The Hessian fly nutritive tissue probably acts as a sink tissue within the wheat seedling, benefiting the growth of larvae by importing photoassimilates, and is likely to be beneficial to R gene-defended plants.
Comparative carcinogenicity in Sprague-Dawley rats of the polychlorinated biphenyl mixtures Aroclors 1016, 1242, 1254, and 1260.
Liver toxicity was distinctly more severe in females than in males, and the incidence of hepatocellular neoplasms was highly sex-dependent, differed between Aroclor mixtures and, for females, increased with dose and followed the general incidence pattern.
Examination of bone marrow, immunologic parameters and host susceptibility following pre- and postnatal exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD).

Six separate chitinase genes from V. harveyi appear to be unique based on DNA restriction patterns, immunological data, and enzyme activity, and this marine bacterium and probably others appear to synthesize separate Chitinases for efficient utilization of different forms of chit in and chitIn by-products.
The comparative toxicity of chlorinated dibenzo-p-dioxins in mice and guinea pigs.
Impairment of thymus-dependent immune functions by exposure of the developing immune system to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD).
TCDD suppressed cell-mediated immune function without affecting humoral immune function and suppression of T-cell function was selective in that "helper" cell function was not suppressed.
The effect of age and exposure duration on cancer induction by a known carcinogen in rats, mice, and hamsters.
Comparative Carcinogenicity in Sprague-Dawley Rats of the Polychlorinated Biphenyl Mixtures Aroclors 1016, 1242, 1254, and 1260
Liver toxicity was distinctly more severe in females than in males, and the incidence of hepatocellular neoplasms was highly sex-dependent (females > males), differed between Aroclor mixtures and, for females, increased with dose and followed the general incidence pattern.
Teratology studies with 2,4,5-trichlorophenoxyacetic acid and 2,3,7,8-tetrachlorodibenzo-p-dioxin.
Suppression of cellular immunity in rats and mice by maternal treatment with 2,3,7,8-tetrachlorodibenzo-p-dioxin.
In contrast to the marked effects in early life, reduced responsiveness of spleen cells to PHA in mice treated with TCDD when 1 month old was only seen at a dose level that was clearly toxic, and in 4-month-old mice, PHA responsiveness as well as GVH activity were not decreased.
