The purpose of this study was to characterize the potential of vitamins to protect the retinal pig-ment epithelium (RPE) from oxidative stress (OS). We have previously shown that OS induces the expression of AP1 transcription factors (FOSB, CFOS and ATF3), but is modulated by pretreatment with vitamin C (200 μm). We propose that OS-induced AP1 expression can be used as a biomarker of OS to test the efficacy of vitamins to limit the impact of OS in the RPE. Here we examined the efficacy of vitamin E or combined vitamin A plus vitamin C to modulate OS-induced AP1 expression in the RPE. We pretreated human ARPE-19 cells with vitamin E (0 - 7.5 μm) or with combined vitamin A (10 or 15 μm) plus vitamin C (50 or 100 μm) for 3 days prior to exposure to 500 μm H2O2 OS for 1 - 4 h. AP1 expression was assessed using qRT-PCR. Pretreatment with ≥2.5 μm vitamin E significantly decreased OS-induced AP1 expression at 1 - 4 h OS, compared to controls. Lower doses of vitamin E were ineffective at modulating OS responses. Pretreatment with 100 μm vitamin C combined with 15 μm vitamin A protected RPE cells from OS-induced AP1 expression. There is an additive and potentially protective effect of 100 μm vitamin C and 15 μm vitamin A on FOSB expression at 4 h, and a potentially protective effect of 100 μm vitamin C and 15 μm vitamin A on CFOS expression at 1 h OS. A protective effect was also seen with 15 μm vitamin A pretreatment alone on ATF3 expression. Thus, “sub-therapeutic” levels of multiple vitamins may protect RPE cells better than higher doses of a single vitamin. This OS-induced AP1 expression biomarker assay may be useful to identify complex antioxidant formulations as therapeutics for degenerative diseases that are thought to be caused by OS, like age-related macular degeneration.

The objective of this study was to evaluate the growth, the nutrition, and the intensity of the green color in corn plants in monoculture and in intercropping with mucuna aterrima, Crotalaria juncea, and Canavalia ensiformis, cultivated with different handlings. In general, corn plants in monoculture demonstrated greater growth and greater SPAD value in the first evaluation, despite presenting lower tenor of phosphorus in the leaves when related to the corn in intercropping. The weed helps in the growth of the corn plant and increases the SPAD value during flowering. The monoculture NPK (Nitrogen, Phosphorus and Potassium) fertilization promoted higher values in corn plant growth, as well as a greater SPAD value, at 30 d.a.e., of the plants. The NPK-fertilized corn plants showed a greater tenor of sulphur and a lower tenor of molybdenum. The corn in intercropping with m. aterrima resulted in smaller plants at 70 d.a.e. It also presented a greater tenor of molybdenum and lower tenor of nickel when compared to intercroppings with C. juncea and with C. ensiformis. The corn plants in a intercropping with Crotalaria juncea presented higher growth at 30 and 70 d.a.e. and greater tenors of molybdenum when compared to the plants in intercropping with C. ensiformis.

Objective: To characterize the scientific production related to the impact of urinary incontinence on quality of life of pregnant women. method: An integrative review carried out from September 2014 to may 2015. The search was conducted in six databases, and a final sample of seventeen publications was presented. The data were presented in tables. Results: Incontinence related factors are: Being older, second pregnancy, multiparity, constipation, smoking, and obesity. Stress incontinence is the most occurring in pregnant women, causing an adverse impact on quality of life. Discussion: It is for health professionals who try to create effective coping strategies for minimizing consequences generated by the accidental loss of urine. Conclusion: Urinary incontinence affects the mother’s life, resulting in social, behavioral, physical and emotional harm, taking this woman to be excluded from society and feel insecure about their health.

Agriculture is essential for providing food and maintaining food security while concurrently delivering multiple other ecosystem services. However,agricultural systems are generally a net source of greenhouse gases and ammonia. They, therefore, need to substantively contribute to climate change mitigation and net zero ambitions. It is widely acknowledged that there is a need to further reduce and mitigate emissions across sectors, including agriculture to address the climate emergency and emissions gap. This discussion paper outlines a collation of opinions from a range of experts within agricultural research and advisory roles following a greenhouse gas and ammonia emission mitigation workshop held in the UK in march 2022. The meeting identified the top mitigation priorities within the UK's agricultural sector to achieve reductions in greenhouse gases and ammonia that are compatible with policy targets. In addition, experts provided an overview of what they believe are the key knowledge gaps, future opportunities and cobenefits to mitigation practices as well as indicating the potential barriers to uptake for mitigation scenarios discussed.
