[KIDNEY DISEASES IN NORTH ISRAEL ACCORDING TO KIDNEY BIOPSIES - BNAI-ZION MEDICAL CENTER 14 YEARS' EXPERIENCE].

Introduction: Little is known about the prevalence of kidney diseases according to renal biopsy in Israel. Since updated literature worldwide emphasizes changing etiologies of chronic kidney disease, it is crucial to research and define the epidemiology and pathology of kidney disease in Israel. Hereby, we introduce an original review of the prevalence of kidney diseases in our study population, which we believe reflects the prevalence of kidney diseases in the population of Israel.

Increased aortic wall thickness for the diagnosis of aortitis: a computed tomography-based study.

Aims: To evaluate the usefulness of computed tomography (CT)-measured aortic wall thickness (AWT) as a sole imaging finding for the confirmation of clinically suspected aortitis.

Methods: CT scans of 20 patients with the diagnosis of aortitis, endorsed by the abnormally thickened aortic wall, as a single imaging finding, and 250 patients without known aortitis were reviewed and AWT manually measured at the levels of thoracic descending aorta, upper abdominal aorta and infrarenal aorta, as well as the level of maximal AWT in patients with diagnosed aortitis. Patients' charts were analyzed and demographic data and data on co-morbidities extracted.

Clk post-transcriptional control denoises circadian transcription both temporally and spatially.

The transcription factor CLOCK (CLK) is essential for the development and maintenance of circadian rhythms in Drosophila. However, little is known about how CLK levels are controlled. Here we show that Clk mRNA is strongly regulated post-transcriptionally through its 3' UTR.

Self-regulation and internal resources in school-aged children with ADHD symptomatology: an investigation using the Rorschach inkblot method.

This study assesses the capacity for emotional self-regulation and internal resources in a sample of urban children with ADHD symptomatology using the Rorschach Inkblot Method (RIM). Because these children have profound difficulty with modulating their affect, it is hypothesized that this difficulty would be reflected on RIM variables that have traditionally been thought to reflect the internal resources necessary for these children to regulate emotions. Children with greater ADHD symptoms were found to display lower scores on variables indicating internal resources for emotional self-regulation and stress tolerance (M, EA) relative to a comparison group with fewer ADHD symptoms.

Concordance rates between parent and teacher clinical evaluation of language fundamentals observational rating scale.

Background: Research has shown that early identification of children with language issues is critical for effective intervention, and yet many children are not identified until school age. The use of parent-completed rating scales, especially in urban, minority populations, might improve early identification if parent ratings are found to be reliable and valid.

Aims: To evaluate the reliability and validity of the Observational Rating Scale (ORS) in an urban setting where it may be difficult to distinguish language difficulties from cultural language differences.

Is there a selective relationship between language functioning and auditory attention in children?

This study explores the selectivity of the relationship between auditory attention and language in children. A total of 42 children (16 females) between 7.0 and 10.

The puzzle of acupuncture.

Acupuncture is based on the theory of channels, which serve as pathways for energy (Qi). On the course of the channels, acupuncture points are described, and by stimulation of these points, therapeutic effects may be achieved. This system is very complex and both channels and acupuncture points are anatomically invisible.

Pulsatile venous insufficiency in severe tricuspid regurgitation: does pulsatility protect against complications of venous disease?

Prior observations showed that the consequences of venous hypertension depend not only on the magnitude of the venous pressure but also on the efficiency of compensatory mechanisms that protect against the effects of excessive pressures on the microcirculation. Pulsatile venous insufficiency (PVI) associated with severe tricuspid regurgitation (TR) provides the opportunity to investigate the effect of the pulsatile shear stress on the outcome of venous insufficiency. The authors conducted a study to assess the flow characteristics and clinical outcome of PVI associated with TR.

Does acupuncture treatment affect sperm density in males with very low sperm count? A pilot study.

Classic therapies are usually ineffective in the treatment of patients with very poor sperm density. The aim of this study was to determine the effect of acupuncture on these males. Semen samples of 20 patients with a history of azoospermia were examined by light microscope (LM) and scanning electron microscope (SEM), with which a microsearch for spermatozoa was carried out.

Effect of acupuncture on sperm parameters of males suffering from subfertility related to low sperm quality.

The aim of this prospective controlled study was to assess the effect of acupuncture on the sperm quality of males suffering from subfertility related to sperm impairment. Semen samples of 16 acupuncture-treated subfertile patients were analyzed before and 1 month after treatment (twice a week for 5 weeks). In parallel, semen samples of 16 control untreated subfertile males were examined.

The impact of falls in an inner-city elderly African-American population.

Objective: To describe the impact of falls in an elderly African-American urban community and to identify predictors of poor recovery from falls.

Design: Prospective cohort study.

Setting: Emergency departments of 11 hospitals in western Philadelphia.

Ultrasound investigation of fetal human upper respiratory anatomy.

Although the human upper respiratory-upper digestive tract is an area of vital importance, relatively little is known about either the structural or functional changes that occur in the region during the fetal period. While investigations in our laboratory have begun to chart these changes through the use of postmortem materials, in vivo studies have been rarely attempted. This study combines ultrasonography with new applications of video editing to examine aspects of prenatal upper respiratory development.

Genome structure of Tetrahymena pyriformis.

Reassociation kinetics of DNA from the macronucleus of the ciliate, Tetrahymena pyriformis GL, has been studied. The genome size determined by the kinetic complexity of DNA was found to be 2.0 X 10(8) base pairs (or 1.

[Distribution of repeating nucleotide sequences in the macronucleus DNA of Tetrahymena infusoria].

The genome of Tetrahymena pyriformis macronucleus contain less than 10% of repetitive sequences. About half of them consist of long, more than 2000 base pairs, moderately repeated sequences. Short repetitive sequences (200--300 base pairs) represent 4--5% of the genome.
