Vacuum venting is a method proposed to improve feature replication in microparts that are fabricated using micro-injection molding (MIM). A qualitative and quantitative study has been carried out to investigate the effect of vacuum venting on the nano/microfeature replication in MIM. Anodized aluminum oxide (AAO) containing nanofeatures and a bulk metallic glass (BMG) tool mold containing microfeatures were used as mold inserts. The effect of vacuum pressure at constant vacuum time, and of vacuum time at constant vacuum pressure on the replication of these features is investigated. It is found that vacuum venting qualitatively enhances the nanoscale feature definition as well as increases the area of feature replication. In the quantitative study, higher aspect ratio (AR) features can be replicated more effectively using vacuum venting. Increasing both vacuum pressure and vacuum time are found to improve the depth of replication, with the vacuum pressure having more influence. Feature ...

Circumscribed lesions were made within either the corticospinal tract or the ascending dorsal column tracts at the upper cervical level in adult rats. The responses of the tract axons were studied by orthograde transport from injections of horseradish peroxidase or biocytin. At 2 d, the ends of the cut axons were swollen, and the lesions induced en passant varicosities in the adjacent uncut axons. Although there have been reports of retraction, we found that even after several weeks, large numbers of cut axons still persisted in the central lesion area (where there was complete tissue destruction and intense macrophage infiltration), and also in the adjacent regions of the tract. The cut ends were expanded into a variety of shapes--large, complex, bulbous, and recurved--and many had profuse local branches with or without small, terminal-type varicosities. A suspension of Schwann cells cultured from neonatal sciatic nerve was injected by a minimally traumatic air pressure microinjection technique ...

In order to elucidate gene function and regulation, transgenic mouse models have become indispensable to genetic research. In particular, Gene Targeting, utilizing Homologous Recombination (HR) in cultured pluripotent embryonic stem (ES) cells, has become an integral tool to study specific gene function and regulation. However, highly sophisticated microinjection techniques are also still crucial methods for generating transgenic animal models. To overcome the current technical and biological limitations in gene targeting, two innovative approaches were developed in this work. One approach deals with targeted clone identification in gene targeting experiments by visualizing targeting events utilizing the presence of fluorescence genes. Therefore, we derived a double fluorescent ES cell line from the Cre reporter Gt(ROSA)26Sortm4(ACTB-tdTomato,-EGFP)Luo/J strain which expresses membrane-targeted tdTomato (mT) and upon Cre recombination, membrane-targeted EGFP (mG) on the Rosa26 locus. Animals ...

Transgenic rats have been used as model animals for human diseases and organ transplantation and as animal bioreactors for protein production. In general, transgenic rats are produced by pronuclear microinjection of exogenous DNA. Improvement of post-injection survival has been achieved by micro-vibration of the injection pipette. The promoter region, structural gene, chain length and strand ends of the exogenous DNA are not involved in the production efficiency of transgenic rats. Exogenous DNA prepared at 5 μg/ml seemed to be better integrated than lower and higher concentrations. Intracytoplasmic sperm injection (ICSI) has been successfully achieved in rats using a piezo-driven injection pipette. The ICSI technique has not only been applied to rescue infertile male strains but also to produce transgenic rats. The optimal DNA concentration for the ICSI-tg method (0.1 to 0.5 μg/ml) is lower than that for the conventional pronuclear microinjection. Production efficiency was improved when the ...

The bed nucleus of stria terminalis (BNST) is a limbic forebrain structure involved in hypothalamo-pituitary-adrenal axis regulation and stress adaptation. Inappropriate adaptation to stress is thought to compromise the organisms coping mechanisms, which have been implicated in the neurobiology of depression. However, the studies aimed at investigating BNST involvement in depression pathophysiology have yielded contradictory results. Therefore, the objective of the present study was to investigate the effects of temporary acute inactivation of synaptic transmission in the BNST by local microinjection of cobalt chloride (CoCl2) in rats subjected to the forced swimming test (FST). Rats implanted with cannulae aimed at the BNST were submitted to 15 min of forced swimming (pretest). Twenty-four hours later immobility time was registered in a new 5 min forced swimming session (test). Independent groups of rats received bilateral microinjections of CoCl2 (1 mM/100 nL) before or immediately after pretest or

Microinjection of DNA. Injection of linear DNA molecules into fertilized eggs (pronuclear stage) using an inverted microscope, micromanipulation equipment and injection / holding devices.. The first successful production of transgenic mice using pronuclear microinjection was reported in 1980 [1]. The pronuclear microinjection method of producing a transgenic animal results in the introduction of linear DNA sequences into the chromosomes of the fertilized eggs. If this transferred genetic material is integrated into one of the embryonic chromosomes, the animal will be born with a copy of this new information in every cell. The foreign DNA must be integrated into the genome prior to the doubling of the genetic material that precedes the first cleavage.. If this does not occur, only a few cells will integrate the gene. For this reason, the DNA is introduced into the fertilized egg at the earliest stage, which is the pronuclear period immediately following fertilization. For several hours following ...

Zebrafish paraxial protocadherin (papc) encodes a transmembrane cell adhesion molecule (PAPC) expressed in trunk mesoderm undergoing morphogenesis. Microinjection studies with a dominant-negative secreted construct suggest that papc is required for proper dorsal convergence movement s during gastrulation. Genetic studies show that papc is a close downstream target of spadetail, gene encoding a transcription factor required for mesodermal morphogenetic movements. Further, we show that the floating head homeobox gene is required in axial mesoderm to repress the expression of both spadetail and papc, promoting notochord and blocking differentiation of paraxial mesoderm. The PAPC structural cell-surface transcription factors and the actual cell biological behaviors that execute morphogenesis during gastrulation ...

A recent report compared the efficiency of microinjection of DNA versus RNA in mouse embryos [1]. While it was shown that DNA is effective, in vitro transcribed RNA was observed to be more efficient.. Typically, microinjections for CRISPR applications are performed using in vitro transcribed Cas9 and sgRNA rather than native dsDNA. gBlocks® Gene Fragments are ideal for use as template for in vitro transcription and will work well in these applications [2,3]. However, long RNAs are known to trigger the innate immune response in many cells, which increases the expression of dozens of genes and can affect cell viability and general health [4-7]..

The aim of this study was to investigate the expression of prostaglandin EP1 receptor within the ventrolateral periaqueductal grey (VL PAG). The role of VL PAG EP1 receptor in controlling thermonociception and rostral ventromedial medulla (RVM) activity in healthy and neuropathic rats was also examined. EP1 receptor was indeed found to be expressed within the VL PAG and co-localized with vesicular GABA transporter. Intra-VL PAG microinjection of ONO-DI-004, a selective EP1 receptor agonist, dose-dependently reduced tail flick latency as well as respectively increasing and decreasing the spontaneous activity of ON and OFF cells. Furthermore, it increased the ON cell burst and OFF cell pause. Intra-VL PAG prostaglandin E2 (PGE2) behaved similarly to ONO-DI-004. The effects of ONO-DI-004 and PGE2 were antagonized by intra-VL PAG L335677, a selective EP1 receptor antagonist. L335677 dose-dependently increased the tail flick latency and ongoing activity of the OFF cells, while reducing the ongoing ON cell

The pig has emerged as an important large animal model in biomedical and pharmaceutical research. We describe a protocol for high-efficiency germline transgenesis and sustained transgene expression in pigs by using the Sleeping Beauty (SB) transposon system. The protocol is based on co-injection of a plasmid encoding the SB100X hyperactive transposase, together with a second plasmid carrying a transgene flanked by binding sites for the transposase, into the cytoplasm of porcine zygotes. The transposase mediates excision of the transgene cassette from the plasmid vector and its permanent insertion into the genome to produce stable transgenic animals. This method compares favorably in terms of both efficiency and reliable transgene expression to classic pronuclear microinjection or somatic cell nuclear transfer (SCNT), and it offers comparable efficacies to lentiviral approaches, without limitations on vector design, issues of transgene silencing and the toxicity and biosafety concerns of working ...

Dysfunction of the apelinergic system, comprised of the neuropeptide apelin mediating its effects via the G protein-coupled apelin receptor (APJ), may underlie the onset of cardiovascular disease such as hypertension. Apelin expression is increased in the rostral ventrolateral medulla (RVLM) in spontaneously hypertensive rats (SHRs) compared to Wistar-Kyoto (WKY) normotensive rats, however, evidence that the apelinergic system chronically influences mean arterial blood pressure (MABP) under pathophysiological conditions remains to be established. In this study we investigated, in conscious unrestrained rats, whether APJ contributes to MABP and sympathetic vasomotor tone in the progression of two models of hypertension - SHR and L-NAME-treated rats - and whether APJ contributes to the development of hypertension in pre-hypertensive SHR. In SHR we showed that APJ gene (aplnr) expression was elevated in the RVLM, and there was a greater MABP increase following microinjection of [Pyr1]apelin-13 to the RVLM

Bilateral microinjection into the RVLM of an adenovirus, which expresses a constitutively active version of the AT1A receptor in glial cells, increases MAP in conscious, freely moving rats of a normotensive strain. Expression of similar levels of the wild-type AT1A receptor, or the control adenovirus with no receptor transgene, did not affect blood pressure. Although not directly measured in this study, we suggest that the increase in blood pressure following microinjection of AdNHA[N111G]AT1A into the RVLM would be caused by increased sympathetic vasomotor tone.. Virally-derived proteins, including specifically the ectopic expression of the AT1A receptors, were only detectable in glia of the RVLM, indicating that a change in activity of a G protein-coupled receptor in glia has the capacity to alter blood pressure. Glia were initially considered to play only a supporting role within the CNS, but recent work has demonstrated that considerable interactions occur between glia and neurons, resulting ...

Acute hypertension produced by methamphetamine (MA) is well known, mainly by the enhancement of catecholamine release from sympathetic terminals. However, the central pressor mechanism of the blood-brain-barrier-penetrating molecule remains unclear. We used radio-telemetry and femoral artery cannulation to monitor the mean arterial pressure (MAP) in conscious free-moving and urethane-anesthetized rats, respectively. Expression of Fos protein (Fos) and phosphorylation of N-methyl-D-aspartate receptor subunit GluN1 in the rostral ventrolateral medulla (RVLM) were detected using Western blot analysis. ELISA was carried out for detection of protein kinase C (PKC) activity in the RVLM. MA-induced glutamate release in the RVLM was assayed using in vivo microdialysis and HPLC. Systemic or intracerebroventricular (i.c.v.) administration of MA augments the MAP and increases Fos expression, PKC activity, and phosphorylated GluN1-ser 896 (pGluN1-ser 896) in the RVLM. However, direct microinjection of MA into the

Transgenic techniques have rapidly evolved in recent years. However, the efficiency of these techniques to produce viable offspring is still disappointingly low. The purpose of this study was to assess in vitro development, transgene expression, and integration following pronuclear or cytoplasmic microinjection of condensed or linear green fluorescent protein DNA into murine embryos using electroporation. In experiment 1, the effect of embryo orientation (group or linear) within the electroporation chamber on development was evaluated using zygotes which received one pulse duration (10 msec), and one of two voltages (250 or 400 V). Zygotes that received 400 V had the lowest development score (Group, 2.06 ? 0.12; Linear, 1.97 ? 0.13), irrespective of orientation. Embryos that received 250 V had the highest development of the voltage treated groups (Group 3.42 ? 0.12; Linear 3.32 ? 0.12), irrespective of orientation, and development was lower than the control embryos (Control 4.28 ? 0.12; Mannitol ...

In the mouse, the nucleotides three bases downstream of the two response elements are guanine and cytosine, suggesting that dioxin cannot activate Bax. Indeed, mouse oocytes are normally insensitive to dioxin, and oocyte microinjection experiments with a construct containing the wildtype Bax promoter confirm that dioxin is ineffective at induction. Furthermore, mutation of these critical downstream nucleotides to adenine renders the promoter responsive to dioxin. Thus, two nucleotides in the Bax promoter would seem to be the sole protection against damage mediated by dioxin.Matikainen et al.6 further show the effects of the PAH 9,10-dimethylbenz(a)antracene (DMBA) on oocytes and on Bax levels (see figure). Intraperitoneal delivery of DMBA causes a 72% increase in Bax mRNA levels after 24 hours, and a concomitant increase in Bax protein in oocytes. Treatment with DMBA or a DMBA metabolite also leads to a decrease in the number of non-apoptotic oocytes in cultured wildtype mouse ovaries. ...

The present study investigated the neuronal and cardiovascular responses elicited by adenosine microinjected into the pressor (rostral) and depressor (caudal) areas of the NTS of SHR and WKY. In addition to confirming reported cardiovascular7 8 9 10 11 15 and neuronal11 responses observed in normotensive rats, results of the current study demonstrate for the first time the neuronal and cardiovascular responses elicited by adenosine microinjected into the two subareas of the NTS in SHR.. Microinjection of adenosine into the NTS elicited site-dependent cardiovascular responses. Increases and decreases in BP and HR followed microinjection of adenosine into the rostral and caudal NTS, respectively. Nonetheless, adenosine inhibited the firing rate of both neuronal pools. These findings in WKY confirm and extend our previous findings in another strain of normotensive rats, the Sprague-Dawley rat.11 Results from the present study and our previous study11 showed that the neuronal responses preceded the ...

One aspect of research in our laboratory is directed toward a detailed understanding of the molecular mechanisms by which vertebrate organisms develop from single-celled embryos into complex organisms. This research utilizes zebrafish as a model organism. Advantages of the zebrafish include fecundity, an optically clear, rapidly developing embryo, and the opportunity to experimentally manipulate fertilization and development so as to produce parthenogenetic or haploid offspring. In addition, a full genomic sequence is available. A technique of central importance is the production of transgenic zebrafish via the direct microinjection of cloned genes into fish embryos. Transgenic zebrafish possessing recombinant gfp and rfp marker genes are being generated for a variety of purposes, including 1) basic research into recombination mechanisms and transgenesis strategies, 2) the study of transgene inheritance patterns, and 3) the analysis of altered gene expression and its phenotypic ...

ICSI is the most successful form of treatment for men who are infertile & is used in nearly half of all IVF treatments. ICSI only requires one sperm.

Prior to the development of molecular genetics, the only way of studying the regulation and function of mammalian genes was through the observation of inherited characteristics or spontaneous mutations. Long before Mendel and any molecular genetic knowledge, selective breeding was a common practice among farmers for the enhancement of chosen traits, e.g., increased milk production.. During the 1970s, the first chimeric mice were produced (Brinster, 1974). The cells of two different embryos of different strains were combined together at an early stage of development (eight cells) to form a single embryo that subsequently developed into a chimeric adult, exhibiting characteristics of each strain.. The mutual contributions of developmental biology and genetic engineering permitted rapid development of the techniques for the creation of transgenic animals. DNA microinjection, the first technique to prove successful in mammals, was first applied to mice (Gordon and Ruddle, 1981) and then to various ...

As some of you know, weve just had our second failed ICSI (intracytoplasmic sperm injection) cycle. Were not sure whether to go for a third at all, but one of the things Im considering is whether we should change clinics if we do. I like our current clinic. Its very personal (only 2 consultants and near enough always see the same one), everyone is very friendly, and its local and easy to get to. They havent done anything wrong per se, but our last cycle was a bit of a mess with poor response, 100% immature eggs and only one fertilising. We have follow up soon, and Ive no doubt they will change things, but is that enough? I wonder whether a completely fresh approach may be better. My criticisms of our clinic are that they seem to treat everyone in a very similar fashion (almost everyone is on SP, for example) and the monitoring in terms of scans and blood tests seems no where near as tight as Ive read about at other clinics. Has anyone here changed clinics? If so, why? What did you look

The ubiquitous, freshwater microcrustacean Daphnia pulex provides a model system for both human health research and monitoring ecosystem integrity. It is the first crustacean to have a well annotated, reference genome assembly that revealed an unusually high gene count highlighted by a large gene orphanage,-i.e., previously uncharacterized genes. Daphnia are capable of either clonal or sexual reproduction, making them ideally suited for genetic manipulation, but the establishment of gene manipulation techniques is needed to accurately define gene functions. Although previous investigations developed an RNA interference (RNAi) system for one congener D. magna, these methods are not appropriate for D. pulex because of the smaller size of their early embryos. In these studies, we develop RNAi techniques for D. pulex by first determining the optimum culture conditions of their isolated embryos and then applying these conditions to the development of microinjection techniques and proof-of-principle RNAi

Recently, the Kim Lab has shown that the cystic fibrosis transmembrane conductance regulator (cftr) gene is responsible for mediating resistance to Pseudomonas aeruginosa in a zebrafish infection model. Using the Gene Expression Omnibus, an NCBI functional genomics data repository, it was determined that Smad3, a transcription factor in the TGF-β signaling pathway, is upregulated in the presence of P. aeruginosa. It was found that in our zebrafish model, the Smad3 paralogs Smad3a and Smad3b are upregulated following microinjection of a cftr antisense morpholino oligomer. It was also found that microinjection of Smad3a and Smad3b morpholinos, along with a Smad2 morpholino, and subsequent infection with Pseudomonas aeruginosa resulted in an increase in death, indicating that Smad3 has a protective effect against infection.

This approach effectively reduces the size of the cDNA library to be screened and increases the probability of successful isolation of the target cDNA. The vocal apparatus of the clawed frog is designed for underwater sound production (Deuchar, 1975).

Peptide nucleic acids (PNAs) are polyamide oligomers that can strand invade duplex DNA, causing displacement of one DNA strand and formation of a D-loop. Binding of either a T10 PNA or a mixed sequence 15-mer PNA to the transcribed strand of a G-free transcription cassette caused 90 to 100 percent site-specific termination of pol II transcription elongation. When a T10 PNA was bound on the nontranscribed strand, site-specific inhibition never exceeded 50 percent. Binding of PNAs to RNA resulted in site-specific termination of both reverse transcription and in vitro translation, precisely at the position of the PNA.RNA heteroduplex. Nuclear microinjection of cells constitutively expressing SV40 large T antigen (T Ag) with either a 15-mer or 20-mer PNA targeted to the T Ag messenger RNA suppressed T Ag expression. This effect was specific in that there was no reduction in beta-galactosidase expression from a coinjected expression vector and no inhibition of T Ag expression after microinjection of ...
