Researchers have several theories about what's behind this deterioration, but most suspect that aging causes major cell loss in a tiny region in the front of the brain that leads to a drop in the production of a neurotransmitter called acetylcholine. Acetylcholine is vital to learning and memory...
medium and high multifractal genomic context. For example, the ZEB2 protein involved in a chemical signaling pathway regulates early growth and development and obeys a pre-determinate genetic program. In addition, these genes have a high structural inhomogeneity and many irregular characteristics. Similar...
A major goal of genotype–phenotype databases is to provide assistance in assigning pathogenicity to genetic variants. As the focus shifts from the investigation of single genes by Sanger sequencing towards the determination of variants in tens, hundreds or thousands of genes or even the entire geno...
Yoshida was soon to make many of the major advances in the molecular biology of HTLV-1 but this is another story. The second meeting of considerable importance was in London chaired by the late hematologist Sir John Dacie and attended by Dacie, Drs. Daniel Catovsky, Robin Weiss, Mel ...

[Ardekani et al.,2012]. Written informed consent was obtained from participants or from a parent or guardian if the participant was a minor; all minors provided written assent. Exclusion criteria included any history of a DSM-IV axis I major mood or psychotic disorder as assessed by ...
The gROADS data do not include all minor roads, and therefore should be viewed as a map of the major roadways. We mapped the direct and indirect influence of roads by assigning an pressure score of 8 for 0.5 km out for either side of roads, and access pressures were awarded a score ...
32 Bmpr1b is the major transducer of BMP signals in early limb mesenchymal condensations.33 On ligand binding, heterotetrameric formation of BMP type-1 and BMP type-2 receptors occurs at the cell surface. This event triggers the intracellular transphosphorylation of the BMP type-1 receptor, ...
