Prevalence and polarization of dental caries among young, healthy adults: Cross-sectional epidemiological study.

Objective: Oral health of young people has improved in the industrialized countries during past decades. However, stagnation of this progress has been reported recently. The main aim of this epidemiological study was to investigate the level of cariological treatment history and need (DMFT, DT) and polarization of dental caries among a healthy young male population born in the early 1990s.

Well development by jetting using coiled tubing and simultaneous pumping.

During flow testing of a deep, 1927-m, gravel packed screen completed well, it became apparent that well development was needed to increase productivity. A hydrojetting system using coiled tubing in combination with simultaneous pumping was developed and tested and found to be successful. To verify whether the jetting improved the well, the results of a pumping test conducted before and after the jetting operation are compared.

Widening of the inferior alveolar canal: a case report with atypical lymphocytic infiltration of the nerve.

Widening of the inferior alveolar (mandibular) canal is a rare radiological finding. It is most often associated with neurofibromatosis. Rarely, a malignant process such as lymphoma may cause ill-defined enlargement of the mandibular canal.

Dose conversion and cost effectiveness of erythropoietic therapies in chemotherapy-related anaemia : a meta-analysis.

Objective: To estimate a dose-conversion ratio (DCR) between epoetin alfa (EPO) and darbepoetin alfa (DARB) and compare the costs of both drugs at the estimated DCRs using average wholesale prices (AWPs).

Methods: A search of PUBMED, CANCERLIT and references for papers and abstracts reporting on clinical trials of DARB or EPO for chemotherapy-related anaemia (CRA) identified 56 publications. A meta-analysis was conducted on the 12 eligible papers to estimate a DCR at which the two drugs were equally effective as measured by the area under the curve of haemoglobin (Hb) change (Hb AUC) at weeks 4 and 13.

Parameter precision in the HBV-NP model and impacts on nitrogen scenario simulations in the Rönneå river, southern Sweden.

The HBV-NP model is a newly developed water quality model that describes the turnover and fluxes of both nitrogen and phosphorous. It is based on the conceptual precipitation/runoff HBV model. The HBV-NP model was applied for simulation of nitrogen for the Rönneå catchment in southern Sweden.
