Chlorinated Hydrocarbon Residues (PCB and DDT) in Human Liver, Adipose Tissue and Brain in Finland
2009
In this work the concentration of chlorinated hydrocarbons (PCB and DDT) was analyzed from 73 autopsy samples. Half of the material came from the coastal area of the Gulf of Bothnia and the other half from Central Finland. The correlation of the concentration of the drug to age, sex and the locality was studied as well as the occupation of the dead subjects.
The Particular Story of Italians' Relation with Alcohol: Trends in Individuals' Consumption by Age and Beverage Type.
2015
Aims In Italy, sales data show a dramatic fall in alcohol consumption between 1970 and 2010. The aim of our study is to provide updated information on trends, prevalence and determinants of alcohol drinking in Italy, using individual-level data. Methods Seven nationally representative cross-sectional surveys were conducted in Italy between 2006 and 2014, on a total sample of 21,416 participants aged ≥15 years, with available information on weekly consumption of wine, beer and spirits. Results Per capita alcohol consumption decreased by 23% between 2006 and 2014 (from 5.6 to 4.4 drinks/week), due to the fall in wine drinking. Overall, the prevalence of alcohol drinkers was 61.6%. Individuals…
Pattern analysis of human cutaneous mast cell populations by total body surface mapping.
2003
SummaryBackground Mast cells (MCs), critical effector cells in allergic inflammation and innate immunity to bacteria, are located in large numbers in tissues that interface the external environment, including the skin. However, little is known about the distribution and numbers of human skin MCs. Objectives To assess the influence of age, sex and skin region on size and spatial distribution of MC populations in normal human skin. Methods Biopsies of healthy skin were obtained from 150 male and female individuals (age range 10–86 years). MCs were quantified and mapped planimetrically by histomorphometry in 15 anatomical sites (abdomen, thorax, lower and upper back, lower and upper arm, lower…
Gonial angle growth patterns according to age and gender
2017
Currently there are controversial results about gender and age differences in human gonial angle values. In this context we aimed to ascertain the gender and age differences in the gonial angle values of young Caucasian Mediterranean subjects. We tested the hypothesis of a relation between the gonial angle values and the gender and age of the subjects by means of a prospective study involving 266 subjects. Panoramic radiographs (Cranex Novus®, XMIND Novus® Soredex, France) were carried out in order to measure the gonial angle values. We found significant differences between females and males in the subgroups aged ≤10years old (128.6±3.4 vs 126.8±4.5, p=0.017), 16-20 years old (119.1±5.6 vs …
A method of measuring the apical base
1996
SUMMARY The maxillary and mandibular apical base areas were measured, using a gnathograph, on the study casts of 156 adults and children representing Class II division 1, Class II division 2 and Class III malocclusions. There were significant differences between the groups at each age. The maxillary apical base areas tended to be smaller for the adults than for the children in all three occlusal classes. By contrast, the mandibular apical base areas tended to be larger for the adults than for the children, except in Class II division 1 malocclusion. Following a logarithmic transformation to stabilize the variance, regression lines were fitted to relate the size of the maxillary and mandibul…
Reliability and validity of the Digigraph 100 in orthodontic diagnosis.
2001
Cephalometric analyses of lateral cephalograms allow important statements to be made on diagnosis and treatment planning. Such radiographs should, however, be taken with a considerable reduction in radiation exposure. With the Digigraph 100 (Dolphin Imaging Systems Inc., USA) a cephalometric technique based on distance measurements of emitted sonic signals is now available. This study was aimed at determining the degree to which this procedure can cope with the requirements of reliability and validity in the field of orthodontics. For this purpose 50 volunteers were examined by conventional cephalometry with manual tracing of lateral cephalograms as well as by sonic cephalometry, with Jarab…
Linking planning performance and gray matter density in mid-dorsolateral prefrontal cortex: Moderating effects of age and sex
2012
Abstract Planning of behavior relies on the integrity of the mid-dorsolateral prefrontal cortex (mid-dlPFC). Yet, only indirect evidence exists on the association of protracted maturation of dlPFC and continuing gains in planning performance post adolescence. Here, gray matter density of mid-dlPFC in young, healthy adults (18–32 years) was regressed onto performance on the Tower of London planning task while accounting for moderating effects of age and sex on this interrelation. Multiple regression analysis revealed an association of planning performance and mid-dlPFC gray matter density that was especially strong in late adolescence and early twenties. As expected, for males better plannin…
Calcification patterns of the internal elastic membrane
1969
Calcification patterns of the internal elastic membrane of the main pelvic arteries, lower limb arteries, brachial, splenic and renal arteries were demonstrated grossly by a modified von Kossa technique. In the elastic segment in the common and internal iliac arteries, the membrane calcification appeared as groups of roundish or polygonal incrustations. They were found frequently in newborns, and were always present in infants of more than three months, as well as in adults. In the muscular arteries, the calcified parts of the internal elastic membrane appeared grossly as pairs of bands (“calcific bands”) along the edges of the pre-existing gaps in this membrane. When calcification was pron…
Influential Periods in Longitudinal Clinical Cardiovascular Health Scores
2021
Abstract The prevalence of ideal cardiovascular health (CVH) among adults in the United States is low and decreases with age. Our objective was to identify specific age windows when the loss of CVH accelerates, to ascertain preventive opportunities for intervention. Data were pooled from 5 longitudinal cohorts (Project Heartbeat!, Cardiovascular Risk in Young Finns Study, The Bogalusa Heart Study, Coronary Artery Risk Development in Young Adults, Special Turku Coronary Risk Factor Intervention Project) from the United States and Finland from 1973 to 2012. Individuals with clinical CVH factors (i.e., body mass index, blood pressure, cholesterol, blood glucose) measured from ages 8 to 55 year…
Management of primary ameloblastoma of the jaw: a 15 years' experience.
2012
AIM: The aim of this retrospective study was to describe our 15-year experience in the management of primary ameloblastoma of the jaw. METHODS: We investigated 26 patients who had undergone surgical treatment for a single lesion, comprising six lesions of the maxillary bone and 20 tumors of the mandible: 73% had a radiolucent multilocular lesion; 23% a unicystic lesion; and 4% had an extraosseous form of the tumor. The smaller lesions (diameter <3 cm) were treated by conservative approaches; the larger lesions required radical surgical resection. Two groups were created according to whether the patients had received conservative or aggressive surgery. RESULTS: The recurrence rate was estima…
