Abstract
BACKGROUND/AIM Interstitial lung disease (ILD) is a serious adverse event (AE) associated with the use of immune checkpoint inhibitors (ICIs). However, the risk factors for developing ICI-related ILD remain poorly understood. Therefore, this study investigated the effect of concomitant analgesics on developing ICI-related ILD using the Japanese Adverse Drug Event Report (JADER) database. PATIENTS AND METHODS All the reported AE data were downloaded from the Pharmaceuticals and Medical Devices Agency website, and the JADER data between January 2014 and March 2021 were analysed. The relationship between ICI-related ILD and concomitant use of analgesics was assessed using reporting odds ratio (ROR) and 95% confidence interval. We investigated whether the effect of developing ILD varied according to the type of analgesics used during ICI treatment. RESULTS Positive signals for ICI-related ILD development were detected for the concomitant use of the narcotic analgesics codeine, fentanyl and oxycodone, but not with morphine. In contrast, there were no positive signals for the concomitant use of the non-narcotic analgesics celecoxib, acetaminophen, loxoprofen and tramadol. An increased ROR for ICI-related ILD in cases with concomitant use of narcotic analgesics was observed in a multivariate logistic analysis adjusted by sex and age. CONCLUSION These results suggest that the concomitant use of narcotic analgesics is involved in the development of ICI-related ILD.

Abstract
We have already reported that ovariectomized (OVX) rats reduced the spontaneous activity during the dark period due to the decease of serotonin release in the amygdala. In this study, we examined the potential of sertraline, a selective serotonin reuptake inhibitor, on the recovery of less spontaneous activity seen in mice with OVX-induced despair-like behaviors. Female 9-week old ICR mice were underwent either OVX or sham surgery. Sertraline (10 mg/kg/day, s.c.) or saline were started to administer to each group for 8 weeks (6 times/week) from the 8th week after OVX. Each spontaneous activity of mouse was evaluated during the dark period (19:00-07:00) using an infrared sensor. Moreover, mRNA expression levels of tryptophan hydroxylase (TPH) and X-box binding protein 1 (XBP1) were measured in the hippocampus and prefrontal cortex using by a real-time PCR method. We found out that the OVX-induced despair-like behaviors were improved by the continuous administration of sertraline. After treatment of OVX, our real-time PCR data showed that sertraline significantly suppressed the upregulation of XBP1 expression levels in both hippocampus and prefrontal cortex, although this suppression of the downregulation of TPH expression levels was seen in only hippocampus. These results suggest that sertraline improves the decrease in spontaneous activity induced by OVX assessed by the hippocampus suppressing decreased serotonin synthesis in the serotonergic neuron.

Abstract
BACKGROUND Decreases in female hormones not only affect bone metabolism and decrease bone mass, but also affect the central nervous system, causing brain disorders such as depression and dementia. Administration of estradiol by hormone replacement therapy can improve dementia, while reduced estradiol in ovariectomized (OVX) model rats can reduce both bone density and locomotor activity. The antidepressant fluvoxamine, which is widely used in clinical practice, can improve this effect on locomotor reduction. Similarly, lactoferrin (LF) can reportedly improve inhibitory locomotion due to stress. OBJECTIVE In this study, we examined the effect of LF on neurite outgrowth in vitro and in vivo using PC12 cells and rats, respectively. METHODS We performed an in vivo study in which 8-week-old female OVX rats were administered LF five days a week for 6 weeks from the day after surgery. After administration was completed, spontaneous locomotor activity in the dark period, immobility time in a forced swim test, and release amount of dopamine and serotonin in the brain were measured. RESULTS LF was found to have a neurite outgrowth function in PC12 cells. Moreover, LF was found to improve OVX-induced decreases in locomotor activity and increases in immobility time in the forced swim test. Furthermore, the administration of LF elicited significant recovery of decreased dopamine and serotonin release in the brains of OVX group rats. CONCLUSION These results strongly suggest that LF improved OVX-induced decreases in momentum during the dark period and, moreover, that release of dopamine and serotonin in the brain was involved in this effect.

Abstract
The mechanistic/mammalian target of rapamycin complex 1 (mTORC1) regulates cellular function in various cell types. Although the role of mTORC1 in skeletogenesis has been investigated previously, here we show a critical role of mTORC1/4E-BPs/SOX9 axis in regulating skeletogenesis through its expression in undifferentiated mesenchymal cells. Inactivation of Raptor, a component of mTORC1, in limb buds before mesenchymal condensations resulted in a marked loss of both cartilage and bone. Mechanistically, we demonstrated that mTORC1 selectively controls the RNA translation of Sox9, which harbors a 5′ terminal oligopyrimidine tract motif, via inhibition of the 4E-BPs. Indeed, introduction of Sox9 or a knockdown of 4E-BP1/2 in undifferentiated mesenchymal cells markedly rescued the deficiency of the condensation observed in Raptor-deficient mice. Furthermore, introduction of the Sox9 transgene rescued phenotypes of deficient skeletal growth in Raptor-deficient mice. These findings highlight a critical role of mTORC1 in mammalian skeletogenesis, at least in part, through translational control of Sox9 RNA. mTORC1 controls skeletogenesis both in skeletogenic progenitors and in chondrocytes mTORC1/4E-BPs cascade regulates the translation of Sox9 RNA SOX9 is a critical mediator in the control of skeletogenesis by mTORC1 in vivo

Abstract
This study evaluated whether imidazolines can induce autophagy in the murine macrophage-like cell line RAW264.7. Idazoxan increased the content of LC3-II, an autophagosomal marker, in RAW264.7 cells. To determine whether this effect was due to the induction of its synthesis or inhibition of its degradation, idazoxan treatment was performed in the presence of bafilomycin A1, which blocks autophagosome-lysosome fusion, as well as Pepstatin A and E-64d, both of which block protein degradation in autolysosomes. An increased content of LC3-II was observed in the presence of bafilomycin A1 as well as the protease inhibitors. Furthermore, an increased number of autophagosomes was observed following idazoxan treatment using an autophagosome-specific dye. This indicated that idazoxan induced autophagy. Other imidazolines, such as efaroxan, clonidine, and 2-(2-benzofuranyl)-2-imidazoline, also increased the LC3-II content in RAW264.7 cells in the presence of bafilomycin A1. Taken together, these results indicate that some imidazolines, including idazoxan, can induce autophagy in RAW264.7 cells.

Abstract
The antimicrobial peptide KLKLLLLLKLK-NH2 was developed based on sapesin B, and synthesized using D-amino acids. Biochemical properties of the D-form and L-form KLKLLLLLKLK-NH2 peptides were compared. In order to limit the effects due to bacterial resistance to proteolysis, antimicrobial activities of the peptides were evaluated after short-term exposure to bacteria. D-form KLKLLLLLKLK-NH2 exhibited higher antimicrobial activities than L-form KLKLLLLLKLK-NH2 against bacteria, including Staphylococcus aureus and Escherichia coli. In contrast, both the D-form and L-form of other antimicrobial peptides, including Mastoparan M and Temporin A, exhibited similar antimicrobial activities. Both the D-form KLKLLLLLKLK-NH2 and L-form KLKLLLLLKLK-NH2 peptides preferentially disrupted S. aureus-mimetic liposomes over mammalian-mimetic liposomes. Furthermore, the D-form KLKLLLLLKLK-NH2 increased the membrane permeability of S. aureus more than the L-form KLKLLLLLKLK-NH2. Thus suggesting that the enhanced antimicrobial activity of the D-form was likely due to its interaction with bacterial cell wall components. S. aureus peptidoglycan preferentially inhibited the antimicrobial activity of the D-form KLKLLLLLKLK-NH2 relative to the L-form. Furthermore, the D-form KLKLLLLLKLK-NH2 showed higher affinity for S. aureus peptidoglycan than the L-form. Taken together, these results indicate that the D-form KLKLLLLLKLK-NH2 peptide has higher antimicrobial activity than the L-form via a specific association with bacterial cell wall components, including peptidoglycan.

Abstract
A compact and high-particle-flux thermal-lithium-beam source for two-dimensional measurement of electron density profiles has been developed. The thermal-lithium-beam oven is heated by a carbon heater. In this system, the maximum particle flux of the thermal lithium beam was ~4 × 10(19) m(-2) s(-1) when the temperature of the thermal-lithium-beam oven was 900 K. The electron density profile was evaluated in the small tokamak device HYBTOK-II. The electron density profile was reconstructed using the thermal-lithium-beam probe data and this profile was consistent with the electron density profile measured with a Langmuir electrostatic probe. We confirm that the developed thermal-lithium-beam probe can be used to measure the two-dimensional electron density profile with high time and spatial resolutions.

Abstract
Major depression is a complex disorder characterized by genetic and environmental interactions. Selective serotonin reuptake inhibitors (SSRIs) effectively treat depression. Neurogenesis following chronic antidepressant treatment activates brain derived neurotrophic factor (BDNF) signaling. In this study, we analyzed the effects of the SSRI fluvoxamine (Flu) on locomotor activity and forced-swim behavior using chronic dexamethasone (cDEX) infusions in mice, which engenders depression-like behavior. Infusion of cDEX decreased body weight and produced a trend towards lower locomotor activity during darkness. In the forced-swim test, cDEX-mice exhibited increased immobility times compared with mice administered saline. Flu treatment reversed decreased locomotor activity and mitigated forced-swim test immobility. Real-time polymerase chain reactions using brain RNA samples yielded significantly lower BDNF mRNA levels in cDEX-mice compared with the saline group. Endoplasmic reticulum stress-associated X-box binding protein-1 (XBP1) gene expression was lower in cDEX-mice compared with the saline group. However, marked expression of the XBP1 gene was observed in cDEX-mice treated with Flu compared with mice given saline and untreated cDEX-mice. Expression of 5-HT2A and Sigma-1 receptors decreased after cDEX infusion compared with the saline group, and these decreases normalized to control levels upon Flu treatment. Our results indicate that the Flu moderates reductions in voluntary activity following chronic dexamethasone infusions in mice via recovery of BDNF signal cascades.

Abstract
UNLABELLED BACKGROUND Reelin regulates neuronal positioning in cortical brain structures and neuronal migration via binding to the lipoprotein receptors Vldlr and Lrp8. Reeler mutant mice display severe brain morphological defects and behavioral abnormalities. Several reports have implicated reelin signaling in the etiology of neurodevelopmental and psychiatric disorders, including autism, schizophrenia, bipolar disorder, and depression. Moreover, it has been reported that VLDLR mRNA levels are increased in the post-mortem brain of autistic patients. METHODS We generated transgenic (Tg) rats overexpressing Vldlr, and examined their histological and behavioral features. RESULTS Spontaneous locomotor activity was significantly increased in Tg rats, without detectable changes in brain histology. Additionally, Tg rats tended to show performance deficits in the radial maze task, suggesting that their spatial working memory was slightly impaired. Thus, Vldlr levels may be involved in determining locomotor activity and memory function. CONCLUSIONS Unlike reeler mice, patients with neurodevelopmental or psychiatric disorders do not show striking neuroanatomical aberrations. Therefore, it is notable, from a clinical point of view, that we observed behavioral phenotypes in Vldlr-Tg rats in the absence of neuroanatomical abnormalities.

Abstract
The hematogenous metastasis of cancer consists of a multistep process. It is surmised that a number of interactions between cancer and endothelial cells occur, with cell adhesion molecules playing certain roles in this process. The authors conducted an investigation on the interaction between human cancer cells and cultured murine endothelial cells (F-2 cells) in vitro, and on its relationship with the metastatic activity of cancer cells in vivo. A correlation was found between the degree of expression of carbohydrate antigens on the cell surface and adhesion of cancer cells to F-2 cells. Five of 13 examined cell lines showed liver metastasis after inoculation to the spleen of nude mice. These cell lines showed not only a strong binding activity to F-2 cells but implantation in F-2 cells in vitro was also observed. These findings suggest that adhesion to, and implantation in endothelial cells are necessary for the induction of distant metastasis. Treatment with antibodies against carbohydrate antigens inhibited the formation of liver metastasis in nude mice. It is possible that strategies to interfere with the function of cell adhesion molecules may be formulated to result in the decreased distant metastasis of cancer.

Abstract
Using micromechanical force magnetometry, we have measured the magnetization of the strong-leg spin-1/2 ladder compound (C(7)H(10)N)(2)CuBr(2) at temperatures down to 45 mK. Low-temperature magnetic susceptibility as a function of field exhibits a maximum near the critical field H(c) at which the magnon gap vanishes, as expected for a gapped one-dimensional antiferromagnet. Above H(c) a clear minimum appears in the magnetization as a function of temperature, as predicted by theory. In this field region, the susceptibility in conjunction with our specific-heat data yields the Wilson ratio R(W). The result supports the relation R(W)=4K, where K is the Tomonaga-Luttinger-liquid parameter.

Abstract
This report reviews the research on the factors that cause autism. In several studies, these factors have been verified by reproducing them in autistic animal models. Clinical research has demonstrated that genetic and environmental factors play a major role in the development of autism. However, most cases are idiopathic, and no single factor can explain the trends in the pathology and prevalence of autism. At the time of this writing, autism is viewed more as a multi-factorial disorder. However, the existence of an unknown factor that may be common in all autistic cases cannot be ruled out. It is hoped that future biological studies of autism will help construct a new theory that can interpret the pathology of autism in a coherent manner. To achieve this, large-scale epidemiological research is essential.

Abstract
The expression level of hnRNP C1/C2 protein has been reported to be significantly decreased in the post-mortem brain of schizophrenic patients. In this study, we investigated whether overexpression of the hnRNP C variants hnRNP C1 and C2 changed the expression of myelination-related genes in the human neuroblastoma cell line SK-N-SH. In both hnRNP C1- and C2-overexpressing cells, the expression of quaking (QKI)-6 and QKI-7 significantly increased or decreased compared to the control, respectively. Intriguingly, QKI-5 and myelin basic protein were markedly up- or down-regulated by overexpressing hnRNP C2, respectively. Our findings are the first to demonstrate distinct functions of hnRNP C1 and C2, and may be helpful in understanding the functions of these molecules. These findings indicate that altered expression levels of hnRNP C in the brain of patients with schizophrenia could be involved in the pathophysiology of this disease through alteration of the QKI isoform and myelin basic protein expression.

Abstract
Autism is a neurodevelopmental disorder of social behavior, which is more common in males than in females. The causes of autism are unknown; there is evidence for a substantial genetic component, but it is likely that a combination of genetic, environmental and epigenetic factors contribute to its complex pathogenesis. Rodent models that mimic the behavioral deficits of autism can be useful tools for dissecting both the etiology and molecular mechanisms. This review discusses animal models of autism generated by prenatal or neonatal environmental challenges, including virus infection and exposure to valproic acid (VPA) or stress. Studies of viral infection models suggest that interleukin-6 can influence fetal development and programming. Prenatal exposure to the histone deacetylase inhibitor VPA has been linked to autism in children, and male VPA-exposed rats exhibit a spectrum of autistic-like behaviors. The experience of prenatal stress produces male-specific behavioral abnormalities in rats. These effects may be mediated by epigenetic modifications such as DNA methylation and histone acetylation resulting in alterations to the transcriptome.

Abstract
PagL, a lipid A deacylase, is unique in that it is latent in the outer membrane of Salmonella enterica serovar Typhimurium. Several point mutations in the extracellular loops of PagL, which do not affect its enzymatic activity, release it from this latency. Precipitation analysis revealed that latent wild-type PagL associated with lipopolysaccharide, but non-latent PagL mutants did not. In contrast, non-latent PagL mutants preferentially associated with some membrane proteins. Precipitation analysis using inactive PagL mutants demonstrated that membrane lipid A deacylation did not affect association. These results indicate that mutations in the lipid A deacylase PagL which relieve the enzyme from its latency affect the ability of PagL to interact with lipopolysaccharide.

Abstract
High mobility group protein A1a (HMGA1a) acts as an architectural transcription factor and influences a diverse array of normal biological processes. It binds AT-rich sequences, and previous reports have demonstrated HMGA1a binding to the authentic promoters of various genes. However, the precise sequences that HMGA1a binds to remain to be clarified. Therefore, in this study, we searched for the sequences with the highest affinity for human HMGA1a using an existing SELEX method, and then compared the identified sequences with known human promoter sequences. Based on our results, we propose the sequences “-(G/A)-G-(A/T)-(A/T)-A-T-T-T-” as HMGA1a-binding candidate sequences. Furthermore, these candidate sequences bound native human HMGA1a from SK-N-SH cells. When candidate sequences were analyzed by performing FASTAs against all known human promoter sequences, 500–900 sequences were hit by each one. Some of the extracted genes have already been proven or suggested as HMGA1a-binding promoters. The candidate sequences presented here represent important information for research into the various roles of HMGA1a, including cell differentiation, death, growth, proliferation, and the pathogenesis of cancer.

Abstract
Epidemiological data suggest a relationship between maternal infection and a high incidence of schizophrenia in offspring. An animal model based on this hypothesis was made by injecting double-stranded RNA, polyinosinic-polycytidylic acid (poly-I:C), into early pregnant mice, and their offspring were examined for biochemical and histological abnormalities. Mouse brains were examined with special reference to oligodendrocytes, which have been implicated in several neurodevelopmental disorders. We detected a significant decrease of myelin basic protein (MBP) mRNA and protein at early postnatal periods in poly-I:C mice. MBP immunocytochemistry and electron microscopy revealed that the hippocampus of juvenile poly-I:C mice was less myelinated than in PBS mice, with no significant loss of oligodendrocytes. In addition, axonal diameters were significantly smaller in juvenile poly-I:C mice than in control mice. These abnormalities reverted to normal levels when the animals reached the adult stage. These findings suggest that retarded myelination and axonal abnormalities in early postnatal stages caused by maternal immune activation could be related to schizophrenia-related behaviors in adulthood.

Abstract
Maternal virus infection or maternal polyinosinic-polycytidilic acid injection confers behavioral alterations including deficit in prepulse inhibition on the offspring. We previously found delayed myelination specifically in the early postnatal hippocampus in the polyinosinic-polycytidilic acid-injection model. To test whether the transient delay in myelination in the juvenile hippocampus leads to abnormal behaviors after adolescence, we injected lysophosphatidylcholine, a potent demyelinating agent, into the ventral hippocampus of the 10-day-old rat. The lysophosphatidylcholine treatment yielded hypomyelination at postnatal day 16, but myelination reverted to normal level in the adult rat. Neuronal arrays and morphology were not disturbed in this model. We then performed a battery of behavioral tests on the lysophosphatidylcholine-treated and control PBS-injected rats. The lysophosphatidylcholine-treated rats showed deficit in prepulse inhibition, motor hyperactivity in response to methamphetamine and anxiety-related behaviors, all of which are typical behaviors observed in the maternal infection models. These findings suggest that the timing of myelination in the early postnatal hippocampus is crucial for the proper development of sensorimotor and emotional functions. The lysophosphatidylcholine-treated rat without a gross anatomical defect is useful as a model for psychotic disorders.
