Atomic Force Microscopy Imaging of Crystalline Sucrose in Alcohols.

Imaging nanometer- or molecule-scale topography has been achieved by dynamic atomic force microscopy (AFM) when a solid object of interest is damaged by vacuum exposure or electron irradiation. Imaging in a liquid offers a means to remove contaminations from the surface scanned using the microscope tip when the object is soluble to the surrounding liquid, typically water. In the present study, we attempted to take topographic images of crystalline sucrose.

Atomic-scale topography of rutile TiO(110) in aqueous solutions: A study involving frequency-modulation atomic force microscopy.

Nanometer-Scale Distribution of a Lubricant Modifier on Iron Films: A Frequency-Modulation Atomic Force Microscopy Study Combined with a Friction Test.

Liquid lubricants used in mechanical applications are low-vapor-pressure hydrocarbons modified with a small quantity of polar compounds. The polar modifiers adsorbed on the surface of sliding solids dominate the friction properties when the sliding surfaces are in close proximity. However, a few methods are available for the characterization of the adsorbed modifiers of a nanometer-scale thickness.

A case of primary breast angiosarcoma with multiple discontinuous small lesions.

Background: Angiosarcoma of the breast is rare. It carries a poor prognosis because of its high risk of local recurrence and distant metastases. Presently, there are still no established systemic therapies.

[A Case of Segmental Arterial Mediolysis:Subarachnoid Hemorrhage Followed by Abdominal Bleeding].

We describe a case involving subarachnoid and intraperitoneal hemorrhage due to segmental arterial mediolysis(SAM). A 77-year-old female patient with sudden subarachnoid hemorrhage was immediately transferred to our institution. The hemorrhage was classified as grade 2 according to the World Federation of Neurosurgical Societies system.

Semaphorin signaling via MICAL3 induces symmetric cell division to expand breast cancer stem-like cells.

Cancer stem-like cells (CSCs) are expanded in the CSC niche by increased frequency of symmetric cell divisions at the expense of asymmetric cell divisions. The symmetric division of CSCs is important for the malignant properties of cancer; however, underlying molecular mechanisms remain largely elusive. Here, we show a cytokine, semaphorin 3 (Sema3), produced from the CSC niche, induces symmetric divisions of CSCs to expand the CSC population.

[Omental Flap for the Device Infection of the HeartMate II].

Case 1:An 18-year-old male underwent emergent left extracorporeal ventricular assist device(eVAD) implantation for a cardiogenic shock because of dilated cardiomyopathy (DCM). After listing for heart transplant, he underwent a HeartMate II implantation as bridge-to-bridge(BTB) therapy. The omental flap was simultaneously used to prevent device infection that could have been induced by the infected malgranulation around the cannulas of the eVAD.

Correction to: Cerebral oximetry for cardiac surgery: a preoperative comparison of device characteristics and pitfalls in interpretation.

In the original publication, the length unit of the SCD in Table 1 and Fig. 2 has been incorrectly published as cm. The correct length unit is mm.

Cerebral oximetry for cardiac surgery: a preoperative comparison of device characteristics and pitfalls in interpretation.

Regional cerebral oximetry using near-infrared spectroscopy devices is commonly used for detecting cerebral ischemia during cardiopulmonary bypass, and aim to avoid poor cerebral perfusion which may result in perioperative neurological impairment. Today, several devices that can detect cerebral ischemia are commercially available. Although these devices operate on the same measurement principles, their algorithms for detecting and calculating cerebral ischemia are different and no criteria for directly comparing values measured by such different devices exist.
