This study was aimed to evaluate the preventive role of phytic acid on lysosomal enzymes in isoproterenol (ISO)-induced myocardial infarction (MI) in male Wistar rats. Rats subcutaneously injected with ISO (85mg/kg) at an interval of 24h for two days showed a significant increase in the activities of lysosomal enzymes (glucuronidase, N-acetyl glucosaminidase, galactosidase, cathepsin-B and cathepsin-D) were increased significantly in serum and the heart of ISO-induced rats, but the activities of glucuronidase and cathepsin-D were decreased significantly in the lysosomal fraction of the heart. Pretreatment with phytic acid (25 and 50mg/kg) daily for a period of 56d positively altered activities of lysosomal hydrolases in ISO-induced rats. Thus, phytic acid possesses a cardioprotective effect in ISO-induced MI in rats. © 2015 Informa Healthcare USA, Inc. All rights reserved: reproduction in whole or part not permitted.

Development of disease treatment and preventive measures to avoid any dangerous outbreak of epidemic proportions are important. Modern methods of detection and treatment include tissue culture, nanotechnology, radiation, and laser technology. We report the synthesis of nanocrystalline materials by combustion method with the use of Aloe vera extract powder. Addition of ZnO changes the structural and optical properties of A. vera. The as-prepared nanocrystalline ZnO (ZnO + A. vera) powders were characterized using XRD, TEM, and SEM. Antibacterial and antifungal tests show that ZnO nanoparticles mixed with A. vera are effective in inhibiting bacterial growth. © 2015, Universiti Malaysia Perlis. All rights reserved.

Spectroscopic and theoretical quantum chemical studies of 2,5-dihydrothiophene-1,1-dioxide and 3-methyl-2,5-dihydrothiophene-1,1-dioxide have been carried out by FTIR and FT-Raman spectral techniques along with B3LYP methods. The geometry of the compounds have been optimised by B3LYP method with 6-311++G(d,p) and cc-pVTZ basis sets. The geometrical parameters obtained at B3LYP levels have been compared with the experimental values. Molecular electrostatic potential surface, total electron density distribution and frontier molecular orbital are constructed at B3LYP/cc-pVTZ level to understand the electronic properties. The charge density distribution and sites of chemical reactivity of the molecules have been obtained by mapping electron density isosurface with electrostatic potential surfaces. Natural bond orbital analysis of the molecules are carried out and the occupancies and the atomic hybrid contributions are calculated. © 2015 Elsevier B.V. All rights reserved.

Melaminium glutarate monohydrate has been synthesised and FTIR and FT-Raman spectral investigations are carried out. The molecular geometry and vibrational frequencies of melaminium glutarate monohydrate in the ground state have been determined by using B3LYP method with 6-31++G**, 6-31++G and cc-pVDZ basis sets. The stability of the system, inter molecular hydrogen bonding and the electron donor-acceptor interactions of the complex have been investigated by using natural bonding orbital analysis. It reveals that the N-H⋯O and O-H⋯O intermolecular interactions significantly influence crystal packing of this molecular complex. The glutarate anion forms hydrogen bonds to the melaminium cation as the proton donor of the type N-H⋯O with a distance (N⋯O) = 2.51 Å. It is also linked by other hydrogen bonds to the water molecule of the type O-H⋯O with (O⋯O) = 2.82 Å and to the amino (NH2) group of melaminium cation of the type N-H⋯O with (N⋯O) = 2.82 Å as the proton acceptor. The electrostatic potential of the complex is in the range +1.892e × 10-2 to -1.892e × 10-2.

The crystals of 1,3-diammonium propylselenate monohydrate (DAPS) were prepared and characterised X-ray diffraction (XRD), FT-IR, FT-Raman spectroscopy, and DFT/B3LYP methods. It comprises protonated propyl ammonium moieties (diammonium propyl cations), selenate anions and water molecule which are held together by a number of hydrogen bonds and form infinite chains. The XRD data confirm the transfer of two protons from selenic acid to 1,3-diaminopropane molecule. The DAPS complex is stabilised by the presence of O-H⋯O and N-H⋯O hydrogen bonds and the electrostatic interactions as well. The N⋯O and O⋯O bond distances are 2.82-2.91 and 2.77 Å, respectively. The FT-IR and FT-Raman spectra of 1,3-diammonium propyl selenate monohydrate are recorded and the complete vibrational assignments have been discussed. The geometry is optimised by B3LYP method using 6-311G, 6-311+G and 6-311+G∗basis sets and the energy, structural parameters, vibrational frequencies, IR and Raman intensities are determined.

Information science plays a vital role in each and every field of science and technology, but it is facing several difficulties to handle the data and information, a main problem is data uncertainty, several theories are dealing with uncertainty, soft set theory also do vital role to handle this uncertainty problem. This paper analysed soft set reduction and how a sample dataset is converted into binary valued information system, and also analysed how binary valued information can be used to reduce dimension of data to take better decisions. © 2013 IEEE.
