Folin M, Gennari G, Jori G.The irradiation of horse and sperm-whale Fe” or Fez’ myoglobins with visible light
showed that axial ligands that render the heme diamagnetic (e.g. 02, CO or CN-) endow the
hemoproteins with a marked photosensitivity. In contrast, high-spin myoglobins are unaffected by
visible light. These findings appear to be of general validity for all hemo-proteins and are in agreement
with the involvment of the triplet state of the heme as the reactive intermediate. In all cases, the overall
photoprocess occurs within a very narrow spatial range, leading to specific modification of these
photoox...
Augustinsson KB, Bartfai T, Mannervik B.The steady-state kinetics of the butyrylcholinesterase-catalysed hydrolysis of butyrylthiocholine and thiophenyl acetate were shown to deviate from Michaelis-Menten kinetics. The ;best' empirical rate law was selected by fitting different rate equations to the experimental data by non-linear regression methods. The results were analysed in view of two alternative interpretations: (1) the reaction is catalysed by a mixture of enzymes, or (2) the activity is due to a single enzyme displaying deviations from Michaelis-Menten kinetics. It was concluded that the second alternative applies, and this...
Margalit R, Schejter A.The specific binding of cations to horse heart ferrocytochrome c has been studied, using the gel
filtration method. The cations investigated were: Mg2+, Co2+, cinchonine and proflavine. The stability
constants are in the range of 5-8 mM-1, and the number of binding sites per protein molecule are
1 to 2. The temperature dependence of the stability constant for the Mg2+-ferrocytochrome system
was measured. The thermodynamic parameters were found to be: dH&s = 4-12 kcal/mol, dG;,,
(25 "C) = -5.6 kcal/mol and AS&, = +57 calxmol-lx K-I.
Barrachina L, Ivanovska A, Eslami Arshaghi T, O'Brien A, Cequier A, Murphy M, Hollinshead F, Rodellar C, Barry F.Regenerative therapies are quickly expanding to application in equine patients because of their importance as sporting and companion animals. Furthermore, aligning with a One Health concept, veterinary medicine offers a unique platform for preclinical studies. While mesenchymal stem/stromal cells (MSCs) therapies are already used in treating horses, strategies involving induced pluripotent stem cells (iPSCs) are poorly developed. iPSCs present great potential for therapy and disease modelling, but their consistent generation in horses requires further investigation into the source of somatic c...
Watanabe M, Sato F, Innan H.We investigated the changes in inbreeding levels in Japanese Thoroughbred horses over the past 46 years. Our results show a significant increase in inbreeding over the past 30 years, primarily due to the influence of two sires, Northern Dancer and Sunday Silence. Northern Dancer's bloodline spread gradually through descendants like Northern Taste, leading to a slower increase in the inbreeding coefficient. In contrast, Sunday Silence was directly imported and became a leading sire, causing a rapid increase in his blood proportion and inbreeding coefficient. Our findings suggest that monitoring...
Kneipp MLA, Sousa LN, Cota LO, Malacarne BD, Winter IC, Santana CH, Santos RL, Xavier ABS, Faleiros RR, Carvalho AM.Coxofemoral dysplasia is a condition characterized by the abnormal development and flattening of the femoral head and deformities in the acetabulum, leading to joint instability. Although described in various animal species, it is uncommon and rarely reported in horses. This article presents a case of incapacitating coxofemoral dysplasia diagnosed in a four-month-old foal Mangalarga Marchador, which exhibited lameness in the hind limbs, thoracolumbar kyphosis, gluteal muscle atrophy, and pronounced sensitivity during pelvic limb flexion. The clinical diagnosis indicative of bilateral coxofemor...

Semanchik PL, Wesolowski LT, Artman JL, Seward RL, Beer C, Barnes ED, White-Springer SH.Reactive oxygen species are normal by-products of cellular metabolism but may have detrimental effects on cellular matrices and excite inflammatory pathways when overproduced. To test the hypothesis that supplementation of an herbal extract combination would: 1) improve antioxidant status; 2) increase anti-inflammatory cytokines; and 3) decrease pro-inflammatory cytokines, 40 mature, sedentary stock-type horses (32 mares, 8 geldings, mean±SD; 15.7 ± 4.9 yr, 519 ± 46 kg) were stratified by age, sex, and body weight and randomly assigned to one of four dietary treatment groups for 5...
Hidalgo M, Ortiz I.Sperm vitrification is a novel-assisted reproductive technique that is increasingly gaining relevance in the last years. This technique allows to cryopreserve sperm from valuable stallions and donkeys without the exposure to permeable cryoprotectants, particularly toxic for the gametes of these species.This chapter aims to describe the current range of methodologies available that are key to ensure sperm quality after vitrification and warming of stallion and donkey sperm.
Miró J, Martínez-Rodero I, Yeste M, Catalán J.Cryopreservation is currently the only strategy for long-term conservation of equine sperm. To get optimal post-thaw sperm survival, carefully following each step of the freezing protocol is crucial. First, one needs to obtain and exhaustively analyze an ejaculate of good sperm quality. Then, the seminal plasma is removed by centrifugation, and the resulting pellet is resuspended in a certain volume of the freezing medium to reach the right sperm concentration. Finally, sperm samples are packaged into 0.5-mL straws, cooled, and frozen using an automatic, controlled-rate freezer. Once the tempe...

Kaminski M, Metenier L, Sykiotis M, Ryder OA, Demontoy MC.1. Among several species of Equidae only E. przewalskii possesses a serum esterase identical with that of E. caballus. 2. The esterases of Hemionidae differ slightly from that of domestic horse by electrophoretic migration and by antigenic structure. 3. Zebras (grevyi, burchelli) appear devoid of this component but Z. hartmannae possesses an esterase of high enzymatic activity, differing notably from that of horse by electrophoretic and antigenic properties.

Faulk C.Sequencing a genome by students has now become practical as we demonstrated with our recent publication of the Przewalski's horse (Equus ferus przewalskii) genome. In this review, I describe my experience teaching genome assembly in the classroom. In my course, students sequenced, assembled, and published a high-quality genome for Przewalski's horse using Oxford Nanopore long-read sequencing with only $4000 of materials. Along with the genome, we assembled the mitochondrial genome, sequence variants, predicted gene annotations, and DNA methylation levels. Our genome statistics far exceeded the...
Bordoni T, Dini FM, Morini M, Rinnovati R, Spadari A, Galuppi R.Mycetoma is a fungal chronic skin proliferative lesion rarely encountered in horses and often associated with fungi such as Scedosporium spp., Madurella spp., Phialophora spp., Curvularia spp., and less frequently with Aspergillus spp. A case of subcutaneous mycetoma in the cervical region in a 7-year-old male Quarter Horse, diagnosed through cytological, histological, cultural and molecular methods, is reported. Aspergillus nidulans, usually implicated in guttural pouch mycosis, was identified. This unusual case represents the second case report of mycetoma caused by Aspergillus nidulans in t...
MacNeill AL, Micheloud JF, Parvin R, Gjessing M, Airas NA, Sant'Ana FJF, Adamek M.Zoonotic poxviruses, including monkeypox virus (MPV), the causative agent for Mpox disease, have gained significant media and scientific attention due to recent outbreaks in human populations across the globe. The increase in human cases of poxvirus infection is not unexpected, as routine vaccination against smallpox (a disease caused by the poxvirus variola virus, which cross protects against other orthopoxviruses) was discontinued in the 1980s after its eradication. Large numbers of vertebrate and invertebrate species are susceptible to infection by . Clinical signs and histologic lesions ca...
Farchati H, Merlin A, Saussac M, Dornier X, Dhollande M, Garon D, Tapprest J, Sala C.Identifying and tracking equines are key activities in equine health prevention. France is one of the few European countries with an operational centralized database that records information on equines, owners, and keepers but not on the location and keeping conditions of equines. The objective of our study was to collect information on keeping habits of equines and the relative location of a wide range of equines, owners, and keepers and discuss their implication for surveillance and control of outbreak improvement. A national email survey was conducted among the 1.9% of people registered as ...
