이 증례보고는 심한 수면무호흡증으로 진단된 환자로, 다른 구강 내 OSA치료 장치와 nCPAP치료에 적응을 못하는 66세 남자 환자였다. 하악골에 2개의 교정용 마이크로 임프란트를 식립한 후, 식립 2주 후부터 구강외 고정원인 개조된 안면마스크에서 마이크로 임프란트에 힘을 가하여 하악골을 전진시켰다. 마이크로 임프란트를 이용한 하악골전진술(MiMA)은 심한 수면 무호흡환자의 AHI (apnea-hypopnea index), 코골이 및 심한 수면 무호흡증상을 개선할 수 있었다. This case report describes the treatment of a 66 year old adult patient with a diagnosis of severe obstructive sleep apnea who was intolerant of nasal continuous positive airway pressure (nCPAP) treatment and oral appliance therapy. An alternative treatment of snoring and obstructive sleep apnea (OSA) with 2 orthodontic microimplants anchored to the mandible providing skeletal anchorage for mandibular advancement was implemented. After a 2 week healing period, a custom designed facemask provided extraoral anchorage to which the microimplants were connected to for titratable mandibular advancement. Microimplant Mandibular Advancement (MiMA) therapy resulted in resolution of the symptoms of severe OSA with a reduction of the apnea-hypopnea index (AHI), snoring and OSA symptoms.

VARIETIES OF CAPITALISM AND GOVERNMENT SPENDING IN DEVELOPED AND DEVELOPING COUNTRIES
JOACHIM AHRENS,RAINER SCHWEICKERT,JULIANE ZENKER 중앙대학교 경제연구소 2015 Journal of Economic Development Vol.40 No.1
Empirical papers on the size of government suffer from neglecting preferences for government activity as discussed in the literature on varieties of capitalism. Cross-country evidence for a sample of 126 developed and developing countries reveals a global divide. Among developing countries, Asian countries are closer to continental European economies, i.e., they reveal relatively higher levels of spending dependent on the quality of governance. Latin American countries rather tend towards low-spending anglo-saxon economies and spend to stabilize rather than to fight inequality. Considering these preferences, we do not find evidence that open countries spend more in order to buffer macroeconomic risks.

The yeast Candida albicans is a member of the microbiota in the gastrointestinal and urogenital tracts of most healthy persons, but it can also cause symptomatic infections, especially in immunocompromised patients. During the life-long association with its human host, C. albicans generates genetically altered variants that are better adapted to changes in their environment. A prime example of this microevolution is the development of resistance to the commonly used drug fluconazole, which inhibits ergosterol biosynthesis, during antimycotic therapy. Fluconazole resistance can be caused by mutations in the drug target, by changes in the sterol biosynthesis pathway, and by gain-of-function mutations in transcription factors that result in the constitutive upregulation of ergosterol biosynthesis genes and multidrug efflux pumps. Fluconazole also induces genomic rearrangements that result in gene amplification and loss of heterozygosity for resistance mutations, which further increases drug resistance. These genome alterations may affect extended chromosomal regions and have additional phenotypic consequences. A striking case is the loss of heterozygosity for the mating type locus MTL in many fluconazole-resistant clinical isolates, which allows the cells to switch to the mating-competent opaque phenotype. This, in turn, raises the possibility that sexual recombination between different variants of an originally clonal, drug-susceptible population may contribute to the generation of highly fluconazole-resistant strains with multiple resistance mechanisms. The gain-of-function mutations in transcription factors, which result in deregulated gene expression, also cause reduced fitness. In spite of this, many clinical isolates that contain such mutations do not exhibit fitness defects, indicating that they have overcome the costs of drug resistance with further evolution by still unknown mechanisms.
