3. APROVEITAMENTO DE PRECURSORES LIGNOCELULÓSICOS PARA PRODUÇÃO DE ACETATO DE CELULOSE
The feasibility of obtaining cellulose acetate from lignocellulosic precursors is of great interest from the environmental, economic and technological points of view. Herein, sugarcane bagasse and vegetable sponge (Luffa cylindrica ) were used as precursors to produce cellulose using the organosolv extraction procedure. From the extracted celluloses, the pro

4. Hatchability of gemmules of two Neotropical freshwater sponges (Porifera: Spongillida)
RESUMO Ambientes de águas continentais estão suscetíveis a condições ambientais extremas, determinantes à evolução de várias estratégias adaptativas para estas condições variáveis. As esponjas de águas continentais produzem corpos resistentes chamados gêmulas, que contêm células totipotentes e espículas especializadas (gemoscleras). As gêm

5. lncRNA OIP5-AS1 targets ROCK1 to promote cell proliferation and inhibit cell apoptosis through a mechanism involving miR-143-3p in cervical cancer
Opa-interacting protein 5 antisense transcript 1 (OIP5-AS1) is one kind of cytoplasmic long non-coding RNA (lncRNA), which has been demonstrated to play a critical function in multiple cancers. However, the detailed mechanism of OIP5-AS1 in the regulation of cervical cancer progression is still obscure. Here, we demonstrated that lncRNA OIP5-AS1 was upregula

6. Vitrified embryo transfer in Merino sheep under extensive conditions
Abstract The aim was to evaluate pregnancy success after transfer of embryos vitrified in micropipette tips in Merino sheep under extensive conditions. A second objective was to evaluate the influence of embryo stage in such pregnancy rate. One hundred and twenty-seven embryos were rewarmed and transferred into recipient ewes. On rewarming, the embryos were

7. The effects of oleaster flour, active gluten and sucrose replacement with potassium acesulfame and isomalt on the qualitative properties of functional sponge cakes
Resumo Oleaster (Elaeagnus angustifolia L.) é uma fruta com valor nutracêutico especial, que cresce em uma ampla faixa de condições climáticas na Europa e na Ásia. No estudo atual, os efeitos da farinha de oleaster (15%, 30% e 45%) e de glúten ativo (0 e 3%) nas propriedades físicas, químicas e sensoriais de bolos tipo esponja foram avaliados. A mel

8. The influence of Aloe vera with mesenchymal stem cells from dental pulp on bone regeneration: characterization and treatment of non-critical defects of the tibia in rats
Abstract Objective This study aimed to evaluate the inflammatory effect and bone formation in sterile surgical failures after implantation of a collagen sponge with mesenchymal stem cells from human dental pulp (hDPSCs) and Aloe vera. Material and Methods Rattus norvegicus (n=75) were divided into five experimental groups according to treatment: G1) contr

9. Biotechnological Properties of Sponges from Northeast Brazil: Cliona varians as a Biocatalyst for Enantioselective Reduction of Carbonyl Compounds
To research the potential ability of whole marine sponges to act as biocatalysts, this paper describes for the first time the employment of whole Cliona varians sponge in the stereoselective reduction of prochiral a-keto esters and isatin to the corresponding chiral alcohols. The addition of D-fructose, D-glucose or sucrose remarkably increased the conversio

10. Circular RNA hsa_circ_0000523 regulates the proliferation and apoptosis of colorectal cancer cells as miRNA sponge
Among the novel class of endogenous long non-coding RNAs, circular RNA (circRNA) is known as a key regulator in the development and progression of different cancers. Its function and mechanism in the tumorigenesis of colorectal cancer, however, has not been well studied. This study thus aimed to investigate potential regulation of colorectal cancer by circRN

11. Effect of red propolis on hamster cheek pouch angiogenesis in a new sponge implant model
Abstract Purpose: To evaluate the effects of red propolis on cheek pouch angiogenesis in a hamster new model sponge implant. Methods: Forty eight animals divided into eight groups. (Groups I-IV), the animals were treated for 15 days before and 10 days after sponge implantation. (Groups V-VIII), the animals were treated for 10 days after sponge implantatio

12. CHEMICAL CONSTITUENTS DERIVED FROM THE CANARIES MARINE SPONGE Myxilla sp.
Stigmasterols, ceramides, including ceramide-1-phosphates and pyrimidines were identified in an ethanol extract of the marine sponge Myxilla sp. The compounds were identified by MS and 1D- and 2D-NMR techniques. A simple method based on an ultra-high-performance liquid chromatography coupled with tandem mass spectrometry was developed to investigate the prod
