Abstract
We report probability distributions of the number of secondary ions (SIs) emitted by sub-MeV C60 ion impacts on an organic polymer target and the characterization of their emission processes through the analysis of the distributions. The probability distributions were obtained by analyzing experimental SI counting data obtained by a time-of-flight SI mass spectrometer combined with pulsed primary ion beams, using an analytical model developed to derive the distributions from the experimental data. A series of probability distribution functions was investigated for ion impacts of C60 with sub-MeV energies (0.12-0.54 MeV), which can provide sufficient SIs per impact to determine the functions. Their complicated and undefined SI emission processes were characterized based on the determined functions.

Abstract
Sarcoidosis is a chronic granulomatous disease that can affect multiple organs. The lungs, eyes, and skin are known to be highly affected organs in sarcoidosis. There have been reports based on random muscle biopsy that 32-80% of systemic sarcoidosis comprises noncaseating granulomas; however, muscle involvement in sarcoidosis is generally asymptomatic and has an unknown frequency. We describe a case of acute to subacute sarcoid myositis of the skeletal and extraocular muscles. Typical ophthalmic involvement (manifested by infiltration of the ocular adnexa, intraocular inflammation, or infiltration of the retrobulbar visual pathways) and extraocular sarcoid myositis (as with the present case) is infrequently reported. It is important to keep in mind the rare yet perhaps underestimated entity of sarcoid myositis, and to utilize muscle biopsy and imaging tests for appropriate diagnosis and management of patients with sarcoidosis.

Abstract
Guillain-Barré syndrome (GBS) is the commonest cause of flaccid paralysis worldwide. Miller Fisher syndrome (MFS) is a variant of GBS characterized by ophthalmoplegia and ataxia. Together GBS and MFS form a continuum of discrete and overlapping subtypes, the frequency of which remains unknown. We retrospectively analysed the clinical features (antecedent symptoms, pattern of neurological weakness or ataxia, presence of hypersomnolence) of 103 patients at a single hospital in Japan. Patients were then classified according to new diagnostic criteria (Wakerley et al., 2014). Laboratory data (neurophysiology and anti-ganglioside antibody profiles) were also analysed. According to the new diagnostic criteria, the 103 patients could be classified as follows: classic GBS 73 (71%), pharyngeal-cervical-brachial weakness 2 (2%), acute pharyngeal weakness 0 (0%), paraparetic GBS 1 (1%), bifacial weakness with paraesthesias 1 (1%), polyneuritis cranialis 0 (0%), classic MFS 18 (17%), acute ophthalmoparesis 1 (1%), acute ptosis 0 (0%), acute mydriasis 0 (0%), acute ataxic neuropathy 1 (1%), Bickerstaff brainstem encephalitis 3 (3%), acute ataxic hypersomnolence 0 (0%), GBS and MFS overlap 1 (1%), GBS and Bickerstaff brainstem encephalitis overlap 1 (1%), MFS and pharyngeal-cervical-brachial weakness overlap 1 (1%). Application of the new clinical diagnostic criteria allowed accurate retrospective diagnosis and classification of GBS and MFS subtypes.

Abstract
WHAT IS KNOWN AND OBJECTIVE Midazolam (MDZ) is commonly used for sedating critically ill patients. The daily dose required for adequate sedation increases in increments over 100 h after administration. The objectives of this study were to characterize the MDZ pharmacokinetics in critically ill patients and to describe the phenomenon of increasing daily dose by means of population pharmacokinetic analysis. METHODS Data were obtained from 30 patients treated in an intensive care unit. The patients received MDZ intravenously as a combination of bolus and continuous infusion. Serum MDZ concentration was assayed by high-performance liquid chromatography. Population pharmacokinetic analysis was performed using the NONMEM software package. The alteration of clearance unexplained by demographic factors and clinical laboratory data was described as an autoinduction of MDZ clearance using a semi-mechanistic pharmacokinetic-enzyme turnover model. RESULTS AND DISCUSSION The final population pharmacokinetic model was a one-compartment model estimated by incorporating a semi-mechanistic pharmacokinetic-enzyme turnover model for clearance, taking autoinduction into account. A significant covariate for MDZ clearance was total bilirubin. An increase in total bilirubin indicated a reduction in MDZ clearance. From simulation using the population pharmacokinetic parameters obtained in this study, MDZ clearance increased 2·3 times compared with pre-induced clearance 100 h after the start of 12·5 mg/h continuous infusion. WHAT IS NEW AND CONCLUSION Autoinduction and total bilirubin were significant predictors of the clearance of MDZ in this population. Step-by-step dosage adjustment using this population pharmacokinetic model may be useful for establishing a MDZ dosage regimen in critically ill patients.

Abstract
In a conventional framework, superconductivity is lost at a critical temperature (Tc) because, at higher temperatures, gluing bosons can no longer bind two electrons into a Cooper pair. In high-Tc cuprates, it is still unknown how superconductivity vanishes at Tc. We provide evidence that the so-called ≲70-meV kink bosons that dress the quasi-particle excitations are playing a key role in the loss of superconductivity in a cuprate. We irradiated a 170-fs laser pulse on Bi2Sr2CaCu2O8+δ and monitored the responses of the superconducting gap and dressed quasi-particles by time- and angle-resolved photoemission spectroscopy. We observe an ultrafast loss of superconducting gap near the d-wave node, or light-induced Fermi arcs, which is accompanied by spectral broadenings and weight redistributions occurring within the kink binding energy. We discuss that the underlying mechanism of the spectral broadening that induce the Fermi arc is the undressing of quasi-particles from the kink bosons. The loss mechanism is beyond the conventional framework, and can accept the unconventional phenomena such as the signatures of Cooper pairs remaining at temperatures above Tc.
