    An ultrastructural study of spontaneous mineralization in the brains of aging mice (1982)

    Notes: Summary Spontaneous mineralization observed in the thalamus, and meninges of the median longitudinal fissure, of several strains of mice was studied by light and electron microscopy. The mineralized deposits were closely associated with blood vessels, were periodic acid-Schiff positive, and contained variable amounts of calcium. The thalamic deposits were found to be in an extra-cellular location, and consisted of a randomly arranged mass of fine fibrils or spicules, with laminations of varying electron density in larger deposits. The deposits appeared to develop on the surface of subendothelial and medial, vascular basement membranes. Energy dispersive, X-ray microanalysis demonstrated the presence of both calcium and phosphorus in small and large deposits.

    Field Calibration of a Capacitance Water Content Probe in Fine Sand Soils (1999)

    Notes: v ) of 〈0.10 cm3 cm-3 after drainage due to gravity has ceased. Small changes in θv in the range of 0.02 to 0.08 cm3 cm-3 can greatly affect plant available water and, therefore, good calibration of soil water content sensors is necessary. The EnviroSCAN (Sentek Pty. Ltd., South Australia) is a multiple sensor capacitance probe capable of continuous measurement of soil water content by volume (θv). Many fine sand soils in Florida have plant available θv values of ≤0.08 cm3 cm-3. The manufacturer's calibration curve has very few data points 〈0.10 cm3 cm-3θv and no data in the 0.02 to 0.04 cm3 cm-3θv range. Because of the lack of data in this range, a calibration curve from 0.02 to 0.08 cm3 cm-3θv was developed for Candler fine sand (hyperthermic, uncoated Typic Quartzipsamments), Apopka fine sand (loamy, siliceous, hyperthermic Grossarenic Paleudults), and Immokalee fine sand (sand, siliceous, hyperthermic Arenic Alaquods) in two locations in Florida. Since calibration curves for the three soils did not differ significantly, data from the three soils were combined. An exponential calibration curve was developed (RMSE = 0.0085, R2 = 0.83). This equation provides substantially different estimates of water content in the 0.02 to 0.08 range than values obtained from the manufacturer's calibration. This improved calibration extends the range of the EnviroSCAN to include an important group of soils with very low water holding capacity.

    Notes: summary The14C-labelled, substituted benzamide neuroleptic Tiapride has been found to accumulate transiently in the pituitary gland of the rat following a single dose, and a prolonged retention of the drug was observed in the pars intermedia.

    Notes: Summary Mexican lime seedlings were inoculated with 0, 500, 1000, 2000, 4000 and 8000 microconidia ofFusarium oxysporum f. sp.citri per gram of potting media. The percent infection and mean disease severity rating increased with increasing inoculum density of the pathogen. In potting mix infested withAspergillus ochraceus, Penicillium funiculosum andTrichoderma harzianum at 5000 conidia per gram 2 weeks prior to infestation withF. oxysporum f. sp.citri at 0, 1000, 4000, and 8000 microconidia per gram,A. ochraceus reduced,P. funiculosum increased andT. harzianum had no effect on disease severity or pathogen population. OnlyP. funiculosum showed antagonistic activityin vitro against the pathogen. Disease severity and pathogen propagule densitites were greater and pH was lower in potting media fertilized with NH4−N than in media fertilized with NO3−N.
