    Summary Nitric oxide (NO) is a free radical synthesized from l-arginine by a family of NO synthase (NOS) enzymes, all of which are present in the skin, and also by reduction of sweat nitrate. NO synthesis is regulated by NOS activation (eNOS and nNOS) or synthesis (iNOS) and by substrate availability. Elevated arginase concentrations in psoriatic skin suggest that substrate competition may affect NO production. The balance of NO and reactive oxygen species is probably also important in regulating the biological actions of NO. The physiological functions of NO in the skin are being elaborated. NO release is increased following exposure to ultraviolet radiation (UVR); in eNOS null mice, dermal and epidermal apoptosis following UVR exposure is increased. Experiments in which keratinocytes and melanocytes were cocultured show melanogenesis being dependent on keratinocyte-generated NO, and UVR-induced guinea pig pigmentation is delayed following application of a NOS antagonist to the skin. Wound healing is delayed in eNOS and iNOS null mice.

    Notes:
    Results from two trials with normal and brown midrib-3 (bm3) types of LG11, Inra 188, Inra 240 and Inra 258 showed the bm3 mutant gene delayed silking by an average of 3 days, decreased whole plant dry matter (DM) concentration by 20 g kg−1 and the proportion of ear by 4·6 percentage units. Comparable yields of DM were obtained from normal and bm3 crops. The organic matter digestibility and yield of digestible organic matter of the bm3 plants was 0.06 units and 14% higher respectively than their normal counterparts.Measurement of the physical strength and resistance to lodging of normal and bm3 plants showed the bm3 gene reduced stem strength, which was highly correlated to stem diameter, stem weight and rind thickness. However, the major difference in plant lodging was between genotypes with Inra 240 plants less resistant to lodging than other genotypes. These results show that although the bm3 gene slightly increased lodging, genotype susceptibility is the major contributing factor to plant lodging.

    Notes:
    Sixty multiparous Holstein/Friesian cows were used in a 2 × 2 factorial design trial to determine the effect of the administration of bovine somatotropin (BST), at either 60 or 120 ± 3 d post partum, on milk production. All cows were offered ad libitum a forage mixture containing, on a dry-mailer (DM) basis, grass and maize silage in a 1:1 ratio and 4 kg d−1 fresh weight of concentrate, which contained 115 and 495 g kg−1 DM of neutral detergent fibre (NDF) and crude protein (CP), respectively, and 13–5 MJ kg−1 DM metabolizable energy (ME). BST-treated cows received subcutaneous injections of a prolonged-release formulation of BST (sometribove). Injections were administered into the ischiorectal fossa at 14-d intervals for the remainder of the lactation. This schedule resulted in sixteen and twelve injections cow−1 when treatment w as in it rate d at 60 and 120 + 3 d post partum respectively. This corresponded to treatment periods of 32 and 24 weeks, in which the production responses were measured. When compared with control cows, the administration of BST from 60 and 120 ± 3 d post partum increased mean milk yield by 1–2 and 3.3 kg day−1 respectively, although only the latter milk-yield response was significant (P 〈0.001). The administration of BST produced a small nonsignificant increase in DM intake, no effect on milk composition and a small but significant reduction in body condition In conclusion a significant milk-yield response can be obtained from the use of BST in high-forage, low-concentrate feeding systems if forage quality is high and treatment initiation is delayed until mid-lactation. This is illustrated by the fact that the lactation yield increased from 6054 to 6842 kg. and was obtained when using only 1.2 t of concentrate.

    Notes:
    Thirty-six British Friesian heifers were divided into two groups during weeks 3-26 of lactation and received ad libitum either good (G) or average (A) quality grass silage. The in vitro digestible organic matter in the DM was 680 and 600 g kg-1 for silages G and A, respectively. In addition, the heifers in each group were offered concentrate at either a low (4.3 kg DM d-1), medium (64 kg DM d-1) or high (8.4 kg DM d-1) level. The concentrate contained 180 g (kg DM)-1 of crude protein and had a calculated metabolizable energy concentration of 12.9 MJ (kg DM)-1.Increasing concentrate level significantly increased milk yield (P 〈 0.01), milk protein concentration (P 〈 0.05), and yield of both milk protein depressed milk fat concentration (P 〈 0.001) and silage intake (P 〈 0.001).Although the overall effect of silage quality on milk yield was not significant, the milk yields for silage G at each concentrate level were higher, significantly so for low level, than the corresponding values for silage A. An improvement in silage quality did not affect milk fat concentration but significantly increased the concentration of milk protein (P 〈 005) and yields of both milk fat (P 〈 005) and protein (P 〈 0001). The response of silage DM intake to improved silage quality was 0 06 kg DM per 10 g rise in vitro DOMD value. Each additional kg concentrate DM depressed intake of silages G and A by 0-63 and 0-27 kg DM, respectively. Substitution rate was also significantly related to stage of lactation.With both silages, the digestibility coefficients determined in vivo for acid detergent fibre (ADF) decreased significantly (P 〈 0.001) when concentrate level was increased from low to high. Differences for DM, OM and total N digestibility coefficients between treatments were not established as significant at the 5% level.Estimates of mean efficiency of utilization of ME for lactation, made on a weekly basis, were 049 and 052 for the heifers given silages G and A. respectively, and 048, 052 and 052 for those given the low, medium and high levels of concentrate. Energy balances were calculated on a mean weekly basis.

    We describe a woman who developed bullous pemphigoid in association with penicillamine therapy. While pemphigus is a well-recognized complication of penicillamine, pemphigoid should also be considered in the differential diagnosis of bullous eruptions induced by this drug.

    Notes:
    We report on the use of Rutherford backscattering spectroscopy for thickness analysis of organic light-emitting diode structures (OLEDs) with subnanometer resolution and a spatial resolution 〈1 mm. A careful study of ion beam induced effects revealed some organic film degradation, but not so severe as to inhibit meaningful measurements. The method is independent of the substrate and is still applicable if the organic film is capped with a metal cathode. Common OLED materials have been the subject of this study: poly(2-methoxy,5-(2′-ethylhexoxy)-1,4-phenylene-vinylene (MEH-PPV), N′,N′-diphenyl-N, N′-bis(3-methylphenyl)-1,1′ biphenyl-4,4′-diamine (TPD), and tris-(8-hydroxyquinoline) aluminum (Alq3). The densities of thin films of evaporated TPD (ρ=1.22±0.05 g/cm3) and Alq3 (ρ=1.51±0.03 g/cm3) have been established. © 1998 American Institute of Physics.

    Notes:
    The nitrogen content of SiO2/SiC (4H) structures annealed in NO and N2O has been measured using nuclear reaction analysis. Samples were annealed in 15N18O or 15N2O at 1000 °C at a static pressure of 10 mbar for either 1 or 4 h. Annealing in N2O incorporates ∼1013 cm−2 of N and annealing in NO incorporates ∼1014 cm−2, both of which are an order of magnitude lower than in SiO2/Si. In the NO anneal, N is predominantly incorporated near the SiO2/SiC interface with an atomic concentration of ∼0.5%. As in the nitridation of SiO2/Si, two features are observed in SiO2/SiC after the NO anneal: a surface exchange of O in the oxide with the gas phase and NO diffusion and reaction at the interface. The surface exchange reaction in SiO2/SiC is similar to SiO2/Si, but there is a large difference in the incorporation of N at the interface. © 2000 American Institute of Physics.

    Notes:
    Summary Nitric oxide (NO) is synthesized by many cells in the body. Low concentrations of NO have homeostatic roles in the circulation and nervous system, whereas high concentrations are biocidal, cytocidal and have immunomodulatory roles. The place of NO in the skin has recently become the focus of much attention, and this review highlights studies on the part played by NO in health and disease.

    Notes:
    Ten commercial varieties of winter wheat were sampled at different stages of growth, and dry mailer (DM) yields and potential nutritional quality, as determined by modified acid detergent fibre concentration (MADF), were measured. Maximum yields for the different varieties were spread over a four-week period, when the DM content was above 350 g kg−1. When the varieties were harvested for conservation as either fermented (DM 380 g kg−1) or alkaline (DM 580 g kg−1) whole crop, the mean MADF concentration was similar at both harvests, with large differences recorded between varieties. At both harvests the quality of the crops was sharply increased by raising the cutting height from 10 to 40 cm above ground level.
