The effect of tactile and verbal guidance during scapulothoracic exercises: An EMG and kinematic investigation.

Background: Clinician-led training through tactile and verbal guidance to improve muscle activity and joint motion are a common but understudied focus of therapeutic interventions for shoulder pain. The purpose of this study was to determine if clinician guidance changes scapulothoracic muscle activity and kinematics compared to unguided shoulder exercises.

Methods: Eleven participants with shoulder pain were studied.

Surfactant protein D regulates airway function and allergic inflammation through modulation of macrophage function.

The lung collectin surfactant protein D (SP-D) is an important component of the innate immune response but is also believed to play a role in other regulatory aspects of immune and inflammatory responses within the lung. The role of SP-D in the development of allergen-induced airway inflammation and hyperresponsiveness (AHR) is not well defined. SP-D levels progressively increased up to 48 hours after allergen challenge of sensitized mice and then subsequently decreased.

Human surfactant protein D (SP-D) binds Mycoplasma pneumoniae by high affinity interactions with lipids.

Increasing evidence now identifies surfactant protein D (SP-D) as an important element of the innate immune system of the lung. In this study, we examined the interactions of rat and human SP-D with the human pathogen, Mycoplasma pneumoniae. Rat and human SP-D bound the organism with high affinity in a reaction that required Ca(2+) and was inhibited by EGTA.
