Current levels vs. longitudinal changes: A 7-year study on physical function, brain structure and cognition in older adults

Eline Baad-Hansen, Naiara Demnitz, Anne Theil Gates, Michael Kjær et autres

Background Declines in physical function, brain structure, and cognition are common effects of aging in later life. Here we investigate whether changes in physical function and gray matter volumes over a seven-year span predict cognitive performance in older adults. Methods We analyzed …

Physical activity and other modifiers of extracellular matrix dynamics in healthy and diseased tendon tissue: focus on in vivo techniques

Benjamin Rosborg, Michael Kjær, Ann Damgaard

Tendons have traditionally been considered largely metabolically inert, and little research has focused on tendon matrix dynamics. In the past few decades, the study of tendon extracellular matrix dynamics in humans has progressed immensely as new methods have been used to investigate …

Spatial proteomics of skeletal muscle using thin cryosections reveals metabolic adaptation at the muscle-tendon transition zone

Luisa Schmidt, Michael Saynisch, Christian Hoegsbjerg, Andreas C. Schmidt et autres

Morphological studies of skeletal muscle tissue provide insights into the architecture of muscle fibers, the surrounding cells, and the extracellular matrix (ECM). However, a spatial proteomics analysis of the skeletal muscle including the muscle-tendon transition zone is lacking. Here, we prepare cryotome …

Exercise entrainment of musculoskeletal connective tissue clocks

Danielle Steffen, Michael Kjær, Ching‐Yan Chloé Yeung

The musculoskeletal system, crucial for movement and support, relies on the delicate balance of connective tissue homeostasis. Maintaining this equilibrium is essential for tissue health and function. There has been increasing evidence in the past decade that shows the circadian clock as …

The mitochondrial mRNA stabilizing protein, SLIRP, regulates skeletal muscle mitochondrial structure and respiration by exercise-recoverable mechanisms

Tang Cam Phung Pham, Steffen Henning Raun, Essi Havula, Carlos Henríquez‐Olguín et autres

Summary and graphical abstract Decline in mitochondrial function associates with decreased muscle mass and strength in multiple conditions, including sarcopenia and type 2 diabetes. Optimal treatment could include improving mitochondrial function, however, there are limited and equivocal data regarding the molecular cues …

Achilles Tendon Tissue Turnover Before and Immediately After an Acute Rupture

Allan Cramer, Grith Westergaard Højfeldt, Peter Schjerling, Jakob Agergaard et autres

Background: An Achilles tendon rupture (ATR) is a frequent injury and results in the activation of tendon cells and collagen expression, but it is unknown to what extent turnover of the tendon matrix is altered before or after a rupture. Purpose/Hypothesis: The …

CAGE22-3 Cruise Report: EMAN7 cruise

Bénédicte Ferré, Giuliana Panieri, Claudio Argentino, Muhammed Fatih Sert et autres

The cruise mainly focused on two areas in the Hola Trough: at node 7 where methane seeps have been mapped, and further north (node 1) where are located cold coral reefs. The aim of the cruise was to characterize the seafloor and …

Temaintroduktion: Kunsthistoriefaget i dag. Samtidskunst, selvransagelse og åbne faggrænser

Karen Benedicte Busk-Jepsen, Kristian Handberg, Michael Kjær

Dette temanummer af Periskop drejer sig om, hvordan kunsthistoriefaget praktiseres anno 2022 – især med hensyn til den akademiske disciplin i dansk sammenhæng, som den udfoldes på universiteterne og i museumsregi. Vi har valgt at spørge bredt ud til, hvilke erfaringer der …
