Oxalate secretion by ectomycorrhizal Paxillus involutus is mineral-specific and controls calcium weathering from minerals

Source: https://www.nature.com/ Abstract Trees and their associated rhizosphere organisms play a major role in mineral weathering driving calcium fluxes from the continents to the oceans that ultimately control long-term atmospheric CO2 and climate through the geochemical carbon cycle. Photosynthate allocation to tree roots and their mycorrhizal fungi is hypothesized to fuel the active secretion of protons and organic chelators that enhance calcium dissolution at fungal-mineral interfaces. This was tested using 14CO2 supplied to shoots of Pinus sylvestris ectomycorrhizal with the widespread fungus Paxillus involutus in monoxenic microcosms, revealing preferential allocation by the fungus of plant photoassimilate to weather grains of limestone and silicates each with a combined calcium and magnesium content of over 10 wt.%. Hyphae had acidic surfaces and linear accumulation...

Rab18 Facilitates Dengue Virus Infection by Targeting Fatty Acid Synthase to Sites of Viral Replication

Source: https://jvi.asm.org/ ABSTRACT Positive-sense RNA viruses, such as dengue virus (DENV), hijack the intracellular membrane machinery for their own replication. The Rab18 protein, a member of the Rab GTPase family, key regulators of membrane trafficking, is located on the organelles involved in DENV infection, such as the endoplasmic reticulum (ER) and lipid droplets (LDs). In this study, we addressed the potential involvement of Rab18 in DENV infection by using cells overexpressing the wild-type, GTP-bound active form, or GDP-bound inactive form of Rab18 and cells with Rab18 knockdown. DENV replication, measured by viral protein, viral RNA, and viral progeny production, as well as LD induction, was reduced in cells with inactive Rab18 and in cells deprived of Rab18 expression, suggesting a positive...

Enter the Dr PRP separation kit. The latest in medical innovations.

DR MAUREEN ALLEM introduces a novel medical kit designed for PRP separation that is not only fast and efficient, but undertakes to deliver effective results. American businesswoman Anne Sweeney (president of Disney Media and the Disney Channel) once said: “I’m naturally curious, and I’ve always been driven by my curiosity. Curiosity gets people excited. Curiosity leads to new ideas.”At Skin Renewal, we can identify with this – and in the exciting field of aesthetics, we get the opportunity to inspect and evaluate the tremendous developments to stimulate our curiosity. The phenomenon that is PRP PRP (platelet rich plasma) injections have recently been highlighted in the media, specifically for aesthetic procedures. This unique and innovative procedurehas earned it nicknames such as...
