Abstract

Mitochondrial respiratory systems have been screened in 63 orthopaedic patients of age ranging between 17 and 91 years. The results show a statistically significant definite decrease with ageing of mitochondrial respiratory activity with pyruvate plus malate, succinate and ascorbate plus TMPD. This pattern is associated with an equally significant decrease with age of the enzymatic activity of complex I, II and IV. No significant decrease with age is, on the contrary, observed in the mitochondrial content of cytochromes a+a3, and c+c1. Preliminary Western blot analysis indicates an altered polypeptide pattern in cytochrome c oxidase. This study provides evidence for a decline with age of mitochondrial respiratory activity in human skeletal muscle, affecting complex I, II and IV.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • The majority of prior studies describing lower mitochondrial oxidative capacity with aging have not considered important covariates such as cardiorespiratory fitness and BMI.

    “There have been many reports describing lower mitochondrial oxidative capacity with aging (6-11), however, the majority have not considered important covariates such as cardiorespiratory fitness (8,9) and BMI (7,8,11).”
  • Most studies of mitochondrial respiration have not considered important covariates such as participant physical activity levels, adiposity, and fiber type percentage, which could confound the relationship between mitochondrial capacity and age.

    “Moreover, most studies of mitochondrial respiration have not considered important covariates such as participant physical activity levels (9), adiposity (11), and fiber type percentage, which could confound the relationship between mitochondrial capacity and age (10,12,18,19).”
  • Many prior studies of mitochondrial respiration have used isolated mitochondria.

    “Many have also used isolated mitochondria (6,9,11).”
  • Several prior investigations were performed in isolated mitochondria, which has been shown to exaggerate the observed deficit in mitochondrial function compared to measurements conducted on permeabilized myofibers.

    “Furthermore, several of these investigations were performed in isolated mitochondria (6,9,11), which has been shown to exaggerate the observed deficit in mitochondrial function, when compared to measurements conducted on permeabilized myofibers (17).”

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.
