This paper reports two cases of acrometastasis to the hands. The first case involved a 78-year-old woman with a permeative osteolytic lesion in her proximal second metacarpal. A biopsy of this lesion suggested a diagnosis of non-small-cell lung carcinoma with secondary osseous metastasis. This was the first presentation of the woman's primary diagnosis. A… (More)
BACKGROUND Many computational chemistry analyses require the generation of conformers, either on-the-fly, or in advance. We present Confab, an open source command-line application for the systematic generation of low-energy conformers according to a diversity criterion. RESULTS Confab generates conformations using the 'torsion driving approach' which… (More)
The main objective of this study was to determine whether the excitotoxic cholinesterase inhibitor soman increases the catabolism of phospholipids in rat brain. Injections of soman (70 micrograms/kg, s.c.), at a dose that produced toxic effects, increased the levels of both free fatty acids (175-250% of control) and free choline (250% of control) in rat… (More)
The role of cholinergic and non-cholinergic mechanisms in mediating organophosphate cholinesterase (ChE) inhibitor-induced elevations in choline levels in brain was investigated. The nerve agents soman and sarin, when administered to rats at doses greater than the IC50 for acetylChE inhibition, significantly increased the levels of choline and acetylcholine… (More)
RATIONALE Prior studies had suggested (a) that a lessened ability to clear ingested forms of the large neutral amino acid (LNAA), phenylalanine (Phe), was associated with having tardive dyskinesia (TD), and (b) that greater availability of a group of LNAA, the branched chain amino acids (BCAA), concomitant with the lower availability of Phe to the brain are… (More)
In this report, we describe the fractionation of crude axolemmal fractions from rat lower brainstem into subfractions enriched in markers for either periaxolemmal myelin or axolemma. These subfractions were isolated on density gradients as bands layering on 0.8M and 1.0M sucrose. Both subfractions consisted of unilamellar vesicles. Relative to myelin… (More)
The Atmospheric Radiation Measurement (ARM) Aerosol Observing System (AOS) has been operating at the Southern Great Plains (SGP) Central Facility since 1996. In response to the cross-cutting broad-band heating rate profile value added product (VAP), there has been an increasing desire within the ARM community not only for those aerosol products directly… (More)
