BACKGROUND Inability to intubate and ventilate patients with respiratory failure is associated with significant morbidity and mortality. A patient is considered to have a difficult airway if an anesthesiologist or other health care provider experienced in airway management is unable to ventilate the patient's lungs using bag-mask ventilation and/or is unable to intubate the trachea using direct...

A study was conducted to assess the durable resistance in a near isogenic line of spring wheat (Triticum aestivalis L.), possessing resistance gene Yr-18 to some isolates (race specific resistance) of stripe rust (Puccinia striiformis f. sp. tritici), namely Thatcher Yr-18 and durable resistance of an cultivar of spring wheat to all isolates of stripe rust (race non- specific resistance), namel...

Since the early 1960s, the Chesapeake Bay striped bass population has undergone a large cycle of abundance, recovering to record levels during the 1990s. Changes in age structure over this period were examined to determine contributions of old females (>13 yr) to the recovery. In 1992, in a sample of large female striped bass, 10 yr of absent year classes (1972–1981) were observed corresponding...

Major fluxes of sulphur and dissolved inorganic nitrogen were estimated in Central European mountain ecosystems of the Bohemian Forest (forest lakes) and Tatra Mountains (alpine lakes) over the industrial period. Sulphur outputs from these ecosystems were comparable to inputs during a period of relatively stable atmospheric deposition (10-35 mmol m-2 yr-1) around the 1930s. Atmospheric inputs o...

Stathokostas, Liza, Shanthi Jacob-Johnson, Robert J. Petrella, and Donald H. Paterson. Longitudinal changes in aerobic power in older men and women. J Appl Physiol 97: 784–789, 2004. First published March 26, 2004; 10.1152/japplphysiol.00447.2003.—The purpose of this study was to describe the longitudinal (10 yr) decline in aerobic power [maximal O2 uptake (V̇O2 max)] and anaerobic threshold [ve...

The purpose of this study was to describe the longitudinal (10 yr) decline in aerobic power [maximal O(2) uptake (Vo(2 max))] and anaerobic threshold [ventilatory threshold (T(Ve))] of older adults living independently in the community. Ten years after initial testing, 62 subjects (34 men, mean age 73.5 +/- 6.4 yr; 28 women, 72.1 +/- 5.3 yr) achieved Vo(2 max) criteria during treadmill walking ...

The purpose of the study was to determine the effect of vitamin D supplementation on bone turnover and bone loss in elderly women. Three hundred forty-eight women, ages 70 yr and older, were randomized to receive 400 IU vitamin D3 per day (n = 177) or placebo (n = 171), double-blind, for a period of 2 yr. Main outcome measures were bone mineral density of both hips (femoral neck and trochanter)...

A retrospective study was conducted of burn patients admitted to the military hospital in Rabat, Morocco, in the 6-yr period from 2004 to 2009. This is the first multivariate study to be performed in Morocco. The epidemiological data from the 291 patients hospitalized were collected and studied. The type of burn was indicated in 284 of the patients: 94% of the injuries were thermal burns, 4% we...

BACKGROUND High rates of sub-fertility and adverse pregnancy outcomes were seen after age 40. In contrast to oogenesis, spermatogenesis continues in elderly men. OBJECTIVE To retrospectively study the impact of aging on semen parameters in male partners of infertile couples in the rural area of developing country over 10 years and to find out whether aging affects male factor fertility and va...

Acquired perforating dermatosis (APD) is a skin disorder occurring in the patients with chronic renal failure (CRF), diabetes mellitus (DM) or both. The purpose of this study was to clarify the clinical and histopathological features of APD, and evaluate role of scratching in the pathogenesis of APD. Twelve patients with APD associated with CRF and DM were enrolled in the study. In six patients...
