Evaluation of How Methacrylate Gelatin Hydrogel Loaded with L. Extract (Steam Bark) Effects Bone Repair Activity Using Rats as Models.

The use of bioactive materials, such as L., to stimulate the bone repair process has already been studied; however, the synergistic effects of its association with light emitting diode (LED) have not been reported. The present work aims to evaluate the effect of its stem bark extract incorporated into methacrylate gelatin hydrogel (GelMA) on the bone repair process using pure hydrogel and hydrogel associated with LED therapy.

Nanohydroxyapatite/Titanate Nanotube Composites for Bone Tissue Regeneration.

Strategies for the production of new nanocomposites that promote bone tissue regeneration are important, particularly those that enhance the osteoinduction of hydroxyapatite in situ. Here, we studied and report the synthesis of nanohydroxyapatite and titanate nanotube (nHAp/TiNT) composites formulated at different concentrations (1, 2, 3, and 10 wt % TiNT) by means of a wet aqueous chemical reaction. The addition of TiNT affects the morphology of the nanocomposites, decreasing the average crystallite size from 54 nm (nHAp) to 34 nm (nHAp/TiNT10%), while confirming its interaction with the nanocomposite.

Bone repair in defects filled with AH Plus sealer and different concentrations of MTA: a study in rat tibiae.

Objectives: This study aimed to evaluate the effects on bone repair of different concentrations of mineral trioxide aggregate (MTA) added to AH Plus.

Materials And Methods: Bone tissue reactions were evaluated in 30 rats () after 7 and 30 days. In the AH + MTA10, AH + MTA20, and AH + MTA30 groups, defects in the tibiae were filled with AH Plus with MTA in proportions of 10%, 20% and 30%, respectively; in the MTA-FILL group, MTA Fillapex was used; and in the control group, no sealer was used.

In vivo evaluation of bone repair guided with biological membrane based on polyhydroxybutyrate and norbixin.

The present work aimed to synthesize and verify the effectiveness of the polyhydroxybutyrate and norbixin membrane as a scaffold in bone defects induced in the tibia of rats. Twenty-four male Rattus norvegicus rats were used, divided into control and membrane groups. After anesthesia, a bone defect was induced in the right tibia, followed by the implantation of the biomaterial at the site of the lesion only in the membrane group, with euthanasia after 15 and 30 days of the experiment.

Oromandibular Limb Hypogenesis Syndrome: Overlap of Moebius and Ankyloglossia Superior With Severe Limb Defects.

The oromandibular limb hypogenesis syndromes (OLHS) represent a group of rare conditions characterized by congenital malformations involving the tongue, mandible, and limbs. In this report, we describe a newborn girl with paralysis of abducens and facial nerves, transverse agenesis of the distal segments of the limbs, micrognathia, cleft lip and palate, and ankyloglossia superior. This observation confirms an overlap between Moebius syndrome and ankyloglossia superior syndrome with severe limb defects.

Women's protection public policies: evaluation of health care for victims of sexual violence.

Violence against women has increased over the years and is a serious violation of human rights. This study aimed to evaluate public policies, women's rights legislation and health care for victims of sexual violence. This is an exploratory and descriptive study, with interviews to professionals of the Care Center for Women Victims of Violence of Teresina-PI, and collection of medical records data of victims.

Rhinoliths causing palatal perforation: case report and literature review.

Rhinoliths are calcified masses formed within the nasal cavity because of the solidification of mucus, debris, or foreign objects by gradual accretion of mineral salts. They are mostly asymptomatic and incidentally diagnosed, although some patients may complain of nasal discharge and obstruction. Ulceration of the nasal mucosa, facial swelling, and bone destruction are less frequently observed but bring about difficulties for differential diagnoses with several pathologic entities.

Maxillary lesion presenting as a first sign of multiple myeloma: case report.

Plasma cell neoplasia is a lymphoid neoplastic proliferation of B cells. This denomination encloses multiple myeloma (MM), solitary bone plasmacytoma and extramedullary plasmacytoma. MM consists of a clonal proliferation of plasma cells based in the bone marrow, with various degrees of differentiation.
