    Abstract Accurate and rapid analytical methods are essential for the detection and identification of biological warfare agents (BWA). Although various studies have investigated the use of MALDI‐TOF MS for bacterial classification, only a few studies have examined the applicability of method for the identification of BWAs. This study aimed to generate, collect and analyse Bacillus spore aerosol particles of 2–10� μm, the optimal size of a BWA. Bacillus spore aerosol particles of 2–10� μm were rapidly analysed using direct in situ MALDI‐TOF MS without pretreatment processes. A mass spectrum of Bacillus spore aerosol particles was successfully detected. For real‐time detection and identification, a mass spectral database of Bacillus spores was constructed, and an algorithm was developed and applied. Bacillus spore particles were rapidly detected and identified by MS, which can be used for the detection and inspection of BWAs. SIGNIFICANCE AND IMPACT OF THE STUDY: Methods that permit accurate and fast detection and identification are essential in the case of pathogens such as Bacillus anthracis, which can be used as biological warfare agents or bioterrorism materials. Here, direct in situ MALDI‐TOF MS allowed the high‐throughput detection and identification of aerosolized Bacillus spore particles, and this method could be effectively applied for the detection and inspection of BWAs. In this context, we believe that this method may contribute to the realization of real‐time and on‐site identification of BWAs.

    Abstract This study was to provide the information for optimum utilization of the air-conditioning system in the human health and energy saving perspective. Subjects were 17 male and female college students(7 males and 10 females) with normal weight. They wore a short sleeved shirt, knee length trousers, socks, and underwear(0.4clo). They were asked to choose the preferred temperature from different environmental temperatures(28℃, 25℃). The physiological responses were measured and the subjective sensation was voted during the step changes of environmental temperature, starting at 28℃ to 25℃ with 1℃ decrease every 20 minutes. The preferred temperature was 25.9±0.4℃ for males and 26.9±0.2℃ for females at 28℃ and 24.8±0.6℃ for males and 25.6±0.1℃ for females at 25℃. The preferred temperature decreased about 1.3℃ while the environmental temperature changed 3℃. During the environmental step changes, mean skin temperature decreased more in females while the oxygen uptake and rectal temperature were kept constant for both males and females. We found the preferred temperature was affected by the exposed temperature and the thermal sensation in the condition. Subjects preferred a lower environmental temperature when they were exposed to a lower temperature with cooler sensation. Therefore, in the perspective of human health and energy saving, it is recommended to start setting the air-conditioning temperature higher than the preferred temperature.

    Abstract Background and purpose: Recently, the DNA damage response (DDR) has emerged as a promising target for anticancer drug development. In our previous study, we identified several DDR-inhibiting compounds via high-content screening of a small molecule library using γH2AX foci as a biomarker. Here, we studied the effects of the DNA damage response inhibitor DDRI-18 (3,3'-(1H,3'H-5,5'-bibenzo[d]imidazole-2,2'-diyl)dianiline) on DDR.
    Experimental approach: Osteosarcoma U2OS cells were treated with etoposide to induce DDR. The nuclear foci of γH2AX and other signalling molecules in DDR were visualized by immunofluorescence and quantified using an IN Cell Analyzer. The DNA repair capacity of cells was analysed using the comet assay and in vivo DNA end-joining assay. Cell survival after drug treatment was quantified using the MTT assay, and apoptotic cell death was analysed by Annexin V staining and flow cytometry.
    Key results: DDRI-18 inhibited the non-homologous end-joining (NHEJ) DNA repair process and delayed the resolution of DNA damage-related proteins (γH2AX, ATM and BRCA1) from DNA lesions at a later phase of DDR. Furthermore, DDRI-18 enhanced the cytotoxic effects of anticancer DNA-damaging drugs, including etoposide, camptothecin, doxorubicin and bleomycin. This synergistic effect on cell death was shown to be due to caspase-dependent apoptosis.
    Conclusions and implications: We identified a chemical compound, DDRI-18, that has chemosensitization activity. Although the target molecule and mechanism of action of DDRI-18 remain unknown, DDRI-18 is an effective chemosensitizing agent and may improve the therapy with classical anticancer drugs.

    Abstract Coronavirus subgenomic mRNA possesses a 5'-end leader sequence which is derived from the 5' end of genomic RNA and is linked to the mRNA body sequence. This study examined whether coronavirus transcription involves a discontinuous transcription step; the possibility that a leader sequence from mouse hepatitis virus (MHV) genomic RNA could be used for MHV subgenomic defective interfering (DI) RNA transcription was examined. This was tested by using helper viruses and DI RNAs that were easily distinguishable. MHV JHM variant JHM(2), which synthesizes a subgenomic mRNA encoding the HE gene, and variant JHM(3-9), which does not synthesize this mRNA, were used. An MHV DI RNA, DI(J3-9), was constructed to contain a JHM(3-9)-derived leader sequence and an inserted intergenic region derived from the region preceding the MHV JHM HE gene. DI(J3-9) replicated efficiently in JHM(2)- or JHM(3-9)-infected cells, whereas synthesis of subgenomic DI RNAs was observed only in JHM(2)-infected cells. Sequence analyses demonstrated that the 5' regions of both helper virus genomic RNAs and genomic DI RNAs maintained their original sequences in DI RNA-replicating cells, indicating that the genomic leader sequences derived from JHM(2) functioned for subgenomic DI RNA transcription. Replication and transcription of DI(J3-9) were observed in cells infected with an MHV A59 strain whose leader sequence was similar to that of JHM(2), except for one nucleotide substitution within the leader sequence. The 5' region of the helper virus genomic RNA and that of the DI RNA were the same as their original structures in virus-infected cells, and the leader sequence of DI(J3-9) subgenomic DI RNA contained the MHV A59-derived leader sequence. The leader sequence of subgenomic DI RNA was derived from that of helper virus; therefore, the genomic leader sequence had a trans-acting property indicative of a discontinuous step in coronavirus transcription.

    Abstract Previously, we established a system whereby an intergenic region from mouse hepatitis virus (MHV) inserted into an MHV defective interfering (DI) RNA led to transcription of a subgenomic DI RNA in helper virus-infected cells. By using this system, the duration of a primary transcription initiation activity which transcribes subgenomic-size RNAs from the genomic-size RNA template in MHV-infected cells was examined. Efficient DI genomic and subgenomic RNA synthesis was observed when the DI RNA was transfected at 1, 3, 3.5, 5, and 6 h postinfection, indicating that all activities which are necessary for MHV RNA synthesis are present continuously during the first 6 h of infection. The effect of subgenomic DI RNA synthesis on DI genomic RNA replication was then examined. Replication efficiency of the DI genomic RNA which synthesized the subgenomic RNA was approximately 70% lower than that of DI genomic RNA which did not synthesize the subgenomic DI RNA in MHV-infected cells. Cotransfection of two different-size DI RNAs demonstrated that replication of the larger DI RNA was strongly inhibited by replication of the smaller genomic DI RNA. Cotransfection of two DI RNA species of the same length into MHV-infected cells demonstrated that reduced replication of the genomic DI RNA which synthesizes the subgenomic RNA did not affect the replication of cotransfected DI RNA, demonstrating that the reduction in DI genomic RNA replication works only in cis, not in trans. Therefore, the previously proposed hypothesis that coronavirus, subgenomic RNA synthesis may inhibit the replication of genomic RNA by competing for a limited amount of virus-derived factors seems unlikely. Possible mechanisms of coronavirus transcription are discussed.
