Abstract
BACKGROUND & AIMS Some ω3 polyunsaturated fatty acids (PUFAs) are said to demonstrate a dose-related risk of atrial fibrillation (AF), conversely, some ω6 PUFAs might have AF protective potential. However, few investigated the relation among ischemic strokes. Primarily, we aimed to examine a relation between ω3 and ω6 PUFAs and the presence of AF in ischemic strokes. Further, since, some PUFAs are said to affect the cardiac load, we secondarily aimed to investigate the association between ω3 and ω6 PUFAs and brain natriuretic peptide (BNP) and the occurrence of cerebral large vessel occlusion (LVO) in ischemic strokes with AF. METHODS Consecutive patients with ischemic stroke admitted between 2012 and 2022 were retrospectively screened. Plasma levels of PUFAs, including eicosapentaenoic acid (EPA), docosahexaenoic acid, dihomo-γ-linolenic acid (DGLA) and arachidonic acid (AA), were assayed. Data were analyzed using a Poisson regression analysis with a robust variance estimator and a multiple linear regression analysis. RESULTS We screened 2112 consecutive ischemic strokes, including 1574 (1119 [71%] males, median age 69 years). Lower DGLA (prevalence ratio (PR) 0.885, 95% CI 0.811-0.966, p = 0.006), lower AA (PR 0.797, 95% CI 0.649-0.978, p = 0.030), and higher EPA/AA ratio (PR 1.353, 95% CI 1.036-1.767, p = 0.026) were associated with AF. Checking the linearity between AF and PUFAs, negative linear trends were observed between DGLA quartiles (Q1: PR 1.901, Q2: PR 1.550, Q3: PR 1.423, Q4: 1.000, p < 0.001 for trend) and AA quartiles (Q1: PR 1.499, Q2: PR 1.204, Q3: PR 1.125, Q4: 1.000, p = 0.004 for trend), with positive linear trends between EPA/AA ratio quartiles (Q1: 1.000, Q2: PR 1.555, Q3: PR 1.612, Q4: PR 1.797, p = 0.001 for trend). Among patients with AF, a negative association between AA and BNP (unstandardized coefficient -1.316, 95% CI -2.290∼-0.342, p = 0.008) was observed, and lower AA was associated with LVO (PR 0.707, 95% CI 0.527-0.950, p = 0.021). CONCLUSION Lower DGLA and AA and a higher EPA/AA ratio might be related to the development of AF in ischemic strokes. Further, AA might have a cardio-cerebrovascular protective role in ischemic strokes with AF.

Abstract
BACKGROUND AND AIMS Small ischemic lesions (SILs) accompanying intracerebral hemorrhage (ICH) might be induced by small-vessel vulnerability and hypercoagulation. Some polyunsaturated fatty acids (PUFAs) have been associated with hypercoagulation in cardiovascular diseases. Our aim here is to determine how pre-existing small-vessel disease (SVD) and PUFAs may affect SILs. METHODS AND RESULTS We screened consecutive ICH patients (October 2012-December 2021) meeting two inclusion criteria: (1) the patients were hospitalized for acute ICH and were undergoing magnetic resonance imaging and (2) the patients' PUFA measurements were available. After excluding patients with isolated intraventricular hemorrhage, we evaluated whether three SVD markers (white matter hyperintensities, old lacunes, cerebral microbleeds) and PUFAs might be associated with the development of SILs. We selected 319 participants from 377 screened consecutive ICH patients (median age = 64, males = 207 [65 %]). Of the 319 patients, 45 patients (14 %) developed SILs. In a multivariable logistic regression analysis, the factors associated with SILs were old lacunes (OR 3.255, 95 % CI 1.101-9.622, p = 0.033) and DHA/AA ratio (OR 0.180, 95 % CI 0.046-0.704, p = 0.013). Furthermore, in our multivariable analysis using DHA/AA ratio tertiles with and without SILs, we observed a linear trend between SILs and the Higher Tertile of the DHA/AA ratio (DHA/AA ratio Mid-Tertile: OR 1.330, 95%CI 0.557-3.177, p = 0.521, and DHA/AA ratio Lower Tertile: OR 2.632, 95%CI 1.124-6.162, p = 0.026). CONCLUSION The presence of old lacunes and lower DHA/AA ratios might be associated with SILs accompanying ICH.

Abstract
BACKGROUND AND OBJECTIVE This study's objective is to investigate whether mild aortic arch plaque is associated with the development of atrial fibrillation (AF) in stroke patients with embolic stroke of undetermined source (ESUS) during the first year following the implantation of an insertable cardiac monitor (ICM). METHODS The participants in this cross-sectional observational study were consecutive patients with ESUS, even after transesophageal echocardiography. We assessed the relationship between the thickness of the participants' aortic arch plaque and AF detected after ICM implantation. RESULTS Of the 50 consecutive patients with ESUS enrolled in this study, 12 (24%) developed AF. We observed that thicker aortic arch plaque was associated with undetected AF (2.3 mm vs. 1.2 mm, p < 0.001). Aortic arch plaque thickness was independent associated with undetected AF (OR 54.00, 95% CI 2.706-1077.544, p = 0.009). When the cut-off value for aortic arch plaque thickness was 1.8 mm, the sensitivity and specificity were 71.1% and 91.7%, respectively (95% CI = 0.75-0.98, p < 0.001). Also, patients having both aortic arch plaque with a thickness < 1.8 mm and a CHADS2 score ≥ 4 were more likely to have detectable AF than no AF (88% vs. 12%, p < 0.001). CONCLUSION A thinner aortic arch plaque was associated with the development of AF. Patients with mild aortic plaques below 4 mm but ≥1.8 mm in thickness and without other high-risk features are less likely to have paroxysmal AF on ICM, and these plaques may be a possible source of embolism for their strokes.

Abstract
AIMS Urinary immunoglobulin G (IgG) may be a stronger marker of atherosclerosis than microalbuminuria are because urinary IgG reflects proteinuria level and size-selectivity loss. Microalbuminuria-not urinary IgG-is associated with mild acute ischemic stroke (MAIS). METHODS Using the Jikei University School of Medicine Stroke Registry, we selected and screened patients with symptomatic acute ischemic stroke (onset-to-door time ≤ 24 h). The exclusion criteria were (1) on-admission NIHSS scores >10, (2) a modified Rankin Scale (mRS) score ≥ 2 prior to stroke onset, (3) incomplete data (no urinalysis ≤ 3 days after admission or no mRS score at 90 days from stroke onset), and (4) an active malignancy. Patients at 90 days post-discharge were divided into those with favorable mRS scores of 0-1 and those with unfavorable mRS scores of 2-6. Clinical backgrounds were compared for (1) patients with positive and negative urinary IgG results, and (2) patients with favorable and unfavorable outcomes. RESULTS Of our study's 210 patients (164=male, median age=68, median eGFR=53.2 ml/min/1.73 m2), 30 (14%) presented with positive urinary IgG, which was associated with cardiovascular risk factors. Higher BNP, higher D-dimer, lower eGFR, and higher CAVI were associated with higher positive urinary IgG. The favorable group, comprising 155 (74%) patients, had higher negative urinary IgG than the unfavorable group (89% vs 76%, P=0.026). No statistical difference emerged regarding microalbuminuria (29% vs 29%, P=1.000). CONCLUSION In MAIS, urinary IgG was associated with both the presence of atherosclerosis and an unfavorable outcome at 90 days after stroke onset.

Abstract
BACKGROUND AND AIMS Circadian variability of blood pressure (BP) and hypercoagulation in the morning have been proposed as underlying mechanisms of wake-up stroke (WUS). The aim was to determine the impact of cerebral microbleeds (CMBs), showing BP fluctuation and background hypercoagulability, on WUS. METHODS Consecutive patients with acute ischemic stroke onset-to-door time within one week were screened. WUS was defined as an ischemic stroke that occurred during sleep at night. CMBs were categorized into three: "strictly Lobar", "strictly Deep (D) and/or Infratentorial (I)", and "Mixed". Moderate to severe CMBs were defined as having more than three in total. First, whether CMBs are associated with WUS was examined. Second, the same analysis was performed according to the stroke subtype classified as large-artery atherosclerosis (LAA), cardioembolism (CE), and small-vessel occlusion (SVO). RESULTS A total of 1477 patients (1059 [72%] male, median age 69 years) were included, and WUS was observed in 363 (25%) patients. On Poisson regression analysis with a robust variance estimator in the total cohort, moderate to severe strictly D and/or I CMBs (PR 1.505, 95% CI 1.154-1.962, p = 0.003) were associated with WUS. From the perspective of stroke subtype, the same result was confirmed in LAA (PR 2.223, 95% CI 1.036-4.768, p = 0.040) and CE (PR 1.668, 95% CI 1.027-2.709, p = 0.039), not SVO. CONCLUSIONS The presence of moderate to severe strictly D and/or I CMBs might be associated with the development of WUS. By stroke subtype, the same result was confirmed in LAA and CE.

Abstract
BACKGROUND Low arachidonic acid (AA) levels are reportedly associated with unfavorable outcomes in intracerebral hemorrhage (ICH). OBJECTIVE We aimed to clarify whether serum AA levels might be associated with a good recovery from severe motor paralysis in the early stage of hospitalization. METHODS From among consecutive ICH patients between October 2012 and December 2021, patients with a sum of upper and lower extremity National Institutes of Health stroke scale (NIHSS) scores of 4-8 at admission (severe motor paralysis) were included. We defined good early recovery from severe motor paralysis as a sum of upper and lower extremity NIHSS scores of 0-3 on day 7 after admission, and that of individual upper and lower extremities as NIHSS scores of 0-1 on day 7 after admission. We aimed to assess whether serum AA levels might be associated with good early recovery from severe motor paralysis. RESULTS We screened 377 consecutive ICH patients, including 140 with severe motor paralysis (88 (63%) males, median age 64 years). Recovery from severe motor paralysis was seen in 48 (34%). Higher AA levels (PR 1.243, 95% CI 1.042 to 1.483, p = 0.016) were independently associated with good overall recovery, and good recovery of upper and lower extremities separately (upper extremity: PR 1.319, 95% CI 1.101 to 1.580, p = 0.003; lower extremity: PR 1.293, 95% CI 1.115 to 1.499, p = 0.001). CONCLUSIONS Higher AA levels may contribute to a good early motor recovery in patients with severe motor paralysis due to ICH.

Abstract
BACKGROUND Orthostatic hypotension (OH) is a potential modifiable risk factor for cognitive impairment in patients with Parkinson's disease (PD). Although other risk factors for dementia, hyposmia and REM sleep behavior disorder (RBD), are closely associated with autonomic dysfunction in PD, little is known about how these risk factors influence cognitive function and cerebral pathology. OBJECTIVE We investigated how these three factors contribute to gray matter atrophy by considering the interaction of OH with hyposmia and RBD. METHODS We analyzed cortical thickness, subcortical gray matter volume, and cognitive measures from 78 patients with de novo PD who underwent the head-up tilt test for the diagnosis of OH. RESULTS Whole-brain analyses with Monte Carlo corrections revealed that hyposmia was associated with decreased cortical thickness in a marginal branch of the cingulate sulcus among patients with OH, and cortical thickness in this area correlated with cognitive functioning only in patients with OH. Subcortical gray matter volume analysis indicated that severe RBD was associated with decreased volume in the left hippocampus and bilateral amygdala among patients with OH. CONCLUSION Even in early PD, OH exerts effects on gray matter atrophy and cognitive dysfunction by interacting with RBD and hyposmia. OH might exacerbate cerebral pathology induced by hyposmia or RBD.

Abstract
Background:
Liver fibrosis (LF) is reported to affect the development of cerebral small vessel disease (SVDs) including cerebral microbleeds (CMBs). The Fibrosis-4 (Fib4) index is a simple and non-invasive scoring method for detecting LF. Herein, we investigated the association between the severity of LF and the presence or distribution of CMBs.
Methods:
From October 2012 to May 2022, patients with acute ischemic stroke within 24 hours from onset were retrospectively enrolled. Exclusion criteria were those associated with malignancy or missing clinical data including MRI findings before treatment started, or functional outcome at 3 months after discharge. The distribution of CMBs were classified on MRI as strictly lobar, or not (deep/ infratentorial or mixed area). FIB-4 index is calculated as follows: FIB-4 = [age (years)*aspartate aminotransferase (U/L)] / [platelet count (10
9
/L) *√alanine aminotransferase (U/L)]. We analyzed the association between the severity of LF, according to the tertile of Fib4 index; mild-LF (Fib4 index < 1.30), moderate-LF (1.30 ≤ Fib4 index < 2.67), severe-LF (2.67 ≤ Fib4 index), and the presence and distribution of CMBs.
Results:
614 subjects (median age 69 years, 435 men) were retrospectively enrolled. Fib4 index were higher in order of only lobar, deep/ infratentorial or mixed area, and none CMBs (
p
< 0.001). Also, severe LF group showed the highest number of CMBs (p < 0.001). Age on admission (OR 1.040, 95% CI 1.020-1.050, p < 0.001), hypertension (OR 1.840, 95%CI 1.260-2.690,
p
= 0.002), and anti-thrombotic drugs using (OR 1.500, 95% CI 1.020-2.190,
p
= 0.038) were independently associated with the presence of CMBs. In anatomical distribution of CMBs, Fib4 index (OR 0.701, 95%CI 0.505-0.974, p = 0.034) were only independent predictive factor of the CMBs on D/I or mixed area.
Conclusion:
The novel association between silent LF and the distribution of CMBs as located in only lobar were established.

Abstract
Background and Purpose:
Blood viscosity (BV) is associated with blood stagnation leading to thrombosis. Some polyunsaturated fatty acids (PUFAs) are said to have an antithrombotic effect. First, we aimed to determine the association between BV and the presence of the susceptivity vessel sign (SVS) in patients with cardioembolism (CE) due to atrial fibrillation (AF). Second, we aimed to reveal the association between BV and PUFAs levels.
Methods:
Consecutive patients with ischemic stroke who met the following inclusion criteria were included: 1) patients with CE, defined by TOAST classification, secondary to AF; 2) onset to door time within 24 h; 3) availability of MRI, including susceptibility-weighted images, obtained at our hospital before IV rt-PA and/or MT; and 4) availability of PUFAs measurements on the day of or the day after the hospital visit. Hematocrit-derived BV at high shear rate (300 sec
-1
) was calculated using the following formula: BV = 1.4175+ 5.878*Ht - 12.98*Ht
2
+ 31.964*Ht
3
(Ht = Hematocrit/100). First, we assessed whether BV could be associated with the presence of SVS. Second, we evaluated whether some PUFAs (dihomo-γ-linolenic acid [DGLA], arachidonic acid, eicosapentaenoic acid, docosahexaenoic acid) levels could be the factors associated with BV.
Results:
We screened 1,720 consecutive ischemic stroke patients and included 137 patients (95 [69%] male, median age 73 years). Of 137, SVS was observed in 83 (61%) patients. In multivariable logistic regression analysis, BV was independently associated with the presence of SVS (odds ratio [OR] 0.391, 95% confidence interval [CI] 0.18-0.86,
p
= 0.02, Figure). Multiple linear regression analysis revealed a significant positive association between DGLA levels and BV (unstandardized coefficient 0.01, 95% confidence interval 0.01 to 0.02,
p
< 0.01).
Conclusions:
Lower BV might be related to the presence of SVS with CE due to AF and DGLA level might be positively associated with BV.

Abstract
Background and Purpose:
Ischemic stroke developed while bathing (ISB) occasionally causes fatal accident. Factors associated with ISB remain unclear. We aimed to estimate the clinical characteristics of ISB, especially the subtype of stroke and the association between cerebral small vessel disease (CSVD) markers.
Methods:
Consecutive patients with ischemic stroke ≤48 h from onset who underwent MRI during the hospitalization were included. We divided patients into ISB and non-ISB group to analyze differences in clinical characteristics, especially the stroke subtype based on TOAST classification and the association between CSVD markers. The CSVD markers were evaluated by MRI and defined as old lacunes, white matter hyperintensities scale (separately scored by periventricular hyperintensity [PVH] and deep and subcortical white matter hyperintensity), the number of cerebral microbleeds (CMBs) categorized as lobar, deep, and infratentorial lesions, and the scale of enlarged perivascular space in the basal ganglia and centrum semiovale.
Results:
We screened 2,112 consecutive patients with ischemic stroke including 1,517 patients (1,070 [71%] male, median age 69 years). Of these patients, 52 (3%) were included in ISB group. In univariable analysis, ISB group showed higher frequency of large-artery atherosclerosis (
p
= 0.004), lower frequency of cardioembolism (
p
= 0.008), smaller number of cerebral microbleeds in deep lesions (
p
= 0.025) and lower grade of PVH (
p
= 0.023). ISB group showed a lower NIHSS score on admission (
p
= 0.002). However, there was no difference in mRS score at 3 months from the onset. In the multivariable analysis (Figure), large-artery atherosclerosis (OR 2.46, 95% CI 1.21-5.01,
p
= 0.013) and CMBs in deep lesions (OR 0.75, 95% CI 0.58-0.98,
p
= 0.038) showed independently associated with ISB.
Conclusions:
ISB showed higher frequency of large-artery atherosclerosis, however, had a less association with the presence of CMBs in deep lesions.

Abstract
OBJECTIVE To determine the impact of old lacunes and their sites on the prognosis of one-sided supratentorial intracerebral hemorrhage (ICH) by classifying lacunes sites in relation to anatomical structures using MRI. METHODS Consecutive patients with one-sided supratentorial ICH ≤72 h from onset to door who underwent MRI were retrospectively included. The sites of old lacunes were categorized as follows: deep subcortical white matter, caudate head, lentiform, posterior limb and genu of the internal capsule, thalamus, and brainstem. We also evaluated all other cerebral small vessel disease markers. An unfavorable outcome was defined as a modified Rankin Scale score of 3 to 6 at 3 months after onset. We investigated whether old lacunes in particular locations were related to unfavorable outcomes. RESULTS We included 186 patients with one-sided supratentorial ICH (126 [68%] males, median age 62 years). Of 186 patients, 65 (35%) patients had unfavorable outcomes. Factors associated with unfavorable outcomes were age (OR 2.261, 95% CI 1.332-3.839, p = 0.003), National Institutes of Health Stroke Scale [NIHSS] score at admission (OR 1.175, 95% CI 1.090-1.267, p < 0.001), and old thalamic lacunes contralateral to the hematoma (OR 3.805, 95% CI 1.009-14.340, p = 0.048). Patients with old thalamic lacunes contralateral to the hematoma tended to have arm (p = 0.006) and leg (p = 0.011) motor impairment on the paralyzed side at discharge as estimated by the NIHSS score. CONCLUSIONS Old thalamic lacunes contralateral to the hematoma may be related to unfavorable outcomes in ICH.

Abstract
Our meta-epidemiological study aimed to describe the prevalence of reporting effect modification only on relative scale outcomes and inappropriate interpretations of the coefficient of interaction terms in nonlinear models on categorical outcomes. Our study targeted articles published in the top 10 high-impact-factor journals between 1 January and 31 December 2021. We included two-arm, parallel-group, interventional superiority randomized controlled trials to evaluate the effects of modifications on categorical outcomes. The primary outcomes were the prevalence of reporting effect modifications only on relative scale outcomes and that of inappropriately interpreting the coefficient of interaction terms in nonlinear models on categorical outcomes. We included 52 articles, of which 41 (79%) used nonlinear regression to evaluate effect modifications. At least 45/52 articles (87%) reported effect modifications based only on relative scale outcomes, and at least 39/41 (95%) articles inappropriately interpreted the coefficient of interaction terms merely as indices of effect modifications. The quality of the evaluations of effect modifications in nonlinear models on categorical outcomes was relatively low, even in randomized controlled trials published in medical journals with high impact factors. Researchers should report effect modifications of both absolute and relative scale outcomes and avoid interpreting the coefficient of interaction terms in nonlinear regression analyses.

Abstract
Background:
Lacunar infarct (LI) is a heterogeneous disorder of cerebral small vessel. Hierarchical clustering (HC) is useful for exploring potential underlying clinical phenotype in heterogeneous disease. Our aim is to identify the predictive factors of poor functional outcome in LI to classify the subjects into distinct subgroups using HC and compare the clinical variables including clinical outcome among groups.
Methods:
From October 2012 to April 2020, LI patients within 24 hours from the onset were enrolled. We used a HC k-means clustering algorithm on patients’ baseline data. We also compared clinical outcome among each cluster groups.
Results:
Among 187 patients (144 male, median age 66 years old, median NIHSS score2), three clusters were identified. Cluster1(58%), mostly comprised of younger patients (p<0.01), had fewer past history of ischemic stroke (p=0.007). The severity of deep subcortical white matter hyperintensity (DSWMH) and periventricular hyperintensity (PVH) were mild, and small number of cerebral microbleeds (MBs) are detected (p<0.001 for each). Cluster2(15%), mostly comprised of older patients (p<0.001), had the highest NIHSS score on admission (p=0.021). Serum D-dimer and Cr levels were relatively higher (p<0.001, p=0.003, respectively). Cluster3(28%), mostly comprised of men, represented the highest number of MBs (p<0.001) and increase of mean IMT (p =0.003). Poor functional outcome defined as mRS at 3 months > 2-6 was 4% of cluster1, 100% of cluster 2 and 12% of cluster 3 (p=0.001). In multivariate logistic regression analysis, the phenotype of cluster was the strongest predictor of poor functional outcome (OR 16.1, 95% CI 6.04-42.9, p<0.001, Figure).
Conclusion:
Three clusters with different clinical outcome were identified. The phenotype of cluster was the strongest predictive factor of poor functional outcome. Further study to identify whether management of these components provide different clinical outcome was warranted.

Abstract
Background and Purpose:
To determine the association between the markers of cerebral small vessel disease (CSVD) and cerebral brain atrophy evaluated by magnetic resonance imaging (MRI) and outcomes after intracerebral hemorrhage (ICH).
Methods:
Consecutive patients with ICH ≤72 h from onset to door who underwent MRI during the hospitalization were included. We evaluated the CSVD markers as white matter hyperintensities scale (separately scored by periventricular hyperintensity [PVH] and deep and subcortical white matter hyperintensity [DSWMH]), the number of cerebral microbleeds, the number of old lacunes, and enlarged perivascular spaces scale and the degree of cerebral brain atrophy as global cortical atrophy scale. An unfavorable outcome was defined as a modified Rankin Scale score of 3 to 6 at 3 months from onset. We evaluated whether markers of CSVD and cerebral brain atrophy all assessed by MRI could be associated with prognosis of ICH.
Results:
We screened 361 consecutive patients with ICH, including 231 patients (161 [70%] male, median age 62 years). Of 231 patients, 83 (36%) patients had unfavorable outcomes. PVH, not DSWMH, was independently associated with unfavorable outcomes (odds ratio 2.059, 95% confidence interval 1.029-4.120,
p
= 0.041, Figure). There were no significant relationships between other CSVD markers and cerebral brain atrophy and prognosis after ICH.
Conclusions:
Severe PVH on MRI might predict unfavorable outcomes after ICH.

Abstract
A 51-year-old Japanese man who experienced colon cancer recurrence following primary and metastatic lesion resection was hospitalized due to facial cellulitis with febrile neutropenia and purpura on his lower extremities after chemotherapy. It was complicated by rapidly progressive glomerulonephritis. He was diagnosed with immunoglobulin A (IgA)-dominant endocapillary proliferative glomerulonephritis based on kidney histology. His glomeruli were positive for the nephritis-associated plasmin receptor, plasmin activity and galactose-deficient IgA1 (Gd-IgA1). A skin biopsy immunofluorescence study revealed IgA deposition within perivascular regions but no Gd-IgA1 deposition. The final diagnosis was IgA-dominant infection-related glomerulonephritis (IRGN). The patient's renal function returned to normal after receiving immunosuppressive therapy that consisted of a glucocorticoid and a cyclophosphamide. Immunosuppressive therapy should be considered in cases of IRGN if the patient's infection is completely under control.

Abstract
Domain-based local pair natural orbital (DLPNO) coupled cluster single and double (CCSD) with triple perturbation (T) correction methods were performed to elucidate the relative stabilities of ten different intermediate structures of the CaMn4Ox cluster in the S0 state of the oxygen evolving complex (OEC) of photosystem II (PSII). Full geometry optimizations of all the S0 intermediates were performed by the UB3LYP-D3/Def2-TZVP methods, providing the assumed geometrical structures and starting natural orbitals (UNO) for DLPNO-CCSD(T)/Def2TZVP calculations. The effective exchange integrals (J) for the spin Hamiltonian models for the ten intermediates were obtained by the UB3LYP/Def2-TZVP calculations followed by the general spin projections. DLPNO-CCSD(T) calculations followed by the CBS extrapolation procedure elucidated that the (II, III, IV, IV) and (III, III, III, IV) valence states in the CaMn4O5 cluster of the OEC of the PS II were nearly degenerated in energy in the S0 state, indicating an important role of dynamical electron correlation effects for the valence and spin fluctuations in strongly correlated electron systems (SCESs) consisting of 3d transition metals.

Abstract
A new instrument dedicated to the kinetic study of low-temperature gas phase neutral-neutral reactions, including clustering processes, is presented. It combines a supersonic flow reactor with vacuum ultra-violet synchrotron photoionization time-of-flight mass spectrometry. A photoion-photoelectron coincidence detection scheme has been adopted to optimize the particle counting efficiency. The characteristics of the instrument are detailed along with its capabilities illustrated through a few results obtained at low temperatures (<100 K) including a photoionization spectrum of n-butane, the detection of formic acid dimer formation, and the observation of diacetylene molecules formed by the reaction between the C2H radical and C2H2.

Abstract
Biliary tract cancer (BTC) is typically lethal due to the difficulty of early stage diagnosis. Thus, novel biomarkers of BTC precursors are necessary. Biliary intraepithelial neoplasia (BilIN) is a major precursor of BTC and is classified as low or high grade based on cell atypia. In normal gastric mucosa, gastric gland mucin‐specific O‐glycans are unique in having α1,4‐linked N‐acetylglucosamine (αGlcNAc) attached to MUC6. Previously, we reported that αGlcNAc functions as a tumor suppressor of differentiated‐type gastric adenocarcinoma and that decreased αGlcNAc glycosylation on MUC6 in gastric, pancreatic, and uterine cervical neoplasms occurs in cancer as well as in their precursor lesions. However, αGlcNAc and MUC6 expression patterns in biliary tract neoplasms have remained unclear. Here, we analyzed MUC5AC, MUC6, and αGlcNAc expression status in 51 BTC cases and compared the expression of each with progression from low‐grade BilIN to invasive adenocarcinoma (IAC). The frequency of αGlcNAc‐positive and MUC6‐positive lesions decreased with tumor progression. When we compared each marker’s expression level with tumor progression, we found that the MUC6 expression score in IAC was significantly lower than in low‐grade or high‐grade BilIN (P < 0.001 or P < 0.01, respectively). However, the αGlcNAc expression score was low irrespective of histological grade, and also lower than that of MUC6 across all histological grades (P < 0.001 for low‐grade and high‐grade BilIN, and P < 0.01 for IAC). These results suggest that decreased expression of αGlcNAc relative to MUC6 marks the initiation of BTC progression.

Abstract
While donor-specific human leukocyte antigen (HLA) antibodies are a frequent cause for chronic antibody-mediated rejection in organ transplantation, this is not the case for antibodies targeting blood group antigens, as ABO-incompatible (ABO-I) organ transplantation has been associated with a favorable graft outcome. Here, we explored the role of CD4 T cell-mediated alloresponses against endothelial HLA-D-related (DR) in the presence of anti-HLA class I or anti-A/B antibodies. CD4 T cells, notably CD45RA-memory CD4 T cells, undergo extensive proliferation in response to endothelial HLA-DR. The CD4 T cell proliferative response was enhanced in the presence of anti-HLA class I, but attenuated in the presence of anti-A/B antibodies. Microarray analysis and molecular profiling demonstrated that the expression of CD274 programmed cell death ligand 1 (PD-L1) increased in response to anti-A/B ligation-mediated extracellular signal-regulated kinase (ERK) inactivation in endothelial cells that were detected even in the presence of interferon-γ stimulation. Anti-PD-1 antibody enhanced CD4 T cell proliferation, and blocked the suppressive effect of the anti-A/B antibodies. Educated CD25+ CD127- regulatory T cells (edu.Tregs ) were more effective at preventing CD4 T cell alloresponses to endothelial cells compared with naive Treg ; anti-A/B antibodies were not involved in the Treg -mediated events. Finally, amplified expression of transcript encoding PD-L1 was observed in biopsy samples from ABO-I renal transplants when compared with those from ABO-identical/compatible transplants. Taken together, our findings identified a possible factor that might prevent graft rejection and thus contribute to a favorable outcome in ABO-I renal transplantation.

Abstract
Disseminated carcinomatosis of the bone marrow (DCBM) in colorectal cancer is an extremely rare complication with a poor prognosis. Here, we report a case of DCBM due to rectal cancer successfully treated with a combination of FOLFOX and an anti-epidermal growth factor receptor (EGFR) agent. The patient was a 38-year-old man diagnosed with rectal cancer with multiple bone and para-aortic lymph node metastases complicated by disseminated intravascular coagulation (DIC). He first recovered from DIC following cotreatment with FOLOX plus cetuximab; subsequently, the second attack was successfully treated with FOLFOX plus panitumumab. His initial condition was extremely poor, but he survived with two FOLFOX plus anti-EGFR regimens and died 333 days after introduction of chemotherapy.

Abstract
Gastric adenocarcinoma cells secrete sulfomucins, but their role in gastric tumorigenesis remains unclear. To address that question, we generated A4gnt/Chst4 double-knockout (DKO) mice by crossing A4gnt knockout (KO) mice, which spontaneously develop gastric adenocarcinoma, with Chst4 KO mice, which are deficient in the sulfotransferase GlcNAc6ST-2. A4gnt/Chst4 DKO mice lack gastric sulfomucins but developed gastric adenocarcinoma. Unexpectedly, severe gastric erosion occurred in A4gnt/Chst4 DKO mice at as early as 3 weeks of age, and with aging these lesions were accompanied by gastritis cystica profunda (GCP). Cxcl1, Cxcl5, Ccl2, and Cxcr2 transcripts in gastric mucosa of 5-week-old A4gnt/Chst4 DKO mice exhibiting both hyperplasia and severe erosion were significantly upregulated relative to age-matched A4gnt KO mice, which showed hyperplasia alone. However, upregulation of these genes disappeared in 50-week-old A4gnt/Chst4 DKO mice exhibiting high-grade dysplasia/adenocarcinoma and GCP. Moreover, Cxcl1 and Cxcr2 were downregulated in A4gnt/Chst4 DKO mice relative to age-matched A4gnt KO mice exhibiting adenocarcinoma alone. These combined results indicate that the presence of sulfomucins prevents severe gastric erosion followed by GCP in A4gnt KO mice by transiently regulating a set of inflammation-related genes, Cxcl1, Cxcl5, Ccl2, and Cxcr2 at 5 weeks of age, although sulfomucins were not directly associated with gastric cancer development.

Abstract
Dexmedetomidine is a potent a2 adrenergic agonist, with sedative and analgesic properties which may make it a suitable sedative agent for procedures on paediatric patients. A six-year-old boy required sedation for stereotactic radiosurgical ablation of an arteriovenous malformation on two occasions. Sedation with dexmedetomidine was planned, with increased dosage used on the second occasion. On both occasions dexmedetomidine was inadequate as a sole agent and required supplementation with other agents.

Abstract
Japan is located in a seismic zone and is hence affected by earthquakes, which necessitates frequent disaster rescue activities. It is difficult for humans to access the site of an earthquake with collapsed buildings for carrying out rescue operations. The use of various mobile robots to undertake such rescue activities in place of humans has been proposed and studied to cope with such situations. Disaster sites covered with debris contain narrow spaces and irregular terrains, where robots that can change its size and rigidity should be able to move more effectively. In this study, we propose a robot system, separated into multiple robot units and variable in size and rigidity by connecting and separating them, so that it can adapt itself to a diversity of environments. To realize the proposed robot system in both mechanical and control aspects, we prototyped a group of robot units that can move as well as get connected and separated. We evaluated its thrust and ability to traverse irregular terrains as well as the automatic connection of robot units using cameras and markers.
