BACKGROUND Maternal cervical incompetence in pregnancy (CIP) showed an association with a higher rate of preterm births. The objective of this study was to determine the prevalence of CIP in Hungarian pregnant women, to determine the rate of preterm birth, and to check the preventive efficacy of preterm births due to CIP by therapeutic cerclage or bed rest alone. METHODS Analysis of the popul...

SETTING Malmö, Sweden. PARTICIPANTS 9351 women, aged 28-55, with a mean follow up of 10.7 years. MAIN RESULTS Smoking, hypertension ...

BACKGROUND Atrophy of rotator cuff muscles has been considered an irreversible phenomenon. The purpose of this study is to evaluate whether atrophy is truly irreversible after rotator cuff repair. METHODS We measured supraspinatus muscle atrophy of 191 patients with full-thickness rotator cuff tears on preoperative magnetic resonance imaging and postoperative multidetector computed tomography...

The aim of this study was to investigate human papillomavirus (HPV) infection and HPV genotype distributions in Urumqi, Xinjiang, China. The related risk factors for high-risk HPV infection was also analyzed. A stratified cluster sampling method was used for the population-based cervical cancer screening of women aged 18-69 years in the Urumqi Saybagh district. Exfoliated cervical cell samples ...

A 3-year entomological study was carried out on the transmission of malaria in a village of 900 inhabitants in a rice-growing area of Burkina Faso. In the study area inhabitants use bed nets to protect themselves from mosquito bites. In the first year of the study, baseline data were collected; in the second year, the village was divided in two parts and all the bed nets in the southern part we...

Hydrodynamics has a strong influence on substrate elimination capacity in trickle-bed bioreactors (TBB). The present study reports the influence of liquid mass flow rate and bed void fraction on the TBB liquid residence time distribution (RTD), gas-liquid pressure drop, liquid hold-up, and biofilm wetting efficiency. Most RTD are well represented by a dispersion model. It is also shown that the...

A fluidized bed reactor with ultraviolet lamp and TiO2/silica photo-catalyst prepared in our laboratory was used as a photo-reactor to degrade toluene in a simulated toluene-air mixture. The effects of operating parameters including initial toluene concentration, superficial gas velocity, ultraviolet light intensity and catalyst bed height on degradation rate of toluene have been investigated i...
