In its simplest term, IVF is simply the uniting of egg and sperm in vitro (in the lab). Subsequently the embryos are transferred into the uterus through the cervix and pregnancy is allowed to begin. IVF was the first of the ART techniques to be developed. The first birth was in 1978 in England. The procedure was pioneered by a Gynecologist and a Ph.D. (Drs. Steptoe and Edwards). Next came GIFT,...

The distribution of conceptions after artificial insemination from a donor was studied in 259 conceptions at an artificial insemination clinic and found to be seasonal. Conception was not influenced by the number of donors or patients attending the clinic, the frequency of inseminations, or medical skill. Conception was more common from early winter until early spring (October to March) with a ...

Somatic cell nuclear transfer (SCNT) is a useful technique for creating pig strains that model human diseases. However, production of numerous cloned disease model pigs by SCNT for large-scale experiments is impractical due to its complexity and inefficiency. In the present study, we aimed to establish an efficient procedure for proliferating the diabetes model pig carrying the mutant human hep...

There is increasing evidence that a behavioral treatment approach might be efficacious in the treatment of the emotional aspects of infertility and may lead to increased conception rates. The first 54 women to complete a behavioral treatment program based on the elicitation of the relaxation response showed statistically significant decreases in anxiety, depression, and fatigue as well as incre...

Since the birth of the first baby as a result of in vitro fertilisation (IVF) in 1978, many clinics around the world have achieved pregnancies and births for their patients by using IVF and gamete intrafallopian transfer procedures. With the storage of excess embryos, multiple laparoscopies can be avoided; this has favoured the development of better cryopreservation techniques. In our clinic 8-...

Human embryos are selected for transfer using morphology at the cleaving and blastocyst stages. Zygote morphology has been related to implantation and pregnancy. The aim of this study was to relate pronuclear morphology to blastocyst development. Zygotes were scored according to distribution and size of nucleoli within each nucleus. Zygotes displaying equality between the nuclei had 49.5% blast...

xtensional flows and magnetic fields induce similar steady alignment responses when applied to iquid crystals LCs , liquid crystal polymers LCPs and nematic rigid rod or platelet uspensions. This observation is explained for LCs by a classical analogy, expressed as a ymmetry, between hydrodynamic and magnetic fields in the Leslie-Ericksen theory de Gennes nd Prost, The Physics of Liquid Crystal...

BACKGROUND/AIMS Evidence on modifiable factors associated with cognitive impairment in Japanese patients is scarce. This study aimed to determine modifiable factors for cognitive impairment in a Japanese hospital-based population. METHODS Subjects of this cross-sectional study were 1,143 patients of Sado General Hospital (Niigata, Japan) registered in the Project in Sado for Total Health (PRO...

www.thelancet.com Vol 381 May 18, 2013 1693 Conventional thinking behind global eff orts to prevent the deaths of mothers and children younger than 5 years starts with the identifi cation of an intervention with a clear biological pathway for reducing morbidity and mortality, such as a drug, vaccine, micronutrient, or health-related behaviour. The effi cacy of this intervention is then tested i...
