REVIEW
Nao Nishimura, Mureo Kasahara, Kenji Ishikura, Satoshi Nakagawa
Brain-dead donor organ transplantation has been available to children in Japan since the 2010 revision of the Organ Transplant Law. Of the 50-60 brain-dead donor organ transplants performed annually in Japan, however, very few (0-4 per year) are performed in children. Again, while those receiving liver, heart, and kidney transplants are reported to fare better than their counterparts in the rest of the world, organ shortage is becoming a matter of great concern. Very few organs become available from brain-dead donors or are transplanted to adults if made available at all, with some children dying while on the brain-dead organ waiting list...

BACKGROUND: Ovarian clear cell carcinoma (OCCC) is mostly resistant to standard chemotherapy that results in poor patient survival. To understand the genetic background of these tumours, we performed whole-genome sequencing of OCCC tumours. METHODS: Tumour tissue samples and matched blood samples were obtained from 55 Japanese women diagnosed with OCCC. Whole-genome sequencing was performed using the Illumina HiSeq platform according to standard protocols. RESULTS: Alterations to the switch/sucrose non-fermentable (SWI/SNF) subunit, the phosphatidylinositol-3-kinase (PI3K)/Akt signalling pathway, and the receptor tyrosine kinase (RTK)/Ras signalling pathway were found in 51%, 42%, and 29% of OCCC tumours, respectively...

Despite the high incidence of neuropathic and inflammatory pain worldwide, effective drugs with few side effects are currently unavailable for the treatment of chronic pain. Recently, researchers have proposed that inhibitors of purinergic chemical transmission, which plays a key role in the pathological pain response, may allow for targeted treatment of pathological neuropathic and inflammatory pain. However, such therapeutic analgesic agents have yet to be developed. In the present study, we demonstrated that clodronate, a first-generation bisphosphonate with comparatively fewer side effects than traditional treatments, significantly attenuates neuropathic and inflammatory pain unrelated to bone abnormalities via inhibition of vesicular nucleotide transporter (VNUT), a key molecule for the initiation of purinergic chemical transmission...

AIM: We designed a safety and dose-finding trial of tadalafil administered for fetal growth restriction (FGR). METHODS: Three cases were initially commenced on 10 mg/day and monitored for major adverse events. Should a major adverse event be observed in one or more of the three cases, an examination into its relation with tadalafil would be conducted by a safety evaluation committee. If one or more of these new cases exhibited the same adverse event, the trial would be stopped completely...

BACKGROUND: Current treatment options for lymphatic malformations (LMs) are multimodal. Recently, the effectiveness of treating LMs with Eppikajyutsuto (TJ-28) has been reported. TJ-28 is a kind of oral herbal medicine classified as the traditional Japanese Kampo medicine. CASE PRESENTATION: A 12-year-old girl was admitted to our hospital for intermittent upper abdominal pain. Radiological examinations revealed a large (9.5 × 5.8 × 10.0 cm) retroperitoneal LM, which was suspected to adhering and stretching both pancreas head and duodenum...

Herps, especially amphibians, are particularly susceptible to climate change, since temperature tightly controls many parameters of their biological cycle - above all, their phenology. The timing of herps' activity or migration period - in particular the dates of their first appearance in spring and first breeding - and the shift to earlier dates in response to warming since the last quarter of the 20(th) century has often been described up to now as a nearly monotonic trend towards earlier phenological events...

A macro/mesoporous Co-N-C-decorated separator is proposed to confine and reutilize migrating polysulfides. Endowed with desirable structure and synchronous lithio/sulfiphilic chemistry, macro/mesoporous Co-N-C interface manipulates large polysulfides adsorption uptake, high polysulfides adsorption kinetics, reversible electrocatalysis toward anchored-polysulfides redox, and facile charge transport. It significantly boosts simple MWCNT/S-70wt% cathode achieving high initial capacities (e.g. 1406 mAh g-1 at 0...

Many studies have shown that healthy elderly subjects and patients with Alzheimer's disease (AD) who carry the apolipoprotein E (ApoE) ε4 allele have worse cognitive function and more severe brain atrophy than non-carriers. However, it remains unclear whether this ApoE polymorphism leads to changes of cognition and brain morphology in healthy young adults. In this study, we used an established model to measure verbal episodic memory and core executive function (EF) components (response inhibition, working memory and task switching) in 32 ApoE ε4 carriers and 40 non-carriers between 20 years and 40 years of age...

In 2013, national serosurveillance detected a high seroprevalence of antibodies to pertussis toxin (PT) from Bordetella pertussis among Japanese adults. Thus, we aimed to determine the cause(s) of this high seroprevalence, and analyzed the titers of antibodies to PT and filamentous hemagglutinin (FHA) among adults (35-44 years old), young children (4-7 years old), and older children (10-14 years old). Our quantitative analyses revealed that adults had higher seroprevalences of anti-PT IgG and PT-neutralizing antibodies, and similar titers of anti-FHA IgG, compared to the young and older children...

Methods: In individuals aged 40-75 years consecutively submitted to routine health assessment at one single center, four criteria of eligibility for statin were defined: BR-1, BR-2 (LDL-c above or at least 30 mg/dL above the goal recommended by the Brazilian Guideline, respectively), USA-1 and USA-2 (10-year risk estimated by the PCE ≥ 5...

Vibrationally resolved photoelectron spectra of CuOH(-) and CuSH(-) have been determined via velocity map imaging method to investigate the transitions of X(1)A'←X(2)A' at 532nm. Adiabatic detachment energies of CuOH(-) and CuSH(-) are assigned to 0.995(12) and 1.098(12) eV, respectively. Combined theoretical calculations with Franck-Condon simulations, it allows extracting the vibrational frequencies in neutral, which yields 629(32) cm(-1) with CuO stretching mode and 387(24) cm(-1) with CuS stretching mode for CuXH (X=O and S)...
