Abstract

The weightless environment during spaceflight induces site-specific bone loss. The 30-day Bion-M1 mission offered a unique opportunity to characterize the skeletal changes after spaceflight and an 8-day recovery period in mature male C57/BL6 mice. In the femur metaphysis, spaceflight decreased the trabecular bone volume (−64% vs. Habitat Control), dramatically increased the bone resorption (+140% vs. Habitat Control) and induced marrow adiposity invasion. At the diaphysis, cortical thinning associated with periosteal resorption was observed. In the Flight animal group, the osteocyte lacunae displayed a reduced volume and a more spherical shape (synchrotron radiation analyses), and empty lacunae were highly increased (+344% vs. Habitat Control). Tissue-level mechanical cortical properties (i.e., hardness and modulus) were locally decreased by spaceflight, whereas the mineral characteristics and collagen maturity were unaffected. In the vertebrae, spaceflight decreased the overall bone volume and altered the modulus in the periphery of the trabecular struts. Despite normalized osteoclastic activity and an increased osteoblast number, bone recovery was not observed 8 days after landing. In conclusion, spaceflight induces osteocyte death, which may trigger bone resorption and result in bone mass and microstructural deterioration. Moreover, osteocyte cell death, lacunae mineralization and fatty marrow, which are hallmarks of ageing, may impede tissue maintenance and repair.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Osteoclasts maintain their ability to resorb bone in microgravity, in contrast to osteoblasts and osteocytes, which are adversely affected by microgravity.

    “In stark contrast to the devastating effects of microgravity on osteoblasts, whose cytoskeletons may implode do to the failure of microtubules and actin filaments [54,55], and osteocytes, which undergo apoptosis as early as three days into space flight [56], osteoclasts maintain their ability to resorb bone in microgravity.”

    From Osteoclasts and Microgravity (2020) · cites this paper as [56]

    The citation [56] is attached to the claim that osteocytes undergo apoptosis as early as three days into spaceflight. The Discussion reports increased empty osteocyte lacunae after a 30-day flight, suggesting osteocyte death, but does not establish apoptosis at three days. It also reports increased bone resorption, though that is not the part of the sentence specifically attached to [56]. (LLM, conf=0.87)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
