The typical sonographic appearance of liver hemangiomas is a well-demarcated hyperechoic mass with homogeneous echodensity. Focal liver lesions may change their ultrasound characteristics over time. We present a case of dynamic pattern of liver hemangiomas during a state of systemic inflammation.

Background: The aim of this study was to evaluate the inhibitory growth effects of different potential chemopreventive agents in vitro and to determine their influence on PSA mRNA and protein expression with an established screening platform.

Methods: LNCaP and C4-2 cells were incubated with genistein, seleno-L-methionine, lycopene, DL-alpha-tocopherol, and trans-beta-carotene at three different concentrations and cell growth was determined by the MTT assay. PSA mRNA expression was assessed by quantitative real-time RT-PCR and secreted PSA protein levels were quantified by the microparticle enzyme immunoassay.

Purpose: The antiproliferative effects of pharmacological agents used for androgen ablative therapy in prostate cancer, including goserelin, bicalutamide and cyproterone acetate (Fluka Chemie, Buchs, Switzerland), were tested in vitro. It was determined whether they affected prostate specific antigen mRNA and protein expression independent of growth inhibition.

Materials And Methods: Goserelin, bicalutamide (AstraZeneca, Zug, Switzerland) and cyproterone acetate were added to prostate specific antigen expressing, androgen dependent LNCaP and androgen independent C4-2 cell line (Urocor, Oklahoma City, Oklahoma) cultures.

Background: Pouch development is a potentially serious problem following gastric banding, and reoperation is often demanded to maintain long-term function of the lap band. Laparoscopic gastric banding was performed with two different calibrations of the pouch. Within a period of 12 months, postoperative pouch behavior with regard to volume and shape was evaluated retrospectively, as were changes in the distal esophagus.
