein with aspartic-protease activity. Pla exhibits a plasminogen (Plg) activator activity (PAA) that promotes the cleavage of Plg to the active serine-protease form called plasmin. Exactly how Pla activates Plg into plasmin remains unclear. To investigate this event, we performed the ...

Adipose tissue engineering aims to grow fat tissue for soft tissue reconstruction after tumour resection or trauma. However, insufficient progenitor cell differentiation and poor vascularization compromise the generation of clinically applicable adipose tissue. The desired process of neo-adipogenesis seems to be difficult to mimic, even though it takes place in ...

Systemic immune activation is increased in HIV-infected individuals, even in the setting of virus suppression with antiretroviral therapy. Although numerous factors may contribute, microbial products have recently emerged as potential drivers of this immune activation. In this Review, we describe the intestinal damage that occurs in HIV infection, the evidence ...

A growing body of research is demonstrating increased accuracy in aging from a relatively new method, transition analysis. Although transition analysis was developed for paleodemographic research, a majority of subsequent studies have been in the forensic arena, with very little work in bioarchaeological contexts. Using the Suchey-Brooks pubic symphysis phases, ...

Spider venom is a large pharmacological repertoire containing many biologically active peptides, which may have a potent therapeutic implication. Here we investigated a peptide toxin, named lycosin-I, isolated from the venom of the spider Lycosa Singorensis. In contrast to most spider peptide toxins adopting inhibitor cystine knot (ICK) motif, lycosin-I ...

The telomerase-specific replication-competent oncolytic adenovirus, Telomelysin, was developed for virus-mediated preferential lysis of tumor cells. Its selectivity is derived from a human telomerase reverse transcriptase (hTERT) promoter-driven active viral replication, which occurs in cancer cells with high telomerase activity but not in normal cells lacking such activity. Since the TERT ...

Rhodium and iridium complexes bearing a tridentate [PEP] type ligand ([PEP] = {o-(Ph(2)P)C(6)H(4)}(2)E(Me); E = Ge or Sn) were synthesized through the phosphine exchange reaction accompanied by selective E-C bond cleavage. The ligand precursors {o-(Ph(2)P)C(6)H(4)}(2)EMe(2) (E = Ge or Sn) were readily obtained in excellent yields by treating {o-(Ph(2)P)C(6)H(4)}(2)Li with ...

Abstract The health service sector has a vital role to play in delivering human immunodeficiency virus (HIV) and tuberculosis (TB) prevention, treatment and care, yet evidence indicates that healthcare workers (HCWs) themselves lack adequate access to HIV and TB services. HCWs are also at increased risk from TB and other ...

A tomography approach is used to reconstruct 3D cell shapes and, simultaneously, the shapes/positions of the nuclei within these cells. Subjecting the cells to well-defined microconfinements of various diameters allow for relating the steady-state shapes of cells to their static-mechanical properties. The observed shapes show striking regularities between different cell ...

The compendial method of evaluation of orodispersible tablets (ODT) is the same disintegration test as for conventional tablets. Since it does not reflect the disintegration process in the oral cavity, alternative methods are proposed that are more related to in vivo conditions, e.g. modified dissolution paddle apparatus, texture analyzer, rotating ...

Abstract Membrane-bound pyrophosphatases (M-PPases) are enzymes that enhance the survival of plants, protozoans and prokaryotes in energy constraining stress conditions. These proteins use pyrophosphate, a waste product of cellular metabolism, as an energy source for sodium or proton pumping. To study the structure and function of these enzymes we have ...

Abstract Protein kinase C (PKC) activation induced by diacylglycerols (DAGs) is one of the sequels of the dysregulation of intramuscular lipid metabolism and is thought to play an important role in the development of insulin resistance (IR). We tested the hypothesis that DAGs with different acyl chains have different biological ...

BACKGROUND: The imbalance between pro-inflammatory and anti-inflammatory cytokines may possibly play a role in the development of bronchopulmonary dysplasia (BPD) in preterm infants. Mannose binding lectin (MBL) codon 54 and interleukin 1 receptor antagonist gene (IL1-RN) polymorphisms cause genetic predisposition to increased risk of infection and inflammation, therefore may increase ...

Cancer drugs that target pivotal signaling molecules required for malignant cell survival and growth have demonstrated striking antitumor activities in appropriately selected patient populations. Unfortunately, however, therapeutic responses are often of limited duration, typically 6-12 months, due to emergence of drug-resistant subclones of tumor cells. In this review, we highlight ...

Schwann cell motility was observed on laminin-coated quartz cylinders with different curvatures over an 18 hour period. A new analysis based on difference images helped to determine the minimal radius of curvature, 46 μm, which restricted motility along the cylinder axis. The migration speed, measured by calculating differences between successive ...

In eukaryotes, dolichols (C(70-120) ) play indispensable roles as glycosyl carrier lipids in the biosynthesis of glycoproteins on endoplasmic reticulum (ER). In addition to dolichols, seed plants have other types of Z,E-mixed polyisoprenoids termed ficaprenol (tri-trans,poly-cis-polyprenol, C(45-75) ) and betulaprenol (di-trans,poly-cis-polyprenol, C(30-45) and C(≥70) ) in abundance. However, the physiological ...

Three innovative assays are developed for the detection of enzymatic activities of glucose oxidase (GOx) and horseradish peroxidase (HRP) by the generation of CdS quantum dots (QDs) in situ using non-conventional enzymatic reactions. In the first assay, GOx catalyzes the oxidation of 1-thio-β-D-glucose to give 1-thio-β-D-gluconic acid. The latter is ...

Once coal is excavated it comes into contact with atmospheric oxygen and begins to undergo low temperature oxidation. The mechanism by which the molecular oxygen interacts with the coal macromolecule is suggested to occur in several steps. These steps primarily involve O(2) diffusion to the surface where physical adsorption followed ...
