Identification of T=0 and T=1 Bands in the N=Z=37 Nucleus 74Rb

The gamma decay of excited states in the N = Z odd-odd nucleus Rb-74 has been observed for the first time. The reaction Ca-40(Ca-40,alpha pn)Rb-74 at 128 MeV beam energy was used. The ground state rotational band can be interpreted as being formed from the T = 1 isobaric analog states of Kr-74 with pairing correlations based on T = 1, M(T) = 0 neutron-proton pairs. At higher rotational frequency,

Cortical auditory event-related potentials in newborn infants.

The possibility of recording changes in electroencephalography potentials following perception of sound was reported several decades ago. The recent expanding research on auditory cortical event-retated potentials (AERPs) for assessing sound discrimination abilities in children and infants has indicated that several methodological issues need to be addressed before it can be implemented in clinica

Visualization of the drop deformation and break-up process in a high pressure homogenizer

For the creation of sub-micron emulsions in fluids of low viscosity the high pressure homogenizer (HPH) is usually chosen. One way of obtaining deeper knowledge of exactly what happens in the active region is to visualize it. In this work, a drop deformation and break-up visualization system based on a modified Particle Image Velocimetry (PIV) system is described. The system reproduces the gap in

Intrinsically proton-conducting benzimidazole units tethered to polysiloxanes

Polysiloxanes with pendant benzimidazole units have been prepared by free radical thiolene coupling reactions of 2-(2-benzimidazolyl)ethanethiol and vinyl-functional polysiloxanes. The latter polymers were prepared by anionic ring opening copolymerization of 1,3,5,7-tetramethyl-1,3,5,7-tetravinylcyclosiloxane and 1,3,5-hexamethyleyclosiloxane. Copolymers with different degrees of benzimidazole fun

Mitogenomic analyses place the gharial (Gavialis gangeticus) on the crocodile tree and provide Pre-K/T divergence times for most crocodilians

Based on morphological analyses, extant members of the order Crocodylia are divided into three families, Alligatoridae, Crocodylidae, and Gavialidae. Gavialidae includes one species, the gharial, Gavialis gangeticus. In this study we have examined crocodilian relationships in phylogenetic analyses of seven mitochondrial genomes that have been sequenced in their entirety. The analyses did not suppo

Correlations and chaotic motion in nuclear masses

Correlations of the difference between the measured and calculated mass of neighbouring nuclei obtained from different nuclear compilations are studied. The autocorrelation function is found to be, to a good approximation, model independent. The result is well described by a semiclassical theory that assumes the existence of a contribution to the nuclear mass associated with a chaotic motion of th

Performance of density functionals for first row transition metal systems

This article investigates the performance of five commonly used density functionals, B3LYP, BP86, PBE0, PBE, and BLYP, for studying diatomic molecules consisting of a first row transition metal bonded to H, F, Cl, Br, N, C, O, or S. Results have been compared with experiment wherever possible. Open-shell configurations are found more often in the order PBE0 > B3LYP > PBE similar to BP86 > BLYP. Ho

Coronary flow velocity reserve reduction is comparable in patients with erectile dysfunction and in patients with impaired fasting glucose or well-regulated diabetes mellitus

Background There is growing evidence that erectile dysfunction is a sentinel for future coronary artery disease. Recently published studies have shown signs of impaired coronary endothelial function in patients with erectile dysfunction, without clinical cardiovascular disease and diabetes. We evaluated the magnitude of coronary vasodilatory dysfunction in men with erectile dysfunction, as compare

Neuroprotection in the rat Parkinson model by intrastriatal GDNF gene transfer using a lentiviral vector.

We used a recombinant lentiviral vector (rLV) for gene delivery of GDNF to the striatum, and assessed its neuroprotective effects in the intrastriatal 6-hydroxydopamine (6-OHDA) lesion model.The level of GDNF expression obtained with the rLV-GDNF vector was dose-related and ranged between 0.9-9.3 ng/mg tissue in the transduced striatum, as determined by ELISA, and 0.2-3.0 ng/mg tissue were detecte

Expression profiling to predict outcome in breast cancer: the influence of sample selection

Gene expression profiling of tumors using DNA microarrays is a promising method for predicting prognosis and treatment response in cancer patients. It was recently reported that expression profiles of sporadic breast cancers could be used to predict disease recurrence better than currently available clinical and histopathological prognostic factors. Having observed an overlap in those data between

Health-related quality of life in secondary progressive multiple sclerosis

Common disability scales in multiple sclerosis (MS) are often weighted towards physical disability. Non-motor symptoms such as depression, fatigue and pain substantially influence wellbeing in MS. Health-related quality of life (HRQoL) measures the broader impact of MS and might indicate less obvious disease burdens. We analysed HRQoL, using the Nottingham Health Profile Part I (NHP-I), among 345

pUB2380: characterization of a ColD-like resistance plasmid

A detailed analysis of the mobilizable, ColE1-like resistance plasmid, pUB2380, is reported. The 8.5-kb genome encodes six (possibly seven) major functions: (1) a ColD-like origin of replication, oriV, with associated replication functions, RNAI and RNAII; (2) a set of active mobilization functions highly homologous to that of ColE1, including the origin of transfer, oriT; (3) a ColE1-like multime

Endoscopic surveillance of columnar-lined esophagus - Frequency of intestinal metaplasia detection and impact of antireflux surgery

Objective To quantify the occurrence of intestinal metaplasia in columnar-lined esophagus (CLE) during endoscopic surveillance and to evaluate the impact of antireflux surgery on the development of intestinal metaplasia. Summary Background Data The malignant potential in segments of CLE is mainly restricted to those containing intestinal metaplasia. Patients with segments of CLE in which no intest

Transcranial Doppler pulsatility index is not a reliable indicator of intracranial pressure in children with severe traumatic brain injury

Background: The TCD-derived PI has been associated with ICP in adult studies but has not been well investigated in children. We examined the relationship between PI and ICP and CPP in children with severe TBI. Methods: Data were prospectively collected from consecutive TCD studies in children with severe TBI undergoing ICP monitoring. Ipsilateral ICP and CPP values were examined with Spearman corr
