BACKGROUND AND OBJECTIVE The Intubating Laryngeal Mask Airway FastrachTM (ILMA) has been used with success in difficult intubation cases. The purpose of this study is to evaluate the effect of mouth opening, Mallampati classification, thyromental distance and Cormack-Lehane Grade, on the ease of ILMA use. METHODS Eighty one patients ASA I-II, were assessed preoperatively for mouth opening, Ma...

AIM The traditional architecture based classification system of ductal carcinoma in situ (DCIS) has been criticised on the grounds that individual lesions often show more than one pattern resulting in a large mixed category. New DCIS classification systems have emphasised the importance of cytological grade, which is reputed to be more uniformly expressed throughout a lesion. This study investi...

Short wave infrared hyperspectral imaging was tested for its ability to distinguish rooibos tea ( Aspalathus linearis) based on production area and quality grade, with the aim replace time-consuming sensory analysis in industry. The number of latent variables model parameters calibration were optimised by cross-validation. Classification error rates used evaluate performance models classifying ...

BACKGROUND The WHO classification of brain tumours describes 15 subtypes of meningioma. Nine of these subtypes are allotted to WHO grade I, and three each to grade II and grade III. Grading is based solely on histology, with an absence of molecular markers. Although the existing classification and grading approach is of prognostic value, it harbours shortcomings such as ill-defined parameters f...

Second-year undergraduated students from 2008, 2009, and 2010 cohorts were asked to respond a questionnaire to determine their learning style preferences, the VARK questionnaire (where V is visual, A is aural, R is reading-writing, and K is kinesthetic), which was translated into Spanish by the author. The translated questionnaire was tested for wording comprehension before its application in t...

in the open-pit mining, one of the first decisions that must be made in production planning stage, after completing the design of final pit limits, is determining of the processing plant cut-off grade. since this grade has an essential effect on operations, choosing the optimum cut-off grade is of considerable importance. different goals may be used for determining optimum cut-off grade. one of...

BACKGROUND AND PURPOSE The pattern of contrast leakage from DSC tissue signal intensity time curves have shown utility in distinguishing adult brain neoplasms, but has limited description in the literature for pediatric brain tumors. The purpose of this study is to evaluate the utility of grading pediatric brain tumors with this technique. MATERIALS AND METHODS A retrospective review of tissu...
