1. Green synthesis and Characterization of ZnO-CoFe2O4 Semiconductor Photocatalysts Prepared Using Rambutan (Nephelium lappaceum L.) Peel Extract
In this work, the semiconductor of ZnO-CoFe2O4 composites were prepared by green synthesis approach using rambutan peel extract (Nephelium lappaceum L.) as a capping agent. X-ray diffraction patterns of composites showed the main peaks of ZnO at 2θ = 31.8°, 34.5°, and 36.2° corresponding to hexagonal wurtzite structure and weak peak at 2θ = 35.4° for c

2. Dynamic Arrays Based on Magnetically Controlled Particles: Synthesis and Application
Growth mechanisms of dynamic granular arrays based on magnetically controlled particles are presented. Method of the external rotating magnetic field (ERMF), based on a dipole interaction of magnetic spherical Fe3O4 particles in highly ordered volume arrays is proposed and a design for its practical implementation is developed. The magnetic assembly can resu

3. IMOBILIZAÇÃO DE DIÓXIDO DE TITÂNIO EM DIFERENTES MATERIAIS SUPORTE PARA O EMPREGO EM FOTOCATÁLISE HETEROGÊNEA
The technological bottleneck for the application of heterogeneous photocatalysis with titanium dioxide (TiO2) is the retention and reuse of the catalyst, which brings opportunities for studying techniques for its immobilization on solid supports. The main objective of this paper was to test different methods to effectively immobilize TiO2 on granular activat

4. Synthesis and cytotoxicity evaluation of granular magnesium substituted β-tricalcium phosphate
Objective The aim of this study was to produce dense granules of tricalcium phosphate (β-TCP) and magnesium (Mg) substituted β-TCP, also known as β-TCMP (Mg/Ca=0.15 mol), in order to evaluate the impact of Mg incorporation on the physicochemical parameters and in vitro biocompatibility of this novel material. Material and Methods The materials were char

6. Anatomia foliar de espécies de Flacourtiaceae (Sleumer 1980) / Foliar anatomy from species of Flacourtiaceae (Sleumer 1980)
There is no agreement regarding the taxonomic organization of the Flacourtiaceae and the theme is not emphasized in the literature, since there is a lack of taxonomic studies on this family. Several authors point out the close relationship between the families Flacourtiaceae and Salicaceae. Numerous families of plants have members with medicinal uses, standi

7. Estudo clinico-molecular e analise da textura epidermica de pacientes com sindrome de Sjogren-Larsson / Molecular genetic study and texture analysis of the epidermis in patients with Sjogren-Larsson Syndrome
Background: Sjögren-Larsson syndrome (SLS) is an autosomal recessive disorder characterized by ichthyosis, mental retardation, and spasticity. Various mutations in the ALDH3A2 gene that codes for fatty aldehyde dehydrogenase (FALDH) are responsible for the disease but the genotype-phenotype relationships are undefined. Objectives: The purpose of this study

8. Synthesis control and characterization of hydroxyapatite prepared by wet precipitation process
Several techniques have been utilized for the preparation of hydroxyapatite (HA) and other calcium phosphates for the development of biomaterials. It is vital to know the reaction kinetics to be able to control the material obtained by the aqueous solution route. In the present work, HA has been produced by different wet precipitation processes and different

10. Adaption to Hyperoxia: INFLUENCE ON PROTEIN SYNTHESIS BY LUNG AND ON GRANULAR PNEUMOCYTE ULTRASTRUCTURE
We studied the influence of prolonged exposure to hyperoxia (O2 > 98%) on protein synthesis and on the ultrastructure of the granular pneumocyte. To study protein synthesis, as indicated by l-[U-14C]-leucine incorporation into protein, lung slices were incubated with radioactive leucine and a surface-active fraction was obtained by ultracentrifugation of lun

11. Degradation of dipalmitoyl phosphatidylcholine by isolated rat granular pneumocytes and reutilization for surfactant synthesis.
We investigated metabolic utilization of exogenous (modelled after lung surfactant) phospholipids by granular pneumocytes in primary culture. Cells were incubated for 21, 65, and 140 min with [3H-methyl]dipalmitoylphosphatidylcholine (DPPC) containing liposomes prepared from synthetic lipids. Radioactivity in cellular phosphatidylcholine (PC) declined steadi

12. Volumetric alterations in tonofibrils during epithelial differentiation in hamster cheek pouch mucosa.
The present report describes the use of stereological procedures to evaluate the volume of tonofibrils present in defined epithelial strata undergoing differentiation. Hamster cheek pouch epithelium was processed for electron microscopy and, following strict sampling procedures, micrographs were obtained from basal, spinous and granular layers. Using stereol
