We performed dietary guidances for 15 male elite athletes (23±3 years of age) participating a training program for vigorous endurance run. Nutrient allowances for the athletes were determined by the guidelines of Japanese Dietary Allowances (5 th ed.), considering their physical activities at the highest level IV; total energy 3, 500 kcal, protein 140g, lipid 100g, carbohydrate 510g, calcium 1, 500 mg, iron 25 mg, vitamin A 8, 000 IU, thiamine 4.0 mg, riboflabin 5.0 mg and vitamin C 200 mg per day. We also developed food group allowances for the athletes based on their nutrient allowances and current young-aged Japanese dietary styles ; cereals 400 g, potatoes and starches 60 g, sugars 20 g fats and oils 30g, pulses 120g, meats 150g, fishes and shellfishes 150g, eggs 80g, milks 600g, green and yellow vegetables 300 g, the other vegetables 350 g, fruits 400 g and algae 20 g per day. For the experimental period of 45 days, daily diets adjusted to approximate 120% of the dietary allowances were served to the athletes who were free taking snacks and drinks. Dietary guidances for the athletes were assessed by monitors of their dietary intakes, physical constitution and clinical examinations in blood. Means of the dietary intakes of the athletes were 96-99% of the dietary allowances, determined by a nutritional survey with the 24 hrs recall method. There were less changes in the physical constitution of the athletes before, during and after the experimental period; body weight 57±2 kg and body fat 8.8 ± 2.4%. Values of the clinical marks in the blood of the athletes were maintained normally for a half year including the experimental period; red blood cells 507±9×104 cells/mm3, hemoglobin 15±0.4g/dl and hematocrit 46.6±0.7%.
It is concluded that suitable nutritional guidances and managements for young-aged male vigorous endurance runners lead good in their health and physical maintenances, which may have important consequences for their physical development as elite athletes.

PURPOSE: The neonatal mortality rate in Japan has currently been at the lowest level in the world. However, it is unclear whether there are still some potentially preventable neonatal deaths. We, therefore, aimed to examine the backgrounds of neonatal death and the possibilities of prevention in a region of Japan. MATERIALS AND METHODS: This is a population-based study of neonatal death in Shiga Prefecture of Japan. RESULTS: The 103 neonatal deaths in our prefecture between 2007 and 2011 were included. After reviewing by a peer-review team, we classified the backgrounds of these neonatal deaths and analyzed end-of-life care approaches associated with prenatal diagnosis. Furthermore, we evaluated the possibilities of preventable neonatal death, suggesting specific recommendations for its prevention. We analyzed 102 (99%) of the neonatal deaths. Congenital malformations and extreme prematurity were the first and the second most common causes of death, respectively. More than half of the congenital abnormalities (59%) including malformations and chromosome abnormality had been diagnosed before births. We had 22 neonates with non-intensive care including eighteen cases with congenital abnormality and four with extreme prematurity. Twenty three cases were judged to have had some possibility of prevention with one having had a strong possibility of prevention. Among specific recommendations of preventable neonatal death, more than half of them were for obstetricians. CONCLUSION: There is room to reduce neonatal deaths in Japan. Prevention of neonatal death requires grater prenatal care by obstetricians before birth rather than improved neonatal care by neonatologists after birth.

A special Students' Committee on Medical Education was established by the Student Union of Nippon Medical School. The members of this committee are all volunteers and have carried out several plans to improve the educational environment at our school. In 1999, the Students' Committee on Medical Education proposed holding joint meetings with the Education Committee of Nippon Medical School. The meeting was to allow communication between students and teachers for improving the curriculum. The volunteer faculty members of the Education Committee and students have held joint meetings seven times from November 1999 through February 2001. Discussions between students and teachers have changed ideas on both sides and have led to improvements in some educational programs, such as clinical internship during the summer vacation.

The human CCR4-NOT deadenylase complex consists of at least nine enzymatic and non-enzymatic subunits. Accumulating evidence suggests that the non-enzymatic subunits are involved in the regulation of mRNA deadenylation, although their precise roles remain to be established. In this study, we addressed the function of the CNOT1 subunit by depleting its expression in HeLa cells. Flow cytometric analysis revealed that the sub G(1) fraction was increased in CNOT1-depleted cells. Virtually, the same level of the sub G1 fraction was seen when cells were treated with a mixture of siRNAs targeted against all enzymatic subunits, suggesting that CNOT1 depletion induces apoptosis by destroying the CCR4-NOT-associated deadenylase activity. Further analysis revealed that CNOT1 depletion leads to a reduction in the amount of other CCR4-NOT subunits. Importantly, the specific activity of the CNOT6L immunoprecipitates-associated deadenylase from CNOT1-depleted cells was less than that from control cells. The formation of P-bodies, where mRNA decay is reported to take place, was largely suppressed in CNOT1-depleted cells. Therefore, CNOT1 has an important role in exhibiting enzymatic activity of the CCR4-NOT complex, and thus is critical in control of mRNA deadenylation and mRNA decay. We further showed that CNOT1 depletion enhanced CHOP mRNA levels and activated caspase-4, which is associated with endoplasmic reticulum ER stress-induced apoptosis. Taken together, CNOT1 depletion structurally and functionally deteriorates the CCR4-NOTcomplex and induces stabilization of mRNAs, which results in the increment of translation causing ER stress-mediated apoptosis. We conclude that CNOT1 contributes to cell viability by securing the activity of the CCR4-NOT deadenylase.

Methods: We investigated 154 foramina at L5–S1 in 77 patients. All the patients had degenerative lumbar disorders and had undergone both conventional MRI and 3D-MRI during the same visit. Differences between the FSRs calculated from conventional and 3D-MRI reconstructions and any correlations with the plain radiography findings were assessed. Results: In foramina that had a FSR of <50% on conventional MRI, the difference between the FSR obtained using conventional MRI and 3D-MRI was 5.1%, with a correlation coefficient of 0.777. For foramina with a FSR ≥50% on conventional MRI, the difference was 20.2%, with a correlation coefficient of 0.54. FSR obtained using 3D-MRI was significantly greater in patients who required surgery than in those who were successfully treated with conservative methods (88% and 42%, respectively). Segments with spondylolisthesis or lateral wedging showed higher FSRs than those without these conditions on both types of MRI. Conclusions FSRs <50% obtained using conventional MRI were sufficiently reliable; however, the results were inaccurate for FSRs ≥50%. Patients with high FSRs on 3D-MRI were more likely to require surgical treatment. Therefore, 3D-MRI is recommended in patients with suspected stenosis detected using conventional MRI or plain radiographs.

Background/Aims: The objective of this study was to elucidate the histological structure of the absent microsurface patterns (MSPs) that were visualized by magnifying endoscopy with narrow-band imaging (M-NBI). Methods: The study included consecutive gastric epithelial neoplasias for which M-NBI findings and histological findings could be compared on a one-to-one basis. The lesions were classified as absent MSPs and present MSPs based on the findings obtained using M-NBI. Of the histopathological findings for each lesion that corresponded to M-NBI findings, crypt opening densities, crypt lengths, crypt opening diameters, intercrypt distances, and crypt angles were measured and compared. Results: Thirty-six lesions were included in the analysis; of these, 17 lesions exhibited absent MSP and 19 lesions exhibited present MSP. Comparing the histological measurements for absent MSPs vs. present MSPs, median crypt opening density was 0.9 crypt openings/mm vs. 4.8 crypt openings/mm (p<0.001), respectively. The median crypt length, median crypt opening diameter, median intercrypt distance, and median crypt angle were 80.0 μm vs. 160 μm (p<0.001), 40.0 μm vs. 44.2 μm (p=0.09), 572.5 μm vs. 166.7 μm (p<0.001), and 21.6 degrees vs. 15.5 degrees (p<0.001), respectively. Conclusions Histological findings showed that lesions exhibiting absent MSPs had lower crypt opening density, shorter crypt length, greater intercrypt distance, and larger crypt angle.
