We carried out an in vivo study to evaluate the potential usefulness of a novel bioengineered bone substitute for the repair of palate defects in laboratory rabbits, using tissue-engineering methods. Our results showed that the use of a bioengineered bone substitute was associated with more symmetrical palate growth as compared to the controls, and the(More)
In this work we performed a study of cytokeratin (CK) expression profiling on human artificial oral mucosa developed in vitro by tissue engineering at different stages of maturation (from immature to well-developed stages) at the protein and mRNA levels. Human artificial oral mucosa was generated in the laboratory using fibrin-agarose biomaterials. As(More)
Numerous experiments have yielded contradictory results on the harmful action of magnetic fields on embryonic development. Pulsed magnetic fields appear to be able to delay normal development of embryos. In the present study, fertilized Gallus domesticus eggs were exposed during incubation to pulsed magnetic fields (harmonic signals of 10 µT for 1 second(More)
The objective of this study was to assess the auditory performance of the neural structures in response to controlled electrical stimulation period. A prospective cohort study focused on the intracochlear electrical stimulation parameters and hearing performance of patients suffering different cochlear malformations who were treated by cochlear implants(More)
Several studies have focused on the cartilaginous, articular, and ligamentous development of the craniovertebral joint (CVJ), but there are no unifying criteria regarding the origin and morphogenetic timetable of the structures that make up the CVJ. In our study, serial sections of 53 human embryonic (n = 27) and fetal (n = 26) specimens from O'Rahilly(More)
Gallbladder duplication is a rare congenital anomaly, with an incidence of 1 in 3,800 autopsies. The correct diagnosis and treatment of this type of entity is important in clinical practice, because it may cause some clinical and surgical problems. In this report, we present the clinical case of a 28-year-old female with abdominal pain. Ultrasound of the(More)
Because of the pleiotropic effects of statins, it may potentially be used as a locoregional adjuvant in vascular revascularization, tissue engineering, and regenerative procedures. Electron probe X-ray microanalyses and oligonucleotide microarrays were used to identify the global effects of micromolar concentrations of atorvastatin on the gene expression(More)
Although several studies have been published regarding the morphology and anatomical variations of the human shoulder joint, most have dealt with adult individuals. Those looking into the development of the joint have been focused on specific structures or have observed specimens in advanced gestational stages. The goal of this paper is to perform a(More)
The purpose of this study was to compare the effects of five different cryopreservation protocols on the histology of bioengineered tissues. Although several artificial tissues have been developed to the date by tissue engineering, classical histological analysis methods and techniques must be optimized for these new tissues with special properties. The(More)
OBJECTIVE To determine and compare specific factors that could be associated and predictive with successful prosthetic rehabilitation in major lower-limb amputations. METHODS A 15-year long (2000-2014) retrospective observational cohort study was conducted. Two different criteria were used to define successful prosthetic rehabilitation: (1) the ability to(More)
