It is important to share information about other countries' pharmacists to optimize cross-border medical cooperation. This paper examines the dispensing systems and the work done by pharmacists in the United Kingdom, Germany, France, Thailand, and Malaysia so as to compare these countries' medical practices and develop a cohesive vision for the future of Japanese pharmacists. All five of the countries have dispensing assistants. Pharmacists in Japan have duties of inventory control, drug dispensing, and providing medication advice. In contrast, assistants working in other countries are responsible for some aspects of dispensing and inventory control, allowing the pharmacists to spend their time and competency in instructing patients on how to take their medication. Because of this, pharmacists were actively involved with health promotion intervention in the United Kingdom, Germany, and France. It is hoped that work done by Japanese pharmacists would transition from primarily dispensing drugs to patient care, advice, and counseling to enrich overall health promotion and health/nutrition counseling.
In recent years, several developed countries reported on new multidisciplinary roles of pharmacists and pharmacy assistants, especially considering the former's expanding functions. This paper examines differences in pharmacists' and pharmacy assistants' professional roles and the dispensing system in Japan with those in the United Kingdom, Malaysia, and the Philippines. A review of relevant literature was supplemented by interviews of dispensary staff at hospitals and community pharmacies in Malaysia and the Philippines. The UK, Philippines, and Malaysia had dispensing assistants who performed dispensing roles, while Japan did not. Although pharmacy assistants occasionally performed screening and dispensing inspections due to the lack of pharmacists, it is necessary for pharmacists participating in risk management to ensure formula optimization and monitoring. Pharmacists' contribution to medical care involves ensuring safety in drug therapy and overall medical services. Screening is the most fundamental and important function performed exclusively by pharmacists, thereby establishing their status within the medical system.
We report on the observation of quantum transport and interference in a graphene device that is attached with a pair of split gates to form an electrostatically-defined quantum point contact (QPC). In the low magnetic field regime, the resistance exhibited Fabry-Pérot (FP) resonances due to np'n(pn'p) cavities formed by the top gate. In the quantum Hall (QH) regime with a high magnetic field, the edge states governed the phenomena, presenting a unique condition where the edge channels of electrons and holes along a p-n junction acted as a solid-state analogue of a monochromatic light beam. We observed a crossover from the FP to QH regimes in ballistic graphene QPC under a magnetic field with varying temperatures. In particular, the collapse of the QH effect was elucidated as the magnetic field was decreased. Our high-mobility graphene device enabled observation of such quantum coherence effects up to several tens of kelvins. The presented device could serve as one of the key elements in future electronic quantum optic devices.
To assess dermal absorption of nicotine from tobacco leaves in relation to Green Tobacco Sickness (GTS), urinary cotinine concentrations were measured in 80 male tobacco-growing farmers and in 40 healthy males (controls) who did not handle wet tobacco leaves in Kelantan, Malaysia. Among non-smokers, urinary cotinine levels in farmers were significantly higher than those of controls; farmers with urinary cotinine of 50 ng/ml/m2 or above showed eye symptoms more frequently than those below this level (p<0.05). Farmers who did not wear protective equipment had subjective symptoms more frequently than those who used the equipment (p<0.05); some of these symptoms were seen more frequently in organophosphate (Tamaron) users than in non-users. As tobacco farmers evidence a risk of nicotine poisoning from tobacco leaves, assessment including GTS together with effects of pesticides will be necessary.
We report on magnetotransport in a high-quality graphene device, which is based on monolayer graphene (Gr) encapsulated by hexagonal boron nitride (hBN) layers, i.e., hBN/Gr/hBN stacks. In the vicinity of the Dirac point, a negative magnetoconductance is observed for high temperatures > ~ 40 K, whereas it becomes positive for low temperatures ≤ ~ 40 K, which implies an interplay of quantum interferences in Dirac materials. The elastic scattering mechanism in hBN/Gr/hBN stacks contrasts with that of conventional graphene on SiO2, and our ultra-clean graphene device shows nonzero magnetoconductance for high temperatures of up to 300 K.
Endoscopic diagnosis of gastrointestinal tumors consists of the following processes: (i) detection; (ii) differential diagnosis; and (iii) quantitative diagnosis (size and depth) of a lesion. Although detection is the first step to make a diagnosis of the tumor, the lesion can be overlooked if an endoscopist has no knowledge of what an early-stage 'superficial lesion' looks like. In recent years, image-enhanced endoscopy has become common, but white-light endoscopy (WLI) is still the first step for detection and characterization of lesions in general clinical practice. Settings and practice of routine esophagogastroduodenoscopy (EGD) such as use of antispasmodics, number of endoscopic images taken, and observational procedure are customarily decided in each facility in each country and are not well standardized. Therefore, in the present article, we attempted to outline currently available evidence and actual Japanese practice on gastric cancer screening using WLI, and provide tips for detecting EGC during routine EGD which could become the basis of future research.
The mortality rate of gastric cancer (GC) is close to the incidence rate worldwide. However, in Korea and Japan, the mortality rate of GC is less than half of the incidence rate. We hypothesized that good-quality routine esophagogastroduodenoscopy (EGD) contributes to a high detection rate for early GC (EGC) and improves mortality in these countries.
