Interactions within a protein structure and interactions between proteins in an assembly are essential considerations in understanding molecular basis of stability and functions of proteins and their complexes. There are several weak and strong interactions that render stability to a protein structure or an assembly. Protein Interactions Calculator (PIC) is a server which, given the coordinate ...

Double-stranded RNA (dsRNA)-dependent protein kinase (PKR) is an interferon-induced protein kinase that plays a central role in the anti-viral process. Due to its pro-apoptotic and anti-proliferative action, there is an increased interest in PKR modulation as an anti-tumor strategy. PKR is overexpressed in breast cancer cells; however, the role of PKR in breast cancer cells is unclear. The expr...

BACKGROUND Changes in choroidal circulation hemodynamics during the course of punctate inner choroidopathy (PIC) remain unknown. The aim of this study was to quantitatively evaluate changes in choroidal blood flow velocity by using laser speckle flowgraphy (LSFG) in patients with PIC. CASE PRESENTATION This PIC patient was initially treated with systemic corticosteroids for 4 months. LSFG mea...

OBJECTIVES To characterise the clinical features, emergency pre-paediatric intensive care (PIC) treatment, and course of status epilepticus (SE) in children admitted to PIC. This may provide insight into reasons for admission to PIC and provide a framework for the development of strategies that decrease the requirement for intensive care. DESIGN Cross sectional, retrospective study. SETTING...

Chromium picolinate [Cr(pic)(3)] is a nutritional supplement widely promoted to exert beneficial metabolic effects in patients with type 2 diabetes/impaired glucose tolerance. Frequent comorbidities in these individuals include systemic hypertension, abnormal vascular function and ischemic heart disease, but information on the effects of the supplement on these aspects is sparse. Utilizing male...

PURPOSE This study sought to identify and characterize subtypes of alpha 2-adrenoceptors in rabbit ciliary body. METHODS Radioligand binding assays were performed with the alpha 2-agonist ligand [125I]-p-iodoclonidine ([125I]PIC) and the antagonist ligand [3H]rauwolscine. RESULTS Both [125I]PIC and [3H]rauwolscine bound to a single population of receptors in membrane preparations of rabbit ...

This paper presents a personal computer (PC)-based data acquisition and control tool that uses a Peripheral Interface Controller (PIC) microcontroller, Matlab, and Simulink. Specifically, a library of PIC microcontroller functions for Simulink is created. Moreover, the PIC microcontroller and Matlab are merged, by exploiting their serial communication capability, to produce an inexpensive data ...
