Synaptopodin Expression In Idiopathic Nephrotic Syndrome Of Childhood., Tarak Srivastava, Robert E. Garola, J M. Whiting, Uri S. Alon

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Synaptopodin is a proline-rich protein intimately associated with actin microfilaments present in the podocytes' foot processes. We investigated for synaptopodin expression in children with idiopathic nephrotic syndrome (INS), including minimal change disease (MCD), diffuse mesangial hypercellularity (DMH), and focal segmental glomerulosclerosis (FSGS); in children with congenital nephrotic syndrome of the Finnish type (CNF); and in normal kidney tissue. In particular, we examined whether an association exists between synaptopodin expression in podocyte cells and the response to steroids in INS, and whether synaptopodin expression can predict FSGS upon the initial kidney biopsy in children who progress from MCD or DMH …

Acute Haemolysis In Childhood Falciparum Malaria, H. Ekvall, P. Arese, F. Turrini, K. Ayi, F. Mannu, Zul Premji, A. Bjorkman

Pathology, East Africa

Acute haemolysis associated with clinical episodes of high-level Plasmodium falciparum parasitaemia was studied in 20 children from an holoendemic area (coastal Tanzania). The change in blood haemoglobin (Hb) concentration ranged from -46 to +5 g/L during the 72-h observation period and was linearly related to maximum parasitaemia. Balance studies between loss of blood Hb, increase in plasma Hb and appearance of Hb in the urine indicated that extravascular clearance of red cells was the predominant mode of erythrocyte clearance. Most subjects, however, showed minor signs of intravascular haemolysis. The plasma Hb was ≪1% of blood Hb and haemoglobinuria was detected …

Hemoglobin Concentration In Children In A Malaria Holoendemic Area Is Determined By Cumulated Plasmodium Falciparum Parasite Densities, H. Ekvall, Zul Premji, S. Bennett, A. Bjorkman

Pathology, East Africa

In malaria holoendemic areas children are anemic, but the exact influence of falciparum malaria on hemoglobin (Hb) concentration remains largely unsettled. Prospective data were therefore collected in children < 24 months of age during five months in a Tanzanian village. Children with mean asymptomatic parasitemia ≥ 400/μl had lower median Hb levels during the study than those with mean density < 400/μl. The difference was 9.7 g/L (95% confidence interval [CI] 2.8-17). In children with one or more clinical malaria episodes, the median Hb was 8.3 g/L (95% CI 0.9-16) lower than those without episode. If early treatment failure was recorded, the immediate effect on Hb was particularly important with a mean drop of 17 g/L. Interestingly, at study-end the Hb concentration represented a function of the area under the parasitemia curve (AUPC) during the previous five months, adjusting for age. In conclusion, stepwise deterioration in median Hb levels was found by asymptomatic parasitemia, clinical malaria episode, and most significantly, treatment failure.

Epstein-Barr Virus Serology In The Diagnosis Of Nasopharyngeal Carcinoma From Sarawak, Madeline Wong Mei Fong

Student Works (2000-2009)

The Epstein-Barr virus (EBV) is closely associated with nasopharyngcal carcinoma (NPC). The role(s) of EBV in NPC remains unclear but antibodies to two EBV proteins namely the viral capsid antigen (VCA) and early antigen (EA), are clinically useful diagnostic markers of NPC. The NPC scenario in Malaysia has been based on studies done on West Malaysian patients but not much has been described for NPC in Sarawak, East Malaysia. In this study, 164 NPC sera from newly histologically confirmed NPC patients were collected from the Radiotherapy Unit of Kuching General Hospital, Sarawak prior to radiotherapy. One hundred and forty seven …

Mrnas Encoding Aquaporins Are Present During Murine Preimplantation Development., H Offenberg, L C Barcroft, A Caveney, D Viuff, P D Thomsen, A J Watson

Obstetrics & Gynaecology Publications

The present study was conducted to investigate the mechanisms underlying fluid movement across the trophectoderm during blastocyst formation by determining whether aquaporins (AQPs) are expressed during early mammalian development. AQPs belong to a family of major intrinsic membrane proteins and function as molecular water channels that allow water to flow rapidly across plasma membranes in the direction of osmotic gradients. Ten different AQPs have been identified to date. Murine preimplantation stage embryos were flushed from the oviducts and uteri of superovulated CD1 mice. Reverse transcription-polymerase chain reaction (RT-PCR) methods employing primer sets designed to amplify conserved sequences of AQPs (1-9) …

Attachment Of Toxoplasma Gondii To A Specific Membrane Fraction Of Cho Cells, Chaitali Dutta, Jane Grimwood, Lloyd H. Kasper

Dartmouth Scholarship

We have observed previously that attachment of Toxoplasma gondii to synchronized host cells is considerably increased at the mid-S phase (4 h postrelease). Synchronized CHO host cells at the mid-S phase were fractionated by molecular weight, and the antigens were used to produce a panel of polyclonal mouse antisera. The polyclonal antisera raised against fraction 4 with molecular mass ranging approximately from 18 to 40 kDa significantly reduced attachment to mid-S-phase host cells. Immunofluorescence assays demonstrated strong reactivity to mid-S-phase host cells and identified a number of potential receptors on Western blots. These data indicate that there is a specific …

Studies On The Purification And Role Of Igfbp-5 Protease In Bone, H. Garrett Rush Thompson

Loma Linda University Electronic Theses, Dissertations & Projects

Osteoporosis is a disease characterized by low bone density and deterioration of mineralized bone leading to enhanced susceptibility to fracture. Several growth factors have been implicated in the coupling of formation to resorption during the bone remodeling process. The net bone forming activity of many growth factors has prompted numerous studies focused on the regulation of osteoblast cell proliferation, differentiation and activity. The current study focuses on the insulin-like growth factor (IGF) system, an important growth factor system involved in the regulation of bone formation and bone resorption.
