Biomedical engineering is a new area of research in medicine and biology, providing new concepts and designs for the diagnosis, treatment and prevention of various diseases. There are several types of biomedical engineering, such as tissue, genetic, neural and stem cells, as well as chemical and clinical engineering for health care. Many electronic and magnetic methods and equipments are used f...

Living humans are unique among the animal kingdom with respect to their ability to externalize mental representations outside the brain through a variety of media and in a recursive or creative manner (i.e., generating a potentially infinite array of combinations). Earlier humans evolved two specialized organs—the hand and the vocal tract—as primary instruments for externalizing artificial or s...

Minimal access surgery (MAS), also known as keyhole surgery, offers many advantages over the more traditional open surgery. However, it possesses one very significant drawback–– the loss, by the surgeon, of the ‘‘sense of feel’’ that is used routinely in open surgery to explore tissue and organs within the operative site. Because of this, important properties such as tissue compliance, viscosit...

objective(s):  the field of nanotechnology is rapidly expanding .the development quantum dots quantum dot (qds), show great promise for treatment and diagnosis of cancer and targeted drug delivery little data on the toxicity of qds, especially for in vivo applications, are available. as a result, concerns exist over their toxicity for in vivo applications. then, cytotoxic effects of cadmium sel...

BACKGROUND The aim of this paper was to study the prevalence and intensity of Anisakids larvae in the long tail tuna fish captured from Iranian shores of Persian Gulf. METHODS Different organs including skin, abdominal cavity, stomach and intestinal contents, stomach sub serous tissues, liver, spleen, gonads and 20 grams of muscles of 100 long tail tuna fish (Thannustonggol) caught from water...

A variety of gene transfer technologies have been devised as tools for functional analysis of genes as well as gene therapy and regenerative medicine. Electroporation enables efficient genetic transfection in vivo into various organs as well as tumors without the aid of any infectious viral vector, and has been applied to preclinical nonviral gene therapy approaches. The efficacies of transfect...

Ultraviolet light from sunlight unfolds a variety of different photophysical and photochemical activities in human skin, which are controlled and reacted upon by two photoendocrinologically active antagonistic organs in the brain, namely the pituitary and pineal gland, under the control of the eye. There are also two organs for light reception, namely skin and eye. These systems have been attun...

Purpose Intra-fractional organs at risk (OARs) deformations can lead to dose variation during image-guided adaptive brachytherapy (IGABT). The aim of this study was to modify the final accepted brachytherapy treatment plan to dosimetrically compensate for these intra-fractional organs-applicators position variations and, at the same time, fulfilling the dosimetric criteria. Material and metho...

Nowadays, polymer nanofibers have gained attention due to remarkable characteristics such as high porosity and large surface area to volume ratio. Among their fabrication methods, electrospinning technique has been attracted as a simple and reproducible approach. It is a versatile, simple and cost-effective technique for the production of continuous nanofibers with acceptable characteristics su...

The most vital organs in the human body are brain, heart, and lungs. Because brain controls coordinates operations of all other organs, normal function is vital. Brain tumour a mass tissues which interrupts functioning if left untreated will lead to death subject. classification multiclass tumours using spatial fuzzy based level sets artificial neural network (ANN) techniques proposed this pape...
