Authors: Su Tianhao , Cao Bin , Hu Shunbo , Li Musen , Zhang Tong-Yi
Published: November 2024

Discovering novel crystals is a highly effective way to develop new materials, though it presents significant challenges. Recently, many artificial intelligence (AI) generative methods have been developed to generate new crystals. In this work, we present a crystal generative framework based on Wyckoff generative adversarial network (CGWGAN) to efficiently discover novel crystals. The CGWGAN includes three modules: a generator of crystal templates, an atom-infill module, and a crystal screening module. The generator uses a generative adversarial network (GAN) to produce crystal templates embedded with asymmetry units (ASUs), space groups, lattice vectors, and the total number of atoms within the lattice cell, ensuring that the generated templates precisely match all requirements of crystals. These templates become crystal candidates after filling in atoms of different chemical elements. These candidates are screened by M3GNet and the passed ones are subjected to density functional theory (DFT)-based calculations to finally verify their stability. As a showcase, the CGWGAN successfully discovers seven novel crystals within the Ba-Ru-O system, demonstrating its effectiveness. This work provides a knowledge-guided Artificial Intelligence generative framework for accelerating crystal discovery.

Published: November 2024

The article addresses the development and evaluation of a novel environmentally-friendly cutting fluid prepared using sunflower oil and ZnO nanoparticles, specifically developed for use in metal machining processes. An experimental investigation was conducted to examine the impact of three adjustable input process factors: spindle speed, feed rate, and depth of cut on Mild steel. The investigation was carried out under two conditions: one with a 1%(weight) ZnO nano cutting fluid and the other with a 1.5%(weight) ZnO nano cutting fluid. The study focused on two factors: surface roughness and material removal rate (MRR), which were measured during the process of face-milling mild steel. The research aims to optimize the milling machine settings to improve the efficiency of machining mild steel as the work material. This will be achieved by using Response Surface Methodology (RSM). The ZnO nano-cutting fluid was created using a meticulous technique and its stability was assessed by several investigations. An investigation indicates that a ZnO nano-cutting fluid with a weight concentration of 1.5% is more stable. The process was enhanced by the use of a newly created integrated approach grounded on response surface methodology (RSM). The suitability of the model was confirmed by an analysis of variance (ANOVA). The analysis revealed that, when considering equal weights of responses, the ideal values for the input parameters of spindle speed, feed rate, and depth of cut were determined to be 408.081 rpm, 146.667 m/min, and 0.4878 mm accordingly, under the circumstances of using 1.5% weight of ZnO nano cutting fluid. The projected output responses were as follows: 777.920 for the MRR (Material Removal Rate) and 3.5297 for surface roughness. The composite attractiveness was calculated to be 0.61433. The suggested model in this research shows a fitting of over 80% with our studied values. This model may be used to discover the ideal states and enhance the efficiency of the milling process. The enhanced milling parameters exhibit the potential to enhance machining performance, offering useful insights for firms seeking environmentally sustainable alternatives for metal-cutting operations. This work contributes to the advancement of sustainable machining practices by developing a novel formulation for cutting fluid and providing a systematic approach to improving machining parameters.
Implementation and Performance Evaluation of Quantum Machine Learning Algorithms for Binary Classification
Authors: Ajibosin Surajudeen Shina , Cetinkaya Deniz
Published: November 2024

Quantum Machine Learning (QML) merges principles of Quantum Computing (QC) and Machine Learning (ML), offering improved efficiency and potential quantum advantage in data-driven tasks and solving complex problems. In binary classification, where the goal is to assign data into one of two categories, QML uses quantum algorithms to process large datasets efficiently. Quantum algorithms like Quantum Support Vector Machines (QSVM) and Quantum Neural Networks (QNN) exploit quantum parallelism and entanglement to enhance performance over classical methods. This research explores the use of QML algorithms for binary classification and compares their performance with classical ML methods. This study focuses on two common QML algorithms, Quantum Support Vector Classifier (QSVC) and QNN. We used the Qiskit software and did the experiments with three different datasets. Data preprocessing included dimensionality reduction using Principal Component Analysis (PCA) and standardization using scalers. The results showed that quantum algorithms demonstrated competitive performance against their classical counterparts in terms of accuracy, while QSVC performed better than QNN. These findings suggest that QML holds potential for improving computational efficiency in binary classification tasks. This opens the way for more efficient and scalable solutions in complex classification challenges and shows the complementary role of quantum computing.

Published: November 2024

Chemical investigation of the Antarctic sponge Suberites sp. has previously led to the identification of new suberitane derivatives, some of which show bioactivity toward the respiratory syncytial virus (RSV). Our ongoing NMR-guided investigation of new specimens of the sponge resulted in the isolation of five new analogs (1-5), the previously reported suberitenones A-D (6-9) and oxaspirosuberitenone (10). Suberitenone K (1) was characterized as the 8-keto derivative of suberitenone A, while three new phenols, suberitandiol (2), abeosuberitandiol (3), and furanosuberitandiol (4), and the degraded sesterterpene norsuberitenone B (5) were also found. 3 displays a ring contraction while 4 has a new dihydrofuran ring. Structural characterization was achieved by a combination of NMR, HR-MS, and X-ray diffraction. Suberitenone D and the new metabolite suberitenone K showed moderate activity towards RSV, while norsuberitenone B and furanosuberitandiol were found to have mild activity.

Published: November 2024

Many children suffer from neurodevelopmental aberrations that have long-term effects. To un-derstand the consequences of pathological processes during particular periods in neurodevelop-ment, one has to understand the differences in the developmental timelines of brain regions. The cerebellum is one of the first brain structures to differentiate during development, but one of the last to achieve maturity. This relatively long period of development underscores its vulnerability to detrimental environmental exposures throughout gestation. Moreover, as postnatal functional-ity of the cerebellum is multifaceted, enveloping sensorimotor, cognitive, and emotional domains, prenatal disruptions in cerebellar development can result in a large variety of neurological and mental health disorders. Here, we review major intrauterine insults that affect cerebellar devel-opment in both humans and rodents, ranging from abuse of toxic chemical agents such as alcohol, nicotine, cannabis and opioids, to stress, malnutrition as well as infections. Understanding these pathological mechanisms in the context of the different stages of cerebellar development in hu-mans and rodents can help us to identify critical and vulnerable periods and thereby to prevent the risk of associated prenatal and early postnatal damage that can lead to lifelong neurological and cognitive disabilities. The scope of the review is to raise awareness and to provide information for expecting parents, obstetricians, and other healthcare professionals to eventually de-sign strategies for preventing or rescuing related neurodevelopmental disorders.

Published: November 2024

Colon cancer (CC) is a significant public health concern. With Asian Americans (AA) representing a rapidly growing demographic in the United States, our study examined CC prevalence among AA. The study merged 2017-2021 Medical Expenditure Panel Survey and County Health Ranking. Our analysis calculated age-adjusted CC rates and examined prevalence across states. Regression analyses were conducted to study county-level risk factors of CC. The CC age-adjusted rate among AA increased five-fold, from 155 per 100,000 in 2017 to 753 per 100,000 in 2021. State-level disparities revealed the highest CC prevalence in Arkansas, Rhode Island, and New Hampshire. Not speaking other languages and having insurance were significantly associated with higher CC rates, suggesting barriers to preventions and higher use of screening (p<0.05). County-level analysis identified lower CC prevalence in regions with greater socioeconomic advantage (p<0.05). Socioeconomic advantage seemed to facilitate higher screening rates, translated into higher CC rates. Our findings underscore the need for early preventions to address rising CC rates among AA. Future research should also explore geographic to better understand the disparities in CC risk.

Authors: Wellauer Hanna , Gautier Emanuel , Klaeser Bernd , Meyer Niklaus , Meier Christoph , Wahl Peter
Published: November 2024

Periprosthetic fractures of the proximal femur are one of the most frequent causes of revision after total hip arthroplasty. Internal fixation may be chosen if the hip implant is stable or if a stable fixation may be obtained. Preservation of bone perfusion and adequate stability are essential for successful fracture healing. As presented in this report, a patient developed both osteonecrosis and atrophy of the cortical bone due to use of a specific plate to treat a periprosthetic fracture of the femur. An 82-year-old female sustained a periprosthetic fracture of the proximal femur two years after cemented hemiarthroplasty. The fracture was treated by plate fixation. Along the proximal femoral diaphysis, cerclages were applied to avoid interference of screws with the femoral stem. Due to postoperative restrictions and finally due to pain, the patient never could be mobilized out of a wheelchair. After 4 years, pain persisted while the fracture had healed without loosening of the joint replacement components. However, pronounced atrophy of the whole femur was present, with devitalized areas of the bone underlying the plate. When not strictly applied as an internal fixator at a distance from the bone, the plate model used in this case may disturb periosteal blood flow, causing osteonecrosis. Furthermore, high bending rigidity of the plate-bone construct may lead to stress shielding and atrophy. The case illustrates that design and mechanical properties of a plate are relevant in bone biology and healing.conclusions. Clinical trial abstracts should include items that the CONSORT group has identified as essential.

Published: November 2024

In this study, we explore the use of 3D convolutional neural networks (CNNs) for predicting internal temperature fields from the surface temperature, with a focus on applications where small temperature gradients, similar to those in the human body, are present. The network accuracy was evaluated under both ideal and non-ideal conditions which include noise and background temperature effects. In non-ideal scenarios, the network accurately reconstructed the 3D temperature field for small phantoms (e.g., 10 cm in diameter). However, as the size of the domain increased, the network’s predictive capacity diminished, particularly in regions far from the surface. To address this limitation, we introduced statistical uncertainty during training, simulating non-ideal conditions, in combination with a physics-informed loss function which embed the heat equation directly into the training process. This combination can improve the model’s performance, particularly in noisy environments, where traditional CNN architectures failed to reconstruct hot-spots in deeper regions. Our results suggest that combining deep learning with physical constraints offers a robust framework for non-invasive thermal imaging and other applications requiring high-precision temperature field reconstruction.
Syndecans in Aortic Aneurysm Pathogenesis and Course: A Narrative Review. Biomarkers and Targets?
Authors: Pisano Calogera , Asta Laura , Sbrigata Adriana , Balistreri Carmela Rita
Published: November 2024

Maintenance of the integrity of entire endothelium, glycocalyx included, and therefore of tissue aorta’s homeostasis, depends on the expressions of several molecular pathways and their interactions, such as syndecans molecules. Alterations in syndecans, i.e. quantitative or linking to their shedding, contributes to evocate endothelium dysfunction, which causes damage in the vessel wall due to the increased production of growth-stimulating and pro-inflammatory gene products. Inflammatory processes negatively affect the integrity of the endothelial glycocalyx, a dynamic layer of the luminal portion of endothelial cells composed of proteoglycans, glycoproteins, and glycosaminoglycans, i.e. syndecans. In turn, structural alterations of endothelial glycocalyx influence the coagulative state, increasing pro-thrombotic processes. The family of syndecans constitutes the major component of glycocalyx, or better the major source of cell surface heparan sulfate. It encompasses 4 components: syndecan-1, syndecan-2 and syndecan-4 (since syndecan-3 is expressed only in neural tissue), which have a fundamental role in regulating the events of acute and chronic aorta damage subsequently correlated with the formation of aneurysms. Considering such, the aim of our review is to highlight the current knowledge on the roles of syndecans, and based on the most recent literature, to analyze their relationship with the pathological processes of the aortic wall.

Authors: Fedorchenko Volodymyr , Yeroshenko Olha , Shmatko Oleksandr , Kolomiitsev Oleksii , Omarov Murad
Published: November 2024

Web applications, which are widely used to provide services and collect information, have become a major target for attackers, especially with the emergence of government services that process sensitive data. The .NET software platform, popular for developing web applications, includes built-in hashing algorithms (HA) and key generation functions (KDF) to protect passwords. However, these were developed over two decades ago for different levels of threats. More modern alternatives, such as Bcrypt, Scrypt, and Argon2, offer improved protection against modern GPU, ASIC, and FPGA attacks, but require third-party implementation. Given the critical role of password protection in protecting user information, this research investigates the effectiveness of various hashing mechanisms on the .NET platform, which is an urgent need for securing modern web applications. The subject of study in the article is the features of hashing algorithms built-in and available in the libraries of the .NET software platform for password protection as the main aspect of user authentication. The purpose of the work is to compare and analyse the hashing algorithms built-in and available in the libraries of the .NET software platform for password protection as the main aspect of user authentication. Objectives: to review built-in algorithms such as MD5, SHA and PBKDF2, as well as third-party implementations of modern key derivation functions such as Bcrypt, Scrypt and Argon2, and to investigate their performance and cryptographic strength. Methods used: This included measuring hashing speeds for different password sets and analysing attack resistance using tools such as Hashcat and data from independent security research. The results show that while built-in algorithms such as MD5 and SHA256 are fast, they do not provide protection against modern threats such as rainbow table attacks and GPU-accelerated brute-force attempts. PBKDF2, which is standard in ASP.NET Core Identity, provides better security but is vulnerable to attacks using specialised hardware. Among the modern algorithms, Argon2 demonstrated the best balance of security and performance, providing protection against GPU, ASIC, and FPGA-based attacks.  Conclusions. The study concluded that Argon2 is the recommended algorithm for password hashing on the .NET platform, while Bcrypt is a suitable alternative for legacy applications. PBKDF2 with a high number of iterations can still provide strong protection. A promising direction for further research may be to determine whether modern memory-intensive key derivation functions can be used to improve password security in .NET applications.

Authors: Tekin Fatih , Bilek Furkan
Published: November 2024

Objectives: The aim of this study was to investigate the factors underlying the fear of falling in Multiple Sclerosis (MS) patients and to determine the share of physical and psychological components in this fear.Materials and Methods: Patients between the ages of 18-65 years, diagnosed with Relapsing-Remitting form of MS were included in the study. Timed Up and Go Test (TUG) was used to assess gait functions and balance skills of patients during gait, Berg Balance Test (BBT) to assess balance skills in general, Fall Efficacy Scale-International (FES-I) to assess fear of falling, and Expanded Disability Status Scale (EDSS) to assess MS severity of the patients.Results: Forty-four patients (F:32 M:12) diagnosed with MS, with a mean age of 37.23±9.67 years, were included in our study. There was a statistically significant, positive and moderate correlation between the fear of falling and the number of attacks in the last 1 year (r=0.433, p=0.039), a statistically significant, positive and high-level correlation between fear of falling and falling history in the last 1 year (r=0.912, p=0.001), disability status (r=0.940, p=0.001) and TUG test (r=0.901, p=0.001) and a significant, negative and high-level correlation between fear of falling and balance skills (r=-0.944, p=0.001). According to the regression analysis, while the effects of falling history (p=0.043), BBT (p=0.025), TUG (p=0.004), and EDSS (p=0.007) on FES-1 were significant, the effect of TPLA was insignificant (p>0.05).Conclusion: Patients with MS are right about their fear of falling in parallel with their disability and balance-gait skills. However, this relationship is bidirectional, and the fear of falling has the potential to increase these limitations even more in MS patients whose functional activities are already restricted or going to be restricted.

Objective: To investigate the significance of vHIT (Video Head Impulse Test) in determining the efficacy of therapeutic maneuvers in individuals with posterior semicircular canal (SCC) BPPV. Materials and Methods: The study included 25 patients with posterior SCC BPPV (Study Group), 30 healthy individuals (Control Group). All individuals underwent otorhinolaryngologic examination, audiological evaluation, videonystagmography, vHIT and completed Dizziness Handicap Inventory (DHI) and Visual Analogue Scale (VAS). Modified Epley Maneuver was performed 3 times at an interval of 3 days. The vHIT, DHI and VAS were re-administered to these individuals 1 week after improvement was detected in positional nystagmus. Results: There was no significant difference between the study and control groups in terms of vHIT gains for all bilateral SCCs before therapeutic maneuver (p>0.05). In the study group, there was no significant difference between vHIT gains of all bilateral SSCs before and after therapeutic maneuvers (p>0.05). No asymmetry or refixation saccades (overt and covert) were observed in any of the individuals in both groups during all measurements. Compared to before therapeutic maneuvers, there was a significant decrease in dizziness-related disability level assessed by DHI and intensity of dizziness assessed by VAS in the study group after the improvement (p<0.001). Conclusion: It was found that vHIT was not a diagnostic test in BPPV and in terms of evaluating the efficacy of therapeutic maneuvers. Subjective evaluations determining the intensity of dizziness and level of dizziness-related disability in BPPV provided supportive information in diagnosis and in determining the efficacy of therapeutic maneuvers.

Amaç: Bu çalışma hospitalize hastaların beslenme durumlarının yemekhane hizmeti memnuniyetleriyle ne derece ilişkili olduğunu araştırmak amacıyla yapılmıştır. Gereç ve Yöntem: Kesitsel bir araştırma olan bu çalışma, Kasım 2019-Aralık 2019 tarihleri arasında yapılmıştır. Katılımcılar Muş Devlet Hastanesi kliniklerinde yatmakta olan ve en az 2 ana öğünü hastane yemeklerinden tüketen 18 yaş üzeri gönüllü hastalardan oluşmuştur. Nutrisyonel Tarama Aracı (NRS-2002), Hastane Yiyecek Hizmetleri Hasta Memnuniyet Anketi (HYHHM) ve demografik bilgi formu olmak üzere 3 bölümden oluşan anket formu, katılımcılara yüz yüze uygulanmıştır. Elde edilen veriler SPSS 23.0 istatistik programı ile analiz edilmiştir. Bulgular: Çalışmaya dâhil edilen 109 katılımcıdan 25’inin malnütrisyon riski altında olduğu saptanmıştır. HYHHM ölçeğinin ortalama puanı 71,7±1,21 olup katılımcıların memnuniyet düzeylerinin en yüksek olduğu faktörlerin servis personelinin durumu ve çevresel faktörler olduğu saptanmıştır. Fakat katılımcıların malnütrisyon riski altında olup olmamalarıyla, hastane yiyecek hizmetlerinden genel memnuniyet durumları arasında anlamlı bir ilişki bulunamamıştır (r<0,2, p>0,05). Sonuç: Toplu beslenme sistemlerinin yatan hastaların beslenme durumu üzerinde önemli bir etken olduğu gerçeği yadsınamasa da çalışmanın anlamlı bir sonuç ortaya koyamadığı görülmüştür. Literatürde aynı hipotezin sorgulandığı benzer çalışmalar incelendiğinde bu çalışmanın örneklem sayısı ve katılımcıların hastanede yatış süresi noktalarında kısıtlı olduğu düşünülmektedir. Bu konuda daha fazla değişkeni kapsayan yeni çalışmalara ihtiyaç vardır.

Dünya Sağlık Örgütü tarafından pandemik olarak ilan edilen ve ülkemiz genelini de kısa sürede etkisi altına alan yeni Corona Virüs Hastalığı (COVID-19), çok kritik bir toplum sağlığı problemidir. Yaygın olarak ateş, öksürük ve kas ağrısı/ halsizlik gibi klinik semptomlarla başlayarak ilerleyen bu viral enfeksiyonun bulaşma yolları direkt temas, damlacık ve aerosol iletimidir. Diş tedavileri sırasında oluşan aerosollerin hekimlere, yardımcı personele ve ortamda bulunan diğer kişilere enfeksiyonu yayma potansiyeli oldukça yüksektir. Bu riski tamamen ortadan kaldırmak mümkün olmasa da alınan basit ek önlemler ile minimuma indirmek mümkündür. Bu makalede, COVID-19 enfeksiyonunun epidemiyolojisi, semptomları ve bulaşma yolları gözden geçirilerek, güvenli diş hekimliği uygulamaları için enfeksiyon kontrol stratejileri ve alınabilecek ek önlemler değerlendirilmektedir.

Published: November 2024

Objectives: The purpose of this study was to evaluate the exercise adherence of the patients according to recommended home exercice program and to determine which exercises were performed more accurately. Materail and Method: 121 consecutive patients who applied to the Physical Medicine and Rehabilitation Department of Hacettepe University Hospital due to low back pain and who were recommended home exercise program were included in the study. The flexion and extension exercises were given. On the 10th day following the introduction of the home program, the patients were invited for first control to assess the accuracy of the practice of the exercises. The accuracy of each exercise was analyzed by the physiotherapists (Likert type scoring system from 0 to 4). After 1 month, the patients were called for the second check of the correctness of the application of exercises. The same assessment was repeated. Findings: While the number of patients was 121 at the beginning, the number of patients in the first control decreased to 73, the number of patients in the second control decreased to 21 after 1 month. A statistically significant increase was found for only isometric strenghtening exercises in terms of the difference in accurate application of exercises between second and first assesstments (p <0.05). Conclusion: It is thought that it would be beneficial to carry out further studies to examine effects of combined interventions to ensure adherence to home exercise program.

Published: November 2024

Lenfoma hastalarına verilen hemşirelik bakımının, bakım verenlerde bireysel doyum duygusunu artırma, kişisel gelişim sağlama, bakım verme sonucu yaşanılan deneyimin gücü sayesinde anlam bulma, büyük oranda sevgi ve samimiyetin artması ve saygı duyma gibi olumlu katkılar sağladığı belirtilmiştir. Ancak bakım veren aile üyelerinin aile ve evlilik içi ilişkilerde zorluk, günlük aktivitelerde kısıtlanma, sosyal rollerde çatışma, fiziksel sağlıkta bozulma gibi sorunlar yaşadıkları bildirilmiştir. Bakım verenlerdeki depresyon, yorgunluk, uyku bozukluğu ve düşük öz-yeterlik düzeyinin bakım yükü üzerinde önemli bir etkiye sahip olduğu bulunmuştur. Ayrıca bakım veren aile üyelerinin yüksek düzeyde finansal sıkıntı yaşadığı, kaygı ve depresyondan yakındığı saptanmıştır. Literatürde bakım verenlerin bakım yükünü azaltabilmek için; bakım verenlerin fiziksel, psikolojik ve finansal alanlarda yaşadıkları sorunlara yönelik uygun bakım planlarının geliştirilmesi, sağlık profesyonelleri tarafından desteklenmesi, duygusal destek grupları gibi destekleyici kaynaklar sağlanması, müdahale programlarının geliştirmesi, hasta ve bakım veren aile üyelerinin fiziksel, psikososyal ve ruhsal gereksinimlerini karşılayan özel bir hizmet modelinin geliştirilmesi önerilmiştir. Bu derleme makalesi lenfoma hastalarıyla yaşayan aile üyelerinin bakım yükünün incelendiği literatür araştırmalarını gözden geçirmek, bakım yükünü değerlendirmek ve yapılacak hemşirelik girişimlerine yol göstermek amacı ile yazılmıştır.

Authors: Kumdakcı Sermin , Özer Fulya , Erbek Seyra , Özlüoğlu Levent
Published: November 2024

Amaç: Orkestra sanatçılarında afferent işitme sistemini saf ses odyometri, yüksek frekans odyometri, geçici uyarılmış otoakustik emisyon ile; efferent işitme sistemini ise medial olivokoklear kompleks supresyon testi ile incelemektir. Gereç ve Yöntem: Aynı orkestrada çalan en az 5 yıl deneyimi olan 30 sanatçı ve kontrol grubu olarak müzik icra etmeyen 30 gönüllü alınmıştır. Saf Ses Odyometri (SSO) ve yüksek frekans odyometri ile işitme eşikleri değerlendirilmiştir. Transient uyarılmış otoakustik emisyon (TEOAE) testiyle ilk olarak kontralateral akustik stimülasyon (KAS) verilmeden önce ölçümler alınmış, daha sonra 70 dB dar band gürültü ile KAS verilerek aynı anda TEOAE testiyle medial olivokoklear kompleks refleksi (MOCR) ölçülmüştür. Ortalama prova süreleri günlük 4 saat; ortam gürültüsüne maruz kalma süreleri haftada 20-35 saat arasında değişmektedir. Bulgular: SSO eşiklerine göre; orkestra çalışanlarında 16 kHz’de özellikle sol kulakta anlamlı bir eşik yükselmesi tespit edilmiştir (orkestra grubu 42,17 dB; kontrol grubu 31,83 dB). TEOAE amplitüdleri, orkestra sanatçılarında tüm frekanslarda anlamlı derecede azdır (p<0.001). Orkestra sanatçılarında kontralateral akustik stimulasyon verildiğinde; 1, 2,4 ve 8 kHz frekanslarında anlamlı olarak TEOAE emisyon değerlerinde belirgin bir azalma tespit edilmiştir (p<0,05). Orkestra sanatçılarında prova süresi arttıkça TEOAE değerlerinde azalma gözlenirken; kontralateral supresyon değerlerinde anlamlı bir farklılık olmamıştır. Sonuç: Orkestrada çalan sanatçıların işitme sistemi değerlendirilmesinde, saf ses odyometri tek başına yeterli değildir. İşitme takibinde yüksek frekans odyometri ve otoakustik emisyonun beraber kullanımının gerekli olduğu bu çalışmada vurgulanmaktadır. Orkestra sanatçılarında medial olivary kompleks refleks aktivitesinin değerlendirilmesi önemli olmakla beraber müzisyenlerin işitme takibinde medial olivary kompleks refleks aktivitesinin tek başına kullanımı ile ilgili prospektif uzun dönem çalışmalara ihtiyaç vardır.
