047) and its distance of existence < 1 km from the house(OR = 2.1; 95% CI 2.0-15.8, p = 0.001) were more likely to be infected TPCA-1 with malaria parasite compared with those who live away from stagnant at a distance greater than 1 km.

Conclusion: Malaria is a major health problem with P. vivax becoming a predominant species in the town. The prevalence was strongly associated with proximity of residence to potential

mosquito breeding sites. Malaria is affecting significant proportions of the urban settlers and human activities nevertheless play an important role in bringing the mosquito breeding sites closer to residences.”
“Objective. This study compared the healing of 2 laser ablation units, erbium YAG and femtosecond lasers versus conventional mechanical cutting with carbide and diamond drills to explore future applications for bone surgery. The effects of laser or mechanical ablation combined with rhBMP-7 were also investigated.

Methods and materials. Following defect standardization, a full-thickness circular defect was created on the parietal bones of 160 mice divided into 4 groups: carbide DZNeP solubility dmso drill, diamond drill, erbium YAG laser, and femtosecond

laser. Each of the 4 ablation groups was treated with and without BMP 7. Hard tissue healing was assessed using microcomputerized tomography at 3 and 12 weeks postsurgical time points.

Results. The femtosecond laser created wounds that showed slightly delayed bone healing during the observation period when compared with mechanical drilling, although the difference was not statistically significant. The Er:YAG laser showed a healing rate similar to that of the mechanically ablated groups. When BMP 7 was added to the surgical

sites, bone wound closure occurred at a similar rate in all test groups.

Conclusions. The femtosecond and Er:YAG lasers are 2 laser modalities suitable for bone ablation that are comparable to mechanical instrumentation in terms of bone healing. This study suggested that BMP-7 may be used to enhance bone healing with this website success regardless of the ablative modality used, whether laser or mechanical drilling.

“Genetic and epigenetic factors affecting DNA methylation and gene expression are known to be involved in the development of colon cancer, but the full range of genetic alterations and many key genes involved in the pathogenesis of colon cancer remain to be identified. NPRL2 is a candidate tumor suppressor gene identified in the human chromosome 3p21.3 region. We evaluated the role of this gene in the pathogenesis of colorectal cancer by investigating NPRL2 mRNA expression in 55 matched normal and tumor colon tissue samples using quantitative RT-PCR analysis. There was significantly decreased NPRL2 expression in 45% of the patients. Lower NPRL2 expression was observed significantly more frequently in poorly differentiated tumor samples than in highly or moderately differentiated tumors.
