This article is a "call to action" in the service delivery of thickened liquids. We discuss the importance of staff education and further development of educational resources in dysphagia management involving the use of thickened liquids, particularly as related to inadequacies in staff education and training. We discuss the use of contemporary instructional strategies to promote accuracy in preparation and knowledge about the thickening process.Italy was the first western country to be hit by the initial wave of severe adult respiratory syndrome coronavirus 2 pandemic, which has been more widespread in the country's northern regions. Early reports showing that cancer patients are more susceptible to the infection posed a particular challenge that has guided our Breast Unit at Hub Hospital in Trento to making a number of stepwise operational changes. New internal guidelines and treatment selection criteria were drawn up by a virtual multidisciplinary tumour board that took into account the risks and benefits of treatment, and distinguished the patients requiring immediate treatment from those whose treatment could be delayed. A second wave of the pandemic is expected in the autumn as gatherings in closed places increase. We will take advantage of the gained experience and organisational changes implemented during the first wave in order to improve further, and continue to offer breast cancer management and treatment to our vulnerable patient population.Botanical gardens make unique contributions to climate change research, conservation, and public engagement. They host unique resources, including diverse collections of plant species growing in natural conditions, historical records, and expert staff, and attract large numbers of visitors and volunteers. Networks of botanical gardens spanning biomes and continents can expand the value of these resources. Over the past decade, research at botanical gardens has advanced our understanding of climate change impacts on plant phenology, physiology, anatomy, and conservation. For example, researchers have utilized botanical garden networks to assess anatomical and functional traits associated with phenological responses to climate change. New methods have enhanced the pace and impact of this research, including phylogenetic and comparative methods, and online databases of herbarium specimens and photographs that allow studies to expand geographically, temporally, and taxonomically in scope. Botanical gardens have grown their community and citizen science programs, informing the public about climate change and monitoring plants more intensively than is possible with garden staff alone. Despite these advances, botanical gardens are still underutilized in climate change research. To address this, we review recent progress and describe promising future directions for research and public engagement at botanical gardens.Chrysotile, which is classified as a class I carcinogen by the International Agency for Research on Cancer (IARC), has extensive application in the industry and can lead to lung or other cancers. However, whether chrysotile causes malignant mesothelioma and its molecular mechanism remain debatable. Thus, this study aimed to demonstrate the mesothelioma-inducing potential of chrysotile at the mesothelial cellular level and the function of microRNA-28 in malignantly transformed mesothelial MeT-5A cells. MeT-5A cells malignantly transformed by a nontoxic dose of chrysotile were named Asb-T, and miR-28 expression was downregulated in Asb-T cells. Restoration of miR-28 expression inhibited the proliferation, migration and invasion of Asb-T cells. We verified that IMPDH is a putative target of miR-28. The expression of IMPDH was significantly higher in Asb-T MeT-5A cells than in control cells, whereas the opposite trend was observed with miR-28 overexpression. Additionally, inhibition of IMPDH had similar effects as miR-28 overexpression. After miR-28 was elevated or IMPDH was inhibited, Ras activation was reduced, and its downstream pathways (the Erk and Akt signalling pathways) were inhibited. Surprisingly, the content of miR-28 in the blood of mesothelioma patients was higher than that in control subjects.  https://www.selleckchem.com/products/msa-2.html  Overall, nontoxic doses of chrysotile can cause malignant transformation of MeT-5A cells. Moreover, miR-28 inhibits the proliferation, migration and invasion of Asb-T MeT-5A cells, negatively regulates the expression of IMPDH through the Ras signalling pathway and may be an important therapeutic target.
  To evaluate the impact of preemptive metformin on the level of glycosylated hemoglobin (HbA1c) at 36weeks of pregnancy in women with gestational diabetes mellitus controlled by diet change (GDMA1).
 
  A randomized, double-blind, placebo-controlled trial was performed in a university hospital. Women with GDMA1 were recruited at 16-30weeks of pregnancy and randomized to oral metformin 500mg twice daily or identical placebo tablets to delivery. Level of HbA1c was taken at recruitment and at 36weeks of pregnancy. The primary outcome was the change in level of HbA1c at recruitment and 36weeks of pregnancy.
 
  Data from 106 participants were analyzed. The level of HbA1c during pregnancy increased significantly with a mean increase of 0.20%±0.31% (P<0.001; metformin) versus 0.27%±0.31% (P<0.001; placebo). An increment of 0.07% across trial arms was not significant (P=0.310). Mean birth weight was significantly lower in the metformin group (2.81±0.41kg vs 2.98±0.37kg; P=0.030). Rates of macrosomia (≥3.5kg; 0/53 [0%] vs 4/53 [8%]; P=0.123) and low birth weight (<2.5kg; 11/53 [21%] vs 5/53 [9%]; P=0.102) were not significantly different.
 
  Preemptive metformin did not prevent the level of HbA1c at 36weeks of pregnancy from rising nor significantly reduce the increase of HbA1c. Mean birth weight was significantly lower in the metformin arm with a non-significant trend to low birth weight, which is concerning.
 
  ISRCTN10845466.
 ISRCTN10845466.CE has been demonstrated to be a useful and powerful separation method for the characterization of charged and neutral molecules. Since the end of the 1980s and the development of the first commercialized CE device, the use of this separation method has continued to grow for academic and industrial research involving inexorably increasing of the number of CE users. Whatever the application domain, each CE user is daily confronted to the same problems often based on basic calculations of separation properties. In order to help the community of CE users to get quickly and easily a lot of information, and desiring to provide a tool running on mobile platforms, CEToolbox has been developed as a free Android application. Within few clicks, CEToolbox offers extensive injection information as injected volume, total capillary volume, proportion and amount of injected sample, rinsing time, and electrical field. Moreover, three additional tabs allow to obtain the calculation of the viscosity and the conductivity of BGE, and the separation flow rates.
