22. Maritime traffic alters distribution of the harbour porpoise in the North Sea.

Abstract

The North Sea is one of the most industrialised marine regions globally. We integrated cetacean-dedicated aerial surveys (2015–2022) with environmental covariates and ship positions from the Automatic Identification System (AIS) to investigate the disturbance radius and duration on harbour porpoise distribution. This study is based on 81,511 km of line-transect survey effort, during which 6511 harbour porpoise groups (8597 individuals) were sighted. Several proxies for ship disturbance were compared, identifying those best explaining the observed distribution. Better model performance was achieved by integrating maritime traffic, with frequent traffic representing the most significant disturbance to harbour porpoise distribution. Porpoises avoided areas frequented by numerous vessels up to distances of 9 km. The number of ships and average approach distance over time improved model performance, while reasons for the lower performance of predicted ship sound levels remain unclear. This study demonstrates the short-term effects of maritime traffic on harbour porpoise distribution. [Display omitted] • Cetacean survey data (2015–2022) in the North Sea were combined with vessel positions. • Effects of vessel presence on harbour porpoise distribution were investigated. • Spatial avoidance was detected, particularly in areas with heavy or frequent traffic. • Best predictors were the number of vessels and average approach distance over time. • This broad-scale study shows short-term effects over 9 km on porpoise distribution.

27. Foot and Ankle Surgical Incision Closure With Three Different Materials.

Author

Abstract

There is no clear recommendation for wound closure material in foot and ankle surgery. Thus, we hypothesized that there was no difference in clinical outcomes among 3 suture materials, namely, absorbable sutures, nonabsorbable sutures, and metallic staples. This study compared the 3 materials for wound closure in foot and ankle surgery. In this prospective randomized study, 124 patients were randomly divided into the nonabsorbable suture group, absorbable suture group, and staple group. ASEPSIS score, Hollander Wound Evaluation Scale, and numerical rating scale (regarding pain and satisfaction) were collected at first dressing changes, suture removal, and 6 weeks after surgery. Suture time and incision length were recorded. No significant differences were detected for the ASEPSIS and Hollander Wound Evaluation Scale scores. There was significantly more pain after 6 weeks in the nonabsorbable suture group. The closure time (13 s/cm) with staples was significantly lower in the nonabsorbable suture group than in the other groups. Regardless of wound closure material, male sex and obesity appeared to be associated with a higher risk for the occurrence of wound complications. The 3 suture materials showed no significant differences regarding the frequency of wound complications. Staples and absorbable sutures should therefore be considered in the repertoire of suture materials used in foot and ankle surgery. [ABSTRACT FROM AUTHOR]

39. The structure and mechanical properties of articular cartilage are highly resilient towards transient dehydration.

Abstract

Articular cartilage is a mechanically highly challenged material with very limited regenerative ability. In contrast to elastic cartilage, articular cartilage is exposed to recurring partial dehydration owing to ongoing compression but maintains its functionality over decades. To extend our current understanding of the material properties of articular cartilage, specifically the interaction between the fluid and solid phase, we here analyze the reversibility of tissue dehydration. We perform an artificial dehydration that extends beyond naturally occurring levels and quantify material recovery as a function of the ionic strength of the rehydration buffer. Mechanical (indentation, compression, shear, and friction) measurements are used to evaluate the influence of de- and rehydration on the viscoelastic properties of cartilage. The structure and composition of native and de/rehydrated cartilage are analyzed using histology, scanning electron microscopy, and atomic force microscopy along with a 1,9-dimethylmethylene blue (DMMB) assay. A broad range of mechanical and structural properties of cartilage can be restored after de- and rehydration provided that a physiological salt solution is used for rehydration. We detect only minor alterations in the microarchitecture of rehydrated cartilage in the superficial zone and find that these alterations do not interfere with the viscoelastic and tribological properties of the tissue. Statement of Significance We here demonstrate the sturdiness of articular cartilage towards changes in fluid content and show that articular cartilage recovers a broad range of its material properties after dehydration. We analyze the reversibility of tissue dehydration to extend our current understanding of how the material properties of cartilage are established, focusing on the interaction between the fluid and solid phase. Our findings suggest that the high resilience of the tissue minimizes the risk of irreversible material failure and thus compensates, at least in part, its poor regenerative abilities. Tissue engineering approaches should thus not only reproduce the correct tissue mechanics but also its pronounced sturdiness to guarantee a similar longevity. [ABSTRACT FROM AUTHOR]

40. DISTRIBUTION OF SEABIRDS AND MARINE MAMMALS.

Author

de Bolsée, Oria Jamar, Nachtsheim, Dominik, and Joiris, Claude

Abstract

The article discusses a research programme which is part of a long-term study led by the Laboratory for Polar Ecology on the at-sea distribution of seabirds and marine mammals in the Arctic and Antarctic polar regions. Topics include the objective of improving the knowledge on distribution and densities of higher tropic levels due to influencing environmental factors. Also mentioned is integration of programme data into a time series since 1973 to detect changes in the animal distribution.

50. Comment: Fisher Lecture: Dimension Reduction in Regression.

Abstract

The author comments on the paper "Fisher Lecture: Dimension Reduction in Regression," by R. D. Cook. The paper develops a theoretical foundation for exploring principal components and other dimension reduction methods in a regression context. It reports to a model, via the inverse regression of predictors, to analyze reduction in a forward regression problem. It also allows extension to mixtures of predictors. The role of predictor screening and a connection with the supervised principal components method are explored.
