Four experiments examined the role of the nucleus tractus solitarius (NTS) and subjacent nucleus reticularis ventralis (NRV) in the production of antinociception. Experiment 1 showed that microinjection of glutamate (50 nmol) into the caudal NTS resulted in inhibition of the tail-flick reflex, hypotension, and mild bradycardia, whereas microinjection of glutamate into the rostral NTS resulted o...
Gap junctional intercellular communication (GJIC) is a critical part of cellular activities and is necessary for electrical propagation among contacting cells. Disorders of gap junctions are a major cause for cardiac arrhythmias. Dye transfer through microinjection is a conventional technique for measuring GJIC. To overcome the limitations of manual microinjection and perform high-throughput GJ...
The meganuclease I-SceI has been effectively used to facilitate transgenesis in fish eggs for nearly a decade. I-SceI-mediated transgenesis is simply via embryo cytoplasmic microinjection and only involves plasmid vectors containing I-SceI recognition sequences, therefore regarding the transgenesis process and application of resulted transgenic organisms, I-SceI-mediated transgenesis is of mini...
Electron Microscopy: Daniel C. Pease .............. 543 Incorporation of C14 From Carboxyl-labeled dl-Alanine Into the Proteins of Liver Slices: Ivan D. Frantz, Jr., Robert B. Loftfield, and Warren W. Miller ........ ...................... 544 Isolation of Avian Pneumoencephalitis (Newcastle Disease) Virus From the Yolk Sac of Four-Day-Old Chicks, Embryos, and Infertile Eggs: P. D. DeLay 545 An...
The mutant Paramecium tetraurelia cell line d48 is unable to express the serotype A protein on its surface. Although the A gene is intact in the micronuclei of d48, the A gene copies in the macronucleus contain a large deletion eliminating virtually the entire coding sequence. Previous studies showed that microinjection of a plasmid containing the entire A gene into the macronucleus of d48 perm...
BACKGROUND To verify whether or not microinjection of sperm with a normal nuclear shape but large vacuoles affects IVF-ICSI pregnancy outcome. METHODS A comparative study testing IVF outcome parameters of IVF-ICSI, based on morphological selection of spermatozoa with normal nuclei against those based on microinjection of sperm with a normal nuclear shape but large vacuoles. An experimental gr...
Primary or continuous lines of mouse cells (3T3) are nonpermissive for simian virus 40 (SV40). Abortively infected cells synthesize tumor antigen (T antigen but not viral DNA and virus capsid protein (V antigen). V antigen, however, was obtained when SV40 DNA was injected into 3T3 cells. This late gene expression also appears to be correlated with the quantity of injected DNA molecules per 3T3 ...
Brain microinjection can aid elucidation of the molecular substrates of complex behaviors, such as motivation. For this purpose rodents can serve as appropriate models, partly because the response to behaviorally relevant stimuli and the circuitry parsing stimulus-action outcomes is astonishingly similar between humans and rodents. In studying molecular substrates of complex behaviors, the micr...
It is demonstrated that the microinjection of cytoplasm from competent, fully grown oocytes can induce germinal vesicle breakdown in meiotically incompetent growing oocytes. Injection of cytoplasm from oocytes at methaphase I had a similar effect. The maturation in injected growing oocytes was arrested at the premetaphase or metaphase I stage. Induction of germinal vesicle breakdown by cytoplas...
