OBJECTIVE Septic complications and the emergence of drug-resistant microbes represent serious risks to patients. Recently, naturally occurring peptides have been discovered that possess potent and broad-spectrum antimicrobial activity. Protegrin-1 is particularly attractive for clinical use in human wounds because, unlike defensins, protegrin-1 retains(More)
Fifty-five hemodialysis patients (pts) received rHuEpo for 3-5 years (51 +/- 11 months, hematocrit 32.5 +/- 3.7). BP medication was required in 42% of pts prior to rHuEpo (Hct 20.8 +/- 3.5) and 69% (38 patients) now require such therapy. BP was controlled with single therapy in 16 pts and only 8 required 3 or more different BP drugs. Vascular access(More)
RNAs of GB virus C (GBV-C) and hepatitis C virus (HCV) were sought by reverse-transcription polymerase chain reaction with nested primers deduced from the 5' untranslated region: 79 patients on maintenance hemodialysis, 205 commercial blood donors, and 205 voluntary donors in Beijing were studied. GBV-C RNA was detected in 43 (54%) patients and 17 (8%)(More)
While many endosymbionts have beneficial effects on hosts under specific ecological conditions, there can also be associated costs. In order to maximize their own fitness, hosts must facilitate symbiont persistence while preventing symbiont exploitation of resources, which may require tight regulation of symbiont populations. As a host ages, the ability to(More)
Resect a segment of canine cervical trachea. The length of resected trachea is from 1-4cm and 5-8cm. In the first group, one dog was used for each length and two dogs were used for each length in the second group, therefore twelve were used in the experiment. The upper and lower ends were matched and seved by three stitches, and OB glue was used to coat in(More)
