The correlation of SKA2 with cortisol, IL-1β and anxiety in pregnant women with the risk of preterm delivery
Objective The association between preterm birth (PTB), Spindle and Kinetochore Associated Complex Subunit 2 gene (SKA2), cortisol and anxiety have been shown, but in this study, we aimed to clarify whether the expression of the SKA2 gene plays a role in interleukin-1β (IL-1β) level since increasing level of IL-1β is linked with PTB. Methods The case-control study was conducted on 49 and 51 women with preterm and term delivery, respectively. The score of anxiety was ranked according to the Spielberger state trait Anxiety Inventory. The concentration of cortisol and IL-1β was determined by the ELISA method. The expression of SKA2 gene was assessed by the quantitative real time real time polymerase chain reaction (qRT-PCR). The western blot analysis was also performed to confirm the expression of SKA2 at the levels of protein. Results The results showed that the gene/protein expression of SKA2, the concentrations of cortisol and IL-1β were significantly high-er in the preterm than the term group. In the preterm group, the expression of SKA2 was positively correlated to the other factors including cortisol, IL-1β, and the degree of anxiety. Conclusion Our findings suggest that the expression of SKA2 was correlated positively to the levels of cortisol, IL-1β and the rate of anxiety in women with PTB. © 2020 Korean Neuropsychiatric Association
SKA2 gene � A novel biomarker for latent anxiety and preterm birth prediction
Background: There is a relationship between preterm birth (PTB)and anxiety. Spindle and Kinetochore Associated Complex Subunit 2 (SKA2)gene polymorphism (NC000017.11: g.59110368 G > A)has also been associated with the development of anxiety. The current study was designed to evaluate the relationship between SKA2 gene SNP (NC000017.11: g.59110368 G > A)with the occurrence of anxiety and PTB which might be considered a predictive biomarker for the prediction of preterm delivery. Methods: SKA2 gene (SNP rs7208505)genotyping was performed in 300 women with term birth (TB)and 293 women with PTB using PCR-RFLP method and then followed by DNA sequencing. Cortisol level was analyzed with ELISA method and the presence of anxiety was detected using Spielberg Inventory. Results: The AA genotype of SKA2 gene significantly increased the risk of PTB compared to the GG genotype by 9.6 fold (CI4.5�20.2, P A)could be as a predictive biomarker for the risk of PTB. © 2019 Elsevier B.V
Association of grp78, hif-1α and bag3 expression with the severity of chronic lymphocytic leukemia
Introduction: Parallel with the progression of Chronic Lymphocytic Leukemia (CLL), the levels of 78KDa Glucose-Regulated Protein (GRP78) and Hypoxia-Inducible Factor 1 alpha (HIF-1α) are increased as they may activate the induction of anti-apoptotic proteins such as BCL2 Associated Athanogene 3 (BAG3). Previous studies have indicated that there is a positive correlation among GRP78, HIF-1α and BAG3. Objective: This study aimed to evaluate the effect of metabolic factors involved in invasive CLL on apoptotic factors. Methods: A case-control study was conducted on 77 patients diagnosed with CLL along with 100 healthy individuals. Cell blood count was performed for all participants. According to Binet's classification, CLL patients were divided into different groups. B cells were isolated from the peripheral blood of CLL patients by binding to anti-CD19 beads. The expression of BAG3, GRP78 and HIF-1α genes was analyzed using the RT-PCR method. To confirm the results of RT-PCR, western blot analysis was carried out. Results: The results showed that there was a strong association among the expression of BAG3, GRP78 and HIF-1α. The stage of CLL in patients was highly correlated with the expression rate of each gene (p<0.001). Accordingly, the western blot analysis indicated that the concentrations of GRP78 and HIF-1α were significantly higher than the expression of BAG3, considering the stage of CLL. Conclusion: It was shown that increased expression of GRP78 and HIF-1α could result in the elevation of BAG3, as well as the disease progression. Therefore, the role of these metabolic factors might be more pronounced compared with the anti-apoptotic agents to monitor disease progression in CLL patients. © 2020 Bentham Science Publishers
The shift of hbf to hba under influence of ska2 gene; a possible link between cortisol and hematopoietic maturation in term and preterm newborns
Background: We hypothesized that the SKA2 gene can convert hemoglobin F to A leading to the maturity of the hematopoietic system by glucocorticoid hormone; so, the present study aimed to investigate the health outcome of newborns by using the effect of SKA2 gene on hematopoietic matu-ration. Methods: At first, 142 samples were divided into term and preterm. After sampling from the umbilical cord blood, the expression of SKA2 genes and HbA and F were evaluated by quantitative RT-PCR. The blood gases were measured by Campact 3 device. Finally, the cortisol level was measured by ELISA method and HbA and F levels were investigated by capillary electrophoresis. Results: The blood gases and Apgar scores were more favorable in term newborns (P <0.001). Levels of protein/expression of HbF in newborns with Apgar score greater than 7 was lower than that of the newborns with Apgar score below 7 (P <0.001). Cortisol and HbA levels were considerably higher in term newborns compared to the preterm ones (P <0.001). In the preterm and term groups, SKA2 gene expression had a positive and significant relationship with cortisol and HbA levels as well as a nega-tive relationship with the HbF level. In the preterm group, a positive and significant relationship was observed between the expression of SKA2 and HbF genes. Conclusion: The results revealed that the SKA2 gene affected hematopoietic maturation in preterm and term newborns and the health outcome of newborns improved by increasing HbA level. © 2021 Bentham Science Publishers
The use of multi-criteria decision making models in evaluating anesthesia method options in circumcision surgery
HANCERLIOGULLARI KOKSALMIS, GULSAH/0000-0002-2551-541XWOS: 000397523200001PubMed: 28114944Background: Determining the most suitable anesthesia method for circumcision surgery plays a fundamental role in pediatric surgery. This study is aimed to present pediatric surgeons' perspective on the relative importance of the criteria for selecting anesthesia method for circumcision surgery by utilizing the multi-criteria decision making methods. Methods: Fuzzy set theory offers a useful tool for transforming linguistic terms into numerical assessments. Since the evaluation of anesthesia methods requires linguistic terms, we utilize the fuzzy Analytic Hierarchy Process (AHP) and fuzzy Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). Both mathematical decision-making methods are originated from individual judgements for qualitative factors utilizing the pair-wise comparison matrix. Our model uses four main criteria, eight sub-criteria as well as three alternatives. To assess the relative priorities, an online questionnaire was completed by three experts, pediatric surgeons, who had experience with circumcision surgery. Results: Discussion of the results with the experts indicates that time-related factors are the most important criteria, followed by psychology, convenience and duration. Moreover, general anesthesia with penile block for circumcision surgery is the preferred choice of anesthesia compared to general anesthesia without penile block, which has a greater priority compared to local anesthesia under the discussed main-criteria and sub-criteria. Conclusions: The results presented in this study highlight the need to integrate surgeons' criteria into the decision making process for selecting anesthesia methods. This is the first study in which multi-criteria decision making tools, specifically fuzzy AHP and fuzzy TOPSIS, are used to evaluate anesthesia methods for a pediatric surgical procedure
