In the HPLC analysis, EA, rutin, (+) catechin and quercetin (3007.26, 490.74, 117.72 and 13.85 mg/100 g extract, respectively) were detected. Phytochemical group test of ASE indicated the presence of reducing sugars, 17-AAG steroids, terpenoids, saponins,

tannins and flavonoids. Thus, high level of EA in ASE, along with other phytochemical constituents might be responsible for the observed activity of the extract. (C) 2014 PVJ. All rights reserved”
“Inhibition of the non-receptor tyrosine kinase ITK, a component of the T-cell receptor signalling cascade, may represent a novel treatment for allergic asthma. Here we report the structure-based optimization of a series of benzothiazole amides that demonstrate sub-nanomolar inhibitory potency against ITK with good cellular activity and kinase selectivity. We also elucidate the binding mode of these inhibitors by solving the X-ray crystal structures of several inhibitor-ITK complexes. (C) 2013 Elsevier Ltd. All rights reserved.”
“Introduction: Pulmonary arterial hypertension (PAH) is a major cause of mortality in connective tissue disease (CTD). We sought to quantify survival and determine factors predictive of mortality in a cohort of patients with CTD-associated PAH (CTD-PAH) in the current era of advanced PAH therapy.\n\nMethods: Patients with right heart catheter proven CTD-PAH were recruited

from six specialised PAH treatment centres across Australia and followed prospectively. Using survival methods including Cox proportional this website hazards regression, we modelled for all-cause mortality. Independent variables included demographic, clinical and hemodynamic data.\n\nResults: Among

117 patients (104 (94.9%) with systemic sclerosis), during 2.6 +/- 1.8 (mean +/- SD) years of follow-up from PAH diagnosis, there were 32 (27.4%) deaths. One-, two-and three-year survivals were 94%, 89% and 73%, respectively. In multiple regression analysis, higher mean right atrial pressure (mRAP) at diagnosis (hazard ratio (HR) = 1.13, 95% CI: 1.04 to 1.24, P = 0.007), lower baseline six-minute walk distance (HR = 0.64, 95% CI: 0.43 to 0.97, P = 0.04), higher baseline World Health Organization functional PKC412 datasheet class (HR = 3.42, 95% CI: 1.25 to 9.36, P = 0.04) and presence of a pericardial effusion (HR = 3.39, 95% CI: 1.07 to 10.68, P = 0.04) were predictive of mortality. Warfarin (HR = 0.20, 95% CI: 0.05 to 0.78, P = 0.02) and combination PAH therapy (HR = 0.20, 95% CI: 0.05 to 0.83, P = 0.03) were protective.\n\nConclusions: In this cohort of CTD-PAH patients, three-year survival was 73%. Independent therapeutic predictors of survival included warfarin and combination PAH therapy. Our findings suggest that anticoagulation and combination PAH therapy may improve survival in CTD-PAH. This observation merits further evaluation in randomised controlled trials.

In many malignancies, it is overexpressed, and it plays a role in cancer progression

by enhancing tumor invasion and thereby metastatic potential. The purpose of this study was to evaluate the association between MMP-7 tissue expression and prognosis in colorectal cancer. From 623 patients who underwent surgery for colorectal GS-7977 chemical structure cancer, surgical specimens were collected into tissue array blocks and stained by immunohistochemistry for MMP-7. Specimens from 545 patients were suitable for analysis. In specimens from 105 patients (19.3%), MMP-7 scored as high; in 103 (18.9%), as moderate; and in 134 (24.9%), as mild. In 203 cases (37.2%), immunoreactivity was negative. A significant correlation appeared between MMP-7 immunoexpression and tumor differentiation. High MMP-7 positivity associated with poor prognosis during a 5-year follow-up. During longer follow-up, the differences in survival between groups disappeared. MMP-7 is a potential target for tumor therapy, which should be evaluated in clinical trials.”
“The Ascl3 transcription factor marks a subset of salivary gland duct cells present in the three

major salivary glands of the mouse. In vivo, these cells generate both duct and secretory acinar cell descendants. Here, we have analyzed whether Ascl3-expressing cells retain Bucladesine Others inhibitor this multipotent lineage potential in adult glands. Cells isolated from mouse salivary glands were cultured in vitro as non-adherent spheres. Lineage tracing of the Ascl3-expressing cells within the spheres demonstrates that Ascl3+ cells isolated from adult glands

remain multipotent, generating both duct and acinar cell types in vitro. Furthermore, we demonstrate that the progenitor cells characterized by Keratin 5 expression are an independent population from Ascl3+ progenitor cells. We conclude that the Ascl3+ cells are intermediate lineage-restricted progenitor cells of the adult salivary glands. (C) 2012 Elsevier B.V. All rights reserved.”
“Objective: To compare the efficacy of two a1-adrenoceptor antagonists, a1D-adrenoceptor-selective naftopidil (Naf) 75 mg and Selleck Anlotinib a1A-adrenoceptor-selective tamsulosin hydrochloride (Tam) 0.2 mg, for the treatment of lower urinary tract symptoms (LUTS) in men with benign prostatic hyperplasia (BPH). Methods: Seventy-seven patients with LUTS secondary to BPH were enrolled. Data were gathered from patients retrospectively: 41 patients who were prescribed Naf 75 mg for 4 weeks and 36 patients who were prescribed Tam 0.2 mg for 4 weeks, respectively. The efficacy criteria were improvement in LUTS International Prostate Symptom Score (IPSS) and quality of life (QOL) scores after dosing.

Moreover, punctured tori were reported in various Pinaceae species. Species resistant

to cavitation had thicker tracheid walls, while their lumen diameter (conduit size) was only slightly reduced, minimizing the impact on hydraulic Transmembrane Transporters inhibitor conductance. The results also demonstrated (i) the existence of an indirect trade-off between hydraulic safety and mechanical strength; and (ii) a consistency between species distribution and xylem anatomy: species with a wide torus overlap and high valve effects are found in arid environments such as the Mediterranean region.”
“Pedicle screw (PS) fixation has been widely used for spine diseases. Scientists and clinicians employ several approaches to navigate PS during operation. We have demonstrated the feasibility of monitoring the reduced scattering coefficient (mu(s)’) on the trajectory of PS using near-infrared spectroscopy (NIRS). To perform the in-vitro

monitoring, an NIRS measurement system was introduced selleckchem and the reduced scattering coefficients of different sites in porcine pedicle were accurately deduced from the spectrum. Moreover, the changes of the reduced scattering coefficient along the different paths were studied. The results show reduced scattering coefficients on different regions of bones can be significantly distinguished. Furthermore, monitoring experiments along different paths confirmed that a reduced scattering coefficient would change versus the depth of puncture in pedicles. Thus, the proposed monitoring system BIIB057 ic50 based on NIRS provides a potential for guiding PS during operation. (C) The Authors.

“Quantifying the risk of hematopoietic cell transplantation (HCT)-related mortality for pediatric patients is challenging. The HCT-specific comorbidity index (HCT-CI) has

been confirmed as a useful tool in adults, but has not yet been validated in children. We conducted a retrospective cohort study of 252 pediatric patients undergoing their first allogeneic HCT between January 2008 and May 2009. Pretransplantation comorbidities were scored prospectively using the HCT-CI. Median age at transplantation was 6 years (range, 0.1-20) and median follow-up was 343 days (range, 110-624). HCT-CI scores were distributed as follows: 0, n = 139; 1-2, n = 52; and 3+, n = 61. The 1-year cumulative incidence of nonrelapse mortality (NRM) increased (10%, 14%, and 28%, respectively; P < .01) and overall survival (OS) decreased (88%, 67%, and 62%, respectively; P < .01) with increasing HCT-CI score. Multivariate analysis showed that compared with score 0, those with scores of 1-2 and 3+ had relative risks of NRM of 1.5 (95% confidence interval, 0.5-4.3, P = .48) and 4.

However, it did not inhibit neither the uptake of D-galactose by brush border membrane vesicles nor modified the SGLT1 protein levels in Dinaciclib order the brush border, suggesting an indirect endotoxin effect. This inhibitory effect, was reduced by selective inhibitors of Ca(2+)- calmodulin (W13), protein kinase C (GF 109203X), p38 mitogen-activated protein kinase (SB 203580), c-Jun N-terminal kinase (SP 600125) and mitogen extracellular

kinase (U 0126). Conclusion: LPS inhibits the mucosal Na(+)-dependent D-galactose intestinal absorption and the Na(+), K(+)-ATPase activity when it is added to the tissue. Intracellular processes related to protein kinases seem to be implicated in the endotoxin effect. Copyright (C) 2008 S. Karger AG, Basel”
“Polyhydroxyalkanoates (PHAs) are accumulated in many prokaryotes. Several members of the Halobacteriaceae produce poly-3-hydroxybutyrate (PHB), but it is not known if this is a general property of the family. We evaluated identification methods for PHAs with 20 haloarchaeal species, three of them isolates from Permian salt. Staining with Sudan Black B, Nile Blue A, or Nile Red was applied to screen for the presence of PHAs. Transmission electron microscopy and (1)H-nuclear magnetic resonance spectroscopy were used for visualization

of PHB granules and chemical confirmation of PHAs in cell extracts, respectively. We report for the first time the production of PHAs by Halococcus sp. (Halococcus morrhuae DSM 1307(T), Anlotinib purchase Halococcus saccharolyticus DSM 5350(T), Halococcus salifodinae DSM 8989(T), Halococcus dombrowskii DSM 14522(T), Halococcus

hamelinensis JCM 12892(T), Halococcus qingdaonensis JCM 13587(T)), Halorubrum sp. (Hrr. coriense DSM 10284(T), Halorubrum chaoviator DSM 19316(T), Hrr. chaoviator strains NaxosII and AUS-1), haloalkaliphiles (Natronobacterium gregoryi NCMB 2189(T), Natronococcus occultus DSM 3396(T)) and Halobacterium noricense DSM 9758(T). No PHB was detected in Halobacterium salinarum AZD1480 NRC-1 ATCC 700922, Hbt. salinarum R1 and Haloferax volcanii DSM 3757(T). Most species synthesized PHAs when growing in synthetic as well as in complex medium. The polyesters were generally composed of PHB and poly–hydroxybutyrate-co-3-hydroxyvalerate (PHBV). Available genomic data suggest the absence of PHA synthesis in some haloarchaea and in all other Euryarchaeota and Crenarchaeota. Homologies between haloarchaeal and bacterial PHA synthesizing enzymes had indicated to some authors probable horizontal gene transfer, which, considering the data obtained in this study, may have occurred already before Permian times.”

The efficiency of incorporation is influenced by the energy input

The efficiency of incorporation is influenced by the energy input during homogenization (e.g. number of homogenization cycles) but also by the production temperature. It was found that the nanoemulsions should be produced at elevated temperatures, with low homogenization pressures but higher numbers of homogenization cycles (e.g. 300 bar and 10 cycles). The results prove that the efficiency of high pressure homogenization should not only be judged by investigating the particle size and the physical stability of the emulsions alone, but also by assessing the chemical stability of the incorporated drug.

“Background: We sought to examine

correlations between clinical validators and temperaments in clinical practice.\n\nMethods: We provided the self-report

selleck kinase inhibitor TEMPS-A (50 item long) to 123 consecutive patients seen in the Mood Disorders Program of Tufts Medical Center. Temperament was assessed as cyclothymia, dysthymia, 3-MA manufacturer irritable or hyperthymia. Cut-offs were tested using (50%) and (75%) thresholds of affirmative responses, as well as highest percent for dominant temperament. We reported no dominant temperament at 75% cut-off. Multivariate regression modeling was conducted to assess confounding bias.\n\nResults: Using clinical and demographic validators, cyclothymia was the most strongly validated temperament, followed Danusertib nmr by dysthymia and hyperthymia. Irritable temperament did not appear to be valid in this sample. A 75% item endorsement cut-off appeared to identify clinically important temperaments

in slightly less than half of this sample. Those without any temperament at 75% cut-off had better prognostic features. 50% cut-off was highly nonspecific, and poorly correlated with diagnostic validators.\n\nConclusions: Affective temperaments correlate with clinical validators, most robustly for cyclothymia. 75% cut-off on the TEMPS may provide a useful categorical definition of abnormal affective temperaments in mood disorders. With that definition, slightly less than one-half of patients with mood disorders have affective temperaments. Those without abnormal affective temperaments have better prognostic features.

“Friedreich ataxia is an inherited, progressive, neurodegenerative disorder that is clinically heterogeneous. It is caused by a trinucleotide (GAA) repeat expansion resulting in frataxin loss and oxidative stress. We assessed clinical features including the development of cardiomyopathy and scoliosis and disease progression including loss of ambulation and interference with activities of daily living, relative to the length of the GAA repeal, age of onset. and age of diagnosis in a retrospective cohort study of 61 genetically confirmed patients. The use of antioxidants Such as vitamins, dietary supplements, and idebenone was also examined.

190 of the 294 healthy mothers offered their newborns’ meconium samples for the metal analysis. Those 190 mothers were set as the control group. Arsenic (As), mercury (Hg),

lead (Pb), cadmium (Cd), and chromium (Cr) levels in these case-control meconium samples were measured by inductively coupled plasma mass spectrometry. The possible association between the metal levels and maternal GDM risk of studied subjects was assessed by binary logistic regression. Results: GDM prevalence of 12.21% was observed in the investigated 1359 participants. The concentrations of As, Hg, Cr and Cd in studied cases were significantly higher (p smaller than 0.05) than those of controls. After adjustments for maternal age, pre-pregnant body mass index, gravidity, parity, hepatitis B virus infection, Selleck LGX818 and newborn sex, As, Cd and Cr were found to be positively associated with GDM prevalence in dose-dependent manners. Among them, As was detected in all samples and its levels associated the maternal GDM with the adjusted odds ratios of 3.28 [95% CI 1.24, 8.71], 3.35 [95% CI 1.28, 8.75] and 5.25 [95% CI 1.99, 13.86] for the 2nd, 3rd and 4th quartiles, respectively. Conclusions: The present work implies that exposure to some of the selected metals (noticeably As) may contribute to maternal GDM risk during pregnancy.”
“Enamel matrix derivative (EMD) is widely considered useful to promote tissue regeneration during periodontal AZD8055 treatment. it

has been reported that the main constituent of EMD is amelogenin and that the BMP-like and TGF-beta-like activity of EMD promotes osteogenesis. However, it remains unclear see more whether those activities are dependent on amelogenin or another growth factor contained in EMD. We performed two-dimensional SDS-PAGE analysis of EMD, as well as Western blot analyses using anti-amelogenin, anti-BMP2/4, and anti-TGF-beta 1 antibodies, and amino acid sequencing.

Our results revealed that a large number of splicing forms of amelogenin, BMP2/4, and other unknown molecules were involved in EMD, though TGF-beta 1 was not. In addition we have evaluated intracellular signaling of ERK1/2 and Smad1/5/8, binding potential and alkaline phosphatase activity and have explored the potential regulatory relationship between amelogenin and BMP. Amelogenin bound to BMP2 as well as heparin/heparan sulfate. Thus, it was suggested that BMP2/4 carried over in EMD during processing promote binding activity and phosphorylate Smad1/5/8 in osteoblasts. On the other hand, amelogenin did not phosphorylate Smad1/5/8, but rather ERK1/2. Further, high-density amelogenin reduced the inhibition of alkaline phosphatase activity by noggin, though amelogenin did not have antagonistic properties against BMP. Together with the above findings, our findings suggest that the BMP2/4 contaminated during the purification process of EMD because of the avidity of amelogenin plays an important role in signaling pathway of calcification.

\n\nObjectives: To assess muscle strength, aerobic capacity, and walking performance compared with normative values in chronic hemiparetic stroke patients and, thereby, to investigate the potential for endurance and resistance training. Second, to study the relations between muscle strength, aerobic capacity, and walking performance using normalized test values.\n\nDesign: Population-based, cross-sectional study.\n\nSetting: University hospital, outpatient clinic.\n\nParticipants: Patients (N=48) aged 50 to 80 years with reduced muscle strength and walking capacity due to an ischemic stroke 6 to 36 months prior

BMS-777607 molecular weight to recruitment.\n\nInterventions: None.\n\nMain Outcome Measures: Peak oxygen consumption (Vo(2)peak) and isometric Lazertinib purchase knee extensor muscle strength at the paretic knee were expressed as absolute and normalized values using normative data. The six-minute walk test (6MWT) and the habitual ten-meter walk test (10MWT) were secondary parameters.\n\nResults: Peak Vo(2) was 77% (95% confidence interval [CI], 71-84) of the expected value,

and the strength of the paretic knee was 71% (95% CI, 64-78), whereas walking speed (10MWT) was 59% (95% CI, 52-66) and walking distance (6MWT) was 59% (95% CI, 52-67). The normalized Vo(2)peak correlated to the normalized 6MWT (r=.58; P<.001) and normalized 10MWT (r=.53; P<.001). Normalized strength of the paretic knee correlated to normalized 6MWT (r=.40; P<.01) and normalized 10MWT (r=.31; P<.05).\n\nConclusions:

Lower extremity muscle strength and aerobic capacity are related to walking performance, which suggests a potential for endurance and resistance training in rehabilitation of walking performance in chronic hemiparesis after stroke. Correction for the influence of age, weight, and height providing normalized values improves the interpretation of severity of impairments and enables comparisons between patients.”
“Recordings from recent earthquakes have provided evidence that ground motions in the near field of a rupturing fault differ from ordinary ground motions, as they can contain a large energy, or “directivity” pulse. This pulse can cause considerable damage during an earthquake, especially to structures Selleck BI6727 with natural periods close to those of the pulse. Failures of modern engineered structures observed within the near-fault region in recent earthquakes have revealed the vulnerability of existing RC buildings against pulse-type ground motions. This may be due to the fact that these modern structures had been designed primarily using the design spectra of available standards, which have been developed using stochastic processes with relatively long duration that characterizes more distant ground motions. Many recently designed and constructed buildings may therefore require strengthening in order to perform well when subjected to near-fault ground motions.


“A recent series of papers by Charles T Perretti and coll


“A recent series of papers by Charles T. Perretti and collaborators have shown that nonparametric forecasting methods can outperform parametric methods in noisy nonlinear systems. Such a situation can arise because of two main reasons: the instability of parametric inference procedures in chaotic systems which can lead to biased parameter estimates, and the

discrepancy between the real system dynamics and the modeled one, a problem that Perretti and collaborators call the true model myth”. Should ecologists go on using the Screening Library molecular weight demanding parametric machinery when trying to forecast the dynamics of complex ecosystems? Or should they rely on the elegant nonparametric approach that appears so promising? It will be here argued that ecological forecasting based on parametric models presents two key comparative advantages over nonparametric approaches. First, the likelihood of parametric forecasting failure can be diagnosed thanks to simple Bayesian model checking procedures. Second, when parametric forecasting is diagnosed to be reliable, forecasting uncertainty can be estimated on virtual data generated selleck with the fitted to data

parametric model. In contrast, nonparametric techniques provide forecasts with unknown reliability. This argumentation is illustrated with the simple theta-logistic model that was previously used by Perretti and collaborators to make their point. It should convince ecologists to stick to standard parametric approaches, until methods have been developed to assess the reliability of nonparametric forecasting. (C) 2015 Elsevier Ltd.

“Freshwater mussels are among animals having two different, Lonafarnib in vitro gender-specific mitochondrial genomes. We sequenced complete female mitochondrial genomes from

five individuals of Anodonta anatina, a bivalve species common in palearctic ecozone. The length of the genome was variable: 15,637-15,653 bp. This variation was almost entirely confined to the non-coding parts, which constituted approximately 5% of the genome. Nucleotide diversity was moderate, at 0.3%. Nucleotide composition was typically biased towards AT (66.0%). All genes normally seen in animal mtDNA were identified, as well as the ORF characteristic for unionid mitochondrial genomes, bringing the total number of genes present to 38. If this additional ORF does encode a protein, it must evolve under a very relaxed selection since all substitutions within this gene were non-synonymous. The gene order and structure of the genome were identical to those of all female mitochondrial genomes described in unionid bivalves except the Gonideini.”

Methods: BEAS-2B and primary normal human bronchial epithelia

\n\nMethods: BEAS-2B and primary normal human bronchial epithelial cells were stimulated

with TG beta(1) and expression of epithelial and mesenchymal markers assessed by quantitative real-time PCR, immunoblotting, immunofluorescence microscopy and zymography. In some cases the epithelial 17DMAG cells were also incubated with corticosteroids or IL-1 beta.\n\nResults were analyzed using non-parametric statistical tests. Results: Treatment of BEAS-2B or primary human bronchial epithelial cells with TGF beta(1) significantly reduced the expression level of the epithelial adherence junction protein E-cadherin. TGF beta(1) then markedly induced mesenchymal marker proteins such as collagen I, tenascin C, fibronectin and a-smooth muscle actin mRNA in a dose dependant manner. The process of mesenchymal transition was accompanied by a morphological change towards a more spindle shaped fibroblast cell type with a more motile and invasive phenotype. Corticosteroid pretreatment did not significantly alter the TGF beta(1) induced transition but IL-1 beta enhanced the transition.\n\nConclusion: Our results indicate, that TGF beta(1) can induce mesenchymal transition in the bronchial epithelial cell line and primary cells. Since asthma has been strongly associated with increased

expression of TGF beta(1) in the airway, epithelial to mesenchymal transition may contribute to the contractile and fibrotic remodeling process that accompanies chronic asthma.”
“In colorectal cancer (CRC), no biological marker is known that could serve both as a marker for detection and prognosis. this website Electron spin resonance (ESR) spectroscopy of spin-labeled fatty acid (FA) molecules Cediranib Protein Tyrosine Kinase inhibitor binding to human serum albumin is a suitable method for the detection of conformational changes and alterations of transport function of albumin through changes in its FA binding capabilities.\n\nThe aim of this study was to examine whether the FA binding to albumin is detectably and significantly

altered in CRC patients when compared with patients having benign colorectal diseases.\n\nOne hundred four patients operatively or endoscopically treated for CRC, sigmoid diverticulitis, or a colorectal adenoma were examined before procedure. Albumin was analyzed by ESR with spin-labeled FA. A determination ratio (DR) was calculated from the measured ESR spectra as ratios of the fraction of FA that is tightly bound vs. the fractions that are loosely interacting with albumin or are unbound.\n\nPatients with CRC showed significantly lower DR values (DR, -0.09 +/- 0.98 vs. 0.61 +/- 1.43) than patients with benign colorectal diseases, consistent with a change of conformation and transport function of albumin in CRC. Within the CRC group, with advanced tumor stage, the difference in DR values increased. ESR of FA binding to albumin thus seems to be suitable for detection of patients with CRC. Furthermore, a correlation with advanced tumor stage can be established.

“Epstein-Barr

virus (EBV) infection has been observed in tumor-infiltrated macrophages, but its Vactosertib molecular weight infection effects on macrophage immune functions are poorly understood. Here, we showed that some macrophages in the tumor stroma of nasopharyngeal carcinoma (NPC) tissue expressed the immunosuppressive protein indoleamine 2,3-dioxygenase (IDO) more strongly than did tumor cells. EBV infection induced mRNA, protein, and enzymatic activity of IDO in human monocyte-derived macrophages (MDMs). Infection increased the production of tumor necrosis factor alpha (TNF-alpha) and interleukin-6 (IL-6), whereas the neutralizing antibodies against TNF-alpha and IL-6 inhibited IDO induction. EBV infection check details also activated the mitogen-activated protein kinase (MAPK) p38 and NF-kappa B, and the inhibition of these two pathways with SB202190 and SN50 almost abrogated TNF-alpha and IL-6 production and inhibited IDO production. Moreover, the activation of IDO in response to EBV infection of MDMs suppressed the proliferation of T cells and impaired the cytotoxic activity of CD8(+)

T cells, whereas the inhibition of IDO activity with 1-methyl-L-tryptophan (1-MT) did not affect T cell proliferation and function. These findings indicate that EBV-induced IDO expression in MDMs is substantially mediated by IL-6- and TNF-alpha-dependent mechanisms via the p38/MAPK and NF-kappa B pathways, suggesting that a possible role of EBV-mediated IDO expression in tumor stroma of NPC may be to create a microenvironment of suppressed T cell immune responses.”
“Treatment Sapanisertib delay, or the time lapse between diagnosis and surgery, may have a detrimental effect on cancer outcomes. This study assesses the effect of treatment delay

on cancer-related outcomes in a large, continuous series of surgically treated colon cancer patients. All surgical colon cancer cases at our center from 2004 through 2011 were reviewed. Patients who underwent preoperative chemotherapy, emergency admissions, palliative cases, and incidental and postoperative diagnoses were excluded. Treatment delay was correlated with outcomes in univariate and multivariate regression and proportional hazards models. In 769 included patients, for every treatment-delay quartile increase, odds of death decreased by an odds ratio (OR) of 0.78 (p = 0.001), and metastatic recurrence by OR 0.78 (p = 0.013). Shorter survival duration had a hazard ratio (HR) of 0.81 (p = 0.001) and shorter disease-free survival HR 0.72 (p smaller than 0.001). Multivariate regression adjusting for baseline staging greatly reduces these ratios, and makes them non-significant.
