Cryopreservation of human gonadal tissue and oocytes has brought about new and exciting research in reproductive medicine, as well as new cryopreservation techniques that are dramatically improving post-thaw viability and freezing damage. The work done on gonadal tissues is aimed at improving the quality of life for infertile patients and for prepubertal(More)
Cloning of buffalos (Bubalus bubalis) through nuclear transfer is a potential alternative approach in genetic improvement of buffalos. However, to our knowledge, cloned offspring of buffalos derived from embryonic, fetal, or somatic cells have not yet been reported. Thus, factors affecting the nuclear transfer of buffalo somatic cells were examined, and the(More)
Most engines used for searching information resources via the Internet employ the Boolean Retrieval Model. Two main drawbacks of this model are that users have difficulty to precisely formulate their concept (or, topic) of interest using Boolean logic and the resulting output is not ranked. We propose to address both these problems by employing a(More)
Many intelligent retrieval approaches have been studied to bridge the terminological gap existing between the way in which users specify their information needs and the way in which queries are expressed. One of the approaches, called Rule Based Information Retrieval by Computer (RUBRIC), uses production rules to capture user query concepts (or topics). A(More)
The pulverized coal systems with tube mills are widely used in coal fired power plants. As there are many controlled variables and disturbances in this system, and startup and shutdown of the system is frequent and the dynamic characteristic of the controlled plant is also extraordinary, the automatic control system for this kind of pulverized coal system(More)
It has been reported that buffalo (Bubalus bubalis) embryos reconstructed by somatic cell nucleus transfer (SCNT) can develop to the full term of gestation and result in newborn calves. However, the developmental competence of reconstructed embryos is still low. Recently, it has been reported that treating donor cells or embryos with trichostatin A (TSA)(More)
To determine whether the age of the female patient, oocyte maturation stage, pronuclei, embryonic quality and/or cycle outcome are related to the intensity of the zona pellucida birefringence (ZPB) in oocytes during IVF procedures, a retrospective study was conducted on 214 IVF cycles using a polarisation imaging system. A negative correlation was found(More)
The objective of this study was to explore the feasibility of employing adult fibroblasts as donor cells in interspecies nuclear transfer (NT) between buffaloes and cattle. Buffalo and bovine oocytes matured in vitro for 22 h were enucleated by micromanipulation using the Spindle View system. An ear fibroblast, pretreated with 0.1 microg/mL aphidicolin for(More)
Ectopically, expression of defined factors could reprogram mammalian somatic cells into induced pluripotent stem cells (iPSCs), which initiates a new strategy to obtain pluripotent stem cell lines. Attempts have been made to generate buffalo pluripotent stem cells by culturing primary germ cells or inner cell mass, but the efficiency is extremely low. Here,(More)
Fetal fibroblasts are often used as donor cells for SCNT, but their short lifespan greatly limits this application. To provide stable and long-lifespan cells, buffalo fetal fibroblasts (BFFs) transfected with human telomerase reverse transcriptase (hTERT). The hTERT-transfected BFFs (hTERT-BFFs) were evaluated by qRT-PCR, Western blot, karyotype analysis,(More)
