Launch of the European Society for Dermatological Research (ESDR) in 1970 coincided with genetics also entering a new era. Arriving alongside new models of DNA structure and the discovery of restriction endonucleases, the ESDR has parallel-tracked 50 years of major developments in genomics, technological innovations, and big data. Patients with rare Mendelian genetic skin diseases have witnessed the discovery of causative genes and pathogenic variants, improved genetic counseling, and the advent of prenatal diagnosis. Translational research has also heralded early phase clinical trials of gene, cell, and protein therapies, as well as enhanced disease models, mechanism-based therapies, and impactful clinical progress.Metastasis is the main reason for the high mortality of patients and indeed a difficult task in the treatment of cutaneous melanoma. Therefore, it is of great clinical value to explore the molecular mechanism of cutaneous metastatic melanoma and develop novel therapies. MED1, acting as a factor required for activator-dependent transcription, is reported to be involved in carcinogenesis and progression. In this study, we found that MED1 was highly expressed in patients with cutaneous melanoma. MED1 downregulation could induce cellular epithelial-to-mesenchymal transition and promote migration, invasion, and metastasis of cutaneous melanoma in vivo and in vitro. Further analysis showed that in Med1 knockdown cells, the TGFβ/SMAD2 signaling pathway mediated an increase in epithelial-to-mesenchymal transition phenotype and migration. The opposite results were observed after treatment with TGFβ inhibitors. To further explore the mechanism, we found that MED1 interacted with SMAD2, and MED1 downregulation could protect SMAD2 from degradation by inhibiting SMAD2 ubiquitination. Together, these results suggest that MED1 inhibited TGFβ signaling pathway to reduce cell epithelial-to-mesenchymal transition phenotype and migration through SMAD2 ubiquitination in the metastasis of cutaneous melanoma. selleck Our findings elucidated the role of MED1 in the metastasis of cutaneous melanoma and provided a target for the therapeutic strategies of cutaneous melanoma.Patient-reported outcomes (PROs) provide quantitative assessments of patients' experiences with their skin diseases. link2 PROs are usually much more comprehensive than what can be gleaned from a brief clinical history and more informative than what dermatologists can gather on clinical examination. Correlations between PROs and clinician assessments (e.g., investigator global assessment, PASI) are poor to moderate at best, and therefore data from each source are not redundant and can complement one another. PROs should serve as skin vital signs in dermatology. PROs can offer snapshots of the intensity of a symptom as well as the effects of symptoms, emotions, and functioning on a patient's skin-related QOL. Just as clinicians obtain a baseline blood pressure before starting antihypertensives, dermatology-specific PROs serve as a baseline from which clinicians can monitor (even remotely) for improvement or side effects with treatment and for flares. Both PROs and conventional vital signs are usually normal. It is when they are abnormal or different than expected that they become informative. We conclude by offering a roadmap for investigators to conduct the next steps in PRO research necessary to establish guidelines for transitioning PROs from clinical research and trials to routine clinical use.Ruxolitinib is a Janus kinase 1/2 inhibitor that blocks signal transduction of interferon-gamma, a critical cytokine involved in the pathogenesis of cutaneous lichen planus (LP). In this prospective phase II study, we investigated the efficacy of topical ruxolitinib in cutaneous LP and performed transcriptomic analysis before and after therapy. Twelve patients with cutaneous LP applied topical ruxolitinib twice daily for 8 weeks. Primary endpoints were changes in total lesion count and changes in modified Composite Assessment of Index Lesion Severity score in index treated and untreated index control lesions at week 4. link3 Total lesion count decreased by a median of 50 lesions (interquartile range 25, 723; P less then 0.001). modified Composite Assessment of Index Lesion Severity scores decreased by a mean difference of 7.6 (standard deviation 8.8, P = 0.016) between index treated and control lesions. Type I and II interferon pathways were enriched in LP, and responsive disease displayed downregulation of interferon-stimulated genes. In this small pilot study, topical ruxolitinib was highly effective in the treatment of cutaneous LP. Transcriptomic analysis confirmed LP as an interferon-driven disease and downregulation of interferon-stimulated genes correlated with disease response.Algal culturing in photobioreactors for biofuel and other value-added products is a challenge globally specifically due to expensive closed or open photobioreactors associated with the high cost, problems of water loss and contamination. Among the wide varieties of microalgae, diatoms have come out as potential source for crude oil in the form of Diafuel™ (biofuel from diatoms). However, culturing diatoms at large scale hypothesized as diatom solar panels for biofuel production is still facing a need for facile and economical production of value-added products. The aim of this work was to culture diatom (microalgae) in a closed system by sealing the reactor rim tightly with very cheap priced and used plastic bubble wrap material which is generally discarded in a lodging and transportation of goods. To optimize it, different plastic wraps discarded from a plastic industry were tested first for their permeability to gases and impermeability to water loss. It was found that among different varieties of plastic bubble wraps, low density polyethylene (LDPE) bubble wrap material which was used to seal glass containers as photobioreactors allowed harvest of maximum Diafuel™ (37%), lipid (35 μgmL-1), highest cell count (1152 × 102 cells mL-1), maximum CO2 absorbance (0.084) with almost no water loss and nutrient uptake for 40 days of experiments. This was due to its permeability to gases and impermeability to water. To check usability of such LDPE bubble wrap on other microalgae it was therefore tested on the red-green microalgae Haematococcus pluvialis, which showed scope to be scaled up for astaxanthin production using discarded bubble wrap packing material. This study thus would open up a new way for decreasing plastic disposal and with reuse for sustainable development and application of diatom in biofuel production which could find applications in environmental and industrial sectors.Land use change (LUC) is identified as one of the main drivers of soil erosion in the Mediterranean. However, very little information exists regarding the relationship between land use and erosion over longer time periods and on regional scales. We quantified the LUC in Southern Spain between 1956 and 2018, examining its effect on soil erosion and assessing the mitigation role of the permanent grassland (PG). The land use influence on erosion is represented by the RUSLE's C-factor, which was modelled using the Monte Carlo Method (MCM) based on historical LUC. Moreover, future LUC scenarios by 2038 were developed by binary logistic model (scFS) and by a complete conversion of PG to cropland (scPC), permanent crop (scPP) and forest and natural (scFP). Historically, Southern Spain has experienced an impressive intensification of its agricultural system. While soil loss variation is noted within the classes, no big variation is observed in cumulative erosion on a regional scale. The underlying reasons for this resilience are multifold, but mainly attributed to the fact that a small fraction of the total surface (20%), dominates total erosion (67%). The C-factor decrease in this area displays a LUC towards forest and natural area, suggesting an agriculture abandonment. On the other hand, the agricultural intensification that has taken place in the remainder of the area, contributes much less to overall soil erosion. Future LUC scenarios illustrate the importance of PG for erosion mitigation. scFS scenario does not project major changes. However, scCP and scPP, show an abrupt increase in regional erosion by 13% and 14%, while scFP shows a negligible reduction of erosion close to 0%. This allows to quantify the erosion mitigation offered by maintaining the PG and should be taken into account for future agricultural policy.The Bajos Submeridionales (BBSS) (Argentina) is a 54,800 km2 hydrological system located at the distal part of the Salado-Juramento Fluvial Megafan (SJRM). Its climate evolves from humid-subtropical in the east to semiarid in the west. Its hydrogeological system is typical of extensive plains, topography locally imposes vertical flows and neotectonic elements define system boundaries and drains. These characteristics and poor data availability represent a major challenge for identifying a hierarchical subsurface flow system and the influence of neotectonics. This work characterizes the hydrogeology of the BBSS and proposes a conceptual model based on integrated systematic information including 453 water level, 145 hydrochemical, and 99 δ18O- δD data. Four hydrogeological units are identified (HU1-HU4), two of which are divided into sub-units based on their sedimentary sequence. The main chemical types are Na-Cl, Na-Cl/SO4, Na-HCO3/Cl, Na-Cl/HCO3, and HCO3-Na. Dominant ions are Na, Cl, and SO4.

The ever-changing regulations on the use of refrigerants have often posed great challenges to the refrigeration industry and there is a pressing need to develop new refrigerants and develop better equipment to use them. Theoretically, an ideal refrigerant should possess characteristics such as low-global warming potential (GWP), non-toxic, non-flammable, and zero-ozone depletion potential (ODP). In addition, the refrigerants are also expected to have excellent thermodynamic and thermophysical properties. Many new synthetic refrigerants have been reported as alternative refrigerants and have very low atmospheric life as well as low GWP and zero-ODP. However, it is irrefutable that most of the studies that reported the so-called new refrigerants are actually not new. From the invention of R-12 (Dichlorodifluoromethane) in 1930s to the invention of R-1234yf in 2000s, these substances are available for decades even before being recognized as refrigerants. This review attempts to provide chronicles on different aspects of refrigerants such as their progress since their invention in the early 1800s, classification and properties. In addition, concepts such as issues associated with the long-term use of refrigerants, barriers for the inclusion of low-GWP refrigerants, various protocols and accords that have occurred since the inception of refrigerants are also critically discussed.
