High grade soft tissue sarcomas often show histological invasion to adjacent compartment including bone and vessel. This study aimed to evaluate histological invasion in high grade soft tissue sarcomas, clarify its impact on prognosis and devise treatment strategies. We retrospectively reviewed 133 patients with non-small round cell high grade soft tissue sarcomas surgically treated between 200...

OBJECTIVE To investigate the contributions of adenoid and tonsil size to childhood obstructive sleep apnea (OSA) and the interactions between adenotonsillar hypertrophy, age, and obesity in children with OSA. METHODS In total, 495 symptomatic patients were recruited. The patients were assigned to four groups according to age: toddler (age 1-3, n=42), preschool (age 3-6, n=164), school (age 6-...

BACKGROUND With the backdrop of a global ecstasy epidemic, this study sought to examine the trend, correlates, and onset sequence of ecstasy use among adolescents in Taiwan, where a well-established gateway drug such as marijuana is much less popular. METHODS A multistage probability survey of school-attending adolescents in grades 7, 9, 10, and 12, aged 11-19 years, was conducted in 2004, 20...

The response of Baban Tsauni (Nigeria) lead-gold ore to gravity separation methods was investigated in this research work. Value addition to run-off mines is always necessary in order to reduce downstream metal extraction costs. Gravity separation methods (the focus of this work) are the cheapest beneficiation methods. This study applied three gravity separation methods: jigging, multi-gravity ...

in the course of this study, empirical models were developed for the pressure-density relationship in a large cubic baler for baling alfalfa and barley straw. least squares regression analysis was employed to develop the empirical model and estimate the model coefficients by minimizing the summation of the squared differences between data resulting from the developed empirical model and the cor...

BACKGROUND It is helpful in planning treatment for patients with ductal carcinoma in situ (DCIS) if the size and grade could be reliably predicted from the mammography. The aims of this study were to determine if the type of calcification can be best used to predict histopathological grade from the mammograms, to examine the association of mammographic appearance of DCIS with grade and to asses...
