Mortality of patients with PE at intermediate risk was 21 %. The 30-day mortality rate was significantly higher in h-FABP(+) patients compared to h-FABP(-) patients (9 vs. 50 %, p smaller than 0.001). Multivariate analysis revealed h-FABP as the only 30 day mortality predictor (HR selleck compound 7.81, CI 1.59-38.34, p = 0.01). However, thrl therapy did dot affect the survival of these high-risk patients. Despite, h-FABP was successful to predict 30-days mortality in patients with PE at intermediate risk; it is suggested to be failed in determining the patients who will benefit from thrl therapy.”
“Aim This study investigates

whether a local reninangiotensin system (RAS) exists in mouse colon and whether angiotensin II (Ang II) may play a role in the regulation of the contractile activity. Methods Isometric recordings were performed in vitro on the longitudinal muscle of mouse proximal and distal colon. Transcripts encoding for RAS components were investigated by RT-PCR. Results Ang II caused, in both preparations, a concentration-dependent contractile effect, antagonized by losartan, AT1 receptor antagonist, but not by PD123319,

AT2 receptor antagonist. The combination of losartan plus PD123319 caused no change on the Ang II-induced contraction than losartan alone. Tetrodotoxin, neural blocker, reduced the contractile response to Ang II in the proximal colon, whilst STA-9090 molecular weight the response was abolished in the distal colon. In both preparations, atropine, muscarinic receptor antagonist, or SR140333, NK1 receptor antagonist, reduced the Ang II responses. Ondansetron, 5-HT3 receptor antagonist, SR48968, NK2 receptor antagonist, or hexamethonium, AZD1480 molecular weight nicotinic receptor antagonist,

were ineffective. The joint application of atropine and SR140333 produced no additive effect. Atropine reduced NK1-induced contraction. Transcripts encoding RAS components were detected in the colon samples. However, just AT1A mRNA was expressed in both preparations, and AT2 mRNA was expressed only in the distal colon. Conclusion In the murine colon, local RAS may play a significant role in the control of contractile activity. Ang II positively modulates the spontaneous contractile activity via activation of post-junctional and pre-junctional AT1A receptors, the latter located on the enteric neurones, modulating the release of tachykinins and acetylcholine.”
“The purpose of this study was to examine anti-inflammatory effect of ethanolic extract of Antrodia salmonea (EAS) in the lipopolysaccharide (LPS)-stimulated RAW246.7 macrophages and the carrageenan (Carr)-induced edema paw model, and to clarify its possible molecular mechanisms. Inhibitory effects of EAS were examined on cells proliferation, nitric oxide (NO) production, expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) proteins, and activity of antioxidant enzymes.

“OBJECTIVE. High resolution CT (HRCT) is diagnostic of usual interstitial pneumonia (UIP) if honeycombing is present. However, biopsy-proven UIP also occurs in patients without honeycombing. Identification of specific HRCT patterns may enable specific diagnosis and allow more patients to enter clinical trials. Pattern may also predict prognosis. We sought to identify specific

HRCT patterns in patients with biopsy-proven UIP (2000-2009) and to assess outcomes and serial change in pattern.\n\nMATERIALS AND METHODS. We reviewed the HRCT findings in 44 patients with biopsy-proven UIP BMS-777607 in vivo and identified four distinct patterns: classic UIP (cUIP) with honeycombing, fibrosis without honeycombing (FnoH), minimal fibrosis (Fmin), and ground-glass present (GGOp). We reviewed electronic medical records for outcome information and serial HRCT examinations when available.\n\nRESULTS. The extent of fibrosis varied between patterns; findings were

always heterogeneous in the cUIP and FnoH patterns. Some Fmin patients had a more homogeneous appearance. The lower lobes were predominantly affected, but upper lobe Small Molecule Compound Library abnormalities were always present. Mortality from respiratory failure and acute exacerbations occurred regardless of pattern. Serial progression from Fmin to FnoH to cUIP occurred, although in a variable manner. Some individuals had an acute illness (GGOp) as the initial manifestation of UIP.\n\nCONCLUSION. The FnoH pattern may be diagnostic of UIP in the proper clinical setting; heterogeneity of HRCT appearance is critical and has not been previously emphasized. Grouping of patients on the basis of pattern may allow more accurate assessment GDC-0973 cost of treatment effects. Further validation and study of these HRCT patterns is warranted. Histologic UIP predicts clinical course.”
“We analyzed the postal surveys conducted by Japanese Cancer Association (JCA) in 2004 and 2006. This survey aimed to assess JCA members’ behavior and their attitudes toward patients who

are smokers, smoking cessation, and their responsibilities. In the 2006 version, questions were added about hope for various approaches related to smoking and health and the attitudes as medical experts when treating patients. JCA members’ smoking rate was 5.9% in 2004 and 9.0% in 2006. Current smokers were significantly more likely than never or former smokers to disagree or have no opinion with most activities about smoking control such as ‘raising the price of tobacco’ and ‘labeling health warnings describing the harmful effects of tobacco in large letters with clarity for easier reading’, while most members including smokers agree to ban smoking while walking, to educate general people about tobacco and health, to provide an environment where children cannot get tobacco and the information about tobacco and health.

A pooled odds ratio (OR) was calculated using either a random-effect or a fixed-effect model. A total of 16 papers were identified. Among the 11 factors studied, five symptoms demonstrated an increased risk for SDD, including bleeding [OR: 13.617; 95% confidence interval (CI): 3.281, 56.508], vomiting/nausea (OR: 1.692; 95% CI: 1.256, 2.280), abdominal pain (OR: 2.278; 95% CI: 1.631, 3.182), skin rashes (OR: 2.031; 95% CI: 1.269, 3.250), and hepatomegaly (OR: 4.751; 95% CI: 1.769, 12.570). Among the four bleeding-related symptoms including hematemesis, melena,

gum bleeding, and epistaxis, only BI-D1870 manufacturer hematemesis (OR: 6.174; 95% CI: 2.66, 14.334; P smaller than 0.001) and melena (OR: 10.351; 95% CI: 3.065, FRAX597 34.956; P smaller than 0.001) were significantly associated with SDD. No significant associations with SDD were found for

gender, lethargy, retroorbital pain, diarrhea, or tourniquet test, whereas headache appeared protective (OR: 0.555; 95% CI: 0.455, 0.676). The meta-analysis suggests that bleeding (hematemesis/melena), vomiting/nausea, abdominal pain, skin rashes, and hepatomegaly may predict the development of SDD in patients with DF, while headache may predict otherwise.”
“It has been suggested that the left pre-supplementary motor area (pre-SMA) could be implicated in facial emotion expression and recognition, especially for laughter/happiness. To test this hypothesis, in a single-blind, randomized crossover study, we investigated the impact of transcranial magnetic stimulation (TMS) on performances of 18 healthy participants during a facial emotion recognition task. Using a neuronavigation system based on T1-weighted magnetic resonance imaging of each participant, TMS (5 pulses, 10 Hz) was delivered over the pre-SMA or the vertex (control condition) in an event-related fashion after the presentation of happy, fear, and

angry faces. Compared with performances during vertex stimulation, we observed that TMS applied Bucladesine inhibitor over the left pre-SMA specifically disrupted facial happiness recognition (FHR). No difference was observed between the 2 conditions neither for fear and anger recognition nor for reaction times (RI). Thus, interfering with pre-SMA activity with event-related TMS after stimulus presentation produced a selective impairment in the recognition of happy faces. These findings provide new insights into the functional implication of the pre-SMA in FHR, which may rely on the mirror properties of pre-SMA neurons.”
“Chronic kidney disease is often not associated with significant symptoms or abnormalities in common laboratory test results. Diagnosis is supposedly facilitated by calculating the glomerular filtration rate (GFR) from serum creatinine. A reference range GFR. however, does not exclude renal disease, because renal disease causes the subsequent decrease of renal function.

These relate to the resistance of BSCP towards artificial human gastric

juice which is more than 99%. Prebiotic activity tested using BSCP as a carbon source showed significant increase in the growth of B. animalis ATCC 1053, B. longum BB 536 and L. acidophilus ATCC 4356 as compared to the use of FOS. Survivality of S. choleraesuis JCM 6977 was found to be slower in both BSCP and FOS. Study conducted reflects a good sign for the BSCP to be exploited as a promising prebiotic.”
“Background: Different gonadotrophin preparations or different protocols of ovulation induction are powerless to determine a significantly increase in oocyte quality in the majority of aged patients or in patients with repeated failed in vitro fertilization-embryo selleck chemical transfer (IVF-ET) cycles.\n\nInformation Sources: Papers published on journal focused on nutraceutical and human reproduction.\n\nEvidences: It is questionable if various molecules that are positively associated with higher Daporinad price oocyte competence, higher fertilization rate and embryo development could be supplemented to infertile patients with the aim to partly reduce the frequency of unsuccessful IVF.\n\nPerspectives: Aim of this short review is mainly to focus the attention on potentially positive effects in

female fertility of few, well established substances, that could be suggested as a dietary supplement.”

“PTR is a serious problem in patients being treated for hematologic disorders. Two patients with acute leukemia developed PTR after allogeneic BMT from one HLA-antigen-mismatched mother attributable to HLA antibodies, which could not be detected in their serum before BMT. HLA antibodies, whose specificity resembled that of each patient, were detected in each donor’s serum. Each

donor had probably been immunized during pregnancy by their partner’s HLA antigens expressed by the fetus, consequently, transplanted donor-derived cells provoked HLA antibodies in each recipient early after BMT, and those HLA antibodies induced PTR. If the mothers are selected as donors for their children, they should be tested for the presence of PKC412 in vivo HLA antibodies.”
“Introduction and objective: Toxoplasma gondii and Neospora caninum are two closely related cyst forming apicomplexean protozoa that infect a wide range of warm-blooded animals. N. caninum has similar morphologic and biologic characteristics to T. gondii and until 1988 was misdiagnosed as T. gondii. Tachyzoites and tissue cysts of both parasites are found intracellularly in the intermediate hosts. The aim of this study was to determine the seroprevalence rate of anti-Neospora caninum and anti-Toxoplasma gondii antibodies in feral cats (Felis catus) in Ahvaz, Iran.

Even so, in 2009, 78.9 percent of Hispanics had coverage, versus 96 percent of non-Hispanic whites. Language and other cultural factors remained significant barriers: Only 66.6 percent of Hispanics with limited proficiency in English were insured. One-third of Spanish-speaking Hispanics still did not have a personal

provider in 2009, and 26.8 percent reported not seeing a doctor because of cost, up from 18.9 percent in 2005. We suggest ways to reduce such disparities through national health care reform, including simplified enrollment and reenrollment processes and assistance in finding a provider and navigating an unfamiliar care system.”
“The purpose of this study was to determine the functional recovery of the transplanted induced pluripotent learn more stem cells in a rat model of Huntington’s disease with use of F-18-FDG microPET/CT imaging. Methods: In a quinolinic acid-induced

rat model of striatal degeneration, induced pluripotent stem cells were transplanted into the ipsilateral lateral ventricle ten days after the quinolinic acid injection. The response to the treatment was evaluated by serial F-18-FDG PET/CT scans and Morris water maze test. Histological analyses and Western blotting were performed six weeks after stem cell transplantation. Results: After induced pluripotent stem cells transplantation, higher F-18-FDG accumulation in the injured striatum was observed during the 4 to 6-weeks period compared JPH203 clinical trial with the quinolinic acid-injected group, suggesting the metabolic recovery of injured

striatum. The induced pluripotent stem cells transplantation improved learning and memory function (and striatal atrophy) of the rat in six week in the comparison with the quinolinic acid-treated controls. In addition, immunohistochemical analysis demonstrated that transplanted stem cells survived and migrated into the lesioned MDV3100 solubility dmso area in striatum, and most of the stem cells expressed protein markers of neurons and glial cells. Conclusion: Our findings show that induced pluripotent stem cells can survive, differentiate to functional neurons and improve partial striatal function and metabolism after implantation in a rat Huntington’s disease model.”
“A study was undertaken to identify the morphophysiological traits associated with water-logging tolerance in pigeonpea [Cajanus cajan L. (Millsp.)]. The formation of aerenchyma cells, lenticels, and adventitious roots in the tolerant genotypes were found to be associated with water-logging tolerance in pigeonpea. The tolerant genotypes, namely, ICP 5028, ICPH 2431, ICPL 87119, ICPH 2740, ICPL 149, ICPL 20241, and MAL15, exhibited varying responses to hypoxic conditions. Formation of aerenchymatous cells was common in all the water-logging tolerant genotypes. Besides this, five tolerant genotypes (ICP 5028, ICPH 2431, ICPL 87119, ICPH 2740 and MAL 15) developed lenticels, while ICPL 149 and ICPL 20241 formed prominent adventitious roots.

These results suggest that a clinically safe dose of VPA can enhance radiation-induced cytotoxicity in human ESCC cells by chromatin decondensation with histone hyperacetylation and downregulation of Rad51. In conclusion, VPA appears to be a safe and promising radiosensitizer for esophageal cancer radiotherapy.”
“Mitochondrial production of H2O2 is low with NAD substrates (glutamate/pyruvate, 3 and 2 mM) (G/P) and increases over ten times upon further addition of succinate, with the formation of a sigmoidal curve (semimaximal value

at 290 A mu M, maximal H2O2 production at 600 A mu M succinate). Malate counteracts rapidly the succinate induced increased H2O2 release and moves the succinate dependent H2O2 production curve to the right. Nitric oxide (NO) and carbon monoxide (CO) are cytochrome c oxidase inhibitors which increase mitochondrial ROS production. Cyanide (CN-) was used to mimic NO and CO. learn more In the presence of G/P and succinate (300 A mu M), CN- progressively increased the H2O2 release rate, starting at 1.5 A mu M. The succinate dependent H2O2 production curve was moved to the left by 30 A mu M CN-. The V-max was little

modified. We conclude that succinate is the controller of mitochondrial H2O2 production, modulated by malate and CN-. We propose that succinate promotes an interaction between Complex II and Complex I, which activates O (2) (-) production.”
“Recently, the plasticizer di-n-hexyl phthalate A-1210477 purchase (DnHP) has been demonstrated VRT752271 to be teratogenic and adversely affect the reproductive tract in male rat fetuses. This study was undertaken to determine the long-term effects of an in utero, exposure to DnHP on the reproductive development of the male offspring. Di-2-ethylhexyl phthalate (DEHP), another phthalate ester known to disrupt the androgen-dependent sexual differentiation in the male rat, was used as a positive control. Pregnant Sprague-Dawley

rats were administered DnHP or DEHP, by gavage on gestation Days 12-21, at doses of 0, 50, 125, 250, or 500 mg DnHP/kg-d and 500 mg DEHP/kg-d. DnHP had no significant effect on maternal body weight gain and pup weights during lactation. The proportion of live pups on postnatal day I was slightly, but not significantly, lower than control at 250 and 500 mg DnHP/kg-d. Male offspring displayed reduced anogenital distance on postnatal day 1 (PND) at 125 mg DnHP/kg-d and above, and areola/nipple retention before weaning and at adulthood at 250 and 500 mg DnHP/kg-d. At necropsy on PND 70-78 or PND 111-120, severe malformations of the reproductive tract were observed in young adult males at 125 mg DnHP/kg-d and higher doses. They mainly consisted of hypospadias, underdeveloped testis, and undescended testis. Additionally, histopathological examination revealed seminiferous tubule degeneration at the two high doses.

The maximum PEG-IFN effectiveness during the first PEG-IFN dose and the HCV-infected cell loss rate (delta), were significantly higher in SVRs compared to non-SVRs (median 95% vs. 86% [p = 0.013], 0.27 vs. 0.11 day(-1) [p = 0.006], respectively). Patients infected with HCV genotype 1 had a significantly lower average first-week PEG-IFN effectiveness (median 70% vs. 88% [p = 0.043]), however, 4- to 12-week PEG-IFN effectiveness was not significantly different compared to those with genotype 3 (p = 0.114). Genotype 1 had a significantly lower delta compared to

genotype 3 (median 0.14 vs. 0.23 day(-1) [p = 0.021]). The PEG-IFN concentration that decreased HCV production by 50% (EC(50)) was lower in genotype 3 compared to genotype 1 (median 1.3 vs. 3.4 [p = 0.034]).\n\nConclusions: Both the HCV-infected

cell loss rate (delta) and the maximum effectiveness of the first dose 3-deazaneplanocin A price of PEG-IFN-alpha-2a characterised HIV co-infected patients and were highly predictive of SVR. Further studies are needed to validate these viral kinetic parameters as early on-treatment prognosticators of response in patients with HCV and HIV.

“Study Design. Case report.\n\nObjective. To describe a novel technique to remove anterior instrumentation from a posterior approach while performing posterior-based osteotomies for spinal deformities.\n\nSummary of Background Data. Posterior-based osteotomies such as pedicle learn more subtraction osteotomies (PSOs) and vertebral column resections are performed to restore sagittal alignment. The removal of previously placed anterior implants PFTα clinical trial at the desired osteotomy level can often be challenging. We propose a technique for the removal of anterior instrumentation

through a posterior approach to facilitate osteotomy closure and deformity correction, while avoiding the need for an anterior incision.\n\nMethods. A 34-year-old woman presented with a residual deformity after several anterior and posterior procedures. The residual coronal Cobb angle measured 60 between T7 and L2, with a 46 thoracolumbar kyphosis between T10 and L2. The screw head at the desired osteotomy level was in close proximity to the liver after the previous right-sided thoracoabdominal approach. Therefore, the T11 anterior screw was accessed through a posterior costotransversectomy approach and disconnected from the rod proximally and distally with a high-speed side-cutting burr. A portion of the right lateral vertebral body of T11 was removed to expose the neck of the screw, which was separated from the shaft with the same burr. A PSO was performed at T11 and the remaining screw shank was removed with the posterior-based osteotomy.\n\nResults. No major complications were encountered during the procedure. The anterior screw at T11 was removed from posteriorly, and the PSO was completed successfully.

“The blp locus of a type 6A strain of Streptococcus pneumoniae encodes a two-peptide https://www.selleckchem.com/products/MLN-2238.html bacteriocin, pneumocin MN, which mediates intraspecies competition during mouse nasopharyngeal colonization. This locus is regulated by a quorum-sensing mechanism consisting of a dedicated two-component regulatory system and a peptide pheromone. Like most clinical isolates, this type 6A strain can be separated into opaque and transparent colony variants, each playing a different role during pneumococcal infection. In this study, we show that the blp locus is differentially regulated at the posttranscriptional level in pneumococcal opacity variants. Transparent and opaque variants produce equivalent amounts of blpMNPO

transcript when stimulated with a synthetic pheromone, but transparent variants have no pneumocin MN-mediated inhibitory activity while opaque variants produce large zones of inhibitory activity. The differential regulation in opacity variants is driven by the two-component regulatory system CiaRH via its regulation of the serine protease HtrA. Transparent mutants deficient in CiaH or HtrA show increased pneumocin MN-mediated inhibition. In addition, these mutants demonstrate alterations in their dose response to a synthetic Mizoribine solubility dmso peptide pheromone, suggesting that HtrA activity impacts pneumocin MN production

at the level of signaling. This, in addition to its known effects on competence, suggests that HtrA is a pleiotropic regulator whose protease activity affects several important bacterial pathways. The complex regulation of pneumocins may allow the pneumococcus to reserve the secretion of active peptides for situations where the

benefit of their inhibitory activity outweighs the cost of their production.”
“Zollinger-Ellison syndrome (ZES) is an endocrinopathy A-1210477 price characterized by gastrin-secreting tumors, responsible for causing the formation ofmultiple, refractory, and recurrent peptic ulcers in the distal duodenum and proximal jejunum. Two main variants have been described, sporadic and those found in association with parathyroid andpituitary tumors, a genetic disorder known asmultiple endocrine neoplasia-1 (MEN-1). Biochemical serum evaluation for elevated gastrin, followed by radiological or nuclear localization of the primary lesion, is mandated for establishing diagnosis. The mainstays of treatment include management of hypersecretory state withmedical suppression of gastric acid production and surgical resection of primary tumor for the prevention of malignant transformation and metastatic complications. Medical therapy with proton pump inhibitors has virtually eliminated the need for acid-reducing surgical procedures. Surgical approach to sporadic and MEN-1associated ZES varies based on our understanding of the natural history of the condition and the probability of cure; however, resection to a negative microscopic margin is indicated in both cases.

These tissues were chosen because they were target sites of carcinogens, and/or relevant to a specific route of exposure. Recently, there has been particular focus on the gastrointestinal

(GI) tract as it is a contact site associated with high exposure following oral gavage. Furthermore Epigenetic inhibitor GI tumors are observed with high frequency in human populations. A collaborative study of the rat glandular stomach and colon MNT was conducted in conjunction with a collaborative study of the repeated-dose liver MNT. Based on limited data currently available, the rodent MNT using the glandular stomach and/or colon seems to detect genotoxic carcinogens with GI tract target-organ specificity. find more The working group concluded that the GI tract MNT would be a promising method to examine clastogenicity or aneugenicity of test chemicals in the stomach and/or colon. Further data will be needed to fully establish the methods, and to identify the sensitivity and specificity of the GI tract MNT. (C) 2015 Elsevier B.V. All rights reserved.”
“Previous studies investigating the influence of gender on ST-segment elevation myocardial infarction have reported conflicting results. The aim of this study was to assess

the influence of gender on ischemic times and outcomes after ST-segment elevation myocardial infarction in patients treated with primary percutaneous coronary intervention in modern practice. The present multicenter registry included consecutive patients with ST-segment elevation myocardial infarctions treated with primary percutaneous coronary intervention at 3 hospitals. Adjusted mortality rates were calculated using Cox proportional-hazards ON-01910 analyses. In total, 3,483 patients were included, of whom 868 were women (25%). Women were older, had a higher risk factor burden, and more frequently had histories of malignancy. Men more often had cardiac histories and peripheral vascular disease. Ischemic times were longer in women (median 192 minutes [interquartile range 141 to 286] vs 175

minutes [interquartile range 128 to 279] in men, p = 0.002). However, multivariate linear regression showed that this was due to age and co-morbidity. All-cause mortality was higher at 7 days (6.0% in women vs 3.0% in men, p<0.001) and at 1 year (9.9% in women vs 6.6% in men, p = 0.001). After adjustment, female gender predicted 7 day all-cause mortality (hazard ratio 1.61, 95% confidence interval 1.06 to 2.46) and cardiac mortality (hazard ratio 1.58, 95% confidence interval 1.03 to 2.42) but not 1-year mortality. Moreover, gender was an independent effect modifier for cardiogenic shock, leading to substantially worse outcomes in women. In conclusion, ischemic times remain longer in women because of age and comorbidity.

Plasma concentrations of L-arginine are decreased after

trauma or surgery but have been variably reported to be normal or decreased in patients with sepsis.\n\nMethods: We searched MEDLINE and Embase from database inception until January 2010 for the MESH terms “arginine,” ” amino acids,” and “sepsis” and reviewed all studies that reported plasma arginine concentrations in humans with sepsis. Studies were grouped according to the presence or absence of trauma and surgery. We performed a pooled quantitative analysis on the subset of studies that reported appropriate data.\n\nResults: We identified 285 citations, of which 16 met inclusion criteria and 10 were included in the quantitative analysis. Plasma arginine concentration was lower CA3 cell line in sepsis patients compared with concurrent or historical controls in three of four studies of surgical sepsis, one of four of sepsis after trauma,

and all eight studies of predominantly medical sepsis. In the quantitative analysis, mean plasma L-arginine concentration was 33.9 mu mol/L (95% confidence interval, 41.2-26.6) lower in sepsis patients than in concurrent nonseptic controls (p<.001), which is a relative decrease of 41%.\n\nConclusion: Plasma concentrations of plasma L-arginine are substantially decreased in patients with sepsis in the absence of trauma or surgery. There are not enough studies of sufficient quality to determine whether this is also the case for trauma-associated or surgery-associated sepsis. (Crit Care Med 2011; 39:380-385)”
“Raman and SERS spectra of homodipeptide Gly-Gly and Gly were recorded and compared in this paper, and band assignment for the NVP-LDE225 functional groups contained in these molecules was analyzed in detail. Time-dependent and pH-dependent SERS spectra of Gly-Gly molecule adsorbed on nano-colloidal silver surface buy VX-809 were also studied. The time-dependent SERS spectra of Gly-Gly are characterized by the increase in intensity of bands primarily representing the vibrational signatures emanating from

the amino and amide moiety of Gly-Gly molecule. Iris found that the adsorption style of Gly-Gly on the silver colloid changes as time goes on; at 5 min after adding the sample to the silver colloid, Gly-Gly adsorbs on silver surface firstly through the carboxylate, amino and amide groups, and then the carboxylate group is far away from the silver surface at 10 min to 3 days. The SERS variation of Gly-Gly with the change of pH suggests that the adsorption style is pH-dependent, the different adsorption behavior of the Gly-Gly occurs on silver surface at different pH values.
