Accelerated Alkali-Silica Reaction After a Seven-Year Asr-Dormancy Period
(Kare Publishing, 2024) Beglarigale, Ahsanollah
The ongoing alkali-silica reaction (ASR) in concrete can be halted by dryness, which is im- portant for repairing ASR-suffered concrete structures. Drying of the concrete establishes an ASR-dormancy period until the end of the dryness. The residual expansion of such concrete after the ingress of water—the end of the dormancy period—is a significant risk, especially for repair works. In this experimental study, the post-dormancy expansion of various mixtures prepared by eight different Portland cement and three different supplementary cementitious materials (SCM) were tested using an accelerated mortar bar test. After accelerated ASR ex- pansions, an ASR-dormancy period was established by keeping the specimens dry for seven years; the residual ASR expansions of the specimens were tested by the same accelerated meth- od. The effect of pre-dormancy reactions on the residual expansions was discussed through two perspectives. The post-dormancy expansion behavior of mixtures without or with insuffi- cient SCM indicated that expansions were primarily driven by the swelling of old gel, whereas in specimens with sufficient SCM, the dominant mechanism was new gel formation, a result of lower pre-dormancy expansions due to the ASR-mitigating effect of SCMs.
Accuracy of Procalcitonin in the Diagnosis of Bacteremia and Discrimination from Contamination
(Istanbul University Press, 2025) Hayirlioglu, N.; Kaya, A.D.; Selale, D.S.; Kurç, M.A.; Varol, G.
Objective: In this study, we aimed to evaluate the concordance of blood culture with procalcitonin (PCT) alone and together with C-reactive protein (CRP) in detecting bacteremia and the diagnostic performance of these biomarkers to differentiate contamination from true bacteremia. Materials and Methods: The medical records of 310 patients were analysed retrospectively. Advia Centaur XP immunoassay system and Au analysers were used to determine PCT and CRP levels, respectively. BacT/ Alert 3D60 hemoculture system was used to incubate blood specimens, and VITEK 2 compact was used to identify isolated strains. Results: The accuracy of PCT and CRP in detecting bacteremia were found to be 68.1% and 36.4%, respectively, and combining PCT and CRP had no added value. In analysis of receiver operating characteristic (ROC), the area under the ROC curve (AUROC) values of PCT and CRP were found to be 0.889 and 0.779 in discriminating the culture-negative group from the culture-positive group, and 0.645 and 0.502 in discriminating bacteremia from contamination, respectively. Conclusion: PCT is a reliable marker that can be used to detect bacteremia. However, its discriminative power was low in differentiating true bacteremia from contamination. Therefore, PCT levels alone should not be used to rule out blood culture contamination. © 2025 Elsevier B.V., All rights reserved.

(Turkey AsSoc Physiotherapists, 2025) Kilic, Sefa; Alpay, Kubra; Atici, Emine; Soyal, Mehmet; Inal-Gultekin, Guldal
Proproseptif duyudaki eksiklikler yaralanma riskini artırmakta ve sporcunun performansını olumsuz yönde etkilemektedir. Kadın basketbol oyuncularında anaerobik yorgunluğun ve toparlanma sürecinin propriosepsiyon üzerine etkisi üzerinde sınırlı sayıda çalışma bulunmaktadır. Bu amaçla adolesan kadın basketbol oyuncularında anaerobik yorgunluğun alt ekstremite propriosepsiyonu üzerine etkisini değerlendirilmiştir. Çalışmaya 12–16 yaş aralığında 30 lisanslı kadın basketbol oyuncusu dahil edildi. Katılımcıların demografik bilgilerine takiben, istirahat, yorgunluk ve toparlanma olmak üzere üç durumda kalp atım sayıları, 30° ve 60° aktif ve pasif diz eklemi pozisyon hissi ölçümleri yapıldı. Diz eklemi pozisyon hissi ölçümleri için dominant bacakları değerlendirmeye alındı. Anaerobik yorgunluk için bisiklet ergometresinde Wingate anaerobik test protokolü uygulandı ve hemen sonrasındaki yorgunluk durumu verileri alındı. Toparlanma sonrası verilerin alınması için katılımcılar 10 dakika istirahate alındılar. Katılımcıların elde edilen yorgunluk nabızları ortalama 171,6±4,2 atım/dakika olarak tespit edildi ve karvonen formülüne göre hesaplanan iş yoğunluğu %72,7±2,9 olarak belirlendi. Anaerobik yorgunluk sonrası 30° ve 60° diz fleksiyonu aktif eklem pozisyon hissinde istirahat değelerine göre anlamlı azalma saptandı (p>0,017). Yorgunluk sonrası 10 dakikalık toparlanma ile 30° ve 60° diz fleksiyonu aktif eklem pozisyon hissinde tekrar istirahat seviyelerine dönüş olduğu belirlendi. Diz fleksiyonu 30° ve 60° pasif eklem pozisyon hissinde anaerobik yorgunluk sonrası anlamlı farklılık tespit edilmedi. Sonuç olarak, adolesan kadın basketbolcularında anaerobik yorgunluğun diz propripsepsiyonunu azalttağı saptanmış ve çalışmanın literatürdeki benzer bulgularla örtüştüğü görülmüştür. Bunula birlikte, 10 dakika kadar kısa bir toparlanma süresi ile propriyoseptif duyarlılığın başlangıç seviyelerine geri döndüğü görülmüştür.

Antioxidant Activity, Chemical Composition, and Therapeutic Activity of Essential Oils From Certain Lamiaceae Species in Türkiye
(Marmara Univ., Fac. Pharmacy, 2025) Karatoprak, Gökçe Şeker; İlgün, Selen; Dumlupınar, Berrak; Bağdat, Reyhan Bahtiyarca; Sürücü, Canan Göksu; Gürbüz, Burçak
The study examined the antioxidant, antimicrobial, and potential anticancer properties of lavandin (Lavandula x intermedia 'Grosso'), oregano (Origanum vulgare 'Uluğ Bey'), and sage (Salvia officinalis 'Beyhekim') essential oils (EOs). Chemical analysis revealed that oregano is rich in carvacrol (81.23%), cymene (5.51%), and 18- cineole (2.13%). Sage contains notable quantities of α-thujone (17.47%), camphor (13.59%), and borneol (12.14%). Lavandin is predominantly composed of linalool (41.10%), linalyl acetate (16.66%), and camphor (10.01%). The antimicrobial tests demonstrated that lavandin EOs exhibited a high inhibition rate of 90.77% at 1000 μg/mL, which subsequently decreased with lower concentrations. The oregano essential oils demonstrated robust antimicrobial activity across all concentrations, with a 10.97% inhibition rate observed even at the lowest concentration. The sage EOs exhibited a rapid decline in antimicrobial activity, reaching 4.97% at the lowest concentration. Both the DPPH and ABTS assays demonstrated that the antioxidant capacity of the essential oils was concentration-dependent. The cytotoxicity values of oregano essential oil were 35.58 at 50 μg/mL, 32.39 at 25 μg/mL, and 30.92 at 12.5 μg/mL. Similar cytotoxicity results were observed for sage and lavandin essential oils. These findings indicate that plant essential oils exert a dose-dependent cytotoxic effect on cell growth, significantly inhibiting cells at high concentrations. The research indicates that essential oils derived from Lamiaceae plants exhibit robust antimicrobial effects against a range of pathogens, suggesting potential applications as alternative therapies for specific microbial infections, comparable to ciprofloxacin at certain concentrations.

(2021) Özateş, Serdar; Kabataş, Emrah Utku; Dilli, Dilek; Zenciroğlu, Ayşegül
Purpose: To assess the relation between serum lactate level and development and progression of retinopathy of prematurity (ROP). Material and Methods: This retrospective study included premature newborns that received intensive medical care. Serum lactate levels that were obtained with three-day intervals during the fi rst month after birth was noted. Patients with ROP were included in ROP group and patients without ROP were included in control group. Results: 71 patients were included in ROP group and 35 patients included in control group. Mean gestational age 27.8 ± 1.8 weeks in ROP group and 28.7 ± 3.2 weeks in control group (p=0.061). Mean birth weight was 1150.4 ± 251.7 and 1262.3 ± 323.9 grams in ROP and control groups respectively (p<0.078). Mean serum lactate level at the fi rst day after birth was 36.6 ± 22.3 mg/dl in ROP group and 24.9 ± 12.8 mg/dl in control group (p<0.001). Mean serum lactate level at the fi rst month after birth was 26.6 ± 7.9 mg/dl in ROP group and 18.1 ± 6.5 mg/dl in control group (p<0.001). No signifi cant relation was observed between lactate level at the fi rst day and month and ROP stage and plus disease (p>0.05). Mean serum lactate level equal or over 21.2 mg/dl at the fi rst month predicted the development of ROP with a 76% sensitivity and 74% specifi city (Area under the curve: 0.837, p<0.001). Conclusion: Higher serum lactate levels were found associated with ROP and serum lactate level could be used to predict the development of ROP.

The Association Between Monocyte/HDL-C Ratio and Heart Failure
(Marmara Univ., Fac. Pharmacy, 2025) Gungor, Baris; Aksoy, Nilay; Berk, Barkin; Çattık, Büşra Nur
The monocyte/HDL-cholesterol ratio (MHR) was shown to be a marker of inflammation. This study investigated the utilization of this ratio as a measure of severity for heart failure which is a condition associated with inflammation. The MHR was calculated for 323 ambulatory patients with chronic heart failure and compared to other variables associated with the severity of the condition. Additionally, the impact of MHR on the Seattle Heart Failure Model (SHFM) score was investigated. MHR correlated positively with C-reactive protein (r: 0.312, p<0.001) and neutrophil-to-lymphocyte ratio (r: 0.242, p<0.001), but not with platelet-to-lymphocyte ratio. In addition, a correlation was found between the SHFM score and MHR (r:-0.267, p<0.001). The SHFM score exhibited a significant result for proB- type natriuretic peptide (pro-BNP) (p<0.001), neutrophil (p<0.001), hematocrit (p=0.001), and serum creatinine (p=0.001) in the ordinal logistic regression analysis, but not for MHR. MHR showed a negative correlation with left ventricular ejection fraction (r: -0.151, p: 0.007), exhibited a positive association with pro-BNP (r: 0.184, p<0.001), and no correlation with New York Heart Association classes. There is a significant correlation between the MHR value and the factors associated with the severity of heart failure. The prognosis and management of this condition may be assessed by utilizing the MHR value in conjunction with existing biomarkers.
Awareness of child abuse and neglect among students
(Kare Publ, 2022) Uysal, Gulzade; Bozkurt, Gulcin; Duzkaya, Duygu Sonmez
Objectives: This descriptive study was conducted to determine the level of awareness of child abuse and neglect (CAN) among students at a private university in Istanbul, Turkey. Methods: The study sample comprised 1533 students from all faculties and colleges of the university selected using the stratified sampling method. A demographic information form and the Child Abuse and Neglect Awareness Scale (CANAS) were used to collect the study data. Results:The findings revealed that 30.5% of the students had received some instruction about CAN and 72.9% indicated that they wanted lectures on CAN to be added to the curriculum. The mean total score of the CANAS and the mean scores of the physical abuse, emotional abuse, and neglect subscales were statistically significantly higher among female students (p<0.05). The physical abuse and neglect subscale scores of students who had formal education on abuse were higher than those of students who had not (p<0.05). Conclusion:The female students and those who had received instruction about abuse had greater awareness of abuse and neglect. Broader coverage in the curriculum may increase the awareness of all students and help to enhance public understanding.

Can Rectal Indomethacin Be an Alternative Local Anesthetic Method to Intrauterine Lidocaine During Endometrial Biopsy? A Clinical Observational Prospective Study
(Turkiye Klinikleri, 2020) Demircan Karadag, Sinem; Karadag, Cihan; Senturk, Mehmet Baki; Turgut, Abdulkadir
Objective: Endometrial biopsy is a pain-related gynecological procedure. The aim of this study is to compare the efficacy of rectal indomethacin and intrauterine lidocaine on pain control during endometrial sampling. Material and Methods: This clinical observational prospective trial was conducted in 120 patients with the complaint of abnormal uterine bleeding who presented at Istanbul Medeniyet University Goztepe Training and Research Hospital, Obstetrics and Gynecology Department, between January 2017 and June 2017. Patients were divided into two groups. The rectal group had 64 patients, to whom indomethacin was given as a local anesthetic. The intrauterine group had 56 patients, for whom lidocaine was the local anesthetic used. Endometrial biopsy was performed by using a no. 4 Karman cannula. The primary goal of measurement was pain intensity assessed by a visual analog scale before, during, and 10 minutes after the procedure. Results: There were no statistically significant differences between the two groups in mean age, body mass index, weight and median levels of gravidity, parity and abortion. The median pain scores of the two groups during and 10 minutes after the procedure were similar (p>0.05). Conclusion: In this study, rectal indomethacin was shown to be equal to intrauterine anesthesia for reducing pain during the endometrial biopsy. Rectal indomethacin may be an alternative drug to relieve pain during gynecological procedures. Further researches with larger numbers of patients are needed to confirm our findings.
Cancer Rate in Pulmonary Embolism Diagnosed Cases: A Single-Center, Retrospective Study
(Turkish Geriatrics Soc., 2025) Doğan, Demet; Gökçe, Kağan
Introduction: The aim of this study was to evaluate the incidence of pulmonary embolism in relation to age, cancer, and other comorbidities; to assess clinical, laboratory, and radiological findings; and to examine the associated mortality rate. Materials and Method: Patients diagnosed with pulmonary embolism were included in this single-center retrospective study. The patients were divided into two age groups: < 60 and > 60 years. The incidence of pulmonary embolism; presence of deep vein thrombosis, cancer, surgical history; other comorbidities; mortality rate; prevalence of embolism; and C-reactive protein and D-dimer levels were evaluated according to age group and sex. Results: Of the 1,281 patients who underwent pulmonary computed tomography angiography for suspected pulmonary embolism, 235 were diagnosed with pulmonary embolism. Of these, 114 were female and 121 were male. The mean age was 62.3 ± 16.8 years. In the ≥60 age group, the proportion of females was significantly higher than that of males (p < 0.05). Cancer prevalence and C-reactive protein and D-dimer levels were also significantly higher in this group (p < 0.05). No statistically significant differences were observed between the age groups for the other evaluated parameters. Conclusion: The incidence of pulmonary embolism is higher in the elderly population, and the presence of additional conditions, particularly cancer, further increases the risk of pulmonary embolism. Careful monitoring of elderly patients for comorbidities, risk factors, and complications—such as pulmonary embolism—is crucial. Early diagnosis and timely treatment play vital roles in reducing mortality and significantly improving quality of life.
The classical adiabatic constancy of PVγ for an ideal gas, can be shown to be a quantum mechanical occurrence, which yields the particular value of the constant, in question
(2012) Yarman,T.; Kholmetskii,A.L.; Korfali,O.
In this paper we find a full connection between the long lasting macroscopic classical laws of gases and the quantum mechanical description of non-interacting particles confined in a box, thus constituting an ideal gas. In such a gas, the motion of each individual molecule can be considered to be independent of all other molecules, and the macroscopic parameters of an ideal gas, mainly, pressure P and temperature T, can be defined as simple average quantities based on individual motions of all molecules in consideration. It is shown that for an ideal gas enclosed in a macroscopic cubic box of volume V, an alphanumeric expression for the Constant appearing in the classical law of adiabatic expansion law, i.e. PV5/3 = Constant, can be derived based on quantum mechanics. Note that this constant has otherwise remained for centuries, as just an abstract quantity in the form of P1V 15/3=P2V25/3 = P 3V35/3 written for different thermodynamic states, delineated through an adiabatic transformation. No one even seems to have thought that it may eventually have a particular expression. Physical implications of the result we disclose are discussed. © 2012 TIBTD Printed in Turkey.
Clinical impact of depression and anxiety in patients with non-cystic fibrosis bronchiectasis
(Turkish Assoc Tuberculosis & Thorax, 2020) Bekir, Melahat; Kocakaya, Derya; Balcan, Baran; Olgun Yildizeli, Sehnaz; Eryuksel, Emel; Ceyhan, Berrin
Introduction: Bronchiectasis is a chronic suppurative disease characterized by abnormal bronchial dilatation. The nature of bronchiectasis may have negative impact on psychological status, however it is poorly studied in relation to clinical indices, particularly the severity of disease. Primary aim of this study is to detect depression and anxiety in patients with non-cystic fibrosis bronchiectasis and to evaluate its relationship with disease severity indexes. Materials and Methods: Ninety (male/female= 37/53; median age 45 years) stable non-cystic fibrosis bronchiectatic adult patients were enrolled into this study. Dyspnea scores, number of exacerbations and hospital admissions within the last year, body-mass index, pulmonary function tests, sputum cultures, bronchiectasis disease severity indexes (BSI and FACED) were assessed. Anxiety and depression were evaluated by using the Turkish version of the hospital anxiety and depression scale questionaire. Results: Anxiety was diagnosed in 30% of patients and depression was diagnosed in 41% of the participants. Female participants had significantly higher rates of depression (55% vs. 22%; p= 0.002). Exacerbation rates within the last year were higher among the subjects with anxiety, moreover, patients with depression had shorter duration of disease. 851 and FACED severity indexes increased with longer duration of disease (5.6 +/- 5.0 yrs in mild group vs. 10.1 +/- 9.2 yrs in moderate-to-severe group, p= 0.035 and 5.7 +/- 5.4 yrs in mild group vs. 12.1 +/- 9.7 yrs in moderate-to-severe group, p= 0.001, respectively), however, anxiety and depression were not related with BSI and FACED severity indexes. Conclusion: Patients with non-cystic fibrosis bronchiectasis have an increased risk for depression and anxiety. Duration of disease and higher exacerbation rate are related with psychological status and indexes increased with longer duration of disease. Lady detection and taking the necessary measures to improve the psychological state is necessary for the overall management of these patients.

(2018) Tuğba ŞAŞMAZ KURU; Volkan EYÜPOĞLU
In the present study, the humidity sensing properties of Co-Mg nanocomposite prepared by chemically coprecipitatedhave been investigated by impedance analysis. The correlation between the impedance patternsand relative humidity have shown remarkable results for further investigation. Whereas, the humiditymeasurement capability of the sensor was high at low frequencies. Also, we identified that this ability wascontinuously diminished at higher frequencies. So, the hysteresis value for successive adsorption anddesorption of the humidity on ferrite nanocomposite material was also determined as small and also thelong time measurement stability was excellent. The response and the recovery times for nanocompositematerials were identified as 60 s and 300 s respectively. Finally, a direct relationship between the activeelectron and transport mechanism of the humidity onto the nanocomposite has been identified as anadvanced investigation.
