The Daily Rhythm of Activity of the Cockroach, Blatta Orientalis L. I. Aktograph Experiments, Especially in Relation to Light

IN the last few years there has been an increasing interest in animal rhythms. Various aspects of the subject have been reviewed by Szymanski (1920), Fox (1923), Hoffmann (1926), Richter (1927), AmirthaUngam (1928), Stein-Beling (1935), Scott (1936), Gunn et al. (1937), Pie'ron (1937) and Kalmus (1938a, b). This paper is concerned with the daily rhythm in the locomotory activity of the cockroac...

A molting rhythm for serum proteins of the cockroach, Blatta orientalis.

1. Polyacrylamide gel electrophoresis (PAGE) in 4% gels of Blatta orientalis larval hemolymph revealed 4 major proteins. 2. Maximum incorporation of [14C]-leucine into total hemolymph protein occurs within 24 hr and is followed by negligible turnover in the next 24 hr. 3. Quantitative PAGE was used to monitor concentration changes during the molting cycle in synchronously molting cultures. 4. A...

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Screening of antibacterial activity and biochemical assay from haemolymph of cockroach Blatta orientalis (Linnaeus, 1758)

The present study deals with the antibacterial activity of B. orientalis haemolymph against five bacterial strains namely, Pseudomonas aeruginosa, Proteus mirabilis, Staphylococcus aureus, Escherichia coli and Salmonella typhi. The results of the present study showed the maximum zone of inhibition against Escherichia coli, moderate effects were observed in Pseudomonas aeruginosa, Staphylococcus...
