  • Dexmedetomidine Mitigates LPS-Induced Acute Lung Injury in Rats Through HMGB1-Mediated Anti- Inflammatory and Antioxidant Mechanisms
    Revista Argentina de Clínica Psicológica 2020, Vol. XXIX, N°4, 377-383 377 DOI: 10.24205/03276716.2020.837 Dexmedetomidine Mitigates LPS-Induced Acute Lung Injury in Rats Through HMGB1-Mediated Anti- Inflammatory and Antioxidant Mechanisms Ning Lva*，XiaoYun Lib ABSTRACT Purpose: To investigate the effect of dexmedetomidine on lipopolysaccharide (LPS)- induced acute lung injury in rats, and the underlying mechanism. Methods: Healthy male SD rats (n=54) were randomly divided into three groups: normal, model and dexmedetomidine groups, with 18 rats in each group. Rats in the model and dexmedetomidine groups were given LPS at a dose of 8 mg/kg, to establish a model of acute lung injury. Rats in the dexmedetomidine group were injected intraperitoneallywith dexmedetomidine at a dose of 50 μg/kg prior to establishment of the model, while rats in the normal group received intraperitoneal injection of normal saline in place of dexmedetomidine. Hematoxylin and eosin (H&E) staining was used to observe changes in lung tissue in each group.Changes in wet/dry weight ratio of lung tissue were compared among the groups. Enzyme-linked immunosorbent assay was used to determine the expressions of inflammation indices i.e. interleukin-6 (IL-6), tumor necrosis factor-α (TNF- α), and interleukin-1β (L-1β)] in lung tissue. Levels of MDA were measured with thiobarbituric acid method. Superoxide dismutase (SOD) activity was assayed through enzyme rate method, while nitric oxide was measured using nitrate reductase assay.The expression levels of high mobility group protein B1 (HMGB1), p-PI3K, p-Akt, p-IκB, p-NF- κB, and Toll-like receptor 4 (TLR4) in lung tissue were determined with Western blotting.

  • Mobile Code Anti-Reversing Scheme Based on Bytecode Trapping in ART
    sensors Article Mobile Code Anti-Reversing Scheme Based on Bytecode Trapping in ART Geonbae Na 1, Jongsu Lim 1, Sunjun Lee 2 and Jeong Hyun Yi 2,* 1 School of Computer Science and Engineering, Soongsil University, Seoul 06978, Korea; [email protected] (G.N.); [email protected] (J.L.) 2 School of Software, Soongsil University, Seoul 06978, Korea; [email protected] * Correspondence: [email protected] Received: 31 March 2019; Accepted: 6 June 2019; Published: 10 June 2019 Abstract: As interest in Internet of Things environments rapidly increases throughout the IT convergence field, compatibility with mobile devices must be provided to enable personalized services. The security of mobile platforms and applications is critical because security vulnerabilities of mobile devices can be spread to all things in these environments. Android, the leading open mobile platform, has long used the Dalvik virtual machine as its runtime system. However, it has recently been completely replaced by a new runtime system, namely Android Runtime (ART). The change from Android’s Dalvik to ART means that the existing Dalvik bytecode-based application execution structure has been changed to a machine code-based application execution structure. Consequently, a detailed understanding of ART, such as new file formats and execution switching methods between codes, is required from the viewpoint of application security. In this paper, we demonstrate that an existing Dalvik-based application vulnerability can be exploited as-is in ART. This is because existing Dalvik executable files coexist in the ART executable file, and these Dalvik bytecodes and compiled machine codes have one-to-one mapping relationships.

  • Nacldroid: Native Code Isolation for Android Applications
    NaClDroid: Native Code Isolation for Android Applications Elias Athanasopoulos1, Vasileios P. Kemerlis2, Georgios Portokalidis3, and Angelos D. Keromytis4 1 Vrije Universiteit Amsterdam, The Netherlands [email protected] 2 Brown University, Providence, RI, USA [email protected] 3 Stevens Institute of Technology, Hoboken, NJ, USA [email protected] 4 Columbia University, New York, NY, USA [email protected] Abstract. Android apps frequently incorporate third-party libraries that contain native code; this not only facilitates rapid application develop- ment and distribution, but also provides new ways to generate revenue. As a matter of fact, one in two apps in Google Play are linked with a library providing ad network services. However, linking applications with third-party code can have severe security implications: malicious libraries written in native code can exfiltrate sensitive information from a running app, or completely modify the execution runtime, since all native code is mapped inside the same address space with the execution environment, namely the Dalvik/ART VM. We propose NaClDroid, a framework that addresses these problems, while still allowing apps to include third-party code. NaClDroid prevents malicious native-code libraries from hijacking Android applications using Software Fault Isolation. More specifically, we place all native code in a Native Client sandbox that prevents uncon- strained reads, or writes, inside the process address space. NaClDroid has little overhead; for native code running inside the NaCl sandbox the slowdown is less than 10% on average. Keywords: SFI, NaCl, Android 1 Introduction Android is undoubtedly the most rapidly growing platform for mobile devices, with estimates predicting one billion Android-based smartphones shipping in 2017 [12].
