Sweet’s syndrome is a serious dermatologic disorder presenting with an abrupt onset of tender plaques or lumps, fever, joint pain, headache, oral and genital lesions. According to the clinical features and underlying causes, Sweet’s syndrome can be classified into classical (or idiopathic) Sweet\'s syndrome, Malignancy allied Sweet\'s syndrome, and Drug-induced Sweet\'s syndrome. It is multifactorial in etiology and the exact cause is still undetermined. The diagnosis can be confirmed by the routine histopathologic evaluation of lesional skin biopsy. Topical and systemic steroids are the first line treatment options. Hereby, we present a concise review of the pathogenesis, classification, and the management options of this rare disorder.
Disturbance-related drivers play a vital role in determining the spatio-temporal dynamics of riparian stand communities. This study evaluated stand structure responses to disturbance-related drivers, in Amobia, Ninian, Onwame and Pame riparian communities, in Kumawu District, Ashanti Region, Ghana. Trees were randomly sampled in 120 plots of 10 x 10 m2 dimension. Plots were laid perpendicular on the disturbance-related gradients. Individuals were quantified for their important value index, while ground cover was estimated using the Daubenmire cover abundance scale. Geometric series, Chao-1 and jackknife estimators and Hill numbers were performed to quantify community assemblages, while CCA was applied to evaluate the relationship between species assemblages and the distribution of associated environmental drivers. A total of 738 individuals, belonging to 24 families and 63 species, were recorded. Stand structural parameters were inversely related to stand composition and differed in their distribution. Amobia was the richest and diverse riparian community, in spite of registering the least stand structural parameters, while Ninian with the highest basal area, relative density, relative frequency and IVI, was the least rich and diverse; with majority of the stands being naturalized aliens and stress-tolerant (e.g., Senna alata and Tectona grandis). CCA results revealed that bushfire, grazing, farming and erosion explained 43.9% variability in stand community structure. The findings provide fundamental information on the stand structural dynamics and IVI in the four riparian communities, with a note that continuous disturbance especially in Ninian and Pame, may lead to future extinction of sensitive indigenous species, leaving only stress-tolerant invasive species
The paper examines the influence of corporate governance (CG) on the earnings quality (EQ) of listed companies in Vietnam. We consider the issue of CG integrated from each component of the board and the supervisory board. The study uses GLS regression method, data collected at energy enterprises listed on the stock market in Vietnam in the period of 2010 - 2018, with 2162 observations. The research results have found that the board has a positive impact on the EQ, while the supervisory board does not affect the earnings quality. Besides, the audit quality, the ratio of liabilities have a positive effect on the EQ, in contrast to the percentage of state ownership, the size of the company has an opposite effect on the EQ. In addition, foreign ownership ratio, profitability do not affect the EQ. The empirical research results are a useful basis to help companies improve the EQ, thereby helping companies to consider the elements of the board and supervisory more effectively for each companies.
In view of the current scenario, research using biodegradable polymers such as proteins and polysaccharides has been developed to minimize the disposal of synthetic plastic packaging in the environment, causing economic, social and ecological losses. The objective of this research was to evaluate the biodegradation behavior of films composed of lyophilized myofibrillary proteins (PML) from fish, palmitic fatty acid, cassava starch (AM) and glycerol in the soil. Initially, PML electrophoresis (SDS-PAGE) was performed to assess the purity of the samples after extraction. The biodegradation of composite films (F1- commercial film - PVC polyvinyl chloride), F2 (1% PML and 0.5% palmitic acid) and F3 (1% PML, 2% starch and 30% glycerol), was examined in conditions of burial of internal soil for 21 days, using the soil\'s natural microflora as a degradation medium, followed by the loss of percentage mass and by absorption spectroscopy in the infrared with attenuated total reflectance (FTIR/ATR). The electrophoretic profile of PML identified the presence of myosin and actin that are important for the production of films. Films F2 and F3 are considered biodegradable due to the high percentage of mass loss (%) and changes and displacement of amides in the FTIR, being confirmed by the molecular evaluation of the components of the structures of the films. As expected, PVC (F1) commercial synthetic film did not degrade. Thus, the two films evaluated (F2 and F3) are considered highly biodegradable in the soil, contributing to the reduction of environmental impact.
