Multilocus patterns of nucleotide variability and the demographic and selection history of drosophila melanogaster populations [PDF]

open access: yes, 2005
Uncertainty about the demographic history of populations can hamper genome-wide scans for selection based on population genetic models. To obtain a portrait of the effects of demographic history on genome variability patterns in Drosophila melanogaster ...

Transmembrane serine protease 2 Polymorphisms and Susceptibility to Severe Acute Respiratory Syndrome Coronavirus Type 2 Infection: A German Case-Control Study

open access: yesFrontiers in Genetics, 2021
The transmembrane serine protease 2 (TMPRSS2) is the major host protease that enables entry of the severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) into host cells by spike (S) protein priming.

Syntax for free: representing syntax with binding using parametricity [PDF]

open access: yes, 2009
We show that, in a parametric model of polymorphism, the type ∀ α. ((α → α) → α) → (α → α → α) → α is isomorphic to closed de Bruijn terms. That is, the type of closed higher-order abstract syntax terms is isomorphic to a concrete representation.

Analysis of polymorphism in the survivin gene promoter as a potential risk factor for head and neck cancers development [PDF]

open access: yesSrpski Arhiv za Celokupno Lekarstvo, 2013
Introduction. Association studies have shown that gene polymorphisms in various classes of genes can modulate cancer risk. The -31G/C polymorphism in the promoter of survivin gene, affects the expression of the anti-apoptotic protein survivin which in

Functional Polymorphism in the NFE2L2 Gene Associated With Tuberculosis Susceptibility

open access: yesFrontiers in Immunology, 2021
BackgroundNuclear transcription factor erythroid 2 p45-related factor 2 (Nrf2), encoded by NFE2L2, functions as a key transcription factor and regulates expression of antioxidant genes.

Reconstructing the topology on monoids and polymorphism clones of the rationals

open access: yes, 2016
We show how to reconstruct the topology on the monoid of endomorphisms of the rational numbers under the strict or reflexive order relation, and the polymorphism clone of the rational numbers under the reflexive relation.

Factor V Leiden and thrombosis in patients with systemic lupus erythematosus: a meta-analysis. [PDF]

open access: yes, 2009
The aim of this study was to perform a meta-analysis of the association between the factor V Leiden polymorphism (FVL) and thrombosis among patients with systemic lupus erythematosus (SLE) and/or antiphospholipid antibody (aPL) positivity.

Geographic variation in walking activity in the red flour beetle Tribolium castaneum

open access: yesPopulation Ecology, EarlyView.
This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.

Different inflammatory, fibrotic, and immunologic signatures between pre-fibrotic and overt primary myelofibrosis

open access: yesHaematologica
Primary myelofibrosis (PMF) is a myeloid proliferative neoplasm (MPN) characterized by bone marrow (BM) fibrosis. Pre-fibrotic PMF (pre-PMF) progresses to overt PMF.
