Adventitious shoots were formed through callus on leaf explants of Eucalyptus camaldulensis Dehnh. (River red gum) taken from shoot cultures of mature trees. Callus formed in dark on a medium containing 1 g/l casein hydrolysate, 3 mg/l 1-naphthaleneacetic acid, 0.1 mg/l 6-benzyladenine and 50 g/l sucrose. Shoot initiation occurred in 4 weeks on calli(More)
A highly embryogenic culture ofEucalyptus citriodora was obtained by repetitive embryogenesis from somatic embryos cultured in the dark on a medium containing 500 mg/l each of glutamine and casein hydrolysate, 30 g/l of sucrose and 5 mg/l of 1-napthaleneacetic acid. Cultures retained morphogenetic ability for upto 36 months when maintained at 27°C by(More)
East Indian sandalwood (Santalum album L.) in commercial markets is highly prone to adulteration. A number of cases were registered with regard to the adulteration of East Indian sandalwood, but the lack of technical tools for the precise species identification of the source wood stalled most of the court cases. The standard DNA barcode regions, the rbcL,(More)
The aggregation and sedimentation kinetics of human erythrocytes was studied by modifying the cellular properties and medium compositions simultaneously. Dextrans of average molecular weight 70400 and 494000 were used to provide suspending medium modifications, while diamide (diazene dicarboxylic acid bis(N,N-dimethylamide)) was used to alter the membrane(More)
A method has been developed to study erythrocyte aggregation parameters based on He-Ne laser light scattering. Laser light is passed through a well mixed sample of blood and the forward scattered light intensity is recorded continuously. The orientation of erythrocytes, formation of aggregates and their sedimentation under the gravitational field produces a(More)
OBJECTIVES This study addressed the hypothesis that motion of the surface containing a regurgitant orifice relative to the Doppler ultrasound transducer can cause differences between actual flow rate and calculations based on the proximal flow convergence technique. BACKGROUND In vitro studies quantitating regurgitant flow rate by proximal flow(More)
The mechanism of erythrocyte aggregation has been studied in normal plasma, dextran 40 and dextran 70 suspensions in presence and absence of magnetic field at a concentration of 5 percent by laser light scattering. The inhomogeneous magnetic field enhances the aggregating tendency of normal erythrocytes. The growth of aggregates due to dextran 70 is(More)
The aggregation kinetics of erythrocytes is studied by using laser light scattering. Laser light is passed through a well mixed sample of blood and the forward-scattered light intensity is recorded continuously. During the process of aggregation and sedimentation under a gravitational field, erythrocytes are subjected to different orientations. The events(More)
An in vitro steady flow experiment was performed in order to test the accuracy of velocity measurements obtained through color Doppler flow mapping (CDFM). Using the American Society of Echocardiography (ASE) flow phantom, low (maximum velocity = 60 cm/sec), medium (maximum velocity = 300 cm/sec) and high (maximum velocity = 600 cm/sec) speed accelerating(More)
As haemorheological factors such as erythrocyte deformability and blood viscosity are important in maintaining normal blood circulation, these parameters were measured by Hemorheometer and Cone-Plate Microviscometer respectively. He-Ne laser light and photodiode detector assembly was used to study the optical characteristics of blood samples from normal(More)
