Image compression techniques based on wavelet and fractal coding have been recognized signiicantly useful in image texture classiication and discrimination. In fractal coding approach, each image is represented by a set of self-transformations through which an approximation of the original image can be reconstructed. These transformations of images can be(More)
Large visual database systems require eeective and eecient ways of indexing and accessing visual data on the basis of content. In this process, signiicant features must rst be extracted from image data in their pixel format. These features must then be classiied and indexed to assist eecient access to image content. With the large volume of visual data(More)
BACKGROUND The single-row and double-row fixation techniques have been widely used for rotator cuff tears. However, whether the double-row technique produces superior clinical or anatomic outcomes is still considered controversial. This study aims to use meta-analysis to compare the clinical and anatomical outcomes between the two techniques. METHODS The(More)
BACKGROUND Platelet-rich products (PRP) are widely used for rotator cuff tears. However, whether platelet-rich products produce superior clinical or radiological outcomes is controversial. This study aims to use meta-analysis to compare clinical and radiological outcomes between groups with or without platelet-rich products. METHODS The Pubmed, Embase,(More)
BACKGROUND Both tenotomy and tenodesis have been widely used for the treatment of long head of biceps tendon (LHBT) lesions, but the optimal strategy remains considerably controversial. In this meta-analysis of published studies, we compared the results of the two procedures. METHODS A literature search that compared tenotomy with tenodesis was performed(More)
Nowadays it remains a controversial issue whether a correlation exists between the apoptosis rate of tumor tissue and the prognosis of the patients. We aimed to explore the prognostic significance of apoptosis index of human osteosarcoma tissue. The technique of terminal DNA breakpoints in situ 3 - hydroxy end labeling (TUNEL) was used to detect and(More)
Anopheles lesteri and Anopheles sinensis are two major malaria vectors in China and Southeast Asia. They are dramatically different in terms of geographical distribution, host preference, resting habitats, and other traits associated with ecological adaptation and malaria transmission. Both species belong to the Anopheles hyrcanus group, but the extent of(More)
BACKGROUND Tear conversion followed by repair and trans-tendon techniques have been widely used for partial-thickness rotator cuff tears. Both of them showed favorable results with regard to the management of articular-sided partial-thickness rotator cuff tears (PTRCTs) of more than 50% thickness. However, controversy continues with the best management.(More)
