Managed honeybees and South American bumblebees exhibit complementary foraging patterns in highbush blueberry.

Despite Apis mellifera being the most widely managed pollinator to enhance crop production, they are not the most suitable species for highbush blueberries, which possess restrictive floral morphology and require buzz-pollination. Thus, the South American bumblebee Bombus pauloensis is increasingly managed as an alternative species in this crop alongside honeybees. Herein, we evaluated the foraging patterns of the two species, concerning the potential pollen transfer between two blueberry co-blooming cultivars grown under open high tunnels during two seasons considering different colony densities.

Evaluating the Impact of Post-Emergence Weed Control in Honeybee Colonies Located in Different Agricultural Surroundings.

The honeybee is exposed to agricultural intensification, which leads to an improved reliance upon pesticide use and the reduction of floral diversity. In the present study, we assess the changes in the colony activity and the expression profile of genes involved in xenobiotic detoxification in larvae and adult honeybees from three apiaries located in agricultural environments that differ in their proportion of the crop/wild flora. We evaluated these variables before and after the administration of a mixture of three herbicides during the summer season.

Appetitive behavior of the honey bee in response to phenolic compounds naturally found in nectars.

The honey bee is the most frequently used species in pollination services for diverse crops. In onion crops (), however, bees avoid visiting certain varieties, being attracted differently to male sterile (MS) and fertile (OP) lines. These differences might be based on the phenolic profiles of the cultivars' nectars.

A successful approach to reducing bloodstream infections based on a disinfection device for intravenous needleless connector hubs.

When central line-associated bloodstream infections (CLABSIs) spiked in an oncology unit of an acute care hospital in Philadelphia from October 2009 to March 2010, noncompliance with intravenous needleless connector disinfection was suspected as a factor. The hospital implemented a disinfection cap, a device designed to address compliance/variance issues with connector disinfection protocols. However, the incidence of CLABSIs increased again in 1 unit, apparently as the result of poor compliance with cap use.

Genistein effects on quality of life and depression symptoms in osteopenic postmenopausal women: a 2-year randomized, double-blind, controlled study.

Summary: Postmenopausal estrogen decline is implicated in several age-related physical and psychological changes in women, including decreases in perceived quality of life. The phytoestrogen genistein at a dose of 54 mg daily in osteopenic postmenopausal women after 2 years implies an improvement on quality of life and depression symptoms.

Introduction: Postmenopausal estrogen decline is implicated in several age-related physical and psychological changes in women, including decreases in perceived quality of life (QoL).
