We present follow-up spectroscopy of the galaxy cluster MS 1054–03 (z = 0.83) confirming that at least six of the nine merging galaxy pairs identified by van Dokkum et al. (1999) are indeed bound systems: they have projected separations of Rs < 10h −1 kpc and relative line-of sight velocities of ∆v < 165 km s. For the remaining three pairs, we were unable to obtain redshifts of both constituent...

Brassinosteroids (BRs) are plant hormones that are perceived at the cell surface by a membrane-bound receptor kinase, BRASSINOSTEROID INSENSITIVE1 (BRI1). BRI1 interacts with BRI1-ASSOCIATED RECEPTOR KINASE1 (BAK1) to initiate a signal transduction pathway in which autophosphorylation and transphosphorylation of BRI1 and BAK1, as well as phosphorylation of multiple downstream substrates, play c...

BACKGROUND Parathyroid hormone (PTH) levels are often measured after thyroid surgery and are used to detect patients at risk for postoperative hypoparathyroidism. However, there is a lack of consensus in the literature about how to define the recovery of parathyroid gland function and when to classify hypoparathyroidism as permanent. The goals of this study were to determine the incidence of lo...

OBJECTIVE Training teachers and education professionals on diabetes is crucial for full-time monitoring of diabetic children in schools. The objective of this study was to assess the knowledge on diabetes in a group of school teachers in Turkey. METHODS Between November 2010 and November 2011, 1054 teachers from three regions of Ankara were given a questionnaire to assess their knowledge on d...

The deletion of the highly conserved cytidine nucleotide at position 1054 in E. coli 16S rRNA has been characterized to confer an UGA stop codon specific suppression activity which suggested a functional participation of small subunit rRNA in translational termination. Based on this structure-function correlation we constructed the three point mutations at site 1054, changing the wild-type C re...

OBJECTIVE This study aimed to investigate the frequency of overweight and obesity among Iranian adolescent girls aged 14-17 years and its possible association with maternal education in Rasht city in 2005. DESIGN A cross-sectional survey on 1054 schoolgirls. SETTING High schools in Rasht city, Iran. METHODS A multistage sampling method was used and 1054 randomly selected schoolgirls were ...

We present a deep [O III] λλ4959,5007 image of the northern filamentary jet in the Crab Nebula taken with the 8.2-m Subaru telescope. Using this image and an image taken with the Kitt Peak National Observatory (KPNO) 4-m in 1988, we have computed proper motions for 35 locations in the jet. The results suggest that when compared to the main body of the remnant, the jet experienced less outward a...

BACKGROUND The stability of Clostridium difficile toxins is an important factor in determining the accuracy of the enzyme immunoassay (EIA). The Centers for Disease Control has stated that C. difficile toxins may become undetectable in unrefrigerated stool specimens within 2 h after collection. PURPOSE The purpose of our study was to determine how the unrefrigerated handling time of human fec...
