1Role of quorum sensing in bacterial infections显示文摘Quorum sensing(QS) is cell communication that is widely used by bacterial pathogens to coordinate the expression of several collective traits, including the production of multiple virulence factors, biofilm formation, and swarming motility once a population threshold is reached. Several lines of evidence indicate that QS enhances virulence of bacterial pathogens in animal models as well as in human infections; however, its relative importance for bacterial pathogenesis is still incomplete. In this review, we discuss the present evidence from in vitro and in vivo experiments in animal models, as well as from clinical studies, that link QS systems with human infections. We focus on two major QS bacterial models, the opportunistic Gram negative bacteria Pseudomonas aeruginosa and the Gram positive Staphylococcus aureus, which are also two of the main agents responsible of nosocomial and wound infections. In addition, QS communication systems in other bacterial, eukaryotic pathogens, and even immune and cancer cells are also reviewed, and finally, the new approaches proposed to combat bacterial infections by the attenuation of their QS communication systems and virulence are also discussed.Israel Castillo-Juárez Toshinari Maeda Edna Ayerim Mandujano-Tinoco María Tomás Berenice Pérez-Eretza Silvia Julieta García-Contreras Thomas K Wood Rodolfo García-Contreras 2015World Journal of Clinical Cases2015,3,7:15
2Chemical,Sensorial and Rheological Properties of a New Organic Rice Bran Beverage显示文摘Rice bran is a solid residue from rice polishing that is used in animal nutrition and rice oil production. Cultivation conditions with agro-toxics, lipids instability, and tendency for mycotoxin contamination restrict its application in human nutrition. Therefore, organic agriculture is an alternative to use the properties of rice bran. Rice bran beverage is a new cereal product from organic rice. This work presents the preliminary results of the chemical and rheological studies of a bath pasteurized rice bran beverage. Compared with integral defatted milk, soy extracts, and brown rice low-fat milk, the rice bran beverage studied in this work presents itself as an important source of minerals and unsaturated lipids. All essential amino acids were found in this product. Glutamic and aspartic acids were predominant. Bath pasteurization at boiling water temperature for 15 and 30 min was adequate for microbiological safety. Refrigeration storage for 20 days, evaluated by pH and acidity variations, was ideal for assessment of the beverage conservation time. The beverage viscosity was of the Newtonian standard behavior, and its viscosity during storage was not a good parameter to evaluate shelf life. Sensory preference tests showed positive perspectives for this new beverage.Gerson Luis FACCIN Leila do Nascimento VIEIRA Letícia Adélia MIOTTo Pedro Luiz Manique BARRETO Edna Regina AMANTE 2009Rice science2009,16,3:9
3Release of interleukin-10 and neurotrophic factors in the choroid plexus:possible inductors of neurogenesis following copolymer-1 immunization after cerebral ischemia显示文摘Copolymer-1(Cop-1) is a peptide with immunomodulatory properties, approved by the Food and Drug Administration of United States in the treatment of multiple sclerosis. Cop-1 has been shown to exert neuroprotective effects and induce neurogenesis in cerebral ischemia models. Nevertheless, the mechanism involved in the neurogenic action of this compound remains unknown. The choroid plexus(CP) is a network of cells that constitute the interphase between the immune and central nervous systems, with the ability to mediate neurogenesis through the release of cytokines and growth factors. Therefore, the CP could play a role in Cop-1-induced neurogenesis. In order to determine the participation of the CP in the induction of neurogenesis after Cop-1 immunization, we evaluated the gene expression of various growth factors(brain-derived neurotrophic factor, insulin-like growth factor 1, neurotrophin-3) and cytokines(tumor necrosis factor alpha, interferon-gamma, interleukin-4(IL-4), IL-10 and IL-17), in the CP at 14 days after ischemia. Furthermore, we analyzed the correlation between the expression of these genes and neurogenesis. Our results showed that Cop-1 was capable of stimulating an upregulation in the expression of the genes encoding for brain-derived neurotrophic factor, insulin-like growth factor 1, neurotrophin-3 and IL-10 in the CP, which correlated with an increase in neurogenesis in the subventricular and subgranular zone. As well, we observed a downregulation of IL-17 gene expression. This study demonstrates the effect of Cop-1 on the expression of growth factors and IL-10 in the CP, in the same way, presents a possible mechanism involved in the neurogenic effect of Cop-1.Yolanda Cruz Edna E.García Jessica V.Gálvez Stella V.Arias-Santiago Horacio G.Carvajal Raúl Silva-García Herlinda Bonilla-Jaime Julio Rojas-Castaneda Antonio Ibarra 2018Neural Regeneration Research2018,13,10:7
4Brain-derived neurotrophic factor plasma levels and premature cognitive impairment/dementia in type 2 diabetes显示文摘AIM To assess the relationship of brain-derived neurotrophic factor(BDNF) with cognitive impairment in patients with type 2 diabetes. METHODS The study included 40 patients with diabetes mellitus type 2(DM2), 37 patients with chronic kidney disease in hem dialysis hemodialysis therapy(HD) and 40 healthy subjects. BDNF in serum was quantified by ELISA. The Folstein Mini-Mental State Examination was used to evaluate cognitive impairment.RESULTS The patients with DM2 and the patients in HD were categorized into two groups, with cognitive impairment and without cognitive impairment. The levels of BDNF showed significant differences between patients with DM2(43.78 ± 9.05 vs 31.55 ± 10.24, P = 0.005). There were no differences between patients in HD(11.39 ± 8.87 vs 11.11 ± 10.64 P = 0.77); interestingly, ferritin levels were higher in patients with cognitive impairment(1564 ± 1335 vs 664 ± 484 P = 0.001). The comparison of BDNF values, using a Kruskal Wallis test, between patients with DM2, in HD and healthy controls showed statistical differences(P < 0.001).CONCLUSION Low levels of BDNF are associated with cognitive impairment in patients with DM2. The decrease of BDNF occurs early and progressively in patients in HD.Blanca Murillo Ortíz Joel Ramírez Emiliano Edna Ramos-Rodríguez Sandra Martínez-Garza Hilda Macías-Cervantes Sergio Solorio-Meza Texar Alfonso Pereyra-Nobara 2016World Journal of Diabetes2016,7,20:7
5围手术期患者的安全:正确的患者、正确的手术、正确的部位——一项多因素、跨部门的干预性研究显示文摘背景为围手术期患者提供安全的环境非常重要。基于这一点,我们在围手术期实施了“患者安全第一”的政策。方法在干预性研究的第一阶段(2001—2002年),我们首先制定并实施干预性研究中组织和教育方面的内容。2003至2005年为研究的实施阶段。根据我们的零忍受原则,在手术等候区内一旦发现患者的麻醉或手术准备工作中有重大差错,该患者就被送回病房(失败),并等到差错得到纠正后再进行手术。结果共有15856例患者参加了研究。在研究实施阶段的3年中,有112例患者被送回病房(0.71%)。与2003年的数据相比,2004年和2005年发生的重大错误明显减少,且有统计学意义(2003、2004和2005年的数据分别为1.04%、0.59%和0.49%)。而且,逐步逻辑回归方法分析结果显示,手术前准备不充分所致重大错误的发生率逐年下降,具有统计学意义(比值比=1.48,95%CI:1.16~1.87)。此外,在2003、2004和2005年中,各年的失败发生平均间隔时间分别为6.6、11.2和14.7天(P〈0.03)。最后,不仅患者手术前准备工作在研究期间有显著改善(P〈0.0001);而且,使患者手术前准备工作评分为100%的可能性也有明显增加(P〈0.001)。结论教育和提高认识能减少围手术期的错误发生率。但是,即使有详细规划的制度,也无法达到无差错的环境。因此,检查和全面分析应该持续不断地进行。Edna Zohar Yossi Noga Ehud Davidson Margalit Kantor Brian Fredman 周全红(译) 江伟(校) 2008麻醉与镇痛2008,4,4:5
6母牛安静发情鉴定技术概况及影响因素分析显示文摘安静发情母牛无明显发情行为,但具有正常卵泡发育、排卵过程,尚无理想的发情鉴定方法,常常错过人工输精最佳时机,导致产犊间隔延长,饲养成本增加。为此,本文综述了安静发情的鉴定方法概况及母牛安静发情的可能诱因。并指出,科学的管理及合理的营养可尽量减少母牛安静发情。此外,深入挖掘粪便、尿液、乳汁等发情标志物,研究其化合物在发情周期中的变化规律,并借助物联网、生物信息等技术,研发更精准、高效的发情鉴定技术,就有可能彻底突破安静发情鉴定技术瓶颈。周正义 田莉 田宏志 李茹意 段晨莹 OBIANWUNA Uchechukwu Edna 吕丽华 王栋 2021畜牧兽医学报2021,52,4:5
7Primary esophageal diffuse large B cell lymphoma presenting with tracheoesophageal fistula: A rare case and review显示文摘Primary non-Hodgkin lymphomas in the esophagus are rare. Tracheoesophageal fistulas mainly arise from solid esophageal carcinoma or mediastinal malignancies. Our patient presented with cough, dysphagia and weight loss, and upon initial computed tomography imaging and esophagogastroduodenoscopy, a malignant mass in the middle third of esophagus with tracheoesophageal fistula was found. The location of the mass and presence of malignant tracheoesophageal fistula were strongly suggestive of squamous cell carcinoma. However, tumor biopsy revealed diffuse large B-cell lymphoma. This case report details a rare incident of a primary diffuse large B-cell lymphoma presented as tracheoesophageal fistula and reviews previous literature.Jirapat Teerakanok Judy Park DeWitt Edna Juarez Kyaw Zin Thein Irfan Warraich 2017World Journal of Gastrointestinal Oncology2017,9,10:5
8Epidemiology of perforating peptic ulcer:A population-based retrospective study over 40 years显示文摘BACKGROUND The incidence of peptic ulcer disease has decreased during the last few decades,but the incidence of reported peptic ulcer complications has not decreased.Perforating peptic ulcer(PPU)is a severe form of the disease.AIM To assess trends in the incidence,presentation,and outcome of PPU over a period of 40 years.METHODS This was a single-centre,retrospective,cohort study of all patients admitted to Levanger Hospital,Norway,with PPU from 1978 to 2017.The patients were identified in the Patient Administrative System of the hospital using International Classification of Diseases(ICD),revision 8,ICD-9,and ICD-10 codes for perforated gastric and duodenal ulcers.We reviewed the medical records of the patients to retrieve data.Vital statistics were available for all patients.The incidence of PPU was analysed using Poisson regression with perforated ulcer as the dependent variable,and sex,age,and calendar year from 1978 to 2017 as covariates.Relative survival analysis was performed to compare long-term survival over the four decades.RESULTS Two hundred and nine patients were evaluated,including 113(54%)men.Fortysix(22%)patients were older than 80 years.Median age increased from the first to the last decade(from 63 to 72 years).The incidence rate increased with increasing age,but we measured a decline in recent decades for both sexes.A significant increase in the use of acetylsalicylic acid,from 5%(2/38)to 18%(8/45),was observed during the study period.Comorbidity increased significantly over the 40 years of the study,with 22%(10/45)of the patients having an American Society of Anaesthesiologists(ASA)score 4-5 in the last decade,compared to 5%(2/38)in the first decade.Thirty-nine percent(81/209)of the patients had one or more postoperative complications.Both 100-day mortality and long-term survival were associated with ASA score,without significant variations between the decades.CONCLUSION Declining incidence rates occurred in recent years,but the patients were older and had more comorbidity.The ASA score was associated with both short-term mortality and long-term survival.Aydin Dadfar Tom-Harald Edna 2020World Journal of Gastroenterology2020,26,35:5
9Short and long term neuro-behavioral alterations in type 1 diabetes mellitus pediatric population显示文摘Type 1 diabetes mellitus(T1DM) is one of the most prevalent chronic conditions affecting individuals under the age of 18 years, with increasing incidence worldwide, especially among very young age groups, younger than 5. There is still no cure for the disease, and therapeutic goals and guidelines are a challenge. Currently, despite T1 DM intensive management and technological interventions in therapy, the majority of pediatric patients do not achieve glycemic control goals. This leads to a potential prognosis of long term diabetic complications, nephrological, cardiac, ophthalmological and neurological. Unfortunately, the neurological manifestations, including neurocognitive and behavioral complications, may present soon after disease onset, during childhood and adolescence. These manifestations may be prominent, but at times subtle, thus they are often not reported by patients or physicians as related to the diabetes. Furthermore, the metabolic mechanism for such manifestations has been inconsistent and difficult to interpret in practical clinical care, as reported in several reviews on the topic of brain and T1 DM. However, new technological methods for brain assessment, as well as the introduction of continuous glucose monitoring, provide new insights and information regarding brain related manifestations and glycemic variability and control parameters, which may impact the clinical care of children and youth with T1 DM. This paper provides a comprehensive review of the most recently reported behavioral, cognitive domains, sleep related, electrophysiological, and structural alterations in children and adolescences from a novel point of view. The review focuses on reported impairments based on duration of T1 DM, its timeline, and modifiable disease related risk parameters. These findings are not without controversy, and limitations of data are presented in addition to recommendations for future research direction.Edna Litmanovitch Ronny Geva Marianna Rachmiel 2015World Journal of Diabetes2015,6,2:2
