Background: Hepatitis B virus is one of the causes major health problem throughout world. vaccine way to control HBV infections effectively. The prevalence HB infection shows a decreased effectivity vaccination. Objective: To discover differences in anti-HBs levels between two schedules vaccination recommended by Indonesian Pediatric Society (at 2, 4, 6 months vs 3, 4 age). Met...
To elucidate gene expression pathways underlying age-associated impairment in influenza vaccine response, we screened young (age 21-30) and older (age≥65) adults receiving influenza vaccine in two consecutive seasons and identified those with strong or absent response to vaccine, including a subset of older adults meeting criteria for frailty. PBMCs obtained prior to vaccination (Day 0) and at ...
The advent of thermostable enzymes has led to great advances in molecular biology, such as the development of PCR and ligase chain reaction. However, isolation of naturally thermostable enzymes has been restricted to those existing in thermophylic bacteria. Here, we show that the disaccharide trehalose enables enzymes to maintain their normal activity (thermostabilization) or even to increase a...
BACKGROUND The concerted action of three complementary cellulases from Clostridium thermocellum, engineered to be stable at elevated temperatures, was examined on a cellulosic substrate and compared to that of the wild-type enzymes. Exoglucanase Cel48S and endoglucanase Cel8A, both key elements of the natural cellulosome from this bacterium, were engineered previously for increased thermostabil...
Introdution: An estimated 3% of the world population is chronically infected with hepatitis C virus (HCV), and it is a major health problem that causes cirrhosis and hepatocellular carcinoma. Despite the new directly acting antivirals (DAAs) for curing chronic hepatitis C virus (HCV) infection, the control of the disease has remained a global challenge. Several reasons, including presence of as...
Ricin toxin (RT) is the second most lethal toxin known; it has been designated by the CDC as a select agent. RT is made by the castor bean plant; an estimated 50,000 tons of RT are produced annually as a by-product of castor oil. RT has two subunits, a ribotoxic A chain (RTA) and galactose-binding B chain (RTB). RT binds to all mammalian cells and once internalized, a single RTA catalytically i...
Thermostable α-amylases hold a very important place in commercial industrial applications Sri Lanka. Therefore, the main aim of this study was to identify superior Bacillus strain and optimize growth conditions that could yield high α-amylase production. Three strains, B. amyloliquefaciens ATCC 23350, licheniformis 14580 megaterium 14581 were used for study. Shake flask culture experiments cond...
A phase I randomized, double-blind, placebo-controlled trial was done with a cytomegalovirus (CMV) vaccine based on the envelope glycoprotein, gB, combined with a novel adjuvant, MF59. Participants received CMV gB vaccine with MF59 or CMV gB with alum or placebo at 0, 1, and 6 months. A fourth vaccine was given at 12 months to a subgroup. Levels of neutralizing antibody and antibody to gB 2 wee...
Dengue virus (DENV) is one of the most widespread arboviruses. The four DENV serotypes infect about 400 million people every year, causing 96 million clinical dengue cases, of which approximately 500'000 are severe and potentially life-threatening. The only licensed vaccine has a limited efficacy and is only recommended in regions with high endemicity. We previously reported that 2'-O-methyltra...
