25. Physicochemical characterization, carotenoid content and protein digestibility of pumpkin access flours for food application
Abstract Pumpkin (Cucurbita maxima) research has been growing because of its characteristics, such as the attractive color, low-cost production, nutritional potential, and functional properties for food application. In this context, pumpkin processing for flour production provides a full possibility for the consumption of this vegetable, being thus an altern

26. Hybrid Hydrogels Based on Polyethylene Glycol Bioconjugated with Silylated-Amyloidogenic Peptides
Hybrid-peptide hydrogel arrangements are a promising alternative to obtaining biocompatible structures at the nanoscopic scale. In this work, a new class of hybrid hydrogels was obtained through the sol-gel process based on the reaction between an amyloid-like octapeptide sequence [RF]4 (where R = arginine and F = phenylalanine) covalently bonded with glycin

27. Evaluation of autolysis induced histologic alterations in skeletal muscle tissue of non-traditional meat animals
Abstract Raw meat is characterized by various natural cellular processes that lead to its chemical content alteration. The purpose of the present study is to evaluate autolysis induced histologic alterations in skeletal muscle tissue of cow elk. In this study the authors used skeletal muscle tissue of 2-year-old cow elk. The tissue was sampled from m. quadri

28. OTIMIZAÇÃO DO PROCESSO NÃO INVASIVO E NÃO DESTRUTIVO DE EXTRAÇÃO E ANÁLISE DE METABÓLITOS VOLÁTEIS DE MAMÃO PAPAIA POR SPME-GC-MS
The analysis of volatiles is an alternative in the routine of quality control of fruits, since the volatile metabolites can change in the presence of microorganisms. A well-established method for extracting volatiles is the solid phase microextraction (SPME). This work aims to define some parameters (fiber coating, conditioning time and fiber exposure time)

29. Effect of ultrasound on the functional and structural properties of hydrolysates of different bovine collagens
Abstract The ultrasound effect on functional and structural properties of hydrolysates of different bovine collagens (fibers, gelatines and hydrolysates) was evaluated. The enzymatically hydrolyzed samples (enzyme Alcalase®) with previous or simultaneous ultrasound treatment presented higher number of bands with shorter wavelengths (mid-FTIR). The ultrasoun

30. Quality of pasta made of cassava, peach palm and golden linseed flours
Abstract The possibility of industrially producing new types of pastas based on other types of flour than wheat has raised interest for enabling the use of widely available materials and providing adequate products to persons with celiac disease. A mixture design was developed with the purpose of preparing a gluten-free dry using cassava starch, peach palm m

31. Innovation, research and development on the passion fruit peel flour: bibliometric approach
Abstract The passion fruit peel flour, retrieved from the drying and milling of fruit-processing residues, is rich in fibers. In fact, it is an important food source, featuring many benefits for the human organism. Current study forwards a scientific and technological evaluation of the passion fruit peel flour development through bibliometric indicators. Dat

32. CELLULOSE NANOFIBERS FROM CASSAVA AGRO-INDUSTRIAL WASTE AS REINFORCEMENT IN PVA FILMS
Cellulose nanofibers (CNF) have been applied in composite systems due to the abundance of raw material, excellent mechanical and thermal properties. In this work, CNF was prepared from agroindustrial waste and used in specified amounts in polyvinyl alcohol (PVA) composites. The FTIR spectra of CNF, chemically purified cellulose (CPC) and Cassava Agro-industr

33. TERAPIA FOTODINÂMICA EM ELETROFIAÇÃO: REVISÃO DE TÉCNICAS E APLICAÇÕES
Electrospinning is a strand of nanoscience for the production of fibers in nano and micrometric scales and when combined with other techniques it becomes a powerful tool for application in various branches of science. A promising combination of electrospinning is photodynamic therapy (PDT) and photodynamic inactivation of microorganisms (PDI) for the manufac

34. Pseudoxanthoma elasticum-like papillary dermal elastolysis in non-exposed skin,
Abstract Pseudoxanthoma elasticum-like papillary dermal elastolysis is an acquired elastic tissue disorder clinically similar to pseudoxanthoma elasticum in the absence of systemic involvement. Histopathologically, special staining of elastic fibers demonstrates a total or partial band-like loss of elastic fibers in the papillary dermis. Although ultraviolet

35. Multiple whitish papules on the posterior neck of an elderly woman,
Abstract White fibrous papulosis of the neck is a rare entity, with fewer than 50 cases described. It is a benign pathology whose main interest lies in its broad differential diagnosis, especially with pseudoxanthoma elasticum. The authors report the case of a 77-year-old woman with multiple yellow-white monomorphic papules on the posterior cervical region,

36. Safety of local anesthetics,
Abstract Local anesthetics are essential medications for the conduction of dermatological procedures. They stop the depolarization of nerve fibers and are divided into two main categories, the amide and ester types. Systemic toxicity with reflex on the central nervous and cardiovascular systems is their most feared adverse reactions, and the anaphylactic rea
