    Notes: Abstract Background: Single-agent bi-weekly paclitaxel was studied as first-line metastatic treatment for breast cancer in a phase I–II trial. Patients and methods: Thirty-eight women with metastatic breast cancer were enrolled. Thirty-seven are evaluable for toxicity, 35 for response. Results: The MTD was defined at 160 mg/m2 q two weeks with dose limiting toxicity in two patients consisting of hematological toxicity (1) and neurotoxicity (2). Twenty patients were treated at 150 mg/m2, the recommended dose. Response rates were two CRs and nine PRs (overall 61%) at the RD of 150 mg/m2 and three CRs and 11 PRs for an overall RR of 67% for the two top doses. Conclusions: The good drug tolerance, response rates, and convenience over weekly treatment suggest this may be a worthwhile regimen.

    Description / Table of Contents: Résumé Anthocoris nemorum (L.) etA. nemoralis (F.) ont été élevés sur le stade aptère du puceron du houblon,Phorodon humuli (Schrank), à 20°C±0.5°C. A. nemorum etA. nemoralis ont consommé durant leur phase larvaire, en moyenne 255 et 174 pucerons respectivement, les adultes par contre ont consommé respectivement 37 et 33 pucerons par jour. Les jeunes larves consommaient de façon sélective les jeunes pucerons, tandis que les adultes et les larves au 5c stade consommaient des pucerons de toute taille. Le délai de développement entre l'émergence et la métamorphose finale pourA. nemorum etA. nemoralis fut de 22 et 16 jours respectivement.
    Notes: Abstract Anthocoris nemorum (L.) andA. nemoralis (F.) were reared on apterous hop aphids,Phorodon humuli (Schrank), at 20±0.5°C.A. nemorum andA. nemoralis killed an average of 255 and 174 aphids respectively during nymphal development, and the adults killed 37 and 33 per day respectively. Small anthocorid nymphs selectively killed small aphids but adult anthocorids and 5th instar nymphs killed aphids of every size. Mean development times from emergence to final moult were 22 and 16 days forA. nemorum andA. nemoralis respectively.

    Notes: Abstract We present the results of a microscopic theory of the scattering, transmission, and sticking of 4 He atoms impinging on a zero temperature 4 He slab at near normal incidence. The theory includes coupling between different modes and allows for inelastic processes. The present work focuses on the elastic reflection and transmission of a 4 He atom in the sense that we examine these intensities for atoms which have the same energy as the incident atoms. We find a considerable loss of total intensity due to scattering into multiple excitations. The reflected signal is in qualitative and semi-quantitative agreement with experimental results for 4 He atoms scattered from the surface of bulk helium. The transmission intensity — which has not been measured — shows a very strong energy dependence. Moreover, we show that this dependence is substantially different from the Feynman level theory, which doesn't permit the decay of the single excitation into multiple excitations, and thus cannot describe a reduction in total intensity. In our theory, the major source of decay of elastic transmission and reflection (i.e., sticking) is from the production of ripplons at the liquid-vacuum interfaces.

    Notes: Abstract Recent studies on the nature of global warming indicate the likelihood of an asymmetric change in temperature, where night-time minimum temperature increases more rapidly than the day-time maximum temperature. We used a physically based scenario of asymmetric warming combined with climate change scenarios from General Circulation Models (GCMs) outputs and the EPIC (Erosion Productivity Impact Calculator) plant process model to examine the effects of asymmetric temperature change on crop productivity. Our results indicated that the potential effects of global change on crop productivity may be less severe with asymmetric day-night warming than with equal day-night warming.

    Notes: Abstract Indicators of the condition and sustainability of agricultural lands in five Mid-Atlantic states were measured in 1994. Indicators were selected to reflect crop productivity and land stewardship on annually harvested herbaceous crop (AHHC) land, which covers almost 10% of the land area in this region. Overall, condition of agricultural lands in the region is good. Crops generally yielded more than those grown in the 1980s, with a mean observed/expected yield index greater than 1. The mean soil quality index was slightly better than a "moderate" rating for crop growth. Almost 2/3 of the AHHC land is covered by crop rotation plans, with the remaining land mostly in hay fields. Insecticides were applied to less than 20% of AHHC land, and less than 20% of the land where pesticides were applied has high to moderately high potential for pesticides leaching into groundwater. However, integrated pest management (IPM) is practiced on less than 20% of AHHC land. Hay showed more efficient use of nitrogen than seed crops, and non-tilled sites, which are mostly hay, had more microbial biomass (suggesting more nutrient cycling) than tilled sites. This information could provide a baseline for a long-term monitoring program for agroecosystems in the region.

    Notes: Summary A ten-year-old boy presented with a prolonged cholestatic liver disease 5 weeks after starting diphenylhydantoin therapy. The initial phase of his illness was characterized by hepatocellular damage with swollen liver cells and centrilobular cholestasis. Severe hyperlipoproteinemia with eruptive xanthomata developed within 3 weeks of his initial jaundice. The second phase of his illness was characterized by portal tract inflammation with bile ductular proliferation and chronic cholestasis gradually resolving over a period of 15 months. It is postulated that diphenylhydantoin sensitivity produced swollen hepatocytes with hypertrophy of the smooth endoplasmic reticulum, reducing hepatic sinusoidal blood flow and the clearance of secondary bile salts. A fall in clearance of lipoproteins, including the cholesterol precursor of primary bile acid synthesis, may have been responsible for a reduction in serum bile acid concentration. High levels of serum lithocholic acid, largely unsulfated presumably due to decreased hepatic uptake, may have produced the prolonged second phase of this illness when histological changes resembled that seen in experimental animals following lithocholic acid administration.
