A malathion resistance gene associated with increased life span of the rusty grain beetle, Cryptolestes ferrugineus (Coleoptera: cucujidae)
Article Abstract:
Analysis of the life span of a malathion-resistant strain, a malathion-susceptible strain and two other strains of Cryptolestes ferrugineus, the rusty grain beetle, at 75% relative humidity and 30 degrees Celsius reveals that virgin, malathion-resistant adults possess a longer life span of 37 weeks than virgin, susceptible adults. The life span is a vital factor for these insects, whose reproductive period is long. The fitness of C. ferrugineus is not affected by the malathion resistance gene.

Use of an ambulation assistive device predicts functional decline associated with hospitalization
Article Abstract:
Research indicates that elderly patients with mobility impairment could maintain function by more intensive post-hospital and in-hospital rehabilitative therapy. Functional decline is substantially linked to mobility impairment. Risk for decline in activities of daily living (ADL) functions after discharge grew 2.8 times for those using a walker.

Long-term resistance training in the elderly: effects on dynamic strength, exercise capacity, muscle, and bone
Article Abstract:
A study of the strength and size of muscles, and bone mineral density in adults above 60 years of age undergoing an exercise training program for 42 weeks suggests that the dynamic strength and functional capacity of muscles and bones increases due to long-term exercise. However, the mineral density of the bones remains unaffected by exercise.
