Extratropical cyclone climatology across eastern Canada
Plante, Mathieu,Son, Seok‐,Woo,Atallah, Eyad,Gyakum, John,Grise, Kevin John Wiley Sons, Ltd 2015 International journal of climatology Vol.35 No.10
<P><B>ABSTRACT</B></P><P>Extratropical cyclone (ETC) tracks across eastern Canada are examined by applying a Lagrangian tracking algorithm to the lower‐tropospheric relative vorticity field of reanalysis data. Both the seasonal cycle and the interannual variability of ETCs are quantified in terms of overall cyclone frequency, intensity, and regions of development and decay. We find that ETCs travelling to eastern Canada tend to develop over the Rockies, the Great Lakes and the US East Coast. The ETCs are most intense over Newfoundland and the North Atlantic Ocean, confirming previous findings. While ETCs at cities along the Atlantic coastline (e.g. St. John's) are dominated by East Coast cyclones (which are intense in winter), those inland (e.g. Toronto) track primarily from the Great Lakes. ETCs that develop over the Gulf of Mexico affect eastern Canada infrequently, but those that do tend to be intense. The interannual variability of the wintertime ETCs is influenced by the El Niño‐Southern Oscillation (ENSO). Significant ENSO‐related variability is found over most regions of southern Canada, except on the east coast. Although ETCs at Toronto are significantly modulated by ENSO, no visible changes are found at St. John's. These ENSO‐related ETC changes are mostly due to the shifts in ETC development regions, with minor changes in the travelling direction of ETCs.</P>

<P><B>Abstract</B></P><P>The 5′ region of <I>Potato virus X</I> (PVX) RNA containing an AC-rich single-stranded region and stem–loop 1 (SL1) has been shown to be important for PVX replication (Miller, E.D., Plante, C.A., Kim, K.-H., Brown, J.W., Hemenway, C., 1998. Stem–loop structure in the 5′ region of potato virus X genome required for plus-strand RNA accumulation. J. Mol. Biol. 284, 591–608.). Here, we describe the involvement of SL1 for binding to the PVX coat protein (CP) using an in vitro assembly system and various deletion mutants of the 5′ region of PVX RNA. Internal and 5′ terminal deletions of the 5′-nontranslated region of PVX RNA were assessed for their effects on formation of assembled virus-like particles (VLPs). Mutant RNAs that contain the top region of SL1 or sequences therein bound to CP to form VLPs. In contrast, transcripts of mutants that disrupt SL1 RNA structure were unable to form VLPs. SELEX was used to further confirm the specific RNA recognition of PVX CP using RNA transcripts containing randomized sequences of the upper portion of SL1. Wild-type (wt) sequences along with many other sequences that resemble SL1 structure were selected after fourth and fifth rounds of SELEX (27.0% and 44.4%, respectively). RNA transcripts from several SELEX winners that are predicted to form stable stem–loop structures very closely resembling wt PVX SL1 VLPs. RNA transcripts not predicted to form secondary structures similar to SL1 did not form VLPs in vitro. Taken together, our results suggest that RNA secondary structural elements within SL1 and/or sequences therein are crucial for formation of VLPs and are required for the specific recognition by the CP subunit.</P>
A shark attack treated in a tertiary care centre: Case report and review of the literature
Roy, Melissa,Plant, Mathew A,Snell, Laura Korean Society of Plastic and Reconstructive Surge 2018 Archives of Plastic Surgery Vol.45 No.1
Although uncommon, shark attacks can lead to devastating outcomes for victims. Surgeons also face unique challenges during operative management such as exsanguination, shock, specific injury patterns and infections. This case report presents the management of a 39-year-old previously healthy female attacked by a shark while on vacation in Mexico. The patient sustained severe injuries to her left arm and her left thigh. She was transferred to a Canadian institution after ambiguous operative management in Mexico and presented with no clear antibiotic coverage and a Volkman's contracture of the left upper extremity. In total, the patient underwent four washouts of wounds, two split-thickness skin grafts, one free anterolateral thigh flap, and one free transverse rectus abdominus myocutaneous flap for the reconstruction and salvage of the left lower extremity. This article highlights the specifics of this case and describes important points in managing these devastating injuries.

<P>We report the generation of optical pulse trains with 380 as of residual timing jitter (1 Hz-1 MHz) from a mode-locked external-cavity semiconductor laser, through a combination of optimizing the intracavity dispersion and utilizing a high-power, low-noise InGaAsP quantum-well slab-coupled optical waveguide amplifier gain medium. This is, to our knowledge, the lowest residual timing jitter reported to date from an actively mode-locked laser.</P>
