Zeta sedimentation ratio (ZSR) is a simple, rapid and reproducible test which is not influenced by variables like sex and anemia. There is good correlation with Westergren erythrocyte sedimentation ratio (ESR) in normal and hospital population. Limitation of packing force affects the use of the procedure in polycythemia and in patients with ZSR greater than 80%.

Colloidal mesoporous silica nanoparticles less than 20 nm in diameter are prepared by dialysis; this simple surfactant removal route can avoid aggregation by sedimentation-redispersion and remove cationic surfactants while retaining the original colloidal state, which is applicable to the preparation of primary nanoparticles carrying a functional organic substance.

The Westergren method for the determination of the erythrocyte sedimentation rate has been conclusively shown to be more reliable than other methods (Gilmour and Sykes, 1951 ; Goldberg, Glynn, and Bywaters, 1952; Lewi and Clarke, 1954; Alexander and Andrews, 1957; Eastham, Denson, and Evans, 1958). Blood for a variety of haematological and biochemical investigations is commonly collected into W...

Presence of salts in water has been one of the biggest problems of industrial equipment such as evaporators, boilers, and pipes. These salts gradually form scales on evaporators and boilers tubes and reduce their efficiency. Pretreatment processes are conducted to remove these salts; with sedimentation tanks being one of the essential equipment used in these processes. This study numerically si...

The studies described compare the subpopulations of granulocyte-macrophage progenitor cells present in normal marrow with those derived from the marrow of patients with Ph1-positive chronic myelogenous leukemia (CML). The subpopulations were separated on the basis of size by velocity sedimentation and measured for their proliferative capacity by the colony formation technique. A pattern of deve...

OBJECTIVE To report on a 30-year prospective study of deep infection in 1993 consecutive total hip arthroplasties performed by a single surgeon. METHODS The relations of numerous variables to the incidence of deep infection were studied. RESULTS The cumulative infection rate after the index total hip arthroplasties rose from 0.8% at 2 years to 1.4% at 20 years; 9.6% of the index operations ...

Introduction: Bioassay is necessary for assessment of pollution. Because physical and chemical taste are not enough for assessment of potential effects on water ecosystem. Bioassay tests have alot of scientific value inanition doing of them is easy and need less time, also need less space, laboratory equipment’s and expenditure. Therefor such tests have found special attention in water pollutio...

INTRODUCTION Delirium is a condition with a high prevalence in hospitalised patients (10%-30%), and it has important prognostic implications. There are few prospective studies of the incidence of delirium in Spain, and most of these were carried out in surgical wards or intensive care units. Our objective is to calculate the incidence of delirium in a neurological department and describe charac...
