Fecal contamination of water sources is an important water quality issue for agricultural irrigation ponds. Escherichia coli concentrations are commonly used to evaluate recreational and irrigation water quality. We hypothesized that there may exist temporally stable spatial patterns of E. coli concentrations across ponds meaning that some areas mostly have higher and other have mostly lower than average concentrations of E. coli To test this hypothesis, we sampled two irrigation ponds in Maryland in nodes of spatial grids biweekly during the summer of 2016...

BACKGROUND: The use of a ureteral stent can cause a urinary tract infection (UTI), although it reduces urologic complications. UTIs are associated with a higher rate of ureteral stent colonization (USC). The aim of this study was to compare USC in living and deceased donor renal transplant recipients. MATERIAL AND METHODS: We conducted a prospective study of 48 patients who underwent renal transplantation between January and December 2016. The stents were removed aseptically, the inner surface of proximal and distal ends of stents were irrigated with liquid culture medium, and then they were vortexed for bacteriological investigation...

Soil cadmium (Cd) contamination and drought stress are among the main issues hindering global food security. Biochar has been used to reduce metal uptake by plants and water stress mitigation, but long-term residual effects of biochar under Cd stress at different moisture levels needs to be investigated. A following rice (Oryza sativa L.) was grown after wheat on Cd-contaminated soil amended with different levels of biochar (0, 3.0, and 5.0%, w/w). Thirty five days old plants were irrigated with three moisture levels including zero drought as a control (1-2 cm water layer on soil), mild drought (MD, 50% of soil water holding capacity, WHC), and severe drought (SD, 35% of soil WHC) for an accompanying 35 days...

BACKGROUND: Lumbar radicular pain often results from lumbar disc herniation, spinal stenosis, or degenerative spondylolisthesis. Minimally invasive disc decompression procedures, such as nucleo-annuloplasty or epiduroscopic neural decompression by laser, have been devised to treat such pain. OBJECTIVE: The short-term outcomes of disc decompression by endoscopic epidural laser decompression (EELD) or transforaminal epiduroscopic laser annuloplasty (TELA) were compared in patients with lumbar radicular pain due to disc herniation...

Hydrogen peroxide has been used in medicine for more than 100 years. It is known in surgery as a highly useful irrigation solution by virtue of both its hemostatic and its antimicrobial effects. Due to its possible negative effect on wound healing and its cytotoxic effect in higher concentrations, there are concerns about the safety of its use. The objective of this paper is to review the safety and beneficial effects of hydrogen peroxide.

For the first time, the influence of different vine management was evaluated in relation to volatile profile and sensory perception through GC×GC/TOFMS, QDA, GC-FID, GC/MS, and GC-O. GC×GC/TOFMS analyses and QDA have shown that a larger spacing between vine rows (2 rather than 1m), attachment of shoots upwards, and irrigation did not result in wine improvement. Conversely, wines elaborated with grapes from a vine with a lower bud load (20 per plant; sample M1) stood out among the other procedures, rendering the most promising wine aroma...

The demand for global freshwater is growing, while global freshwater available for human use is limited within a certain time and space. Its security has significant impacts on both the socio-economic system and ecological system. Recently, studies have focused on the urban water security system (UWSS) in terms of either water quantity or water quality. In this study, water resources, water environment, and water disaster issues in the UWSS were combined to establish an evaluation index system with system dynamics (SD) and geographic information systems (GIS)...

Craniomaxillofacial injuries produce complex wound environments involving various tissue types and treatment strategies. In a clinical setting, care is taken to properly irrigate and stabilize the injury, while grafts are molded in an attempt to maintain physiological functionality and cosmesis. This often requires multiple surgeries and grafts leading to added discomfort, pain and financial burden. Many of these injuries can lead to disfigurement and resultant loss of system function including mastication, respiration, and articulation, and these can lead to acute and long-term psychological impact on the patient...

A 42-years-old male presented with left medial canthal swelling, accompanied with only mild epiphora. There was no history of dacryocystitis, mid-facial trauma, surgery, or bloody tears. On examination, there was an immobile, subcutaneous, non-inflammatory mass below the medial canthal tendon. Lacrimal irrigation showed blockade at the nasolacrimal duct. A computerized axial tomography (CAT) scan revealed a non-enhancing, low-density, cystic lesion at the inferomedial margin of the orbit. There were no signs of bony erosion, consistent with idiopathic acquired dacryocystocele...

Endophthalmitis is one of the most serious complications of cataract surgery. The surgeons try to reduce the incidence of endophthalmitis. In order to prevent postoperative infection, irrigation of the conjunctival sac with povidone iodine and injection of antibiotics into the anterior chamber before the end of the surgery are used. Although there are a lot of reports about the concentration, mode and duration of povidone iodine application, there is no consensus. There are many options for antibiotics, including cefuroxime, vancomycin and moxifloxacin...

Sewage treatment plants (STPs) are one of the sources of pathogens discharged into surface water. An investigation was carried out over the duration of 12 months in Henan Province, China, to evaluate the health influence of municipal wastewater effluent discharge on water quality of the receiving water. A discharge-based quantitative microbial risk assessment (QMRA) was employed, taking into account the vegetables consumption habits of the Chinese, population subgroups with different immune statuses and ages, to evaluate the incremental disease burden from agricultural irrigation and swimming exposure scenarios associated with increased concentration of the protozoan Cryptosporidium and/or Giardia in the receiving river...

Regulation of agriculture irrigation water discharges in California is assessed and controlled by its nine Regional Water Quality Control Boards under the jurisdiction of the California State Water Resources Control Board. Each Regional Water Board has developed programs to control pesticides in runoff as part of the waste discharge requirements implemented through each Region's Irrigated Lands Regulatory Program. This study assessed how pesticide use patterns differ in the Imperial (Imperial County), Salinas and Santa Maria (Monterey County) valleys, which host three of California's prime agriculture areas...

Filter drains are usually laid along the margins of highways. Highway runoffs are polluted with hydrocarbons and high levels of total dissolved solids. Therefore, effective pollution removal mechanism is necessary in order to avoid contamination of surrounding soils and groundwater. Biodegradation is amongst pollution removal mechanisms in filter drains, but it is a relatively slow process which is dependent on wide range of factors including the type of pollutant and availability of nutrients. This paper reports on a study conducted to investigate the impact of slow-release fertilizer and struvite in enhancement of biodegradation of hydrocarbon in filter drains...

Citrus hydraulic physiology and PIP transcript levels were characterized in heavy (clay) and light (sandy loam) soils with and without treated waste water (TWW) irrigation after a summer irrigation season and at the end of a winter rainy season recovery period. Consistent reductions in clay soils compared to sandy loam were found for fresh water (FW) and TWW irrigation, respectively, in root water uptake, as well as in hydraulic conductivity of whole plant (Ks plant), stem (Ks stem) and root (Ks root). Transcript levels of most PIPs down-regulated following TWW irrigation in both soils, but relative gene expression of three PIPs was significantly higher in summer for sandy soil and FW than for clay soil and TWW; their mRNA levels was significantly correlated to Ks root...
