Effect of Glutathione S‐Transferase and Metallothionein Polymorphisms on Mercury Levels and End‐Stage Renal Disease (ESRD) in Colombian Patients

Environmental Toxicology, EarlyView.
ABSTRACT Epidemiological studies have demonstrated a link between chronic kidney disease (CKD) and environmental mercury (Hg) exposure. Colombia has a well‐documented history of artisanal and small‐scale gold mining, where Hg exposure affects miners and nearby riverside and urban populations. This study aimed to evaluate the effects of polymorphisms in

Isolation and characterization of mitochondrial DNA from the endangered white-clawed crayfish Austropotamobius pallipes pallipes, Lereboullet, 1858

Knowledge and Management of Aquatic Ecosystems, 1996
Mitochondrial DNA (mtDNA) variation in the white-clawed crayfish, Austropotamobius pallipes pallipes, was examined by restriction endonuclease analysis of samples obtained from three geographical locations representing two very différent habitats : the ...

Interference in PCR: Transcription amplifications of mixed PVY isolates

Plant Protection Science, 2005
Interference in PCR and transcription amplifications by mixed virus templates is described. The yields of PCR amplification of closely related PVY isolates in a mixture were lower than those of the separate amplification of each individual virus strain ...

Hybridization With a Non‐Native Congener Threatens the Catalan Chub (Squalius laietanus): Optimization of a DNA‐Based Early Warning Tool

Integrative Zoology, EarlyView.
Hybridization with non‐native congeners threatens endemic freshwater fishes. Using a rapid and cost‐effective nuclear DNA assay, we detected widespread hybridization between the Catalan chub (Squalius laietanus) and the non‐native European chub (Squalius cephalus) across S.

Distribution of Calanus spp. as determined using a genetic identification system

Scientia Marina, 2004
The morphological similarity of Calanus species necessitates that the only unambiguous way of discriminating between the different species at any developmental stage is with molecular tools.

Impact of FSHB and FSHR Genes Polymorphisms on Hormonal Profile and Sperm Retrieval Outcome in Men With Klinefelter Syndrome: A Clinical–Genetic Predictive Study

Andrology, EarlyView.
ABSTRACT Background Genetic variability within the follicle‐stimulating hormone (FSH)‐related genes might contribute to phenotypic heterogeneity in patients with Klinefelter syndrome (KS), yet its clinical impact on sperm retrieval remains unclear. Objectives To investigate the association between FSHB c.211 G > T and FSHR polymorphisms (c.2039 A > G ...

Local Versus Allopatric Parasites: Acanthocephalans From Different Watersheds Are Associated With Different Infection Strategies in Definitive Host

Journal of Zoology, EarlyView.
Gammarus pulex infected by Pomphorhynchus laevis at the cystacanth larval stage. We investigated whether geographic origin influences infection success of the acanthocephalan Pomphorhynchus laevis across its complex life cycle. Parasites from different watersheds showed strong differences in infection success and virulence in intermediate hosts ...

Restriction fragment length polymorphism of ORF6 and ORF7 genes of porcine reproductive and respiratory syndrome virus (PRRSV) vaccine strains registered in the Czech Republic

Veterinární Medicína, 2006
Restriction fragment length polymorphism (RFLP) of open reading frames 6 and 7 was applied to comparative genetic analysis of live attenuated vaccine strains (Amervac-PRRS/A3, Porcilis PRRS, Ingelvac PRRS) of porcine reproductive and respiratory syndrome

Molecular confirmation of Leishmania infantum infection in the sand fly vector Phlebotomus neglectus (Diptera: Phlebotominae) in Slovenia

Medical and Veterinary Entomology, EarlyView.
Leishmania DNA was confirmed in phlebotomine sand flies collected in Slovenia. Molecular analyses confirmed Leishmania infantum in a pool of Phlebotomus neglectus females with a high parasite DNA load. The findings indicate potential conditions for local transmission and support continued entomological surveillance.
