Repetitive sequences are a conserved feature of many bacterial genomes. While first reported almost thirty years ago, and frequently exploited for genotyping purposes, little is known about their origin, maintenance, or processes affecting the dynamics of within-genome evolution. Here, beginning with analysis of the diversity and abundance of short oligonucleotide sequences in the genome of Pse...
In this paper I compare two well studied approaches to topological semantics| the domain-theoretic approach, exempli ed by the category of countably based equilogical spaces, Equ, and Type Two E ectivity, exempli ed by the category of Baire space representations, Rep(B ). These two categories are both locally cartesian closed extensions of countably based T0-spaces. A natural question to ask is...
1. Rep-tiling. This paper provides a short survey of recent work by the author on self-replicating tilings, a subject that has recently come under independent investigation by several mathematicians, for example Grr ochenig and Hass 11], Grr ochenig and Madyeh 10], Kenyon 14], Kitto, Vince and Wilson 15] and Vince 21] 22]. These tilings have application to computer addressing 5] 15] 20] and to ...
UNLABELLED Previous in vivo studies have suggested that nucleic acid polymers (NAPs) may reduce circulating levels of HBsAg in the blood by blocking its release from infected hepatocytes and that this effect may have clinical benefit. NAP treatment, was evaluated in two clinical studies in patients with HBeAg positive chronic HBV infection. The REP 101 study examined REP 2055 monotherapy in 8 p...
Breast cancer is the most prevalent malignancy in women throughout the world. Similar to other cancers, a strong relationship between breast cancer and environmental factors such as infectious agents has been reported. Toxoplasma gondii is a protozoan parasite which may play a role in cancer induction. The present study aimed to investigate a possible association between a history of T. gondii ...
زمینه و هدف : آسینتوباکتر بومانی [1] پاتوژنی گرم منفی است که ارتباط نزدیکی با انواعی از عفونتهای بیمارستانی ایجاد شده بویژه در بیماران بخش مراقبتهای ویژه دارد. این باکتری عمدتا عامل سپتیسمی ، نومونی و عفونت ادراری بیماران بستری شده در بیمارستان میباشد. در این مطالعه حساسیت آنتیبیوتیکی جدایههای آسینتوباکتر بومانی و الگوی تیپبندی مولکولی بوسیلهی PCR توالی های تکراری پالیندرومیک خارج ژنی...
A total of 119 Bacillus thuringiensis strains (83 type strains and 26 native isolates), as well as five B. cereus group species, were analyzed by repetitive extragenic palindromic sequence-based PCR analysis (Rep-PCR) fingerprinting. Primers Bc-REP-1 and Bc-REP-2 were specifically designed according to an extragenic 26-bp repeated sequence found in the six B. cereus group genomes reported. A to...
BACKGROUND The impact of nicorandil as adjunctive therapy for percutaneous coronary intervention (PCI) in patients with ST-elevation myocardial infarction (STEMI) is controversial. We performed 15O-labeled water positron emission tomography (PET) to quantify regional myocardial perfusion in patients with STEMI who received nicorandil or no adjunctive therapy during PCI. METHODS PCI was perfor...
