Collectively, our BRIT1-null mouse model demonstrates DAPT purchase that BRIT1 is essential for maintaining genomic stability in vivo to protect the hosts from both programmed and irradiation-induced DNA damages, and its depletion causes a failure in both mitotic and meiotic recombination DNA repair via impairing RAD51/BRCA2′s function and as a result leads to infertility and genomic instability in mice.”
“The purpose of this study was to evaluate human hair follicle melanogenic activity using
the [C-14]-2-thiouracil, which was known to incorporate into nascent melanins. Results obtained on pigmented, grey and non-pigmented hair follicles demonstrated that [C-14]-2-TU incorporation was restricted to the melanogenic compartment with a strong accumulation located around dermal papilla and within the fibre of pigmented hair follicles. Quantitative analysis of [C-14]-2-TU incorporation showed a significant increase in pigmented hair follicles upon stimulation with 1 mu m forskolin
concomitant to an increase in tyrosinase levels. A strong significant decrease in [C-14]-2-TU incorporation was noted, when hair follicles were incubated with the tyrosinase competitive inhibitor kojic acid (200 mu m). Incubation with the MC1-R agonist alpha-MSH (0.2 mu m) did not induce a significant stimulation of hair melanogenesis. The present buy GDC-0973 model could thus represent a useful new tool to identify modulators of human hair pigmentation.”
“Recent advances in -omics technologies such as transcriptomics, metabolomics, and proteomics along with genotypic profiling have permitted dissection of the genetics of complex traits represented by molecular phenotypes in nonmodel
species. To identify the genetic factors underlying variation in primary metabolism in potato (Solanum tuberosum), we have profiled primary metabolite BAY 73-4506 Protein Tyrosine Kinase inhibitor content in a diploid potato mapping population, derived from crosses between S. tuberosum and wild relatives, using gas chromatography-time of flight-mass spectrometry. In total, 139 polar metabolites were detected, of which we identified metabolite quantitative trait loci for approximately 72% of the detected compounds. In order to obtain an insight into the relationships between metabolic traits and classical phenotypic traits, we also analyzed statistical associations between them. The combined analysis of genetic information through quantitative trait locus coincidence and the application of statistical learning methods provide information on putative indicators associated with the alterations in metabolic networks that affect complex phenotypic traits.”

CONCLUSIONS: High-quality training, strict compliance with evidence-based CYT387 mouse guidelines, and thorough documentation is associated with significant reductions in CLABSIs. Mindful organizing may lead to a better understanding of what goes into a unit’s ability to handle peak demands and sustain extraordinary
performance in the long-term.”
“A rice tiller is a specialized grain-bearing branch that contributes greatly to grain yield. The MONOCULM 1 (MOC1) gene is the first identified key regulator controlling rice tiller number; however, the underlying mechanism remains to be elucidated. Here we report a novel rice gene, Tillering and Dwarf 1 (TAD1), which encodes a co-activator of the anaphase-promoting complex (APC/C), a multi-subunit E3 ligase. this website Although the elucidation of co-activators and individual subunits of plant APC/C involved in regulating plant development have emerged recently, the understanding of whether and how this large cell-cycle machinery controls plant development is still very limited. Our study demonstrates that TAD1 interacts with MOC1, forms a complex with OsAPC10 and functions as a co-activator of APC/C to target MOC1 for degradation in a cell-cycle-dependent manner. Our findings uncovered a new mechanism underlying shoot branching and shed light on the understanding of how the cell-cycle machinery
regulates plant architecture.”
“Background. In patients with cirrhosis excessive hemorrhage and the need for blood transfusion are associated with increased postoperative morbidity and mortality as well as a poor long-term outcome. Saline-linked radiofrequency dissecting sealer (TissueLink) is a recent advance in technology that improves hemostasis during difficult liver resections. Preliminary studies have shown that this technique reduces blood loss without inflow occlusion.\n\nPatients and methods. A controlled study
was performed on 122 consecutive patients with cirrhosis who underwent liver resection for hepatocytotic carcinoma. The outcomes of liver transection with clamp crushing and TissueLink were compared to evaluate which strategy is most beneficial to the patients.\n\nResults. Both intraoperative blood loss and blood transfusion requirements CP-868596 Protein Tyrosine Kinase inhibitor were significantly higher in the crushing clamp group than in the TissueLink group (P = 0.047 and P = 0.031, respectively). In addition, a significantly higher number of patients required a blood transfusion in the crushing clamp group (P < 0.001). However, the transection time was significantly faster in the crushing clamp group than in the TissueLink group (P < 0.001). The number of patients that required Pringle’s maneuver was markedly higher in the crushing clamp group (P < 0.001). In addition, the hemostasis time was significantly longer in the crushing clamp group (P < 0.001).
In the response extinction condition, rats performed a runway approach response to an empty fluid well. In the latent extinction condition, rats were placed at the empty fluid well without performing a runway approach response. Rats trained with the sucrose solution displayed normal extinction behavior in both conditions. In contrast, rats trained with the
cocaine solution showed normal response extinction but impaired latent extinction. The selective impairment of latent extinction indicates that oral cocaine self-administration alters the relative effectiveness find more of multiple memory systems during subsequent extinction training.”
“Objective: To investigate the association of bacterial pneumonia and respiratory failure in children with community-acquired influenza infection presenting to a pediatric intensive care unit.\n\nDesign: Retrospective cohort study.\n\nSetting: Pediatric intensive care unit at an urban academic Fosbretabulin nmr tertiary-care children’s hospital.\n\nPatients: All patients aged <18 yrs admitted to our pediatric intensive care unit with laboratory-confirmed
influenza infection between October 2002 and September 2008.\n\nInterventions: All patients who met our clinical definitions of respiratory failure and bacterial pneumonia were identified. Patients were stratified by presence or absence of chronic medical conditions associated with an increased risk of influenza-related complications.\n\nMeasurements Compound C in vitro and Main Results: There were 59 patients admitted to the pediatric intensive care unit with laboratory-con-firmed community-acquired influenza during the period of study. Twenty-four patients
(41%) had respiratory failure and 14 patients (24%) met the definition of bacterial pneumonia. The risk of respiratory failure was increased in the presence of bacterial pneumonia (p = .04). Adjusting for age and chronic medical conditions, patients with bacterial pneumonia had a 3.7 times greater odds (p = .04) of respiratory failure.\n\nConclusions: Our findings suggest that bacterial pneumonia was associated with increased odds of respiratory failure in both previously healthy children and those with chronic medical conditions. Early aggressive therapy should be considered for patients with severe influenza. (Pediatr Crit Care Med 2011; 12:e181-e183)”
“Bee stings of the eye are uncommon entities and ocular reactions to the bee venom are wide, ranging from mild conjunctivitis to sudden vision loss. We present the case of a patient who suffered a bee sting of the cornea and the response to the poison components. We go through the bee venom properties, its actual treatment, and propose a new management alternative.
Key questions that need to be addressed include how this system assembles in the cell envelope and the mechanism by which it translocates effector proteins across two membranes, the identification of such effectors and their function, how this secretion system contributes to virulence, interbacterial interactions and/or adaptation to the environment, and the evolutionary relationship between T6SS machine and bacteriophage T4. Focused on how the proteins constituting the secretion system interact, we recently identified a sub-complex of the T6SS comprised of four cell envelope proteins: the inner membraneanchored TssL, TssM and TagL PD-1/PD-L1 Inhibitor 3 proteins and the outer membrane-associated
TssJ lipoprotein. We further demonstrated that the TagL subunit carries a specific domain allowing anchorage of the secretion system to the peptidoglycan (PG) layer. Herein, we discuss these results, examine whether PG-binding motifs are found within other T6SS subunits and express hypotheses
regarding the role of PG-binding motifs in type VI secretion.”
“Twenty hair (Pelibuey x Katadin x BlackBelly) and 20 wool (Rambouillet x Criollo) lambs were fattened in an intensive feeding system to reach 40kg body weight at ten months of age. The yield of lamb sides and back fat (51.9%, 2.5mm vs. 47.0%, 2.3mm) were greater in Rabusertib purchase wool lambs. Meat pH was not different between phenotypes but meat temperature was higher during the first hours postmortem in wool lamb sides (27, 23, and 20, vs. 24, 20, and 17 degrees C). Protein content in meat from the neck (braquicephalic and esternocephalic muscles) and loin (Longissimus lumborum
muscle) were higher in hair lambs (21.1 and 20.4 vs. 19.7 and 19.3%), while moisture of the same muscles was higher in wool lambs (75.6 and 75.9 vs. 73.6 and 74.3%). Ash content was similar in both phenotypes, but palmitoleic acid was greater Panobinostat cost in hair lambs (2.9 and 2.7 vs. 2.7 and 2.5%). In fresh meat, pH, meat toughness, and water activity (Wa) of loin did not differ; but water holding capacity (WHC) was higher in hair lambs, and the same response was observed for cooked meat toughness from the neck, and in raw and cooked meat from loin. There were differences in the colour of meat from the neck, having values for L*, b* and tonalities greater in wool lambs, and a* greater for hair lambs. Sensorial parameters were similar in both phenotypes.”
“In this paper, an implicitly implemented high order large eddy simulation by using the fifth order bandwidth-optimized WENO scheme is applied to make comprehensive studies on ramp flows with and without control at Mach 2.5 and Re-0 = 5760. Flow control in the form of microramp vortex generators (MVG) is applied. The mechanism of vortex ring generation behind MVG has been studied in detail and shear layer instability has been studied and found as the mechanism of K-H vortex ring generation.
ANXA1 expression in the gut mucosa was measured by IHC. Plasma ANXA1 levels were measured by ELISA.\n\nResults: We found that the reduction in ANXA1 protein levels in plasma coincided with a decrease in the ANXA1 mRNA expression in peripheral blood of IBD patients. ANXA1 expression is upregulated during IFX therapy in patients with a successful intervention but not in clinical non-responders. The IFX therapy also modified GANT61 order the cellular immune activation in the peripheral blood of IBD patients. Decreased expression of ANXA1 was detected in
the colonic mucosa of IBD patients with incomplete resolution of inflammation during continuous therapy, which correlated with increased levels of TNF-alpha transcripts. Gut mucosal epithelial barrier disruption was evident by increased plasma bacterial 16S levels.\n\nConclusion: Loss of ANXA1 expression may support
inflammation during IBD and can serve as a biomarker of disease progression. Changes in ANXA1 levels may be predictive of therapeutic efficacy.”
“Deafness is the most Selleckchem Ulixertinib common sensory disorder in humans and the aetiology of genetic deafness is complex. Mouse mutants have been crucial in identifying genes involved in hearing. However, many deafness genes remain unidentified. Using N-ethyl N-nitrosourea (ENU) mutagenesis to generate new mouse models of deafness, we identified a novel semi-dominant mouse mutant, Cloth-ears (Clth). Cloth-ears mice show reduced acoustic startle response and mild hearing loss from similar to 30 days old. Auditory-evoked brainstem buy GM6001 response (ABR) and distortion product otoacoustic emission (DPOAE) analyses indicate that the peripheral neural auditory pathway is impaired in Cloth-ears mice, but that cochlear function is normal. In addition, both Clth/Clth and Clth/+ mice display paroxysmal tremor episodes with behavioural arrest. Clth/Clth mice also show a milder continuous tremor during movement and rest. Longitudinal phenotypic analysis showed
that Clth/+ and Clth/Clth mice also have complex defects in behaviour, growth, neurological and motor function. Positional cloning of Cloth-ears identified a point mutation in the neuronal voltage-gated sodium channel alpha-subunit gene, Scn8a, causing an aspartic acid to valine (D981V) change six amino acids downstream of the sixth transmembrane segment of the second domain (D2S6). Complementation testing with a known Scn8a mouse mutant confirmed that this mutation is responsible for the Cloth-ears phenotype. Our findings suggest a novel role for Scn8a in peripheral neural hearing loss and paroxysmal motor dysfunction.”
“The epidemic of Clostridium difficile infection fueled by new virulent strains of the organism has led to increased use of fecal microbiota transplantation (FMT). The procedure is effective for even the most desperate cases after failure of multiple courses of antibiotics.
Our aim was to determine the association between elevated fibrinogen and decreased high-density lipoprotein cholesterol (HDL-C) levels with https://www.selleckchem.com/products/ro-3306.html recurrent CVT. Methods: This retrospective cohort study included participants if they had a first episode of objectively defined CVT and were admitted to Xuan Wu Hospital, Capital Medical University from August 2005 to September 2009. Demographic and clinical variables were collected, as well as laboratory parameters, including plasma fibrinogen and HDL-C. Patients with CVT were followed
for recurrent symptomatic CVT. Follow-up was through the end of September 2010. Potential predictors of recurrence were analyzed using Cox survival analysis. Results: At the end of the follow-up, 95 patients were eligible for the study. Twelve of 95 patients (12.6%) had
recurred CVT. The median time of recurrence was 7 months (range: 1-39 months). Eight of these 12 (66.7%) experienced recurrence within the first 12 months after their initial CVT. The recurrence rate of CVT was 2.76 per 100 patient-years. Multivariate Cox regression analysis demonstrated that the coexistence of high fibrinogen ( bigger than 4.00 g/L) and low HDL-C ( smaller than 1.08 mmol/L) levels at baseline was the only independent predictor for recurrent CVT (hazard ratio: 4.69; 95% confidence interval: 1.10-20.11; P smaller than 0.05). Of the twelve patients with recurrent CVT in our study, 7 (58.3%) had high fibrinogen plus low HDL-C levels. All 7 of these patients took check details warfarin for 3-12 months, and 6 of 7 had recurrent CVT after the discontinuation of anticoagulant p38 MAPK activity treatment. Conclusions: Concomitant high fibrinogen and low HDL-C levels may be associated with recurrence of CVT. The effect of potential risk factors related to atherothrombosis on recurrent CVT should be closely monitored.”
“Objectives There have been few reports regarding olanzapine (OLZ)-related QT prolongation and hyperprolactinemia. This study evaluated the
dose-dependent effect of OLZ on QT interval and plasma prolactin (PRL) level in a single sample of patients with schizophrenia.\n\nMethods Twenty-six subjects treated with varying starting doses of OLZ were enrolled in the study. Following baseline assessments, which included completion of the Brief Psychiatric Rating Scale (BPRS), measurements of Body Mass Index (BMI), QT interval, electrolytes, fasting plasma glucose, PRL, hemoglobin A1c (HbA1c), total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), and low density lipoprotein (LDL), the dose of OLZ was increased for each subject. The same parameters were evaluated following the increased dose treatment.\n\nResults A significant decrease was observed in BPRS score (p=0.01) following treatment with an increased dose of OLZ. Significant increases were observed in BMI (p=0.032), QTc (p=0.031), and plasma PRL level (p=0.028).

“Objective: To determine whether blood glucose values of over 200 mg/dL in the oral glucose tolerance test (OGTT) are associated with pregnancy complications and adverse perinatal outcomes in patients with gestational diabetes mellitus (GDM).\n\nMethods: A retrospective cohort study was performed comparing patients with GDM A1 (diet controlled) that had at least one value of 200 mg/dL or higher in the OGTT, to those who did not. Patients were treated at the diabetes day care clinic of a tertiary medical center
between the years 1999 and 2010. Data were available from the computerized perinatal databases.\n\nResults: During the study period, 778 women with GDM were treated at the diabetes day care clinic. Of these, 162 had at least one test value of 200 mg/dL or greater. No significant differences regarding maternal and perinatal complications, such as polyhydramnios, macrosomia (birth-weight above 4 kg), shoulder dystocia, low Apgar scores at 5 min (<7) and cesarean section ASP2215 inhibitor were noted between
the groups.\n\nConclusions: A value of 200 mg/dL or more in the OGTT is not an indicator of perinatal complications.”
“Objectives: Collapse of the upper lateral cartilage (ULC) is associated with narrowing of the internal nasal valve (INV). The goal of this article is to describe a novel procedure that repositions the ULC, opening the INV,
without implants, grafts, or permanent sutures.\n\nMethods: Before-and-after digital photographs of patients with ULC and INV collapse who underwent endonasal ULC repositioning were PCI-32765 Angiogenesis inhibitor analyzed. The surgical procedure consists of an intercartilaginous incision and the creation of a surface that permits scarification upon cartilage reapproximation. Precise placement of a support apparatus permits the ULC to heal into a position in direct contact with the lower lateral cartilage, thus dilating the INV. The percentage of collapse of the ULC (PCULC), determined by ULC shape measurements made with computer-aided design software, was compared on before-and-after photographs by use of Student’s t-test (paired).\n\nResults: The study included 52 patients (79 procedures) followed for 1 to 18 months after surgery in the period 2007 to 2009. There were no complications or revision surgeries. The preoperative mean PCULC was 58.6%. The postoperative mean PCULC was 5.7% (p <0.0001).\n\nConclusions: Repair of the INV via ULC repositioning is a simple, relatively safe procedure that produces a statistically significant improvement in the PCULC. The functional change at the INV may be inferred from the ULC shape, but further prospective clinical studies are required.
6, 1.7 and 1.3 mu m particles were exclusively employed. A fast baseline separation of loratadine and related impurities (R-s,R-min = 2.49) was achieved under the best analytical conditions (i.e. column of 50 mm x 2.1 mm, 1.3 mu m, 10-90% ACN in 5 min, T = 40 degrees C, pH =3, F=0.5 ml/min). This optimal method was successfully tested on columns packed with other particle sizes, namely 1.7 and 2.6 pm, to reduce pressure
drop. The selectivities and retentions remained identical, while LY2090314 the peak widths were logically wider, leading to a reduction of peak capacity from 203 to 181 and 159 on the 1.3, 1.7 and 2.6 mu m particles, respectively. On the minimum, the resolution was equal to 1.54 on the 50 mm x 2.1 min, 2.6 pm stationary phase. Next to this, the method was transferred to columns of different lengths, inner diameters and particle sizes (100 mm x 3 mm, 2.6 mu m or 150 mm x 4.6 mm, 5 pm). These columns were used on other LC instruments possessing larger dwell volumes. The modelling software employed for developing Vorinostat concentration the original method was able to calculate the new gradient conditions to be used. The accuracy of prediction was excellent, as the average retention time errors between predicted and observed chromatograms were -0.11% and 0.45% when transferring the method
to 100 mm x 3 mm and 150 mm x 4.6 mm columns, respectively. This work proves the usefulness and validity of HPLC modelling software for transferring methods between different instruments, column dimensions and/or flow rates. (c) 2014 Elsevier B.V. All rights reserved.”
“Alveolar LY3039478 purchase formation is coupled
to the spatiotemporally regulated differentiation of alveolar myofibroblasts (AMYFs), which contribute to the morphological changes of interalveolar walls. Although the Ras-ERK signaling pathway is one of the key regulators for alveolar formation in developing lungs, the intrinsic molecular and cellular mechanisms underlying its role remain largely unknown. By analyzing the Ras-ERK signaling pathway during postnatal development of lungs, we have identified a critical role of DA-Raf1 (DA-Raf)-a dominant-negative antagonist for the Ras-ERK signaling pathway-in alveolar formation. DA-Raf-deficient mice displayed alveolar dysgenesis as a result of the blockade of AMYF differentiation. DA-Raf is predominantly expressed in type 2 alveolar epithelial cells (AEC2s) in developing lungs, and DA-Raf-dependent MEK1/2 inhibition in AEC2s suppresses expression of tissue inhibitor of matalloprotienase 4 (TIMP4), which prevents a subsequent proteolytic cascade matrix metalloproteinase (MMP) 14-MMP2. Furthermore, MMP14-MMP2 proteolytic cascade regulates AMYF differentiation and alveolar formation. Therefore, DA-Raf-dependent inhibition of the Ras-ERK signaling pathway in AEC2s is required for alveolar formation via triggering MMP2 activation followed by AMYF differentiation.
22.29 +/- 2.21 mm, p smaller than 0.001), which represented an absolute and percent decrease in stent dimension of 1.10 +/- 0.40 mm and 4.70 +/- 1.76%, respectively. In the multivariate analysis, the predictors of larger recoil
were a higher prosthesis/annulus ratio (r(2)=0.0624, p=0.015) and the SAPIEN XT prosthesis (r(2)=0.1276, p=0.001). No significant changes in haemodynamic performance were observed at discharge and follow-up in patients with larger recoil. Conclusions: TAVI with a balloon-expandable valve was systematically associated with a certain degree of valve stent recoil after balloon deflation. https://www.selleckchem.com/products/Erlotinib-Hydrochloride.html A higher degree of valve oversizing and the SAPIEN XT prosthesis predicted a larger degree of stent recoil.”
“A novel phosphorylation Selleck GDC0068 motif for casein kinase 1 (CK1) in response to two sulfated lipids [sulfatide and cholesterol-3-sulfate (SCS)] was determined, using three functional proteins [myelin basic protein (MBP), tau protein (TP) and RhoA (a small GTPase)] and five
synthetic NIBP peptides as phosphate acceptors for the kinase in vitro. It was found that (i) MBP, p8 (positions 38-118) cleaved from MBP, and a synthetic peptide M103 were effectively phosphorylated, by CK1 delta in the presence of SCS; (ii) sulfatide in comparison with CH-3S highly enhanced autophosphorylation of CK1 delta; (iii) SCS had a high binding affinity with NIBP and peptide M103, but not other MBP peptides lacking K-G-R; and (iv) a novel consensus phosphorylation motif (K/R-X-K/R-X-X-S/T)
for CK1 was identified among several SCS-binding proteins (SCS-BPs) and three CK1 isoforms (delta, Selleck AZD9291 epsilon and gamma). The binding of SCS to two basic brain proteins (MBP and TP) resulted in the high stimulation of their phosphorylation by three CK1 isoforms (c 6 and 6), but not CK1 gamma. In contrast, an acidic protein (RhoA) was effectively phosphorylated by CK1 delta in the presence of SCS, and also highly phosphorylated by CK1 gamma in the presence of sulfatide. Our results presented here suggest that (i) sulfatide may function as an effective stimulator for autophosphorylation of CK1; and (ii) cellular SCS-binding proteins, containing novel phosphorylation motifs for CK1, may be preferentially phosphorylated by CK1 with isoform specificity at the highly accumulated level of SCS in the brain.”
“Objectives: To determine the patterns and proximity of reflux events in patients with adult-onset asthma (AOA) using hypopharyngeal multichannel intraluminal impedance (HMII) and to assess outcomes of antireflux surgery (ARS) in patients with AOA.\n\nDesign: Retrospective review of prospectively collected data.\n\nSetting: University hospital.\n\nPatients, Interventions, and Outcomes: All patients with AOA referred to our testing center underwent HMII, and those with abnormal proximal exposure, defined as laryngopharyngeal reflux at least once a day and/or high esophageal reflux at least 5 times a day, subsequently underwent ARS.
We determined the therapeutic efficacies [clinical (CR) and pathological complete responses (pCR)] and changes in the proportion of positive cells for each biomarker pre- to post-neoadjuvant chemotherapy for each treatment regimen. Clinical-CR and quasi-pCR rates defined as the absence of invasive tumors or only a few remaining invasive tumor cells were 6.9 and 31.0% in the CT group and 46.2 and 65.4% in the CT+T group, respectively. In the CT group, the proportion of estrogen receptor (ER)-/progesterone receptor (PgR)-positive cells decreased significantly following treatment
(ER, 73.5 vs. 50.9%; P=0.02). Changes :in the proportion of ER-/PgR-positive cells were not noted in the CT+T group (ER, 81.9 vs. 80.3%; P=0.61), although a relatively greater decrease in the proportion of Ki-67-positive cells was found in the CT+T group than that in the click here CT group (-26.5 vs. -13.7%). These findings indicate that CT+T inhibits ER-negative and Ki-67-positive breast cancer cells. In conclusion, trastuzumab sensitized ER-negative proliferative cells to cytotoxic chemotherapy. This finding
may indicate an additional clinical effect of trastuzumab when administered in combination with conventional chemotherapy as neoadjuvant chemotherapy for HER2-positive breast cancer.”
“We describe a novel technique for placement Compound Library ic50 of an Amplatzer Vascular Plug I in a relatively short space. A mesenteric, relatively large-caliber, iatrogenic, high-flow arteriovenous fistula associated with a pseudoaneurysm was successfully closed using a single vascular plug. The “stuffing technique” allowed us to place a second plug within a very limited residual fistula tract, avoiding the plug
extending parent vessels.”
“Neutron reflectometry measurements show that lamellar structures composed of thin alternating water-rich and Nafion-rich layers exist at the interface between SiO(2) and the hydrated Nafion film. Lamellae thickness and number of layers increase with humidity. Selleck Napabucasin Some lamellae remain in the film after dehydration. Multilayer lamellae are not observed for Nafion on Au or Pt surfaces. Instead, a thin partially hydrated single interfacial layer occurs and decreases in thickness to a few angstroms as humidity is reduced to zero. The absorption isotherm of the rest of the Nafion film is similar to that of bulk Nafion for all three surfaces investigated. The observed interfacial structures have implications for the performance, reliability. and improvements of fuel cell proton exchange membranes and membrane electrode assemblies.”
