OBJECTIVES: To describe the complications, short and long-term outcome and owner satisfaction of dogs with cranial cruciate ligament rupture treated with a recently described new osteotomy for the modified Maquet technique (N-MMT). MATERIALS AND METHODS: Medical records and radiographs of 82 dogs (84 stifles) were reviewed. Details regarding short-term outcome and complications were recorded from the medical records. Long-term follow-up information was obtained by telephone interview. Historical data and complications were statistically analysed. RESULTS: Major complications occurred in 34/84 stifles. Intra-operative complications occurred in 26/84 stifles, all of which were fissures or fractures of the cortical hinge. Twenty-one of these fractures or fissures were repaired with a figure-of-eight wire. The second most common major complication was late meniscal tears in 3/84 stifles. One dog sustained a complete tibial fracture. Non-displaced fracture of the cortical hinge was the most common postoperative minor complication, which occurred in 5/84 stifles. The median preoperative lameness score was 3 out of 6. Final in-hospital re-evaluation of limb function was available in 58 dogs. The median lameness score at that time was 0 out of 6. Development of osteotomy related complications was not associated with a significant change in the postoperative lameness score. CLINICAL SIGNIFICANCE: Subjectively assessed clinical outcome with the N-MMT was good to excellent in this cohort of dogs. However, a high rate of intra- and postoperative complications of the N-MMT procedure was also present in these dogs. [less ▲]

In Arabidopsis halleri, the AhHMA4 gene has an essential function in Zn/Cd hypertolerance and hyperaccumulation by mediating root to shoot translocation of metals. Constitutive high expression of AhHMA4 results from a tandem triplication and cis-activation of the promoter of all three copies. The three AhHMA4 copies possess divergent promoter sequences, but highly conserved coding sequences, and display identical expression profiles in the root and shoot vascular system. Here, we expressed an AhHMA4::GFP fusion under the control of each three A. halleri HMA4 promoters in a hma2hma4 double mutant of Arabidopsis thaliana to individually examine the function of each A. halleri AhHMA4 copy. The protein localized non-polarly at the plasma membrane of the root pericycle cells of both A. thaliana and A. halleri. The expression of each AhHMA4::GFP copy complemented the severe Zn deficiency phenotype of the hma2hma4 mutant by restoring root-to-shoot translocation of zinc. However, each copy had different impact on metal homeostasis in the A. thaliana genetic background: AhHMA4 copies 2 and 3 were more highly expressed and provided higher Zn tolerance in roots and accumulation in shoots than copy 1, whereas AhHMA4 copy 3 also increased Cd tolerance in roots. Our data suggest a certain extent of functional differentiation among the three A. halleri HMA4 copies, stemming from differences in expression levels rather than in expression profile. HMA4 is a key node of the Zn homeostasis network and small changes in expression level can have major impact on Zn allocation to root or shoot tissues. [less ▲]

This survey, conducted with 461 racehorse owners-breeders in Algeria between 2009 and 2011, investigates their perceptions, objectives and practices regarding selective breeding. Racehorse breeding is a full-time professional activity for a third of interviewees. The holdings are small-sized with 77% owning one or two mares. The regular practice of mating is here used to categorize breeders according to their degree of professionalization (38.4% professional vs. 61.6% occasional breeders). Experience in the sector was also used to classify breeders, considering as “junior” the breeders under 10 years experience (38.8%) and as “senior” those above 10 years (61.2%). More than professionalization, experience shows a significant impact on practices and objectives. Thus, experience influences breed choice (junior breeders tend to specialize while senior own both Arabian and Thoroughbreds), age at first foaling (sooner among senior breeders), information sources considered for selecting stallions (senior use more diversified sources), the importance granted to the price of mating (greater for junior breeders), the importance granted to the ranking compared to earnings (the ranking being more important to junior breeders), and the priority given to breeding (junior breeders give higher priority to a buy-race-resell activity). Finally, racehorse breeding is poorly professionalized, the only financial goal being cost coverage. Despite inappropriate practices, an interest for selection is noticed. [less ▲]

BACKGROUND: The pathogenesis of idiopathic pulmonary fibrosis (IPF) in dogs is poorly understood. In human, transforming growth factor beta1 (TGF-beta1) is considered central in the pathogenesis. OBJECTIVES: To investigate TGF-beta1 pathway in IPF. ANIMALS: Lung tissues from 12 affected and 11 control dogs. Serum from 16 affected West Highland white Terriers (WHWTs) and healthy dogs from predisposed (13 WHWTs, 12 Scottish Terriers and 13 Bichons Frise) and nonpredisposed breeds (10 Whippets, 10 Belgian shepherds, 8 Labradors). METHODS: In this prospective study, immunohistochemistry was used to evaluate expression and localization of TGF-beta1 protein and proteins involved in TGF-beta1 signaling (TGF-beta receptor type I and phospho-Smad2/3). Pulmonary expression of TGF-beta1 and molecules involved in its storage (latent TGF-beta binding proteins [LTBP] 1, 2, and 4), activation (alphanubeta6 and alphanubeta8 integrins, thrombospondin-1) and signal inhibition (Smad 7) was analyzed by quantitative reverse transcriptase PCR. Circulating TGF-beta1 concentration was measured by ELISA. RESULTS: In IPF, high level of TGF-beta1 protein was found in areas of fibrosis, epithelial cells had strong expression of TGF-beta receptor type 1 and phospho-Smad2/3, gene expression was decreased for LTBP 4 (P = .009) and beta8 integrin (P < .001) and increased for thrombospondin-1 (P = .016); no difference was seen for Smad7, LTBP1 and 2. Serum TGF-beta1 concentration was higher in predisposed compared with nonpredisposed breeds (P < .0001). CONCLUSIONS AND CLINICAL IMPORTANCE: This study identified an enhanced TGF-beta1 signaling activity in IPF. TGF-beta1 storage and activation proteins with altered expression represent potential therapeutic targets. Higher circulating TGF-beta1 concentration in predisposed breeds might partly explain their susceptibility for IPF [less ▲]

The objective of the present study was to compare Duroc (DU) and stress-negative Piétrain (PI) as terminal sires mated to F1(Large White x Mong Cai) sows (F1) on productivity, carcass characteristics, meat quality and meat chemical composition under household conditions in Hai Duong province, Vietnam. The reproduction performances were based on 74 litters of 42 F1 sows from 12 households and the semen from 11 Duroc and 10 Piétrain boars. Data on production and carcass traits were collected from 76 DUxF1and 67 PIxF1 crossbred fattening pigs. Longissimus dorsi samples from 55 and 37 of DUxF1 and PIxF1 respectively were analyzed to determine meat quality and meat chemical composition. The results show that household affected production, carcass, and meat quality traits (P<0.05) as well as reproduction (weights at birth and weaning, P<0.01). Inversely, boar breeds did not influence (P>0.06) on reproduction traits (except individual weight of born alive pigs and weaned pigs, P<0.01), production traits, meat chemical composition and meat quality (except pH at 4 days post mortem, P<0.05) while lean meat percentage of Piétrain-sired pigs was higher than those of Duroc-sired pigs (P<0.05). The utilization of Piétrain boars does not affect reproduction performances, growth rate and meat quality while improving lean meat percentage in comparison to Duroc boars. This suggests that the use of stress-negative Piétrain boars as terminal sires would improve lean meat percentage under household conditions in North Vietnam. [less ▲]

In humans, strenuous exercise causes increased susceptibility to respiratory infections associated with down-regulated expression of Toll-like receptors (TLRs), co-stimulatory and antigen-presenting molecules. Lower airway diseases are also a common problem in sport and racing horses. Because the innate immunity plays an essential role in lung defense mechanisms, we aimed to assess the effect of acute exercise and training on innate immune responses in two different compartments. Blood monocytes and pulmonary alveolar macrophages (PAM) were collected from horses in an untrained, moderately and intensively trained as well as deconditioned state before and after a strenuous exercise test (SET). The cells were analysed for TLR mRNA expression by real-time PCR in vitro and the cytokine production after in vitro stimulation with TLR ligands was measured by ELISA. Our results showed that training, but not acute exercise, modified the innate immune responses in both compartments. The mRNA expression of TLR3 was down-regulated by training in both cell types, whereas the expression of TLR4 was up-regulated in monocytes. Monocytes treated with lipopolysaccharide (LPS) and a synthetic diacylated lipoprotein (FSL) showed increased cytokine secretion in trained and deconditioned subjects indicating the activation of cells at the systemic level. The production of TNF-alpha and IFN-beta in non-stimulated and stimulated PAM was decreased in trained and deconditioned horses and might therefore explain the increased susceptibility to respiratory infections. Our study reports a dissociation between the systemic and the lung response to training that is probably implicated in the systemic inflammation and in the pulmonary susceptibility to infection.

Le cheptel caprin algérien est estimé à 3,8 millions de têtes dont 2,2 millions de femelles adultes. Comptant 400000 têtes, la race caprine kabyle représente un dixième du cheptel national. Afin de caractériser cette race et son élevage dans la région d’Ath Waghlis, une enquête a été menée auprès de 69 éleveurs (dont 22 femmes) de chèvres répartis sur les communes d’Akfadou, Chemini, Souk Oufella et Tibane. Les questionnaires portaient sur le profil socio-économique du ménage et ses activités agricoles, ainsi que les données techniques se rapportant à la production de chèvres. Il a également été procédé à la caractérisation morpho-biométrique des chèvres (18 mensurations corporelles, 3 variables qualitatives). L’analyse des structures d’élevage par classification hiérarchique ascendante (CHA) a permis de retenir quatre groupes d’élevages conservant 55,7% de la variabilité totale. Les variables considérées étaient le nombre d’animaux par espèce (chèvre, bovin, ovin, lapin, poule, dinde, ruches) et le nombre d’arbres (oliviers et figuiers) détenus. Le nombre moyen de chèvres pour chaque groupe est de 7,2±2,8, 11,1±3,5, 22,3±1,4 et 3,4±1,0. Le groupe 3, démontrant les plus grands effectifs caprins, est composé de personnes âgées en moyenne de 67 ans et ne pratiquant pas l’arboriculture. Ils possèdent également les plus importants effectifs d’ovins (48,67), de lapins (50,83), de poules (48,33) et de dindes (42). Le groupe 4, qui a les effectifs caprins les plus faibles, représente le groupe des jeunes éleveurs (moyenne ~39 ans), orientés vers l’élevage bovin (~52 têtes) et la production d’oliviers (~207 oliviers) et de figuiers (~47 figuiers). Les 18 variables morpho-biométriques étaient significativement plus élevées chez les mâles que chez les femelles (p<0,05). La chèvre kabyle est de petite taille (mâle : 68,23 cm vs femelle : 65,41 cm) et à poil long (mâle : 12 cm vs femelle 9 cm). Ses oreilles sont tombantes, le profil convexe à cassure nasale peu accentuée et sa robe va du brun foncé au noir. La riche diversité génétique des caprins locaux à Ath Waghlis souffre du manque de coordination des efforts de sélection des éleveurs, notamment du fait de l’absence de standard de la race et par l’introduction de races exotiques. Cette richesse devrait représenter un vivier utile où puiser les gènes d’intérêt pour la valorisation de la production locale, basée sur un engagement fort des éleveurs dans la production d’individus correspondant à un idéal collectivement déterminé.
