DESCRIPTIONS OF TWO SPECIES OF ANAPHORA [PDF]

open access: yesThe Canadian Entomologist, 1872
In Dr. Clemens Tineid genus Anaphora,the fore wings are 12-Veined. The submedian fold, however, seems to me to become a true vein towards the margin, giving an additional vein (vein 1b). Internal nervure, vein 1a, shortly furcate at base. Median nervure sending out vein 2 near the extremity to internal angle ; and emitting 3 and 4, nearer together, on ...

Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
