DNA methylation epigenotypes in breast cancer molecular subtypes
(BioMed Central, 2010-09-29)
Introduction: Identification of gene expression-based breast cancer subtypes is considered a critical means of prognostication. Genetic mutations along with epigenetic alterations contribute to gene-expression changes ...
Transcription of ribogenesis genes in fish gonads: Applications in the identification of stages of oogenesis and in environmental monitoring of intersex condition
(Elsevier, 2017-06-13)
One of the best described effects of environmental xenoestrogens in fish is the generation of intersex gonads in males. Considering 5S rRNA a marker of the presence of oocytes, a 5S/18S rRNA index was calculated in 296 ...
Acute toxicity of zinc and arsenic to the warmwater aquatic oligochaete Branchiura sowerbyi as compared to its coldwater counterpart Tubifex tubifex (Annelida, Clitellata)
(Springer, 2016-07-12)
Purpose This study aimed at evaluating the acute effects of arsenic and zinc to the warmwater aquatic oligochaete Branchiura sowerbyi. Relative sensitivity with the coldwater species Tubifex tubifex was compared. Implications ...
Sediment toxicity and bioaccumulation assessment in abandoned Copper and Mercury mining areas of the Nalón River basin (Spain)
(Springer, 2014-11-06)
Sediment toxicity and metal bioaccumulation were assessed at sites affected by historical copper (Cu)
and mercury (Hg) mining activities in the Nalón River basin, Asturias, Spain. Toxicity assessment of stream sediments ...
Biodiversity of groundwater oligochaetes from a karst unit in northern Iberian Peninsula: ranking subterranean sites for conservation management
(Springer, 2008-03-05)
El presente estudio sugiere que la unidad kárstica de Santa Eufemia-Ereñozar en el norte de la Península Ibérica es un hotspot de biodiversidad para los oligoquetos de aguas subterráneas, debido a (1) la presencia de un ...
Integrative taxonomy of the freshwater worm Rhyacodrilus falciformis s.l. (Clitellata: Naididae), with the description of a new species
(Wiley, 2013-08-21)
[ES] La variación genética y morfológica dentro de Rhyacodrilus falciformis Bretscher, 1901 (Clitellata: Naididae) en Europa se exploró utilizando un enfoque integrador, con tres marcadores genéticos no vinculados (la ...
Phylogenetic analysis of oligochaete Tubificinae (Annelida : Clitellata) based on mitochondrial sequence data
(CSIRO Publishing, 2011-11-18)
[ES]Se utilizaron secuencias parciales de los genes mitocondriales 16S rRNA y citocromo c oxidasa subunidad I (COI) (1) para resolver las relaciones internas de la subfamilia Tubificinae (Annelida: Clitellata) y (2) para ...
Seaweed: Nutritional and gastronomic perspective. A review
(Elsevier, 2024)
Seaweed are organisms rich in many bioactive compounds such as proteins, minerals, vitamins, fibers, essential amino acids, pigments, and fatty acids, which give them extraordinary antihypertensive, antidiabetic, antioxidant, ...
Assessment of the effectiveness of antifouling solutions for recreational boats in the context of marine bioinvasions
(Elsevier, 2024-03)
The recreational boating sector is a major vector for the introduction of non-indigenous species (NIS) via biofouling. Despite applying control measures to prevent the growth of fouling communities, most vessels are NIS ...
Toxicogenomics of the Freshwater Oligochaete, Tubifex tubifex (Annelida, Clitellata), in Acute Water-Only Exposure to Arsenic
(MDPI, 2024-03-16)
A toxicogenomic approach was used for toxicity evaluation of arsenic in the aquatic environment, and differential gene expression was investigated from 24 h and 96 h water-only acute toxicity tests with the aquatic ...
