Abstract Children with cancer are frequently confronted with painful procedures during their course of care. To support them during their treatment, communication techniques derived from hypnosis have shown excellent results in reducing the distress and pain associated with these procedures. We conducted a preliminary study evaluating the effects of hypnotic communication training on nurses’ practice during painful procedures with children with cancer. The results showed good acquisition of the techniques by the nurses and the significant effects of these techniques on the children’s pain and distress levels. This study also provided recommendations for improving the training to develop a simpler design… More >

Abstract Objective: To evaluate the implementation of a daily practice using cardiac coherence in patients with peritoneal carcinosis who underwent surgery.
Materials and methods: Open, single-centre, controlled, randomized, and non-comparative phase II study, including 20 control patients versus 40 patients trained with biofeedback to use a breathing guide that will record their autonomous practice at home.
Expected results: Successful adhesion of this nonpharmacological intervention before and after surgery, which may characterize parameters in favor of its implementation and evaluation of its impact on anxiety.
Perspectives: Efficacy should then be assessed to transfer this supportive care to other patients.

Abstract Iron is an essential element for plants as well as all living organisms, functioning in various physiological and biochemical processes such as photosynthesis, respiration, DNA synthesis, and N₂ fixation. In the soil, Fe bioavailability is extremely low, especially under aerobic conditions and at high pH ranges. In contrast, plants with nodules on their roots that fix atmospheric nitrogen need much more iron. To highlight the physiological traits underlying the tolerance of N₂-fixing common bean to iron deficiency, two genotypes were hydroponically cultivated in a greenhouse: Coco nain (CN) and Coco blanc (CB). Plants were inoculated with an efficient strain of… More >

Abstract Biotechnological techniques provide a viable alternative to help improve and increase the production of plant species of agricultural and economic importance, which have been affected over the years by climate change, increasing their susceptibility to pests and/or diseases, generating losses in production as well as a decrease in their regenerative and genetic diversity. The application of biotechnological techniques such as in vitro mutagenesis offers a viable option for the generation of crops that are resistant to the different factors caused by abiotic and biotic stress. In vitro mutagenesis has been used in an efficient way to generate genetic changes in… More >

Abstract

One of the main reasons of the annual reduction in plant production all around the world is the occurrence of abiotic stresses as a result of an unpredicted changes in environmental conditions. Abiotic stresses basically trigger numerous pathways related to oxygen free radicals’ generation resulting in a higher rate of reactive oxygen species (ROS) production. Accordingly, higher rate of oxygen free radicals than its steady state causes to oxidize various types of molecules and compartments within the plants’ cells and tissues. Oxidative stress is the result of high amount free radicals of oxygen interfering with different functions leading to undergo… More >

Abstract Small ubiquitin-like modifier (SUMO) E3 ligases that facilitate the conjugation of SUMO proteins to target substrates contain an SP-RING domain which is like the RING domain found in ubiquitin E3 ligases. In this study, we isolated and characterized the Oryza sativa protein inhibitor of activated STAT like1 (OsPIAL1) containing SP-RING domains, as the rice homolog of Arabidopsis PIALs. OsPIAL1 interacts with OsSUMO proteins but does not interact with rice SUMO-conjugating enzymes (OsSCEs). An analysis of transgenic rice plant shows that OsPIAL1 is involved in SUMO conjugation to SCEs but not in SUMO conjugation to substrates. In addition, this OsPIAL1 activity… More >

Abstract Introduction: Studies on worry and distress in parents of a childhood cancer survivor are less developed in the literature. The aim of the study was to examine the intensity of worry and its association with intolerance of uncertainty factor and anxiety–depressive symptoms.
Methods: In total, 61 parents of a childhood cancer survivor (4–6 years of remission) participated in the study. Parents completed several questionnaires assessing worry, intolerance of uncertainty, and anxiety–depressive symptoms.
Results: The majority of parents suffer from anxiety symptoms and intense worries about the health of their childhood cancer survivor. The factor of intolerance of uncertainty seems to… More >

Abstract Background: The plant-growth-promoting rhizobacterium Tsukamurella tyrosinosolvens is a rare strain of actinomycete, in order to recognize and expand the ecological functions of rare actinomycetes. Methods: In this experiment, we studied the effect of Tsukamurella tyrosinosolvens P9 on the drought resistance of peanut by inoculating peanut seedlings in pots and measuring the growth and physiological indicators of peanut under drought stress and re-watering conditions. Results: The results showed that during drought stress, the relative water content of the soil and leaves, chlorophyll content, and stomatal length, width, and aperture were significantly decreased while the levels of malondialdehyde (MDA), H₂O₂ and stomatal… More >

Abstract Background: Nano-selenium has been widely used in antiviral and anticancer therapy, and has the advantages of good targeting and low toxicity. For the first time, we combined male reproduction with nano-selenium to investigate its antioxidant effect. This study investigated the protective effect of lentinan functionalized selenium nanoparticles on oxidative stress injury of the hydrogen peroxide (H₂O₂)-induced Leydig cell line, TM3. Methods: The suitable concentration of nano-selenium treatment to promote cell proliferation was also discussed. The concentration of 4 μM could significantly promote the growth of TM3 cells. Oxidative stress damage was caused using an 800 μM concentration of hydrogen peroxide.… More >
