Safe and Stable Germline Transmission of MSTN Mutations in Cattle

open access: yesAnimal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT With the global population expected to reach 10 billion by 2050, sustainable livestock production is critical. Gene editing of the myostatin (MSTN) gene represents a promising strategy to enhance muscle growth in cattle. In this study, MSTN‐mutated founder (F0) cows were used to generate F1 offspring via ovum pick‐up, in vitro fertilization ...

Comparison of gonadotropin-releasing hormone and estradiol benzoate plus gonadotropin-releasing hormone to initiate a progesterone-based timed artificial insemination resynchronization protocol in lactating dairy cows

open access: yesJournal of Dairy Science
: The present study compared 2 strategies to initiate a progesterone (P4)-based timed artificial insemination (TAI) protocol for lactating dairy cows: only GnRH or estradiol benzoate (EB) plus GnRH (EB+GnRH).

Discrete Timed Automata [PDF]

open access: yes, 2005
MONA implements an efficient decision procedure for the logic WS1S, and has already been applied in many non-trivial problems. Among these, we follow on from previous work done by Smith and Klarlund on the verification of a sliding-window protocol.

Weighted Single‐Step GWAS Reveals Genetic Mechanisms Underlying Pregnancy Loss in Early Nellore Heifers

open access: yesAnimal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT Pregnancy loss (PL) affects reproductive efficiency in beef cattle, yet its genetic architecture remains poorly understood in Bos indicus populations. Here, PL was defined as failure from pregnancy diagnosis to calving, capturing a window approximately 60 days after the breeding season.

Integrating cryobanks into conservation frameworks: The case of boreal caribou in Ontario

open access: yesConservation Science and Practice, Volume 8, Issue 10, October 2026.
Conservation cryobanks are a powerful but underutilized complement to conventional recovery strategies such as habitat protection and population monitoring. Here, we present a transferable, stepwise framework for integrating cryobanking into formal species recovery plans, including guidance on population prioritization, partner engagement, and the ...

A Spatial Clustering Approach of Economic Activities: An Application to the Agribusiness Sector in Brazil's Midwest Region

open access: yesGeographical Analysis, Volume 58, Issue 4, October 2026.
ABSTRACT The spatial distribution of economic activities is central to regional economics. However, empirical tools for comparing industries based on the similarity of their spatial distributions remain limited. Traditional cluster analysis typically ignores geographical distance and connectivity, while spatial methods focus on clustering places rather

Compositional detection of Zeno behavior in Timed Automata with Deadlines [PDF]

open access: yes, 2009
We present a compositional analysis to detect Zeno behavior in Timed Automata with Deadlines. A syntactic analysis is defined, based on Tripakis' strong non-Zenoness property, which identifies all elementary cycles where Zeno behavior may occur.

Failure of Artificial Insemination of Husband's Semen in the Treatment of Male Infertility

open access: yes, 1996
In the management of infertility, in case semen quality is found insufficient and could not be improved by medical means, handling the available spermatozoa in the most beneficial way has been aimed.

Seminal Extracellular Vesicles as Molecular Modulators of Male Reproductive Function

open access: yesReproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
ABSTRACT Extracellular vesicles (sEVs) contained in seminal plasma (SP) maintain, in concert with free SP‐components (proteins, hormones, cytokines, metabolites and antioxidants) under an endocrine umbrella the functional in vivo homeostasis of ejaculated spermatozoa. The sEVs define a generic mixture of nanovesicles delivered by male epithelial cells,
