Previous genetic studies have suggested a history of sub-Saharan African gene flow into some West Eurasian populations after the initial dispersal out of Africa that occurred at least 45,000 years ago. However, there has been no accurate characterization of the proportion of mixture, or of its date. We analyze genome-wide polymorphism data from about 40 West Eurasian groups to show that almost ...

The aim was to determine whether the effects of age, period (from 1987 to 1997), or cohort (birth-cohort) are the most plausible explanations for the variation in dentist utilisation over time in Spain. On the basis of three sequential Spanish National Health Surveys, the trend in the percentage of people visiting the dentist within the previous 3 months was analysed by means of a standard coho...

results out of the 129 elderly participants, aged between 60-87 years (mean: 66.71 ± 6.21), males constituted 58.1% (n = 75) of patients and female were 41.9% (n = 54). normal variations of oral mucosa were observed in 62% (n = 80) of patients, while 44.2% (n = 57) had oral mucosal lesions. normal variations were significantly associated with smoking (or = 1.2), while denture wearers were at hi...

OBJECTIVE To determine the factors contributing to the initiation and propagation of smoking in visitors to a major tertiary health center in Karachi, Pakistan. METHODS Seven major contributing factors to the initiation and propagation of smoking were presented to consenting study participants (n=170) in a questionnaire. Participants were then requested to use their experience and opinion to ...

Age-related changes in temporal order memory have been well documented in older adults; however, little is known about this ability during middle age. We tested healthy young, middle-aged, and older adults on a previously published visuospatial temporal order memory test involving high and low interference conditions. When interference was low, young and middle-aged adults did not differ, but b...

Duking the past year we have had seven cases ?f Bacillus coli bacilluria (which have been pioved to be such by laboratory tests) pass through our hands, varying in degree from an ambulatory type to the most serious illness, which ]n one case terminated fatally. The patients were all females and the age v?.ried from infancy (18 months) through childhood <12 years) to mature middle age. One of th...

Five measures of temporal order judgments were obtained from 261 participants, including 146 elder, 44 middle aged, and 71 young participants. Strong age group differences were observed in all five measures, although the group differences were reduced when letter discriminability was matched for all participants. Significant relations were found between these measures of temporal processing and...

Cardiovascular disease (CVD) mortality and morbidity increases with increasing age, largely as a result of increased lifetime exposure as well as increased prevalence of CVD risk factors. Hospitalization for CVD increases by a factor of over 18× for those aged 85+ years versus those aged <30 years. In spite of this, life expectancy continues to increase, and in Australia for people reaching the...

PURPOSE This study was done to determine the effects of weight management program using self-efficacy in middle-aged obese women. The study also attempted to measure the effects of the program on the weight efficacy lifestyle, body composition, and depression. METHOD The research design of this study was a nonequivalent control group pretest-posttest design. The experimental group consisted o...
