Eosinophil level, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio as biomarkers of asthma exacerbation
(Mediton Publishing House, 2025) Şenel, Merve Yumrukuz; Karadoğan, Dilek; Kaya, İlknur; Telatar, Tahsin Gökhan; Akgün, Metin
Assessing asthma control and exacerbation risk in patients with asthma are so important to define. Our aim was to explore the relationship between the history of exacerbations in asthmatic patients and key inflammatory markers, namely eosinophil levels, the neutrophil-to-lymphocyte ratio (NLR), and the platelet-to-lymphocyte ratio (PLR). We also aimed to evaluate the potential of these biomarkers as indicators for asthma exacerbation. Patients with asthma were categorized into two groups based on their exacerbation history, with one group having at least one exacerbation in the last year (Group I) and the other group having none (Group II). The differences in eosinophil, NLR, and PLR values between the two groups were assessed. The mean age of the patients was 52±13 years, and 194 of the 252 asthmatic patients were female (77%). There were 79 (31.6%) patients in Group I and 173 (68.4%) patients in Group II. No statistically significant relationship was found between eosinophil count and asthma exacerbation (p=0.551). However, the NLR and PLR values were significantly higher in Group I (p=0.013 and p=0.002, respectively). In regression analysis, the PLR value was found to be a significant marker for predicting exacerbation. This study revealed higher PLR levels in patients experiencing asthma exacerbations and showed that this parameter significantly predicted exacerbations. Eosinophils and NLR values are not suitable biomarkers for predicting exacerbation risk but can be used to phenotype patients with asthma.
A case of kabuki make-up syndrome type-2 with autism spectrum disorder
(Galenos Publishing House, 2025) Naralan, Yüksel Sümeyra; Naralan, Muhammed Enes
Kabuki make-up syndrome, caused by mutations in the KDM6A gene on chromosome Xp11.23, is a rare genetic disorder characterized by distinct facial features such as outward-turned down lateral eyelids, curved and sparse eyebrows, long palpebral fissures, a flattened wide nose, wide ears, mental disability, skeletal anomalies, postnatal growth retardation, and dermatoglyphic anomalies. In this case of KMS type 2, a fourteen-year-old patient was referred to outpatient clinic by a paediatric neurologist. The patient presented with difficulties in forming relationships, mobility issues, and problems with anger management. Given the presence of dysmorphic facial features, an autism spectrum disorder (ASD) diagnosis, and mental retardation, clinician opted for next-generation genome sequencing, which revealed a de novo mutation in the KMDA6A gene located in the Xp11.3 chromosome region. Although KMS type 2 is a rare genetic syndrome, it is crucial for child psychiatrists to increase their awareness of this condition due to its clinical manifestations, which include ASD and cognitive development delays. This awareness can aid in facilitating early diagnosis and determining the special requirements for managing accompanying comorbid psychiatric conditions and designing tailored educational treatments during follow-up care.
Evaluation of natural radioactivity and radiological risks in baby powders
(Gumushane University, 2025) Dizman, Serdar; Camgöz, Kübra
All living things are constantly exposed to ionizing radiation emitted from natural and artificial radiation sources present in the world throughout their lives. Therefore, it is very important to determine the radioactivity levels of the products that people use and the environment they live in. In this context, 12 baby powder samples of different companies were obtained from local markets. The concentrations of226Ra,232Th and40K in the powder samples were measured using a high purity germanium detector (HPGe). It was determined that226Ra,232Th and40K radioisotope concentrations in the examined powder samples ranged between 2.31-12.71 Bq/kg, 1.26-13.68 Bq/kg and 4.69-38.21 Bq/kg, respectively. The average226Ra,232Th and40K radioactivity concentrations in the powder samples were 5.11 ± 0.81 Bq/kg, 4.17 ± 0.59 Bq/kg and 17.30 ± 1.59 Bq/kg, respectively. To assess the radiological hazards from natural radioisotopes in the examined powder samples, the annual effective dose values (YED) was calculated and compared with the average values recommended by reputable international organizations. As a result, it was determined that the use of the examined powder samples would not pose a radiological risk.
Effect of propolis extracts on OxLDL and LOX-1 Levels in ApoE knockout mice fed a high fat diet

Atherosclerosis, which has important effects on the development of cardiovascular diseases, is a widespread health problem with the highest mortality rate globally. In this study, we aimed to assess the impact of water and ethanolic extracts of propolis on oxidized low-density lipoprotein (OxLDL) and lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) in the progression of the atherosclerotic process, which is characterized by oxidative stress, inflammation, and dyslipidemia. In our study, apolipoprotein E knockout (ApoE−/−) and C57BL/6J mice were used as study groups. Water (WEP) and ethanolic extracts (EEP) of propolis were administered intraperitoneally to ApoE−/− and C57BL/6J mice modeled with a high-fat diet. Under anesthesia, the animals were euthanized by decapitation, and serum, along with aortic tissues, was collected. Serum total cholesterol (TC), triglyceride (TG), OxLDL and LOX-1 levels, OxLDL levels in aortic tissue homogenate, and subendothelial lipid accumulation levels by histological staining were determined in mice and statistical analyses were performed. WEP and EEP supplementation significantly decreased serum TC, TG, OxLDL, LOX-1, and tissue OxLDL levels and reduced plaque burden in the aortic root, with statistically significant differences observed. Those results suggest that propolis extracts have a potential treatment option for atherosclerosis, as a food supplement or a complementary medical/functional food. However, further research is needed to elucidate their molecular mechanisms, evaluate clinical efficacy and safety, and explore possible synergistic effects with existing atherosclerosis treatments.
Shoaling and sedimentation dynamics in fishery shelters: a case study of sandıktaş fishery shelter
(Multidisciplinary Digital Publishing Institute (MDPI), 2025) Süme, Veli; Yılmaz, Enver; Marangoz, Hasan Oğulcan; Daneshfaraz, Rasoul; Ebadzadeh, Parisa; Abraham, John Patrick
Sediment transportation on coasts can be significantly affected by rivers, wave–wind effects, and human activities. As a result, undesirable effects such as shoaling or erosion may occur in fishery shelters. This study examines the “Sandıktaş a Fishery Shelter”, a coastal structure in the Eastern Black Sea region of Turkey, and its susceptibility to shoaling. Bathymetric measurements were performed within the nearshore and onshore, and sediment samples were taken periodically from selected points and analyzed in the laboratory. The characteristic grain diameters of the sedimentation were obtained. It was revealed that the average grain diameter was d50 = 0.30–0.91, caused by an increase of 11,611 m3 in shoaling, which caused the decrease of 8 cm water depth that occurred between 2019 and 2022. The entrance of the fishery shelter has become progressively shallower, making it difficult for boats to navigate. Existing breakwater configurations played a role in trapping sediments, requiring optimized breakwater designs/modifications for improved sediment control. The Mann–Kendall test showed an increasing trend in sediment accumulation, particularly in coarser fractions. The findings highlight the necessity of periodic dredging and potential structural modifications to mitigate shoaling and ensure the long-term sustainability of the fishery shelter. Moreover, they emphasize the critical challenges caused by sedimentation in fishery shelters and provide data-driven recommendations for enhancing coastal engineering practices and maintenance strategies.
