Bacterial virulence: can we draw the line?

The molecular approach to microbial pathogenesis has resulted in an impressive amount of data on bacterial virulence genes. Bacterial genome sequences rapidly add candidate virulence genes to electronic databases. The interpretation of this overwhelming information is obscured because every gene involved in pathogenicity is called a virulence gene, regardless of its function in the complex proc...

How to draw the line in biomedical research

The use of the least squares method to calculate the best-fitting line through a two-dimensional scatter plot typically requires the user to assume that one of the variables depends on the other. However, in many cases the relationship between the two variables is more complex, and it is not valid to say that one variable is independent and the other is dependent. When analysing such data resea...

Treating prostate cancer: where do we draw the line?

The article by Drs. Lepor and Donin is a provocative look at a timely topic in urologic oncology.[1] There is little debate among experts in the field that we are overtreating prostate cancer at the current time. Studies are ongoing to evaluate active surveillance as an option for low-risk tumors, even in men with very long life expectancies. However, in this review, the authors have overreache...

Draw a line on your PDA to authenticate

The trend toward a highly mobile workforce and the ubiquity of graphical interfaces (such as the stylus and touch-screen) has enabled the emergence of graphical authentications in Personal Digital Assistants (PDAs) [1]. However, most of the current graphical password schemes are vulnerable to shoulder-surfing [2,3], a known risk where an attacker can capture a password by direct observation or ...
