Cardiomyocyte-specific inactivation of thyroid hormone in pathologic ventricular hypertrophy: an adaptative response or part of the problem?
Recent studies in various rodent models of pathologic ventricular hypertrophy report the re-expression of deiodinase type 3 (D3) in cardiomyocytes. D3 inactivates thyroid hormone (T3) and is mainly expressed in tissues during development. The stimulation of D3 activity in ventricular hypertrophy and subsequent heart failure is associated with severe impairment of cardiac T3 signaling. Hypoxia-induced signaling appears to drive D3 expression in the hypertrophic cardiomyocyte, but other signaling cascades implicated in hypertrophy are also capable of stimulating transcription of the DIO3 gene. Many cardiac genes are transcriptionally regulated by T3 and impairment of T3 signaling will not only reduce energy turnover, but also lead to changes in gene expression that contribute to contractile dysfunction in pathologic remodeling. Whether stimulation of D3 activity and the ensuing local T3-deficiency is an adaptive response of the stressed heart or part of the pathologic signaling network leading to heart failure, remains to be established

Laser coupling to reduced-scale targets at NIF Early Light
Deposition of maximum laser energy into a small, high-Z enclosure in a short laser pulse creates a hot environment. Such targets were recently included in an experimental campaign using the first four of the 192 beams of the National Ignition Facility [J. A. Paisner, E. M. Campbell, and W. J. Hogan, Fusion Technology 26, 755 (1994)], under construction at the University of California Lawrence Livermore National Laboratory. These targets demonstrate good laser coupling, reaching a radiation temperature of 340 eV. In addition, the Raman backscatter spectrum contains features consistent with Brillouin backscatter of Raman forward scatter [A. B. Langdon and D. E. Hinkel, Physical Review Letters 89, 015003 (2002)]. Also, NIF Early Light diagnostics indicate that 20% of the direct backscatter from these reduced-scale targets is in the polarization orthogonal to that of the incident light
A Job Safety Program for Construction Workers Designed to Reduce the Potential for Occupational Injury Using Tool Box Training Sessions and Computer-Assisted Biofeedback Stress Management Techniques
This project was conducted with a multicultural construction company in Hawaii, USA. The job duties performed included drywall and carpentry work. The following objectives were selected for this project: (a) fire prevention training and inspection of first aid equipment; (b) blood-borne pathogen training and risk evaluation; (c) ergonomic and risk evaluation intervention program; (d) electrical safety training and inspection program; (e) slips, trips, and falls safety training; (f) stress assessment and Personal Profile System; (g) safety and health program survey; (h) improving employee relations and morale by emphasizing spirituality; and (i) computer-assisted biofeedback stress management training. Results of the project indicated that observed safety hazards, reported injuries, and levels of perceived stress were reduced for the majority of the population
