Everything Matters: The ReproNim Perspective on Reproducible Neuroimaging

There has been a recent major upsurge in the concerns about reproducibility in many areas of science. Within the neuroimaging domain, one approach is to promote reproducibility is to target the re-executability of the publication. The information supporting such re-executability can enable the detailed examination of how an initial finding generalizes across changes in the processing approach, and sampled population, in a controlled scientific fashion. ReproNim: A Center for Reproducible Neuroimaging Computation is a recently funded initiative that seeks to facilitate the “last mile” implementations of core re-executability tools in order to reduce the accessibility barrier and increase adoption of standards and best practices at the neuroimaging research laboratory level. In this report, we summarize the overall approach and tools we have developed in this domain

The low-FODMAP diet as an effective tool for managing irritable bowel syndrome – an assessment of adult patients’ knowledge of dietary guidelines

Background. Irritable bowel syndrome (IBS) is the most common gastrointestinal disorder that is driven by the gut- brain axis and affects 1-20% of the population. Most patients note that various foods elicit abdominal symptoms, and they eliminate these products from their diets. A diet that is low in fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAP) is currently one of the mainstays in IBS treatment. Objective. The aim of this study was to assess the knowledge of IBS patients about the disease, treatment and the principles of the low-FODMAP diet that can alleviate gastrointestinal symptoms. Material and methods. The participants were adults diagnosed with IBS, the inclusion criteria were: absence of comorbidities requiring an elimination diet, age over 18 years, and consent to participate in the study. The respondents filled out an anonymous questionnaire containing questions about the IBS diagnosis, disease history and treatment, as well as 45 questions assessing the participants’ knowledge about the low-FODMAP diet. Results. In 28% of the cases, IBS was diagnosed by a general practitioner; in nearly 40% of the cases – by a gastroenterology specialist; in 10% of the cases – by a dietitian, whereas the remaining respondents had arrived at the diagnosis independently or with the help of support groups for IBS patients. After diagnosis, only every fourth respondent sought treatment in a gastroenterology clinic. In the studied population, 237 of the respondents had followed to the low-FODMAP diet, and the differentiating factors were sex (p=0.002), place of residence (city with apopulation higher than 100,000 vs. rural area; p=0.0001) and education (university vs. vocational school p=0.0043). Respondents who had been recently diagnosed with IBS (less than 12 months vs. more than 12 months before the study) were more likely to follow the FODMAP diet. Conclusions. The surveyed population was characterized by high levels of knowledge about the low-FODMAP diet, but many respondents did not strictly comply with dietary guidelines, in particular the duration of each dietary phase. Age was significantly correlated with the respondents’ knowledge, and the participants’ familiarity with low-FODMAP guidelines decreased with age. Nutritional consultations did not significantly improve the respondents’ knowledge about the low-FODMAP diet

The leaf spotting of Crassula multicava and potential methods of their chemical control

The aim of this work was to determine the cause of leaf spotting of Crassula multicava and potential methods of their control. The leaves of succulent Crassula multicava growing in greenhouse conditions showed disease symptoms, yellow and gradually browning spots, and the disease was caused by Pestalotiopsis guepinii . The strobilurin fungicides, azoxystrobin (Amistar 250 SC), kresoxim - methyl (Discus 500 WG) and chlorotalonil with addition of zinc (Gwarant 500 SC) greatly inhibited the growth of Pestalotiopsis guepinii . Total inhibition of the myce lium growth was observed when azoxystrobin at concentration of 6 μ g/cm³ was added. Kresoxim - methyl and chlorotalonil with addition of zinc at a concentration of 10 μ g/cm³ limited the mycelium growth in 98% and 80% respectively. The inhibitory effect was gr eater for azoxystrobin than kresoxim - methyl and chlorotalonil. Preventively and curatively used of synthetic analogs of strobilurins and Gwarant greatly limited the development of Pestalotiopsis guepinii
