Abstract It was analyzed the genetic variability of (1) three strains of a pathogenic fungi of the genus Metharhizium anisopliae var anisopliae, named MA22, MA24 and MA25, brand spesifik^®; (2) two strains of the product Metasaven^®, named MA1A and MAII; one strain of the product Metatron^®; and a native strain named MACN. This latter strain was directly isolated from the insect chapulin (Brachystola magna), from the farmer, corn plots in Durango, located in north central Mexico. Studies were conducted in the laboratory of molecular biology of the Technological Institute of the Valley of Guardiana in Durango, Mexico, from… More >

Abstract Currently, the search for chemical markers related to the botanical origin of honey is an important issue because of its potential use as a complementary tool for melisopalinological analysis. The objective of this research was to compare the (1) volatile compounds of Quillaja saponaria Mol. (Fam. Quillajaceae) floral nectar with those of unifloral honey of this same species, and (2) volatile compounds in Q. saponaria honeys from the same geographical origin. For the identification and semiquantification of volatile compounds, Gas Chromatography with Mass Spectrometry (GC-MS) was performed. The nectar of Q. saponaria presented volatile compounds different from the… More >

Abstract Chenopodium album is a very polymorphic, cosmopolitan, annual herb that grows spontaneously in modified soils in wasteland in the outlying urban zones of Bahía Blanca. In this city, the flowering period is mainly during February and March, which coincides with the highest concentrations of this pollen type in the atmosphere of the city. The objective of this study was to characterize the pollen grains of Chenopodium album, both morphologically and immunochemically, that were obtained from three different zones in the urban area of Bahía Blanca. Samples were collected from the three separate zones in the city that… More >

Abstract The electromechanical impedance (EMI) method is one of the many nondestructive evaluation approaches proposed for the health monitoring of aerospace, civil, and mechanical structures. The method consists of attaching or embedding one or more wafer-type piezoelectric transducers (PZTs) to the system of interest, the host structure, and measuring certain electrical characteristics of the transducers. As these characteristics are also related to the impedance of the host structure, they can be used to infer the mechanical properties of the monitored structure. In the study presented in this paper, we utilize the EMI to monitor the quality… 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 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… More >

Abstract As well known, gradient theories can describe size effects that are important in nano-scale problems. In this paper, we analyze the Eshelby-type anti-plane inclusion problem embedded in infinite dielectric body by considering both strain gradient and electric field gradient effects to account for the size effect and high-order electromechanical coupling effect. The size-dependent Eshelby and Eshelby-like tensor, strain, stress, electric field and electric displacement components are derived explicitly by means of Green's function method. Theoretical results indicate that strain and electric field are decoupled for anti-plane inclusion problem while stress field and electric displacement are More >

Abstract The present study aims to evaluate the mechanical properties of steel fiber reinforced concrete (SFRC) by the statistical second-order two-scale (SSOTS) method. At first, the representation for microstructure of SFRC is described by a concept of statistical screen. According to the microstructure representation, the SSOTS method is displayed in a concise way. This method is on the basis of asymptotic expansion homogenization and Monte Carlo method, and can calculate the local strain and stress field through the two-order displacement solution. As the classical homogenization method, the expression of homogenized elastic modulus is derived analytically. Then More >

Abstract During orthodontic treatments, applied mechanical forces create strain and result in tooth movement through the alveolar bone. This response to mechanical strain is a fundamental biological reaction. The present study evaluated the effect of equiaxial strain within the range of orthodontic forces on the osteogenic differentiation of human dental pulp stem cells (hDPSCs). Following isolation and culture of hDPSCs, 3rd passage cells were transferred on a silicone membrane covered with collagen. Cell adhesion to the membrane was evaluated under scanning electron microscope (SEM). Cells were divided into three groups: the first group was placed in… More >
