A model is presented to calculate the light-scatter properties of nucleated blood cells which are mimicked by two concentric spheres. The light-scatter characteristics were derived from the Rayleigh-Debye-Gans approximation and by simultaneous application of field averaging of the internal field and modification of the propagation constant inside the different cellular compartments. It is shown...
Mice were generated expressing green fluorescent protein (GFP) under the control of the gonadotropin-releasing hormone (GnRH) promoter. Green fluorescence was observed in, and restricted to, GnRH-immunopositive neuronal somata in the olfactory bulb, ganglion terminale, septal nuclei, diagonal band of Broca (DBB), preoptic area (POA), and caudal hypothalamus, as well as GnRH neuronal dendrites a...
Microtubules are implicated in the movement and positioning of nuclei in many cell types. Nuclei can be moved by forces acting on microtubules nucleated at the spindle pole body, as in fungi [1], or microtubules nucleated at the centrosome, as during migration of the male (sperm) pronucleus towards the centre of the zygote after fertilization [2] [3] [4]. The dramatic movements of the female pr...
The plasma membrane of the nucleated pigeon erythrocyte was isolated by a method that is simple, reproducible and minimally disruptive, the final preparation consisting of whole cell 'ghosts', recovered at over 40% yield. Alternative methods, which yield membrane fragments, were also tested and some of their possible disadvantages demonstrated. Analysis of the protein components of the isolated...
BACKGROUND Human induced pluripotent stem cells offer perspectives for cell therapy and research models for diseases. We applied this approach to the normal and pathological erythroid differentiation model by establishing induced pluripotent stem cells from normal and homozygous sickle cell disease donors. DESIGN AND METHODS We addressed the question as to whether these cells can reach comple...
introduction: bleomycin sulfate is a dna damaging agent used in cancer chemotherapy. the effect of this drug on various cell cycle stages might be different, thus inducing different modes of death (apoptotic or mitotic death). the aim of this investigation was to study the effects of bleomycin on human peripheral blood lymphocytes at various cell cycle stages by two different end points (induct...
We found a group of non-platelet RNA-containing particles (NPRCP) in human umbilical cord blood. To understand the origin, characterization and differentiation of NPRCP, we examined cord blood-isolated NPRCP in vitro. The NPRCP range in size from < 1 to 5 μm, have a thin bilayer membrane and various morphological features, contain short RNA and microRNA and express octamer-binding transcription...
PURPOSE To evaluate the clinical and laboratory characteristics of pleural effusions secondary to tuberculosis (TB) or cancer (CA). METHODS A total of 326 patients with pleural effusion due to TB (n=182) or CA (n=144) were studied. The following parameters were analyzed: patient gender, age and pleural effusion characteristics (size, location, macroscopic fluid aspect, protein concentration, ...
