BACKGROUND To current knowledge, different oocyte's recovery method and various seasons have profound impact on in vitro embryo production (IVEP). OBJECTIVES The aim of this study was to define an efficient recovery method for oocytes harvesting from slaughterhouse material in different seasons, and their effects on IVEP yield. MATERIALS AND METHODS Ovaries from slaughtered ewes in breeding...

OBJECTIVE Expanded newborn screening (NBS) identifies some disorders for which clinical benefit is uncertain, as well as "incidental" findings (eg, carrier status), thus enhancing the need to inform parents about NBS before sample collection. METHODS A self-complete survey was sent to a cross-sectional, stratified, random sample of 5 provider groups in Ontario (obstetricians, midwives, family...

BACKGROUND The autosomal recessive chromosomal instability disorder Nijmegen breakage syndrome (NBS) is associated with increased risk of lymphoid malignancies and other cancers. Cells from NBS patients contain many double-stranded DNA breaks. More than 90% of NBS patients are homozygous for a founder mutation, 657del5, in the NBN gene. We investigated the 657del5 carrier status of cancer patie...

Nijmegen breakage syndrome (NBS), a rare autosomal recessive condition also known as ataxia telangiectasia (AT) variants VI and V2, is characterised by microcephaly, typical facies, short stature, immunodeficiency, and chromosomal instability. We report the clinical, immunological, chromosomal, and cell biological findings in 42 patients who are included in the NBS Registry in Nijmegen. The imm...

The ret finger protein (rfp) is a member of the B-box zinc finger gene family many of which may function in growth regulation and in the appropriate context become oncogenic. Members of this family are nuclear proteins that possess a characteristic tripartite motif consisting of the RING and B-box zinc binding domains and a coiled-coil domain. The promyelocytic leukemia gene (PML), another B-bo...

Major human pathologies are caused by nuclear replicative viruses establishing life-long latent infection in their host. During latency the genomes of these viruses are intimately interacting with the cell nucleus environment. A hallmark of herpes simplex virus type 1 (HSV-1) latency establishment is the shutdown of lytic genes expression and the concomitant induction of the latency associated ...

Eucalyptus grandis is a commercially important hardwood species and is known to be susceptible to a number of pests and pathogens. Determining mechanisms of defense is therefore a research priority. The published genome for E. grandis has aided the identification of one important class of resistance (R) genes that incorporate nucleotide binding sites and leucine-rich repeat domains (NBS-LRR). U...

The development of innovative targeted therapeutic approaches are expected to surpass the efficacy of current forms of treatments and cause less damage to healthy cells surrounding the tumor site. Since the first development of targeting agents from hybridoma's, monoclonal antibodies (mAbs) have been employed to inhibit tumor growth and proliferation directly or to deliver effector molecules to...

In this study, we characterized the miR482 family in cotton using existing small RNA datasets and the recently released draft genome sequence of Gossypium raimondii, a diploid cotton species whose progenitor is the putative contributor of the Dt (representing the D genome of tetraploid) genome of the cultivated tetraploid cotton species G. hirsutum and G. barbadense. Of the three ghr-miR482 mem...
