Leber congenital amaurosis (LCA) is a rare inherited eye disease that appears at birth or in the first few months of life. [2]It affects about 1 in 40,000 newborns. [1] LCA was first described by Theodor Leber in the 19th century.
Life cycle assessment (LCA) is sometimes referred to synonymously as life cycle analysis in the scholarly and agency report literatures. [7] [1] [8] Also, due to the general nature of an LCA study of examining the life cycle impacts from raw material extraction (cradle) through disposal (grave), it is sometimes referred to as "cradle-to-grave analysis".
Avoided burden (also known as the 0:100 method or end-of-life method) is an allocation approach used in life-cycle assessment (LCA) to assess the environmental impacts of recycled and reused materials, components, products, or buildings. While the approach has been adapted to fit a variety of LCA goals, it generally considers products with ...
Lithocholic acid, also known as 3α-hydroxy-5β-cholan-24-oic acid or LCA, is a bile acid that acts as a detergent to solubilize fats for absorption. Bacterial action in the colon produces LCA from chenodeoxycholic acid by reduction of the hydroxyl functional group at carbon-7 in the "B" ring of the steroid framework.
It is compliant with the approach for quantifying spend-based impacts defined in the Greenhouse Gas Protocol Corporate Value Chain Accounting and Reporting Standard. The tool utilizes the Comprehensive Environmental Data Archive (CEDA), [4] a peer-reviewed EIO-LCA database with a base year of 2014. CEDA represents 389 industrial sectors, the ...
A most recent common ancestor (MRCA), also known as a last common ancestor (LCA), is the most recent individual from which all organisms of a set are descended. The term is also used in reference to the ancestry of groups of genes ( haplotypes ) rather than organisms.
In this tree, the lowest common ancestor of the nodes x and y is marked in dark green. Other common ancestors are shown in light green. In graph theory and computer science, the lowest common ancestor (LCA) (also called least common ancestor) of two nodes v and w in a tree or directed acyclic graph (DAG) T is the lowest (i.e. deepest) node that has both v and w as descendants, where we define ...
8-Oxoguanine (8-hydroxyguanine, 8-oxo-Gua, or OH 8 Gua) is one of the most common DNA lesions resulting from reactive oxygen species [2] modifying guanine, and can result in a mismatched pairing with adenine resulting in G to T and C to A substitutions in the genome. [3] In humans, it is primarily repaired by DNA glycosylase OGG1.
