In recent decades, as the utilization of complementary and alternative medicine in the United State have been growing rapidly, regulatory controls surrounding complementary and alternative medicine(CAM) aims to ensure patient protection against unproven practices and to provide safe and effective treatments. Regulation and policy method on licensing CAM practitioners varies across the states. Over 85% of the states have the licensing system for acupuncturists, chiropractors, and naturopaths. For acupuncture, although the requirements for formal education are various across the states, a unified written examination has been adopted by almost entire states which have acupuncturist licensing law. Medicare, the public medical insurance, does not cover CAM practices except chiropractic and biofeedback. In some states, however, Medicaid programs cover some CAM therapies including acupuncture, naturopathy, and massage therapy. 67% of Health Maintenance Organizations, the private health plans, provide at least one modality of CAM services. In conclusion, government policies have been strengthened to ensure patient protection, and will continue to integrate CAM practices that are proven to be safe and effective into mainstream health care system.

Eukaryotic cells continuously integrate intrinsic and extrinsic signals to adapt to the environment. When exposed to stressful conditions, cells activate compartment-specific adaptive responses. If these are insufficient, apoptosis ensues as an organismal defense line. The mechanisms that sense stress and set the transition from adaptive to maladaptive responses, activating apoptotic programs, are the subject of intense studies, also for their potential impact in cancer and degenerative disorders. In the former case, one would aim at lowering the threshold, in the latter instead to increase it. Protein synthesis, consuming energy for anabolic processes as well as for byproducts disposal, can be a significant source of stress, particularly when difficult-to-fold proteins are produced. Recent work from our and other laboratories on the differentiation of antibody secreting cells, revealed a regulatory circuit that integrates protein synthesis, secretion and degradation (proteostasis), into cell lifespan determination. The apoptotic elimination - after an industrious, yet short lifetime - of terminal immune effectors is crucial to maintain immune homeostasis. Linking proteostasis to cell death, this paradigm might prove useful for biotechnological purposes, and the design of novel anti-cancer therapies.

Controlling the production of diverse cell/tissue types is essential for the development of multicellular organisms such as animals and plants. The Arabidopsis thaliana root, which contains distinct cells/tissues along longitudinal and radial axes, has served as an elegant model to investigate how genetic programs and environmental signals interact to produce different cell/tissue types. In the root, a series of asymmetric cell divisions (ACDs) give rise to three ground tissue layers at maturity (endodermis, middle cortex, and cortex). Because the middle cortex is formed by a periclinal (parallel to the axis) ACD of the endodermis around 7 to 14 days post-germination, middle cortex formation is used as a parameter to assess maturation of the root ground tissue. Molecular, genetic, and physiological studies have revealed that the control of the timing and extent of middle cortex formation during root maturation relies on the interaction of plant hormones and transcription factors. In particular, abscisic acid and gibberellin act synergistically to regulate the timing and extent of middle cortex formation, unlike their typical antagonism. The SHORT-ROOT, SCARECROW, SCARECROW-LIKE 3, and DELLA transcription factors, all of which belong to the plant-specific GRAS family, play key roles in the regulation of middle cortex formation. Recently, two additional transcription factors, SEUSS and GA- AND ABA-RESPONSIVE ZINC FINGER, have also been characterized during ground tissue maturation. In this review, we provide a detailed account of the regulatory networks that control the timing and extent of middle cortex formation during post-embryonic root development.

Since medical education programs in Korea and Japan seem to mutually influence each other, this review article provides a history of Japanese medical education, focusing on the way in which it influenced and was influenced by Korean medical education. In the late 19th century, the University of Tokyo established the core medical school, disseminating its scholarship and system to other medical schools. In the early 20th century, the balance between the quality and quantity of medical education became a new issue; in response, Japan developed different levels of medical school, ranging from imperial universities to medical colleges and medical vocational schools. After World War II, all of Japan's medical schools became part of the university system, which was heavily regulated by the Ministry of Education (MOE) Standard for the Establishment of Universities. In 1991, MOE deregulated the Standard; since 2000, several new systems have been established to regulate medical schools. These new approaches have included the Model Core Curriculum, 2-year mandatory postgraduate training, and a medical education accreditation system. Currently, most medical schools are nervous, as a result of tighter regulatory systems that include an accreditation system for undergraduate education and a specialty training system for postgraduate education.

Fire protection is one of important issues to ensure safety and reduce risks of nuclear power plants (NPPs). While robust programs to shut down commercial reactors in any fires have been successfully maintained, the concept and associated regulatory requirements are constantly changing or strengthening by lessons learned from operating experiences and information all over the world. As part of this context, it is necessary not only to establish specific fire hazard assessment methods reflecting the characteristics of research reactors and educational reactors but also to make decisions based on advancement encompassing numerical analyses and experiments. The objectives of this study are to address fire simulation in the control room of an educational reactor and to discuss integrity of digital console in charge of main operation as well as analysis results through comparison. Three electrical fire scenarios were postulated and twenty-four thermal analyses were carried out taking into account two turbulence models, two cable materials and two ventilation conditions. Twelve supplementary thermal analyses and six subsequent structural analyses were also conducted for further examination on the temperature and heat flux of cable and von Mises stress of digital console, respectively. As consequences, effects of each parameter were quantified in detail and future applicability was briefly discussed. On the whole, higher profiles were obtained when Deardorff turbulence model was employed or polyvinyl chloride material and larger ventilation condition were considered. All the maximum values considered in this study met the allowable criteria so that safety action seems available by sustained integrity of the cable linked to digital console within operators' reaction time of 300 s.

As the Jordanian government is in the process of implementing accrual-based IPSAS, this study aims to provide academics' perspectives on the effective implementation of accrual-based IPSAS in Jordan to authorities and regulators. The findings of a survey of 124 accounting professors at Jordanian institutions reveal that adopting accrual-based IPSAS will aid in presenting the realistic financial status of governmental bodies, with various advantages to adopting accrual-based IPSAS (e.g., enhance assets and liabilities management, decision-making process, transparency, expenditures management). On the other side, we discovered that change is met with reluctance because the majority of public-sector accountants are untrained and unqualified to apply the accrual-based IPSAS. Another main challenge is the cost of implementing the accrual-based IPSAS in the Jordanian public sector is very high. To address these issues, employees should be motivated by providing suitable training programs, reward systems, and top management support and commitment to a successful transition. Finally, we suggested that Jordanian governments commit to using IPSAS in the public sector to increase residents' socioeconomic advantages. Public sectors should implement IPSASs for improved management, transparency in financial reporting, accountability, and regulatory and supervisory agencies.

International Commission on Radiological Protection (ICRP) is an independent international organization that advances the science of radiological protection for the public benefit, particularly by providing recommendations and guidance on all aspects of protection against ionizing radiation. The ICRP is a community of more than 380 globally-recognized experts in radiological protection science, policy, and practice from more than 50 countries. As of January 2024, the ICRP is comprised of a Main Commission, the Scientific Secretariat, four Standing Committees, and 30 Task Groups under the four committees. The ICRP has released well over one hundred publications on all aspects of radiological protection. Most address a particular area within radiological protection, but a handful of the publications, the so-called fundamental recommendations, describe the overall system of radiological protection. The system for radiological protection is based on the current understanding of the science of radiation exposure and its effects along with value judgements. The ICRP offers recommendations to regulatory and advisory agencies and provides advice to management and professional staff with responsibilities for radiological protection. Legislation in most countries adheres closely to ICRP recommendations. The International Atomic Energy Agency's (IAEA) International Basic Safety Standards are based heavily on ICRP recommendations. ICRP recommendations form the core of radiological protection standards, legislation, programs, and practice worldwide.

The aim of this study was to determine the prevalence of enterococci in cheese samples and to characterize their antimicrobial resistance profiles as well as the associated resistance genes. A total of 139 enterococci were isolated from 99 cheese samples, the isolates were identified as E. faecalis (61.2%), E. faecium (15.1%), E. gallinarum (12.9%), E. durans (5.0%), E. casseliflavis (2.9%) and E. avium (2.9%). The most frequent antimicrobial resistance observed in enterococci isolates was to lincomycin (88.5%), followed by kanamycin (84.2%), gentamycin (low level, 51.1%), rifampin (46.8%) and tetracycline (33.8%). Among the isolates, the frequencies of high level gentamycin and streptomycin resistant enterococci strains were 2.2% and 5.8%, respectively. Apart from the mentioned antibiotics, low levels of resistance to ciprofloxacin, erythromycin and chloramphenicol were found. Moreover no resistance was observed against penicillin and ampicillin. The antimicrobial resistance genes including tetM, tetL, ermB, cat, aph(3’)-IIIa, ant(6)-Ia and aac(6’)-Ieaph(2”)-Ia were found in enterococci from Turkish cheese samples. In the current study, we provided data for antibiotic resistance and the occurrence of resistance genes among enterococci. Regulatory and quality control programs for milk and other dairy products from farms to retail outlets has to be established and strengthened to monitor trends in antimicrobial resistance among emerging food borne pathogens in Turkey.
