Authors: AYDIN BERKTAS Ozlem , KESKIN Arif
Published: March 2022

The protection of N-Acetyl-L-cysteine (NAC) was investigated in the streptozocin-induced diabetes model in rat testicular tissues. In vivo biochemical mechanism was determined by measuring antioxidant parameters. The rats were randomly divided into 4 groups such as control, diabetes, diabetes+NAC and NAC. A single dose of intraperitoneal streptozotocin (IP STZ) (60 mg / kg body weight) was given to animals fasted overnight. Before injection and 72 hours after injection, blood glucose levels were measured from the tail vein with a glucometer. The blood glucose levels above 250 mg / dL were considered diabetic. Animals in groups 3 and 4 did not receive any treatment for four weeks after the diabetes model was established. Four weeks later, subjects in Groups 3 and 4 were given an IP injection of NAC (60 mg / kg, prepared in 0.9% NaCl solution daily) for 7 days. At the end of the applications, all animals were sacrificed and tissues were taken for antioxidant measurements. While the malondialdehyde (MDA) level increased in STZ-induced diabetic rat’s testicular tissues, it was brought to the control level with NAC treatment. The glutathione (GSH) and nitric oxide (NOx) level, superoxide dismutaze (SOD) and caalase (CAT) enzyme activities were found significantly reduced in the diabetic group. However, NAC treatment resulted in elevated these parameters.

Published: March 2022

n schizophrenia, the search for traditional therapies has a critical impact on early diagnosis, adherence to medication and the course of the disorder. Understanding the perspective of schizophrenic patients regarding traditional therapy is important to ensure their adherence to medical treatment. The present study aims to describe the traditional therapies used by patients with schizophrenia. This is a cross-sectional and descriptive study conducted with 180 schizophrenic patients who applied to a Community Mental Health Center. The sample was selected with the convenience sampling method, and data collection was performed by means of a ‘Demographic Information Form’ and a ‘Traditional Therapy Applications Form’. The mean age of the participants was 43.59±12.61 years, and the mean duration of the disorder was 13.10±9.28 years. While the majority of patients reported using regular pharmacological treatment, 36.7% reported receiving traditional therapy. After receiving a diagnosis of schizophrenia, the participants mostly had amulets/charms made for them (72.7%) and preferred visiting a religious practitioner/undergoing exorcism (69.7%). There was a significant difference between the use of traditional therapies and the age, marital status, education level, smoking and exercise habits (p<0.05). It has been observed that a high proportion of patients with schizophrenia receive medical treatment, and they also apply to traditional therapy practices. It appears advisable to implement programs to inform patients and their relatives/caregivers about the effectiveness of traditional therapies and the effects of such therapy on medical treatment.

Published: March 2022

In the present study, Energy Absorption Buildup Factor (EABF) and Exposure Buildup Factors (EBF) of the CR-39 and Trivex optical lenses are calculated by using the Geometric Progression (GP) fitting method based on ANSI/ANS-6.4.3 database. The study analyses comprehensively for different penetration depths within the energy range of 0.015 - 15 MeV up to 40 mfp. The buildup factors are calculated in the examined materials depending on the photon energy that arrives, the penetration depths, and the chemical composition of the material reach at maximum values in the energy region where inconsistent scattering interaction probabilities are intensive. The results show that the CR-39 optical lens had better radiation shielding performance. The suitability of the results is compared with the powerful software tools (EPICS2017 and Phy-X/PSD), which are preferred frequently in the literature to calculate radiation shielding parameters. It is found that the relative changes between the EPICS2017 and Phy-X/PSD software compared with the results of this study are about 8% and 9% for the CR-39 and Trivex optical lens, respectively. This indicates that the results from the study are in good agreement.

Published: March 2022

The method is of great importance in systems that include machine learning and classification steps. As a result, academics are constantly working to improve the process. However, the data pertaining to the methodology's performance is equally as valuable as the methodology's creation. While the data is utilized to show the result of the modeling process, it is critical to consider the proper labeling of the data, the technique of acquisition, and the volume. Obtaining data in certain sectors, particularly medical fields, can be costly and time consuming. Thus, data augmenting via classical and synthetic methods has recently gained popularity. Our study uses synthetic data augmentation since it is newer, more efficient, and produces the desired effect. Our study's goal is to classify a data collection of lung sounds into four groups using data augmenting. Obtaining and standardizing the wavelet scatter transformation of each cycle of lung sounds, splitting the transformed data into test and training, augmenting and classifying the training data. In the augmenting stage, we utilized ELM-AE, then ELM-W-AE, with six wavelet functions (Gaussian, Morlet, Mexican, Shannon, Meyer, Ggw) added. The SVM and EBT classifiers improved performance by 4% and 3% in ELM-W-AE compared to the original structure.

Published: March 2022

In present study, NiO:ZnO thin films in molar ratios of 1:0, 0:1, 3:1, 1:1 and 1:3 were formed on p-Si layers with aluminum (Al) bottom contact. Dynamic sol-gel spin coating method was used as coating method. Al top contacts were deposited on thin films and Al/NiO:ZnO/p-Si/Al photodiodes were fabricated. The structural and morphological properties of the photodiodes were determined by X-ray diffraction (XRD), emission scanning electron microscopy (FE-SEM), and energy dispersive X-ray spectroscopy (EDX). The photoresponse and electrical properties of the produced photodiodes were investigated by current–voltage (I–V) and capacitance-voltage (C-V) measurements. Al/NiO:ZnO/p-Si/Al photodiodes were successfully produced. It was determined that the thin films formed were composed of nanostructures. All photodiodes were found to be sensitive to light. It was seen that the photosensitivity of composite photodiodes was higher than the pure photodiodes and photosensitivity decreased as the ZnO ratio increased. It was determined that the most sensitive photodiode to light was the composite photodiode with a NiO:ZnO ratio of 3:1, and the highest photosensitivity was measured as 3.12 x 103 at 100 mW/cm2 light intensity in this photodiode. In all photodiodes, the capacitance values decreased as the frequency increased. The results show that by changing the NiO:ZnO ratio, the photoresponse and electrical parameters of the photodiodes can be controlled and the produced photodiodes can be used as a photosensor in solar tracking systems and optoelectronic applications.

In this paper, 15 different types of vegetables were automatically classified through transfer learning in deep learning. The dataset used in the study is large and consists of 21,000 vegetable images. These images in the dataset are divided into 3 groups as training, testing and validation. Within the scope of the study, all of these groups were combined and a large dataset was obtained. SqueezeNet architecture is used for feature extraction in the developed deep learning-based machine learning model. In addition, the ReliefF method was used for feature selection and the most significant features were determined by eliminating negative features. In the classification phase of the developed application, Linear Discriminant Analysis (LDA) method was preferred. In this study, Hold-Out and 10-fold cross-validation techniques were used. Approximately 99% accuracy value was obtained in both validation techniques. The obtained results of the study show that the proposed method can be used successfully in automatic vegetable classification.

The use of robotic systems has now become almost necessary in various fields. Of which, the realization of any hard or dangerous place requiring an implication of manipulation and locomotion, is necessarily entrusted to a mobile manipulator. In this work, we present a control approach that ensures the stability of the system, based on the linearization of feedback. We have determined the kinematic and dynamic models in order to apply the control with a high degree of accuracy. The approach is validated by simulation tests.

Solid state optical properties of fluorescent materials are important for many optical and electronic photonic devices such as organic light emitting diodes, frequency down-converters or luminescent solar concentrators. Perylene diimides (PDIs) represent one of the most popular organic semiconductors which find application in those phonic device applications. In this study, photophysical properties of two dibrominated PDI (DiBrPDIs), one of which contains a branched alkyl chain (2-ethylhexyl, 2-EH) and the other has an aromatic substituent (diisopropylphenyl, DIA) at the imide positions are comparatively studied. Besides their absorption and photoluminescence, lifetime and photoluminescence quantum yield (PLQY), photoinduced absorption properties (PIA) were also examined by fs-transient absorption spectroscopy. Due to their the same π conjugated system, DiBrPDI-DIA and DiBrPDI-2EH exhibited identical absorption and photoluminescence (PL) spectra in solution phase (λabs:527 nm and λPL:552 nm). However, in their film phases which were prepared at the same conditions, DiBrPDI-DIA (λPL-DIA:596 nm; PLQY:73.4%) presented a shorter PL wavelength with a higher PLQY than that of DiBrPDI-2EH (λPL-2EH:649 nm; PLQY:36.7%). 3-D investigations performed by using Chem3D pro software addressed the higher intermolecular distance between the perylene rings induced by the bulky DIA groups, as the main reason of this difference.

: One of the main objectives in neurosurgical procedures is the prevention of cerebral ischemia and hypoxia leading to secondary brain injury. Different methods for early detection of intraoperative cerebral ischemia and hypoxia have been used. Near-infrared spectroscopy (NIRS) is a simple, non-invasive method for monitoring cerebral oxygenation increasingly used today. The aim of this study was to systematically review the brain monitoring with NIRS in neurosurgery. The search process resulted in the detection of 324 articles using valid keywords on the electronic databases, including Embase, PubMed, Scopus, Web of Science, and Cochrane Library. Subsequently, the full texts of 34 studies were reviewed, and finally 11 articles (seven prospective studies, three retrospective studies, and one randomized controlled trial) published from 2005 to 2020 were identified as eligible for systematic review. Meta-analysis was not possible due to high heterogeneity in neurological and neurosurgical conditions of patients, expression of different clinical outcomes, and different standard reference tests in the studies reviewed. The results showed that NIRS is a non-invasive cerebral oximetry that provides continuous and measurable cerebral oxygenation information and can be used in a variety of clinical settings.

Background: Post spinal anesthesia hypotension (PSAH) is frequently encountered in anesthetic practice, especially during cesarean section. Ultrasound is a safe and easy technique for hemodynamic monitoring. Objectives: This study was conducted to assess the efﬁcacy of pre-operative inferior vena cava collapsibility index (IVCCI) and internal jugular vein collapsibility index (IJVCI) in predicting PSAH. Methods: This cross-sectional blinded study included 55 pregnant females prepared for elective cesarean section. They were divided into two groups based on the incidence of PSAH: (1) cases with PSAH (26 cases); and (2) cases without PSAH (29 cases). All the cases underwent ultrasound-guided measurement of IVCCI and IJVCI. The efficacy of these parameters was assessed in predicting PSAH. Results: Cases in both groups expressed non-significant differences regarding demographic data. However, IVCCI had mean values of 38.27 and 23.97%, while IJVCCI had mean values of 46.50 and 33.41%, respectively, in cases with and without PSAH. For IVCCI, using a cut-off point of 33% had sensitivity and specificity (84.6 and 93.1%, respectively) for predicting PSAH, with a diagnostic accuracy of 89.1%. IJVCI had sensitivity and specificity of 84.6 and 82.8%, respectively, for predicting the same complication using a cut-off value of 38.5%. Conclusion: IVCCI and IJVCI are efficacious and reliable tools in predicting PSAH in pregnant ladies undergoing cesarean section, with a slight superiority for IVCCI regarding specificity and accuracy.

: The treatment of pain, both acute and chronic, has been a focus of medicine for generations. Physicians have tried to develop novel ways to effectively manage pain in surgical and post-surgical settings. One intervention demonstrating efficacy is nerve blocks. Single-injection peripheral nerve blocks (PNBs) are usually preferred over continuous PNBs, since they are not associated with longer lengths of stay. The challenge of single injection PNBs is their length of duration, which at present is a major limitation. Novel preparations of local anesthetics have also been studied, and these new preparations could allow for extended duration of action of anesthetics. An emerging preparation of bupivacaine, exparel, uses a multivesicular liposomal delivery system which releases medication in a steady, controlled manner. Another extended-release local anesthetic, HTX-011, consists of a combination of bupivacaine and low-dose meloxicam. Tetrodotoxin, a naturally occurring reversible site 1 sodium channel toxin derived from pufferfish and shellfish, has shown the potential to block conduction of isolated nerves. Neosaxitoxin is a more potent reversible site 1 sodium channel toxin also found in shellfish that can also block nerve conduction. These novel formulations show great promise in terms of the ability to prolong the duration of single injection PNBs. This field is still currently in development, and more researchers will need to be done to ensure the efficacy and safety of these novel formulations. These formulations could be the future of pain management if ongoing research continues to prove positive effects and low side effect profiles.

Background: Several studies have examined the possible role of beta-blockers, including esmolol, in controlling intracranial pressure (ICP). This study aimed to evaluate the effect of esmolol on ICP in patients with severe traumatic brain injury. Methods: In this case-control study, all TBI patients with ICP > 20 cmH2O, who were admitted to ICU during the study period, were included. Some patients received standard treatment plus esmolol (500 μg/kg and then 50 mg/kg/min for 24 hours), and some others just received standard treatment with no esmolol. The patients were monitored, and the ICP measurement was performed via inserted intra-ventricular catheter. The ICP and vital signs were measured and recorded before, 8, 16, and 24 hours after starting the treatment in the two groups, and the findings were then compared. Results: Twenty-two patients (13 males and 9 females) were included in this study, of whom 12 patients received esmolol, and 10 patients were in the control group. The mean age of those who received esmolol was smaller than those who did not receive it (46.6 ± 18.5 vs. 62.3 ± 19.1 years; P = 0.08). Moreover, the mean length of the ICU stay was smaller in the esmolol receivers than the control group (5.6 ± 1.1 vs. 17.3 ± 7.7 days; P = 0.04 (there was no significant difference between the two groups in terms of mortality rates (P = 0.30). The variations of the vital signs over time was not significantly different between the two groups (P > 0.05); however, the mean of ICP was lower in those who received esmolol compared to the control group at all checkpoints (P < 0.05). Conclusions: Those patients with TBI who received esmolol as part of their ICP control management in ICU had lower ICP than those who received no esmolol.
