Exercise programs that are individualized and moderately challenge balance to address falls risk factors are recommended for preventing falls in community-dwelling older adults. Little is known regarding the biomechanical and postural control demands in exercises commonly performed in falls prevention programs. Twenty-two non-sedentary, healthy older adults (11 men, 11 women,...
Common variable immunodeficiency (CVID) is the most common primary immunodeficiency that is characterized by low immunoglobulin levels in the body. CVID is indicated by failure of b cell differentiation and decrease production of immunoglobulins such as IgG and at least one of IgA or IgM. CVID patients with enteropathy (E-CVID)...
We have used the sequence-specific endonucleases Eco RI, Sma I,
Bam HI, Hsu I and Hae III as identification tools in following the
conjugal transfer of the well studied R plasmids Sa, R388, RP4 and R6K.
Transfers were both intergenus and intragenus. Plasmid fingerprints
were generated from both single and...
Aging and excessive weight appear to be problematic to lateral balance related to falls. Strong frontal plane hip muscle strength is needed to stabilize the hip statically during single leg stance or dynamically during lateral stepping; however, the length of single leg stance time and maximum hip abduction angle during...
Falls in older adults are a significant issue in the United States. Many older adults are advised to participate in fall prevention exercise programs in an attempt to increase strength and stability, but it is unclear what role limb dominance and potential limb asymmetry has in exercise performance. The purpose...
The mound-building harvester ant, Pogonmyrmex owyheei Cole,
(formerly included in the species occidentals) is widely distributed
on the semi-arid rangeland east of the Cascade mountains in Oregon.
Because of its seed foraging and vegetation clearing habits, this ant
has been considered as a possible competitor with livestock and
wildlife for...
