(BMC , 2021-11-09) Mulenga, James; Mulenga, Mulenga C.; Musonda, Katongo M. C.; Phiri, Chilizani; Phiri, Chilizani; İktisat Bölümü; DMU-6766-2022
Background Health insurance is an essential aspect of healthcare. This is because it enables the insured to acquire timely and essential healthcare services, besides offering financial protection from catastrophic treatment costs. This paper seeks to establish gender differentials and determinants of health insurance coverage in Zambia. Methods The data used in this study was obtained from the 2018 Zambia Demographic and Health Survey. Data were analyzed using STATA 13.0 software and focused on descriptive and Probit regression analyses. Results The study reveals that for women and men, age, wealth category, education, and professional occupation are positively associated with health insurance while being self-employed in the agricultural sector negatively influences health insurance coverage for both sexes. Other variables have gender-specific effects. For instance, being in marital union and having a clerical occupation increases the probability of having health insurance for women while being in the services, skilled, and unskilled manual occupations increases the probability of having health insurance for men. Further, residing in rural areas reduces the probability of having health insurance for men. Conclusion The study concludes that there are differences in factors that influence health insurance between women and men. Hence, this study highlights the need to enhance health insurance coverage by addressing the different factors that influence health insurance coverage among men and women. These factors include enhancing education, job creation, diversifying insurance schemes, and gender consideration in the design of National Health Insurance Scheme.

(Walter De Gruyter Gmbh, 2021-11) Güneş, Sevinç Odabaşı; Akın, Onur; Eray, Şafak; ERAY ÇAMLI, ŞAFAK; Tıp Fakültesi; Çocuk ve Ergen Psikiyatrisi ve Ruh Sağlığı Ana Bilim Dalı; AAG-8101-2021
Objectives: The aim of this study was to evaluate the resilience of girls with central precocious puberty (CPP) during treatment with a gonadotropin-releasing hormone agonist (GnRHa) and compare these results with their healthy peers.Methods: The Connor-Davidson Resilience Scale (CD-RISC) is a self-report scale used to quantify resilience, which is divided into seven subgroups (hardiness, coping, flexibility, purpose, optimism, regulation of emotion and cognition (REC), and self-efficacy). Fifty-one girls with CPP receiving GnRHa treatment and 51 healthy controls were involved in the study. Anthropometric measurements were evaluated and CD-RISC was performed at least six months after the initiation of GnRHa treatment.Results: There was no statistically significant difference between the anthropometric evaluations of girls with CPP and the control group. Similarly, the total score and subgroup scores of patients with CPP and the control group showed no statistically significant difference. In the correlation analysis, there was a weak negative correlation between height and flexibility (r=-0.314 p=0.025), height SDS and flexibility (r=-0.254 p=0.092), height SDS, and purpose (r=-0.285 p=0.058). Also, there was a weak negative correlation between REC and weight (r=-0.435 p=0.003), REC and weight SDS (r=-0.461 p=0.002), REC and height (r=-0.269 p=0.077), REC and height SDS (r=-0.322 p=0.033), REC and BMI (r=-0.289 p=0.058), and REC and BMI SDS (r=-0.353 p=0.019).Conclusions: The resilience of girls with CPP treated with GnRHa was found to be similar to their healthy peers. The early diagnosis of the disease and adequate treatment may decrease the discrepancy of somatic changes between girls with CPP and their peers, which may help them to overcome the stress of CPP and long-term treatment.

Purpose The aim of the study was to investigate the association between serum 25-hydroxyvitamin D status within the last 6 months prior to COVID-19 infection and parameters of immune function and clinical outcomes. Methods Fifty-six patients, who were admitted to the emergency clinic and diagnosed with COVID-19 infection, were included in the study. Data on clinical characteristics, inflammatory parameters and vitamin D status were recorded for each patient. All the participants had data on 25-hydroxyvitamin D status within the last 6 months prior to COVID-19 infection. Results The patients were stratified as those with vitamin D status less than 20 ng/mL and higher than 20 ng/mL. A group with vitamin D status less than 20 ng/mL had lower lymphocyte counts and lower haemoglobin levels that was statistically significant (respectively; p = 0.021, p = 0.035). Higher C-reactive protein (CRP) levels were seen in the vitamin D-deficient group (p = 0.013). It was observed that vitamin D status of the patients who required oxygen therapy were lower than those who did not require oxygen therapy, not statistically significant (p = 0.05). Patients who did not use vitamin D supplementation within 6 months prior to COVID-19 infection had more likely to be diagnosed with pneumonia (p = 0.004). Conclusion Cases with lower vitamin D status had increased inflammatory markers and worse clinical outcomes than patients with higher vitamin D status. This study suggests that vitamin D status can be used as a prognostic factor in COVID-19 patients, and vitamin D supplementation can be recommended to improve the clinical outcomes in COVID-19 infection.
Targeted inhibition of fibroblast growth factor receptor 1-GLI through AZD4547 and GANT61 modulates breast cancer progression
(Frontiers Media Sa, 2021-10-13) Riaz, Syeda Kiran; Khan, Walizeb; Wang, Fen; Khaliq, Tanwir; Malik, Amber; Razia, Eisha Tir; Khan, Jahangir Sarwar; Haque, Shafiul; Hashem, Anwar M.; Alkhayyat, Shadi S.; Azhar, Najiah Esam; Harakeh, Steve; Ansari, Mohammad Javed; Haq, Farhan; Malik, Muhammad Faraz Arshad; Haque, Shafiul; Tıp Fakültesi; 0000-0002-2989-121X; AAN-2946-2020
The underlying mechanism of fibroblast growth factor receptor 1 (FGFR1) mediated carcinogenesis is still not fully understood. For instance, FGFR1 upregulation leads to endocrine therapy resistance in breast cancer patients. The current study aimed to identify FGFR1-linked genes to devise improved therapeutic strategies. RNA-seq and microarray expression data of 1,425 breast cancer patients from two independent cohorts were downloaded for the analysis. Gene Set Enrichment Analysis (GSEA) was performed to identify differentially expressed pathways associated with FGFR1 expression. Validation was done using 150 fresh tumor biopsy samples of breast cancer patients. The clinical relevance of mRNA and protein expression of FGFR1 and its associated genes were also evaluated in mouse embryonic fibroblasts (MEFs) and breast cancer cell line (MDA-MB-231). Furthermore, MDA-MB-231 cell line was treated with AZD4547 and GANT61 to identify the probable role of FGFR1 and its associated genes on cells motility and invasion. According to GSEA results, SHH pathway genes were significantly upregulated in FGFR1 patients in both discovery cohorts of breast cancer. Statistical analyses using both discovery cohorts and 150 fresh biopsy samples revealed strong association of FGFR1 and GLI1, a member of SHH pathway. The increase in the expression of these molecules was associated with poor prognosis, lymph node involvement, late stage, and metastasis. Combined exposures to AZD4547 (FGFR1 inhibitor) and GANT61 (GLI1 inhibitor) significantly reduced cell proliferation, cell motility, and invasion, suggesting molecular crosstalk in breast cancer progression and metastasis. A strong positive feedback mechanism between FGFR1-GLI1 axis was observed, which significantly increased cell proliferation and metastasis. Targeting FGFR1-GLI1 simultaneously will significantly improve the prognosis of breast cancer in patients.

(Pergamon-Elsevier Science Ltd, 2023-12) Ersal, Tuba; Özkocaman, Vildan; Yalçın, Cumali; Orhan, Bedrettin; Candar, Ömer; Çubukçu, Sinem; Koca, Tuba Güllü; Hunutlu, Fazıl Cağrı; Özkalemkaş, Fahir; ERSAL, TUBA; ÖZKOCAMAN, VİLDAN; YALÇIN, CUMALİ; ORHAN, BEDRETTİN; CANDAR, ÖMER; ÇUBUKÇU, SİNEM; GÜLLÜ KOCA, TÛBA; HUNUTLU, FAZIL ÇAĞRI; ÖZKALEMKAŞ, FAHİR; Tıp Fakültesi; İç Hastalıkları; Hematoloji Bölümü; 0000-0003-3970-2344; 0000-0002-4991-9830; AAJ-4354-2021; JJP-2815-2023; KIE-5102-2024; ACW-2157-2022; JWF-3713-2024; JJB-0254-2023; GWQ-5007-2022; KCK-7512-2024; JJW-7463-2023
Introduction: The standard approach for allogeneic stem cell transplantation (allo-SCT) is to administer donor cells on the same day as a fresh product to a patient who has been given a preparative regimen. The difficulty in collecting and transporting donor cells, especially during the COVID-19 pandemic, has made it essential to collect and cryopreserve the grafts before the recipient begins the transplant preparation regimen. However, the shortand long-term impacts of cryopreservation on transplant outcomes remain controversial. Materials and methods: This retrospective study included 93 patients who underwent allo-SCT between January 2012 and August 2022 at the Stem Cell Transplant Unit of Bursa Uludag University Faculty of Medicine using frozen and fresh products of peripheral blood stem cells from a fully matched sibling donor. The effect of cryopreservation of donor grafts on engraftment kinetics was investigated. Results: Frozen and fresh products were used in 37 and 56 patients, respectively. The majority of patients had acute myeloid leukemia and acute lymphoblastic leukemia. The median age at transplantation was 41 years. Neutrophil engraftment time was similar between the two groups (median: 14 vs. 16 days, p = 0.393). Platelet engraftment time was longer in the frozen product group (median: 12 vs. 15 days, p < 0.001). There was no statistically significant difference between freezing time and viability. The acute graft-versus-host disease (GVHD) rate was 37.8 % in the frozen product group and 28.6 % in the fresh product group (p = 0.349). There was no significant difference between the two groups in terms of primary and secondary graft failure, chronic GVHD, 30-day chimerism, relapse, overall survival, progression-free survival, and nonrelapse mortality. Conclusion: Having donor cells ready before transplantation significantly prevents donor-induced adverse events and provides confidence and practicality to both the clinician and the recipient. Allo-SCT with frozen products is a successful method that can be safely applied, especially when disruptions in donor-derived cell collection or transportation are foreseen.

Objective: To investigate the shape differences in the putamen of early-onset Parkinson's patients compared with healthy controls and to assess and to assess sub-regional brain abnormalities. Methods: This study was conducted using the 3-T MRI scans of 23 early-onset Parkinson's patients and age and gender matched control subjects. Landmark coordinate data obtained and Procrustes analysis was used to compare mean shapes. The relationships between the centroid sizes of the left and right putamen, and the durations of disease examined using growth curve models. Results: While there was a significant difference between the right putamen shape of control and patient groups, there was not found a significant difference in terms of left putamen. Sub-regional analyses showed that for the right putamen, the most prominent deformations were localized in the middle-posterior putamen and minimal deformations were seen in the anterior putamen. Conclusion: Although they were not as pronounced as those in the right putamen, the deformations in the left putamen mimic the deformations in the right putamen which are found mainly in the middle-posterior putamen and at a lesser extend in the anterior putamen.

Background: Skincare products and cosmetic procedures are used as an adjunct or complementary to conventional drug therapy for acne vulgaris (AV). Objective: To evaluate the use of skincare products and the frequency of cosmetic procedures in AV treatment. Methods: A total of 1,755 patients with AV completed the survey prepared by the researchers and the Cardiff Acne Disability Index (CADI) questionnaire. The clinical findings and the Food and Drug Administration (FDA) severity scores were recorded by the dermatologists. Results: For AV, 66.7% of the patients stated that they used skincare products and 26.7% had undergone cosmetic procedures. The use of skincare products was statistically significantly higher in women (female: 74.5%, male: 57.7%, p < 0.0001); older people (users: 22 ± 7.6years, non-users: 21.2 ± 5.7 years, p < 0.0001); patients with a higher CADI score (users: 7 ± 3.7, non-users: 6.9 ± 4.3, p = 0.010); FDA severity score 2 and 3 (FDA-1: 58.1%; FDA-2: 72.4%, FDA-3: 73%, FDA-4: 67%, p < 0.0001); long-term disease (users: 57 ± 43 months; non-users: 47.7 ± 42.3 months, p < 0.0001); facial involvement (present: 70.2%, absent: 51.4%, p = 0.017); high income levels (users: 73.5%; non-users: 26.5%, p = 0.001); and graduate or post-graduate degrees (undergraduate≤%62.8, graduate≥%76.8, p < 0.0001). The rate of cosmetic procedures was higher in those with higher CADI scores (users: 7.8 ± 3.8; non-users: 7.1 ± 3.96, p < 0.0001); older patients (users: 22.7 ± 10.7 years; non-users: 21.3 ± 5 years, p < 0.0001); high school (25.6%); and graduate (28.9%) education (p = 0.043), those with lower disease severity (FDA-1: 31.1%; FDA-2: 28.5%, FDA-3: 27.1%, FDA-4: 20.4%, p = 0.022); smokers (smokers: 32.5%; non-smokers: 25.5%, p = 0.020), and those with AV in the family (present: 29.8%; absent: 24.2%, p = 0.009). The patients most frequently used cleansers (85.2%) as cosmetic products, and most commonly underwent skincare treatment (71%) as an interventional procedure. They mostly learned about such products and methods from the Internet, and 33.3% of the participants had undergone procedures performed by non-physicians. Conclusion: The patients generally choose skincare products as a result of their Internet search and sometimes have these procedures performed by non-physicians. Dermatologists should be aware of this situation and inform their patients about appropriate products and procedures.
Anti-cancer effect of metformin on the metastasis and invasion of primary breast cancer cells through mediating NF-kB activity
(Elsevier, 2021-05) Yenmiş, Güven; Saraç, Elif Yaprak; Besli, Nail; Soydaş, Tuğba; Taştan, Cihan; Kançağı, Derya Dilek; Yılancı, Muhammet; Şenol, Kazım; Karagülle, Onur Olgaç; Ekmekçi, Cumhur Gökhan; Ovalı, Ercüment; Tunçdemir, Matem; Ulutin, Turgut; Sultuybek, Gönül Kanıgür; Tıp Fakültesi; Göğüs Cerrahisi Ana Bilim Dalı; 0000-0002-1575-5751; GUP-5057-2022
Current evidence strongly suggests that aberrant activation of the nuclear factor kappa B (NF-kB) signaling cascade is connected to carcinogenesis. The matrix metalloproteinases (MMP) which are also the key agents for tumor metastasis may be potent candidates for tumor diagnosis in clinics. In this in vitro study, we hypothesized that metformin with an effective dose can inhibit tumor cell proliferation and metastasis by modulating the expressions of MMP-2 and 9 and interfering with NF-kB signaling in primary breast cancer cells (PBCCs). 300 000 cells per ml were obtained from biopsies of breast tumors from five human donors. The cell viability and proliferation were tested. Immunocytochemistry was performed for MMP 2, MMP 9, and NF-kB, and enzyme-linked immunosorbent assay for NF-kB activity, quantitative real-time PCR for RELA/p65, IkBa, MMP-2, and MMP 9. Three different doses of metformin (5, 10, and 25 mM) (Met) reduced the viability and proliferation of PBCCs in a dose-dependent manner, maximum inhibition was observed at 25 mM Met. The expression of RELA/p65 was not affected by 25 mM Met. Nuclear immunoreactivity and activity of NF-kB reduced while cytoplasmic NF-kB (p65) elevated by 25 mM Met compared to non-treatment (P < 0.05). The expression and immunoreactivity of MMP 9 but not MMP 2 were decreased by 25 mM Met treatment, compared with the non-treatment (P < 0.05). Metformin may have an essential antitumor role in the invasion and metastasis pathways of PBCCs by downregulating the MMP 9 expression blocking both the activity and nuclear translocation of NF-kB.
Examination of facial convexity and concavity values with reference to the external acoustic pore: A retrospective study
(Lippincott Williams & Wilkins, 2023-05) Çini, Nilgün Tuncel; Babacan, Serdar; Sak, Nazan Güner; Işıklar, Sefa; Arı, İlknur; Gökalp, Gökhan; IŞIKLAR, SEFA; ARI, İLKNUR; GÖKALP, GÖKHAN; Sak, Nazan Güner; Tıp Fakültesi; 0000-0002-2070-5193; HNN-1671-2023; AAK-3779-2021; ELI-9107-2022; GMO-0473-2022
The human skull serves as an essential material for facial reconstruction. In particular, the petrous part of the temporal bone is vital due to its compact structure, which can resist mechanical forces. The study aims to give descriptive values to estimate the face shape and produce regression formulas through the external acoustic pore as a reference point. The study was carried out on 3-dimensional computed tomography images, a total of 83 adult images (45 females and 38 males) in the Department of Radiology of Bursa Uludag University Medical Faculty. The distances between the imaginary vertical line passing through the porion and the anthropometric points revealing the facial features were measured for the soft and hard tissue. The vertical distances between the soft and hard tissue landmarks were also measured for both sexes. Measurements were performed with the Image J program, and for the statistical analysis, SPSS 25.0 was used (P < 0.005). Linear simple regression analysis was used to produce formulas to estimate the soft tissue thickness using hard tissue. Also, discriminant function analysis was performed to determine sex in the presence of an unknown skull. The descriptive values of the variables on the axial and vertical planes and the differences between sexes are given. Also, all formulas make accurate predictions of 90% or more. The authors tried to estimate the anatomical points that roughly reveal the facial features with the regression formulas developed using anthropometric measurements. The authors think that the shape of the face, which is more specific to the individual, can be reached more clearly using mathematical models, and the authors believe that this study will set an example for future studies.

(Elsevier, 2023-10) Abay, Merve; Özgen, Levent; Yalçın, Yakup; Özerkan, Kemal; ABAY, MERVE; ÖZGEN, LEVENT; YALÇIN, YAKUP; ÖZERKAN, KEMAL; Tıp Fakültesi; Kadın Hastalıkları ve Doğum Ana Bilim Dalı; 0000-0003-0070-2646; CAK-3842-2022; JFT-0660-2023; HQP-3191-2023; AAH-9791-2021
Objective: Serous tubal intraepithelial carcinoma (STIC) is a precursor lesion which is located in the distal fallopian tube and causes high grade serous ovarian carcinoma (HGSOC). The incidence of STIC for women underwent risk reducing salpingo-oophorectomy for BRCA mutation varies from 0.6 to 7% and its clinical outcomes are still unclear. The aim of this study was to demonstrate the incidence of STIC and HGSOC in BRCA1/2 mutation carriers after risk reducing salpingo-oophorectomy (RRSO) and the clinical outcomes of these patients. Material and methods: We retrospectively reviewed the records of 48 BRCA1 and/or 2 mutation carriers who underwent prophylactic salpingo-oophorectomy with or without hysterectomy at the Department of Obstetrics and Gynecology, Bursa Uludag University between January 2000 and January 2022. Inclusion criteria: BRCA 1 and/or 2 mutation carriers diagnosed by genetic testing, asymptomatic patients with no abnormal findings on pelvic examination. Exclusion criteria: patients with no abnormal findings on pelvic examination and a presence of a personal history of ovarian, fallopian tube or peritoneal cancer. Results: A total of 48 BRCA 1 and/or 2 mutation carriers underwent RRSO. STIC was diagnosed in 1 (2,0%) patient and restaging surgery was not performed. Primary peritoneal carcinoma (PPC) did not develop during the 20 months follow-up period. One (2.0%) patient was diagnosed with occult ovarian cancer. Restaging surgery was performed and chemotherapy treatments were given after surgery. A pelvic recurrence developed 25 months after the occult cancer diagnosis in the follow up period. One (2.0%) patient with normal histopathological findings after RRSO was diagnosed with peritoneal cancer 57 months after the operation. Conclusion: The risk of PPC continues after RRSO. Therefore, close follow-up procedure is very important for early diagnosis and effective treatment of patients with PPC after RRSO.
Flavobacterium turcicum sp. nov. and Flavobacterium kayseriense sp. nov. isolated from farmed rainbow trout in Turkey
(Elsevier, 2021-02) Satıcıoğlu, İzzet Burçin; Ay, Hilal; Altun, Soner; Duman, Muhammed; Şahin, Nevzat; ALTUN, SONER; DUMAN, MUHAMMED; Veteriner Fakültesi; Su Ürünleri Hastalıkları Ana Bilim Dalı; 0000-0001-9096-875X; 0000-0001-7707-2705; AAG-8518-2021; T-1697-2019
During a study on culturable microorganisms from fish farms, four yellow-pigmented gram negative, rod shaped isolates, F-47(T), F-339(T), F-380 and F-400, were recovered from rainbow trout samples exhibiting clinical signs. Based on 16S rRNA gene sequence analysis, the strains were identified as members of the genus Flavobacterium. Strains F-47(T) and F-380 shared the highest 16S rRNA gene sequence identity level of 97.6% with the type strain of Flavobacterium frigoris DSM 15719(T) while strains F-339(T) and F-400 shared the highest identity level of 97.6% with the type strain of F. caseinilyticum AT-3-2(T). A polyphasic taxonomic approach including phenotypic and genomic characterization as well as whole-cell MALDI-TOF mass spectrometry analyses was employed to ascertain the taxonomic position of the strains within the genus Flavobacterium. Digital DNA-DNA hybridization (dDDH) and average nucleotide identity (ANI) analyses between strains F-47(T), F-339(T) and their close neighbours F. frigoris DSM 15719(T) and F. caseinilyticum AT-3-2(T), respectively, confirmed that both strains represent novel species in the genus Flavobacterium. The DNA G+C contents of the strains F-47(T) and F-339(T) are 34.3% and 35.3%, respectively. It can be concluded on the basis of polyphasic characterization as well as pairwise genome comparisons that the strains F-47(T) and F-339(T) represent two novel species within the genus Flavobacterium, for which Flavobacterium kayseriense sp. nov. F-47(T) (=JCM 34195(T)=KCTC 82255(T)) and Flavobacterium turcicum sp. nov. F-339(T) (=JCM 34202(T)=KCTC 82262(T)) are proposed, respectively.

Plants of the genus Brassica occupy the top place among vegetables in the world. This genus, which contains a group of six related species of a global economic significance, three of which are diploid: Brassica nigra (L.) K. Koch, Brassica oleracea L., and Brassica rapa L. and three are amphidiploid species: Brassica carinata A. Braun, Brassica juncea (L.) Czern., and Brassica napus L. These varieties are divided into oily, fodder, spice, and vegetable based on their morphological structure, chemical composition, and usefulness of plant organs. The present review provides information about habitat, phytochemical composition, and the bioactive potential of Brassica plants, mainly antioxidant, antimicrobial, anticancer activities, and clinical studies in human. Brassica vegetables are of great economic importance around the world. At present, Brassica plants are grown together with cereals and form the basis of global food supplies. They are distinguished by high nutritional properties from other vegetable plants, such as low fat and protein content and high value of vitamins, fibers along with minerals. In addition, they possess several phenolic compounds and have a unique type of compounds namely glucosinolates that differentiate these crops from other vegetables. These compounds are also responsible for numerous biological activities to the genus Brassica as described in this review.

Objective: The glenopolar angle is a helpful criterion for recommending operative treatment. This study aims to determine the morphometric features of the scapula and provide essential information that supplies scapular biomechanics to produce a formula.Methods: The study was carried out on 34 dry scapulae in the laboratory of the Anatomy Department of the Faculty of Medicine, Bursa Uludag University. We used calipers for the linear measurements and the ImageJ program for the area and angle parameters. A total of 23 parameters were evaluated in the study. Statistical analyzes were performed using SPSS 22.0 software. Results: According to the results of the correlation analysis, the highest correlation value of (R=0.957) was found to be the distance between the superior angle (angulus superior)-top of the glenoid plane and the inferior angle (angulus inferior)-the top of the glenoid plane. To estimate the glenopolar angle, we applied linear regression analysis and developed the following formula: Glenopolar angle =115.589 - (6.401 x the distance between the coracoid process and the top of the glenoid cavity) - (0.368 x angle between the glenoid plane and the lateral edge of the scapula extending towards the endpoint of the glenoid plane) (Adjusted R2=0.667).Conclusions: Glenopolar angle can provide information about the fracture risk of the glenoid cavity and allows orthopedic surgeons to make quick decisions about the risk in the region. We believe that the study will provide a different perspective on designing different products in industrial designs for shoulder joints, especially in implantations.

COVID-19 pandemic has re-raised questions about healthy housing and residential environments. The aim of this study is to examine lifestyle changes during the pandemic and their reflections in the use of housing. The study also compares households on different socioeconomic levels in Bursa, the study area. Bursa is a Turkish metropolis that was affected by the spread of COVID-19. Data were collected from 500 residents of 30 neighborhoods in the city's three most populous districts, Osmangazi, Nilufer and Yildirim. The participants were selected using stratified sampling and interviewed face-to-face using questionnaires. Reliability analysis, frequency distributions, descriptive statistics, ANOVA and the chi-squared test were used to evaluate the data. The results indicate that the participants' hygiene habits, shopping behaviors, transportation habits and frequency of their contact with neighbors and friends have changed. Most of the participants live in apartments, and they need flexible designs that can be used for different purposes. They need toilets and ventilation spaces at the entrances of their homes. The use of balconies has increased. During the pandemic, the use of urban green spaces decreased in general, and the use of open areas around homes increased. High-income residents have advantages in terms of lifestyle, housing and residential environments, so their awareness about and observance of pandemic rules were higher. Lifestyles, housing, residential environments and urban opportunities differ as a result of socioeconomic segregation, and lower-income residents are more vulnerable to disease. Future studies should consider potential risks to humanity in order to address the housing-related problems of disadvantaged groups.

Irisin, an exercise-induced myokine, has been shown to have a peripheral vasodilator effect. However, little is known about the mechanisms underlying its effects. In this study, it was aimed to investigate the vasoactive effects of irisin on rat thoracic aorta, and the hypothesis that voltage-gated potassium (KV) channels, ATPsensitive potassium (KATP) channels, small-conductance calcium-activated potassium (SKCa) channels, largeconductance calcium-activated potassium (BKCa) channels, intermediate-conductance calcium-activated potassium (IKCa) channels, inward rectifier potassium (Kir) channels, and two-pore domain potassium (K2P) channels may have roles in these effects. Isometric contraction-relaxation responses of isolated thoracic aorta rings were measured with an organ bath model. The steady contraction was induced with both 10-5 M phenylephrine and 45 mM KCl, and then the concentration-dependent responses of irisin (10-9-10-6 M) were examined. Irisin exerted the vasorelaxant effects in both endothelium-intact and -denuded aortic rings at concentrations of 10-8, 10-7, and 10-6 M (p < 0.001). Besides, KV channel blocker 4-aminopyridine, KATP channel blocker glibenclamide, SKCa channel blocker apamin, BKCa channel blockers tetraethylammonium and iberiotoxin, IKCa channel blocker TRAM-34, and Kir channel blocker barium chloride incubations significantly inhibited the irisin-induced relaxation responses. However, incubation of K2P TASK-1 channel blocker anandamide did not cause a significant decrease in the relaxation responses of irisin. In conclusion, the first physiological findings were obtained regarding the functional relaxing effects of irisin in rat thoracic aorta. Furthermore, this study is the first to report that irisin-induced relaxation responses are associated with the activity of KV, KATP, SKCa, BKCa, IKCa, and Kir channels.

(Elsevier Science, 2021-12) Sınmaz, Tuğba; Akansel, Neriman; AKANSEL, NERİMAN; Sağlık Bilimleri Fakültesi; Hemşirelik Bölümü; CAQ-5054-2022
Purpose: The descriptive study was performed to assess patients' pain experienced in the early postoperative period of a lumbar disc herniation surgery and their satisfaction with the pain management administered. Design: This was a descriptive and cross-sectional study conducted from May 8 to November 8, 2017. Methods: Data collection was performed during interviews through the Patient Information Form (20 questions), Turkish version of clinical quality indicators in the Postoperative Pain Management questionnaire (19 questions). The questionnaire included 14 items and 3 subdimensions named nursing interventions, pain management, and the environment. The remaining 5 questions were related to pain management satisfaction and pain severity. Questionnaire items scored on a 1 to 5 Likert scale. The higher the total score obtained from the questionnaire is the satisfaction with pain management increases. Findings: The mean score obtained from the total questionnaire was 51.4 (standard deviation: 6.6). Characteristics of patients with lumbar disc herniation did not influence the total score obtained from the instrument and its sub-dimensions (P .05). Overall satisfaction with pain management was high (mean: 8.3; standard deviation: 1.6) on the 0 to 10 visual analog scale. There was a statistically significant difference between the length of hospital stay, the type of anesthesia used, having more pain than expected, and the satisfaction score of patients (P < .05). As the length of procedure increases, the average and current pain scores increase as well (P < .05). Conclusions: Results of this study indicate that despite pain experienced after the lumbar disc herniation surgery, patients' satisfaction with pain management was high. Encouraging nurses to implement systematic and evidence-based practices in pain management may help alleviate patients' pain after surgery and reduce variety of pain management practices among nurses.

Hypoparathyroidism is an orphan disease with ill-defined epidemiology that is subject to geographic variability. We conducted this study to assess the demographics, etiologic distribution, treatment patterns and complication frequency of patients with chronic hypoparathyroidism in Turkey. This is a retrospective, cross-sectional database study, with collaboration of 30 endocrinology centers located in 20 cities across seven geographical regions of Turkey. A total of 830 adults (mean age 49.6 +/- 13.5 years; female 81.2%) with hypoparathyroidism (mean duration 9.7 +/- 9.0 years) were included in the final analysis. Hypoparathyroidism was predominantly surgery-induced (n = 686, 82.6%). The insulting surgeries was carried out mostly due to benign causes in postsurgical group (SG) (n = 504, 73.5%) while patients in nonsurgical group (NSG) was most frequently classified as idiopathic (n = 103, 71.5%). The treatment was highly dependent on calcium salts (n = 771, 92.9%), calcitriol (n = 786, 94.7%) and to a lower extent cholecalciferol use (n = 635, 76.5%) while the rate of parathyroid hormone (n = 2, 0.2%) use was low. Serum calcium levels were most frequently kept in the normal range (sCa 8.5-10.5 mg/dL, n = 383, 46.1%) which might be higher than desired for this patient group. NSG had a lower mean plasma PTH concentration (6.42 +/- 5.53 vs. 9.09 +/- 7.08 ng/l, p < 0.0001), higher daily intake of elementary calcium (2038 +/- 1214 vs. 1846 +/- 1355 mg/day, p = 0.0193) and calcitriol (0.78 +/- 0.39 vs. 0.69 +/- 0.38 mcg/day, p = 0.0057), a higher rate of chronic renal disease (9.7% vs. 3.6%, p = 0.0017), epilepsy (6.3% vs. 1.6%, p = 0.0009), intracranial calcifications (11.8% vs. 7.3%, p < 0.0001) and cataracts (22.2% vs. 13.7%, p = 0.0096) compared to SG. In conclusion, postsurgical hypoparathyroidism is the dominant etiology of hypoparathyroidism in Turkey while the nonsurgical patients have a higher disease burden with greater need for medications and increased risk of complications than the postsurgical patients.
Effects of sintering time on translucency and color of translucent zirconia ceramics
(Wiley, 2021-06) Durkan, Rukiye; Şimşek, Hatice; Gökay, Gonca Deste; Yılmaz, Burak; Diş Hekimliği Fakültesi; Protetik Diş Tedavisi Ana Bilim Dalı; 0000-0002-5481-0063; AAM-7219-2020
Objective To investigate the effect of sintering time on translucency and color of translucent zirconia ceramics.Materials and Methods Sixty translucent zirconia (5Y-TZP) specimens (12 x 1.6 mm, Katana (KAT) and NexxZr (NEX)) were divided into six groups (n = 10) according to sintering time; 1, 2 (specified by manufacturer-control), and 3 hs. Color differences (Delta Eab) within same material when sintered using different times and between materials when same sintering time was used were calculated, as well as translucency parameters (TP) after the use of each sintering time. Data for Delta Eab and TP were analyzed with two-way ANOVAs, pairwise comparisons, and Fisher's LSD Test (Post-hoc).Results When 1 or 3 h were used, color difference from the color of specimens when manufacturer-specified time (2 h) was used was similar for both KAT and NEX. Delta Eab values of NEX were significantly higher than KAT when sintered for 1 or 3 h (P < 0.001). TP increased for KAT when sintered for 1 h, and was higher than NEX. TP for NEX increased when sintered for 3 h (P < 0.001), but was not significantly different than that of KAT.Conclusions Effect of 1 or 3-h sintering on color was similar for both zirconias. For NEX, this effect resulted in greater differences from the color of specimens when manufacturer-specified time was used. Sintering for 1 h increased the translucency of KAT.Clinical Significance When high translucency is desired, clinicians may prefer 1-h sintering for KAT zirconia. When lower translucency is desired, 3-h sintering for NEX can be used. However, for NEX, the color after 1- or 3-h sintering was different than the color obtained with manufacturer-specified time, and this difference may affect the final color of restoration compared to the final color when manufacturer-specified time is used.

Olive (Olea europaea L.) is one of the most economically important crop from east to the west around the world. The aim of this research was to investigate the genetic relationship among 41 olive genotypes, including 11 well-known Turkish cultivars and 30 Azerbaijani olive genotypes using simple sequence repeat (SSR) markers. In this study, 19 SSR markers were amplified 115 polymorphic SSR alleles. The number of polymorphic alleles ranged from 3 to 10 with an average of 6.05. The observed heterozygosity (Ho) varied from 0.05 to 0.93 with an average of 0.63 and expected heterozygosity (He) differed from 0.26 to 0.86 with an average of 0.72. The polymorphism information content (PIC) ranged from 0.23 to 0.85 with a mean of 0.68. A UPGMA cluster analysis grouped olive genotypes into two distinct clusters and both clusters were divided into two subgroups. Similarly, STRUCTURE analysis assigned olive genotypes into two different gene pools (K = 2) and four gene pools were identified representing the two subgroups by STRUCTURE analysis for K = 4. The genetic similarity of olive genotypes ranged from 0.36 to 0.95. These results revealed that there was a high genetic variation among 30 Azerbaijani olive genotypes. 'Ayvalik 1'and 'Ayvalik 2' from Azerbaijani olive genotypes were different from Turkish local olive cultivar, "Ayvalik" indicating homonymy. This research also highlighted that Azerbaijani olive genotypes were totally distinct from Turkish olive cultivars demonstrating that these olive genotypes might have been imported to Azerbaijan from different countries other than Turkey. The outcomes of this study indicated that these diverse olive genotypes could be useful for development of new olive varieties in Azerbaijan and future breeding programs between two countries could be enhanced by means of these results.

Multiple sclerosis (MS) is an inflammatory, autoimmune demyelinating, and neurodegenerative disorder of the central nervous system. Interactions between environmental factors, predisposition genes, and determining genes appear to be involved in its etiology. Epigenetic mechanisms such as microRNA-mediated gene regulation can determine the susceptibility and severity of autoimmune diseases. Therefore, to determine the role of miR-146a and miR-155 in MS and its developmental stages, the expression levels in the serum of MS and clinically isolated syndrome (CIS) patients were compared with those of healthy controls. In the present study, the expression levels of miR-146a and miR-155 were assessed using quantitative Real-Time PCR in blood samples of 15 CIS patients and 61 relapsing-remitting multiple sclerosis (RRMS) patients alongside 32 healthy patients as controls. Furthermore, any associations with the clinicopathologic variables of the patients were also evaluated. Dysregulations were found only in the miR-146a and miR-155 expressions in the RRMS-Control group. When the RRMS patients were evaluated in terms of the characteristics of sex, annual attack rate, age of diagnosis, duration of follow-up, and immunomodulatory treatments used, no significant differences were observed. However, significant dysregulations were identified in miRNA expression in the vitamin D level, EDSS values, and the number of attacks. ROC curve analysis showed that miR-146a and miR-155 were significant in the RRMS-Control group for the area under the curve (AUC). It is possible that miR-146a may be associated with vitamin D deficiency and disease disability, while miR-155 may be associated with the number of attacks.
