complications in the long term, and the high financial burden on the health care system.Infections can lead to the onset of mood disorders in adults, partly through inflammatory mechanisms. However pediatric data are lacking. The aim of this study is to evaluate the relationship between depressive disorder and seropositivity of herpes virus infections in children. The sample group consisted of patients diagnosed with depressive disorder according to DSM-5 diagnostic criteria and healthy volunteers, being between 11 and 18 years with clinically normal mental capacity. All children completed DSM-5-Level-2 Depression Scale, DSM-5-Level-2 Irritability Scale, DSM-5-Level-2 Sleep Scale, DSM-5-Level-2 Somatic Symptoms Scale. The levels of anti-HSV1-IgG, anti-CMV-IgG, anti-EBNA, and anti-HHV6-IgG were examined in all participants. Patients with an antibody value above the cut-off values specified in the test kits were evaluated as seropositive. The mean age was 15.54 ± 1.57 years in the depression group (DG), 14.87 ± 1.76 years in the healthy control group (CG). There were 4 boys (11.2%), 32 girls (88.8%) in the DG, 9 boys (21.9%) and 32 girls (78.04%) in the CG. There was no statistically significant difference between the groups in terms of the presence of seropositivity of HSV1, CMV, EBV, and HHV6. HHV6 antibody levels were significantly higher in the DG (p = 0.000). A significant positive correlation was found between HHV6 antibodies and DSM-5 level-2 somatic symptoms scale score. HHV6 antibody levels were found to be significantly higher in patients with existing suicidal ideation in the DG (n = 13) compared to those without existing suicidal ideation in the DG (p = 0.043). HHV6 persistent infections may be responsible for somatic symptoms and etiology of suicidal ideation in childhood depressive disorder.Network meta-analysis (NMA) allows the combination of evidence on the effectiveness of several interventions. NMA has mainly been applied in the medical science field, whereas in the domain of psychology and educational sciences its use is less frequent. Consequently, systematic reviews that describe the characteristics of published NMAs are limited to the field of medicine, and nothing is known about the characteristics of NMAs published in the psychology and educational sciences field. However, this information is still relevant for the design of future simulation studies and for detecting good and bad research practices. Thus, this study describes the features of the meta-analytic datasets of NMAs published in the field of psychology and educational sciences, as well as their methodological characteristics, and compares them to those observed in the medical domain. Results show that the number of studies included is larger in NMAs from psychology and educational sciences, the most commonly used effect size is the standardized mean difference (unlike the odds ratio in medicine), the sample size is smaller, more intervention groups are included, and inconsistent effects are observed more often. These results can be used in future simulation studies to generate realistic datasets. Finally, we warn about the poor quality of reporting of some technical aspects of the NMA, such as the statistical model used.Angiogenesis is a prerequisite for tumor growth and invasion, and anti-angiogenesis has become a highlight in tumor treatment research. However, so far, there is no reliable solution for how to simultaneously visualize the relationship between tumor progression and angiogenesis. Bioluminescence imaging (BLI) has been broadly utilized and is a very promising non-invasive imaging technique with the advantages of low cost, high sensitivity, and robust specificity. In this chapter, we describe a dual bioluminescence imaging BLI protocol for tumor progression and angiogenesis through implanting murine breast cancer cell line 4T1 which stably expressing Renilla luciferase (RLuc) into the transgenic mice with angiogenesis-induced firefly luciferase (FLuc) expression. This modality enables us to synchronously monitor the tumor progression and angiogenesis in the same mouse, which has broad applicability in oncology studies.We recently expanded the commonly used dual luciferase assaying method toward multiplex hextuple luciferase assaying, allowing monitoring the activity of five experimental pathways against one control at the same time. In doing so, while our expanded assay utilizes a total of six orthogonal luciferases instead of two, this assay, conveniently, still utilizes the well-established reagents and principles of the widely used dual luciferase assay. Three quenchable D-luciferin-consuming luciferases are measured after addition of D-Luciferin substrate, followed by quenching of their bioluminescence (BL) and the measurement of three coelenterazine (CTZ)-consuming luciferases after addition of CTZ substrate, all in the same vessel. Here, we provide detailed protocols on how to perform such multiplex hextuple luciferase assaying to monitor cellular signal processing upstream of five transcription factors and their corresponding transcription factor-binding motifs, using a constitutive promoter as normalization control. The first protocol is provided on how to perform cell culture in preparation toward genetic or pharmaceutical perturbations, as well as transfecting a multiplex hextuple luciferase reporter vector encoding all luciferase reporter units needed for multiplex hextuple luciferase assaying. The second protocol details on how to execute multiplex hextuple luciferase assaying using a microplate reader appropriately equipped to detect the different BLs emitted by all six luciferases. Finally, the third protocol provides details on analyzing, plotting, and interpreting the data obtained by the microplate reader.Multiplex hextuple luciferase assaying allows monitoring the activity of five experimental pathways against one control at the same time. To perform multiplex hextuple luciferase assaying, six orthogonal luciferase reporter units are needed of which five are pathway-specific and one acts as a control for normalization. To ensure stoichiometric delivery of all six luciferase reporters in every transfected cell, synthetic assembly DNA cloning is used to stitch together all six luciferase reporter units into a single vector. Here, we provide a detailed three-step synthetic assembly DNA protocol to generate multiplex hextuple luciferase reporter plasmids for any five cellular signaling pathways of interest, against a control normalization pathway. A first protocol is provided on how to generate plasmids that contain novel transcription factor-binding motifs for specific transcription factors. A second protocol details on how to couple these novel transcription factor-binding motifs to one of five orthogonal luciferases to obtain specific luciferase reporters for cellular signaling pathways acting upstream of those transcription factor-binding motifs. Finally, a third protocol provides details on how to assemble orthogonal luciferase reporters for five cellular signaling pathways acting upstream of five unique transcription factor-binding motifs together with a control constitutive pathway luciferase reporter that will be used for normalization to obtain a final multiplex hextuple luciferase vector.Malaria hypnozoites are dormant parasite stages that reside inside hepatocytes. Upon activation, these stages can resume growth, causing new episodes of blood stage malaria infection. This chapter describes a fast and sensitive protocol for the detection of bioluminescent (BL) hypnozoites in vitro. Using transgenic Plasmodium cynomolgi parasites that differentially express the BL reporter proteins firefly luciferase and the ultrabright NanoLuc, hypnozoites can be distinguished from liver stage schizonts. This robust method sets the stage for implementation in large-scale drug screening platforms with the aim to find new compounds that eliminate hypnozoites.Bioluminescence imaging (BLI) is a technique that can be employed to quantify biological processes in living cells. When used in small animal models such as mice, BLI can provide both longitudinal and positional information regarding the biological process under investigation. Although perhaps best known for its utility in non-invasively quantifying tumor burden over time in experimental animals, BLI has also been applied in many pathogenesis models to track pathogen burden and responses to therapeutic interventions. In this chapter, we present a BLI-based method for tracing anatomical progression of lyssavirus infection in a mouse model. We also include validation methods to ensure that semiquantitative BLI data correlate well with viral load. Due to the longitudinal nature of this approach, lyssavirus pathogenesis and therapeutic intervention studies can be performed with far fewer animals than more traditional approaches, which typically require euthanasia of large animal groups at every data collection time point.Vector-borne protozoan parasites such as Plasmodium spp. Leishmania spp. and Trypanosoma brucei are responsible for several serious diseases. Significant advances in parasitology have been made using rodent models combined with live imaging techniques, including whole-mouse bioluminescence imaging (BLI). This technique has been applied to investigate parasite dissemination, infectivity, and growth. It has also been used in drug and vaccine testing. This chapter focuses on the methods that utilize whole-mouse BLI to (i) evaluate the homing and infectivity of Plasmodium berghei sporozoites; (ii) conduct in vivo testing of promising chemical entities against Leishmania infantum infection; and (iii) study molecular mechanisms of host susceptibility to Trypanosoma brucei brucei infection.In vivo bioluminescence imaging (BLI) methods enable the longitudinal and semi-quantitative monitoring of viral replication dynamics in small animal models and, thus, are useful for examining viral pathogenesis and the effect of antiviral drugs. Here, we describe an in vivo BLI method to evaluate the efficacy of antiviral drugs against rabies virus (RABV) infection in mice. We exemplify mice inoculated with recombinant RABV expressing red firefly luciferase and administered orally with the antiviral drug, favipiravir. For the imaging, mice are intraperitoneally administered with D-luciferin and placed in the dark chamber of an imaging system. The BL images are captured using a highly sensitive charge-coupled device camera. compound library inhibitor Image data are processed and analyzed using image analysis software.Bioluminescence (BL) imaging is a powerful non-invasive imaging modality widely used in a broad range of biological disciplines for many types of measurements. The applications of BL imaging in biomedicine are diverse, including tracking bacterial progression, research on gene expression patterns, monitoring tumor cell growth/regression or treatment responses, determining the location and proliferation of stem cells, and so on. It is particularly valuable when studying tissues at depths of 1 to 2 cm in mouse models during preclinical research. Here we describe the protocols for the therapeutic evaluation of a lymphatic drug delivery system (LDDS) using an in vivo BL imaging system (IVIS) for the treatment of metastatic lymph nodes (LNs) with 5-fluorouracil (5-FU). The LDDS is a method that directly injects anticancer drugs into sentinel LNs (SLNs) and delivers them to their downstream LNs. In the protocol, we show that metastases in the proper axillary LN (PALN) are induced by the injection of luciferase-expressing tumor cells into the subiliac LN (SiLN) of MXH10/Mo-lpr/lpr (MXH10/Mo/lpr) mice.
