T HE philosophy of technology is in a state of growth. In the past two years alone, over a dozen philosophical studies of technology have .~. appeared. Occasional references are even made to a new wave m philosophy of technology. Indeed, of the three recent anthologies that will be discussed here, two pretend to present a sampling of 'the new philosophy of technology.' Introducing New Direction...

  Background : Chronic Kidney Disease (CKD) is a complicated kidney problem causing permanent renal failure in progressive stages. The final stage of CKD is called ESRD in which most accepted management is Hemodialysis (HD). Arterio-Venus Fistula (AVF) is the most practical way of making proper access to the blood circulatory system however, maturation of the AVF is a challenge, since there are...

background: in vitro maturation (ivm) of oocytes reduces the costs and averts the side-effects of gonadotropin stimulation for in vitro fertilization (ivf). reliable ivm is an intellectual, scientific and clinical challenge with a number of potential applications. objective: the effect of hcg was evaluated on the timing and regulation of in vitro ovulation for the syrian mice oocytes in the pre...

the aim of the study was to compare the parthenogenetic activation and in vitro fertilization (ivf) of in vitro matured caprine oocytes. a total of 881 cumulus-oocyte complexes (coc’s) were collected from 243 ovaries. oocytes were matured in tcm-199 medium containing ecg (20 iu/ml), hcg (20 iuμg/ml), oestradiol-17β (1 μg/ml), bsa embryo tested (3 mg/ml) supplemented with 10% fetal bovine serum ...

background: therapeutic potential of in vitro maturation (ivm) in infertility is growing with great promise. although significant progress is obtained in recent years, existing ivm protocols are far from favorable results. the first aim of this study was to investigate whether two step ivm manner change reactive oxygen species (ros) and total antioxidant capacity (tac) levels. the second aim wa...

Background: Heat shock may affect different aspects of oocyte maturation and its subsequent development to the blastocyst stage. A series of in vitro experiments was performed to determine whether physiologically heat shock (41°C) disrupts the progression of the ovine oocytes through meiosis, activation and blastocyst formation. Materials and Methods: The cumulus-oocyte complexes (COCs) were as...
