RESUMO

The aim of this study was to evaluate the effects of adding different concentrations of edible bird's nest (EBN) which is secreted by swiftlet birds (Aerodramus fuciphagus), into EquiPlus® and E-Z Mixin® extenders on the quality of chilled Arabian stallion semen at various storage times (0, 24 and 48 h). Ten ejaculates were collected from five stallions, and diluted using the two extenders containing 0% (control), 0.12%, 0.24% and 0.24% of EBN + seminal plasma (SP). All the diluted semen samples were then cooled and stored at 5 °C, and examined at 0, 24 and 48 h. Sperm kinetic parameters were assessed using computer assisted sperm analysis (CASA) and viability were assessed using Hoechst33342/PI stain. In both extenders, total motility (TM) and progressive motility (PM) were significantly higher at 0.12% and 0.24% compared to 0.24% + SP at 24 and 48 h. At 0.12%, E-Z mixin® treated semen had significantly higher TM and PM than EquiPlus® at 24 and 48 h. At 0.12% and 0.24%, average path velocity (VAP), straight-line velocity (VSL) and curvilinear velocity (VCL) were significantly higher in E-Z mixin® treated semen compared to EquiPlus® at 24 and 48 h. Comparisons between the two extender types at different concentrations of EBN showed no significant difference in lateral head amplitude (ALH), linearity (LIN), straightness (STR), beat cross frequency (BCF) and viability, irrespective of the storage time. The percentage of viable was significantly higher in E-Z mixin® than EquiPlus® at 0 and 48 h in control and 0.12%. Supplementation of the E-Z mixin® extender with 0.12% and 0.24% EBN concentrations in the absence of SP provided better CASA parameters such as TM, PM, VAP, VSL, and VCL at 24 and 48 h storage time. In conclusion, the results of this study indicated that chilled semen from Arabian stallion that was extended using E-Z mixin® and supplemented with 0.12% and 0.24% EBN concentrations performed better and yielded superior results in sperm kinetic parameters and % viable compared to EquiPlus® at 24 and 48 h storage time.

RESUMO

Abstract This study aims to describe the causes of death in Arabian horses at Al Wathba, in Abu Dhabi (United Arab Emirates) during 2018-2019. This study was conducted in a cohort of all Arabian horses that died. Data was collected retrospectively and only those horses with a full necropsy report available were included in the study. The carcass and all internal organs of each horse were examined and representative samples of tissues with abnormalities were collected in 10% neutral buffered formalin and processed for histopathological examination. A descriptive statistical analysis was performed. A total of 25 Arabian horses were examined post-mortem. Out of them, 35% were females. In general, colic occurred specifically at a higher frequency (80%), cases of collapse and sudden death during exercise and races occurred in 8%, cases of perinatal death in 8% and one case of laminitis (4%). The annual mortality in relation to the estimated population was 1% approximately. In conclusion, we identified and described the causes of death in Arabian horses in Al Wathba, Abu Dhabi, UAE during the period 2018-2019. In summary, a pathology of the digestive system -specifically acute abdominal crisis (colic)- is the main cause of death in Arabian horses, with 80%; other causes of mortality with a low incidence were in order collapse and sudden death during exercise and races, perinatal death and laminitis. These results allow establishing risk prevention measures of mortality in horses for specific activities like handling, feeding, training and races.

Resumen El objetivo del presente estudio es describir las causas de muerte en caballos árabes en Al Wathba, en Abu Dhabi (Emiratos Árabes Unidos) durante el periodo 2018-2019. El presente estudio se hizo con una cohorte de todos los caballos árabes que murieron. Se recolectaron datos retrospectivamente y sólo se incluyeron en el estudio los caballos que tenían disponible un informe de necropsia completo. Los cadáveres y todos los órganos internos de cada caballo fueron examinados y se tomaron muestras representativas de tejidos con anormalidades, con una solución reguladora neutral de formalina al 10%, y fueron procesadas para su examen histopatológico. Se hizo un análisis estadístico descriptivo. Se examinaron en total 25 caballos árabes después de morir. De estos, el 35% eran yeguas. En general, el cólico ocurrió específicamente a una frecuencia más alta (80%), los casos de colapso y muerte repentina durante el ejercicio y las carreras ocurrieron en el 8%, los casos de muerte perinatal en el 8% y hubo un caso de laminitis (4%). La mortalidad anual en relación con la población estimada fue del 1% aproximadamente. En conclusión, identificamos y describimos las causas de muerte en los caballos árabes en Al Wathba, Abu Dhabi, EAU, durante el periodo de 2018-2019. En resumen, una patología del sistema digestivo -específicamente, la crisis abdominal aguda (cólico)- es la causa principal de muerte en caballos árabes, representando el 80%; otras causas de mortalidad con baja incidencia fueron, en su orden, el colapso y la muerte repentina durante el ejercicio y las carreras, la muerte perinatal y la laminitis. Estos resultados permiten establecer medidas de prevención del riesgo y de mortalidad en caballos para actividades específicas como su manejo, alimentación, entrenamiento y las carreras.

RESUMO

The alpheid genus Salmoneus Holthuis, 1955 is reported from Kuwait for the first time, with two species. One species, Salmoneus ikaros sp. nov., is described based on a single specimen from Failaka Island, extracted from the burrow of the callianassid ghost-shrimp Balsscallichirus masoomi (Tirmizi, 1970), together with the host. The new species is characterised by its peculiar eyes, which together with other characters separate it from all previously described species of Salmoneus. The second species, Salmoneus gracilipes Miya, 1972, is reported from Kuwait based on three specimens from two different localities and different habitats. Two specimens were found under coral rocks at a depth of about 7 m off Kubbar Island, whereas the third specimen was extracted from the burrow of the echiuran worm, Listriolobus cf. brevirostris Chen Yeh, 1958, at the type locality of S. ikaros sp. nov. at Failaka Island. Material identified as S. gracilipes from across its wide distribution range appears to be morphologically heterogeneous, possibly containing more than one species, and thus will need further studies.

RESUMO

The status of the common intertidal snapping shrimp, Alpheus inopinatus Holthuis Gottlieb, 1958, is discussed based on newly collected material from Kuwait. Alpheus inopinatus was previously confused with morphologically very similar species in the Alpheus lobidens De Haan, 1849 species complex, formerly identified as A. crassimanus Heller, 1862 and herein tentatively referred to as A. cf. lobidens. The material herein examined strongly supports the validity of A. inopinatus based on several morphological characters, as well as differences in the colour pattern, compared to other members of the A. lobidens complex.

RESUMO

Knowledge of the Arabian Gulf fishs parasite fauna is very poor. Until recently, only scattered reports from different locations are known for ecto- and endoparasites. Therefore, the present study aimed to investigate the digenean species that infects one of the most economically fish species in the Arabian Gulf, the rosy goatfish Parupeneus rubescens . One plagiorchiid species has been described, belonging to the Gorgoderidae family, and has been named as Phyllodistomum vaili Ho, Bray, Cutmore, Ward & Cribb, 2014 based on its morphological and morphometric characteristics. In order to accurately classify and characterize this plagiorchiid species, molecular analysis was carried out using both nuclear 18S and 28S rRNA gene regions and revealed that the present plagiorchiid species was associated with other species belonging to the Gorgoderidae family and deeply embedded in the Phyllodistomum genus, closely related to the previously described P. vaili (gb, KF013187.1, KF013173.1). The present study therefore revealed that the species Phyllodistomum is the first account as endoparasites from the rosy goatfish inhabiting the Arabian Gulf.(AU)

Portanto, o presente estudo teve como objetivo investigar as especies digenéticas que infectam uma das espécies economicamente mais importantes do Golfo Arábico, o peixe-cabra rosado Parupeneus rubescens . Uma espécie de plagiorquídeo foi descrita, pertencente à família Gorgoderidae e foi denominada Phyllodistomum vaili Ho, Bray, Cutmore, Ward & Cribb, 2014, com base em suas propriedades morfológicas e morfométricas. A fim de classificar e caracterizar com precisão essa espécie de plagiorquídeo, a análise molecular foi realizada usando as regiões nucleares do gene 18S e 28S rRNA, revelando que a atual espécie de plagiorchídeo estava associada a outras espécies pertencentes à família Gorgoderidae e, profundamente incorporada ao gênero Phyllodistomum , intimamente relacionado ao P. vaili descrito anteriormente (gb , KF013187.1, KF013173.1). O presente estudo revelou, portanto, que a espécie Phyllodistomum vailli é o primeiro relato como endoparasita do peixe-cabra rosado que habita o Golfo Arábico.(AU)

RESUMO

AIMS: Breast cancer within the region continues to present challenges to the healthcare services. Strategies to shed light on clinical gaps could better support country-specific circumstances. The aims of the mapping study were to identify the gaps in the evidence base, for the management of breast cancer with relevance to Bahrain and the Gulf Region. In parallel, focusing on areas and directions of research, which are compatible with international and local clinical interests. It was envisaged that the mapping project would expose not only opportunities to improve support to the community but also illustrate the possible engagement of a government entity and a Nongovernment Organization in a private-public partnership. METHOD: An extensive literature review of local and international publications from the period between 1979 and 2015 was undertaken. Searches were conducted using free-text terms, singularly or combined, with no limiters, to provide unrestricted retrieval of available English studies. RESULTS: A total of 326 citations were identified, which after deduplication provided 277 unique citations of which included 236 studies within 13 different categories, relevant to breast cancer within the Gulf Cooperation Council (GCC). CONCLUSION: Contextualizing gaps in literature and, therefore, providing evidence-based decisions, not only support the enduser, but better support the country-specific challenges and burdens to healthcare. Three broad but key areas were identified after mapping of the literature, covering:screening and mammography, knowledge translation and dissemination, and lymphoedema postsurgical resection. Similar mapping projects could be undertaken by other national NGO's to better support the government and solidify the framework for a public-private partnership.

RESUMO

This study aimed to determine and compare corneal sensitivity values in different regions of the cornea in five horse breeds. One hundred and forty five healthy horses, adults of both sexes, of the following breeds - Arabian horse (AH; n=20), Mangalarga Marchador (MM; n=50), Pure Blood Lusitano (PBL; n=35), Quarter Horse (QH; n=20), Brazilian Sport Horse (BSH; n=20)-were investigated. Corneal touch threshold (CTT) was measured with a Cochet-Bonnet esthesiometer in five different corneal regions. Measurements of the median central CTT were: 4.50±0.50cm (AH), 3.50±0.56cm (MM), 3.00±0.25cm (PBL), 2.50±0.44cm (QH) and 2.50±0.00cm (BSH). The central region was the most sensitive and the dorsal region the least sensitive corneal region for all breeds. CTT values differed for corneal regions and horse breeds. The CTT values were different among the corneal regions and the horse breeds. Arabian horses presented higher sensitivity values being the most sensitive in all of the corneal regions.

Objetivou-se com o presente estudo, determinar e comparar valores de sensibilidade corneana em diferentes regiões da córnea em cinco raças de equinos. Foram investigados 145 equinos hígidos, adultos de ambos os sexos, das raças: Puro Sangue Árabe (PSA; n=20), Mangalarga Marchador (MM; n=50), Puro Sangue Lusitano (PBL; n=35), Quarto de Milha (QH; n=20) e Brasileiro de Hipismo (BSH; n=20). O limiar táctil da córnea (LTC) foi mensurado com o auxílio do estesiômetro de Cochet-Bonnet, em cinco diferentes regiões da córnea (central, nasal, ventral, temporal e dorsal). Os valores médios das mensurações do LTC central foram: 4,50±0,50cm (PSA), 3,50±0,56cm (MM), 3,00±0,25cm (PSL), 2,50±0,44cm (QM) e 2,50±0,00cm (BH). A região central foi a mais sensível e a região dorsal a menos sensível para todas as raças. Os valores de LTC diferiram para as regiões da córnea e entre as raças dos cavalos, sendo a raça Puro Sangue Árabe o que apresentou valores maiores de sensibilidade, desta forma sendo o mais sensível em todas as regiões corneanas.

RESUMO

In this report, we record the rediscovery of Sanderia malayensis in Pakistani waters since the John Murray Expedition (193334) who collected two small specimens off-Karachi, Pakistan. The specimens were described and we discuss the shape of gastric pouches contour. We also comment upon the newly recorded Rhopilema nomadica jellyfish from the region, and assume it to be previously recorded as Rhopilema hispidum.

Esta nota registra a redescoberta de Sanderia malayensis em águas paquistanesas desde a Expedição John Murray (1933-34) que coletou dois pequenos exemplares na costa de Carachi. Os espécimes foram descritos e nós discutimos a forma do contorno das bolsas estomacais. Nós também comentamos sobre a medusa Rhopilema nomadica recentemente registrada para a região, e acreditamos tratar-se de uma espécie do gênero previamente registrada, Rhopilema hispidum.

RESUMO

The most frequently causes of gastric ulcers in horses are fasting, feeding type and management, as well as administration of certain medications. More recently, exercise has also been identified as an important factor in the development of gastric lesions in athlete horses. The purpose of the present study was to assess whether treadmill exercise predisposes the horses to the occurrence of gastric ulcers. Five Arabian horses underwent a twelve-week training period on a treadmill and a gastroscopic evaluation before and after the training period. All animals showed gastric lesions after the training period. Based on these results, it is concluded that Arabian horses undergoing exercise on a treadmill may develop gastric lesions varying in number and severity.(AU)

As causas mais frequentes de úlceras gástricas em cavalos são jejum, tipo de alimentação e manejo, bem como a administração de alguns medicamentos. Mais recentemente, o exercício também foi identificado como um fator importante no desenvolvimento das lesões gástricas em cavalos atletas. O objetivo do presente estudo foi avaliar se o exercício em esteira rolante predispõe os cavalos à ocorrência de úlceras gástricas. Cinco cavalos árabes foram submetidos a um período de doze semanas de treinamento em esteira rolante e a avaliação gastroscópica antes e após o período de treinamento. Todos os animais apresentaram lesões gástricas após o treinamento. Com base nesses resultados, conclui-se que cavalos árabes submetidos a exercício em esteira rolante podem desenvolver lesões gástricas em número e gravidade variados.(AU)

RESUMO

Evidence of cerebellar abiotrophy (CA) was found in a six-month-old Arabian filly with signs of incoordination, head tremor, wobbling, loss of balance and falling over, consistent with a cerebellar lesion. Normal hematology profile blood test and cerebrospinal fluid analysis excluded infectious encephalitis, and serological testing for Sarcocystis neurona was negative. The filly was euthanized. Postmortem X-ray radiography of the cervical cephalic region identified not abnormalities, discounting spinal trauma. The histopathological analysis of serial transverse cerebellar sections by electron microscopy revealed morphological characteristics of apoptotic cells with pyknotic nuclei and degenerate mitochondria, cytoplasmic condensation and areas with absence of Purkinje cells, matching with CA histopathological characteristics. The indirect DNA test for CA was positive in the filly, and DNA test confirmed the CA carrier state in the parents and the recessive inheritance of the disease. To our knowledge this is the first report of a CA case in Argentina.

RESUMO

Background: The Arabian leopard (Panthera paradus nimr) is the largest living felid in the arid Arabian Peninsula and classified on the IUCN red list as critically endangered. Unlike felids, neoplasia prevalence in canids such as benign lipoma and malignant liposarcoma has been long and well documented. Only until recently a plethora of reports emerged demonstrating that neoplasia occurrence in wild exotic felids is prevailed more than expected. Soft tissue tumors arise from fatty cells form either a benign lipoma or a dangerously malignant liposarcoma. Alarming though, such cellular transformation might endanger the life of an already endangered animal. Case: An intact Arabian male leopard living in captivity at the Oman wildlife animal breeding center (N23.70 E58.09 A5.80 m) aged approximately 18 years and weight 31 kg was admitted to the veterinary clinic for semen collection and routine physical examination. The animal was identified with two large adjacent subcutaneous masses on the upper rear left limb, clinically resembling that of a lipomatosis. Only one large tissue mass was surgically excised from the base with no incident of bleeding. Gross examination revealed a soft, smooth, rubbery, homogeneous, lack of internal fluid and whitish color lobule. Morphometry measurement of the mass shows that the weight, diameter, circumference, thickness and surface area were 3.6 gm...
