A headache attack developed on 10 of the 12 occasions, but no difference was found between wine types. Platelet PST type P was significantly decreased when compared to PST type M, after 2 hours on all occasions (Table 1). Valpolicella

wines are generally composed of 3 red-wine grape varieties grown in the Veneto region, of the Italy’s northeast. Corvina, Rondinella, and Molinara grapes are the trio primarily constituting the blend, but Valpolicella DOC (Denominazione di Origine Controllata) also allows for up to 15% of other red-wine varieties grown in the province of Verona, including Rossignola, Negrara Trentina, Barbera, and Sangiovese.[36] The Corvina plays the starring role in Valpolicella (up to 75%) and is regarded as the blend’s central element. It is known more for its acidity and sour-cherry flavors than for its depth. The Rondinella grape, used primarily to add color and body to the blend (up Venetoclax in vitro to 35%), offers some herbal notes and further accentuates the gentle spiciness of Corvina. Additional tannins and fresh acid are provided by the grape Molinara, though it is the least regarded of the three main grapes, and its use is on the decline. The Chianti wine type refers AT9283 order to any wine produced in the Chianti region of

central Tuscany. It is composed of 70% Sangiovese, 15% Canaiolo, and up to 20% Cabernet Sauvignon, Merlot, or Shiraz.[37] Theoretically, 上海皓元医药股份有限公司 sangiovese wines have more tannins than Valpolicella wines, but in truth its content is similar especially if the Chianti is not purely made with a variety called sangiovese grosso. High acidity and light weight, thus the need to blend with other grapes to give it a bit more structure, defines Chianti wines. In general wines are lower in tannins, especially if the grapes are picked before becoming fully ripe (which can be mid-October in Tuscany). Sour cherry, plum, and even blackberry notes, if fully ripe, are possible. Otherwise, notes of spice and mocha or vanilla are prevalent if aged in oak.[38] Perhaps, the study by Peatfield and colleagues did not show any difference

between patients because the tannin content of both wines was, in truth, similar.[10] The authors of this review article have compared the potential for triggering migraine attacks among different red wine types.[39] The wines studied were from South America and belonged to the varietal types: Cabernet Sauvignon, Merlot, Malbec, and Tannat, which have at least 75% of the nominal grapes. The 40 patients (28 women and 12 men, ages 32-53 years) had a diagnosis of migraine according to the ICHD-II criteria,[40] were regular patients of a tertiary center (the Headache Center of Rio) under various preventive treatments, considered themselves wine drinkers, and had self-identified a relationship between wine intake and migraine attacks.

T2-weighted STN contrast did not show appreciable changes with age for both the groups (Spearman correlation ≈ −.1). STN, a common stimulation target, shows an age dependent trend for normalized FSTIR MRI contrast. Although larger patient pools are needed, our work points to tissue relaxation-based changes in STN that may provide insight in early stages of brain pathology involving DBS targets in medically refractory Parkinson’s disease. “
“We performed a longitudinal analysis based on magnetic resonance (MR) imaging to investigate the brain structural and perfusion changes caused by insulin therapy in patients with type II diabetes. High resolution Selleck Neratinib three-dimensional T1-weighted fast spoiled gradient

recalled echo images and flow-sensitive alternating inversion recovery (FAIR) images were obtained from 11 patients

with type II diabetes before and 1 year after initiation of insulin therapy and 11 normal controls. Brain volume changes were investigated by a longitudinal voxel-based morphometry (VBM), and perfusion changes were evaluated by FAIR imaging between baseline and follow-up data. Significant regional gray matter (GM) expansion located in bilateral frontal, parietal, and left occipital lobes, and regional white matter (WM) expansion was shown in left precentral subcortical WM and right angular subcortical Crizotinib mouse WM after insulin therapy (P < .05 with FDR correction). Brain hyperperfusion was detected in bilateral frontal cortex, left occipital cortex, and right temporal cortex after insulin therapy (P < .05). In patients with type II diabetes, brain expansion and hyperperfusion were demonstrated 1 year after initiation of insulin therapy, and insulin therapy could contribute to the brain volume gainment in the patients with type II diabetes.

“We assess the feasibility of using the newly designed suboccipital probe fixation device (SPFD) as a convenient and reliable tool for simultaneous measurement of vasomotor reactivity (VMR) in the middle cerebral artery (MCA) 上海皓元医药股份有限公司 and basilar artery (BA). We analyzed 30 healthy volunteers’ VMR values by using both SPFD and conventional handheld method. The VMR values were measured as percentage increase of the mean flow velocity on transcranial Doppler (TCD) in response to hypercapnia induced by the rebreathing method. The VMR tests were performed three times: (1) for both MCAs, (2) for the index MCA (the better signal window) and the BA by using the SPFD, and (3) for the index MCA and the BA by using the handheld technique. The VMR values of the right and left MCAs were similar (P > .05). Although the VMR values of the index MCA and the BA obtained by SPFD application and the handheld technique were similar (P > .05), the correlation coefficient of VMR values obtained by using the SPFD was higher (r= .827, P < .001 vs. r= .568, P= .001).

5mg/day (n=78) or tenofovir 245 mg/d (n=62) or lamivu-dine 1 00mg/d +adefovir 1 0mg/d (n=50) for at least 2 years (median duration 5 years) and based on VR response after 1 year on therapy were divided into 2 groups: complete respon-ders (CR) (n=130) and partial responders

(PR) (n=40). Patients achieving initial CR with viral breakthrough up to levels<100IU/ml (blips) were investigated separately (n=30). Methods: HBV DNA [log10IU/ml], haematological and biochemical markers of liver synthetic function and HCC surveillance abdominal ultrasound including size of spleen [cm] were analysed at baseline and every 6 months during therapy and MELD & UKELD scores were calculated. 32 patients had GSI-IX supplier selleck inhibitor varices present at baseline. Results: Baseline median MELD & UKELD scores were 14 and 45 and were higher in PR than CR (14 vs 12,p=0.04; 45 vs 43,p=0.04). PLT counts and size of spleen were similar between PR and CR (145 vs 159,p=0.3 & 1 1.7 vs 10.9,p=0.2). Baseline HBV DNA was higher in

PR than CR (7.33 vs 5.27,p<0.01). Yearly virological response had 77%, 84% 90%, 96% and 98% patients; 35% patients achieved HBeAg seroconversion and 5% had HBsAg loss after 5 years NA therapy. MELD & UKELD scores improved during therapy in all patients, year 5 median MELD and UKELD scores were 12 (12 vs. 13) and 42 (42 vs 43), but PLT counts improved only in CR (year 5: 194 MCE vs. 154,p=0.03). 18 (9%) patients developed HCC and 14 (7%) had decompensation while on therapy. HCC occurred equally in CR and PR or blips patients, but decompensation was present only in patients with PR or blips. Conclusions: Long-term antiviral therapy with NA in CHB patients with cirrhosis improved liver synthetic function in all patients. Viral response prevented decompensation and disease progression. HCC prevalence (2%patients/year) was similar viral responders and partial responders.

Harrison, Abid Suddle Background & Aims. Approximately 25% of chronic hepatitis B (CHB) patients benefit from peginterferon (PEG-IFN) treatment. Polymorphisms of HLA-DP on chromosome 6 are associated with spontaneous viral clearance in Asian hepatitis B patients. Our aim was to investigate the association of HLA-DP polymorphisms with response to PEG-IFN in Caucasian CHB patients. Methods. We studied 262 Caucasian CHB patients treated with PEG-IFN alfa for one year in two randomized controlled trials (HBV 99-01 and PARC study).

At this time, the Azathioprine was ceased due to nausea and poor oral intake. Approximately 8 weeks after the first admission and while still immunosupressed for presumptive treatment for Crohn’s Disease, the patient presented Selisistat concentration with night sweats, marked weight loss, lethargy and hypoxia. Sputum and blood cultures collected at this time grew

Mycobacterium Tuberculosis. Quantiferon gold was indeterminate and HIV testing was negative. All immunosupression was ceased and directly observed therapy commenced for miliary tuberculosis infection with the presumptive diagnosis for the necrotizing granuloma in the ascending colon thought to be gastrointestinal tuberculosis. K LIEW, G RADFORD-SMITH Gastroenterology Department, Royal

Brisbane and Women’s Hospital, Brisbane, Australia see more Background: Human leukocyte antigen B27 (HLA B27) is involved in antigen presentation to T cells. It has been associated with rheumatological manifestations of inflammatory bowel disease (IBD). Recognized limitations of studies investigating HLA associations include statistical power, and the majority of HLA association studies in IBD have involved fewer than 100 cases. The prevalence of HLA B27 has also been noted to vary between studies, and its prevalence in different ethnic groups differs. Objective: Our aims are to establish the prevalence of HLA B27 in a large, consecutive series of patients with Crohn’s disease at a major secondary and tertiary center in Australia, and to compare the natural history of inflammatory bowel disease in patients with HLA B27 and those without. Of interest are whether there are differences in location and severity of Crohn’s disease, and

whether differences in extraintestinal manifestations exist. This will identify if HLA B27 is a useful prognostic marker and assist in planning treatment for patients with Crohn’s disease. Method: We retrospectively reviewed medical data of 476 hospital patients with Crohn’s disease who had been referred for HLA B27 typing between September 1999 and August 2013 from the IBD service at the Royal Brisbane Hospital. Data were reviewed from the Prime IBD Database, including gender, age at diagnosis, location, disease behaviour and the presence of extraintestinal 上海皓元 manifestations. Patient charts were reviewed for further clinical information if they were available. Results: The database included 476 patients with a HLA B7 result. 19 (4%) were HLA B27 positive. In this cohort, 62% of participants were female, consistent with published reports of greater prevalence of Crohn’s disease in adult females. The median age at diagnosis is 26 for HLA B27 positive patients and 28 for HLA B27 negative patients. Differences in location and behaviour of Crohn’s disease did not reach statistical significance. In HLA B27 positive patients isolated ileal disease occurred in 37% of cases where results were available, as compared to 48% in HLA B27 negative patients (p = 0.2461).

1C,D). Notably, although the miR-122 level in Huh7 cells was also significantly down-regulated, it was still detected on northern blot analysis (Fig. 1C,D). As shown in ICG-001 datasheet Fig. 1E, qRT-PCR data revealed that the expression levels of C/EBPα, HNF1α, HNF3β, and HNF4α gradually increased with time from e12.5 to birth, after which they either continued to increase at a much slower rate or declined slightly. Additionally, the up-regulation of HNF4α and C/EBPα (70-fold and 40-fold, respectively) was more significant than that of HNF1α and HNF3β (<10-fold). As shown in Fig. 1F, the expression of these four LETFs

was also significantly down-regulated in HCC cell lines compared with that in the adult mouse liver. Similarly, their expression levels in Huh7 cells tended to be much higher than the levels in the other cell lines. Overall, it was evident that the expression of miR-122 was strongly correlated with the expression of HNF1α, HNF3β, HNF4α, Alpelisib in vitro and C/EBPα, especially the latter two. The data suggest that these LETFs potentially regulate the expression of miR-122. To investigate whether C/EBPα, HNF1α, HNF3β, and HNF4α are involved in the transcriptional regulation of miR-122, we analyzed the promoter region of miR-122. Previous study has shown that miR-122 is derived from the 3′ end of a 4.7-kb noncoding

RNA (hcr) in the woodchuck.11 Comparison of genomic sequences across species revealed that the 5′ end of the woodchuck hcr gene22 located in a highly conserved region (≈160 bp), which was included in the predicted promoter (predicted by the FirstEF program, available at the UCSC Genome Browser [http://genome.ucsc.edu/]) of human primary

miR-122 (Supporting Fig. 2). Rapid amplification of complementary DNA ends assay revealed that the transcription start sites of human and mouse primary miR-122 locate at the same region as that 上海皓元 of the woodchuck (Supporting Fig. 3), also supporting the prediction. By scanning the predicted human miR-122 promoter with TransFac (BIOBASE gene-regulation.com, Wolfenbuettel, Germany) and Genomatix (Genomatix, Munich, Germany) software, several potential LETF binding sites were identified (Fig. 2A and Table 1). We first checked if these LETFs could act on the predicted promoter using luciferase reporter assays. As shown in Fig. 2B, the miR-122 promoter activated the expression of the downstream reporter up to 20-fold, indicating that the predicted miR-122 promoter was a true promoter. Moreover, compared with red fluorescence protein, HNF1α, HNF3β, and HNF4α further elevated expression of the reporter through this promoter (Fig. 2B). These data suggest that these three HNFs might directly bind to the miR-122 promoter. C/EBPα may bind to elements outside of the promoter, including intronic regions.19 Therefore, we further analyzed the noncoding region between the promoter and the miR-122 precursor (+38 to +4811) (Fig. 2A).

After creating a combinatorial library of approximately 1000 bis-aryl urea analogs, these compounds were screened against Raf1 to find an analog with an IC50 of only 1.1 μM. Sorafenib was discovered after several substitutions and modifications of functional groups. Not only could sorafenib inhibit Raf1, but it could also inhibit the wild-type BRaf, the oncogenic b-raf V600E kinases, VEGFR-1, -2 and -3, PDGFR-β, fibroblast growth factor receptor 1, c-Kit, Flt-3 and RET.[12, 13] SORAFENIB WORKS BY inhibiting several kinases in the MAPK pathway (Fig. 1a). The G-protein Ras

is a key member of the MAPK pathway, and it helps regulate the Raf/Mek/Erk cascade.[12] Downstream from Ras is a family of Raf serine/threonine kinases. These kinases start Roxadustat nmr a phosphorylation cascade

that eventually leads to the transcription of genes that promote cell proliferation.[14] The Raf family is made up of ARaf, BRaf and Raf1. Sorafenib targets Raf1[15, 16] and BRaf.[12] Liu et al. showed that 3–10 μm of sorafenib inhibited Mek and Erk phosphorylation in PLC/PRF/5 HCC cells, and only 1–3 μm was needed for this same effect in HepG2 HCC cells.[17] Erk phosphorylation PF-02341066 cell line is also inhibited by sorafenib in MDA-MB-231 human breast carcinoma cells, Mia PaCa 2 human pancreatic tumor cells, and HCT 116 and HT-29 human colon tumor cell lines, but not the NCI-H460 and A549 non-small cell lung cancer cells.[12] Erk activates Myc, a transcription factor for cyclin D1, which may help promote cell proliferation. Sorafenib at 10 μm medchemexpress decreases the cyclin D1 level by inhibiting Mek/Erk in both HepG2 and PLC/PRF/5 cell lines.[17] Reduced cyclin D1 levels lead to decreased transcription of genes that are involved in cell proliferation. Sorafenib induces apoptosis in multiple

cancer cell lines by downregulating and inhibiting the translation of Mcl-1, a Bcl-2 family member (Fig. 1a).[17] The pro-survivor factor Mcl-1 normally works to prevent apoptosis. It does this by inhibiting Bak, a protein that promotes apoptosis. Studies completed by Rahmani et al. demonstrated a linkage between the translational factor elF4E and Mcl-1.[18] When 1 and 10 μm of sorafenib were introduced to the HepG2 and PLC/PRF/5 cell lines, they each reduced the amount of phosphorylated elF4E.[17] At 10 μm and 16 h later, Mcl-1 protein levels were also reduced.[17] The levels of elF4E phosphorylation and Mcl-1 were both unaffected by the Mek inhibitor U0126 in HepG2 cells, showing that these downregulations are independent of the Mek/Erk signaling pathway.[17] Thus, the working model suggests that sorafenib prevents elF4E phosphorylation, blocking the initiation of Mcl-1 translation. Sorafenib also caused DNA fragmentation with a half maximal effective concentration (EC50) of 7.7 μm in PLC/PRF/5 cells and an EC50 of 2.4 μm in HepG2 cells.[17] Sorafenib can also inhibit cancer tumor growth by targeting PDGFR-β, VEGFR-2 and VEGFR-3, three tyrosine kinases that promote angiogenesis (Fig. 1b).

6), suggesting that miR-7 may have a relatively smaller effect on regulating the

expression of molecules associated with invasion. In contrast, migratory capacity was significantly down-regulated in QGY-miR-7 cells (120 ± 3 per field for five fields; P < 0.01) versus QGY-null (180 ± 8 per field for five fields) or QGY-miR-NC cells (170 ± 6 per field for five fields) (Fig. 3). Similar results were observed in both invasion and migration assays when cells were transiently transfected with PIK3CD siRNA#3 (Supporting Fig. S7). These results indicate that Small molecule library cell assay miR-7 participates in the regulation of cell proliferation and migration by directly regulating PIK3CD expression. We further evaluated the effects of p110δ-expression inhibition by miR-7 in the PI3K/Akt-signaling pathway. We found that the transcription of AKT, mTOR, and P70S6K, which are major components of the PI3K/Akt pathway, was down-regulated to 0.4-, 0.25-, and 0.3-fold, respectively, in QGY-miR-7 cells (Fig.

4A). The transcription of eIF4E binding protein 1 (4EBP1), which is usually inhibited by mTOR, was up-regulated by 2.7-fold, as assessed by quantitative reverse-transcription polymerase chain reaction (qRT-PCR). Total and phosphorylated protein levels of all four molecules described above showed the same results (Fig. 4B), indicating Akt inhibitor that miR-7 may be an important regulator of this signaling pathway. These findings were also validated

by using PIK3CD siRNA#3 (Supporting Fig. 8). Based on these results and previous studies that miRNA could regulate multiple and functionally related targets in one pathway,17 we wondered whether these four genes could be regulated by miR-7. As a result, no miR-7 target sites were in the AKT or 4EBP1 3′UTR, but one was found in the mTOR 3′UTR (Fig. 5A). Using the luciferase reporter assay, we found that relative luciferase activity was reduced to 38% ± 5% (25 ± 3.5 versus 66 ± 5.3) for the reporter plasmid that contained the putative miR-7 target site, but not the corresponding mutant counterpart that was cotransfected with miR-7 (Fig. 5B). Two putative miR-7 target sites were also found in the MCE公司 P70S6K 3′UTR (Fig. 5C). These two target sites repressed luciferase activity by approximately 50%, when combined with ectopic miR-7 expression (Fig. 5D). These data indicate that miR-7 can regulate the expression of mTOR, p70S6K, and PIK3CD by directly binding to target sites within the 3′UTR, supporting our conclusion that miR-7 can inhibit HCC cell proliferation and movement by regulating the PI3K/Akt/mTOR-signaling pathway. To further identify the function of miR-7 on the inhibition of tumor growth and metastasis in vivo, QGY-null and QGY-miR-7 cells were inoculated SC into the right and the left scapula of each mouse, respectively (n = 5).

“Centric diatoms of the genus Leptocylindrus are MK-2206 mouse common in the marine plankton worldwide. Only two species, L. danicus Cleve and L. minimus Gran, so far clearly belong to this genus, whose diversity has not been fully investigated. We investigated frustule and spore morphology as well as three nuclear- and three plastid-encoded markers of 85 Leptocylindrus

strains from the Gulf of Naples, and one from the Atlantic US. The strains grouped into five molecularly distinct species with different levels of morphological differentiation. Two species matched the description of L. danicus and produced similar spores but differed in morphometric characters and sub-central pore position, supporting the description of L. hargravesii Nanjappa and Zingone as a distinct species. Leptocylindrus danicus var. apora French III

and Hargraves, lacking a sub-central pore and not forming spores, was raised to the species level as L. aporus (French III and Selleck GS 1101 Hargraves) Nanjappa and Zingone. A fourth species with convex valves was described as L. convexus Nanjappa and Zingone. The fifth species matched the description of L. belgicus Meunier, considered as synonym of L. minimus. However, ultrastructural differences from all other Leptocylindrus supported the erection of the genus Tenuicylindrus Nanjappa and Zingone with T. belgicus (Meunier) Nanjappa and Zingone as type species. MCE公司 None of the sequences matched the L. minimus sequence in GenBank. The species analyzed showed different or partially overlapping seasonal distributions. Despite the addition of the new taxa, the ancient diatom lineage of the Leptocylindraceae

shows a relative species poorness and considerable morphological stasis. “
“The pigment composition of Phaeocystis antarctica was monitored under various conditions of light, temperature, salinity, and iron. 19′-Hexanoyloxyfucoxanthin (Hex-fuco) always constituted the major light-harvesting pigment, with remarkably stable ratios of Hex-fuco-to-chl a under the various environmental conditions. Increased pigment-to-chl a ratios at low irradiance confirmed the light-harvesting function of Fucoxanthin (Fuco), 19′-Hexanoyloxy-4-ketofucoxanthin (Hex-kfuco), 19′-butanoyloxyfucoxanthin (But-fuco), and chl c2 and c3. Increased pigment-to-chl a ratios at high irradiance, low iron concentrations, and to a lesser extent at high salinity confirmed the photoprotective function of diadinoxanthin, diatoxanthin, and ß,ß-carotene. Pigment ratios were not always according to expectations. The consistent increase in But-fuco/chl at high temperature, high salinity, and low iron suggests a role in photoprotection rather than in light harvesting. Low Hex-kfuco/chl ratios at high salinity were consistent with a role as light harvester, but the high ratios at high temperature were not, leaving the function of Hex-kfuco enigmatic.

Finally, qHBsAg and qHBeAg were measured in stored samples, so a falsely low titer might have been seen because the natural CHIR-99021 solubility dmso decay of viral proteins led to error in the titers. In conclusion, we report a

systematic analysis of 2 years of serial qHBsAg and qHBeAg data for patients treated with ETV. The baseline level of qHBsAg and the on-treatment decline of qHBeAg in HBeAg(+) patients were proved to be highly useful in predicting VR and SR, respectively, and this lends support to the clinical utility of quantitative serological markers. In addition, these inexpensive and simple assays provide insight into the dynamic nature of

the association between qHBsAg, qHBeAg, and HBV DNA in patients receiving antiviral therapy; further studies are warranted to validate and explore their potential role. “
“Aim:  Dietary habits SCH727965 are involved in the development of chronic inflammation; however, the impact of dietary profiles of hepatitis C virus carriers with persistently normal alanine transaminase levels (HCV-PNALT) remains unclear. The decision-tree algorithm is a data-mining statistical technique, which uncovers meaningful profiles of factors from a data collection. We aimed to investigate dietary profiles associated with HCV-PNALT using a decision-tree algorithm. Methods:  Twenty-seven HCV-PNALT and 41 patients with chronic hepatitis C were enrolled in this study. Dietary habit was assessed using a validated semiquantitative food frequency questionnaire. A decision-tree algorithm was created by dietary variables, and was medchemexpress evaluated by area under the receiver operating characteristic curve analysis (AUROC). Results:  In multivariate

analysis, fish to meat ratio, dairy product and cooking oils were identified as independent variables associated with HCV-PNALT. The decision-tree algorithm was created with two variables: a fish to meat ratio and cooking oils/ideal bodyweight. When subjects showed a fish to meat ratio of 1.24 or more, 68.8% of the subjects were HCV-PNALT. On the other hand, 11.5% of the subjects were HCV-PNALT when subjects showed a fish to meat ratio of less than 1.24 and cooking oil/ideal bodyweight of less than 0.23 g/kg. The difference in the proportion of HCV-PNALT between these groups are significant (odds ratio 16.87, 95% CI 3.40–83.67, P = 0.0005). Fivefold cross-validation of the decision-tree algorithm showed an AUROC of 0.6947 (95% CI 0.5656–0.8238, P = 0.0067). Conclusion:  The decision-tree algorithm disclosed that fish to meat ratio and cooking oil/ideal bodyweight were associated with HCV-PNALT.

As a result of the delayed

graft function, the patient required intensive care unit treatment for 1 week before the liver graft function improved. He was able to be discharged in good general condition on postoperative day 21. Case 3: A 58-year-old male presented with multiple colorectal liver metastases in the right hemi-liver as well as in segment II, III, and 10 months after resection of the primary rectal tumor followed by 5 cycles of chemotherapy containing Folfox and Avastin. A work-up including positron emission tomography and CT failed to identify extrahepatic metastases. A curative resection was considered, Fulvestrant chemical structure involving a right hemi-hepatectomy associated with wedge resections of the tumors located in the left hemi-liver. The estimated weight of the remnant liver after surgery was 320 g, reflecting 26% of the whole-liver volume and RLBW of 0.5% (Fig. 1). Postoperatively,

the patient developed severe encephalopathy, large amounts of ascites, hyperbilirubinemia up to 300 μmol/L (17.5 mg/dL), and persistent coagulopathy with a prothrombin time below 30%. He subsequently developed renal failure requiring replacement therapy by postoperative day 5 and pulmonary edema requiring reintubation. He died in the intensive care unit on postoperative day 13. These three cases illustrate the wide spectrum and clinical impact of SFSS, which possibly represents the most serious complication after partial OLT buy MI-503 and major hepatectomy. Preventing SFSS and understanding the underlying mechanisms may provide the most significant impact in improving outcome of many patients with liver diseases subjected to surgery or transplantation. 上海皓元 The liver has the fascinating ability to sustain its function, even after major reduction of its parenchymal mass, and regenerates to its normal size within a few days.1 However, there is a critical mass below which liver function cannot be preserved, leading to the widely used but poorly defined entity of SFSS, which is characterized by encephalopathy, coagulopathy, ascites, prolonged hyperbilirubinemia, and hypoalbuminemia, and is often

associated with renal impairment followed by pulmonary failure and ultimately death. A few attempts were made to standardize the definition of SFSS to enable meaningful comparisons over time and among different institutions. At this point, however, no consensus has been reached, making comparisons of studies in the literature nearly impossible. We previously attempted to define SFSS3 by the presence of two of the following three factors (bilirubin >100 μmol/L [5.85 mg/dL], international normalized ratio >2 [prothrombin time ∼33%], and the presence of encephalopathy ≥grade 3) on 3 consecutive days over the first postoperative week. SFSS should be, of course, considered only after exclusion of other causes of liver failure such as technical problems including outflow obstruction and immunological or infectious complications.
