| [comparative biochemical studies of polyhedral proteins of nuclear polyhedrosis viruses]. | using disc polyacrylamide gel electrophoresis, the molecular weights of polyhedral proteins of nuclear polyhedrosis viruses (npv) of porthetria dispar, mamestra brassicae, and aporia crataegi were found to be 28000 +/- 3000. it was shown that npv polyhedra of bombyx mori, galleria mellonella, p. dispar, and m. brassicae contain a protease. during dissolution of the polyhedra at ph 10,5 this protease specifically cleaves the matrix protein into 2--5 fragments. the amino acid compositions of npv p ... | 1978 | 33725 |
| [protein metabolic change in the tissues of aporia crataegi l. under the action of the nuclear polyhedrosis virus]. | changes in protein metabolism in the hemolymph, fat body, intestine, and gonads of aporia crataegi l. caterpilars under the influence of nuclear polyhedrosis virus were studied. electrophoresis in polyacrylamide gel was used to study acid and basic proteins of insect tissues normally and after virus infection. the virus infection was shown to result in sharp changes of the protein spectrum of various tissues and organs, particularly 3 days after infection. the main changes consisted in the loss ... | 1979 | 380164 |

| [comparative analysis of the virion structural proteins of 3 nuclear polyhedrosis viruses]. | the composition of structural proteins of virions of nuclear polyhedrosis viruses (npv) of barathra brassicae l., lymantria dispor l. and aporia crataegi l. was studied by polyacrylamide gel-sds electrophoresis (page-sds). the object of the study included fractions of virion bundles in the envelope. all the baculoviruses under study were shown to have in virion structural proteins 23-24 polypeptides with molecular weights ranging from 12500 to 95000 daltons. alongside with polypeptides of simila ... | 1982 | 6760553 |
| [putrescine--an inhibitor of the reaction of carbon dioxide hydration in hemolymph of lepidoptera]. | using high-voltage electrophoresis, thin-layer chromatography and chemical analysis tetramethylene diamine was found in hemolymph of 8 lepidoptera species (bombyx mori l., ocneria dispar l., euproctis chrysorrhoea l., yponomeuta malinella l., pieris brassicae l., aporia crataegi l., melacosoma neustria l., mamestra brassicae l.). its content reaches 11 mm 1 l of hemolymph. the absence of tetramethylene diamine in the intestine wall and malpighian vessels and its presence in the fat body permits ... | 1980 | 6770522 |
| application of the nitroblue tetrazolium-reduction method for studies on the production of reactive oxygen species in insect haemocytes. | the in vitro generation of reactive oxygen species (ros) in haemocytes of galleria mellonella, aporia crataegi, dendrolimus sibiricus, aglais urticae (lepidoptera) and gryllus bimaculatus (orthoptera), was studied by the method of nitroblue tetrazolium (nbt) reduction. formazan formation (product of nbt reduction) was observed in haemocytes of all the insects examined, except a. urticae. lypopolysaccharide and zymosan reduced the number of nbt-positive cells after 1 h incubation and an increase ... | 2001 | 11545444 |

| [chemical composition and cryoprotective activity of ethanol extract from winter caterpillars aporia crataegi l]. | glycerol, alpha-carotene, and other yet unidentified compounds have been found in the ethanol extract from winter caterpillars of the black-veined white (aporia crataegi l.). we have shown that the ethanol extract has a cryoprotective effect on human peripheral blood lymphocytes, and this activity is approximately three times higher than that of glycerol (particularly, in the case of repeated freezing), which is one of the best cryoprotectors. | 2003 | 14735784 |

| combined effects of climate and biotic interactions on the elevational range of a phytophagous insect. | 1. the ranges of many species have expanded in cool regions but contracted at warm margins in response to recent climate warming, but the mechanisms behind such changes remain unclear. particular debate concerns the roles of direct climatic limitation vs. the effects of interacting species in explaining the location of low latitude or low elevation range margins. 2. the mountains of the sierra de guadarrama (central spain) include both cool and warm range margins for the black-veined white butte ... | 2008 | 18177334 |
| distribution of cytotoxic and dna adp-ribosylating activity in crude extracts from butterflies among the family pieridae. | cabbage butterflies, pieris rapae and pieris brassicae, contain strong cytotoxic proteins, designated as pierisin-1 and -2, against cancer cell lines. these proteins exhibit dna adp-ribosylating activity. to determine the distribution of substances with cytotoxicity and dna adp-ribosylating activity among other species, crude extracts from 20 species of the family pieridae were examined for cytotoxicity in hela cells and dna adp-ribosylating activity. both activities were detected in extracts fr ... | 2008 | 18256183 |
| molecular cloning of apoptosis-inducing pierisin-like proteins, from two species of white butterfly, pieris melete and aporia crataegi. | pierisin-1, present in cabbage butterfly, pieris rapae, induces apoptosis against various kinds of cancer cell lines. another cabbage butterfly, pieris brassicae, also has an apoptosis-inducing protein, pierisin-2. these proteins exhibit dna adp-ribosylating activity. pierisin-like proteins are found to be distributed in subtribes pierina, aporiina and appiadina. in this study, we performed the cdna cloning of pierisin-like proteins designated pierisin-3 from gray-veined white, pieris melete, an ... | 2009 | 19631761 |
