Question: Question: Are findings in the distal colorectum associated with proximal advanced serrated lesions?
Answer: The findings at flexible sigmoidoscopy that traditionally serve as indications for colonoscopy (conventional adenomas) are likely to be ineffective for detection of proximal ASL. This finding, plus the observation that most patients with proximal ASL have no distal polyps, favors screening colonoscopy over sigmoidoscopy, especially in the elderly. The observation that non-advanced distal SSA/Ps are associated with any proximal SSA/P warrants further study.

Answer: no


Question: Question: Is allocentric but not egocentric orientation impaired during normal aging : an ERP study?
Answer: These results suggest that elderly individuals present with deficits when spatial orientation relies on allocentric representation, and are associated with age-related deficits in spatial attention.

Answer: yes


Question: Question: Does feeding butter with elevated content of trans-10 , cis-12 conjugated linoleic acid to lean rats impair glucose tolerance or muscle insulin response?
Answer: This study suggests that increasing the consumption of a naturally enriched CLAt10,c12 source, at least in rats, has minimal impact on whole body glucose tolerance or muscle specific insulin response.

Answer:
no
