Lichen is a symbiotic mutualism of mycobiont and photobiont that harbors diverse organisms including endolichenic fungi (ELF). Despite the taxonomic and ecological significance of ELF, no comparative investigation of an ELF community involving isolation of a pure culture and high-throughput sequencing has been conducted. Thus, we analyzed the ELF community in Parmotrema tinctorum by culture and metabarcoding. Alpha diversity of the ELF community was notably greater in metabarcoding than in culture-based analysis. Taxonomic proportions of the ELF community estimated by metabarcoding and by culture analyses showed remarkable differences: Sordariomycetes was the most dominant fungal class in culture-based analysis, while Dothideomycetes was the most abundant in metabarcoding analysis. Thirty-seven operational taxonomic units (OTUs) were commonly observed by cultureand metabarcoding-based analyses but relative abundances differed: most of common OTUs were underrepresented in metabarcoding. The ELF community differed in lichen segments and thalli in metabarcoding analysis. Dissimilarity of ELF community intra lichen thallus increased with thallus segment distance; inter-thallus ELF community dissimilarity was significantly greater than intra-thallus ELF community dissimilarity. Finally, we tested how many fungal sequence reads would be needed to ELF diversity with relationship assays between numbers of lichen segments and saturation patterns of OTU richness and sample coverage. At least 6000 sequence reads per lichen thallus were sufficient for prediction of overall ELF community diversity and 50,000 reads per thallus were enough to observe rare taxa of ELF.

OBJECTIVE: To investigate simple radiographic findings on painful heels in ankylosing spondylitis (AS). Heel radiography in most studies was from AS patients' non-painful heel. METHODS: Seventy AS patients (34 bilateral cases) with heel pain at the time digital radiographs were taken were studied. Standing lateral views (104 radiographs) of the heel were reviewed. Associations between radiologic abnormalities and disease duration and among various abnormal findings were analyzed. RESULTS: Ninety-six (93.4%) had radiographic abnormalities (82.7% in soft tissues/61.5% in bone). Abnormalities of bone only were observed in 9.6%, of the soft tissues only in 30.8%, and of both were 51.9%. These included Kager's triangle's blurring (77.9%), posterior soft tissue swellings near the Achilles tendon insertion (65.4%), obliterations of the retrocalcaneal recess (65.4%), erosions of the superior pole of the posterior calcaneus (31.7%), subplantar irregular spurs (20.2%), posterior traction spurs (16.3%), subplantar erosions (14.4%) and cortical thickenings of the inferior calcaneal body (5.8%). There was a significant association between swelling in the posterior soft tissue and obliteration of the retrocalcaneal recess (p<0.001). CONCLUSION: Digital radiography in AS is useful for observing not only bony lesions but also soft tissue abnormalities of the heel, particularly of the posterior heel. For assessing the symptomatic enthesitis of the Achilles, this simple and quick diagnostic tool is valuable when examining for soft tissues' alterations of the posterior heel.

BACKGROUND: It has been well demonstrated that trypsin inhibitor can stimulate the secretion of cholecystokinin. Camostat mesylate (C20H22N4O5 CH3SO3H) is a synthetic trypsin inhibitor. We demonstrated the effect of camostat mesylate on the chemical composition of bile and the crystallization in gallbladder-stone patients. METHODS: Gallbladder bile sample from 22 patients with GB stones were analyzed. In 11 patients, camostat mesylate (Foy-pan ) was administered orally in a dosage of 600 mg per day for more than 5 days, and the results of the bile analysis were compared to those of 11 controls. RESULTS: The total protein concentration in the camostat group was lower than that in control group (0.21+/-0.10 vs 0.24+/-0.06 g/dl) but the difference was not significant (p=0.41). The total bile acid concentration in the camostat group was significantly lower than that in the control group (5.47+/-1.56 vs 6.85+/-1.32 g/dl, p=0.04). The concentrations of cholesterol and phospholipid were lower in the camostat group (0.35 +/- 0.19 vs 0.44 +/- 0.11 g/dl, 2.10 +/- 1.19 vs 2.92 +/- 0.93, respectively), but the differences were not statistically significant (p=0.20, p=0.09, respectively). The total lipid concentration which reflects the concentrated magnitude of the bile, was significantly lower in the camostat group (7.93 +/- 2.87 vs 10.20 +/- 2.01 g/dl, p=0.04). The cholesterol saturation index didn't demonstrate a significant difference between the two groups (1.06 +/- 0.27 vs 0.95 +/- 0.31, p=0.38). Crystallization in the bile from cholesterol stone patients, was observed every day for 7 days. Crystallizations was less frequent in the camostat group, but the difference was not statistically significant (1/6 vs 4/8, p=0.39). DISIDA (disofenin iminediacetate) scans were performed in 3 healthy volunteers to observe the changes in the radioactivities and the volumes of the gallbladders before and after the administrations of camostat. The peak radioactivities, the transittime to the peak radioactivity, and the gallbladder volume at the peak radioactivity in the scan after the administration of camostat were lower than in the corresponding values before the administration. CONCLUSIONS: Camostat mesylate lowers the concentration of all bile components. We assume that the effects of Camostat mesylate are mediated by CCK, which enhances gallbladder motility and limits the concentrating function of the gallbladder.

PURPOSE: The purpose of this study was to compare the outcomes of osteosynthesis using compression hip screw fixation versus bipolar hemiarthroplasty in AO type A2 intertrochanteric fractures. MATERIALS AND METHODS: From March 2003 to December 2009, 89 patients were included in this study. They were treated using compression hip screws (43 cases) or bipolar hemiarthroplasty (46 cases). The mean age of patients was 77.7 years (65-94 years) and the mean follow-up period was 5.9 years (1-8.3 years). For comparison of the outcomes in the two groups, statistical analyses were performed with parameters including anesthesia time, operation time, amount of transfusion, hospital stay, general complications, clinical outcome, time of partial weight-bearing using a walker, and radiological failure rate. RESULTS: Differences in the amount of transfusion, general complications, and clinical outcome (Merle d'Aubigne and Postel score) were not statistically significant between the two groups. The bipolar hemiarthroplasty group showed better results than the compression hip screw group for anesthesia time and the time of partial weight-bearing using a walker. Radiological failures were observed in hips in one case (2.2%) of bipolar hemiarthroplasty, and in four cases (9.3%) of compression hip screw fixation. CONCLUSION: Among elderly individuals with AO type A2 intertrochanteric fractures, patients treated with bipolar hemiarthroplasty were able to perform early ambulation. However, no significant difference in operation time, amount of postoperative transfusion, clinical results, hospital stay, and radiological failure rate was observed between the bipolar hemiarthroplasty and compression hip screw fixation groups.

BACKGROUND: Detection of postoperative spinal cord level change can provide basic information about the spinal cord status, and electrophysiological studies regarding this point should be conducted in the future. METHODS: To determine the changes in the spinal cord level postoperatively and the possible associated factors, we prospectively studied 31 patients with scoliosis. All the patients underwent correction and posterior fusion using pedicle screws and rods between January 2008 and March 2009. The pre- and postoperative conus medullaris levels were determined by matching the axial magnetic resonance image to the sagittal scout image. The patients were divided according to the change in the postoperative conus medullaris level. The change group was defined as the patients who showed a change of more than one divided section in the vertebral column postoperatively, and the parameters of the change and non-change groups were compared. RESULTS: The mean pre- and postoperative Cobb's angle of the coronal curve was 76.80degrees +/- 17.19degrees and 33.23degrees +/- 14.39degrees, respectively. Eleven of 31 patients showed a lower conus medullaris level postoperatively. There were no differences in the pre- and postoperative magnitude of the coronal curve, lordosis and kyphosis between the groups. However, the postoperative degrees of correction of the coronal curve and lumbar lordosis were higher in the change group. There were also differences in the disease entities between the groups. A higher percentage of patients with Duchene muscular dystrophy had a change in level compared to that of the patients with cerebral palsy (83.3% vs. 45.5%, respectively). CONCLUSIONS: The conus medullaris level changed postoperatively in the patients with severe scoliosis. Overall, the postoperative degree of correction of the coronal curve was higher in the change group than that in the non-change group. The degrees of correction of the coronal curve and lumbar lordosis were related to the spinal cord level change after scoliosis correction.

OBJECTIVES: Previous studies have suggested that some personality characteristics are associated with the onset, prognosis and social function in schizophrenia patients. However few is known about the personality and affective characteristic of genetic high risk group (GHR) for schizophrenia. This study aimed to investigate the personality and the affective characteristic of GHR group for schizophrenia. METHODS: Participants were 54 healthy controls (HC), 26 subjects with GHR for schizophrenia and 28 subjects with first episode psychosis (FEP). We performed three self-report questionnaires; NEO-Personality Inventory-Revised, State and Anger Expression Inventory and Positive Affect and Negative Affect Schedule. RESULTS: The GHR group showed higher score in agreeableness item than the HC (p=0.028). In extraversion item, the FEP group showed significantly lower scores than the HC (p=0.001). The GHR group showed lower scores in neuroticism item compared with FEP group in trend level. The FEP group showed higher trait-anger, lower positive affect and higher negative affect compared with the others. CONCLUSION: The GHR group seem to share certain vulnerable personality and affective characteristics for schizophrenia with the FEP group. On the other hands, the GHR group appeared to be more agreeable than the other groups, which might act as the compensation for other impaired functions.

OBJECTIVE: To evaluate the usefulness of alendronate for prevention and treatment of postmenopausal osteoporosis this study was taken. METHODS: This prospective randomized clinical trial examined the effects of oral alendronate and HRT(conjugated estrogen plus medroxyprogesterone acetate), in combination and seperately, on BMD, biochemical markers of bone turnover in 79 women with low bone mass. Treatment included alendronate(10mg daily) plus HRT(group I, n=38), or HRT(group II, n=41) for 6 months. Bone density measurements were performed at months 0 and 6 at the lumbar spine. Biochemical markers of bone turnover were also measured every three months. RESULTS: Serum Osteocalcin decreased by 19.2% in group I and by 10.0% in group II at 3 months(p<0.05), and by 30.9% in group I and by 19.8% in group II at 6 months(p<0.05). Urinary deoxypyridinoline showed decrease of 19.75%(I) vs. 10.4%(II) at 3 months, 30.1%(I) vs. 20.7%(II) at 6 months, the difference was significant. Percent change of BMD measurements from baseline at 6 months in group I was 6.2% and in group II 0.6% on the lumbar spine(p<0.05). CONCLUSION: The treatment with alendronate is useful to postmenopausal women with osteoporosis by decreasing bone turnover markers, and by increasing the BMD.

OBJECTIVE: The objective of this study was to investigate the effects of miniscrew-assisted rapid palatal expansion (MARPE) on changes in airflow in the upper airway (UA) of an adult patient with obstructive sleep apnea syndrome (OSAS) using computational fluid-structure interaction analysis. METHODS: Three-dimensional UA models fabricated from cone beam computed tomography images obtained before (T0) and after (T1) MARPE in an adult patient with OSAS were used for computational fluid dynamics with fluid-structure interaction analysis. Seven and nine cross-sectional planes (interplane distance of 10 mm) in the nasal cavity (NC) and pharynx, respectively, were set along UA. Changes in the cross-sectional area and changes in airflow velocity and pressure, node displacement, and total resistance at maximum inspiration (MI), rest, and maximum expiration (ME) were investigated at each plane after MARPE. RESULTS: The cross-sectional areas at most planes in NC and the upper half of the pharynx were significantly increased at T1. Moreover, airflow velocity decreased in the anterior NC at MI and ME and in the nasopharynx and oropharynx at MI. The decrease in velocity was greater in NC than in the pharynx. The airflow pressure in the anterior NC and entire pharynx exhibited a decrease at T1. The amount of node displacement in NC and the pharynx was insignificant at both T0 and T1. Absolute values for the total resistance at MI, rest, and ME were lower at T1 than at T0. CONCLUSIONS: MARPE improves airflow and decreases resistance in UA; therefore, it may be an effective treatment modality for adult patients with moderate OSAS.
