Microscale technologies have emerged as a powerful tool for studying and manipulating biological systems and miniaturizing experiments. However, the lack of software complementing these techniques has made it difficult to apply them for many high-throughput experiments. This work establishes Arraycount, an approach to automatically count cells in microwell arrays. The procedure consists of fluo...

Background and Aims: Benzopyrones are a group of compounds including coumarins and chromenes. Chromenes have a heterocyclic structure with gamma benzopyran which has anticancer activities. In this investigation we studied the effect of 4 new derivatives of chromene compounds on the human acute lymphoblastic leukemia cell line MOLT4. Materials and Methods: The structure of the new compound was ...

Background: Automatic Cell Counter devises make the CBC differential very easy and delivering the results in few second. However, the problem with this device is facing a flag requires a time-consuming microscopic review of the specimen which causes unacceptable wait times for patient as well as costs for laboratories. In this study, we calculated the validity of WBC d...

We calculate the number of open walks fixed length and algebraic area on a square planar lattice by an extension operator method used for enumeration closed walks. The walk is defined closing with straight line across their endpoints can assume half-integer values in cell units. also derive counting specific lines outline approach dealing fully endpoints.

The Organic Bound Tritium (OBT) amount in the body may induce changes in the evaluation of the internal exposure to tritium, due to its different retention time relative to HTO. OBT measurements for urine are not performed routinely, mainly because of the lengthy work needed in preparation of the samples, when using the standard oxygen combustion method. A simpler and more rapid method based on...

Flow cytometry is a well-established diagnostic tool for cell counting and characterization. It utilizes fluorescence and scattered excitation light simultaneously emitted from cells passing an excitation laser focus to discriminate various cell types and estimate cell size. Here, we apply the principle of spatially modulated emission (SME) to fluorescently stained SUP-B15 cells as a model syst...

Cell-based microfluidic devices have attracted interest for a wide range of applications. While optical cell counting and flow cytometry-type devices have been reported extensively, sensitive and efficient non-optical methods to detect and quantify cells attached over large surface areas within microdevices are generally lacking. We describe an electrical method for counting cells based on the ...
