Placental insufficiency markers to assess the risk of non‐chromosomal genetic conditions in early‐onset fetal growth restriction

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 4, Page 492-499, April 2026.
ABSTRACT Objectives To assess the value of placental insufficiency markers for estimating the risk of genetic anomalies in fetuses with isolated early‐onset fetal growth restriction (FGR), defined as an estimated fetal weight ≤ 3rd percentile diagnosed ≤ 28 + 6 weeks' gestation.

Indução hormonal da ovulação e desmame precoce na fertilidade pós-parto de vacas de corte homozigotas e heterozigotas para o microssatélite BMS3004 Hormonal induction of ovulation and early weaning in postpartum fertility of homozigous and heterozigous beef cows for the microsatellite BMS3004

Revista Brasileira de Zootecnia, 2003
O objetivo deste experimento foi comparar a eficiência de um programa hormonal associado ao desmame temporário por 96 horas na indução do estro e ovulação com o desmame definitivo aos 60 dias em vacas de corte.

Ultrasound features in early pregnancy for predicting abnormal karyotype in first‐trimester miscarriage

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 3, Page 376-384, March 2026.
ABSTRACT Objective To investigate whether combining abnormal morphological features observed on ultrasound in live pregnancies that ended in a first‐trimester miscarriage can predict an abnormal karyotype. Methods This retrospective observational cohort study was conducted at the early‐pregnancy assessment unit at University College London Hospital ...

A new phylogeny of Anastrepha (Diptera: Tephritidae) based on nuclear loci obtained by phylogenomic methods

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
We present an extensive phylogenetic analysis, based on 293 nuclear loci and 728 individuals representing 237 species of Anastrepha, the largest and most economically important New World genus of Tephritidae. The analysis strongly supports the monophyly of most Anastrepha species groups, also revealing previously unknown relationships among species and

Pixelated pathologies: Camera trapping as a tool for monitoring wildlife health

Journal of Applied Ecology, Volume 62, Issue 11, Page 2894-2913, November 2025.
Given the increasing emergence of diseases, some with conservation and public health implications, improving and expanding wildlife health surveillance strategies is imperative. Camera trapping is particularly relevant for detecting new outbreaks, monitoring high‐risk zones and evaluating risk mitigation measures. Abstract Camera trapping has become an

Marcadores moleculares para qualidade de ovocitos bovino

SPERMOVA, 2017
Oocyte selection using morphological criteria is currently used, but this selection approach has limitations in terms of accuracy, objectivity, and constancy. Therefore, the development of new methods that could allow the identification of molecular markers that can predict the oocyte competency more accurately is needed.

Taxon‐specific BLAST percent identity thresholds for identification of unknown sequences using metabarcoding

Methods in Ecology and Evolution, Volume 16, Issue 10, Page 2380-2394, October 2025.
Abstract The identification of organisms in environmental samples using metabarcoding relies on factors such as taxonomic assignment methods, genetic markers, reference databases and confidence thresholds for taxonomic assignment. Because lineages evolve at different rates, a global threshold (e.g.
