Application of protoplast transformation and single- and double-crossover mutagenesis protocols to alkaliphilic Bacillus firmus OF4811M (an auxotrophic strain of B. firmus OF4) facilitated the extension of the sequence of the previously cloned nhaC gene, which encodes an Na+/H+ antiporter, and the surrounding region. The nhaC gene is part of a likely 2-gene operon encompassing nhaC and a small ...

The structure of the unbound F15 nucleus is investigated using inverse kinematics resonant scattering a radioactive O14 beam impinging on CH2 target. analysis H1(O14,p)O14 and H1(O14,2p)N13 reactions allowed confirmation previously observed narrow 1/2? resonance, near two-proton decay threshold, identification two new 5/2? 3/2? resonances. newly levels by 1p emission to ground O14, sequential 2...

AIM To determine possible nerve conduction changes in the somatosensory pathway in children with brain ventricular dilatation and to estimate the relation between the ventricular size and somatosensory evoked potentials (SEP). METHODS Twelve children with ventricular dilatation (frontal and occipital horn ratios >0.44) and 19 children without ventricular dilatation (control group), aged betwe...

In a field trial conducted with eight varieties in the north coast area of Natal ratoon stunting disease (RSD) caused increasing lossesin yieldsof cane and sucrosefrom the plant to the second ratoon crop. All the varieties suffered losses in yield but the degree of loss differed markedly among the varieties. The total yield of sugar from the three crops was reduced by 38% in varieties NCo 376an...

in the recent years, the coherence index is used in many electroencephalographic studies for investigation of brain connectivity in children with adhd disorder. it is suggested that the coherence is a useful index in discrimination of adhd subjects from normal subjects. however, a few studies are accomplished in subtypes of adhd to identify of differences in functional connectivity between adhd...

objective: the aim of this study was to examine the differences between adhd subtypes in executive function tasks compared to themselves and normal controls. method: in this study, 45 school aged children with attention deficit hyperactivity disorder (adhd) and 30 normal children who were matched based on age and iq score in wechsler intelligence scale for children-revised (wisc-r) were compare...

Preliminary investigations in South Africa into determining the resistance of sugarcane varieties to red rot (Glomerella tucumanensis) by means of an inoculation procedure, conducted in 1988-89, showed promise. Results of these trials, together with findings from industry-wide red rot surveys in the late 1980s, were used to provide a preliminary ranking of a number of released varieties. Variet...

Introduction: Contrary to Diagnostic and Statistical Manual of Mental Disorders (DSM-5), fifth edition, some studies indicate that ADHD-inattentive presentation (ADHD-I) is a distinct diagnostic disorder and not an ADHD presentation.  Methods: In this study, 12 ADHD-combined presentation (ADHD-C), 10 ADHD-I, and 13 controls were enrolled and their resting state EEG recorded. Following thi...

background: there have been several studies conducted on the relationship between bipolar mood disorder and attention deficit hyperactivity disorder ( adhd) during the recent years, and in most of them the rate of this association had been estimated as 22-90% and had been reported as noticeable. the goal of this study is to determine the prevalence of adhd in patients with bipolar mood disorder...
