<P>CHDH (choline dehydrogenase) is an enzyme catalyzing the dehydrogenation of choline to betaine aldehyde in mitochondria. Apart from this well-known activity, we report here a pivotal role of CHDH in mitophagy. Knockdown of CHDH expression impairs CCCP-induced mitophagy and PARK2/parkin-mediated clearance of mitochondria in mammalian cells, including HeLa cells and SN4741 dopaminergic neuronal cells. Conversely, overexpression of CHDH accelerates PARK2-mediated mitophagy. CHDH is found on both the outer and inner membranes of mitochondria in resting cells. Interestingly, upon induction of mitophagy, CHDH accumulates on the outer membrane in a mitochondrial potential-dependent manner. We found that CHDH is not a substrate of PARK2 but interacts with SQSTM1 independently of PARK2 to recruit SQSTM1 into depolarized mitochondria. The FB1 domain of CHDH is exposed to the cytosol and is required for the interaction with SQSTM1, and overexpression of the FB1 domain only in cytosol reduces CCCP-induced mitochondrial degradation via competitive interaction with SQSTM1. In addition, CHDH, but not the CHDH FB1 deletion mutant, forms a ternary protein complex with SQSTM1 and MAP1LC3 (LC3), leading to loading of LC3 onto the damaged mitochondria via SQSTM1. Further, CHDH is crucial to the mitophagy induced by MPP+ in SN4741 cells. Overall, our results suggest that CHDH is required for PARK2-mediated mitophagy for the recruitment of SQSTM1 and LC3 onto the mitochondria for cargo recognition.</P>

Background: Micafungin, a potent inhibitor of 1,3-β-D-glucan synthase, is a novel antifungal agent of the echinocandin class. In vitro study showed that micafungin was effective against Aspergillus species as well as Candida species, but clinical data on the prophylactic efficacy against invasive fungal infections (IFIs) other than candidiasis are still lacking. Materials and Methods: We identified 60 consecutive adult hematopoietic stem cell transplantation (HSCT) recipients who received at least 3 doses of micafungin during neutropenic period. Micafungin was started as an alternative in patients who were intolerant or had adverse events (AEs) to primary prophylactic antifungal agents. We retrospectively reviewed the medical records and analyzed the efficacy and safety of micafungin for prophylaxis against IFIs. Results: The patients either had autologous (n=9) or allogeneic (n=51: 1 syngeneic, 24 sibling, 26 unrelated donor) HSCT. Itraconazole oral solution (n=58) was the most frequently used first line antifungal agent for prophylaxis and was administered for median 11 days. The most frequent cause of switch to micafungin was vomiting (n=42). The duration of neutropenia and micafungin administration was median 13 and 12 days, respectively. A successful outcome was achieved in 45 (75%) patients. Empirical antifungal therapy was initiated in 13 (22%) patients. There were 2 cases (3.3%) of breakthrough fungal infections which comprised a probable invasive pulmonary aspergillosis and a possible invasive fungal sinusitis. There was no case of invasive candidiasis. A total of 53 (88%) patients experienced at least one AE regardless of causality during micafungin administration. The most frequent AEs were hypokalemia, vomiting, diarrhea, and elevated serum aspartate aminotransferase or alanine aminotransferase. Among the aforementioned AEs, only 1 case of diarrhea could be classified as a probable relation with micafungin when causality was assessed. There was no AEs that caused discontinuation of micafungin. Conclusions: Micafungin seems to be a safe and effective agent for prophylaxis of IFIs including aspergillosis as well as candidiasis in HSCT recipients. However, further large, prospective, and randomized comparative studies are warranted for aspergillosis.

An active micro-mixer, which is composed of an oscillating micro-stirrer in the micro-channel to provide effective mixing was optimized. The effects of molecular diffusion and disturbance by the stirrer were considered with regard to two types of mixer models: the simple straight micro-channel and micro-channel with an oscillating stirrer. Two types of mixer models were studied by analyzing mixing behaviors such as their interaction after the stirrer. The mixing was calculated by Lattice Boltzmann methods using the D2Q9 model. In this study, the time-averaged mixing index formula was used to estimate the mixing performance of time-dependent flow. The mixing indices of the two models were compared. From the results, it was found that the mixer with an oscillating stirrer was much more enhanced' and stabilized. Therefore, an approximate optimization of an active micro-mixer with an oscillating stirrer was performed using Kriging method with OLHD (Optimal Latin Hypercube Design) in order to determine the optimal design variables. The design parameters were established as the frequency, the length and the angle of the stirrer. The optimal values were obtained as 1.5754, 0.803D and ±45°, respectively. It was found that the mixing index of the optimal design increased by 83.36% compared with that of the original design.

한일학생 및 일본 근로자에 대한 아침-저녁형과 수면습관에 대한 비교

한국대학생 533명 및 468명의 일본 대학생, 동일 연령대의 311명의 일본근로자에 대해 아침-저녁형 설문지 및 생활 습관 조사를 실시했다. 점수분포는 정규 분포였으나, 일본대학생 그룹은 약간 야간형으로 기울어진 분포를 보였다. 세 그룹 전부 기상시각 및 취침시각은 아침형,중간형,저녁형 순으로 늦었다. 그러나 일반적으로 한국대학생이 일본 대학생 보다 빠른 기상시각을 보였다. 근로자 집단은 학생보다 빠른 기상과 취침을 보였다. 세개 그룹 모두 아침형,중간형,저녁형 순으로 취침기상시각 및 수면시간의 변동성이 크고, 입면시각이 길고, 기상시 기분이 나빴다. 한국대학생이 일본 대학생 보다 약간 아침형으로 지우쳐 있지만 양국학생의 전반적인 수면습관은 비슷했다. 그리고 아침형 보다 저녁형의 수면 습관이 불규칙했다. 그리고 일본 근로자의 점수가 일본 학생 집단보다 약간 높고, 수면습관도 조금 달랐다. 이것은 사회생활의 제한으로 인한 수면습관의 변화가 M-E점수에 영향을 준다고 생각된다. The Morningness-eveningness questionnaire(MEQ) and life habits inventory were carried out with the three groups of 533 Korean students, 468 Japanese students, and 311 Japanese workers in the same age level. The distributions of score for these three groups look like normal, but the Japanese students distributions of is skewed to evening type. The self-reported waking times and bedtimes for the three groups was late the order of morning type, intermediate type, and evening type. However, generally the Korean students woke up earlier than the Japanese students. The workers always went to bed and woke up earlier than the students. For all the three groups, the variation in bedtime, waking time, and sleep length was large, the sleep latency was long, and the mood at waking was bad in the order of morning type, intermediate type, and evening type. The scores of the Korean student group on the questionnaire were distributed more to morning type than the Japanese student group, but sleep habits of the students of both countries were similar. The subjects of the evening type had more irregular sleep habits than those of the morning type. In comparison with the student group, the Japanese workers of the same age had higher scores on M-E and slightly different sleep habits. This means the change of sleep habits as a result of the demands of employment cause the change in the scores.

Normal feet have the longitudinal arch for the distribution of the weight. The longitudinal arch is known lateral and medial longitudinal arch. Collapsed arch of the foot is flat foot and it is the cause of the foot pain. Of course the low arch does not always make a foot problem in sports and daily activity. Longitudial foot arch is visible in the standing foot lateral radiograph, Harris mat and visual observation. In Radiographic study the lateral Talo-lst Metatarsal angle is known in standing foot lateral film. But the longitadinal medial arch is not correctly obtained in Talo-lst Metatarsal angle. So this study for Calcaneo-lst metatarsal angle in standing lateral foot radiograph is more valuable angle in medial longitadinl arch. And we do the study on difference in the longitadinal arch in normal weight versus overweight person.
