Vinylidene chloride (VDC) is a groundwater and drinking water contaminant. Monochloroacetic acid (MCA) is a chlorination by-product of drinking water. Because environmental or occupational exposure to chemicals takes place at low concentrations, a sensitive in vitro system of liver slices was used to examine the interactive toxicity of MCA and VDC. Liver slices from Sprague-Dawley rats were exp...

BACKGROUND AND PURPOSE Knowledge of the topographic distribution of infarcts of the middle cerebral artery (MCA) may give insight into the limits of the arterial territory and infarct mechanism and may influence the decision to use thrombolytic therapy. We describe the creation of a digital atlas of MCA (DA-MCA) infarction associated with MCA branch and trunk occlusion using magnetic resonance ...

OBJECTIVES To establish reference ranges for middle cerebral artery peak systolic velocity (MCA PSV) and to certify their value in the management of Rhesus alloimmunized pregnancies. MATERIAL AND METHODS A reference range of MCA PSV with gestation was constructed by studying 342 pregnancies at 25-40 weeks. A comparison was made between the reference ranges produced in our study and those alre...

Maurocalcine (MCa), initially identified from a Tunisian scorpion venom, defines a new member of the family of cell penetrating peptides by its ability to efficiently cross the plasma membrane. The initiating mechanistic step required for the cell translocation of a cell penetrating peptide implicates its binding onto cell surface components such as membrane lipids and/or heparan sulfate proteo...

BACKGROUND Medication reviews have become part of pharmacy practice across developed countries. This study aimed to identify factors affecting the likelihood of eligible Ontario seniors receiving a pharmacy-led medication review called MedsCheck annual (MCA). METHODS We designed a cohort study using a random sample of pharmacy claims for MCA-eligible Ontario seniors using linked administrativ...

Hemodynamic changes can be noninvasively real-time monitored in stroke patients by means of transcranial Doppler sonography (TCD). The aim of this pilot study was to assess hemodynamic changes in both middle cerebral arteries (MCA) in aphasic stroke patients by means of TCD during verbal stimulation. Eight aphasic patients with stroke in the territory of the left MCA were tested by modified Bos...

BACKGROUND Our aim was to compare different thresholds of middle cerebral artery peak systolic velocity (MCA-PSV) and amniotic fluid delta optical density (Delta-OD) with fetal hemoglobin (Hb) during first and second intrauterine transfusions (IUT). METHODS We determined serial MCA-PSV and Delta-OD in 27 red blood cell alloimmunized fetuses who needed IUT. Before the second IUT, MCA-PSV was m...

La clase de los carbonatos está representada en el Catálogo Referencia del Mueso Mineralogía la UAEH por 78 fichas que van MCA-01 a MCA-78.

BACKGROUND AND PURPOSE Transcranial color-coded real-time sonography (TCCS) is a useful tool to evaluate disease of the middle cerebral artery (MCA). This study was undertaken to identify TCCS criteria for the diagnosis of MCA stem and MCA branch occlusions. METHODS TCCS and digital subtraction angiography were performed in 55 consecutive patients with acute stroke: 10 with MCA stem occlusion...
