Hybrid EEFIT mission to february 2023 Kahramanmaraş earthquake sequence
The southwestern part of Türkiye was hit on 6 February 2023 by an Mw 7.8 (epicentre:Pazarcık) and then an Mw 7.5 earthquake (epicentre: Elbistan). The event was followed by tensof thousands of aftershocks including the Mw 6.3 event on 20 February (epicentre: Uzunbağ).This paper reports on the preliminary findings of the mission organised by the UK’s EarthquakeEngineering Field Investigation Team (EEFIT) to the Kahramanmaraş Earthquake sequence ofFebruary 2023. This mission followed a hybrid model, combining field and remote investigationtechniques, to investigate the characteristics of the earthquake sequence, its impact on buildingsand infrastructure, as well as the efficacy of relief, response and recovery operations. The keymessages include that the building stock is hard to categorise which brings along difficulties withdamage assessment, that the recovery and reconstruction require multi-sectoral engagement ofkey stakeholders, and that the auditing and quality control mechanisms within the constructionindustry need revisiting in the way forward for better disaster resilience in Türkiye
In vitro evaluation of the microhardness of bovine enamel exposed to acid solutions after bleaching
Effect of bleaching on sound enamel and with early artificial caries lesions using confocal laser microscopy
Microcomputerised tomography evaluation of 10% carbamide peroxide applied to enamel
Objectives. There is still some controversy in the dental literature whether carbamide peroxide bleaching causes demineralization of teeth. One of the reasons for this controversy is that there is as yet no reliable, non-destructive in vitro metod for assessing mineral loss in bleached teeth. The objective of this study was to investigate the possible demineralization effect of 10% carbamide peroxide bleaching agent on enamel and dentine non-destructively

Papillon-Lefevre syndrome - Analysis of peripheral blood lymphocyte subsets
We have studied the peripheral blood lymphocyte populations in our 6 patients (2 female and 4 male) with a mean age of 11.19 with Papillon-Lefevre Syndrome (PLS) using adequate monoclonal antibodies and double coloured flow cytometry. Total B, T, CD4, CD8, CD29, CD45RA, NK, HLA-DR cells were studied. Total B, T, CD4 and CD8 lymphocytes were within normal limits. We have observed an increase in the CD29 lymphocytes and NK cells and a decrease in CD45RA lymphocytes. We think that these findings are important in explaining B lymphocyte activation and in the pathogenesis of the PLS
Clinical and immunological findings in 2 siblings with Papillon-Lefevre syndrome
RAPID AND SEVERE DESTRUCTION Of periodontal tissues in early childhood has been reported both in systemically healthy children and in children with systemic disorders. In this study, the clinical and immunological findings of two siblings in a family with Papillon-Lefevre syndrome are presented. The peripheral blood lymphocytes were analyzed using a double colored flow cytometry and adequate monoclonal antibodies to CD2, CD3, CD4, CD5, CD8, CD11b, CD16, CD19, and HLA-DR receptors. CD11b expression was found to be higher in both siblings (35% and 37%). The elevated CD11b expression may be related to a defect in neutrophils. The expression of natural killer cells was found to be higher in one patient but the results were in normal range. The CD2+, CD3+, CD4+, CD5+, CD8+, and CD19+ lymphocytes were in normal range in both patients. We think that the depressed chemotaxis of peripheral neutrophils, and higher expression of HLA-DR and CD11b molecules in peripheral leukocytes were useful in explaining the pathogenesis of the Papillon-Lefevre syndrome
Generalized prepubertal periodontitis - A report of 4 cases with the immunological findings
The clinical and immunological data from 4 patients with generalized prepubertal periodontitis are presented. The peripheral blood neutrophil chemotaxis taxis was measured using zymosan activated sera as the chemoattractant. All of the 4 patients have shown depressed neutrophil chemotaxis compared to those of the healthy controls. Peripheral blood lymphocyte subpopulations were analysed by double-coloured flow cytometry using monoclonal antibodies for the receptors CD2, CD3, CD4, CD8, CD19, CD29, CD45RA+, 34,29dK, CD56, CD11b/CD18. Lymphocytes bearing CD3 receptors showed a significant decrease compared to those of the controls. Natural killer cells were lowered in 3 of the 4 cases. All of the patients showed a higher increase in CD11b/CD18 expression. The evaluation of CD11b/CD18 receptor in peripheral blood leukocytes may be of help explaining the role uf neutrophils in the pathogenesis of the disease
