In the present frame of work, Macrophomina phaseolina is encapsulated in silica matrices at various concentrations by low temperature sol-gel technique using tetraethylorthosilicate (TEOS) as precursor. The optical and photophysical properties of these samples have been studied by second harmonics of Nd:YAG laser at 532 nm. UV-visible absorption spectra of(More)
INTRODUCTION Archival tissue samples preserved in formalin are a great source of treasure for biomedical research and diagnostics. Formalin, though is a good preservative, causes the modification of nucleic acid limiting the application of fixed tissues. The present study evaluated three methods of RNA extraction for constitutive gene expression and(More)
Schiff's base ligand(L) hydrazine carboxamide, 2-[3-methyl-2-thienyl methylene] and its metal complexes have been synthesized and characterized by elemental analysis, molar conductance, various spectroscopic techniques such as electronic, IR, (1)H NMR, mass, EPR. Molar conductance of complexes in DMF solution corresponds to non-electrolyte. Complexes have(More)
Objective: To develop a reliable, ecofriendly procedure for bioreduction of silver nanoparticles by Aspergillus flavus. Methods: Characterization was done by using UV-VIS spectrophotometry, Infrared spectroscopy (FT-IR) and X-ray diffraction. Results: IR spectroscopy showed the potential biomolecule responsible for the reduction of silver nanoparticles and(More)
Ni(II) and Cu(II) complexes of 2-carboxybenzaldehyde thiosemicarbazone (L) were synthesized and investigated by their spectral and analytical data. These newly synthesized complexes have a composition of M(L)X(H2O)2 (where M=Ni(II), Cu(II) and X=Cl(-), NO3(-), CH3COO(-)) and (L) is the tridentate Schiff base ligand. The ligand and its complexes have been(More)
Thermal ALD deposited Al2O3 films on silicon show a marked difference in surface passivation quality as a function of annealing time (using a rapid thermal process). An effective and quality passivation is realized in short anneal duration (∼100 s) in nitrogen ambient which is reflected in the low surface recombination velocity (SRV <10 cm s(-1)). The(More)
Streptokinase (SK) is a potent clot dissolver but lacks fibrin clot specificity as it activates human plasminogen (HPG) into human plasmin (HPN) throughout the system leading to increased risk of bleeding. Another major drawback associated with all thrombolytics, including tissue plasminogen activator, is the generation of transient thrombin and release of(More)
Seasonal pattern in relation to culicine fauna of Rohtak district of Haryana--India studied for two successive years i.e. from October 1988 to September 1990 is presented. A total of seven culicine species in the descending order of their densities were Cx. quinquefasciatus > Cx. tritaeniorhynchus > Ae. aegypti > Cx. vishnui/Ma. uniformis > Cs. fuscanus >(More)
For selectively excited calcium K X-rays in rice saplings, the relations alpha = N(KR)[1 + A gamma + B beta/(1 + alpha)] and 1/N(Ca) = alpha/beta + b + c beta are found to support the enhancement of potassium K X-rays and N(Ca) calcium K X-ray counts during potassium and calcium determinations, respectively. Here alpha, beta and gamma are weight fractions(More)
Cubital fossa is the usual site for performing venepuncture in the clinical settings for health screenings and diagnostic purposes. This procedure is simple and uncomplicated but occasionally can lead to bleeding and pain in the form of complex regional pain syndrome. Superficial veins of the upper limb are often used for venepuncture for transfusion(More)
