Influence of amylose on the pasting and gel texture properties of chestnut starch during thermal processing.

The quality of starchy foods is highly correlated with their amylose content. After boiling or roasting, the amylose content in cooked chestnut starch decreased to 16.6-26.

[Fingerprint of X-ray diffraction of Tibetan medicine dairy Nanhanshuishi and its application in processing by microwave].

The characteristic fingerprint of conventional dairy Nanhanshuishi was established by X-ray diffraction (XRD), based on similarity of caculation on public peaks by MATLAB software, and the feasibility of new dairy technology of microwave method was explored between XRD and the dissolution rate in artificial simulation gastric juices. The result showed that similarity of shared peak in XRD of conventional dairy Nanhanshuishi was > 95%, This XRD characteristic fingerprint of conventional dairy Nanhanshuishi had strong specificity, could be used to provide a reference for identification and quality evaluation. This study also showed that the similarity of microware dairy products and conventional dairy products was good, and the sample of microwave 15 min was the best, and new dairy method by the microwave could replace the traditional method.

Signal-to-noise performance analysis of streak tube imaging lidar systems. II. Theoretical analysis and discussion.

In the preceding paper (referred to here as paper I), we presented a general signal-to-noise performance analysis of a streak tube imaging lidar (STIL) system within the framework of linear cascaded systems theory. A cascaded model is proposed for characterizing the signal-to-noise performance of a STIL system with an internal or external intensified streak tube receiver. The STIL system can be decomposed into a series of cascaded imaging chains whose signal and noise transfer properties are described by the general (or the spatial-frequency dependent) noise factors (NFs).

Signal-to-noise performance analysis of streak tube imaging lidar systems. I. Cascaded model.

Streak tube imaging lidar (STIL) is an active imaging system using a pulsed laser transmitter and a streak tube receiver to produce 3D range and intensity imagery. The STIL has recently attracted a great deal of interest and attention due to its advantages of wide azimuth field-of-view, high range and angle resolution, and high frame rate. This work investigates the signal-to-noise performance of STIL systems.

[The angiographic features of exercise-induced ST-segment elevation in patients without myocardial infarction].

Objective: To explore the incidence and angiographic features of exercise-induced ST-segment elevation in patients without prior myocardial infarction.

Methods: Exercise-induced ST-segment elevation occurred in 15 out of 4601 consecutive patients without prior myocardial infarction underwent treadmill exercise testing during a 2-year period. The coronary angiographic features of the 15 patients (13 males, aged between 40 - 75 years) were analyzed.

Enhanced myocardial cathepsin B expression in patients with dilated cardiomyopathy.

Objective: Cathepsin B is a prominent lysosomal protease and is involved in apoptosis as well as degradation of myofibrillar proteins in myocardial infarction. The aim of this study was to investigate myocardial cathepsin B expression in failing and non-failing human hearts.

Methods: Tissue samples were taken from transplanted left ventricles from 20 patients with dilated cardiomyopathy and 5 non-failing donor hearts that could not be transplanted for technical reasons.
