اخبار همایشها وجلسات دفاع / 2015 TERMIS World Congress
« Last post by nourani on September 03, 2015, 05:03:47 am »
Dear All
Welcome to the 2015 TERMIS World Congress Site! The theme for the 2015 TERMIS World Congress is "Past, Present Future: The Evolution of Regenerative Medicine," reflecting the impact of tissue engineering throughout the past two decades, and focusing on the future. To this end, the 2015 scientific program will focus on the innovative technologies focused in regenerative medicine.

The TERMIS World Congress Meeting is held every three years, and brings together researchers, scientists, trainees, and students from both academia and industry to discuss critical developments in the field. The meeting is led by keynote speakers each day, and consists of parallel technical sessions as well as poster presentations. A strong role in the meeting planning and execution will be played by the TERMIS Student and Young Investigator Section (SYIS). Furthermore, there will be an emphasis on promoting the careers of women and underrepresented groups in the tissue engineering and regenerative medicine fields.

General Discussion / Antibacterial Hydroxyapatite (A review)

Substituted Hydroxyapatites with Antibacterial Properties
Joanna Kolmas et al.

Reconstructive surgery is presently struggling with the problem of infections located within implantation biomaterials. Of course, the best antibacterial protection is antibiotic therapy.However, oral antibiotic therapy is sometimes ineffective, while administering
an antibiotic at the location of infection is often associated with an unfavourable ratio of dosage efficiency and toxic effect.Thus, the present study aims to find a new factor which may improve antibacterial activity while also presenting low toxicity to the human
cells. Such factors are usually implemented along with the implant itself and may be an integral part of it.Many recent studies have focused on inorganic factors, such as metal nanoparticles, salts, and metal oxides. The advantages of inorganic factors include the
ease with which they can be combined with ceramic and polymeric biomaterials. The following review focuses on hydroxyapatites substituted with ions with antibacterial properties. It considers materials that have already been applied in regenerative medicine (e.g., hydroxyapatites with silver ions) and those that are only at the preliminary stage of research and which could potentially be used in implantology or dentistry.We present methods for the synthesis of modified apatites and the antibacterial mechanisms of various ions as well as their antibacterial efficiency.

Marketing and Tissue Engineering / Bone grafting is a big business
« Last post by nourani on April 22, 2015, 09:38:11 pm »

Bone grafting is a big business

, generating sales of more than $2.5 billion a year.1 Of the more than 3 million musculoskeletal procedures done annually in the United States, about half involve bone grafting with either an autograft or an allograft.2 Worldwide, autografts or allografts are used in approximately 2.2 million orthopaedic procedures annually3.

Triaxial Electrospun Nanofiber Membranes for Controlled Dual Release of Functional Molecules
Daewoo Han and Andrew J. Steckl
ABSTRACT
A novel dual drug delivery system is presented using triaxial structured nanofibers, which provides different release profiles for model drugs separately loaded in either the sheath or the core of the fiber. Homogenous, coaxial and triaxial fibers containing a combination of materials (PCL, polycaprolactone; PVP, polyvinylpyrrolidone) were fabricated. The drug
release profiles were simulated using two color dyes (KAB, keyacid blue; KAU, keyacid uranine), whose release in physiological solution was measured using optical absorption
as a function of time.....-

Injury in the central nervous system (CNS) is very serious and may result in permanent disability of the patients, since it causes neural cell death and tissue defects. There have been no effective therapies so far, unfortunately. Many studies have already shown that neural stem cells (NSC) can be used for treatment of certain neurological diseases because they have the intrinsic ability of self-renewal. However, the effect of NSC grafting for neural restoration has been proven to be rather limited because of low viability and undesired differentiation in vivo.
It is critical therefore, that creation of a suitable microenvironment or niche, composed of cells, blood vessels, growth factors and the extracellular matrix (ECM), would play an important role in regulating neurogenesis, survival and regeneration of NSC. Thus, certain biomaterials used for neural tissue engineering may offer a promising approach for creating
such a microenvironment, since they provide biological scaffolds which can sustain the stem cells for transplantation and neural regrowth in vivo.
Among those materials, the hyaluronic acid (HA)-based biodegradable hydrogel has been proven to mimic brain ECM effectively and to provide a good scaffold that is easily modified with different useful molecules for promoting regeneration
in the injured CNS.
