Contrasting Weather and Stocking Effects on Initial Coppice Response in Brazil.

In plantations, coppice rotations often yield less than initial rotations. The TECHS project (Tolerance of Clones to Hydric, Thermal and Biotic Stresses) studied short rotation coppicing across a 3000 km gradient. The main objective of this work was to compare the survival, sprouting, and initial growth of clones managed and to examine factors that might influence the productivity of the coppice rotation: climate, genotypes, and stocking.

Relative efficacy of anti-Plasmodium vivax malaria combination drugs in preventing transmission to two major Anopheles mosquitoes in the first few days of treatment.

Objectives: The World Health Organization recommends three drug anti-malarial combinations: cloroquine+primaquine, artesiminin+primaquine, and cloroquine+tafenoquine. These combinations aim to eradicate Plasmodium by disrupting its life cycle within the human body. We evaluated the effect of these medications on the vectorial competence of two main vectors in the New World.

Reduced staining from a chlorhexidine mouthwash: A randomized clinical trial.

Purpose: To investigate the stain preventing ability of a new chlorhexidine mouthwash while maintaining efficacy using a randomized clinical trial design.

Methods: 98 subjects were enrolled and completed a 4-week clinical study that evaluated the effectiveness of the new mouthwash on plaque, gingivitis, and staining as compared to a commercially available chlorhexidine mouthwash. A subset of 62 subjects was evaluated for the effectiveness of the mouthwashes against plaque bacteria.

Morphometry of the wings of Anopheles aquasalis in simulated scenarios of climate change.

Background: Climate change has significant implications on ecosystems. We verified the effects of climate change on the malaria vector Anopheles aquasalis using simulated climate change scenarios (SSCCs).

Methods: An experimental model was designed for SSCCs, which composed of air-conditioned 25 m3 rooms.
