Studies were performed to determine the regulation of DMT1 (divalent metal transporter 1) during RA (retinoic acid)-induced differentiation of P19 embryonic carcinoma cells. Protein and mRNA expression for the +/-IRE (iron response element) forms of DMT1, but not the 1A isoform, were down-regulated within the first few hours upon removal of RA, at which time the cells began to differentiate. Th...

There are several known ways of storing stack data structure – as a linked list (called list from now on in this paper), an array which size is dynamically increased on demand (called vector), or a doubleended queue (called deque). C++ Standard [1] suggests a deque as a standard container to use as a back-end for a stack's internal storage. C++ deque implementations should rely on memory paging...

PURPOSE To study whether the Artifact Removal procedure available for eliminating artifacts in multifocal electroretinograms (mERG) works correctly or not. METHODS A test response was made using a photo-diode circuit. mERGs were recorded from 3 well-trained normal subjects using the Veris III system, and were then analyzed by the procedure that is included in the Veris Science (Artifact Remov...

Sudden pipe expansions have been known as efficient hydraulic energy dissipaters for a long time. The complex phenomenon of flow separation and velocity discontinuity at the interface of incoming jet and the recirculation flow, results in intensive shear and tensile rupture of the fluid and the associated destructive phenomenon of cavitation. This paper focuses on aeration in sudden pipe expans...

background the early repolarization pattern (erp) has been considered a normal variant in electrocardiography (ecg) for a long time. nevertheless, increasing evidence has demonstrated its association with adverse outcomes. objectives the present study aimed to evaluate the prevalence of erp in the iranian general population and demonstrate its clinical and ecg correlates. methods a cross sectio...
