Tracheal slices incubated with radioactive precursors in tissue culture medium secrete labeled mucus glycoproteins into the culture medium. We have used an in vivtro approach, a combined method utilizing exposure to pneumotoxins in vivo coupled with quantitation of mucus secretion rates in vitro, to study the effects of inhaled pollutants on mucus biosynthesis by rat airways. In addition, we ha...

The corrosion definition is not constrained to alloy and metals, but rather the term, corrosion, can likewise be stretched out to earthenware production and other nonmetallic materials. Corrosion can prompt to problems significant in furthest fields for man-factory [1]. Corrosion gets to be distinctly a standout amongst the most difficult points for researchers and the society for building. Fro...

Interpenetrating network (IPN) beads of sodium carboxymethyl xanthan (SCMX) and sodium alginate (SAL) were prepared by ionotropic gelation process using AlCl3 as a cross-linking agent. The effect of different formulation variables like total polymer concentration, gelation time, concentration of cross-linking agent, and drug load on the extent of release of ibuprofen (IBP), a non steroidal anti...

Grafting of vinyl monomers onto cellulose is an important tool for the modification of cellulose. Depending on the monomer grafted onto cellulose, it gains new properties. The grafting can be performed in heterogeneous or homogeneous medium. In the grafting performed in heterogeneous medium, the reaction is carried out in aqueous medium using a suitable initiator. As initiator, the radiation or...
