Because of their specific properties, vegetal fibers are increasingly used as sustainable polymer reinforcements for eco-composites. Nevertheless, polar character hinders them from being more frequently at industrial scale due to incompatibility with mostly dispersive polymers (the cheapest and most common ones). In this study, direct fluorination treatment was carried out covalently graft fluo...

Natural killer (NK) cells have the ability to mediate both bone marrow rejection and promote engraftment, as well as the ability to elicit potent anti-tumor effects. However the clinical results for these processes are still elusive. Greater understanding of NK cell biology, from activating and inhibitory receptor functions to the role of NK cells in allogeneic transplantation, needs to be appr...

BACKGROUND Situs inversus is a rare congenital anomaly characterized by the complete inversion of thoracic and abdominal organs. Liver transplantation in such patients or from donors in situs inversus is technically challenging because of the reversed anatomic structures. A small number of successful liver transplantation cases concerning situs inverus in either recipients or donors have been r...

Twenty-five pairs of male rabbits of the same variety and strain were joined together in aural parabiosis for 13 to 15 days and then separated from one another. Thirteen pairs of the separated parabiotic twins were surgically united for a second period of parabiosis, less successful than the first due to deficient healing and spontaneous separation of tissue in 5 to 15 days at the site of anast...

BACKGROUND Bioabsorbable implants are not widely used in spine surgery. This study investigated the clinical and radiological findings after anterior cervical discectomy and fusion (ACDF) in an ovine animal model with an experimental bioabsorbable cage consisting of magnesium and polymer (poly-ϵ-caprolactone, PCL) in comparison to a tricortical bone graft as the gold standard procedure. MATER...

Abstract Background A vast variety of factors may cause recurrent pregnancy loss. Blood group incompatibility of parents could cause abortion. The examination of couples or twins, blood groups showed that the blood group incompatibility can affect adversely the outcome of pregnancy. Couples with blood group incompatibility are more involved in spontaneous miscarriage. Antigenes in two differe...

IT is always regarded as axiomatic that there is no possibility of a corneal graft being successful unless the donor material comes from an animal of the same species (Nizetic, 1934; Duke-Elder, 1938; Lister, 1951; Avello, 1951; etc.), but this dogma is open to question. Ortin (1914, 1916, 1931) performed penetrating grafts on rabbits, using donor material from other species; in every case a pe...

Previously we have described a mutant Hfr strain in which incompatibility between the integrated F factor and an autonomous F-prime (F') factor was abolished. The mutation (inc) was located in the integrated F factor. F-prime factors isolated from the mutant Hfr strain have the same incompatibility behavior as those isolated from normal Hfr strains. Reintegration of these F' factors into the ch...
