Abstract Artesunate, an antimalarial drug, has been shown to inhibit the release of inflammatory mediators
in various disease conditions. The present study was carried out to evaluate the anti-edematogenic effect of artesunate in the rat paw edema model. Inflammation was induced in the hind paw of rat by sub-plantar injection of
0.1 mL of 0.5% carrageenan and the paw volume was measured up to a fixed mark just before the injection and
then after 3 h. The difference in two volumes gave a measure of edema formation. At 3h the level of TNF-α, PGE2
and myeloperoxidase were estimated in the inflamed… More >

Abstract Field collected roots of four populations of Sida rhombifolia were used for preparing aqueous decoctions at two concentrations: 4g/L; and 16g/L. Afterwards, we used three groups of six onion (Allium cepa)
bulbs for testing each population. Slides were made with all bulbs through the smashing technique. Cells in all
phases of the cell cycle of A. cepa were analyzed. The mitotic index (% of cells in mitosis) was calculated, and
the statistical analysis through the χ2 test was carried out at 5% probability. The results showed that the aqueous
extracts of S. rhombifolia have antiproliferative activity at high concentrations. Practically… More >

Abstract Cell-based biosensors have become a research hotspot in the biosensors and bioelectronics fields.
The main feature of cell-based biosensors is immobilization of living cells on the surface of transducers. Different
types of polymers which are used as scaffolds for cell growth should be biocompatible and should have reactive functional groups for further attachment of biomolecules. In this work, cell attachment and proliferation
on chitosan hydrogel, chitosan-gelatin and gold nanoparticle-chitosan nanocomposite membranes was studied. Characterization of the membranes was performed using scanning electron microscopy (SEM) and Fourier
transform infrared spectroscopy (FTIR). Cytotoxicity assessment on HEK293 cells was carried out for all… More >

Abstract Inhibins play important roles in the reproductive system. To evaluate whether inhibin α (1-32)
fusion protein plays a role in cervical cancer growth, the plasmid pVAX-inhα was constructed and its effect on
proliferation and apoptosis of the human cervical cancer cell line (Hela) was checked by flow cytometry and
real-time PCR. The expression and localization of inhibin α protein were detected by RT-PCR and confocal microscopy which showed that inhibin α protein was expressed and localized in the nucleus of Hela cells. Over expression of inhibin α gene significantly induced cell apoptosis and ceased S phase of cell cycle. Furthermore,… More >

Abstract Ischemia-reperfusion injury is a determinant in liver injury occurring during surgery, ischemic
states and multiple organ failure. The pre-existing nutritional status of the liver, i.e., fasting, might contribute to
the extent of tissue injury. This study investigated whether alanine, an amino acid precursor of glucose, could
protect ex vivo perfused livers of fasting rats from reperfusion injury. The portal vein was cannulated, the liver removed and perfused in a closed ex vivo system. Isolated livers were perfused either with glucose 1 g/L and 10 g/L,
or with equal concentrations of alanine (n = 10 in each group). The experiment consisted… More >

Abstract The aims of this study were to determine the meiotic behavior and to estimate pollen grains viability in bean (Phaseolus vulgaris L.) cultivars. Flower buds were collected during different developmental stages
of the Mesoamerican bean cultivars IAPAR 44, Guapo Brilhante, BRS Expedito, BRS Valente, Guateian 6662
and Pérola, and the Andean bean cultivar Iraí, grown in a greenhouse. The meiotic index was determined by
anther squashing of material fixed in absolute ethanol-glacial acetic acid (3:1) and stained with acetic orcein.
No meiotic abnormalities were observed and the meiotic indices were high for all cultivars, indicating that the
mismatch generated during… More >
