In an attempt to expand the donor pool, transplant programs are now accepting older donors as well as donors from more remote areas. The purpose of this ...

The importance of reversible airflow obstruction to the prognosis of asthma and chronic obstructive pulmonary disease (COPD) is not clear. We tested the hypothesis that reversibility to corticosteroid and bronchodilator is not an independent predictor of prognosis, but merely reflects a component of the maximal attainable lung function, which is ...

Forty-two yearling males from seven European beef breeds were used to study breed type and ageing time effects on meat sensory quality. Breeds were grouped according to their double muscled condition (DM), dual-purpose condition (Brown Swiss, BS), fast growth rate (FG) and rustic characteristics (RT). Vacuum packaged loin chops were ...

The probability to survive to the age x universally increases with the mean lifespan x(bar). For species as remote as humans and flies, for a given x the rate of its evolution with x is constant, except for the narrow vicinity of a certain x(bar) = x* (which equals 75 ...

Females with cystic fibrosis have significantly higher mortality than males from age 1 to age 20, resulting in an approximate four-year difference in median survival age. Survival is associated with a lack of colonization by pathogenic bacteria, as well as better pulmonary function, weight for height, and fitness. This statistically ...

Ageing is the decline in survival probability and fertility later in adult life. It can evolve through mutation accumulation and pleiotropy. Artificial selection by age at reproduction is a useful method for detecting the effects of pleiotropy, and for producing lines that differ in their rate of ageing for further ...

Milk, fat, and protein yields were adjusted to 305 d. Days open was truncated to 305 d, and the number of services was ...

Much of the increase in cancer incidence is explained by the increasing number of elderly in the population. Even at a relatively advanced age, many have a life expectancy in the range of, or longer than, the expected 5- or 10-year survival of the malignant disease diagnosed. There are some ...

OBJECTIVE: To identify the age at which screening for syphilis could be ceased in Kimberley Aboriginal people who had remained seronegative and whether this age was the same for people with and without a past history of gonorrhea. DESIGN: Retrospective cohort study. SETTING: The Kimberley region in the far north ...

BACKGROUND: The standard approach for survival analysis of the elderly population is to define the survival time as the elapsed time from entry into the study until death, and to adjust by age using stratification and regression procedures. However, the interest is in the study of the aging process and ...

OBJECTIVE: The optimal age for transplantation in children with end-stage renal disease remains controversial. Supported by national data, many centers recommend dialysis until the child reaches a certain minimum age. The authors' policy, however, has been to encourage living donor (LD) transplants for young children, with no minimum age restriction. ...

The necessity of a circadian pacemaker, the suprachiasmatic nuclei (SCN), for survival was evaluated in a population of approximately 65 wild eastern chipmunks, Tamias striatus. The research involved over 3000 h of field-work between May 1995 and October 1997 on a study site at Mountain Lake Biological Station, Virginia. The ...

Tufted capuchins (Cebus apella) were provided with a task that facilitated the use and modification of sticks as probing tools. It was found that subjects aged 10 years or older at initial task exposure were less likely to use tools than were younger subjects. Furthermore, juveniles whose mothers died before ...

Old-age survival has increased substantially since 1950. Death rates decelerate with age for insects, worms, and yeast, as well as humans. This evidence of extended postreproductive survival is puzzling. Three biodemographic insights--concerning the correlation of death rates across age, individual differences in survival chances, and induced alterations in age patterns ...

Three species of flies were examined for chilling tolerance from the end of the pupariation to the onset of adult eclosion for the purpose of determining applicability for cold storage. For the housefly, Musca domestica (Diptera, Muscidae), survival to eclosion was affected by developmental stage/age, length of storage, and storage ...
