Microinjecting Cells Using a Constant-Flow Microinjection System

A method for bubble volume measurement under constant flow conditions in gas–liquid two-phase flow

Measuring the volume of a bubble, especially at its detachment, is a basic subject in gas-liquid two-phase flow research. A new indirect method for this measurement under constant flow conditions is presented. An electronic device is designed and constructed based on laser beam intensity. This device calculates the frequency of the bubble formation by measuring the total time of the formation p...

Nitric oxide administration using constant-flow ventilation.

Nitric oxide (NO) gas is known as both a vasodilator and a toxin. It can react with oxygen to form compounds more toxic than itself, such as nitrogen dioxide (NO2). The reactions are time dependent; thus, infusing NO into breathing circuits as close to ventilated subjects as possible may help minimize toxic byproduct exposure. Unfortunately, flow rates commonly used with mechanical ventilation ...

Information Panel Components of a Microinjection System

Direct-pressure microinjection with a micropipette is an essential tool for introducing a variety of impermeant substances into the cytoplasm or nucleus of plant and animal cells. Microinjection remains the most direct method to gain insight into the function and dynamics of intracellular components, to produce transgenic animals, or to overcome male infertility. This article describes the basi...

Intrathecal Morphine Therapy for Chronic Non-malignant Pain Using a Constant Flow Infusion System

Background: Implantable pumps for intrathecal opioid therapy in the last decades emerged as one of the most effective treatment for chronic non-malignant pain (CNMP) in selected patients. This study analyses reliability of intrathecal infusion morphine therapy for chronic and refractory pain not related to malignancy using an implantable constant flow pump. Methods: we studied eleven patients (...
