Minimally-invasive Right Hepatectomy for Perihilar Cholangiocarcinoma.

The magnification of images provided by minimally-invasive surgery (MIS) allows a very sharp and precise dissection of the hepatic hilum, allowing to overcome the technical complexity of surgery of perihilar cholangiocarcinoma (PHC). Recently, the feasibility and reproducibility of MIS for PHC are reported: within centers with adequate expertise and respecting the cornerstones of oncological adequacy, it provides short term advantages in a selected population of patients. The video reports the case of a patient with PHC involving the right biliary duct and requiring right hepatectomy with biliary confluence and segment 1 resection, with associated lymphadenectomy.

Influence of different boost techniques on radiation dose to the left anterior descending coronary artery.

Purpose: The purpose of this study is to compare the dosimetry of electron beam (EB) plans and three-dimensional helical tomotherapy (3DHT) plans for the patients with left-sided breast cancer, who underwent breast conserving surgery.

Materials And Methods: We selected total of 15 patients based on the location of tumor, as following subsite: subareolar, upper outer, upper inner, lower lateral, and lower medial quadrants. The clinical target volume (CTV) was defined as the area of architectural distortion surrounded by surgical clip plus 1 cm margin.

Characteristics of fracture during the approach process and wear mechanism of a silicon AFM tip.

The wear of an atomic force microscope (AFM) tip is one of the crucial issues in AFM as well as in other probe-based applications. In this work, wear tests under extremely low normal load using an AFM were conducted. Also, in order to understand the nature of silicon tip wear, the wear characteristics of crystal silicon and amorphous silicon oxide layer were investigated by a high-resolution transmission electron microscope (HRTEM).

Antiinflammatory effects of genipin, an active principle of gardenia.

Genipin, the aglycone of geniposide, is metabolically produced from the geniposide in body tissues. The purpose of this study is to clarify some pharmacological actions of genipin. Genipin showed concentration-dependent inhibition on lipid peroxidation induced by Fe++/ascorbate in rat brain homogenate.

Neuroprotective effects of antioxidative flavonoids, quercetin, (+)-dihydroquercetin and quercetin 3-methyl ether, isolated from Opuntia ficus-indica var. saboten.

The flavonoids quercetin, (+)-dihydroquercetin, and quercetin 3-methyl ether were isolated from the ethyl acetate fractions of the fruits and stems of Opuntia ficus-indica var. saboten. In the present study, we evaluated their protective effects against oxidative neuronal injuries induced in primary cultured rat cortical cells and their antioxidant activities by using three different cell-free bioassays.
