Effect of Suction/Injection on Unsteady Hydromagnetic Convective Flow of Reactive Viscous Fluid between Vertical Porous Plates with Thermal Diffusion.

An investigation is performed to study the effect of suction/injection on unsteady hydromagnetic natural convection flow of viscous reactive fluid between two vertical porous plates in the presence of thermal diffusion. The partial differential equations governing the flow have been solved numerically using semi-implicit finite-difference scheme. For steady case, analytical solutions have been derived using perturbation series method.

Design, synthesis, and characterization of heparin-binding peptoids.

A series of N-substituted glycine oligomers (peptoids) of varying length and side chains was synthesized with the aim of producing peptidomimetics that would bind with high affinity to heparin and thereby neutralize its anticoagulant activity. To this end, a library of 29 peptoids was synthesized using solid phase synthesis methodologies. The general design of the peptoids was the repeating trimer sequence N(cationic side chain)-N(alkyl or benzyl side chain)-N(α-chiral side chain), where the monomers are N-substituted glycine residues bearing the indicated side chains.

Interventional pain management: a commentary.

The care of pain patients often requires a specialized knowledge base and skill set that allows the pain medicine specialist with tools necessary for optimal patient outcomes. Interventional pain medicine is the field of judiciously and appropriately applying such skills in the diagnosis and treatment of chronic pain; with the increasing prevalence of the disease, it cannot be overemphasized that providers must be equipped with the knowledge and skills to provide the care needed. This commentary provides brief, point-of-care information for providers of pain therapies in a portable, easy-to-navigate format.

Spatio-temporal characterization of the pleiotrophinergic system in mouse cerebellum: evidence for its key role during ontogenesis.

The development of the central nervous system requires an appropriate micro-environment that is conditioned by a combination of various extracellular components. Most of the known signaling factors, such as neurotransmitters or neuropeptides, are soluble and diffuse into the extracellular matrix. However, other secreted molecules like proteoglycans or glycosaminoglycans anchor in the extracellular matrix to influence cerebral ontogenesis.

Environment and mobility: a view from four discourses.

Debate and literature on the link between degrading environments and human mobility has been increasing exponentially. There is little concrete evidence, however, of efforts or policies that support the management of environmentally influenced mobility. Through discourse analysis using Q-methodology, this research aimed to scrutinize the standoff between opposing views under a fresh lens.

Tooth transposition: a descriptive study in a 547-patient sample.

Introduction: The aim of this investigation was to study the prevalence of tooth transposition in a population of orthodontic patients.

Materials And Methods: A total of 547 patient records from our dentofacial orthopedics department were consulted. Each file included clinical observations, panoramic radiography, lateral cephalograms and dental casts.

NF-κB p65 repression by the sesquiterpene lactone, Helenalin, contributes to the induction of autophagy cell death.

Background: Numerous studies have demonstrated that autophagy plays a vital role in maintaining cellular homeostasis. Interestingly, several anticancer agents were found to exert their anticancer effects by triggering autophagy. Emerging data suggest that autophagy represents a novel mechanism that can be exploited for therapeutic benefit.

Kallikrein-related peptidase signaling in colon carcinoma cells: targeting proteinase-activated receptors.

We hypothesized that kallikrein-related peptidase 14 (KLK14) is produced by colonic tumors and can promote tumorigenesis by activating proteinase-activated receptors (PARs). We found that KLK14 is expressed in human colon adenocarcinoma cells but not in adjacent cancer-free tissue; KLK14 mRNA, present in colon cancer, leads to KLK14 protein expression and secretion; and KLK14 signals viaPAR-2 in HT-29 cells to cause (1) receptor activation/internalization, (2) increases in intracellular calcium, (3) stimulation of ERK1/2/MAP kinase phosphorylation, and (4) cell proliferation. We suggest that KLK14, acting via PAR-2, represents an autocrine/paracrine regulator of colon tumorigenesis.
