the present study was performed to evaluate the analgesic effect of morphine microinjection into the cuneiformis nucleus (cnf) and the effect of inactivation of this area by lidocaine on pain modulation. rats were anaesthetized by thiopental (45-60 mg/kg/i.p.) and placed in a stereotaxic instrument, and then a guide cannula was implanted just one mm above the cnf. following surgery and recovery...

In vertebrates, PDGFA and its receptor, PDGFRalpha, are expressed in the early embryo. Impairing their function causes an array of developmental defects, but the underlying target processes that are directly controlled by these factors are not well known. We show that in the Xenopus gastrula, PDGFA/PDGFRalpha signaling is required for the directional migration of mesodermal cells on the extrace...

Virus spillover from managed to unmanaged bees and vice versa may be one mechanism driving colony losses of the former declines latter. There is clear evidence that ubiquitous Deformed wing virus (DWV) a major driver honey bee ( Apis mellifera ) mortality. Although DWV has been detected in solitary Osmia bicornis , data on infectivity virulence are scarce. Here, we used microinjection investiga...

The melanocortin-4 receptor (MC4R) plays a critical role in homeostasis and the regulation of body weight. Polymorphisms mc4r gene have been discovered linked to growth, carcass composition, meat quality traits. Therefore, we used CRISPR-Cas9 system target most important freshwater aquaculture species USA, channel catfish, Ictalurus punctatus. Guide RNAs were designed direct Cas9 coding sequenc...

introduction: we previously shown that microinjection of glutamate into the hdb of rat elicited cardiovascular depressive responses. microinjection of ap5 (an nmda receptor antagonist, 2.5 mm, 50 nl) and cnqx (an ampa receptor antagonist, 1 mm, 50 nl) caused no significant changes in the blood pressure and heart rate. microinjection of bicuculline (bmi: a gabaa receptor antagonist, 1 mm, 50 nl)...
