Metronomic chemotherapy: bridging theory to clinical application in canine and feline oncology.

Veterinary oncology has experienced significant evolution over the last few decades, with chemotherapy being currently applied to several neoplasms with therapeutic success. Traditionally, chemotherapy protocols are based on classic cytostatic drugs under the concept of maximum tolerated dose (MTD), which has been associated with a greater risk of toxicity and resistance. Thus, new therapeutic alternatives have emerged, such as metronomic chemotherapy (MC), introducing a new paradigm in cancer treatment.

Imaging of glyphosate uptake and identification of early microscopic markers in leaves of C3 and C4 glyphosate-resistant and -susceptible species.

Details of glyphosate uptake are not fully elucidated, and although this herbicide promotes important alterations in the plant phenotype few hours after its application (early responses), a detailed description of the presumable changes in plant anatomy is still poorly assessed by now. Due to glyphosate effects over leaf permeability, the use of an inert fluorescent tracer may allow the observation of the uptake event in situ. In addition, microscopic markers might put a light on the recognition of glyphosate-resistant (GR) and -susceptible (GS) species or varieties, which may vary in C3 and C4 species due to their putative distinct leaf anatomy.
