BACKGROUND/AIMS: The prevalence of colonic diverticulosis in Korea is increasing in conjunction with the adoption of western dietary pattern, extension of lifespan, and advances in diagnostic modalities. The clinical characteristics of colonic diverticulosis seem to be gradually becoming similar to those of Western societies. Therefore, factors associated with the clinical characteristics of colonic diverticulosis in Korea were investigated.

Sex differences in lifespan exist world-wide, with women outliving men by more than a decade in some countries. The gender gap is not a uniquely human phenomenon; most sexually reproducing species examined show sex differences in patterns of ageing, yet a comprehensive explanation does not exist. Here, we discuss how ageing responds to natural selection on traits that arise as a consequence of sexuality.
Ames dwarf (Prop1 (df/df) ) mice are remarkably long-lived and exhibit many characteristics of delayed aging and extended healthspan. Caloric restriction (CR) has similar effects on healthspan and lifespan, and causes an extension of longevity in Ames dwarf mice. Our study objective was to determine whether Ames dwarfism or CR influence neuromusculoskeletal function in middle-aged (82 ± 12 weeks old) or old (128 ± 14 w.o.) mice.
Data on a study group of 52 maintenance hemodialysis patients cannulated with Quinton-Scribner cannula in a four-year period were analyzed. The average period of dialysis was 11.8 months with either a pumped coil or a pumpless Kiil artificial kidney system. One hundred and forty-five cannulations were performed. The mean arterial cannula survival was 7.8 months and the mean venous cannula survival was 7.2 months. The exceptional longevity of cannula survival occurred despite the high incidence of atherosclerotic changes at operation and the advanced mean age (47 years) of the patients.

Biblical writers generally viewed old age as a reward for righteousness and piety. Consequently, they stressed the belief that the elderly were blessed and that they should be venerated. While life expectancy was usually below forty years, there are exceptional cases on record of individuals--men and women--living to advanced old ages. An analysis of these special few cases and a discussion of extra-Biblical texts shows that other ancient Middle Eastern societies held attitudes toward aging and the aged comparable to those expressed in the Hebrew Bible.
We report the natural history, the clinical, radiological, echocardiographic and hemodynamic pattern of a living sixty-three year old man with tetralogy of Fallot and cyanosis since birth. We discuss the possible circulatory adaptations which allowed exceptional survival up to the seventh decade: it is the sixth case reported in the literature.
This article summarizes recent findings in a case study of exceptional longevity. CM, a resident of San Rafael, California, was 114 years old in August 1996. He is the first properly verified case of a 114-year-old man in human history (although a few women have been known to live longer). Our investigation of CM continues as we attempt to gather additional information about his life, family history, and current condition. Here, we consider only two aspects of this case: its authenticity and its significance in the history of human longevity.
Many years ago, Alex Comfort experimentally refuted Bidder's hypothesis that fish potentially were immortal. Later morphological and physiological studies, together with observations from fish populations in the wild, revealed that fish age in a way similar to that in other vertebrates. More recently, assessments of the age of fish have been revised, and have shown that some species live much longer than was estimated.
