MN•CS•IO System: Cross‐Species Study for HBB Function in High‐Altitude Hypoxia Adaptation

open access: yesAdvanced Science, EarlyView.
We developed an integrative mesh‐nanorod sorting, chitosan nanoparticle delivery, and intraosseous injection (MN•CS•IO) system to investigate HBB in high‐altitude hypoxia adaptation. Transplanting Tibetan animals' HBB‐modified Lin‐ cells into mice achieved 95.59% transfection efficiency and 8.15% HBB expression. High‐altitude HBB recipients upregulated

Cattle Raising in the United States [PDF]

open access: yes, 2020
Per capita consumption of beef rose from 85 pounds in 1960 to 114 pounds in 1970, and is projected to reach about 128 pounds by 1980. Since 1950, cattle feeding has expanded until most calves are now grain fed before slaughter.

ELF5‐Mediated Enhancer–Promoter Interaction Regulates LALBA Expression in Ovine Mammary Gland

open access: yesAdvanced Science, EarlyView.
In the study, we systematically investigate the epigenetic mechanisms underlying lactation traits in sheep by integrating transcriptomic, chromatin accessibility, histone modification, and functional analyses. We identify a super‐enhancer at the LALBA locus and demonstrate that enhancer E4 functions as its core regulatory element.

A cattle raising model for the National Livestock Farming

open access: yesCiencia Veterinaria, 2020
The objective is to represent the national production system in balance for cattle raising through a model that includes characteristic indicators at the macro level, such as weaning percentage, extraction rate, percentages of females in slaughter, death

One‐Step Induction of Oogonia‐Like and Pro‐Spermatogonia‐Like Cells From Porcine Pluripotent Stem Cells

open access: yesAdvanced Science, EarlyView.
This study established a one‐step method inducing pro‐spermatogonia‐like (activating SOX17) and oogonia‐like (activating SOX17/TFAP2C) cells from porcine pgEpiSCs with a NANOS3‐tdTomato reporter. EGF activates the core PGC program and supports survival; BMP4 further induces NANOS3 and DDX4 expression; IWR1 enhances PGCLC efficiency by suppressing ...

Gapless Complete Genome and Multi‐Omics Illuminate Immune Adaptation and Host‐Virus Interactions in a Coronavirus Reservoir

open access: yesAdvanced Science, EarlyView.
We present a complete T2T genome assembly for a key bat reservoir. Integrating population genomics, comparative genomics, transcriptomics, single‐cell omics, and functional assays, we resolve previously inaccessible genomic regions and identify evolutionary signatures associated with immune adaptation.

SOROPREVALENCIA DE LEPTOSPIROSE EM BOVINOS NAS MESORREGIÕES SUDESTE E SUDOESTE DO ESTADO RIO GRANDE DO SUL, BRASIL.

open access: yesCiência Animal Brasileira, 2012
The presence of anti-leptospira spp. aglutinins in 1360 bovine serum samples was determined in clinically healthy animals from different breeds, at more than three years old. Cattle were raised in intensive systems on 136 farms of 18 counties, 10 located

Bovine rabies cases in Ecuador: a retrospective cross-sectional observational study (2007 to 2020)

open access: yesBrazilian Journal of Biology
The hematophagous bats are usually the main reservoir of sylvatic rabies, being one of the most important viral zoonoses affecting humans and livestock in Latin America.

Hemp Cultivation and Crop Diversification: Implications for Ecosystem Services in Kentucky

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study examines the ecosystem benefits of expanding hemp cultivation by assessing its impact on crop diversity. Using scenario‐based simulations and fixed‐effect panel regressions with county‐level data in Kentucky, we find that increased hemp acreage tends to enhance crop diversity, improving water quality and bird diversity.

Delaying the Inevitable? U.S. Screwworm Closures and Feeder Cattle Market Dynamics

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Biosecurity trade restrictions are commonly framed as preventive measures, yet in many settings they function primarily as policies of delay: they impose immediate market costs while only postponing the arrival of biological risks. This paper evaluates that intertemporal tradeoff using the 2024–2025 US suspension of live cattle imports from ...
