Montana 1911: A Professor and His Wife Among the Blackfeet: Wilhelmina Maria Uhlenbeck-Melchior's Diary and C.C. Uhlenbeck's Original Blackfoot Texts and a New Series of Blackfoot Texts

In the summertime of 1911, Dutch anthropologist and linguist C. C. Uhlenbeck traveled to Montana to behavior fieldwork one of the southern Piegan Indians. Accompanying him in the course of his three-month remain used to be his spouse, Wilhelmina, who stored a diary in their studies one of the Blackfeet. This diary is reproduced right here in complete, translated for the 1st time from Dutch into English by way of Mary Eggermont-Molenaar.

WS cells are also characterized by genomic instability in the form of variegated translocation mosaicism and extensive deletions. ' WS cells display a defect in the G2-phase decatenation checkpoint which is known to inhibit progression into mitosis until chromatids are correcdy decatenated by topoisomerase II. In WS cells, failure to phosphorylate BRCAl in an ATR-dependent manner in response to decatenation checkpoint activation results in enhanced chromosomal damage and apoptosis. ^ Like BLM, WRNcscn suppress increased homologous and illegitimate recombination in the SGSl mutant.

What is the basis of the reduced amount of TFIIH in TTD cells? In vivo, the ectopic expression of the XPD wild-type protein in XPD mutated TTD cells appeared to be sufficient to restore normal levels of the other TFIIH subunits. This increase was paralleled by the restoration of normal repair activity (Fig. 7). "^^ In vitro evidence further indicates that a mutated TFIIH subunit may affect the stability of the entire complex. ^5 j ^ ^ ^ .
