Mutations in the spermine synthase gene are reported to cause Snyder-Robinson syndrome, an X linked mental retardation disorder condition accompanied by thin habitus and skeletal defects such as osteoporosis (Cason et al. 2003).
On a visit to the Goldcorp mine, THP documented symptoms from mass poisoning in nearby villages that included lesions, hair loss, and mental retardation; the conditions being most pronounced in infants and children.
If you look up idiot, imbacile, dumb, etc.. they are all derogatory terms for someone with mental retardation, so this condition has been plagued with the condition used as derogatory term for quite some time.
Five diagnostic groups were analysed: anxiety-depression/neuroses, personality disorders, substance-related disorders, mental retardation and neurological conditions.
However, besides their rather selfish role in genetic addiction these factors have been proposed to mediate growth retardation under stress conditions [ 32].
However, at high MOI (≥1), cell populations transduced by MOV-scT6cA displayed strong growth retardation under inducing conditions (Additional file 3: Figure S3), suggesting massive accumulation of M2-transactivator to levels that caused squelching [ 23, 34, 35].
In the case of the ami-7.1 line, the relative response to ABA was similar to that of the control, which might be due to the severe growth retardation under control conditions.
OsDREB1A and OsDREB1B are induced by cold stress, and constitutive overexpression of these genes in transgenic Arabidopsis and rice leads to induction of stress-responsive genes, increased high cold and salt tolerance, and growth retardation under normal conditions [ 8, 9].
The experimental results showed that, in all conditions, overload retardation occurred and the retarded propagation distances of crack were longer than the plastic zone size caused by overload at the crack tip.
The problem is that people with mental retardation, because of their condition and diminished intellectual capacity, commonly exhibit symptoms similar to those seen among people who have impulse control, anxiety or attention deficit disorders.
