          Evaluation of Mixtures of Certain Market Wastes as Silage

          Ozkul,,H.,Kilic,,A.,Polat,,M. Asian Australasian Association of Animal Productio 2011 Animal Bioscience Vol.24 No.9

          The aim of this study was to determine the usefulness of vegetable wastes as silage for ruminants. Varying amounts of wheat straw (WS), wheat bran (WB) and salt (S) were combined with minced vegetable wastes (VW) during ensilage. Seven different ingredient combinations were investigated viz: 100% VW (Group I, control), 90% VW+9% WS+1% S (Group II), 80% VW+15% WS+4% WB+1% S (Group III), 70% VW+20% WS+9% WB+1% S (Group IV), 90% VW+9% WB+1% S (Group V), 80% VW+15% WB+4% WS+1% S (Group VI) and 70% VW+20% WB+9% WS+1% S (Group VII). The inclusion of straw and bran increased (p<0.01) the DM content of silage. The highest contents of the pure silage were CP (p<0.001), EE (p<0.01) and NFE (p<0.05). NDF contents of VW silage and group V were significantly lower and especially the VW silage was found to have the lowest ADL content (p<0.01). The in vitro ME values of VW silage and bran added silage were higher than other groups (p<0.01). pH, lactic acid and acetic acid values of silage groups were changed between 4.09-4.20, 2.43-3.46% and 0.60-0.86%, respectively. In conclusion, different mixtures of VW have a high ensilage capacity and can serve as an alternative roughage source for ruminants. The addition of 9% bran significantly improved the silage in view of both dry matter content and nutritive value.

          Invention of the Guide Catheter Irrigation Monitoring Device for Neuroendovascular Therapy

          Ozkul,,Ayca,Park,,Jong-Hyun,Shin,,Dong-Seung,Yilmaz,,Ali,Kim,,Bum-Tae The Korean Neurosurgical Society 2017 Journal of Korean neurosurgical society Vol.60 No.4

          Objective : The thromboembolic events during neuroendovascular therapy (NET) are the major complications of concern that can be occasionally fatal. The thrombotic occlusion of the guide catheter for NET is thought to be the risk of the thromboembolic events. We have developed an idea for inventing the monitoring system of the continuous irrigation through the guide catheter. We herein present a unique invention of the guide catheter irrigation monitoring device. Methods : We have developed ideas for preventing the thrombotic occlusion of the guide catheter. In order to design a convenient device working in the practical use, we have consulted and shared the ideas with the electrical engineers about putting the invention. Results : The guide catheter irrigation monitoring device (GCIMD) consisted of three parts of optical sensor, main body and electric adapter. In brief, the basic principles of working of the GCIMD are as follows. The optical sensor is attached to the dripping chamber of the line to irrigation solution. The main body had the small light and speaker to make an alarm sounds. The sensor monitors the dripping of flush solution. If the dripping stops more than three seconds, a warning alarm has been activated. So, the operating physicians can concentrate and check the guide catheter irrigation. After the use of the GCIMD, there was no major thromboembolic complication in conjunction with the thrombotic occlusion of the guide catheter in our institute. Conclusion : We have developed a brilliant invention of the GCIMD for NET.

          Histopathological and biochemical findings of congenital copper deficiency: are these similar to those of caprine arthritis-encephalitis?

          I.,Ayhan,Ozkul,G.,Alcigir,A.,Sepici-Dincel,A.,D.,Yonguc,A.,Akcora,J.,Turkaslan 대한수의학회 2012 JOURNAL OF VETERINARY SCIENCE Vol.13 No.1

          This study was done after identifying animals with a twisted carpal joint in goat herd. These included a kid goat walking on its articulus carpii and a newborn goat with a stiff leg. Necropsies of the diseased goats revealed swollen carpal joints that were twisted backwards. Arthritis was observed during microscopic examination of the carpal joints. Very low levels of eosinophil, leucocyte, and lymphocyte cell infiltration were found in the central nervous system and meninges. Serum copper levels were significantly decreased in most of the animals. All of these results led us to diagnose the animals with swayback disease.

          Morphological Assessment of Cadaveric Radial, Brachial and Subclavian Arteries : A Neurointerventional Approach

          Yilmaz,,Ali,Ozkul,,Ayca,Shin,,Dong,Seong,Im,,Soo-Bin,Yoon,,Seok-Mann,Kim,,Bum-Tae The Korean Neurosurgical Society 2015 Journal of Korean neurosurgical society Vol.58 No.6

          Objective : The transradial catheterization (TRC) is becoming widespread, primarily for neurointerventions. Therefore, the evaluation of radial artery puncture in clinical practice and a better understanding of the anatomy are important to improve the safety of neuroendovascular surgery. Methods : Ten formalin-fixed adult Korean cadavers were dissected to expose radial artery (RA), brachial artery (BrA) and subclvian artery (ScA), bilaterally. Vessel lengths and diameters were meaured using a caliper and distance between the specific point of vessels and the anatomical landmarks including the radial styloid process, the medial epicondyle of the humerus, the sternoclavicular joint, and the vertebral artery orifice were also measured. Results : The average length between the radial (RAPS) and the BrA puncture sites (BrAPS) and between the vertebral artery orifice (VAO) and the BrA bifurcation (BrAB) did not differ between sides (p>0.05). The average length between the radial styloid process (RSP) and the RAPS was $13.41{\pm}2.19mm$, and the RSP was $26.85{\pm}2.47mm$ from the median nerve (MN). The mean length between the medial epicondyle (ME) and the BrAPS as $44.23{\pm}5.47mm$, whereas the distance between the ME and the MN was $42.23{\pm}4.77mm$. The average VAO-ScA angle was $70.94{\pm}6.12^{\circ}$, and the length between the ScA junction (SCJ) and the VAO was $60.30{\pm}8.48mm$. Conclusion : This study provides basic anatomical information about the radial artery and the brachial route and can help improving new techniques, selection of size and shape of catheters for TRC. This can help neurointerventionists who adopt a transradial neuroendovascular approach and offers comprehensive and safe care to their patients.

          Autism spectrum disorders (ASD) is characterized by three core symptoms with impaired reciprocal social interaction and communication, a pattern of repetitive behavior and/or restricted interests in early childhood. The prevalence is higher in male children than in female children. As a complex neurodevelopmental disorder, the phenotype and severity of autism are extremely heterogeneous with differences from one patient to another. Genetics has a key role in the etiology of autism. Environmental factors are also interacting with the genetic profile and cause abnormal changes in neuronal development, brain growth, and functional connectivity. The term of exome represents less than 1% of the human genome, but contains 85% of known disease-causing variants. Whole-exome sequencing (WES) is an application of the next generation sequencing technology to determine the variations of all coding regions, or exons of known genes. For this reason, WES has been extensively used for clinical studies in the recent years. WES has achieved great success in the past years for identifying Mendelian disease genes. This review evaluates the potential of current findings in ASD for application in next generation sequencing technology, particularly WES. WES and whole-genome sequencing (WGS) approaches may lead to the discovery of underlying genetic factors for ASD and may thereby identify novel therapeutic targets for this disorder.

          mRNA Expression Level of Interleukin Genes in the Determining Phases of Behçet's Disease

          Serpil,Taheri,Murat,Borlu,Cem,Evereklioglu,Sevda,Yesim,Ozdemir,Yusuf,Ozkul 대한피부과학회 2015 Annals of Dermatology Vol.27 No.3

          Background: Behçet's disease (BD), first described in 1937 as a triadic complex of symptoms (oral aphthae, genital ulcers, and hypopyon uveitis), is a chronic, relapsing, multisystemic idiopathic inflammatory disease. Objective: The objective of this study was to investigate the usability of messenger RNA (mRNA) expression of cytokine genes for following up patients with BD and also assess polymorphisms in these genes as to how they influence mRNA expression. Methods: This study investigated the role of the IL1A −889(C/T), IL1B − 511(C/T), and IL2 −330(T/G) polymorphisms by polymerase chain reaction (PCR)-restriction fragment length polymorphisms and the expression levels of the genes by real- time PCR in BD. Results: The frequency of the IL2 −330 G allele was found to be significantly higher in patients with BD. A decreased level of IL1A gene expression was found in the patient group with clinically active BD compared to controls. Increased IL1B gene expression levels werefound in patient groups with active, inactive, or ocular BD (p<0.001). IL2 gene expression level manifested no significant change compared to controls in the patient group with clinically active BD; it increased in the groups with clinically inactive BD or ocular involvement. Conclusion: IL1A, IL1B, and IL2 gene expression, and IL2 promoter polymorphisms, may be valuable markers for predicting risk in the development of BD. We believe that the results reveal the importance of achieving a better understanding of BD and the prospects of developing future therapeutic strategies.
