Given a prime power q and an integer n ? 2 , we establish sufficient condition for the existence of primitive pair ( ? f ) where ? F x is rational function degree sum . (Here = 1 / are coprime polynomials respectively, their degrees + .) For any such guaranteed to exist sufficiently large Indeed, when definitely does not only 28 values possibly (but unlikely) at most 3911 other

Several new HLA-B locus alleles have been discovered in South American Amerindians. By contrast, analysis of the MHC class I alleles of North American native populations has revealed few new HLA-B alleles. This suggests that the HLA-B locus is evolving rapidly in South American populations. Here we describe the HLA-B locus alleles present in individuals from a Central American tribe, the Kuna o...

Abstract Background and Aims High oxalic acid concentration may be caused by genetic disorders, enteric diseases, but also kidney insufficiency per se. It result in stones, function decline, failure. This study aimed to investigate whether dietary intake influences plasma a population undergoing transplantation. Method Dietary was assessed using Food Frequency Questionnaire. Based on frequency ...

This study examines medical conditions diagnosed prior to the diagnosis of autism spectrum disorder (ASD). Using a matched case control design with 3911 ASD cases and 38,609 controls, we found that 38 out of 79 medical conditions were associated with increased ASD risk. Developmental delay, mental health, and neurology conditions had the strongest associations (ORs 2.0-23.3). Moderately strong ...

Although the relationship between religion and science has long been subject of discussion, investigations into how why people's science-religion perspectives are rare. This study examined epistemic ontological cognition predict agreement with four perspectives: conflict, independence, dialogue, integration. Participants (N = 3911) were Finnish, Danish, Dutch adults who had answered an online s...

Benzene is the emblematic example of an aromatic molecule, and the problem of its structure has given rise to a chemical serial story running over several decades. The epistemological digest of this story written by Stephen G. Brush1,2 shows how this problem has been at the root of important concepts such as those of mesomery and resonance. Before the advent of quantum mechanics, chemists had t...

– OBJECTIVE: MicroRNAs (miRNAs) act as key regulators of diverse cellular activities by regulating the expression of proteincoding genes. Osteoblast differentiation, a fundamental step in skeletal development, involves the activation of several signaling pathways, including transforming growth factor β (TGF-β), bone morphogenetic protein (BMP), and Wnt signaling pathways. MATERIALS AND METHODS:...

The dynamics of long terminal repeat (LTR) retrotransposons and their contribution to genome evolution during plant speciation have remained largely unanswered. Here, we perform a genome-wide comparison of all eight Oryza AA-genome species, and identify 3911 intact LTR retrotransposons classified into 790 families. The top 44 most abundant LTR retrotransposon families show patterns of rapid and...
