Fluorescence spectroscopy is entrenched throughout the life sciences today and is used for a variety of applications, including the detection of chemical or biological analytes/species, in reporting molecular events or for the understanding of microenvironments, such as local viscosity, polarity and voltage measurements, to name but just a few. In the majority of these fluorescencebased measure...

background: since embryonic stem (es) cells have the dual ability to proliferate indefinitely and differentiate into multiple tissue types, es cells could potentially provide an unlimited cell supply for human transplantation. objective: in order to study the differentiation of mouse embryonic stem (mes) cells, they were cultured in suspension by using es media without leukemia inhibitory facto...

Aynı sahneye ait iki ya da daha fazla düşük dinamik alana (LDR) sahip görüntülerden yüksek (HDR) tek bir görüntü elde etme yöntemlerine çoklu-pozlamalı birleştirme (MEF) denir. Bu çalışmada MEF için derin öğrenme (DL) modellerinden evrişimli sinir ağı (CNN) kullanan yeni yöntem önerilmiştir. Önerilen yöntemde ilk adımda CNN modeli kullanılarak kaynak haritası (fmap) edilmiştir. Birleştirilmiş g...

disc testing was used to determine antibiotic susceptibility and erythromycin resistance phenotypes. DNA from test samples was prepared by both Qiagen extraction and rapid boiling. As the efficiencies of the two methods were comparable, the rapid boiling method was used throughout. Primers were as published for erm(A), erm(B), erm(C), mef(A/E) 5 and erm(TR). 4 Donor and acceptor probe-pairs wer...

OBJECTIVE Piwil2, a member of Ago/Piwi gene family containing Piwi and PAZ domains, has been shown to be ectopically expressed in different cancer cells, especially its remarkable expression in cancer stem cells (CSCs), and is also known to be essential for germ line stem cell self-renewal in various organisms. The hypothesis that CSC may hold the key to the central problem of clinical oncology...

embryonic stem cells (escs) are originally derived from the icm of blastocysts and are characterized by their ability to self-renew and their pluripotencies. only a few reports have been published on esc isolations and line establishment in animals, even fewer in horses. however, it is still important to isolate equine escs for animal biotechnology and therapeutic applications. in the present s...

One hundred and twenty-four erythromycin-resistant pneumococcal isolates were examined for the presence of macrolide resistance genes. The erm(B) gene was detected in 118 (95.2%) isolates and the mef(A) gene in 83 (66.9%) isolates. Both the mef(A) and erm(B) genes were detected in 77 (62.1%) isolates. DNA macrorestriction analysis of these isolates identified them as belonging to a single multi...

Introduction Pectinolytic enzymes are of great importance for the clarification process “Vinho Verde” wine must, contributing to reduction haze development. During last decade, a growing body knowledge has been established about effects electric fields on activation important food enzymes. However, influence electrical parameters catalytic activity is enzyme-dependent and should be evaluated ca...
