INTRODUCTION For many donor-conceiving heterosexual parents, the process of deciding whether and what to tell children about their genetic origin is challenging. We hypothesized that incomplete couple agreement about disclosure could be associated with parenting stress. The aim of the study was to investigate: (1) parenting stress levels among heterosexual parents of young children following ga...
purpose: this study evaluated the effect of donor and eye bank characteristics on graft rating and clinical outcomes after penetrating keratoplasty (pk) in keratoconus-affected patients. methods: a total of 252 consecutive keratoconic eyes that underwent pk were reviewed in this retrospective interventional case series. donor data included age and sex, cause of death, death-to-preservation time...
from 1986 to 1996, 1020 renal transplants were performed at our center. the purposes of this study were. 1) to evaluate the patient and graft survival rates and 2) to see if some donors and recipient characteristics such as age, sex and relationship had any effects on graft survivals. 571 transplants were from living related donors (lrd) and 446 from living unrelated donors (lud). 65.9% of reci...
the most important factor in donor-recipient matching for hematopoietic stem cell transplantation is their hla typing. for many patients, we can not find a full-matched donor. in high risk patients, one locus mismatched related donors are suitable alternatives. (1, 2) since the matching of patients and their siblings usually is based on low resolution hla typing, the matching of one locus mism...
copolymerization of ethylene and propylene was investigated using a 4th generation phthalate ziegler-natta catalyst in normal hexane in a buchi reactor. the effects of different mole fractions of [al]/[ti], [si]/[al] and various amounts of hydrogen on productivity and weight percent of ethylene on the product, were studied. in the copolymerization reactions, tri-isobutyl aluminum (tibal) was us...
We experimentally studied the performance of a delay-line interferometer-based optical signal-to-noise ratio (OSNR) monitor that is pre-calibrated in optimal conditions for 25-Gbaud pol-muxed quadrature-amplitude-modulation (QAM) signals, when unpredicted changes outside the monitor occurred either in the transmitter or the link.
BACKGROUND This study investigates the new phenomenon of parents of donor offspring searching for and contacting their child's 'donor siblings' (i.e. donor offspring conceived by the same donor) and donor. METHODS Online questionnaires were completed by 791 parents (39% lone-mother, 35% lesbian-couple, 21% heterosexual-couple, 5% non-specified) recruited via the Donor Sibling Registry; a US-b...
Blood donor screening for HIV antibody was carried out at Blood Transfusion Service of Jinnah Postgraduate Medical Centre. Sera of 1655 blood donors were tested by Enzyme linked Immuno-Sorbent Assay (Abbott recombinant HIV-1-EIA) from March, 1987 to December, 1989. Initial reactivity was noted in seven cases, of which three were repeatedly reactive. When these were tested by western blot at Nat...
Donor selection for allografting of a non-paired vital organ, such as the heart, is necessarily limited to cadaveric or possibly xenogeneic sources. In contrast, because of the presence in most normal persons of two kidneys – each with a physiological reserve capable of providing four times the minimal required function – renal transplantation has become an accepted medical procedure using cada...
