This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Characterization of turbid materials by determining their inherent optical properties have attracted strong research interest for potentially wide applications in fields such as material analysis and biomedical optics. The response of a homogeneous turbid sample to an optical excitation can be accurately described by absorption coefficient [mu]a, scattering coefficient [mu]s, and anisotropy factor g based on the radiative transfer theory. Existing spectrophotometric methods typically uses integrating spheres to acquire the light signals. These approaches, however, are difficult to be translated into instruments for users without special training. The research goal of this dissertation research project is two-fold: (1) Develop and validate a new spectrophotometric method without integrating sphere to characterize turbidity for optically thick samples by three optical parameters of [mu]a([lambda]), [mu]s([lambda]) and g([lambda]). (2) Demonstrate the applicability of the new spectrophotometric method as a label-free assay of cell suspension samples treated by a chemotherapy drug. An experimental system has been developed to measure signals of diffuse reflectance Rd, diffuse transmittance Td and forward transmittance Tf as functions of wavelength [lambda] between 460 and 1000nm from two types of samples. We have inversely determined the optical parameters of polystyrene microsphere samples by an in-house build individual photon Monte Carlo (iMC) simulation software. Validation of the new method has been achieved by comparing the optical parameters determined from the measured signals to those predicted by the Mie theory. In addition, we have applied the validated method to obtain the optical properties of MCF-7 cell samples treated by an apoptosis inducing drug doxorubicin for three different doses and three post-treatment times. By comparing to apoptosis measurement results of MTT assay and fluorescent flow cytometry, we were able to qualitatively demonstrate the potential applications of the new spectrophotometric method as a label-free assay to detect cellular apoptosis in treated samples.

Book excerpt: Pigment Cell Growth covers the proceedings of the Third Conference on the Biology of Normal and Atypical Pigment Cell Growth. The book focuses on the nature of the pigment cell and its contained melanin. The selection first offers information on the origin of the mammalian pigment cell and its role in the pigmentation of hair and relations between developing melanophores and embryonic tissues in the Mexican axolotl. The book also examines the genetic control of pigmentation in the fowl; relationship of atypical pigment cell growth to gonadal development in hybrid fishes; and estrogen, thyroid hormone, and the differentiation of pigment cells in the brown leghorn. The publication takes a look at dendritic melanoblasts in metastatic squamous cell carcinoma; microscopic analysis of normal melanoblasts, nevus cells, and melanoma cells; and analysis of skin color in living human subjects by spectrophotometric means. The selection is a dependable source of data for readers interested in pigment cell growth.

Download or read book Advanced Water Supply and Wastewater Treatment A Road to Safer Society and Environment written by Petr Hlavinek and published by Springer. This book was released on 2011-01-15 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stable, safe, secure and readily available water supply is one of the key factors in ensuring a good level of the public health and a stable society. Scientific assessments show that about 80 % of diseases and one-third of the total death toll in the developing countries are caused by the low quality of the drinking water. Other countries are also suffering from water shortages and insufficient quality of the drinking water. Many rivers in Europe and in other parts of the world are significantly polluted by insufficiently treated or untreated wastewater discharge. This book is based on the discussions and papers prepared for the NATO Advanced Research Workshop that took place in Lviv, Ukraine, and addressed recent advances in water supply and wastewater treatment as a prerequisite for a safer society and environment. The contributions critically assess the existing knowledge on urban water management and provide an overview of the current water management issues, especially in the countries in transition in Central and Eastern Europe and in the Mediterranean Dialogue countries.
