Human Genetic Variation and Parkinson’s Disease [PDF]

open access: yesJournal of Movement Disorders, 2010
Parkinson’s disease (PD) is a chronic neurodegenerative disorder with multifactorial etiology. In the past decade, the genetic causes of monogenic forms of familial PD have been defined.

Genomic introgression mapping of field-derived multiple-anthelmintic resistance in Teladorsagia circumcincta [PDF]

open access: yes, 2017
Preventive chemotherapy has long been practiced against nematode parasites of livestock, leading to widespread drug resistance, and is increasingly being adopted for eradication of human parasitic nematodes even though it is similarly likely to lead to ...

Variation in the flowering time orthologs BrFLC and BrSOC1 in a natural population of Brassica rapa. [PDF]

open access: yes, 2015
Understanding the genetic basis of natural phenotypic variation is of great importance, particularly since selection can act on this variation to cause evolution.

Genetic Variation and the Control of Transcription

open access: yesCold Spring Harbor Symposia on Quantitative Biology, 2003
Identifying and understanding genetic variation is akey driver of agricultural, biotechnological, and biomedical research and commercialization; the major focus ofgenetic variation research has until now been on changesto protein-coding sequences because these are computationally and experimentally accessible.

Natural genetic variation in MIR172 isolated from Brassica species

open access: yesBiologia Plantarum, 2014
The present study reports a natural variation in microRNA172 (MIR172) family members isolated from six species of genus Brassica. The analysis of nucleotide polymorphism across 44 Brassica MIR172 homologs revealed a higher conservation in the predicted ...

Genetic–environment associations explain genetic differentiation and variation between western and eastern North Pacific rhinoceros auklet (Cerorhinca monocerata) breeding colonies

open access: yesEcology and Evolution
Animals are strongly connected to the environments they live in and may become adapted to local environments. Examining genetic–environment associations of key indicator species, like seabirds, provides greater insights into the forces that drive ...

Disease-Associated Streptococcus pneumoniae Genetic Variation

open access: yesEmerging Infectious Diseases
Streptococcus pneumoniae is an opportunistic pathogen that causes substantial illness and death among children worldwide. The genetic backgrounds of pneumococci that cause infection versus asymptomatic carriage vary substantially.

Plant gene bank collections - sources of variation in health substances [PDF]

open access: yes, 2007
Gene banks and national plant genetic resources programmes have been established to conserve genetic resources of domesticated plants. Variation of the beneficial health substances found in plants is the result of growing conditions (environment) and ...

IL28B polymorphisms predict the response to chronic hepatitis C virus infection treatment in a Mexican population

open access: yesAnnals of Hepatology, 2012
Introduction. The treatment of hepatitis C virus (HCV) genotype 1 with ribavirin (RBV) and pegylated-interferon alpha (peg-IFNα) provides a low-level sustained virological response (SVR).
