    Notes: Abstract A laboratory study was conducted to compare the effects of different N fertilizers on emission of N2 and N2O during denitrification of NO3 – in waterlogged soil. Field-moist samples of Drummer silty clay loam soil (fine-silty, mixed, mesic Typic Haplaquoll) were incubated under aerobic conditions for 0, 2, 4, 7, 14, 21, or 42 days with or without addition of unlabelled (NH4)2SO4, urea, NH4H2PO4, (NH4)2HPO4, NH4NO3 (200 or 1000 mg N kg–1 soil), or liquid anhydrous NH3 (1000 mg N kg–1 soil). The incubated soil samples were then treated with 15N-labelled KNO3 (250 mg N kg–1 soil, 73.7 atom% 15N), and incubation was carried out under waterlogged conditions for 5 days, followed by collection of atmospheric samples for 15N analyses to determine labelled N2 and N2O. Compared to samples incubated without addition of unlabelled N, all of the fertilizers promoted denitrification of 15NO3 –. Emission of labelled N2 and N2O decreased in the order: Anhydrous NH3〉urea〈$〉\gg〈$〉 (NH4)2HPO4〉(NH4)2SO4≃NH4NO3≃NH4H2PO4. The highest emissions observed with anhydrous NH3 or urea coincided with the presence of NO2 –, and 15N analyses indicated that these emissions originated from NO2 – rather than NO3 –. Emissions of labelled N2 and N2O were significantly correlated with fertilizer effects on soil pH and water-soluble organic C.

    Theory and simulation of the swelling of polymer gels (2000)

    Notes: A combined discontinuous molecular dynamics and Monte Carlo simulation technique is used to study the swelling of athermal, continuous-space, near-perfect, trifunctional polymer networks containing hard chains of lengths 20 and 35 immersed in an athermal hard-sphere solvent. The swelling simulations are conducted under conditions of constant pressure and chemical potential. A simple, analytical theory for gel swelling is presented in which the gel free energy is calculated as the sum of an elastic, affine-type term, and a liquidlike mixing term that is based on the generalized-Flory dimer equation of state. The theory shows good agreement with our simulation results for the gel properties at swelling equilibrium. © 2000 American Institute of Physics.

    Pressure–volume properties of endlinked hard-chain polymer networks (1999)

    Notes: Equilibrium molecular dynamics simulations are used to obtain the pressure and configurational chain properties of near-perfect, off-lattice, trifunctional hard-chain networks of chain lengths 20, 35, 50, and 100, and of tetrafunctional hard-chain networks of chain lengths 20, 35, and 50 over a range of packing fractions. Our simulation results show that the variation of network pressure with density is similar to that of uncrosslinked chain systems of the same chain length, except at low densities where the network pressure shows a negative region, as first observed by Escobedo and de Pablo. We present a theoretical treatment leading to an analytical expression for the network pressure as the sum of liquid-like and elastic contributions. The liquid-like contribution is obtained by extending the generalized Flory-dimer theory to networks, and the elastic contribution is obtained by treating the network as a set of interpenetrated dendrimers and using an ideal chain-spring analogy to calculate the free energy. The theoretical predictions for network pressure are in good agreement with simulation data. © 1999 American Institute of Physics.

    Random Fine Needle Aspiration of the Breast of Women at Increased Breast Cancer Risk and Standard Risk Controls (1998)

    Notes: Abstract: The diagnosis of occult breast epithelial proliferation by random fine needle aspiration biopsy (FNAB) of the breast remains controversial. However, the detection of proliferative change using FNAB would potentially improve assessment of breast cancer risk among women entering chemoprevention trials. To assess the validity of this procedure in risk stratification for breast cancer, we performed FNAB on 70 women while they were anesthetized for a variety of general surgical procedures. The contralateral breasts of 32 women with a history of breast cancer (cases) and both breasts of 38 women at standard risk for breast cancer (controls) were subjected to random FNAB. Cytospin preparations from four pooled FNAB passes from each breast were stained by the papanicolaou technique and interpreted according to previously published criteria. Inadequate aspirates comprised 40% (28/70) of the samples. In the remaining cases, there was a statistically significant difference between the frequency of proliferative changes and atypical hyperplasia in high-risk cases versus controls (Pearson χ2= 9.98, p = 0.019). The contralateral breasts of women with sporadic breast cancer demonstrated proliferative changes at higher rates than breasts of asymptomatic control women. Similarly, in a logistic regression model, the odds of a diagnosis of breast cancer increased with the presence of proliferative changes with or without atypia [odds ratio (OR) = 3.6, p 〈 0.02]. This study suggests that FNAB may have a role in the further stratification of high-risk women and provide a suitable sample for the monitoring of surrogate end point biomarkers in chemoprevention trials.

    Notes: Summary— Experience with tetracosactrin-depot therapy in 10 patients with dermatological disorders is described. The clinical response was considered good in 7 patients, poor in the remaining 3. Plasma cortisol levels remained elevated 24 to 48 hr. following injection but there were considerable differences between patients in both the magnitude and duration of response.Melanoderma and other side effects were troublesome when the total weekly dose exceeded 1 mg. Smaller dosages gave satisfactory response without significant accompanying side effects.
