BACKGROUND Gene expression profiling yields quantitative data on gene expression used to create prognostic models that accurately predict patient outcome in diffuse large B cell lymphoma (DLBCL). Often, data are analyzed with genes classified by whether they fall above or below the median expression level. We sought to determine whether examining multiple cut-points might be a more powerful tec...

in this research anxiety and depression and their association with 32 different factors in students of hamedan university of medical sciences were measured. levels of anxiety and depression were assessed by state-trait anxiety inventory (from 2, trait) and beck depression inventory. a questionnaire made of demographic data, educational and noneducational activities, the presence of medical or p...

Actigraph accelerometers are hypothesized to be valid measurements for assessing children's sedentary time. However, there is considerable variation in accelerometer cut-points used. Therefore, we compared the most common accelerometer sedentary cut-points of children performing sedentary behaviors. Actigraph Actitrainer uniaxial accelerometers were used to measure children's activity intensity...

subject to A X = b and that,X is an extreme point of DX=d, X>O, is developed. The procedure will avoid the investigation of many of the extreme points of DX = d, X > 0 and also alternative optimas of different best extreme points of DX = d, X >_ 0 will not be needed. The algorithm is expected to work very efficiently. Zusammenfassung: In dieser Arbeit "Strong-Cut Enumerative Procedure for Extre...

In ELISAs, sera of individuals infected by Trypanosoma cruzi show absorbance values above a cut-off value. The cut-off is generally computed by means of formulas that need absorbance readings of negative (and sometimes positive) controls, which are included in the titer plates amongst the unknown samples. When no controls are available, other techniques should be employed such as change-point a...

12 We analyze spectral graph theory based image segmentation algorithms and 13 show there is a natural connection with edge preserving filtering. Based on 14 this connection we show that the normalized cut algorithm is equivalent to 15 repeated application of bilateral filtering. Then, using this interpretation we 16 present and implement a fast normalized cut algorithm. Experiments show 17 tha...

BACKGROUND The prevalence of depressive symptoms in hypothyroidism is high. Considering that hypothyroidism and depression share some clinical features, some researchers use the "brain hypothyroidism" hypothesis to explain the pathogenesis of depression. We aimed to detect a new TSH cut-off value in hypothyroidism based on depression symptoms. METHODS A cross-sectional study was conducted on ...

Act 92 of 1996, the Choice on Termination of Pregnancy Act, seeks to promote female autonomy. The Act makes no reference to the nature of the abortus--implying its moral insignificance. Utilitarian arguments on the value of life strongly support this position. Utilitarians argue that neither belonging to the human species, nor possession of the potential to develop into a person, is a significa...

Abortion is one of the controversial issues discussed in medical ethics. We can formulate the argument which is put forward by the opponents of abortion as follows: 1) fetus has to be regarded as human being; 2) killing an innocent human being is morally wrong; 3) aborting is an example of killing and terminating a human being's life. So, being engaged in aborting is morally wrong. In this pape...
