Hepatitis C virus (HCV) infection is a major worldwide problem. Chronic hepatitis C is recognized as one of the major causes of cirrhosis, hepatocellular carcinoma, and liver failure. Although new, directly acting antiviral therapies are suggested to overcome the low efficacy and adverse effects observed for the current standard of treatment, an effective vaccine would be the only way to certai...
Polyhydroxyalkanoates, or PHAs, belong to a class of biopolyesters where the biodegradable PHA polymer is accumulated by microorganisms as intracellular granules known carbonosomes. Microorganisms can accumulate using wide variety substrates under specific inorganic nutrient limiting conditions, with many carbon-containing coming from waste low-value sources. PHAs are universally thermoplastic,...
In both humans and animals, controversy exists concerning the duration of protection induced by BCG vaccine against tuberculosis (TB) and whether revaccination enhances protection. A long-term study was undertaken to determine whether BCG-vaccinated calves would be protected against challenge with Mycobacterium bovis 2½ years after vaccination and to determine the effect of revaccination after ...
BACKGROUND Fluorescence activated cell sorting (FACS) is a powerful technique for the qualitative and quantitative detection of biomolecules used widely in both basic research and clinical diagnostic applications. Beads displaying a specific antigen are used to bind antibodies which are then fluorescently labelled using secondary antibodies. As the individual suspension bead passes through the ...
Biomaterials are the main focuses of scientists’ efforts to develop new materials to replace or repair bone tissues [1]. Biomaterials are natural or synthetic materials which can interface with biological systems allowing the increase, repair or even the replacement of tissues and organs of the human body [2]. Within biomaterials, the polymers can be natural or synthetic as well. The main polym...
