32 Patients with MHE also had impaired navigation skills.33 Navigation, required for safe driving, is a complex process that depends on functioning working memory, attention, and speed of mental processing; impairment in navigation skills correlated with impairment in response inhibition and attention. Although some data are available for HE, the economic burden associated with MHE has not been assessed.1 In the USA in 2003, estimated total charges for hospitalizations related to HE were over $US930m. Total charges for unspecified encephalopathy, portal hypertension, and alcoholic and non-alcoholic KPT-330 in vivo cirrhosis were approximately

Angiogenesis chemical $US268m, $US90m and $US3.3bn, respectively.1 The impact of MHE on daily life is enormous; half of the patients with MHE do not have regular employment, compared to 15% of patients without MHE.14 Blue-collar workers with liver cirrhosis and MHE are less likely to earn their wages than white-collar workers with MHE; 60% of ‘blue collar’ workers were unfit to work compared with 20% of ‘white collar’ workers.24 Diminished work performance and lost wages also entail substantial costs.

Socioeconomic implications of the profound negative effects of MHE on functioning in the workplace are significant. 9 MHE adversely affects HRQOL. (1b) The diagnosis of MHE rests on: (i) the presence of a disease that can cause MHE, such as, cirrhosis and/or the presence of a portal-systemic shunt (Table 1); (ii) normal mental status on clinical examination; (iii) demonstration of abnormalities of cognition and/or neurophysiological variables; and (iv) exclusion of concomitant neurological disorders. HE is traditionally classified into four grades

according to the West Haven criteria (Table 2).1,2 However, assignment of patients with cirrhosis to HE stages PAK5 0–2 relies strongly on the subjective impression of a physician, which does not invalidate the scale in individual cases, but may cause discrepancies between different observers and affect the results of multicenter trials. Reliability of the West Haven scale can be improved by combining it with the Mini-Mental State Examination (MMSE).34 The MMSE assesses mental status systematically and thoroughly in only 5–10 min. It is an 11-question measure that tests five areas of cognitive function: orientation, registration, attention and calculation, recall and language.34 The maximum score on MMSE is 30; a score of 23 or lower is indicative of cognitive impairment and clinically overt HE. All high-quality studies on MHE included MMSE as a screening test before administering diagnostic tests for MHE.3,21,22,31–33 13 HE should be graded according to West Haven criteria.

1 MCP-1 plays an important Ibrutinib molecular weight role in the induction of proinflammatory cytokines at the site of tissue injury.10 Here, we investigated

the effect of MCP-1 deficiency on alcohol-induced expression of cytokines in the liver. We elucidated the expression of circulating endotoxin (baseline)-mediated induction of proinflammatory cytokines TNFα, IL-1β, and IL-6, as well as CC-chemokine mRNA levels in liver of alcohol-fed WT and MCP-1KO mice. Here, we show that TNFα, IL-1β, and IL-6 mRNA was increased significantly in alcohol-fed WT mice, compared to pair-fed WT controls, whereas alcohol-fed MCP-1KO mice were unable to induce proinflammatory cytokine mRNA in the liver (Fig. 3A). MCP-1 deficiency also prevented chronic alcohol-induced liver tissue TNFα, as compared to WT mice (Fig. 3B). Interestingly, among CC-chemokine genes, KC/IL-8 INCB024360 in vivo mRNA was significantly decreased, but CCL4/MIP-1β and CCL5/RANTES mRNA was high in alcohol-fed MCP-1KO mice, compared to pair-fed controls (Fig. 3C). Furthermore, investigation of MCP-1-mediated adhesion molecules and macrophage markers demonstrated a significant induction of intercellular adhesion molecule 1 (ICAM-1) and cluster of differentiation (CD)68, but unchanged vascular cell adhesion molecule 1 (VCAM-1) and F4/80 in livers of alcohol-fed WT, but not MCP-1KO, mice (Fig. 3D). Because nuclear factor kappa light-chain enhancer of activated B cells (NF-κB) is important in chronic alcohol-mediated proinflammatory

cytokine production and macrophage activation,15 we next determined whether the inhibition of inflammatory cytokines was regulated by the lack of NF-κB activation in MCP-1-deficient mice. Interestingly, our results show that NF-κB binding activity in whole livers was significantly increased in alcohol-fed MCP-1-deficient mice (Fig. 3E), compared to alcohol-fed WT and pair-fed MCP-1KO mice. Furthermore, increased NF-κB activation

was observed in isolated KCs of alcohol-fed MCP-1KO and WT mice, compared to pair-fed controls (Fig. 3F). Immunohistochemical analysis revealed Metalloexopeptidase NF-κB p65 staining in nonparenchymal cells of alcohol-fed WT and MCP-1KO mice (Supporting Fig. 3). On the other hand, isolated hepatocytes showed decreased NF-κB activation in alcohol-fed WT mice, compared to pair-fed controls, and this inhibition was prevented in alcohol-fed MCP-1KO mice (Fig. 3F), likely contributing to NF-κB-mediated hepatocyte survival in alcohol-fed MCP-1KO mice. These results indicate that liver proinflammatory cytokine mRNA, ICAM-1, and CD68 are significantly decreased in chronic alcohol-fed MCP-1KO mice, compared to their WT counterparts, in an NFκB-independent manner. The classical feature of alcoholic liver injury is alcohol-mediated oxidative stress and increased sensitization to LPS, resulting in enhanced proinflammatory cytokine expression in the liver.1, 16 To further test the effect of sensitization to LPS in chronic alcohol-fed MCP-1-deficient mice, an in vivo LPS challenge (0.

An important phenotypic change in cadherin switching is the loss of ECAD expression. The loss of ECAD causes cells to dissociate from their neighbors and results in a loss of cell polarity. This, in turn, leads to the activation of cell signaling pathways that regulate the mesenchymal transition. On the contrary, an increase in ECAD expression inhibits cell transformation and tumor cell invasion in an adhesion-independent manner.3, 4 Myofibroblasts play a key role in wound healing and pathological organ remodeling.5 The most accepted myofibroblast progenitors in the liver are hepatic stellate cells (HSCs),5, 6 although various

other resident cells are recognized as sources of liver myofibroblasts.5 PF-02341066 chemical structure As HSCs activate, the level of ECAD expression decreases.7 Activated HSCs then promote the synthesis and deposition of the extracellular matrix (ECM) component and the induction of α-smooth muscle actin (αSMA). In addition, multiple signaling cascades accelerate the growth of activated HSCs6 and contribute to the development of liver fibrosis. Although the link between cadherin switching and the EMT process in HSCs has been studied,7, 8 it is yet unclear whether ECAD affects the activation of HSCs. Moreover, the potential

signaling Selleck PS341 and molecular regulatory mechanism by which ECAD antagonizes profibrogenic gene expression in quiescent HSCs has not been explored. Several lines of evidence indicate Suplatast tosilate that transforming growth factor β1 (TGFβ1) from autocrine or paracrine sources plays a role in activating HSCs and increasing the synthesis of ECM proteins and cellular receptors for various matrix proteins.6

TGFβ1 is regulated transcriptionally by transcription factors and posttranslationally by the maturation of the precursors.6 In response to TGFβ1, type I and II TGFβ1 receptors form a complex and induce receptor autophosphorylation. TGFβ1 is also known as a cytokine that induces EMT, which inhibits ECAD expression by up-regulating transcriptional repressors such as Snail, Zeb, and Twist.9 Activated TGFβ1 receptors transmit the signal by which regulatory Smad molecules (Smad3/2) are phosphorylated and form an active complex with co-Smad (Smad4). The transcription factor complex then moves to the nucleus, in which it promotes the transcription of target genes through interactions with specific Smad binding elements (SBEs; also called the CAGA box).10 It has been reported that single or multiple copies of SBEs are located in the upstream regions of TGFβ1′s target genes, such as plasminogen activator inhibitor 1 (PAI-1), matrix metalloproteinases (MMPs), and collagen type I.11, 12 Despite the finding that TGFβ1 leads to HSC activation with a phenotypic change of ECAD loss and causes hepatic ECM accumulation, it has not yet been determined whether ECAD overexpression inhibits the expression of TGFβ1 and its downstream target genes.

1% and the undetectable rate of HBV DNA (by real-time polymerase chain reaction) was 90.1%. The changes of total bilirubin, albumin, platelet count, MELD score, and CP score between the two time points were from 2.1 ±3.2 to 1.3±1.0 mg/dL (p=0.014), from 3.6±0.6 to 4.1±0.5 g/dL (p<0.001), from 102±44 to 110±48xl000>/mm3 (p=0.013), from Mitomycin C 9.2±5.2 to 6.7±5.2 (p<0.001), and from 6.4±1.8 to 5.5±1.0 (p<0.001), respectively. The distribution of CP class at baseline was 66.7% in A, 26.1% in B, and 7.2% in C. The distribution of CP class at 2 year after ETV treatment was 88.3% in A, 10.8% in B, and 0.9% in C. The improvement of CP class between the two time points was significant (p<0.001). The changes www.selleckchem.com/products/bmn-673.html of

APRI score, FIB-4 index, and FI between the two time points were from 3.2±2.4 to 1.1±0.9 (p<0.001), from 6.8±4.1 to 4.3±3.0 (p<0.001), and from 3.4±0.9 to 2.9±0.9 (p<0.001), respectively.

and the main therapeutic objective after viral suppression. Uncertain SC rates (SCR) in Asian patients treated with modern nucleos(t)ide analogs hamper prediction of treatment duration causing patient trepidation. We conducted a single-center study to evaluate SCR and virologic response (VR) among Asians and non-Asians treated with ETV or TDF. METHODS In HBeAg-positive patients treated with ETV or TDF monotherapy we estimated the cumulative probability of SC (HBeAb synthesis and HBeAg loss) in 1 87 patients (83% Asian) and VR (serum HBV DNA <1000IU/mL) in 145 patients

(78% Asian). Cumulative probability of SC and VR were calculated by ethnicity SPTLC1 and compared using the log-rank test. Cox regression modeled the risk of SC and VR; covariates included gender, age, LAM exposure, HBV genotype and baseline ALT. RESULTS The respective cumulative probabilities of SC on ETV or TDF at year 1, 2, 3, 4 and 5 were 5%, 10%, 16%, 25% and 35% in Asians, and 14%, 39%, 39%, 55% and 55% in non-Asians; differing significantly after year 1 (p<0.002). After adjusting for covariates the probability of SC remained significantly lower in Asians versus non-Asians (HR 0.33, 95%Cl p=0.004). In non-Asians, 2 and 3 year SCR were similar to rates reported in clinical trials. The cumulative probabilities of VR on ETV or TDF at year 1, 2, 3 and 4 were 59%, 77%, 84% and 92% in Asians, and 84%, 88% and 100% in non-Asians, which differed significantly (p<0.05) only in the univariate analysis.

Nonetheless, measures of telomere lengths have the potential to become valuable tools in molecular ecology and forensics for assessing compliance in harvesting situations. “
“Age and reproductive information for Alectinib mw 65 false killer whales stranded in South Africa in 1981 are compared with similar material from 156 animals examined from drive fisheries in Japan in 1979 and 1980. Sizes at birth, sexual maturation, and physical maturity all indicated that both sexes were 10%–20% larger in Japan than South Africa. Females reached sexual maturation at similar ages (8–10.5 yr) in both populations, and although sample sizes were too small to establish male ages at puberty precisely the

ranges in Japan (10.5–18.5 yr) and South Africa (5.25–17.5 yr) were not inconsistent. The initial ovulation rate for females from South Africa was 65% lower (and the apparent pregnancy

rate 82% lower) than those from Japan and there were fewer animals ≤2 yr old within the school, but the magnitude of these differences suggests that the stranded school’s reproductive performance was probably impaired. Collectively these comparisons and the literature indicate substantive size differences between false killer whales in different populations, although the patterns of growth appear similar. Firm conclusions about any geographical differences in reproduction require additional data. False killer whales, Pseudorca crassidens, are distributed worldwide in tropical and warm temperate seas, occasionally extending into cold temperate regions (Baird 2008): Selleck Rapamycin approximate polar limits to distribution have been described as 50ºN and 50ºS (Odell and McClune 1999), although the northern limit of the Glutathione peroxidase summer distribution of this species in the western North Pacific is around 40ºN (as illustrated in Miyashita 1983). In the southern African subregion, the species has been recorded from Gabon

on the Atlantic coast to the Seychelles in the Indian Ocean, with most sightings in water >1,000 m deep but coming close inshore occasionally: at least six mass strandings have occurred in South Africa since 1928 (Best 2007). Despite this widespread distribution, genetic sampling (mainly in the eastern Tropical Pacific but including samples from the North Atlantic, the Indo-Pacific region, and Australia) has revealed considerable population structure, both between and, in the case of the North Pacific, within ocean basins (Chivers et al. 2010). In the latter case, a small population associated with the Hawaiian Islands appears to be genetically distinct from animals occurring further offshore (Chivers et al. 2007), and this separation is supported by longitudinal studies of individually identified individuals (Baird et al. 2008, Baird 2009) and short-term studies of individual movements (Baird et al. 2010).

Methods: Our study included 788 succesive patients chronically infected with HCV evaluated in our Department between June 2007-December 2012 (473 patients with chronic MG132 hepatitis C evaluated by liver biopsy – LB, and 315 patients with liver cirrhosis diagnosed by means of biological, clinical, ultrasonographic and/or endoscopic criteria, in whom we excluded the presence

of ascites). In each patient we performed liver stiffness measurements (LSMs) by using a FibroScan device (Echosens, Paris, France). Ten valid LSMs were performed in each patient, by using the standard M-probe; a median

value was calculated and expressed in kiloPascals (kPa). TE measurements were considered reliable if 10 valid measurements could be acquired with at least 60% success rate and less than 30% interquartile range interval. Results: Reliable LSM measurements were obtained in 84.2% of patients. Mannose-binding protein-associated serine protease The rate of reliable measurements was significantly higher in chronic hepatitis patients (with LB) as compared with cirrhotic patients: 95.9% vs. 66.7%, p<0.0001. In patients with LB, the mean LSMs values (kPa) according to the different stages of fibrosis were: F0-5.2±0.7 (median 4.9), F1-5.6±1.8 (median 5.4), F2-6.7±2.5 (median 6.3), F3-10.1±4.9 (median 8.8) and F4-18.1±5.5 (median 17.1). The best TE cut-offs for predicting various stages of liver fibrosis were: F≥1-6.4 kPa (AUROC=0.783), F≥2 – 6.8 kPa (AUROC=0.751), F≥3 – 7.7 kPa (AUROC=0.810), F=4-12.6 kPa (AUROC=0.954). The mean LSMs values (kPa) were significantly higher in patients with liver cirrhosis diagnosed by means of biological, clinical, ultrasonographic and/or endoscopic criteria as compared with those diagnosed by LB: 31.6±17.8 (median 26.3 kPa) vs. 18.1±5.5 (median 17.1), p<0.0001.

IL-4Ra1 KO mice showed a significantly decreased expression of M2 markers such as YM1 throughout all stages of fibrosis progression and reversal. Using Sirius

red staining and biochemical quantification, CCL4treated mice with systemic and cell specific IL4Ra1 knockout showed significantly less collagen accumulation compared to wildtype controls during fibrosis progression. This was rversed during fibrosis regression. Compared to wildtype littermate controls, IL-4Ra1 ΔLysM but not systemic IL-4Ra1 KO mice showed an attenuated ALT elevation. Interestingly, macrophage markers like CD68, IL-1b, Arg1 and fibrosis related genes such as procollagen α1(I) and αSMA were significantly downregulated in IL-4Ra1 ΔLysM and systemic IL-4Ra1 KO mice during fibrogenesis, but upregulated during fibrosis regression. We show a

central role of IL-4Ra1 signaling in M2 macrophage polarization, with a profibrotic role during liver Alectinib BAY 73-4506 fibrosis progression and a fibrolytic role during its regression. Modulation of IL-4Ra1 by specific pharmacological intervention could be a novel approach to modulate fibrosis progression or induce its reversal.

Two had been treated with peginterferon (PEG)+ribavirin (RBV)+tegobuvir+GS-9451 and 1 with PEG+RBV+ledipasvir+GS-9451. While bone marrow suppression is common with interferon therapy, aplastic anemia has been rare. Whole genome sequencing may identify rare genetic variants and

reveal disease-causing variants in small samples. Methods: DNA extracted from 3 blood samples from studies GS-US-248-0121, GS-US-196-0123, Carnitine palmitoyltransferase II and GS-US-1960140 were sequenced using the Illumina Whole Genome Sequencing (WGS) protocol and HiSeq 2000 sequencer. Average sequence coverage was 35X. Sequences were aligned to the most recent human reference genome (NCBI37/hg19). Entire genome sequences were compared with 425 whole genomes and 1054 whole exome sequenced population controls matched by ethnicity. The analysis focused on listing and prioritizing putatively functional rare (control MAF<0.001) variations predicted to alter amino acid sequence of protein coding genes carried by the aplastic anemia cases. A gene-wise collapsing test was performed to prioritize the genes enriched with such functional variants, and the Ingenuity Pathway Analysis (IPA) was used to analyze the prioritized list. PolyPhen-2 was used to predict the functional effects of genetic variants.

Shah, David Lee, M. Aloysius, Frank G. Gress Purpose: To evaluate retrospectively the safety, technical success and clinical efficacy of hepatic vein stenting in the management of clinically evident hepatic venous outflow obstruction complicating orthotopic liver transplantation. Material and methods: From 2003 to 2013, 24 patients BTK inhibitor ( 8 female and 16 male), including 23 adults and one adolescent

(17 years of age) underwent hepatic vein stent placement for hepatic venous outflow obstruction after orthotopic liver transplant. Pre and post stent deployment pressure gradients were measured. Results: Reduction of pressure gradient was achieved in 23 of 24 patients . Reduction of post stent placement to 3mmHg or below was achieved in 15 of 24 patients. Mean pressure gradient before stenting was 15.5 mmHg with SD of 3.5 mmHg and mean pressure gradient after stenting was 2 mmHg with SD of 2.8 mmHg with mean reduction in pressure of 13.5 mmHg with SD of 6.4 mmHg. There were no immediate major complications

in our population. Mean interval from transplantation to stenting was 570 days. Mean follow-up was 618 days. Analysis of pre and post liver function values is ongoing. Conclusion: Hepatic vein stenting for the treatment of post liver transplant clinically evident hepatic venous outflow obstruction is a safe and technically successful procedure. post stent placement venogram demonstrates resolution of stricture and rapid flow Disclosures: Matthew Johnson – Advisory LY2109761 Committees or Review Panels: Boston Scientific, Guerbet; Consulting: BTG, Bayer, Endoshape; Grant/Research Support: Argon, Bard, B Braun, BTG, ALN, Cook, Cordis; Speaking and Teaching: BTG, Bayer, Cook, Argon; Stock Shareholder: Endoshape The following people have nothing to disclose: Faiz Francis, Thomas Lowe, David Agarwal, Daniel E.

Tau-protein kinase Department of Pathology, Public Health Care Laboratory, Leeuwarden, the Netherlands Focal nodular hyperplasia (FNH) and hepatocellular adenoma (HCA) are two hepatic nodular lesions of different etiologies. FNH, a polyclonal lesion, is assumed to be a regenerative reaction following a vascular injury, whereas HCA is a monoclonal, benign neoplastic lesion. In addition to features that are predominantly found in either FNH or HCA (e.g., dystrophic vessels in FNH and single arteries in HCA), FNH and HCA share morphological vascular abnormalities such as dilated sinusoids. We hypothesized that these anomalous vascular features are associated with altered expression of growth factors involved in vascular remodeling.

18 mL/minute (SD 14.44) for group 2; 96.46 mL/minute (SD 29.33) and 98.21 mL/minute (SD 25.86) for group 3; 87.35 mL/minute (SD 20.27) and 92.23 mL/minute (SD 24.79) for group 4; and 94.86 mL/minute (SD 21.23) and 96.85 mL/minute (29.67) for group 5, respectively. There were no significant differences in the CrCl between the values at baseline and week 12 in all the five groups (P > 0.05). The exact CrCl values at baseline, week 12 (end of LB80380 treatment), and week 36 (end of adefovir treatment) for all individual patients in the five groups are depicted in Fig. 4. Two patients in group 1 experienced selleck kinase inhibitor an increase in creatinine greater than the predetermined amount at week 28 and week 36, respectively.

The CrCl were 78.6 mL/minute and 101.1 mL/minute, respectively. According to our previous study of LB80380 given for 4 weeks in treatment-naïve CHB patients, there is a dose-proportional effect on HBV DNA

reduction with an increasing dose.12 The maximal HBV DNA suppression with 4 logs HBV DNA reduction after 4 weeks is achieved with the dose of equal or higher than 60 mg daily. In the current study, for lamivudine-resistant disease, a dose-proportional effect was also demonstrated with increasing doses of LB80380 up to 150 mg daily. This could be mathematically expressed by the dose-proportional constants for every single log unit increase in the dose for week 4 and this website 12 (Fig. 3). The maximal mean HBV DNA reduction was achieved at the dose of 150 mg daily (group 4) (Table 2, Fig. 2), with 4.16 logs copies/mL reduction after only 12 weeks of treatment. The mean HBV DNA suppression after 1-year treatment of adefovir and of entecavir (1 mg daily) in lamivudine-resistant patients are 4.0 logs copies/mL and 5.1 logs copies/mL, respectively.5, 14 This suggests that greater viral suppression may be achieved by LB80380. In the present study, there was an increase of median HBV DNA at 16 weeks (i.e., 4 weeks after Amino acid switching from

LB80380 to adefovir) in group 5 (Fig. 2). All 13 episodes of virologic rebound occurred after switching to adefovir. The highest dose of LB80380 (group 5) had earlier virologic rebound. This was presumably related to the greater suppression of HBV DNA with this dosage. However, it should be noted that the study was not empowered statistically to compare the efficacy between these two antiviral agents. The HBV DNA reduction achieved by LB80380 and tenofovir appears to be comparable. The mean HBV DNA reduction at week 12 was 4.16 logs copies/mL for LB80380 and 4.5 logs copies/mL for tenofovir.15 However, head-to-head comparative studies must be performed for more definite conclusions. It has been shown in in vitro studies that, of nine mutants resistant to lamivudine, adefovir, entecavir, or telbivudine tested, LB80380 is as potent against six of these as the wild-type virus.13 Two other mutants have a small decrease (<7-fold) in sensitivity to LB80380.

Nine patients (15.0%) receiving telaprevir 2250 mg/day and 32 cases (53.3%) receiving 1500 mg/day underwent RBV dose reduction at the beginning of treatment. In other words, the group receiving telaprevir

Smoothened Agonist 1500 mg/day had a significantly lower initial dose of telaprevir and RBV dose than did the group receiving 2250 mg/day (Table 2). However, in the present study, HCV RNA became undetectable during the 12 weeks of treatment at similar or higher rates in the telaprevir 1500 mg/day group than in the 2250 mg/day group (Fig. 1). In the IL28B TT genotype, the early virological response of the telaprevir 1500 mg/day group was significantly higher than that of the 2250 mg/day group. Although we assessed baseline factors, drug adherence and drug discontinuation rates only in the IL28B TT genotype, there were no significant differences between both groups, except for lower telaprevir adherence up to 12 weeks and a greater number of cases of PEG IFN and RBV dose reductions at the beginning of treatment in the telaprevir 1500 mg/day group. Therefore, the reason for significant differences selleck screening library in the early virological response between both groups is unclear. However, we considered that these results did not affect the SVR rate because

HCV RNA became undetectable in all patients in both groups at 8 weeks after the start of triple therapy. In all cases, IL28B TT cases and non-TT cases, there were no significant differences in SVR rates after triple therapy between those receiving telaprevir 2250 and 1500 mg/day (Figs 3, 4). By examining the detailed course of drug administration from 12–24 weeks (Table 2), we found that the group receiving telaprevir 1500 mg/day had a lower discontinuation rate of telaprevir and higher adherence to RBV and PEG IFN up to 24 weeks in spite of the low initial RBV dose. Furthermore,

hemoglobin levels showed greater reductions during triple therapy with telaprevir 2250 mg/day than with telaprevir 1500 mg/day, and the group receiving telaprevir 2250 mg/day had a significantly higher discontinuation rate of telaprevir due to anemia than did the group receiving telaprevir C-X-C chemokine receptor type 7 (CXCR-7) 1500 mg/day (Fig. 2). Therefore, telaprevir 1500 mg/day may be a safe option as part of triple therapy, while maintaining PEG IFN and RBV adherence. Viral breakthrough or relapse can occur during telaprevir monotherapy or telaprevir plus PEG IFN dual therapy (without RBV) because of the development of mutations that confer resistance to telaprevir.[14, 27-29] Furthermore, in a Japanese phase III trial of triple therapy in relapsers and non-responders who had not achieved SVR to a previously administrated IFN-based regimen, SVR rates increased as RBV adherence increased, particularly in previous non-responders.
