Transduction with the OKT3::CD14 construct resulted in Bw5147 cells expressing high levels of membrane-bound anti-CD3 antibody fragment on their surface and were thus termed Bw-anti-CD3high stimulator cells. Single cell clones were obtained from both Bw lines and cell clones expressing homogenous amounts of membrane-bound anti-CD3 antibodies were selected for further use. cDNAs encoding human CD80, CD58, CD54, CD150, EPZ015666 manufacturer TL1A, 41BB-L and ICOS-L were PCR amplified from a human dendritic cell library and cloned into the retroviral expression vector pCJK2 generated in our laboratory. Integrity of these expression plasmids was confirmed by

DNA sequencing. Using retroviral transduction these molecules were expressed on the T cell stimulator cells as described (Steinberger et al., 2004). Control stimulator cell lines expressing no human molecule were generated by treating T cell stimulator cells with supernatants derived from retroviral producer cell lines transfected

with empty vector DNA or a vector encoding GFP. All T cell proliferation assays were done in triplicates, means and SD are shown. For T cell proliferation assays human T cells (1 × 105/well) were co-cultured with irradiated (6000 rad) T cell stimulator cells (2 × 104/well) for 72 h. In some experiments Adalimumab Sirolimus manufacturer (Humira, Abbott Laboratories, Chicago, IL) or Beriglobin P as control (CSL Behring GmbH, Marburg, Germany), was added at a final concentration of 10 μg/ml at the onset of culture. To assess T cell proliferation methyl-3[H]-thymidine (final concentration: 0.025 mCi; Perkin Elmer/New England Nuclear Corporation, Wellesley, MA) was added for the last 18 h prior harvesting of the cells. Methyl-3[H]-thymidine uptake was measured as described (Pfistershammer et al., 2004). Purified human T cells (5 × 105/well) were co-cultured in 1 ml medium with 1.2 × 105 irradiated anti-CD3high T cell stimulator cells expressing human

costimulatory molecules as indicated. Following 7 days of culture, T cells were harvested, counted and analyzed for CD8+ expression. 5 × 105 T cells were re-cultured with 1.2 × 105 irradiated stimulator cells as described above. Five rounds of stimulation were performed. For each round of stimulation the T cell expansion factor was calculated by dividing the starting cell Liothyronine Sodium number by the cell number obtained after 7 days of stimulation. Cytotoxic activity of expanded T cells was measured using a europium release assay kit (Delfia, Perkin Elmer) following the manufacturer’s protocol. Briefly, expanded T cells (1 × 105/well) were incubated with the labeled target cells (5 × 103/well; Bw-anti-CD3high cells or Bw cells not expressing anti-CD3 as control) for 2 h at 37 °C. For detection of cell lysis-associated europium release 20 μl of supernatant was transferred to a 96-well flat bottom plate and 200 μl enhancement solution was added.

, 2007a and Barichello et al., 2007b). Oxidative stress is associated with a range of changes in cell function, including membrane lipid peroxidation CP-868596 cell line as well as alterations in gene and protein expression, and signaling pathways (Gunduz-Bruce, 2009). These events can be caused by abnormally intense exposure to glutamate, which

can be neurotoxic primarily through overactivation of the N-methyl-d-aspartate subtype of glutamate receptors and are associated with what we found when the animals were subjected to sepsis, in different brain regions 12 and 24 h after surgery. On the other hand, recently it has been demonstrated that GUA can act as a neuroprotective agent in an experimental model of oxidative stress injury ( Roos et al., 2009). The mechanism involved in GUA neuroprotection ( Schmidt et al., Selumetinib 2007) has been attributed to its ability to stimulate glutamate uptake in brain slices and in astrocytes, an essential neurochemical parameter involved in neuroprotection against excitotoxicity ( Danbolt, 2001 and Maragakis and Rothstein, 2001). It is possible that, in our study, GUA counteracted the oxidative damage in lipids and protein in brain regions by lowering the sepsis-induced increase

in glutamate 12 and 24 h after CLP. Furthermore, our results observed that carbonyl and TBARS show different patterns in the prefrontal cortex at 12 h and in the cortex at 24 h, in this context the free radicals can differently damage biomolecules and in this way is always important to determine more than one biomarker of oxidative damage, such as the TBARS and carbonyl. There are several differences in these techniques (sensitivity, source of radical that generates damage, repair of the damaged molecule) thus it is quite difficult to determine with precision the exact reason

to the observed difference. Intensive care unit survivors Methocarbamol experience neurologic impairments, and generally, memory is the most frequently observed deficit, followed by executive function and attention deficits. Some studies have been published with the intent to determine the molecular mechanisms associated with late memory deficits in the context of critical care medicine (Bermpohl et al., 2005, Irazuzta et al., 2005, Lehnardt et al., 2006 and Martins et al., 2005). Because oxidative stress is associated with the development of neurodegenerative disease (Halliwell, 2006) and is important to the development of a multiple organ dysfunction syndrome during sepsis (Salvemini and Cuzzocrea, 2002), it is reasonable to suppose that it could contribute to long-term memory deficits in sepsis survivors. We previously described that the short-term oxidative damage could participate in the development of central nervous system symptoms during sepsis development, or even septic encephalopathy (Barichello et al.

cruzi-induced depression The SSRI antidepressant FX has anti-inf

cruzi-induced depression. The SSRI antidepressant FX has anti-inflammatory activity; it decreases IFNγ, upregulates IL-10 and inhibits the activation of NF-κB (Abdel-Salam et al., 2004 and Koh et al., 2011). NF-κB is a nuclear factor crucial for TNF gene transcription Talazoparib manufacturer (Tracey et al., 2008). Hence, we tested whether the beneficial effect of FX in T. cruzi-induced depressive disorder was related to the systemic down-regulation of TNF mRNA. This was not the case, however, as similar TNF mRNA levels were detected in saline- and FX-treated T. cruzi-infected mice. Subsequently, the participation of

TNF in T. cruzi-induced depressive-like behavior was tested by treating chronically (120 dpi) T. cruzi-infected C57BL/6 mice with PTX, a phosphodiesterase inhibitor

that decreases TNF synthesis ( Shaw et al., 2009), or the chimeric anti-TNF neutralizing monoclonal antibody infliximab ( Tracey et al., 2008). Although TNF plays an important role in parasite control in the acute phase of infection ( Lannes-Vieira et al., 2011), no parasite burden was observed, suggesting that infection was not reactivated or reacutized by interfering with TNF in chronically T. cruzi-infected mice. Importantly, the immobility time assessed by the TST was significantly decreased after PTX and anti-TNF administration, supporting the idea that TNF may have a pivotal role in the induction of depressive-like behavior during chronic infection. Accordingly, exogenous TNF administration induces acute depressive-like behavior, supporting a role for this cytokine in behavioral alterations ( Kaster selleck chemicals et al., 2012). Despite the very low parasite load, patients develop more severe forms of Chagas disease during the chronic stage

( Dutra et al., 2009 and Rassi et al., 2010), when high TNF levels in the serum are detected ( Ferreira et al., 2003, Talvani et al., 2004 and Gomes et al., 2005). Our study highlights that T. cruzi-induced long-lasting TNF expression may contribute to depressive-like behavior in Chagas disease. Because non-infectious chronic cardiac disorders are associated RG7420 chemical structure with high TNF levels ( Shaw et al., 2009), our findings become more broadly important. Interestingly, Bz and PTX also regulate NF-κB activation ( Shaw et al., 2009 and Manarin et al., 2010). Therefore, the genesis of depressive-like behavior in Chagas disease may reside in a complex network of interactions triggered by the parasite that involve the immune stressor TNF and mechanisms that may induce increase in TRYCATs and serotonin paucity ( Fig. S4). Altogether, our findings support the existence of a chronic nervous form of Chagas disease, contribute to the understanding of pathogen-borne cytokine-driven chronic depression and open new avenues for therapeutic interventions in depressive disorders. Our results indicate that T.

g. Chamorro-Premuzic and Furnham, 2008, Duff, 2004 and Furnham, 2011). Learning motives concern why students learn; they precede learning strategies that refer to how students learn ( Biggs, 1987). Together motives and strategies inform learning approaches, which are unrelated to intelligence (e.g. Chamorro-Premuzic & Furnham, 2008) but overlap with personality traits (e.g. Duff et al., 2004 and Furnham et al., 2009). While their relationship with academic performance is multilayered ( Haggis,

2003), it is unknown to what extent learning approaches are explained by personality traits and intelligence. Typically, three learning Selleck Ku 0059436 approaches are differentiated: deep, achieving and surface learning ( Biggs, check details 1987). Deep learners seek to explore a topic to the greatest possible extent, aiming for a better understanding of the subject matter and its wider context. Achieving learners study to obtain the rewards that are attached to high academic results, such as a prestigious job offer or monetary rewards. Surface learners only learn those facts that are indispensable to pass, thereby applying minimum but highly targeted study efforts (cf. Biggs, 1987). In line with this, research studies have shown that deep and achieving learning lead to better grades while surface learning tends to precede lower marks (e.g. Chamorro-Premuzic and Furnham,

2008, Duff, 2004 and Furnham et al., 2009). However, the Miconazole empirical evidence for the association between learning approaches and academic performance is often inconsistent ( Haggis, 2003). Learning approaches overlap conceptually and empirically with broad personality traits, i.e. the Big Five that span Neuroticism, Extraversion, Openness to Experience, Agreeableness

and Conscientiousness, with shared variances ranging from 25% to 45% (e.g. Duff et al., 2004 and Zhang, 2003). A recent review showed that Neuroticism is positively related to surface learning and negatively to deep learning; Extraversion and Conscientiousness are positively associated with deep and achieving learning; and Openness is strongly linked to deep learning (Chamorro-Premuzic & Furnham, 2009). However, some data have challenged these associations, especially with regard to Extraversion (Chamorro-Premuzic & Furnham, 2009). Beyond the Big Five, deep and achieving learning have been shown to be positively correlated with Typical Intellectual Engagement (TIE), a trait that describes intellectual curiosity (Goff & Ackerman, 1992). Conversely, surface learning is negatively associated with TIE (e.g. Furnham et al., 2009). TIE refers to individual differences in typical intelligence or investment, that is, the desire to engage with and understand the world or the need to know ( Goff & Ackerman, 1992), which is conceptually very similar to deep learning.

Estes resultados sugerem que a doença afeta de forma mais negativa as mulheres celíacas do que os homens. Seria expectável que o cumprimento da DIG se associasse positivamente com a qualidade

de vida. No entanto, os resultados obtidos não o mostraram. Na extensa pesquisa realizada sobre o assunto não se encontraram outros trabalhos que tivessem abordado tal questão. Contudo, podem adiantar-se algumas explicações para esta observação: a) pode acontecer que os doentes celíacos não cumpridores da DIG sejam os que apresentam sintomatologia mais ligeira, o que não lhes compromete significativamente a qualidade de vida; b) não menosprezando que quer a sintomatologia quer o cumprimento da DIG afetam a vida dos doente celíacos, pode acontecer que os não cumpridores da DIG considerem que esta opção, mesmo acarretando sintomas indesejados, lhes Silmitasertib manufacturer perturba menos o seu dia a dia, do que o cumprimento da dieta e c) não pode ser excluída a possibilidade de o instrumento utilizado não ser suficientemente

sensível para diferenciar estes 2 grupos. O facto BKM120 dos participantes diagnosticados nos últimos 12 meses tenderem a apresentar piores pontuações foi igualmente reportado por Zarkadas et al. ao verificarem que os doentes diagnosticados no último ano apresentavam piores pontuações comparativamente àqueles diagnosticados há mais de 12 meses39. Estes resultados serão justificáveis pelas dificuldades encontradas na aprendizagem e no seguimento da DIG, bem como pelas alterações no estilo de vida por ela impostas, especialmente nos primeiros meses após o diagnóstico, que podem ser assoladoras, exigindo grande esforço e comprometimento por parte do doente40 and 41. Sabe-se, contudo, que estas dimensões também dependem de fatores culturais. Por isso teve-se a preocupação de comparar a qualidade de vida dos doentes celíacos com a da população portuguesa no geral (tabela 5). Quando se comparam as pontuações obtidas ifenprodil em todos os domínios do SF-36 dos participantes do estudo com

aquelas obtidas para a população portuguesa ativa dos 25-34 anos28, grupo etário que engloba a mediana das idades da amostra em estudo, verifica-se que, surpreendentemente, as pontuações médias dos participantes celíacos são mais elevadas em todas as dimensões, com exceção da «vitalidade», domínio relacionado com os níveis de energia e de fadiga. De facto, verificam-se diferenças estatisticamente significativas no domínio vitalidade, mas também nas dimensões «capacidade funcional», «aspetos físicos», «dor» e «aspetos emocionais». A perceção do estado de saúde e de qualidade de vida da amostra de doentes celíacos estudada parece ser melhor do que o que se verifica na população em geral.

He began his study of medicine at the University of Wilno in Eastern Poland (now part of Lithuania) under Soviet occupation where he completed the first trimester, and joined the Polish Army and spent World War II from 1940 to 1945 as a prisoner of war in Germany and France, an experience he speak sparingly of except about when he escaped from his imprisonment in Hamburg, Germany and recaptured in Strasbourg, France. He resumed his medical education at the University of Brussels, Belgium after the LEE011 purchase war and graduated with a M.D. degree in 1949. As a student, he listed

seven papers, wherein he is a co-author or author, pertaining to the effects of hormone on vaginal cytology from the Research Laboratory of the Department of Obstetrics and Cytology. He PARP inhibitor emigrated to Canada in 1951 where he was

in private practice, served a year residency in medicine at the University Hospital in Saskatoon, and joined its faculty where he obtained a research fellowship in the laboratory of Dr. E.R. Yendt in the Department of Medicine, University of Toronto to study metabolic bone disease, parathyroid, kidney stones and renal hypertension. Dr. Yendt spent time with Dr. John E. Howard at John Hopkins University, a former member of Fuller Albright’s team in Massachusetts General Hospital. George moved to the University of Ottawa in 1963 from Saskatoon where he was involved in the first hospital to introduce maintenance hemodialysis and kidney transplantation in Canada. In late 1960, George decided to spend his sabbatical years working in calcified tissue laboratories. He wrote about his sabbatical in the Medical Research Council of Canada short summary of research accomplishment and personalized biography of their most

talented senior award winner in Canada as follows: “Subsequently the work of two investigators influenced my research. First, that of Dr. Harold Frost, head of Orthopedics at Henry Ford Hospital in Detroit, originator of a method of studying lamellar bone turnover system by means of bones labeled in vivo with tetracycline. Second that of Dr. Webster S.S. Jee, Anatomy professor at the University of Utah in Salt see more Lake City in whose laboratory I familiar myself with the study of cell kinetics by means of tritiated thymidine”. Originally he was to stay 3 months in Frost’s laboratory but he extended it to 9 months where he came in contact with other “Frostians” which included Pierre Meunier, Eimei Takahashi, Bruce Epker, Bob Hattner and others. George spent a short 3 months in my laboratory in which he enhanced my research by critiquing our manuscripts and mentoring my postdoctoral trainees and summer dental student investigators.

Damages to both sides occur less frequently and includes only 5%

Damages to both sides occur less frequently and includes only 5% of all OBPP [1]. Just as with unilateral damages, it may occur due to mechanical trauma during delivery or intrauterine pathology. Injury is caused by concurrent traction, compression, fracture of the humerus and congenital torticollis [1], [2] and [3]. OBPP may be associated with paralytic dislocation of the shoulder [4]. There is an emphasis on the relationship of injuries with shoulder dystocia, fetal macrosomia or extremely high birth weight, maternal diabetes (it affects the child’s weight, proportions,

and perhaps more sensitive tissues), advanced maternal age or obesity, prolonged second stage of labor, clavicle fracture, and instrumental birth. Among intrauterine pathology factors, the SB203580 order most frequently

reported are fetal malposition (breech or transverse position), prematurity, oligohydramnios, compression of the umbilical cord wrapped around the neck of the child, uterine fibroids, muscular hypotension due to necrosis of the newborn, and CNS hypoxia [2], [3], [4] and [5]. Bilateral obstetric brachial see more plexus paralysis is a main complication in breech birth [6] and [7]. Damage may occur in the upper part of the plexus C5-C6 (Erb-Duchenne palsy), middle C7, C8-Th1, lower (Déjerine-Klumpke’s palasy) and in the whole plexus C5-Th1. A common injury is an upper – middle type C5, C6, C7. The anatomical division of injury includes preganglionical lesions, i.e. detachment of roots from the spinal cord (avulsion) and peripheral

lesions involving the roots, trunks, cords and nerves leaving the plexus. Many infants with OBBP have neuropraxia and recover spontaneously because neuropraxia tends to disappear within 4–6 weeks. Axonotmesis is a type of nerve injury requires regrowth of the axon to the target muscle, which takes a considerable amount of time (12–18 months) [4]. The consequences of injury are paresis, constrained positions, trophic disturbance and hypoplasia of the Metformin manufacturer shoulder girdle and upper limb, as well as motor and posture pattern changes [2] and [3]. One of the unfortunate sequelae in OBPP is upper limb length discrepancy [8]. The severity of OBPP determines the functional changes, the process of regeneration and appropriate treatment options. The boy was full-term from a second pregnancy born in a breech position with manual help, with a birth weight of 3200 g, asphyxia and an Apgar’s score of 1. Because of respiratory failure, immediately after delivery, he had to be treated in the Neonatal Intensive Care Unit (ICU) with artificial ventilation during seven days. He was diagnosed with encephalopathy. Increased muscle tension, periodic seizures, stiffening of the whole body, apnea and symptoms of renal impairment were observed. Neonatal Cranial Ultrasound showed minor periventricular leukomalacia (more on the right side).

Nonetheless, the ability to discriminate the distinct and redunda

Nonetheless, the ability to discriminate the distinct and redundant functions that drive cancer-related aspects of a given cancer

type remains Small Molecule Compound Library possible within an in vivo context, because PCs have different tissue and intracellular localizations. Because we believe that targeting PCs upstream of converging cancer pathways could attenuate the aggressiveness of cancer cells with limited physiological drawbacks on normal cells [3], this is of great relevance for the development of targeted therapeutic strategies. The question remains as to which PCs need to be targeted, to provide the best chances of a beneficial effect. To evaluate the relative cancer-sustaining functions of each PC in ovarian cancer, we used a gene-silencing method to generate individual cell lines, each lacking an endogenously expressed PC member. Because pharmacological compounds selectively targeting each member of the PC family are limited, this method represents the best option allowing for the direct comparison of the implication

of PCs in cell proliferation both in vitro and in vivo [12]. On the basis of the observation that ovarian tumor tissues, and also ascites cells and metastases, display variable levels of PC expression (Oncomine databases; Figure 1A), we opted for the SKOV3 cells to explore the relative implication of each PCs, as they coexpressed the four relevant PCs: furin, PACE4, PC5/6, and PC7 (see Figure 1B). Using in vitro proliferation assays, we observed the effects of PACE4 and PC7 molecular Wnt inhibitor silencing through proliferation and colony formation assays in these cells. In vivo xenograft formation assays supported the phenotype observed with PACE4-silenced cells; however, the observations in this assay contrasted with PC7 knockdown cells, which displayed unexpected increased tumor progression capabilities when implanted in athymic nude mice, contrasting

with the in vitro proliferation assays. Although we found a decreased growth rate for the shPACE4 tumors, we observed a greatly increased proliferation of shPC7 tumors. Such contradictory results between in vitro and in vivo growth conditions have been reported by Couture et al. for prostate cancer cell lines Anidulafungin (LY303366) [11], and these results highlight the importance of also validating in vitro observations in a more physiological context to take account of the conditions within the tumor microenvironment. We also examined various biomarkers in relation to PACE4 and PC7 knockdown cell–derived xenografts. A statistically significant reduction in the Ki67 proliferation index was observed in the PACE4-silenced xenograft, supporting the observed growth phenotype. This phenomenon was in agreement with our previous report resulting in similar conclusions [11].

Mice received LPS derived from Salmonella abortus equi (L5886, Si

Mice received LPS derived from Salmonella abortus equi (L5886, Sigma, Poole, UK) at a dose of 100 μg/kg, via intra-peritoneal injection,

unless stated otherwise. This dose of LPS reduces burrowing, open-field activity, changes core body temperature and gives a reproducible cytokine response in the brain ( Teeling Tacrolimus molecular weight et al., 2007). Anti-inflammatory drugs were given 30–60 min prior to LPS injection as indicated in Table 1. Burrowing was assessed as described previously (Deacon et al., 2002, Deacon et al., 2001, Deacon, 2006 and Teeling et al., 2007). Mice received appropriate pre-treatment followed by an intra-peritoneal injection of LPS or saline. Burrowing was measured between 1 and 3 h post treatment. Open-field activity in mice was assessed using a Med Associates Activity Monitor (Med Associates Inc., Vermont). The open field consisted of an aluminium base (27 × 27 cm) enclosed

on four sides with 0.7-cm thick acrylic sheet, surrounded by an opaque screen. Each mouse was placed in the middle of Bioactive Compound Library purchase the open field and observed for 3 min. Measurement was made of total distance travelled (cm) and the total number of rears in the observation period (Felton et al., 2005). The open-field activity was measured between 3.5 and 4 h after LPS or saline injection. Body temperature was measured using a rectal probe (Physitemp, Thermalerte TH5) that gave a rapid stabilization of the measured temperature. The mice were pre-adapted to measurements of rectal temperature for two days prior to the intra-peritoneal challenges to minimise stress effects. Body temperature was measured 4.5 h after LPS or saline treatment. Mice were terminally anaesthetized and transcardially perfused with heparinised saline. Brains were rapidly removed, and a thick coronal section (2 mm) taken (at approximately −2.7 to −3.7 from Bregma). The dorsal hippocampus was then punched out from this section, rapidly frozen in liquid nitrogen and kept

at −80 °C until further use. Total RNA was extracted using RNeasy mini columns (Qiagen) according to the manufacturer’s instructions. Contaminating genomic DNA was degraded during extraction by use of DNase GNAT2 I enzyme (Qiagen). RNA samples were stored at −80 °C until assay. All equipment and reagents were supplied by Applied Biosystems Ltd. (Warrington, UK) unless stated otherwise. cDNA was generated from total RNA by the use of Taqman Gold RT reagents. The housekeeping gene glyceraldehyde-3-phosphate dehydrogenase (GAPDH) was measured in each sample by use of a rodent GAPDH Taqman kit. Assays for IL-1β, IL-6, TNF-α, COX-2 mRNA were performed as previously described (Cunningham et al., 2005). Primers used for COX-1 measurement were as follows: forward: 5′-CCA GAA CCA GGG TGT CTG TGT-3′, reverse: 5′-GTA GCC CGT GCG AGT ACA ATC-3′, probe: FAM – CGC TTT GGC CTC GAC AAC TAC CAG TG – TAMRA.

Of the 12 pts with malignant appearing strictures on BAC, subsequent histology changed the final diagnosis to benign in 3. The diagnosis of all 20 pts with benign appearing lesions Neratinib ic50 at BAC was confirmed on histology and follow up (median 56 (0-702) d). Indeterminate masses were successfully characterised in 7 patients; 4 benign and 3 malignant from appearance and histology. Intraductal extension of ampullary adenomas was confirmed in 4 of 8 pts. Therapeutic interventions included removal of stones, holmium laser lithotripsy and APC

of ampullary adenomas. Biopsies were attempted in 38 pts and were unsuccessful in 4 pts and tissue was inadequate for histopathology in a another 4 cases. From 74 procedures, one major complication occurred; a self-limiting cardiac arrhythmia, possibly from air embolism. There was no embolism with CO2 insufflation. Other complications included cholangitis (4) and pancreatitis (1). In a largely non-Asian cohort with smaller bile ducts: 1) BAC can be performed with high technical success and acceptable complication rates; 2) BAC and biopsy are particularly VE 821 useful in differentiating benign from malignant indeterminate biliary strictures

“This is an overview on safety, complications, and success rate of direct retrograde cholangioscopy (DRC) by use of an Ultra-slim Endoscope. A retrospective analysis of all patients who underwent DRC in three tertiary endoscopic centers was designed to identify safety and

success of DRC. Ultra-slim endoscopes (FujiFilm EG 530NP; Olympus GIF XP180; GIF N180) were used by the transnasal or peroral route. Entering the papilla was defined as partial success if the intended lesion could not be reached by the endoscope (complete success). In all patients, endoscopic sphincterotomy had previously been performed. An anchoring balloon catheter was used to facilitate DRC. DRC was performed Exoribonuclease in 103 cases (97 patients) with use of CO2 insufflation (95%). Partial technical success was 90% (93/103), complete success was 85% (88/103). Biopsies were taken in 50% of patients (51/103). Interventions are depicted in table 1. Complications occurred in 7 cases (7%), including fever (n=1), bleeding (n=1), bradyarrhythmia (n=1), air embolism (n=1), hypoxia (n=1) and minor perforation of an intrahepatic bile duct (n=2, Fig. 1), all were managed conservatively. In one case, perforation of the extrahepatic bile duct at the site of an incarcerated stone was surgically treated. There was no mortality associated to DRC. DRC is feasible at a high rate of intended interventions (90%) and with a low complication rate (7%).
