A BIOCHEMICAL VIEW OF ANTIOXIDANTS presents research on medicinal plants and organic chemistry and relates to pharmacological applications. This book discusses antioxidants, derived from fruits and vegetables, that play a vital role in maintaining health. It forms a bridge between biology and chemistry of fruits and vegetables by studying the complex nature of antioxidants. The Biochemical View of Antioxidants consists of 45 chapters. The chapters show that food constitutes a source of many biologically active antioxidants important for health and disease prevention. The antioxidant properties of fruits and vegetables have to do with the presence of tissues with natural antioxidant compounds that protect plants from free radical damage caused by oxygen in the environment or exposure to ultraviolet radiation. According to nutritionists, the most valuable source of antioxidants are fresh fruit and vegetables and natural preparations made from them, such as juices, preserves, marmalades, jams and silage.

This book addresses major problem in the management of patients with cancer of the head and neck. The authors have written six chapters of particular importance for head and neck cancer diagnosis, treatment, and rehabilitation. Chapter 1 describes treatment of patients with squamous cell carcinoma of the head. Chapter 2 presents treatment of patients with squamous cell carcinoma of the neck. Biochemical studies of head and neck cancer treatments are presented in Chapter 3. In chapter 4 biochemical studies of head and neck cancer biomarkers are presented. Photodynamic therapy (PDT) exploits light interactions and photosensitizers to induce cytotoxic reactive oxygen species. Photodynamic diagnosis (PDD) uses the phenomenon of photosensitizer emitting fluorescence to distinguish some tumours from normal tissue. PDT offers a therapeutic solution that has been found to be cost-effective compared to palliative major surgery or chemotherapy. However, despite the significant improvement noted in preclinical and clinical trials, PDT is still not considered the standard treatment option for head and neck cancer. Multiple photosensitizers have been studied and tumours have been treated in a variety of head and neck sites over the last 30 years. Photodynamic therapy is a palliative treatment option for head and neck squamous cell carcinoma patients which induces local inflammation and alters tumour cell morphology.

In this book Characterization of Archaeological Materials by the Use of Light the authors tried to demonstrate the high degree of technology used in laser scanning for archaeological sites. The data collection and review were obtained thanks to the conscious, proprietary data processing and individual knowledge of lidar products, by using the developed especially for archaeological analytical tools, visualization methods data and algorithms processing the point cloud, numerical models and their derivatives. The authors form an interdisciplinary team, they are both archaeologists and laser physicists. This book has four chapters titled: Aerial Laser Scanning, Laser in the conservation of archaeological monuments, Laser analysis of the chemical composition of ceramics and Laser applications to study various solid materials. We presents Airborne Laser Scanning (ALS) such as an advanced method of archaeological prospection. Inthe last few years an increasing number of applications of Light Detection and Ranging (LiDAR) data within World archaeology was noticed. At the same time, ALS is an extremely useful method for conservation purposes. On the other hand, carrying out successive measurements allows for monitoring of facilities, sites and landscapes over time. Along with the growing interest in the method and the growing number of its applications in archaeology, it is worth paying attention to the efficiency of using the ALS and LIDAR.

This book provides a current review of the problem of heavy metal removal. Microorganisms and microbial activity in environments of water and soil are presented in Chapter 1. Chapter 2 covers current knowledge about photoactive materials based on porphyrins. This book reports the manner in which plants interact with heavy metals dependent mainly on the type of contamination, species of plant as well as conditions. The book presents biological strategies for the elimination of heavy metals from polluted habitats-phytoextraction, phytostabilization, phytodegradation, phytostimulation, phytovolatilization and phytofiltration. Also included are analytical methods to determine heavy metals in water such as atomic absorption spectrometry, electrochemical methods, colorimetric and chromatographic techniques.
