Computed tomographic (CT) cystography has been advocated in lieu of conventional cystography in the initial work-up of patients with suspected urinary bladder trauma. CT cystography was applied to a classification scheme for bladder injury based on the degree of wall injury and anatomic location and demonstrated characteristic imaging features for each type of injury. In bladder contusion (type 1), findings are normal.
The use of Fuji films is simple but their manipulation and result interpretation seem to be difficult in the framework of medical research. The reliability and reproducibility of Fuji films have been proved by many previous studies. This study was undertaken to know precisely the articular zones of the elbow and to determine the compressive stress these areas undergo during different activities, in order to assess the importance of different articular contact areas.
Iron is essential for organisms. It is mainly utilized in mitochondria for biosynthesis of iron-sulfur clusters, hemes and other cofactors. Mitoferrin 1 and mitoferrin 2, two homologues proteins belonging to the mitochondrial solute carrier family, are required for iron delivery into mitochondria. Mitoferrin 1 is highly expressed in developing erythrocytes which consume a large amount of iron during hemoglobinization. Mitoferrin 2 is ubiquitously expressed, whose functions are less known.

OBJECTIVE: A systematic genome survey was initiated to identify loci that affect the likelihood of reaching age 90 with preserved cognition. This communication describes the clinical characterization and comparison of the experimental groups, validation of the experimental method, and results for the Y chromosome. METHODS: The genome survey was conducted at 10 cM resolution for simple sequence tandem repeat polymorphisms (SSTRPs) that identify genes for successful aging by virtue of linkage disequilibrium.
The exceptional longevity of centenarians is due in part to inherited genetic factors, as deduced from data that show that first degree relatives of centenarians live longer and have reduced overall mortality. In recent years, a number of groups have performed genetic association studies on long-living individuals (LLI) and young controls to identify alleles that are either positively or negatively selected in the centenarian population as consequence of a demographic pressure. Many of the reported studies have shown genetic loci associated with longevity.

The single nucleotide polymorphism, rs2866164, in the MTP gene, has been associated with human longevity but has not been validated by subsequent longevity studies. Using our population of Ashkenazi Jews, we find that the MTP CC genotype is significantly overrepresented in centenarians and their offspring, as compared with controls (p < .05). However, when we examined MTP CC genotype frequency pattern with aging, we observed a monotonic decline between ages 55-85 years followed by a dramatic enrichment after age 90 years, forming a U-shape pattern (p < .05).
Neuroimaging studies have become increasingly multimodal in recent years, with researchers typically acquiring several different types of MRI data and processing them along separate pipelines that provide a set of complementary windows into each subject's brain. However, few attempts have been made to integrate the various modalities in the same analysis. Linked ICA is a robust data fusion model that takes multi-modal data and characterizes inter-subject variability in terms of a set of multi-modal components.
BACKGROUND: Assessing a combination of modifiable lifestyle practices may be a practical tool to modify patients' health behavior in counseling. Therefore, we developed a chronic disease risk index (CDRI) and investigated its relation with chronic disease in a multiethnic cohort. METHODS: A total of 15,693 men and 16,007 women in Hawaii who reported their diet and other lifestyle behaviors between 1975 and 1980 were followed until 1994.
To elucidate the impact of diet on age-at-death determinations based on molar attrition a comparison was made between the established rate of attrition in three populations; a pre-mediaeval (British), a late mediaeval (Dutch) and a 17-18th century (Dutch) (western European). It appeared that the rate decreased dramatically during the overall time span and that this change was probably diet related and owing to the coarseness of foodstuffs.
OBJECTIVE: To explore the relationship between self-reported weight and height to actual weight and height in a cross-sectional representative sample of school students in Jeddah City, Kingdom of Saudi Arabia and its relation to selected socio-economic and socio-demographic factors. Also to evaluate the validity of self-reported weight and height measurements. METHODS: Data was collected from a sample of Saudi school students in Jeddah City, KSA from 42 boys' schools and 42 girls' schools during the month of April 2000.
