Intracranial germ cell tumors (iGCTs) are the second most common brain tumors among children under 14 in Japan. The World Health Organization classification recognizes several subtypes of iGCTs, which are conventionally subclassified into pure germinoma or non-germinomatous GCTs. Recent exhaustive genomic studies showed that mutations of the genes involved in the MAPK and/or PI3K pathways are common in iGCTs; however, the mechanisms of how different subtypes develop, often as a mixed-GCT, are unknown. To elucidate the pathogenesis of iGCTs, we investigated 61 GCTs of various subtypes by genome-wide DNA methylation profiling...

Our present study investigated whether the ventilatory and gas exchange responses show different dynamics in response to sinusoidal change in cycle work rate or walking speed even if the metabolic demand was equivalent in both types of exercise. Locomotive parameters (stride length and step frequency), breath-by-breath ventilation (V̇E) and gas exchange (CO2 output (V̇CO2) and O2 uptake (V̇O2)) responses were measured in 10 healthy young participants. The speed of the treadmill was sinusoidally changed between 3 km·h-1 and 6 km·h-1 with various periods (from 10 to 1 min)...

Th17 cells and the cytokine they produce, interleukin (IL)-17, play an important role in tumor progression in humans and in mice. IL-6 and IL-23 are critical cytokines for the differentiation and propagation of Th17 cells, respectively. Bacterial lipopolysaccharides (LPS) are known to stimulate immune cells to produce such inflammatory cytokines. Contrary to Escherichia coli (E. coli) LPS, LPS from Spirulina has low toxicity and barely induces in vivo production of IL-6 and IL-23 in mice. We examined the antitumor effects of Spirulina LPS compared to E...

Although Japan has been considered to have little lead (Pb) pollution in modern times, the actual pollution situation is unclear. The present study aims to investigate the extent of Pb pollution and to identify the pollution sources in Japan using stable Pb isotope analysis with kidneys of wild rats. Wild brown (Rattus norvegicus, n = 43) and black (R. rattus, n = 98) rats were trapped from various sites in Japan. Mean Pb concentrations in the kidneys of rats from Okinawa (15.58 mg/kg, dry weight), Aichi (10...

To develop a safer and more potent paclitaxel (PTX) formulation, we prepared various O/W emulsions by using egg phosphatidylcholine, Tween 80, and a mixture of triglycerides with different fatty acid chain lengths as the co-surfactant, surfactant, and oil phase component, respectively. The mean particle diameters of the PTX-emulsions prepared were around 100 nm. The PTX-emulsions did not provoke histamine release from rat mast cells and did not show any significant hemolytic activity, suggesting that PTX-emulsions are biocompatible...

 Rivastigmine patches exhibit stable effects when attached once a day, and may reduce Alzheimer's disease (AD) patient's or caregiver's burden. On the other hand, it was reported that adverse events, such as dermal disorder, frequently appeared after the start of rivastigmine administration. We retrospectively investigated medical records in 120 patients with moderate or mild AD in whom rivastigmine administration was started in the Department of Neurology, Fukuoka University Hospital between July 2011 and June 2014 (43 males, 77 females, mean age: 76...

Epidermal growth factor receptor (EGFR) is a well-validated oncological target molecule for monoclonal antibody therapies and Sym004 is a novel anti-EGFR antibody mixture comprising two recombinant chimeric IgG1 antibodies against non-overlapping epitopes of EGFR. Because EGFR is highly expressed in the majority of esophageal squamous cell carcinomas (ESCCs), we investigated the efficacy of Sym004 in human ESCC cell lines. Forty eight ESCC cell lines were treated with three kinds of anti-EGFR antibodies (Sym004, cetuximab, and panitumumab)...

INTRODUCTION: CT angiography has gained widespread acceptance for preoperative evaluation of blood supply in patients with colorectal cancer. However, there have been few reports that pertain to the splenic flexure, for which surgery is technically difficult. We used preoperative CT angiography and CT colonography to evaluate blood supply to the splenic flexure. METHODS: We defined the splenic flexure as the junction of the distal third of the transverse colon and the proximal third of the descending colon...

Inhibitors of AKR1B10 belonging to the aldo-keto reductase (AKR) superfamily are considered promising candidates for anti-cancer drugs. AKR1B1, a structurally similar isoform of AKR1B10, is involved in glucose metabolism. Thus, selective inhibition of AKR1B10 is required for the development of anti-cancer drugs. In this study, we first compared correlations between melting temperature and the 50% inhibition concentration obtained from differential scanning fluorimetry (DSF) and an enzyme inhibitory experiment, respectively, and a good correlation was found, except for compounds with low solubility...

Meibomian glands are located in the eyelids and secrete meibum, which gives rise to the lipid layer of the tear film. Changes to these glands can lead to the development of meibomian gland dysfunction (MGD), which is associated with various ocular symptoms such as fatigue, dryness, burning sensation, and heavy sensation. The diagnosis of MGD thus relies on evaluation of ocular symptoms, meibum condition, and lid margin abnormalities. The recent development of noninvasive meibography and tear interferometry has provided important insight into meibomian gland structure and function, respectively...

BACKGROUND: Among all procedures, surgical site infections (SSIs) in colorectal surgery continue to have the highest rate, accounting for 5%-45%. To prevent the bacterial colonization of suture material, which disables local mechanisms of wound decontamination, triclosan-coated sutures were developed. We assessed the effectiveness of triclosan-coated sutures used for skin closure on the rate of SSIs in colorectal cancer surgery. METHODS: Until August 2012, we used conventional methods for skin closure in colorectal cancer surgery at the Department of Gastroenterological Surgery, Fukuoka University Faculty of Medicine...

Perspiration monitoring can be utilized for the detection of certain diseases, such as thermoregulation and mental disorders, particularly when the patients are unaware of such disorders or are having difficulty expressing their symptoms. Until now, several devices for perspiration monitoring have been developed; however, such devices tend to have a relatively large exterior, considerable power consumption, and/or less sensitivity. Recently, we developed a small, wireless device for perspiration monitoring...

The three-dimensional (3D) structures of the right atrial appendage (RAA) and left atrial appendage (LAA) were compared to clarify why thrombus formation less frequently occurs in RAA than in LAA. Morphological differences between RAA and LAA of 34 formalin-preserved cadaver hearts were investigated. Molds of RAA and LAA specimens were made and the neck areas, volumes of the atrial appendages (AA), and amount of pectinate muscles (PMs) were analyzed using multidetector computed tomography. In RAA, most PMs were connected to one another and formed a "dendritic" appearance and the inner surface area was smaller than in LAA...

Pancreatic cancer continues to have a bleak prognosis. Hardly any therapeutic advances have been made in the last few years and consequently most efforts have focused on preventing its development and on diagnosing precursor lesions. In this regard, the use of statins as a preventive factor and the implementation of screening programmes in high-risk patients are gaining ground. In the field of treatment, there is greater focus on the role of neoadjuvant therapy in pancreatic cancer and on a multimodal approach to the disease, with few advances in effective novel therapies...
