regenerative medicine provides substitutes for organ transplantation, which is restricted in applicability due to immune responses against allograft and the large discrepancy between the need for organs and the number of available transplantation. an artificial environment is allowing cells to induce tissue regeneration. growth factors (gfs) play a significant role in the cell fates in their mi...

The artificial transmission of Cowdria ruminantium with infected blood, organ homogenates, peritoneal macrophages, tick stabilate and tissue culture cells is discussed. Organ homogenates prepared from the myocardium, spleen, kidneys and liver of diseased animals are commonly used to infect mice. The efficacy of organ homogenates as a source of C. ruminantium depends on factors such as the route...

3D printed biomaterials are increasingly used in cell cultures and drug screens. Given the ease of creating artificial tissues, will this technique revolutionize biomedicine and organ implants in the future?

ABSTRACT This paper presents a bio-artificial pancreas fabricated with self-assembled, precisely structured 3D microcontainers on a rolled-up alginate sheet. We utilize a novel 3D membrane approach developed in our laboratory to package pancreatic βcells so that they can be transplanted and function like an autonomous insulin-producing organ. Our approach provides stable and adequate diffusion ...

Organ transplantation is the procedure of replacing diseased organs, parts of organs, or tissues by healthy organs or tissues. The transplanted organ or tissue can be obtained either from the patient himself (= autograft), from another human donor (= allograft) or from an animal (= xenograft). Transplanted organs may be artificial or natural, whole (such as kidney, heart and liver) or partial (...

We propose to develop advanced parallel geometric and numerical algorithms and software for simulating complex flows with dynamic interfaces. The development of scalable, parallel highaccuracy algorithms for simulating such flows poses enormous challenges, particularly on systems with thousands of processors. We will use the resulting tools to simulate blood flow in artificial heart devices. Th...

background: care of brain dead donors is complex, critical, and sensitive and has a direct and positive impact on the end result of organ and tissue transplantation process. this study describes the nurses’ experiences of care of brain dead donors in intensive care units (icu). materials and methods: this research was performed by phenomenological method that is a qualitative approach. purposiv...

The skin is a multifunctional organ that protective, self healing and sensing many forms of artificial have also been developed, having properties functionalities approximating to natural skin. Artificial can be formed by biological substances as well non-biological substances. This article maps out the structural difference between skin, need for formation which very useful treating patients w...

In recent years, significant progress has been made in organ transplantation, surgical reconstruction, and the use of artificial prostheses to treat the loss or failure of an organ or bone tissue. In recent years, considerable attention has been given to carbon nanotubes and collagen composite materials and their applications in the field of tissue engineering due to their minimal foreign-body ...
