With the use of three human lung cultured cell lines: normal diploid fibroblasts (WI38), their SV40-transformants (VA13) and carcinoma cells (A549), whose doubling times were similar, the cytotoxicity of the protein antitumor antibiotics, auromomycin (AUR) and macromomycin (MCR), was studied by colony formation method. The susceptibilities of the three cell lines to these antibiotics were in th...
Additional chromosomal abnormalities are currently detected in Burkitt's lymphoma. They play major roles in the progression of BL and in prognosis. The genes involved remain elusive. A whole-genome oligonucleotide array CGH analysis correlated with karyotype and FISH was performed in a set of 27 Burkitt's lymphoma-derived cell lines and primary tumors. More than half of the 145 CNAs<2 Mb were m...
The purpose of this in vitro study was to compare the effect staining, glazing, and polishing on wear behavior stabilized zirconia with 5 mol% yttrium oxide (5Y-TZP) opposing 5Y-TZP, leucite-reinforced ceramic (LC), lithium disilicate (LD), microhybrid composite resin (MCR). Hemispheres 5Y-TZP were divided into six groups (n = 10) according finishing procedure: C (control), S (staining), G (gla...
Desorption electrospray ionisation (DESI) mass spectrometry images usually contain a large amount of information that can be difficult to interpret in an objective manner. We explore the use of imaging multivariate analysis (MVA) on DESI images of protein spots and rat brain sections to automatically assign peaks and improve discrimination of spatially important features. DESI parameters were o...
Previous studies have demonstrated enhanced insulin sensitivity in calorie-restricted [CR, fed 60% ad libitum (AL) one time daily] compared with AL-fed rats. To evaluate the effects of reduced food intake, independent of temporal differences in consumption, we studied AL (unlimited food access)-fed and CR (fed one time daily) rats along with groups temporally matched for feeding [fed 3 meals (M...
A nuclear power plant (NPP) is operated by operators in a main control room (MCR). Usually, the operators in an MCR consist of three to five operators and the number of operators is different according to the plant type. The operators always monitor the plant status and manipulate the control devices when necessary. The MCR operators perform a supervisory role of information gathering, planning...
OBJECTIVE To understand how the source of information affects different adverse event (AE) surveillance methods. DESIGN Retrospective analysis of inpatient adverse drug events (ADEs) and hospital-associated infections (HAIs) detected by either a computerized surveillance system (CSS) or manual chart review (MCR). MEASUREMENT Descriptive analysis of events detected using the two methods by t...
During a Brazilian multicentric antimicrobial resistance surveillance study, colistin resistance was investigated in 4,620 Enterobacteriaceae isolated from human, animal, food and environmental samples collected from 2000 to 2016. We present evidence that mcr-1-positive Escherichia coli has been emerging in South America since at least 2012, supporting a previous report on the possible acquisit...
در این پژوهش تفکیک منحنی چند متغیره- همزمان سازی براساس همبستگی بهینه شده (mcr-cow) برای تصحیح موثر جابه جایی زمان بازداری قبل از آنالیز های کروماتوگرافی پیشنهاد شده است. در این روش داده های کروماتوگرافی با آرایش مناسب با روش تفکیک منحنی چند متغیره- حداقل مربعات متناوب (mcr-als) و با اعمال محدودیت های مناسب آنالیز شده است. سپس جابه جایی زمان بازداری الگو های کروماتوگرافی بازیابی شده با روش cow ...
Colistin resistance was detected in 53 of 10,011 Escherichia coli (0.5%) by prospective phenotypic testing of consecutive clinical isolates in a single hospital in Barcelona, Spain (2012-15). The mcr-1 gene was retrospectively identified by PCR and sequencing in 15 of 50 available isolates. Each isolate had a unique PFGE pattern except for two. This clonal diversity supports the hypothesis of h...
