Characterization of recombinant per a 10 from Periplaneta americana.
Cockroach allergen is a major risk factor for IgE-mediated allergic response and asthma in sensitized individuals. Serine proteases have been identified from various sources and characterized as major allergens. The present study was aimed to express and characterize recombinant allergen Per a 10 (rPer a 10) from Periplaneta americana. rPer a 10 was expressed in Escherichia coli and purified in...
متن کاملEvidence of poly(ADP-ribosylation) in the cockroach Periplaneta americana.
Poly(ADP-ribosylation) is a post-translational modification of nuclear proteins typical of most eukaryotic cells. This process participates in DNA replication and repair and is mainly regulated by two enzymes, poly(ADP-ribose) polymerase, which is responsible for the synthesis of polymers of ADP-ribose, and poly(ADP-ribose) glycohydrolase, which performs polymer degradation. The aim of this wor...
متن کاملOrganization of the giant axons of the cockroach Periplaneta americana.
Several authors have reported the presence of ascending giant fibres (AGF) in the nerve cord of the American cockroach, Periplaneta americana (Pumphrey & Rawdon-Smith, 1937; Roeder, 1948; Hess, 1958). Roeder (1948) presented a scheme showing a synaptic link (in the 6th abdominal ganglion) between the cereal sensory neurones and the AGF, the latter then ascending as continuous fibres to the meta...
متن کاملLaboratory evaluation of fipronil against Periplaneta americana & Blattella germanica.
BACKGROUND & OBJECTIVE In cockroach control, bait formulations are extensively used. Fipronil is one of the broad spectrum insecticides from phenyl pyrazole family available in bait formulation. The compound has been tested under field conditions. However, information on its effectiveness on different surfaces and at various density levels is not known. Therefore, the efficacy of a new formulat...
متن کاملSpatial learning in the restrained American cockroach Periplaneta americana.
Spatial learning abilities were tested in restrained cockroaches by observing antennal projection responses towards the positions of a learned visual cue perceived monocularly by one eye in the context of a second stimulus provided to the contralateral eye. Memory of the position of the conditioning stimulus relative to the contralateral reference stimulus was tested by altering the relative po...
