Context The number of developmentally competent cumulus-oocyte complexes (COCs) retrieved during Ovum Pick-Up (OPU) determines success in both bovine and human assisted reproduction. Follicular flushing for COC retrieval is practicsed widely in humans but not in cattle. Aims To determine the benefits of follicular flushing in cattle and assess the merits of a novel 16G double-lumen needle ('OxIVF') that flushes laterally to the needle shaft.

ACS Appl Mater Interfaces
October 2024
Article Synopsis
- A series of organic dyes based on 9,9'-dihexylfluorene with unique electron-donating groups were created to improve photocatalytic hydrogen evolution (PHE) performance.
- These dyes achieved impressive results, including a turnover number (TON) of 17,400 and hydrogen production of 1,090 μmol over 126 hours under visible light.
- The research highlights that the dianchoring design significantly boosts PHE efficiency and durability compared to traditional organic dyes, marking it as a leading system for hydrogen production.
Article Synopsis
- A new study highlights the importance of considering natural hive conditions in research about honey bee microbiota, rather than relying solely on artificial lab settings.
- The research reveals that the transition in behavior from nurse bees to forager bees can significantly influence physiological and behavioral outcomes in bee studies, potentially confounding results related to microbial treatments.
- This work emphasizes the need for interdisciplinary collaboration and careful experimental design to accurately understand the complex interactions between hosts and their microbiota.
Gregarines are a large and diverse subgroup of Apicomplexa, a lineage of obligate animal symbionts including pathogens such as , the malaria parasite. Unlike , however, gregarines are poorly studied, despite the fact that as early-branching apicomplexans they are crucial to our understanding of the origin and evolution of all apicomplexans and their parasitic lifestyle. Exemplifying this, the earliest branch of gregarines, the archigregarines, are particularly poorly studied: around 80 species have been described from marine invertebrates, but almost all of them were assigned to a single genus, .

Electromyography (EMG) and near-infrared spectroscopy (NIRS) are also useful for measuring hemoglobin oxygenation for determining muscle endurance. In the present study, we aimed to evaluate the reliability and validity of muscle endurance indices derived using EMG and NIRS during a hanging task.
