University of Illinois researchers have developed a way to produce 3-D images of live embryos in cattle that could help determine embryo viability before in vitro fertilization in humans.Infertility c...
Myostatin (MSTN) can negatively regulate the growth and development of skeletal muscle, and natural mutations can cause “double-muscling” trait in animals. In order to block the inhibiting effect of M...
Monochromatic green light-emitting diodes (LED) light stimuli influences the posthatch growth performance of chicks. This study was undertaken with the following objectives: i) to examine whether the ...
To improve the culture system of bovine somatic cell nuclear transfer (SCNT) embryos, we studied the effects of activin A on developmental competence of bovine SCNT embryos during the early developmen...
Transgenic animals play a vital role in basic research, agriculture and pharmaceutical industries. Rabbits have the advantage of other large laboratory species in that they have a short gestation peri...
The aim of this study was to compare two vitrification methods of porcine perihatching blastocysts with regard to the success of transfer of these embryos to the recipients. Expanded, hatching, or hat...
Double fixed-time insemination after ovulation induction is commonly used in pigs to obtain in vivo produced embryos at defined stages of development for downstream biotechnological applications. Howe...
The aim of this study was to evaluate conception rate after sex determination and subsequent freezing of Day 7 (D7) bovine embryos and to compare it with transfer of fresh female embryos. High quality...
The aim of this study was to evaluate the effect of sex determination procedures in Day 7 to Day 8 bovine embryos of various quality. For the purposes of comparison we used high quality (HQ) as well a...
The aim of this study was to compare pregnancy rates after transfer of in vivo produced embryos cryopreserved using open pulled straw (OPS) vitrification (Group V) or conventional freezing method as a...
The present study was designed to compare the efficiency of bovine embryo production for cryopreservation between oocytes collected from donors in the growth phase of follicular development (GPFD) and...
To facilitate the construction of genetically-modified pigs, we produced cloned embryos derived from porcine fibroblasts transfected with a pair of engineered zinc finger nuclease (ZFN) plasmids to cr...
The present study makes an investigation into expression of genes related to cardiac development in chicken, quail and chicken-quail hybrids during the early stage of embryogenesis. Real-time PCR was ...
In this study, we attenuated a Chinese LX4-type nephropathogenic infectious bronchitis virus (IBV) strain, CK/CH/LHLJ/04V, by serial passage in embryonated chicken eggs. Based on sequence analysis of ...
Cedrela odorata is a tropical tree widely appreciated for its wood. Commercial plantations are frequently hampered by the attack of the meliacea borer, Hypsipyla grandella, and the lack of resistant v...
