Human Papillomavirus (HPV) Detection in Cytologic Specimens: Similarities and Differences of Available Methodology.

Accumulating evidence regarding the causative role of human papillomavirus (HPV) in a wide range of malignant and nonmalignant diseases highlights the importance of HPV testing. This study describes and discusses the efficacy and characteristics of 4 well-established and commercially available tests. Here, 181 cytologic specimens from cervical smears were analyzed using the HPV SIGN PQ (Diatech) and the Linear Array (Roche) method.

The relationship between duration of initial alcohol exposure and persistence of molecular tolerance is markedly nonlinear.

The neuronal calcium- and voltage-activated BK potassium channel is modulated by ethanol, and plays a role in behavioral tolerance in vertebrates and invertebrates. We examine the influence of temporal parameters of alcohol exposure on the characteristics of BK molecular tolerance in the ventral striatum, an important component of brain reward circuitry. BK channels in striatal neurons of C57BL/6J mice exhibited molecular tolerance whose duration was a function of exposure time.

Posttranscriptional regulation of BK channel splice variant stability by miR-9 underlies neuroadaptation to alcohol.

Tolerance represents a critical component of addiction. The large-conductance calcium- and voltage-activated potassium channel (BK) is a well-established alcohol target, and an important element in behavioral and molecular alcohol tolerance. We tested whether microRNA, a newly discovered class of gene expression regulators, plays a role in the development of tolerance.
