The Graded Naming Test and sociocultural differences: Researchers often use z tests to compare their samples to known population norms. The Graded Naming Test (GNT) asks respondents to name objects in a set of 30 black-and-white drawings. The test, often used to detect brain damage, starts with easy words like kangaroo and gets progressively more difficult, ending with words like se
Determining genotypes in autosomal dominant pedigrees Pedigree 2 from Part A is
Determining genotypes in autosomal dominant pedigrees Pedigree 2 from Part A is shown below. Recall that this pedigree shows the inheritance of a rare, autosomal dominant condition. Fill in the genotypes for the indicated individuals in the pedigree by dragging the best label to the appropriate location. Labels can be used once, more than once, or not at all.
Can D-Aspartic Acid be used in in place of L-Aspartic Acid, with regard to the attached study
The study below uses L-aspartic acid in combination with other amino acids to achieve a desired outcome. I was wondering if D-aspartic acid could be used instead, and if combining it with the other amino acids would help it cross the BBB as well as have similar NMDA-agonist effects, achieving the same result (glutamateric activation).
