AIM To evaluate the long-term outcome of an acute hemodynamic response-guided protocol in which acute responders to intravenous propranolol received traditional nonselective beta-blockers(NSBBs) and acute nonresponders received *** Retrospective review of a protocol for primary prophylaxis of variceal bleeding guided by the acute hemodynamic response to intravenous propranolol. Fifty-two acute responders treated with traditional NSBB(i.e. propranolol or nadolol) were compared with 24 acute nonresponders receiving carvedilol. A second hemodynamic study was performed in 27 and 13 patients, respectively. The primary endpoint was development of first or further decompensation. Secondary endpoints included death from any cause, association between acute and chronic hemodynamic response, and baseline clinical and laboratory variables related to the acute hemodynamic *** Acute responders and acute nonresponders presented similar 1, 2, and 3-year probabilities of first decompensation(NSBB: 0%, 13.7%, 26.1% vs carvedilol: 0%, 20%, 20%, P = 0.968) or further decompensation(21.2%, 26.1%, 40.9% vs 21.2%, 50.0%, 50.0%, P = 0.525). A previous episode of hepatic encephalopathy was the only independent predictor of decompensation [hazard ratio(95% confidence interval): 8.03(2.76-23.37)]. Mortality rates were similar in acute responders and acute nonresponders with compensated(P = 0.428) or decompensated cirrhosis(P = 0.429). No clinical, laboratory, endoscopic or hemodynamic parameter predicted the acute hemodynamic response. In patients receiving traditional NSBB, the acute and chronic changes of hepatic venous pressure gradient were correlated(r = 0.59, P = 0.001). Up to 69.2% of acute nonresponders gained chronic response with *** Early identification and treatment with carvedilol of acute nonresponders to intravenous propranolol improves the clinical outcome of this high-risk group of patients, probably due to its greater effects fo

BACKGROUND Tacrolimus trough levels(TTL)during the first weeks after liver transplantation(LT)have been related with long-term renal function and hepatocellular carcinoma ***,the significance of trough levels of tacrolimus during the early post-transplant period for the long-term outcome is under debate AIM To evaluate the effect of TTL during the first month on the long-term outcomes after *** One hundred fifty-five LT recipients treated de novo with once-daily tacrolimus were retrospectively *** with repeated LT or combined transplantation were excluded as well as those who presented renal dysfunction prior to transplantation and/or those who needed induction *** were classified into 2 groups according to their mean TTL within the first month after transplantation:≤10(n=98)and>10 ng/mL(n=57).Multivariate analyses were performed to assess risk factors for patient *** Mean levels within the first month post-transplant were 7.4±1.7 and 12.6±2.2 ng/mL in the≤10 and>10 groups,*** age was higher in the high TTL group 62.9±16.8 years vs 45.7±17.5 years(P=0.002)whilst mycophenolate-mofetil was more frequently used in the low TTL group 32.7%vs 15.8%(P=0.02).Recipient features were generally similar across *** a median follow-up of 52.8 mo(range 2.8-81.1),no significant differences were observed in:Mean estimated glomerular filtration rate(P=0.69),hepatocellular carcinoma recurrence(P=0.44),de novo tumors(P=0.77),new-onset diabetes(P=0.13),or biopsy-proven acute rejection rate(12.2%and 8.8%,respectively;P=0.50).Eighteen patients died during the follow-up and were evenly distributed across groups(P=0.83).Five-year patient survival was 90.5%and 84.9%,respectively(P=0.44),while 5-year graft survival was 88.2%and 80.8%,respectively(P=0.42).Early TTL was not an independent factor for patient mortality in multivariate *** Differences in tacrolimus levels restricted to the fi

Sex-specific pathways in early cardiac response to pressure overload in mice

Pressure overload(PO) first causes cardiac hypertrophy and then heart failure(HF), which are associated with sex differences in cardiac morphology and function. We aimed to identify genes that may cause HF-related sex differences. We used a transverse aortic constriction(TAC) mouse model leading to hypertrophy without sex differences in cardiac function after 2 weeks, but with sex differences in hypertrophy 6 and 9 weeks after TAC. Cardiac gene expression was analyzed 2 weeks after surgery. Deregulated genes were classified into functional gene ontology(GO) categories and used for pathway analysis. Classical marker genes of hypertrophy were similarly upregulated in both sexes(α-actin, ANP, BNP, CTGF). Thirty-five genes controlling mitochondrial function(PGC-1, cytochrome oxidase, carnitine palmitoyl transferase, acyl-CoA dehydrogenase, pyruvate dehydrogenase kinase) had lower expression in males compared to females after TAC. Genes encoding ribosomal proteins and genes associated with extracellular matrix remodeling exhibited relative higher expression in males(collagen 3, matrix metalloproteinase 2, TIMP2, and TGFβ2, all about twofold) after TAC. We confirmed 87% of the gene expression by real-time polymerase chain reaction. By GO classification, female-specific genes were related to mitochondria and metabolism and males to matrix and biosynthesis. Promoter studies confirmed the upregulation of PGC-1 by E2. Less downregulation of metabolic genes in female hearts and increased protein synthesis capacity and deregulation of matrix remodeling in male hearts characterize the sex-specific early response to PO. These differences could contribute to subsequent sex differences in cardiac function and HF.

Preparation of monospecific anti-PAG antibodies for cattle pregnancy detection: use of synthetic peptides to improve specificity

引用

Advances in Bioscience and Biotechnology 2011年第2期2卷 85-88页

作者： Jimena Inés ruiz álvarez Juan Manuel Teijeiro patricia Estela Marini 不详

Immunological methods involving pregnancy associ-ated glycoproteins (PAG) are used for cattle preg-nancy detection. The faults of these methods could be overcomed by using antibodies specific for each member of the PAG family. In order to differentiate between very similar proteins, preparation of anti-bodies specific for peptides is a method of choice. In this work, we summarize a series of considerations regarding peptide design and choose free access NCBI, Antigenicity Plot, EMBOSS Antigenic and Expasy tools to apply them. We design peptides spe-cific for different reported PAG members and obtain the corresponding polyclonal antibodies for five of them.

Endoscopic recommendations for colorectal cancer screening and surveillance in patients with inflammatory bowel disease:Review of general recommendations

引用

World Journal of Gastrointestinal Endoscopy 2017年第6期9卷 255-262页

作者： Jose María Huguet patricia Suárez Luis Ferrer-Barceló Lucía ruiz Ana Monzó Ana Belén Durá Javier Sempere Digestive Disease Department General University Hospital of Valencia46014 ValenciaSpain

Screening for colorectal cancer(CRC) in patients with inflammatory bowel disease(IBD) is recommended by all scientific societies. However, there are differences in the recommendations they make regarding screening and surveillance. We address a series of questions that come up in the daily clinical practice of a physician. The first two questions that are raised are:(1) Who should be offered screening for CRC? and(2) When should the first colonoscopy be performed? The next step is to decide who should undergo endoscopic surveillance and at what intervals they should be performed. Chromoendoscopy is emerging as the recommended endoscopic technique for screening and surveillance. The terminology for describing lesions detected with endoscopy is also changing. The management of visible lesions or non-visible dysplasia is also a motive for the review. We end the review by addressing the followup for endoscopically resected lesions. These questions often cannot be answered easily due to the varying degrees of evidence available; therefore, we have made some general recommendations based on those made by the various guidelines and consensuses. The first screening colonoscopy should be offered 8 years after a IBD diagnosis and we recommend that patients be stratified according to the individual risk for each for endoscopic surveillance intervals.
