Isolation and characterization of kinetoplast DNA and RNA of Phytomonas davidi.
Kinetoplast DNA networks were isolated from stationary-phase culture forms of Phyromonas davidi. The networks banded in CsCl at a density of 1.699 g/ml and consisted of covalently closed circular molecules. The networks were sensitive to shear forces and exhibited several discrete sedimenting components in neutral and alkaline sucrose. Closed monomeric minicircles were isolated from sonicated n...
متن کاملInhibition of in vitro macrophage digestion capacity by infection with Leishmania donovani (Protozoa: Kinetoplastida).
Promastigotes of Leishmania donovani transformed into amastigotes and survived in cultured macrophages. Promastigotes of Leptomonas costoris, a kinetoplastid parasite of water striders, transformed into amastigotes but did not survive in cultured macrophages. A significant difference in size between the two species of parasitic protozoa allowed development of a bioassay in which the in vitro di...
متن کامل[Cytological findings in scintigraphically nonfunctioning thyroid nodules].
BACKGROUND/AIM The major one among the procedures for evaluating changes in the thyroid nodules is fine needle aspiration biopsy (FNAB). Thyroid scintigraphy is commonly used in diagnostic algorithm of nodules. Less than 5% of examined nodules show to be malignant. Scintigraphically, nodules could be classified as functional and nonfunctional. It is estimated that the risk of malignancy in nonf...
متن کاملPhylogenetic analysis of Trypanosomatina (Protozoa: Kinetoplastida) based on minicircle conserved regions.
Phylogenetic relationships within the suborder Trypanosomatina were inferred from the kinetoplast DNA minicircle conserved region sequences. Trees built using distance-matrix (Neighbor-Joining) and maximum parsimony methods showed that the minicircle conserved regions (CRs) provide a sensitive and specific molecular marker suitable for phylogenetic analyses of subspecies and strains of trypanos...
متن کاملSpectrum of Cytological Findings in Paediatric Non-Thyroidal NeckSwelling – Experience in a Tertiary Care Children Hospital
Background and Objective: Fine needle aspiration cytology (FNAC) is well accepted as a useful diagnostic technique in the management of adult patients with head and neck lumps. But, until recently, very few reports have been obtained regarding the role of FNAC in nonthyroidal neck masses in children. Hence, the objective of our study was to determine the diagnostic value of fine needle aspirati...
