Ultrasound is a high frequency mechanical vibrations mechanical waves, which has an acoustic frequencies range from 2*104 to 1010Hz in the elastic medium of propagation. It propagates as a focused beam, so it can effectively detect human tissues. In addition, when ultrasound was stopped transmitting, there would be no energy accumulation on human, which is the ideal method of diagnosis and therapy. While in the ultrasonic applications, varies effects have appeared. One of the effects is...
The purpose of this study is to evaluate the performance of a new algorithm for optimization of beam weights in anatomy-based IMRT. The algorithm uses a numerical technique called Gaussian-Elimination that derives the optimum beam weights in an exact or non-iterative way. The distinct feature of the algorithm is that it takes only fraction of a second for optimizing the beam weights, irrespective of the complexity of the given case. The algorithm has been implemented using MATLAB with a...
The use of antibiotics to control prevalent and often fatal bacterial diseases, when accompanied with good public health practices and improvements in sanitation, housing, and nutrition; significantly contributed to the increased life expectancy in the last 30 years. The phenomenal success of these new, "wonder drugs" led to their widespread use for almost every clinical application in all disciplines of health care, regardless of the indication. In an almost ironic twist, the very...
Articular cartilage, which is a form of hyaline cartilage is a biomaterial composed mainly of collagen, covers the articulating surfaces of bones [2]. Collagen is the most important structural material of hard and soft tissues in animals and operates as the bearing surfaces of joints. Cartilage is porous and its high degree of mechanical strength comes about from the movement of fluid (synovial fluid) in and out of the tissue, when forces are applied to it via joint loading [2]. The avascular...
Magnetic domain imaging has immensely contributed to the present level of studies of micro magnetic phenomena. Lots of modern techniques have been introduced now days for routine checking of magnetic imaging of magnetic nanostructures and materials. Numerous states - of - the - art techniques have been developed for imaging of the magnetic structures. Advantages and disadvantages and some special techniques are going to be discussed in the light of their applicability and complementarity for...

Section IAN INTRODUCTION TO STEM CELLSRegeneration and Repair The ability of an organism to renew and regenerate its own tissue is a significant factor in its capacity to maintain homeostasis. These new tissues originate from within the organism and are generated in response to a stimulus. They are created to repair damage and return an organism to a steady state, thus allowing the organism to continue along its genetically expressed developmental path. In order to gain a...
Ceramir Crown & Bridge (Ceramir C&B) is the main product of DOXA AB. It is the first ever invented product based on the Ceramir technology which belongs to the material group Nanostructurally Integrating Bioceramics i.e., NIB (H. Engqvista et al., 2001). Ceramir hardens by dissolving with water first which wets the tooth, and continues to recrystallize as nanocrystalline hydrates which precipitates on the wall of the tooth, creating a basic pH (L. Hermansson et al., 2003). This...
1. Introduction Apoptosis is an evolutionarily conserved, highly regulated process of programmed, active, cell death, morphologically and biochemically different from necrosis, and is important in normal development and physiological homeostasis of multicellular organisms [1, 2 and 3]. Cells dying by apoptosis maintain membrane integrity until late in the process but display several morphological and biochemical alterations, including chromatin condensation, nuclear segmentation,...
ABSTRACT The skeletal and cardiac muscles contain the Dystrophin Glycoprotein Complex, which is a multi subunit protein complex. This complex helps in the proper functioning of the skeletal and cardiac muscles. Defects in the proteins of Dystrophin Glycoprotein Complex caused due to mutations in genes encoding for them causes muscular dystrophy of various types and cardiomyopathy in some cases. The function of sarcospan (25 kDa), an integral component of the Dystrophin glycoprotein complex in...
