Characterization of indigenous chicken phenotypes in Liban Jawi District, Ethiopia: A qualitative and quantitative analysis.
PLoS One

Department of Animal Science, College of Agriculture and Veterinary Science Ambo University Mamo Mezemir Campus, Guder, Ethiopia.
Indigenous chickens play a crucial role in the livelihoods of smallholder farmers in rural Ethiopia. This study aimed to phenotypically characterize indigenous chickens in the Liban Jawi district, focusing on measurements of phenotypic characteristics. The multi-stage sampling method selected 192 households with at least two mature indigenous chickens from 2,166 households, resulting in the sampling of 224 chickens (138 females and 86 males) for phenotypic characterization.

Primordial germ cells (PGCs), the progenitors of gametes, are essential for teleost reproduction. While their formation is conserved across teleosts, the activation, migration routes, and localization periods vary among species. In this study, we developed a novel transgenic line, Tg(ddx4:TcCFP13-nanos3), based on the Nile tilapia genome, to label PGCs with clear fluorescent signals in the freshwater angelfish (Pterophyllum scalare).

Article Synopsis
- Advance care planning is crucial in palliative care, yet public acceptance varies across different age groups; a study in China revealed an overall acceptance score of 64.03 with younger individuals showing the highest acceptance at 67.13.
- Various factors such as death education, health literacy, and social support significantly influence acceptance in nonage through old age.
- The findings highlight the need for targeted strategies considering these influencing factors to improve public acceptance and implementation of advance care planning across different life stages.
Power electronics for green hydrogen generation with focus on methods, topologies, and comparative analysis.

This research article meticulously examines advanced power electronic converters crucial for optimizing electrolyzer perfor- mance in hydrogen production systems. It conducts a thorough review of mature electrolyzer types, detailing their specifications, electric models, manufacturers, and scalability. To meet the high current and stable DC voltage demands of industrial electrolyzers, the study delves into a broad spectrum of AC-DC and DC-DC converter topologies.

Erythroid enucleation, the penultimate step in mammalian erythroid terminal differentiation, is a unique cellular process by which red blood cells (erythrocytes) remove their nucleus and accompanying nuclear material. This complex, multi-stage event begins with chromatin compaction and cell cycle arrest and ends with generation of two daughter cells: a pyrenocyte, which contains the expelled nucleus, and an anucleate reticulocyte, which matures into an erythrocyte. Although enucleation has been compared to asymmetric cell division (ACD), many mechanistic hallmarks of ACD appear to be absent.
