1. Monoamines in the pedal plexus of the land snail Megalobulimus oblongus (Gastropoda, Pulmonata)
In molluscs, the number of peripheral neurons far exceeds those found in the central nervous system. Although previous studies on the morphology of the peripheral nervous system exist, details of its organization remain unknown. Moreover, the foot of the terrestrial species has been studied less than that of the aquatic species. As this knowledge is essentia

3. Especies tritiadas obtidas por irradiação de compostos de litio
The nuclear reaction Li(n,a)H occurs when compounds containing lithium are irradiated with neutrons. The resultant tritium atoms, after their high initial kinetic energy is thermalized, may react with ehemical species within the solid to produce new chemical bonds. When the irradiated compounds are dissolved in an aqueous solution, the various species contai

4. GLYOXYLATE METABOLISM IN GROWTH AND SPORULATION OF BACILLUS CEREUS1
Megraw, Robert E. (Iowa State University, Ames), and Russell J. Beers. Glyoxylate metabolism in growth and sporulation of Bacillus cereus. J. Bacteriol. 87:1087–1093. 1964.—Isocitrate lyase and malate synthetase were found in cell-free extracts of Bacillus cereus T. The patterns of synthesis of enzymes of the glyoxylic acid cycle were dependent upon the

7. γ-Aminobutyric Acid Pathway and Modified Tricarboxylic Acid Cycle Activity During Growth and Sporulation of Bacillus thuringiensis
Enzymatic analyses of Bacillus thuringiensis extracts suggested that a modified Krebs tricarboxylic acid cycle (without α-ketoglutarate dehydrogenase) can operate during sporulation in conjunction with the glyoxylic acid cycle and the γ-aminobutyric acid pathway.

8. Molecular Features Affecting the Biological Activity of the Host-Selective Toxins from Cochliobolus victoriae1
The structures of the toxins produced by Cochliobolus victoriae, victorin B, C, D, E, and victoricine, have recently been established. These toxins and modified forms of victorin C were tested for their effect on dark CO2 fixation in susceptible oat (Avena sativa) leaf slices. Half-maximal inhibition of dark CO2 fixation occurred with the native toxins in th

9. Homoaconitic Acid Accumulation by a Lysine-Requiring Yeast Mutant1
Homoaconitic acid, the second intermediate of the proposed pathway for lysine biosynthesis in yeast, is accumulated in the growth medium of a lysine-requiring mutant. This acid has been identified on paper and column chromatography by comparing it with authentic cis-homoaconitic acid. The infrared spectrum of the isolated material was identical with that of

10. Catabolism of indole-3-acetic acid and 4- and 5-chloroindole-3-acetic acid in Bradyrhizobium japonicum.
Some strains of Bradyrhizobium japonicum have the ability to catabolize indole-3-acetic acid. Indoleacetic acid (IAA), 4-chloro-IAA (4-Cl-IAA), and 5-Cl-IAA were metabolized to different extents by strains 61A24 and 110. Metabolites were isolated and analyzed by high-performance liquid chromatography and conventional mass spectrometry (MS) methods, including

11. Role of heterotrophic bacteria in complete mineralization of trichloroethylene by Methylocystis sp. strain M.
Biodegradation experiments with radioactively labeled trichloroethylene showed that 32% of the radioactive carbon was converted to glyoxylic acid, dichloroacetic acid and trichloroacetic acid and that the same percentage was converted to CO2 and CO after 140 h of incubation by a pure culture of a type II methane-utilizing bacterium, Methylocystis sp. strain

12. Prolonged survival of bovine adrenal chromaffin cells in rat cerebral ventricles.
Dispersed, cultured bovine adrenal chromaffin cells transplanted into the cerebral ventricles of neonatal and adult rats survived at least 2 mo without evidence of immunological rejection. The cells can be identified by their strong yellow fluorescent reaction with glyoxylic acid, which suggests that they maintain intact the capability of synthesizing and st
