microinjection

a method for introducing new DNA into a CELL by injecting it directly into the NUCLEUS or CYTOPLASM using a thin glass needle. The technique has been used to inject cloned genes into the nucleus of an egg cell in vitro, to generate a TRANSGENIC ORGANISM.

(7) that VUF-8430 microinjection into the cerebellar vermis induced an inhibitory effect on memory consolidation in the EPM and IAT models, this study aimed to investigate whether VUF-8430 induces activation of CREB and phosphorylated CREB (pCREB) in the following structures: cerebellar vermis, prefrontal cortex (PFC), amygdala, and hippocampus.
Effects of the Microinjection of Saline into the Cuneiform Nucleus on Blood Pressure and Heart Rate
From the effects of the unilateral microinjections of PZP and MTC on ovulation, we suggest that the number and affinity of [m.sub.2]AChR are higher on dioestrous-2 than on the day of oestrous, while [m.sub.1]AChR predominates on the day of oestrous, even when the number of cells positive for mAChR is unchanged at 13:00 h on dioestrous-2 and on the day of oestrous.
Microinjections of ET-1 Caused Focal Striatal Damage and Acute Inflammatory Response, Which Were Reduced by Both BMMC Transplantation and Minocycline Treatment.
Before testing the effects of different microinjections into the RVLM, the functional pressor sites were identified by bilateral glutamate microinjection into the region (0.1 mol/L, 100 nL).
In conclusion, in this study we observed that intra-MRN microinjections of xanthone, as well as the 5-[HT.sub.1A] antagonist, [Way.sub.100635], reduced immobility time in the FST model.
It was observed that while microinjection of cholinergic agonist, carbachol, into the medio-dorsal pontine tegmentum including LC-alpha and peri-LC-alpha in the intact cat induced high amount of REM sleep with short latency of less than 5 min, similar microinjection in the cat where brainstem was transected between the pons and the medulla, failed to induce REM sleep with short latency (150).
The Japanese rice fish, medaka (Oryzias latipes), was used as the experimental model in which individual eggs were exposed via microinjection to various known concentrations of PbTx-3 dissolved in an oil vehicle.
In the present study, we have demonstrated that microinjections of leptin into the ARCN or PVN induce increases in RSNA, MAP, and HR.
As one of the experiments required two microinjections, animals designated to be used in this experiment were implanted with a second cannula (0.6 mm o.d.
