The mechanism that initiates human parturition has been proposed to be functional progesterone withdrawal whereby the 116-kDa B isoform of the progesterone receptor (PR-B) switches in favor of the 94-kDa A isoform (PR-A) in reproductive tissues. Recently other PR isoforms, PR-S, PR-C, and PR-M generated from the same gene have been identified and partially characterized. Using immunohistochemic...

BACKGROUND The mechanism that initiates human parturition has been proposed to be 'functional progesterone withdrawal' whereby the 116 kDa B-isoform of the progesterone receptor (PR-B) switches in favour of the 94 kDa A-isoform (PR-A) in reproductive tissues. Recently, other PR isoforms, PR-S, PR-C and PR-M generated from the same gene have been identified and partially characterised. METHODS...

Background: The aim of this study was to evaluate and compare the clinical and ‎electrocardiographic (ECG) manifestations of benzodiazepines (BZs).‎ Methods: In this retrospective study, all BZ-poisoned patients hospitalized at Loghman ‎Hakim Hospital between September 2010 and March 2011 were evaluated. Patients’ ‎information including age, sex, time elapsed between the ingestion and presenta...

pR(ST98), a chimeric plasmid isolated from Salmonella enterica serovar typhi (S. typhi), is involved in bacterial multidrug-resistance and virulence, however, its exact contributions to bacterial pathogenesis are still not fully understood. To investigate whether pR(ST98) exhibits potential to mediate macrophage autophagy and apoptosis, murine macrophage-like cell line (J774A.1) was infected wi...

Data products (macrodata or tabular data and microdat a or raw data records), are designed to inform public or bus iness policy, and research or public information. Securi ng these products against unauthorized acces ses has been a long-term goal of the database security research comm unity and the government statistical agencies. Solutions t o this problem require combining several techniques ...

We propose an elegant formulation of the Maze Routing with Bu er Insertion and Wiresizing pr oblem as a graph-the oretic shortest path problem. This formulation provides time and space performance improvements over previously proposed dynamic-programming based techniques. R outing c onstr aints such as wiring obstacles and restrictions on bu er locations and types are easily incorporated in the...

Temporal pattern learn ing, control and predict ion , and chaotic data an alysis sha re a common pr oblem : ded ucing optimal equations of motion from observations of time-dependent behavior . Each desires to obtain models of the physical world from limited information. We describe a method to reconstruct the deterministic portion of the equations of motion directly from a data series. These eq...

We explore three results related to hardness of counting. Interestingly, at their core each of these results relies on a simple — yet powerful — technique due to Valiant and Vazirani. Does SAT become any easier if we are guaranteed that the formula we are given has at most one solution? Alternately, if we are guaranteed that a given boolean formula has a unique solution does it become any easie...
