Glioblastoma (GBM) remains fatal despite maximal surgical resection, temozolomide chemotherapy, and radiotherapy. Within the GBM microenvironment, tumor-educated microglia and astrocytes adopt immunoregulatory-like STAT3-high and ARG1/TGF-β-high phenotypes, respectively, which shield GBM cells from adaptive immune attack. In this review, we examine emerging adjuvant strategies designed to molecularly reprogram glial cells toward pro-inflammatory C3-high and IFN/NF-κB-high states, amplifying antitumor immunity. First, we summarize key aspects of GBM pathobiology and identify why conventional treatments fail to achieve durable control. Next, we dissect the signaling networks that govern glial phase states, including NF-κB, STAT3, IRF3, NLRP3, and cGAS-STING axes. We then provide a mechanism-centric analysis of pattern-recognition receptor (PRR) agonists, inflammasome modulators, and cyclic-dinucleotide STING agonists, integrating quantitative preclinical data with early clinical trial results. For each adjuvant, we distinguish between direct astrocytic engagement and indirect cytokine-mediated reprogramming.Modulation of glial phase states holds considerable promise for enhancing personalized vaccine efficacy and for converting immunologically “cold” GBM into a T cell-inflamed tumor. Consequently, targeting glial cell phase modulation is a highly attractive strategy for GBM immunotherapy, with the potential to maximize therapeutic benefit. Despite advances in chemo-, radio-, and checkpoint-blockade therapies, the immunosuppressive tumor microenvironment (TME) of GBM and its failure to establish memory immunity limit their impact. Tumor-polarized astrocytes and microglia form a barrier to effective T cell-mediated attack. Emerging evidence shows that redirecting glia toward pro-inflammatory phenotypes can recondition the TME, creating a more permissive landscape for immunotherapy. This review highlights glial phase reprogramming as a promising immunoadjuvant approach, emphasizing molecular circuits, synthetic modulators, and translational prospects.

BACKGROUND: Acinetobacter baumannii infection is a significant health problem worldwide due to increased drug resistance. The limited antimicrobial alternatives for the treatment of severe infections by multidrug-resistant A. baumannii (MDRAB) make the search for other therapeutic options more urgent. Linalool, the major oil compound in Coriandrum sativum, was recently found to have high antibacterial activity against A. baumannii. The purpose of this study was to investigate the synergistic effect of linalool and colistin combinations against MDRAB and extensively drug-resistant A. baumannii (XDRAB). METHODS: A total of 51 strains of A. baumannii clinical isolates, consisting of 10 MDRAB and 41 XDRAB were tested. We determined the minimum inhibitory concentration (MIC) of linalool for the test strains using the broth microdilution method and searched for interactions using the time-kill assay. RESULTS: The time-kill assay showed that the linalool and colistin combination displayed a high rate of synergy (92.1%) (by synergy criteria 2), low rate of indifference (7.8%), and a high rate of bactericidal activity (74.5%) in the 51 clinical isolates of A. baumannii. The synergy rates for the linalool and colistin combination against MDRAB and XDRAB were 96% and 92.1%, respectively. No antagonism was observed for the linalool and colistin combination. CONCLUSION The combination of linalool and colistin showed a high synergy rate, which may be beneficial for controlling MDRAB infections. Therefore, this combination is a good candidate for in vivo studies to assess its efficacy in the treatment of MDRAB infections.

The area of endoscopic application has been continuously expanded since its introduction in the last century and the frequency of its use also increased stiffly in the last decades. Because gastrointestinal endoscopy is naturally exposed to diseased internal organs and contact with pathogenic materials, endoscopy mediated infection or disease transmission becomes a major concern in this field. Gastrointestinal endoscopy is not for single use and the proper reprocessing process is a critical factor for safe and reliable endoscopy procedures. What needed in these circumstances is a practical guideline for reprocessing the endoscope and its accessories which is feasible in the real clinical field to guarantee acceptable prevention of pathogen transmission. This guideline contains principles and instructions of the reprocessing procedure according to the step by step. And it newly includes general information and updated knowledge about endoscopy-mediated infection and disinfection. Multiple societies and working groups participated to revise; Korean Association for the Study of the Liver, the Korean Society of Infectious Diseases, Korean College of Helicobacter and Upper Gastrointestinal Research, the Korean Society of Gastroenterology, Korean Society of Gastrointestinal Cancer, Korean Association for the Study of Intestinal Diseases, Korean Pancreatobiliary Association, the Korean Society of Gastrointestinal Endoscopy Nurses and Associates and Korean Society of Gastrointestinal Endoscopy. Through this cooperation, we enhanced communication and established a better concordance. We still need more researches in this field and fill up the unproven area. And our guidelines will be renewed accordingly.

BACKGROUND/AIMS: Nucleotide-binding oligomerization domain 1 (NOD1) is required for primary intestinal epithelial cells (IECs) to respond to natural mucopeptides secreted by gram-negative bacteria. Infection of human IECs with invasive bacteria up-regulates intercellular adhesion molecule-1 (ICAM-1) expression. However, the role of NOD family members in host defense has been largely unknown. The aim of this study was to determine whether there is a functional role for NOD1 in the up-regulation of ICAM-1 expression in invasive bacteria-infected IECs. METHODS: ICAM-1 mRNA expression was compared between controls, Caco-2 or HT29 cells transfected with an empty vector, and IECs stably transfected with a dominant-negative (DN) NOD1. Expression was compared using qualitative reverse transcription polymerase chain reaction (RT-PCR), real-time RT-PCR, and flow cytometry after infection with enteroinvasive Escherichia coli O29:NM or Shigella flexneri. Nuclear factor kB (NF-κB) activation was determined by electrophoretic mobility shift assays. RESULTS: DN NOD1 significantly inhibited the up-regulation of ICAM-1 expression in response to an enteroinvasive bacterial infection. The Caco-2 cells transfected with DN NOD1 manifested marked inhibition of NF-kB activation in response to E. coli O29:NM infection. CONCLUSIONS Signaling through NOD1 may play an essential role in neutrophil trafficking following infection with enteroinvasive bacteria.

BACKGROUND: Recently, genotypic identification of anaerobes is emerging as an alternative to the phenotypic method. In this study, we evaluated the performance of Vitek 2, API 20A and 16s rRNA gene sequencing for the identification of anaerobic bacteria. METHODS: A total of 35 anaerobe reference strains were identified using Vitek 2, API 20A and 16s rRNA gene sequencing. We evaluated the performance of three methods on the basis of the accurate identification rates. RESULTS: The Vitek 2, API 20A and 16s rRNA gene sequencing identified 54.3, 15.4, and 94.3% of test strains correctly at the species level and identified 77.1, 42.3, and 100% at the genus level, respectively. Results of the McNemar's test showed that there was a significant difference between each of the three identification methods in species level identification (P value<0.05). CONCLUSION: 16s rRNA gene sequencing showed better performance than Vitek 2 or API 20A for anaerobic bacteria. Considering its excellent performance, 16s rRNA gene sequencing may be useful for accurate identification of anaerobic bacteria that cannot be correctly identified by phenotypic methods.

In the field of the forensic medicine, deciding the cause of the injury is very important. Forensic doctors usually use their naked eyes, two dimensional photos, the characteristics and the distribution of the wounds for evaluating the cause of the injuries. After body release, forensic doctors not infrequently met the questions from the law enforcement whether the injuries were matched with the new facts or statements given through the progression of the investigation. In the face of answering this question, the information or evidence about the injury is insufficient. New technologies and instruments are being developed and will be helpful for getting the evidence from the human skin injuries. In this preliminary study, authors try to find the usefulness of appraisal techniques(3D scanner, trace evidence, TMDT, alternative light) that are already used for other purposes in forensic field. These techniques have their own merits for preserving the evidences from the injured skin. But further studies and systemic approaches are essential for more scientifically verified evaluation of the cause of the skin injury.

The clinical application of the three-dimensional radiographic technique had been limited to standard Broadbent-Bolton cephalometer with biplanar stereoradiography. We developed a new method for compensating the error of head position in ordinary non-biplanar cephalostat. It became to possible to use the three dimensional cephalogram commonly in clinical bases. 1. The method of methemetical compensation of head positioning error in non-biplanar condition was evaluated with dry skull. The error of the method of first and the second trial was 0.46+/-1.21, 0.33+/-0.90mm, which means the error of the head positioning correction in conventional cephalogram was within clinical acceptance. 2. The reproducibility of this system for clinical application was 0.54 mm (-2.99~2.26mm) which defines the absolute mean difference of the first and second trial. Compare to the The landmark identification error 1.2+/-1.6mm, the error of the measurement was within the range of landmark identification error. The result indicates the adequate clinical accuracy of the computation of three-dimensional coordinates by compensation of the error of the head position in ordinary non-biplanar cephalostat.

Complement-mediated neutrophil activation has been hypothesized to be an important mechanism of reperfusion injury. It has been proposed that C1 esterase inhibitor (C1 INH) may prevent the complement-dependent activation of polymorphonuclear leukocytes (PMNs) that occurs within postischemic myocardium. Therefore, The effect of C1 INH was examined in neutrophil dependent isolated perfused rat heart model of ischemia (I) (20 min) and reperfusion (R) (45 min). Administration of C1 INH (5 mg/Kg) to I/R hearts in the presence of PMNs (100 X 106) and homologous plasma improved coronary flow and preserved cardiac contractile function (p<0.001) in comparison to those I/R hearts receiving only vehicle. In addition, C1 INH significantly (p<0.001) reduced PMN accumulation in the ischemic myocardium as evidenced by an attenuation in myeloperoxidase activity. These findings demonstrate the C1 INH is a potent and effective cardioprotective agent inhibits leukocyte-endothelial interaction and preserves cardiac contractile function and coronary perfusion following myocardial ischemia and reperfusion.

Hepatitis B virus(HBV) infection has been suggested as the etiologic agent in membranoproliferative glomerulonephritis(MPGN), but the mechanism by which HBV infection leads to MPGN in human has not been established. To localize the HBV antigen and HBV-DNA in the kidney tissue, we examined paraffin sections of kidney biopsies which were positive for HBsAg by immunohistochemical study from 13 HBV carriers with MPGN (HBV-MPGN). Polymerase chain reaction(PCR) and in situ PCR(ISP) were used for the HBV DNA amplification and localization in kidney tissues. Primers used in PCR and ISP were from the S, C, and X HBV-DNA regions. Immunohistochemical study showed HBsAg deposits on the mesangium and glomerular capillaries. Arteriolar deposits were also occasionally observed. PCR for the S, C, and X regions were positive in 11 patients(85%), 11 patients(85%), and 9 patients (69%), respectively. The PCR findings were further confirmed by direct sequencing of PCR products and the amplification of HSP70 gene as a control. ISP showed the amplified HBV-DNA at the glomeruli and renal tubules. For S region, ISP was positive in 7 patients. For C and X regions, ISP was positive in 8 patients, respectively. 5 patients showed the positive signals for both the glomeruli and tubules, while 4 patients were positive at the tubules only. These 4 patients seemed to have the longer disease durations when compared to the other 5 patients (52.8 months vs. 11.8 months), but it was not statistically significant. In conclusion, the detection and the localization of HBV antigen and DNA in renal tissues indicate the presence of the complete virion in the kidney. These results suggest that HBV may infect the kidneys of HBV carriers with MPGN.
