Article Synopsis
  • The study investigates how joint movements affect the ability of cartilage to maintain fluid load support (FLS), challenging the idea that small involuntary movements are detrimental during prolonged inactivity.
  • Experiments were conducted using smooth glass spheres sliding against bovine cartilage samples under various loads and movement distances, revealing that even minimal movements (0.05 mm) can sustain non-zero FLS.
  • The results suggest that small movements like fidgeting can help maintain FLS, but the benefits decrease if the movement length is less than ten times the contact diameter, highlighting both the potential advantages and limitations of minor joint movements for long-term cartilage health.

Cyclic AMP (cAMP) is involved in many biological processes but little is known regarding its role in shaping immunity. Here we show that cAMP-PKA-CREB signaling (a pattern recognition receptor [PRR]-independent mechanism) regulates conventional type-2 Dendritic Cells (cDC2s) in mice and reprograms their Th17-inducing properties via repression of IRF4 and KLF4, transcription factors essential for cDC2-mediated Th2 induction. In mice, genetic loss of IRF4 phenocopies the effects of cAMP on Th17 induction and restoration of IRF4 prevents the cAMP effect.

The purpose of introducing sounds is to afford a comfortable acoustic environment and to design good soundscapes. This study aims at rating the preference of subjects for the introduced sounds suitable to the public spaces and also investigates the methodology to select the sounds by subjective and objective procedures. Seventeen kinds of the introduced sounds were evaluated with nine adjectives in the presence of visual location information.

Tissue distribution studies of [18F]haloperidol and [82Br]bromperidol, two potent neuroleptic drugs, were performed in rats by serial sacrifice. The usefulness of external scintigraphy in obtaining tissue distribution data in large animals is demonstrated by the tissue distribution of [18F]haloperidol in rhesus monkeys. Both serial sacrifice and external scintigraphic studies demonstrated that uptake of the two drugs after intravenous administration into their target organ, the brain, was very fast and that the ratio of brain to blood levels was high throughout the 2-hr observation.
