Most members of the Streptococcus mutans group of microorganisms specify a major cell surface-associated protein, SpaA, that is defined by its antigenic properties. The region of the spaA gene from Streptococcus sobrinus 6715 encoding the immunodominant determinant of the major antigenic component (antigen I) of the SpaA protein has recently been characterized. This study examined whether recog...
BACKGROUND/AIM The optimal treatment of liver metastases from gastric cancer (LMGC) remains uncertain. We retrospectively compared surgical treatment with chemotherapy alone and identified prognostic determinants. PATIENTS AND METHODS We reviewed the records of 50 consecutive patients with LMGC: 25 patients with gastrectomy plus hepatic resection (group A), 13 patients with palliative gastrec...
The chemical composition and serological properties of endotoxin prepared from gonococci by extraction with aqueous ether have been described in previous reports (Maeland, 1969b, 1969c). Aqueous ether endotoxin contains one antigenic determinant of carbohydrate nature (determinant a) and another antigenic determinant of protein nature (determinant b) (Maeland, 1968, 1969a). A serological test s...
two groups of students were assigned as experimental and control ones, and were given instruction on directed reading-thinking activities and after some treatment, they were post-tested. although the initial pre-test did not show any significant differences, the final post-test result revealed that the cooperative reading comprehension helped the experimental group. the cooperative students’...
We calculate the lower Controlled Algebraic K-theory of any finitely generated infinite subgroup of SL(3, Z), the group of 3 × 3 integral matrices of determinant 1.
the present study investigated the effect of the two vocabulary teaching techniques in est, namely the use of translation and the use of visual aids as two separate vocabulary teaching techniques. to answer the question of the study, a pretest (michigan test) was administered to the 58 randomly selected est students at khajeh nasiredin tusi university, faculty of mechanics. after the homogeneit...
