Abstract Background Dithranol, a standard drug for psoriasis, has lured keen attention by virtue of its antioxidant, anti-proliferative and anti-inflammatory activities. However, poor stability solubility critically impair the formulation design, evaluation administration. To improve these issues, dithranol was encased in ?-cyclodextrin nanosponges using solvent evaporation technique. Previousl...

Amino acids are the building blocks of proteins, but they also have nutritional and therapeutic values and are becoming popular as dietary supplements (1). These molecules also find wide applications in protein research and biotechnology product development. The idea that they could have value in such applications stems from the use of certain amino acids and other low– molecular-weight organic...

Enzymes subjected to freeze-thawing are known to be protected by polymers that are preferentially excluded from the hydrated surface of proteins [reviewed in Carpenter et al. (1994) ACS Symp. Ser. 567, 134-147]. Preferentially excluded solutes are also known to stabilize quaternary structure, which enhances the thermostability of multimeric proteins in aqueous systems. Also, it has been suggest...

Tannins and their toxic effects against various decay organisms have been interrelated for centuries. As natural products gained more interest, waste from several production fields abundant in tannins has yielded promising components wood preservation. In this work, the main approach was to split condensed into smaller fractions by chemical hydrolysis evaluate suitability beech impregnation. Co...

DNA extraction is the first committed step in every molecular biological endeavour. This biomolecule can be isolated from any material for subsequent downstream processes. Most available protocols nucleic acid entail use of either lyophilized tissues or liquid nitrogen tissue grinding. These procedures pose a major limitation such protocols, especially parts world where and freeze-dryer are not...
