Managing dyspnea in patients with advanced chronic obstructive pulmonary disease: a Canadian Thoracic Society clinical practice guideline.

Dyspnea is a cardinal symptom of chronic obstructive pulmonary disease (COPD), and its severity and magnitude increases as the disease progresses, leading to significant disability and a negative effect on quality of life. Refractory dyspnea is a common and difficult symptom to treat in patients with advanced COPD. There are many questions concerning optimal management and, specifically, whether various therapies are effective in this setting.

Women with postpartum depression: "my husband" stories.

Background: The research on Postpartum Depression (PPD) to date suggests that there is a knowledge gap regarding women's perception of their partners' role as carer and care activities they perform. Therefore, the purpose of this study was to describe women's understanding of their partners' or husbands' involvement in the midst of PPD.

Methods: This study used interview data from a larger study of northern and rural Ontario women's stories of help-seeking for PPD.

An energy supply network of nutrient absorption coordinated by calcium and T1R taste receptors in rat small intestine.

T1R taste receptors are present throughout the gastrointestinal tract. Glucose absorption comprises active absorption via SGLT1 and facilitated absorption via GLUT2 in the apical membrane. Trafficking of apical GLUT2 is rapidly up-regulated by glucose and artificial sweeteners, which act through T1R2 + T1R3/alpha-gustducin to activate PLC beta2 and PKC betaII.
