Published: August 2021

AbstractMeasurements of life-history traits can reflect an organism’s response to environment. In wave-dominated rocky intertidal ecosystems, obtaining in-situ measurements of key grazing invertebrates are constrained by extreme conditions. Recent research demonstrates mollusc shells to be high-resolution sea-surface temperature proxies, as well as archival growth records. However, no prior molluscan climate proxy or life-history reconstruction has been demonstrated for the tropical rocky intertidal environment—a zone influenced by warmer waters, mixed tides, trade-wind patterns, and wave-action. Here, we show near-daily, spatiotemporal oxygen isotope signatures from the tropical rocky intertidal environment by coupling secondary ion mass spectrometry analysis of oxygen isotopes with the sclerochronology of an endemic Hawaiian intertidal limpet Cellana sandwicensis, that is a significant biocultural resource harvested for consumption. We also develop a method for reliable interpretation of seasonal growth patterns and longevity in limpets. This study provides a robust approach to explore tropical intertidal climatology and molluscan life-history.
The co‐effect of microstructures and mucus on the adhesion of abalone from a mechanical perspective
Authors: Li Jing , Ma Chuandong , Liu Jun , Dong Xiangwei , Liu Jianlin 
Published: August 2021

AbstractReliable and reversible adhesion underwater is challenging due to the water molecules and weak layers of contaminants at the contact interface, which requires to deepen the understanding of wet adhesion of biological surfaces. Herein, the co‐effect of microstructures and mucus of abalone foot on wet adhesion is investigated from both experimental and theoretical perspectives. The morphologies, adhesion force and coefficient of friction indicate that the mucus in adhesion zone is crucial for successful attachment of abalone based on capillary forces and viscous forces, and the mucus in non‐adhesion zone with lower adhesion force and friction coefficient may behave as a lubricant for the locomotion. The theoretical calculation manifests that the microstructures may help abalone to form multiple liquid bridges with the secreted mucus, and significantly increase the wet adhesion force of abalone. These findings will bring profound views into the underlying mechanisms of biological surface adhesion.
Matrix‐based method for solving decision domains of neighbourhood multigranulation decision‐theoretic rough sets

Published: August 2021

AbstractIt is more and more important to analyse and process complex data for gaining more valuable knowledge and making more accurate decisions. The multigranulation decision theory based on conditional probability and cost loss has the advantage of processing decision‐making problems from multi‐levels and multi‐angles, and the neighbourhood rough set model (NRS) can facilitate the analysis and processing of numerical or mixed type data, and can address the limitation of multigranulation decision‐theoretic rough sets (MG‐DTRS), which is not easy to cope with complex data. Based on the in‐depth study of hybrid‐valued decision systems and MG‐DTRS models, this study analysed neighbourhood MG‐DTRS (NMG‐DTRS) deeply by fusing MG‐DTRS and NRS; a matrix‐based approach for approximation sets of NMG‐DTRS model was proposed on the basis of the matrix representations of concepts; the positive, boundary and negative domains were constructed from the matrix perspective, and the concept of positive decision recognition rate was introduced. Furthermore, the authors explored the related properties of NMG‐DTRS model, and designed and described the corresponding solving algorithms in detail. Finally, some experimental results that were employed not only verified the effectiveness and feasibility of the proposed algorithm, but also showed the relationship between the decision recognition rate and the granularity and threshold.
Fine structure in the luminosity function in young stellar populations with Gaia DR2

Published: August 2021

Context. A pioneering study showed that the fine structure in the luminosity function (LF) of young star clusters contains information about the evolutionary stage (age) and composition of the stellar population. The notable features include the H-peak, which is the result of the onset of hydrogen burning turning pre-main sequence stars into main sequence stars. The feature moves toward the faint end of the LF, and eventually disappears as the population evolves. Another detectable feature is the Wielen dip, a dip at MV ≃ 7 mag in the LF first identified in 1974 for stars in the solar environment. Later studies also identified this feature in the LF of star clusters. The Wielen dip is caused by the increased importance of H− opacity in a certain range of low-mass stars.
Aims. We studied the detailed structure in the luminosity function using the data from Gaia DR2 and PARSEC stellar evolution models with the aim to further our understanding of young stellar populations.
Methods. We analyzed the astrometric properties of stars in the solar neighborhood (< 20 pc) and in various relatively nearby (< 400 pc) young (< 50 Myr) open clusters and OB associations, and compare the features in the luminosity function with those generated by PARSEC models.
Results. The Wielen dip is confirmed in the LF of all the populations, including the solar neighborhood, at MG ≃ 7 mag. The H-peak is present in the LF of the field stars in the solar neighborhood. It likely signals that the population is mixed with a significant number of stars younger than 100 Myr. The H-peak is found in the LF of young open clusters and OB associations, and its location varies with age. The PARSEC evolutionary models predict that the H-peak moves from ∼ − 1 mag towards ∼ + 6 mag in MG for populations with ages increasing from 1 to ∼70 Myr. Our observations with Gaia DR2 confirm the evolution of the H-peak from ∼5 Myr up to ∼47 Myr. We provide a calibration function between MG and age that works in the age domain between 1 and 30 Myr.
Conclusions. The fine structure in the luminosity function in young stellar populations can be used to estimate their age.

Aims.We analyzed the surface of Vesta at visible wavelengths, using the data of the Visible and InfraRed mapping spectrometer (VIR) on board the Dawn spacecraft. We mapped the variations of various spectral parameters on the entire surface of the asteroid, and also derived a map of the lithology.Methods.We took advantage of the recent corrected VIR visible data to map the radiance factor at 550 nm, three color composites, two spectral slopes, and a band area parameter relative to the 930 nm crystal field signature in pyroxene. Using the howardite-eucrite-diogenite meteorites data as a reference, we derived the lithology of Vesta using the variations of the 930 and 506 nm (spin-forbidden) band centers observed in the VIR dataset.Results.Our spectral parameters highlight a significant spectral diversity at the surface of Vesta. This diversity is mainly evidenced by impact craters and illustrates the heterogeneous subsurface and upper crust of Vesta. Impact craters also participate directly in this spectral diversity by bringing dark exogenous material to an almost entire hemisphere. Our derived lithology agrees with previous results obtained using a combination of infrared and visible data. We therefore demonstrate that it is possible to obtain crucial mineralogical information from visible wavelengths alone. In addition to the 506 nm band, we identified the 550 nm spin-forbidden one. As reported by a laboratory study for synthetic pyroxenes, we also do not observe any shift of the band center of this feature across the surface of Vesta, and thus across different mineralogies, preventing use of the 550 nm spin-forbidden band for the lithology derivation. Finally, the largest previously identified olivine rich-spot shows a peculiar behavior in two color composites but not in the other spectral parameters.
A hybrid system for monitoring and automated recovery at the Glasgow Tier-2 cluster

Published: August 2021

We have deployed a central monitoring and logging system based on Prometheus, Loki and Grafana that collects, aggregates and displays metrics and logs from the Tier-2 ScotGrid cluster at Glasgow. Bespoke dashboards built on Prometheus metrics give a quick overview of cluster performance and make it easy to identify issues. Logs from all nodes and services are collected to a central Loki server and retained over time. This integrated system provides a full overview of the cluster’s health and has become an essential tool for daily maintenance and in the investigation of any issue.
The system includes an automated alerting application that parses metrics and logs and can send notifications when specified conditions are met, and as a further step toward automation, can also perform simple recovery actions based on well known issues and their encoded solutions. The general purpose is to create a more resilient Tier-2 cluster where human intervention is kept to a minimum. Given the funding constraints experienced by many academic research institutions, this promises to free staff from routine tasks, allowing them to address their expertise to more interesting problems.
In this paper, we describe the tools and set-up of the existing monitoring system, the automated recovery methods implemented so far, and the plan for further automation.

Published: August 2021

The alignment of the Belle II tracking system, composed of a pixel and strip vertex detectors and central drift chamber, is described by approximately sixty thousand parameters; from local alignment of sensors and wires to relative global alignment of the sub-detectors.In the next data reprocessing, scheduled since Spring 2021, we aim to determine all parameters in a simultaneous fit by Millepede II, where recent developments allow to achieve a direct solution of the full problem in about one hour and make it practically feasible for regular detector alignment.The tracking detectors and the alignment technique are described and the alignment strategy is discussed in the context of studies on simulations and experience obtained from recorded data. Preliminary results and further refinements based on studies of real Belle II data are presented.
Effekte von hochintensivem Intervalltraining (HIIT) auf Body-Mass-Index (BMI) und Körperfettanteil von übergewichtigen und adipösen Kindern – eine systematische Übersichtsarbeit
Authors: Sitzmann Lennert , Akrama Gaith , Baumann Christian 
Published: August 2021

Zusammenfassung
Hintergrund Mehr als 340 Millionen Kinder gelten weltweit als übergewichtig oder adipös, ihre Anzahl nahm in den letzten Jahren – auch durch die Coronapandemie – erheblich zu. Eine alternative Behandlung zur Reduzierung des Übergewichts, die in den Empfehlungen bisher keine große Beachtung findet, stellt das sogenannte hochintensive Intervalltraining (HIIT) dar.
Ziel Darstellung der Wirksamkeit von hochintensivem Intervalltraining auf den BMI und Körperfettanteil übergewichtiger und adipöser Kinder im Alter von 6–13 Jahren.
Methode Die Erstellung der systematischen Übersichtsarbeit orientierte sich an den PRISMA-Guidelines. Für die Literaturrecherche wurden die Datenbanken MEDLINE, Cochrane Library, CINAHL, Embase, Sports Medicine & Education Index und Web of Science nach Studien mit hochintensivem Intervalltraining für übergewichtige und adipöse Kinder durchsucht. Die Bewertung der methodischen Studienqualität erfolgte mittels PEDro-Skala, MINORS und Risk of Bias. Die Berichtsqualität wurde anhand von CONSORT und TREND bewertet.
Ergebnisse Es wurden 6 randomisierte kontrollierte Studien und 2 kontrollierte klinische Studien mit 479 HIIT-Teilnehmenden betrachtet. Diese zeigten, dass hochintensives Intervalltraining positive Auswirkungen auf den BMI und Körperfettanteil übergewichtiger und adipöser Kinder hat.
Schlussfolgerung Hochintensives Intervalltraining ist eine kinderfreundliche und zugleich effektive Alternative zur Behandlung von übergewichtigen und adipösen Kindern. Weitere klinische Studien sind erforderlich, um die Ergebnisse zu bekräftigen.
Amendments suggested for zoo medical research strategies with focus on the D-A-CH region
Authors: Sipos Wolfgang , Lutonsky Christiane 
Published: August 2021

Abstract
Objective Scientific exploration of zoo animals is one of the main missions of modern zoos. As scientific achievements are best reflected within scientific literature, we screened appropriate literature search outcomes from the 5 highest ranked zoos in the D-A-CH region (Germany-Austria-Switzerland) in order to deduce suggestions for optimizations of future research strategies.
Material and methods Literature search was done by entering ”Zoo Vienna”, “Tiergarten Schönbrunn”, “Zoo Berlin”, “Tiergarten Berlin”, “Tierpark Hellabrunn”, “Tierpark Hagenbeck”, and “Zoo Zurich” on PubMed and Scopus for the period 2000–2020. These 5 European zoos were chosen due to their broad public recognition and international importance. Inclusion criterion for the literature list was the description/mentioning of analysed animals or samples with a clear affiliation to the respective zoo in the materials and methods or acknowledgements sections. Search hits were then allocated to the following 7 areas: animal nutrition, biology, ethology, infectiology, reproduction, phylogenetics, and clinical medicine. Also, portions of higher animal taxa (and species, if appropriate) were recorded.
Results and conclusions A total of 142 papers has been published. Mammals, especially large ones, were clearly over-represented in literature with 2 thirds of analysed papers dealing with them. Sauropsids (birds and reptiles) were treated in 28 % and non-amniotic vertebrates (amphibians and fish) as well as invertebrates in only 3 % each. This apportionment is in no relation to the species numbers of the respective higher animal taxa. The predominating research areas (covered by approximately 75 % of papers) were ethological studies, followed by papers on infectious diseases, and finally papers on biology with morphological, physiological, and molecular biological themes. Research on reproductive biology/medicine, which is considered to be of tremendous importance for the establishment of ex-situ populations and thus for the conservation of endangered species, has been covered by only 6 % of papers. Future research should more intensely keep an eye on that discipline, especially in non-mammalian vertebrates.
Long-COVID – Eine Mitochondriopathie?
Authors: Gröber Uwe 
Published: August 2021

ZusammenfassungIn Deutschland steigt die Impfquote wöchentlich, so dass ein Ende der kritischen Phase der Coronavirus-Pandemie absehbar scheint. Nach Schätzungen der WHO leidet etwa jeder 10. COVID-19-Patient noch 12 Wochen nach der Infektion unter lang anhaltenden Beschwerden, auch wenn er nicht in der Klinik behandelt werden musste. Das SARS-CoV-2-Virus kann zentrale mitochondriale Funktionen beeinflussen und damit eine Störung der angeborenen Immunität sowie der antiviralen Signalwege und mitochondrialen Dynamik auslösen. Dies spielt aller Wahrscheinlichkeit nach eine zentrale Rolle in der Pathogenese von COVID-19 als auch von Long-COVID. Der Beitrag geht auf die spezifische Zellinfektion sowie auf neue antivirale Strategien ein.

AbstractObjective Canine atopic dermatitis (CAD) is a common skin disease in dogs. Prior studies were able to determine beneficial effects of essential fatty acids (EFA) on the clinical signs of CAD. The aim of this study was set to evaluate the effects of a newly designed, EFA-enriched diet on the clinical signs of CAD compared to another EFA-enriched diet.Materials and methods In this prospective, randomized, double-blinded study, 31 privately owned dogs with atopic dermatitis received either the control diet (diet A, Hill’s Prescription Diet™ d/d™ Salmon & Rice, n = 17) or the test diet (diet B, Veterinary HPM™ Dermatology Support D1, Virbac, n = 14) for 12 weeks. At the beginning of the study as well as after 4, 8 and 12 weeks, skin lesions and pruritus were evaluated via validated scores and the administered medication was documented. At the same time, the dogs’ coat quality was evaluated via a distinct scoring system. In both groups, a total of 7 dogs each completed the entire study.Results After 12 weeks, there was a mild improvement in lesion scores, pruritus and coat quality with both diets.Clinical relevance In this study, both diets improved the patients’ skin lesions pruritus and coat quality.

Abstract
Aims To examine the association of frozen shoulder (FS) with demographic
and diabetes-related outcomes in individuals with type 1 (T1D) or type 2 (T2D)
diabetes aged ≥30 years.
Materials and methods Multivariable logistic regression models, adjusted
for demographics were used to calculate the proportion of FS in association with
age, gender, diabetes duration, body mass index (BMI), haemoglobin A1C (HbA1c)
and diabetes treatment.
Results The unadjusted percentage of FS was higher in T1D compared to T2D
(0.22% vs. 0.06%). In T1D, adjusted regression models revealed
higher prevalence of FS in women than men (0.26 [0.20–0.34] %
vs. 0.15 [0.11–0.21] %, p=0.010). No significant
relationship of age and BMI with FS was found in both diabetes types. Longer
diabetes duration was associated with a higher proportion of FS in T1D
(p<0.001) and T2D (p=0.004). In T1D, HbA1c
>7% was related to a higher proportion of FS compared to HbA1c
≤7% (0.25 [0.19–0.32] vs. 0.12 [0.08–0.20]
%, p=0.007), while an inverse relationship was found in
T2D (HbA1c ≤7%: 0.08 [0.07–0.10] vs. HbA1c
>7%: 0.05 [0.04–0.06] %,
p=0.001).
Conclusions Different associations of FS with gender and HbA1c were
observed for T1D and T2D; however, longer diabetes duration increases the risk
for FS independent of diabetes type. Musculoskeletal diseases are still
underreported in individuals with diabetes and awareness should be raised for FS
as a specific diabetes complication.
Adipositas beim Hund – ein Überblick zu den Ursach
Authors: Ronja Nitsch , Kölle Petra 
Published: August 2021

ZusammenfassungÜbergewicht stellt nicht nur bei Menschen, sondern auch bei Haustieren ein schwerwiegendes gesundheitliches Problem dar. Dieses wird jedoch durch den Besitzer häufig nicht als solches erkannt. Aktuelle Studien gehen davon aus, dass bis zu 60 % der Haushunde übergewichtig oder krankhaft adipös sind. Vielseitige Ursachen kommen in Betracht. Nicht nur das Fütterungsmanagement, sondern auch die Genetik, das Alter und Geschlecht, bestimmte Primärerkrankungen, iatrogene Ursachen und die Besitzer-Haustier-Beziehung können zur Erhöhung des Erkrankungsrisikos beitragen. Um Adipositas qualifiziert zu behandeln oder idealerweise die Erkrankung gänzlich zu verhindern, ist das detaillierte Wissen über die verschiedenen Risikofaktoren essenziell. Der Artikel bietet eine Übersicht zu den bisher bekannten Ursachen.
PEG-Supported Hypervalent Iodine Reagent for Sulfonamide Synthesis
Authors: Marques M. Manuel B. , Macara João , Poeira Diogo L. , Coelho Jaime A. S. 
Published: August 2021

AbstractA reusable and recoverable PEG-supported hypervalent iodine reagent is reported. This hypervalent iodine reagent, immobilized in a soluble polymer support, was easily prepared in six steps from PEG-OH 2000. This reagent was successfully applied in a mild sulfonamide synthesis using a sulfinate salt and an amine in up to 95% yield. The use of the soluble polymer allowed a facile workup procedure and reaction monitoring, by simple precipitation and filtration of the reagent, with an easy recovery and subsequent re-oxidation and reuse. This approach greatly improves the sustainability of this sulfonamide synthesis method, avoiding frequent preparation of reagents and generation of waste during the purification steps.
Donor Site Morbidity after Lumbar Artery Perforator Flap Breast Reconstruction
Authors: Opsomer Dries , Vyncke Tom , Ryx Michelle , Van Landuyt Koenraad , Blondeel Phillip , Stillaert Filip 
Published: August 2021

AbstractBackground The lumbar artery perforator flap is a second-choice flap in autologous breast reconstruction whenever a deep inferior epigastric artery perforator (DIEP) flap is not possible. Ideal candidates are pear-shaped women who do not have enough bulk on the abdomen or thighs. Patient-reported “satisfaction with breasts” is excellent but we were curious about the donor site morbidity.Methods We performed a retrospective study of all lumbar flap breast reconstructions performed between 2010 and 2019. Patients were invited by e-mail and telephone to take part in a BREAST-Q survey.Results One hundred fifty-four flaps were performed in 110 patients. Sixty-three patients filled out the BREAST-Q questionnaire. The most frequently observed donor site complications are seroma (35.1%), dehiscence (8.4%), and hematoma (3.2%). Correction of the donor site scar was performed in 31.8% of patients, lipofilling of the donor flank in 5.2%, and liposuction of the contralateral flank in 18.3% of patients. Body mass index (BMI) was the only significant risk factor for donor site complications. Patient-reported “satisfaction with donor site appearance” was good but significantly lower for primary reconstructions compared with secondary and tertiary procedures. Flap weight significantly influences patient-reported “physical wellbeing of the donor site.” Ninety-seven percent of patients would recommend the surgery to someone in a similar position and would do it all over.Conclusion The lumbar artery perforator flap is a good alternative for breast reconstruction in selected patients. The donor site issues consist mainly of seromas, prolonged discomfort, and a scar that might be noticeable to others, but patient-reported satisfaction is very high.
