Parabolic flights allow short microgravity investigations in Physical and Life Sciences, technology instrumentation tests. The use of parabolic is complementary to other carriers, preparatory manned space missions onboard the International Space Station spacecraft, around Earth or beyond, Moon for example.
OBJECTIVE Three independent studies have shown that variation in the fat mass and obesity-associated (FTO) gene associates with BMI and obesity. In the present study, the effect of FTO variation on metabolic traits including obesity, type 2 diabetes, and related quantitative phenotypes was examined. RESEARCH DESIGN AND METHODS The FTO rs9939609 polymorphism was genotyped in a total of 17,508 ...
The association between decline in physical function and age-related conditions, such as reduced cognitive performance and vascular disease, may be explained by genetic influence on shared biological pathways of importance for aging. The apolipoprotein E (APOE) gene is well-known for its association with Alzheimer's disease, but has also been related to other disorders of importance for aging. ...
Hydrogen is a promising energy carrier, especially for transportation, owing to its unique physical and chemical properties. Moreover, the combustion of hydrogen gas generates only pure water; thus, wide utilization can positively affect human society achieve global net zero CO2 emissions by 2050. This review summarizes characteristics primary carriers, such as water, methane, methanol, ammonia...
Although molecular and physical mechanisms of fibroblast matrix assembly have been widely investigated, the role of adhesive ligand presentation on matrix assembly has only been recently probed (Pereira et al. Tissue Eng., 2007). In the present study, various-sized albumin-derived nanocarriers (ANCs) were fabricated as nanoscale organization units for functionalization with the cell adhesion do...
Physical activity enhances cognitive performance, yet individual variability in its effectiveness limits its widespread therapeutic application. Genetic differences might be one source of this variation. For example, carriers of the methionine-specifying (Met) allele of the brain-derived neurotrophic factor (BDNF) Val66Met polymorphism have reduced secretion of BDNF and poorer memory, yet physi...
We have automated a manual test for detection of heterozygotes of Tay-Sachs disease by assay of hexosaminidase A in serum, based on pH inactivation [C/in. Chim. Acta 43, 417 (1973)]. The same manifold is used both for the total hexosaminidase and pH-inactivation (hexosaminidase B) procedures. Automation expedites mass screening of the Ashkenazi Jewish population for carriers of the TaySachs gen...
Oxygen carriers play an important role in chemical looping processes to transport oxygen for fuel conversion. In this study, the defluidization phenomena of were examined under highly reducing conditions a fluidized-bed batch reactor. This is relevant chemical-looping gasification, where could be reduced significant extent compared that combustion. Only few studies have reported physical fluidi...
