Tight junctions are mainly formed by two types of proteins;claudins and occludin, both of which are fundamental to maintain the integrity and barrier function of the intestinal epithelium. This barrier function allows for the absorption of nutrients, mainly by transcytosis;however, in birds, 90% of the substances are absorbed by paracellular mechanisms. despite this, claudins present in the different parts of the intestinal tract of adult chickens are not known, much less their functional role. This study aimed to determine the presence of mRNA of claudins 1, 2, 3, 5, 10, 12, 16 and occludin, in the different regions of the intestine (duodenum, jejunum, ileum, cecum, and rectum) in chickens (Gallus gallus domesticus) through RT-PCR. To meet this goal, 7 weeks old roosters destined for slaughter and chicken embryos of 16 days of incubation (positive control) were used. For all the processed samples, amplicons of the expected size were obtained;claudin 1 (662 pb), claudin 2 (162 pb), claudin 3 (185 pb), claudin 5 (224 pb), claudin 10 (687 pb), claudin 12 (738 pb), claudin 16 (191 pb) and occludin (430 pb). To corroborate these findings, obtained amplicons were sequenced and, subsequently, a basic alignment was performed on the NCBI, obtaining a correlation of 100% with the original sequences in all analyzed samples. To our knowledge, the present work represents the first written report regarding the presence of mRNA of the main proteins involved in tight junction formation throughout the intestinal tract of domestic chickens of 7 weeks of age. These findings will allow elucidating the specific function of each of the reported proteins in the process of paracellular absorption in chickens.

背景:入院前处理中,在初始影像学检查前,严重创伤性脑损伤（TBI）均需要气管插管、镇静和机械通气。初始影像评估后,随即以早期的神经唤醒试验（ENWT）给予快速的神经学复评。这一管理策略给予了早期的参考临床检查,将与后续检查对比。目的 :本研究旨在描述经历过ENWT患者的临床特点,并明确ENWT失败的原因。方法 :我们进行了一项观察性的回顾性单中心研究,纳入创伤中心收治的所有TBI患者。ENWT是指在TBI后24小时内暂停镇静。研究数据涵盖了患者特点、CT扫描结果及患者转归,患者转归数据来自ICU收治的所有气管插管的TBI患者的预估。从患者档案中检索ENWT的特点和失败的原因。建立了多元Logistic回归模型,以确定ENWT失败的危险因素。结果 :7年中,所收治的242例气管插管TBI患者均纳入此研究。96例患者接受了ENWT,占患者总数的40%;其中38例（39.5%）患者中止了ENWT,主要原因是神经系统恶化（27例,71%）或呼吸窘迫（10例,26%）。ENWT失败的重要预测因子是:第1次影像检查显示硬膜下血肿厚度>5 mm（OR=3.2,95%CI为1.01;0.28）,以及初始GCS评分5 mm或初始GCS评分<5的患者,预期ENWT可能会失败。

Background: Malassezia pachydermatis is the main causative agent of canine otitis and also of a myriad of dermatological problems in companion animals;its interaction mechanisms with host cells are still unclear. Objectives: To establish an in vitro infection model of M. pachydermatis-exposed RK13 cells in order to evaluate cell morphological changes as well as changes in the structure of actin filaments. Methods: Cultures of RK13 cells were infected with M. pachydermatis, alterations caused by the yeast were evaluated by optical and fluorescence microscopy. Results: M. pachydermatis adheres itself to the cell and produces the formation of multiple agglomerates that cause changes in cell morphology, formation of cell aggregates in overlays, presence of syncytia and destruction of cell culture structure. The damaged cells presented changes in the actin filaments consisting of thickening of the cell cortex and loss of stress fibers. On the other hand, the formation of perinuclear actin rings in the yeasts was observed. Conclusions: An in vitro infection model was established with M. pachydermatis and alterations in cell morphology were observed consisting of changes in the structure of the actin filaments, overgrowth of the cells and the presence of syncytia.

Propolis is a natural substance made from resins collected from trees and plants, and which bees combine with pollen, wax, and their own enzymes. It has a complex chemical composition that varies with the harvest season, vegetation type, bee species, and geographical region. Thanks to its components, it has valuable biological properties such as antifungal, antibacterial, anticancer, antiviral, and immunomodulatory activity. For this study, a sample of propolis harvested in April 2019 was used, which came from a bee native to Mexico (Plebeia frontalis) in whose geographical environment there are seven other native species. Canine distemper virus is an RNA virus that causes a systemic infection with high fatality rates in guests without protective immunity. In this work, the antiviral effect of Plebeia frontalis propolis on canine distemper virus was tested, administering it one hour before and simultaneously to infection. The antiviral effect was evaluated by determining cellular viability with the MTT assay. The results obtained show that this propolis has a statistically significant antiviral effect on both treatments, although it is slightly better when applied one hour before viral infection, so we can recommend it as an antiviral treatment in both domestic animals and human beings. There are currently few studies of the antiviral effect of propolis, this being the first study of a melliponium propolis in veterinary medicine.

Objective: dehydroepiandrosterone (dHEA) has been previously reported to improve ovarian response in IVF for poor responders. Its effect remains uncertain. The purpose of this study was to evaluate the effect of dHEA given during two years in our unit, in order to build hypothesis for a future randomized controlled trial. design: Cohort of exposed and non-exposed dHEA study. Patient(s): 224 patients with AMH under 1.6 ng/ml undergoing IVF with a short antagonist protocol adding FSH and LH rec were enrolled for 327 IVF cycles. 176 patients had been treated with dHEA before IVF, and 151 had not. Intervention(s): None. Main Outcome Measure(s): Cancellation cycle rate, amount of gonadotrophins used, estradiol level on day six of stimulation, number of oocytes retrieved, metaphase II oocytes, blastocysts and frozen embryos, clinical pregnancy rate and miscarriage rate. Results: The cancellation rate was significantly higher in the group without dHEA (29.8% versus 13.1%, p = 0.002). The amount of gonadotrophins used for stimulation, the estradiol level on day six of stimulation, the number of oocytes retrieved, metaphase II oocytes, blastocysts, frozen embryos and miscarriage rate were not different in both groups. The clinical pregnancy rate per included patient in the dHEA group was 17.1% versus 8.6% in the non-treated group (p = 0.02). Conclusion: dHEA appears to improve clinical pregnancy rate by decreasing the cancellation rate.
