Abstract
Mesenchymal stem/stromal cells (MSCs) are an attractive platform for cell therapy due to their safety profile and unique ability to secrete broad arrays of immunomodulatory and regenerative molecules. Yet, MSCs are well known to require preconditioning or priming to boost their therapeutic efficacy. Current priming methods offer limited control over MSC activation, yield transient effects, and often induce expression of pro-inflammatory effectors that can potentiate immunogenicity. Here, we describe a 'genetic priming' method that can both selectively and sustainably boost MSC potency via the controlled expression of the inflammatory-stimulus-responsive transcription factor IRF1 (interferon response factor 1). MSCs engineered to hyper-express IRF1 recapitulate many core responses that are accessed by biochemical priming using the proinflammatory cytokine interferon-γ (IFNγ). This includes the upregulation of anti-inflammatory effector molecules and the potentiation of MSC capacities to suppress T cell activation. However, we show that IRF1-mediated genetic priming is much more persistent than biochemical priming and can circumvent IFNγ-dependent expression of immunogenic MHC class II molecules. Together, the ability to sustainably activate and selectively tailor MSC priming responses creates the possibility of programming MSC activation more comprehensively for therapeutic applications.

Abstract
BACKGROUND A large epidemic, such as that observed with SARS-CoV-2, seriously challenges available hospital capacity, and this would be augmented by infection of healthcare workers (HCW). Bacillus Calmette-Guérin (BCG) is a vaccine against tuberculosis, with protective non-specific effects against other respiratory tract infections in vitro and in vivo. Preliminary analyses suggest that regions of the world with existing BCG vaccination programs have lower incidence and mortality from COVID-19. We hypothesize that BCG vaccination can reduce SARS-CoV-2 infection and disease severity. METHODS This will be a placebo-controlled adaptive multi-center randomized controlled trial. A total of 1800 individuals considered to be at high risk, including those with comorbidities (hypertension, diabetes, obesity, reactive airway disease, smokers), racial and ethnic minorities, elderly, teachers, police, restaurant wait-staff, delivery personnel, health care workers who are defined as personnel working in a healthcare setting, at a hospital, medical center or clinic (veterinary, dental, ophthalmology), and first responders (paramedics, firefighters, or law enforcement), will be randomly assigned to two treatment groups. The treatment groups will receive intradermal administration of BCG vaccine or placebo (saline) with groups at a 1:1 ratio. Individuals will be tracked for evidence of SARS-CoV-2 infection and severity as well as obtaining whole blood to track immunological markers, and a sub-study will include cognitive function and brain imaging. The majority of individuals will be followed for 6 months, with an option to extend for another 6 months, and the cognitive sub-study duration is 2 years. We will plot Kaplan-Meier curves that will be plotted comparing groups and hazard ratios and p-values reported using Cox proportional hazard models. DISCUSSION It is expected this trial will allow evaluation of the effects of BCG vaccination at a population level in high-risk healthcare individuals through a mitigated clinical course of SARS-CoV-2 infection and inform policy making during the ongoing epidemic. TRIAL REGISTRATION ClinicalTrials.gov NCT04348370. Registered on April 16, 2020.

Abstract
BACKGROUND Epidermolytic ichthyosis (EI) is a major form of nonsyndromic inherited ichthyosis, characterized by erythroderma, marked hyperkeratosis and scale, bulla and erosion at birth, associated with KRT1/KRT10 mutations. The cytokine and chemokine profiles in EI are poorly understood, and specific treatment options have not been established. AIM To explore novel biomarkers and therapeutic targets in patients with EI. METHODS We analysed cytokine levels in serum and skin samples from 10 patients with inherited ichthyosis, including seven patients with EI. Wild-type and mutant KRT1 constructs were established and transfected into HaCaT cells, an immortalized keratinocyte cell line, for in vitro immunoblotting and immunocytochemistry analyses. RESULTS Multiplex cytokine/chemokine analysis revealed that 10 cytokines/chemokines [interleukin (IL)-1β, IL-4, IL-17A, IL-16, IL-18, IL-1 receptor-α, macrophage colony-stimulating factor, interferon-α2, basic fibroblast growth factor and monocyte chemotactic protein-3] were significantly increased in patients with EI. Furthermore, IL-18 levels were significantly higher in patients with EI [n = 7; 2714.1 (1438.0) pg mL-1] than in healthy controls [n = 11; 218.4 (28.4) pg mL-1, P < 0.01]. Immunohistochemical analyses showed that IL-18 expression was elevated in skin samples from patients with EI. Serum IL-18 levels correlated with the severity of ichthyosis, as measured by the Ichthyosis Scoring System. Immunoblotting analysis revealed that mature IL-18 levels were increased in the supernatant of mutant KRT1 expressing HaCaT cells. Additionally, these cells showed NLRP3 aggregation in the cytoplasm and ASC clustered around mutant keratin aggregations. These findings suggest that mutant keratin might promote the activation of the NLRP3 inflammasome and its downstream caspase-1-mediated IL-18 release in keratinocytes from patients with EI. CONCLUSIONS Our results suggest that serum IL-18 is a severity marker released from the skin of patients with EI. Blockade of IL-18 may be a useful novel therapeutic option for patients with EI.

Abstract
Abstract
Background
Severe and chronic infections, such as sepsis and Tuberculosis, result in macrophage immune tolerance in order to prevent pathologic inflammation. Immune tolerance is believed to be a result of metabolic dysregulation, especially of the TCA cycle. Metabolites play a critical role in regulating epigenetic mechanism, but many aspects remain poorly understood.
Methods
An in-vitro LPS tolerance model was used to evaluate if manipulating the TCA cycle could mitigate immune tolerance. Intracellular signaling, DNA methylation, and nuclear localization were measured using RPPA, Illumina EPIC, and confocal microscopy, respectively.
Results
Metabolic inhibitors of glycolysis (metformin), the TCA cycle (BAY 1436032), and mTOR (rapamycin and everolimus) blocked LPS-induced immune tolerance. LPS treatment changed the methylome with hypermethylation of key genes of the TCA cycle including PDP2, NDUFS8, TRAP1 and PDK2 and lead to increased nuclear localization of the TCA enzymes, which could be ameliorated with inhibitors. Increased levels of key mediators of the TCA by LPS treatment including p-mTOR, pAKT, LDHA, IDH1, LC3A and epigenetic regulator p300 was significantly downregulated by pre-treatment with metformin, everolimus and BAY 1436032. BAY 1436032 also significantly reduced the LPS induced upregulation of epigenetic enzymes including histone deacetylases (HDAC) 3,4, and EZH2.
Conclusion
Previous studies demonstrated that LPS induces epigenetic-mediated immune tolerance. Here we show this can be mitigated by inhibiting glycolysis, mTOR pathway and TCA cycle. This could have clinical implications in treatment of sepsis and Tuberculosis among other diseases.

Abstract
Background: Tuberculosis (TB) is the archetypical chronic infection, with patients having months of symptoms before diagnosis. In the two years after successful therapy, survivors of TB have a three-fold increased risk of death. Methods: Guinea pigs were infected with Mycobacterium tuberculosis (Mtb) for 45 days, followed by RRBS DNA methylation analysis. In humans, network analysis of differentially expressed genes across three TB cohorts were visualized at the pathway-level. Serum levels of inflammation were measured by ELISA. Horvath (DNA methylation) and RNA-seq biological clocks were used to investigate shifts in chronological age among humans with TB. Results: Guinea pigs with TB demonstrated DNA hypermethylation and showed system-level similarity to humans with TB (p-value = 0.002). The transcriptome in TB in multiple cohorts was enriched for DNA methylation and cellular senescence. Senescence associated proteins CXCL9, CXCL10, and TNF were elevated in TB patients compared to healthy controls. Humans with TB demonstrate 12.7 years (95% CI: 7.5, 21.9) and 14.38 years (95% CI: 10.23–18.53) of cellular aging as measured by epigenetic and gene expression based cellular clocks, respectively. Conclusions: In both guinea pigs and humans, TB perturbs epigenetic processes, promoting premature cellular aging and inflammation, a plausible means to explain the long-term detrimental health outcomes after TB.

Abstract
BACKGROUND In vitro, animal model, and clinical evidence suggests that tuberculosis is not a monomorphic disease, and that host response to tuberculosis is protean with multiple distinct molecular pathways and pathologies (endotypes). We applied unbiased clustering to identify separate tuberculosis endotypes with classifiable gene expression patterns and clinical outcomes. METHODS A cohort comprised of microarray gene expression data from microbiologically confirmed tuberculosis patients were used to identify putative endotypes. One microarray cohort with longitudinal clinical outcomes was reserved for validation, as was two RNA-seq cohorts. Finally, a separate cohort of tuberculosis patients with functional immune responses was evaluated to clarify stimulated from unstimulated immune responses. RESULTS A discovery cohort, including 435 tuberculosis patients and 533 asymptomatic controls, identified two tuberculosis endotypes. Endotype A is characterised by increased expression of genes related to inflammation and immunity and decreased metabolism and proliferation; in contrast, endotype B has increased activity of metabolism and proliferation pathways. An independent RNA-seq validation cohort, including 118 tuberculosis patients and 179 controls, validated the discovery results. Gene expression signatures for treatment failure were elevated in endotype A in the discovery cohort, and a separate validation cohort confirmed that endotype A patients had slower time to culture conversion, and a reduced cure rate. These observations suggest that endotypes reflect functional immunity, supported by the observation that tuberculosis patients with a hyperinflammatory endotype have less responsive cytokine production upon stimulation. CONCLUSION These findings provide evidence that metabolic and immune profiling could inform optimisation of endotype-specific host-directed therapies for tuberculosis.

Abstract
The immune response must balance the pro-inflammatory, cell-mediated cytotoxicity with the anti-inflammatory and wound repair response. Epigenetic mechanisms mediate this balance and limit host immunity from inducing exuberant collateral damage to host tissue after severe and chronic infections. However, following treatment for these infections, including sepsis, pneumonia, hepatitis B, hepatitis C, HIV, tuberculosis (TB) or schistosomiasis, detrimental epigenetic scars persist, and result in long-lasting immune suppression. This is hypothesized to be one of the contributing mechanisms explaining why survivors of infection have increased all-cause mortality and increased rates of unrelated secondary infections. The mechanisms that induce epigenetic-mediated immune suppression have been demonstrated in-vitro and in animal models. Modulation of the AMP-activated protein kinase (AMPK)-mammalian target of rapamycin (mTOR), nuclear factor of activated T cells (NFAT) or nuclear receptor (NR4A) pathways is able to block or reverse the development of detrimental epigenetic scars. Similarly, drugs that directly modify epigenetic enzymes, such as those that inhibit histone deacetylases (HDAC) inhibitors, DNA hypomethylating agents or modifiers of the Nucleosome Remodeling and DNA methylation (NuRD) complex or Polycomb Repressive Complex (PRC) have demonstrated capacity to restore host immunity in the setting of cancer-, LCMV- or murine sepsis-induced epigenetic-mediated immune suppression. A third clinically feasible strategy for reversing detrimental epigenetic scars includes bioengineering approaches to either directly reverse the detrimental epigenetic marks or to modify the epigenetic enzymes or transcription factors that induce detrimental epigenetic scars. Each of these approaches, alone or in combination, have ablated or reversed detrimental epigenetic marks in in-vitro or in animal models; translational studies are now required to evaluate clinical applicability.

Abstract
There is hope that host-directed therapy (HDT) for Tuberculosis (TB) can either shorten treatment duration, help cure drug resistant disease or limit the immunopathology. Many candidate HDT drugs have been proposed, however solid evidence only exists for a few select patient groups. The clinical presentation of TB is variable, with differences in severity, tissue pathology, and bacillary burden. TB clinical phenotypes likely determine the potential benefit of HDT. Underlying TB clinical phenotypes, there are TB "endotypes," defined as distinct molecular profiles, with specific metabolic, epigenetic, transcriptional, and immune phenotypes. TB endotypes can be characterized by either immunodeficiency or pathologic excessive inflammation. Additional factors, like comorbidities (HIV, diabetes, helminth infection), structural lung disease or Mycobacterial virulence also drive TB endotypes. Precise disease phenotyping, combined with in-depth immunologic and molecular profiling and multimodal omics integration, can identify TB endotypes, guide endotype-specific HDT, and improve TB outcomes, similar to advances in cancer medicine.

Abstract
The development of disseminated cryptococcosis has historically occurred in patients living with advanced human immunodeficiency virus or other immunosuppressive conditions affecting T-cell function. Recently, patients with anti-cytokine neutralising autoantibodies have been recognised to be at risk for disseminated infections by opportunistic intracellular pathogens, including Cryptococcus species. Herein, we present a previously healthy 26-year-old man who was evaluated with disseminated cryptococcosis involving the bone, lung, mediastinum and brain. The patient's serum cryptococcal antigen titres were >1:1,100,000, and evaluation for an underlying immunodeficiency revealed high titres for anti-granulocyte-macrophage colony-stimulating factor (GM-CSF) autoantibodies. We also review the literature of all published cases of disseminated cryptococcosis associated with the presence of anti-GM-CSF autoantibodies. Clinicians should have a heightened awareness of anti-cytokine autoantibodies in patients without a known immunodeficiency and development disseminated infections by opportunistic intracellular pathogens.

Abstract
Tuberculosis is a bacterial infectious disease that is mainly transmitted from human to human via infectious aerosols. Currently, tuberculosis is the leading cause of death by an infectious disease world-wide. In the past decade, the number of patients affected by tuberculosis has increased by ~20 percent and the emergence of drug-resistant strains of Mycobacterium tuberculosis challenges the goal of elimination of tuberculosis in the near future. For the last 50 years, management of patients with tuberculosis has followed a standardized management approach. This standardization neglects the variation in human susceptibility to infection, immune response, the pharmacokinetics of drugs, and the individual duration of treatment needed to achieve relapse-free cure. Here we propose a package of precision medicine-guided therapies that has the prospect to drive clinical management decisions, based on both host immunity and M. tuberculosis strains genetics. Recently, important scientific discoveries and technological advances have been achieved that provide a perspective for individualized rather than standardized management of patients with tuberculosis. For the individual selection of best medicines and host-directed therapies, personalized drug dosing, and treatment durations, physicians treating patients with tuberculosis will be able to rely on these advances in systems biology and to apply them at the bedside.

Abstract
G protein-coupled receptors (GPCRs) transduce extracellular signals into cells by interacting with G proteins and arrestins. Emerging evidence suggests that GPCRs on the plasma membrane are in a dynamic equilibrium among monomers, dimers, and larger oligomers. Nevertheless, the role of the oligomer formation in the GPCR signal transduction remains unclear. Using multicolor single-molecule live-cell imaging, we show a dynamic interconversion between small and large oligomer states of a chemoattractant GPCR, Formyl Peptide Receptor 1 (FPR1), and its binding affinity with G protein. Full agonist stimulation increased a fraction of large FPR1 oligomers, which allowed for prolonged FPR1-G protein interaction. The G protein interaction with FPR1 was most stabilized at the full agonist-bound large FPR1 oligomers. Based on these results, we propose that G protein-mediated signal transduction may be regulated synergistically by the ligand-binding and FPR1 oligomerization. Cooperative signal control induced by receptor oligomerization is anticipated as a target for drug discovery.

Abstract
Mycobacterium tuberculosis (M. tuberculosis) has coevolved with humans for millennia and developed multiple mechanisms to evade host immunity. Restoring host immunity in order to improve outcomes and potentially shorten existing therapy will require identification of the full complement by which host immunity is inhibited. Perturbation of host DNA methylation is a mechanism induced by chronic infections such as HIV, HPV, lymphocytic choriomeningitis virus (LCMV), and schistosomiasis to evade host immunity. Here, we evaluated the DNA methylation status of patients with tuberculosis (TB) and their asymptomatic household contacts and found that the patients with TB have DNA hypermethylation of the IL-2/STAT5, TNF/NF-κB, and IFN-γ signaling pathways. We performed methylation-sensitive restriction enzyme-quantitative PCR (MSRE-qPCR) and observed that multiple genes of the IL-12/IFN-γ signaling pathway (IL12B, IL12RB2, TYK2, IFNGR1, JAK1, and JAK2) were hypermethylated in patients with TB. The DNA hypermethylation of these pathways was associated with decreased immune responsiveness with decreased mitogen-induced upregulation of IFN-γ, TNF, IL-6, CXCL9, CXCL10, and IL-1β production. The DNA hypermethylation of the IL-12/IFN-γ pathway was associated with decreased IFN-γ-induced gene expression and decreased IL-12-inducible upregulation of IFN-γ. This study demonstrates that immune cells from patients with TB are characterized by DNA hypermethylation of genes critical to mycobacterial immunity resulting in decreased mycobacteria-specific and nonspecific immune responsiveness.

Abstract
Abstract
BACKGROUND
Less than 10% of individuals infected with Mtb develop disease. Similarly, in the pre-antibiotic era, ~20% of Tuberculosis (TB) patients overcame the disease. This implies host immunity can control Mtb infection. We evaluated the role of cytotoxic immune cells (CD8, CD56 and CD3+CD56+) among individuals with chronic infections that increase risk of TB progression.
METHODS
DNA Methyl EPIC was evaluated in patients with helminths, HIV and TB (n = 32) and flow-based immune phenotyping was implemented on 108 individuals. Gene expression of 717 TB patients and 525 healthy controls was downloaded from publicly available databases.
RESULTS
All evaluated cytotoxic cells displayed DNA methylation perturbations in the IL-2-STAT5, PI3K and IFNγ signaling pathways. TB patients experienced DNA hyper-methylation of perforin in CD56 NK cells and in granzyme A and granzyme B of CD8+ cytotoxic lymphocytes (CTLs). By flow cytometry TB patients up-regulated mycobacterial-specific perforin in CTLs while CD3−CD56+ NK cells expressed decreased perforin. Early evidence suggests that the increased perforin expression from CTLs was heterogenous and only occurs in ~46% of TB patients. Further evidence for heterogenous TB sub-groups was demonstrated by gene expression as 333 TB patients had increased perforin gene expression, while 313 had decreased gene expression (log2 fold change with FDR < 1%).
CONCLUSION
To evaluate the DNA methylation-immune phenotype associations from this clinical cohort, mechanistic studies manipulating DNA methylation status are undergoing. Identifying how epigenetic modifications alter cytotoxic cells capacity to kill intracellular mycobacteria is critical to future host directed therapeutic options.

Abstract
Abstract
In the pre-antibiotic era, ~20% of Tuberculosis (TB) patients overcame the disease without therapy, implying host immunity can sometimes control disease. The risk of disease progression is higher among HIV-infected individuals and children, therefore we evaluate how HIV and age alter the balance of cytotoxic versus immune regulatory NKT immune phenotype in individuals with TB and latent Mycobacterium tuberculosis infection (LTBi). We evaluated the NKT immune response from 49 individuals with TB (25 HIV-infected) and 48 with asymptomatic LTBi (14 HIV-infected). Using flow cytometry based multi-dimensional immune profiling, we analyzed the expression level of previously described determinants of NKT cytotoxicity (CD3dim) and immune regulatory (CD3bright) phenotype and function. CD3bright NKT cell population was correlated with age during children TB (p = 0.002). This cell type had increased in adults with TB (p = 0.034), but not in children. Also, high level of perforin producing CD3bright NKT cells had increased in adults with TB compare to adults with LTBi (p = 0.004). On the other hand, CD3dim NKT cell had no age correlation nor difference between TB and LTBi participants. While HIV-infected LTBi individuals had decreased perforin production in CD3dim NKT cells (p = 0.012). CD3bright and CD3dim NKT sub-populations previously reported influence regulatory versus cytotoxic function. We demonstrate that age and HIV status of participants have effected to regulatory and cytotoxic function, respectively. This suggested that these two factors have different mechanisms, decreasing perforin high producing CD3bright NKT cells and decreasing perforin production in CD3dim NKT, which promote TB disease progression.

Abstract
Abstract
BACKGROUND
Chronic antigen stimulation from HIV, HPV, LCMV and schistosomiasis induce epigenetic-mediated immune exhaustion. Individuals with successful anti-TB therapy (ATT) have a thirteen-fold increased risk of developing recurrent TB.
METHODS
From a cohort of HIV infected and uninfected individuals with TB and their asymptomatic household contacts (n=32), genome-wide DNA methylation (DNA MethylEPIC) and epigenetic deconvolution (EDEC) identified cell-specific DNA methylation. Cell-specific results were validated with MSRE-PCR, gene expression and flow cytometry-based Mtb-specific multi-dimensional immune profiling.
RESULTS
Participants with TB had DNA hypermethylation in the IL-2, TCR and IFN-γ signalling pathways. The IFN-γ signalling pathway was affected in both innate (NK cells and monocytes) as well as adaptive (CD4 and CD8 T cells) lineages. Select DNA hyper-methylated differences were validated using MSRE-PCR. Pioneer and Transcription factors critical for cell-mediated immunity were also significantly differentially methylated with enrichment scores compatible with previous epigenetic-mediated immune exhaustion. After overnight stimulation with IFN-γ, TB patients have decreased IFN-γ-inducible gene expression. Six months after the completion of successful ATT, participants with TB have persistent DNA hypermethylation.
DISCUSSION
Persistent DNA hypermethylation may be a potential mechanism by which individuals with TB are at increased risk of recurrent disease. This may also assist in identifying potential new targets for host-directed therapy.

Abstract
Epigenetic mechanisms, such as DNA methylation, determine immune cell phenotype. To understand the epigenetic alterations induced by helminth coinfections, we evaluated the longitudinal effect of ascariasis and schistosomiasis infection on CD4+ T cell DNA methylation and the downstream tuberculosis (TB)-specific and bacillus Calmette-Guérin-induced immune phenotype. All experiments were performed on human primary immune cells from a longitudinal cohort of recently TB-exposed children. Compared with age-matched uninfected controls, children with active Schistosoma haematobium and Ascaris lumbricoides infection had 751 differentially DNA-methylated genes, with 72% hypermethylated. Gene ontology pathway analysis identified inhibition of IFN-γ signaling, cellular proliferation, and the Th1 pathway. Targeted real-time quantitative PCR after methyl-specific endonuclease digestion confirmed DNA hypermethylation of the transcription factors BATF3, ID2, STAT5A, IRF5, PPARg, RUNX2, IRF4, and NFATC1 and cytokines or cytokine receptors IFNGR1, TNFS11, RELT (TNF receptor), IL12RB2, and IL12B (p < 0.001; Sidak-Bonferroni). Functional blockage of the IFN-γ signaling pathway was confirmed, with helminth-infected individuals having decreased upregulation of IFN-γ-inducible genes (Mann-Whitney p < 0.05). Hypomethylation of the IL-4 pathway and DNA hypermethylation of the Th1 pathway was confirmed by Ag-specific multidimensional flow cytometry demonstrating decreased TB-specific IFN-γ and TNF and increased IL-4 production by CD4+ T cells (Wilcoxon signed-rank p < 0.05). In S. haematobium-infected individuals, these DNA methylation and immune phenotypic changes persisted at least 6 mo after successful deworming. This work demonstrates that helminth infection induces DNA methylation and immune perturbations that inhibit TB-specific immune control and that the duration of these changes are helminth specific.

Abstract
BACKGROUND Endogenous circadian oscillators distributed across the mammalian body are synchronised among themselves and with external time via a variety of signalling molecules, some of which interact with G-protein-coupled receptors (GPCRs). GPCRs can regulate cell physiology via pathways originating with heterotrimeric G-proteins or β-arrestins. We applied an optogenetic approach to determine the contribution of these two signalling modes on circadian phase. RESULTS We employed a photopigment (JellyOp) that activates Gαs signalling with better selectivity and higher sensitivity than available alternatives, and a point mutant of this pigment (F112A) biased towards β-arrestin signalling. When expressed in fibroblasts, both native JellyOp and the F112A arrestin-biased mutant drove light-dependent phase resetting in the circadian clock. Shifts induced by the two opsins differed in their circadian phase dependence and the degree to which they were associated with clock gene induction. CONCLUSIONS Our data imply separable G-protein and arrestin inputs to the mammalian circadian clock and establish a pair of optogenetic tools suitable for manipulating Gαs- and β-arrestin-biased signalling in live cells.

Abstract
Enzymatically prepared alginate oligomer (AO) promoted the growth of Chlamydomonas reinhardtii in a concentration-dependent manner. AO at 2.5 mg/mL induced increase in expression levels of cyclin A, cyclin B, and cyclin D in C. reinhardtii. CuSO4 at 100 μM suppressed the growth of C. reinhardtiin, and AO at 2.5 mg/mL significantly alleviated the toxicity of CuSO4. Increased intracellular reactive oxygen species level in C. reinhardtii induced by CuSO4 was reduced by AO. After cultivation with CuSO4 at 100 μM, expression levels of ascorbate peroxidase and superoxide dismutase in C. reinhardtii were increased, and AO reduced the increased levels of these enzymes. These results suggest that AO exhibits beneficial effects on C. reinhardtii through influencing the expression of various genes not only at normal growth condition but also under CuSO4 stress.

Abstract
A harmful dinoflagellate, Heterocapsa circularisquama, is highly toxic to shellfish and the zooplankton rotifer Brachionus plicatilis. A previous study found that H. circularisquama has both light-dependent and -independent haemolytic agents, which might be responsible for its toxicity. Detailed analysis of the haemolytic activity of H. circularisquama suggested that light-independent haemolytic activity was mediated mainly through intact cells, whereas light-dependent haemolytic activity was mediated by intracellular agents which can be discharged from ruptured cells. Because H. circularisquama showed similar toxicity to rotifers regardless of the light conditions, and because ultrasonic ruptured H. circularisquama cells showed no significant toxicity to rotifers, it was suggested that live cell-mediated light-independent haemolytic activity is a major factor responsible for the observed toxicity to rotifers. Interestingly, the ultrasonic-ruptured cells of H. circularisquama suppressed their own lethal effect on the rotifers. Analysis of samples of the cell contents (supernatant) and cell fragments (precipitate) prepared from the ruptured H. circularisquama cells indicated that the cell contents contain inhibitors for the light-independent cell-mediated haemolytic activity, toxins affecting H. circularisquama cells themselves, as well as light-dependent haemolytic agents. Ethanol extract prepared from H. circularisquama, which is supposed to contain a porphyrin derivative that displays photosensitising haemolytic activity, showed potent toxicity to Chattonella marina, Chattonella antiqua, and Karenia mikimotoi, as well as to H. circularisquama at the concentration range at which no significant toxicity to rotifers was observed. Analysis on a column of Sephadex LH-20 revealed that light-dependent haemolytic activity and inhibitory activity on cell-mediated light-independent haemolytic activity existed in two separate fractions (f-2 and f-3), suggesting that both activities might be derived from common compounds. Our results suggest that the photosensitising haemolytic toxin discharged from ruptured H. circularisquama cells has a relatively broad spectrum of phytoplankton toxicity, and that physical collapse of H. circularisquama cells can lead not only to the disappearance of its own toxicity, but also to mitigation of the effects of other HABs.

Abstract
Mortality associated with Staphylococcus aureus infection remains high during the sub-acute phase of burn injury. In this study, we aimed to improve antibacterial resistance of sub-acutely burned mice through macrophage polarization. Sepsis did not develop in mice at the sub-acute phase of 5% total body surface area (TBSA) burn after being infected with methicillin-resistant S. aureus (MRSA), and M1 macrophages (interleukin (IL)-10-IL-12+ inducible nitric oxide synthase+ Mφ) were isolated from these mice. In contrast, predominantly M2b macrophages (C-C motif chemokine ligand 1 (CCL1)+IL-10+IL-12- Mφ) were isolated from mice with >15% TBSA burn, and all of these mice died after the same MRSA infection. Comparing NOD scid gamma mice inoculated with Mφ with 25% TBSA burns, all mice treated with CCL1 antisense oligodeoxynucleotide (ODN) survived after MRSA infection, whereas all untreated mice given the same infection died within 4 days. CCL1 antisense ODN has been characterized as a specific polarizer of M2bMφ. M1Mφ were isolated from MRSA-infected mice with 25% TBSA burn after treatment with CCL1 antisense ODN, and these mice were shown to be resistant against a lethal dose of MRSA infection. M1Mφ were also isolated from 25% TBSA-burned mice infected with MRSA when the ODN was administered therapeutically, and subsequent sepsis was effectively controlled in these mice. These results indicate that the M2bMφ polarizer is beneficial for controlling MRSA infection in mice at the sub-acute phase of severe burn injury.

Abstract
M2b macrophages (Mφ) play a major role in the increased susceptibility of subacutely burned patients, to sepsis stemming from enterococcal translocation. Certain opportunistic infections in severely burned mice have been controlled by murine CCL1 antisense oligodeoxynucleotide (ODN), a specific polarizer of mouse M2bMφ. In the present study, we have screened CCL1 antisense ODN, which is active against human M2bMφ. Among the 20 CCL1 antisense ODNs synthesized in our laboratory, HCA-11 was shown to be the most active polarizer for human CCL1+CD163+CD14+ cells. Burn patient CCL1+CD163+CD14+ cells (3 × 105 cells/mL) switched to quiescent CCL1-CD163-CD14+ cells within 48 h in cultures supplemented with 100 μg/mL of HCA-11. After treatment with a 25 μg/chimera dose of HCA-11, the bacterial growth was not observed in various organs of patient chimeras (γNSG mice inoculated with burn patient WBCs) infected with a lethal dose of Methicillin-resistant Staphylococcus aureus. The host antibacterial defenses against certain opportunistic pathogens should be improved in severely burned patients treated with a human CCL1 antisense ODN, HCA-11.

Abstract
We treated 7 cases of dural arteriovenous fistulas (dAVF) with isolated sinus by transvenous direct embolization. The fistulas located in the transverse-sigmoid sinus in 5 cases, superior sagittal sinus in 1 case and transverse-sigmoid and superior sagittal sinus in 1 case. The initial symptoms were generalized convulsion in 2 cases, disturbed consciousness in 1 case, tinnitus in 2 cases and transient ischemic attack in 2 cases. We performed sinus packing with coils in all cases following transarterial embolization. All patients improved neurologically after the treatments and AVFs completely disappeared in all cases.

Abstract
Chattonella antiqua isolated in 2010 showed extremely more potent fish-killing activities against red sea bream, Japanese horse mackerel, and blue damselfish than those of Chattonella marina isolated in 1985. Chemiluminescence and electron spin resonance (ESR) analyses suggested greater reactive oxygen species (ROS)-producing activity of C. antiqua than that of C. marina. Sodium benzoate, a hydroxyl radical scavenger, significantly suppressed the fish-killing activity of C. antiqua on blue damselfish. The chlorophyll level in the gill tissue of blue damselfish exposed to flagellate cells increased along with the exposure time, and the cell count of gill-associated C. antiqua estimated with chlorophyll level was higher than that of C. marina. These results suggest that the ROS-producing activity and affinity of Chattonella cells to the gill surface may be important factors influencing the fish-killing activity of Chattonella species.

Abstract
Chronic alcohol consumption markedly impairs host antibacterial defense against opportunistic infections. γ-irradiated NOD-SCID IL-2Rγ(null) mice inoculated with nonalcoholic PBMCs (control PBMC chimeras) resisted Klebsiella pneumonia and gut bacteria-associated sepsis, whereas the chimeras created with alcoholic PBMCs (alcoholic PBMC chimeras) were very susceptible to these infections. M1 monocytes (IL-12(+)IL-10(-)CD163(-)CD14(+) cells), major effector cells in antibacterial innate immunity, were not induced by a bacterial Ag in alcoholic PBMC cultures, and M2b monocytes (CCL1(+)CD163(+)CD14(+) cells), which predominated in alcoholic PBMCs, were shown to be inhibitor cells on the Ag-stimulated monocyte conversion from quiescent monocytes to M1 monocytes. CCL1, which functions to maintain M2b macrophage properties, was produced by M2b monocytes isolated from alcoholic PBMCs. These M2b monocytes reverted to quiescent monocytes (IL-12(-)IL-10(-)CCL1(-)CD163(-)CD14(+) cells) in cultures supplemented with CCL1 antisense oligodeoxynucleotide, and the subsequent quiescent monocytes easily converted to M1 monocytes under bacterial Ag stimulation. Alcoholic PBMC chimeras treated with CCL1 antisense oligodeoxynucleotide were resistant against pulmonary infection by K. pneumoniae and sepsis stemming from enterococcal translocation. These results indicate that a majority of monocytes polarize to an M2b phenotype in association with alcohol abuse, and this polarization contributes to the increased susceptibility of alcoholics to gut and lung infections. Bacterial pneumonia and gut bacteria-associated sepsis, frequently seen in alcoholics, can be controlled through the polarization of macrophage phenotypes.

Abstract
Luciferase, a bioluminescent protein, has been used as an analytical tool to visualize intracellular phenomena. Luciferase with red light emission is particularly useful for bioluminescence imaging because of its high transmittance in mammalian tissues. However, the luminescence intensity of existing luciferases with their emission over 600 nm is insufficient for imaging studies because of their weak intensities. We developed mutants of Emerald luciferase (Eluc) from Brazilian click beetle (Pyrearinus termitilluminans), which emits the strongest bioluminescence among beetle luciferases. We successively introduced four amino acid mutations into the luciferase based on a predicted structure of Eluc using homology modeling. Results showed that quadruple mutations R214K/H241K/S246H/H347A into the beetle luciferase emit luminescence with emission maximum at 626 nm, 88-nm red-shift from the wild-type luciferase. This mutant luciferase is anticipated for application in in vivo multicolor imaging in living samples.

Abstract
Gut bacteria-associated sepsis is a serious concern in persons who have radiation-induced injuries in the gastrointestinal system. Such infection does not normally occur in healthy hosts with M1Mϕ. However, M1Mϕ are not generated in γ-irradiated mice (WBI-mice), even though Mϕ are still present. WBI-mice are carriers of M2bMϕ, which inhibit Mϕ conversion from resident Mϕ to M1Mϕ. We have previously reported that sepsis stemming from Enterococcus faecalis oral infection is markedly mitigated in 5 Gy WBI-mice after M2bMϕ polarization using CCL1 antisense ODN. In this study, we examined the effect of CCL1 antisense ODN on spontaneous bacterial translocation and subsequent sepsis in 8 Gy WBI-mice. The ODN was administered (s.c., twice daily) to 8 Gy WBI-mice for 1 week starting 3 days after γ-irradiation. The efficacy of the treatment was evaluated by an increase in the percentage of survival in test groups, as compared with that of control groups. All control mice died within 22 days of γ-irradiation. However, 70% of the WBI-mice treated with 25 to 125 μg/mouse of the ODN survived more than 30 days after γ-irradiation. Severe bacteremia and bacterial growth in MLNs were not seen in WBI-mice treated with the ODN. M1Mϕ were isolated from MLNs of these mice, while M2bMϕ were not. These results indicate that the Mϕ polarization therapy using CCL1 antisense ODN is effective to mitigate spontaneous bacterial translocation and subsequent sepsis in mice exposed to 8 Gy of γ-irradiation.

Abstract
In previous studies, sepsis stemming for E. faecalis translocation and MRSA local infection has been greatly controlled in SAB-mice prophylactically treated with CCL1 antisense ODN. Effector cells (M1Mφ) in host antibacterial immunities are isolated from the infected SAB-mice after treatment with the ODN. In this study, the antibacterial resistance of SAB-mice therapeutically treated with the ODN was examined against infections with E. faecalis and MRSA. Mice 2 weeks after flame burn injury (3rd degree 25% TBSA) were infected with MRSA (106 CFU/mouse, i.v.). Decontaminated mice 2 weeks after burn injury were infected with E. faecalis (8 x 106 CFU/mouse, p.o.). These mice were therapeutically treated with the ODN (s.c., 10 mg/mouse) at various schedules starting 12 h after the infection. The antibacterial efficacies of the ODN were evaluated by reducing bacterial growth in blood and organs as compared to those of control mice. In the results, bacteria grew in the blood (>105 CFU/ml), liver (>106 CFU/gram), spleen (>105 CFU/gram), and kidneys (>107 CFU/gram) of control mice 3 to 5 days after MRSA infection. However, significant growth of the pathogen in their organs was not demonstrated in SAB-mice treated with the ODN 12, 24, and 36 h after the infection. Similar results were obtained in SAB-mice orally infected with E. faecalis. These results indicate that infections with MRSA and E. faecalis in SAB-mice are controllable by the therapeutic treatment with CCL1 antisense ODN.

Abstract
Abstract
In a murine model of γ-irradiation, bacterial translocation and subsequent sepsis have been effectively controlled by CCL1 antisense ODN, a M2b macrophage reverter. In the present study, we tried to obtain human CCL1 antisense ODN which is inhibitory on human M2b macrophages. Twenty human CCL1 antisense ODNs were synthesized based on the prediction of CCL1 mRNA secondary structure, calculation of GC content, and binding energy of ODNs. To evaluate the activity of these ODNs, an amount of CCL1 in culture fluids of M2b monocytes cultured with the ODNs was determined by ELISA. M2b monocytes were generated in vitro from healthy donor peripheral blood monocytes after stimulation with IL-1β and IgG in combination. In the results, 2 ODNs (HCA-15 ; CAACATCTGGAGAAGGGT : HCA-17 ; GGGCTGTGGTGATGATC), at doses of 20 and 100 µg/ml, suppressed 70-80% or more of CCL1 production by M2b monocytes. Also, decreased expression of IL-10 and CD163 was shown in M2b monocytes cultured with HCA-15 and HCA-17. The other 18 ODNs were not significantly active on the M2b macrophage reversion. These results suggest that HCA-15 and HCA-17 may be beneficial in controlling bacterial translocation and subsequent sepsis in patients with γ-irradiation.

Abstract
Bacterial translocation from microbiota causes serious sepsis in mice with chronic alcohol consumption (CAC-mice). Since innate lymphoid cells (ILCs) are cells to be involved in the prosperity and decoy of host antibacterial innate immunities, in this study, we tried to isolate ILCs from intestinal mucosal tissues of CAC-mice with various durations of alcohol consumption. CAC-mice were prepared by an oral gavage of 0.6 ml/day of 20% EtOH for 4 to 14 weeks. Lineage negative (lin-) cells were isolated from the intestinal mucosal tissue of CAC-mice. These cells were stimulated with PMA (50 ng/ml) and ionomycin (500 ng/ml) for 6 hours. Obtained cells were analyzed for ILC2 and ILC3 by flow cytometry, and culture fluids of lin- cells were assayed for IL-22 and IL-17A by ELISA. In the results, the percentage of CD45+CD90+RORγt+ cells (ILC3) in the lin- cell population was gradually increased in mice with alcohol consumption for 10-12 weeks (7.84% in average), as compared to be percentage of ILC3 in normal mice (0.67%). On the other hand, CD127+ICOS+Sca-1+ST2+ cells (ILC2) were minimally isolated from the lin- cell population of 4-12 week CAC-mice. Lin- cells from 12 week CAC-mice produced 400 pg/ml of IL-22 and 1.7 ng/ml of IL-17A. These results indicate that 10-12 week CAC-mice are carriers of ILC3 which play a role in the increased susceptibility of CAC-mice to enterococcal translocation and subsequent sepsis.

Abstract
Radiation victims who suffer from gastrointestinal injuries are extremely susceptible to gut-associated sepsis. In our previous studies, M1Mφ located in the lamina propria and mesenteric lymph nodes were shown to be major effector cells against bacterial translocation. However, M1Mφ were not generated in these organs of WBI-mice who are carriers of M2bMφ (inhibitor cells for Mφ conversion from resident Mφ to M1Mφ). CCL1 produced by M2bMφ is essential for the maintenance of M2bMφ properties. In this study, we examined the effect of CCL1 antisense ODN on gut-associated sepsis stemming from endogenous intestinal microflora in 9 Gy WBI-mice. CCL1 antisense ODN was administered s.c. to WBI-mice twice a day for 1 week starting 3 days post-exposure to γ-rays. This group of mice was designated as treated mice. The mortality rates and bacterial growth in the organs and blood of treated mice were compared to those of control mice (WBI-mice treated with scrambled ODN). In the results, control mice died within 14 days of γ-irradiation, while 30% of treated mice survived more than 30 days after the irradiation. Bacteria progressively grew in the mesenteric lymph nodes, liver and blood of control mice, while the pathogens were not isolated significantly from these organs of treated mice. These results indicate that sepsis stemming from spontaneous bacterial translocation is noticeably mitigated in WBI-mice treated with CCL1 antisense ODN.

Abstract
Sub-acutely burned mice are shown to be carriers of M2bMφ, these cells are characterized as inhibitor cells for Mφ conversion from resident Mφ to M1Mφ. CCL1 released from M2bMφ has been identified as an essential chemokine for the maintenance of M2bMφ properties, and M2bMφ derived from sub-acutely burned mice have reverted to resident Mφ after cultivation with CCL1 antisense ODN. In this study, we tried to determine the effect of CCL1 antisense ODN on M1Mφ generation in sub-acutely burned mice infected with MRSA. Two weeks after burn injury, the mice were infected i.v. with 105 CFU/mouse of MRSA, and then, treated with the ODN (s.c., twice a day, 10 μg/mouse). Two days after the infection, F4/80+ cells were isolated from the peritoneal cavities of the mice and assayed for IL-12+ cells. Also, the killing activity of these cells against MRSA was tested in vitro. In the results, a majority of Mφ from normal mice infected with MRSA were shown to be IL-12+ cells (>82%), while 10% or less of Mφ from burn mice infected with the pathogen were IL-12+ cells. However, a majority of Mφ isolated from burn mice infected with MRSA and treated with the ODN were shown to be IL-12+ cells. A majority of Mφ from burn mice infected with MRSA were not bactericidal, while Mφ preparations from the same mice additionally treated with the ODN were bactericidal. These results indicate that M1Mφ are induced after treatment with CCL1 antisense ODN in sub-acutely burned mice infected with MRSA.

Abstract
Staphylococcus aureus is frequently isolated from subacutely burned patients, and these infections easily develop into severe sepsis. M2bMφ have been characterized as the responsible cells on the increased susceptibility of SB-mice to staphylococcal infections, and SB-mice are carriers of M2bMφ. In this study, we tried to protect SB-mice (mice 10 to 30 days after burn injury) from a lethal dose infection of MRSA using CCL1 antisense ODN (an inhibitor of M2bMφ). Mice, 14 days after burn injury (20% total body surface area 3rd degree burns), were infected with 2 x 106 CFU/mouse of MRSA. Then, these mice were treated s.c. with 10 μg/mouse of CCL1 antisense ODN twice a day for 3 days (treated mice). As control mice, SB-mice were treated with scrambled ODN. The protective effect of the ODN against MRSA infection was evaluated by a reduction in the mortality rates of treated mice as compared with that of control mice. Also, bacterial growth in various organs of treated mice was compared with those of controls. In the results, all control mice died within 7 days of MRSA infection, while all treated mice were still alive after 7 days with the same infection. Bacteria grew in the liver, spleen and kidneys of control mice. However, the pathogen did not grow significantly in these organs of treated mice. These results indicate that sepsis caused by a lethal dose of MRSA infection in SB-mice is controlled by treatment with CCL1 antisense ODN.

Abstract
An essential host defense against gut-associated sepsis is a local antibacterial innate immunity mainly expressed by M1Mφ (IL-10-IL-12+ Mφ with marked bactericidal activity). Although Mφ are radioresistant, M1Mφ are not generated in bacterial translocation sites (lamina propria and mesenteric lymph nodes) of WBI-mice. M2bMφ (IL-10+IL-12-CCL1+ Mφ) appearing in response to radiation injuries inhibit Mφ conversion from resident Mφ to M1Mφ. CCL1 has been characterized as an essential chemokine for the maintenance of M2bMφ properties, and M2bMφ are shown to be major CCL1 producer cells. In this study, we tried to eliminate M2bMφ and induce M1Mφ in the bacterial translocation sites of WBI-mice by treatment with CCL1 antisense ODN. The ODN was administered s.c. to WBI-mice twice a day for 1 week starting 3 days after γ-irradiation (8-11 Gy). One day after the final treatment, these mice were stimulated orally with 107 heat-killed E. faecalis. Then, F4/80+ Mφ were isolated from the bacterial translocation sties of these mice and tested for their M1Mφ and M2bMφ properties. In the results, M1Mφ were not detected in the translocation sites of WBI-mice stimulated with the antigen. However, M1Mφ were isolated from WBI-mice treated with the ODN and stimulated with the antigen. M2Mφ were not isolated significantly from these mice. These results indicate that M1Mφ are inducible by the bacterial antigen in 8-11 Gy WBI-mice after treatment with CCL1 antisense ODN.

Abstract
To investigate the role of sulfate groups on the macrophage-stimulating activities of ascophyllan, we prepared desulfated ascophyllan, and its effects on RAW264.7 cells were compared with native ascophyllan. The chemical structural analysis revealed that nearly 21% of sulfate groups of ascophyllan were removed by desulfation reaction, while no significant changes in the molecular mass and monosaccharide composition occurred after desulfation. NO- and cytokine- (TNF-α and G-CSF) inducing activities of the desulfated ascophyllan on RAW264.7 cells were significantly decreased as compared to native ascophyllan. Furthermore, the activity of desulfated ascophyllan to induce reactive oxygen species (ROS) generation from RAW264.7 cells decreased to almost negligible level. Our results suggest that the level of sulfate groups of ascophyllan is an important structural element responsible for the macrophage-stimulating activities. Probably, even the limited removal of sulfate residues sensitive to desulfation reaction may result in significant decrease in the bioactivities of ascophyllan.

Abstract
Benign notochordal cell tumours have recently been described as intraosseous benign lesions of notochordal cell origin. The lesions are found in vertebral bodies in 20% of autopsy studies and are a potential precursor of chordoma. We report a rare case of lumbar vertebral chordoma that was thought to arise from a benign intraosseous notochordal cell tumour and which showed significant osteosclerotic change. Radiologically, the lumbar vertebral mass lesion showed hyperintensity on T2 weighted images, with scanty enhancement on post-contrast T1 weighted MR images. High uptake corresponding to the mass was noted on fluorine-18-fluorodeoxyglucose positron emission tomography. Bone biopsy revealed proliferation of the physaliphorous cells between thickened bone trabeculae; no nuclear mitosis was observed. Although the mass was diagnosed clinically as spinal chordoma, histopathology contained both benign notochordal cell tumour and conventional chordoma. After heavy particle (11C)-charged radiation therapy was applied to the lesion with a sufficient radiation field margin, the tumour volume significantly decreased and there was improvement in the patient's symptoms. On follow-up radiological studies, the tumour had markedly regressed and there was no tumour regrowth or distant metastasis. In this case report, benign notochordal cell tumour and conventional chordoma are histopathologically identified in the L1 vertebral body, which contains osteosclerotic and osteolytic areas. It is suggested that the benign notochordal cell tumour coexists with a conventional chordoma and that this histopathological finding supports a hypothetical relationship between benign notochordal cell tumour and chordoma.

Abstract
An organized hematoma is a chronic state of fibrotic tissue surrounding a hemorrhage. A mass lesion resulting from hematoma in the maxillary sinus was first reported in 1917, and the term, "blood boil," was clinically coined from such features as encapsulated blood and locally aggressive behavior. Subsequently, others have reported lesions with a similar appearance and clinical course, and now, in Japan, blood boil is used as a clinical term for such lesions. Factors that may predispose a patient to hematoma formation vary, and the pathogenesis of the mass is still uncertain. The lesions are mainly composed of an organized hematoma, regardless of their origin. We present 2 cases of organized maxillary sinus hematomas that have unusual radiologic findings and correlate these findings with the histopathologic findings.

Abstract
SUMMARY Total 89 patients with cervical ICA stenosis were treated by stenting. In 74 cases of stenting, we used our blocking balloon systems to prevent distal embolism. The morbidity and the mortality rate was 4.5% and 0%, respectively.Two(3%) of 74 cases showed distal embolism when blocking balloon catheter systems(BBCS) were used, while distal embolism occurred in four (27%) of 15 cases of stenting without BBCS. On diffusion- weighted MRI (DWI), hyperintense areas were detected in seven (47%) of 15 lesions when we used BBCS only during postdilatation. On the other hand, use of BBCS during predilatation as well as postdilatation reduced hyperintense areas on DWI, which were detected in three (25%) of 12 patients. Our blocking balloon catheter system is a useful device to reduce the risk of distal embolism, especially when we use it during not only postdilatation but predilatation.

Abstract
Glassy cell carcinoma (GCC) of the uterine cervix is a highly malignant tumor and has a poor prognosis. As yet, no effective systemic chemotherapy to this tumor has been reported. Here we describe a case of recurrent GCC that responded to paclitaxel and carboplatin combination treatment. The patient, a 32-year-old woman, with clinical staging FIGO IB1 disease had a radical hysterectomy and postoperative radiotherapy. Three months after initial treatment, she had a relapse as peritoneal dissemination, which was confirmed in the second surgery (adnectomy) and which did not respond to platinum-based conventional chemotherapy (cisplatin, adriamycin, cyclophosphamide and carboplatin, etoposide). The recurrent peritoneal tumors responded well to paclitaxel and carboplatin combination treatment. An elevated serum concentration of carcinoembryonic antigen (672 ng/ml) was reduced to 14.4 ng/ml by six such courses. Peritoneal histopathology confirmed a complete response in the third surgery (ileostomy) for adhesive ileus by the radiotherapy. This is the first report of effective systemic chemotherapy with paclitaxel and carboplatin to recurrent GCC of the uterine cervix.

Abstract
The variation of des-gamma-carboxyprothrombin (PIVKA-II, protein induced by vitamin K absence) levels in umbilical cord blood throughout gestation was examined using a highly sensitive method, electrochemiluminescence immunoassay (ECLIA). PIVKA-II levels in infants without any complications were low, but modestly high, exceeding the normal range of healthy adults during the preterm period, followed by a remarkable increase after the 37th week of gestation. Among infants complicated with severe preeclampsia a marked increase of PIVKA-II levels was observed in preterm infants, showing a good correlation with the existence ofinfarctions on the placenta. On the other hand, among infants complicated with preterm premature rupture of the membranes (PROM) in which antibiotics were administered during the prenatal period, a moderate elevation of PIVKA-II levels was observed. These data suggest that the normal range of PIVKA-II in fetuses is modestly high compared with adults and any deficient status of vitamin K would not exist throughout the preterm period. Nevertheless, the vitamin K status might readily fall into a deficient condition in term infants. Furthermore, it is notable that vitamin K deficiency would be induced in complicated gestation with severe preeclampsia and medication with antibiotics.

Abstract
SUMMARY Thirty-two patients with intracranial aneurysm were treated via the endovascular approach and clinical results and complications were accessed. The aneurysms were on the anterior circulation, posterior circulation and feeding artery of AVM in 17, 12 and three patients respectively. In 17 (anterior circulation aneurysm), 12 patients underwent parent artery occlusion. There were two complications: cerebral embolism due to premature detachment of balloons and cerebral infarct due to parent artery occlusion. In 12 (posterior circuration aneurysm), four patients had complications: three infarcts due to parent artery occlusion and one aneurysmal bleeding at the interventional procedure. Coil compactions occurred in four cases. There were no complications in cases associated with AVM. Use of detachable balloons for intra-aneurysmal occlusion and intra-aneurysmal embolisation for partially thrombosed giant aneurysm tends to result in ischemic lesions where patient outcome is poor. We must pay attention to avoid these complications even though intra-aneurysmal embolisation using microcoils is currently performed safely.
