New double-staining technique for RNA and DNA measurement in marine phytoplankton

A new staining technique for polar bodies.

Introducing a combined Leishman-Giemsa stain as a new staining technique for avian blood smears

Background: The use of conventional stains including Giemsa, Wright and Leishman have become an essential tool for differential diagnosis of cells in peripheral blood. Aims: The aim of the study was to develop a new combination of Leishman-Giemsa (L&G;) stain for avian blood smears and to compare its efficacy with conventional staining methods. Methods:<...

Introducing a New and Simple Protocol for Capillary Electrophoresis of Cell Free Fetal Double Stranded DNA

Isolation of cell free fetal DNA (cffDNA) from maternal serum usually leads to very low concentrations of DNA impeding further resolving through conventional methods of electrophoresis. Although several protocols have been described for capillary electrophoresis (CE) of double stranded DNA, they usually need using special polymers or coated capillaries which degrade over time. Herein, we propos...

POLARIZATION HYSTERESIS CURVE MEASUREMENT FOR AN Au/PZT/YBCO DEVICE BY DOUBLE PULSE TECHNIQUE

Polarization for Au/Pb(Zr Ti )O /YBa Cu O ferroelectric capacitor has been studied and measured by pulse method. A sequence of pulses with amplitudes varying from 0 to 10 volts in 2 volt steps is applied and a conventional polarization curve is obtained by integrating the charge flow from the polarization switching induced by the voltage ramp. A value of 25?C/cm2 is measured for the satur...

Why marine phytoplankton calcify

Calcifying marine phytoplankton-coccolithophores- are some of the most successful yet enigmatic organisms in the ocean and are at risk from global change. To better understand how they will be affected, we need to know "why" coccolithophores calcify. We review coccolithophorid evolutionary history and cell biology as well as insights from recent experiments to provide a critical assessment of t...
