By following previous method proceedings, a lectin was purified and characterized from Pisum sativum L. (Pea, Papilionaceae, Leguminosae) seeds through combination of one Sephadex G-75 gel filtration chromatography and a reverse phase HPLC in -Bondapack C18 column. The analysis in bidimentional electrophoresis (2D) showed a protein spot of 14 KDa and an isoelectrical point of 7.5. The molecular weight of 14 kDa was confirmed by mass spectrometry MALDI -TOF in 14 662.0 Da. The aminoacid composition showed an hydrophobical protein with basic features and bioinformatic analysis of the N-terminal sequence showed homology with other vegetable lectins. Likewise, most outstanding physical-chemical characteristics were: the glicoprotein nature and its specificity by D- mannose and D- glucose,the Ca2+ dependence and Mn2+ in order to show hemnogglutinan activity. The study of the fungicidal activi...

The success of a rehabilitation on implants lies in the correct three-dimensional positioning of the implant and a surgical guide that has been previously planned with a resale protocol brings us closer to that objective; the ROGA surgical guide is created that aims to be more effective than the freehand technique in such positioning; To evaluate it, 8 implants were placed with ROGA Guide and 8 implants freehand, and then the three-dimensional positioning was evaluated using the before and after tomographs, 5 measurements, mesiodistal and palatal vestibule both at coronal level and at apical and apicocoronal level were evaluated ; the implants placed with the ROGA guide did not have any deviation at the coronal mesiodistal level and in the other measures they had less deviations in relation to the reverse planning with an average of 0.457mm unlike the raised hand that had an average devi...

University students in their daily activity experience a diverse range of academic responsibilities. including main duties, such as: projects, tasks and tests. Situations in which the student might experience anxiety, insecurity, lack of control, fear of failure, etc. which may not be perceived by the student, and that if that stress is not controlled and moderate appropriately it could have negative effects on academic performance, and in severe cases it could lead to the university academic failure (1). The main objective of this research study is to apply a non-invasive and inexpensive method to measure salivary amylase, which is considered a biomarker of stress by the interaction between the endocrine, immune and nervous acting adrenergic response. We proceeded to assess levels of variation in saliva in order to perceive stress in students at the beginning and end of the assessment f...
