R is called commuting regular ring (resp. semigroup) if for each x,y $in$ R there exists a $in$ R such that xy = yxayx. In this paper, we introduce the concept of commuting $pi$-regular rings (resp. semigroups) and study various properties of them.
چکیده سابقه و هدف: فنوتیپ بالا بودن همزمان دور کمر و تریگلیسیرید سرم که به عنوان یک ابزار تشخیصی چاقی احشایی پیشنهاد داده شده و نیز محصول تجمع لیپید، یک شاخص ساده و گویا برای تجمع بیش از حد چربی در بالغین است. فیتوکمیکالها ترکیبات زیستفعال غیرمغذی هستند که به وفور در میوهها، سبزیها، غلات، مغزها و حبوبات یافت میشوند. هدف مطالعهی ما، تعیین نقش امتیاز شاخص فیتوکمیکال (PI) در بروز فنوتیپ "با...
OBJECTIVES The aim of the study was to investigate ultrasound and Doppler parameters in the third trimester of pregnancy as possible predictors of adverse perinatal outcome in unselected pregnancies. MATERIAL AND METHODS We performed a retrospective cross-sectional study including unselected pregnant women be-tween 27 and 36 + 6 weeks of gestation. The following ultrasound and Doppler paramet...
مقدمه: ترومای سر سومین علت مرگ و از شایعترین علتهای مراجعه به اورژانس است. تعیین پیشآگهی در این بیماران باعث تشخیص افراد در معرض خطر بالاتر و ارائه رسیدگی سریعتر و کاملتر به آنان میشود؛ لذا اهمیت ویژهای دارد(2). از پایشهای مورد استفاده، بررسی فشار داخل مغز و چگونگی توزیع خونرسانی بافت مغز با استفاده ازداپلر ترانس کرانیال(TCD) است. هدف: تعیین پیشآگهی بیماران با ترومای متوسط سر با استفاد...
(ABSTRACT) Recent studies suggest that lymphocyte apoptosis serves to regulate pulmonary inflammation. Equine COPD, an allergic disease of the lower airway, is likely due to dysregulation of the pulmonary immune response. In this study, the hypothesis tested was COPD affected horses would have less apoptotic airway lymphocytes than control horses during clinical disease. To achieve this, 3 meth...
INTRODUCTION Transrectal rectal ultrasound (TRUS)-guided systematic biopsy is the gold standard for diagnosis of prostate cancer. However, systematic biopsy has high false-negative rate and often misses anteriorly located tumors. Magnetic resonance imaging (MRI)-TRUS fusion biopsy can potentially improve cancer detection by better visualization and targeting of cancer focus. We evaluated the ro...
We have investigated the hypothesis that different contractile agonists activate distinct catalytic subunits of phosphoinositide (PI) 3-kinase in smooth muscle cells. Endothelin (10-7 M) induced a sustained increase in PI 3-kinase activity at both 30 s and 4 min of stimulation (151.5 ± 8.5% at 30 s and 175.8 ± 8.7% at 4 min, P < 0.005). Preincubation of smooth muscle cells with the tyrosine kin...
Recent studies have shown that dietary phospholipids, especially phosphatidylcholine and phosphatidylserine, have various beneficial biological effects. However, there are not enough data concerning the physiological function of dietary phosphatidylinositol (PI). The metabolic syndrome, a cluster of metabolic abnormalities such as dyslipidemia, diabetes mellitus, and hypertension, is widespread...
A characterization of the humoral immune response of alpacas to Fasciola hepatica Fas1 and Fas2 antigens cysteine proteinases was performed over the course of 6 months of experimental infection. Six adult alpacas aged 1 to 2 years old received a single dose of 200 F. hepatica metacercariae, 2 non–infected alpacas were kept as control group. Peripheral eosinophilia in infected animals was greatl...
Dietary arachidonic acid (AA) has roles in growth, neuronal development, and cognitive function in infants. AA is remarkably enriched in phosphatidylinositol (PI), an important constituent of biological membranes in mammals; however, the physiological significance of AA-containing PI remains unknown. In an RNA interference-based genetic screen using Caenorhabditis elegans, we recently cloned mb...
