Cell‐free DNA 5‐hydroxymethylcytosine as a marker for common cancer detection

Clinical and Translational Discovery, Volume 2, Issue 4, December 2022., 2022
Graphical Abstract: We discovered highly sensitive plasma cell–free DNA (cfDNA) 5‐hydroxymethylcytosine (5hmC) signatures to detect common cancers, including bladder, breast, colorectal, kidney, lung and prostate cancer. We developed a plasma cfDNA 5hmC signature to accurately predict cancer origin.

Identification of a candidate sex determination gene in Culaea inconstans suggests convergent recruitment of an Amh duplicate in two lineages of stickleback

Journal of Evolutionary Biology, Volume 35, Issue 12, Page 1683-1695, December 2022., 2022
Sex chromosomes vary greatly in their age and levels of differentiation across the tree of life, largely due to the rates of sex chromosome turnover in different lineages. Here, we identify a novel, and likely young, turnover in stickleback fishes. Using whole‐genome sequencing we identify AmhY, a male specific duplication of the autosomal gene Amh, as

Basic studies on the culture of pejerrey. I. PNR, histology and morphometry of starved pejerrey Odontesthes bonariensis larvae.

NIPPON SUISAN GAKKAISHI, 1989
Histological and morphometric examinations were conducted on normally fed and starved larvae of pejerrey Odontesthes bonariensis, a freshwater Atherinid fish, to investigate criteria for the assessment of nutritional condition. In addition, results of survival of larvae starved throughout or fed after progressively longer periods of starvation are ...

Occurrence and control of Chilodonella spp. in pejerrey Odontesthes bonariensis [PDF]

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2011
O presente trabalho teve por objetivo relatar a ocorrência e controle de infecção parasitária por Chilodonella spp. em alevinos de peixe-rei (O. bonariensis). A Chilodonella spp. é um ciliado que parasita tegumento e brânquias de peixes, podendo ocasionar grande mortalidade.

Primary Structure of a Novel Gonadotropin-Releasing Hormone in the Brain of a Teleost, Pejerrey* [PDF]

Endocrinology, 2001
The neuropeptide GnRH is the major regulator of reproduction in vertebrates acting as a first signal from the hypothalamus to pituitary gonadotropes. Three GnRH molecular variants were detected in the brain of a fish, pejerrey (Odontesthes bonariensis), using chromatographic and immunological methods.

Biological traits and growth patterns of pejerreyOdontesthes argentinensis

Journal of Fish Biology, 2012
This study assesses for the first time the relationship between annual cycles of different biological indices with growth patterns of a marine pejerreyOdontesthes argentinensispopulation near its southern‐distribution boundary in North Patagonia. The reproductive period is between September and November evidenced by an increase in the gonado‐somatic ...

Main diseases of pejerrey (Odontesthes bonariensis) in central Argentina [PDF]

Pesquisa Veterinária Brasileira, 2006
Argentina's central region includes an important area covered by shallow pampean lakes and dams. In these environments, fishing of pejerrey Odontesthes bonariensis Valenciennes, 1835 (Pisces, Atherinopsidae), the most important fresh-water fish of the country, is a relevant social activity and also a considerable economic resource.

Aspectos biológico-pesqueros del pejerrey (Odontesthes regia regia) en el puerto de Ilo durante 1996-1998

Revista Peruana de Biología, 2014
Se analizaron los aspectos biológicos y pesqueros del pejerrey peruano (Odontesthes regia regia) población en Ilo, desde enero de 1996 a septiembre de 1998. Las capturas fueron tres veces más alta (72,76 t) que las de 1996 hasta 1997, mientras que con el

Assessment of condition in pejerrey Odontesthes bonariensis (Atheriniformes: Atherinopsidae) populations: which index works best?

Neotropical Ichthyology
The pejerrey Odontesthes bonariensis is the most important target species in temperate freshwater fisheries of Argentina, and assessment of condition has been a regular practice and common diagnostic tool. Most pejerrey fishery studies have used Fulton's
