Objective: To demonstrate that glass disruption beads dissociate chorionic villus samples releasing DNA from mesenchymal and cytotrophoblast cells that is suitable for processing by CVS-PCR (rapid molecular aneuploidy testing). This method is quicker than conventional methods and may limit discrepancies between PCR and karyotype in certain types of placental mosaicism.
Method: DNA was extracted from villus samples by mechanical disruption of the cells using glass beads. This method was compared to collagenase incubation followed by chelex extraction of the digested villus. PCR data generated were compared using standard criteria.
Results: DNA extracted by glass bead disruption generated data of equivalent quality to that obtained from DNA extracted using conventional collagenase and chelex-based extraction method. The case study demonstrates probable cytotrophoblast enrichment of a sample when processed by collagenase digestion and chelex incubation. Re-extraction of the digested sample by glass bead disruption resulted in cytotrophoblast and mesenchyme cells contributing to the supernatant.
Conclusion: Glass bead disruption of chorionic villus samples is an effective, inexpensive and rapid DNA extraction method that dissociates villus ensuring that DNA from both cytotrophoblast and mesenchyme cells is represented in the supernatant. Extracted DNA produced is suitable for CVS-PCR and can be stored stably at - 20 degrees C.

This study aimed to evaluate the effect of early weaning (EW) on the growth performance, gastrointestinal development, serum parameters, and metabolomics of Hu sheep lambs. Twenty-four male Hu lambs were initially ewe-reared. A total of 12 lambs were weaned at 30 d of age (D30) as the EW group, and the remaining 12 lambs were weaned at 45 d of age (D45) as the control (CON) group.

Background: Ration composition may significantly impact the nutrient absorption, duodenal parameters, intestinal health and feed efficiency of animals.
Objectives: The objective of this study was to analyse the impact of concentrate- and forage-based diets on essential morphological parameters of the duodenum, including villus height, villus width, crypt depth and goblet cell density, in three different lamb breeds.
Methods: Forty-five lambs, aged between 2.

We report a 28-year-old G2P0 at 24 weeks 5 days who presented for evaluation secondary to suspected skeletal dysplasia in her fetus. Fetal ultrasound imaging demonstrated foreshortened long bones by 9-10 weeks, multiple bowing deformities and fractures, 11 foreshortened paired ribs with fractures, decreased skull mineralization, frontal bossing, enlarged cavum septum pellucidi, and severe fetal growth restriction (< 2%). Findings were concerning for life limiting condition with thoracic circumference < 2.

Objective: To explore the genotype-phenotype correlation in a Charcot-Marie-Tooth type 2A2A (CMT2A2A) pedigree and to provide genetic counseling for its subsequent pregnancies.
Methods: A Chinese pedigree presenting with "lower limb muscle atrophy and movement disorders" at the Prenatal Diagnosis Center of Xuzhou Central Hospital between January and August 2024 was selected as the study subject. Relevant clinical data were collected from the pedigree members.

5-Fluorouracil (5-FU) is an antimetabolite widely prescribed in cancer treatments, but its use in highly proliferative tissues can cause significant problems such as mucositis. is a probiotic commonly used for protection against acute diarrhea, gastrointestinal dysbiosis and inflammatory bowel diseases. We investigated the effect of on 5-FU intestinal mucositis in mice.
