Research in urethane-acrylate UV-curables has shown that these materials have mechanical properties inferior to those of thermoplastic polyurethanes with very similar composition owing to the high cross-link density in UV-curables; in particular, their ultimate extension is low (less than 100%). Past attempts a t increasing the ultimate extension involved compromising the advantages of the UV-c...

Commercially available automated cell counters based on trypan blue dye-exclusion are widely used in industrial cell culture process development and manufacturing to increase throughput and eliminate inherent variability in subjective interpretation associated with manual hemocytometers. When using these cell counters, sample dilution is often necessary to stay within the assay measurement rang...

Nine different formulations were prepared from the prepolymer, 2,2-bis-[4-(2-hydroxy-3-acryloxy prop-1-oxy)phenyl] propane with various functional diluents namely, monofunctional diluent, Di(ethylene glycol)ethylether acrylate, difunctional diluent, tri(ethylene glycol) dimethacrylate and trifunctional diluent, trimethylolpropane ethoxylate (1-ethoxylate/hydroxyl) triacrylate in the presence of...

The present work was aimed at formulating a SMEDDS (Self-microemulsifying drug delivery system) for oral drug delivery system containing flutamide. The solubility of flutamide was determined in various vehicles. Pseudo ternary phase diagram was constructed to identify the micro emulsification existence area. SMEDDS formulations were tested for microemulsifying properties, and the resultant form...

Background: Hen egg yolk is a common component of most semen cryopreservation extenders. However, diluents containing the egg yolk may have adverse effects on the quality of the semen. Egg yolk could be solubilized by the addition of sodium dodecyl sulphate (SDS) in semen extenders. Many studies have shown beneficial effects of antioxidants addition to semen freezing extenders. Antioxidants are...

Agricultural residues such as Maize Husk, Groundnut Shell, Coconut Shell and Sugarcane Bagasse were collected, sorted, dried ground to particulate fillers. The various fillers characterized in terms of density, moisture content pH value. Single ordinates 150 µm particle size 30 parts per hundred rubber (pphr) loading respectively adopted for all filler types. They used alongside with convention...

In the dispensing process, powdered medicines are often blended with diluents or different kinds of powder. With blending, the mass percent of the medicine in the mixture is unknown until the active pharmaceutical ingredient is determined with techniques such as spectroscopy and chromatography. However, pharmacists need to confirm the exact blending ratio of the dispensing mixture in pharmacies...

This study evaluates the hypothesis that ethanol alone, or in diluents for drugs used to protect hypoxic mice, is responsible in part for an increased tolerance to hypoxia (4-5% oxygen). The change in hypoxic tolerance following i.v. or i.p. administration of ethanol, diazepam, nimodipine and various diluent components was measured. Diazepam (50 mg/kg i.v.) increased hypoxic tolerance to 700 +/...

Conventional solid dosage form suffers from problem like difficulty in swallowing with age, onset of action and physiological factor of patient like gastric emptying time. To overcome this mouth dissolving tablet is a newer approach to drug delivery. Zolpidem is preferentially used for the short term treatment of insomnia. The aim of present study is to formulate and evaluate mouth dissolving t...

The ability to cryopreserve spermatozoa from all of the domestic species is challenging. Even though all of the cells must endure similar physical stresses associated with the cryopreservation processes, sperm from the different species are very different in size, shape and lipid composition, all of which affect cryosurvival. Thus, when a cryopreservation protocol has been optimized for sperm o...
