Stem cells have enormous potential in health and medical research due to their ability to differentiate into specialized cells and to self-renew. Applications can be seen in cell-based therapies, e.g. for the treatment of Parkinson's disease, type I diabetes, arthritis, burn victims, and cardiovascular diseases, as well as in tissue engineering of artificial organs, development and testing of d...

The genetic analysis of development has revealed the importance of small sets of interacting genes in most morphogenetic processes. The results of gene interactions have so far been examined intuitively. This approach is largely sufficient when one deals with simple interactions, a feedback circuit for example. As more components become involved, however, it is difficult to make sure that the i...

Email: [email protected] Abstract: Bioprinting, an additive manufacturing technique, has become the cynosure of research and industry world alike. This emerging technology holds the promise of constructing artificial tissues and organs in future. This paper overviews the current state in bioprinting technology, distinguishes between different types of techniques and describes the bio-in...

sternum, spine, ilium, carpus, metacarpus, phalanges of fingers, tarsus, metatarsus, and phalanges of toes. Tubercular affections of the skin.?Such as lupus. Tubercular disease of membranes.?Such as pleurisy, peritonitis, and meningitis. Tubercular disease of certain organs.?Such as the kidneys, testis, tonsils, larynx and even tubercle of lung, considering that the best treatment for it at one...

A 50-year-old man was transferred to a level I trauma center for penetrating injury. Industrial metal had penetrated his trunk, and he injured in internal organs. The organs were treated by the surgery team. peritoneum reconstructed with artificial dermal matrix graft. wound managed negative-pressure therapy, several debridement procedures performed. full-thickness abdominal defect covered mono...

background: cytomegalovirus (cmv), a problematic virus in solid organ transplant recipients (sotr) such as liver, can worsen overall mortality and transplant outcome, so its prevention and treatment is a key of success in such patients. this study is aimed to compare the efficacy of ganciclovir (gcv) and valganciclovir (vgc) for prevention and treatment of infection with cmv. materials and meth...

background & aim: st john's wort (hypericum perforatum l.) contains hypericin and hyperforin as the main components of the extract that binds with gaba and sigma opioid receptors. this herb has many pharmacological effects, including analgesic, sedative, soothing, antispasmodic, anticonvulsant, anti-depressant, and anti-bacteria. in this study examined the effect of two concentrations of hy...

To attach reliably on various inclined rough surfaces, many insects have evolved both claws and adhesive pads on their feet. However, the interaction between these organs still remains unclear. Here we designed an artificial attachment device, which mimics the structure and function of claws and adhesive pads, and tested it on stiff spheres of different dimensions. The results show that the att...
