    Corchorus olitorius L. (Jute) leaf and seed extracts exerted high antibacterial activity against food and plant pathogenic bacteria
    (2022) Iseri, Ozlem Darcansoy; Korpe, Didem Aksoy; Sahin, Feride Iffet; Cabi, Evren; Haberal, Mehmet; 0000-0002-3462-7632; AAJ-8097-2021
    Aim of this study was to comparatively evaluate antibacterial activities of methanol (MetOH), acetone (Ace), petroleum ether (PE) and aqueous (dw) leaf (L), root (R), and seed (S) extracts of Corchorus olitorius L. on both food- and plant-borne pathogens, with DPPH radical scavenging activities (DRSA), and quantitative and qualitative constituent analysis. Leaf PE has the highest strain susceptibility on both food- and plant-borne pathogens. Clavibacter michiganensis, Pseudomonas tomato, and Erwinia caratovora were susceptible to nearly all the leaf and seed extracts. Very low minimum inhibitory concentration (8-128 mL(-1)) and minimum bactericidal concentration (32-2048 mu g mL(-1)) were determined for both leaf and seed extracts against C. michiganensis. Total phenolic contents were correlated to DRSA. The phenolic compounds tested were higher in the leaf MetOH, cholorogenic acid being the most abundant one. Palmitic acid was determined in leaf PE and seed PE extracts. Results presented here demonstrate high antibacterial activity of C. olitorius leaf seed extracts against phytopathogens for the first time, and provide the most comprehensive data on the antibacterial activity screening against food-borne pathogens. Considering limitations in plant disease control, antibacterial activities of these extracts would be important in plant disease control.

    MLPA Method does not Always Confirm the Results of aCGH: A Study of KANSL1 Gene Deletion Patients
    (2022) Dincer, Selin Akad; Celik, Zerrin Yilmaz; Erol, Ilknur; Sahin, Feride Iffet; AAC-8356-2020
    Background: Microdeletion and microduplications are detected on chromosomes as a pathological subgroup of copy number variants of DNA. It has become easierto identify such chromosomal syndromes after use of array-based comparative genomic hybridization technology. One of them is the 17q21.31 microdeletion and microduplication syndrome. A 500-650 kb sized copy loss on 17q21.31 results in a phenotype which was described as Koolen-de Vries Syndrome including mental retardation, epilepsia, hypotonia and characteristic facial features. Today, we know that haplo-insufficiency of KANSL1 gene located in this region is responsible for these findings. A total of 30 patients with KANSL1 deletion detected during aCGH analyses were enrolled in the current study. All patients were analyzed by Multiplex Ligation-Dependent Probe Amplication (MLPA) method in order to confirm the results. Results: Three of the 30 patients had KANSL1 gene deletion detected by both methods and duplication was found in one patient. Conclusion: As a result of the study, we concluded that although new generation molecular methods enable us to obtain big and valuable data, each method has its own limitations and confirming the reults with another method increases test reliability. Using together of these methods are useful for the geneticists during diagnosis, clinical assessment and genetic counseling of patients.

    (2022) Onder, Esra Nagehan Akyol; Ozcan, Kudret Ebru; Sahin, Feride Iffet; Gulleroglu, Kaan Savas; Baskin, Esra; 35006379
    Familial Mediterranean fever (FMF) is an autoinflammatory disease characterized by recurrent attacks of fever and serositis. Diagnosis is made according to clinical findings and supported by genetic analysis. The most commonly used adult diagnostic criteria are the Tel-Hashomer criteria. Pediatric criteria for FMF diagnosis were described in 2009, but their reliability should be supported by additional reports. In this study, we aimed to compare the pediatric criteria and the Tel-Hashomer and 2019 Eurofever/PRINTO classification criteria using our FMF cohort. A total of 113 patients diagnosed with FMF were included. Demographic features and laboratory findings were retrospectively collected from the patients' files. The patients were evaluated with the Tel-Hashomer, pediatric and Eurofever/PRINTO classification criteria. At least two of five new pediatric criteria were as sensitive (89%) and specific (85%) as the Tel-Hashomer criteria (sensitivity 70%, specificity 96%). We also evaluated the Eurofever/PRINTO classification criteria using our cohort and found a sensitivity of 94% and specificity of 91%. Conclusion: Using pediatric criteria for the diagnosis of FMF in children is a feasible and simple approach that can diagnose the disease based on at least two criteria. Therefore, our study supports the use of pediatric criteria in FMF diagnosis of children. Our results also confirm that the Eurofever/PRINTO classification criteria can be successfully applied for the diagnosis of FMF due to their high sensitivity (94%) and specificity (91%). What is Known: center dot The FMF diagnosis is made according clinical findings and supported by genetic analysis. center dot The use of adult diagnostic criteria in pediatric FMF patients is controversial since classical clinical presentation is often absent in children. What is New: center dot Our study supports both the use of pediatric criteria and Eurofever/PRINTO classification criteria in clinical practice.

    The Influence of Sex on Brain Development Genetics and the Possible Relationship with Sex-Dependent Differences in Psychiatric Disorders
    (2021) Bagcaz, Arda; Terzi, Yunus Kasim; Sahin, Feride Iffet; 0000-0001-5947-0179; 0000-0001-7308-9673; AAK-2321-2021; AAC-7232-2020
    There are sex-dependent differences in the prevalence, age of onset, and course of psychiatric disorders and cognitive abilities. Although it has been assumed that the direct effect of gonadal hormones in sensitive periods leads to sexually dimorphic brain development, current evidence suggests that another possible factor may be sex-specific regulations at the gene level. Understanding the sex differences at the gene level can be promising to identify the mechanisms that predispose or trigger psychiatric disorders, and may provide new prevention or treatment strategies. This paper aims to review the findings on the mechanisms that affect the sex-specific differences in brain development at the gene level and to discuss the relationship of these findings with different cognitive characteristics of the sexes and psychiatric disorders.

    (2020) Inan, Serhat; Babakurban, Seda Turkoglu; Erbek, Selim Sermed; Terzi, Yunus Kasim; Sahin, Feride Iffet; 0000-0001-7308-9673; 0000-0001-5067-4044; 0000-0003-4825-3499; 0000-0001-5612-9696; 0000-0001-8821-4481; AAC-7232-2020; AAI-8856-2021; AAJ-1407-2021; B-7604-2019; B-4372-2018
    Background: Adenoid hypertrophy (AH) is one of the possible causes of chronic inflammation in the middle ear. It has been suggested that CX3CL1 and its specific receptor (CX3CR1) could be related with the pathogenesis of some inflammatory diseases. The aim of the present study was to evaluate the role of CX3CL1 and CX3CR1 in the pathogenesis of AH with chronic otitis media with effusion (COME) in children. Materials and methods: Adenoid tissue samples were obtained from 91 pediatric patients and divided into two groups: adenoidectomy only for AH (n: 47) and adenoidectomy in conjunction with ventilation tube insertion for AH + COME (n: 44). Expression levels of CX3CL1 and CX3CR1 genes were compared. Results: Expression levels of CX3CL1 and CX3CR1 in hypertrophic adenoid tissue were not significantly different between the AH + COME and All only groups. Although no significant difference was detected in the expression of CX3CL1 in the adenoid samples, the expression of CX3CR1 was higher in children older than 48 months. Conclusions: When allergy, atopy and chronic adenoiditis does not exist to obstructive adenoid hypertrophy, inflammatory fractalkine chemokine expression levels in adenoid tissue was not observed to be increased in children with COME.

    (2020) Eroglu, Fatma Corak; Oto, Sibel; Sahin, Feride Iffet; Terzi, Yunus; Kaya, Ozge Ozer; Tekindal, Mustafa Agah; 0000-0003-0171-4200; 0000-0001-7308-9673; 0000-0001-5612-9696; 32631000; AAJ-4668-2021; AAC-7232-2020; B-4372-2018
    Objectives: To investigate the prevalence of strabismus in families of a proband with accommodative, partial accommodative, or infantile esotropia, and to evaluate the mode of inheritance and the role of consanguineous marriages in this prevalence. Materials and Methods: Families of probands with comitant strabismus were invited to participate in the study. The family members of 139 subjects with accommodative, 55 with partial accommodative, and 21 with infantile esotropia agreed to participate. Detailed family trees were constructed. The first- and second-degree relatives were invited for a complete ophthalmological examination, and 518 individuals from 168 families were evaluated. The role of consanguinity, the presence of tropia, phoria (>= 8 PD), microtropia, and hypermetropia (>= 3.00 D) among first- and second-degree relatives were analyzed. Results: A non-Mendelian pattern was found in 49 families (23%), an autosomal dominant pattern in 39 families (18%), and an autosomal recessive pattern in 6 families (3%). The prevalence of consanguineous marriages among parents of probands was 18.1%, 22.6%, and 14.3% in the accommodative, partial accommodative, and infantile esotropia groups, respectively (p=0.652). The prevalence of strabismus in first-degree relatives was 58.9%, 45.5%, and 38.1%, respectively (p=0.07). The prevalence of microtropia in probands' siblings was significantly higher in the accommodative esotropia group (p=0.034). Conclusion: Sporadic cases and non-Mendelian inheritance were more frequent than autosomal recessive inheritance. Autosomal recessive inheritance was found not to be frequent in consanguineous marriages. The prevalence of strabismus and microtropia was significantly higher in families of esotropia cases than in the general population.

    (2020) Yaman, Derya; Takmaz, Tamer; Dincer, Selin Akad; Sahin, Feride Iffet; 0000-0001-7308-9673; AAK-2511-2021; AAC-7232-2020
    Objective:To investigate the effect of single nucleotide polymorphism rs58073046 A>G within the ARHGEF12 gene in patients with hypercholesterolemia and primary open angle glaucoma. Methods: Blood samples of 20 patients with high serum cholesterol and primary open angle glaucoma (Group 1), 20 sex and age matched healthy subjects (Group 2) as controls were enrolled to the study. The ARHGEF12 gene polymorphism was determined by polymerase chain reaction and DNA sequence analysis. The data were assessed by descriptive statics and Fisher exact x(2) test. Results: The homozygous wild type genotype (AA) was identified in 95 % of Group 1 versus 100 % of Group 2. The homozygous mutant genotype (GG), presented the highest prevelance in Group 1 (5%), although the difference was not statistically significant between groups (p=0.5). Conclusion: This is the first study to identify the role of ARHGEF12 gene variant in the risk of hypercholesterolemia and POAG. Our results showed that there is no association between rs58073046 A>G polymorphism and disease development.

    Evaluation of silent information regulator T (SIRT) 1 and Forkhead Box O (FOXO) transcription factor 1 and 3a genes in glaucoma
    (2020) Yaman, Derya; Takmaz, Tamer; Yuksel, Nilay; Dincer, Selin Akad; Sahin, Feride Iffet; 0000-0001-7308-9673; 0000-0002-3808-7004; 33200312; AAK-2511-2021; AAC-7232-2020
    Analysis of the reactive oxygen species (ROS)-detoxifying biomarkers may elucidate the mitochondrial dysfunction in glaucoma pathogenesis. Therefore, we purposed to investigate the effects of ROS-detoxifying molecules including Silent Information Regulator T1 (SIRT1) and Forkhead Box O 1 (FOXO1) and 3a (FOXO3a) transcription factors in patients with glaucoma. Our analyses included 20 eyes from patients with primary open-angle glaucoma (POAG) and 20 eyes from patients with pseudoexfoliation glaucoma (PXG) who were scheduled for trabeculectomy. After extraction of total RNA from trabecular meshwork tissue, we compared the levels of SIRT1, FOXO1and FOXO3a genes in the oxidative pathway with the level of glyceraldehyde-3 phosphate dehydrogenase (GAPDH), the reference gene, using real-time polymerase chain reaction. Relative gene expression was calculated using the threshold cycle (2(-Delta Delta CT)) method. We observed similarly reduced expression levels of SIRT1, FOXO1, and FOXO3a genes versus GAPDH among patient groups (p = 0.40; p = 0.56; p = 0.35, respectively). This is the first study to identify the role of SIRT1 and FOXOs in human TM with glaucoma. Relative expression levels of SIRT1, FOXO1, and FOXO3a genes versus a control gene (GAPDH) were decreased in POAG and PXG groups. Our results show that SIRT1and FOXOs (1-3a) deserve special attention in the pathogenesis of glaucoma.
