The aim of this study was to develop population-specific regression equations for age estimation by investigating the correlation between chronological age and pulp–tooth volume ratios in three typ...

Since the associations of fermented dairy foods intake with risk of cardiovascular diseases (CVD) remained inconsistent, we carried out this meta-analysis on all published cohort studies to estimate the overall effect. We searched the PubMed and CNKI (China National Knowledge Infrastructure) databases for all articles within a range of published years from 1980 to 2018 on the association between fermented dairy foods intake and CVD risk. Finally, 10 studies met the inclusion criteria for this study, with 385,122 participants, 1,392 Myocardial infarction, 4,490 coronary heart disease (CHD), 7,078 stroke, and 51,707 uncategorized CVD cases. Overall, statistical evidence of significantly decreased CVD risk was found to be associated with fermented dairy foods intake (OR = 0.83, 95% CI = 0.76-0.91). In subgroup analysis, cheese and yogurt consumptions were associated with decreased CVD risk (OR = 0.87, 95% CI = 0.80-0.94 for cheese and OR = 0. 78, 95% CI = 0.67-0.89 for yogurt). Our meta-analysis indicated that fermented dairy foods intake was associated with decreased CVD risk.

Previous studies have revealed that the sternum can provide a method for assessing sex in diverse population groups. In the current study, sternal measurements were recorded from three-dimensional multidetector-computed tomographic images of 255 individuals (112 females and 143 males) in Western China. Results demonstrated that the difference between male and female mean values for all linear dimensions and manubrium index was highly significant. The stepwise analysis of four linear sterna dimensions and manubrium index, in which the sternum index, total length and manubrium width were selected, yielded a sex classification accuracy rate of 81.6% and a sex bias of 2.6%. Furthermore, multivariate discriminant function equations incorporating dimensions of the manubrium and individual sternal dimensions, such as the total length of the sternum and the sternum body, may also be of value in the estimation of sex. The results of the present study with osteometric equations provide an effective method for asses...

Age estimation in living individuals is an area of increasing importance for both radiology and forensic medicine. Owing to a relatively late completion of maturation, the ischial tuberosity can offer a valuable alternative for assessing 18 years of age. However, the ossification of the ischial tuberosity has rarely been investigated with respect to forensic requirements. The aim of the study was to clarify how strong the chronological age relates to the ossification of the ischial tuberosity in the West China Han group. Our results indicated that the ischial tuberosity ossification appears to begin from 15.34 to 16.17 years for males, and from 14.39 to 15.64 years for females. The apophyseal cartilage begins to ossify from 18.50 to 19.17 years for males, and 18.73 to 19.44 years for females, and has fully ossified from 22.93 to 23.30 years for males, and 23.62 to 24.07 years for females. The present study offers a valuable alternative for age estimation.
