Abstract
We studied 226 patients in Toyama Prefecture who were notified of COVID-19 during the first wave between March 30 and May 18, 2020. Of the 226 patients, 22 (9.7%) died, most (95%) of whom were aged ≥65 years. A large cluster comprising 59 patients (41 residents and 18 staff members) was identified in a nursing home on April 17. No deaths occurred among staff members; however, 12 of the 41 residents (29%) died. Although the threshold cycle (Ct) values were significantly lower in the 20-64 and ≥65 years age groups than in the <20 years age group, no correlation was found between the Ct values and severity, fatal outcome, or secondary infection. The haplotype network of 145 SARS-CoV-2 isolates (64%) from 226 patients was analyzed. The viral genomes of the case groups differed by less than five nucleotide bases. These data suggest that the SARS-CoV-2 strains, which were initially introduced into Toyama Prefecture in late March and early April 2020, and their closely related strains, identified as lineage B.1.1, circulated during the first wave. The reduced inter-prefectural mobility of local residents may support the lack of strain diversity in SARS-CoV-2 during the first wave of the state of emergency.

Abstract
OBJECTIVE Neurosurgeons occasionally encounter cases of subarachnoid hemorrhage (SAH) in admitted walk-in patients, termed "walk-in SAH." However, their clinical characteristics have not been fully understood. We thus, aimed to investigate several characteristics of patients with walk-in SAH and compare them with those of patients with good grade SAH who arrived at the hospital by ambulance. METHODS Between January 2011 and January 2018, consecutive patients with World Federation of Neurosurgical Society (WFNS) grade I and II aneurysmal SAH were enrolled. They were dichotomized into walk-in and ambulance groups, and their demographic and disease-related characteristics were compared. Furthermore, predictors associated with unfavorable outcomes were investigated in patients with walk-in SAH. RESULTS Of 171 patients with World Federation of Neurosurgical Society grade I and II SAH, 68 (39.8%) were categorized as walk-in SAH. The mean time for diagnosis in patients with walk-in SAH was significantly longer than that in patients who arrived by ambulance (P < 0.01). Multivariate analysis demonstrated that a lower rate of hypertension, high grades on the Barrow Neurological Institute scale, and Early Brain Edema Score were significantly associated with walk-in SAH (odds ratio [OR] 0.44, 95% confidence interval [CI] 0.21-0.91, P = 0.03; OR 0.32, 95% CI 0.13-0.76, P = 0.007; OR 0.11, 95% CI 0.02-0.51, P < 0.0001, respectively). Additionally, severe angiographic vasospasm was a significant predictor of unfavorable outcomes in walk-in SAH (OR 37.7, 95% CI 1.10-1290.90, P = 0.04). CONCLUSIONS Patients with walk-in SAH exhibit radiological characteristics associated with a more favorable outcome among patients with good grade SAH. Therefore, these patients may have a positive prognosis.

Abstract
Aphemia is now considered an impairment of speech production. We present a case of an 89-year-old right-handed woman who received intravenous thrombolysis with a recombinant tissue plasminogen activator for the ischemic symptom "loss of speech" and recovered with an ischemic lesion of the left precentral gyrus. The patient had untreated atrial fibrillation. Neurological examination showed that her level of consciousness was alert, with normal comprehension and mild lower facial droop. Head computed tomography (CT) did not reveal a hemorrhagic lesion. To treat the acute ischemic stroke, she received a recombinant tissue plasminogen activator. Just after thrombolysis, she started to speak. Then, magnetic resonance imaging (MRI) revealed an acute ischemic infarction in the dominant precentral gyrus. Follow-up MRI revealed the peripheral middle cerebral artery territory infarction in the left precentral gyrus, but she still could speak. The symptom of "loss of speech" was considered aphemia. By intravenous thrombolysis, impaired speech production in our patient was believed to be caused by an infarction in the dominant precentral gyrus. This case also demonstrated that the rare clinical symptom was due to an ischemic stroke in the territory of the distal middle cerebral artery. Clinicians who engage in stroke care need to know the rare symptoms of aphemia in the era when mechanical thrombectomy could be considered a promising treatment option for distal medium vessel occlusion.

Abstract
Seaweeds are some of the principal primary producers of marine environments, and they are important ecological elements of coastal ecosystems. The effects of harmful chemicals on seaweeds may adversely affect coastal ecosystems, hence we aimed to develop a new phytotoxicity test using the gametophytes of a common temperate kelp species, Undaria pinnatifida (KU-1630), for the widely used antifouling chemical substances Cybutryne, Diuron, Cu2+, and Zn2+. Toxicity to gametophytes of U. pinnatifida was assessed by comparing the relative growth rate (RGR) at the logarithmic growth phase. Fragmentation method, initial algal biomass, photon irradiance, and adhesive period were investigated for developing optimal test conditions. Cybutryne exposure tests were performed with seven replicates and control, the RGR ranging from 0.17 to 0.19, while mean 7-day EC50 and no observed effect concentration (NOEC) were 5.1 μg/L and 1.8 μg/L, respectively. The 7-day EC50 for other antifoulants was 14 μg/L for Diuron, 17 μg/L for Cu2+, and 1500 μg/L for Zn2+. This test method demonstrated high sensitivity and reproducibility, and it may be added to the routine methods used for toxicity evaluation of hazardous chemicals.

Abstract
OBJECTIVE Patients with World Federation of Neurosurgical Societies (WFNS) grade V subarachnoid hemorrhage (SAH) frequently have poor outcomes. The current understanding of the predictors of functional outcome only in WFNS grade V SAH is limited. METHODS Patients with WFNS grade V SAH were retrospectively analyzed between April 2008 and August 2019. Surgical treatment is commonly delayed until clinical improvement is observed using a less aggressive approach. Clinical and radiologic data on admission were assessed, and disease-related characteristics were compared between patients with favorable outcomes (modified Rankin Scale score 0-3) and those with unfavorable outcomes (modified Rankin Scale score 4-6). RESULTS A total of 144 patients were included, and 22 patients (15.3%) achieved favorable outcomes, whereas 122 patients (84.7%) had unfavorable outcomes. Surgical aneurysm repair was performed in all patients with favorable outcomes and in 21.3% of those with unfavorable outcomes. Multivariate analysis showed that Glasgow Coma Scale score of 3, high-grade Early Brain Edema Score, absence of bilaterally light reflex and neurologic improvement, and hypertension were significantly associated with unfavorable outcomes (odds ratio [OR], 9.54, P = 0.03; OR, 5.37, P = 0.04; OR, 11.80, P = 0.009; OR, 0.14, P = 0.02 and OR, 6.53, P = 0.04, respectively). CONCLUSIONS The final outcome of patients with WFNS grade V SAH was still poor and highly predicted by Glasgow Coma Scale score of 3, high-grade Early Brain Edema Score, absence of bilaterally light reflex and neurologic improvement, and a history of hypertension. The efficacy of aggressive surgical treatment for these patients remains controversial, and the indications should be clearly defined in patients with desolate clinical status on admission.

Abstract
A developing supercritical collisionless shock propagating in a homogeneously magnetized plasma of ambient gas origin having higher uniformity than the previous experiments is formed by using high-power laser experiment. The ambient plasma is not contaminated by the plasma produced in the early time after the laser shot. While the observed developing shock does not have stationary downstream structure, it possesses some characteristics of a magnetized supercritical shock, which are supported by a one-dimensional full particle-in-cell simulation taking the effect of finite time of laser-target interaction into account.

Abstract
We present an experimental method to generate quasiperpendicular supercritical magnetized collisionless shocks. In our experiment, ambient nitrogen (N) plasma is at rest and well magnetized, and it has uniform mass density. The plasma is pushed by laser-driven ablation aluminum (Al) plasma. Streaked optical pyrometry and spatially resolved laser collective Thomson scattering clarify structures of plasma density and temperatures, which are compared with one-dimensional particle-in-cell simulations. It is indicated that just after the laser irradiation, the Al plasma is magnetized by a self-generated Biermann battery field, and the plasma slaps the incident N plasma. The compressed external field in the N plasma reflects N ions, leading to counterstreaming magnetized N flows. Namely, we identify the edge of the reflected N ions. Such interacting plasmas form a magnetized collisionless shock.

Abstract
Genetic testing using reverse transcriptase real-time polymerase chain reaction (rRT-PCR) is the mainstay of diagnosis of COVID-19. However, it has not been fully investigated whether infectious viruses are contained in SARS-CoV-2 genome-positive specimens examined using the rRT-PCR test. In this study, we examined the correlation between the threshold Cycle (Ct) value obtained from the rRT-PCR test and virus isolation in cultured cells, using 533 consecutive clinical specimens of COVID-19 patients. The virus was isolated from specimens with a Ct value of less than 30 cycles, and the lower the Ct value, the more efficient the isolation rate. A cytopathic effect due to herpes simplex virus type 1 contamination was observed in one sample with a Ct value of 35 cycles. In a comparison of VeroE6/TMPRSS2 cells and VeroE6 cells used for virus isolation, VeroE6/TMPRSS2 cells isolated the virus 1.7 times more efficiently than VeroE6 cells. There was no significant difference between the two cells in the mean Ct value of the detectable sample. In conclusion, Lower Ct values in the PCR test were associated with higher virus isolation rates, and VeroE6/TMPRSS2 cells were able to isolate viruses more efficiently than VeroE6 cells.

Abstract
Intraabdominal hemorrhage is a rare complication of subarachnoid hemorrhage(SAH). Recently, there have been a number of reports about the coexistence of intracranial and Intraabdominal aneurysms caused by segmental arterial mediolysis(SAM). The etiology of SAM is still unclear, but catecholamine is known to be one of the causes of SAM. The authors report a rare case in which an increase of catecholamine by SAH affected the Intraabdominal hemorrhage during the perioperative period of SAH. A 67-year-old woman was admitted to our hospital with SAH. Cerebral angiography revealed a right internal carotid-posterior communicating artery aneurysm, and an emergent neck clipping was performed. The intraoperative finding was a saccular aneurysm with a partial red wall of the internal carotid artery. Thirteen days after SAH, the patient complained of abdominal pain, but there were no particular findings on abdominal CT. The next day, anemia progressed suddenly because of Intraabdominal hemorrhage caused by rupture of the splenic artery aneurysm. She developed shock and consciousness disturbance, and left hemiparesis due to vasospasm appeared. She recovered from shock after receiving transfusion and coil embolization of the splenic artery aneurysm. Her consciousness and left hemiparesis improved after two months of rehabilitation. The radiological findings of the splenic artery aneurysm are compatible with SAM. We believe that an increase in catecholamine by SAH affected the development and rupture of the splenic artery aneurysm. In cases of SAH with abdominal pain, a detailed examination of the abdomen might be needed, and the use of catecholamine for symptomatic vasospasm should be carefully performed.

Abstract
GOAL Intracranial arterial dissection is a major cause of ischemic stroke and subarachnoid hemorrhage in relatively young patients. We assessed the hypothesis that the tortuosity of the vertebrobasilar artery is associated with the occurrence of vertebral artery (VA) dissection, using MR angiography (MRA). MATERIALS AND METHODS This study enrolled 43 patients with VA dissection, and 63 age- and sex-matched healthy subjects were used as the controls. MRA was employed to evaluate the presence of dominant VA and the lateral shift of vertebrobasilar junction in both groups. The VA diameters were considered different when the difference was greater than .3 mm. These anatomical variations were divided into 3 types: Type 1 (vertebrobasilar junction within 2 mm from the midline), Type 2 (>2 mm-lateral shift of vertebrobasilar junction to the ipsilateral side of the dominant VA), and Type 3 (>2 mm-lateral shift of vertebrobasilar junction to the contralateral side of the dominant VA). FINDINGS The presence of dominant VA and the lateral shift of vertebrobasilar junction were more prevalent in patients with VA dissection than in the controls (OR: 3.46, P = .013, and OR: 4.51, P = .001, respectively). The lateral shift of vertebrobasilar junction was classified into Type 1 (n = 6), Type 2 (n = 13), and Type 3 (n = 17) among patients with VA dissection, while into Type 1 (n = 20), Type 2 (n = 8), and Type 3 (n = 7) among the controls. Type 3 predominance was observed in patients with VA dissection (P = .02). CONCLUSIONS Anatomical variations of the vertebrobasilar artery may play an important role in the occurrence of VA dissection.

Abstract
BACKGROUND Palliative care (PC) is increasingly recognized as essential for oncology care, and several academic societies strongly recommend integrating oncology and palliative care (IOP) in daily practice. Similarly, the Japanese government encouraged the implementation of IOP through the Cancer Control Act of 2007; however, its detailed progress remains unclear. Therefore, this cross-sectional nationwide survey was conducted to investigate the current status and hospital executive physicians' perception of IOP. METHODS The questionnaire was developed based on IOP indicators with international consensus. It was distributed to executive physicians at all government-designated cancer hospitals (DCHs, n = 399) and matched non-DCHs (n = 478) in November 2017 and the results were compared. RESULTS In total, 269 (67.4%) DCHs and 259 (54.2%) non-DCHs responded. The number of PC resources in DCHs was significantly higher than those in non-DCHs (e.g., full-time PC physicians and nurses, 52.8% vs. 14.0%, p < 0.001; availability of outpatient PC service ≥3 days per week, 47.6% vs. 20.7%, p < 0.001). Routine symptom screening was more frequently performed in DCHs than in non-DCHs (65.1% vs. 34.7%, p < 0.001). Automatic trigger for PC referral availability was limited (e.g., referral using time trigger, 14.9% vs. 15.3%, p = 0.700). Education and research opportunities were seriously limited in both types of hospitals. Most executive physicians regarded IOP as beneficial for their patients (95.9% vs. 94.7%, p = 0.163) and were willing to facilitate an early referral to PC services (54.7% vs. 60.0%, p < 0.569); however, the majority faced challenges to increase the number of full-time PC staff, and < 30% were planning to increase the staff members. CONCLUSIONS This survey highlighted a considerable number of IOP indicators met, particularly in DCHs probably due to the government policy. Further efforts are needed to address the serious research/educational gaps.

Abstract
OBJECT The rupture risk of cerebral aneurysms is determined by various factors. However, it is not clear whether the thickness of the aneurysm wall also influences the rupture risk. In this study, under the assumption that thin-walled aneurysms have a higher rupture risk compared with thick-wall aneurysms, we evaluate the usefulness of computed fluid dynamics(CFD)to identify thin-walled cerebral aneurysms. METHODS Fifty-four unruptured middle cerebral aneurysms from 53 patients were analyzed using CFD before the operation. We divided these aneurysms into two groups: translucent-type aneurysms and others. To analyze the difference of these groups, individual elements(age, gender, volume, and aspect ratio)and hemodynamic factors(wall shear stress[WSS], flow coefficient, and flow coefficient per volume)were examined using CFD. RESULTS Univariate analysis detected significant relationships between the translucent-type aneurysms and gender, aspect ratio, WSS and flow coefficient per volume. Multiple logistics regression also identified a significant relationship with gender and flow coefficient per volume. The receiver operating characteristic curve demonstrated that the flow coefficient per volume could predict translucent-type aneurysms(area under the curve 0.84, cut-off value 1.32, sensitivity 76.2%, and specificity 87.9%). CONCLUSION Gender and the flow coefficient per volume could predict translucent-type aneurysms of the middle cerebral artery. CFD analysis might be a useful tool to predict translucent-type aneurysms.

Abstract
GOAL There are an increasing idea that the inflammation contributes to vascular diseases in various organs. The pathogenesis of both cerebral small vessel disease such as cerebral microbleeds and carotid plaque may be associated with chronic inflammation. This study was aimed to evaluate the correlation between microbleeds and carotid plaque characteristics. MATERIALS AND METHODS This study enrolled 85 patients who underwent surgical/endovascular treatments for carotid artery stenosis between January 2009 and July 2016. Their clinical data were precisely analyzed. T2*-weighted magnetic resonance (MR) imaging was performed to detect the cerebral microbleeds. The carotid plaque with high signal intensity on T1-weighted MR imaging was categorized into vulnerable plaque. FINDINGS The microbleeds was detected in 17 of 85 (20%). The prevalence of vulnerable carotid plaque and previous symptomatic lacunar infarction was significantly greater in the patients with microbleeds than in those without (P = .001 and P = .03, respectively). Multiple logistic regression analysis showed that the vulnerable plaque was significantly associated with the presence of microbleeds when adjusted for age, alcohol intake, antiplatelet drug use, the presence of previous symptomatic lacunar infarction, and coronary artery disease (P = .009, OR = 5.38, 95% CI = 1.51-21.0). CONCLUSIONS These findings suggest the correlation between microbleeds and vulnerable plaque in patients with severe (>70%) carotid artery stenosis. Systemic, chronic inflammation may play a key role in both small and large arteries' disease of the brain. The knowledge may be valuable to fully understand the entity of cerebrovascular diseases as one of systemic, chronic inflammation.

Abstract
To investigate possible roles of T helper type 2 (Th2) cytokines in the anti-arthritic effects of a blood fluke, Schistosoma mansoni (Sm), for mouse collagen-induced arthritis (CIA), wild-type (WT), signal transducer and activator of transcription 6 (STAT6) knock-out (KO) and interleukin (IL)-10 KO mice were infected with Sm. Three weeks after infection, the mice were immunized with bovine type II collagen (IIC). Arthritis severity was monitored by scoring, measurement of paw thickness and the presence of ankylosis. Serum anti-IIC IgG levels, splenic cytokine production and cytokine gene expression in the popliteal lymph nodes (PLNs) were measured and compared among WT and gene-KO mice. Consistent with our previous findings, Sm infection reduced the arthritis severity in WT mice. Splenic production of IL-17A and tumor necrosis factor (TNF)-α was reduced by the infection. In contrast, Sm infection markedly exacerbated CIA in STAT6 KO mice. In the KO mice, IL-17A production was increased by the infection. Conversely, Sm infection did not affect the exacerbated arthritis in IL-10 KO mice, although IL-17A production was reduced by the helminth. Our results suggest that signaling via STAT6 (presumably IL-4 and/or IL-13) and IL-10 is required for the suppression of CIA by Sm infection, but through different mechanisms. STAT6 was essential for helminth-induced reduction of IL-17A, whereas regulation of the basal arthritis severity by IL-10 was needed in order for it to be sufficiently suppressed by the helminth.

Abstract
Although Aspergillus fumigatus is the major agent of invasive aspergillosis, an increasing number of infections are caused by its cryptic species, especially A. lentulus and the A. viridinutans species complex (AVSC). Their identification is clinically relevant because of antifungal drug resistance and refractory infections. Species boundaries in the AVSC are unresolved since most species have uniform morphology and produce interspecific hybrids in vitro. Clinical and environmental strains from six continents (n = 110) were characterized by DNA sequencing of four to six loci. Biological compatibilities were tested within and between major phylogenetic clades, and ascospore morphology was characterised. Species delimitation methods based on the multispecies coalescent model (MSC) supported recognition of ten species including one new species. Four species are confirmed opportunistic pathogens; A. udagawae followed by A. felis and A. pseudoviridinutans are known from opportunistic human infections, while A. felis followed by A. udagawae and A. wyomingensis are agents of feline sino-orbital aspergillosis. Recently described human-pathogenic species A. parafelis and A. pseudofelis are synonymized with A. felis and an epitype is designated for A. udagawae. Intraspecific mating assay showed that only a few of the heterothallic species can readily generate sexual morphs in vitro. Interspecific mating assays revealed that five different species combinations were biologically compatible. Hybrid ascospores had atypical surface ornamentation and significantly different dimensions compared to parental species. This suggests that species limits in the AVSC are maintained by both pre- and post-zygotic barriers and these species display a great potential for rapid adaptation and modulation of virulence. This study highlights that a sufficient number of strains representing genetic diversity within a species is essential for meaningful species boundaries delimitation in cryptic species complexes. MSC-based delimitation methods are robust and suitable tools for evaluation of boundaries between these species.

Abstract
Background and Purpose: We recently noted a gradual change in the boundary electroencephalography (EEG) oscillation of 7.8 Hz between theta (θ) and alpha (α) bands in response to increased atherosclerosis levels in the elderly. The aim of this study was to investigate the role of boundary EEG oscillations of θ-α bands on cognitive functions in vascular cognitive impairments (VCI) patients. Materials and Methods: We examined 55 patients with VCI in carotid stenosis, and underwent EEG in a resting state with closed eyes for 5 min. The asymmetry index (AI) along homologous channel pairs (e.g., F7-8) was assessed using neuronal activity topography (NAT). AI referring to 10 frequency components ranging from 4 to 20 Hz and neuropsychological assessments including linguistic competence were analyzed. Results: The main findings was that the language score had a positive association with AI in 7.8 Hz at F7-8 and a negative association with AI in 6.3 Hz at C3-4 and 14.1 Hz at F3-4. Conclusion: EEG asymmetry in a boundary range might have a special role in linguistic competence, suggesting the application of neural oscillation on the cognitive function evaluation and neurorehabilition induced by a frequency-specific transcranial alternating current stimulation.

Abstract
PURPOSE Sudden onset severe occipital/nuchal pain is believed to be a typical symptom of vertebral artery dissection(VAD). However, recent developments in diagnostic imaging have suggested that VAD is not always associated with such pain. This study aimed to analyze the clinical features of initial symptoms in patients with VAD. METHODS In total, this study included 29 consecutive patients who were referred to our hospital because of only headache and/or nuchal pain due to VAD between 2011 and 2016. In this study, their clinical features were precisely assessed, including the pain location, onset pattern, duration, intensity, disease period, diagnosis modality, and prognosis. Both MRI and MRA were performed for all subjects. Cerebral angiography and thin-slice T1-weighted MRI were additionally performed in selected cases. RESULTS Of the 29 patients, 23 presented with occipital headache and/or nuchal pain. The pain was persistent in 26/29 and ipsilateral in 29/29. However, only 16/29 reported a typical sudden onset. Only 12/29 complained of severe pain, while the other 17/29 presented with dull pain. The mean interval between onset and hospitalization was 7.4 days(0 to 30 days)and the mean interval between hospitalization and diagnosis was 3.9 days(0 to 21 days). Intramural hematoma was identified in 21/29 patients using thin-slice T1-weighted MRI. CONCLUSION Only 55% of patients with VAD demonstrate typical occipital/nuchal pain with sudden onset. Both MRI and MRA should be indicated for patients who complain of persistent, unilateral pain in the occipital/nuchal regions to prevent VAD being missed during diagnosis.

Abstract
OBJECT Recent studies have shown that computational fluid dynamics(CFD)analysis is useful to evaluate flow dynamics of intracranial aneurysms. However, CFD analysis still requires high costs and substantial time even now. This study aimed to evaluate whether newly developed software can shorten the time for analysis and serve useful information during clipping surgery for intracranial aneurysms. METHODS CFD analysis was performed in 55 unruptured cerebral aneurysms in 51 patients. The time required for analysis of each aneurysm was recorded. On the basis of CFD analysis, both pressure and wall shear stress(WSS)were calculated as the values at the systolic and diastolic phases, and also the mean value through one cardiac cycle. These data were compared between thin-wall points and other points within each aneurysm. RESULTS The average time required for analysis was 3 hours, ranging from 1 to 15 hours. The CFD data could be referenced during surgery in each patient. The pressure in about 93% and 80% of the thin-wall points was higher than that at other points within each aneurysm in the systolic and diastolic phases, respectively. However, there was no significant correlation between WSS and wall thickness in each aneurysm. CONCLUSION This study clearly shows that newly-developed software is simple and requires much shorter time for CFD analysis than previous methods. Higher pressure through the cardiac cycle may efficiently predict a thin-wall region within intracranial aneurysms, which strongly suggests that CFD analysis would be a valuable tool to determine the treatment strategy in patients with unruptured aneurysms.

Abstract
Background: Previously, we reported on vascular cognitive impairment (VCI) templates, consisting of patients with VCI associated with carotid stenosis (>60%) using a quantitative electroencephalographic (EEG) technique called neuronal activity topography (NAT). Here using the VCI templates, we investigated the hypothesis that internal carotid artery-intima-media thickness (ICA-IMT) is associated with EEG spectrum intensity (sNAT) and spectrum steepness (vNAT). Methods: A total of 221 community-dwelling elderly subjects were recruited. Four groups were classified according to quartiles of ICA-IMT as assessed by ultrasonography: control group A, normal (≤0.9 mm); group B, mild atherosclerosis (1-1.1 mm); group C, moderate atherosclerosis (1.2-1.8 mm); and group D, severe atherosclerosis (≥1.9 mm). EEG markers of power ratio index (PRI), and the binary likelihood of being in the VCI group vs. the that of being in control group A (sL x:VCI-A , vL x:VCI-A ) were assessed, respectively. Differences in mean total scores for PRI, sL x:VCI-A , vL x:VCI-A , between control group A and the other groups were compared using Dunnett's test, respectively. Results: The mean total scores of the PRI were 3.25, 3.00, 2.77, and 2.26 for groups A, B, C, and D, respectively. There was a significant decrease in the PRI in group D compared with group A (P = 0.0066). The mean total scores of the sL x:VCI-A were -0.14, -0.11, -0.1, and -0.03 for groups A, B, C, and D, respectively. The sL x:VCI-A in group D was significantly higher compared to that in group A (P < 0.0001). The mean total scores of the vL x:VCI-A were -0.04,-0.01, 0.01, and 0.06 for group A, B, C, and D, respectively. The vL x:VCI-A in group D and group C was significantly higher compared to that in group A, respectively (P < 0.0001, P = 0.02). Conclusion: Community-dwelling elderly subjects in the increased carotid atherosclerosis of ICA-IMT (≥1.9 mm) were at greatest risk of an EEG change as assessed by NAT.

Abstract
We evaluated retrospectively the treatment modalities and clinical outcome of 14 patients with intracranial dural arteriovenous fistula (AVF) involving cortical veins and dural sinuses except the cavernous and lateral sinuses. The location of arteriovenous shunt was the confluence of the sinuses and superior sagittal sinus (in 2 patients), superior petrosal sinus (1), marginal sinus (1), parasigmoid sinus (1), cortical vein at the anterior fossa (2), cortical vein of the parietal lobe (2), petrosal vein (2), and the cortical vein around the craniocervical junction (3). Of 12 patients who underwent endovascular and/or surgical treatment, five patients were treated only with microsurgery, six only with endovascular therapy, and one with combined surgical and endovascular procedure. Angioanatomical result was complete occlusion of the lesion in all the cases treated with surgery, and 80 to 100% occlusion in cases with endovascular treatment. Clinical outcome was GR in nine patients, MD in two, SD in one, VS in one, and D in one. The natural history of the lesion at each location and angioanatomical feature including the hemodynamic condition in each case should be precisely evaluated to select endovascular, surgical, or a combined procedure for the management of these unusual types of intracranial dural AVF.

GOAL This prospective study was aimed to prove the hypothesis that multilineage-differentiating stress-enduring (Muse) cells are mobilized from bone marrow into peripheral blood in patients with ischemic stroke. MATERIALS AND METHODS This study included 29 patients with ischemic stroke. To quantify the circulating Muse cells, peripheral blood was obtained from all patients on admission and at days 7 and 30. Using fluorescence-activated cell sorting, Muse cells were identified as stage-specific embryonic antigen-3-positive cells. The control values were obtained from 5 healthy volunteers. Separately, immunohistochemistry was performed to evaluate the distribution of Muse cells in the bone marrow of 8 autopsy cases. FINDINGS The number of Muse cells robustly increased within 24 hours after the onset, compared with the controls, but their baseline number and temporal profile widely varied among patients. No clinical data predicted the baseline number of Muse cells at the onset. Multivariate analysis revealed that smoking and alcohol intake significantly affect the increase in circulating Muse cells. The odds ratio was .0027 (P = .0336) and 1688 (P = .0220) for smoking and alcohol intake, respectively. The percentage of Muse cells in the bone marrow was .20% ± .17%. CONCLUSION This study shows that pluripotent Muse cells are mobilized from the bone marrow into peripheral blood in the acute stage of ischemic stroke. Smoking and alcohol intake significantly affect their temporal profile. Therapeutic interventions that increase endogenous Muse cells or exogenous administration of Muse cells may improve functional outcome after ischemic stroke.

Abstract
This study was aimed to analyze the outer diameter of the involved arteries in moyamoya disease, using three-dimensional (3D) constructive interference in steady state (CISS) and direct surgical inspection. Radiological evaluation was performed in 64 patients with moyamoya disease. As the controls, six patients with severe middle cerebral artery (MCA) stenosis and 17 healthy subjects were also recruited. On 3D-CISS, the outer diameter was quantified in the supraclinoid portion of internal carotid artery (C1), the horizontal portions of MCA (M1) and anterior cerebral artery (A1), and basilar artery. The involved carotid fork was directly observed during surgery in another series of three adult patients with moyamoya disease. In 53 adult patients with moyamoya disease, the outer diameters of C1, M1, and A1 segments were 2.3 ± 0.7 mm, 1.3 ± 0.5 mm, and 1.0 ± 0.4 mm in the involved side (n = 91), being significantly smaller than the control (n = 17), severe M1 stenosis (n = 6), and non-involved side in moyamoya disease (n = 15, P < 0.01). There were significant correlations between Suzuki’s angiographical stage and the outer diameters of C1, M1, and A1 (P < 0.001). The laterality ratio of C1 and M1 was significantly smaller in unilateral moyamoya disease (n = 20) than the controls and severe MCA stenosis (P < 0.01). Direct observations revealed a marked decrease in the outer diameter of the carotid fork (n = 3). These findings strongly suggest specific shrinkage of the involved arteries in moyamoya disease, which may provide essential information to distinguish moyamoya disease from other intracranial arterial stenosis and shed light on the etiology and novel diagnosis cue of moyamoya disease.

Abstract
BACKGROUND The middle meningeal artery (MMA) is known to function as one of the important collateral routes in moyamoya disease. However, the anterior branch frequently courses within the lesser wing of the sphenoid bone and can easily be damaged during craniotomy for bypass surgery. This prospective study aimed to study the surgical anatomy of the MMA and to establish the technique to preserve it during bypass surgery for moyamoya disease. METHODS Twenty-two patients with moyamoya disease underwent STA-MCA anastomosis combined with indirect bypass on 27 sides. The anatomical relationship between the anterior branch of the MMA and lesser wing was classified into three types: the bridge, monorail, and tunnel types. During surgery, the lesser wing was carefully resected with a rongeur or high-speed diamond drill to preserve the anterior branch of the MMA. RESULTS The anterior branch of the MMA was classified into the bridge type in 5 sides (18.5 %), monorail type in 10 sides (37.0 %), and tunnel type in 12 sides (44.5 %). Patient age was closely related to the anatomical findings (χ (2) test, p = 0.0168). Careful resection of the lesser wing with a rongeur could preserve bridge- and monorail-type MMAs (100 and 71.4 %, respectively). However, drilling out of the lesser wing under a surgical microscope was essential to preserve the tunnel-type MMA. Intraoperative indocyanine green videoangiography was useful to confirm patency during surgery. CONCLUSIONS It is essential to understand the surgical anatomy of the MMA around the pterion in order to preserve its anterior branch during bypass surgery for moyamoya disease.

Abstract
We describe a higher magnifying power operating microscope system to improve one method of high-quality microsurgical clipping for cerebral aneurysm in some cases. This higher magnification is achieved by a new lens design in the optical system, which makes the image of the object very clear at high magnifications (distinctiveness of 7 μm). This higher-resolution operating microscope system provides the surgeon with higher-magnified images (at the maximum of more than 30× magnifications as each working distance) in the operating field. The magnifications can be changed from low power (2.9×) to high power (62.0×) depending on the circumstances in a given procedure. We have used this operating microscope system on 11 patients with microsurgical clipping for cerebral aneurysms. Microsurgical treatment could be performed safely and precisely. All aneurysms were treated without any technical complications. We think that the use of this microscope would have potential benefits for microsurgical treatment for cerebral aneurysms because of better visualization.

Abstract
AIMS In a phase III study conducted among Japanese patients with type 2 diabetes mellitus (T2DM), linagliptin 5 and 10 mg showed clinically meaningful improvements in glycaemic parameters after 12 and 26 weeks compared with placebo and voglibose, respectively. This extension study assessed long-term tolerability of linagliptin over 52 weeks. METHODS Japanese patients with T2DM who completed either phase of a 12-week/26-week study comparing linagliptin monotherapy with placebo or voglibose were eligible to enrol. In the extension study, the comparator groups switched to linagliptin 5 or 10 mg, while the linagliptin groups maintained dosage. RESULTS In all, 540 patients received at least one dose of linagliptin 5 or 10 mg and 494 completed the extension. Long-term treatment with linagliptin was well tolerated; adverse events (AEs) of special interest and serious AEs occurred in small percentages of patients. Drug-related AEs occurred in 10.2 and 10.6% of patients in the linagliptin 5- and 10-mg groups, respectively, and discontinuations due to drug-related AEs occurred in 1.1 and 0.7%, respectively. Only one (0.4%) patient in each dose group experienced investigator-defined hypoglycaemia during the treatment period (both events were non-severe). Body weight was not clinically altered in either group. The glycated haemoglobin A1c profiles over time were similar with linagliptin 5 and 10 mg. CONCLUSIONS These findings provide evidence for the safety and tolerability of oral linagliptin at either 5 or 10 mg for up to 52 weeks for the treatment of Japanese patients with T2DM, without clinically relevant increase in the risk of hypoglycaemia or weight gain.

Abstract
The purpose of the present study was to investigate the renoprotective effect of telmisartan, an angiotensin II receptor antagonist, on the early stages of diabetic nephropathy in obese Zucker rats, which is a type 2-related diabetes mellitus model. Telmisartan 1, 3 or 10 mg/kg/day was orally administered to 7-week-old rats that demonstrated glucose tolerance without albuminuria or proteinuria, for 24 consecutive weeks (Experiment A). In another experiment (Experiment B), oral administration of telmisartan 10 mg/kg/day was initiated at the age of 16 weeks after the rats demonstrated marked proteinuria, and continued for 24 weeks. Telmisartan inhibited the increase in proteinuria and albuminuria in a dose-dependent manner, and the inhibition for all telmisartan groups was statistically significant by the completion of administration (Experiment A). Telmisartan also displayed similar inhibitory effects on proteinuria and albuminuria in Experiment B. Histologically, telmisartan [3 and 10 mg/kg/day] was associated with a significant decrease in the progression of glomerulosclerosis, and significantly improved interstitial cell infiltration, interstitial fibrosis and dilation and atrophy of renal tubules. Furthermore, telmisartan treatment was associated with a tendency towards normalized plasma lipids (total cholesterol and triglyceride). Our results suggest that telmisartan has a definite renoprotective effect against renal injury in type II diabetic nephropathy.

Abstract
The effect of transient stress waves on the microstructure of HMX–Estane, a polymer-bonded explosive (PBX), is studied. Calculations carried out concern microstructures with HMX grain sizes on the order of 200 μm and grain volume fractions in the range of 0.50–0.82. The microstructural samples analysed have an aspect ratio of 5:1 (15×3 mm), allowing the transient wave propagation process resulting from normal impact to be resolved. Boundary loading is effected by the imposition of impact face velocities of 50–200 m s
−1
. Different levels of grain–binder interface strength are considered. The analysis uses a recently developed cohesive finite element framework that accounts for coupled thermal–mechanical processes involving deformation, heat generation and conduction, failure in the forms of microcracks in both bulk constituents and along grain/matrix interfaces, and frictional heating along crack faces. Results show that the overall wave speed through the microstructures depends on both the grain volume fraction and interface bonding strength between the constituents and that the distance traversed by the stress wave before the initiation of frictional dissipation is independent of the grain volume fraction but increases with impact velocity. Energy dissipated per unit volume owing to fracture is highest near the impact surface and deceases to zero at the stress wavefront. On the other hand, the peak temperature rises are noted to occur approximately 2–3 mm from the impact surface. Scaling laws are developed for the maximum dissipation rate and the highest temperature rise as functions of impact velocity, grain volume fraction and grain–binder interfacial bonding strength.

Abstract
AIMS To evaluate the efficacy and safety of linagliptin 5 and 10 mg vs. placebo and voglibose in Japanese patients with type 2 diabetes mellitus (T2DM). METHODS This study enrolled patients with inadequately controlled T2DM who were previously treated with one or two oral antidiabetics or were drug naÏve. After a 2 to 4-week washout and placebo run-in, 561 patients were randomized (2 : 2 : 2 : 1) to double-blind treatment with linagliptin 5 or 10 mg qd, voglibose 0.2 mg tid or placebo. The primary endpoint was the change from baseline in haemoglobin A1c (HbA1c) with linagliptin vs. placebo after 12 weeks and vs. voglibose after 26 weeks. RESULTS Baseline characteristics were well balanced across treatment groups (overall mean HbA1c was 8.01%). The adjusted mean (95% confidence interval) treatment differences at week 12 were -0.87% (-1.04, -0.70; p < 0.0001) and -0.88% (-1.05, -0.71; p < 0.0001) for linagliptin 5 and 10 mg vs. placebo and at week 26 were -0.32% (-0.49, -0.15; p = 0.0003) and -0.39% (-0.56, -0.21; p < 0.0001) for linagliptin 5 and 10 mg vs. voglibose. At week 12, mean HbA1c was 7.58, 7.48 and 8.34% in patients receiving linagliptin 5 mg, linagliptin 10 mg and placebo, respectively. At week 26, mean HbA1c was 7.63% with linagliptin 5 mg, 7.50% with linagliptin 10 mg and 7.91% with voglibose. Drug-related adverse event rates were comparable across treatment groups over 12 weeks (9.4% linagliptin 5 mg, 8.8% linagliptin 10 mg and 10.0% placebo) and 26 weeks (11.3% linagliptin 5 mg, 10.6% linagliptin 10 mg and 18.5% voglibose). There were no documented cases of hypoglycaemia. CONCLUSIONS Linagliptin showed superior glucose-lowering efficacy and comparable safety and tolerability to both placebo and voglibose in Japanese patients with T2DM.

Abstract
Donor artery dissection is a known cause of technical failure in microvascular anastomosis. A method for detection and direct repair of donor artery dissection before superficial temporal artery (STA) to middle cerebral artery (MCA) anastomosis is described using a high magnification operating microscope (maximum 50.4× magnification). Before STA-MCA anastomosis, the stump of the STA is stained using methylrosaniline chloride (pyoctaninum blue) and is observed under higher magnifications. Microsurgical suturing of the arterial dissection is performed before the anastomosis procedure under the high magnification microscope. This method was used in two patients with symptomatic hemodynamic cerebrovascular occlusive disease. Postoperative angiography revealed good patency and no complications occurred. This method may be useful for detection and direct repair of arterial dissection in small vessel walls before STA-MCA anastomosis.

Abstract
ABSTRACTTo assess the adhesion of nitride coatings on metals, titanium 6% aluminum 4% vanadium substrates were coated with titanium nitride (TiN) using both cathodic arc and electron beam evaporation. Titanium aluminum nitride ((Ti, Al)N) was also deposited using cathodic arc evaporation. The interfaces of the coated samples were loaded in tension using a high speed shock wave which caused spallation either at the interface, in the coating or in the metal. Scanning acoustic microscopy analysis of the spalled samples detected delaminations at the interface in the samples deposited by cathodic arc evaporation. DYNA2D modeling of plate impact spallation experiments revealed the tensile adhesion strength for TiN deposited by both techniques was ≈ 2.0 GPa. The tensile adhesion strength for (Ti, Al)N was less than 1.5 GPa.

Abstract
Background: We report a safe and precise technique of microvascular anastomosis at higher magnifications (30 – 50 ×) in neurosurgery and evaluate our experiences to examine the utility of this method for cerebral revascularization in various situations. Methods: A retrospective review was carried out of patients who underwent microvascular anastomosis using a high-magnified operating microscope. This method was performed in 30 patients with 35 microvascular anastomoses in various situations. This microscope has two optical systems, a standard zooming system and a newly developed high magnification system. High resolution and good depth of focus are achieved by a new lens design in the optical system, which makes the image of the object very clear at higher magnifications. In this operating microscope, the combination of a 10 × eyepiece and the 200, 250, and 300-mm objective lens enables a range of final magnifications from 2.9 × to 50.4 ×. Results: This method enabled one to pay attention to performing atraumatic manipulations of small vessels and correct suturing, intima-to-intima, of vessel walls. Microvascular anastomoses were performed safely and precisely at higher magnifications. All anastomoses were patent. Conclusion: It is obvious that practical final magnifications of more than 30 × in neurosurgery would be super-magnified operative views. Microvascular anastomosis at 30 – 50 × magnifications (super-microvascular anastomosis) can help neurosurgeons to improve their skills, with good visualization, and to be safe and accurate when conducting cerebral revascularization in various situations.

Abstract
BACKGROUND We report a precise technique for EC-IC bypass surgery using a stereoscopic high-resolution microscope at magnifications of 40x and 50x. METHODS A stereoscopic operating microscope (Mitaka MM50 Surgical Microscope; Mitaka Kohoki Co, Tokyo, Japan) was used in STA-MCA anastomosis. This microscope has 2 optical systems, a standard zooming system, a newly developed high-magnification system, and 4 fixed working distances of 200, 250, 300 and 350 mm, with highest magnifications of 50.4x at 200 mm and 40.3x at 250 mm. High resolution is achieved by a new lens design in the optical system, which makes the image of the object very clear at high magnification. The magnification can be changed depending on the circumstances in a given procedure. The STA-MCA anastomoses were performed using this microscope. RESULTS Very small vessels were observable, and arterial anastomosis could be performed precisely at high magnification. All anastomoses were patent on postoperative angiograms. CONCLUSIONS Use of the new microscope allows visualization and manipulation of small vessels at high magnification and high resolution and may be very useful in EC-IC bypass surgery.

Abstract
AIMS To develop predictive formulas using short-term changes in glycaemic parameters [haemoglobin A1c (HbA1c) and fasting plasma glucose (FPG)] with sitagliptin, a highly selective dipeptidyl peptidase-4 inhibitor, to assess longer term steady-state changes in HbA1c. METHODS Results from two, 12-week, double-blind studies of sitagliptin in Japanese patients with type 2 diabetes mellitus receiving once-daily sitagliptin 100 mg were used to construct linear models to develop predictive formulas based on study 1 (S1) and to validate them using study 2 (S2). HbA1c and FPG were the primary and the key secondary end-point for both studies and were both used to develop predictive formulas. RESULTS The predictive formulas using HbA1c+/-FPG results (slope of change) from week 0 to week 4 in S1 showed high correlations between fitted and observed week 12 HbA1c: for HbA1c alone R2=0.76, for HbA1c+FPG R2=0.89. When using the sitagliptin 100 mg group of S2 data set to assess the validity of the predictive formulas, high correlations for HbA1c alone (R2=0.76) and for HbA1c+FPG (R2=0.77) were also observed. Data using a lower dose (25 mg once daily) of sitagliptin also demonstrated similar results. CONCLUSIONS The early responses (over 4 weeks) in HbA1c and FPG with sitagliptin can be used to accurately predict later responses (at week 12) in HbA1c in Japanese patients with type 2 diabetes mellitus. Additional studies applying this approach to other agents with diverse mechanisms are important.
