Despite the extraordinary gravimetric energy densities, Li-O2 batteries are still facing a technological challenge; limited round trip efficiency leading to insufficient cycle life. Recently, carbonaceous electrode materials were found to be one of the primary origins of the limited cycle life, as they produce irreversible side products during discharge. A few investigations based on non-carbonaceous materials have demonstrated largely suppressed accumulation of irreversible side products but such studies have focused mainly on the materials themselves rather than delicate morphology control...

A 77-year-old man visited our hospital with chief complaints of difficulty in hearing, nasal discharge and fever. The patients was diagnosed with otitis media, and his fever continued at approximately 38°C despite the administration of clarithromycin. After that, dyspnea on exertion developed and chest X-ray examination indicated multiple infiltrative shadows. PR3-ANCA levels were high (238-fold of the normal levels), and granulomatosis with polyangiitis (GPA) was diagnosed on the basis of clinical symptoms, laboratory results, and pathological findings...

Congenital cataracts can occur as a non-syndromic isolated ocular disease or as a part of genetic syndromes accompanied by a multi-systemic disease. Approximately 50% of all congenital cataract cases have a heterogeneous genetic basis. Here, we describe three generations of a family with an autosomal dominant inheritance pattern and common complex phenotypes, including bilateral congenital cataracts, short stature, macrocephaly, and minor skeletal anomalies. We did not find any chromosomal aberrations or gene copy number abnormalities using conventional genetic tests; accordingly, we conducted whole-exome sequencing (WES) to identify disease-causing genetic alterations in this family...

Although protein-bound paclitaxel (PTX, Abraxane(®)) has been established as a standard PTX-based therapy against multiple cancers, its clinical success is limited by unfavorable pharmacokinetics, suboptimal biodistribution, and acute toxicities. In the present study, we aimed to apply the principles of a layer-by-layer (LbL) technique to improve the poor colloidal stability and pharmacokinetic pattern of nanoparticle albumin-bound paclitaxel (nab-PTX). LbL-based nab-PTX was successfully fabricated by the alternate deposition of polyarginine (pARG) and poly(ethylene glycol)-block-poly (L-aspartic acid) (PEG-b-PLD) onto an albumin conjugate...

The recreational use of synthetic cathinones has dramatically increased in recent years, which is partly due to easy accessibility and ability of synthetic cathinones to exert rewarding effects similar to cocaine and methamphetamine. Many synthetic cathinones have already been scheduled in several countries; however, novel and diverse synthetic cathinones are emerging at an unprecedented rate, often outpacing regulatory processes. Recently, designer modifications of the basic cathinone molecule are usually performed on the alpha-carbon position...

Mucoepidermoid carcinoma (MEC) is the most common type of malignant neoplasm in the minor salivary gland. The hard palate is a frequently involved site of MEC. The treatment of low-grade MEC on the hard palate is wide local resection with a tumor-free margin. In the present case, the maxillary defect was reconstructed using a buccal fat pad (BFP) flap, followed by application of 4-hexylresorcinol (4HR) ointment for 2 weeks. The grafted BFP successfully covered the tumor resection defect without tension and demonstrated complete re-epithelialization without any complications...

Itaconate, a C5 unsaturated dicarboxylic acid, is an important chemical building block that is used in manufacturing high-value products, such as latex and superabsorbent polymers. Itaconate is produced by fermentation of sugars by the filamentous fungus Aspergillus terreus. However, fermentation by A. terreus involves a long fermentation period and the formation of various byproducts, resulting in high production costs. E. coli has been developed as an alternative for producing itaconate. However, fermentation of glucose gives low conversion yields and low productivity...

Inflammaging is defined as low-grade, chronic, systemic inflammation in aging, in the absence of overt infection. Age-associated deterioration of gastrointestinal function could be ascribed to the inflammaging, although evidence is yet to emerge. Here we show that microvessels in aging mouse intestine were progressively deprived of supportive structures, microvessel-associated pericytes and adherens junction protein vascular endothelial (VE)-cadherin, and became leaky. This alteration was ascribed to up-regulation of angiopoetin-2 in microvascular endothelial cells...

Nociception is one of the most complex senses that is affected not only by external stimulation but also internal conditions. Previous studies have suggested that circadian rhythm is important in modulating nociception. REV-ERBα knock-out (KO) mice have disrupted circadian rhythm and altered mood-related phenotypes. In this study, we examined the role of REV-ERBα in inflammatory nociception. We found that the nociceptive sensitivity of KO mice was partially enhanced in mechanical nociception. However, this partial alteration was independent of the circadian rhythm...

BACKGROUND AND PURPOSE: Cancer patients with cryptogenic stroke often have high plasma D-dimer levels and lesions in multiple vascular regions. Hence, if patients with cryptogenic stroke display such characteristics, occult cancer could be predicted. This study aimed to investigate the clinical characteristics of cryptogenic stroke as the first manifestation of occult cancer and to determine whether plasma D-dimer levels and lesions in multiple vascular regions can predict occult cancer in patients with cryptogenic stroke...

We have synthesized the single crystalline Y2C electride of centimetre-scale by floating-zone method and successfully characterized its anisotropic electrical and magnetic properties. In-plane resistivity upturn at low temperature together with anisotropic behavior of negative magnetoresistance is ascribed to the stronger suppression of spin fluctuation along in-plane than that along the c-axis, verifying the existence of magnetic moments preferred to the c-axis. Superior magnetic moment along the c-axis to that along in-plane direction strongly demonstrates the anisotropic magnetism of Y2C electride containing magnetically easy axis...

Chronic granulomatous disease (CGD) is a primary immunodeficiency disease caused by impaired phagocytic function. Hematopoietic stem cell transplantation (HSCT) is a definitive cure for CGD; however, the use of HSCT is limited because of associated problems, including transplantation-related mortality and engraftment failure. We report a case of a patient with CGD who underwent successful HSCT following a targeted busulfan and fludarabine reduced-toxicity myeloablative conditioning. Intravenous busulfan was administered once daily for 4 consecutive days (days -8 to -5), and the target area under the curve was 75,000 µg·hr/L...

A new species of Neobathyclupea is described from two specimens collected off Myanmar and off Socotra Island. The new species is most similar to N. malayana, but differs from it and other congeners in having jet-black coloured fins, larger pseudobranch, dorsal-pterygiophore pattern and some body proportions. Neobathyclupea malayana is re-diagnosed. Individual variations in armament of the preopercle and in the dorsal-pterygiophore patterns within Bathyclupeidae are discussed.

The inward rectifier Kir2.1 current (IKir2.1) was reported to be facilitated by fluid flow. However, the mechanism underlying this facilitation remains uncertain. We hypothesized that during K(+) influx or efflux, [K(+)] adjacent to the outer mouth of the Kir2.1 channel might decrease or increase, respectively, compared with the average [K(+)] of the bulk extracellular solution, and that fluid flow could restore the original [K(+)] and result in the apparent facilitation of IKir2.1. We recorded the IKir2.1 in RBL-2H3 cells and HEK293T cells that were ectopically over-expressed with Kir2...
