Two experiments were conducted to evaluate the effects of addition of sodium polyacrylate (SPA) to a phytasesupplemented diet on the performance and phosphorus (P) retention of chicks. In experiment 1, chicks were randomly allocated to four dietary treatments which were fed from 7 to 21 days of age: i) basal diet (low nonphytate phosphorus (0.23% NPP)); ii) basal with 250 U/kg diet of phytase; ...

The surface protective antigen (Spa) protein of Erysipelothrix rhusiopathiae has been shown to be highly immunogenic and is a potential candidate for a new vaccine against erysipelas. In this study, we cloned and sequenced spa genes from all E. rhusiopathiae serovar reference strains as well as from a serovar 18 strain which was not classified as any species in the genus Erysipelothrix. Sequenc...

Protein A of Staphylococcus aureus is a pathogenic factor whose encoding gene, spa, shows a variation in length in different strains. In this study the spa gene variation in S. aureus isolated from healthy carriers and patients was studied, We also compared this variation among MRSA with MSSA strains. 208 strains of Staphylococcus aureus which we were isolated from Gorgan, north of Iran were st...

Inflammatory bowel disease is frequently associated with spondylarthritis (SpA). It has been discussed that α4/β7 expressing lymphocytes are involved in the aetiology of SpA. We report a case of a successful combination therapy of vedolizumab (VDZ) and etanercept (ETA) in a patient with ulcerative colitis with pouchitis and SpA. In our case VDZ was effective for pouchitis and ineffective for Sp...

Ankylosing spondylitis is the prototype of inflammatory rheumatic diseases grouped under the term spondyloarthritis or spondyloarthropathy (SpA). New classification criteria for SpA have now been proposed; the patients are subgrouped into (1) a predominantly axial disease, termed axial SpA, which includes AS, and (2) peripheral SpA. There is an unacceptable delay in the diagnosis of axial SpA, ...

OBJECTIVE This study was performed to assess our clinical experience with single-port access (SPA) laparoscopic cystectomy and myomectomy and the surgical outcomes of those procedures at our institution. METHODS The authors evaluated the surgical outcomes of SPA laparoscopic cystectomy in 293 patients and SPA laparoscopic myomectomy in 246 patients. The surgical outcomes comprised operation t...

Staphylococcal protein A (SpA) and streptococcal protein G (SpG) affinity chromatography are the gold standards for purifying monoclonal antibodies (mAbs) in therapeutic applications. However, camelid VHH single-domain Abs (sdAbs or VHHs) are not bound by SpG and only sporadically bound by SpA. Currently, VHHs require affinity tag-based purification, which limits their therapeutic potential and...

The spa gene of Staphylococcus aureus encodes protein A and is used for typing of methicillin-resistant Staphylococcus aureus (MRSA). We used sequence typing of the spa gene repeat region to study the epidemiology of MRSA at a German university hospital. One hundred seven and 84 strains were studied during two periods of 10 and 4 months, respectively. Repeats and spa types were determined by Ri...

Interaction of staphylococcal protein A (SPA) with human serum depressed the ability of such serum to neutralize herpes simpled virus (HSV)-antibody labialis. SPA-induced depression of serum-dependent virus neutralization appeared to be due to consumption of complement by SPA. In addition, SPA attached to antibody-treated, HSV-infected cells and inhibited complement mediated immune cytolysis. T...

Physical appearance has a great importance on how people are viewed in their social environment. Many researchers in sport and exercise psychology have, therefore, applied a self-presentational approach to the study of sport and exercise behaviour (Hausenblas, Bewer & van Raalte, 2004). Since the seminal work of Hart, Leary and Rejeski (1992), researchers have examined the relationship between ...
