    Notes: Summary Twenty-four hours after a tetracycline injection, the unimpeded, and more rapidly erupting, mouse mandibular incisor contained 20% to 44% more tetracycline than the contralateral, uncut incisor. It was concluded that the increased tetracycline incorporation reflected a higher rate of mineralization associated with faster tooth formation in the unimpeded tooth. By measuring the amount of tetracycline which became incorporated at different times after an incisor was shortened, it was possible to investigate an early stage of the response of the incisor to cutting. A significant increase in the capacity of the tooth to incorporate tetracycline was detectable 4 h after shortening the tooth, and this was maximal after another 4 h.

    Characterization and orientation of adsorbed NO dimers on Ag{111} at low temperatures (1995)

    Notes: Reflection-absorption infrared spectroscopy (RAIRS) and near-edge x-ray absorption fine structure (NEXAFS) have been used, with isotopic 14NO/15NO mixtures, to determine the structure and orientation of the monolayer species formed by NO adsorption on Ag{111} at 40 to 60 K. The adlayer is composed of NO dimers bonded with the N–N axis in the surface plane and with the molecular plane tilted away from the surface normal by about 30°. This structure provides a simple basis for understanding the facile reaction to adsorbed N2O and O which occurs on heating to 70 to 90 K. © 1995 American Institute of Physics.

    NO monomer and (NO)x polymeric chain chemisorption on Pt{110}: Structure and energetics (1999)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: The chemisorption of NO on Pt{110}-(1×1) and -(1×2) has been studied using density functional theory slab calculations with the generalized gradient corrections. On both surface phases the monomeric species is the most stable and the short-bridge sites are energetically the most favorable adsorption sites. Monomeric NO is adsorbed upright with its molecular axis normal, bonded to the surface through the N atom. On the (1×2) surface at high coverage a polymeric (NO)x chain structure is identified; this may well correspond to the structure experimentally observed at high coverage on the (1×2) surface formed after heating a multilayer to temperatures between 80 K and 200 K, characterized by an NO IR band at 1760 cm−1. © 1999 American Institute of Physics.

    Notes: A method for measuring the transverse inclination of molar teeth is described which enabled significant differences (P 〈 0·001) between the three molars to be demonstrated for a sample of English Modern (n 24) and Romano-British (n 20) skulls.No significant differences between the transverse molar inclinations were found for the Bronze Age (n 10) or the Neanderthal (n 8) sample.

    Development of High-Protein Low-Cost Nigerian Foods (1983)

    Notes: Nigerian foods, akara, chin-chin, and puff-puff, were supplemented with full-fat cottonseed, defatted cottonseed, peanut, sesame or soybean flours. The foods were evaluated using a nine-point Hedonic scale by African and non-African panels. Foods were evaluated for appearance, texture, absence of greasiness, palatability and overall acceptability. The African panel rated all food products for all characteristics significantly (P=0.001) higher than the non-African panel. Protein quality evaluations indicated that full-fat cottonseed, defatted cottonseed and defatted peanut flours could be used to increase the quantity and quality of protein in traditional Nigerian foods.

    Acetylcholine and affective disorder (1987)

    Notes: Summary We reviewed the evidence for involvement of central cholinergic neurons in affective disorder. Cholinomimetics inhibit speech, thought, and activity in most subjects, decrease manic symptoms and, in some affective disorder patients, produce depressive symptoms. Cholinomimetics also cause ACTH and cortisol secretion and decrease latency to REM sleep. It is unclear whether cholinomimetics are specifically “antimanic” or “depressogenic” or whether their fundamental effect is nonspecific behavioral inhibition; whether the observed effects of cholinomimetics are mediated largely through cholinergic pathways, are secondary to changes in other neurotransmitters or are part of a nonspecific stress response. The suggestion that anticholinergic agents have mood elevating properties has not yet been subjected to controlled investigation. Although the proposal that affective disorders involve cholinergic neurons has received some support from clinical investigation further research is required to substantiate the intriguing observations to date and to clarify the physiologic and psychologic processes mediating them.

    Stability of serum neuroleptic and prolactin concentrations during short- and long-term treatment of schizophrenic patients (1987)

    Notes: Abstract The potential importance of neuroleptic activity measures in the management of schizophrenia warrants attention to the methods for assessing neuroleptic bioactivity and stability of neuroleptic bioactivity over time. We have carried out measurements of serum neuroleptic and prolactin concentrations in 18 schizophrenic patients treated with haloperidol or thioridazine for up to 1 year. Serum neuroleptic levels were measurd by a radioreceptor assay using porcine striatum. The lower limit of sensitivity of the assay was 0.6 ng haloperidol/ml, the intra- and interassay coefficients of variation 3 and 9%, respectively. A linear correlation was observed between haloperidol dose (5–30 mg/d) and serum neuroleptic activity (r=0.706, P〈0.001) and a curvilinear relationship between thioridazine dose (50–600 mg/d) and serum neuroleptic activity in schizophrenic outpatients. There was a positive correlation between serum neuroleptic and prolactin concentrations for the patients taking haloperidol (r=0.620, P〈0.001) or thioridazine (r=0.542, P〈0.001). In patients taking a constant dose of haloperidol or thioridazine for up to 1 year serum neuroleptic activity remained stable, suggesting the absence of metabolic tolerance; the observation of a decrease of 38±16% (mean ± SD) in serum prolactin concentrations in patients treated with haloperidol but no prolactin decrease with thioridazine suggests that under certain neuroleptic treatment conditions a functional tolerance develops in the tuberoinfundibular dopamine system.

    Transport and containment of plasma, particles and energy within flares (1983)

    Notes: Abstract Results from the analysis of flares observed by the Solar Maximum Mission (SMM) and a recent rocket experiment are discussed. We find evidence for primary energy release in the corona through the interaction of magnetic structures, particle and plasma transport into more than a single magnetic structure at the time of a flare and a complex and changing magnetic topology during the course of a flare. The rocket data are examined for constraints on flare cooling, within the context of simple loop models. These results form a basis for comments on the limitations of simple loop models for flares.
