When neurons in primary visual cortex of adult cats and monkeys are deprived of their normal sources of activation by matching lesions in the two retinas, they are capable of acquiring new receptive fields based on inputs from regions of intact retina around the lesions. Although these "reactivated" neurons respond to visual stimuli, quantitative studies of(More)
The effects of early discordant binocular vision on the fidelity of signal transfer in parvocellular neurons of the lateral geniculate nucleus (LGN) were investigated in rhesus monkeys reared with ocular misalignment (strabismus). Unilateral convergent strabismus (esotropia) was surgically induced in four infant monkeys between 20 and 30 days of age and the(More)
Periodontal disease is caused by dental plaque biofilms, and the removal of these biofilms from the root surface of teeth plays a central part in its treatment. The conventional treatment for periodontal disease fails to remove periodontal infection in a subset of cases, such as those with complicated root morphology. Adjunctive antimicrobial photodynamic(More)
Antimicrobial photodynamic therapy (aPDT) has been proposed as an adjunctive strategy for periodontitis treatments. However, use of aPDT for periodontal treatment is complicated by the difficulty in accessing morphologically complex lesions such as furcation involvement, which the irradiation beam (which is targeted parallel to the tooth axis into the(More)
We report the draft genome sequence of Microbacterium sp. strain HM58-2, which produces hydrazidase, an enzyme hydrolyzing acylhydrazides. The estimated genome size is 3.9 Mb. Genome sequence information of this strain will help to identify an assimilating mechanism of nonnatural compounds in this strain and to develop ecological applications.
OBJECTIVES In coronary artery bypass grafting (CABG), graft flow distal to a mild stenosis can compete with relatively preserved native flow through the stenosis and the competition can result in graft stenosis. In chronic total occlusion (CTO), coronary collateral circulation, which is essential to maintain myocardial viability distal to CTO, varies in(More)
A 54-year-old woman was admitted to our hospital with recurrent chest pain for 1 month. She had a history of aortic root replacement with a stentless valve following aortic valve replacements done twice 12 years ago, and coronary artery bypass grafting 6 years ago. The stentless valve was implanted with the full-root technique. After admission, she was(More)
Active infective endocarditis (IE) is classified into two groups; hospital acquired IE (HIE) and IE other than HIE, which was defined as community-acquired IE (CIE). Eighty-two patients underwent surgical treatment for active IE. Seventy-one cases were CIE group and eleven were HIE. There were six patients with native valve endocarditis and five cases of(More)
