Economic actors and the problem of externalities : could financial markets play a role in democratic backsliding?

Purpose: Economic actors tend to exert powerful impact on socio-economic and political developments around the globe, including yielding financial and political crises in developed democracies. Approach/Methodology/Design: While a number of studies discuss the impact of finance on political and societal reality, research on the interlink between finance and democratic processes is very limited. Drawing on secondary literature and a case study of two young Central-European democracies, this paper contends a relationship between financial economy and democratic backsliding. Findings: The findings challenge the existing conventional accounts of the reversal to authoritarian politics in Poland and Hungary. Practical Implications: They also identify a mismatch between the constitutional foundations for embedding the market within the society and its institutions on the one hand, and the political-institutional reality in contemporary democracies. Originality/Value: The research provides theoretical assumptions encouraging further study on unwelcome externalities produced by financial markets.peer-reviewe

Evaluation of caspase 1 and sFas serum levels in patients with systemic sclerosis: correlation with lung dysfunction, joint and bone involvement.

Recent studies point out at the role of apoptosis disturbances in the development of systemic sclerosis (SSc)

Administration of testosterone inhibits initiation of seminal tubule growth and decreases Sertoli cell number in the earliest period of rat's postnatal development.

Sertoli cell (SC) number determines testes size and their capacity to produce spermatozoa. In the rat SC proliferate until 15th postnatal day (PND). Their proliferation is stimulated by FSH and inhibited by estradiol, but the role for androgens is uncertain. In this study we analyzed the effects of testosterone administration on testes growth and SC number in relation to timing of the treatment. Male rats were injected with 2.5 mg of testosterone propionate (TP) from birth until 5th PND and autopsied either on 6th PND [TP1-5(6)] or on 16th PND [TP1-5(16)] (transient administration). Other rats received TP from birth until 15th PND [TP1-15] or between 5th and 15th PND [TP5-15] continuously and were autopsied on day 16th. Control groups (C) received vehicle. In the Cs serum level of estradiol was 20-fold higher (

Clinical significance of circulating dendritic cells in patients with systemic lupus erythematosus.

Dendritic cells are a complex group of mainly bone-marrow-derived leukocytes that play a role in autoimmune diseases. The total number of circulating dendritic cells (tDC), and their plasmacytoid dendritic cell (pDC) and myeloid dendritic cell (mDC1 and mDC2) subpopulations were assessed using flow cytometry. The number of tDC and their subsets were significantly lower in systemic lupus erythematosus patients than in the control group. The count of tDC and their subsets correlated with the number of T cells. The number of tDC and pDC subpopulation were lower in the patients with lymphopenia and leukopenia than in the patients without these symptoms. Our data suggest that fluctuations in blood dendritic cell count in systemic lupus erythematosus patients are much more significant in pDC than in mDC, what may be caused by their migration to the sites of inflammation including skin lesions. Positive correlation between dendritic cell number and TCD4+, TCD8+ and CD19+ B cells, testify of their interactions and influence on SLE pathogenesis. The association between dendritic cell number and clinical features seems to be less clear

Pigment Protection Factor as a Predictor of Skin Photosensitivity – A Polish Study

Assessment of individual photosensitivity by determining the minimal erythema dose (MED) is commonly accepted. MED objectively describes a single individual response to the irradiation of skin with a particular wavelength (UVB, UVA). Pigment protection factor (PPF) is an objective value to measure skin type. The aim of the project was to analyze PPF values in the population of Lodz and the relationship between PPF, skin phototype, and individual MED. The study was conducted on the group of 270 volunteers: 130 men and 140 women, mean age 28.5 years (OS + 9.66) with either skin phototype II or III, as defined by Fitzpatrick Skin Phototype Classification. Phototesting of each volunteer was undertaken with an increasing dose series (UVB radiation) on six squares (1×1 cm) on the skin of the back. The MED was defined as a perceptible erythema 24 hours later. Starting dose was determined by history, physical examination, and phototype ranged from 0.03-0.07 J/cm2. PPF was measured by a skin reflectance meter UV Optimize 555. The mean MED value was 0.15 J/cm2 and the PPF value was 6.15. A positive correlation between the MED value and PPF (R=0.38; P&lt;0.001), and a positive correlation between phototype and MED and PPF (P&lt; 0.001) were found. Both determination of MED and PPF are objective methods of photosensitivity assessment, but PPF determination is an easy and non-invasive method.</p

During seminiferous tubule maturation testosterone and synergistic action of FSH with estradiol support germ cell survival while estradiol alone has pro-apoptotic effect.

During establishment of spermatogenesis at the prepubertal age, an early germ cells apoptotic wave occurs likely aimed to remove abnormal germ cells and to maintain a proper cell number ratio between maturating germ cells and Sertoli cells. Here we assessed Sertoli and germ cell apoptosis in relation to morphological parameters of Sertoli cell maturation in neonatal rats under the influence of testosterone, estradiol and FSH given alone or in combinations. From postnatal day (PND) 5th to 15th male rats were daily injected with: 1) 2.5 mg of testosterone propionate (TP), or 2) 12.5 microg of 17beta-estradiol benzoate (EB), or 3) TP+EB, or 4) 7.5 IU of human purified FSH (hFSH), or 5) hFSH+EB or solvents (control-C). Autopsy was performed on PND 16th. Sertoli cell nuclei area and incidence of seminiferous tubule lumen formation (LF) were taken as markers of Sertoli cell maturation. Sertoli and germ cell apoptosis was assessed using TUNEL method. In comparison with C, the area of Sertoli cell nuclei was significantly reduced after EB (25.7+/-2.0 vs. 30.9+/-1.6 microm2 for C,

Allergic diseases, drug adverse reactions and total immunoglobulin E levels in lupus erythematosus patients.

BACKGROUND: The association of allergic diseases, drug adverse reactions and elevated total immunoglobulin E (IgE) concentration in systemic lupus erythematosus patients remains controversial. The aim of the study was to investigate the prevalence of those features in active and inactive systemic lupus erythematosus patients, and in the control group as well. METHODS: Total IgE concentration was evaluated by enzyme-linked immunosorbent assay. RESULTS AND CONCLUSIONS: The results of our study revealed that concomitant allergic diseases were not more frequent in systemic lupus erythematosus patients than in the general population. Total IgE concentration was significantly higher during the active stage of the disease. Drug reactions were very frequent but not connected with IgE elevation. Our results indicate that IgE may play a role in lupus pathogenesis, especially in the active phase of the disease

The number and distribution of blood dendritic cells in the epidermis and dermis of healthy human subjects.

Human blood dendritic cells (BDC) can be divided into three subsets: plasmacytoid DC (PDC) and two myeloid subsets--MDC1 and MDC2. Several studies revealed the presence of both MDC and PDC in blood of healthy subjects, however no precise literature data exist on the number and distribution of BDC in the skin. The aim of our study was to assess the number and distribution of BDC and their subtypes in the healthy skin. The-study included 30 healthy volunteers (age 18-51). Punch biopsies were taken from the buttock skin from each subject, and immunofluorescent staining was performed using monoclonal mouse IgG1 antibodies directed against BDCA-1, BDCA-2, BDCA-3 and BDC-4. The BDC were present both in the epidermis and dermis. PDC were detected mainly in the dermis (mean 1.2 cells per field). Myeloid subtypes were observed mainly in the middle layers of the epidermis and in the upper part of the dermis (mean 1.8 cells per field). The detection of blood dendritic cells in the skin proves their role in immune cutaneous surveillance
