A three-year field monoculture trial of Radix pseudostellariae and complementary laboratory studies were conducted to further elucidate the underlying mechanism responsible for significant decreases in the biomass yield and quality of R. pseudostellariae under continuous monoculture regimes. HPLC
Inorganic phosphate exchanges between plasma and sciatic nerve have been measured in the rabbit using a 32PO4 tracer technique. Inorganic phosphate is taken up at the rate of 0.13 microng per hour and per 100 mg fresh weight. Incorporation of plasma radiophosphate is markedly increased into the
Plasma inorganic phosphate incorporation into inorganic and organic acid soluble phosphate fractions of the rat sciatic nerve shows, for one week after the operation, parallel increases in both crushed and sectioned nerves. After two weeks the incorporation in the distal part of the crushed nerve
Active transport of organic acids (ATOA) in proximal renal tubules of Campbell, Wistar and random-bred rats was studied by contact microfluorometry with anion fluorescein as a marker. Beginning with the 60th day of life this transport in Campbell rats was characterized by a lower equilibrium uptake
Mutations in POLG account for one of the most frequent nuclear encoded causes of mitochondrial disorders to date. Individuals harboring POLG mutations exhibit fairly heterogeneous clinical presentations leading to increasing difficulties in classifying these patients into defined clinical
Digesters produce biogas from organic wastes through anaerobic digestion processes. These digesters, often made of concrete, suffer severe premature deterioration caused mainly by the presence of fermentative microorganisms producing metabolites that are aggressive towards cementitious materials. To
A girl of first cousin parents presented in the 1st year of life with a progressive neurological disease with muscle weakness and hypotonia, accompanied later by dystonia. Investigations, including gas chromatography of urine, showed no abnormality. Autopsy showed marked neuronal loss and gliosis in
Plasma inorganic phosphate incorporation into inorganic and organic acid-soluble phosphate fractions of the rat sciatic nerve increases markedly during Wallerian degeneration. Administration of cycloheximide and actinomycin D remains without effect on this specific increase which appears thus
A new method that allows organic acid selectivity to be dynamically controlled during gas chromatography (GC) is presented. It employs dual in-series stainless steel columns, each coated with a pH-adjusted water stationary phase. The first is a 2 m column coated with a pH 11.4 phase that is
Oleic and malonic acids were found in control samples while p-nitroaniline addition induced production of tricarballylic acid in eight and twelve days exposed samples. Fumaric and citric acids were found in sporadic instances. Addition of p-phenylene diamine to the mixture showed a degeneration
Confronted with the gradual exhaustion of the earth's fossil energy resources and the grimmer environmental deterioration, the bio-based process to produce high-value added platform chemicals from renewable biomass is attracting growing interest. Escherichia coli has been chosen as a workhouse for
Changes in sugars, organic acids and volatile compounds (VC) of red pepper flakes (RPF), traditional (TRI), and industrial (INI) isot peppers were evaluated during one year storage at the room condition. The changes in the flavor components were significantly affected by the production methods and
