Economic benefit in repeat breeder cows using intrauterine infusion of penicillin and estrus synchronization followed by timed artificial insemination

Journal of Advanced Veterinary and Animal Research, 2018
Objective: Until recently, management of repeat breeding in cattle remains a major problem to dairy farmers. This study was carried out to improve the fertility in cows, those did not conceive after three or more consecutive services.

Comparative Study of Pregnancy Rate of Dairy Cows Inseminated with Fresh or Frozen-Thawed Semen

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2020
The aim of this study was to investigate conception rates (CR) achieved with artificial insemination of Holstein cows using fresh or frozen insemination doses (ID). The synchronization protocols (Double-Ovsynch, Ovsynch, ReSynch) and pedometers were used

A single dose of FSH or hCG during a split-time AI program did not enhance follicular growth or pregnancy per artificial insemination in beef heifers

Journal of Applied Animal Research, 2023
The objective of this study was to evaluate the effect of a low dose of hCG or FSH on follicle growth and pregnancy per artificial insemination (AI) in crossbreed beef heifers subjected to a split-time AI program.

Smaller is better: nanobodies meet NMR

FEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

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

, 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.

Testing timed systems modeled by stream X-machines [PDF]

, 2009
Stream X-machines have been used to specify real systems where complex data structures. They are a variety of extended finite state machine where a shared memory is used to represent communications between the components of systems.

Timed artificial insemination plus heat I: effect of estrus expression scores on pregnancy of cows subjected to progesterone–estradiol-based protocols

Animal, 2019
Expression of estrus near timed artificial insemination (TAI) is associated with greater fertility, and estrus detection could improve TAI fertility or direct TAI management, although accurate estrus detection can be difficult and time-consuming using ...

Comparison of plasma concentrations of estradiol-17β and progesterone, and conception in dairy cows with cystic ovarian diseases between Ovsynch and Ovsynch plus CIDR timed AI protocols.

Journal of reproduction and development, 2011
The objectives of this study were 1) to determine the effects of adding a CIDR to the Ovsynch protocol on plasma concentrations of estradiol-17β and progesterone and conception in dairy cows with cystic ovarian diseases and 2) to examine associations ...

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

FEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Compositional Detection of Zeno Behaviour in Timed Automata [PDF]

, 2006
The formal specification and verification of real-time systems are difficult tasks, given the complexity of these systems and the safety-critical role they usually play. Timed Automata, and real-time model-checking, have emerged as powerful tools to deal
