This pilot study reports the vertical transmission and reverse thermosensitivity of the MS-H vaccine strain of Mycoplasma synoviae (MS) by RAPD in commercial breeders and their progeny. At two weeks of age, breeders were vaccinated with the ts+ MS-H strain. At 9 weeks of age, an outbreak of infectious synovitis (IS) was detected in the progeny. Tracheal swab samples were collected from breeders at 24, 39, 48, and 70 weeks of age. At 9 weeks, pullets swab from the elbow joints were collected. RAPD was performed on the isolates at 39.5°C, and the same ts- MS-H strains were identified in the breeder hens and their progeny. Tracheal swabs from breeder hens were negative to MS isolation at 37°C and 39.5°C at 24- and 39-weeks. MS isolation was recovered from tracheal swabs from 9/10 and 10/10 breeders at 48- and 70- week. At 9 weeks of age in the progeny, MS was isolated from tracheal swabs of 10/10 from non-IS pullets. MS was isolated from 9/10 joints samples. The isolates from breeder hens and their progeny showed non-significant differences in five antimycoplasmic MIC100 values;otherwise, enrofloxacin presented a significant difference in MIC100 value (p < 0.05). This investigation demonstrated the reversal of the thermosensitivity, pathogenicity, and vertical transmission of the MS-H strain. Consequently, it is crucial to contemplate the danger of reversing pathogenicity and transmission to progeny when applying the MS-H vaccine strain.

背景与目的FMS样酪氨酸激酶3(FMS-like tyrosine kinase 3,FLT3)近膜结构域内的内部串联重复(internal tandem duplications,ITD)是急性髓系白血病(acute myeloid leukemia,AML)预后不良的指标。酪氨酸激酶抑制剂(如索拉非尼)是急性髓系白血病主要的靶向药物,但会产生耐药性,使其疗效受限。虽然目前已对FLT3抑制剂耐药的分子机制有所了解,但代谢物水平的细胞功能及与代谢通路的相互作用尚不清楚。本研究旨在阐明白血病细胞对FLT3抑制剂耐药后代谢组学的改变情况。方法我们建立了2株携带FLT3/ITD突变的索拉非尼耐药的细胞系,命名为鼠源BaF3/ITD-R和人源MV4-11-R细胞系。我们进行了非靶向代谢组学和稳定同位素标记代谢流分析,以确定与耐药相关的代谢改变。结果耐药细胞表现出完全改变的代谢图谱,其特征表现为葡萄糖需求增加,伴随进入磷酸戊糖途径(pentose phosphate pathway,PPP)的葡萄糖通量减少;氧化应激增加,同时谷胱甘肽合成增加。我们证明了耐药细胞中代谢改变得分最高的网络与核苷酸降解相关。我们还进行了稳定同位素示踪实验,结果提示在耐药细胞中进入PPP的葡萄糖通量减少。进一步研究表明,PPP中主要酶的抑制包括氧化途径的葡萄糖-6-磷酸脱氢酶(glucose-6-phosphate dehydrogenase,G6PD)缺陷和非氧化途径的转酮醇酶(transketolase,TKT)。此外,我们发现长期使用索拉非尼可导致FLT3/ITD阳性的白血病细胞氧化应激增加,同时伴有细胞增殖能力降低及抗氧化应答增强。结论我们通过比较代谢组学的相关数据鉴定出了独特的代谢和氧化还原适应特征,这可能促进了FLT3/ITD突变的白血病细胞发生索拉非尼耐药。

Hypersensitivity to Aspirin as a Factor for Poor Control in Hereditary Angioedema

引用

Journal of Biosciences and Medicines 2017年第3期5卷 39-54页

作者： Carlos Alberto garcia-Lopez Maria Eugenia Vargas-Camano Emmanuel Alcazar-Casarin guillermo Quintana Mexiac Pablo Leon Gomez Mario Alberto Ynga-Durand Benjamin Lopez-Velazquez Maria Isabel Castrejon-Vazquez Servicio Inmunologia Clinica y Alergia Centro Medico Nacional“20 de Noviembre”ISSSTEMexico CityMexico Laboratorio de Inmunidad de Mucosas Seccion de Investigacion y PosgradoEscuela Superior de MedicinaInstituto Politecnico NacionalMexico CityMexico

Background: Hereditary angioedema (HAE) is a primary immunodeficiency disorder characterized by C1 complement inhibitor deficiency and unregulated activation of complement. Aspirin hypersensitivity is related to an increase in the amount of leukotrienes with eosinophil and mast cell activation and increased levels of glandular kallikrein with upregulated local conversion of bradykinin. Both conditions can be present in the same patient. Objectives: We present five patients with HAE;they were all being treated in similar ways according to the therapeuthic options available in our institute (danazol). However, three of them had recurrent episodes of angioedema;in these cases, it was identified aspirin hypersensitivity as a cause of poor disease control. A review of the literature is included. Case Presentation: We present the cases of four females and one male (age range 21 - 58 years) with type I HAE. Subjects were all ISSSTE beneficiaries (state workers) treated at the National Medical Center “20 de Noviembre”. Aspirin hypersensitivity was identified in three patients. Elimination of NSAIDs along with dietary elimination of high salicylate-containing foods improved control of angioedema crisis (severe and/ or recurrent episodes). Discussion: Aspirin hypersensitivity was identified as a factor for poor control in our patients with HAE. Such cases improved with dietary elimination of high salicylate-containing foods and avoidance of NSAIDs. Conclusions: This is the first report of patients with HAE and aspirin hypersensitivity as a cause of poor control. We recommend a deliberate search of these comorbidities, especially in cases of poor disease control. Further studies are needed to continue the investigation on this topic.

The genetic diversity and structure of 72 Appaloosa horses belonging to a closed breeding population from an ecological reserve in Buenos Aires,Argentina,was investigated using eight microsatellite markers from the International Society for Animal Genetics *** data showed that this Appaloosa horse population had an elevated degree of genetic diversity(He=0.746)and did not present a significant increase of homozygous individuals(F_(IS-0)).However,the short tandem repeats,AHT5,ASB2,HTG10 and VHL20,were not in Hardy-Weinberg equilibrium(P-value<0.05).Genetic relationships between this population and other well known horse breeds showed that Appaloosa horses from Argentina could have had their origin in the horses of the Nez Perce’s people in Idaho while other Appaloosa horses may have had influences from Andalusian and Lusitano *** closed breeding population conserves an important degree of Appaloosa genetic diversity and notwithstanding its particular breeding characteristics,represents a valuable genetic resource for conservation.

Essential Oils as an Alternative to Antibiotics to Reduce the Incidence and Severity of Necrotic Enteritis in Broiler Chickens: A Short Review

Shehata guillermo Tellez-Isaias Department of Poultry Science University of Arkansas Agricultural Experiment Station Fayetteville USA Facultad de Estudios Superiores Cuautitlan Universidad Nacional Autonoma de Mexico (UNAM) Cuautitlan Izcalli Estado de Mexico Mexico Departamento de Medicina y Zootecnia de Aves Facultad de Medicina Veterinaria y Zootecnia (FMVZ) UNAM Cd. de Mexico Mexico Programa de Maestría y Doctorado en Ciencias de la Producción y de la Salud Animal FMVZ UNAM Cd. de Mexico Mexico College of Life Science and Engineering Foshan University Foshan China Prophy-Institute for Applied Prophylaxis Bönen Germany

Due to the removal of antibiotic growth promoters (AGPs) and consumer pressure for antibiotic-free (ABF) or no antibiotics ever (NAE) poultry production, there is a need for sustainable alternatives to prevent disease in commercial poultry operations. Without AGPs, there has been a rise in diseases that were traditionally controlled by subtherapeutic levels of antibiotics in the diet. This has impacted the health of commercial poultry and has been a significant cost to poultry producers. To mitigate this, the industry has started to investigate alternatives to antibiotics to treat these forthcoming health issues, such as necrotic enteritis (NE). NE is an enteric disease caused by an over proliferation of toxigenic Clostridium perfringens (CP) in the gastrointestinal tract. Although CP is a commensal in the avian intestinal tract, dysbiosis caused by inflammation and impaired intestinal integrity facilitates uncontrolled replication of CP. Infectious agents, such as Eimeria maxima, appear to be a predominant predisposing factor that promotes NE. However, non-infectious stressors, including dietary changes, have also been associated with NE to some degree. As a result of increased pressure to restrict the use of antibiotics, there is a need for research evaluating the efficacy of alternatives, such as plant-derived essential oils, as potential tools to mitigate NE in commercial poultry flocks. The aim of this study is to review the effects of essential oils as an alternative to antibiotics to reduce the incidence and severity of necrotic enteritis in broiler chickens.

Clinical and prognostic implications of atrial fibrillation in patients undergoing transcatheter aortic valve implantation

引用

World Journal of Cardiology 2012年第1期4卷 8-14页

作者： Pablo Salinas Raúl Moreno Luis Calvo Santiago Jiménez-Valero guillermo Galeote Angel Sánchez-Recalde Teresa López-Fernández Sergio garcia-Blas Diego Iglesias Luis Riera Isidro Moreno-Gómez Jose María Mesa Ignacio Plaza Rocio Ayala Rosa Gonzalez José-Luis López-Sendón Division of Interventional Cardiology University Hospital La Paz Unit of Echocardiography University Hospital La Paz Department of Cardiology University Hospital La Paz Vascular Surgery University Hospital La Paz Department of Cardiac Anaesthesia University Hospital La Paz Cardiac Surgery University Hospital La Paz Department of Cardiology Hospital Infanta Sofia Department of Cardiology Hospital de la Cruz Roja

AIM: To study a cohort of consecutive patients under-going transcatheter aortic valve implantation (TAVI) and compare the outcomes of atrial fibrillation (AF) patients vs patients in sinus rhythm (SR). METHODS: All consecutive patients undergoing TAVI in our hospital were included. The AF group comprised patients in AF at the time of TAVI or with history of AF, and were compared with the SR group. Procedural, echocardiographic and follow-up variables were compared. Likewise, the CHA 2 DS 2-VASC stroke risk score and HAS-BLED bleeding risk score and antithrombotic treatment at discharge in AF patients were compared with that in SR patients. RESULTS: From a total of 34 patients undergoing TAVI, 17 (50%) were allocated to the AF group, of whom 15 (88%) were under chronic oral anticoagulation. Patients in the AF group were similar to those in the SR group except for a trend (P = 0.07) for a higher logistic EuroSCORE (28% vs 19%), and a higher prevalence of hypertension (82% vs 53%) and chronic renal failure (17% vs 0%). Risk of both stroke and bleeding was high in the AF group (mean CHA 2 DS 2-VASC 4.3, mean HAS-BLED 2.9). In the AF group, treatment at discharge included chronic oral anticoagulation in all except one case, and in association with an antiplatelet drug in 57% of patients. During a mean follow-up of 11 mo (maximum 32), there were only two strokes, none of them during the peri-procedural period: one in the AF group at 30 mo and one in the SR group at 3 mo. There were no statistical differences in procedural success, and clinical outcome (survival at 1 year 81% vs 74% in AF and SR groups, respectively, P = NS). CONCLUSION: Patients in AF undergoing TAVI show a trend to a higher surgical risk. However, in our cohort, patients in AF did not have a higher stroke rate compared to the SR group, and the prognosis was similar in both groups.
