Distribution of anti-HAV IgM positivity according to age and months of a year in Van region,Turkey

Objectives: In this study we investigated the anti-HAVIgM positivity rates and their distribution according to ageand season of a year in Van region of Turkey.Materials and methods: During five-year period between2006-2010, the presence of anti-HAV IgM weredetermined in the serum samples sent to our laboratorythat have prediagnosis of hepatitis A by ELISA test, usingAxSYM (Abbott Diagnostics, Germany) and i2000SR Architect(Abbott Diagnostics, Germany) analyzers. For statisticalanalyze of Anti-HAV IgM positivity rates, patients’age and gender and time of year when specimen wasobtain were compared.Results: The presence of anti-HAV IgM was investigatedin a total of 8851 patients, including 5303 (60%) childrenand 3548 (40%) adults. Anti-HAV IgM in children and adultpatients were determined as 9.8% and 2.6%, respectively,and this difference was found statistically significant (p<0.01). Anti-HAV IgM positivity rate began to rise in August,reached the highest level in November-Decemberand decreased to the initial level in January. The highestfrequency detected during the November-December periodwas statistically significantly higher than rates foundduring other months.Conclusions: The prevalence of Hepatitis A was found tobe similar with previous studies performed in our country.The prevalence of disease was significantly increased especiallybetween November and December.Key words: Anti-HAV IgM, seasonal distribution, seroprevalence,ag

Antibiotics resistance of Stenotrophomonas maltophilia strains isolated from various clinical specimens

Background: A limited number of antibiotics are recommended for the therapy of Stenotrophomonas maltophilia infections due to therapy difficulties caused by its numerous mechanisms of resistance.Objectives: In this study conducted over a period of approximately 5 years we aimed to determine resistance rates of S. maltophilia based on drug classification recommended by Clinical and Laboratory Standards Institute.Methods: A total of 118 S. maltophilia strains isolated from various clinical specimens between January 2006 and June 2012 were included in the study. BD Phoenixautomated microbiology system (Becton Dickinson, USA) was utilized for species level identification and antibiotic susceptibility testing.Results: Sixty seven of S. maltophilia strains were isolated from tracheal aspirate isolates, 17 from blood, 10 from sputum, 10 from wound and 14 from other clinical specimens. Levofloxacin was found to be the most effective antibiotic against S. maltophilia strains with resistance rate of 7.6%. The resistance rates to other antibiotics were as follows: chloramphenicol 18.2%, trimethoprim-sulfamethoxazole 20.3% and ceftazidime 72%.Conclusion: The study revealed that S. maltophilia is resistant to many antibiotics. The treatment of infections caused by S. maltophilia should be preferred primarily as levofloxacin, chloramphenicol, and TMP-SXT, respectively.Keywords: Stenotrophomonas maltophilia, antibiotic, resistanc

Which Standards Are More Effective for Healthcare External Evaluation Organizations Management Systems?: ISQua 4th Ed. vs ISO 9004:2009

The aim of this study; to find out which standard for institutional accreditation is more appropriate for external evaluation organizations for healthcare institutions. Data obtained from ISQua: Guidelines and Standards for External Evaluation Organizations 4th Edition Version 1.2 and ISO: Managing for the sustained success of an organization – A quality management approach. In this study; two sets of standards that organizations can use as guide to increase their institutional quality were evaluated to find out which one is the best choice for External Evaluation Organizations for health care. Other quality systems and standard sets were not evaluated in this study. First, the ISO standard set was examined in detail, then it was sought whether there is a matching standard or requirement in the ISQua standard set with each standard found in the ISO standard set. It was evaluated whether the sets had superiority or weakness against each other. ISQua: Guidelines and Standards for External Evaluation Organizations were found as more suitable for external evaluation organizations for healthcare institutions

On pure Goldie dimensions

In this paper, we examine the pure Goldie dimension and dual pure Goldie dimension in finitely accessible additive categories. In particular, we show that if A is an object in a finitely accessible additive category A that has finite pure Goldie dimension n and finite dual pure Goldie dimension m, then EndA(A) is semilocal and the dual Goldie dimension of EndA(A) is less than or equal to n+m. © 2017 Taylor & Francis

Nane (Mentha piperita L.) distilasyonundan arta kalan hidrosolün kek üretiminde değerlendirilmesi

Nane esansiyel yağ ve fenolik bileşiklerce zengin tıbbi ve aromatik bir bitki olup esansiyel yağ elde edilmesinden sonra geriye kalan kısımlar değerlendirilememektedir. Bu çalışmada, tıbbi nane (M. piperita L.) hidrodistilasyonu sonrası arta kalan hidrosol kısmının kek üretiminde zenginleştirme amacıyla kullanılabilme potansiyeli incelenmiştir. Bu amaçla, fenolik bileşiklerce fakir olan kek, biyoaktif bileşiklerce zengin olan nane hidrosolü ile zenginleştirilmiş ve elde edilen keklerin fizikokimyasal ve duyusal analizleri gerçekleştirilmiştir. Nanenin 1 saatlik hidrodistilasyon işlemi sonrası elde edilen hidrosolden maltodekstrin ilave edilerek ve püskürtmeli kurutucu yardımıyla kurutularak kuru hidrosol ekstraktı (KHE) elde edilmiştir. KHE %0.5, %1 ve %1.5 (w/w) oranlarında kek formülasyonlarına eklenerek üretimler gerçekleştirilmiştir. Belirli oranlarda KHE içeren ve KHE içermeyen (kontrol) kek örneklerinin kuru madde, renk, toplam fenolik (TFMM), toplam flavonoid (TFM) ve antioksidan aktivite değerleri (DPPH ve ABTS) ile duyusal kabul edilebilirlikleri karşılaştırılmıştır. Ürünlere eklenen KHE miktarının artmasıyla TFMM, TFM ve antioksidan aktivite değerlerinde istatistiksel olarak anlamlı bir artışın (p&lt;0.05) olduğu saptanmıştır. KHE ile zenginleştirilen keklerin TFMM değerleri 13.60-34.03 mg GAE 100 g-1&nbsp;ve DPPH değerleri 21.94-60.75 mg TE 100 g-1&nbsp;tespit edilmiştir. Zenginleştirilmiş kek örneklerinin genel kabul edilebilirlik puanları yakın sonuçlar göstermiştir. Kurutulmuş hidrosolün keklere eklenmesi keklerin acılık ve burukluk değerlerinin yükselmesine neden olmuştur. Nane hidrosolünün bu çalışmada gösterildiği gibi kek formülasyonlarına ilave edilebileceği ve fenolik bileşiklerce fakir diğer işlenmiş ürünlere de ilave edilme potansiyelinin olduğu görünmektedir.</p

On complete pure-injectivity in locally finitely presented categories

Let C be a locally finitely presented additive category, and let E be a finitely presented pure-injective object of C. We prove that E has an indecomposable decomposition if and only if every pure epimorphic image of E is pure-injective if and only if the endomorphism ring of E is semiperfect. This extends a module-theoretic result which generalises the classical Osofsky Theorem
