salmonella enterica serovar typhimurium and s.enterica serovar enteritidis are the most frequently isolated serovars from food-borne diseases throughout the world. according to their antigenic profiles, salmonella shows different disease syndromes and host specificities. it is necessary and important to discriminate salmonella serovars from each other in order to ensure that each pathogen and i...

The growth and appearance of 115 stock Salmonella isolates on a new formulation of CHROMagar Salmonella (CAS) medium were compared to those on xylose-lysine-desoxycholate agar (XLD), Salmonella-Shigella agar (SS), and Hektoen enteric agar (HEA) media. CAS medium was then compared prospectively to XLD and SS for the detection and presumptive identification of Salmonella strains in 500 consecutiv...

OBJECTIVE The Das-Naglieri Cognitive Assessment System (CAS) is a test of cognitive abilities based on the Planning, Attention, Simultaneous, and Successive Theory (PASS). Studies of CAS performance by children with ADHD typically show lowest performance on Planning and deficits on Attention, but normal Simultaneous and Successive processing. Such distinct group differences studies support cons...

various techniques and culture media were developed for rapid identification of salmonella serovars. however, there are still problems with their sensitivity and specificity. in an attempt to reduce the time spent to obtain a result and to minimize the problems associated with rapid detection systems such as interference from food ingredients debris, micro flora in feces, and lack of sensitivit...

Les sacro-iliites infectieuses méritent d'être mieux connues. Leur diagnostic est souvent retardé en raison d'une symptomatologie trompeuse et des diffcultés d'exploration de l'articulation sacro-iliaque. Notre travail est basé sur une étude rétrospective portant sur les cas de SII, recueillis sur une période comprise entre 1997 et 2008 dans notre centre universitaire Sfax-Tunisie. Le diagnosti...

CHROMagar Salmonella (CAS), a new chromogenic medium, was retrospectively compared to Hektoen enteric agar (HEA) with 501 Salmonella stock isolates and was then prospectively compared to HEA for the detection and presumptive identification of Salmonella spp. with 508 stool samples before and after enrichment. All stock cultures (100%), including cultures of H2S-negative isolates, yielded typica...

Objective: A case that developed unilateral posterior reversible encephalopathy syndrome (PRES) after carotid artery stenting (CAS) is reported. Case Presentation: The patient was a 79-year-old man who underwent CAS for symptomatic right internal carotid artery stenosis. Left hemiparesis and unilateral spatial neglect appeared on the day after the procedure. MRI presented findings characteristi...

Cyanoacrylates (CAs) were not widely adopted for medical use until recently because of lingering concerns regarding the initial tissue toxicities of the short-chain CAs. The medium-chain CAs, primarily butyl-cyanoacrylate, have been widely used in Europe and Canada for several decades and have gone a long way in dispelling any lingering concerns about tissue toxicity. The newer, longer chain CA...

Background and purpose - The long-term effects of computer-assisted surgery in total knee replacement (CAS) compared to conventionally operated knee replacement (CON) are still not clear. We compared survivorship and relative risk of revision in CAS and CON based on data from the Norwegian Arthroplasty Register. Patients and methods - We assessed primary total knee replacements without patellar...

Many concurrent data-structure implementations use the well-known compare-and-swap (CAS) operation, supported in hardware by most modern multiprocessor architectures, for inter-thread synchronization. A key weakness of the CAS operation is the degradation in its performance in the presence of memory contention. In this work we study the following question: can software-based contention manageme...
