Background Triggering Receptor Expressed on Myeloid Cells 2 (TREM2) and Apolipoprotein E (ApoE) are two of the strongest genetic risk factors for late-onset Alzheimer’s disease (AD), but while their interplay in microglial response to AD pathology is hotly studied, surprisingly little known about mechanism by which variants impair this role. Method To define structural AD-associated TREM2-ApoE ...

To determine the influence of the method of administration of a pharmaceutical formulation we have examined the importance of application volume and area in the absorption of phenol red, as a model drug, from the rat-liver surface. When 1 mg phenol red was applied to the rat-liver surface, in-vivo, in three volumes (0.1, 0.2 or 0.334 mL) using a cylindrical glass cell (i.d. 9 mm), the shape of ...

In comparison to the previous researches, ZrO2 nanoparticles with higher surface area (85 m2/g) have been synthesized in this research. The as-prepared ZrO2 nanoparticles by co-precipitation method were characterized with X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). The surface area of the s...

The importance of computational chemistry in modern scientific research is well established. Continuous improvement in software and algorithms for the modeling of chemical interactions has transformed molecular modeling into a powerful tool for many current day research projects. From a medical perspective, one of the ultimate goals in computer-aided drug design (CADD) is the accurate predictio...

Auxin/IAA (Indole-3-acetic acid) plays critical roles in many aspects of plant growth and development. Gretchen Hagen 3.1 (GH3.1) enzyme from grapevine (Vitis vinifera) catalyzes the ATP-dependent conjugation of aspartate to IAA suggesting a significant way to modulate levels of cellular auxins/IAA. It is reported that VvGH3.1 prefers IAA as the substrate than 1-naphthaleneacetic acid (NAA) and...

A model for ionic solutions with an attractive short-range pair interaction between the ions is presented. The short-range interaction is accounted for by adding a quadratic nonlocal term to the Poisson-Boltzmann free energy. The model is used to study solvent effects in a planar electric double layer. The counterion density is found to increase near the charged surface, as compared with the Po...

Ion and voltage dependencies of sodium-calcium exchange current were studied in giant membrane patches from guinea pig ventricular cells after deregulation of the exchanger with chymotrypsin. (a) Under zero-trans conditions, the half-maximum concentration (Kh) of cytoplasmic calcium (Cai) for activation of the isolated inward exchange current decreased as the extracellular sodium (Nao) concentr...

PURPOSE This study evaluated the depth of cure of resin composite cured by light through a translucent fiber post. MATERIALS AND METHODS The opaque plastic tubes in various lengths of 2, 4, 6, 8, 10, 12, 14 mm. were filled with resin composite in which two different translucent fiber posts were inserted into the center and photo-polymerized for 40 seconds. The degree of conversion of the cure...
