Solitary Fibrous Tumor of the Mandible.

A 41-year-old woman presented with a facial asymmetry in the mental region and a painful, well-circumscribed, tender mass in the right lower buccal vestibule, associated with extensive ill-defined bone rarefaction with subtle cortical bone resorption. Microscopically, a proliferation of bland spindle cells interspersed with collagen fibers and prominent staghorn-like blood vessels was observed. Immunohistochemical analysis revealed strong positivity for CD34, Bcl-2, CD99, and STAT-6, confirming the diagnosis of Solitary Fibrous Tumor (SFT).

Random Convolutional Kernel Transform with Empirical Mode Decomposition for Classification of Insulators from Power Grid.

The electrical energy supply relies on the satisfactory operation of insulators. The ultrasound recorded from insulators in different conditions has a time series output, which can be used to classify faulty insulators. The random convolutional kernel transform (Rocket) algorithms use convolutional filters to extract various features from the time series data.

Pressurized liquid extraction of bioactive compounds from grape peel and application in pH-sensing carboxymethyl cellulose films: A promising material to monitor the freshness of pork and milk.

This study produced pH-sensing carboxymethyl cellulose (CMC) films functionalized with bioactive compounds obtained by pressurized liquid extraction (PLE) of grape peel to monitor the freshness of pork and milk. A semi-continuous PLE was conducted using hydroethanolic solution (70:30, v/v) at a flow rate of 5 mL/min, 15 MPa, and 60 °C. The films were produced by the casting technique using CMC (2.

Application of nanoparticles entrapped orange essential oil to inhibit the incidence of phytopathogenic fungi during storage of agroecological maize seeds.

The demand for sustainable, healthy, and pesticide-free food has grown in recent years. Agroecological seeds cannot receive chemical treatment, as pesticides present toxicological and environmental risks, requiring the development of alternative methods for disease control, such as the use of essential oils. In this study, orange essential oil was extracted and encapsulated in zein nanoparticles by the nanoprecipitation method.

Optimized EWT-Seq2Seq-LSTM with Attention Mechanism to Insulators Fault Prediction.

Insulators installed outdoors are vulnerable to the accumulation of contaminants on their surface, which raise their conductivity and increase leakage current until a flashover occurs. To improve the reliability of the electrical power system, it is possible to evaluate the development of the fault in relation to the increase in leakage current and thus predict whether a shutdown may occur. This paper proposes the use of empirical wavelet transform (EWT) to reduce the influence of non-representative variations and combines the attention mechanism with a long short-term memory (LSTM) recurrent network for prediction.

Production of methylcellulose films functionalized with poly-ε-caprolactone nanocapsules entrapped β-carotene for food packaging application.

Nowadays, there is a worldwide demand in the production of innovative packaging that release active compounds to increase the shelf life of perishable food products. Therefore, this study produced methylcellulose films functionalized with poly-ε-caprolactone nanocapsules entrapped β-carotene. The nanoparticles were produced by the nanoprecipitation method, and 10, 30, and 50 % of nanoparticles colloidal solution was added in the methylcellulose filmogenic solution.

Application in situ of biodegradable films produced with starch, citric pectin and functionalized with feijoa (Acca sellowiana (Berg) Burret) extracts: An effective proposal for food conservation.

In this study, biodegradable films produced with starch, citric pectin, and functionalized with antioxidant compounds from feijoa (Acca sellowiana (Berg) Burret) were in situ applied for the conservation of ground beef, bread, and grapes. The results demonstrated that the films produced were an excellent source of stable antioxidant compounds, with antimicrobial activity against Escherichia coli, Salmonella, and Shigella. The bioactive films based on biological macromolecules positively stabilized the polyunsaturated fatty acids and deterioration reactions in ground beef.

Chitosan packaging functionalized with Cinnamodendron dinisii essential oil loaded zein: A proposal for meat conservation.

The nanoencapsulation of essential oils for biodegradable films functionalization is a viable alternative for the production of active food packaging. In this study, the Cinnamodendron dinisii Schwanke essential oil was nanoencapsulated using zein as wall material, and applied in chitosan matrix to produce an active nanocomposite film packaging for food conservation. The chemical composition of the Cinnamodendron dinisii Schwanke essential oil showed a variety of unexplored bioactive compounds, and 1,8-cineole was the major compound.

Feijoa [Acca sellowiana (Berg) Burret] accessions characterization and discrimination by chemometrics.

Background: Feijoa [Acca sellowiana (Berg) Burret] is a Brazilian native fruit with few commercial-level plantations and high agroindustrial potential. A genotype evaluation experiment was conducted from 1996 onward, aiming to obtain fruits based on the agronomical parameters; however, the selection based on chemical composition had not been evaluated with respect to developing a new cultivar. Accordingly, the present study aimed to discriminate seven accessions of feijoa in terms of nutritional composition, phenolic compounds and antioxidant activity using multivariate analysis (principal component analysis and multivariate contrast), targeting the potential production of a new cultivar with better nutritional value and high antioxidant capacity.

Malignant peripheral nerve sheath tumor of the lower labial mucosa: case report and literature review.

Malignant peripheral nerve sheath tumor (MPNST) is an uncommon soft tissue sarcoma with a predilection for the extremities and trunk of adults, rarely occurring in the oral cavity. To date, 10 cases of MPNSTs affecting the lower labial mucosa have been reported in the English language literature. We describe an additional case of MPNST in the lower labial mucosa of a 67-year-old male patient, who exhibited a painful swelling with a history of 4 months of evolution.

Adipose-Derived Stem Cells Decrease Bone Morphogenetic Protein Type 2-Induced Inflammation In Vivo.

Purpose: Recombinant human bone morphogenetic protein type 2 (rhBMP-2) has been used to promote bone regeneration. In contrast, some reports have suggested rhBMP-2 does not provide advantages over autogenous bone grafting owing to the undesirable postoperative symptoms of this growth factor. Because the undesirable symptoms of rhBMP-2 are usually promoted by inflammation, this study evaluated the in vivo effect of human adipose-derived stem cells (ASCs) incorporated into polylactic co-glycolic acid (PLGA) scaffolds in decreasing the inflammatory response induced by a low dose of rhBMP-2.

Prospective tomographic evaluation of autogenous bone resorption harvested from mandibular ramus in atrophic maxilla.

Autogenous bone is considered the criterion standard for grafting procedures of severely resorbed alveolar ridges. However, the rate of autogenous graft resorption remains controversial. The aim of this study was to evaluate the mandibular graft resorption with cone beam computed tomography after 10 and 180 days of augmentation procedures in the atrophic maxilla.

Tomographic follow-up of bone regeneration after bone block harvesting from the mandibular ramus.

Autogenous bone is still considered the gold standard, and the applicability of autogenous bone grafts is well established. However, the possibility of second harvesting from the same donor region remains unclear. The aim of this study was to perform a prospective evaluation of hard tissue deposition in the mandibular ramus after bone block harvesting using cone beam computed tomography (CBCT).
