Evidence for an association of serum microanalytes and myofascial pain syndrome.

Background: Myofascial Pain Syndrome (MPS) is a common pain disorder. Diagnostic criteria include physical findings which are often unreliable or not universally accepted. A precise biosignature may improve diagnosis and treatment effectiveness.

Behavioural responses to environmental hypercapnia in two eusocial species of African mole rats.

Damaraland and naked mole rat are eusocial mammals that live in crowded burrows in which CO is elevated. These species are thought to be highly tolerant of CO but their behavioural responses to hypercapnia are poorly understood. We hypothesized that Damaraland and naked mole rats would exhibit blunted behavioural responses to hypercapnia and predicted that their activity levels would be unaffected at low to moderate (2-5%) CO but increased at > 7% CO.
