Community-Based Strategies to Improve Health-Related Outcomes in People Living With Hypertension in Low- and Middle-Income Countries: A Systematic Review and Meta-Analysis.

Background: Individuals living with hypertension are at an increased risk of cardiovascular- and cerebrovascular-related outcomes. Interventions implemented at the community level to improve hypertension control are considered useful to prevent cardiovascular and cerebrovascular events; however, systematic evaluation of such community level interventions among patients living in low- and middle-income countries (LMICs) is scarce.

Methods: Nine databases were searched for randomized controlled trials (RCTs) and cluster randomized control trials (cRCTs) implementing community level interventions in adults with hypertension in LMICs.

Short-lived positron emitters in beam-on PET imaging during proton therapy.

The only method for in vivo dose delivery verification in proton beam radiotherapy in clinical use today is positron emission tomography (PET) of the positron emitters produced in the patient during irradiation. PET imaging while the beam is on (so called beam-on PET) is an attractive option, providing the largest number of counts, the least biological washout and the fastest feedback. In this implementation, all nuclides, independent of their half-life, will contribute.

The determination of nitrogen dioxide in ambient air with free hanging filters as passive samplers, and a new calibration method using fritted bubblers.

This paper describes two new methods for the determination of NO(2) in the ambient air. The first method consists of free hanging filters with a diameter of 2.5 cm as passive samplers.

A transformation method for obtaining marker-free plants of a cross-pollinating and vegetatively propagated crop.

It is generally thought that transformation of plant cells using Agrobacterium tumefaciens occurs at a very low frequency. Therefore, selection marker genes are used to identify the rare plants that have taken up foreign DNA. Genes encoding antibiotic and herbicide resistance are widely used for this purpose in plant transformation.

The influence of geometry and draught shields on the performance of passive samplers.

Passive samplers provide an excellent opportunity to perform indicative measurements or establish a dense network of measuring sites. A drawback compared with conventional active measuring methods is the larger spread of results. This variation can, to a large extent, be attributed to the influence of temperature, sampler geometry and wind on sampling results.
