Marine Operations in the Norwegian Sea and the Ice-Free Part of the Barents Sea with Emphasis on Polar Low Pressures

The Arctic Seas are attractive for shipping, fisheries, and other marine activities due to the abundant resources of the Arctic. The shrinking ice cover allows for the opening of activities in increasingly larger areas of the Arctic. This paper evaluates the possibility of executing all-year complex marine activities, here termed “marine operations”, in the Norwegian Sea and the ice-free part of the Barents Sea. The approach used during the preparation of this review paper is to identify constraints to marine operations so users can be aware of the limitations of performing such operations. The weather conditions in the Norwegian Sea and the Barents Sea are well known, and these seas are considered representative of ice-free or partly ice-free Arctic Seas with considerable marine activities. Similar conditions could be expected for other Arctic Seas during periods without ice cover. Marine operations require safe and stable working conditions for several days. The characteristics of marine operations are discussed, and the particulars of the Norwegian Sea and the Barents Sea physical environments are highlighted. Emphasis is on the wind and wave conditions in unpredictable polar low-pressure situations. Furthermore, situations with fog are discussed. The large uncertainties in forecasting the initiation and the tracks of polar lows represent the main concern for executing marine operations all year. Improvements in forecasting the occurrence and the path of polar lows would extend the weather window when marine operations could be carried out. Discussions of the potential for similar conditions in the wider Arctic Seas during ice-free periods are presented.

Evidence Supporting Conservative Scar Management Interventions Following Burn Injury: a review article.

Conservative management for hypertrophic scars (HSc) and scar contractures is of utmost importance to optimally reintegrate burn survivors into society. Many conservative treatment interventions have been described in the literature for the management of HSc. Recent advancements in the literature pertaining to post-burn scarring and HSc formation, have advanced our understanding of the mechanisms that support or refute the use of common rehabilitation treatment modalities after burn injury. This is particularly relevant for recent advancements in the fields of mechanotransduction and neurogenic inflammation resulting in the need for rehabilitation clinicians to reflect upon commonly employed treatment interventions. The aim of this review article is to summarize and clinically apply the evidence that supports or refutes the use of common conservative treatment interventions for scar management employed after burn injury. The following treatments are discussed and mechanotransduction and neurogenic inflammation concepts are highlighted: 1) edema management (compression, positioning/elevation, pumping exercises, retrograde massage, manual edema mobilization), 2) pressure therapy (including custom fabricated pressure garments, inserts, face masks, and other low-load long duration orthotic devices), 3) gels or gel sheets, 4) combined pressure therapy and gels, 5) serial casting, 6) scar massage, and 7) passive stretching. This review supports the following statements: 1) Compression for edema reduction should be initiated 48-72 hrs post-injury and continued for wounds that require longer than 21 days to heal until scar maturation; 2) Elevation, pumping exercises and retrograde massage/MEM should be used in combination with other edema management techniques; 3) Custom fabricated pressure garments should be applied once the edema is stabilized and adequate healing has occurred. Garments should be monitored on a regular basis to ensure that optional pressure, >15mm Hg, is maintained, adding inserts when necessary. The wearing time should be >16 hrs/day; 4) Gels for post-burn scar management should extend beyond the scar; 5) Serial casting should be applied when contractures interfere with function; 6) Forceful scar massage should be avoided early in the wound healing process or when the scar is inflamed or breaks down; 7) Other treatment modalities should be prioritized over passive stretching for scar management.

Extreme Events Contributing to Tipping Elements and Tipping Points

AbstractThis review article provides a synthesis and perspective on how weather and climate extreme events can play a role in influencing tipping elements and triggering tipping points in the Earth System. An example of a potential critical global tipping point, induced by climate extremes in an increasingly warmer climate, is Amazon rainforest dieback that could be driven by regional increases in droughts and exacerbated by fires, in addition to deforestation. A tipping element associated with the boreal forest might also be vulnerable to heat, drought and fire. An oceanic example is the potential collapse of the Atlantic meridional overturning circulation due to extreme variability in freshwater inputs, while marine heatwaves and high acidity extremes can lead to coral reef collapse. Extreme heat events may furthermore play an important role in ice sheet, glacier and permafrost stability. Regional severe extreme events could also lead to tipping in ecosystems, as well as in human systems, in response to climate drivers. However, substantial scientific uncertainty remains on mechanistic links between extreme events and tipping points. Earth observations are of high relevance to evaluate and constrain those links between extreme events and tipping elements, by determining conditions leading to delayed recovery with a potential for tipping in the atmosphere, on land, in vegetation, and in the ocean. In the subsurface ocean, there is a lack of consistent, synoptic and high frequency observations of changes in both ocean physics and biogeochemistry. This review article shows the importance of considering the interface between extreme events and tipping points, two topics usually addressed in isolation, and the need for continued monitoring to observe early warning signs and to evaluate Earth system response to extreme events as well as improving model skill in simulating extremes, compound extremes and tipping elements.

Aging, ROS, and cellular senescence: a trilogy in the progression of liver fibrosis.

Ageing is an inevitable and multifaceted biological process that impacts a wide range of cellular and molecular mechanisms, leading to the development of various diseases, such as liver fibrosis. Liver fibrosis progresses to cirrhosis, which is an advanced form due to high amounts of extracellular matrix and restoration of normal liver structure with failure to repair damaged tissue and cells, marking the end of liver function and total liver failure, ultimately death. The most important factors are reactive oxygen species (ROS) and cellular senescence. Oxidative stress is defined as an impairment by ROS, which are by-products of the mitochondrial electron transport chain and other key molecular pathways that induce cell damage and can activate cellular senescence pathways. Cellular senescence is characterized by pro-inflammatory cytokines, growth factors, and proteases secreted by senescent cells, collectively known as the senescence-associated secretory phenotype (SASP). The presence of senescent cells, which disrupt tissue architecture and function and increase senescent cell production in liver tissues, contributes to fibrogenesis. Hepatic stellate cells (HSCs) are activated in response to chronic liver injury, oxidative stress, and senescence signals that drive excessive production and deposition of extracellular matrix. This review article aims to provide a comprehensive overview of the pathogenic role of ROS and cellular senescence in the aging liver and their contribution to fibrosis.
