Sensors, Vol. 19, Pages 4059: Estimating Chlorophyll Content of Leafy Green Vegetables from Adaxial and Abaxial Reflectance Sensors doi: 10.3390/s19194059 Authors: Lu Bu Lu As a primary pigment of leafy green vegetables, chlorophyll plays a major role in indicating vegetable growth status. The application of hyperspectral remote sensing reflectance offers a quick and nondestructive method to estimate the chlorophyll content of vegetables. Reflectance of adaxial and abaxial leaf surfaces from three common leafy green vegetables: Pakchoi var. Shanghai Qing (Brassica chinensis L. var. Shanghai Qing), Chinese white cabbage (Brassica campestris L. ssp. Chinensis Makino var. communis Tsen et Lee), and Romaine lettuce (Lactuca sativa var longifoliaf. Lam) were measured to estimate the leaf chlorophyll content. Modeling based on spectral indices and the partial least squares regression (PLS) was tested using the reflectance data from the two surfaces (adaxial and abaxial) of leaves in the datasets of each individual vegetable and the three vegetables combined. The PLS regression model showed the highest accuracy in estimating leaf chlorophyll content of pakchoi var. Shanghai Qing (R2 = 0.809, RMSE = 62.44 mg m−2), Chinese white cabbage (R2 = 0.891, RMSE = 45.18 mg m−2) and Romaine lettuce (R2 = 0.834, RMSE = 38.58 mg m−2) individually as well as of the three vegetables combined (R2 = 0.811, RMSE = 55.59 mg m−2). The good predicta...
CLEVELAND - Two healthcare organizations are coming together to form a joint venture that will expand the boundaries of care through telehealth. Cleveland Clinic and American Well announced the joint venture named The Clinic, during the first day of the 2019 Medical Innovation Summit (MIS). Cleveland Clinic will offer up its expertise in virtual care and Boston-based American Well will contribute its digital health technology platform. The two companies are focused on leading the industry toward integrated, digital care delivery models that complement and are connected to traditional care settings. Executives from the orga...

Introduction:Prehospital pediatric endotracheal intubation has lower first-pass success rates compared to adult intubations and in general may not offer a survival benefit. Increasingly, emergency medical services (EMS) systems are deploying prehospital extraglottic airways (EGA) for primary pediatric airway management, yet little is known about their efficacy. We evaluated the impact of a pediatric prehospital airway management protocol change, inclusive of EGAs, on airway management and patient outcomes in children in cardiac arrest or respiratory failure.Methods: Using data from a large, metropolitan, fire-based EMS ser...
Industry players examined the intersection of sex, tech, health and pleasure at the Giant Health event in London last week.
This is the second partnership that Singapore-headquartered Doctor Anywhere has announced in Vietnam in a period of about two months.
CONCLUSIONS: Despite the slight increases in the 10-year observation period a stable trend cannot be assumed. However, this study might be useful as baseline for other studies on SDM implementation. PMID: 31629688 [PubMed - as supplied by publisher]

CONCLUSION: Ultrastructural changes in rat liver tissue in conditions of obstructive jaundice may be reversible after restoration of drainage. On the other hand, ultrastructural changes in renal tissue in cases of prolonged jaundice are irreversible even if the internal drainage is restored.
