Objective(s): An increase in nitric oxide (NO) production has been reported in cirrhotic cardiomyopathy and, portal hypertension. Since minocycline has been shown to inhibit NO overproduction, we aimed to examine its role in a rat model of CCl4-induced cirrhotic cardiovascular complications. Materials and Methods: Portal pressure and inotropic responsiveness of isolated papillary muscles to is...

umbilical and supraumbilical catheter insertion is a common procedure performed in the nicu. it is a safe and usually easy procedure devoid of serious mishaps, morbidity and mortality. complications such as hemorrhage, infection, hernia, evisceration, omphalitis, portal vein thrombosis and portal hypertension may occur after umbilical catheter insertion. other uncommon and rare complications re...

An experimental investigation into the influence of Brownian motion on shear-induced particle migration of monodisperse suspensions of micrometre-sized colloidal particles is presented. The suspension is pumped through a 50 μm× 500 μm rectangular crosssection glass channel. The experiments are characterized chiefly by the sample volume fraction (φ=0.1− 0.4), and the flow rate expressed as the P...

mmWave communication systems overcome high attenuation by using multiple antennas at both the transmitter and the receiver to perform beamforming. Upon entrance of a user equipment (UE) into a cell a scanning procedure must be performed by the base station in order to find the UE, in what is known as initial access (IA) procedure. In this paper we start from the observation that UEs are more li...

The goal of this study was to document the dynamic effects created within, and the developing mechanisms of a gunshot entrance wound to the skin utilizing high-speed photography and the "skin-skull-brain model". The high-speed photography was taken with an Imacon 468/Hadland-Photonics camera. Full metal jacketed, 9 mm Luger projectiles were fired at the target model from a distance of 10 m. Dur...

The behaviour of the nestlings of nocturnal cavity-nesting species has relatively rarely been studied in detail because of problems connected with use of the technical devices required to provide long-term monitoring of individuals. However, long-term observation of nestling behaviour is crucial in order to identify different types of behaviour which may be caused by sibling competition at the ...

The RESTART method is a widely applicable simulation technique for the estimation of rare event probabilities. The method is based on the idea to restart the simulation at certain intermediate stages, in order to generate more occurrences of the rare event. In many cases we are interested in the (rare) event that a real-valued function of some Markov process exceeds a high level. We explore the...

In this paper we take a formal look at the nature of the re-entrance problem. We see the essence of the problem in a conflict between the assumptions components make about each other’s behavior. We argue that to ensure safe composability of mutually dependent components in an open system one needs to reason about them modularly. We propose an approach for extending component specifications with...

Selective permeability in voltage-gated Ca 2 1 channels is dependent upon a quartet of pore-localized glutamate residues (EEEE locus). The EEEE locus is widely believed to comprise the sole high-affinity Ca 2 1 binding site in the pore, which represents an overturning of earlier models that had postulated two high-affinity Ca 2 1 binding sites. The current view is based on site-directed mutagen...
