The frozen swine kidney cells stored in each cryotube were rapidly thawed at 37 °C and split into three or five T-75 flasks. After being cultured for 7–10 days, a mixed monolayer cell sheet formed, and macrophage-like cells began to actively proliferate on the cell sheet. The proliferating macrophage-like cells were loosely attached to the cell sheet, and large numbers of macrophage-like cells (1×105–1.5×106 cells/T-75 flask) were harvested from the culture supernatant by centrifugation (1500 rpm for 5 min) every 3–4 days for 1–2 months. Immunocytochemical

analyses were performed as described previously [10] and [11]. Primary antibodies against cytokeratin this website 18 (CK18; Millipore Co., Billerica, MA), cytokeratin

PF-02341066 chemical structure 19 (CK19; Progen, Heidelberg, Germany), α-smooth muscle actin (SMA; Progen), macrophage scavenger receptor MSR-A:CD204 (KT022; TransGenic, Inc., Kumamoto, Japan), Iba 1 (Wako Pure Chemical Industries, Ltd, Osaka, Japan), and CD172a (VMRD, Inc., Pullman, WA) were used. Macrophages were also isolated from a mixed primary culture of swine liver tissue, as described previously [10]. Mouse kidney macrophages were isolated from a mixed primary culture of C57BL/6 mice kidney cells according to the protocol used to isolate macrophages from the swine kidney tissue, before being immortalized by retroviral transduction of human c-myc, as described in our previous studies [12]. The clonal macrophage cell line (KM-1) was established and routinely cultured with growth medium. RT-PCR analyzes were performed as described previously [13], with minor learn more modifications. The following oligonucleotide primers were used: mouse P2X7R (NM011027): sense, 5′-GACAAACAAAGTCACCCGGAT-3′, and antisense, 5′-CGCTCACCAAAGCAAAGCTAAT-3′; swine P2X7R (XM001926804): sense, 5′-GACAAACAAAGTCACCCGGAT-3′, and antisense, 5′-CTTGTCACTCACCAAAGCAAAG-3′; swine glyceraldehyde-3-phosphate dehydrogenase (GAPDH)

(NM001206359): sense, 5′-TCACCAGGGCTGCTTTTAAC-3′, and antisense, 5′-GATCTCGCTCCTGGAAGAT-3′. The amplified DNA fragments derived from mouse P2X7R, swine P2X7R, and swine GAPDH mRNA were 101, 106, and 192 bp (bp) long, respectively. A mouse β-actin primer (#G5740, Promega, Madison, WI) was also used, and the resultant 285 bp DNA fragment was amplified. The cells were re-suspended in HEPES-buffered salt solution (HBSS; 145 mM NaCl, 2.5 mM KCl, 1 mM MgCl2, 1.8 mM CaCl2, 20 mM HEPES, 10 mM glucose, and 0.01% BSA; pH 7.4), and the [Ca2+]i was measured at 30 °C by monitoring fura-2 fluorescence at 500 nm [excitation wavelengths of 340 (F340) and 380 nm (F380)] as described previously [12] and [13]. The ratio of the fluorescence intensities observed at the two above mentioned wavelengths (F340/F380) was used as an indicator of the [Ca2+]i. One milliliter of cell suspension containing 5×105 cells was used in each set of experiments.

In addition, three conditions are required for HO: (1) the presence of an osteoinductive factor, (2) chondrocyte progenitor and osteoblast progenitor cells, and (3) an environment permissive to osteogenesis [1]. Once these conditions are met, mesenchymal cells are recruited, RGFP966 mouse which then proliferate and differentiate into chondrocytes and/or osteoblasts, and ultimately induce ectopic bone formation [10]. In this review, we will summarize our current understanding of the pathology and mechanisms of HO, and in particular, endochondral HO. We will then discuss current and future therapies for the HO. Finally, we will explore how lessons learned from HO research can be applied to the dental field. The endochondral

HO process largely recapitulates the cellular events of endochondral Gefitinib supplier ossification in embryonic skeletal development and fracture healing. However, in HO, these cellular events are temporally and spatially unsynchronized. Therefore tissues of HO are disorganized and inhomogeneous. Mature heterotopic bone can also form bone marrow cavities and produce apparently normal bone marrow [11]. Histological evaluation of HO has shown that tissue destruction is followed by cell proliferation

and tissue formation (Fig. 1) [12]. To initiate the process of HO formation, inflammation first occurs in response to stimulations, including surgery, trauma, and viral illnesses [13]. Inflammatory cells such as lymphocytes, macrophages, and mast cells reside in the perivascular region of early HO lesions within skeletal muscle and connective tissue. The presence of inflammatory cells is associated with damage to skeletal muscle cells and tissue hypoxia, both Carbohydrate of which could trigger the proliferation of fibroblastic cells (undifferentiated

mesenchymal cells). This is the initial step of the anabolic phase in early HO lesions [14] and [15]. Tissue degeneration initiates local production, release, or delivery of skeletogenic-inducing factors that leads to recruitment and active proliferation of fibroblastic cells that differentiate into chondrocytes. Cartilaginous tissues are eventually replaced by bone through a normal sequence of endochondral ossification stages, and newly synthesized bone becomes mature and shows lamellar structure [16]. HO originates from several cell sources. These include hematopoietic stem cells, local resident mesenchymal stem cells (MSCs), circulating MSCs, muscle satellite cells, fibroblasts, progenitor cells derived from vessels [17], [18] and [19]. Cell lineage tracing studies were performed to determine the stem/progenitor cells responsible for HO in the BMP-induced HO mouse models [14] and [20]. In these studies, three possible candidates, skeletal muscle progenitor cells (MyoD+), endothelium and endothelial precursors (Tie2+), and vascular smooth muscle cells (SMMHC+) were examined.

“Aneurysm and pseudoaneurysm of brachiocephalic artery are extremely rare conditions. Traumatic injuries can be the cause of it. The symptoms are usually nonspecific. The disease must be timely and properly diagnosed and treated in order to avoid the fatal end. 58 year-old male admitted to the Hospital of Lithuanian University of Health Sciences due to suspicion of mediastinal tumor for diagnostic endobronchial ultrasound procedure (EBUS) in July of 2010. Mediastinal tumor of 3.8 × 3.5 cm was found during chest CT scan one year before in June of 2009. Mediastinoscopy was suggested for diagnosis but not completed due to the cardiovascular problems (low ejection fraction of the left ventricle – 10%). The patient has been suffering from dilative cardiomyophathy and chronic atrial

fibrillation and has been treated with warfarin for three years. The patient used to work as sport trainer, had several chest traumas and surgery due to punctured wound of chest wall 30 years ago. The status of patient gradually deteriorated click here during one year before admission. The main patient’s complain was progressive dyspnea. Objective investigation revealed no major

findings: normal breath sounds, heart rate – 96 bpm, blood pressure – 120/80 mmHg. Chest CT scan in July 2010 showed the mediastinal tumor of the same size. During bronchoscopy at the time of admission smooth intratracheal nodule of 5 mm was found (Fig. 1). Superficial biopsy of polypoid nodule was performed with subsequent answer Morin Hydrate – normal airway mucosa. EBUS procedure was done. No clear lymph node structure or blood flow was detected. Although preliminary diagnosis was mediastinal tumor, the vascular malformation couldn’t be ruled out. One month later massive hemoptysis started. Urgent bronchoscopy revealed large right-sided mass and intratracheal wall dislocation due to the possible mediastinal tumor in the same location as the polyp in the first image (Fig. 2). Repeated chest CT scan (Fig. 3a–c) on August 2010 showed increasing tumor of size 4.0 × 3.2 × 4.0 cm in the mediastinum and pseudoaneurysm of brachiocephalic artery was suspected. The diagnosis was later confirmed by aortography (Fig. 4). The patient underwent successful aneurysmectomy. Aneurysm of brachiocephalic artery is a rare disease and could be caused by variety of diseases.1 and 4 Pseudoaneurysm of brachiocephalic artery is much more rare condition and traumatic injuries are the most frequent cause of this pathology.

To semiquantitatively estimate the contribution of each energy component to the docking score,

a cross-correlation matrix of the values shown in Table 2 was calculated (Table 3). The hydrogen bonding and steric energy components, as well as the molecular weights and numbers of free atom–atom bond torsions (entropic contribution), are related to the docking score energies. Consequently, those features should be Fulvestrant considered carefully in the design of new lead compounds. Knowledge of the biology of the host-parasite relationship is central to establishing a paradigm to treat leishmaniasis. PA synthesis is a metabolic pathway that has been explored for drug development against Trypanosoma and Leishmania ( Colotti & Ilari, 2011). The inhibition of PA synthesis can cause oxidative stress in parasite cells, due to a deficiency in trypanothione production ( Colotti & Ilari,

2011). Arginase from Leishmania is the first enzyme in the PA pathway, and blocking it can lead to oxidative stress and promote infection control. In a study of 105 selleck chemical natural compounds, the leishmanicidal activity of the flavonoids fisetin, quercetin, luteolin and 7,8-dihydroxyflavone showed high potency against the amastigotes of L. (L.) donovani ( Tasdemir et al., 2006). These four compounds also showed potential as inhibitors of ARG-L. Fisetin is a flavonoid present in strawberries; quercetin is abundant in onions and broccoli, Calpain and luteolin can be found

in celery, green pepper, parsley and chamomile tea (Shimoi et al., 1998). In this study, we observed that fisetin is a flavonoid that possesses a high potency in arginase inhibition. Fisetin was the most potent arginase inhibitor, with four and ten times higher potency than quercetin and luteolin, respectively. Comparing the structures of these flavonoids revealed that the hydroxyl group at position 3 contributed significantly to the inhibitory activity of arginase, while the hydroxyl at position 5 did not. In the absence of a catechol group on the galangin, arginase inhibition declined sharply, suggesting that the catechol group is important for inhibition activity. The absence of a hydroxyl group at position 3 and catechol on the apigenin inhibited only 6% of ARG-L at 125 μM. C-glycosylation on the isoorientin (luteolin-6-C-glucoside) and the orientin (luteolin-8-C-glucoside) did not enhance arginase inhibition. In contrast, the 7,8-dihydroxyflavone showed an IC50 of 12 μM when the hydroxyl at position 3 and the catechol group were absent. These data indicate that position 8 enhanced the inhibition activity of this compound. The inhibition of ARG-L increased due to the hydroxylation of the phenyl group of molecules hydroxylated at positions 3, 5, and 7, such as in galangin (IC50 100 μM), kaempferol (IC50 50 μM) and quercetin (IC50 4.3 μM).

We therefore recommend (i) increased effort on sampling and testing crop material from the market; (ii) testing for possible dose–response effects of chemical residues in long-term feeding studies; (iii) inclusion

of pesticide residue measurements and safety testing in the regulatory system for risk-assessment and (iv) further research on the indirect ecological effects of herbicides and pesticides, i.e., on ecological interactions in the soil community with possible effects on nutrient uptake and plant composition.

“The co-evolution of mammalian-microbial symbiosis is accompanied by extensive interactive modulations of metabolism and physiology, facilitated by the

crosstalk between the host and symbiotic community. Microbial symbionts often provide traits that their hosts have not evolved on their own, and may synthesise essential amino acids and vitamins or process otherwise indigestible components in the diet, such as plant polysaccharides (Flint et al., 2008 and Turnbaugh et al., 2007). The composition of intestinal microbial communities is highly variable (Turnbaugh et al., 2007), and Trametinib in vitro can be significantly affected by alterations in diet (Flint et al., 2008). Interactive modulations of individuals with variations in their microbial symbionts are likely to affect human health and disease (Turnbaugh et al., 2007). The interactive modulations affecting human health are considerably engaged by beneficial microbial symbionts such as Lactobacilli and Bifidobacteria, which are currently the most marketed probiotic bacteria worldwide ( Saulnier, Spinler, Gibson, & Versalovic, 2009). The beneficial microbial symbionts are responsible for preventing infection, enhancing the immune system, and providing increased nutritional value to food ( Fukuda et al., 2011, Vorinostat chemical structure Saulnier et al., 2009 and Ventura et al., 2009).

The growth and activity of these beneficial microbial symbionts is enhanced by prebiotic foods, such as fructo-oligosaccharide (FOS) and galacto-oligosaccharides, in the human gastrointestinal tract ( Saulnier et al., 2009). Therefore, evaluation of the effects of prebiotic foods on the dietary interactive modulations of the host and the beneficial microbial symbionts are important for human health. Some foods and their components are customarily considered to play an important role in human health. For example, Japanese bunching onion (JBO) (synonym for welsh onion; Allium fistulosum L.), an edible perennial plant, is considered to be beneficial for human health in Japan. The edible portions of the JBO are the green stalk and the white bulb, which are used as ingredients in Asian cuisine, especially in East and Southeast Asia.

0 cm × 6.0 cm (Ghose, 1987). One millilitre of a sodium citrate buffer solution with pH of 4.8 at 50 mM, 0.5 mL of enzyme extract and

a filter paper strip have been added to the tube containing the reaction assay. Another tube received the addition of 1 mL of the same buffer solution and 0.5 mL of enzyme extract. The third tube, which was the substratum control, received the addition of a 1.5 mL buffer solution and a filter paper strip. The blank assay contained 0.5 mL of buffer solution LGK-974 in vivo and 0.5 mL of DNS; thus, the samples were left in an incubator at 50 °C for 1 h (SOLAB SL 222/CFR Piracicaba – SP – Brazil). The reaction was interrupted by the addition of 3 mL of DNS. The tubes were then heated in boiling water for 5 min and 20 mL of distilled water were shortly after added for the subsequent measurement of absorbance in the 540 nm range, and finally carried out using a spectrophotometer (BEL PHOTONICS SF200DM – UV Vis – 1000 nm, Osasco – SP – Brazil). The activity of the enzyme xylanase (Ghose, 1987) was determined according to Miller (1959). The reaction consists of mixing 1 mL of culture supernatant (enzyme extract), 1 mL of 1%

xylan (SIGMA) in 0.05 M acetate buffer pH 5.0, and 2 mL of acid 3,5-Dinitrosalicylic (DNS) was incubated KRX-0401 datasheet at 50 °C for 30 min (SOLAB SL 222/CFR Piracicaba – SP – Brazil), and enzyme–substrate system was shaken. The tubes containing the reactions were measurement of absorbance in the 540 nm range, and finally carried out using a spectrophotometer (BEL PHOTONICS SF200DM – UV Vis – 1000 nm, Osasco – SP – Brazil). The standard curve for CMCase and FPase was built from the determination of glucose concentrations from 0.1 to 2.0 g/L by the method of DNS (Miller, 1959). Xylanase for the curve was constructed from the determination from 0.1 to 2 g/L xylose produced per minute. The unit Niclosamide of enzyme activity (U) was defined as the amount of enzyme capable of releasing 1 μmol reducing sugar per minute at 50 °C, where the enzyme activity expressed as U/mL. The absorbance was measured in

a spectrophotometer (BEL SF200DM PHOTONICS – UV Vis – 1000 nm, Osasco – SP – Brazil) at 540 nm for CMCase and FPase, for xylanase was measured at 550 nm. A 23−1 fractional factorial planning added of 4 repetitions in the central point was implemented in order to evaluate the influence of temperature, water content and time in the enzymatic active of CMCase, FPase, and xylanase. The variable level values are shown in Table 1. Three main analytical steps – analysis of variance (ANOVA), regression analysis and plotting of response surface – were performed to obtain an optimum condition for the enzymatic active. First, the results obtained from experiments were submitted to ANOVA Variance analysis, and effects were considered significant at p < 0.02. With a second order polynomial model (Eq.

Ribavirin has also been used in attempts to treat various DNA and RNA virus infections, although acquired resistance to the drug has been demonstrated in various virus populations and in some patients [29]. The development of antiviral drugs targeting viruses classified in the Picornaviridae family is therefore urgently required. In the current study, the antiviral activities of ginsenosides against CVB3, EV71, and HRV3 have been evaluated and compared with the currently used antiviral drug ribavirin, which exhibits some antiviral activity. The results of our study demonstrating the antiviral activities of ginsenosides suggest that the compounds may provide a therapeutic option for the treatment of CVB3, EV71, and HRV3

infection; Compound C datasheet furthermore, the compounds could potentially be effective against Picornaviridae viruses in general. Strong anti-CVB3 and anti-HRV3 activity was demonstrated for PT-type ginsenosides (Re, Rf, and Rg2), ATR inhibitor and ginsenoside Rg2 of the PT type showed anti-EV71 activity, despite its relatively weak activity. By contrast, PD-type ginsenosides (Rb1, Rb2, Rc, and Rd) did not show

any antiviral activity against CVB3, EV71 and HRV3, and even increased the cytotoxicity induced by virus infection. Taken together, these results indicate that the antiviral activities of ginsenosides against CVB3, EV71, and HRV3 appear to be selectively dependent on the type of ginsenosides. Ginsenoside is divided into PD saponin and PT saponin by its chemical structure. The other study group investigated and compared the antiobesity activity of PD-type and PT-type saponins in rats fed a high fat diet. In conclusion, PD- and PT-type saponins have been shown to exert antiobesity effects in the rats fed with a high fat diet by reducing their body weight, their food consumption, and their fat storage. However, PD-type saponins

have more potent antiobesity properties than PT-type saponins [41]. We think our data also demonstrate that antiviral activities are related to the chemical structures. Therefore, further studies are required to explore the detailed antiviral mechanisms of ginsenosides Cell press of the PT type as well as to assess in vivo antiviral activity. The authors declare that they have no competing interests. CVB3 and EV71 were provided by Chungcheongnam-Do Health and Environment Research Institute, Daejeon, South Korea.

It is also possible that the relations between both processing and storage with gF are accounted for by different contributions from attention

control, capacity, and secondary memory. That is, both processing and storage might actually reflect independent contributions from attention control, capacity, and secondary memory. To examine these notions we had a large number of participants perform multiple complex span, attention control, capacity, secondary memory, and gF tasks and we used latent variable techniques PI3K inhibitor to examine the pattern of relations among the different constructs. In order to derive latent variables for the constructs of interest, multiple indicators of each cognitive construct were used. This was done in order to ensure that any lack of a relation found would not be due to unreliability or idiosyncratic task effects. Therefore, multiple measures of each cognitive construct were used to create latent variables. By examining

a large number of participants MAPK Inhibitor Library solubility dmso and a large and diverse number of measures we should be able to better characterize the nature of individual differences in WM and its relation with gF. A total of 171 participants (63% female) were recruited from the subject-pool at the University of Oregon and from the local Eugene, OR community. Participants were between the ages of 18 and 35 (M = 21.4, SD = 3.5) and received $10 per hour for their participation. After signing informed consent, all participants completed color capacity, operation span, antisaccade, Raven, delayed free recall, shape capacity, symmetry span, and number series in Session 1. In Session 2, all participants completed space capacity, reading span, disengagement, Cattel’s Culture Fair Test, paired associates, orientation capacity, picture source recognition, and motion capacity. In Session 3, participants completed the 48 drop task and the change detection task. All tasks were administered in the order listed above. Ospan. Participants

solved a series of arithmetic problems while trying to remember a set of unrelated letters (F, H, J, K, L, N, P, Q, R, S, T, Y). Before beginning the real trials, participants performed three practice sections. The first Sitaxentan practice was simple letter span. A letter appeared on the screen and participants were required to recall the letters in the same order as they were presented. In all experimental conditions, letters remained on-screen for 1000 ms. At recall, participants saw a 4 × 3 matrix of letters. Recall consisted of clicking the box next to the appropriate letters (no verbal response was required) in correct order. The recall phase was untimed such that participants had as much time as needed to recall the letters. After recall, the computer provided feedback about the number of letters correctly recalled in current set.

Moreover, the natural structural heterogeneity that develops after many decades of stand development,

through accumulation of the effects of both competitive and non-competitive mortality, can be achieved fairly rapidly, thus accelerating the restoration process (O’Hara et al., 2010). Large woody debris is an important habitat element that can be abundant in passively selleck screening library managed stands, but is often depleted in managed stands (Harmon et al., 1986 and Grove and Meggs, 2003). The depletion reflects the relatively short rotation or cutting cycle lengths of managed stands, compared to the natural life spans of trees, such that significant amounts of large deadwood does not have time to develop. Additionally, dead trees may not be left as biological legacies (sensu Franklin et al., 2000) in harvested stands. Moreover, living but decadent trees in the process of decline, decay, and eventual mortality, are abundant in natural forests, but managed against in traditional commercial forestry (e.g., Fridman and Walheim, 2000 and Kruys RGFP966 in vivo et al., 2013). In fact, traditional thinning is often used to improve and standardize tree quality and form, such that

poor quality trees (e.g., those with cavities, large branches, or decay pockets) may be preferentially removed ( Graves et al., 2000). Given the importance of dead and dying trees in forest ecosystems as habitat for many other organisms (Harmon et al., 1986 and Jonsson et al., 2005), a restoration program might include active techniques, beyond time, to add these structural elements into managed stands. One such approach is the inclusion of dead and Phenylethanolamine N-methyltransferase dying trees in retention harvesting prescriptions. Conceptually, variable retention harvesting is meant to consider and include more than just large live trees,

but also other structural elements that are retained in the harvested stand as legacies, including standing and downed deadwood (Franklin et al., 1997 and Grove and Meggs, 2003). A restoration program might include actions such as deliberate killing of living trees, or injuring them to induce decline, with the goal of creating cavity trees and dead wood in its various forms in established stands (Laarmann et al., 2009, Vanha-Majamaa et al., 2007 and Gibbons et al., 2010). Alternatively, artificial cavities have been successfully created for some endangered species (Hooper and McAdie, 1996 and Lindenmayer et al., 2009). Leaving high stumps after harvest benefits saproxylic beetles by providing breeding habitat (e.g., Lindhe and Lindelöw, 2004). Restoring structural heterogeneity at multiple scales often is a component of habitat restoration for birds and other animals. Complex vegetation structures can be especially important for conservation of some top predators, but a diversity of structures may be needed to fulfill the habitat requirements of their prey.

i.d., 5 μm, Torrance, CA, USA) were used for HPLC analysis. MicroTOF-Q II LC/MS (Bruker Daltonics, Bremen, Germany) was used for the LC/MS analysis. A549 lung cancer cells line was purchased from the American Type Culture Collection (ATCC, Manassas, VA, USA). DMEM/F12 media, fetal bovine serum, penicillin/streptomycin antibiotics, and phosphate buffer saline (PBS) were purchased from

Gibco (Grand Island, NY, USA). 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium CDK phosphorylation bromide (MTT) was purchase from Amresco (Solon, OH, USA), and 2,2-diphenyl-1-picrylhydrazyl radicals (DPPH), DMSO were purchased from Sigma Aldrich (St. Louis, MO, USA). SpectraMax 340PC384 microplate reader (Molecular Devices, Sunnyvale, CA, USA) was used to measure the absorbance of the samples. HPLC solvents and other reagents were purchased from Duksan (Ansan, Korea). Ginsenoside standards were isolated and identified from KG and VG in our laboratory [2] and [12]. Dried VG, including radix, rhizome, and hairy root, was ground and sieved to get the powder of 355–425 μm. A 150 mg portion of each powdered VG sample was put into stainless steel vessel with 1.5 mL

of distilled water. The vessel was closed tightly and AUY-922 solubility dmso heated in an oven for 2 h, 4 h, 6 h, 8 h, 10 h, 12 h, 14 h, 16 h, 18 h, or 20 h at 120°C. After heating, the samples were lyophilized to yield a dried powder, which were extracted three times by ultrasonication at 65°C for 3 h, 1.5 h, and 1 h, using 10 mL, 10 mL, and 5 mL of methanol (MeOH), respectively. The combined extract was centrifuged and then made up to 25 mL with MeOH. A 2 mL of the MeOH extract of each sample was dried under nitrogen stream. The residue was dissolved in 1 mL of MeOH and then filtered through a 0.45 μm membrane filter prior to HPLC analysis. The MeOH extract of each sample was dried under

nitrogen stream, then dissolved in DMEM/F12 media containing 0.1% DMSO to get various concentrations for the cell proliferation analysis. The MeOH extract of each sample was used at the final concentration 3-mercaptopyruvate sulfurtransferase equivalent to 6 mg of dried VG powder in 1 mL of MeOH. The reported method [15] was applied for the HPLC analysis of ginsenosides with a slight modification. Separation was achieved by using Phenomenex C18 column (250 mm × 4.6 mm. i.d., 5 μm) and the following gradient program with 5% acetonitrile (A) and 95% acetonitrile (B): 0–20 min (85–80% A); 20–45 min (80–52.5% A); 45–55 min (52.5–0% A); 55–65 min (0% A). Flow rate was set at 1 mL/min and injection volume was 20 μL. ELSD was set to a probe temperature of 80°C, and nebulizer gas (N2) flow was adjusted to 1.5 L/min. A549 lung cancer cells were cultured in DMEM/F12 medium supplemented with 10% fetal bovine serum and 1% antibiotics in a humidified atmosphere of 5% CO2 at 37°C. Antiproliferative activity was measured by a previously reported method [16]. A549 lung cancer cells at 104 cells/well were seeded in 96-well plates and incubated for 24 h.
