Opsonophagocytic killing of some bacteria (Staphylococcus aureus, Pseudomonas aeruginosa) by phagocytes is enhanced by previous brief exposure of the organism to antibiotics. We studied the regrowth of Legionella pneumophila previously pretreated with levofloxacin, erythromycin and/or rifampicin in human monocytes. The MIC for the L. pneumophila isolate of levofloxacin, erythromycin and rifampi...

Dry matter accumulation, nitrate reductase activity of various organs, nitrate accumulation, nitrogen derived from nitrate, and nitrogen content were studied during 17 days of vegetative regrowth of harvested (detopped) alfalfa (Medicago sativa L.). Seedlings were grown in the glasshouse and treated with 0, 40, and 80 kilograms N per hectare applied as K(15)NO(3) to determine whether reduced ni...

Little is known about how the surrounding modified matrix affects tree recruitment in fragmented forests. We contrasted effects of two different matrix types, Vismia- and Cecropia-dominated regrowth, on recruitment of pioneer tree species in forest fragments in central Amazonia. Our analyses were based on 22, 1-ha plots in seven experimental forest fragments ranging in size from 1 to 100 ha. By...

Muscle atrophy contributes to morbidity and mortality in aging and chronic disease, emphasizing the need to gain understanding of mechanisms involved in muscle atrophy and (re)growth. We hypothesized that the magnitude of muscle regrowth during recovery from atrophy determines if myonuclear accretion and myogenic differentiation are required, and that Insulin-like Growth Factor-I (IGF-I)/Akt/ G...

Adult zebrafish, in contrast to mammals, regrow axons descending from the brainstem after spinal cord transection. L1.1, a homolog of the mammalian recognition molecule L1, is upregulated by brainstem neurons during axon regrowth. However, its functional relevance for regeneration is unclear. Here, we show with a novel morpholino-based approach that reducing L1.1 protein expression leads to imp...

Development of de novo aneurysm or aneurysm regrowth after complete clipping of an intracranial aneurysm is rare. We report coiled cases of de novo aneurysm and aneurysm regrowth. We retrospectively reviewed 107 cases of intracranial aneurysm coiling performed in our hospital, identifying five cases of coiled aneurysm that were de novo aneurysm or aneurysm regrowth. In all the cases, total or n...

Onychomadesis usually arises from an inflammation of the paronychium or as a result of blisters and hemorrhaging under a nail that has been struck or compressed. No documented interactions between basic fibroblast growth factor (bFGF) and onychomadesis have hitherto been reported. This case report describes a 25-year-old woman with onychomadesis following infection of the ingrown nail of her le...

Ohmic regrowth by molecular beam epitaxy (MBE) has been investigated for metal-face InAlN/AlN/GaN high electron mobility transistors (HEMTs) for the first time. Using SiO2 mask nþ-GaN was regrown in the source/drain region while deposition on the mask was lifted off in buffered HF after regrowth. The lowest contact resistance measured was 0.40 0.23Vmm by the transmission line method (TLM) in th...
