Continuous brain-function monitoring: State of the art in clinical practice.

Continuous electroencephalographic (EEG) monitoring gives direct information on brain function in newborn infants needing intensive care. To improve the possibilities of long-term monitoring, the EEG is time-compressed and recorded with a reduced number of electrodes. A trend measure of the EEG, the amptitude-integrated EEG (aEEG), has proved capable of giving relevant information in newborn infan

A rare blood group: p phenotype. A rare blood group is usually defined as the absence of a high prevalence antigen or the absence of several antigens within a single blood group system. These individuals may develop clinically significant red cell antibodies to the high incidence red cell antigens they lack. A 33-year-old alloimmunized woman was referred to our center at the 12th week of her third

New release cell for NMR microimaging of tablets Swelling and erosion of poly(ethylene oxide)

A small release cell, in the form of a rotating disc, has been constructed to fit into the MRI equipment. The present work show that both qualitative and quantitative information of the swelling and erosion behavior of hydrophilic extended release (ER) matrix tablets may be obtained using this release cell and non-invasive magnetic resonance imaging (MRI) studies at different time-points during ma

Survivor path processing in Viterbi decoders using register exchange and traceforward

This paper proposes a new class of hybrid VLSI architectures for survivor path processing to be used in Viterbi decoders. The architecture combines the benefits of register exchange and trace-forward algorithms, that is, low memory requirement and latency versus implementation efficiency. Based on a structural comparison, it becomes evident that the architecture can be efficiently applied to codes

Chiral hexarhodium clusters containing heterobidentate phosphine ligands, a structural and reactivity study

Some intrinsically chiral [Rh6(CO)14(µ,2-PX)] clusters have been synthesized, beginning with reactions of [Rh6(CO)16–x(NCMe)x](x= 1, 2) with PX, where PX represents the bidentate bridging ligands diphenyl(benzothienyl)phosphine (1), diphenyl(2-thienyl)phosphine (2), di(2-thienyl)phenylphosphine (3), tris(2-thienyl)phosphine (4), diphenyl(2-pyridyl)phosphine (5) and diphenylvinylphosphine (6). The

Identification of mecA-related oxacillin resistance in staphylococci by the E test and the broth microdilution method

A set of 165 strains of different staphylococcal species, 67 Staphylococcus aureus, 71 novobiocin-sensitive coagulase-negative staphylococci (CNS) and 27 novobiocin-resistant CNS was used. The oxacillin and methicillin MICs were recorded after 24 and 42 h of incubation at 35 degrees C and at 30 degrees C. Significantly higher MICs were recorded at 30 degrees C compared with 35 degrees C. While a p

The association between changes in skin echogenicity and the fibroblast production of biglycan and versican in systemic sclerosis

Objective To investigate a possible association between the longitudinal changes in skin involvement and the fibroblast production of proteoglycans in vitro, among patients with early and untreated systemic sclerosis (SSc). Methods In 11 patients, 6 with diffuse cutaneous systemic sclerosis (dSSc) and 5 with limited cutaneous systemic sclerosis (lSSc), and in 6 controls skin thickness and skin ech

Long-term results of stenting for chronic iliac artery occlusion.

PURPOSE: To evaluate the long-term results of stent placement for chronic occlusions of the iliac arteries. METHODS: Between October 1992 and December 1997, 73 patients (40 men; median age 64 years, range 42-89) with 76 occluded iliac arteries (33 common, 34 external, and 9 both vessels) were treated with percutaneous recanalization and stenting using a variety of self-expanding and balloon-expand

Aquaporins and water homeostasis in plants

Aquaporins are water channel proteins of vacuolar and plasma membranes. When opened they facilitate the passive movement of water molecules down a water potential gradient. In Arabidopsis, 30 genes have been found that code for aquaporin homologues. Some of these genes code for highly abundant constitutively expressed proteins and some are known to be temporally and spatially regulated during deve

VPAC2-R Mediates the Lipolytic Effects of Pituitary Adenylate Cyclase-Activating Polypeptide/Vasoactive Intestinal Polypeptide in Primary Rat Adipocytes.

The neuropeptides pituitary adenylate cyclase-activating polypeptide (PACAP) and vasoactive intestinal polypeptide (VIP) are structurally and functionally related. Their actions have been shown to be mediated by three different receptor subtypes: PAC1-R, which has exclusive affinity for PACAP, and VPAC1-R and VPAC2-R, which have equal affinity for PACAP and VIP. We recently showed that PACAP38 ind

An integrated simulation model of the Euro50

The Euro50 is a proposed optical telescope with an equivalent aperture of 50 m. It will have a segmented primary mirror and full adaptive optics. To study the interaction of the telescope structure, the control system and the optics, an integrated simulation model has been formulated. The mechanical model is a modal version of an Ansys finite element model. The optics model is based on ray tracing

The first record of Odontopleura ovata (Trilobita) from Scandinavia: part of a middle Silurian intercontinental shelly benthos mass occurrence

We report here, for the first time, the occurrence of the trilobite Odontopleura (Odontopleura) ovata Emmrich, 1839 from Scandinavia. The specimens came in light during a study of middle Silurian calcareous mudstone formed in offshore settings of the Baltic Basin (Grotlingbo-1 core, south-eastern Gotland). Intrabasinal correlation shows that the taxon had a brief mass occurrence during the latest

Structure of Proton-Conducting Alkali Thio-Hydroxogermanates

Using it combination Of neutron diffraction, infrared spectroscopy. and first-principles calculations, we have investigated the structure of hydrated and dehydrated proton conducting alkali thio-hydroxogermanates of general formula M2GeS2(OH)(2)center dot yH(2)O (M = K, Rb, and Cs). The results show that the structure of hydrated and dry materials are basically the same, which confirms previous in

Heterologous expression of barley and wheat oxalate oxidase in an E-coli trxB gor double mutant

Oxalate oxidase catalyses the degradation of oxalic acid to carbon dioxide and hydrogen peroxide and is of commercial importance for clinical analyses of oxalate in biological samples. Novel potential applications for oxalate oxidase include the prevention of the formation of calcium oxalate incrusts in pulp and paper manufacture and rapid determination of oxalic acid in process waters. The potent

Fe-57 Mossbauer effect study of bannisterite: a modulated 2 : 1-type phyllosilicate

Bannisterite is a modulated 2:1-type phyllosilicate having ten octahedral sites with hydroxyl groups in trans, cis and combined trans-cis configurations. Each octahedral site, depending on its proximity to the layer modulation, is exposed to a different degree of distortion. The electric field gradient at the Fe site and the site distortion are used to propose a model for the site assignment and o
