Photobiomodulation on Full-Thickness Skin Graft Survival in Rats.

Objective: To evaluate the photobiomodulation effects on the receptor area for full-thickness skin graft integration.

Methods: Thirty-Six Wistar rats were divided: red laser (660 nm), infrared laser (808 nm), and control. A skin segment with 5 × 3 cm was removed.

Occurrence and Origin of Supernumerary Chromosomes in Partamona (Hymenoptera: Apidae: Meliponini).

Samples from 861 colonies of 12 Partamona species from 125 Brazilian localities were analysed for a SCAR marker specific to the B chromosomes of P. helleri. We identified the SCAR marker in 6 of the 12 species analysed, including 2 (P.
