We present the case of a 24-year-old Caucasian man, who developed a scaly erythematous skin rash after the second dose of coronavirus disease 2019 (COVID-19) vaccination with Comirnaty (BNT162b2, BioNTech/Pfizer; Pfizer, New York, NY, USA) and proved positive for Epstein-Barr virus (EBV) reactivation. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA vaccines have been associated with an up-regulated T helper type 1-cell response, possibly favoring an immune system imbalance. Also, EBV reactivation has been postulated after COVID-19 vaccination, but only in the immunosuppressed. Noteworthy we report the first case of EBV viral reactivation associated with cutaneous manifestations in an immunocompetent patient after the COVID-19 vaccine.

Radiation-induced liver disease (RILD) has been characterized as a veno-occlusive disease with anicteric elevation of alkaline phosphatase (ALP). However, some RILD patients present with elevated transaminase levels rather than with anicteric elevation of ALP, and these findings are common in the Asia-Pacific region where hepatitis B virus (HBV) infection is associated with 70~90% of hepatocelluar carcinoma (HCC) cases. In addition, the development of RILD is more common in patients with hepatitis B virus-related HCC. These findings indicate that susceptibility to RILD might be different in HBV carriers and non-carriers, and moreover, RILD in patients with HBV-related HCC might be associated with another unique pathogenesis such as HBV reactivation. However, HBV reactivation after hepatic irradiation has been reported in only a few studies. This study reports three cases of HBV reactivation alter hepatic tomotherapy for management of HCC.

Targeted memory reactivation (TMR) is a method whereby cues associated with previous learning are used to externally reactivate aspects of this learning. Research findings demonstrate that TMR can be a useful tool to enhance memory consolidation during sleep in both animals and humans, especially in the declarative/spatial domain. Neurocognitive processing during sleep with covert cueing via auditory or olfactory stimulation can benefit memory storage. These beneficial effects on memory consolidation during sleep are associated with the activation of memory-related brain areas. The purpose of the present review is to provide a short overview of the findings of studies that adopted the TMR method of sleep-dependent memory consolidation and to suggest the potential applications of TMR in variable areas.

Purpose: We previously reported that concurrent reactivation of latent Epstein-Barr virus (EBV) in children with hepatitis A virus (HAV) infection is common and EBV reactivation with HAV infection adversely affects the clinical features of hepatitis. However, the incidence of concurrent reactivation was not accurate because the detection of EBV reactivation was based on serologic methods. Therefore, we studied the effects of polymerase chain reaction (PCR)-proven EBV reactivation, thus a more precise concurrence, on acute HAV infection in children. Methods: PCR were conducted in 34 patients, who had enrolled previous study and diagnosed with acute HAV infection between January 2008 and June 2010. Their medical records were reviewed. Results: Among 34 patients with acute HAV infection, 12 patients (35.3%) had EBV reactivation which was proven using serologic and molecular biologic techniques. There were significant differences in the peak levels of AST and ALT between the reactivated and non-reactivated groups (p=0.001 and p<0.001, respectively). The duration of full recovery from hepatitis was more prolonged in the reactivated group (p<0.001). Clinical parameters, such as serum protein (p<0.001) and albumin concentrations (p<0.001), atypical lymphocyte count (p=0.001), prothrombin time-international normalized ratio (PT-INR, p<0.001), and splenomegaly (p<0.001), showed significant differences. The clinical features in the reactivated sub-group >10 years of age revealed more liver dysfunction compared to the non-reactivated sub-group. A comparison with a previous study was performed. Conclusion: PCR-proven reactivation of latent EBV in children with HAV infection is common and EBV reactivation with HAV infection adversely affects the clinical features of hepatitis, especially in older children.

The reactivation for Art & Culture Content Space in Gangwon province need new turning point according to new approach with internal and external change. That should be established in sustainable possibility model with preexisted natural advantage instead of economical depression and global warming of in these days. That is not a choice to get a successful construction of art & culture content space in Gangwon province. Throughout of reactivation of art & culture content space in Gangwon province, this proposal should go on with diversity of culture and concrete art & culture educational program absolutely to get a goal in regional economical success and social good influence. Already Yeongwol region had lots of art & cultural spaces and developmental strategy compared with other regions in decade. In these points, I choose this region and would like to research Yeongwol region in limit. Thus I would examine and study about art & culture content space in Yeongwol region. And I will concretely suggest that this proposal is composed with economical creating employment and incoming. The reactivation for Art &Culture Content Space in Yeongwol will build up social and cultural influences to this region to get a new modern cultural images and improvement of common life of regional people by and large. In the way of the process to globalization, this reactivation project for Art &Culture Content Space in Yeongwol should go on the base of regional culture background as a mean of glocalization paradigm strategically. Ahead of developing model for globalization in macroscopic view point, we have to research the demend of reginal situation of cultural content and build up its own strength points. Because Art & Culture Content Space in Yeongwol is the place of people in Yeongwol directly as itself. And managing plans of reactivation of art & culture content space in Yeongwol should build up with diversity of culture and environmental circumstances.

Background and Aims: Hepatitis B virus (HBV) reactivation was reported to be induced by transcatheter arterial chemoembolization (TACE) in HBV-related hepatocellular carcinonma (HCC) patients with a high incidence. The effective strategy to reduce hepatitis flares due to HBV reactivation in this specific group of patients was limited to lamivudine. This retrospective study was aimed to investigate the efficacy of prophylactic entecavir in HCC patients receiving TACE. Methods: A consecutive series of 191 HBV-related HCC patients receiving TACE were analyzed including 44 patients received prophylactic entecavir. Virologic events, defined as an increase in serum HBV DNA level to more than 1 log10 copies/ml higher than nadir the level, and hepatitis flares due to HBV reactivation were the main endpoints. Results: Patients with or without prophylactic were similar in host factors and the majorities of characteristics regarding to tumor factors, HBV status, liver function and LMR. Notably, cycles of TACE were parallel between the groups. Ten (22.7%) patients receiving prophylactic entecavir reached virologic response. The patients receiving prophylactic entecavir presented significantly reduced virologic events (6.8% vs 54.4%, p=0.000) and hepatitis flares due to HBV reactivation (0.0% vs 11.6%, p=0.039) compared with patients without prophylaxis. Kaplan-Meier analysis illustrated that the patients in the entecavir group presented significantly improved virologic events free survival (p=0.000) and hepatitis flare free survival (p=0.017). Female and Eastern Cooperative Oncology Group (ECOG) performance status 2 was the only significant predictors for virological events in patients without prophylactic antiviral. Rescue antiviral therapy did not reduce the incidence of hepatitis flares due to HBV reactivation. Conclusion: Prophylactic entecavir presented promising efficacy in HBV-related cancer patients receiving TACE. Lower performance status and female gender might be the predictors for HBV reactivation in these patients.

Pseudomonas sp. S-47 is capable of degrading catechol and 4-chlorocatechol via the meta-cleavage pathway. XyITE products catalyze the dioxygenation of the aromatics. The sylT of the strain S-47 is located just upstream of the xylE gene. XylT of the strain S-47 is located just upstream of the xylE gene. XyIT is typical chloroplast-type ferredoxin, which is characterized by 4 cystein residues that are located at positions 41, 46, 49, and 81. The chloroplast-type ferredoxin of Pseudomonas sp. S-47 exhibited a 98% identity with that of P. putida mt-2(TOL plasmid) in the amino acid sequence, but only about a 40 to 60% identity with the corresponding enzymes from other organisms. We constructed two recombinant plasmids (pRES1 containing xylTE and pRES101 containing xylE without xylT) in order to examine the function of XyIT for the reactivation of the catechol 2,3-dioxygenase (XyIE) that is oxidized with hydrogen peroxide was recovered in the catechol 2,3-dioxygenase (C23O) activity about 4 mimutes after incubation, but the pRES101 showed no recovery. That means that the typical chloroplast-type ferredoxin (XyIT) of Pseudomonas sp. S-47 is involved in the reactivation of the oxidized C23O in the dioxygenolytic cleavage of aromatic compounds.

The material deterioration of service-exposed boiler tube steels in fossil power plant was evaluated by using the electrochemical technique namely, modified electrochemical potentiokinetic reactivation(EPR). It was focused that the passivation of Mo$_{6}$C carbide which governs the mechanical properties of Mo alloyed steels did not occur even in the passivity region of steel in sodium molybdate solution and the reactivation peak current (Ip) observed as the result of non-passivation indicating the precipitation of Mo$_{6}$C carbides. To obtain the optimal test conditions for the field test by using the specially designed electrochemical cell, the effects of scan rate, the surface roughness and the pH of electrolyte on Ip value were also investigated. Furthermore, the change of mechanical properties occurred during the long time exposure at high temperature was evlauated quantitatively by small punch(SP) tests and micro hardness test taking account of the metallurgical changes. It is known that reactivation peak current (Ip) has a good relationship with Larson-Miller Parameter(LMP) which represents the information about material deterioration occurred at high temperature environment. In addition it was possible to estimate the ductile-brittle transition temperature (DBTT) by means of the SP test. The Sp test could be, therefore, suggested as a reliable test method for evaluating the material degradation of boiler tube steels. From the good correaltion between the SP DBTT and Ip values shown in this study, it was knows that the change of mechanical properties could be evaluated non-destructively by measurring only Ip values.ues.

Reactivation of human cytomegalovirus (HCMV) from latency is often fatal to immunocompromised individuals. To understand the effect of HCMV on human monocytes where HCMV establishes latency, two human monocyte cell lines at different stages in differentiation, THP-1 and HL-60 were infected with HCMV. While the viability and morphology of HL-60 cells were not significantly affected by HCMV, the viability of THP-1 cells was dramatically decreased by HCMV infection. THP-1 cells infected with HCMV became aggregated and adhered to the surface of culture dishes, probably due to the increased expression of adherence molecules CD11b on the infected THP-1 cells. THP-1 cells established a latent HCMV infection were induced to differentiate by treatment with TPA and hydrocortisone. Recovery of infectious HCMV from the culture supernatant of differentiated THP-1 cells was dependent on the time of induction of differentiation after HCMV infection. Thus, in vitro model of reactivation of HCMV from latently infected monocytes was established.

The first aim of this paper is to investigate and analyze Alan Colquhoun's architectural hermeneutics of tradition, 'conceptual displacement of the past.' The second aim is to overcome the limit of it, and to suggest new architectural hermeneutics of tradition, 'the reactivation of the past.' The architectural work is reduced by Colquhoun to typology or arbitrary language because he believes that without arbitrary language natural language is not able to work effectively. However, he ignores that two languages cannot be separable. When they are separated the key to natural language is understood to be an unverifiable similarity between a sense perception and its correspondence in the architectural object, while the key to arbitrary language becomes mere artificial agreement on the value and function of the linguistic sign. Therefore, natural language is appropriate only when it permits spontaneous combinations of sensory data within complex structures which emerge from, and support, complex human interaction and communication(the shining of the world and of the possibility of creative being in each individual thing). Only when architecture is translated into this kind of language, can it reactivate the world's past, and become poetic.
