Quality adjustment weights for quality-adjusted life years (QALYs) are available with the EQ-5D Instrument, which are based on a survey that quantified the preferences of the British public. However, the extent to which this British value set is applicable to other, especially non-European, countries is yet unclear. The objectives of this study are (a) to(More)
Although the threshold of cost effectiveness of medical interventions is thought to be 20 000- 30 000 UK pounds in the UK, and $50 000-$100 000 in the US, it is well known that these values are unjustified, due to lack of explicit scientific evidence. We measured willingness-to-pay (WTP) for one additional quality-adjusted life-year gained to determine the(More)
Accurate voice activity detection (VAD) is important for robust automatic speech recognition (ASR) systems. This paper proposes a statistical-model-based noise-robust VAD algorithm using long-term temporal information and harmonic-structure-based features in speech. Long-term temporal information has recently become an ASR focus, but has not yet been deeply(More)
Staphyloxanthin, a yellow pigment produced by methicillin-resistant Staphylococcus aureus (MRSA), is a virulent factor escaping from the host immune system. A new screening method for inhibitors of staphyloxanthin production by MRSA was established using paper disks. By this screening method, inhibitors of staphyloxanthin production were selected from the(More)
Two new furopyrrols, designated tensidols A and B, were isolated from the culture broth of Aspergillus niger FKI-2342 by solvent extraction, silica gel column chromatography and HPLC. Their structures were elucidated and shown to have the common skeleton of 6-benzyl-6H-furo[2,3-b]pyrrole. Tensidols A and B potentiated miconazole activity against Candida(More)
Two new phenols, designated phenatic acids A and B, were isolated along with known actiphenol, from the culture of Streptomyces sp. K03-0132 by solvent extraction, silica gel column chromatography and HPLC. Their structures were elucidated by spectroscopic analyses including mainly various NMR experiments. They have a common 1-hydroxy 2, 4-dimethyl benzene(More)
A case of primary Hodgkin's disease, a lymphocyte-predominant entity, occurring in the stomach is described. The patient was a 37-year-old man who complained of general fatigue. Endoscopic biopsy revealed gastric malignant lymphoma. Subtotal gastrectomy and postoperative chemotherapy following a modifid CHOP regimen were performed. The patient has been free(More)
Longitudinal alterations in anaerobic threshold (AT) and distance running performance were assessed three times within a 4-month period of intensive training, using 20 male, trained middle-distance runners (19–23 yr). A major effect of the high intensity regular intensive training together with 60- to 90-min AT level running training (2d ·wk −1) was a(More)
