Vaccines can greatly reduce the spread of and deaths from many infectious diseases. However, many infections have no successful vaccines. Better understanding of the generation of protective CD8 memory T cells by vaccination is essential for the rational design of new vaccines that aim to prime cellular immune responses. Here we demonstrate that the combination of two adjuvants that are current...

Currently, there is a shortage of adjuvants that can be employed with protein subunit vaccines to enhance protection against biological threats. LT-IIb(T13I) is an engineered nontoxic derivative of LT-IIb, a member of the type II subfamily of heat labile enterotoxins expressed by Escherichia coli, that possesses potent mucosal adjuvant properties. In this study we evaluated the capacity of LT-I...

Derangements of mineral metabolism occur during the early stages of chronic kidney disease (CKD). Hyperphosphatemia develops in the majority of patients with ESRD and has long been associated with progression of secondary hyperparathyroidism and renal osteodystrophy. More recent observational data have associated hyperphosphatemia with increased cardiovascular mortality among dialysis patients....

In this work the efficiencies of the chemical and the electrochemical break-up of oil-in-water (O/W) emulsions with hydrolyzing aluminium salts are compared. It has been obtained that the efficiency of the processes does not depend directly on the dosing technology, but on the total concentration of aluminium and pH. This latter parameter changes in a different way in the chemical and the elect...

Invocation of cellular immunity by epitopic peptides remains largely dependent on empirically developed protocols, such as interfusion of aluminum salts or emulsification using terpenoids and surfactants. To explore novel vaccine formulation, epitopic peptide motifs were co-programmed with structural motifs to produce artificial antigens using our "motif-programming" approach. As a proof of con...

Since at least Roman times, salts of aluminum have been added to drinking water and surface water to reduce turbidity and improve appearance. Aluminum sulfate, Al2(SO4)3, commonly called alum, has been used extensively as a flocculating agent in the treatment of wastewater for over 100 years. In 1970, Jernelov was apparently the first to use alum to remove phosphorus from the water column of a ...

Beryllium is the fourth element in the periodic table and the second lightest metal known. Discovered as an oxide in 1798 by the French chemist L. N. Vauquelin, beryllium was first isolated in 1828, when it was called "glucinium" owing to the sweet taste of its salts. Beryllium is the lightest of all solid, chemically stable substances and has an unusually high melting point (12870C). Silver gr...

Herpes simplex virus (HSV) type 2 (HSV-2) is the main cause of genital and neonatal herpes and is highly prevalent worldwide. Previous phase I and II studies showed the immunogenicity and safety of the candidate prophylactic HSV-2 glycoprotein D-based subunit vaccine (gD2-AS04), containing aluminum hydroxide and 3-O-deacylated monophosphoryl lipid A (MPL) as adjuvant (AS04), in healthy adults. ...

Metallic monoliths were prepared by anodized aluminum-scale pilot plant, using sulfuric acid as electrolyte. Anodisation tests were conducted at different times and different temperatures of the electrolytic bath. Aluminum monolith anodized at 40oC for 30 min was selected for catalysts support. The monoliths were impregnated by two methods: i) impregnation in two stages using two Mn salts in an...

Determinations of aluminum (Al) in serum are performed routinely by laboratories through customer-validated applications. Graphite furnace atomic absorption spectroscopy (GFAAS) is one of only a few routine techniques with a dynamic range sensitive enough to be used clinically in customervalidated applications to measure Al in serum. There are a few specific analytical challenges that an analys...
