Some writers suggest that such cognitive alterations are a necessary prelude or accompaniment to successfully eliminating or at least diminishing the force of the reactive attitudes typical of having been wronged.
Our results therefore show that VHL gene alterations are neither necessary nor sufficient for angptl4 mRNA expression in human tumors.
Moreover, in HPV-infected patients, the majority of HPV-associated lesions regress spontaneously (Melnikow et al, 1998), indicating that additional genomic alterations are also necessary for transformation of cervical epithelial cells and progression of cervical cancer.
DNA alterations are necessary for the evolution by natural selection 7. DNA alterations are necessary for speciation 8. DNA alterations are needed to cause species diversity.
One model for examining the myriad of genetic and epigenetic alterations necessary for invasion was created in our laboratory via serial selection through Matrigel® in a modified Boyden chamber [ 16].
However, Ms. Fink said, it generally is necessary to get permits from the Department of Buildings if any construction or alterations are necessary to convert a home into a community facility.
Exactly what alterations are necessary on all of those cars is unknown, and independent engineers said it could be extremely difficult to repair the emissions systems without harming engine efficiency and performance.
A mouse model of human HCC with inducible expression of MYC in adult liver cells has shown that overexpression of MYC is sufficient to initiate HCC development; however, these tumors develop with a prolonged latency, suggesting that other genetic alterations are necessary to generate HCC, including mutations in the p53 pathway [32], [37], [38], [39], [40].
However, additional genetic alterations are necessary for overt transformation from an initial preleukemic clone [ 9, 10].
No dosage alterations are necessary for PK reasons when treating elderly people with buprenorphine transdermal patches.
