Respiratory Protection Principles and Applications

Small interfering RNA; principles, applications and challenges--

Gene silencing using RNAi (RNA interference), has recently been used as a successful laboratory technique in determining the function and control of gene expression and provides a wide range of applications in molecular biology and gene therapy. RNAi is a method of suppressing gene expression. In this direction, a single-stranded RNA molecule of about 21–23 nucleotides, called siRNA (small inte...

The Principles and Recent Applications of Bioelectrocatalysis

Bioelectrocatalysis is a phenomenon concerned with biological catalysts, which accelerate the electrochemical reactions. Bioelectrocatalysis has been widely explored by the research community in various directions. Enzymes can catalyze different chemical reactions in living organisms by enzymes as the most important biological catalysts. These enzymatic biocatalysts are commercially available a...

Respiratory protection.

Severe acute respiratory syndrome and respiratory protection.

To the Editor—Severe acute respiratory syndrome (SARS) emerged last year as a new infectious disease, as well as an occupational hazard for health care workers treating infected patients. The Centers for Disease Control and Prevention (CDC) recently drafted guidlines suggesting that routes of transmission of the SARS-associated coronavirus (CoV) involve the mucous membranes, such as the respira...

neuronavigation: principles, clinical applications and potential pitfalls.

localization of brain lesions and prevention of damage to vital structures are important in operation of brain pathologies. despite development of many techniques including angiography, mri, sonography, and frame base stereotaxy, a more accurate localizing technique is still needed (1, 2). a step forward to achieve this goal is to develop a navigation system. in this manuscript, we explained so...
