The aim of our study was to evaluate the middle cerebral artery velocimetry before and after intrauterine blood transfusion in immune hydrops fetalis. The current study was conducted in a tertiary research hospital, from February 2009 to January 2011. Nineteen intrauterine blood transfusions performed during the study period. The factors recorded were age of the mothers, gestational weeks, pre-...

OBJECTIVE The goal of this research was to develop a screening instrument for early identification among hospitalized children of medical child abuse (MCA). METHODS We developed a preliminary screening instrument for the early identification of MCA. Items were chosen based on published characteristics of MCA, including caregiver, patient, and illness information. Each item in the instrument w...

BACKGROUND AND PURPOSE The purpose of the present study was to evaluate availability of transcranial color-coded real-time sonography (TCCS) to detect hyperperfusion after carotid endarterectomy (CEA). METHODS This prospective study included 105 consecutive patients who underwent CEA for severe carotid stenosis. TCCS with echo contrast agents was performed serially to evaluate flow velocity o...

We determined whether human lung fibroblasts (HLFs) might release mediators that are responsible for monocyte chemokinetic activity (MCA) constitutively. HLF supernatant fluids showed MCA in a time-dependent manner ( P < 0.001). Checkerboard analysis of 24- and 72-h supernatant fluids showed that the activity was chemokinetic. Partial characterization of 24- and 72-h supernatant fluids revealed...

BACKGROUND AND PURPOSE Previous studies suggest that dynamic autoregulation in the posterior cerebral artery (PCA) is less efficient compared to the middle cerebral artery (MCA). We examined the role of cerebral vasodilation caused by metabolic activation (ie, visual stimulus) on autoregulatory characteristics in the 2 vascular territories. METHODS Blood flow velocity in the PCA and MCA and m...

BACKGROUND AND PURPOSE The index of mean blood flow velocity (V) in the middle cerebral artery (MCA) divided by respective velocity in the ipsilateral internal carotid artery (ICA), or V(MCA)/V(ICA) index, is commonly used as a marker of vasospasm, although reference values are not established. We sought to provide reference data for these velocities and index. METHODS Transcranial color-code...

To clarify the effect of surgery on the prevention cerebral hemorrhage in adult moyamoya disease, we compared postoperative courses between superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis and conservative therapy. The study subjects were 30 adults with moyamoya disease. Unilateral STA-MCA anastomosis was conducted in 7 of these 30 cases, and bilateral STA-MCA anastomosi...

In a business-to-business (B2B) environment, most if not every large company interacts with suppliers, customers, and competitors on one or more Net markets, connecting to both ends of the supply chain, the supplier side and the customer side. To support purchasing agents, analysts, and managers in evaluating their purchasing decisions, a new analytical tool is presented, the Marketplace Compet...

Maurocalcine (MCa) is a 33-amino-acid residue peptide toxin isolated from the scorpion Scorpio maurus palmatus. External application of MCa to cultured myotubes is known to produce Ca2+ release from intracellular stores. MCa binds directly to the skeletal muscle isoform of the ryanodine receptor, an intracellular channel target of the endoplasmic reticulum, and induces long lasting channel open...

BACKGROUND AND PURPOSE Patterns and mechanisms of stroke in patients with atherosclerotic middle cerebral artery (MCA) disease remain unclear. We sought to identify lesion patterns and stroke mechanisms associated with MCA disease using early diffusion-weighted imaging (DWI). METHODS We reviewed 185 acute ischemic stroke patients who had (1) symptomatic lesions located in the unilateral MCA t...
