Lifestyle factors of people with exceptional longevity.

Objectives: To assess lifestyle factors including physical activity, smoking, alcohol consumption, and dietary habits in men and women with exceptional longevity.

Design: Retrospective cohort study.

Setting: A cohort of community-dwelling Ashkenazi Jewish individuals with exceptional longevity defined as survival and living independently at age 95 and older.

Myosin VI is required for structural integrity of the apical surface of sensory hair cells in zebrafish.

Unconventional myosins have been associated with hearing loss in humans, mice, and zebrafish. Mutations in myosin VI cause both recessive and dominant forms of nonsyndromic deafness in humans and deafness in Snell's waltzer mice associated with abnormal fusion of hair cell stereocilia. Although myosin VI has been implicated in diverse cellular processes such as vesicle trafficking and epithelial morphogenesis, the role of this protein in the sensory hair cells remains unclear.

Multiple mutations of MYO1A, a cochlear-expressed gene, in sensorineural hearing loss.

Myosin I isozymes have been implicated in various motile processes, including organelle translocation, ion-channel gating, and cytoskeleton reorganization. Unconventional myosins were among the first family of proteins found to be associated with hearing loss in both humans and mice. Here, we report the identification of a nonsense mutation, of a trinucleotide insertion leading to an addition of an amino acid, and of six missense mutations in MYO1A cDNA sequence in a group of hearing-impaired patients from Italy.

The transplantation of organs, which at first sight appears to be just a technical medical procedure, is, first and foremost a sociocultural action that gives expression to existential perceptions. In Israeli society, as in most western societies the donation of the body or parts of it, is interpreted as possible at a societal level, and not as a gift from one individual to another. The medical achievement inherent in organ transplantation brings forward the relationship between the body, death and society.
