Direct rooting and rooting via a wound tissue in Pinus sylvestris L. and Pinus contorta Dougl. ex Loud. hypocotyl cuttings in vitro were studied. Direct rooting usually occurred within three weeks after cutting. Three to four weeks after cutting, roots developed either directly on the hypocotyl or via a wound tissue. Later than one month after cutting, rooting took place predominantly via a wou...

If, in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence passed on to the next generations of creatures, what statement would contain the most information in the fewest words? I believe it is the atomic hypothesis (or the atomic fact, or whatever you wish to call it) that all things are made of atoms—little particles that move around in perpetual motion, at...

INTRODUCTION Social functioning is a core domain in the life of people with dementia, but there is no accepted instrument to measure it.

METHODS We interviewed people with mild dementia and family caregivers to develop patient and ca...

BACKGROUND AND PURPOSE Vertebroplasty is rapidly disseminating as a treatment for vertebral compression fractures, but its efficacy has not been assessed with a well-validated, back pain-specific instrument. We report the use of the Roland-Morris Disability Questionnaire (RDQ) in patients undergoing vertebroplasty for painful osteoporotic compression fractures. METHODS Retrospective review of...

PURPOSE The study aim was to develop a measure of self-reported quality of life (QoL) for people with mild to moderate dementia based on their views-the Bath Assessment of Subjective Quality of Life in Dementia (BASQID). DESIGN AND METHODS We developed the measure through multiple stages. Two field tests of the measure (ns = 60 and 150) enrolled people with dementia from a memory clinic, and ...

BACKGROUND Dementia is becoming a major public health problem in Latin America (LA), yet epidemiological information on dementia remains scarce in this region. This study analyzes data from epidemiological studies on the prevalence of dementia in LA and compares the prevalence of dementia and its causes across countries in LA and attempts to clarify differences from those of developed regions o...

OBJECTIVE Dementia is a debilitating illness with a disproportionate burden in patients with type 2 diabetes (T2D). Among the contributors, genetic variation at the apolipoprotein E locus (APOE) is posited to convey a strong effect. This study compared and contrasted the association of APOE with cognitive performance and cerebral structure in the setting of T2D. RESEARCH DESIGN AND METHODS Eu...

OBJECTIVE Our aim was to compare 2 Framingham vascular risk scores with a dementia risk score in relation to 10-year cognitive decline in late middle age. METHODS Participants were men and women with mean age of 55.6 years at baseline, from the Whitehall II study, a longitudinal British cohort study. We compared the Framingham general cardiovascular disease risk score and the Framingham strok...
