Space and calculation speed limitations do not allow in-situ flow

Space and calculation speed limitations do not allow in-situ flow simulations. Therefore pre-simulated steady state flow fields are stored and provided for U0126 cell line online-users on our server. The connection of our model with the GENESIS system works via a ‘workflow’ WPS service in the toolbox. It is defined as a bash shell script which calls the necessary input

files from the IOW server and runs GITM (a Fortran executable), runs a Python script to post-process the model results and converts this output via a Perl script into a gml output for visualising the particle movement. Both, input and output are defined by the service provider in the DescribeProcess.xml. Anti-diabetic Compound Library in vitro It is imported into the toolbox when creating the WPS service. If end-users are calling the service on the portal, it is executed at our local toolbox. The graphical visualisation was done using the GeoServer on the local server by adding new layers from GIS shape files. Objective of the large-scale integrating project European

FP7-project GENESIS (GENeric European Sustainable Information Space for Environment), with its 29 partner institutes, was to provide an up-to-date technical framework that enables the development of customized regional and thematic information systems all over Europe. It provided generic services, portal components, information models, an application toolkit and the related documentation.

All elements took into account international standards (e.g. W3C, CEN, ISO, OGC, OASIS) and global harmonization initiatives (e.g. GEOSS, INSPIRE). For the Oder/Odra estuary, a bathing water quality information system has been developed within the GENESIS framework. The work was carried out in co-operation with major end-users, especially the Sanitary Inspectorate in Szczecin and local administrations. The system is linked to the general Coastal Information BCKDHA System Odra Estuary and provides information for the public, e.g. relevant geographical background data and bathing water quality data. However, the main purpose is to provide a supporting tool for authorities. It includes a) a prototype of an alerting system, based on in-situ sensor measurements, which informs the Sanitary Inspectorate about microbiological hazards; b) a bulletin software which supports communication between authorities, local municipalities and the public and c) simulation tools. A typical application case of the system would be the following: The suspended solid sensor serves as indictor for pollution and is located in the river north of the city. The city and the river up-stream are the main potential sources of pollution. If the sensor reports that the concentration threshold is exceeded, a message is sent via the information system to the Sanitary Inspectorate.

This prospective study of HDR salvage

monotherapy demonstrates that it is an effective and well-tolerated treatment paradigm for patients who develop locally recurrent prostate cancer EBRT. HDR brachytherapy should be considered in the local management of recurrent prostate cancer, even in patients who have been previously heavily treated with ultra-high-dose EBRT. “
“One of the critical elements that have led to improved outcomes for intermediate-risk prostate cancer patients is the use of dose escalation [1], [2], [3], [4], [5], [6] and [7]. A meta-analysis of the seven randomized dose-escalated trials has demonstrated a biochemical control benefit for intermediate-risk patients with increasing biologically effective doses (BEDs) (5). Viani et al. found that a near linear benefit was evident with escalation SAHA HDAC of the radiation dose, and there was no sign that the dose effect had reached a plateau with further escalation of the radiation dose; these studies included BED of up to 175 Gy. In addition, Levegrun et al. (8) have used posttreatment biopsies to represent local control and suggested a TCP50 of 70.5 Gy (BED of 155 Gy) and near linear tumor control improvements with doses approaching 85 Gy (BED

of 187 Gy). Current therapy for intermediate-risk patients with dose-escalated external beam radiation therapy (EBRT) plus androgen deprivation therapy

[9] and [10] result in 10-year actuarial biochemical Bafilomycin A1 chemical structure failure rates of 20–25% and local failure rates of 15–25% [11] and [12]. As seen in Table 1, most brachytherapy implant alone series result in 10-year actuarial biochemical failure rates of greater than 20% for intermediate-risk patients. Clearly, intermediate-risk prostate cancer is not uniformly eradicated Docetaxel supplier with BEDs of brachytherapy implant or dose-escalated EBRT alone (BED of 150–190 Gy) and warrants more aggressive therapy. Supplemental EBRT is one of the most reliable and consistent ways for safely escalating radiation dose levels in conjunction with brachytherapy to facilitate the delivery of higher BED levels within the prostate and the extraprostatic tissue. Using BED models published by Stock et al. (13) (using α/β of 2.0), 125I monotherapy implant prescription of 144 Gy has a BED of approximately 160 Gy based on the D90 coverage; however, combination therapy with 110 Gy of 125I implant and 50.4 Gy of supplementary EBRT yields a BED of approximately 230 Gy. This marked difference in BED has been shown to correlate with improved biochemical and local control. Stone et al.

For this, we plotted the cells using forward scatter area vs forw

For this, we plotted the cells using forward scatter area vs forward scatter peak linear and gated on the single-cell population (Figure 4A). The quality of the sort was confirmed by microscopic analysis. To increase organoid-forming efficiency and to avoid anoikis, we used nicotinamide and Rho kinase inhibitor for this experiment.

Sorted Selleck MS 275 cells (0.1%) formed organoids ( Figure 4B) that could be expanded at a 1:5 ratio on a biweekly basis ( Figure 4C). They expressed the gastric markers MUC5AC, PGC, SST, MUC6, TFF1, and TFF2, but not intestinal markers (MUC2, CDX1, and CDX2) as shown by PCR ( Figure 4D). The cellular composition of single-cell–derived organoids was very similar to the one of gland-derived organoids as shown by immunohistochemistry. In the presence of Wnt and nicotinamide, organoids contain PGC-positive chief cells, MUC6-positive mucous neck cells, and very rare SST-positive enteroendocrine cells (gland-type organoids). After 4 days of Wnt withdrawal, MUC5AC-positive mucous pit cells appear (pit-type organoids) ( Figure 4E). Quantifications corroborated these results ( Supplementary Figure 3). In summary, we did not observe any differences between single-cell– and gland-derived organoids in terms of longevity, expansion rate, marker gene expression, or composition Ipilimumab in vivo of cell types. Cultures shown in Figure 4E

are 7 months old, showing that the different cell lineages are maintained over time. We conclude that the single cells behaved as multipotent stem cells. Treatment of gastric cancer patients depends on the availability of tests for drug discovery and sensitivity. Currently, gastric cancer cell lines are available, but no system allows comparison of cancerous and normal cells from Carbohydrate the same patient. Having established the culture condition

for human normal organoids, we reasoned that human gastric tumors also could be expanded under the same conditions. To establish the culture, cells were isolated from the tumor using collagenase and hyaluronidase, seeded into Matrigel, and embedded in ENRWFG_A medium. In parallel, organoids were established from normal tissue (Figure 5A). Chromosomal metaphase spreads were obtained from the tumor organoids ( Figure 5B). Seven spreads were counted and showed aneuploidy with chromosome numbers between 70 and 160. Tumor cultures were reminiscent of the original tissue in terms of morphology shown by H&E staining and p53 accumulation as shown by p53 staining ( Figure 5C, upper panel). To further analyze the possible mutation of the p53 pathway in this tumor, we used nutlin-3, which inhibits the interaction between p53 and MDM2 and thereby induces cell-cycle arrest. Nutlin-3 requires functional p53 and MDM2 for its activity, thus cancer cells with mutated p53 are not affected by this compound. 20 As expected, the normal organoids were strongly inhibited in their growth by nutlin-3, as quantified by a luciferase-based assay.

1 to α-KTx12 4 from Tityus (Buthidae) genus species, known as but

1 to α-KTx12.4 from Tityus (Buthidae) genus species, known as butantoxin-like peptides, and the two α-KTx21 peptides, Vm23 and Vm24, purified from Vaejovis mexicanus smithi, belonging to the Iurida suborder scorpion. Butantoxins inhibit high-conductance Ca2+-activated and Shaker-B K+

channels [7] and [20], whereas Vm24 selectively and irreversibly blocks Kv1.3 channels of human T lymphocytes at pM concentrations, and it is much less active on KCa3.1 and hKv1.2 channels [30]. Similarly to the vast majority of scorpion KTxs, OcyKTx2 reversibly blocks Shaker B K+ channels with a Kd of 82 nM and the Shaker-related Kv1 family member Kv1.3 channel with a Kd of 18 nM. Comparative analysis of OcyKTx2 amino acid sequence against Selumetinib nmr those from databanks shows that it has a 70% identity to α-KTx6.10 (OcKTx5, UniProtKB Q6XLL5), a putative peptide identified in the transcriptome of Opistophthalmus carinatus. Indeed, in the phylogenetic tree ( Fig. 3), OcKTx5 is the most related peptide of OcyKTx2. On the other hand, OcyKTx2 presents 64% identity to Pi4 (α-KTx6.4, UniProtKB P84094), a K+ channel inhibitor purified from Pandinus imperator (Scorpionidae). Pi4 potently and reversibly

blocks Kv1.2, Shaker-B, check details and small conductance (SK) KCa channels [21], but is has no effect on Kv1.1 and Kv1.3 channels [19]. Finally, and interestingly, the lowest identity (35%) of OcyKTx2 with other members of the α-KTx6 family peptides is the one with α-KTx6.16 (OcyC12), a precursor sequence

identified in the same scorpion, O. cayaporum, whose mature sequence has not yet been identified in the venom [27]. This distance between these latter two peptides identified from the same species (O. cayaporum) was also observed in the phylogenetic analysis (see Fig. 3). Despite structural similarities, α-KTx6 peptides differ in their pharmacological profiles. In general, α-KTx6 peptides have specific activity for the Shaker related voltage gated K+-channels. However, some Enzalutamide peptides act on one Kv1 channel subtype and also block calcium dependent K+-channels. HsTx1 (α-KTx6.3) potently blocks Kv1.1 and Kv1.3 whereas it does not compete with 125I-apamin binding onto SK channels from rat brain synaptosomes [16]. Anuroctoxin (α-KTx6.12) is a high-affinity blocker of human T lymphocytes Kv1.3 channels, and does not block the Ca2+-activated IKCa1 K+ channels either [2]. HgeTx1 (α-KTx6.14) blocks Shaker-B with a Kd of 52 nM [26]. MTX (α-KTx6.2) is a potent and selective inhibitor of the intermediate (IK) conductance Ca2+-activated and of Kv1.2 K+ channels [5], [14] and [15]. Pi1 is inactive on Kv1.1 and Kv1.3 up to micromolar concentrations, but acts on Kv1.2 and Shaker-B channels with nanomollar affinity. IsTX (α-KTx6.12), a peptide isolated from Opisthacanthus madagascariensis, binds to Kv1.3 with low (μM) affinity [31]. Most of the α-KTxs have a common functional dyad (e.g.

HIF-1 can also directly upregulate expression of COX-2 during hyp

HIF-1 can also directly upregulate expression of COX-2 during hypoxia [31] and thus form a feedback loop to continually activate the COX-2 pathway. Hence, we speculate that COX-2 in this WT microenvironment may drive the inflammation and upregulate the aforementioned downstream targets. Thus, the current work represents a qualitative, quantitative, and spatial assessment of various inflammatory immune cells and inflammatory protein markers in WT. The correlation

and localization of TAMs Dasatinib mouse in the tumor stroma with expression of various inflammatory protein markers, such as COX-2, HIF-1, p-ERK1/2, iNOS, and NT, suggest a functional association of TAM infiltration with the overexpression of these markers (our double immunofluorescence data confirmed the same) and vice versa in WTs and demonstrate the existence of a highly inflammatory microenvironment in this disease. Overexpression of inflammatory markers in tumors, in particular COX-2, has provided a rationale for their targeting in prevention

and treatment of many cancers [32], [33], [34], [35] and [36], by COX-2–specific inhibitors alone [37], [38] and [39] or in combination with other inhibitors [40] and [41]. The current work suggests that such an approach may also be of utility for NVP-LDE225 WTs. Supplementary Figures. “
“Nasopharyngeal carcinoma (NPC), the most common cancer originating from nasopharynx, is a unique type of head and neck malignancy in terms of its unbalanced distribution, poor differentiation, strong propensity to metastasize to regional lymphatic and/or distant organs, and chemo-radiosensitivity. NPC is most prevalent in the Guangdong Sitaxentan Province of the southern China and universally associated with Epstein-Barr virus infection, with most classified as the undifferentiated non-keratinized carcinoma [1]. With the improvement of diagnosis techniques, irradiation and chemo-radiotherapy, while locoregional control rate has increased greatly in the past few decades, however, the incidence of distant metastasis has not decreased significantly, as high as 16% to 30% [2] and [3],

which becomes the leading cause of treatment failure nowadays. Currently, prediction of NPC survivals is mainly based on the TNM staging system. However, different outcomes are observed in NPC patients with the same clinical stage of tumors after receiving similar standard treatment, indicating a pressing need of prognostication utilizing some biomarkers and the TNM staging to guide individualized treatment. Friend leukemia virus integration 1 (FLI-1), which was first identified in erythroleukemia induced by Friend Murine Leukemia Virus (F-MuLV) [4], is a new member of the E26 transformation-specific (ETS) transcription factor family. FLI-1, which is localized within the 240 kb of the ETS-1 locus on mouse chromosome 9 and on human chromosome 11q23 [4] and [5], is activated through retroviral insertion mutagenesis in most F-MuLV-induced erythroleukemias.

3), i.e. responses consistent with those seen for ivDCs. Incubation of ivMACs with retinoids also tended to promote increased LPS-induced release of IL-8, IL-10, IL-1β and IL-1RA and reduction in the release of IL-1α, but these changes were not statistically significant ( Supplementary Fig. III). Moreover, no changes were

evident in the responses for ICAM-1, IL-18, and MMP-3. In the absence of LPS, comparable responses to those observed for ivDCs were seen in that the retinoids tested induced the release of MCP-1, eotaxin-1, IL-8 and VEGF; for eotaxin-1 and VEGF, responses appeared dose dependent (albeit non-significant) for all retinoids tested ( Fig. 4). There was little or no change in the cytokine response Galunisertib solubility dmso for ICAM-1, IL-1α, IL-1β, and IL-6. Although there was a tendency for the retinoids tested to induce the release of IL-10, IL-18 and MIP-1α

as well as inhibit the release of pro-inflammatory IFN-γ, IL-1RA, MIP-1β, MMP-3 and TNF, these changes were modest and in all cases not statistically significant ( Supplementary Fig. IV). The effects of retinoids on LPS-induced cytokine response from THP-1 Anti-diabetic Compound Library high throughput cells were generally similar to those observed for both ivDCs and ivMACs. Pre-incubation of THP-1 cells with retinoids resulted in reduced LPS-induced release of IL-6 as well as increased release of IL-8 (particularly evident for the latter at the highest retinoid concentrations tested) and MCP-1 ( Fig. 5); these responses were evident for each of the retinoids tested ( Fig. 5) and generally consistent with responses seen in ivDCs and ivMACs ( Fig. 1, Fig. 2, Fig. 3 and Fig. 4). Incubation of human Caco-2 cells with different concentrations each of Bcl-w ATRA, isotretinoin and 4-oxo-cis-RA resulted in no significant change in permeability of Caco-2 monolayers at all doses tested

(Supplementary Fig. V). FITC-labeled dextran was observed to be translocated effectively in EDTA-treated monolayers, a finding consistent with the known potent adverse effect of this compound on tight-junction integrity (Tomita et al., 1994). Retinoid treatment has recently been suggested to play a pathophysiological role in the development of chronic IBD, a contention based essentially on several case reports (Crockett et al., 2009 and Shale et al., 2009). However, key basic research data appear to contradict this in showing retinoids to be mainly associated with anti-inflammatory activity (Bai et al., 2009 and Straus and Glass, 2007) and, for example, substitution of vitamin A in a TNBS rat model of colitis was found to ameliorate colitis according to histological scores and weight curves (Bai et al., 2009 and Reifen et al., 2002). While the molecular effects of vitamin A and its retinoid derivatives are well understood based on studies in multiple in vitro settings ( Amann et al., 2011, Delacroix et al., 2010, Li et al., 2006, Norris et al.

The quaternary carbon at 184 29 ppm (C8) displays cross-peaks wit

The quaternary carbon at 184.29 ppm (C8) displays cross-peaks with H4 and H6, whereas the signal at 58.55 ppm (C9) couples with H5 and H7 as can be seen in the 13C,1H HMBC plot (Supporting Information, Fig. S4). The 1H NMR spectra of the coordinated to osmium(IV) 1H-indazole and

its 2H-tautomer differ significantly. In particular the chemical shift of H3 differs for 1 and 2 by ca. 10 ppm. In addition, the position of NH signal differs by 38.8 ppm (δ 124.7 ppm for [OsIVCl5(1H-ind)]− and 85.9 ppm for [OsIVCl5(2H-ind)]−). A significant downfield SB203580 order shift of C3 resonance in 1 by 99.04 ppm compared to that in [OsIVCl5(1H-ind)]− at 200.66 ppm is also of note. The shifts of other carbon signals are in the range from 1.55 to 17.51 ppm (in [OsIVCl5(1H-ind)]− the carbon resonances are at 75.94 (C9), 81.88 (C7), 106.16 (C5), 139.58 (C4), 163.74 (C6) and 173.67 (C8) ppm) [39]. The cyclic voltammograms (CV) of 1 and 2 in DMSO (0.2 M (n-Bu4N)[BF4]/DMSO) at a carbon disk working electrode,

recorded with a scan rate of 0.2 V/s, display a reversible one-electron reduction wave attributed to the OsIV → OsIII process with a potential value of 0.03 and 0.13 V for 1 and 2 respectively. Irreversible single electron reduction wave (Ired) attributed to the OsIII → OsII process is observed at − 1.43 ( Fig. 2) and − 1.33 V for 1 and 2, correspondingly. Epacadostat The redox waves OsIV/OsIII for 1 and 2 are characterized by a peak-to-peak separation (ΔEp) of 74 and 95 mV respectively, and an anodic peak current (ipa) that is almost equal to the cathodic peak current (ipc) in both cases, as expected for a reversible electron transfer process. The one-electron nature of the electron transfer process was verified by comparing the peak current height (ip) with that of the standard ferrocene/ferrocenium couple under the same experimental conditions.

The application of Lever’s equation  [58] (Eq.  (1)) [EL(Cl) = − 0.24 [59], SM(OsIII/OsII) = 1.01 [59], and IM(OsIII/OsII) = − 0.40 [59]] equation(1) E=SM∑EL+IMfor OsIII → OsII process has allowed the estimate Idoxuridine of the yet unknown EL ligand parameter for 2H-ind tautomer (1, EL = 0.18 V), whereas EL ligand parameter for 1H-ind tautomer in 2, according to Eq.  (1), is 0.28 V. Reported EL value for 1H-ind tautomer is 0.26 V [20]. This finding demonstrates the increase of the net electron-donor character (decrease of EL) of 2H-ind tautomer compared to 1H-ind tautomer, which results in decreased reduction potential of 1. The aqueous solubility of 1 is 1.2 mM at 298 K, compared to 1.3 mM for 2. The aqueous solution behavior of 1 and 2 with respect to hydrolysis was studied by optical spectroscopy at 294 K over 24 h (Fig. 3). Both complexes are stable in aqueous solution. Immediate hydrolysis was excluded since the peak at m/z 485 assigned to [OsIVCl5(Hind)]− was observed in the negative ion ESI mass spectrum of the aqueous solution of both 1 and 2 after 24 h. The UV–vis spectra of 1 and 2 are compared in Fig. 4.

e. oxygen consumption by the faecal

pellet itself and the increase in oxygen consumption by surrounding microbes because of the presence of the faecal pellet, which stimulated them by providing an alternative food source). Oxygen consumption rates were converted to carbon demand, assuming a respiration factor of 1 mol O2:1 mol CO2 ( Ploug et al. 2008). Faecal pellet carbon-specific degradation rates (FP-CSD) represents the carbon demand (μg d− 1) per faecal pellet carbon contents (μg FP− 1) and is expressed as percentage per day (% d− 1, Ploug et al. 2008). In order to determine the carbon contents of the faecal pellets, about 100 faecal pellets of each type (culture and in situ) were placed on 450°C ash-burned GFF filters for carbon analysis. Filters were fumed with HCl for 24 h and subsequently

analysed on a Leeman Lab CEC 440 CHN analyser (Reigstad et al. 2008). Samples (250 ml) for counting phyto- and protozooplankton (i.e. heterotrophic ciliates and dinoflagellates) were fixed with acid Lugol (2% vol. final concentration). Subsamples (12.5 to 100 ml) were counted microscopically after settling in Utermöhl sedimentation chambers for 48 h. The entire chamber or parts of it were examined under an inverted microscope at a magnification of × 200 and × 400. Samples for bacterial abundance (BA) were fixed with fresh formaldehyde to a final concentration of 2%. BA was determined by direct counts of DAPI-stained filter samples (0.2 μm pore size membrane filters) using an epifluorescence microscope ( Porter & Feig 1980). A minimum of 10 frames and GSK2118436 research buy 500 cells were counted in each sample. In order to determine the effects of faecal pellet origin and water type on FP-CSD, these factors were tested using a two-way analysis of variance (ANOVA) followed by an LSD post-hoc test in the case of significant results. Differences in FP-CSD between treatments were tested by one-way ANOVA, followed by a LSD post-hoc test. Normality and homogeneity of

variance were subjected to the Bartlett test prior to the application of parametric tests Phospholipase D1 (Fisher Snedecor tests applied through ANOVA). For all the statistical results, a probability of p < 0.05 was considered significant. Statistical analyses were performed using Statgraphics Plus (Manugistics, Inc., Rockville, MD, USA). All the investigated plankton groups (i.e. bacteria, phyto- and protozooplankton) had higher abundances at the chl a max than at 90 m ( Figure 1). Phytoplankton at the chl a max was dominated by Phaeocystis pouchetii, which was absent at 90 m depth. Diatoms were less abundant but with 7100 cells l− 1 at the chl a max were about 3.6 times more abundant than at 90 m. Heterotrophic dinoflagellates were more abundant than ciliates at both depths. The carbon demand of the microbial community, used as a blank for measuring the FP-CSD, was 42.4 ± 6.0 SD μg C l− 1 d− 1 and 5.5 ± 0.

The dynamometer was held approximately 45° away from the body wit

The dynamometer was held approximately 45° away from the body with the elbow joint fully extended. Participants were then instructed to squeeze with maximal effort for 5 s while exhaling and the maximum value of three trials was recorded. This test has shown good reliability in women aged 56–90 years (CV 4.2–4.6%) [51]. All statistical analyses were performed using SPSS (PASW Statistics v19.0). A Kolmogorov–Smirnov test was used to ensure all HR-pQCT data was normally distributed. Means and standard

deviations were used as descriptive statistics. To address our primary aim, descriptive characteristics (e.g. height, body mass, lean mass) were first compared across groups for men and women separately using analysis of variance (ANOVA), with a Tukey post-hoc test used to identify any significant group differences. Analysis of covariance was Epigenetic activity used to compare HR-pQCT outcomes across groups adjusting for body size and body composition, which included the covariates age, height, and body mass. A Bonferroni correction was used to adjust for multiple comparisons. To address our secondary aim we fit a hierarchical multivariable linear regression PD-0332991 supplier model. Predictors selected were those most likely to influence variance in bone parameters [3] and [52], and were entered into the model in the following order:

(1) age, height, and body mass, (2) grip strength (radius only) and knee extension torque (tibia only), and (3) sporting activity. Three dummy variables were created for sporting activity (alpine skiing, soccer, swimming) with the control group serving as a reference category. An Grape seed extract α-level of 0.05 was used for all analyses. Unless stated otherwise, in the next section all discussed differences

are statistically significant at the p < 0.05 level. For HR-pQCT parameters, unadjusted data is reported, while statistical significance is flagged after adjusting for age, height, and body mass. Adjustment for lean mass has the potential to mask differences in bone outcomes across groups when used in supplementation to age, height, and body mass [53], and in our cohort, lean mass correlated highly with body mass (r = 0.768 in women, r = 0.927 in men, p < 0.001). Therefore, lean mass was not selected as a covariate. Furthermore, lean mass that was excluded from the regression model is correlated with grip strength (r = 0.423 for women, r = 0.561 for men, p < 0.001) and knee extension torque (r = 0.430 for women, r = 0.649 for men, p < 0.001). Descriptive characteristics of the participants are provided in Table 1. For both men and women, age was similar across groups. Female swimmers were taller and leaner than soccer players and controls, and also tended to be heavier than soccer players and alpine skiers. All female athletes began training at a similar age (6.5 years–8.

“The management Vildagliptin of lung cancer is undergoing significant transition toward more personalized therapy that takes into account the histological features and molecular markers of the tumor in addition to clinical features such as smoking history, performance status and comorbidities. The 2012 Saudi Lung Cancer Guidelines incorporated emerging recommendations that have strong evidence and impact patient outcome. In this manuscript, we will highlight the major updates from the prior guidelines. The initial patient assessment is critical to determine and document 3 major variables, in addition to obtaining good history and perform physical examination. These variables are performance status (PS), smoking history and comorbidities. 1. Performance status: Historically, performance status is one of the most reliable prognostic factors in lung cancer. It dictated the management of the patients for many years.
