ARV drugs were the largest component of overall ART costs in all settings (64%, 50% and 47% in LIC, LMIC and UMIC, respectively). Of 26 ART studies, 14 reported the drug regimes used, and only one study explicitly reported second-line treatment costs. The second cost driver was laboratory cost in LIC and LMIC (14% and 20%), and personnel costs in UMIC (26%). Two ART studies specified the types of laboratory tests costed, and three studies
specifically included above facility-level personnel costs. Three studies reported detailed PMTCT costs, and three studies reported on paediatric ART.
There is a paucity of data on the full unit BMN 673 in vitro costs for delivery of ART and PMTCT, particularly for LIC and middle-income countries. Heterogeneity in activities costed, and insufficient detail regarding components included in the costing, hampers standardization of unit cost measures. Evaluation of programme-level unit costs would benefit from international guidance
on standardized costing methods, and expenditure categories and definitions. Future work should help elucidate the sources of the large variations in delivery unit costs across settings with similar income and epidemiological characteristics.”
“Whey, a by-product of cheese making, contains whey proteins, lactose, vitamins, and minerals. Whey and whey proteins are still not fully used. In this study, see more whey protein-based aqueous polymer-isocyanate (API) adhesives were developed and characterized by bond test, Fourier transform infrared (FTIR) spectroscopy, and scanning electron microscope (SEM) for bond strength, chemical structures, and morphology. The optimized whey protein-based API adhesive for Glulam had a 28-h boilingdry-boiling wet strength of 6.81 MPa and a dry strength of 14.34 MPa.
Results indicated that the addition of polyvinyl acetate emulsion can prolong the work life of the API adhesive. Addition of crosslinker polymeric methylene bisphenyl diisocyanate (P-MDI) not only increased the cohesive strength of the cured adhesive by crosslinking whey proteins but also resulted Selonsertib in strong chemical bonds via urethane linkage in wood bondlines. Addition of polyvinyl alcohol (PVA) further increased the crosslinking density of the cured adhesive due to its capability of crosslinking whey proteins through the reaction with P-MDI. Nanoscale CaCO(3) powder (3.5 wt %) as filler significantly improved bond strength due to its mechanical interlock with the polymers in the adhesive. SEM examinations confirmed that both PVA and nanoscale CaCO3 improved the compatibilities of the components in the optimized whey protein-based API adhesive. FTIR results revealed that P-MDI reacts mainly with the residual amino groups rather than the hydroxyl groups of whey proteins. (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 120: 220-225, 2011″
