Functional characterisation and permeation studies of lyophilised thiolated chitosan xerogels for buccal delivery of insulin.

Protein Pept. Lett. 21(11) , 1163-75, (2014)

Stable and mucoadhesive, lyophilised, thiolated chitosan xerogels, loaded with insulin for buccal mucosa deliv- ery, in place of the currently used parenteral route have been developed. The xerogels w...

Vacuolar-ATPase isoform a2 regulates macrophages and cytokine profile necessary for normal spermatogenesis in testis.

J. Leukoc. Biol. 96(2) , 337-47, (2014)

a2V is required for maturation of sperm. The decreased expression of a2V at the feto-maternal interphase causes poor pregnancy outcome. The present study examined the role of a2V in spermatogenesis an...

Hemocompatibility evaluation of small elastomeric hollow fiber membranes as vascular substitutes.

J. Biomater. Appl. 29(4) , 557-65, (2014)

One of the main challenges for clinical implementation of small diameter vascular grafts (SDVGs) is their limited hemocompatibility. Important design specifications for such grafts include features th...
