Diallylamine-maleic acid copolymer (DAM)-nonwoven fabric (DAM-f), a fibrous adsorbent, contains DAM with zwitter-ionic functional groups and forms a hydration layer on the surface. The aim of this report was to evaluate the adsorption selectivity of DAM-f to semi-volatile organic acid (C1-C5). In the aqueous phase, formic acid dissolved in the hydration layer bound to the imino group of DAM-f due to anion exchange interaction. In the gas phase, the adsorption amounts of organic acids increased with the exposure time...

It is difficult to understand nursing practically for students who have just started studying nursing, because they cannot imagine the actual medical scene. The authors expect that they can improve nursing learning through experiences in virtual medical environments supported by ICT (information and commnication technology). We developed teaching materials in nursing education, and in a previous study we reported that the use of a virtual hospital was useful for students who had not had medical experience. The aim of the present study was to have students consider the meaning of a hospital room ceiling...

The effects of color perception are utilized in visual displays for the purpose of safety in the workplace and in daily life. These effects, generally known as color functionality, are divided into four classifications: visibility, legibility, conspicuity and discriminability. This article focuses on the relationship between the color functionality of color schemes used in visual displays for occupational and environmental safety and color vision deficiency (particularly congenital red-green color deficiency), a critical issue in ophthalmology, and examines the effects of color functionality on the perception of the color red in individuals with protan defects...

Nuclear fusion technology is expected to create new energy in the future. However, nuclear fusion requires a large amount of tritium as a fuel, leading to concern about the exposure of radiation workers to tritium beta radiation. Furthermore, countermeasures for tritium-polluted water produced in decommissioning of the reactor at Fukushima Daiichi Nuclear Power Station may potentially cause health problems in radiation workers. Although, internal exposure to tritium at a low dose/low dose rate can be assumed, biological effect of tritium exposure is not negligible, because tritiated water (HTO) intake to the body via the mouth/inhalation/skin would lead to homogeneous distribution throughout the whole body...

The main risk factors in ischemic heart diseases, including myocardial infarction, are hypertension, dyslipidemia, diabetes, obesity and smoking. The incidence of ischemic heart disease in Japan has been lower than that in Western countries because of differences in lifestyle and the anatomy of the coronary arteries, but the situation has been changing recently because of the westernization of lifestyle. Cardiovascular diseases have become the second most common cause of death in Japan, and 40% of those deaths are attributed to ischemic heart disease...

We analyzed the effects of 100 mg/day sitagliptin and a switch to mitiglinide calcium hydrate/voglibose compound tablets (MIT/VOG) in patients with type 2 diabetes mellitus (T2DM) treated with 50 mg/day sitagliptin. Five patients with T2DM treated with 50 mg/day sitagliptin and hemoglobin A1c (HbA1c) of ≥6.5% were switched to MIT/VOG, or the dose of sitagliptin was increased to 100 mg/day. The effects of the changes in therapy were compared in a crossover fashion by continuous glucose monitoring. The primary endpoint was mean amplitude of glycemic excursions (MAGE), and the secondary end points were 24-hour mean blood glucose level and mean blood glucose level from 0:00 a...

The purpose of this study was to extract the risk factors recognized by students before pediatric nursing practice in order to conduct medical safety education based on student's learning readiness. Third-year nursing students of A nursing college used the P-mSHELL model to find the risk factors in a simulated pediatric hospital room, and the researchers analyzed the contents. The students recognized four categories of risk factors: "burden on the family", "characteristics of the infant", "characteristics of children with disease", and "the family's cognition and understanding"...

Although chronic obstructive pulmonary disease (COPD) affects one in several smokers, only a few patients are correctly diagnosed compared to the estimated number of patients. Several recent reports indicate that the development of rotator cuff tears is related to smoking. In this study, we investigated smoking status in patients with rotator cuff tears and evaluated the possibility of undiagnosed COPD by a pulmonary function test. The subjects were 150 consecutive patients over 40 years old, who had been diagnosed with rotator cuff tears and had been examined by a pulmonary function test before surgery in our orthopedic department between April 2011 and June 2015...

Myringoplasty is one of the basic procedures in otologic surgery, and is important to achieve good hearing outcome. The temporal fascia is most widely used and considered to be a stable graft in this procedure, although 10-20% of patients develop reperforation after surgery, which is often hard to repair, even by revision surgery. We herein conducted revision myringoplasty using a cartilage graft to repair postoperative reperforation in 7 patients (8 ears) with chronic otitis media. The patients were 3 males and 4 females, aged 13-80 years with an average of 53...

Meige syndrome is a relatively rare type of oral facial dystonia. The dominant symptoms involve involuntary eye blinking and chin thrusting. Some patients may experience excessive tongue protrusion, squinting, muddled speech, or uncontrollable contraction of the platysma muscle. A 44-year-old Japanese male was suffering from schizophrenia. The initial presentation of his psychosis consisted of auditory hallucinations, delusions of persecution, psychomotor excitement, loosening association, and restlessness...

Culture-independent methods to detect microorganisms have been developed in parallel with traditional culture-based methods ever since the classification of bacteria based on 16S rRNA gene sequences was advocated in the 1970s. The development and the prevalence of culture-independent molecular technologies have provided revolutionary progress in microbial studies. The development of these technologies contributes significantly to the research of microorganisms that cannot be detected by traditional methods such as culture-dependent methods...

The passive sampler is a simple device for collecting gaseous compounds. It is affected by environmental conditions such as relative humidity, but a dehumidification system (DHS) has not been developed for it. We have developed a dehumidification device for the passive sampler for determining 1,3-butadiene. It consists of a passive sampler surrounded by a DHS consisting of a basket filled with granular magnesium perchlorate as the dehumidification agent. The passive sampler consists of a porous polytetrafluoroethylene tube packed with Carboxen 1000 adsorbent...

Obstructive Sleep Apnea (OSA) is a common disease associated with major cardiovascular diseases. Male subjects are more at higher risk for OSA than female subjects. The Berlin questionnaire is a beneficial screening tool for OSA and has 14 items. The Berlin questionnaire may need some adjustment for Thai or Asian populations. We aimed to find items that should be asked in the Berlin questionnaire to identify high risk for obstructive sleep apnea among Thai male healthcare workers. This study was performed in Thai male healthcare workers over the age of 35 and currently working at the Faculty of Medicine, Khon Kaen University...

We studied the carcinogenic effects caused by repetitive irradiation at a low dose, which has received attention in recent years, and examined the experimental methods used to evaluate radiation-induced carcinogenesis. For this experiment, we selected a mouse with as few autochthonous cancers as possible. Skin cancer was selected as the target for analysis, because it is a rare cancer in mice. Beta-rays were selected as the radiation source. The advantage of using beta-rays is weaker penetration power into tissues, thus protecting organs, such as the digestive and hematogenous organs...
