We identified an open reading frame, designated phcS, downstream of the transcriptional activator gene (phcR) for the expression of multicomponent phenol hydroxylase (mPH) in Comamonas testosteroni R5. The deduced product of phcS was homologous to AphS of C. testosteroni TA441, which belongs to the GntR family of transcriptional regulators. The transformation of Pseudomonas aeruginosa PAO1c (ph...

For photonic crystals (PhCs) and related devices, it is useful to calculate the Dirichlet-to-Neumann (DtN) map of a unit cell, which maps the wave field to its normal derivative on the boundary. The DtN map can be used to avoid further calculations in the interiors of the unit cells and formulate mathematical problems on the cell boundaries. We develop a method to approximate the DtN map for tw...

RESULTS: The hMSCs in HCS still maintain self-renewal and differentiation capacity after extended periods of culture. The TGF-β1, ANG1 and ANG2 amount in PHCS was higher than HCS (p<0.05) whereas the VEGF amount in PHCS was significantly lower than that in HCS (p<0.05). The HCS and the PHCS implantation significantly reduced skin contraction and improved cosmetic appearance relative to the STSG...

Tapered silicon photonic crystals (PhCs) with smooth sidewalls are realized using a novel single-step deep reactive ion etching. The PhCs can significantly reduce the surface reflection over the wavelength range between the ultra-violet and near-infrared regions. From the measurements using a spectrophotometer and an angle-variable spectroscopic ellipsometer, the sub-wavelength periodic structu...

We examine photonic crystals PhC made of periodic stacks of anisotropic dielectric layers with a split band edge SBE on the band diagram. Just below the band edge frequency, the dispersion relation k of SBE PhCs can be approximated as a linear combination of a quadratic term and a quartic term. This is in contrast to regular conventional band edge PhCs, which produce a quadratic dispersion rela...

The Perceived Health Competence Scale (PHCS) is a measure of self-efficacy regarding general health-related behaviour. This brief paper examines the psychometric properties of the PHCS in a UK context. Questionnaires containing the PHCS, the SF-36 and questions about perceived health needs were posted to 486 patients randomly selected from a GP practice list. Complete questionnaires were return...

INTRODUCTION The Brazilian Government created Participatory Health Councils (PHCs) to allow citizen participation in the public health policy process. PHCs are advisory bodies that operate at all levels of government and that bring together different societal groups to monitor Brazil's health system. Today they are present in 98% of Brazilian cities, demonstrating their popularity and thus thei...

A case study is presented highlighting changes in geochemical conditions induced by the anaerobic degradation of petroleum hydrocarbons (PHCs) that enhanced the coalescence of dissolved phase PHCs into light non-aqueous phase liquid (LNAPL). Forensic analysis detected the presence of weathered light, middle and heavy weight PHCs in groundwater and LNAPL samples that were consistent with straigh...

Background The Nutrition Therapeutic Programme (NTP) involves the provision of food supplements at primary health clinics (PHCs) to correct nutritional deficiencies in vulnerable groups. Although previous studies have identified problems with implementing the programme at PHCs, assessments of its efficiency have been scarce. Objective To evaluate implementation of the NTP at PHCs that provide...
