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.

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 ...

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.

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

BUSCA DE MARCADORES MOLECULARES PREDITIVOS DO ACOMETIMENTO DE LINFONODOS EM CARCINOMAS PAPILÍFEROS DE TIREOIDE

Revista UniVap, 2022
O câncer de tireoide é a neoplasia que mais cresce em incidência todos os anos, sendo o carcinoma papilífero de tireoide (CPT) o subtipo mais comum. Em muitos casos estes tumores podem se tornar agressivos, ocasionando metástases linfonodais.

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

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.

Morphologic and molecular characterization of Myrciaria spp species Caracterização morfológica e molecular de espécies de Myrciaria spp

Revista Brasileira de Fruticultura, 2005
The jabuticaba tree is considered one of the most typical Brazilian fruit trees. However, few studies of this plant are found in the literature and even its botanical classification is very controversial.

Phylogenomic approach to integrative taxonomy resolves a century‐old taxonomic puzzle and the evolutionary history of the Acromyrmex octospinosus species complex

Systematic Entomology, Volume 50, Issue 3, Page 469-494, July 2025.
A comprehensive, integrative study approach combining morphology, population genetics, phylogenetics and biogeography revealed that the Acromyrmex octospinosus species complex consists of two species: A. octospinosus and its social parasite A. insinuator.
