Antibody responses after BNT162b2 vaccination in Japanese geriatric intermediate care facilities.

Background: To evaluate antibody responses against the primary series of vaccination of severe acute respiratory syndrome coronavirus-2 [SARS-CoV-2] vaccines in the staff and residents of Japanese geriatric intermediate care facilities.

Methods: All subjects (159 staff and 96 residents) received two doses of the BNT162b2 mRNA vaccine 3 weeks apart. Baseline data of subject were collected using a structured form.

Generation of Highly Vibrationally Excited CO in Sequential Photodissociation of Iron Carbonyl Complexes.

Ultraviolet photochemistry of iron pentacarbonyl, Fe(CO), was investigated with resonantly enhanced multiphoton ionization (REMPI) spectroscopy and ion imaging. The REMPI spectrum of CO photofragments, generated by ultraviolet irradiation of Fe(CO), showed the generation in the highly vibrationally excited states with = 11-15. Analysis of the band intensities observed in the 213-235 nm region indicated that the high- CO generation was maximized at around 220 nm.

Studying and Utilizing Traditional Technologies: Microstructure and Formation Mechanism of ε-FeO on Traditional Japanese Bizen Stoneware.

Traditional Japanese Bizen stoneware is produced by firing a specific type of green clay in a wood-fired kiln at approximately 1200 °C. During this process, single crystalline branched dendrite-like particles of Al-substituted ε-FeO (ε-FeAlO) with widths and lengths of approximately 15 and 30 μm, respectively, are formed on the surface of the ceramic. Composite particles consisting of ε-FeO epitaxially connected to spinel structure compounds [comprising the Fe-substituted spinel (Mg,Fe)(Al,Fe)O and γ-FeO)] with lengths of approximately 3 μm are also generated.

Primary and Secondary Loss of CO and NO Ligands in the Ultraviolet Photodissociation of the Heteroleptic Co(CO)NO Complex.

The photodissociation dynamics of the heteroleptic Co(CO)NO complex were investigated in the metal-to-carbonyl (CO) ligand charge-transfer band to compare the reactivity of the CO and nitrosyl (NO) ligands. The final state distributions of both the CO and NO fragments were measured using resonance-enhanced multiphoton ionization (REMPI) spectroscopy and velocity-map ion-imaging. The primary CO photofragment was differentiated from the secondary fragments of the subsequent unimolecular decomposition of coordinatively unsaturated intermediates by comparing the momentum distributions.

A Cross-sectional Survey of the Clinical Manifestations and Underlying Illness of Cough.

Aim: The aim of this study was to identify factors affecting the final diagnosis of cough.

Materials And Methods: This study recruited 463 consecutive patients who visited five Japanese general hospitals due to cough from October 2006 to September 2007. Of these, 418 patients (90%) who completed a questionnaire designed to acquire data regarding clinical manifestations of cough were included.

A large abdominal wall mass as an initial manifestation of malignant mesothelioma.

Malignant mesothelioma is relatively rare and usually presents with pleural thickening and effusion at onset. In this report, we describe a 67-year-old male patient whose initial manifestation of mesothelioma was a large mass in the left flank. Mesothelioma was diagnosed from needle biopsy specimens, and, after radiotherapy, the tumor did not recur in this area.

Cough sensitivity in pure cough variant asthma elicited using continuous capsaicin inhalation.

Background: Cough variant asthma has recently been described, mainly as airway inflammation in relation to bronchial asthma, but the relationship between the two types of asthma remains unclear. Further studies of cough receptor sensitivity are necessary to fully characterize cough variant asthma.

Methods: We assessed the relevance of testing cough sensitivity using an Astograph with continuous capsaicin inhalation, and compared the results with those obtained using intermittent inhalation.

Modulated drug release from the stem-and-loop structured oligodeoxynucleotide upon UV-A irradiation in the presence of target DNA.

o-Nitrobenzyl photochemistry as induced by UV-A irradiation was applied to a photoactivated drug releasing system based on a molecular beacon strategy. A stem-and-loop structured oligodeoxynucleotide (ODN) possessing a photoreactive o-nitrobenzyl chromophore at the 3'-end and 1-aminonaphthalene quencher at the 5'-end underwent conformational change into a conventional double strand structure by hybridization with a specified target DNA. The intrinsic stem-and-loop structure suppressed photoactivated release of benzoic acid as a phantom drug from the o-nitrobenzyl chromophore because of intramolecular quenching by the 1-aminonaphthalene unit in close proximity to the chromophore.

Characteristics of patients with chronic cough who developed classic asthma during the course of cough variant asthma: a longitudinal study.

Background: Some patients develop asthmatic symptoms such as wheezing and dyspnea during the course of cough variant asthma (CVA), which are considered precursors of classical asthma.

Objectives: To identify the characteristics of such patients, we investigated the nature of CVA patients with or without developing bronchial asthma in the longitudinal study.

Methods: In 28 CVA patients whom we could observe over 5 years, duration of coughing, physical examination findings, pulmonary function and bronchial hyperresponsiveness to inhaled methacholine were retrospectively assessed.

Headache associated with postpartum cerebral angiopathy: monitoring with transcranial color-coded sonography.

We report a case of postpartum cerebral angiopathy with headache; a rare entity that affects women within the early postpartum period. Cerebral angiography revealed multiple segmental narrowings of major cerebral arteries. The patient was monitored with transcranial color-coded sonography of the middle cerebral artery.
