زمینه و هدف : استناد را می توان یکی از پایه های اصلی تدوین کارهای علمی و پژوهشی مکتوب به شمار آورد، که هر محققی در مدلل کردن یافته های علمی خود، ناگزیر بدین شیوه روی می آورد. حفظ و تداوم پیوند اطلاعاتی از طریق استناد، به شرط صحت آن ضروری به نظر می رسد. این مطالعه با هدف بررسی وضعیت صحت مقالات استنادی و میزان مطابقت آنها با شیوه نامه ونکوور در پایان نامه های سال 1386 دوره های دکترای تخصصی پزشک...
Post-transcription mRNA processing in the 3'-untranslated region (UTR) of transcripts alters mRNA landscape. Alternative polyadenylation (APA) utilization in the 3'-UTR often leads to shorter 3'-UTR affecting mRNA stability, a process that is regulated by PABPN1. In skeletal muscles PABPN1 levels reduce with age and a greater decrease in found in Oculopharyngeal muscular dystrophy (OPMD). OPMD ...
It is accepted that the role of Anticipatory Postural Adjustments (APA) during gait initiation is to create the propulsive forces necessary to reach the gait velocity at the end of the first step. The aim of this study was to examine whether and how an overload modifies these APA. Twenty-one subjects performed gait initiation in two experimental conditions: unloaded (UL) and with an overload of...
Alternative poly(A) site choice (also known as alternative polyadenylation, or APA) has the potential to affect gene expression in qualitative and quantitative ways. APA may affect as many as 82% of all expressed genes in a plant. The consequences of APA include the generation of transcripts with differing 3'-UTRs (and thus differing regulatory potential) and of transcripts with differing prote...
Adrenal aldosterone-producing adenoma (APA), producing the salt-retaining hormone aldosterone, commonly causes secondary hypertension, which often persists after unilateral adrenalectomy. Although persistent hypertension was correlated with residual hormone aldosterone, the in vivo mechanism remains unclear. NADPH oxidase is the critical cause of aldosterone synthesis in vitro. Nox2 and p22phox...
Anticipatory postural adjustments (APA) during bimanual actions can be observed when participants hold an object in one hand and then lift it with the other hand. The postural force used to hold the object is reduced in anticipation of unloading, indicating an accurate prediction of the change in load. We examined patients with unilateral or bilateral cerebellar damage as well as two individual...
OBJECTIVE After unilateral adrenalectomy (uADX) in patients with a unilateral aldosterone-producing adenoma (APA), the remaining contralateral adrenal gland is generally considered sufficient to support life. However, few studies have compared adrenal reserve function before and after uADX. Therefore, we closely evaluated adrenal cortisol secretory function before and after uADX in patients wit...
A significant proportion of patients with Essential Thrombocythaemia (ET) have thrombotic complications which have an important impact upon the quality, and duration of their life. We performed a retrospective cross sectional study of the prevalence of antiphospholipid antibodies (APA) in 68 ET patients. Compared to 200 "elderly" controls (>50 years) there was a significant increase in anticard...
Alkaline phosphatase activity (APA) is an indicator of phosphorus status in marine plants. We examined APA in the symbiotic dinoflagellate Symbiodinium bermudense, which occurs with the sea anemone Aiptasia pallida. We have developed an assay for APA that serves as a biological indicator of inorganic phosphate (Pi) exposure in coral reef environments and phosphorus deficiency in zooxanthellae. ...
