Screenning of Chlamydia trachomatis Infection among Women Attending Outpatient Clinic of Infertility

Open Journal of Obstetrics and Gynecology 2015年第11期5卷 600-607页

作者： Heloisa Lopes Lavorato Natália Prearo Moco Laura Fernandes martin Ana Gabriela Pontes Santos Anaglória Pontes Marli Teresinha Cassamassimo Duarte Márcia Guimaraes da Silva Department of Gynecology and Obstetrics Botucatu Medical School Sao Paulo State University UNESP Botucatu Brazil Department of Pathology Botucatu Medical School Sao Paulo State University UNESP Botucatu Brazil Department of Gynecology and Obstetrics Botucatu Medical School Sao Paulo State University UNESP Botucatu Brazil Department of Nursing Botucatu Medical School Sao Paulo State University UNESP Botucatu Brazil

Objective: The goal of this study was to determine the prevalence of C. trachomatis in women diagnosed with infertility attending the Outpatient Clinic of Infertility from Botucatu Medical School, UNESP, Brazil. Patients and Methods: This molecular study enrolled a total of 112 women. Among these patients, 62 presented primary infertility while 50 presented secondary infertility. The criteria for eligibility included women who were: reproductive-aged;no prior report of seroconversion for HIV;no antibiotic or vaginal cream used in the preceding 30 days;and abstinence from sexual intercourse for 72 hours before the visit. The women were submitted to a gynecological examination and cervical samples were collected with an endocervical cytobrush for molecular analysis of C. trachomatis. Results: The prevalence of chlamydial infection was 8% with similar prevalence between primary (8.1%) and secondary (8.0%) infertility. Conclusion: Considering the asymptomatic nature of chlamydial infection and its association with tubal factor infertility, there is a pressing need to incorporate the screening of C. trachomatis infection as part of the routine investigation for infertility. The early diagnostic by screening can minimize complications and reduce Public Health costs with Assisted Reproductive Technology.

Genetic Stability of Cryopreserved Grapevine （Wtis vinifera L.） Genome by Vitrification Method

Journal of Agricultural Science and Technology(B) 2016年第6期6卷 380-386页

作者： Maria Femanda Lazo Javalera martin Ernesto Tiznado Hemandez Irasema Vargas Arispuro Miguel Angel martinez Tellez Maria Auxiliadora Islas Osuna Miguel Angel Hemandez Ofiate Marisela Rivera Dominguez Food Science Coordination Research Center for Food and Development Hermosillo Sonora 83000 Mexico Food Technology of Plant Origin Coordination Research Center for Food and Development Hermosillo Sonora 83000 Mexico

Grapevine （Vitis spp.） is an economically important fruit crop worldwide. In Mexico, Sonora State leads the table grape production and exportation to international markets. In this regard, it is important to preserve the grape varieties during long time without phenotypical or genotypical changes. Cryopreservation is a good alternative, although it very often can induce changes in genome and phenotype. In this study, grapevine cv. ＂Flame Seedless＂ axillary buds were cryoprcserved by vitrification using the plant vitrification solution 2 （PVS2） and stored in liquid nitrogen （LN） for one hour, one week and one month, respectively. Genetic stability of buds cryopreserved under all treatments was evaluated using inter-simple sequence repeats （ISSR） markers. Ten ISSR primers were evaluated, but only two primers were possible to amplify distinct and reproducible bands with sizes between 300 bp and 2,000 bp. Different ISSR fragment patterns were recorded in cryopreserved buds as compared with control. These results suggest that cryopreservation by LN and vitrification-cryopreservation affect genetic stability in grapevine.

Environmental Low Energy Gamma Rays Measurements in Brazilian Tropics Region During 2016

Journal of Environmental Science and Engineering(A) 2016年第11期5卷 559-565页

Low energy gamma radiation （0.2-10.0） MeV near the Earth＇s surface has several origins. Primary and secondary cosmic radiations with interactions of very high energy protons （〉 1 GeV） in terrestrial atmosphere are the main sources. The second most important source near the surface of the Earth and in the tropical and equatorial regions is the radon gas （Rn-222） that decays in alpha particles and gamma rays in this energy range. Also the telluric radionuclides 238U, 235U, 40K and 232Th in decays produce gamma radiation with different intensities at different locations on the surface of the Earth. Other sources less present are electrical discharges （lightning strikes） and man-made radioactive sources for medical, dental and industrial applications. In this work, it is shown that measurements of these components during all year 2016 are carried out at the ITA （Technological Institute of Aeronautics） campus in Sao Jose dos Campos, SP, Brazil and their possible correlations with atmospheric phenomena.

产业集群研究的一个重点就是探索集群存在的原因,西方学者倾向性地认为产业集群是竞争优势的重要来源。文章通过文献资料法和对比批判论证法对国外案例进行批判性分析来重新探讨西方主流观点的合理性。研究结果表明,功能性聚集和物理性聚集有着本质区别。以此为立足点来说明是否采用集群发展这个模式应该结合当地的具体实际情况来进行具体分析,切莫盲目模仿。

采用硅烷试剂对气相二氧化硅表面进行活化,并以此为载体固定N-乙酰基-L-半胱氨酸修饰的金纳米(NAC-金纳米)和酪氨酸酶,最后得到的复合物作为荧光探针,建立测定邻苯二酚的固体荧光猝灭分析方法。考察了各种实验条件对酪氨酸酶和NAC-金纳米固定到气相二氧化硅表面的影响,并对其进行优化。用荧光光谱仪对NAC-金纳米-酪氨酸酶-气相二氧化硅的固体荧光进行研究并加以应用。实验结果表明,随着通入不同浓度的邻苯二酚溶液,固体粉末的荧光被有效猝灭,基于此建立了测定邻苯二酚的固体荧光法。该方法的检出限为1.0×10-7mol/L,线性范围为5.0×10-7～4.0×10-4mol/L。

Introduction: Peripheral venous catheters (PVCs) are the most commonly used medical devices in hospitals for the administration of medications. Their use can lead to complications of varying severity. Objective: Determine the incidence and factors associated with the occurrence of PVC-related complications. Methods: This was a two-month prospective observational study conducted in the Medical Emergency Department (MED) of Yalgado Ouedraogo Teaching Hospital in Ouagadougou. All patients admitted during the study period who had a PVC inserted and removed were included in the study. Logistic regression analysis was used to identify the factors associated with the occurrence of complications. Results: In total, 459 PVCs were inserted and removed in 415 patients hospitalized at the Medical Emergency Department during the study period. The placement of 37.7% (n = 173) of PVCs resulted in complications in 131 patients (31.6%). For 644.3 days of catheterization, the incidence density was estimated at 6.5 complications per 1000 patient days. Phlebitis (24.0%), infection (5.7%), and accidental removal (2.8%) were the most frequently identified complications. The average age of the patients was 46.8 ± 18.9 years with a sex ratio of 1.22. The average patient hospitalization duration was 2.5 ± 2.6 days. In multivariate analysis, the factors significantly associated with the occurrence of complications after PVC insertion were patient’s state of agitation during the procedure (aOR = 12.59;95% CI = 4.12 - 38.49), placement of the PVC at the elbow bend (aOR = 2.17;95% CI = 1.86 - 5.52), multiple attempts
