5. Samples of this material

(ca 4.5 mg) were further subjected to hydrophobic interaction HPLC on a HiTrap Butyl HP column (1.6 × 2.5 cm, from GE Healthcare, Uppsala, Sweden) equilibrated with 100 mM PB containing 1 M (NH4)2SO4, pH 7.5. After sample application, the column was eluted with a segmented gradient of 1.0–0 M (NH4)2SO4 in the same buffer at 1 mL/min flow rate. The fractions were collected manually; the selected cytolytic fractions were combined. The buffer of the active samples was exchanged to PBS using an Amicon® Ultra device (cut-off 10 kDa) at 4 °C. As for the last step, this material (ca 700 μg) had its NaCl concentration adjusted to 0.1 M and was loaded on a Synchropak ABT 199 http://www.selleckchem.com/products/MDV3100.html SAX 300 (Eprogen, USA) anion exchange HPLC column (250 × 4.6 mm), previously equilibrated with 20 mM PB, 0.1 M NaCl pH 7.5 and eluted with a segmented gradient of the equilibrium buffer added by 1 M NaCl at 0.5 mL/min flow rate. The fractions were collected manually and the purified hemolytic fraction, referred to as Sp-CTx, was concentrated using Amicon Ultra device (as mentioned above), stabilized with glycerol (10%

v/v) and stored at −196 °C until required. The degree of purity of the hemolytic samples was assessed by SDS-PAGE according to Laemmli (1970). Hemolytic activity was assayed on rabbit erythrocytes, which are highly sensitive to fish venoms (Kreger, 1991 and Shiomi et al., 1989). Rabbit blood was collected

by cardiac puncture and mixed with Alsever’s solution (1:1 ratio). To detect the hemolytic activity during the purification procedure, samples of crude venom and purified fractions were incubated with washed erythrocytes suspension (2% v/v) in phosphate buffered saline (PBS) for 10 min at 25 °C and were centrifuged (14,000 g for 1 min) at room temperature. The amount of hemoglobin released in the supernatant was measured spectrophotometrically at a wave length of 540 nm. Total hemolysis was determined by incubating the erythrocytes suspension in distilled water. An osmotic protection assay was carried out to investigate if the formation of pores by Sp-CTx in the cell membrane is involved in the hemolytic effect of this toxin. Washed rabbit erythrocytes Carnitine palmitoyltransferase II were obtained as described above. For this experiment, saccharose and polyethylene glycol (PEG) of different molecular sizes (1000, 1450, 3350 and 8000 with SEr – Stokes–Einstein hydrodynamic radius of 1.0; 1.2, 1.9 and 3.2 nm, respectively) (Kuga, 1981) was added to hemolytic assay buffer at the final concentration of 30 mM and the percentages of hemolysis inhibition were calculated. The incubation period of rabbit erythrocytes with Sp-CTx (50 ng/mL, 2× EC50) was up to 120 min. The time course of erythrocyte lysis induced by Sp-CTx was followed spectrophotometrically at 700 nm at room temperature. The initial A700 was approximately 0.9.

7). B cells can differentiate into antibody-secreting cells upon encounter with a given antigen or pathogen. In most cases, direct activation of B cells by an antigen is observed in response to repetitive antigenic structures, such as carbohydrates found in bacterial walls. These T cell-independent responses are characterised by the secretion of low-affinity antibodies of the IgM type. This Fluorouracil datasheet type of response is often stereotyped

in nature, lacking the typical memory response upon re-exposure to the same antigen (see section titled Immunological memory). In most cases, optimal B-cell activation and differentiation into antibody-secreting plasma cells is only observed when both B and T cells are simultaneously activated by the same pathogen. In these instances, CD4+ T cells differentiate into Tfh cells that are able

to provide a helper signal to B cells. T cell-dependent B cell responses are characterised by the secretion of high-affinity antibodies and a large spectrum of isotypes (in particular IgG), and are typically associated with immunity resulting from natural exposure. Cytokines are small proteins secreted by activated innate and adaptive immune cells (such as DCs, macrophages and T cells), which direct the activity of other cells to coordinate an appropriate immune response. Cytokines find protocol MycoClean Mycoplasma Removal Kit are a diverse family of molecules which include interleukins, interferons and growth factor

responses (Appendices, Supplementary Table 5). Cytokines may act in an autocrine, paracrine or endocrine fashion, by binding cell-surface receptors and stimulating signalling pathways, ultimately affecting the gene expression of the target cell. Cytokines are referred to as either proinflammatory or anti-inflammatory, depending on their role during the establishment of immune responses. These two types then act together to control and regulate different aspects of the immune response. Immune responses are prevented, down-regulated or terminated by multiple mechanisms. These mechanisms include clonal deletion, the activity of suppressor monocytes and anti-inflammatory cytokines, induction of apoptosis, induction of unresponsiveness by resting APCs, expression of inhibitory cell-surface co-receptors and the activity of regulatory CD4+ T cells. Regulatory T cells (Treg cells) belong to the CD4+ T-cell subset. Their role is to inhibit immune or inflammatory responses by blocking the activity of effector T cells, helper T cells and APCs.

Examination of bilirubin, INR and creatinine

values were used in the MELD calculation (Model for End-stage Liver Disease).16 The Na/Ku ratio is calculated on the values of sodium and potassium in “spot” urine sample. Urine was collected within less than or equal to 48 h from admission. Collection of 24-h urine sample for calculation of sodium was done in sterile plastic containers by recording the volume in 24 h; starting at 8:00 a.m. Instructions were given to assure completeness of collection. All samples GSK1120212 were processed on the day of collection. In order to obtain the whole 24-h urinary sodium, sodium concentration was multiplied by the volume in litters. Random urine samples were obtained before or after completion of 24-h collection for measurement of ‘spot’ Na/K ratio. Any kidney disease was excluded by medical history, urinalysis, serum creatinine and ultrasound

examination of the kidneys. Numerical variables were expressed as mean and standard deviation, whereas categorical variables were described Nivolumab mouse in absolute numbers and proportions. Continuous variables were compared using either Student’s t test or Mann–Whitney when appropriate, categorical variables were analysed using either Chi-squared test or Fisher’s exact test. A P-value < 0.050 was considered statistically significant. The correlation between the Nau24h and Na/Ku ratio was evaluated by the Spearman's correlation coefficient. Diagnostic accuracy of the Na/Ku ratio was analysed by estimating the area under the receiver operating characteristics curve (AUROC) and by calculating sensitivity, specificity, positive and negative predictive value. All tests were performed by the statistics software SPSS, version 17.0 (SPSS, Chicago, IL, USA). Between August 2010 and January 2012, 42 patients admitted in the gastroenterology ward were evaluated for inclusion as they present liver Phenylethanolamine N-methyltransferase cirrhosis decompensated in ascites. Twenty-two patients without urinary sodium dosage were excluded. Twenty patients with decompensated liver cirrhosis and ascites were included. Among them, 60% presented poor urinary sodium excretion (Nau24h dosage lower than 78 mequiv.).

Among the 20 included individuals, the mean age, standard deviation and median were 56.1 ± 11.8 (54.5) years, 70.0% were men, 66.7% were Caucasian. Regard to the aetiology of cirrhosis: 33.3% had alcohol abuse and hepatitis C virus, 27.8% had alcohol only (Table 1). Three patients had hepatocellular carcinoma. When individuals with poor urinary sodium excretion were compared to those with Nau24h ≥ 78 mequiv. (Table 1 and Table 2), they exhibited a higher proportion of male sex (91.7% vs. 37.5%; P = 0.018); higher mean MELD scores (16.3 ± 9.3 vs. 5.0 ± 3.5; P = 0.002), higher mean creatinine (1.1 ± 0.4 mg/dL vs. 0.8 ± 0.2 mg/dL; P = 0.029), higher AST means (3.1 ± 1.7 vs. xULN 1.6 ± 0.7; P = 0.027), higher median bilirubin (1.1 g/dL vs. 0.3 g/dL; P = 0.013) and lower median spot urine sodium (21.5 mequiv.

The thermal dehydration of aluminum trihydroxide (gibbsite) can lead to the formation of χ, κ, ρ, η or θ transition aluminas, depending on the heating rate, the dwell temperature and the atmosphere in contact with the solid phase [1], [2] and [3]. The thermal dehydration of boehmite can afford γ, η, δ, or θ phases, depending on the conditions of dehydration, the particle size and degree of crystallinity of the starting boehmite. Pseudoboehmite, a poorly Cobimetinib order ordered

form of boehmite with a small primary particle size, is often a preferred precursor to transition aluminas, because it typically affords derivatives with relatively high surface areas and pore volumes. Particularly, γ alumina (γ-Al2O3) is formed from well ordered boehmite at a temperature over 500 °C, depending on the particle size. Pseudoboehmite can be transformed

to η alumina upon dehydration [1], [2] and [3]. Carboxylate-alumoxanes are prepared from the reaction of boehmite [Al(O)(OH)]n with carboxylic Pifithrin-�� ic50 acid (HO2CR). Although, they are given the general formula, [Al(O)x(OH)y(O2CR)z]n where 2x + y + z = 3 and R = C1–C14 [1], carboxylate-alumoxanes are in fact alumina nanoparticles between 5 and 200 nm in diameter. The surface of the nanoparticle is covered with covalently bound carboxylate groups [4] and [5]. Some of the simple carboxylic acids which have been used are: acetic acid, methoxyacetic acid, methoxy (ethoxy) acetic acid, methoxy (ethoxy ethoxy) acetic acid, hexanoic acid etc. Some of the carboxylic acids containing other functionalized groups are: 4-hydroxybenzoic acid, 4-aminobenzoic acid, methacrylic acid, hydroxylacetic acid, aminoacetic acid, 6-aminohexanoic acid, lactic acid, l-lysine etc [4]. Carboxylate-alumoxanes have found applications in a variety of interesting fields, such as the following: synthesis of metal doped aluminum oxides, catalyst components, preparation of ceramic membranes, synthesis of hollow alumina spheres, strengthening of porous alumina ceramics, and fabrication of fiber reinforced ceramic matrix composites, fabrication of biocompatible nanocomposites, polymeric see more nanocomposites, performance improvements

of lithium batteries, non-skid and non-flammable coatings and MRI contrast agents [6] and [7]. In this sense, we have developed a method for the control of the porosity and pore size distribution on the synthesis of γ-alumina: reacting boehmite with a mixture of carboxylic acids from the extract of rosin, to produce carboxylate-alumoxane nanoparticles; drying the carboxylate-alumoxane nanoparticles; and firing the dried nanoparticles at a temperature of 650 °C. The rosin, main components of the colophony extract, is a mixture of isomeric cyclic carboxylic acids with the general formula C19H29COOH and it is produced by heating fresh liquid oleoresin to vaporize the volatile liquid terpene components [8] and [9].

Proteins were detected using Universal His Western Blot Kit 2.0 (Clontech) according to the manufactures protocol. For mass spectrometric protein identification TDH-bands were excised from Coomassie blue stained SDS gels, destained with 50% acetonitrile: 50 mM ammonium bicarbonate and the gel was dehydrated by the addition of enough 100% acetonitrile

to cover each gel piece. Finally, the samples were dried in a Speed-Vac for 5 min. The sample was rehydrated with 10 mM DTT, incubated for 45 min at 56 °C and then alkylated with 54 mM iodoacetamide: 25 mM ammonium bicarbonate for 30 min at room temperature in the dark. Samples were washed two times in 10 mM ammonium bicarbonate followed by incubation in 10 mM ammonium bicarbonate:

50% acetonitrile. After the final dehydration the sample was dried in a Speed-Vac. this website The gel bands were rehydrated (with a 12.5 ng/ml solution of trypsin) in ice cold 50 mM ammonium bicarbonate and incubated on ice for 30 min. Gel www.selleckchem.com/products/AZD8055.html bands were covered by adding 50 mM ammonium bicarbonate, then placed at 37 °C overnight. The trypsin digestion was stopped by the addition of 1% trifluoroacetic acid: 30% acetonitrile. Samples were centrifuged and the supernatants concentrated using ZipTip C18 pipette tips according to the manufacturers instructions (Millipore, Billerica, MA). Peptide extracts were mixed on the MALDI-TOF sample plate with matrix and dried. The matrix was a concentrated solution of α-cyano-4-hydroxy-cinnamic acid in 1% trifluoroacetic acid: 50% acetonitrile (Bruker Daltonics, Bremen). MALDI TOF-MS was performed using a Bruker Ultraflex II MALDI-TOF mass spectrometer (Bruker Daltonics, Bremen). MALDI-MS/MS mass spectra were acquired in LIFT mode. Database searches (NCBI), through Mascot were performed via BioTools 3.0 software (Bruker Daltonics) using PMF and MS/MS (PFF) datasets. Rucaparib A reversed passive latex agglutination test (KAP-RPLA test) was used for the detection

of cell-free produced TDH proteins (Denka Seiken, Tokyo, Japan). The KAP-RPLA “Seiken” specifically detects V. parahaemolyticus TDH with rabbit antisera. The test was performed according to the manufacturer’s instructions. Briefly, 5 μl of CRMs from each in vitro transcription-translation reaction were added to 95 μl of diluent reagent and serial twofold dilutions were made with 25 μl diluent reagent in microtiter plates. Each suspension was tested in parallel with sensitized latex and control latex (25 μl each, five dilutions per series). The plates were incubated overnight at room temperature. In order to investigate the hemolytic activity of cell-free synthesized TDH proteins, 10 μl aliquots of in vitro translation reaction (CRM and SN) were directly spotted on a blood agar plate. Toxin concentrations in supernatants were adjusted to a concentration of 120 μg/ml with the SN of the no template control (NTC) reaction.

“For high-resolution applications, the majority of cardiovascular magnetic resonance studies are performed with respiratory gating during free-breathing using diaphragmatic navigators [1] and [2]. The accept/reject algorithm [3] and [4], used to limit respiratory motion to a small (typically 5 mm) gating BMS-354825 clinical trial window around end expiration, is inherently inefficient and unpredictable particularly in the presence of respiratory drift [5]. A number of Afatinib datasheet techniques including motion adaptive gating [6] and phase encode ordering methods [7], [8] and [9] reduce the effects of respiratory motion within the navigator acceptance window, enabling improved image quality or greater respiratory efficiency. Alternatively, navigator information may be used to both gate and provide input to respiratory motion models which relate the motion of the diaphragm to that of the heart. The most basic of these models uses a fixed superior–inferior

factor to perform slice tracking [1] and [10], but tracking factors vary considerably between subjects [11] and [12], and calculating accurate subject-specific values is both difficult and time consuming. More complex models, Glutamate dehydrogenase often derived from multiple navigators,

include three-dimensional (3D) translational [13] and affine transformations [14], [15] and [16] which take into account the nonrigid deformation of the heart and its hysteretic relationship with the diaphragm. Such methods have enabled increases in the acceptance window from 5 to 10 mm without loss of image quality, resulting in improved respiratory efficiency (from ∼40% [4] to ∼70% [17]). These models, however, are derived from a prescan and do not adapt to changes that may occur over subsequent long acquisitions. Several novel non-model-based alternatives have been developed which derive respiratory motion information directly from the anatomy of interest. Self-gated techniques use respiratory information obtained from a repeated superior–inferior projection within the acquisition to gate [18] or perform one-dimensional translational corrections [19], while other methods reconstruct heavily aliased subimages from a subset of the full high-resolution acquisition on every cardiac cycle for respiratory gating [20] or to obtain 3D affine corrections [21]. Alternatively, simultaneously acquired additional low-resolution images have been used to obtain two-dimensional (2D) in-plane translational corrections [22] and rotations [23].

Non-Hispanic black males and females had higher percentages repor

Non-Hispanic black males and females had higher percentages reporting less than a high school education than did non-Hispanic whites and males and females of other races/ethnicities. Significantly more non-Hispanic black males and females, Hispanic males and females, and males of other races/ethnicities lived in households making less than $25 000 and at less than 131% of the poverty threshold compared with their non-Hispanic http://www.selleckchem.com/products/SGI-1776.html white counterparts. Mean intakes of DF were far below recommendations for all Americans with all children and adolescents aged 2 to 19 years and adults aged 20+

years consuming 13.7 and 17.1 g DF/d, respectively (Table 2). Males consumed significantly more DF on the day of the survey, on average, than did

females. Nevertheless, adult males aged 20+ years consumed less than 19 g DF/d, which is about half of the AI (30-38 g DF/d) recommended by the IOM. Adult females consumed less than 16 g DF/d, on average; AI for adult females is 21 to 25 g DF/d [1]. In general, non-Hispanic blacks had the lowest mean intake of DF. However, mean DF intake was below AI across all races/ethnicities. Hispanic children and adults consumed significantly more DF than did non-Hispanic blacks; however, there was no difference in average DF intake between non-Hispanic whites and non-Hispanic black children and adolescents Anti-diabetic Compound Library cell assay on the day of the survey. While Hispanic males aged 2 to 19 years consumed more DF than non-Hispanic black males, there was no difference in mean intake of DF among female children and adolescents across race/ethnicity. Race/ethnicity played a role in average DF intake among adults as well (Table 2). Overall, non-Hispanic white MycoClean Mycoplasma Removal Kit adults consumed significantly more DF than did non-Hispanic black adults. Non-Hispanic black males had significantly lower DF intake on the day of the survey compared with non-Hispanic white,

Hispanic, and males of other races/ethnicities. Females of other races/ethnicities, on average, consumed the most DF among all females. Moreover, Hispanic and non-Hispanic white females consumed significantly more DF than did non-Hispanic black females. Annual family income does not appear to influence DF intake among children and adolescents (Table 3); however, this study supported the hypothesis that lower family income negatively affects DF intake among adults (Fig. 2). On average, adults with annual family income more than $75 000 consumed about 18 g DF/d—significantly more than adults in lower-income categories. Among adult males, those with the lowest annual income (<$25 000) had significantly lower DF intake than did males with higher incomes (Table 3). Females with the highest income ($75 000+) consumed significantly more DF, on average, than did females in the 2 lower-income categories.

More than 80% of KPC mice, but only 30% of FKPC mice, developed abdominal distension due to hemorrhagic ascites ( Figure 6C). On average, KPC mice harbored 1.57 mL ascitic fluid, and FKPC mice showed almost none ( Figure 6C). Metastasis was dramatically reduced in FKPC mice ( Figure 6B and Supplementary Table 4). Around 95% of KPC mice and only 55% of FKPC mice had local metastasis to intestinal mesentery ( Figure 6B, D, and E). Forty-four percent of KPC mice, but only 13% of FKPC mice, developed diaphragm metastasis ( Figure 6B). Similar to local metastasis, 52% of KPC mice and only 13% of FKPC mice showed

distant liver metastasis ( Figure 6B click here and F). Both mesenteric and liver metastases of KPC mice were positive for fascin and p53 ( Figure 6D and F). KPC mice had shorter survival overall than FKPC with liver metastases ( Figure 6E). We conclude that loss of fascin significantly reduces ascites and metastasis to mesentery, diaphragm, and liver. To further investigate the mechanism by which fascin promotes metastasis, we first

examined the actin dynamics of PDAC cells (105768) from the FKPC mice compared with the same cell line rescued with GFP-fascin. GFP-fascin concentrated in filopodia (Figure 7A and FDA approved Drug Library Video 1). Fascin rescue cells showed dynamic filopodia assembly and turnover ( Supplementary Figure 8A and B). Filopodia were significantly less frequent, shorter, and shorter-lived in fascin-deficient cells than fascin-rescued cells ( Supplementary Figure 8B). Lamellipodial dynamics were greater in fascin-rescued cells ( Supplementary Figure 8C and Video 2). Expression of fascin significantly enhanced protrusion frequency, distance protruded, and protrusion rate, and decreased protrusion persistence ( Supplementary Figure 8C). Fascin-rescued PDAC cells migrated faster PJ34 HCl than fascin-deficient cells ( Supplementary Figure 8D and Video 3). Fascin-expression status did not affect growth in 2D or 3D ( Supplementary Figure 8E), similar to PDAC in vivo. In addition, fascin-rescued cells behaved similarly to fascin-deficient cells during anoikis ( Supplementary Figure 8E). Fascin expression increases PDAC cell migration

via lamellipodial and filopodial dynamics, but does not affect growth and survival. Formation of mesenteric and diaphragm metastases involves transmigration of cancer cells through the mesothelial cell (MC) layer.27 and 28 We tested a potential role for fascin in mesothelial transmigration by plating PDAC cells (105768) on top of a monolayer of human Met5a MCs. PDAC cells opened MC junctions and intercalated themselves between MCs (Supplementary Figure 9A). GFP-fascin localized intensively to the filopodia at the leading edge of transmigrating PDAC cells ( Figure 7A and Video 4). About 75% of fascin-rescued PDAC cells, but only 35% of fascin-deficient cells, intercalated by 10 hours ( Figure 7B, Supplementary Figure 9B, and Video 5).

The objective of this study was to evaluate the oxidative stability of the PS-enriched chocolate bars during 5 months of storage, see more and its main effects on color, texture, sensory quality and potential bioactivity of the functional food product. As the oxidation of sterols reaction can start with the hydroperoxides formation (Lengyel et al., 2012), the primary oxidation of unsaturated lipids was measured

by the hydroperoxide concentration (Fig. 1). When stored at 20 °C (Fig. 1A), the hydroperoxide peak (1.39 mmol/kg) occurred after 60 days of storage. Thereafter, the hydroperoxide decomposition rate was greater than its formation. At 30 °C (Fig. 1B), the maximum value (1.06 mmol/kg) was reached after 30 days, thus being earlier but lower than the peak observed at 20 °C. Hamid and Damit (2004) evaluated cocoa butter stability during storage at 15 and 70 °C and observed that the increase of temperature anticipated the peroxide peak from 6 to 4

months, even though the maximum values were similar in both storage conditions. The peroxide value observed in the chocolate samples during the shelf-life study was lower than 3.0 milli equivalent O2/kg (or 1.5 mmol/kg). This value can be considered low when compared with PV of other fresh vegetable oils, such as coconut (4.9 milli equivalent CYC202 nmr O2/kg), soybean (2.4 milli equivalent O2/kg) or canola (5.0 milli equivalent O2/kg) (Chaiyasit, Elias, McClements, & Decker, 2007). This low hydroperoxide content observed in chocolates was consequence of

the high proportion of saturated (50 g/100 g) and monounsaturated (40 g/100 g) fatty acids present in the cocoa butter. Only less than 10 g/100 g of the fatty acids observed in our samples were polyunsaturated, being the proportion of the most susceptible fatty acid (α-linolenic acid) lower than 1 g/100 g. Major fatty acids levels observed in the treatments during storage at 30 °C suggested that no significant alterations were detected during the shelf-life. Fatty acids proportion observed in the CONT samples after 150 days at 30 °C were: 27.94 ± 0.06, 18.79 ± 0.51, Ribose-5-phosphate isomerase 41.104 ± 0.06, 7.82 ± 0.29 and 0.26 ± 0.01 g/100 g; for C16:0, C18:0, C18:1, C18:2 n6 and C18:3 n3 respectively; while the mean values obtained to PHYT and PHAN samples were: 22.19 ± 0.12, 24.64 ± 0.21, 40.91 ± 0.15, 7.58 ± 0.10 and 0.90 ± 0.03 g/100 g for C16:0, C18:0, C18:1, C18: 2 n6 and C18:3 n3 respectively. In both storage conditions (20 and 30 °C) it was observed a trend of the PS-enriched bars to oxidize more than the bars formulated with palm oil (Fig. 1). In our chocolate bars, it was expected that C18:3 n3 had been the major responsible for the hydroperoxide formation, since no differences were observed for C18:2 n6 levels between the samples. In fact, the chocolates bars formulated with phytosterols (PHYT and PHAN) presented 236% more C18:3 n3 than those formulated with palm oil (CONT).

53%) of the combination group and in four patients (23.53%) of the chemotherapy group. No significant difference was found between the two groups (23.53% Selleck Epacadostat vs 23.53%; P > 0.05). No serious adverse events were observed ( Table 3). The results of our study suggest that CT-PFNECII combined with second-line chemotherapy produced a higher response rate and improved survival than second-line chemotherapy in platinum-pretreated stage IV NSCLC. In addition, side effects of this combination

therapy were generally well tolerated. Compared with ORR of 11.76% and DCR of 35.29% in the chemotherapy group, the combination therapy provided an ORR of 23.53% and a DCR of 58.82% in platinum-pretreated stage IV NSCLC. Of note, one complete tumor regression was achieved in a patient by two cycles of combination treatment. More importantly, all patients who had lung tumor–related chest pain or dyspnea before our treatment achieved significant symptom relief even within 72 hours after CT-PFNECII treatment. Our pilot

study suggests that CT-PFNECII combined with second-line Ceritinib manufacturer chemotherapy has potent antitumor activity against platinum-pretreated NSCLC tumors. The benefit of our combination treatment in terms of survival outcomes was also quite encouraging. Considering that 29.41% of patients in our study population were platinum resistant (five patients in each arm) and 58.82% of the patients (10 of 17) received CT-PFNECII two times, the PFS of 5.4 months and OS of 9.5 months by our combination treatment were more valuable. The side effects of CT-PFNECII such as transient mild pain and cough in patients with lung cancer were minimal and well tolerated because only quite small amount of cisplatin and quite low concentration of ethanol were injected intratumorally. In addition, mild pneumothorax 2-hydroxyphytanoyl-CoA lyase and mild hemoptysis relating to the procedure were uncommon because we used a 22-gauge fine needle under the precise guidance of CT. Furthermore, combination of CT-PFNECII with second-line chemotherapy did not worsen common side effects of chemotherapy. No significant differences in chemotherapy-related adverse events in the two groups

were noted, indicating clinical safety of CT-PFNECII. We previously found that 5% ethanol could potently inhibit ABCG2 pump, which is a major drug transporter in protecting platinum-resistant NSCLC cells from cytotoxic agents. We also found that 5% ethanol-cisplatin injected intratumorally could eradicate cisplatin-resistant lung tumors by killing chemoresistant lung CSCs and normal lung cancer cells [10]. We speculate that the residual unkilled but damaged tumor cells in the 5% ethanol-cisplatin treatment group might be more fragile and sensitive to second-line chemotherapy agents. As a result, we speculate that CT-PFNECII treatment might have synergistic effects with systemic second-line chemotherapies, such as docetaxel or pemetrexed, in controlling platinum-pretreated NSCLC.
