Immunological role of the placenta, blocking factors and NK cells in post-implantation pregnancy
(2001)
The unexpected failure of the mother to immunologically reject the foetus is partly thought to result from immunological properties of the placenta. The placental trophoblast produces immunosuppressive factors including ...
Immunoglobulin G bound to ovine placenta is eluted by surgical cannulation and acid perfusion in situ
(2005)
OBJECTIVE:
To elute placental bound immunoglobulin G (IgG) in situ.
DESIGN:
Laboratory based experimentation.
SETTING:
Biological Sciences Department, The University of Newcastle Australia and the Department of ...
Human placental immunoglobulins show unique re-association patterns with isologous and third party acid treated trophoblast microvesicles in vitro
(2005)
To study re-association pattern of human placental eluate immunoglobulins with acid treated isologous and third party trophoblast derived placental microvesicles.
DESIGN:
Laboratory based experimentation.
SETTING:
Biological ...
Cellular and molecular interactions in HIV infections: a review
(University of Nairobi, 2002)
To review the cellular and molecular interactions between HIV and the host immune system that lead to full-blown AIDS.
DATA SOURCES:
Published reports on HIV/host interaction during a fifteen year period beginning from ...
Ovine placental eluate immunoglobulins recognise isologous and third party acid-treated trophoblast microvesicle antigens in vitro
(2006)
Placental microvesicles were prepared from ovine placentae and immunoglobulins eluted with 0.5 M glycine buffer pH 2.5. The ability of eluate immunoglobulins to re-associate with isologous (self) and third party acidified ...
Purification and characterization of an anticoagulant from the salivary glands of the ixodid tick Rhipicephalus appendiculatus
(1991)
An anticoagulant isolated from salivary gland extracts of the ixodid tick Rhipicephalus appendiculatus was purified by gel filtration on Sephadex G-100, ion exchange on DEAE-cellulose, aprotinin-Sepharose, and by ...
Ovine and Human Placental IgG inhibit Human Natural Killer Cell Cytotoxicity in vitro.
(University Of Nairobi, 2001)
To determine the effect of ovine and human placental IgG on human Natural Killer (NK) cell cytotoxicity in vitro placental IgG was eluted at acidic pH and purified by ion exchange and subsequently by affinity chromatography ...
Possible immunological basis for recurrent spontaneous abortions: a review.
(2001)
In normal pregnancy, the pregnant mother paradoxically tolerates the semi-allogeneic foetus until term. Experimental and clinical data to explain such tolerance in man reflects the involvement of multiple mechanisms.
OB ...
Recurrent pregnancy losses and the role of immunotherapy
(2000)
Post implantation pregnancy losses are psychologically and economically stressful to the childbearing population. The etiology in the vast majority of cases is unknown but is partly thought to result from a break-down of ...
Poverty reduction and the HIV / AIDS epidemic in Kenya:What are the core issues
(University of Nairobi, 2000)
The government of Kenya has recently attempted to develop a national budget that gives priority to two pertinent constraints to national development efforts. These are poverty and HIV/AIDS. The poor are those members of ...
