Supersymmetric boundary conditions in three-dimensional N=2 theories

We study supersymmetric boundary conditions in three-dimensional N=2 Landau-Ginzburg models and Abelian gauge theories. In the Landau-Ginzburg model the boundary conditions that preserve (1,1) supersymmetry (A-type) and (2,0) supersymmetry (B-type) on the boundary are classified in terms of subspaces of the target space (“brane”). An A-type brane is a Lagrangian submanifold on which the imaginary part of the superpotential is constant, while a B-type brane is a holomorphic submanifold on which the superpotential is constant. We also consider the N=2 Maxwell theory with boundary and the Abelian duality. Finally we make some comments on N=2 SQED with boundary condition and the mirror symmetry

米の成熟期及び発芽期中のアミラーゼの消長(農芸化学)

カンボジヤで採取されたインド型稲の浮稲(CO. 64)と非浮稲(Poik Reour)及び日本型稲の農林22号を用いて, それら生育中の茎葉部及び種子, 並びに発芽期中の種子に含まれるアミラーゼの消長を調べた。その結果, いずれの場合にも, 未発芽種子中に検出されなかったα・アミラーゼは成熟期初期の種子に出現して最高値を示したのち消失し, 発芽期に再び急増することが判った。また, β-アミラーゼについては, その成熟期及び発芽期の消長から, 発芽期中にも新たに合成される可能性の大きいことが示唆された。更に, 実験に用いた上記3品種の中では, 浮稲の種子と茎葉部に最も高いアミラーゼ含量が検出された。この高い酵素活性と浮稲の品種特性についても考察した。 / Using a floating rice (CO. 64) and a non-floating rice (Poik Reour) of Indica type collected in Cambodia and a Japonica type rice (Norin No. 22), changes of amylase contents in the shoots and the grains during maturing, dormant and germinating periods were investigated. One of the results obtained was that α-amylase of the grains, which was not detected at dormant period, appeared at earlier stage of maturing and disappeared soon later. Another was that there was a strong possibility of de novo synthesis of β-amylase during germination. Compared with other rice plants, the floating rice was found to contain higher levels of both α-and β-amylase in the grains and the shoots

Craniotomy for cerebellar hemangioblastoma excision in a patient with von Hippel–Lindau disease complicated by uncontrolled hypertension due to pheochromocytoma

INTRODUCTION: This report describes a patient with Von Hippel–Lindau (VHL) syndrome and uncontrolled hypertension due to pheochromocytoma who underwent craniotomy for the excision of a cerebellar hemangioblastoma combined with a laparoscopic adrenalectomy. CASE REPORT: A 31-year-old man presented with severe headache. MRI showed areas of abnormal enhancement in the left cerebellum that were determined to be hemangioblastoma with mass effect and obstructive hydrocephalus. His blood pressure rose abruptly and could not be controlled. CT of the abdomen revealed bilateral suprarenal tumors, and the patient was diagnosed as having VHL syndrome.On the third day, he presented with increasing headache, a decreased level of consciousness, and hemiparesis. We were not able to perform an craniotomy because abdominal compression in the prone or sitting position resulted in severe hypertension. We performed ventricular drainage to control his ICP. On the fifth day, we first performed a bilateral laparoscopic adrenalectomy to control ICP and then moved the patient to the prone position before performing a craniotomy to remove the left cerebellar hemangioblastoma. DISCUSSION & CONCLUSION: In patients with pheochromocytoma, the effects of catecholamine oversecretion can cause significant perioperative morbidity and mortality, but these can be prevented by appropriate preoperative medical management. When carrying out an excision of cerebellar hemangioblastomas in patients with intracranial hypertension complicated by abnormal hypertension due to pheochromocytoma whose blood pressure is not sufficiently controlled, tumor resection of the pheochromocytoma prior to cerebellar hemangioblastoma excision in the same surgery may prevent increased ICP and reduce perioperative risk

Dynamic structure of pharaonis phoborhodopsin (sensory rhodopsin II) and complex with a cognate truncated transducer as revealed by site-directed 13C solid-state NMR

AbstractWe have recorded 13C nuclear magnetic resonance (NMR) spectra of [3-13C]Ala, [1-13C]Val-labeled pharaonis phoborhodopsin (ppR or sensory rhodopsin II) incorporated into egg PC (phosphatidylcholine) bilayer, by means of site-directed high-resolution solid-state NMR techniques. Seven 13C NMR signals from transmembrane α-helices were resolved for [3-13C]Ala-ppR at almost the same positions as those of bacteriorhodopsin (bR), except for the suppressed peaks in the loop regions in spite of the presence of at least three Ala residues. In contrast, 13C NMR signals from the loops were visible from [1-13C]Val-ppR but their peak positions of the transmembrane α-helices are not always the same between ppR and bR. The motional frequency of the loop regions in ppR was estimated as 105 Hz in view of the suppressed peaks from [3-13C]Ala-ppR due to interference with proton decoupling frequency. We found that conformation and dynamics of ppR were appreciably altered by complex formation with a cognate truncated transducer pHtr II (1–159). In particular, the C-terminal α-helix protruding from the membrane surface is involved in the complex formation and subsequent fluctuation frequency is reduced by one order of magnitude

Protocol for making an animal model of “blindsight” in macaque monkeys

Patients with damage to the primary visual cortex (V1) can respond correctly to visual stimuli in their lesion-affected visual field above the chance level, an ability named blindsight. Here, we present a protocol for making an animal model of blindsight in macaque monkeys. We describe the steps to perform pre-lesion training of monkeys on a visual task, followed by lesion surgery, post-lesion training, and evaluation of blindsight. This animal model can be used to investigate the source of visual awareness. For complete details on the use and execution of this protocol, please refer to Yoshida et al. (2008)1 and Takakuwa et al. (2021)
