Abstract
BACKGROUND AND PURPOSE Selective voluntary motor control is an important factor influencing gross motor function, interjoint coordination, and the outcome of hamstring-lengthening surgery in spastic cerebral palsy. Using DTI, we investigated whether selective voluntary motor control would show strong correlations with WM motor tract microstructure and whether selective voluntary motor control is more sensitive to global WM impairment than gross motor function. MATERIALS AND METHODS Children with spastic bilateral cerebral palsy born preterm and typically developing children were recruited. The Selective Control Assessment of the Lower Extremity (SCALE) and Gross Motor Function Measure (GMFM) were assessed in participants with cerebral palsy. Participants underwent brain MR imaging to collect DWI data. Tract-Based Spatial Statistics was used to analyze the WM for between-group differences and correlations with SCALE and GMFM. ROI analyses compared motor regions. RESULTS Twelve children with cerebral palsy (mean age, 11.5 years) and 12 typically developing children (mean age, 10.3 years) participated. Altered DTI outcomes were found throughout the whole brain for the cerebral palsy group. SCALE, developed to evaluate selective voluntary motor control in cerebral palsy, showed significant positive correlations with fractional anisotropy in more WM voxels throughout the whole brain and for motor regions, including the corticospinal tract and corpus callosum, compared with GMFM. A significant negative correlation between radial diffusivity and SCALE, but not GMFM, was found within the corpus callosum. CONCLUSIONS SCALE was a more sensitive clinical correlate of motor and whole-brain WM tract impairment in children with spastic bilateral cerebral palsy, suggesting greater anisotropy and myelination in these regions for those with higher selective voluntary motor control.

Abstract
The radiative cooling of highly excited carbon cluster cations of sizes N = 8, 10, 13-16 has been studied in an electrostatic storage ring. The cooling rate constants vary with cluster size from a maximum at N = 8 of 2.6 × 104 s-1 and a minimum at N = 13 of 4.4 × 103 s-1. The high rates indicate that photon emission takes place from electronically excited ions, providing a strong stabilizing cooling of the molecules.

Abstract
PURPOSE Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a technique for temporary stabilization of patients with non-compressible torso hemorrhage. This technique has been increasingly used worldwide during the past decade. Despite the good outcomes of translational studies, clinical studies are divided. The aim of this multicenter-international study was to capture REBOA-specific data and outcomes. METHODS REBOA practicing centers were invited to join this online register, which was established in September 2014. REBOA cases were reported, both retrospective and prospective. Demographics, injury patterns, hemodynamic variables, REBOA-specific data, complications and 30-days mortality were reported. RESULTS Ninety-six cases from 6 different countries were reported between 2011 and 2016. Mean age was 52 ± 22 years and 88% of the cases were blunt trauma with a median injury severity score (ISS) of 41 (IQR 29-50). In the majority of the cases, Zone I REBOA was used. Median systolic blood pressure before balloon inflation was 60 mmHg (IQR 40-80), which increased to 100 mmHg (IQR 80-128) after inflation. Continuous occlusion was applied in 52% of the patients, and 48% received non-continuous occlusion. Occlusion time longer than 60 min was reported as 38 and 14% in the non-continuous and continuous groups, respectively. Complications, such as extremity compartment syndrome (n = 3), were only noted in the continuous occlusion group. The 30-day mortality for non-continuous REBOA was 48%, and 64% for continuous occlusion. CONCLUSIONS This observational multicenter study presents results regarding continuous and non-continuous REBOA with favorable outcomes. However, further prospective studies are needed to be able to draw conclusions on morbidity and mortality.

Abstract
Objective Guided self-help treatments based on cognitive behavioral therapy (CBT-GSH) are regarded as a first-line effective treatment for bulimia nervosa (BN). With limited application for CBT-GSH in Japanese clinical settings, we conducted a single arm pilot study in order to confirm the acceptability and availability of CBT-GSH in Japan. Results 25 women with BN received 16–20 sessions of face-to-face CBT-GSH. Primary outcomes were the completion rate of intervention and abstinence rates from objective bingeing and purging as assessed by the Eating Disorder Examination. Secondary outcomes were other self-report measurements of the frequency of bingeing and purging, and characteristic psychopathologies of eating disorders. Assessments were conducted before CBT as baseline as well as after CBT. 92% (23/25) of the participants completed the CBT sessions. After CBT-GSH, 40% (10/25) of the participants (intention-to-treat) achieved symptom abstinence. The mean binge and purge episodes during the previous 28 days improved from 21.88 to 10.96 (50% reduction) and from 22.44 to 10.88 (52% reduction), each (before CBT-GSH to after CBT-GSH), and the within-group effect sizes were medium (Cohen’s d = 0.67, 0.65, each). Our study provided a preliminary evidence about the feasibility of CBT-GSH in Japanese clinical settings for the future. Trial registration This study was registered retrospectively in the national UMIN Clinical Trials Registry on July 10, 2013 (registration ID: UMIN000011120)

Abstract
PURPOSE The aim of this study is to evaluate the early survival and organ damage following 30 and 60 min of thoracic resuscitative endovascular balloon occlusion of the aorta (REBOA) in an ovine model of severe hemorrhagic shock. METHODS Eighteen sheep were induced into shock by undergoing a 35 % controlled exsanguination over 30 min. Animals were randomized into three groups: 60-min REBOA 30 min after the bleeding (60-REBOA), 30-min REBOA 60 min after the bleeding (30-REBOA) and no-REBOA control (n-REBOA). Resuscitation with crystalloids and whole blood was initiated 20 and 80 min after the induction of shock. Animals were observed for 24 h with serial potassium and lactate measurements. Autopsy was performed to evaluate organ damage. RESULTS Two animals of the n-REBOA group died within 90 min of shock induction; no hemorrhagic deaths were observed in the REBOA groups. Twenty-four-hour survival for the 60-, 30-, and n-REBOA groups was 0/6, 5/6, and 4/6 (P = 0.002). In 60-REBOA, potassium and lactate were increased at 270-min time point: from 4.3 to 5.1 mEq/l and from 3.7 to 5.1 mmol/L, respectively. Both these values were significantly higher than in the n-REBOA group (P = 0.029 for potassium and P = 0.039 for lactate). Autopsy revealed acute tubular necrosis in all died REBOA group animals. CONCLUSIONS In this ovine model of severe hemorrhagic shock, REBOA can be used to prevent early death from hemorrhage; however, 60 min of occlusion results in significant metabolic derangement and organ damage that offsets this gain.

Abstract
This article proposes an innovative concept of interventional radiology for hemodynamically unstable trauma patients. Damage control interventional radiology (DCIR) is an aggressive and time-conscious algorithm that prioritizes saving life of the hemorrhaging patient in extremis which conventional emergency interventional radiology (CEIR) cannot efficiently do. Briefly, DCIR aims to save life while CEIR aims to control bleeding with a constant concern to time-awareness. This article also presents the concept of "Prompt and Rapid Endovascular Strategies in Traumatic Occasions" (PRESTO) that entirely oversees and manages trauma patients from arrival to the trauma bay until initial completion of hemostasis with endovascular techniques. PRESTO's "Start soon and finish sooner" relies on the earlier activation of interventional radiology team but also emphasizes on a rapid completion of hemostasis in which DCIR has been specifically tailored. Both DCIR and PRESTO expand the role of IR and represent a paradigm shift in the realm of trauma care.

Abstract
We provide the experimental evidence that the single electron capture process in slow collisions between O^{3+} ions and neon dimer targets leads to an unexpected production of low-energy electrons. This production results from the interatomic Coulombic decay process, subsequent to inner-shell single electron capture from one site of the neon dimer. Although pure one-electron capture from the inner shell is expected to be negligible in the low collision energy regime investigated here, the electron production due to this process overtakes by 1 order of magnitude the emission of Auger electrons by the scattered projectiles after double-electron capture. This feature is specific to low charge states of the projectile: similar studies with Xe^{20+} and Ar^{9+} projectiles show no evidence of inner-shell single-electron capture. The dependence of the process on the projectile charge state is interpreted using simple calculations based on the classical over the barrier model.

Abstract
Electron capture processes for low energy Ar(9+) ions colliding with Ar(2) dimer targets are investigated, focusing attention on charge sharing between the two Ar atoms as a function of the molecular orientation and the impact parameter. A preference for charge-asymmetric dissociation channels is observed, with a strong correlation between the projectile scattering angle and the molecular ion orientation. The measurements here provide clear evidence that projectiles distinguish each atom in the target and that electron capture from near-site atoms is favored. Monte Carlo calculations based on the classical over-the-barrier model, with dimer targets represented as two independent atoms, are compared to the data. They give new insight into the dynamics of the collision by providing, for the different electron capture channels, the two-dimensional probability maps p(b), where b is the impact parameter vector in the molecular frame.

Abstract
We report conclusive evidence of an efficient cooling mechanism via the electronic radiative transitions of hot small molecular anions isolated in vacuum. We stored C6(-) and C6H(-) in an ion storage ring and observed laser-induced electron detachment with delays up to several milliseconds. The terminal hydrogen atom caused a drastic change in the decay profiles. The decay of photoexcited C6H(-) is slow and nonexponential, which can be explained by depletion cooling, whereas that for C6(-) occurs extremely fast, on a time scale below 0.1 ms and can only be explained by electronic radiative cooling via low-lying electronic excited states.

Abstract
Faecal samples were collected from the rectum of 540 domestic dogs from four districts (Lusaka, Katete, Petauke and Luangwa) in Zambia between 2005 and 2006 and prevalences of canine alimentary tract parasites were determined by coprological examination. Thirteen different ova and parasites including strongyle (43.3%), Spirocerca lupi (18.7%), taeniid (13.1%), Toxocara canis (7.6%), Sarcocystis sp.* (7.5%), Isospora sp.* (5.7%), Physaloptera sp.* (4.6%), Capillaria sp.* (2.8%), Dipylidium caninum (2.2%), Mesocestoides sp.* (2.0%), Ascaris sp.* (1.7%), Trichuris vulpis* (0.4%) and Schistosoma mansoni* (0.4%) were detected, Ascaris and Schistosoma probably originating from coprophagy. The species with asterisks and later-described Taenia multiceps are for the first time reported from dogs in Zambia. A coproantigen enzyme-linked immunosorbent assay (CoproAg-ELISA) developed for Echinococcus spp. revealed 43 positive dogs and 37 of these harboured taeniid eggs. From 63 of the 71 taeniid egg-positive samples, eggs and DNA thereof were isolated and subjected to a multiplex polymerase chain reaction for differentiating E. granulosus sensu lato, E. multilocularis and Taenia spp. Amplicons indicative for Taenia spp. were obtained from 60 samples. Sequencing of amplicons spanning part of the mitochondrial cytochrome c oxidase subunit 1 gene, which was possible with 38 samples, revealed 35 infections with T. hydatigena and 3 with T. multiceps. Therefore, the CoproAg-ELISA showed some positives, but concrete evidence for the existence of canine E. granulosus infection could not be established. Comparison of the results of the CoproAg-ELISA and Taenia species identification indicated that the CoproAg-ELISA cross-reacts with patent infections of T. hydatigena (57%) and T. multiceps (33%).

Abstract
The typical imaging findings of neonatal non-ketotic hyperglycinemia have rarely been described in the radiologic literature with only few individual cases or small series reported. In this article, we present a case of neonatal onset non-ketotic hyperglycinemia, imaged at 6 days of age, and discuss characteristic MRI and MR spectroscopic findings.

Abstract
340 Background: Gallbladder cancer (GBC) is one of the most common malignancies of the biliary tract. Because of the lack of specific presentations, this condition is frequently diagnosed only at an advanced stage. Obstructive jaundice is generally regarded as an indicator of far advanced disease, unresectability, and poor prognosis. The aim of this study was to evaluate clinicopathological factors, especially jaundice, influencing outcome after radical resection of gallbladder cancer, in order to identify the patients benefiting from radical surgery. Methods: Seventy-five patients with GBC underwent surgical resection between 1998 and 2008. A retrospective analysis was conducted on sixty-four patients with UICC T2 or more tumors. Clinicopathologic features, extents of resection, and survival rates were investigated retrospectively. Obstructive jaundice was defined that serum T-bil level was more than 2.0 mg/ml. Patients with jaundice underwent ENBD or PTBD and curative resection was performed when serum T-Bil level decreased below 2.0 mg/ml. Right after laparotomy, para-aortic lymphadenectomy and frozen section pathology were performed to convert a radical resection to a palliative procedure when a para-aortic lymph node was positive. Results: The three and five-year disease-specific survival rates were 47% and 41%, respectively. Nine patients survived for more than five years.Univariate analysis showed that blood loss during operation, hepatic invasion, portal vein invasion, N category, M category after postoperative pathological examination and residual tumor were significant prognostic factors (p<0.05), but multivariate analysis showed that M category only was independent prognostic factor (p<0.05). Five-year disease-specific survival rates for patients with (n=37) and without (n=27) obstructive jaundice were 47% and 35%, respectively (p=0.69). Conclusions: Obstructive jaundice had no impact on postoperative survival as long as metastatic disease was exclueded and adequate resection of the hepatic hilum was performed. Aggressive surgery might bring long-term survival in selected patients even with obstructive jaundice by advanced gallbladder cancer. No significant financial relationships to disclose.

Abstract
We measured kinetic energies of the fragment ions of argon dimers multiply ionized by low-energy Ar(9+) collisions. For (Ar2)(4+) dissociation, the asymmetric channel (Ar(3+) + Ar(+)) yield is found unexpectedly higher than the symmetric channel (Ar(2+) + Ar(2+)) yield in contrast with previous observation for covalent molecules or clusters. For the dissociation channel (Ar2)(2+)→Ar(+) + Ar(+), two well-separated peaks were observed, clearly evidencing that the direct Coulombic dissociation and the radiative charge transfer followed by ionic dissociation alternatively occur for the dicationic dimers. The respective intensity of these two peaks provides a direct mean to unravel the respective proportion of one-site and two-site double-electron capture, which are found equal for this collision system.

Abstract
Kinetics of the degradation of olive oil by an acclimated activated sludge were studied. Kinetic constants for the lipid removal from the mixed liquor and for that from the supernatant and for the hydrolysis step were evaluated using Michelis-Menten equations. The maximum specific reactions rates (v(max)) and the saturation constants (K(m)) were v(max) = 1.20 mg lipid mg(-1) MLVSS day(-1) and K(m) = 1290 mg/L for lipid removal from the mixed liquor; v(max) = 1.54 mg lipid mg(-1) MLVSS day(-1) and K(m) = 801 mg/L for that from the supernatant; v(max) = 1.57 mg olive oil mg(-1) MLVSS day(-1) and K(m) = 1750 mg/L for the hydrolysis of olive oil (where MLVSS refers to mixed liquor volatile suspended solids). The adsorption of olive oil by the activated sludge contributed to the lipid removal from the supernatant. The specific rate of this adsorption was also estimated. The hydrolysis, rather than the oxidation of free fatty acids, was the rate limiting step in the degradation of olive oil when the concentration of olive oil was lower than about 800 mg/L.

Abstract
The cooling rates of C60- have been measured in an electrostatic storage ring between several hundred mus and several tens of ms with one-photon laser excitation. The absolute energy scale is established by the photon energy, and the cooling time interval is derived from the nonexponential decay of the ensemble of hot molecules. The energy decreases due to the combined action of depletion and thermal emission of IR photons with a total energy loss rate that varies inversely proportional to time, 0.9 eV/t. The radiative component decreases from a few hundred eV/s at submillisecond time scales to several tens of eV/s at 20 ms and confirms that the crossover from depletion to predominantly radiative cooling occurs around 5 ms. The method is applicable to any large molecule or cluster which decays spontaneously, irrespective of the specific decay channel.

Abstract
This article presents a new type of low-energy crossed-beam electron spectrometer for measuring angular differential cross sections of electron-impact excitation of atomic and molecular targets. Designed for investigations at energies close to excitation thresholds, the spectrometer combines a pulsed electron beam with the time-of-flight technique to distinguish between scattering channels. A large-area, position-sensitive detector is used to offset the low average scattering rate resulting from the pulsing duty cycle, without sacrificing angular resolution. A total energy resolution better than 150 meV (full width at half maximum) at scattered energies of 0.5-3 eV is achieved by monochromating the electron beam prior to pulsing it. The results of a precision measurement of the differential cross section for electron-impact excitation of helium, at an energy of 22 eV, are used to assess the sensitivity and resolution of the spectrometer.

Abstract
The patient was a 54-year-old female with both headache and vomit presented to the emergency room. Endoscopic examination revealed an advanced esophageal cancer located on the middle thoracic esophagus. Histological analysis revealed squamous cell carcinoma. The clinical stage was diagnosed as T4N2M0 and this case was treated by the chemoradiation. She presented progressive moist cough after chemoradiotherapy. Esophagography demonstrated esophago-bronchial fistula (EBF). EBF was not detected by routine broncoscopy. To confirm fistula, we were performed the bronchoscopy which utilized an indocyanine green. Contrast media colored green were over from the superior segmental bronchus in a bronchoscope. The bronchoscope which utilized an indocyanine green is effective for EBF.

Abstract
The T-cell-mediated immune response exhibits a crucial function in the control of the intrahepatic proliferation of Echinococcus multilocularis larvae in mice and humans, both being natural intermediate hosts of the parasite. Antigen B (AgB), a metabolized Echinococcus spp. lipoprotein, contributes to the modulation of the T-cell immune response, and distinct sites of the corresponding AgB1, AgB3 and AgB4 genes were shown to be under positive selection pressure. Since several AgB gene variants are present in a single Echinococcus metacestode, we used secondary E. multilocularis infections in BALB/c and in athymic nude mice (devoid of T-cell responses) to analyze the effect of the cellular immune response on the expression and diversity of EmAgB1-EmAgB4 genes. We demonstrated hereby that EmAgB transcripts were less abundant in nude mice during the early phase of infection (at one month post-infection), and that EmAgB2 is simultaneously down-regulated when compared to the other three genes. A negative relationship exists between the level of transcription and diversity of EmAgB genes. Moreover, no excess of non-synonymous substitutions was found among the distinct EmAgB alleles from a single host. Together, these results pointed to the effect of purifying selection, which seemed to eliminate the detrimental AgB variants generated during the development of the metacestode within the peritoneal cavity of its intermediate host.

Abstract
The present study aimed to search for and characterize parasite molecules, whose expression levels correlate with the viability and growth activity of Echinococcus multilocularis metacestodes. We focused on the expression profiles of 2 parasite-derived genes, 14-3-3 and II/3-10, as putative molecular markers for viability and growth activity of the larval parasite. In experiments in vivo, gene expression levels of 14-3-3 and II/3-10 were relatively quantified by real-time reverse transcription-PCR using a housekeeping gene, beta-actin, as a reference reaction. All three reactions were compared with growth activity of the parasite developing in permissive nu/nu and in non-permissive wild type BALB/c mice. At 2 months p.i., the transcription level of 14-3-3 was significantly higher in parasites actively proliferating in nu/nu mice compared to parasites moderately growing in wild type mice. Immunoblotting experiments confirmed at the protein level that 14-3-3 was over-expressed in parasites derived from nu/nu mice at 2 months p.i. In vitro treatment of E. multilocularis with an anti-echinococcal drug nitazoxanide resulted in a significant decrease of both 14-3-3 and II/3-10 transcription levels found after 8 days of treatment, which correlated with the kinetics of a housekeeping gene, beta-actin. The conclusion is that 14-3-3, combined with II/3-10, exhibits good potential as a molecular marker to assess viability and growth activity of the parasite.

Abstract
A 68-year-old male was referred to our department for treatment of a metastatic sternal tumor in the manubrium sterni. Primary lesion was papillary carcinoma of the left lobe of the thyroid gland. Total thyroidectomy, cervical lymph node dissection, resection of manubrium sterni with concomitant resection of bilateral clavicles, 1st ribs and 2nd ribs, and chest wall reconstruction using Marlex Mesh were performed on January 29, 2001. Considering relatively good prognosis and good response to multimodality therapy, surgical resection of sternal metastatic lesion from differentiated thyroid cancer seems to be a choice of therapy as a part of multimodality approach, including surgery, radioiodine and external radiation therapy, to thyroid cancer with systemic spread.

Abstract
We report a case of a 62-year-old woman with primary leiomyosarcoma of the chest wall which was successfully resected under the video-assisted thoracoscopic approach. The disease was found during the treatment for a malignant melanoma of the left heel. On the preoperative CT images, the lesion was suspected to be a metastasis of the malignant melanoma. The thoracoscopic surgery revealed that the tumor originated from the parietal pleura, and it was resected with a 5-mm margin of normal pleura. Histopathologically, the tumor was diagnosed as low-grade leiomyosarcoma. Since no residual tumor cells were proven in the resected margins histologically, further resection was not performed. At present, she is alive and well with no sign of recurrence of leiomyosarcoma two years and one month after operation. Thoracoscopic surgery is worth trying for accurate diagnosis of and effective treatment for a chest lesion without apparent invasion of the chest wall on the preoperative CT images.

Abstract
We studied the bioavailability of magnesium (Mg) in spinach after boiling with distilled water, using Mg-deficient growing male rats. The rats were fed a semipurified diet (Mg:0.063 per cent (w/w)) for 3 days. then a Mg-deficient diet (Mg:0.001 per cent (w/w)) for 5 days. They were then divided randomly into 7 groups of 6 rats each, and fed the semipurified diet (Mg: 0.063, 0.045 or 0.027 per cent (w/w)), or the spinach-supplemented diet (10 per cent (w/w) dried and powdered spinach after boiling with distilled water for 3 min at 100 degrees C). The Mg content of the diets supplemented with spinach grown on chemical nutrients, and on manure from pigs, cattle and fowl, was 0.069, 0.051, 0.043 and 0.036 per cent (w/w), respectively. Water intake and volumes of urine and faeces were significantly greater in the rats fed the spinach-supplemented diets than in those fed the semipurified diets. Apparent absorption of Mg, and urinary and faecal excretions of Mg were directly related to Mg intake: no significant difference was observed amongst the groups. Both the ratios of Mg absorption and retention were significantly lower in the rats fed diets supplemented with spinach than in those fed semipurified diets. The plasma Mg level was directly related to Mg intake in the rats fed the semipurified diets and the spinach-supplemented diets. However, the plasma Mg level in the rats fed spinach grown organically on manure from fowl tended to be higher than in the other groups. From these results, it was concluded that bound Mg in spinach was effectively utilized by Mg-deficient rats, however, the absorption and retention rates of Mg in rats fed diets supplemented with spinach were decreased. Possible explanations were discussed.

Abstract
OBJECTIVE To assess the reliability, validity, and sensitivity of outcome measures that might be used in a clinical trial of surgery for the treatment of severe tremor associated with MS (MS tremor). METHODS Nine patients with MS tremor were evaluated before and 3 and 12 months after thalamic surgery (six thalamotomy, three deep brain stimulation). A clinical tremor rating scale (CTRS), a novel quantitative movement analysis technique (QMA), and a variety of measures of disability, neurologic impairment, and quality of life was utilized. RESULTS Both the CTRS and QMA were reliable measures of tremor and both were sensitive to the improvement in tremor following surgery. However, QMA correlated with disability measures and corresponded better to patient and examiner assessment of surgical results. The disability scales used were insensitive to functional improvements that may follow surgery. The box and blocks test clearly separated three patients who had excellent results from three who had poor results. Baseline QMA values predicted improvement on the box and blocks test. CONCLUSIONS 1) QMA is a reliable, objective and valid measure of MS tremor that could be used in a clinical trial. 2) The box and blocks test can detect the improvement in prehensile function that follows surgery, but standard disability scales are poorly responsive to this change. 3) Preoperative QMA values may predict which patients are most amenable to functional improvement after surgery.

Abstract
Thymidine phosphorylase (dThdPase) is identical to platelet-derived endothelial cell growth factor (PD-ECGF), and has angiogenic activity. It has been reported that a higher level of dThdPase activity is associated with an unfavorable patient prognosis. The activity of dThdPase was investigated in 15 patients who underwent hepatectomy for hepatic metastasis from colorectal carcinoma, and an assessment was made as to whether its expression was correlated with the prognosis. The dThdPase activity was significantly higher in the patients with extrahepatic metastasis after hepatectomy (n = 5) than in those without extrahepatic metastasis (n = 10) (168.2 +/- 50.8 vs 95.1 +/- 35.2 Unit/mg prot., p < 0.05). This dThdPase activity could be a significant prognostic indicator, and was useful in predicting the extrahepatic recurrence after hepatectomy for hepatic metastasis from colorectal carcinoma.

Abstract
We examined influences of increased soluble Fas (sFas) and hyaluronan in uremia on apoptosis and peripheral blood mononuclear cell (MNC) adhesiveness. Synovocytes, human umbilical cord endothelial cells (HUVEC), human coronary artery smooth muscle cells (CASMC), and MNC were prepared in this study. In cultures of synovocytes, HUVEC, and CASMC, sFas or high molecular hyaluronan was added to media at medium change. After 1 day, Fas-positive cells were calculated by fluorescence-activated cell sorting. Uremic level of sFas enhanced Fas-positive cells in all cell lines (P < 0.01) not in CASMC. On the contrary, hyaluronan inhibited Fas expression in all cell lines (P < 0.05). In culture with uremic serum, Fas were induced in all cell lines. At this time, the hyaluronan levels of the supernatant were measured and hyaluronan production was estimated. In contrast to the results using sFas supplement, hyaluronan production was increased in culture with sFas and uremic sera. MNC adhesiveness was increased in synovocytes and HUVEC lines by adding hyaluronan or sFas. Higher adherent cell numbers were recognized when both sFas and hyaluronan were added to the media. A most remarkable increase in cell numbers was observed in uremic MNC suspension as compared with that of MNC from healthy subjects. In conclusion, these results indicate that increased sFas in uremia stimulates apoptosis and hyaluronan production. Both sFas and hyaluronan are responsible for accelerated MNC adhesiveness in uremia.

Abstract
We have isolated two Ca2+-dependent, galactose-binding polypeptides from the budding tunicate, Polyandrocarpa misakiensis. Based on their partial amino acid sequences, full-length cDNAs were cloned. One of them was identical with a tunicate C-type lectin (TC14-2) reported previously. The other was a novel C-type lectin, referred to as TC14-3. In living animals, they appeared to be coupled. This complex of lectins, when applied in vitro to tunicate multipotent cells of epithelial origin, blocked cell proliferation and induced cell aggregation. The aggregates expressed a homolog of the integrin α-chain and other differentiation markers specific for epithelial cells. Recombinant TC14-3 could reproduce all the activities of native lectins by itself, which was accelerated by recombinant TC14-2. The inhibitory activity of TC14-3 on cell growth was completely abolished by the addition of 50 μM D-galactose. Anti-TC14-3 monoclonal antibody showed that the antigen was expressed constitutively by the multipotent epithelial and mesenchymal cells. These results provide evidence that in P. misakiensis a C-type lectin plays a novel, cytostatic role in regulating cell growth, cell adhesion and cell differentiation during asexual reproduction.

Abstract
Among the intrahepatic cystic diseases except Caroli's disease, only biliary cystadenoma/cystadenocarcinoma may communicate with the bile duct. We present a case of biliary cystadenocarcinoma in which drip infusion cholangiographic-computed tomography demonstrated communication between an intrahepatic cyst and the biliary system preoperatively. Drip infusion cholangiographic-computed tomography, a simple and noninvasive examination, is useful for differentiating biliary cystadenoma/cystadenocarcinoma from other intrahepatic cystic lesions.
