Abstract
INTRODUCTION Drowning is a comprehensive and exclusive diagnosis at autopsy. Autopsy findings such as pleural effusion and waterlogged lungs contribute to the diagnosis. Herein, we aim to reveal the practical usefulness and postmortem changes of the maxillary sinus fluid volume to diagnose drowning. METHODS We evaluated 52 drowning and 59 nondrowning cases. The maxillary sinus fluid volume was measured using a computed tomography (CT) scan, and pleural effusion volume and lung weight were manually measured at autopsy. The utility of these three indices for diagnosing drowning and its postmortem changes was evaluated. RESULTS The maxillary sinus fluid volume was significantly higher in drowning cases than in other external causes and cardiovascular death cases. Receiver operating characteristic curve analysis revealed that a total maxillary sinus fluid volume >1.04 mL more usefully indicated drowning (odds ratio, 8.19) than a total pleural effusion volume >175 mL (odds ratio, 7.23) and a total lung weight >829 g (odds ratio, 2.29). The combination of maxillary sinus fluid volume and pleural effusion volume more effectively predicted drowning than one index alone. Moreover, the maxillary sinus fluid volume was less influenced by the postmortem interval than the other two indices up to a week after death. CONCLUSION Maxillary sinus fluid volume can be more useful than pleural effusion volume and lung weight with higher sensitivity and odds ratio for diagnosing drowning. IMPLICATIONS FOR PRACTICE Fluid accumulation in both the maxillary sinuses strongly predicts drowning in the postmortem imaging.

Abstract
A chiral spin soliton lattice (CSL), one of the representative systems of a magnetic superstructure, exhibits reconfigurability in periodicity over a macroscopic length scale. Such coherent and tunable characteristics of the CSL lead to an emergence of elementary excitation of the CSL as phononlike modes due to translational symmetry breaking and bring a controllability of the dispersion relation of the CSL phonon. Using a broadband microwave spectroscopy technique, we directly found that higher-order magnetic resonance modes appear in the CSL phase of a chiral helimagnet CrNb_{3}S_{6}, which is ascribed to the CSL phonon response. The resonance frequency of the CSL phonon can be tuned between 16 and 40 GHz in the vicinity of the critical field, where the CSL period alters rapidly. The frequency range of the CSL phonon is expected to extend over 100 GHz as extrapolated on the basis of the theoretical model. The present results indicate that chiral helimagnets could work as materials useful for broadband signal processing in the millimeter-wave band.

Abstract
By using the LC-MS/MS method developed by us, we determined the residual amounts of acaricides in honey samples commercially available in Tokyo from April 2015 to March 2021. The results of analyzing 127 honey samples, amitraz was detected in 85 samples at the level of 1.1-34.1 μg/kg. Propargite was detected in 3 samples at 2.4-3.8 μg/kg. None of them was beyond the Japanese MRLs or uniform limits. In these survey for 6 years, amitraz was detected in high rate throughout the year. But, the present results imply that amitraz has been used properly in actual bee-keeping because of no violation of MRL and less fluctuation in the detected levels. On the other hand, propargite was detected at the levels over LOQ in domestic honey samples for the first time in 2020, which may suggest a new trend of acaricide use in apiculture in Japan.

Abstract
In this paper, a high sensitivity compact multi-slot sub-wavelength Bragg grating refractive index (RI) sensor was investigated. The structural parameters were optimized for higher sensitivity to RI change of the surrounding medium from viewpoints of a wavelength shift, an extinction ratio and a transmission loss, and a record-high sensitivity was experimentally demonstrated with a compact size. In this sensor, the first side-lobe at the Bragg grating (BG) stop-band end was focused as a sensing peak wavelength for moderate transmission loss and efficient sensing. To realize the compactness, a period count of the BG was kept as small as 20. By increasing the RI of the surrounding medium, the sensing peak shifts toward a longer wavelength side; thus due to the high sharpness and easy tracing of the first side-lobe, the device worked as an efficient RI sensor. The structural optimization was carried out by using 3D finite-difference time-domain (FDTD) simulation approach, and also influences of the structural parameters to sensitivities were discussed. Based on these optimized parameters, the devices were fabricated using the lift-off technique. By exposing the sensor to various liquid samples with different RIs such as pure water, sugar-dissolved water with various concentrations, acetone and isopropyl alcohol (IPA), a record-high sensitivity of 730 nm/RIU was attained for a sensor fabricated on SOI platforms with a length of as small as 9.5 µm and a transmission loss of 3 dB.

Abstract
ABSTRACT
The stress softening behaviors of sulfur cross-linked unfilled guayule natural rubber (S-GR) and sulfur cross-linked unfilled dandelion natural rubber (S-DR) under cyclic deformation were characterized by simultaneous wide angle X-ray diffraction and tensile measurements under cyclic deformation. The behaviors were found to be affected by their strain-induced crystallization (SIC) phenomena and aggregated nonrubber components. The stress softening degree at stretching ratio = 8.0 of S-DR was almost two times larger than that of S-GR. Additionally, the hysteresis loss and residual strain of S-DR were much higher than those of S-GR in the same cycle. The key factors that caused the increase in their degree of stress softening were the increase in average volume and the decrease in average number of strain-induced crystallites upon cyclic deformation, not the insignificant decrease in crystallinity. The breakage of the aggregated nonrubber components is a main origin of stress softening behaviors for S-GR and S-DR because their SIC behaviors also were significantly influenced by the aggregates of nonrubber components in the rubber matrixes. Both the effects of nonrubber components and SIC on stress softening were more dominant in S-DR than in S-GR, probably owing to the larger amount of aggregated nonrubber components in the former than in the latter. The results will be useful in effectively using guayule and dandelion natural rubbers as alternatives to Hevea natural rubber in the rubber industry.

Abstract
BACKGROUND Recent preclinical and phase I studies have reported that rebamipide decreased the severity of chemoradiotherapy-induced oral mucositis in patients with oral cancer. This placebo-controlled randomized phase II study assessed the clinical benefit of rebamipide in reducing the incidence of severe chemoradiotherapy-induced oral mucositis in patients with head and neck cancer (HNC). METHODS Patients aged 20-75 years with HNC who were scheduled to receive chemoradiotherapy were enrolled. Patients were randomized to receive rebamipide 2% liquid, rebamipide 4% liquid, or placebo. The primary endpoint was the incidence of grade ≥ 3 oral mucositis determined by clinical examination and assessed by central review according to the Common Terminology Criteria of Adverse Events version 3.0. Secondary endpoints were the time to onset of grade ≥ 3 oral mucositis and the incidence of functional impairment (grade ≥ 3) based on the evaluation by the Oral Mucositis Evaluation Committee. RESULTS From April 2014 to August 2015, 97 patients with HNC were enrolled, of whom 94 received treatment. The incidence of grade ≥ 3 oral mucositis was 29% and 25% in the rebamipide 2% and 4% groups, respectively, compared with 39% in the placebo group. The proportion of patients who did not develop grade ≥ 3 oral mucositis by day 50 of treatment was 57.9% in the placebo group, whereas the proportion was 68.0% in the rebamipide 2% group and 71.3% in the rebamipide 4% group. The incidences of adverse events potentially related to the study drug were 16%, 26%, and 13% in the placebo, rebamipide 2%, and rebamipide 4% groups, respectively. There was no significant difference in treatment compliance among the groups. CONCLUSIONS The present phase II study suggests that mouth washing with rebamipide may be effective and safe for patients with HNC receiving chemoradiotherapy, and 4% liquid is the optimal dose of rebamipide.

Abstract
As an index of lipid peroxidation (LPO), levels of thiobarbituric acid (TBA)-reactive substances were examined in the kidneys of male F344 rats, BDF1, CDF1, and B6C3F1 mice, and Syrian golden hamsters after a single intravenous (IV) administration of potassium bromate (KBrO3) at various doses. In the rats, LPO levels were significantly increased in both a dose-dependent and time-dependent manner. However, when the rats were given intraperitoneal (IP) injection of cysteine, the levels of LPO were not significantly different between KBrO3-treated animals and controls. In CDF1 mice, the slight increases in LPO levels observed were much weaker and not statistically significant. On the other hand, treatment of BDF1 and B6C3F1 mice or hamsters with KBrO3 resulted in decreased values as compared to controls. The effect of treatment with cysteine, glutathione (GSH), or diethyl maleate (DEM) on mortality was tested in male F344 rats given IV injection of KBrO3 at various doses. Significant reduction and elevation in the mortality were observed in rats treated with cysteine or GSH and DEM, respectively. Significant dose-dependent and time-dependent increases were observed in the levels of serum non-protein nitrogen (NPN), blood urea nitrogen (BUN), and creatinine, and absolute and relative weight of the kidneys in male F344 rats administered KBrO3 IV. Microscopically, the appearance of numerous eosinophilic droplets in the cytoplasm of proximal tubular epithelium of KBrO3-treated rats was noteworthy. All these changes were reduced and exacerbated by treatment with cysteine or GSH and DEM, respectively. The possibility of LPO formation in the kidney by active oxygen radicals generated by KBrO3 is suggested. A possible relationship between LPO levels in the kidney and species differences in the renal toxicity and carcinogenicity of KBrO3 is implicated.

Abstract
An accurate and selective analytical method for amantadine, which is used as antiviral drug to treat influenza A virus infection, was developed using LC-MS/MS. Residual amantadine was extracted from 4 kinds of food sample (poultry muscle, liver, gizzard and egg) with acetonitrile-pH 3.0 McIlvaine buffer (7 : 3), then cleaned up with an Oasis® MCX mini-cartridge. An external standard calibration curve was used for quantification, after sample purification by the combination of a reverse-phase strong cation exchange mixed mode cartridge for cleanup and a HILIC column for HPLC. The method was validated by performing recovery tests in accordance with Japanese guidelines for the validation of analytical methods for residual agricultural chemicals in food. Recovery ranged from 79.3% to 91.7%, RSDs of repeatability were under 3.3%, and RSDs of within-laboratory reproducibility were under 8.4%. This new method was applied to samples of poultry and egg purehased in Tokyo, but residual amantadine was not detected at all.

Abstract
A novel GII.P17-GII.17 variant norovirus emerged as a major cause of norovirus outbreaks from December 2014 to March 2015 in Japan. Named Hu/GII/JP/2014/GII.P17-GII.17, this variant has a newly identified GII.P17 type RNA-dependent RNA polymerase, while the capsid sequence displays amino acid substitutions around histo-blood group antigen (HBGA) binding sites. Several variants caused by mutations in the capsid region have previously been observed in the GII.4 genotype. Monitoring the GII.17 variant's geographical spread and evolution is important.

Abstract
A new concept in chromatography is proposed that utilizes a temperature-responsive surface with a constant aqueous mobile phase. The surface of the silica stationary phase in high-performance liquid chromatography (HPLC) has been modified with temperature-responsive polymers to exhibit temperature-controlled hydrophilic/hydrophobic changes. Poly(N-isopropylacrylamide) (PIPAAm) was grafted onto (aminopropyl)silica using an activated ester-amine coupling method. These grafted silica surfaces show hydrophilic properties at lower temperatures which, as temperature increases, transform to hydrophobic surface properties. The elution profile of five mixed steroids on an HPLC column packed with this material depends largely on the temperature of the aqueous mobile phase. Retention times increase with increasing temperature without any change in the eluent. Changes in the retention times of hydrophobic steroids were larger than those for hydrophilic steroids. The temperature-responsive interaction between PIPAAm-modified silica and these steroids is proposed to result from changes in the surface properties of the HPLC stationary phase by the transition of hydrophilic/hydrophobic surface-grafted IPAAm polymers. We demonstrate a novel and useful new chromatography system in which surface properties and the resulting function of the HPLC stationary phase are controlled by external temperature changes. This method should be effective in biological and biomedical separations of peptides and proteins using only aqueous mobile phases.

Nano-sized domains of this cation-ordered phase appear alongside disordered regions; domain size increases from 2 to 8 nm with increasing Li content. Compositions of ordered and disordered regions are Li- and Co-rich, respectively, and, therefore, the phase exhibits frozen-in, incipient phase separation. This microstructure could be considered as a precursor to precipitation of fully ordered, rhombohedral LiCoO

Abstract
BACKGROUND AND HYPOTHESIS Brachial artery flow-mediated dilation (FMD), a noninvasive, widely used clinical index of endothelial function and magnitude of FMD, has been reported to be closely related to many coronary risk factors and coronary atherosclerosis. However, there has been no study that examines the diurnal change of FMD. We designed this study to reveal the diurnal variation of FMD in healthy volunteers. METHODS We examined FMD in response to reactive hyperemia by high resolution ultrasound in 13 healthy young men (age 25-32) at four different times over the course of a day. RESULTS Mean measures of brachial artery FMD was 4.0% at 8:00, 5.3% at 12:00, 9.7% at 17:00, and 6.9% at 21:00 hours. Flow-mediated dilation at 8:00 and at 12:00 hours was significantly lower than that at 17:00 (p < 0.05). CONCLUSIONS These results show that endothelial function has diurnal variation and is significantly attenuated in the morning. Morning attenuation of endothelial function should be recognized in clinical research and may play an important role in the circadian variation of the occurrence of acute cardiovascular events.

Abstract
BACKGROUND The optimum management of patients with moyamoya disease remains controversial. OBJECTIVES To examine retrospectively the correlation between the degree of haemodynamic stress and the clinical presentation by measuring cerebral haemodynamics and metabolism using positron emission tomography (PET). METHODS 57 patients with moyamoya disease (mean age 32 years, range 12 to 64), classified into five groups according to clinical manifestations, underwent PET measurement of cerebral blood flow (CBF), cerebral blood volume (CBV), cerebral metabolic rate for oxygen (CMR(O2)), and oxygen extraction fraction (OEF) using (15)O labelled gases. The regional values in patient groups were compared with a normal group. RESULTS CBF in non-symptomatic patients, patients presenting with transient ischaemic attacks (TIA), and patients with haemorrhagic onset (H) was not significantly lower than in normal controls in any region. CBV in the TIA group and in patients with infarction associated with TIA (I/TIA) was significantly higher than in the controls in most regions. OEF in the frontal, parietal, and temporal cortex was significantly higher in the I/TIA group than in the controls. Patients in the H group and those with a permanent deficit with infarction (PD group) had decreased metabolism with normal OEF. Multivariate analysis to test the distribution of the three dimensional vector (CBF, CBV, OEF) showed significant differences between every possible pair among the six groups except NS v H and H v PD in the frontal cortex. CONCLUSIONS The haemodynamic status of moyamoya disease is not uniform, and severe haemodynamic stress occurs in selected subgroups of patients.

For this report, in a group of 73 patients with ovarian adenocarcinomas, clinical factors and protein expression status of p53, retinoblastoma (Rb), and related proteins were evaluated for potential prognostic values. Clinical factors included FIGO stage, age, histopathologic type, and protein expression of p53, Rb, MDM2, p14ARF, p21WAF(1)/CIP(1) was determined by an immunohistochemical technique. Univariate Cox proportional hazard regression analysis was used to determine the significant prognostic value of FIGO stage (P < 0.0001), p53 status (0.0021), and patient age (P = 0.0255), and we report here, for the first time, the significant (P = 0.0072) prognostic value of Rb status. Histopathologic type and MDM2, p14ARF, p21WAF(1)/CIP(1) status did not show any prognostic value. To examine further the independence of prognostic values, we next applied multivariate analysis: We found that FIGO stage (P < 0.0001) and p53 status (P = 0.0108) were independent prognostic factors, while age and Rb status were not. Independence of prognostic value of p53 has heretofore been controversial, but we found a definite independent prognostic value for p53 status in ovarian adenocarcinomas. We also found that selection of appropriate antibodies for immunohistochemistry was essential to obtain significant results. We used five kinds of antibodies for p53 immunolocalization, and correlation with prognosis was obtained by three of these with different grades of statistical significance.

Abstract
BACKGROUND AND AIM Long term Helicobacter pylori infection leads to atrophic gastritis but the relation between H pylori infection and autoimmune related atrophic gastritis (AIG) remains unclear. We studied the effects of H pylori infection on the pathophysiology of AIG in mice. MATERIALS AND METHODS BALB/c nu/nu mice (n=40) with or without H pylori infection received splenocytes from neonatally thymectomised mice to induce AIG. Half of the mice were orally infected with H pylori prior to AIG induction. Histological findings, and local and systemic immune responses were serially evaluated. RESULTS Two and six months after transfer, parietal cells in uninfected mice were depleted while those in infected mice were well preserved. The degree of gland atrophy (p<0.01), hyperplasia (p<0.01), gastric pH (p<0.05), and serum gastrin levels of infected mice were significantly lower than those of uninfected mice. Serum antiparietal cell antibody levels gradually decreased in infected mice, and were significantly lower than those of uninfected mice at six months (p<0.05). Real time polymerase chain reaction studies revealed significantly higher interleukin 4 (p<0.05) and transforming growth factor beta (p<0.05) gene expression in the gastric mucosa in infected mice than in uninfected mice at both two and six months after AIG induction. CONCLUSIONS H pylori infection inhibited the development of AIG in mice. Th2-type immune responses and transforming growth factor beta in the gastric microenvironment might be involved in the inhibitory effects of H pylori infection on the development of AIG, in which Th1-type responses have an important role.

Abstract
Spontaneously hyperlipidemic (SHL) mice are Japanese wild mice (KOR) with disruption of the apolipoprotein E (Apo E) gene. These mice (KOR-Apoe(shl)) are superhypercholesterolemic and develop severe xanthoma, but their atherosclerosis is relatively mild compared with Apo E knockout mice. First, we tested whether this distinction is due to additional mutation of the Apoc1 and/or Apoc2 genes in KOR-Apoe(shl). Southern blot analysis, but found no gross disruption of these genes. Next, we tested whether the phenotypic distinction is due to differences in the genetic background. To this end, we established three lines of congenic SHL mice with a genetic background of C57BL/6, BALB/c or C3H/He, and named them, respectively, C57BL/6.KOR-Apoe(shl) (B6.KOR-Apoe(shl)), BALB/c.KOR-Apoe(shl) (C.KOR-Apoe(shl)) and C3H/He.KOR-Apoe(shl) (C3.KOR-Apoe(shl)). Hypercholesterolemia was most severe in KOR-Apoe(shl) followed the by others as follows; KOR-Apoe(shl)>>C3.KOR-Apoe(shl)>C.KOR-Apoe(shl)>B6.KOR-Apoe(shl). In contrast, atherosclerosis was most severe in B6.KOR Apoe(shl) followed by the others: B6.KOR-Apoe(shl)>C.KOR-Apoe(shl)>>C3.KOR-Apoe(shl)> or =KOR-Apoe(shl). This order, however, did not match that in xanthoma, which was highly prominent in KOR-Apoe(shl) but mild in B6.KOR-Apoe(shl), C.KOR-Apoe(shl) and C3.KORApoe(shl). This order, however, did not match that in xanthoma, which was highly prominant in KOR-Apoe(shl) but mild in B6.KOR-Apoe(shl), C.KOR-Apoe(shl) and C3.KOR-Apoe(shl). These distinctions suggest that the severity of each of the phenotypes is determined by distinct genetic backgrounds which probably are composed of polymorphism of lipid metabolism-related proteins. We found that apolipoprotein A-I is decreased in each SHL strain and polymorphic between B6.KOR-Apoe(shl) and the other strains examined. This polymorphism may be related to the most severe atherosclerosis observed in B6.KOR-Apoe(shl). It is most likely that combination of such polymorphisms is due to the genetic background accountable for phenotype distinctions.

Abstract
Postpolio syndrome (PPS) is generally defined as a clinical syndrome of new weakness, fatigue, and pain in individuals who have previously recovered from acute paralytic poliomyelitis. These new problems may lead to loss of employment as well as new deficits in instrumental activities in daily living (cleaning, washing, shopping, transportation, etc.), walking, climbing stairs, and personal assistance. We presented three cases of PPS with working disabilities in Japan, and stated the issues confronted with. Particularly at the workplace, PPS individuals need special supports from both rehabilitation medicine and occupational health services, including improved nutrition, achieving ideal body weight, regular and sensible exercise, frequent checkups, and modifying working conditions.

Abstract
We investigated the outcome after patients with traumatic brain injury (TBI) were treated in our hospital. Subjects were 51 patients with TBI (43 men, 8 women; mean age 34.9 +/- 20.3 yr), who had been admitted to the department of rehabilitation in our hospital between 1980 and 2000. Data were collected retrospectively from the medical records. Most injuries were due to motor vehicle accidents. The percentage of patients who suffered impaired cognitive and behavioral functions was 86.3%. The percentage of patients who were discharged to their homes was 70.6%, but none of them could return to work. Patients who were severely disabled in their daily activities or had cognitive and behavioral disturbances were difficult to discharge. We need to establish a comprehensive rehabilitation approach to cognitive and behavioral disturbances for patients with TBI.

Abstract
OBJECTIVE To explore the association between multi-dimensional aspects of hostility and coronary heart disease among middle-aged urban Japanese. SUBJECTS AND METHODS We conducted a case-control study. Cases were consecutive patients with acute coronary syndrome admitted to a hospital in Japan. Fifty-three patients (45 men and 8 women) aged 35 to 65 were enrolled. For each case, two sex and age (+/-2 years) matched controls were recruited from among participants in a health check-up program at a health promotion center located in the same area as the hospital. Two questionnaires, both with four components, were used to measure hostility and coping with anger: the one was for anger, hostility, physical aggression and verbal aggression, and the other for aggression, social inhibition, guilt, and controlled affect. RESULTS The scores of all components from two questionnaires were higher for cases than controls, but the differences were not significant. Multivariate analysis showed that anger, fat intake, alcohol consumption and house size were significantly associated with the etiology of acute coronary syndrome. CONCLUSION Anger, lifestyle, and socioeconomic status play important roles for the etiology of coronary heart disease in middle-aged urban Japanese.

Abstract
Acrylic oligomers such as pentaerythritolacrylates (PEA), which are often utilized in the field of functionalized materials, generally consist of very complex homologous series. In this work, measuring conditions for packed-column supercritical fluid chromatographic separation of a complex PEA sample manufactured industrially were systematically examined using temperature programming or modifier gradient technique. Under the conditions thus optimized, not only the main components, PEA homologues containing different number of acryloyl groups, but also trace constituents such as their by-products formed through Michael addition reactions were favorably resolved on the resulting chromatograms. The fact that the coefficient of variation (CV) for relative intensity of each peak was approximately 3-6% even for the minor components suggested that detailed compositional analysis of PEAs could be performed precisely by the proposed method.

Abstract
Immunological interaction between the host and Helicobacter pylori seems to play a critical role in follicular formation in gastric mucosa. We reported H. pylori-induced follicular gastritis model using neonatally thymectomized mice. In this study, we investigated the involvement of various cytokines in this model. BALB/c mice were thymectomized on the third day after birth (nTx). At 6 weeks old, these mice were orally infected with H. pylori. Histological studies showed that follicular formation occurred from 8 weeks after the infection and that most of the infiltrating lymphocytes were CD4(+) and B cells. Neutrophils increased transiently at 1 week after the infection. Gamma interferon, interleukin-7 (IL-7), and IL-7 receptor were expressed in the stomach of the nTx mice irrespective of the infection. In contrast, expressions of the tumor necrosis factor alpha, IL-4 and lymphotoxin-alpha genes were remarkably upregulated by the infection. Our findings suggest that follicular formation may require cooperative involvement of a Th2-type immune response, tumor necrosis factor alpha and lymphotoxin-alpha in addition to the Th1-type immune response in H. pylori-induced gastritis in nTx mice.
