Differentiation of muscle cells is characterized morphologically by the acquisition of contractile filaments and characteristic shape changes, and on the molecular level by induction of the expression of several genes, including those for the muscle-specific alpha-actin isoforms. IFN-gamma is an inhibitor of proliferation for several cells, including vascular smooth muscle, and is also an induc...

The dark photon not only provides a portal linking sector particles and ordinary matter but also is well-motivated candidate. We propose to detect the through inverse Compton-like scattering process $p+{\ensuremath{\gamma}}^{\ensuremath{'}}\ensuremath{\rightarrow}p+\ensuremath{\gamma}$. Thanks ultrahigh energy primary cosmic rays, we find that such method able probe mass from ${10}^{\ensuremath...

Cellular repair of DNA damage due to lethal gamma irradiation was studied to reveal differences between strains and cell cycle stages that are otherwise difficult to detect. Cycling and metaphase-blocked cultures of normal fibroblasts and carcinoma cells were compared for repair of gamma sites (gamma radiation-induced nicks, breaks, and alkalilabile sites in DNA) at supralethal exposures rangin...

Behavioral studies of visual recognition memory indicate that old/new decisions reflect both the similarity of the probe to the studied items (probe-item similarity) and the similarities among the studied items themselves (list homogeneity). Recording intracranial electroencephalography from 1,155 electrodes across 15 patients, we examined the oscillatory correlates of probe-item similarity and...

Gamma-rays can be produced by the interaction of a relativistic jet and the matter of the stellar wind in the subclass of massive X-ray binaries known as “microquasars”. The relativistic jet is ejected from the surroundings of the compact object and interacts with cold protons from the stellar wind, producing pions that then quickly decay into gamma-rays. Since the resulting gamma-ray emissivit...

The temperature dependence of the upper (H(c2)) and lower (H(c1)) critical fields has been deduced from Hall probe magnetization measurements of high quality MgB2 single crystals along the two main crystallographic directions. We show that Gamma(H(c2))=H(c2 axially ab)/H(c2 axially c) and Gamma(H(c1))=H(c1 axially c)/H(c1 axially ab) differ significantly at low temperature (being approximately ...

BACKGROUND Intraoperative localization of image or endoscopy-detected lesions occasionally pose surgical challenges due to the small lesion size and/or difficult anatomic exposure. Identification of such lesions can be facilitated using a hand-held gamma probe with utilization of Tc-99m macroaggregate albumen (MAA) localization technique. The radiopharmaceutical injection can be performed using...

A. This guideline is written specifically for lymphoscintigraphy in patients with primary melanomas that originate in the skin. Staging of these tumors is based on tumor thickness (Breslow measurement) and level of skin invasion (Clark’s level), both of which are determined by the pathologist from a biopsy sample. Ample data correlate patient survival with Breslow and Clark measurements. In the...

Class I human alcohol dehydrogenase (ADH; alcohol:NAD+ oxidoreductase, EC 1.1.1.1) consists of several homo- and heterodimers of alpha, beta, and gamma subunits that are governed by the ADH1, ADH2, and ADH3 loci. We previously cloned a full length of cDNA for the beta subunit, and the complete sequence of 374 amino acid residues was established. cDNAs for the alpha and gamma subunits were clone...
