The external morphology of the antennal sensilla of Pteromalus puparum females (Hymenoptera: Pteromalidae) is described using scanning electron microscopy. The antennae of P. puparum females are geniculate in shape, formed from a large, cylindrical scape with a basal radicel fitting into the antennal socket, a shorter, barrel-shaped pedicel and a flagellum composed of 12 subsegments. Eight morphologically...
The physiological performance and ultrastructural integrity of the vegetative freshwater green alga Zygnema sp., growing under ambient polar day solar radiation and after exposure to experimentally low radiation, but with high UVR:PAR ratio were investigated. In the laboratory, algae were exposed to low photosynthetic active radiation (PAR=P, 400–700nm, 20μmolm −2 s −1 ), PAR+UV-A=PA...
Confocal fluorescence imaging and fluorescence resonance energy transfer (FRET) technology have been widely used to study protein–protein interactions in living cells. However, it is very difficult to quantitatively analyze FRET efficiency due to the excitation spectral crosstalk and emission spectral crosstalk between donor and acceptor. In this study, we developed a novel method to quantitatively...
Animal models of bronchial hyperresponsiveness have been successfully used to investigate the pathophysiology of asthma. When mice are sensitized and challenged with an allergen, such as OVA, they experience symptoms and processes similar to that of humans, and are therefore widely used as asthmatic animal models. In the current study the BALB/c murine asthmatic animal model was used to investigate...
