7 μg/mL [7]; and 4) the UTI+TXT group was treated with UTI and TXT at the same concentrations described above. All drugs were prepared 6 h before administration. 1.5.2 Animal experiment

After being harvested, the cell lines washed Selleckchem BMS202 with PBS and resuspended in serum-free RPMI-1640 medium. The cell concentration was adjusted to 1 × 107 cells/mL. Cells were inoculated subcutaneously into the right armpits of 45 nude mice at 0.2 mL/mouse. 21 days after inoculation, animals with tumor volumes ≥ 500 mm3 were chosen in the study. A total of 28 animals were randomly divided into four groups for subsequent intraperitoneal injections as follows: 1) The UTI group (n = 7) was injected with UTI at 1600 U/day/mouse for 20 consecutive days [4]; 2) the TXT group (n = 7) was injected with TXT at 20 mg/kg on days 1, 7, and 14 [7]; 3) the UTI+TXT group (n = 7) was injected with UTI and TXT at dosages of UTI and TXT groups described in 1.5.1; and 4) the control group (n = 7) was injected with an equal volume of saline in 1.5.1 for 20 days. The animals were sacrificed for sample

Rabusertib order collection 21 days after administration. Minimum (D) and maximum (L) tumor diameters were measured to calculate the tumor volume (V), drawn the growth curve, and calculate the tumor learn more inhibition rate. The q was also calculated via King’s formula (a is the inhibition rate of UTI, b is the inhibition rate of TXT, and c is the inhibition rate of group UTI+TXT; q > 1.15 represents a synergistic effect, 1.15 > q > 0.85 represents

an additive effect, and q < 0.85 represents an antagonistic effect). The related formulas are as follows: 1) tumor volume (cm3) = (L2 × D)/2; 2) tumor inhibition rate (%) = [1 -(starting average tumor volume of treatment group - ending average tumor volume of treatment group)/(starting average tumor volume of control group - ending average tumor volume of control group)] × 100%; 3) q = c/ [(a + b) - a × b]. After being harvested, MDA-MB-231 cells were washed twice with PBS, and PTK6 then resuspended in serum-free RPMI-1640 medium. The cell concentration was adjusted to 2.5 × 1010 cells/L. Cells were inoculated subcutaneously into the right armpits of 50 nude mice at 0.2 mL/mouse. The method was the same as the experiment described above. 1.6 Detection of cell proliferation by MTT Cultured cells were inoculated into 96-well plate at 1.5 × 103 cells/well and divided into four groups as described in 1.5. Cells were cultured for 24, 48, or 72 h in a 37°C humid environment with 20 μL MTT solution (5 mg/mL). After another 4 h of culturing at 37°C, the culture medium was removed, 200 μL dimethyl sulfoxide was added to each well, and the plates were incubated for 10 min with shaking.

We experienced a case of MLL occurring in a 28-month-old patient. To our knowledge, this represents the youngest case of MLL yet reported. In this patient, no data were available concerning

a possible past history of Cediranib (AZD2171) shearing injury. The patient had no abrasions or bruises on initial physical examination, and MLL was therefore not considered in the initial diagnosis. For this reason, the patient initially received conservative management only for the pelvic fracture. Moreover, this patient displayed no fluid collection other than the retroperitoneal hematoma detected on CT scans on admission and on day 3. This patient therefore posed a diagnostic challenge. On day 4, the patient presented with skin color change with swelling and fluctuation. This led to the speculation that not only did fluid collection occur as a result of persistent bleeding from the pelvic fracture in the dead space caused by detachment after the onset of initial shearing injury but also that the resulting mass effect led to the occurrence of skin necrosis. Pediatric cases of MLL are characterized by the relatively high vulnerability of young patients to trauma. It is also noteworthy that the diagnosis of MLL is often delayed in very young patients, for whom history taking regarding shearing injury and the duration of symptoms is often difficult [12, 17, 22, 38].

Transmission electron microscopy (TEM) and scanning near-field optical microscopy (SNOM) techniques were used to provide simultaneous investigation on the micro-structure and crystallinity, micro-PL spectrum, and

mode-selected mapping image. Both near-bandgap emission and trapped-state emission of ZnSe are observed in Mn-ZnSe nanobelts obtained using Mn powder as dopant. However, the Mn ion transition emission cannot be observed in this ZnSeMn nanobelt. Using manganese chloride (MnCl2) as dopant, strong Mn ion transition emission and weak near-bandgap emission are selleck chemical observed. We can also observe the strong Mn ion transition emission and weak near-bandgap emission in the Mn-ZnSe nanobelts obtained using manganese acetate as dopant. More interestingly, the Mn ion transition emission can split into multi-mode emission due to multi-Fabry-Pérot cavity effect in the nanobelt. Raman spectrum was used to confirm the effective doping. These results are helpful in understanding the effect of dopant on the optical micro-cavities and multi-mode emission. These Mn-ZnSe nanostructures can find promising applications in multicolor emitter or wavelength selective photodetector. Methods The 1D Mn-ZnSe nanobelts were synthesized by a simple thermal evaporation method. Commercial grade mixed powder of ZnSe and Mn or MnCl2 or manganese acetate (Mn(CH3COO)2) with a

weight ratio of 5:1 was used as source material. The obtained samples were labeled selleckchem as ZnSeMn, , , respectively. The other synthesis processes are similar with our previous report [16]. The evaporation temperature, growth temperature, and growth time are set to 900°C, 600°C, and 45 min, respectively. A yellow product deposited on the silicon wafer after the furnace cools down to room temperature. For comparison, the pure ZnSe nanobelts were also synthesized using ZnSe powder as source material. XRD (D/max-5000, Rigaku Corporation, Tokyo, Japan), E-SEM (QUANTA 200, FEI, Hillsboro, OR, USA), energy dispersive X-ray spectroscopy (EDS; attached to SEM), and TEM

(JEM-3010, JEOL Ltd., Tokyo, Japan) were used to examine the phase structure, crystallinity, and composition of the as-prepared nanobelts. Raman spectroscopy was performed in a confocal microscope (LABRAM-010, HORIBA Ltd., Kyoto, Japan) using He-Ne laser (632.8 nm) as selleck compound excitation light source. The Loperamide PL and corresponding mapping were obtained by SNOM (alpha 300 series, WITec GmbH, Ulm, Germany) with He-Cd laser (325 nm) as excitation source at room temperature. In all optical experiments, the excitation signal illuminated perpendicularly onto the sample surface. Results and discussion The XRD patterns of pure and doped ZnSe nanobelts are shown in Figure 1. All of the XRD pattern peaks of pure and doped ZnSe nanobelts are in agreement with the standard values (JCPDS card no. 37–1463), see Figure 1a. There are no diffraction peaks of Mn or MnSe in the doped samples.

During the photocatalytic reduction process, photocatalyst nanoparticles are assembled onto graphene sheets to form photocatalyst-graphene composites. Herein, we report the synthesis of SrTiO3-graphene nanocomposites via the photocatalytic reduction method. The photocatalytic activity of the composites was evaluated by the degradation of acid orange 7 (AO7) under ultraviolet (UV) light irradiation, and the photocatalytic find more mechanism

involved was discussed. Methods SrTiO3 nanoparticles were synthesized via a polyacrylamide gel route as described in the literature [25]. The graphene oxide used in this research was purchased from Nan-Jing XF Nano Materials Tech Co. Ltd. (Nanjing, China). SrTiO3-graphene composites were prepared via a photocatalytic reduction route. A certain amount of graphene oxide was dispersed in 50 mL distilled water, followed by ultrasonic treatment of the suspension for 30 min. Then, 0.1 g SrTiO3 nanoparticles and 0.0125 g ammonium oxalate (AO) were added to the suspension PF-6463922 clinical trial under magnetic stirring. After GS-9973 stirring for 10 min, the mixture was purged with nitrogen and exposed to UV light irradiation from

a 15-W low-pressure mercury lamp for 5 h under mild stirring. During the irradiation, the color of the mixture changed from brown to black, indicating the reduction of the graphene oxide. After that, the product was separated from the reaction solution by centrifugation at 4,000 rpm for 10 min, washed several times with distilled water and absolute ethanol, and then dried in a thermostat drying oven at 60°C

for 4 h to obtain SrTiO3-graphene composites. A Nintedanib (BIBF 1120) series of samples were prepared by varying the weight fraction of graphene oxide from 2.5% to 10%. The photocatalytic activity of the samples was evaluated by the degradation of AO7 under UV light irradiation of a 15-W low-pressure mercury lamp (λ = 254 nm). The initial AO7 concentration was 5 mg L-1 with a photocatalyst loading of 0.5 g L-1. Prior to irradiation, the mixed solution was ultrasonically treated in the dark to make the photocatalyst uniformly dispersed. The concentration of AO7 after the photocatalytic degradation was determined by measuring the absorbance of the solution at a fixed wavelength of 484 nm. Before the absorbance measurements, the reaction solution was centrifuged for 10 min at 4,000 rpm to remove the photocatalyst. The degradation percentage is defined as (C 0 - C t) / C 0 × 100%, where C 0 and C t are the AO7 concentrations before and after irradiation, respectively. To investigate the photocatalytic stability of the SrTiO3-graphene composites, the recycling tests for the degradation of AO7 using the composite were carried out. After the first cycle, the photocatalyst was collected by centrifugation, washed with water, and dried.

(a) Graphite, (b) graphene oxide film, (c to e) graphene films (reduced by ascorbic acid), and (f to j) graphene-Ag composite films (the amount of AgNO3 was from 2 to 300 mg in each film). The mechanical properties of graphene oxide films and graphene films have also been studied, as shown in Figure 10

and Table 2. Compared with graphene LBH589 oxide films, graphene films exhibit enhanced mechanical behaviors. After being reduced for 5 h, the stress of the obtained graphene films increases from 33 to 60 MPa (increased by 82%), and the strain decreases from 1.3% to 0.9%. The preliminary results, a considerable improvement in the Young’s modulus of graphene films increased by 136% (up to 7.8 MPa), are encouraging. From Table 2, it can be also observed that the optimal reduction period for the preparation of graphene films is 5 h. Moreover, after selleck Ag particles are decorated, there is little change in the mechanical properties of graphene-Ag composite films compared with the corresponding graphene films. Figure 10 Mechanical curves of the films tested by DMA. (a) Graphene oxide films and (b to d) graphene film (reduced by ascorbic acid). Table 2 Mechanical properties of

graphene oxide films and graphene films reduced for different times Sample Strain (%) Stress (MPa) Modulus (GPa) (a) GO 1.3 ± 0.2 33.0 ± 1.3 3.3 ± 0.3 (b) 1 h 0.8 ± 0.1 49.3 ± 0.9 6.8 ± 0.1 (c) 5 h 0.9 ± 0.1 60.2 ± 0.6 7.8 ± 0.1 (d) 12 h 0.9 ± 0.1 32.5 ± 1.4 3.9 ± 0.2 Finally, the sheet this website resistance of these films was measured using the four-probe detector as shown in Figure 11. The electrical properties can be tuned by the addition of a given amount of Ag particles.

When the amount of AgNO3 is no more than 10 mg, the sheet resistance decreases; on the other hand, when the amount of AgNO3 is 20 mg, the sheet resistance increases. When the optimal amount of AgNO3 is 10 mg, a minimum sheet resistance of approximately 600 Ω/□ for graphene-Ag composite films is obtained. It can be found that the conductivity of the resultant graphene-Ag composite films can be improved greatly via the uniform decoration of Ag particles. Figure 11 The electrical properties of the graphene-Ag composite films. Conclusions In summary, we have demonstrated that graphene-Ag composite films are fabricated in a Sitaxentan large scale using a facile chemical reduction method. The graphene oxide sheets can be easily assembled to form free-standing graphene oxide films during the volatilization process on PTFE hydrophobic substrate. After dipping the graphene oxide films into the Ag+ aqueous solution, Ag particles can be uniformly distributed on the surface of graphene films using ascorbic acid as a reducing agent. The morphology of the composite films can be maintained during the reduction process. The obtained films have been characterized by AFM, SEM, XRD, Raman, FTIR, TGA, DMA, and a four-probe detector.

The methylation status of PCDH8 was detected using primers specific for PCDH8 unmethylated and methylated sequences respectively, as our reported previously [18]. The following primers were used: unmethylated:

forward 5’- GGTGGTTATTGGTTATTTGGTTT-3’ and reverse 5’- CCAACAAACTCTAAAAACACACA-3’; methylated: forward 5’- CGGTTATTGGTTATTCGGTTCC-3’ Apoptosis inhibitor and reverse 5’- ACGAACTCTAAAAACGCGCG -3’. The PCR amplification of the modified DNA consisted of one cycle of 95°C for 5 min, 40 cycles of 95°C for 30 s, 60°C for 30 s, and 72°C for 30 s, and 1 cycle of 72°C for 5 min. Water blanks were included with each assay, in vitro methylated DNA and unmethylated DNA (New England Biolabs, Beverly, MA, USA) was used as methylation and unmethylation positive control. PCR products were separated

in 2% agarose gel, stained with ethidium bromide, and visualized under ultraviolet illumination for analysis. Samples were scored as methylation positive when methylated alleles were present in the methylated DNA lane and methylation negative when bands were present only in the unmethylated DNA lane [18]. Statistical analysis Statistical analysis was conducted using SAS version 8.0 (SAS Institute, Cary, N.C., USA). Fisher’s exact test was used to assess the difference of PCDH8 methylation status between NMIBC patients and controls. Chi-square test was used to assess the relationship between PCDH8 methylation and clinicopathologic features. Kaplan-Meier survival analysis and log-rank test were SIS3 purchase used to assess the differences of recurrence-free survival, progression-free survival and this website five-year overall survival between patients with PCDH8 methylated and unmethylated. Multivariate Cox proportional hazard model analysis was used to assess the independent prognostic effect of PCDH8 methylation. A

two-sided p value < 0.05 was considered statistically significant. Results The methylation status of PCDH8 in NMIBC and normal bladder epithelial tissues In the current study, the methylation status of PCDH8 in NMIBC and normal bladder epithelial tissues was examined by MSP. We found that PCDH8 methylation occurred in 128 (54.9%) patients with NMIBC (Figure 1). However, no methylation was detected in controls, and the difference between these two groups was statistically AMP deaminase significant. The result is shown in Table 1. Figure 1 Representative MSP results for PCDH8 methylation in tumor-derived DNA samples from patients with NMIBC. W: water; P: positive control; N: negative control; M: methylated; U: unmethylated.

Unlike its phylogenetic relatives GM1 was unable to grow with either cis-dichloroethene or naphthalene as sole carbon source (data not shown). Figure 2 16S rRNA phylogenetic tree of arsenite-oxidising strain GM1 and published Polaromonas species. GenBank accession numbers are in parentheses. Significant bootstrap values (per 100 trials) are shown. The tree is rooted with the 16S rRNA gene sequence of p38 MAPK pathway Alcaligenes find more faecalis (AY027506) (not shown). Growth of GM1 was tested at 4°C, 10°C and 20°C in a minimal

salts medium (MSM) with 0.04% (w/v) yeast extract in the presence and absence of 4 mM arsenite as described previously [15] (Note: GM1 was unable to grow chemolithoautotrophically with arsenite). Under all conditions arsenite was oxidised RG7112 nmr to arsenate and oxidation occurred in the early exponential phase of growth (Figure 3). The generation time of

GM1 was shorter in the absence of arsenite, and decreased with increasing temperature (without arsenite at 4°C, 10°C and 20°C: 19 h, 16.5 h and 7 h, respectively; with arsenite at 4°C, 10°C and 20°C: 21.5 h, 17.7 h and 8.5 h, respectively). GM1 did not grow above 25°C. To date, only one arsenite oxidiser has been demonstrated to grow below 20°C [16]. This organism, a chemolithoautotrophic arsenite oxidiser designated M14, is a member of the Alphaproteobacteria related to Sinorhizobium species. M14′s temperature range was between 10°C and 37°C with an optimum of 22°C [16]. GM1 is the first reported arsenite oxidiser capable of growth below 10°C. Figure 3 Growth curves of GM1 grown at 4°C, 10°C and 20°C in the Minimal Salts Medium (MSM) with 0.04% (w/v) yeast extract. With 4 mM arsenite, closed circle; without arsenite, open circle; arsenite concentration, closed square. Error bars are the standard deviation of multiple experiments. The arsenite-oxidising ability of GM1 was further confirmed by testing for arsenite oxidase (Aro) activity in cells grown in the MSM with 4 mM arsenite and 0.04% (w/v)

yeast extract. Aro activity was measured at room temperature (i.e. 24°C) in its Cetuximab optimal buffer, 50 mM 2-(N-Morpholino)ethanesulfonic acid (MES) (pH 5.5) (data not shown). Aro activity was higher when GM1 was grown at 10°C (0.334 U/mg) compared with growth at 4°C (0.247 U/mg) and 20°C (0.219 U/mg) which were comparable. In growth experiments although all the arsenite is oxidised to arsenate in the early exponential growth phase the highest Aro activity was observed in the stationary phase of growth (i.e. 0.334 U/mg compared with 0.236 U/mg at early exponential phase). In most cases, arsenite is required in the growth medium for arsenite oxidase gene expression [6]. There are two exceptions, Thiomonas sp. str. 3As and Agrobacterium tumefaciens str.

Figure 5 check details Relative βSelleck 5-Fluoracil -lactamase activity in PAO ampP and PAO ampG mutants.

Assays were performed on the parental PAO1, and the mutants, PAOampP and PAOampG in the presence of benzyl-penicillin at a concentration gradient of 0 to 125 μg/ml. Cultures at OD600 of 0.6-0.8 were induced for three hours before harvesting. Assays were performed on sonicated lysate using nitrocefin as a chromogenic substrate. The β-lactamase activity of PAO1 at 100 μg/ml of benzyl-penicillin was taken as 100%. Each value is the mean of at least three independent experiments. The asterisk refers to p-values of < 0.05 with respect to PAO1, which were calculated using the two-tailed Student's t-test. In PAOampG, the initial increase of β-lactamase activity was observed at 25 μg/ml, suggesting that this burst of β-lactamase production is ampG-independent (Figure 5). However, unlike {Selleck Anti-diabetic Compound Library|Selleck Antidiabetic Compound Library|Selleck Anti-diabetic Compound Library|Selleck Antidiabetic Compound Library|Selleckchem Anti-diabetic Compound Library|Selleckchem Antidiabetic Compound Library|Selleckchem Anti-diabetic Compound Library|Selleckchem Antidiabetic Compound Library|Anti-diabetic Compound Library|Antidiabetic Compound Library|Anti-diabetic Compound Library|Antidiabetic Compound Library|Anti-diabetic Compound Library|Antidiabetic Compound Library|Anti-diabetic Compound Library|Antidiabetic Compound Library|Anti-diabetic Compound Library|Antidiabetic Compound Library|Anti-diabetic Compound Library|Antidiabetic Compound Library|Anti-diabetic Compound Library|Antidiabetic Compound Library|Anti-diabetic Compound Library|Antidiabetic Compound Library|Anti-diabetic Compound Library|Antidiabetic Compound Library|buy Anti-diabetic Compound Library|Anti-diabetic Compound Library ic50|Anti-diabetic Compound Library price|Anti-diabetic Compound Library cost|Anti-diabetic Compound Library solubility dmso|Anti-diabetic Compound Library purchase|Anti-diabetic Compound Library manufacturer|Anti-diabetic Compound Library research buy|Anti-diabetic Compound Library order|Anti-diabetic Compound Library mouse|Anti-diabetic Compound Library chemical structure|Anti-diabetic Compound Library mw|Anti-diabetic Compound Library molecular weight|Anti-diabetic Compound Library datasheet|Anti-diabetic Compound Library supplier|Anti-diabetic Compound Library in vitro|Anti-diabetic Compound Library cell line|Anti-diabetic Compound Library concentration|Anti-diabetic Compound Library nmr|Anti-diabetic Compound Library in vivo|Anti-diabetic Compound Library clinical trial|Anti-diabetic Compound Library cell assay|Anti-diabetic Compound Library screening|Anti-diabetic Compound Library high throughput|buy Antidiabetic Compound Library|Antidiabetic Compound Library ic50|Antidiabetic Compound Library price|Antidiabetic Compound Library cost|Antidiabetic Compound Library solubility dmso|Antidiabetic Compound Library purchase|Antidiabetic Compound Library manufacturer|Antidiabetic Compound Library research buy|Antidiabetic Compound Library order|Antidiabetic Compound Library chemical structure|Antidiabetic Compound Library datasheet|Antidiabetic Compound Library supplier|Antidiabetic Compound Library in vitro|Antidiabetic Compound Library cell line|Antidiabetic Compound Library concentration|Antidiabetic Compound Library clinical trial|Antidiabetic Compound Library cell assay|Antidiabetic Compound Library screening|Antidiabetic Compound Library high throughput|Anti-diabetic Compound high throughput screening| PAO1, the induction level failed to increase after 25 μg/ml of benzyl-penicillin and even significantly decreased with addition of increased concentrations of benzyl-penicillin (Figure 5). Mutation of ampP also prevented maximum induction of β-lactamase, but the defect was

not quite as severe as in PAOampG. In PAOampP, the pattern of β-lactamase induction was very similar to PAO1 at concentrations of benzyl-penicillin up to 50 μg/ml (Figure 5). However, unlike PAO1, addition of benzyl-penicillin at concentrations greater than 50 μg/ml failed to further

induce production of β-lactamases (Figure 5). Thus, low induction is independent of ampG or ampP. The observation that PAOampP exhibited higher levels of β-lactamase expression at higher concentrations of benzyl-penicillin may suggest that ampG plays a greater role at higher concentrations of β-lactam. Most of the β-lactamase activity of P. aeruginosa can be attributed to AmpC, however, P. aeruginosa does contain another Sinomenine chromosomally encoded β-lactamase, PoxB [9, 26]. To further analyze if the loss of β-lactamase induction in the PAOampG and PAOampP strains was due to loss of AmpC function, the ampC promoter (P ampC ) activity was measured in PAO1, PAOampG, and PAOampP. As expected, upon treatment with benzyl-penicillin, P ampC -lacZ activity increased approximately 15-fold (Figure 6). Benzyl-penicillin dependent induction of P ampC -lacZ was lost in PAOampG or PAOampP (Figure 6). Figure 6 Activity of the ampC promoter. Promoter activity of the ampC gene was analyzed using lacZ transcriptional fusions integrated at the att locus of PAO1, PAOampR, PAOampG and PAOampP (see Materials and Methods and text for details). Cells were grown to an OD600 of 0.6 – 0.8, at which time cultures were divided into two and one set treated with 100 μg/ml benzyl-penicillin. After three hours, cells were harvested and β-galactosidase activity assayed as described [10]. Each value is the mean of at least three independent experiments.

pylori as a class I human carcinogen, it now is well accepted that gastric infection https://www.selleckchem.com/products/BIBW2992.html by H. pylori is a risk factor for development of gastric cancer [8]. Although the precise pathogenetic role of H. pylori in gastric carcinogenesis remains unclear, it has been clarified that this organism contributes to modifications in epithelial cell proliferation, which may be the initiating event in a cascade culminating in the development of gastric cancer [9], but

it is not known whether the increased risk is due to the presence of mutant p53 generated by chronic gastritis or to a direct action of the bacteria on the p53 oncogene [10, 11]. The p53 gene mutation is associated with approximately 70% of tumors of different orignis [12, 13]. p53 gene serves as a “”gatekeeper of the cell”", for its role in preventing the accumulation of genetic alterations through the regulation of critical checkpoints between the end of G1 and the beginning of S to redirect cells with a mutation in the genome toward apoptosis or programmed cell death. This key oncogene thus prevents the perpetuation of a defective genome AZD5363 cost and the development of a cancer [14]. Several recent studies have been published on the presence of p53 in patients with H. pylori infection, stomach cancer, or both. However, the conclusions are contradictory, and it has

been difficult to develop a single coherent Bafilomycin A1 datasheet hypothesis that can account for all findings communicated to date [15]. Palli et al [16] found p53 mutants in 33 of Sitaxentan 105 cases of gastric cancer and Domek et al [17] worked with the hypothesis that tumorigenesis involves

deregulation of cell proliferation and apoptosis. These researchers investigated cell proliferation and apoptosis in the gastric epithelium of children infected with H. pylori, and found that the apoptotic index was significantly higher in patients with H. pylori gastritis than in patients with secondary gastritis or healthy control subjects. They also reported that apoptosis decreased when the bacterial infection was eradicated. Wu et al, reported the existence of different pathways of gastric carcinogenesis in different histological subtypes of gastric cancer and its progression, in which H. pylori infection can play an important role [18]. Hibi et al, concluded that persistent H. pylori infection caused gastritis, with degeneration and regeneration of the epithelium that increased cell proliferation and the accumulation of p53 [19]. This in turn increased instability of the gene, as reflected by the development of carcinoma, using immunohistochemical methods to investigate p53 expression, and concluded that expression is associated with histopathological phenotypes, and that genetic alterations may not be affected by H. pylori infection [20]. Chang et al, noted the possibility that H.
