Practical HIV diagnostics are urgently needed in resource-limited settings. While HIV infection can be diagnosed using simple, rapid, lateral flow immunoassays, HIV disease staging and treatment monitoring require accurate counting of a particular white blood cell subset, the CD4(+) T lymphocyte. To address the limitations of current expensive, technically demanding and/or time-consuming approa...

Investigating the effect of low-dose radiation exposure on cells using assays of colony-forming ability requires large cell samples to maintain statistical accuracy. Manually counting the resulting colonies is a laborious task in which consistent objectivity is hard to achieve. This is true especially with some mammalian cell lines which form poorly defined or 'fuzzy' colonies, typified by glio...

We studied the effects of yeast in peripheral blood samples on results reported by an ADVIA 120/2120 Hematology System (Bayer HealthCare, Diagnostics Division, Tarrytown, NY). In a simulated candidemia model, very high concentrations (1-5 x 10(8) colony-forming units [CFU]/mL) of Candida glabrata and Candida parapsilosis caused a spuriously elevated platelet count. No such effect was observed w...

In this paper we present an alternative approach to the problem of spot counting in interphase cell nuclei. Spot counting is a technique to detect defects of chromosomes in cells. By counting the number of spots which are labeled (read coloured) chromosomes one is able to indicate whether this cell has abberation that indicates a serious illness. We will not focus on the staining techniques use...

This paper describes the study of overlapping leukaemia cells based on geometric features for identification and classification. Geometric blood are proposed to identify classify into groups different degrees number overlapped cells. In method, percentage average accuracy identifying reached 98 percent. The method can segment white from with an degree 70 Improved Watershed Algorithm successfull...

By TAPIO RYTOMAA P HLOXINE in propylene glycol provides a good and simple method of staining for the counting of eosinophilic granulocytes in the counting chamber. No comparable method has been available for the counting of neutrophils. The identification of cell types in certain excreta of the organism, especially in the intestinal contents, is a cumbersome procedure.”2 It has, however, proved...

Objective(s)Progesterone is a steroid hormone whose biology has been greatly studied within the confines of reproductive function. In recent years, the neuroprotective effects of progesterone have attracted growing interest. Glial cell line-derived neurotrophic factor (GDNF), is a neurotrophic factor which plays a crucial role in the development and maintenance of distinct sets of central and p...

This paper presents a novel cell counting system which exploits the Fast Radial Symmetry Transformation (FRST) algorithm [1]. The driving force behind our system is a research on neurogenesis in the intact nervous system of Manduca Sexta or the Tobacco Hornworm, which was being studied to assess the impact of age, food and environment on neurogenesis. The varying thickness of the intact nervous...

Formocresol is common treatment in exposed pulp of primary teeth at caries, trauma and damaged with cavity preparation. Although, clinical and radiographic success and good clinical results are observed, dentistry societies are still searching for materials interchangeable with formocresol. Suab1 is a phytochemical agent that was selected because of its anti- bleeding effect. In this study, we ...
