The California lettuce and leafy greens industry has adopted the Leafy Greens Marketing Agreement (LGMA), which allows for 126 most-probable-number (MPN) Escherichia coli per 100 ml in irrigation water. Repeat irrigation of baby spinach plants with water containing E. coli O157:H7 and different levels of total organic carbon (TOC) was used to determine the epiphytic survival of E. coli O157:H7....

The U.S. FDA [1] process validation guidance document released in 2011 increased the emphasis on continued process verification: “ongoing assurance is gained during routine production that the process remains in a state of control”. Until recently, in a washing system, conductivity analysis was the only on-line method used to monitor the quality of the final rinse water. Now, developments in th...

We examined the use of dC, TOC and C/N geochemistry of sedimentary organic matter to reconstruct former sea levels and paleoenvironments in the absence of suitable microfossil data. The modern distribution of dC, TOC and C/N of 33 vegetation and 74 surface sediment samples collected from four coastal wetlands in the Thames Estuary and Norfolk, UK are described. The dC, TOC and C/N geochemistry ...

the removal of organic precursors of disinfection by-products (dbps), i.e. natural organic matter (nom), prior to disinfection is considered as the most effective approach to minimise the formation of dbps. trihalomethanes (thms) as the main group of dbps are categorized and considered to have the potentiality of increasing the rate of liver, kidney and cns adverse effects. this study which pre...

Intelligent personal assistants (IPA), such as Amazon Alexa and Google Assistant, are becoming increasingly present in multi-user households leading to questions about privacy consent, particularly for those who do not directly own the device they interact with. When these devices placed shared spaces, every visitor cohabitant becomes an indirect user, potentially discomfort, misuse of services...

We have previously reported that gamma-tocopherol (gamma-Toc) displays a natriuretic potency in rats fed a NaCl diet and administered 20 mg gamma-Toc. In this study, we investigated whether gamma-Toc has natriuretic potency at a dose lower or higher than 20 mg in rats given a NaCl diet. Male rats were fed a control diet or a NaCl diet and administered either placebo or 10, 20 or 40 mg of gamma-...

BACKGROUND For Chlamydia trachomatis (CT), a test of cure (TOC) within 3-5 weeks is not recommended. International guidelines differ in advising a Neisseria gonorrhoeae (NG) TOC. Retesting CT and NG positives within 3-12 months is recommended in international guidelines. We assessed TOC and retesting practices including extragenital testing in general practitioner (GP) practices located in diff...

The toucan (toc) gene is required in the germline for somatic cell patterning during Drosophila oogenesis. To better understand the function of toc, we performed a detailed analysis of the distribution of the Toucan protein during oogenesis. Toc expression is restricted to the germline cells and shows a dynamic distribution pattern throughout follicle development. Mislocalization of the Toc pro...

Transitions of care (TOC) refer to the movement of patients across institutions, among providers, between different levels of care, and to and from home. Medication errors that occur during TOC have the potential to result in medical complications that are serious for the patient and costly to the health care system. Positive outcomes have been demonstrated when pharmacists are involved in prov...
