Acidic interfacial growth can provide a number of industrially important mesoporous silica morphologies including fibers, spheres, and other rich shapes. Studying the reaction chemistry under quiescent (no mixing) conditions is important for understanding and for the production of the desired shapes. The focus of this work is to understand the effect of a number of previously untested condition...
Purpose: To rationalize the use of surfactants by preparing Salbutamol sulphate microspheres using two types of surfactants, Tween 80 and Span 80 and study their effects on different characteristics of the microspheres. Methods: Microspheres containing Salbutamol sulphate was prepared by emulsion solvent evaporation technique. Infrared Spectroscopy, Differential Scanning Colorimetry and X-Ray D...
Thioglycollate Broth Medium was used for culturing the test bacteria. Thioglycollate Broth Medium containing 0.5% sodium thiosulfate, O.S^o Tween ® 80, and 0.07% lecithin was used as the transplant medium. The sodium thiosulfate inactivates free iodine which mav be carried over. The Tween ® 80 and lecithin serve as inactivators for the quaternary compounds and hexachlorophene, and thioglycollat...
A simple, precise, inexpensive and sensitive voltammetric method has been developed for the determination of gemifloxacin mesylate (GEM) in the presence of tween 80 in the bulk, farmaceutical dosage forms and human urine at gold nanoparticles modified carbon paste electrode (GNCPE). The electrochemical behavior of GEM has been investigated by using cyclic voltammetry (CV) and differential pulse...
lamotrigine is used in the treatment of cns disorders, particularly epilepsy; pain; oedema; multiple sclerosis and psychiatric indications including bipolar disorder. lamotrigine belongs to biopharmaceutical classification systems, bcs class ii (low solubility & high permeability). in addition, it requires immediate therapeutic action hence the main objective of this study is to improve the sol...
The effects of various synthetic medium components and their interactions with each other ultimately impact laccase production in fungi. This was studied using a laccase-hyper-producing marine-derived basidiomycete, Cerrena unicolor MTCC 5159. Inducible laccases were produced in the idiophase only after addition of an inducer such as CuSO(4). Concentration of carbon and nitrogen acted antagonis...
Lysozyme production is a frequent property of staphylococcal strains isolated from various sources; all 503 tested strains of Staphylococcus aureus and 13 out of 35 strains of Staphylococcus epidermidis produced an enzyme lysing Micrococcus lysodeikticus as tested by a modified plate method. Lysozyme production by staphylococci is more frequent than the production of free coagulase, clumping fa...
Uniform-sized agarose beads were prepared by emulsification technique in this study. Agarose (4% w/v) was dissolved in boiling water containing 0.9% sodium chloride and used as water phase. A mixture of liquid paraffin containing 3 wt% of tween 80 emulsifier was heated to 70-80 o C and used as oil phase. Then the heated oil phase was poured into the water phase and the mixture was stirred with ...
Fullerene nanoemulsions were formulated in palm kernel oil esters stabilized by low amount of mixed nonionic surfactants. Pseudoternary phase diagrams were established in the colloidal system of PKOEs/Tween 80 : Span 80/water incorporated with fullerene as antioxidant. Preformulation was subjected to combination of high and low energy emulsification methods and the physicochemical characteristi...
This study was conducted to estimate the prevalence of tubercular infection and compute the Annual risk of tuberculosis infection (ARTI) in Bijnor district of western Uttar Pradesh through a hospital-based tuberculin survey conducted at a pediatric hospital. A total of 1085 children below 18 years (0-4 years 866, 5-17 years 219), attending the out-patient department during October 2007 through ...
