Butterfly fauna in the Higashi-Hiroshima Campus, Hiroshima University

東広島キャンパスのチョウ相を把握するために，2015年の4月から11月にかけてルートセンサス法によるチョウの調査を行った。本調査では5科56種のチョウを確認した。さらに調査期間外に10種のチョウを確認した。合計すると東広島キャンパスで5科66種のチョウを確認した。区域によって出現する種が異なるが，自然区と隣接する圃場で最も多くの種を確認した。以前の調査結果と比較すると，キャンパスの環境が変化した可能性が示唆された。We investigated the butterfly fauna in the Higashi-Hiroshima campus of Hiroshima University using route census surveys conducted from April to November 2015. Fifty-six species belonging to five families were recorded in this study. Ten additional species were found outside the survey period, which resulted in the detection of 66 species of butterflies (five families). The species richness was the highest in the farm field adjacent to the natural forest; however, the detected butterfly species differed from one area to another. Considering previous surveys made in this campus, the present results suggested slight environmental changes in and around the Higashi-Hiroshima campus

Impact of ganglionated plexi ablation on high-frequency stimulation-induced changes in atrial fibrillation cycle length in the pulmonary vein

AbstractBackgroundWe assessed high-frequency stimulation (HFS)-induced changes in the atrial fibrillation (AF) cycle length (AFCL) in the pulmonary vein (PV) after ganglionated plexi (GP) ablation.MethodsTwenty-two patients undergoing catheter ablation for AF were retrospectively enrolled. Sites showing a vagal response (VR) to HFS were defined as GP-positive sites. AFCL was determined in the adjacent PV, distant PV, coronary sinus, and right atrium. Twenty cycles were counted before and after each HFS. After radiofrequency application to the GP site, HFS was repeated.ResultsAt GP-positive sites (n=57), significant shortening of the AFCL was detected in the adjacent PV (17% shortening, 165±38 to 137±27ms, p<0.001) and distant PV (4.8% shortening, p<0.001), but not in the coronary sinus (0.8% shortening, p=0.27) or right atrium (1.8% shortening, p=0.06). However, no significant shortening was observed at GP-negative sites (n=25). At 41 of the 57 sites where VR disappeared after a single radiofrequency application, no significant shortening was observed in the adjacent PV (2.1% shortening, p=0.25). At 16 of the 57 sites where VR was still present, significant shortening was observed in the adjacent PV (16% shortening, p<0.001).ConclusionsHFS of the GP has a strong influence on AFCL in the PV

臨床用CTを用いた上腕骨大結節の領域別骨梁微細構造解析

BACKGROUND: In arthroscopic surgery, the suture anchor technique has become popular for rotator cuff repair. Preoperative evaluation of the bone microstructure is of utmost importance because, especially in elderly patients, osteoporotic changes may cause anchor pullout, which results in failure of rotator cuff repair. Many groups have reported humeral microstructural analysis; however, most studies were experiments using porcine specimens or human cadavers. In this study, we used multidetector row computed tomography to successfully perform in vivo evaluation of the bone microstructure of the humeral greater tuberosity in patients with rotator cuff tears. METHODS: Ten patients were examined. Regions of interest were defined in six quadrants of the greater tuberosity (medial, lateral, and far lateral rows of the anterior and posterior areas). The local bone mineral density and the trabecular microstructural parameters, including the mean bone volume to total volume (BV/TV), trabecular thickness, trabecular separation, and structure model index (SMI), were measured using bone analysis software. RESULTS: The BV/TV of the posteromedial region was highest and the SMI of the posteromedial region was lowest. These findings suggest that the bone quality of the posteromedial portion is the highest within the greater tuberosity. CONCLUSION: Because the bone quality may be correlated with the pullout strength of suture anchors, our method can help to understand the individual and regional variance in bone quality and may lead to the creation of personalized surgical protocols.博士（医学）・乙第1360号・平成27年5月28日© 2014 Sakamoto et al.; licensee BioMed Central Ltd.

Profile of Blood Glucose in Diabetic Patient Suffered from Diabetic Foot Osteomyelitis with Effective Low Carbohydrate Diet

The case was 52-year-old female with type 2 diabetes mellitus (T2DM) for 10-years. She complained of the decreased sensation of right lower foot, and revealed diabetic foot infection (DFI) and/or diabetic foot osteomyelitis (DFO) at right 1st proximal phalanx. Various data included body mass index (BMI) 33.3 kg/m2, HbA1c 11.4%, blood glucose 430 mg/dL, WBC 12100 /μL, C-reactive Protein (CRP) 13.5 mg/dL. On admission (day 1), she was started by 4 times of injection (Aspart and Glargin) with glucose profile 200-500 mg/dL. Surgical amputation of the right toe was performed between 1st metatarsal and proximal phalanx (day 17). Then, blood glucose profile decreased moderately. After discharge of the hospital, super-Low Carbohydrate Diet (LCD) was started without Aspart (day 37). Consequently, glucose profile was normalized with HbA1c 6.3% on (day 77). Consequently, LCD was evaluated to be effective for glucose variability in this case and some related discussion was described

Joint field experiments for comparisons of measuring methods of photosynthetic production

During the 1st GAP Workshop at Konstanz in April 1982 comparative measurements of phytoplankton primary production by several techniques were conducted simultaneously at an offshore station in Lake Konstanz and an experimental algal pond. Suspended glass bottle exposure techniques using 14C and 13C uptake gave Pz (mg C m−3 h−1) values which varied considerably near-surface, but estimates of areal rates for the euphotic zone ΣPcu(mg C m−3 h−1) which were reasonably close. In the lake, ΣPz, from a vertical tube exposure (with 14C uptake) was greater than rates derived for integrated bottle samples. The oxygen bottle method permitted a good estimate of compensation depth, corresponding to in situ growth studies. There were difficulties in direct comparison between O2 and carbon methods. Correlation between them for Pz was good in the lake but poor in the pond, both for suspended bottle and vertical tube methods. This series demonstrates that despite reasonable overall estimates, comparatively minor methodological differences in experimental technique can cause large variatio

Abnormal Cystatin C Levels in Two Patients with Bardet-Biedl Syndrome

Bardet-Biedl syndrome (BBS) is an autosomal recessive disorder characterized by central obesity, mental impairment, rod-cone dystrophy, polydactyly, hypogonadism in males, and renal abnormalities. The causative genes have been identified as BBS1-14. In the Western countries, the prevalence of this disease ranges from 1/13,500 to 1/160,000, while only a few Japanese patients have been reported in the English-language literature. The incidence of renal dysfunction or anomalies in previous reports varies considerably ranging from ∼20% to universal occurrence. We here report that two Japanese patients who had BBS with normal BUN and creatinine levels had elevated levels of cystatin C, a sensitive marker of glomerular filtration rate. A urine albumin level increased only in the elder patient. Thus, cystatin C may be useful for detecting renal abnormalities in patients with an apparent normal renal function. Because this disease is diagnosed by accumulation of symptoms, such a sensitive marker might help early diagnosis of BBS
