The structure of life's first genetic polymer is a question intense ongoing debate. “RNA world theory” suggests RNA was nucleic acid. However, ribonucleotides are complex chemical structures, and simpler acids, such as threose acid (TNA), can carry information. In principle, acids like TNA could have played vital role in the origins life. advent any life requires synthesis its monomers. Here we...
The anthrax lethal toxin neutralization assay (TNA) will likely be used to correlate the protection offered by new anthrax vaccines in animal models to the immunogenicity that will be provided in humans. TNA data are being generated in several different laboratories to measure the immune responses in rabbits, nonhuman primates, and humans. In order to compare data among species and laboratories...
The creation of pathways toward a societal transition to clean energy requires the engagement multiple stakeholders with different and sometimes conflicting interests. In this connection, stakeholder analysis (SA) offers technique for identifying, assessing structuring needs, interests concerns related within context sustainability. This article aims present findings from qualitative (QSA) by u...
This was a randomized, placebo-controlled, Phase I/II study conducted in a Japanese cohort to assess the safety and immunogenicity of Clostridium difficile vaccine (the same formulation as that used in the ongoing global Phase III study). Healthy Japanese adults aged 40-75 years were randomized to receive either C. difficile vaccine (N = 67) or placebo (N = 34) by intramuscular injection on Day...
A 3-dose (0, 1, and 6 months) intramuscular (3-IM) priming series of a human dose (HuAVA) and dilutions of up to 1:10 of anthrax vaccine adsorbed (AVA) provided statistically significant levels of protection (60 to 100%) against inhalation anthrax for up to 4 years in rhesus macaques. Serum anti-protective antigen (anti-PA) IgG and lethal toxin neutralization activity (TNA) were detectable foll...
In Multiple Sclerosis (MS) the relationship between disease process in normal-appearing white matter (NAWM) and the development of white matter lesions is not well understood. In this study we used single voxel proton 'Quantitative Magnetic Resonance Spectroscopy' (qMRS) to characterize the NAWM and thalamus both in atypical 'Clinically Definite MS' (CDMS) patients, MRI(neg) (N = 15) with very ...
Behavioral observations as a matrix of probabilistic changes of postures and acts are multiple measurements that could introduce variability to statistical analysis. We propose the multimetric statistical algorithm that supplements the linear analysis of variance by pair correlation, factor and discriminant function analyses. Although these methods were utilized mostly in behavioral studies, th...
Both instrumental data analyses and coupled ocean-atmosphere models indicate that Atlantic meridional overturning circulation (AMOC) variability is tightly linked to abrupt tropical North Atlantic (TNA) climate change through both atmospheric and oceanic processes. Although a slowdown of AMOC results in an atmospheric-induced surface cooling in the entire TNA, the subsurface experiences an even...
Tonalli A (TnaA) is a Drosophila melanogaster protein with an XSPRING domain. The XSPRING domain harbors an SP-RING zinc-finger, which is characteristic of proteins with SUMO E3 ligase activity. TnaA is required for homeotic gene expression and is presumably involved in the SUMOylation pathway. Here we analyzed some aspects of the TnaA location in embryo and larval stages and its genetic and bi...
BACKGROUND Screw fixation is a typical technique for isolated talonavicular arthrodesis (TNA), however, no consensus has been reached on how to select most suitable inserted position and direction. The study aimed to present a new fixation technique and to evaluate the clinical outcome of individual headless compression screws (HCSs) applied with three-dimensional (3D) image processing technolo...
