New chemopreventive alternatives are needed due to the rising worldwide incidence of colorectal cancer. The objective was evaluate activity Moringa oleifera leaves (MO) in a colitis-associated colon carcinogenesis model. We hypothesized that MO contain bioactive compounds capable modulating expression genes involved inflammatory response and carcinogenesis. Forty-eight male mice (CD-1) were div...

Botulinum neurotoxin serotype A (BoNTA) causes a life-threatening neuroparalytic disease known as botulism that could afflict large, unprotected populations if the toxin were employed in an act of bioterrorism. Current post-exposure therapy is limited to symptomatic treatment or passive immunization that is effective for treating infant botulism at a cost of US $45,300 per treatment regimen. An...

We reconstructed a phylogeny for the seven species of doves in the genus Zenaidu on the basis of a combined analysis of mitochondrial (ND2 and cytochrome b) and nuclear (fibrinogen intron 7) DNA sequences. This phylogeny, which is completely resolved, is well supported with all nodes showing greater than 50% bootstrap support. There was no significant conflict between trees based on each gene i...

Fig.1: t-score maps showing resting state correlations with PCC/preCun (p<0.05). Right column: significant differences between patients and controls. Tab.1: Brain regions correlating significantly (p<0.05) with PC/preCun in controls. Negative t-scores indicate anticorrelation. Tab.2: Brain regions correlating significantly (p<0.05) with PC/preCun in patients. Negative tscores indicate anti-corr...

AIM/BACKGROUND Thymoquinone (TQ) is the major active principle of Nigella sativa seed (black seed) and is known to control many fungi, bacteria, and some viruses. However, the activity of TQ against anaerobic bacteria is not well demonstrated. Anaerobic bacteria can cause severe infections, including diarrhea, aspiration pneumonia, and brain abscess, particularly in immunodeficient individuals....

Lines are one of the basic primitives used by the perceptual system to analyze and interpret a scene. Therefore, line detection is a very important issue for the robustness and flexibility of Computer Vision systems. However, in the case of images showing a significant lens distortion, standard line detection methods fail because lines are not straight. In this paper we present a new technique ...
