We propose a gradient-limited affine projection algorithm (GL-APA), which can achieve fast and double-talk-robust convergence in acoustic echo cancellation. GL-APA is derived from the M-estimationbased nonlinear cost function extended for evaluating multiple error signals dealt with in the affine projection algorithm (APA). By considering the nonlinearity of the gradient, we carefully formulate...
Alternative polyadenylation (APA), in which a transcript uses one of the poly(A) sites to define its 3'-end, is a common regulatory mechanism in eukaryotic gene expression. However, the potential of APA in determining crop agronomic traits remains elusive. This study systematically tallied poly(A) sites of 14 different rice tissues and developmental stages using the poly(A) tag sequencing (PAT-...
Aminopeptidase A (APA) cleaves angiotensin (Ang) II, kallidin, and other related peptides. In the brain, it activates the renin angiotensin system and causes hypertension. Limited data are available on the dipsogenic effect of APA and pressor effect of degraded peptides of APA such as bradykinin. Wistar-Kyoto rats received intracerebroventricular (icv) APA in a conscious, unrestrained state aft...
Alternative polyadenylation (APA) can for example occur when a protein-coding gene has several polyadenylation (polyA) signals in its last exon, resulting in messenger RNAs (mRNAs) with different 3' untranslated region (UTR) lengths. Different 3'UTR lengths can give different microRNA (miRNA) regulation such that shortened transcripts have increased expression. The APA process is part of human ...
Local concentrations of the vasopressor peptide, angiotensin II (AngII), depend upon the balance between synthesis and degradation. Previous studies of blood pressure (BP) regulation have focused primarily on the generation of AngII and its receptors, and less attention has been devoted to angiotensin degradation. Aminopeptidase A (APA, EC 3.4.11.7) is responsible for the N-terminal cleavage of...
CONTEXT Antipituitary antibodies (APA) are frequently present in patients with autoimmune polyendocrine syndrome (APS). DESIGN The aim was to evaluate the predictive value of APA for the occurrence of hypopituitarism. A total of 149 APA-positive and 50 APA-negative patients with APS and normal pituitary function were longitudinally studied for 5 yr. METHODS APA, by indirect immunofluorescen...
OBJECTIVE The occurrence of antipituitary antibodies (APA) in patients with idiopathic hyperprolactinaemia (IH) and the effects of dopamine agonists on these antibodies and long-term pituitary function outcome have been so far not evaluated. This longitudinal study was aimed at investigating, in patients with IH the occurrence of APA and the effect of cabergoline on the pituitary function and b...
The role of antipituitary antibodies (APA) in autoimmune pituitary diseases still needs to be clarified. The aim of this study was 2-fold: first, to investigate the presence of APA in adults with idiopathic or acquired GH deficiency (GHD) and in adults with autoimmune endocrine diseases; and second, to evaluate whether in autoimmune endocrine patients APA titer is correlated to the pituitary fu...
دائره المعارف شرح حال اندیشمندان اسلامی شامل 300 مدخل است که توسط 38 مؤلف و با ویراستاری الیور لیمن[1] تدوین شده است. این مجموعه نخستین بار در سال 2006 با جلد گالینگور در دو مجلد توسط انتشارات بلومبزبری[2] در لندن و نیویورک منتشر شده است. سپس در سال 2015 با جلد شومیز و به صورت تک جلدی در 500 صفحه تجدید چاپ شده که در این چاپ برخی از اشتباهات چاپ نخست تصحیح شده و عنوان برخی از مدخل ها نیز به عنوا...
