Assessing global tendencies and impacts of conditional payments for environmental services (PES) programs is challenging because of their heterogeneity, and scarcity of comparative studies. This meta-study systematizes 55 PES schemes worldwide in a quantitative database. Using categorical principal component analysis to highlight clustering patterns, we reconfirm frequently hypothesized differe...

we present a case of unilateral tibia vara associated with an area of focal fibrocartilaginous dysplasia in the medial aspect of the right proximal tibia. such a case has not been described previously. the affected child was 8 months old. deformity resolved without aggressive treatment. the pathogenesis of the focal lesion remains controversial. the most likely explanation is that the mesenchym...

premature rupture of membranes (prom) is one of the most common complications of pregnancy that has a major impact on neonatal outcomes. with respect to racial, nutritional and cultural differences between developed and developing countries, this study was conducted to detect the prevalence of neonatal complications following prom and the role of the duration of rupture of membranes in producin...

Payments for environmental services (PES) have become a popular approach to address environmental degradation. However, evidence on its effectiveness is scarce and rather mixed. PES is not a panacea, but there are many cases where PES can be a promising tool. Yet, poor PES design translates into poor performance of the instrument. PES design is a complex task; the devil is in the detail of a nu...

Epidemic strains of Pseudomonas aeruginosa have been found worldwide among the cystic fibrosis (CF) patient population. Using pulse-field gel electrophoresis, the Prairie Epidemic Strain (PES) has recently been found in one-third of patients attending the Calgary Adult CF Clinic in Canada. Using multi-locus sequence typing, PES isolates from unrelated patients were found to consistently have ST...

Phthalate esters (PEs) are important environmental pollutants. While the biodegradation of the parent compound, phthalate (PTH), is well characterized, the biodegradation of PEs is not well understood. In particular, prior to this study, genes involved in the uptake and hydrolysis of these compounds were not conclusively identified. We found that Rhodococcus jostii RHA1 could grow on a variety ...
