The Multidimensional Model of Racial Identity was used to examine the relationship between racial identity and personal self-esteem (PSE) in a sample of African American college students (n = 173) and a sample of African American high school students (n = 72). Racial identity was assessed using the Centrality and Regard scales of the Multidimensional Inventory of Black Identity, whereas the Ros...

Background. Both splenectomy (SP) and partial splenic embolization (PSE) are used to treat massive splenomegaly (MSM) secondary to hepatitis B-related liver cirrhosis (HB-LC). This retrospective case-control study was conducted to compare the effects of SP and PSE on these patients. Methods. From July 2004 to January 2012, patients with MSM secondary to HB-LC who underwent SP or PSE were 1 : 1 ...

Pale, soft, and exudative (PSE) pork is primarily caused by an accelerated rate of postmortem glycolysis resulting in low muscle pH while carcass temperature remains high, thus causing protein denaturation. Numerous factors influence the rate of postmortem metabolism and may be responsible for the rapid pH decline characteristic of PSE pork during the 1st h postmortem. Release of high levels of...

expression of eukaryotic proteins in e. coli often results in their aggregation. proper folding and solubility of therapeutical proteins are the pre-requisite for their bioactivity. this is not achieved in cytoplasmic expression in e. coli because of the absence of disulfide bonds formation. a novel expression/secretion vector was constructed which exploited β-lactamase signal sequence to trans...

BACKGROUND Prolonged slow expiration (PSE) is a physiotherapy technique often applied in infants to reduce pulmonary obstruction and clear secretions, but there have been few studies of PSE's effects on the respiratory system. OBJECTIVE To describe PSE's effects on respiratory mechanics in infants. METHODS We conducted a cross-sectional study with 18 infants who had histories of recurrent ...

Some Legionella strains possess a strong extracellular proline-specific endopeptidase (PSE) activity. Using an enlarged selection of chromogenic peptides representing a variety of N-terminal amino-acids binding to a -prolyl-proline, paranitroanilide chain, PSE activity of Legionella and Flavobacterium strains was examined. Differences in PSE activity emphasized the importance of the chemical st...

The role of the Internet is about to change again. After the hype of web portals we look forward to an Internet in which networked services dominate. Already today we can find services on the Internet in a large number of different categories: communication, on-line shopping, entertainment, enterprise services to mention only a few. However, problems with the currently prevailing infrastructure...

In trypanosomatids, the spliced leader RNA, or SL RNA, donates its 5' 39 nucleotides to mature nuclear mRNAs in a process termed trans-splicing. We have previously characterized the SL RNA gene from Trypanosoma cruzi and identified its transcription promoter, including a 14 nt proximal sequence element, or PSE, that binds a putative transcription factor and activates transcription of the gene. ...
