- An exercise-induced improvement in isolated skeletal muscle contractility does not affect the performance-enhancing benefit of 70 µmol l−1 caffeine treatment
Summary: The performance-enhancing effect of caffeine is not improved following exercise training as shown by assessing the effects of 70 µmol l−1 caffeine on muscle isolated from trained and untrained mice.
- Increased capillary tortuosity and pericapillary basement membrane thinning in skeletal muscle of mice undergoing running wheel training
Summary: Capillaries in skeletal muscles of mice undergoing long-term running wheel training change in structure, making them better adapted to the higher energy requirements of the tissue.
- Repair of traumatized mammalian hair cells via sea anemone repair proteins
Highlighted Article: Specific proteins secreted by sea anemones following trauma of hair cells on their tentacles assist in the recovery of traumatized hair cells of the murine cochlea.
- The thermal dependence of Na+ flux in isolated liver cells from ectotherms and endotherms
Summary: Na+ flux rate across liver cell membranes is compared between mammals (endotherms) and a series of ectotherms with different normal operating body temperatures.
- Evidence for an audience effect in mice: male social partners alter the male vocal response to female cues
Highlighted Article: Mice modify their vocalizations in response to audiences, but not to simple social stimuli, constituting a novel paradigm for measuring the influence of social cues.
- Shiver me titin! Elucidating titin's role in shivering thermogenesis
Summary: Mice with a titin mutation have lower active muscle stiffness and lower shivering frequencies than predicted. Titin may provide the tuning of shivering frequency by affecting active muscle stiffness.
