The attachment glycoprotein (G) of respiratory syncytial virus (RSV) is synthesized as two mature forms: a membrane-anchored form and a smaller secreted form. Mutant cDNAs were constructed that encoded one or the other form of the protein and were expressed in recombinant vaccinia viruses (rVV). Mice were immunized with rVV by dermal scarification or i.p. injection to determine the contribution...

Intradermal (ID) vaccination can offer improved immunity and simpler logistics of delivery, but its use in medicine is limited by the need for simple, reliable methods of ID delivery. ID injection by the Mantoux technique requires special training and may not reliably target skin, but is nonetheless used currently for BCG and rabies vaccination. Scarification using a bifurcated needle was exten...

BACKGROUND Tetanus is a severe infectious disease that can lead to death. The clinical manifestations are due to an exotoxin secreted by Clostridium tetani, a spore-producing Gram-positive bacillus. The penetration of the germ is made through a skin opening, independently of the size of the wound. CASE PRESENTATION A 13-year-old black African boy of the Bantu ethnic group with unknown tetanus...

One evening towards the close of last session, when a member of the Obstetrical Society exhibited an improved instrument for scarifying the gums of infants, and when several members began to express their opinions?some in favour of, and some .against the operation?it was suggested by Dr. Keiller that I should, at some subsequent meeting, bring up a paper on the subject which might serve as a ba...

Seeds have been reported to a combination of physical and physiological dormancy. However, this study revealed that H. dulcis seeds only The water absorption the after different periods sulfuric acid scarification was measured, gap through which absorbed treatment specified. Cold stratification gibberellic were performed determine whether had could absorb completely when scarified for more than...

Agricultural soils provide ecosystem services, but the removal of natural vegetation reduces water infiltration capacity, increasing surface runoff. Thus, monitoring erosion is critical for sustainable agricultural management. Sediment losses and runoff were evaluated using a simulated rainfall 75 mm/h in areas with crops pastures both Caiabi River Renato sub-basins Teles Pires watershed Mato G...
