Turkish version of a short nutrition literacy scale for young adults: cultural adaptation and validation.

Background: Recent changes in nutrition trends may lead to health issues. In particular, the unhealthy eating habits of young adults suggest that future generations may be at risk. Therefore, the importance and necessity of nutrition literacy is becoming increasingly apparent. Purpose: The purpose of this study was to create a Turkish version of a short nutrition literacy (S-NutLit-Tr) scale for young adults developed by Vrinten et al (2023). Methods: This research involved 115 young adults from Istanbul Gelisim University, who were selected through convenience sampling, a non-probability sampling method. After the original S-NutLit scale was translated into Turkish, the validity and reliability of the determined factor structure were tested on 115 young adults. Internal consistency was examined with the Cronbach Alpha coefficient. Confirmatory factor analysis was employed to validate the two sub-scale structures. Finally, measurement invariance was tested concerning participants' gender, aiming to ascertain whether the scale captured equivalent characteristics across different groups. Results: As a result of the reliability analysis conducted with the scale of S-NutLit-Tr, the Cronbach Alpha coefficient was obtained as 0.86 for the scale of S-NutLit-Tr. Additionally, it was found to be 0.84 and 0.77 for the "information skills" and "expert skills" sub-scales, respectively. Accordingly, the scale of S-NutLit-Tr was found to be reliable. To examine the two sub-scale factor structures of the S-NutLit-Tr scale, fit indices were examined: χ2/df (1.246), GFI (0.923), IFI (0.975), TLI (0.967), CFI (0.974), RMSEA (0.046), and SRMR (0.055) and it was observed that the indices were within acceptable limits. In the analysis results obtained through the multi-group confirmatory factor analysis for measurement invariance, it was observed that the ∆CFI and ∆TLI values across all indices were less than or equal to 0.01. Consequently, it was observed that the item-factor structure, factor loadings, variances, covariances, and error variances of the scale were equivalent for both male and female young adults. Conclusion: The study found that the scale of S-NutLit-Tr for young adults was a valid and reliable measurement tool in Turkish culture.

My sweetheart has a basketball match: The relationship between love-hate and identification of individuals attending a euroleague match for recreational purposes.

The objective of this research was to examine the Love-Hate and Identification Relationship of Individuals Participating in Euroleague Match for Recreational Purposes. The study was conducted using a relational survey methodology. The study's population comprises persons who watching recreational purpose part in the Euroleague match held in Istanbul in 2023-2024 season, while the sample consists of 178 voluntary participants selected through convenience sampling. The participants completed the Fan Love-Hate Scale and Fan Identification Scale, in addition to being asked about their gender, marital status, age, educational status, and frequency of attending football matches per week. The data collected from the personal information form and scales was entered into the IBM SPSS 24.0 software package for analysis. Statistical analyses were conducted using the Independent Sample T test and One-way Anova methods. The LSD test was employed to ascertain the dissimilarity between the groups. The Pearson correlation analysis was utilized to ascertain the association between the variables of love-hate and identity. In summary, it is evident that demographic factors, including gender and age, significantly influence fan perceptions and sports identification. In contrast, there is no substantial correlation observed between attributes such as level of education achieved and the frequency of engaging in sports activities, and the aforementioned outcomes. The significant associations identified between the Fan Love-Hate Scale and the Sports Fan Identification Scale underscore the complex relationship between fans' emotional experiences and their connection to sports. Further investigations could be conducted to go deeper into the underlying causes that contribute to these relationships and inequalities, so resulting in a more thorough understanding of fan psychology.

The Turkish Version of a Personal Responsibility Scale for Chinese College Students: Adaptation and Validation.

Purpose: The purpose of this study is to carry out the Turkish adaptation study of the personal responsibility scale developed by Ren et al for Chinese university students and to examine the validity and reliability of the adapted scale. The original scale was developed to determine the personal responsibility levels of Chinese university students. This research is very important in terms of determining the personal responsibility levels of Turkish university students. Methods: This research involved university students, who were selected through purposeful sampling, a non-probability sampling method. After the original scale was translated into Turkish, a pilot study was conducted on 165 students and exploratory factor analysis was conducted to reveal the scale structure. The validity and reliability of the determined factor structure was tested on 259 students. Internal consistency was obtained with the Cronbach Alpha coefficient. Confirmatory factor analysis was used to check the validity of the two subscale structure. Results: To examine the two-dimensional factor structure of the scale, fit indices were examined: X2/df (1.591), GFI (0.949), IFI (0.937), TLI (0.920), CFI (0.936), RMSEA (0.048) and SRMR (0.050) and It was observed that the indices were within acceptable limits. In the analysis results conducted with the multi-group confirmatory factor analysis method for measurement invariance, it was observed that ∆CFI and ∆TLI values among all metrics were less than or equal to 0.010. Conclusion: The Turkish version of the personal responsibility scale for Chinese college students, consisting of 12 items and two subscales, was proven to be a confirmatory and reliable tool to measure university students' awareness of personal responsibility.

Adaptation and Validation of the Post-Pandemic Health Promotion Behavior of Young Adults in the Digital Age (PS-SGD) Scale in the Turkish Population.

BACKGROUND: Young adulthood is a critical developmental period in which individuals establish life-long health behaviors and take responsibility for their own health care. Health promotion strategies tailored to young adults, leveraging digital tools, and addressing challenges exacerbated by events like the COVID-19 pandemic are needed. The aim of this study was to adapt the post-pandemic health promotion behavior of young adults in the digital age (PS-SGD) scale to the Turkish population in order to assess and compare the health behavior of young adults after the pandemic. METHODS: A total of 312 participants, aged between 19 and 29 years, were included in the study via non-probabilistic criterion sampling, while the Turkish adaptation process started with translation and back translation methods performed with three language and two health science experts. For statistical analysis, EFA and CFA were conducted to evaluate internal consistency and structural validity. Confirmatory factor analysis was utilized to confirm the structure of the six sub-dimensions. Additionally, measurement invariance was examined regarding participants' gender to determine if the scale accurately captured similar traits across diverse groups. The relationship between the test-retest data was tested by Pearson correlation to measure consistency and its invariance over time. RESULTS: The gender distribution of the sample was found to be 61.3% female and 38.7% male. According to the results of EFA, items 8 and 18 were removed from the Turkish-adapted version. As a result of the reliability analysis conducted with the Turkish version of the scale, the Cronbach alpha coefficient was obtained as 0.851 for the post-pandemic health promotion behavior. Additionally, the scale was rated as reliable with the following Cronbach alpha values: 0.79 for the "personal hygiene", 0.78 for "dietary habits", 0.72 for "using mobile devices", 0.70 for "emotional health", 0.68 for "health care and physical activity", and 0.51 for "social health" sub-dimensions. To examine the six sub-dimension factor structures of the scale, fit indices were calculated as χ2/df (1.722), GFI (0.894), IFI (0.908), TLI (0.892), CFI (0.907), RMSEA (0.048), and SRMR (0.057) and were within acceptable limits. Findings of the multi-group confirmatory factor analysis for measurement invariance were less than or equal to 0.01 for the ∆CFI and ∆RMSEA values across all indices. Consequently, it was observed that the item-factor structure, factor loadings, variances, covariances, and error variances of the scale were equivalent for both male and female young adults, while test-retest results showed a high positive correlation. CONCLUSIONS: The Turkish version of the post-pandemic health promotion behavior scale of young adults in the digital age scale, consisting of 25 items and six subscales, was proven to be a valid and reliable tool to measure health promotion behavior in young adults aged 19-29 years.

Prevalence and risk factors of food insecurity among Syrian refugees in Türkiye.

BACKGROUND: Although Türkiye (Turkey) hosts the largest number of Syrian refugees, studies on food insecurity are limited. This study examined the prevalence and risk factors of food insecurity among Syrian refugees living in Istanbul, which has the highest number of refugees in Türkiye. METHODS: A cross-sectional survey was conducted among Syrian refugees in Istanbul between September 2021 and March 2022. The main income earners of 103 households were interviewed by a research dietitian, with the assistance of an Arabic speaking interpreter through hour-long face-to-face. Data on sociodemographic characteristics (age, gender, nationality, marital status, educational status, the family income, the major source of family income, and the number of family members living in the household etc.) and household food insecurity status were collected. Household food insecurity status was assessed with the eighteen-item Household Food Security Survey Module. RESULTS: The household food insecurity rate was 90.3%, and those of adults and children were 88.4% and 84.8%, respectively. It was observed that family income level was significantly associated with food insecurity. A one-unit increase in monthly income increased food security by 0.02 times (p < 0.001). The number of employed refugees in the food security group was higher than that in the food insecurity group (p = 0.018). A significant difference was found in the rate of occupation type of the major income earner between the groups (p = 0.046). CONCLUSIONS: High rates of food insecurity, particularly severe food insecurity, were found among Syrian refugees living in Istanbul. While more research is warranted to explore the root causes and efficacy of the current support system, it requires the immediate attention of policymakers at the national and international levels to implement effective policies and interventions.

Pituitary volumes in patients with adjustment disorder.

The pituitary gland plays an important role in the stress response mechanism. Given the direct link between adjustment disorder and stress, we hypothesized that there might be changes in the pituitary gland in these patients. The study comprised a patient group of 19 individuals with adjustment disorder according to the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition, and 18 healthy controls. The mean pituitary gland volumes of the patient group were not statistically significantly different from those of the healthy control group (80.81 ± 1.82 mm3 in patients with adjustment disorder vs. 81.10 ± 7.04 mm3 in healthy controls, with a statistically nonsignificant difference of P > 0.05). This finding is contrary to our previous findings in anxiety-related disorders. In this regard, adjustment disorder is not similar to anxiety-related disorders in terms of pituitary gland volumes. We should also clearly state that our study is a pioneering study and that studies with large samples are needed to support our findings. The limitations of our study can be attributed to the small sample size, the utilization of a cross-sectional design, and the inclusion of patients using psychotropic drugs.

The knockdown of stathmin with si-RNA inhibits invasion of mesothelioma.

BACKGROUND: To investigate the mechanism of action of stathmin1 (STMN1) in mesothelioma (MSM) and whether it has any role in its treatment. METHODS: STMN1 expression was examined using immunohistochemistry in biopsy tissues taken from MSM patients. The relationships between the levels of STMN1 expression in the pathology preparations of MSM patients, and the clinicopathological characteristics of these patients, and their survival times were investigated. Transfection of STMN1-specific siRNA into SPC212 cells was compared to negative control siRNAs. The mRNA levels of genes that may play a role in invasion, apoptosis, and autophagy were evaluated by RT-PCR. RESULTS: The expression of STMN1 was shown to be high in MSM tissues (p < 0.05). It was found that the only independent predictor factor affecting the survival time of MSM patients was the disease stage (p < 0.05). STMN1 was significantly reduced after siRNA intervention (81.5%). STMN1 with specific siRNA has been shown to suppress invasion by reducing the mRNA levels of cadherin-6 (CDH6), fibroblast growth factor-8 (FGF8), hypoxia-inducible factor 1 (HIF1A), matrix metallopeptidase 1-2 (gelatinase A) (MMP1-2), and TIMP metallopeptidase inhibitor 2 (TIMP2), which are important markers for invasion. Although the expression of apoptosis and autophagy-related genes, caspase-2 (Casp2) and LC-3, was reduced by silencing STMN1 with specific siRNA in western blot analysis, this effect was not observed in PCR results. CONCLUSIONS: Immunohistochemical analysis of STMN1 may contribute to the differential diagnosis of MSM, and STMN1 may also be considered as a potential therapeutic target in the early invasive stage of MSM therapy.

The association of the quality of life with Afghan households' food insecurity before and after the recent political change in Afghanistan: a comparative analysis.

The overreaching objective of the current study is to investigate the association of quality of life with Afghan households' food insecurity. The data was collected immediately after the Taliban took control of a large part of Afghanistan. About a total of 555 households' heads participated in a face-to-face interview, using the HFIAS and WHOQOL-100 questionnaires along with some questions related to their socioeconomic characteristics at two different times, before and after the Taliban's takeover. The comparative analysis showed that 98% of Afghan households were food insecure after the Taliban takeover, while 70% of them faced food insecurity before the Taliban's takeover. The quality of life in the Taliban era is worse than before the Taliban. All dimensions of quality of life have decreased, and this decrease was more pronounced for the psychological, environmental, and physical domains. It is recommended that international organizations, NGOs, and local agents focus on these dimensions of the quality of life to improve food security.

High-throughput screening and clinical importance of autophagy-associated genes in basal cell carcinoma.

Autophagy is a type II programmed cell death mechanism that plays a critical role in preserving cellular homeostasis through the regulation of protein, lipid, and organelle quality control. It has become gradually evident that autophagy plays a fundamental role in the initiation and progression of various types of human cancers. Nevertheless, its significance in non-melanoma skin cancers, particularly in basal cell carcinoma, has not been well documented and remains largely elusive. In this study, we aimed to illuminate the role of autophagy-associated signaling signatures during development and progression of basal cell carcinoma. For the study, a total of 72 autophagy-related genes were screened using a high-throughput qPCR approach integrating Fluidigm 96.96 Dynamic Array™ integrated fluidic circuits (IFC) and BioMark™ HD Real-Time PCR system, which enabled efficient and precise analysis of gene expression patterns. Results were analyzed using Fluidigm's Real-Time PCR Analysis software and 2-ΔΔCt formula was used for the calculation of expression changes. Notably, expression levels of INS, TMEM74 and IFNA2 genes were identified to be prominently altered in BCC comparted to adjacent healthy tissues. However, only IFNA2 expression showed statistically significant change in BCC. Consequently, these findings suggest that IFNA2 might play significant role in the regulation of autophagy in BCC development and progression and can be therapeutically targeted.

Could Corneal Densitometry be a Progression Criterion for Subclinical Keratoconus?

Objectives: The objective of this study is to investigate the changes in topometry, tomography, and corneal densitometry in subclinical keratoconus (SK) at the 6-month interval. Methods: The clinical keratoconus and SK groups included 25 eyes; the control group included 22 eyes from 22 patients. Corneal topographic, tomographic, topometric, and densitometric values obtained using the Pentacam HR imaging system were analyzed. Results: Posterior elevation (PE), Keratoconus index (KI), index of height asymmetry (IHA), index of height decentration (IHD), Dp, Da, Final D, maximum pachymetric progression index (PPImax), and maximum Ambrósio relational thickness parameters showed significant changes between the baseline and the 6th-month follow-up in SK group (p<0.05 for all values). There were significant changes in all zones except a central layer of 6-10 zone, anterior, and central layer of 10-12 zone between the baseline and the 6th-month follow-up in the SK group (p<0.05, for all values). The changes in mean±standard deviation of KI, IHA, IHD, PPImax parameters, and corneal densitometry values of the posterior layer of 0-2 mm and 2-6 mm zones were significant in the SK group compared to the controls (p<0.05, for all values). Conclusion: PE, KI, IHA, IHD, and PPImax parameters as well as increasing corneal light backscatter of the posterior central layer might be useful for follow-up of progression of SK. New multimeric parameters created by combinations of topometric, tomographic, and corneal densitometry parameters could be the future of SK follow-up.

Factors associated with Afghan household food security pre- and post-Taliban regime.

To determine multifaceted determinants of household vulnerability to food insecurity in Afghanistan before and after the Taliban takeover, we randomly selected 555 households from 13 provinces, conducted in-person surveys, and applied the Household Food Insecurity Assess Scale (HFIAS) and Structural Equation Modeling (SEM). We collected data from January to April 2022. We observed an increase in both prevalence and severity of food insecurity among Afghan households after the Taliban takeover. Approximately, 98% and 70% of interviewed households were food insecure after and before the Taliban takeover, respectively. Similarly, households were more likely to be severely food insecure (81%) than before (40%). Our results showed that policy and political conditions contributed substantially to the food insecurity of Afghan households after the Taliban takeover. We recommend that the Taliban forces facilitate the presence of humanitarian organizations and NGOs to improve low-income households' food security, especially for women and children. We also recommend that international organizations enhance their attempts to negotiate with the Taliban to ensure freedom for women.

Fibulin1 and mesothelin expressions in pancreas ductal adenocarcinoma.

OBJECTIVE: The balance between malignant tumor cells and the connective tissue surrounding them determines the aggressiveness of the tumor. We aimed to understand the effects of mesothelin (MSLN) and fibulin1 (FBLN1) expressions on survival in pancreas ductal adenocarcinoma (PDCA), and also whether these proteins have prognostic value for PDCA. METHODS: Of 80 patients in total, 40 who underwent the Whipple procedure for diagnosed PDCA between 2009 and 2016, and 40 patients with diagnosed pancreatitis as the control group, were included in the present study. Immunohistochemically, MSLN, and FBLN1 expressions were evaluated retrospectively. We assessed the relationship between the degree of MSLN, FBLN1 expression, clinical-pathological features, and survival rates in PDCA cases. RESULTS: The median follow-up duration was 11.4 (3-41) months. All of the patients for MSLN and FBLN1 were immune reactive. We detected a significant difference in MSLN expression between patients with PDCA and control groups, but not in FBLN1 expression. MSLN, FBLN1 expressions were categorized as lower-higher (L/H) groupings. There was no difference in the median overall survival (OS) of patients in the MSLN groups. The L-FBLN1 group had a median OS of 18 months (95% CI: 9.51-26.48) versus 14 months (95% CI: 13.021-14.97) in the H-FBLN1 group (interconnective tissue) (p=0.035). According to Kaplan-Meier analysis, L-FBLN1 expression in the tumor microenvironment was associated with longer survival in PDCA. The FBLN1 expression in the tumor microenvironment was shown to be significantly inversely related to OS (p=0.05). CONCLUSION: The FBLN1 expression, which is in the tumor microenvironment of PDCA, may serve as a prognostic biomarker.

Cortical Thickness of the Orbitofrontal Cortex in Patients with Alcohol Use Disorder.

AIMS: In the present study, it was hypothesised that compared to healthy control subjects, significant differences in the cortical thickness of the orbitofrontal cortex (OFC) region of the brain, which is relevant to both impulsivity and decision making, would be identified. METHODS: The subject groups included in the study were composed of 15 individuals who met the criteria for alcohol use disorder, according to the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM 5) diagnostic criteria based on the Structured Clinical Interview for DSM 5 (SCID), and were admitted to the Firat University School of Medicine Department of Psychiatry or were hospitalised, and 17 healthy control comparisons were made. The volumes of and cortical thickness of the OFC were measured in the subjects. RESULTS: It was found that patients with alcohol use disorder had reduced volumes of the OFC bilaterally and a thinner cortical thickness of the same region bilaterally compared to those of the healthy control comparisons. CONCLUSIONS: Consequently, it is suggested that the OFC region of the brain appears to be statistically significantly smaller in patients with alcohol use disorder, both in terms of cortical thickness and volume, compared to healthy controls. Future research should focus on the status of these relationships longitudinally and should assess the causality of the association with the treatment response.

Automated Adrenal Gland Disease Classes Using Patch-Based Center Symmetric Local Binary Pattern Technique with CT Images.

Incidental adrenal masses are seen in 5% of abdominal computed tomography (CT) examinations. Accurate discrimination of the possible differential diagnoses has important therapeutic and prognostic significance. A new handcrafted machine learning method has been developed for the automated and accurate classification of adrenal gland CT images. A new dataset comprising 759 adrenal gland CT image slices from 96 subjects were analyzed. Experts had labeled the collected images into four classes: normal, pheochromocytoma, lipid-poor adenoma, and metastasis. The images were preprocessed, resized, and the image features were extracted using the center symmetric local binary pattern (CS-LBP) method. CT images were next divided into 16 × 16 fixed-size patches, and further feature extraction using CS-LBP was performed on these patches. Next, extracted features were selected using neighborhood component analysis (NCA) to obtain the most meaningful ones for downstream classification. Finally, the selected features were classified using k-nearest neighbor (kNN), support vector machine (SVM), and neural network (NN) classifiers to obtain the optimum performing model. Our proposed method obtained an accuracy of 99.87%, 99.21%, and 98.81% with kNN, SVM, and NN classifiers, respectively. Hence, the kNN classifier yielded the highest classification results with no pathological image misclassified as normal. Our developed fixed patch CS-LBP-based automatic classification of adrenal gland pathologies on CT images is highly accurate and has low time complexity [Formula: see text]. It has the potential to be used for screening of adrenal gland disease classes with CT images.

Pituitary Volumes Are Reduced in Patients With Alcohol Use Disorder.

AIMS: To determine whether there is a difference in pituitary gland volumes in patients with alcohol use disorder compared to healthy people. METHODS: The subjects included in the study consisted of 15 individuals who met the criteria for alcohol use disorder according to the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM 5) diagnostic criteria based on the Structured Clinical Interview for DSM 5 and were admitted to Firat University School of Medicine, Department of Psychiatry, or were hospitalized, and 17 healthy controls. The volumes of pituitary were measured in subjects. RESULTS: Absolute pituitary gland volumes of patients with alcohol use disorder and healthy controls were compared in the analysis performed using the independent samples t-test. The mean volume of the patient group was significantly smaller than the healthy controls (58.02 ± 7.24 mm3 in patients with alcohol use disorder vs. 83.08 ± 12.11 mm3, P < 0.01), a difference which persisted after controlling for age, gender and total brain size. CONCLUSIONS: Patients with alcohol use disorder in this study had smaller pituitary gland volumes compared to those of healthy control subjects. However, this study has limitations including small sample size and not adjusting for previous or current medication use or current anxiety and depression.

Long-term evaluation of posterior corneal surface parameters after accelerated corneal cross-linking with a comparison with uncross-linked keratoconic eyes.

PURPOSE: To evaluate the 36 months changes in posterior corneal surface parameters in keratoconic eyes after accelerated corneal cross-linking and to compare the data with uncross-linked progressive and non-progressive keratoconic eyes. METHODS: Thirty five cross-linked, 30 uncross-linked progressive, and 30 uncross-linked non-progressive keratoconic eyes were included. Maximum keratometry (Kmax), thinnest pachymetry, minimum radius of curvature back (Rminback), asphericity back, posterior elevation and corneal densitometry, back corneal higher order aberrations (HOAs), back surface deviation (Db), final D, posterior radius of curvature (PRC) and 'B' unit values were recorded at baseline and at the 12, 24, 36 months follow-up. Data were analyzed with repeated measures ANOVA and paired t-tests. RESULTS: Kmax and thinnest pachymetry were significantly changed in the cross-linked and progressive uncross-linked groups. Rminback, asphericity back, and HOAs did not change in either group. Total posterior corneal densitometry improved; posterior elevation, Db and B unit worsened in the cross-linked group and did not change in the uncross-linked groups. PRC and final D worsened in the cross-linked and progressive uncross-linked groups, and did not change in the non-progressive group. CONCLUSION: Despite a decreased Kmax, the posterior corneal surface parameters, posterior elevation values were determined to have significantly worsened in the cross-linked group and this increase was higher than in progressive uncross-linked eyes.

Extrapulmonary tuberculosis: an old but resurgent problem.

Tuberculosis (TB) primarily affects the lungs, but some of its most devastating clinical consequences arise because of its ability to spread from the lungs to other organs. Extrapulmonary TB (EPTB) constitutes 15-20% of all TB cases. Imaging findings are not always specific and can mimic many diseases; therefore, EPTB should be considered in the differential diagnosis, particularly in patients with immune system disorders (AIDS, patients receiving chemotherapy, etc.) and those in other high-risk groups including people with diabetes. The bacterium's passage to the regional lymph nodes is essential for developing a protective T-cell-mediated immune response, but the bacterium can spread hematologically and via the lymphatic system, leading to extrapulmonary involvement. Diagnosis of EPTB in high-risk patients is made based on suspected clinical and radiological findings, but further positive culture and histopathological confirmation may be required in some instances. Radiological evaluations are critical for diagnosis and crucial in planning the treatment and follow-up. This paper aims to review the typical and atypical imaging features and the differential diagnosis of EPTB.

siRNA-mediated stathmin1 silencing inhibits proliferation of prostate carcinoma cell line.

Stathmin1 (STMN1) has been proposed as a possible prognostic marker and a potential therapeutic target for some cancers. We aimed to analyze the changes in autophagy, invasion, apoptosis-related genes in prostate cancer (PCa) cell line (PC-3), after small interfering RNA (siRNA)-mediated STMN1 silencing, and also the relationships of STMN1 expression, clinicopathological parameters, and survival (OS) in PCa cases. The STMN1 expressions were analyzed, immunohistochemically, in formalin-fixed paraffin-embedded 75 PCa and 15 benign prostatic hypertrophy (BPH) tissues. The correlation between the levels of expression STMN1, clinicopathological features, and OS was determined in PCa cases. The siRNA-mediated STMN1 incubated PC-3 cells were transfected and compared to negative control siRNAs. We determined mRNA levels in autophagy, invasion, and apoptosis genes with the combination of reverse transcription-polymerase chain reaction (RT-PCR) and western blotting in PC3 cell lines after STMN1 silencing. It was determined that STMN1 was overexpressed significantly in PCa cases, immunohistochemically. The overexpression of STMN1 was significantly correlated with the high-grade Gleason score, and it was associated with a worse prognosis of PCa cases according to the Kaplan-Meier survival analysis (p < 0.05). Significant silencing in STMN1 was determined (87.5%) after siRNA applications. Especially, invasion genes such as claudin 7, fibroblast growth factor 8, hypoxia-inducible factor 1 subunit alpha, hepatocyte growth factor, matrix metallopeptidase 2, 7 genes, markedly, decreased by siRNA-mediated STMN1silencing. STMN1 silencing was determined to significantly increase caspase 3 protein expression by using western blot analysis (p < 0.001). Although STMN1 silencing did not have a significant effect on the induction of apoptosis and autophagy-related genes in PCa cells, it was shown to affect apoptotic mechanisms through the caps3 protein. siRNA-mediated STMN1 silencing decreases proliferation in the PCa cell line. It is thought that STMN1 can serve as a potential therapeutic target in the advanced stage-PCa, especially.

Pituitary Volume in Individuals with Social Anxiety Disorder.

Background: There are no volumetric magnetic resonance imaging studies on the pituitary gland in individuals with social anxiety disorder. The present study aimed to investigate pituitary volume in individuals with social anxiety disorder compared to healthy controls due to the correlation between pituitary gland volume and stress response and the hypothalamic-pituitary-adrenal axis and hypothesized that pituitary gland volume would be different in these individuals. Methods: In this study, 21 individuals with social anxiety disorder based on fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) and 20 healthy controls were included. Both patient and control groups were scanned with a 1.5-Tesla General Electric (GE) Magnetic Resonance Imaging scanner. Pituitary volume was measured with the manual tracing method. Results: The statistical analysis revealed that the mean pituitary gland volume of the individuals with social anxiety disorder was significantly smaller when compared to that of healthy controls, statistically, as presented inTable 1 [594.10±104.56 mm3 for individuals with social anxiety disorder and 818.01±215.25 mm3 for healthy controls] when it was done by using the analysis of covariance controlled for age (F = 12.979, df = 1, P < .001), sex (F = 11.448, df = 1, P < .001), and total brain volume (F = 10.772, df = 1, P < .001), demonstrating that smaller pituitary volume in social anxiety disorder, when compared to healthy subjects, was an important finding independent of age, sex, or total brain volume. Conclusion: We suggest that social anxiety disorder may be associated with smaller pituitary volume, supporting the notion that anxiety itself could reduce the pituitary volume.

Superior Temporal Gyrus Volumes in Patients With Social Anxiety Disorder.

Objective: To determine if superior temporal gyrus volumes are altered in patients with a social anxiety disorder.Methods: Magnetic resonance imaging (MRI) was utilized to determine the superior temporal gyrus volume in 21 patients with a social anxiety disorder and 20 control subjects without a social anxiety disorder. The superior temporal gyrus volumes were measured by manual tracing method. The study was conducted between September 2019 and April 2020.Results: The mean superior temporal gyrus volume for both sides was statistically significantly smaller than that of control subjects (left side: 11.38 ± 0.85 cm3 for patients and 12.73 ± 0.86 cm3 for controls, t=-5.064, P < .001; right side: 11.42 ± 0.84 mm3 for patients and 12.92 ± 0.85 cm3 for controls, t=-5.574, P < .001). Moreover, when comparing volumetric measurements for subregions, we detected that volumes of all subregions were also statistically significantly smaller than those of healthy comparisons (for both sides of the Heschl's gyrus and planum temporale).Conclusions: The study findings suggest that patients with social anxiety disorder seem to have smaller superior temporal gyrus volumes compared to healthy control subjects, although we do not know whether these results were in accordance with functional changes of the same region.
