Pixel dislocation correction method for a laser confocal scanning microscope through the nonlinear triangular wave driving mode and square wave index reconstruction.

The reciprocate scanning scheme of two-dimensional galvanometers is widely used in laser confocal scanning microscopes with high speed. However, the equal interval acquisition of an analog digital acquisition card (AD) and the unequal change of the galvanometer's scanning speed will cause the dislocation of pixels and distortion of the reconstructed image. Meanwhile, the movement properties of the galvanometers in the edge of the scanning area are complex, which will increase the difficulty of segmenting the collected one-dimensional data stream the AD collected into row data of a two-dimensional reconstructed image.

Enhanced disease resistance and drought tolerance in transgenic rice plants overexpressing protein elicitors from Magnaporthe oryzae.

Exogenous application of the protein elicitors MoHrip1 and MoHrip2, which were isolated from the pathogenic fungus Magnaporthe oryzae (M. oryzae), was previously shown to induce a hypersensitive response in tobacco and to enhance resistance to rice blast. In this work, we successfully transformed rice with the mohrip1 and mohrip2 genes separately.

A novel elicitor identified from Magnaporthe oryzae triggers defense responses in tobacco and rice.

Our studies indicate a potential important elicitor candidate which can aid in the fight against a worldwide disease, rice blast. In this study, we report the purification, identification, characterization, and gene cloning of a novel hypersensitive response-inducing protein elicitor (MoHrip2) secreted from an important pathogenic fungus, Magnaporthe oryzae. The protein fraction was isolated from the culture filtrate of M.

Left ventricular diastolic dysfunction -- early cardiac impairment in patients with polymyositis/dermatomyositis: a tissue Doppler imaging study.

Objective: To investigate early cardiac involvement in patients with polymyositis/dermatomyositis (PM/DM), and to evaluate the risk factors for early cardiac impairment.

Methods: The study population included 46 patients with PM/DM who did not have overt cardiovascular manifestations and 21 age- and sex-matched healthy controls. Traditional echocardiography and tissue Doppler imaging (TDI) were used to evaluate cardiac function in both groups.
