Immunocontraception targeting the zona pellucida shows promise as a safe, effective and economically feasible method for controlling feral horse populations that roam public rangelands throughout the United States. The efficacy of porcine zona pellucida (pZP) vaccines to generate high titers can be evaluated with an indirect immunofuorescence assay or a...
The Bureau of Land Management (BLM) maintains a growing number of feral horses on public rangelands. With population growth rates as high as 22% annually, herds are exceeding their carrying capacity and millions of dollars are spent maintaining captured horses in holding facilities awaiting adoption. To manage the feral horse...
The effects of five cytokinin antagonists on the growth
of cytokinin-autonomous lines of Phaseolus lunatus cv.
Kingston, Phaseolus vulgaris cv. Great Northern, and
Nicotiana tabacum cv. Wisconsin 38 callus tissues have been
compared. The antagonists tested included four N⁴-substituted 4-amino-2-methylthiopyrrolo[2,3-d]pyrimidines
bearing the following N⁴ side chains, 4-n-pentyl-
(ms²pnN⁴Prp), 4-n-hexyl- (ms²HxN⁴Prp),...
Sperm acrosome associated 3 protein (SPACA3) is a unique, intra-acrosomal, conventional-type lysozyme-like protein of mammalian spermatozoa. SPACA3 is present in all stages of ovarian follicles and is localized to granulosa cells and ooplasma in humans, mice, cows, dogs, and cats. The objective of this study was to determine if equine...
Wild horse and burro management has been a controversial topic over the past several decades, since the passing of the Wild and Free-Roaming Horses and Burro Act of 1971, as federal land management agencies attempt to manage wild horses and burros in a way that supports natural ecological balance. In...
The current American free-roaming horse (Equus caballus) population far exceeds the appropriate population limit set by the Bureau of Land Management (BLM) to preserve resources on public lands. Several techniques have been tested to assist in decreasing repopulation rates. The purpose of the present study was to analyze two contraceptive...
Dechlorination of 2,4,6-trichlorophenol was performed within a magnetically stabilized fluidized bed (MSFB), containing a palladized iron (Pd/Fe) catalyst entrapped within alginate beads. Kinetic parameters of this multistep reaction yielding phenol as a final product were preliminarily defined in a batch system using four different intermediates as substrates for Pd/Fe catalyzed...
We introduce a numerical criterion which allows us to bound the degree of any algebraic integer having all of Galois conjugates in an interval of length less than 4. Using this criterion, we study two arithmetic dynamical questions with local rationality conditions. First, we classify all unicritical polynomials defined over...
Prolactin (PRL) is a peptide hormone that is involved in a number of diverse physiologic roles, particularly with respect to reproduction, including: influencing sexual and parental behaviors, onset of puberty, regulation of seasonal reproduction, follicular maturation, ovulation, luteinization and corpus luteum (CL) function, steroidogenesis, mammary gland development and lactation, testicular...
Some recent studies have shown the outstanding price linkages at the global scale between the cannery-grade
tuna markets over the last decade. When it comes to price transmission along the European value chains, opposite results between the two major species (skipjack and yellowfin) are found: the market for final goods...
