In each year, ten genotypes from each species were evaluated with late season insects controlled with either methyl parathion or endosulfan insecticides, and without insecticides. Major late season insect damage in 1992 was caused by cabbage seedpod weevil (Ceutorhynchus assimilis Paykull), while diamondback moth (Plutella xylostella L.) and aphids (primarily cabbage aphids, Brevicoryne brassicae L.) were major insect pests in 1993. Insecticide application was very effective in controlling diamondback moth larvae and adult cabbage seedpod weevils, but only partially effective in controlling aphids. Higher numbers of diamondback moth larvae were observed on mustard species compared to canola species. S. alba was completely resistant to cab...

While it is established that estrogen affects the chronic inflammatory processes of coronary atherosclerosis, the effects of estrogen on acute myocardial proinflammatory signaling are unknown. To study this, myocardial ischemia and reperfusion was performed in rat hearts from normal adult males, normal adult females, ovariectomized (OVX) females, males supplemented with E2, and OVX females supplemented with E2. Following reperfusion, homogenized hearts were analyzed for TNF-a, IL-1b, and IL-6 gene and protein expression, p38 MAPK activation, and the apoptosis-related proteins caspase-3 and Bcl-2. Hearts from proestrus females demonstrated significantly better post-ischemic functional recovery than males. E2 supplementation to males and OVX females improved post-ischemic myocardial functional recovery, reduced the production of TNF-a, IL-1b and IL-6, and decreased the activation of p38 MAPK and caspase-3 when compared to their untreated counterparts. These results suggest that the effect of estrogen on cardioprotection against myocardial I/R may be attributed to its anti-inflammatory and anti-apoptotic properties. Further understanding of these mechanisms may allow therapeutic manipulation of sex hormones in the treatment of acute ischemic injury.
