Network analysis of ballast-mediated species transfer reveals important introduction and dispersal patterns in the Arctic [PDF]

open access: yesarXiv, 2020
Rapid climate change has wide-ranging implications for the Arctic region, including sea ice loss, increased geopolitical attention, and expanding economic activity, including a dramatic increase in shipping activity. As a result, the risk of harmful non-native marine species being introduced into this critical region will increase unless policy and ...

Arctic curves of the six-vertex model on generic domains: the Tangent Method [PDF]

open access: yesJ. Stat. Phys. 164 (2016) 1488, 2016
We revisit the problem of determining the Arctic curve in the six-vertex model with domain wall boundary conditions. We describe an alternative method, by which we recover the previously conjectured analytic expression in the square domain. We adapt the method to work for a large class of domains, and for other models exhibiting limit shape phenomena ...

To the Arctic, For the Arctic

open access: yesEarth Common Journal, 2012
To the Arctic (Judson, MacGillivray & MacGillivray, 2011), the new documentary in IMAX format, which stands for Image Maximum, “a motion picture format with the capacity for greater size and clearer resolution than standard movie systems” (Tech-FAQ, 2012), reveals the verifiable impacts of global warming on the Arctic so that humans can see and ...

The Useless Arctic: Exploiting Nature in the Arctic in the 1870s

open access: yesNordlit, 2015
<p align="LEFT">What is the discursive genealogy of an ecological approach to the Arctic? Building on distinctions suggested by Francis Spufford and Gísli Pálsson, this article examines a specific juncture in the history of European–Arctic interaction – the reception of the Austro-Hungarian Arctic Expedition in 1874 – and traces the potential for

STAT3 expression is reduced in cardiac pericytes in HFpEF and its loss reduces cellular adhesion and induces pericyte senescence

open access: yesFEBS Letters, EarlyView.
Heart failure with preserved ejection fraction (HFpEF) accounts for half of the heart failure cases. It is characterised by microvascular dysfunction, associated with reduced pericyte coverage and diminished STAT3 expression in pericytes. Loss of STAT3 impairs pericyte adhesion, promotes senescence, and activates a pro‐fibrotic gene program.

Complex lifestyle intervention among inactive older adults with elevated cardiovascular disease risk and obesity: a mixed-method, single-arm feasibility study for RESTART—a randomized controlled trial

open access: yesPilot and Feasibility Studies, 2021
Background Physical inactivity and obesity are global public health challenges. Older adults are important to target for prevention and management of disease and chronic conditions.

The Enigma of Interspecific Plasmodesmata: Insight From Parasitic Plants

open access: yesFrontiers in Plant Science, 2021
Parasitic plants live in intimate physical connection with other plants serving as their hosts. These host plants provide the inorganic and organic compounds that the parasites need for their propagation.

The Arctic Cloud Puzzle: Using ACLOUD/PASCAL Multiplatform Observations to Unravel the Role of Clouds and Aerosol Particles in Arctic Amplification

open access: yesBulletin of The American Meteorological Society - (BAMS), 2019
Clouds play an important role in Arctic amplification. This term represents the recently observed enhanced warming of the Arctic relative to the global increase of near-surface air temperature.

Cytoplasmic delivery of antibodies through grafting a functional single complementarity‐determining region loop

open access: yesFEBS Letters, EarlyView.
We achieved cytoplasmic delivery of non‐cell‐penetrating IgGs by grafting a single functional complementarity‐determining region 1 (CDR1) from the light chain variable region (VL) of the cell‐internalizable 3D8 antibody. The engineered IgG acquired cell‐penetrating ability while maintaining antigen affinity, highlighting CDR1 grafting as a promising ...

Modifications in FLAP's second cytosolic loop influence 5‐LOX interaction, inhibitor binding, and leukotriene formation

open access: yesFEBS Letters, EarlyView.
The enzyme 5‐lipoxygenase (5‐LOX) catalyzes the first step in the biosynthesis of leukotrienes (LTs) involved in inflammatory pathophysiology. After cellular stimulation, 5‐LOX translocates to the nucleus, interacting with the 5‐LOX‐activating protein (FLAP) to form LTA4 from arachidonic acid (AA).
