(Il)Legitimisation of the role of the nation state: Understanding of and reactions to Internet censorship in Turkey

This study aims to explore Turkish citizen-consumers' understanding of and reactions to censorship of websites in Turkey by using in-depth interviews and online ethnography. In an environment where sites such as YouTube and others are increasingly being banned, the citizen-consumers' macro-level understanding is that such censorship is part of a wider ideological plan and their micro-level understanding is that their relationship with the wider global network is reduced, in the sense that they have trouble accessing full information on products, services and experiences. The study revealed that citizen-consumers engage in two types of resistance strategies against such domination by the state: using irony as passive resistance, and using the very same technology used by the state to resist its domination

Heterozygous <em>COL17A1 </em>variants are a frequent cause of amelogenesis imperfecta

\ua9 Author(s) (or their employer(s)) 2023. Re-use permitted under CC BY. Published by BMJ.Background: Collagen XVII is most typically associated with human disease when biallelic COL17A1 variants (&gt;230) cause junctional epidermolysis bullosa (JEB), a rare, genetically heterogeneous, mucocutaneous blistering disease with amelogenesis imperfecta (AI), a developmental enamel defect. Despite recognition that heterozygous carriers in JEB families can have AI, and that heterozygous COL17A1 variants also cause dominant corneal epithelial recurrent erosion dystrophy (ERED), the importance of heterozygous COL17A1 variants causing dominant non-syndromic AI is not widely recognised. Methods: Probands from an AI cohort were screened by single molecule molecular inversion probes or targeted hybridisation capture (both a custom panel and whole exome sequencing) for COL17A1 variants. Patient phenotypes were assessed by clinical examination and analyses of affected teeth. Results: Nineteen unrelated probands with isolated AI (no co-segregating features) had 17 heterozygous, potentially pathogenic COL17A1 variants, including missense, premature termination codons, frameshift and splice site variants in both the endo-domains and the ecto-domains of the protein. The AI phenotype was consistent with enamel of near normal thickness and variable focal hypoplasia with surface irregularities including pitting. Conclusion: These results indicate that COL17A1 variants are a frequent cause of dominantly inherited non-syndromic AI. Comparison of variants implicated in AI and JEB identifies similarities in type and distribution, with five identified in both conditions, one of which may also cause ERED. Increased availability of genetic testing means that more individuals will receive reports of heterozygous COL17A1 variants. We propose that patients with isolated AI or ERED, due to COL17A1 variants, should be considered as potential carriers for JEB and counselled accordingly, reflecting the importance of multidisciplinary care

Toxoplasma gondii infection and liver disease: a case-control study in a Northern Mexican population

<p>Abstract</p> <p>Background</p> <p>Infection with the protozoan parasite <it>Toxoplasma gondii </it>may cause liver disease. However, the impact of the infection in patients suffering from liver disease is unknown. Therefore, through a case-control study design, 75 adult liver disease patients attending a public hospital in Durango City, Mexico, and 150 controls from the general population of the same region matched by gender, age, and residence were examined with enzyme-linked immunoassays for the presence of anti-<it>Toxoplasma </it>IgG and anti-<it>Toxoplasma </it>IgM antibodies. Socio-demographic, clinical and behavioral characteristics from the study subjects were obtained.</p> <p>Results</p> <p>Seroprevalence of anti-<it>Toxoplasma </it>IgG antibodies and IgG titers did not differ significantly in patients (10/75; 13.3%) and controls (16/150; 10.7%). Two (2.7%) patients and 5 (3.3%) controls had anti-<it>Toxoplasma </it>IgM antibodies (<it>P </it>= 0.57). Seropositivity to <it>Toxoplasma </it>did not show any association with the diagnosis of liver disease. In contrast, seropositivity to <it>Toxoplasma </it>in patients was associated with consumption of venison and quail meat. <it>Toxoplasma </it>seropositivity was more frequent in patients with reflex impairment (27.8%) than in patients without this impairment (8.8%) (<it>P </it>= 0.05). Multivariate analysis showed that <it>Toxoplasma </it>seropositivity in patients was associated with consumption of sheep meat (OR = 8.69; 95% CI: 1.02-73.71; <it>P </it>= 0.04) and rabbit meat (OR = 4.61; 95% CI: 1.06-19.98; <it>P </it>= 0.04).</p> <p>Conclusions</p> <p>Seropositivity to <it>Toxoplasma </it>was comparable among liver disease patients and controls. Further studies with larger sample sizes are needed to elucidate the association of <it>Toxoplasma </it>with liver disease. Consumption of venison, and rabbit, sheep, and quail meats may warrant further investigation.</p

Heterozygous COL17A1 variants are a frequent cause of amelogenesis imperfecta

Enhancement of The Behaviour of Laterally Loaded Vertical Piles Embedded in Clayey Soil

One of the most important problems is the construction on a soft clay soil, which extends over many areas in Egypt, Construction on a soft clay soil requires the use of deep foundations. In most of the cases the pile lateral capacity isn\u27t satisfied due to the upper soft clay layers. Thus, there is a need to enhance the lateral load behavior of the pile. This paper is to study the enhancement of the lateral behavior of piles by replacing the upper layers of soft clay with dense sand. A series of laboratory tests were conducted on a single pile in soft clay soil. The upper clay layer around the pile was removed and replaced with compacted dense sand and the tests were repeated. The model pile used in this study was made of smooth hollow steel pipe. The outer diameter and wall thickness were 21 and 1.8 mm, respectively. Results indicated that the improvement of laterally loaded pile behavior was found to be strongly dependent on the replaced layer depth and replaced layer extension around the pile in dense sand. Results of experimental investigations were used to extract the lateral load-lateral displacement (P-Δ) curves
