Our aim is to provide a look into the typical clinical caseload from odontology primary care, based on dogs and cats treated at a veterinary teaching hospital. From 2013 to 2019, 468 dogs and 139 ...cats were treated. Data come from primary care practice; no referral cases were considered. The most frequently detected conditions in dogs were periodontal disease (59.6%), oral tumors (11.3%), dental fractures (7.7%), class 1 malocclusion (7.1%), dental fistulas (5.8%), class 3 malocclusion (3.4%), gingivitis (1.7%), periodontal disease with tooth resorption (0.4%), class 2 malocclusion (0.2%) and others (2.8%). Different distributions of main conditions were found when considering age and weight/breed (p<0.001). In cats, the main conditions were periodontal disease (30.9%), periodontal disease with tooth resorption (23.0%), tooth resorption (12.2%), gingivostomatitis (10.8%), gingivostomatitis with tooth resorption (7.2%), oral tumors (7.2%) and others (8.6%). When considering age, different distributions of main conditions were found (p<0.001). In dogs and cats, both sexes showed similar distributions of main conditions (p>0.05). No significant temporal trends were detected. These prevalence estimations can be useful in the diagnosis and establishment of preventive measures. Attention could be focused on different oral conditions depending on breed (dogs) and on age (both dogs and cats).
L’objectif de cette étude est d’étudier rétrospectivement les soins dentaires apportés aux chats et aux chiens en première intention traités dans un hôpital universitaire vétérinaire. Les affections le plus fréquemment diagnostiquées chez le chien sont la maladie parodontale (59,6 %), les tumeurs buccales (11,3 %), les fractures dentaires (7,7 %), les malocclusions de classe 1 (7,1 %), les fistules dentaires (5,8 %), les malocclusions de classe 3 (3,4 %), la gingivite (1,7 %), la maladie parodontale avec résorption dentaire (0,4 %), les malocclusions de classe 2 (0,2 %) et d’autres entités à hauteur de 2,8 %. L’âge, le poids et la race des patients modifient significativement la prévalence des maladies mentionnées ci-dessus (p<0,001). Chez le chat, les diagnostics les plus fréquents sont la maladie parodontale (30,9 %), la maladie parodontale avec résorption dentaire (23,0 %), la résorption dentaire (12,2 %), la gingivostomatite (10,8 %), la résorption dentaire avec gingivostomatite (7,2 %), les tumeurs buccales (7,2 %) et d’autres entités à hauteur de 8,6 %. Dans l’espèce féline, seul l’âge des patients modifie significativement les prévalences des différentes maladies (p<0,001). En revanche, le sexe des patients n’a aucun impact significatif sur la prévalence des principales maladies dans les deux espèces (p>0,05), et, et aucune tendance significative n’a été détectée dans le temps. Ces estimations de prévalence peuvent être utiles dans le diagnostic et la mise en place de mesures préventives. Une attention particulière pourrait être apportée aux différentes affections buccodentaires en fonction de la race chez le chien, de l’âge chez le chien et le chat.
The aim of the present work is to estimate the usefulness of microsatellite genetic markers analysis to characterize and analyze the possible differences between a captive reared population and a ...wild one from the same species. The first sample consists of 27 chukar partridges (Alectoris chukar) bred in one farm in Argentina. The second one is composed of 31 chukar partridges coming from a wild Cyprus population (A. chukar cypriotes). We analyzed seven microsatellite loci: MCW135, MCW225, MCW276, MCW280, MCW295, LEI31, and ADL0142. The Argentina group showed higher genetic variation than the Cyprus did. Significant global F IS value was found in the Argentina sample. Significant genetic differentiation exists between both groups (F ST=0.394; p<0.01). The Argentina group did not show any signs of bottleneck. Results from Factorial Correspondence Analysis (FCA) suggest that the 58 partridges could be split into two distinct genetic clusters (Cyprus and Argentina). Nevertheless, in the light of PARTITION results, three Argentina individuals might be related to Cyprus. STRUCTURE is unable to assign these three animals to any of the two groups. This could be due to a single or repeated introduction of external individuals into the original Argentina group, so that these results would point to more than one origin for this population. This admixture of individuals could explain the high genetic variation observed in the Argentina farm. Global F IS value would probably be higher without these immigrations; on the other hand, these admixtures could have prevented bottlenecks.
Context. Open clusters are key to studying the formation and evolution of the Galactic disc. However, there is a deficiency of radial velocity and chemical abundance determinations for open clusters ...in the literature. Aims. We intend to increase the number of determinations of radial velocities and metallicities from spectroscopy for open clusters. Methods. We acquired medium-resolution spectra (R ~ 8000) in the infrared region Ca ii triplet lines (~8500 Å) for several stars in five open clusters with the long-slit IDS spectrograph on the 2.5 m Isaac Newton Telescope (Roque de los Muchachos Observatory, Spain). Radial velocities were obtained by cross-correlation fitting techniques. The relationships available in the literature between the strength of infrared Ca ii lines and metallicity were also used to derive the metallicity for each cluster. Results. We obtain ⟨Vr⟩ = 48.6 ± 3.4, −58.4 ± 6.8, 26.0 ± 4.3, and −65.3 ± 3.2 km s-1 for Berkeley 23, NGC 559, NGC 6603, and NGC 7245, respectively. We found Fe/H = −0.25 ± 0.14 and −0.15 ± 0.18 for NGC 559 and NGC 7245, respectively. Berkeley 23 has low metallicity, Fe/H = −0.42 ± 0.13, which is similar to other open clusters in the outskirts of the Galactic disc. In contrast, we derived high metallicity ( Fe/H = +0.43 ± 0.15) for NGC 6603, which places this system among the most metal-rich known open clusters. To our knowledge, this is the first determination of radial velocities and metallicities from spectroscopy for these clusters, except NGC 6603, for which radial velocities had been previously determined. We have also analysed ten stars in the line of sight to King 1. Because of the large dispersion obtained in both radial velocity and metallicity, we cannot be sure that we have sampled true cluster members.
Home non-invasive ventilation (NIV) is recommended in patients with COPD and hypercapnic chronic respiratory failure (HCRF). The mechanism by it can improve alveolar ventilation during spontaneous ...breathing is not yet completely explained. Our aim is to evaluate the impact of on diaphragm muscle function in a series of patients with HCRF.
Observational, longitudinal, prospective study of a series of patients with very severe chronic obstruction to airflow treated with home high imntensity NIV (HINIV). Patients underwent a baseline and after 12 months assessment including adherence to treatment, quality of life, respiratory function tests and diaphragmatic ultrasound. SPSS v.26 software was used for statistical analysis.
We studied 30 patients, 63% male, the mean age was 60.8 (±6.4) years old. Patients had a severe obstructive ventilatory pattern FEV1 21.8 (±6.1)% and hypercapnia pCO2 56.4 (±7.2) mmHg. After 12 months of HINIV, we observed significant increases in FVC of 9.2% (p = 0.002), FEV1 of 3.5% (p = 0.04), MIP of 9.4% (p = 0.006), and 6-minute-walking test (6MWT) of 31.9 m (p = 0.001), as well as decreases in paCO2 of 12.5 mmHg (p = 0.001), HCO3 of 4.7 mmol/L (p = 0.001) and BODE index from 7 to 6. Diaphragmatic ultrasound demonstrated an increase in the thickening fraction of 14% (p = 0.002). Respiratory symptoms (p = 0.04), physical function (p = 0.03), and sleep (p = 0.04) also improved.
In patients with HCRF due to very severe chronic obstruction to airflow, long-term HINIV can improve respiratory performance by improving the function of the diaphragmatic musculature. Larger multicenter clinical trials are needed to confirm the results suggested in this study.
For the first time, microsatellite loci were used to study the genetic structure in Alectoris chukar cypriotes. Four of the ten tested microsatellite loci were found to be polymorphic in 33 ...individuals from four regions of Cyprus. The differentiation test between all the pairs of samples gave non-differentiation exact P values in every case (P>0.05). The posterior probability distribution on the number of source populations indicated only one population (P=0.977); also, a high Bayes factor value (130.020) was obtained. Posterior co-assignment probabilities (measures of similarity) for all pairs of individuals ranged from 0.984 to 1. The global FIS value was not found to be significant. A recent bottleneck of the Cypriot total partridge population is suggested and this is supported by a significant Wilcoxon test (P=0.031) under the Infinite Alleles Model (IAM) and shifted mode in the alleles frequencies distribution. The results suggest that all the individuals studied belong to only one randomly mating (panmictic) population, with low genetic variation and evidence of recent effective population size reduction (genetic bottleneck). A big hunting pressure exists on the island and about 200,000 captive-bred birds are released every year; these individuals are descendant from a small number of eggs collected in a small area of Cyprus in 1986 and this founder effect could explain the existence of a bottleneck and the low genetic variability.
The present report concerns our attempts to further study the effect of quinolone coccidiostats on the sporulation of
Eimeria tenella oocysts by analyzing the meiotic behaviour of the chromosomes. To ...that end, synaptonemal complexes were analyzed by TEM applied to intact meiotic chromosomes. These were isolated after disruption of oocysts, which were harvested from decoquinate-medicated and non-medicated (control) birds. In oocysts from control birds, synaptonemal complexes appeared as the 14 bivalents of the normal karyotype. However, in oocysts from medicated birds, our synaptonemal complex analysis revealed a reciprocal translocation, which was observed as an irregular pairing of chromosome axes 5 and 12 resulting in quadrivalent and trivalent configurations. This finding suggests breakage points in chromosomes 5 and 12 and exchange of chromosomal segments. Furthermore, breakpoints in chromosome 12 resulted in telomere deletion. The chromosomal aberrations described in the present study may result in reduced sporulation since chromosomes involved in translocations segregate abnormally during meiosis. In addition, the results reported provide new evidence of the inhibitory effect of quinolones on the sporulation of
E. tenella oocysts, since sporocysts were not formed.

Este estudio pretendió conocer la situación de la formación inicial (FI) y las perspectivas de establecer un perfil de competencias en la formación de profesionales de actividad física adaptada ...(AFA). Desde una perspectiva interpretativa, se utilizó la entrevista y la observación no participante. Participaron siete reconocidos expertos en AFA y FI, vinculados con la universidad, y se asistió a un encuentro nacional de expertos que debatían temas vinculados al propósito del estudio. Los discursos de los expertos fueron analizados en su contenido, con la orientación de las categorías definidas previamente. Dicho análisis permite concluir que los juicios de valor sobre la FI están mediatizados por las percepciones de realidades concretas. Los expertos identifican elementos básicos para un perfil de competencias, con un fuerte componente actitudinal, aunque se detecta falta de concreción sobre cuáles serían todos los ingredientes fundamentales de un perfil competencial del docente de EF que enseña AFA.
