Özevren Hüseyin,İrtegün Sevgi,Deveci Engin,Aşır Fırat,Pektanç Gülsüm,Deveci Şenay 대한신경손상학회 2017 Korean Journal of Neurotrauma Vol.13 No.2
Objective: Traumatic brain injury causes tissue damage, breakdown of cerebral blood flow and metabolic regulation. Thisstudy aims to investigate the protective influence of antioxidant Ganoderma lucidum (G. lucidum) polysaccharides (GLPs)on brain injury in brain-traumatized rats. Methods: Sprague-Dawley conducted a head-traumatized method on rats by dropping off 300 g weight from 1 m height. Groups were categorized as control, G. lucidum, trauma, trauma+ G. lucidum (20 mL/kg per day via gastric gavage). Braintissues were dissected from anesthetized rats 7 days after injury. For biochemical analysis, malondialdehyde, glutathioneand myeloperoxidase values were measured. Results: In histopathological examination, neuronal damage in brain cortex and changes in blood brain barrier were observed. In the analysis of immunohistochemical and western blot, p38 mitogen-activated protein kinase, vascular endothelial growth factor and cluster of differentiation 68 expression levels were shown. These analyzes demonstrated the benefcial effects of GLPs on brain injury. Conclusion: We propose that GLPs treatment after brain injury could be an alternative treatment to decraseing inflammationand edema, preventing neuronal and glial cells degeneration if given in appropriate dosage and in particular time intervals.

QUATERNIONS AND HOMOTHETIC MOTIONS IN EUCLIDEAN AND LORENTZIAN SPACES
( Gülsüm Yüca ),( Yusuf Yayli ) 호남수학회 2023 호남수학학술지 Vol.45 No.2
In the present paper, we investigate homothetic motions determined by quaternions, which is a general form of our previous paper [20]. We introduce a transition between homothetic motions in 3D and 4D Euclidean and Lorentzian spaces. In other words, we give a new method that works as a handy tool for obtaining Lorentzian homothetic motions from Euclidean homothetic motions. Moreover, some remarkable properties of homothetic motions, which are given in former studies on this subject, are also examined by dual transformations. Then, we present applications and visualize them with 3D-plots. Finally, we investigate homothetic motions in dual spaces because of the importance in many fields related to kinematics.
Narrative differences between Orkhon inscriptions
Uzun, Gülsün Leylâ 한국이슬람학회 2010 한국이슬람학회논총 Vol.20 No.2
This study aims to demonstrate some of the discourse features of Tunyukuk scripts, a part of Orkhon inscriptions and compare it to the other parts, which are Bilge Kagan and Kül Tigin, in terms of its basic narrative discourse. The data will be analyzed using descriptive tools provided by narrative analysis and the rhetorical structure theory with a synchronic point of view. Tunyukuk will be the main text to be analyzed. and it will be compared to Kül Tigin to specify the discursive differences among them. Since Kül Tigin and Bilge Kagan have similar contents, Bilge Kagan will be excluded from this analysis. This study claims that even though these two scripts seem to report the same sequence of events, there is a drastic difference between them in terms of the presentation of their macro structures.

SOME RESULTS ON INVARIANT SUBMANIFOLDS OF AN ALMOST KENMOTSU (κ, μ, ν)-SPACE
( Mehmet Atçeken ),( Gülsüm Yüca ) 호남수학회 2021 호남수학학술지 Vol.43 No.4
In the present paper, we study the geometric properties of the invariant submanifold of an almost Kenmotsu structure whose Riemannian curvature tensor has (κ, μ, ν)-nullity distribution. In this connection, the necessary and sufficient conditions are investigated for an invariant submanifold of an almost Kenmotsu (κ, μ, ν)-space to be totally geodesic under the behavior of functions κ, μ, and ν.

The purpose of this study was to examine the effect of aurofilm masking agents applied to various metal alloys on the colorof porcelain in metal-ceramic restorations (MCRs). The study was conducted with 2 different base-metal alloys (Ni-Cr, Co-Cr)and 2 different noble alloys (Pd-based, Au-Pd) used for MCRs, as well as 1 high noble alloy (Au-based) that served as a controlgroup. Eight experimental groups (n=7) and 1 control group were used in this study. An aurofilm masking agent was appliedto 4 groups (AuPdM, PdM, CoCr, NiCrM). Opaque porcelain and dentin body porcelain were applied to all groups. CIEL*a*b* color coordinates were measured. The Pd group had the highest mean a* value (-5.82); however, in comparisonto the control group, the differences in a* values were statistically significant only for the Cr-Co alloy groups (CoCr andCoCrM). The Pd group had the highest mean b* value (7.89). The ΔE value (2.13) of the CoCr group was significantly higherthan all other alloy groups. Metal alloy substrate and aurofilm masking agents significantly affected the color of porcelainMCRs. However, color differences between base-metal and noble alloys and the control group were within clinically acceptablelimits (ΔE<3.5).

Introduction: To prevent and manage the societal and economic burden of occupational diseases (ODs), countries should develop strong prevention policies, health surveillance and registry systems. This study aims to contribute to the improvement of OD surveillance at national level as well as to identify priority actions in Turkey. Methods: The history and current status of occupational health studies were considered from the perspective of OD surveillance. Interpretative research was done through literature review on occupational health at national, regional and international level. Analyses were focused on countries’ experiences in policy development and practice, roles and responsibilities of institutions, multidisciplinary and intersectoral collaboration. OD surveillance models of Turkey, Belgium and the Netherlands were examined through exchange visits. Face-to-face interviews were conducted to explore the peculiarities of legislative and institutional structures, the best and worst practices, and approach principles. Results: Some countries are more focused on exploring OD trends through effective and cost-efficient researches, with particular attention to new and emerging ODs. Other countries try to reach every single case of OD for compensation and rehabilitation. Each practice has advantages and shortcomings, but they are not mutually exclusive, and thus an effective combination is possible. Conclusion: Effective surveillance and registry approaches play a key role in the prevention of ODs. A well-designed system enables monitoring and assessment of OD prevalence and trends, and adoption of preventive measures while improving the effectiveness of redressing and compensation. A robust surveillance does not only provide protection of workers’ health but also advances prevention of economic losses.

Autosomal recessive congenital ichthyosis (ARCI) is a group of diseases presenting as collodion baby at birth. ARCI is categorized as Harlequin ichthyosis, lamellar ichthyosis, and non-bullous congenital ichthyosiform erythroderma (NBCIE), bathing suit icthyosis (BSI) and others. We describe the case of a male newborn with NBCIE whose whole exome sequencing revealed two variants of TGM1 gene (NM_000359.3) in a compound heterozygous state: c.790C>T (p.Arg264Trp) in exon 5 and c.2060G>A (p.Arg687His) in exon 13. In the literature, the Arg264Trp variant has been reported as homozygous or compound heterozygous with other variants in patients with BSI. In contrast, the Arg687His variant has been reported only as homozygous in patients with BSI. To the best of our knowledge, this is the first case whose two compound heterozygous variants, exhibiting the NBCIE phenotype, instead of the BSI.

LTCC applications require densification at temperatures lower than 950 °C to allow co-firing with metal electrodes, lower dielectric constant to increase signal transmission speed, a thermal expansion coefficient matched to Si for reliability and higher thermal conductivity to dissipate heat. For this purpose, (SiO2–Al2O3–CaO)-based glass (50–60 wt%)/ceramic (Al2O3 or mullite) composites with nano-hBN (0–10 wt%) addition were investigated. Al2O3 was replaced by mullite to decrease dielectric constant and to match thermal expansion coefficient to Si, and hBN was incorporated to increase thermal conduc- tivity and to decrease dielectric constant. Densification at temperatures ≤ 900 °C was easily achieved for all compositions due to viscous sintering of the glass matrix. hBN did not react chemically with crystalline and amorphous phases, which effectively decreased dielectric constant and increased thermal conductivity. Hence, both mullite and nano-hBN strongly improved dielectric and thermal properties required for the LTCC applications. Dense mullite/glass (55 wt%) base composite with 10 wt% hBN addition was successfully engineered and had comparable dielectric and thermal properties (i.e., 2.3 gcm−3 after sintering at 900 °C, dielectric constant (loss) = 5.13 (0.003) at 5 MHz, thermal conductivity = 1.91 Wm−1 K−1 at 25 °C, and thermal expansion coefficient for the base composite = 4.75 ppm°C−1) with respect to the commercial LTCC products.
