In 1998, a newly identified bacterium Taylorella asinigenitalis was isolated from the external genitalia and reproductive tracts of nurse mares, a stallion and donkey jacks in Kentucky. An extensive regulatory effort was implemented to contain the outbreak including the tracing and testing of 232 horses and donkeys on 58 premises. T. asinigenitalis was isolated from the reproductive tract of 10...

A partire dall’esperienza di etnografo-marinaio nel progetto Ermenautica, propongo inizialmente una prospettiva riduzione delle dimensioni del mare confrontando le wet ontologies (Steinberg, Peters 2019), riflessioni sulla significazione soggettiva degli oceani (Helmreich 2010, 2019) e il discorso sui regimi planetarietà in campo umanistico (Chakrabarty, Latour 2020). Successivamente, concentra...

Ferritins, an ancient family of protein nanocages, concentrate iron in iron-oxy minerals for iron-protein biosynthesis and protection against oxy radical damage. Of the two genetic mechanisms that regulate rates of ferritin-L synthesis, DNA transcription and mRNA translation, more is known about mRNA regulation where iron targets complexes of an mRNA structure, the iron-responsive element (IRE)...

Medical problems in the last month of pregnancy may have devastating effects on the foal or both the mare and the foal. This paper will review the most common medical complaints in the last month of pregnancy in the mare. A general overview of the evaluation of the colicky mare in advanced pregnancy is provided as a guideline for differentiation between genital and nongenital causes of colic. D...

In the literature on measured wage inequality, only one recent study, by Glaeser and Mare′ (2001), has focused on the enormous wage gap between urban and non-urban workers in the United States. In the present paper, I replicate and extend Glaeser and Mare′’s original empirical work, and I present a new interpretation of the evidence based on my re-estimation. Contrary to Glaeser and Mare′’s the...

A nulliparous non-descript mare was presented with a complaint of dystocia. The mare was recumbent and physical examination revealed that the animal was in shock. There was no straining and foetal forelimbs were visible outside the vulva. The foetus was dead as there was no pedal reflex. Vaginal examination revealed anterior presentation with dorso-sacral position and rigid lateral head deviati...

OBJECTIVE This prospective study aims to compare three different sampling techniques for the collection of endometrial cytological specimens in the mare: the guarded culture swab, the uterine cytobrush and the low volume uterine flush. MATERIAL AND METHODS The study population consisted of six healthy Standardbred mares in dioestrus. In each mare an acute endometritis was induced by performin...

The theory of ejaculate economics was mainly built around different sperm competition scenarios but also predicts that investments into ejaculates depend on female fecundity. Previous tests of this prediction focused on invertebrates and lower vertebrate, and on species with high female reproductive potential. It remains unclear whether the prediction also holds for polygynous mammals with low ...

Three-dimensional (3D) structure of a new form of diferric mare lactoferrin has been determined at 3.8 A resolution. The protein was crystallized in a space group P2(1)2(1)2(1) with a = 80.1 A, b = 103.7 A, c = 112.2 A with a solvent content of 57%. The structure was solved by molecular replacement method using the model of native mare lactoferrin. The structure has been refined using X-PLOR to...

Shortening of the deep digital flexor tendon was performed by tenotomy, overlapping and anastomosis. The procedure was performed on a two-year-old Quarter Horse Mare with distal interphalangeal joint hyperextension with subluxation and metatarsophalangeal joint hyperextension. These problems originated from damage to the digital flexor tendons, presumably due to previous distal limb trauma. The...
