During treating target sites especially in lung cancer cases, breathing motion may result unintended variations in the dose distribution. Based on image registration, segmentation and pseudo-color algorithm, the work conducts a study on the calculation and visualization of the heavy dose distribution for 3D superimposed conformal irradiation and dose evaluation. Then the paper investigates the respiratory motion effects on the dosimetric redistribution on target and critical tissues during heavy ion radiotherapy. In our experiments, ten patients have been undergone routine free breathing CT scan, two additional CT scans at the end of inspiration and the end of expiration. The results have showed that clinical target volume (CTV) coverage is compromised markedly due to respiration. The paper suggests a real-time respiratory gating system and adjustable dramatic multi-leaf collimator should be adopted in lung cancer cases for heavy ion radiotherapy with small CTV-to-PTV margin","PeriodicalId":14377,"journal":{"name":"International Review of Biophysical Chemistry","volume":"26 1","pages":"103-108"},"PeriodicalIF":0.0,"publicationDate":"2013-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74302898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When linked to a gel permeation chromatography system, they become even more powerful tools, providing information on molecular weight averages and their distributions (polydispersity). LALLS has essenttially been superseded by the development of on-line MALLS and size-exclusion chromatography (SEC)/MALLS systems, which have facilitated the greater application of light scattering theory in structure elucidation. For example, the determination of root mean square radii, molecular conformation and structure, branching ratios etc., are now readily achievable. This paper reviews the “theoretical backbone” of light scattering methods and the technology available for use in this particular aspect of macromolecular characterisation. Particular emphasis is placed on the use of SEC/MALLS and SEC/LALLS for the molecular weight elucidation of polysaccharides (such as carrageenans, starch, hyaluronic acid and dextrans), proteins, and the examination of branching in large macromolecular structures","PeriodicalId":14377,"journal":{"name":"International Review of Biophysical Chemistry","volume":"93 1","pages":"84-95"},"PeriodicalIF":0.0,"publicationDate":"2013-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73740014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is true in both the rapidly growing cities and in the rural areas. The World Health Organization (WHO) indicates that more than half of the world’s population does not have access to adequate health care services. This is due to the fact that poor people neither have access to nor could afford the present health care services. Therefore, innovative alternative approaches are needed to solve this problem. Medicinal plants offer alternative remedies with tremendous opportunities. They not only provide access and affordable medicine to poor people; they can also create income, employment and foreign exchange for developing countries. Many traditional healing herbs and plant parts have been shown to have medicinal value, especially in the rural areas and that can be used to prevent, alleviate or cure several human diseases. One of the important traditional plant used in treatment of various types diseases is Boswellia serrata. In this present review we have given emphasis on the traditional uses, phytochemistry and pharmacology of Boswellia serrata, HPTLC method was used to find out boswellic acid from Boswellia serrata","PeriodicalId":14377,"journal":{"name":"International Review of Biophysical Chemistry","volume":"119 1","pages":"74-83"},"PeriodicalIF":0.0,"publicationDate":"2013-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85635100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Normal hexane was used as solvent for the extraction. 63.05g of oil was extracted from 275g of pawpaw seeds to give oil yield of 22.93%. Lyed methanol in 60% excess was reacted with the heated oil with thorough agitation for some minutes. Fuel properties such as cloud point, API gravity, cetane number, diesel index etc were found not only to be competitive with biodiesel made from other oils but also meet some of the requirements of the ASTM Standards (American Standard for Testing and Methods ) against which biodiesel must be measured and therefore fits to be used as a blend with fossil fuel diesel in trucks and other machineries. This paper however intends to draw the attention of researchers and policy makers through thorough experimentation on a forgotten resource (pawpaw seed oil) and its suitability as a major feedstock for biodiesel production so as to conserve the fossil fuel and further create a balance between food security and energy security","PeriodicalId":14377,"journal":{"name":"International Review of Biophysical Chemistry","volume":"1 1","pages":"12-18"},"PeriodicalIF":0.0,"publicationDate":"2013-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89668319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
