The decades-long disposal of manufacturing waste containing perfluoroalkyl substances (PFAS) in landfills resulted in contamination of groundwater serving as the drinking water supply for the eastern Twin Cities metropolitan region. While measures were taken to reduce the levels of PFAS in the drinking water, questions remained about possible non-drinking water pathways of exposure in these communities. The Minnesota Department of Health (MDH) investigated whether PFAS in water used for yard and garden irrigation results in elevated concentrations of PFAS in soil and home-grown produce...

NPWT with instillation and dwell time (NPWTi-d), which combines NPWT with wound irrigation, has been clinically applied as a more effective treatment than conventional NPWT. Commercially available recombinant human basic fibroblast growth factor (rh-bFGF) has been demonstrated to be beneficial for use over the wound beds. The objective of this study was to evaluate the effectiveness of combined treatment with NPWTi-d and rh-bFGF. Six pigs received 12 full-thickness excisional skin wounds and were treated with 6 different treatment groups for each pair...

River regulation impacts riparian ecosystems by altering the hydrogeomorphic conditions that support streamside vegetation. Obligate riparian plants are often negatively impacted since they are ecological specialists with particular instream flow requirements. Conversely, facultative riparian plants are generalists and may be less vulnerable to river regulation, and could benefit from augmented flows that reduce drought stress during hot and dry periods. To consider this 'irrigation effect' we studied the facultative shrub, netleaf hackberry (Celtis reticulata), the predominant riparian plant along the Hells Canyon corridor of the Snake River, Idaho, USA, where dams produce hydropeaking, diurnal flow variation...

Bioaccumulation of several cyanotoxins has been observed in numerous food webs. More recently, the neurotoxic, non-proteinogenic amino acid β-N-methylamino-L-alanine (BMAA) was shown to biomagnify in marine food webs. It was thus necessary to assess whether a human exposure risk via a terrestrial food source could exist. As shown for other cyanotoxins, spray irrigation of crop plants with cyanobacterial bloom-contaminated surface water poses the risk of toxin transfer into edible plant parts. Therefore, in the present study, we evaluated a possible transfer of BMAA via spray irrigation into the seeds of one of the world's most widely cultivated crop plants, Triticum aestivum...

The ability to recover to original states after disturbances makes macroinvertebrates useful tools for assessing the impacts of pesticides. Many studies showed that direct exposure to pesticides decreases macroinvertebrate richness and alters their composition. The main objective of this study was to assess recovery patterns in macroinvertebrate communities after pesticide application in irrigated rice fields. We analyzed short-term temporal dynamics of macroinvertebrate communities after application of the herbicides bispyribac-sodium and clomazone and the insecticide chlorantraniliprole, over the rice-growing season in southern Brazil...

The Food and Drug Administration (FDA or we) is classifying the irrigating wound retractor device into class II (special controls). The special controls that apply to the device type are identified in this order and will be part of the codified language for the irrigating wound retractor device's classification. We are taking this action because we have determined that classifying the device into class II (special controls) will provide a reasonable assurance of safety and effectiveness of the device. We believe this action will also enhance patients' access to beneficial innovative devices, in part by reducing regulatory burdens...

Heatwaves are likely to increase in frequency and intensity with climate change, which may impair tree function and forest C uptake. However, we have little information regarding the impact of extreme heatwaves on the physiological performance of large trees in the field. Here, we grew Eucalyptus parramattensis trees for one year with experimental warming (+3 °C) in a field setting, until they were greater than 6-m-tall. We withheld irrigation for one month to dry the surface soils and then implemented an extreme heatwave treatment of four consecutive days with air temperatures exceeding 43 °C, while monitoring whole-canopy exchange of CO2 and H2 O, leaf temperatures, leaf thermal tolerance, and leaf and branch hydraulic status...

Abortion of fertilised ovaries at the tip of the ear can generate significant yield losses in maize crops. To investigate the mechanisms involved in this process, two maize hybrids were grown in field crops at two sowing densities and under three irrigation regimes (well-watered control, drought before pollination and drought during pollination), in all possible combinations. Samples of ear tips were taken 2-6 days after synchronous hand pollination and used for the analysis of gene expression and sugars. Glucose and fructose levels increased in kernels with high abortion risk...
