Site-Selective Synthesis and Concurrent Immobilization of Imine-Based Covalent Organic Frameworks on Electrodes Using an Electrogenerated Acid.

Imine-based covalent organic frameworks (COFs) are crystalline porous materials with prospective uses in various devices. However, general bulk synthetic methods usually produce COFs as powders that are insoluble in most of the common organic solvents, arising challenges for the subsequent molding and fixing of these materials on substrates. Here, we report a novel synthetic methodology that utilizes an electrogenerated acid (EGA), which is produced at an electrode surface by electrochemical oxidation of a suitable precursor, acting as an effective Brønsted acid catalyst for imine bond formation from the corresponding amine and aldehyde monomers.

Simple and scalable electrosynthesis of 1-1-hydroxy-quinazolin-4-ones.

Cathodic synthesis provides sustainable access to 1-hydroxy- and 1-oxy-quinazolin-4-ones from easily accessible nitro starting materials. Mild reaction conditions, inexpensive and reusable carbon-based electrode materials, an undivided electrochemical setup, and constant current conditions characterise this method. Sulphuric acid is used as a simple supporting electrolyte as well as a catalyst for cyclisation.

Quantitative behavioral evaluation of a non-human primate stroke model using a new monitoring system.

Background: Recently, the common marmoset () has attracted significant interest as a non-human primate stroke model. Functional impairment in non-human primate stroke models should be evaluated quantitatively and successively after stroke, but conventional observational assessments of behavior cannot fully fit this purpose. In this paper, we report a behavioral analysis using MarmoDetector, a three-dimensional motion analysis, in an ischemic stroke model using photosensitive dye, along with an observational behavioral assessment and imaging examination.

Pillar[6]quinone: facile synthesis, crystal structures and electrochemical properties.

A novel electron-deficient macrocycle, pillar[6]quinone (P[Q]6), has been synthesized for the first time by both chemical and electrochemical oxidation of pillar[6]arene, showing clear hexagonal columnar stacking in the solid state. Cathodic voltammetric studies of P[Q]6 revealed that three electrons are injected first, followed by stepwise one-electron reductions.

Surgical Anatomy for the Endoscopic Endonasal Approach to the Ventrolateral Skull Base.

The authors describe the surgical anatomy for the endoscopic endonasal approach (EEA) to the ventrolateral skull base. The ventrolateral skull base can be divided into two segments: the upper lateral and lower lateral skull base. The upper lateral skull base includes the cavernous sinus and the orbit, while the lower lateral skull base includes the petrous apex, Meckel's cave, parapharyngeal space, infratemporal fossa, etc.

Effect of a postoperative outpatient pulmonary rehabilitation program on physical activity in patients who underwent pulmonary resection for lung cancer.

Aim: Physical activity (PA) has been associated with an improvement in survival for individuals with cancer. However, little is known about the effect of postoperative pulmonary rehabilitation on PA after lobectomy in patients with lung cancer. The present study investigated the effect of outpatient rehabilitation on PA in patients with cancer after lung resection.

Treatment of pituitary carcinomas and atypical pituitary adenomas: a review.

Atypical pituitary adenomas (APAs) are aggressive tumors, harboring a Ki-67 (MIB-1) staining index of 3% or more, and positive immunohistochemical staining for p53 protein, according to the World Health Organization (WHO) classification in 2004. Pituitary carcinomas (PC) usually develop from progressive APAs and predominantly consist of hormone-generating tumors, defined by the presence of disseminations in the cerebrospinal system or systemic metastases. Most of the cases with these malignant pituitary adenomas underwent surgeries, irradiations and adjuvant medical treatments, nevertheless, the therapies are mainly palliative.

Subarachnoid hemorrhage secondary to a ruptured middle cerebral aneurysm in a patient with osteogenesis imperfecta: a case report.

Background: Osteogenesis imperfecta (OI) is a heterogeneous group of inherited disorders that occur owing to the abnormalities in type 1 collagen, and is characterized by increased bone fragility and other extraskeletal manifestations. We report the case of a patient who was diagnosed with OI following subarachnoid hemorrhage (SAH) secondary to a ruptured saccular intracranial aneurysm (IA).

Case Presentation: A 37-year-old woman was referred to our hospital because of sudden headache and vomiting.

Enhanced and suppressed infrared transmission through germanium subwavelength arrays.

We have studied the zero-order transmission of periodic germanium (Ge) subwavelength arrays in an infrared range by using finite-difference time-domain simulations. A special wavelength-selective peak in a triangular hole array of Ge film is observed with an enhanced transmission accompanied by a drastic suppression nearby, which cannot be found in a one-dimensional Ge subwavelength array and is different from the extraordinary transmission related to surface plasmons in a metal film. The electromagnetic field is found to be concentrated on both surfaces of the Ge film at this peak.

Near-field effect in the infrared range through periodic Germanium subwavelength arrays.

Using finite-difference-time-domain simulation, we have studied the near-field effect of Germanium (Ge) subwavelength arrays designed in-plane with a normal incidence. Spectra of vertical electric field component normal to the surface show pronounced resonance peaks in an infrared range, which can be applied in a quantum well infrared photodetector. Unlike the near-field optics in metallic systems that are commonly related to surface plasmons, the intense vertical field along the surface of the Ge film can be interpreted as a combination of diffraction and waveguide theory.

Clinicopathological and molecular histochemical review of skull base metastasis from differentiated thyroid carcinoma.

Skull base metastasis from differentiated thyroid carcinoma including follicular thyroid carcinoma (FTC) and papillary thyroid carcinoma (PTC) is a rare clinical entity. Eighteen FTC cases and 10 PTC cases showing skull base metastasis have been reported. The most common symptom of skull base metastasis from FTC and PTC is cranial nerve dysfunction.

Molecular status of pituitary carcinoma and atypical adenoma that contributes the effectiveness of temozolomide.

There have been several reports of temozolomide (TMZ) treatment of pituitary carcinomas and atypical adenomas. O(6)-methyl-guanine-DNA methyltransferase is not the sole molecule determining the sensitivity to TMZ in pituitary carcinomas and atypical adenomas. The Japan Society of Hypothalamic and Pituitary Tumors study suggests that MSH6, one of mismatch repair pathway enzyme, fulfills a contributory role to the efficacy of TMZ treatment for pituitary carcinomas and atypical adenomas.

DNA mismatch repair protein (MSH6) correlated with the responses of atypical pituitary adenomas and pituitary carcinomas to temozolomide: the national cooperative study by the Japan Society for Hypothalamic and Pituitary Tumors.

Context: Temozolomide (TMZ) is an alkylating agent and was a first-line chemotherapeutic agent for malignant gliomas. Recently, TMZ has been documented to be effective against atypical pituitary adenomas (APAs) and pituitary carcinomas (PCs).

Objective: The clinical and pathological characteristics of APAs and PCs treated with TMZ in Japan were surveyed and analyzed retrospectively.

Urinary growth hormone level and insulin-like growth factor-1 standard deviation score (IGF-SDS) can discriminate adult patients with severe growth hormone deficiency.

Adult growth hormone (GH) deficiency (AGHD) in Japan is diagnosed based on peak GH concentrations during GH provocative tests such as GHRP-2 stimulation test. In this study, we aimed to evaluate the ability of serum insulin-like growth factor-1 (sIGF-1) and urinary GH (uGH) at the time of awakening to diagnose AGHD. Fifty-nine patients with pituitary disease (32 men and 27 women; age 20-85 y (57.

Noncollinear parametric fluorescence by chirped quasi-phase matching for monocycle temporal entanglement.

Quantum entanglement of two photons created by spontaneous parametric downconversion (SPDC) can be used to probe quantum optical phenomena during a single cycle of light. Harris [Opt. Express 98, 063602 (2007)] suggested using ultrabroad parametric fluorescenc generated from a quasi-phase-matched (QPM) device whose poling period is chirped.

Endoscopic extracapsular removal of pituitary adenoma: the importance of pretreatment of an adjacent unruptured internal carotid artery aneurysm.

The presence of an intracranial aneurysm together with a pituitary adenoma presents tremendous risk of subarachnoid hemorrhage, during transsphenoidal surgery, particularly when the aneurysm lies near the operative field. A left supraclinoid internal carotid artery aneurysm and a clinically nonfunctioning pituitary adenoma coexisted in a 57-year-old woman. Initially, the aneurysm was treated by endovascular coil placement, and then the patient underwent pseudocapsule-based extracapsular resection of the pituitary tumor via a transnasal transsphenoidal endoscopic approach.

A narrow band-rejection filter based on block copolymers.

We demonstrate filtering characteristics of a polymer band-rejection filter (PBRF) with highly-ordered microphase-separated structure of block copolymers (BCPs). This PBRF is characterized by an Optical Density > 5 blocking at the center wavelength and narrow blocking full bandwidth of 8 nm. Moreover, the wavelength is easily tuned by blending two BCPs with different molecular-weight.

Erythropoietin-responsive sites in normal and malignant human lung tissues.

Preliminary findings of various types of globin expressed in the respiratory bronchiolar and alveolar epithelium prompted us to compare the expression of erythropoietin (Epo) and its receptor (EpoR) in normal (healthy) human lung tissues with that in malignant lung tissues. The expression of Epo and EpoR was examined at the transcriptional and protein levels in normal and malignant lung tissues by reverse transcription-PCR, western blot, and immunohistochemical analyses. EpoR mRNA, but not Epo mRNA, was detected in all samples.

Efficacy of carotid artery stenting.

Carotid Artery Stenting(CAS) was performed for 51 lesions in 46 patients for almost clinically symptomatic stenotic (> 70%)lesions of cervical carotid arteries. The lesions involved the contralateral occlusion cases in eight cases, the bilateral stenotic cases in six cases and the ipsilateral internal carotid artery stenotic cases in two cases. In all cases, endovascular technique was performed from a transfemoral approach under local anesthesia primarily.

[Comparison of ramosetron and azasetron for prevention of acute and delayed cisplatin-induced emesis in lung cancer patients].

We performed a retrospective study that compared the efficacy and safety of ramosetron with azasetron in a case of acute and delayed emesis induced by cisplatin (CDDP)-included chemotherapy in patients with lung cancer. The study subjects were 100 lung cancer patients treated with combination therapy of cisplatin, ifosfamide, irinotecan (CIC therapy). The ramosetron group and azasetron group received, respectively, ramosetron 0.

[Comparison of dexamethasone 8 mg and 16 mg for the prevention of acute and delayed cisplatin-induced emesis in patients with lung cancer].

We performed a retrospective study that compared the efficacy and safety of dexamethasone (DEX) 8 mg with DEX 16 mg in cases of acute and delayed emesis induced by cisplatin (CDDP) chemotherapy in patients with lung cancer. Sixty-eight lung cancer patients treated with combination cisplatin, ifosfamide, and irinotecan therapy were studied. The DEX 8 mg group and the DEX 16 mg group received DEX intravenous injection 30 min prior to CDDP.

[Establishment of pharmaceutical management for patient care during lung cancer chemotherapy and its quantitative evaluation].

Pharmacists should play an important role in controlling the pharmaceutical management of the patients. Although the quantitative evaluations of pharmaceutical management are required systematically, no guideline is presented for patient care during lung cancer chemotherapy. We established a complete pharmaceutical management system and evaluated the performance of the system.
