Improve the energy efficiency of the fruit freeze-drying through the predictive analysis
(Institution of Chemical Engineers, 2025) Öztuna Taner, Öznur; Çolak, Andaç Batur
The considerable energy expenditure involved in the freeze-drying of foods justifies the development of innovative engineering techniques. Artificial intelligence will facilitate mass balance and energy efficiency in future food freeze-drying processes. This study assessed the energy and manufacturing efficiency of the freeze-drying facility through the application of artificial intelligence. Two distinct artificial neural network models were created utilizing real-time data from a factory located in an industrial zone that processed freeze-dried vegetables and kiwi fruit. Analyzing energy efficiency values and production was done using network models constructed from 20 experimental data sets. The Levenberg-Marquardt approach was employed to train neural networks with a multilayer perceptron architecture. The neural network models' prediction values were compared with the experimentally acquired data, and their performance was examined using several performance criteria. The evaluations carried out for 20 different scenarios revealed overall energy efficiency rates ranging from 25.8 % to 64.5 %. The considerable energy expenditure involved in the freeze-drying of foods justifies the development of innovative engineering techniques. Artificial intelligence will facilitate mass balance and energy efficiency in future food freeze-drying processes.
Comparison of the incidence of recovery agitation with two different doses of ketamine in procedural sedation: A randomized clinical trial
(John Wiley and Sons Inc, 2025) Türkücü, Çağrı; Parlak, İsmet; Kokulu, Kamil; Sert, Ekrem T.; Mutlu, Hüseyin
The objective was to compare the incidence of recovery agitation and efficacy of two different intravenous (IV) doses of ketamine (0.5 mg/kg vs. 1 mg/kg) in adult patients who presented to the emergency department (ED) requiring procedural sedation with ketamine. Methods: This randomized, prospective clinical trial included patients aged 18–75 years who required procedural sedation with ketamine in the ED. Patients were randomized to receive IV ketamine at either 0.5 mg/kg (low dose) or 1 mg/kg (high dose). The primary outcome was the incidence of recovery agitation, assessed by the Richmond Agitation–Sedation Scale (RASS) at 5, 15, and 30 min following the procedure, in both dosage groups. Secondary outcomes included overall efficacy, sedation duration, and changes in vital signs. Results: A total of 108 patients were enrolled in the study, 54 in each group. The median (IQR) RASS scores at 5, 15, and 30 min were −4 (−5 to −4), −1 (−1.3 to 0), and 0 (−1 to 0.5), respectively, in the low-dose group and −4 (−5 to −4), −1 (−3 to 0), and 0 (0 to 0), respectively, in the high-dose group. The incidence of recovery agitation was similar between the low- and high-dose groups (difference 1.9%, 95% confidence interval [CI] −14.8% to 18.4%). No significant difference was observed in sedation duration between the two groups (difference 0%, 95% CI −3.0% to 4.0%). While no additional ketamine was required in the high-dose group, four patients (7.4%) in the low-dose group required an additional half-dose (difference 7.4%, 95% CI −2.3% to 18.7%). Changes in vital signs were similar between the two groups. Conclusions: There was no significant difference in recovery agitation, sedation duration, and changes in vital signs between 0.5 and 1 mg/kg IV ketamine for procedural sedation in the ED.
Diagnostic importance of serum neopterin, procalcitonin and some acute phase proteins in cattle with lung hydatid cyst
(Hellenic Veterinary Medical Society, 2025) Akyüz, E.; Aydın, U.; Merhan, O.; Karakurt, E.; Sezer, M.; Batı, Y.U.; Yıldız, U.; Nuhoğlu, H.; Erkılıç, E.E.; Ölmez, N.; Özaydın, İ.; Gökçe, G.; Erdoğan, H.M.
In this study, it was aimed to determine the diagnostic importance of serum neopterin, procalcitonin, and some acute phase proteins in cattle with lung hydatid cysts. In the study, 30 cattle aged 2-8 years, Simmental or crossbred, constituted the patient group, and 10 healthy cattle in the same characteristics and age range constituted the control group. The cattle were included in the study after being diagnosed with lung hydatid cyst as a result of clinical, anamnesis, auscultation, radiographic examinations, laboratory and histopathological findings. Neopterin (21.60 nmol/L) and procalcitonin concentrations (146.77 ng/L) were significantly increased in the disease group compared to the control group (respectively: 7.22 nmol/L, 47.76 ng/L) (P<0.001). Haptoglobin (P<0.001) and ceruloplasmin (P=0.047) of the acute phase proteins werehigher in the patient group compared to the control group, while albumin was found to be lower (P=0.028). In conclusion, the evaluation of serum neopterin, procalcitonin, and some acute phase proteins in cattle with lung hydatid cysts was found to be important. Since hydatid disease is a zoonotic disease, it will be important to perform radiography scans and confirm the diagnosis with relevant biomarkers and take new protective measures. We think that the diagnosis will be strengthened by investigating neopterin and procalcitonin levels, especially in cattle with suspected lung cysts in radiographic findings.
Etiology of Hematospermia in Turkish Men: Multicentric Study
(Galenos Publishing House, 2025) Gönültaş, Serkan; Baydilli, Numan; Solakhan, Mehmet; Güzel, Ahmet; Kardaş, Sina; Demirci, Aykut
Hematospermia is defined as the presence of blood in the semen. The data regarding its etiology and management is variable across the literature. Aims: To investigate the etiology of hematospermia in Türkiye so as to contribute to the current management strategies for hematospermia. Methods: An online study protocol was published through the Turkish Urology Association communication network, and the centers that met the criteria were included in the study. All patients who presented with hematospermia complaints in the past 1 year were subjected to detailed anamnesis, physical examination, and routine laboratory tests. Based on the results, the patients were assigned to Group 1 (patients aged < 40 years with only one episode of hematospermia in the past 6 months) or Group 2 (patients with concomitant symptoms or ≥ 40 years or ≥ 2 times in the past 6 months). Radiological imaging was performed for the patients in Group 2. Results: A total of 199 patients (Group 1: 44, Group 2: 155; mean age: 43.07 ± 14.73 years; age range: 16-73 years) from across 42 cities and 22 different centers were enrolled in this study. In the etiological classification, inflammation was identified as the most common cause (n = 76, 38.1%). Idiopathic hematospermia was higher in Group 1 than in Group 2 (70.4% vs. 112.2%, respectively), and hematospermia was associated with malignancy in 9 (5.8%) Group 2 patients. Positivity was detected in urine or semen cultures in 20 (12.9%) patients, and hematospermia occurred after COVID-19 infection in 2 patients. A significant correlation was noted between patients showing no-concomitant symptoms and those showing idiopathic hematospermia, inflammation, malignancy, varicocele, and multiple etiological factors (p = 0.004, p = 0.028, p = 0.002, p = 0.001, p = 0.026, p = 0.016). The most common radiological findings were an increase in the prostate volume (n = 48, 30.9%) and changes in the signal intensities of the seminal vesicles (n = 29, 18.7%). Despite the use of different approaches to manage idiopathic hematospermia, the patients’ survey results were generally similar. Conclusion: Hematospermia in all age groups occurs generally due to self-limiting benign causes. Diagnostic imaging should therefore evaluate the elucidate etiology in patients with identified risk factors so as to avoid unnecessary treatments in idiopathic patients.
Levels of understanding cat body language of Cat owners in Türkiye
(Universidad del Zulia, Facultad de Ciencias Veterinarias, 2025) Erzurum, Onur; Kayar, Tamer
The aim of this study was to reveal how much the expressions cats show using their bodies are understood by their owners. A face-to-face survey was conducted on 1,459 cat owners between the year of ages 18-65 and living in seven regions of Türkiye. The participants were determined from people who come to animal hospitals or pet clinics and have cats at home, and these people participated in the survey voluntarily. When the distribution of the participants according to regions is analysed, the highest participation was from the Central Anatolia Region with 42.83%. The age group with the highest participation was the 18-25 age group. Among the questions in the survey, the ones with the highest percentage of correct answers were “Extremely Terrified” and “Disgusted,” while the question that received the most incorrect responses was “Anxious”. The rates of correct responses were nearly identical for both women (48.95) and men (48.03%). Among the participants of the survey, only one person answered all questions correctly. The region with the highest percentage of correct answers is Central Anatolia. Kruskal-Wallis test was performed in order to reveal the difference in the correct answers about the body language of cats according to age. Cat owners are not sufficient to understand the body language of cats and for this reason, they need to be informed and trained by experts on the body language of cats. When the literature review was conducted on the understanding of cat body language by cat owners, no other study covering the whole of Türkiye was found.
