Background: Many people suffer from nerve injury. The time consuming nature of the treatments makes the condition worse. Therefore, finding a way to accelerate the process of nerve repair is very important.Objective: To determine the effect of ultrasound on the acceleration of crushed peripheral nerve regeneration.Methods: The experimental model included crushed rat’s sciatic nerve. 40 rats w...

Erythrocyte counts, blood volume, hemoglobin, and hematocrit determinations on a series of dogs suffering from experimental pneumonia induced by the tracheal insufflation of Bacillus bronchiseplicus and Bacillus mucosus capsulatus indicate that in this condition there is an actual loss of circulating erythrocytes, without compensatory regeneration. Postmortem examination of the organs of these ...

Regeneration of normal shape, architecture, and function of craniofacial tissues following congenital abnormality, trauma, or surgical treatment presents special problems to tissue engineering. Because of the great variations in properties of these tissues, currently available treatment options fall short of adequate care. We propose that the engineering of personalized bone graft customized to...

The paper presents an algorithm of adaptation by successive mesh regeneration and its application to the potential nonlinear flow problems. The Newton-Raphson method is applied to the solution of nonlinear problem. The Kutta-Zhukovsky condition is implemented by the penalty function method. The adaptation algorithm is based on the modification of mesh size function depending on the error indica...

Conventional methods of pear breeding, largely based on intra- and inter-specific hybridization, are difficult because pear is highly heterozygous, polygenic and has a long juvenile period. Genetic improvements of pear cultivars are possible through induction of mutations and gene transfer by genetic engineering. A general prerequisite for these approaches is to establish an efficient plant reg...

Blindness is one of the most devastating condition for mankind. Regenerative medicine through tissue engineering and optimizing tissue regeneration through local adult stem cell differentiation or stem cell transplantation has received a lot of attention. This review presents highlights in the discovery of ocular stem cell and in vivo experiment for stem cell transplantation and current trends ...

Ischemic heart disease is a common condition and a leading cause of mortality and morbidity. Macrophages, besides their role in host defense and tissue homeostasis, are critical players in the pathophysiological processes induced by myocardial infarction. In this article we will summarize the current understanding of the role of monocytes and macrophages in myocardial damage and cardiac remodel...
