Abstract
Accurately printing customizable scaffolds is a challenging task because of the complexity of bone tissue composition, organization, and mechanical behavior. Graphene oxide (GO) and poly-L-lactic acid (PLLA) have drawn attention in the field of bone regeneration. However, as far as we know, the Fischer-Koch model of the GO/PLLA association for three-dimensional (3D) printing was not previously reported. This study characterizes the properties of GO/PLLA-printed scaffolds in order to achieve reproducibility of the trabecula, from virtual planning to the printed piece, as well as its response to a cell viability assay. Fourier-transform infrared and Raman spectroscopy were performed to evaluate the physicochemical properties of the nanocomposites. Cellular adhesion, proliferation, and growth on the nanocomposites were evaluated using scanning electron microscopy. Cell viability tests revealed no significant differences among different trabeculae and cell types, indicating that these nanocomposites were not cytotoxic. The Fischer Koch modeling yielded satisfactory results and can thus be used in studies directed at diverse medical applications, including bone tissue engineering and implants.

Abstract
Carbon nanostructures application, such as graphene (Gr) and graphene oxide (GO), provides suitable efforts for new material acquirement in biomedical areas. By aiming to combine the unique physicochemical properties of GO to Poly L-lactic acid (PLLA), PLLA-GO filaments were produced and characterized by X-ray diffraction (XRD). The in vivo biocompatibility of these nanocomposites was performed by subcutaneous and intramuscular implantation in adult Wistar rats. Evaluation of the implantation inflammatory response (21 days) and mesenchymal stem cells (MSCs) with PLLA-GO took place in culture for 7 days. Through XRD, new crystallographic planes were formed by mixing GO with PLLA (PLLA-GO). Using macroscopic analysis, GO implanted in the subcutaneous region showed particles' organization, forming a structure similar to a ribbon, without tissue invasion. Histologically, no tissue architecture changes were observed, and PLLA-GO cell adhesion was demonstrated by scanning electron microscopy (SEM). Finally, PLLA-GO nanocomposites showed promising results due to the in vivo biocompatibility test, which demonstrated effective integration and absence of inflammation after 21 days of implantation. These results indicate the future use of PLLA-GO nanocomposites as a new effort for tissue engineering (TE) application, although further analysis is required to evaluate their proliferative capacity and viability.

Abstract
Klippel-Feil syndrome (KFS) is a rare congenital abnormality characterized by a short neck, a low posterior hairline, and limited head movement. Occasionally, patients with KFS may also show signs of deafness, intellectual disability, cardiac malformation, palpebral ptosis, facial nerve paralysis, cleft palate, and scoliosis. Although some researchers have documented this syndrome, scant attention has been paid to craniomaxillofacial manifestations and dental treatment of patients with KFS. The objective of this case report was to describe the planning and execution of dental treatment for a 10-year-old male patient with KFS.

Abstract
Goldenhar syndrome is a well-known condition featuring the following triad of anomalies: ocular abnormalities, microtia and vertebral anomalies. This syndrome involves structures arising from the first and second branchial arches. Craniofacial anomalies, including mandibular, zygomatic and/or maxillary hypoplasias are found in 50% of patients with Goldenhar syndrome. Patients with this syndrome may present unilateral or bilateral underdevelopment of the mandible. Several treatments for the correction of the dento-facial deformity have been described, among them distraction osteogenesis is one that shows promising results. Distraction osteogenesis is the process of bone formation that occurs during slow separation of the segments of bone after an osteotomy and it has been used to alleviate facial asymmetry. Mandibular distraction osteogenesis has been applied for many years, but long-term reports present controversial results. The purpose of the case report is to describe the immediate and long-term effects of distraction osteogenesis used to treat mandible asymmetry in a 5-year-old boy with Goldenhar syndrome.

Abstract
Low-frequency CTL and low-titer IgM responses against tumor-associated Ag MUC1 are present in cancer patients but do not prevent cancer growth. Boosting MUC1-specific immunity with vaccines, especially effector mechanisms responsible for tumor rejection, is an important goal. We studied immunogenicity, tumor rejection potential, and safety of three vaccines: 1) MUC1 peptide admixed with murine GM-CSF as an adjuvant; 2) MUC1 peptide admixed with adjuvant SB-AS2; and 3) MUC1 peptide-pulsed dendritic cells (DC). We examined the qualitative and quantitative differences in humoral and T cell-mediated MUC1-specific immunity elicited in human MUC1-transgenic (Tg) mice compared with wild-type (WT) mice. Adjuvant-based vaccines induced MUC1-specific Abs but failed to stimulate MUC1-specific T cells. MUC1 peptide with GM-CSF induced IgG1 and IgG2b in WT mice but only IgM in MUC1-Tg mice. MUC1 peptide with SB-AS2 induced high-titer IgG1, IgG2b, and IgG3 Abs in both WT and MUC1-Tg mice. Induction of IgG responses was T cell independent and did not have any effect on tumor growth. MUC1 peptide-loaded DC induced only T cell immunity. If injected together with soluble peptide, the DC vaccine also triggered Ab production. Importantly, the DC vaccine elicited tumor rejection responses in both WT and MUC1-Tg mice. These responses correlated with the induction of MUC1-specific CD4+ and CD8+ T cells in WT mice, but only CD8(+) T cells in MUC1-Tg mice. Even though MUC1-specific CD4+ T cell tolerance was not broken, the capacity of MUC1-Tg mice to reject tumor was not compromised.
