Studies on the Posterior Silk Gland
Cytolytic processes in posterior silk gland cells of the silkworm, Bombyx mori, during metamorphosis from larva to pupa have been studied. During this stage, the wet weight and the amounts of RNA and protein of the gland decrease rapidly and markedly, while the amount of DNA decreases slowly and slightly. The ultrastructural changes observed at the beginning of the prepupal stage consist of the...
متن کاملThe effect of incubation time and silk worm cocoon on mobility of zinc and copper in contaminated clay soil
Of the problematic agents in the ecosystem, heavy metals have special importance because they are unabsorbable and have physiologic effects on living beings at low concentrations. This study has investigated the effect of silk worm cocoon on reducing mobility of zinc (Zn) and copper (Cu) for the first time. To this end, 5% cocoon adsorbent was added to the studied soil, which had been contamina...
متن کاملSilk worm Bm1 SINE RNA increases following cellular insults.
The effect of cell stresses upon the expression of the Bm1 short interspersed element (SINE) family in cultured silk worm cells is examined. Primer extension analysis shows that Bm1 repeats are transcribed by RNA polymerase III (Pol III) into cytoplasmic RNAs. Five consecutive T residues, which would normally terminate Pol III transcription, occur within the Bm1 consensus and are included withi...
متن کاملStudies on the Metabolism of the Filarial Worm, Litomosoides Carinii
The filarial worm, Litomosoides carinii, has a high rate of aerobic and anaerobic glucose metabolism. Aerobically 30 to 45 per cent of the glucose utilized was converted to lactic acid, 25 to 35 per cent to acetic acid, and 10 to 20 per cent to a polysaccharide. Anaerobically over 80 per cent of the total carbohydrate removed by the filariae was metabolized to lactic acid, the remainder was acc...
