Objective: To evaluate whether perinatal and infant outcomes differ between singleton births following assisted reproductive technology (ART) in women with endometriosis alone and those with other causes of infertility.
Design: Population-based data linkage cohort study.
Subjects: A total of 29,152 ART-conceived singleton births from 24,116 mothers, 2010-2017, New South Wales, Australia.
Viroids occur in plants as swarms of sequence variants clustered around a dominant variant, leading to adoption of the term 'quasispecies' to describe the viroid population in an individual host. The composition of the quasispecies can potentially change according to the age of the infection, the position of the leaf or branch in the canopy, and the host species. The primary aim of this study was to investigate the quasispecies concept for citrus viroid VII (CVd-VII), a recently discovered member of the family Pospiviroidae.

Article Synopsis
- Stillbirths happen globally every 17 seconds, leading to almost 2 million cases annually, and the common measure used, stillbirth rate, often overlooks important gestational age-specific trends.
- This study focused on analyzing stillbirth trends in Australia from 1998 to 2018, using three different methodologies to calculate stillbirth rates based on gestational age and risk: GS-SBR, FAR, and ccFAR.
- Results showed that the FAR and ccFAR measures provided a more accurate understanding of stillbirth risk as pregnancy progresses, highlighting distinct trends that could assist clinicians in their decision-making.
The presence of sub-micron-sized plastics in the environment has been increasing, with the possible risks of these particles remaining relatively unknown. In order to assess the toxicity of these particles, 100 nm diameter green fluorescent nano-polystyrene spheres (NPS) (20-60 mg/L) were exposed to zebra mussels () to investigate the mortality, clearance rate and stress-related biomarker responses. were collected and analysed with standard OECD toxicological tests and biomarker analysis to detect both physical and biochemical responses after exposure to NPS.

- - Citrus-associated rhabdovirus (CiaRV), a virus first identified in China in 2021, was studied using budwood from an asymptomatic kumquat plant grown in Australia, leading to the propagation of a daughter tree for further analysis.
- - Researchers extracted RNA from the green bark tissue of the daughter plant and utilized high-throughput sequencing to generate over 128 million raw data reads, which were subsequently analyzed to identify viral contigs.
- - The analysis revealed significant genetic similarities between the identified contigs and known CiaRV isolates, confirming the presence of the virus in the sample through various primer sets, resulting in the determination of a consensus genome sequence.
