Abstract Cancer stem cells (CSCs) are a small subpopulation of cancer cells whose resistance to chemotherapy and radiotherapy plays a pivotal role in treatment failure, tumor recurrence and metastasis. Today, the ability of many phytochemicals in targeting of CSCs has been identified. Kaempferol is a plant phytoestrogen that was recognized as a useful agent for targeting cancer cells by apoptosis induction, cell cycle arrest and inhibition of angiogenesis, migration, and invasion of cancer cells. In this study, we compared the effect of docetaxel as a common breast cancer chemotherapy drug and kaempferol on MCF-7 breast CSCs.… More >

Abstract Low pressure plasma polymer films were synthesized using pyrrole and allylamine monomers and adding iodine was used (or not) for the reaction in both cases. They were polymerized on glass substrates under the same reaction conditions. Polymerization of allylamine was also studied at different operating powers. These thin polymer films were used as culture surfaces for HepG2 cells, a cell line derived from a human hepatoma. The proliferation, differentiation and two-dimensional propagation until obtaining monolayer of the cells was studied on the different synthetized films and correlations were established between the conditions of synthesis, the More >

Abstract Focal adhesion kinase (FAK) plays a vital role in mediating the adaptability of tumor cells under mechanical stimuli. Previous studies revealed that FAK can locate to different cell compartments, and its regulation is highly dependent on its subcellular localization. However, the local FAK activities and its regulation mechanism in different cell compartments of tumor cells in response to fluid shear stress are still unclear. In this study, 5 dyn/cm² and 20 dyn/cm² of shear stress was applied to HeLa cells for 30 min. The activities of FAK targeting different subcellular compartments (lipids rafts, non-rafts, focal adhesions… More >

Abstract In this study, we propose an automatic procedure for digital image processing. We describe a method that can efficiently quantify and characterize lipid droplets distributions in different cell types in culture. Prospectively, the lipid droplets detection method described in this work could be applied to static or time-lapse data, collected with a simple visible light or fluorescence microscopy equipment. Fully automated algorithms were implemented in Octave, a freely available scientific package. More >

Abstract The digestive gland of the apple snail Pomacea canaliculata lodges two types of pigmented corpuscles (identified as C and K corpuscles) which has been proposed as endosymbiont/s. Both corpuscular types are always present in the digestive gland of adult snails, they are released into the tubuloacinar lumen and are later expelled in the feces. On their part, hatchlings lack any C or K corpuscles in the digestive gland as well as in their feces, whereas C corpuscles appear in both the gland and feces within one week after hatching. Hence, it is possible that the… More >

Abstract The testis is a double gland comprised of the sperm-producing seminiferous tubules and a complex endocrine interstice. The former structures generate and release whole cells (exocrine aspect of the gland) while the latter synthesize and release androgens and related hormones. The testis also has poorly understood paracrine connexions. These connexions play an important role during spermatogenesis. A key molecule within these structures is β-actin. Therefore, the present study aims at examining the expression pattern of β-actin during the various stages of the spermatic cycle in the rat. To achieve this goal, we used a combination More >

Abstract Current investigation has shown that human exposure to aflatoxins is not limited to the administration of contaminated cereals, but water is another possible source. This study was aimed to design easily applicable method to eliminate aflatoxin B2 (AFB2) from contaminated drinking water. Electrospinning has been used for preparation of probiotic-coated polyvinyl alcohol (PVA) and cellulose acetate (CA) nanofibers. Both of these hybrid nanofibers were studied by scanning electron microscopy (SEM) and Fourier-transformed infrared spectroscopy (FT-IR). SEM showed the proper coating of probiotic strains (Kluyveromyces lactis CBS 2359 and Saccharomyces cerevisiae ATCC 9763) on both nanofiber… More >
