Chagasin may be considered a potential plant-incorporated protectant (PIP) protein due to its deleterious effects on insect pests. However, extensive safety studies with PIP's are necessary before introducing them into the target plant. Thus, a short-term feeding trial in rats with high doses of r-chagasin was conducted to provide evidences about its safety. Three test diets containing casein +...

Ultraviolet (UV)-associated cancer is the most common cancer in the United States. Approximately 90% of nonmelanoma skin cancer and 65% of melanoma are attributable to UV exposure and theoretically could be eliminated by primary prevention measures. Safe sun strategy includes use of sunscreens, use of protective clothing, minimization of exposure from 10 A.M. to 3 P.M., and avoidance of tanning...

Development of radio-protective agents that are non-toxic is critical in light of ever increasing threats associated with proliferation of nuclear materials, terrorism and occupational risks associated with medical and space exploration. In this communication, we describe the discovery, characterization and mechanism of action of ON01210.Na, which effectively protects mouse and human bone marro...

The effect of mechanical agitation on the microalgae Phaeodactylum tricornutum and Porphyridium cruentum was investigated in aerated continuous cultures with and without the added shear protectant Pluronic F68. Damage to cells was quantified through a decrease in the steady state concentration of the biomass in the photobioreactor. For a given aeration rate, the steady state biomass concentrati...

This study assessed the effects of nerve agent antidote (atropine/2-PAM chloride versus saline placebo) and heat-humidity (95 degrees F/60% RH versus 70 degrees F/30% RH) on repeated performance of militarily relevant psychological tasks while wearing the battle dress uniform (BDU) and while wearing chemical protective clothing (MOPP-IV). All BDU heat sessions (6 hours) were completed, but with...

The effect of disulfiram on the urotoxicity induced by ifosfamide was studied in mice. Ifosfamide administered intraperitoneally to mice caused a dose-related increase in bladder weight within 48 hr of treatment. Disulfiram prevented ifosfamide-induced bladder damage when administered orally within 1 hr of ifosfamide treatment. The results indicate that disulfiram is an effective protective age...

Here we demonstrated that SKI2162, a small-molecule inhibitor of the TGF-β type I receptor (ALK5), prevented radiation-induced fibrosis (RIF) in mice. SKI2162 inhibited phosphorylation of Smad and induction of RIF-related genes in vitro. In RIF a mouse model, SKI2162 reduced late skin reactions and leg-contracture without jeopardizing the acute skin reaction. Irradiation of mouse tissue increas...

To study the pharmacokinetics of single increasing intravenous doses (40-160 mg) and repeated doses (80 mg for 7 days) of lecithinized superoxide dismutase (PC-SOD) in Japanese volunteers and to compare the pharmacokinetics of PC-SOD between Caucasians and Japanese. The Japanese study consisted of 2 parts: a single-dose, open-label, dose-escalation part and a multiple-dose, single-blind, placeb...

OBJECTIVES The aim of this study was to describe outdoor workers' sun-protective practices, workplace sun-safety culture and sun-protective equipment provision; investigate the association of demographic, personal and occupational factors with sun-protective practices; and identify potential strategies for improving workers' sun protection. METHODS The present study used a clustered survey de...
