The ver-1A gene was cloned and its nucleotide sequence was determined as part of a previous study on aflatoxin B1 (AFB1) biosynthesis in the filamentous fungus Aspergillus parasiticus SU-1. A second copy of this gene, ver-1B, was tentatively identified in this fungal strain. In this study, ver-1B was cloned by screening an A. parasiticus cosmid library with a ver-1A probe. The nucleotide sequen...

Vermiculite (Ver) enriched with silver and copper was used as nanofiller to the polyethylene (PE) matrix. Specifically, the low density polyethylene (LDPE) was chosen as a matrix. The samples Ver-Ag,Cu were prepared by shaking of Ver with the aqueous solutions of silver and copper nitrate. The mixtures of the Ver nanofillers and PE were homogenized by melt compounding technique and further thin...

In the mouse embryo, the body axis continues to develop after gastrulation as a tail forms at the posterior end of the embryo. Little is known about what controls outgrowth and patterning of the tail, but it has been speculated that the ventral ectodermal ridge (VER), a morphologically distinct ectoderm on the ventral surface near the tip of the tail, is a source of signals that regulate tail d...

Previous studies have shown that ver-1A encodes an enzyme which is directly involved in the conversion of versicolorin A to demethylsterigmatocystin during aflatoxin B1 (AFB1) biosynthesis in the filamentous fungus Aspergillus parasiticus. In this study, two different tools were utilized to study the regulation of ver-1A expression at the level of transcription and protein accumulation. First, ...

The visually evoked response (VER) to dim lights with intensities within the scotopic or lower mesopic range increased in amplitude during the progressive dark adaptation. The VER amplitude vs. time curve resembled the psychophysical dark adaptation curve. The spectral sensitivity curve of the dark-adapted VER matched the C.I.E. scotopic sensitivity curve. The dark-adapted VER was abnormal in p...

C-Sim is a programming tool for simulation of discrete processes using a method of pseudoparallel processes. It is an extension of C language obtained by including SIMULA-like macros and functions. C-Sim uses a special C-functions and C-macros library. The typical application area of C-Sim is functional validation of distributed, parallel and fault-tolerant systems and programs.

We introduce WISEMAN (Wireless Sensors Employing Mobile AgeNts), a mobile-code system for the programmable control of distributed tasks in wireless sensor networks. WISEMAN’s architecture and language constructs decouple the coordination element of distributed processes from the actual data processing in order to produce ultra-compact agents that may help to reduce bandwidth utilization. WISEMA...

PURPOSE Liposomes co-encapsulating doxorubicin (DOX) and verapamil (VER), and conjugated to transferrin (Tf-L-DOX/VER) were synthesized and evaluated in K562 leukemia cells. The design of this formulation was aimed at selective targeting of tumor cells, reducing cardiotoxicity of DOX and VER, as well as overcoming P-glycoprotein (Pgp)-mediated multidrug resistance (MDR) phenotype. METHODS The...

BACKGROUND Verapamil (Ver) is a well known, worldwide used drug to correct cardiac arrhythmias. The main Ver target is the L-type calcium channel. Modulation of calcium homeostasis vaulted Ver into use in medical applications. METHODS To examine COLO 205 cells morphology after Ver treatment, an electron microscopy technique was used. RESULTS This study shows ultrastructural evidence that Ve...

What is Scribalab 2.0? A system to create web communities and a modular toolbox for writing and publish on the web. It is made up of two main sections both designed to welcome users and visitors. You can find challenging and interesting tools into the Scriba section, such as ScribaMapping or Scriba6HATS with suggestions for cooperative group activities on creative writing or having the opportun...
