BACKGROUND Streptococcus mutans surface-protein antigen (SpaP, PAc, or antigen I/II) has been well known to play an important role in initial attachment to tooth surfaces. However, strains with weak SpaP-expression were recently reported to be found in natural populations of S. mutans. The S. mutans gbpC-negative strain Z1, which we previously isolated from saliva and plaque samples, apparently...
BACKGROUND In the pulmonary circulation, there is a linear relationship between systolic pulmonary arterial pressure (SPAP) and mean pulmonary arterial pressure (MPAP). The aim of this study was to determine the passive or active nature of this mechanism by exploring the relationship in patients with and without autonomic rhythm control of the heart and pulmonary circulation. METHODS Pulmonar...
Lung cancer represents a major health problem. Cytostatic and radiotherapeutic treatment is limited because of dose-limiting systemic toxicity and surgery as a result of its invasive nature. Therefore, we developed a catheterization model of selective pulmonary artery perfusion (SPAP) combining the properties of isolated lung perfusion and i.v. treatment to achieve higher local drug levels and ...
Serum is used as an additive in the preparation of human spermatozoa for fertilization in vitro, as it is superior to other body fluids in supporting sperm motility. We recently purified the major sperm activating macromolecule present in serum and showed it to be a complex of immunoglobulin and apolipoprotein A-I. This complex, which we named sperm activating protein (SPAP), has now been furth...
BACKGROUND Schistosomiasis-associated pulmonary arterial hypertension (SPAH) is a major concern worldwide. However, the role of gender-specific contributing factors in SPAH is unknown. OBJECTIVE We investigated how systolic pulmonary artery pressure (SPAP) values and the presence of severe SPAP relate to gender, menopausal status, and pregnancy history in SPAH patients. METHODS Seventy-nine...
در بخش1.1 این رساله با الهام از اصل ایده¬آلهای اول، اصل زیرمدول¬های اول معرفی شده و با استفاده از آن تعدادی از قضایای بالا در نظریه مدول¬ها بیان شده¬اند. در ]42[، لَم و رایس سوالی در مورد خانواده¬های قویاً اوکا مطرح کرده¬اند که در فصل دوم نشان داده¬ایم جواب این سوال برای حلقه¬ها¬ی spap، مثبت است. در بخش 2.2، با بررسی خواص حلقه¬ها¬ی spap ، نشان داده شده کلاس حلقه¬ها¬ی spap در شرایط خاص زیرکلاسی از...
In this paper we focus on a special class of commutative local rings called SPAP-rings and study the relationship between this class and other classes of rings. We characterize the structure of modules and especially, the prime submodules of free modules over an SPAP-ring and derive some basic properties. Then we answer the question of Lam and Reyes about strongly Oka ideals fam...
OBJECTIVE Exercise systolic pulmonary arterial pressure (SPAP) predicts the occurrence of symptoms in patients with degenerative mitral regurgitation (MR). However, this measurement is not always available. The purpose of this study was to identify resting echocardiographic predictors of exercise SPAP and whether predicted exercise SPAP may predict symptom-free survival. METHODS We prospectiv...
Background. Pulmonary arterial hypertension (PAH) is the main cause of morbimortality in systemic sclerosis (SSc). Increased Eng expression has been demonstrated in SSc patients. Objective. Ascertaining serum levels of Eng in SSc patients with and without elevated systolic pulmonary arterial pressure (sPAP) and comparing them with that of healthy volunteers. Methods. A cross-sectional study was...
OBJECTIVE The aim of this study was to assess the prognostic value of systolic pulmonary artery pressure (sPAP) estimated by echocardiography in the multinational European League Against Rheumatism Scleroderma Trial and Research (EUSTAR) cohort. METHODS Data for patients with echocardiography documented between 1 January 2005 and 31 December 2011 were extracted from the EUSTAR database. Stepw...
