Is echogenic endometrial fluid collection in postmenopausal women a significant risk factor for disease?
Postmenopausal women with endometrial fluid collection on sonography should undergo endometrial sampling if the endometrial lining is thicker than 3 mm or the endometrial fluid is echogenic. If the lining is 3 mm or less and the endometrial fluid is clear, endometrial sampling is not necessary, but we recommend endocervical sampling to rule out endocervical cancer.
VH genes encoding rat anti-pig xenoantibodies are expressed in germline configuration and share structural similarities, including identical amino acids in key antigenic contact sites that define antibody canonical structural groups, with antibodies to infectious agents.
