it is now generally recognized that anaerobic bacteria may be involved in most human bacterial infections that follow any form of surgery or are related to those body sites that have a large anaerobic population. anaerobes must therefore be sought in a wide variety of clinical specimens. in this study, 3015 specimens of patients (1684 male and 1331 female) with periodontitis (160 cases), abcess...

We derive dynamic optimal trading strategies that minimize the expected cost of trading a large block of equity over a fixed time horizon. Specifically, given a fixed block SM of shares to be executed within a fixed finite number of periods 1, and given a price-impact function that yields the execution price of an individual trade as a function of the shares traded and market conditions, we obt...

infections of the cerebrospinal shunts and other neurosurgical structures are not uncommon in the clinical practice. these infections are mostly clinical emergencies carrying negative prognostic impacts on the patients as well as spending healthcare resources. the low pathogenicity nature of some implicated pathogens results in minimal physical signs that may complicate the diagnosis and mislea...

an amplification polymerase chain reaction (pcr) test for the direct detection of chlamydia trachomatis in urethral and endocervical swab specimens from symptomatic and asymptomatic women and men were compared to standard culture technique. during 6 months, 300 endocervical swab specimens from 205 asymptomatic women (64.4%) and 95 symptomatic women (31.6%), and 187 urethral swab specimens from ...

cytomegalovirus is the most important pathogen affecting transplant recipients and causing significant morbidity and morbidity. the prevalence of cmv  infections in transplant recipient varies from country to country.  the aim of this study was to determine the prognostic value of pcr assay for cmv  detection in patients before keratoplasty.  a total of 23 patient samples enrolled in this study...

conclusions the prevalence of esbl-producing klebsiella strains in shahid-beheshti hospital in kashan has increased. the study concluded that there was a high prevalence of the blactx-m type gene among esbl positive isolates. patients and methods one hundred klebsiella spp. were isolated from clinical specimens of hospitalized patients at shahid-beheshti hospital from december 2012 to november ...

Block copolymers built on a dendritic block having fixed molecular weight but different number of peripheral PEG chains were synthesised. At a fixed block ratio, these block copolymers exhibited topological transition of cylindrical micelles depending on the number of PEG chains.

conclusions all the staphylococcus aureus strains and enterococcus faecium strains were sensitive to members of the oxazolidinone class of linezolid drug. development of multi drug resistance by gram positive bacteria constitutes a very serious challenge for medical practice. despite these rising rates, it is impossible to distinguish where they have originated from and special attention has th...
