Conclusions: Infertility counseling in the early days of marriage and a spermiogram performed at that time could be beneficial for the newly-wed couples even if they do not want a child at the time. To perform a spermiogram as a screening test in all newlywed men should be discussed. Copyright (C) 2011 S. Karger AG, Basel”
“Objectives. This study aimed to assess the prevalence of 3-rooted mandibular first molars among a Shanghai Chinese population by using periapical radiographs.
Methods. A total of 510 patients possessing both mandibular first molars were selected. The radiographs of these cases were evaluated under optimal conditions using double magnifying glasses.
The incidence of 3-rooted mandibular first molars and the correlation between occurrences in males and females and between Q-VD-Oph concentration the left and right sides were recorded and analyzed. A total of 1020 mandibular first molars were evaluated.
Results. A total of 165 patients were found to have a selleck kinase inhibitor 3-rooted mandibular first molar: 92 males and 73 females (P = .106). The overall incidence of patients with 3-rooted mandibular
first molars was 32.35%. Of all the patients with 3-rooted molars, 67.27% (111/165) of cases occurred bilaterally. The incidence of teeth showing an extra root was 27.06%. The occurrence of such permanent 3-rooted mandibular first molars also did not differ significantly between the right side (n = 142, 13.92%) and the left side (n = 134, 13.14%; P = .573).
Conclusions. The prevalence and bilateral incidence of 3-rooted mandibular first molars among the Shanghai Chinese population was high and such variation varied among Chinese populations living in different areas. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2010;110:e98-e101)”
“The influence of B-site nonmagnetic substitution on the
spiral spin ordering in multiferroic manganites is investigated by Monte selleck chemicals llc Carlo simulation within the framework of classical Heisenberg model. It is revealed that the nonmagnetic substitution significantly suppressed the multiferroic phase transitions, consistent with experimental results. The boundary between ab-cycloidal phase and bc-cycloidal phase in the temperature-substitution phase diagram becomes faint gradually with increasing substitution level. A coexistence of two cycloidal spin phases is identified when the substitution level surpassed a threshold. The physical origin for the two-phase coexistence induced by the nonmagnetic B-site substitution is discussed. (C) 2011 American Institute of Physics. [doi:10.1063/1.3594711]“
“WT1 (Wilms’ tumor gene 1) overexpression is implicated in the prognosis of acute leukemia. The purpose of this study was to investigate WT1 expression and its clinical implication in childhood acute leukemia (AL) in Chinese population. Bone marrow specimen from 200 children at different stages of acute leukemia and from 21 children without leukemia were studied.
