Low‐Dose Aspirin in the Prevention of Recurrent Spontaneous Preterm Birth Stratified by Placental Maternal Vascular Malperfusion: Secondary Analysis of a Randomized Trial

open access: yesBJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Objective To evaluate the effectiveness of low‐dose aspirin in the prevention of recurrent preterm birth (PTB) in women with signs of maternal vascular malperfusion (MVM) in the placenta of the previous spontaneous PTB. Design Secondary analysis of the APRIL study.

Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

The association between male infertility and sperm disomy: Evidence for variation in disomy levels among individuals and a correlation between particular semen parameters and disomy of specific chromosome pairs [PDF]

open access: yes, 2004
BACKGROUND: The association between infertility and sperm disomy is well documented. Results vary but most report that men with severely compromised semen parameters have a significantly elevated proportion of disomic sperm.

Influence of Post-Mortem Sperm Recovery Method and Extender on Unstored and Refrigerated Rooster Sperm Variables

open access: yes, 2015
Contents Many post-mortem sperm collection techniques have been described for mammalian species, but their use in birds is scarce. This paper compares the efficacy of two post-mortem sperm retrieval techniques - the flushing and float-out methods - in ...

Multi‐Omics Analysis Reveals Coordinated Adaptations in Genes, Metabolism, and Gut Microbiota Underpinning Herbivory in Lordiphosa Flies

open access: yesIntegrative Zoology, EarlyView.
Multi‐omics analysis reveals that herbivorous adaptation in Lordiphosa flies arises from coordinated interactions across the genome, transcriptome, and gut microbiota: genomic expansions of detoxification (e.g., cytochrome P450s) and carbohydrate metabolism gene families, transcriptomic upregulation of energy pathways like lipid oxidation and ...

Fishing Activity Affected Odontocete Cetacean Distribution in a Marine Protected Area in the East China Sea

open access: yesIntegrative Zoology, EarlyView.
Spatiotemporal distribution of odontocete cetaceans within China's Jiushan Archipelago National Nature Reserve was investigated. Fishing vessels significantly reduced both cetacean acoustic detections and feeding activity, whereas gillnets selectively suppressed cetacean feeding behavior without affecting overall cetacean detection rates.

The Australian Hydromyine Rodents—Their Interspecific Diversity and Reproductive Biology: A Review

open access: yesIntegrative Zoology, EarlyView.
There are two major groups, the Rattus species and the Hydromyini, in Australia. Clearly, the hydromyine rodents, unlike the Rattus genus, exhibit a diverse array of reproductive biological traits in both males and females, the full evolutionary significance of which has yet to be ascertained.

From fluke to fragment: A multifaceted method for molecular sex identification and mitochondrial haplotyping from environmental DNA samples

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Environmental DNA (eDNA) analyses have become a powerful tool for non‐invasive biodiversity monitoring, yet the applicability of population‐genetic approaches to environmental samples remains largely unexplored. Even when genetic traces originate from a single individual, low target DNA concentrations and amplification or sequencing artefacts ...

Proteomic biomarkers in seminal plasma as predictors of reproductive potential in azoospermic men

open access: yesFrontiers in Endocrinology
IntroductionAzoospermia, characterized by an absence of sperm in the ejaculate, represents the most severe form of male infertility. While surgical sperm retrieval in obstructive azoospermia (OA) is successful in the majority of cases, patients with non ...
