Psoriasis is a common, chronic, immune mediated inflammatory disease that involves the innate immunological system (keratinocyte, dendritic cell, histiocytes, mast cells and endothelial cells) and acquired immunological system (T lymphocytes). Essential trace elements like iron (Fe), copper (Cu) undergo redox cycling and have physiological significance in inflammatory process. This study is aimed at measuring the level of copper, ceruloplasmin, iron and transferrin in psoriasis patient and to assess its relationship with the severity of the disease. This is an observational cross sectional study. It was conducted at the department of Dermatology and Venereology, BSMMU, Dhaka. Age range of the patient was 18 to 65 years. The mean age of the patients was 39.1±13.54 years, 57.9% patients were male and 42.1% were female. Male: female ratio was 1.4:1. Male patients were predominant. Mean duration of disease 5.36±4.05 years with range from 1.0 to 14 years. Most of the (76.3%) patients had mild disease followed by 23.7% had moderate to severe disease. Serum level of trace elements was compared between mild and moderate to severe group of psoriasis patients but difference were not statistically significant (p>0.05). Weak negative correlation was found between PASI score and serum levels of copper (r = “0.134, P = 0.423), iron (r = –0.080, p = 0.632), transferrin (r = –0.079, p = 0.638) and weak positive correlation was found with ceruloplasmin (r = 0.228, p = 0.168). The results of the present research provide valuable information and correlation between the measured biomarkers and severity of psoriasis. Serum Ceruloplasmin, copper, iron and serum transferrin could serve as a biomarker of psoriasis but not as a marker of psoriasis severity.

This article examines the effects of marital status to the gender gap in employment hours. This article uses linear regression analysis with data from the European Social Survey Round 8. Stata/SE 16 is used to analyze the data collected from 18 European countries to explore the research questions. Previous literatures identify some determinants of work hours such as demographic characteristics, the division of household labor, job characteristics, and country-level determinants (e.g., welfare state, work-hour regulations, family policies, part-time labor force participation etc.), but there are few studies on marital status as determinant of work hours. This article finds that there is an interaction among marital status and work hours to the different levels of gender. This article shows that there is a gender inequality in the European labor market, where men’s work hours are more than women’s work hours. Unmarried women work less hours than any other studied categories of marital status (e.g., married, divorced).
The aim of this study is explore the effect of foreign direct investment on agriculture and rural development. For this, panel data of 46 countries from Asia were accumulated for the time frame 1991–2018. The models OLS, POLS, 2SLS, and GMM are employed in this study. The study reveals that there is a favorable association between foreign direct investment and agricultural land as percentage of total land using the models OLS, POLS, 2SLS. In stark contrast, value added for agriculture, forestry, and fishing has an unfavorable association with foreign direct investment in all models employed in the study. Furthermore, female employment in agriculture has a negative association with foreign direct investment in OLS, 2SLS and GMM models, whereas male employment in agriculture has a negative association with foreign direct investment in the POLS model only. Land under cereal production has a favorable association with foreign direct investment in all models except POLS, and permanent cropland has a favorable association with foreign direct investment in all models except GMM. In addition, rural population has a positive relationship with foreign direct investment in OLS, POLS and 2SLS and a negative relationship with foreign direct investment in GMM.
