Cells injected with guanosine 5'-[alpha, beta-methylene]triphosphate, an alpha, beta-nonhydrolyzable analog of GTP, show anomalous patterns of tubulin polymerization affecting cell translocation, intracellular movement, and the organization of Golgi elements. [PDF]

Late blight pathogen targets host Rab‐G3 GTPases with an atypical GTPase‐activating protein
Journal of Integrative Plant Biology, EarlyView.The Phytophthora infestans RXLR effector Pi17063 functions as an atypical GTPase‐activating protein of host positive immune regulators, specifically the small GTPase NbRab‐G3. Pi17063 promotes the relocalization of NbRab‐G3 proteins to the cytoplasm, where they are inactive, disrupting the balance of the NbRab‐G3 switch and thus leading to enhanced ...

Hypotheses in light detection by vertebrate ancient opsin in the bird brain
Journal of Neuroendocrinology, EarlyView.Abstract Extra‐retinal photoreception is common across fish and avian species. In birds, the hypothalamus contains non‐visual photoreceptors that detect light and regulate multiple endocrine systems. To date, light‐dependent control of seasonal reproduction is one of the most well‐studied systems that require deep brain photoreception.

Ground testing of bioconvective variables such as morphological characterizations and mechanisms which regulate macroscopic patterns [PDF]
Conditions simulating low- and high-gravity, reveal changes in macroscopic pattern formation in selected microorganisms, but whether these structures are gravity dependent is not clear.

Journal of Periodontal Research, EarlyView.The certainty is moderate for a slightly higher platelet count in patients with periodontitis compared to individuals without periodontitis and low for no difference in mean platelet volume between the two groups. The evidence is not robust to claim a clear difference in other platelet activation biomarkers between the two groups.
