1. Complexation and enhancement of temozolomide solubility with cyclodextrins
ABSTRACT Temozolomide is a poorly soluble anti-cancer drug used in the treatment of some brain cancers. Following literature reports about the enhancement of solubility and stability for these kinds of drugs upon complexation with cyclodextrins, we aimed to form an inclusion complex between temozolomide and the different types of cyclodextrins (CDs) to enhan

2. Nanocompósitos de PVC, argila organicamente modificada e óxidos metálicos : estudo do processo de preparação e propriedades de combustão e emissão de fumaça / PVC, organically modified montmorillonite and metallic oxides nanocomposites : evaluation of the preparation process and fire and smoke behavior
Poly(vinyl chloride) (PVC), copper (II), molybdenum and zinc oxides, and organically modified montmorillonite nanocomposites were prepared in a melt blending intercalation process. The morphology of the nanocomposites was evaluated using X-ray diffractometry (XRD) and transmission electron microscopy (TEM), and indirectly by the increment of the Young modulu

3. Experimental study and simulation of the performance in an internal combustion engine fueled with diesel and ethanol. / Estudo experimental e simulação termodinâmica de desempenho em um motor de combustão interna operando com óleo diesel e etanol.
Due to a huge necessity to use alternatives fuels, this study presents an experimental performance investigation and its thermodynamics simulation (zero-dimensional) of an ignition engine Diesel cycle working with ethanol and Diesel. First of all some definitions and concepts related to internal combustion engines are given. Following this, an explanation of

4. Evidence for activation of a respiratory burst in the interaction of human neutrophils with Mycobacterium tuberculosis.
We examined the capacity of human neutrophils to develop a respiratory burst, as monitored by superoxide release, in response to interaction with Mycobacterium tuberculosis. Serum-opsonized, heat-killed mycobacteria induced significant release of superoxide from neutrophils after 30 min of exposure, with a maximum release of 34 +/- 1.7 nmol/30 min per 5 X 10

5. Augmentation of secretagogue-induced amylase secretion in pancreatic acini of heat-exposed rats.
1. The effects of prolonged heat exposure on pancreatic exocrine secretion were investigated to evaluate the involvement of the insulin-pancreatic acinar axis. Rats were kept at 34 degrees C and a relative humidity of 40% for 2 weeks with or without insulin administration. Control rats were housed at the thermoneutral temperature of 25 degrees C. By using is

6. Bacteriophage Release in a Lysogenic Strain of Agrobacterium tumefaciens1
Bacteriophage release in a lysogenic strain of Agrobacterium tumefaciens V-1 is temperature-sensitive. At 25 C and 30 C, phage was released in a ratio of 1 plaque-forming unit per 100 bacteria; at 35 C, although bacterial growth was not inhibited, phage release was suppressed. Phage synthesis was induced by heat shock, 42 C for 30 min, ultraviolet irradiatio

7. Release of outer membrane fragments from wild-type Escherichia coli and from several E. coli lipopolysaccharide mutants by EDTA and heat shock treatments.
EDTA-induced outer membrane losses from whole cells of wild-type Escherichia coli (O111:B4) and several lipopolysaccharide (LPS) mutants derived from E. coli K-12 D21 were analyzed. EDTA treatment induced losses of LPS (up to 40%), outer membrane proteins OmpA, OmpF/C, and lipoprotein, periplasmic proteins, and phosphatidylethanolamine. The extent of these r

8. Interaction of Chlamydia psittaci with mouse peritoneal macrophages.
L-cell-grown Chlamydia psittaci elementary bodies (EB) were rapidly phagocytized by mouse peritoneal macrophages in vitro. However, the intracellular fate of chlamydiae in macrophages appeared to be dependent on the multiplicity of infection (MOI), i.e., the EB-to-macrophage ratio, and the treatment of the EB. At an MOI of 1:1 or less, survival is maximal, a

9. Storage Iron Kinetics. VII. A BIOLOGIC MODEL FOR RETICULOENDOTHELIAL IRON TRANSPORT
The processing of erythrocyte iron by the reticuloendothelial cell has been characterized by kinetic measurements of blood radioactivity made after the intravenous injection of heat-damaged erythrocytes labeled with 59Fe and of transferrin-bound 55Fe. The early reticuloendothelial release of iron, a matter of hours, was calculated from the plasma turnover ra

10. Heat-induced blebbing and vesiculation of the outer membrane of Escherichia coli.
Thermal damage to the outer membrane of Escherichia coli W3110 was studied. When E. coli cells were heated at 55 degrees C in 50 mM Tris-hydrochloride buffer at pH 8.0, surface blebs were formed on the cell envelope, mainly at the septa of dividing cells. Membrane lipids were released from the cells during the heating period, and part of the released lipids

11. Adsorption of Staphylococcal Bacteriophage by Milk Proteins1
Propagation of homologous bacteriophage in a culture of Staphylococcus aureus (1:1 ratio of phage to bacteria) in Trypticase Soy Broth (TSB) and in skim milk indicated more activity of phage in TSB. Early lysis of bacteria in skim milk followed by a pronounced rise in bacterial population suggested that staphylococcal phages were being inactivated by milk. T

12. Treponema denticola Outer Membrane Inhibits Calcium Flux in Gingival Fibroblasts
Treponema denticola is a cultivable oral spirochete which perturbs the cytoskeleton in cultured cells of oral origin, but intracellular signalling pathways by which it affects actin assembly are largely unknown. As the outer membrane (OM) of Treponema denticola disrupts actin-dependent processes that normally require precise control of intracellular calcium,
