In this study, we explore how a hurricane disturbance influenced carbon allocation for the production of new fine roots. Before and after a hurricane, we measured the age of carbon (time since fixation from the atmosphere) in fine root structural tissues using natural abundance radiocarbon (14C) measured by accelerator mass spectrometry. Roots were sampled from five seasonally dry tropical fore...

Patients with psoriasis have an increased incidence of arthritis. Information on the incidence of psoriatic arthritis (PsA) is sparse. The present study covered those subjects who were entitled under the nationwide sickness insurance scheme to receive specially reimbursed medication for PsA in 5/21 central hospital districts in Finland (population basis ~ 1 million adults) in 1990. A total of 6...

BACKGROUND Vitamin D is a vital lipid-soluble vitamin in the body, helping the growth and development of bones. Vitamin D deficiency in children has several adverse effects. The most important preventative factor is determining the deficiency at an early stage and prescribing vitamin D-containing supplements. OBJECTIVES To investigate the vitamin D status of children younger and older than 2 ...

Lung function tests were performed on apparently healthy, non-smoking male volunteers aged 16-50 years normally staying in Varanasi city area. The volunteers were divided into five groups according to their age (16-19 yr, 20-25 yr, 26-30 yr, 31-35 yr, 40-50 yr). Anthropometric determinants (height and weight) and respiratory performance (vital capacity and peak expiratory flow rate) were record...

From 1975 until 1987, 122 patients without (Group I, mean age 34 yrs) and 20 with pre-existing lung disease (Group II, mean age 66 yrs) were treated for their first spontaneous pneumothorax. Mean follow-up was 5.2 yrs (max. 12.8 yrs). There were 32 chest X-ray verified recurrences, 72% occurring during the first 2 yrs. One, 5 and 10 yr cumulative recurrence freedoms +/- standard error in groups...

The pineal hormone melatonin has some circadian regulatory effects and is assumed to have a close relation with sleep initiation and maintenance. Many previous reports have described age-related decreases in melatonin levels, especially in elderly insomniacs (EIs), which may act as causal or exacerbating factors in sleep disturbances in the elderly. Ten elderly residents with psychophysiologica...
