1. Heterogeneous Fenton-like catalytic degradation of phenazine dye over CeO2 (CP-2) nanoscale powder
Abstract A heterogeneous Fenton-like process was explored for oxidation of phenazine dye using ceria polishing material (CP-2). XRD, SEM, FTIR, UV-vis DRS, and pHPZC techniques were applied to characterize the catalyst features. The performance of the heterogeneous Fenton-like process was investigated under various parameters (reaction time, pH, H2O2 concent

2. The protective effects of β-sitosterol and vermicularin from Thamnolia vermicularis (Sw.) Ach. against skin aging in vitro
Abstract: Aged skin, featured with dryness and wrinkles, has received mounting attention due to its adverse influences on beauty. β-Sitosterol and vermicularin are two common active ingredients of Thamnolia vermicularis (Sw.) Ach., a traditional Chinese medicine, of which the anti-aging effect has been discovered. Their protective performance against skin a

3. Plasma Treatment of Polyamide Fabric Surface by Hybrid Corona-Dielectric Barrier Discharge: Material Characterization and Dyeing/Washing Processes
In this study, the hybrid corona-dielectric barrier discharge plasma treatment was employed to modify the physical, chemical and morphological characteristics of a half-knitted fabric composed of 92% polyamide 6.6 and 8% elastane (PA). These properties of the fabric were evaluated by the water contact angle, x-ray diffraction, infrared spectroscopy, scanning

4. Mini review: immunologic functions of dual oxidases in mucosal systems of vertebrates
Resumo As células epiteliais da mucosa atuam como a primeira barreira imunológica dos organismos e entram em contato direto com os patógenos. Portanto, os hospedeiros devem ter estratégias diferenciadas para combater os patógenos de forma eficiente. Trabalhos recentes revelaram que a oxidase dupla (DUOX) desempenha um papel fundamental para a imunidade

5. Basic heel prick test: inclusion of screening, diagnosis and criteria for early confirmation of congenital infection by Toxoplasma gondii
ABSTRACT Toxoplasma gondii can cross the placental barrier, causing fetal infection with potentially severe sequelae. The aim of this study was to evaluate whether the serological screening for toxoplasmosis should be included in the basic neonatal heel prick test in order to establish criteria for the confirmation and/or exclusion of the diagnosis of congen

6. Water Susceptibility and Mechanical Properties of Thermoplastic Starch–Pectin Blends Reactively Extruded with Edible Citric Acid
Pectin and starch are edible, non-toxic, biodegradable and obtained from renewable sources. Also, have the benefit to be easily cross-linked producing hydrogels. Reactive extrusion with edible citric acid and cross linking interactions was evaluated on extruded thermoplastic in natura and cationic starch-pectin blends. Materials water susceptibility and mech

7. Propofol inhibits burn injury-induced hyperpermeability through an apoptotic signal pathway in microvascular endothelial cells
Recent studies have revealed that an intrinsic apoptotic signaling cascade is involved in vascular hyperpermeability and endothelial barrier dysfunction. Propofol (2,6-diisopropylphenol) has also been reported to inhibit apoptotic signaling by regulating mitochondrial permeability transition pore (mPTP) opening and caspase-3 activation. Here, we investigated

8. Interdiffusion studies on hot rolled U-10Mo/AA1050
The U-Mo alloys are investigated with the goal to become nuclear material to fabricate high-density fuel elements for high performance research reactors. The enrichment level (20% 235U) suggests that the U-Mo alloys should be between 6 to 10 wt. (%), which can reach up to 9 gU.cm-3 in fuel density. Nevertheless, the U-Mo alloys are very reactive with Al. Int

9. Modulation of ROS production in human leukocytes by ganglioside micelles
Recent studies have reported that exogenous gangliosides, the sialic acid-containing glycosphingolipids, are able to modulate many cellular functions. We examined the effect of micelles of mono- and trisialoganglioside GM1 and GT1b on the production of reactive oxygen species by stimulated human polymorphonuclear neutrophils using different spectroscopic met

10. Serum and cerebrospinal fluid S100B concentrations in patients with neurocysticercosis
The clinical manifestations of neurocysticercosis (NC) are varied and depend on the number and location of cysts, as well as on the host immune response. Symptoms usually occur in NC when cysticerci enter a degenerative course associated with an inflammatory response. The expression of brain damage markers may be expected to increase during this phase. S100B

11. Minimização de impactos nos recursos hídricos causados por sistemas de saneamento in situ: estudo piloto em Parelheiros - São Paulo (SP) / Minimization of septic systems impacts on groundwater resources. Pilot study in Parelheiros - São Paulo (SP)
O escopo principal desse projeto foi o de criar um conjunto de ações integradas que permitissem minimizar os impactos de sistemas de saneamento in situ nos recursos hídricos subterrâneo. Sendo as fossas sépticas, mesmo as bem construídas, pouco efetivas onde há alta densidade populacional, foi desenvolvido e aplicado no loteamento Jardim Santo Antôni

12. Morphological repercutions of burn injury components of the myenteric plexus in the jejunum of adults rats. / Repercussões morfológicas da lesão térmica corporal nos componentes do plexo mioentérico do jejuno de ratos adultos.
Burn is a determinant factor to alter body structures as the striated muscle. It also determines gastrintestinal mucosal atrophy what produce loss of selective barrier. With histochemical, immunohistochemical and light microscopy methods the myenteric plexus (MP) of the jejunum was evaluated in rats submitted to burn injury. The scalding was performed in 30%
