Segmental partial thrombosis of the corpora cavernosa: Case report and diagnostic/therapeutic algorithm.

Cavernous body thrombosis is a rare condition. The etiology and pathophysiology of this entity is still poorly understood and there is no clear diagnostic and treatment algorithm. The objective of this article is to publish a clinical case of a partial segmental thrombosis of the corpus cavernosum and present a flow chart for diagnosis and treatment based on the review of the published literature on this disease.

Filament identification in wide-angle high speed imaging of the mega amp spherical tokamak.

A new tomographic inversion technique is presented for the identification of plasma filaments in wide-angle visible camera data. The technique works on the assumption that background subtracted images of filaments can be represented as a superposition of uniformly emitting magnetic equilibrium field lines. A large collection of equilibrium magnetic field lines is traced and projected onto the camera field of view and combined to form a geometry matrix describing the coordinate transformation from magnetic field aligned coordinates to image pixel coordinates.

Nonlinear saturation of tearing mode islands.

New, rigorous results for the tearing island saturation problem are presented. These results are valid for the realistic case where the magnetic island structure is non-symmetric about the reconnection surface and the electron temperature, on which the electrical resistivity depends, is evolved self-consistently with the island growth.

Nicotine gum dose and weight gain after smoking cessation.

The authors examined weight gain in 79 abstinent cigarette smokers during treatment with placebo or with 2 mg or 4 mg of nicotine gum. Results indicated that nicotine gum suppressed weight gain in a linear fashion with increasing nicotine dose. At 90 days postcessation, placebo gum users gained 3.

Depression and smoking cessation: characteristics of depressed smokers and effects of nicotine replacement.

Previous research has linked depression to difficulties in smoking cessation. The authors followed 269 smokers who attempted to quit smoking for 3 months. Participants were given nicotine gum (2 or 4 mg) or placebo gum and brief counseling.
