Abstract

We performed an angle-resolved photoemission spectroscopy study of Si-doped $\beta$-Ga$_2$O$_3$. We observed very small photoemission intensity near the Fermi level corresponding to non-dispersive states assigned to Si impurities. We show evidence for a quantization of these states that is accompanied by a confinement in the momentum space consistent with a real-space finite confinement observed in a previous scanning tunneling microscopy study. Our results suggest that this semi-localization in the conjugate spaces plays a crucial role in the electronic conduction of this material., Comment: 4 pages, 4 figures.

Abstract

Rietveld profiles, Moessbauer spectra and x-ray absorption fine structure (XAFS) were analyzed through the structural phase transition at Ts = 355 K in HoBaCo4O7. Excess of the oxygen content over O7 was avoided via annealing the samples in argon flow at 600 degree C. Space groups (S.G.) Pbn21c and P63mc were used to refine the structure parameters in the low- and high-temperature phases, respectively. Additionally, the Cmc21 symmetry was considered as a concurrent model of structure of the low-temperature phase. In the high-temperature phase, severe anisotropy of thermal motion of the major part of the oxygen atoms was observed. This anisotropic motion turns to be quenched as the sample is cooled below Ts. The variation of quadrupole splitting near Ts is not similar to a steplike anomaly frequently seen at the charge-ordering transition. We observe instead a dip-like anomaly of the average quadrupole splitting near Ts. Narrow distribution of the electric field gradient (EFG) over different cobalt sites is observed and explained on the basis of point-charge model. XAFS spectra show no evidence of significant difference between YBaCo4O7 (T > Ts) and HoBaCo4O7 (T < Ts). The origin of the transition at Ts is ascribed to the condensation of the libration phonon mode associated with the rigid-body rotational movements of the starlike tetrahedral units, the building blocks of kagome network. It is shown that the condensation of the libration mode is not compatible with translation symmetry for the hexagonal S.G., but compatible for the orthorhombic S.G. The orthorhombic lattice parameters and EFG components (Vxx, Vyy, Vzz) vary smoothly with temperature at approaching Ts and closely follow each other., Comment: 13 figures

Abstract

Yasushi Matsuzawa,1 Kiyoshi Hibi,1 Kenichiro Saka,1 Masaaki Konishi,1 Eiichi Akiyama,1 Naoki Nakayama,1 Toshiaki Ebina,1 Masami Kosuge,1 Noriaki Iwahashi,1 Nobuhiko Maejima,1 Kouichi Tamura,2 Kazuo Kimura1 1Division of Cardiology, Yokohama City University Medical Center, Yokohama, Japan; 2Department of Medical Science and Cardiorenal Medicine, Graduate School of Medicine, Yokohama City University, Yokohama, Japan Background: Thinning of the fibrous cap of atherosclerotic plaque is a major component of plaque vulnerability. The high resolution of optical coherence tomography (OCT) provides an accurate measurement of fibrous-cap thickness. Endothelial dysfunction is associated with inflammation and enhanced local expression of matrix metalloproteinases. We investigated the association between endothelial dysfunction and OCT-derived thin-cap fibroatheroma (TCFA) in patients with acute coronary syndromes (ACS). Methods: Seventy-four patients with ACS, who underwent both OCT examinations of the culprit lesion before percutaneous coronary intervention and peripheral endothelial function assessment as assessed by logarithmic value of reactive hyperemia index (Ln_RHI), were enrolled. Age-, sex-, hypertension-, and diabetes-matched non-coronary artery disease (non-CAD) patients were also enrolled (n=15). Results: Ln_RHI levels were significantly lower in ACS patients compared with non-CAD patients (0.56±0.26 vs 0.74±0.22, P=0.01). Furthermore, the Ln_RHIs of ACS patients with TCFA (n=44) were significantly lower than those of ACS patients without TCFA (n=30) (0.50±0.24 vs 0.65±0.26, P=0.01). There was a weak but significant positive correlation between Ln_RHI and fibrous-cap thickness (Spearman’s ρ=0.25, P=0.03). Multivariate logistic regression analysis identified lower Ln_RHI as an independent factor associated with TCFA in ACS patients (OR per 0.1 increase in Ln_RHI: 0.78 [95% CI: 0.62–0.98], P=0.03). Conclusion: Advanced endothelial dysfunction significantly correlates with a thin fibrous cap of coronary plaques in patients with ACS.

Abstract

With growing populations and pressing environmental problems, future economies will be increasingly plant-based. Now is the time to reimagine plant science as a critical component of fundamental science, agriculture, environmental stewardship, energy, technology and healthcare. This effort requires a conceptual and technological framework to identify and map all cell types, and to comprehensively annotate the localization and organization of molecules at cellular and tissue levels. This framework, called the Plant Cell Atlas (PCA), will be critical for understanding and engineering plant development, physiology and environmental responses. A workshop was convened to discuss the purpose and utility of such an initiative, resulting in a roadmap that acknowledges the current knowledge gaps and technical challenges, and underscores how the PCA initiative can help to overcome them.

Abstract

Plant dispersal mechanisms rely on anatomical and morphological adaptations for the use of physical or biological dispersal vectors. Recently, studies of interactions between the dispersal unit and physical environment have uncovered fluid dynamic mechanisms of seed flight, protective measures against fire, and release mechanisms of explosive dispersers. Although environmental conditions generally dictate dispersal distances, plants are not purely passive players in these processes. Evidence suggests that some plants may enact informed dispersal, where dispersal-related traits are modified according to the environment. This can occur via developmental regulation, but also on shorter timescales via structural remodelling in relation to water availability and temperature. Linking interactions between dispersal mechanisms and environmental conditions will be essential to fully understand population dynamics and distributions.

Abstract

BACKGROUND AND PURPOSE: Neuropsychologic deficits are well-known sequelae of traumatic brain injury. However, the cerebral correlates of these deficits are still unclear. The aim of the present study was to elucidate the regions of cerebral dysfunction correlated with such neuropsychologic deficits after traumatic brain injury. METHODS: Sets of fluorine-18 fluorodeoxyglucose–positron-emission tomography (FDG-PET) images in the resting state were obtained from 12 patients with neuropsychologic deficits after diffuse axonal injury and from 32 healthy volunteers. The cortical metabolic activity of each subject’s PET image sets was extracted using 3D stereotactic surface projection (3D-SSP). A “normal” data base was created using the extracted datasets of the healthy subjects. The patients’ datasets were compared with the normal data base by calculating a statistical Z-score on a pixel-by-pixel basis in searches for focal metabolic abnormalities. RESULTS: Group comparisons revealed hypometabolism in the cingulate gyrus with additional involvement of the lingual gyrus and cuneus. Individual case-by-case analyses disclosed differences in the site and extent of the hypometabolism in the cingulate gyrus of each case. Predominant hypometabolism was found in the anterior cingulate gyrus of 6 patients, the middle cingulate gyrus of 2 patients, and the posterior cingulate gyrus of 4 patients. CONCLUSION: Interpretation of FDG-PET using 3D-SSP facilitates the identification of regional hypometabolism in the cerebral cortex of patients after diffuse axonal injury. Dysfunction of the cingulate gyrus, lingual gyrus, and cuneus may play a crucial role in neuropsychologic deficits after traumatic brain injury.

33. Carotid Endarterectomy for Internal Carotid Artery Stenosis Associated with Persistent Primitive Hypoglossal Artery : Efficacy of Intraoperative Multi-modality Monitoring

Abstract

Persistent primitive hypoglossal artery (PPHA) is a rare vascular anomaly and is usually asymptomatic. However, the PPHA may cause multi-territorial infarction when complicated by the internal carotid artery (ICA) stenosis. In this report, we describe a 73-year-old male who simultaneously developed cerebral infarction in both carotid and vertebrobasilar territories due to ICA stenosis associated with ipsilateral PPHA. The PPHA mainly provided blood flow to the vertebrobasilar territory in this case, because the bilateral vertebral arteries were markedly hypoplastic. He underwent carotid endarterectomy under internal shunting. Intraoperative multi-modality monitoring including angiography, motor evoked potential, and near infrared spectroscopy was very useful to avoid ischemic complications during surgery. Postoperative course was uneventful. It should be reminded that persistent carotid-basilar anastomosis can cause multi-territorial cerebral infarction mimicking cardiogenic embolism and may be a candidate for aggressive prophylactic intervention, when occlusive lesions develop in the carotid artery. It is very important to monitor hemodynamic and/or electrophysiological status in both carotid and verebrobasilar territories to perform carotid endarterectomy safely in such cases.

Abstract

The plant hormone auxin mediates developmental patterning by a mechanism that is based on active transport. In the shoot apical meristem, auxin gradients are thought to be set up through a feedback loop between auxin and the activity and polar localization of its transporter, the PIN1 protein. Two distinct molecular mechanisms for the subcellular polarization of PIN1 have been proposed. For leaf positioning (phyllotaxis), an "up-the-gradient" PIN1 polarization mechanism has been proposed, whereas the formation of vascular strands is thought to proceed by "with-the-flux" PIN1 polarization. These patterning mechanisms intersect during the initiation of the midvein, which raises the question of how two different PIN1 polarization mechanisms may work together. Our detailed analysis of PIN1 polarization during midvein initiation suggests that both mechanisms for PIN1 polarization operate simultaneously. Computer simulations of the resulting dual polarization model are able to reproduce the dynamics of observed PIN1 localization. In addition, the appearance of high auxin concentration in our simulations throughout the initiation of the midvein is consistent with experimental observation and offers an explanation for a long-standing criticism of the canalization hypothesis; namely, how both high flux and high concentration can occur simultaneously in emerging veins.
