Hydronium Ions Are Less Excluded from Hydrophobic Polymer-Water Interfaces than Hydroxide Ions.

The cloud point temperatures of aqueous poly(-isopropylacrylamide) (PNIPAM) and poly(ethylene) oxide (PEO) solutions were measured from pH 1.0 to pH 13.0 at a constant ionic strength of 100 mM.

Protoplast Transformation of Phytophthora spp.

At the core of assays to understand the role(s) of specific genes is the ability to stably transfer genes into Phytophthora through transformation. A key method for achieving this has been based on polyethylene glycol (PEG)/CaCl transformation of protoplasts, but efficiency has often been low. Improving transformation efficiency is necessary for many applications, such as gene knockouts.

RNA Silencing Strategies in Phytophthora: Experimental Guidelines and Insights.

RNA silencing is a core cellular process that acts to defend the genome against potentially damaging genetic elements such as viruses and transposons. It has been extensively characterized in many eukaryotes and exploited as a tool for determining gene function through removing the activity of specific genes. It has also been used in Phytophthora species to reveal genes involved in different lifecycle stages.

Manual Uterine Aspiration Simulation for Emergency Medicine Learners.

Introduction: Manual uterine aspiration is a potentially lifesaving procedure for treating patients with hemorrhagic complications of early pregnancy loss. While early pregnancy loss is a common diagnosis seen in the emergency department, manual uterine aspiration education is lacking for emergency medicine physicians.

Methods: We designed a 90-minute procedural skills training session for 30 emergency medicine learners.

Proteolytic processing of both RXLR and EER motifs in oomycete effectors.

Arg-any amino acid-Leu-Arg (RXLR) effectors are central oomycete virulence factors that suppress plant immunity. Relatively little is known about how they are processed post-translationally before delivery into host cells. A range of molecular, cell and biochemical processes were used to investigate proteolytic processing of RXLR and Glu-Glu-Arg (EER) motifs in Phytophthora infestans effectors.
