We have treated two patients with extramammary Paget's disease/carcinoma (EMPD/C), a 62-year-old woman and a 78-year-old man. In both patients, lymph nodes in the areas of the bilateral inguinal, external iliac arteries, and abdominal aorta were affected. After surgery, they underwent 5 courses of systemic combination chemotherapy at 4-week intervals to(More)
BACKGROUND Most estrogen dermatitides are induced by local or systemic contact dermatitis where dendritic cells are central, and tamoxifen has a blocking effect on dendritic cells. METHODS We present 5 cases of estrogen dermatitis in which the clinical features were prurigo, urticaria, acneiform eruption and annular erythema. RESULTS Tamoxifen was(More)
Construction of an active composite with multicolor visible and broadband near-infrared luminescence is of great technological importance for various applications, including three-dimensional (3D) display, broadband telecommunication, and tunable lasers. The major challenge is the effective management of energy transfer between different dopants in(More)
Intermetallic Nd(2)Fe(14)B nanoparticles with an average diameter of 30 nm, which are smaller than a theoretical single magnetic domain size of 220 nm, were successfully prepared by the femtosecond laser fragmentation in liquid. The self-passivating amorphous carbon layer resulting from the decomposition of the surrounding solvent prevents the Nd(2)Fe(14)B(More)
In its standard version, our BioPhotonics Workstation (BWS) can generate multiple controllable counter-propagating beams to create real-time user-programmable optical traps for stable three-dimensional control and manipulation of a plurality of particles. The combination of the platform with microstructures fabricated by two-photon polymerization (2PP) can(More)
Good solvent effects of C(70) cluster formations and their electron-transporting and photoelectrochemical properties have been systematically examined for the first time. Nano-to-micrometer scale assemblies of C(70) with different morphologies were prepared by rapidly injecting poor solvent (i.e., acetonitrile) into a solution of C(70) dissolved in various(More)
The structural changes inside rock-salt crystals after femtosecond (fs) laser irradiation are investigated using a microscopic pump-probe technique and an elastic simulation. The pump-probe imaging shows that a squircle-shaped stress wave is generated after the fs laser irradiation as a result of the relaxation of thermal stress in the photoexcited region.(More)
