Is atCTF7 required for establishment of sister chromatid cohesion and association of cohesin with chromatin during meiosis in Arabidopsis?
We find that AtCTF7 is essential for sister chromatid cohesion during meiosis in Arabidopsis and is required for association of cohesin with chromatin in prophase of meiosis.
We no longer routinely perform hepatic IOUS when evaluating patients with pancreatic adenocarcinoma for pancreaticoduodenectomy. When a preoperative study indicates possible hepatic involvement, IOUS can confirm the presence or absence of liver metastases.
