Galectin-7 is a beta-galactoside binding protein specifically expressed in stratified epithelia and notably in epidermis, but barely detectable in epidermal tumors and absent from squamous carcinoma cell lines. Galectin-7 gene is an early transcriptional target of the tumor suppressor protein P53 [Polyak, K., Xia, Y., Zweier, J., Kinzler, K. & Vogelstein, B. (1997) Nature (London) 389, 300-305]...

The well-known spherical-deformed-transitional nucleus and potential $0\ensuremath{\nu}\ensuremath{\beta}\ensuremath{\beta}\phantom{\rule{4pt}{0ex}}$emitter $^{150}\mathrm{Nd}\phantom{\rule{4pt}{0ex}}$and its daughter $^{150}\mathrm{Sm}\phantom{\rule{4pt}{0ex}}$were investigated in nuclear resonance fluorescence experiments using quasimonoenergetic, linearly polarized $\ensuremath{\gamma}$-ray ...

A nanoelectrospray ionization mass spectrometry (ESI-MS) source and interface has been designed that enables efficient ion production and transmission in a 30 Torr pressure environment using solvents compatible with typical reversed-phase liquid chromatography (RPLC) separations. In this design, the electrospray emitter is located inside the mass spectrometer in the same region as an electrodyn...

ETRI Journal, Volume 28, Number 3, June 2006 ABSTRACT—Monolithic SiGe heterojunction bipolar transistor (HBT) variable gain amplifiers (VGAs) with a feedforward configuration have been newly developed for 5 GHz applications. Two types of the feedforward VGAs have been made: one using a coupled-emitter resistor and the other using an HBT-based current source. At 5.2 GHz, both of the VGAs achieve...

Introduction: Accelerated Partial Breast Irradiation (APBI) is an effective treatment for breast carcinomas because of its limited number of fractions. Strut-adjusted volume implant (SAVI) is a HDR brachytherapy applicator to deliver the prescription dose with good PTV coverage and acceptable dose to skin, chest wall and organ at risks. Acceptable clinical outcomes depend on a...

Introduction: Skin cancer has been increased day by day, but it can be cured if it diagnosed early. After reviewing the scientific literature about 980 nm diode laser, and its multiple advantages on skin diseases. We studied in this paper the effectiveness of this type of laser on the progression of skin cancer among hamsters which were exposed to carcinogen on the bac...

introduction: with the rapid increase in use of lasers in medical treatments, it is important to understand the mechanisms of heat transfer in biological tissues in order to minimize damage to the tissues resulting from extra heat applied. the aim of this study is to investigate the temperature distribution in living biological tissues when laser irradiation is used in a treatment. methods:  in...

Previously we defined a pathway of transforming growth factor beta (TGF-beta) and stromal cell-derived factor-1/CXC chemokine ligand 12 (SDF-1alpha/CXCL12) dependent migration of adult haematopoietic stem and progenitor cells (HPC) towards glioma cells in vitro and their homing to experimental gliomas in vivo. Hypoxia is a critical aspect of the microenvironment of gliomas and irradiation is an...

52 VITAMIN D—BIOMOLECULAR CHARACTERISTICS There are two ways of acquiring vitamin D—cutaneous irradiation and diet. In the skin, cholecalciferol is synthesized through UV irradiation of 7-dihydrocholesterol. In infants, immobile or institutionalized persons, the elderly (>70 years old), and veiled women or those living in northern latitudes, sun radiation may not be a sufficient source of vitam...
