Sur Aslihan,Iflazoglu Mutlu Seda,Tatli Seven Pinar,Seven Ismail,Aslan Abdullah,Kizil Meltem,Kulaksiz Recai,Yaranoglu Mustafa Hilmi,Esen Selim 한국독성학회 2023 Toxicological Research Vol.39 No.4

In this study, we investigated the effects of grape seed proanthocyanidin extract (GSPE) against the side effects of highdose administration of methylprednisolone (MP) in male rats. A total of 32 adult Wistar male albino rats were divided into four groups: (1) control (CON), received standard food only; (2) MP, received standard food + intraperitoneal injection of 60 mg/kg MP on day 7; (3) GSPE, received standard food + 200 mg/kg/day GSPE; and (4) MP + GSPE, received standard food + 200 mg/kg/day of GSPE + intraperitoneal injection of 60 mg/kg MP on day 7. All animals in the GSPE and GSPE + MP groups were treated once a day by oral gavage for 14 consecutive days. The feed intake of rats in the MP and MP + GSPE groups decreased significantly by 24.14% and 13.52%, respectively (p < 0.05). Administration of MP resulted in significant increases in serum concentrations of blood urea nitrogen (p < 0.001), glucose (p < 0.01), alkaline phosphatase, and adrenocorticotropic hormone (p < 0.05). High-dose MP administration significantly reduced catalase (p < 0.001) and glutathione peroxidase (p < 0.05) concentrations in the liver and kidney tissues of rats, while glutathione concentrations were only reduced in liver tissue (p < 0.05). The expression levels of Bcl-2 and TNF-α in liver, kidney, and testicular tissue were significantly increased, while the expression levels of caspase-3 were reduced (p < 0.001). Furthermore, sperm concentration was significantly affected by GSPE in rats induced by high-dose MP, and sperm loss was significantly reduced in MP + GSPE (p < 0.05). These findings suggest that GSPE could be useful as a supplement to alleviate MP-induced toxicity in rats.

Phytoceramide Alleviates the Carrageenan/Kaolin-Induced Arthritic Symptoms by Modulation of Inflammation

Sur Bongjun,Kim Mijin,Villa Thea,Oh Seikwan 한국응용약물학회 2023 Biomolecules & Therapeutics(구 응용약물학회지) Vol.31 No.5

Phytoceramide (Pcer) is found mainly in plants and yeast. It can be neuroprotective and immunostimulatory on various cell types. In this study, the therapeutic effect of Pcer was explored using the carrageenan/kaolin (C/K)-induced arthritis rat model and fibroblast-like synoviocytes (FLS). Pcer treatment (1, 10, and 30 mg/kg/day) were given to the arthritic rats for 6 days after disease induction. Weight distribution ration (WDR), knee thickness, squeaking score, serum levels of proinflammatory mediators, and histological analysis were measured and performed to evaluate arthritic symptoms in the rat model. In interleukin (IL)‑1β‑stimulated FLS, proinflammatory mediators were measured after Pcer (1-30 μM) treatment. Arthritic symptoms in rats with Pcer treatment were significantly decreased at days 4 to 6 after C/K arthritis induction. Inflammation in the knee joints were also significantly decreased in rats with Pcer treatment. Furthermore, in IL-1β‑stimulated FLS, the expressions of proinflammatory mediators were also inhibited by Pcer. As shown by the results, Pcer has anti-arthritic effects in the C/K rat model and in synovial cells, suggesting that Pcer has the potential to be a useful agent in arthritis treatment.

An efficient and secure navigation protocol based on vehicular cloud

Sur, Chul,Park, Youngho,Rhee, Kyung Hyune Taylor Francis 2016 International journal of computer mathematics Vol.93 No.2

<P>Vehicular cloud is the new paradigm of vehicular ad hoc networks (VANETs), which not only takes the recent advance of vehicular technology, but also keeps up with the trend of cloud computing for big data processing and complicated intelligent analysis over VANET environments. In this paper, we present a model for secure navigation systems based on vehicular cloud, which fully utilizes the advantages of cloud computing. In particular, we make up for the limitations of prior VANET-based secure navigation protocols and provide a stronger notion of security for secure navigation services in terms of insider threats and data leakage points of view. We propose a new secure and privacy-preserving navigation protocol based on vehicular cloud, which resolves the limitations of previous approaches. Moreover, the proposed protocol is highly efficient because it does not rely on bilinear pairing operations unlike prior secure navigation protocols in the literature. We demonstrate comprehensive analysis to confirm the fulfilment of the security objectives and the efficiency of the proposed protocol.</P>

Automatic Acquisition of Class-based Rules for Word Alignment

( Sur Jin Ker ),( Jason J. S. Chang ) 한국언어정보학회 1995 국제 워크샵 Vol.1995 No.-

In this paper, we describe an algorithm for aligning words with their translation in a bilingual corpus. Existing algorithms require enormous bilingual data to train statistical word-to-word translation models. Using word-based approach, frequent words with consistent translation can be aligned at a high precision rate. However, less frequent words or words with diverse translations usually do not have statistically significant evidence for confident alignment. Incomplete or incorrect alignments consequently result. Our algorithm attempts to handle the problem using a hierarchical class-based approximation of translation probabilities. The translation probabilities are estimated using class-based models on 3 levels of specificity. We found that the algorithm can provide translation probability for more word pairs at the cost of slightly lower degree of precision, even when a small corpus was used in training. We have achieved an application rate of 81.8% and precision rate of93.3%. The algOrithm also offer the advantage of producing word-sense disambiguation information.
