background: low back pain is the most common cause of disability and absence from work among young and middle-aged people. as there is limited knowledge regarding this problem among iranian students, this study aimed to determine the preva­lence of low back pain and its ‘related socio­demo­graphic factors among students of islamic azad university, tehran, iran.    material and methods: this is ...

Oxidative stress-induced damage, including 8-oxo-guanine and apurinic/apyrimidinic (AP) DNA lesions, were detected in dormant and outgrowing Bacillus subtilis spores lacking the AP endonucleases Nfo and ExoA. Spores of the Δnfo exoA strain exhibited slightly slowed germination and greatly slowed outgrowth that drastically slowed the spores' return to vegetative growth. A null mutation in the di...

The disA gene encodes a putative amino acid decarboxylase that inhibits swarming in Proteus mirabilis. 5' rapid amplification of cDNA ends (RACE) and deletion analysis were used to identify the disA promoter. The use of a disA-lacZ fusion indicated that FlhD(4)C(2), the class I flagellar master regulator, did not have a role in disA regulation. The putative product of DisA, phenethylamine, was ...

In response to DNA damage, cells activate checkpoint signaling cascades to control cell-cycle progression and elicit DNA repair in order to maintain genomic integrity. The sensing and repair of lesions is critical for Bacillus subtilis cells entering the developmental process of sporulation as damaged DNA may prevent the cells from completing spore morphogenesis. We report the identification of...

The purpose of this research brief is to review and describe the most rele‐ vant and recent data on the topic of sport participation rates among Amer‐ ican youth by various historically underserved populations. Specifically, data is aggregated and summarized by social class, race, gender, and disa‐ bility status. While the available data and research related to sport partici‐ pation and physica...

This article focuses on a psycho-educational programme, DISA, currently practiced in the Swedish schools to prevent girls from developing depressive symptoms. We draw on group interviews with schoolgirls to explore how they describe DISA and how an understanding of the programme is constructed through their arguments. We demonstrate how the girls’ version of DISA highlights a contradiction in t...

The aim of this study was to investigate the effectiveness of the DISA-programme in preventing depressive symptoms (DS) in adolescent girls, as implemented in a real-world school setting, accounting for baseline socioeconomic and psychosocial factors, and to investigate whether the effects of these baseline variables on DS differed between intervention participants and non-participants. In this...

OBJECTIVE To analyze the trend of the monthly "caesarean section rate" (CSR) at the DISA V Lima-Ciudad Hospitals during the period 2001 - 2008. MATERIAL AND METHODS Ecological study that aim to analyze the monthly reports of all DISA V Lima-Ciudad Hospitals that attends childbirths, and by analyzing the trend of theirs monthly caesarean section ratio or monthly CSR (TCM = total caesarean birt...

The photophysics of a prospective drug molecule, 3,5-diiodosalicylic acid (3,5-DISA), having a wide spectrum of biological and medicinal applications, have been investigated using spectroscopic techniques and computational analyses. The remarkably large Stokes' shifts in various solvents from 3,5-DISA has been intertwined with the occurrence of an excited-state intramolecular proton transfer (E...
