BACKGROUND Long-term treatment with supplemental oxygen has unknown efficacy in patients with stable chronic obstructive pulmonary disease (COPD) and resting or exercise-induced moderate desaturation. METHODS We originally designed the trial to test whether long-term treatment with supplemental oxygen would result in a longer time to death than no use of supplemental oxygen among patients who...

A randomized, double-blind trial was conducted to compare the efficacy of 4% articaine with 1:100,000 epinephrine and 2% lidocaine with 1:100,000 epinephrine when used as a supplemental anesthetic. Forty-eight patients with irreversible pulpitis requiring supplemental buccal infiltration for endodontic therapy were given either 4% articaine with 1:100,000 epinephrine or 2% lidocaine with 1:100,...

resistance of microencapsulated fish oil (mfo) in the rumen and its effects on fermentability of nutrients in the rumen was studied in 3 experiments. the key parameter in these studies was the amount of oil released from the microcapsules and their effects on gas production and rumen degradability in comparison with unprotected fish oil (fo). in the first experiment the effect of rumen and abom...

We developed a method to evaluate the activity of Na+–Ca2+ exchanger (NCX) and sarco-endoplasmic reticulum Ca2+-ATPase (SERCA) with fluorescence microscopy in mouse ventricular cardiomyocytes. In non-beating cardiomyocytes, α-adrenoceptor stimulation by phenylephrine caused decrease cytoplasmic Ca2+ concentration, which was inhibited SEA0400, an NCX inhibitor, but not cyclopiazonic acid, SERCA ...

This proof is adapted from Dassios and Zhao (2013) to our setting. We first note that the intensity λ t increases by Y j at jump time T j. That is, the right limit λ T + j is equal to the left limit λ T − j plus Y j. Thus, after the j-th jump, the intensity λ t would follow λ t = λ T + j − a e −δ(t−Tj) + a, T j ≤ t < T j + S j+1 , where T j and λ T + j are observed at the j-th jump. Here S j+1 ...

For many people, the corner store remains the main grocer, or the only source of sustenance in minority communities. This study examined the distribution of corner stores as a future reference point to provide healthy food access to predominantly African American communities that lack full service grocery stores. Business data was obtained from respective county by use of Standard Industrial Co...

INTRODUCTION Our objectives were to (a) identify rates of food insecurity among patients seen in a pediatric weight management clinic and (b) test a pilot intervention to address food insecurity in the identified patients. METHODS All new patients seen in the clinic were screened for food insecurity and Supplemental Nutrition Assistance Program (SNAP) benefit status. Families with food insecu...
