Evidence is presented that the 2 50 A thick chromosome fiber consists of clusters of nucleosomes (superbeads) which are heterogeneous in size. In bovine lymphocyte chromatin their number average corresponds to about 12 nucleosomes.
The WT-V129_1 asymmetric unit contains one PrP molecule, exhibiting the conserved PrP fold. The C-terminal helix 3 is 3D-domain swapped with a second molecule related by crystallographic two-fold symmetry (Figure 1A), resulting in a dimer covalently-linked by disulfide bonds that is nearly identical to the WT-M129 structure (Knaus et al, 2001). A threonine-rich hinge loop (T190-F198) precedes h...
OBJECTIVE To examine maternal and obstetric factors influencing births by cesarean section according to health care funding. METHODS A cross-sectional study with data from Southeastern Brazil. Caesarean section births from February 2011 to July 2012 were included.

BACKGROUND New approaches are needed to bolster the modest effects of campus drinking prevention programs. However, more definitive research on new paradigms is very expensive, and in the current economic climate, progress can be made by evaluating smaller pilot studies. This study describes one such approach. METHODS A sample of 18-year-old or older, healthy, drinking freshmen at our univers...
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
For genome-wide expression studies data handling is important since global effects in the same direction on many genes can skew the results. The standard method recommended by Affymetrix is MAS5. We have not used this method but rather RMA which normalize the data on probe level and not on gene level and will accordingly in theory be less prone to normalize away global effects. It is important ...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
this study explored reading strategy use of tefl ma students when they read academic research articles in english. the purpose of this study was to investigate how this group of readers typically approaches reading academic research articles related to their field of study, and also what they do in reading such research articles. the aim of the present study was bilateral. first, the researcher...
the purpose of this study was to investigate how english language teachers in mashhad who teach students in the pre-university cycle perceived the impact of the efltee on their teaching. the target population was nearly all pre-university english language teachers in seven districts of mashhad in the scholastic year 2008/2009. a survey questionnaire which consisted of (36) likert type items, wa...
abstract lexical knowledge of complex english words is an important part of language skills and crucial for fluent language use (nation, 2001). the present study, thus, was an attempt to assess the role of morphological decomposition awareness as a vocabulary learning strategy on learners’ productive and receptive recall and recognition of complex english words. so 90 sophomores (female and ma...
