Symonds – Employment: Gilead John G. McHutchison – Employment: Gilead Sciences; Stock Shareholder: Gilead Sciences The following people have nothing to disclose: Fernando E. Membreno Objective: To evaluate the resistance profile of the NS5A inhibitor LDV in GT 1, chronically infected HCV subjects treated with non-SOF, LDV-containing

regimens for up to 24 weeks. Methods: Six phase 2 studies were analyzed. Studies GS-US-248-0120, GS-US-248-0131, and GS-US-248-0132 evaluated the all oral regimens of either 30 or 90 mg LDV ± the NS3 protease inhibitor vedroprevir (VDV, GS-9451) ± the non-nucleoside NS5B polymerase inhibitor tegobuvir (TGV, GS-9190) Target Selective Inhibitor Library ic50 ± riba- virin (RBV). Studies GS-US-248-0121, GS-US-256-0124, and GS-US-256-0148 evaluated 30 mg LDV ± VDV with pegylated interferon (IFN) + RBV. NS5A population sequencing was attempted for all subjects at baseline and for any subjects who experienced virologic breakthrough, virologic relapse, or early discontinuation Afatinib with HCV RNA >1000 IU/mL. Phenotypic analyses using transient HCV replicon assays were conducted for novel conserved substitutions observed in the first 150 amino acids of NS5A in two or more subjects or >1% of subjects for the remainder of NS5A. LDV resistance-associated variants (RAVs) previously identified include:

K24G/N/E/R, M28T/ A/G, Q30T/L/H/R/G/K/E/D, L31I/M/V, P32L, H58D/L, and Y93C/H/S/L for GT 1a, and L31V/M and Y93H for GT 1b. Results: Overall, 1103 GT 1 subjects (747 GT

1a, 297 GT 1b) were randomized and treated; 1045 (94.7%) had baseline NS5A population sequencing results. Previously identified LDV RAVs were observed in 89 (8.5%) subjects (47 GT 1a [6.3%], 42 GT 1b [14.1%]) at baseline and resulted in numerically lower SVR rates compared to overall SVR rates in most studies. In total, 335 (30.3%) subjects qualified for post-treatment resistance analyses; NS5A sequencing was successful for 329 (287 GT 1a, 42 pheromone GT 1b). Of these, 328 (99.7%) had previously identified LDV RAVs detected, in which 55% GT 1a subjects had 2-5 LDV RAVs whereas only 29% GT 1b subjects had multiple RAVs. In addition, LDV RAVs with >10% prevalence were observed more frequently in GT 1a subjects (M28T, Q30R/E, L31M, H58D, Y93C/N) than GT 1b subjects (Y93H). On-treatment and baseline sequences were compared to determine novel amino acid substitutions that may be associated with LDV resistance. Eleven GT 1a and 1 GT 1b conserved substitutions occurred in multiple subjects and were assessed for LDV susceptibility. Three substitutions (K26E and S38F in GT 1a and L31I in GT 1b) were found to exhibit reduced susceptibility to LDV. Conclusions: Virologic breakthrough and virologic relapse on non-SOF, LDV-containing regimens are associated with the presence of known LDV RAVs at failure. The GT 1a substitutions K26E and S38F and the GT 1b substitution L31I were identified as novel LDV RAVs. Disclosures: Kathryn M.

Liver biochemistry was analyzed by routine automated laboratory assays: total bilirubin, alanine aminotransferase (ALT); aspartate aminotransferase (AST), GGT, and ALP. Blood samples from controls were taken preoperatively. Sepsis was defined according to Bone criteria as suspected or documented

infection on the day of admission to the ICU and fulfillment of at least two of the three criteria for the systemic inflammatory response syndrome (receiving ventilatory support, white-cell count ≤4,000 or ≥12,000 per cubic millimeter, and body temperature ≤36°C or ≥38°C).12 Serum concentrations of cytokines BMS-777607 purchase were quantified by a multiplexed microbead suspension enzyme-linked immunosorbent assay (Biosource, Carlsbad, CA) using the

Luminex 100 system (Austin, TX) as published.13 Individual serum BAs were quantified by high-performance liquid chromatography / mass spectrometry using authentic BA standards and deuterated internal standards.14 Total RNA was isolated and quantified as described.15 Commercial gene expression assays from Applied Biosystems were used and are listed in Supporting Data Table 4. Data are expressed as fold increase relative to the mean of the control patients. Immunoblot analysis of CYP7A1 was performed as described in the online supplement. For histological and immunohistochemical analysis, liver sections from a randomly chosen subset of study patients (40 ICU and 10 controls) were used. Four-μm-thick sections were cut from SAR245409 cost frozen samples and stained with hematoxylin and eosin for a general histological assessment. For evaluation of bilirubinostasis GNAT2 and ductular reaction, sections were stained by Hall’s method and for cytokeratin 7 (CK7) (Dako, Glostrup, Denmark). For immunohistochemistry, 5-μm-thick frozen sections were dried overnight at room temperature, fixed in acetone for 10 minutes, and washed in phosphate-buffered saline (PBS) immediately prior

to use. Sections were incubated with primary antibodies for 30 minutes at room temperature. The primary antibodies used are listed in Supporting Data Table 5. For the staining of CK7, OATP2/8, MRP3, MRP2, MDR1, and MDR3 the second and third step consisted of peroxidase-labeled rabbit anti-mouse and peroxidase-labeled swine anti-rabbit immunoglobulins (both Dako). Secondary and tertiary anti-bodies were diluted (1:50 and 1:100, respectively) in PBS (pH 7.2) containing 10% normal human serum. For the staining of BSEP, the slides were incubated with an anti-rabbit peroxidase-conjugated Envision antibody (Dako) and subsequently incubated with a goat peroxidase anti-peroxidase complex (goat PAP complex; Dako). For NTCP staining a protein block was performed prior to the application of the primary antibody to counteract the strong sinusoidal staining and the secondary step consisted of peroxidase-labeled swine antirabbit IgG (dilution 1:100; Dako), followed by peroxidase-labeled rabbit anti-swine IgG (dilution 1:100; Dako).

2B). Moreover, the expression level of EIF5A2 appeared to be higher at the edge of the wound in LO2-EIF5A2 cells (Supporting Fig. S3); however, it was less obvious than that observed in tumor samples (Fig. 1E,F). The transwell migration assay showed that overexpression of EIF5A2 led to a marked increase in cell motility, as more cells were observed migrating through the 8-μm pores in LO2-EIF5A2 compared with control LO2-Vec (P < 0.05, Fig. 2C). Similarly, the invasion assay showed that LO2-EIF5A2 cells obtained a significantly higher rate of cell invasion than that of control cells (P < 0.01, Fig. 2D). These

data demonstrate that overexpression of EIF5A2 in LO2 cells enhanced cell motility. To test whether EIF5A2 overexpression is causative in an experimental metastasis buy Saracatinib model, we injected LO2-EIF5A2 cells into the tail vain of SCID mice; LO2-Vec were used as control (five mice per group). Mice were sacrificed 6 weeks after cell injection and metastatic tumor nodules

formed in the lung and in the liver were examined. No tumor Dactolisib purchase nodules were detected in the lung in any mice examined. However, overexpression of EIF5A2 increased liver metastasis by 2-fold, as shown in Fig. 3A. Interestingly, higher-level expression of EIF5A2 was also observed in cancer cells invading the surrounding tissue as described before (Fig. 3B, indicated by arrows). We next studied whether endogenous EIF5A2 is important for cancer cell motility. High-level EIF5A2 expression was detected in several liver cancer cell lines including H2M (Fig. 1C), a metastatic liver cancer cell line established from metastatic lesion of a liver cancer patient.23 We evaluated the effect of EIF5A2 silencing by RNAi on H2M cell migration. Compared with scrambled siRNA (siSCR), treatment with specific siRNA against

EIF5A2 (siEIF5A2) resulted in about 80% silencing of EIF5A2 in H2M cells at both mRNA and protein levels, whereas EIF5A remained unaffected (Fig. 4A,B). Further study showed that EIF5A2 knockdown could significantly inhibit cell migration in H2M cells (Fig. 4C, P < 0.05). Posttranslational hypusination, which is mediated by DHPS, is required for EIF5A Amisulpride to function properly.5, 8 We speculated that this would also be an essential maturation step for EIF5A2 due to their high level of sequence homology, especially at the region of hypusine modification.12 It is therefore expected that inhibiting the maturation of EIF5A2 by DHPS inhibitor N1-guanyl-1,7-diaminoheptane (GC7) could inhibit the effect of EIF5A2 on cell motility. Indeed, a reduction in cell motility was observed in H2M cells treated with 200 μM GC7 for 16 hours (Fig. 4D); however, the effect was not as profound as that seen in cells treated with siEIF5A2.

As a result, 93% of subjects met the response-guided criteria and underwent 24 weeks of treatment. The overall SVR12 rate was 79%; 70% (78/111) in genotype 1a and 86% (128/149) in genotype 1b. In this way, in clinical trials of SMV-based triple therapy regimens with relapsers following previous IFN therapy, majority of subjects met the response-guided criteria

and underwent 24 weeks of treatment. The SVR rate for the Japanese studies was 90–97%, and in the overseas studies it was 86% for genotype 1b, significantly higher than the SVR rate in the control groups administered 48 weeks of Peg-IFN + RBV MG-132 clinical trial dual therapy. In the Japanese CONCERTO-2 trial,[10] non-responders to previous IFN therapy were administered SMV + Peg-IFNα-2a + RBV triple therapy for 12 weeks (SMV 12W group) or 24 weeks (SMV 24W group). The total treatment duration for both groups was set using response-guided criteria similar to those for the CONCERTO-1 trial,[9] with 96% and 98% of subjects, who completed 24 weeks of treatment respectively, meeting the criteria

and finishing the treatment at 24 weeks. The SVR24 rate was 51% (27/53) for the SMV 12W group, and 36% (19/53) for the SMV 24W group (Fig. 3). In the CONCERTO-4 trial,[11] non-responders were administered SMV + Peg-IFNα-2b + RBV triple therapy for 12 weeks, followed learn more by Peg-IFNα-2b + RBV dual therapy for 36 weeks, for a total treatment duration of 48 weeks. The SVR24 rate was 38% (10/26) (Fig. 2). Although the Japanese CONCERTO-2[10] and CONCERTO-4[11] trials were conducted with non-responders, they did not conduct any further analyses subdividing non-responders into partial responders, with a decrease in the HCV RNA level by ≥2 log IU/mL at week Methane monooxygenase 12 of the previous treatment, and null responders, with a decrease < 2 log IU/mL. On the other hand, the overseas phase II ASPIRE trial,[8] conducted with relapsers and non-responders, reported therapeutic results separately for partial responders and null responders.

This trial assigned subjects to one of 3 groups, all with a total treatment period of 48 weeks. They were administered SMV + Peg-IFNα-2a + RBV triple therapy for 12 weeks or 24 weeks, followed by Peg-IFNα-2a + RBV dual therapy for the remaining time, or triple therapy for the entire 48 weeks. SMV was administered in a daily dosage of either 100 mg or 150 mg. The SVR rate for the SMV 12, 24 and 48 week groups was 70%, 66% and 61%, respectively, at the 100 mg dosage, and 67%, 72% and 80% at the 150 mg dosage, with no difference seen between groups due to treatment duration. The SVR rate in relapsers was 85% for both the 100 mg and 150 mg dosages. On the other hand, the SVR rate for partial responders and null responders was 57% and 46%, respectively, at the 100 mg dosage of SMV, and 75% and 51% at the 150 mg dosage. This indicates that within the non-responders, a higher SVR rate is achieved in partial responders than in null responders.

5E) could be important not only for development of HCCs but also for other tumor types. The inverse correlation between selenium levels and tumor size described here in HCC patients is consistent with several epidemiologic studies. An inverse relation between plasma selenium levels and HCC risk was observed in Taiwan.18 Based on previous animal experiments60 an intervention trial was performed in Quidong/China, a region with low selenium intake. Daily doses of 200 μg selenium decreased HCC rates by 35% and cessation of selenium supplementation brought tumor rates back to initial values.17,

60-62 Consistently, an intervention study in the USA demonstrated protection by selenium against prostate cancer.63 In contrast, IAP inhibitor the more recent SELECT study did not show any benefit of selenium

supplementation.64 This might, however, be due to the high baseline find more plasma levels of selenium observed in this study that could conceal potentially beneficial effects of selenium supplementation. Although comparison of selenium levels between different studies is difficult because of inconsistent methodologies, conclusions can be drawn from environmental parameters. In particular, low selenium concentrations in the serum have been documented for the Austrian population that are due to low selenium in the soil.65 In conclusion, the mechanistic data in the present study support the notion that the inverse correlation between selenium levels and the risk to develop HCC may have a causal Meloxicam basis. Therefore, selenium supplementation could be considered a strategy for chemoprevention or additional therapy for HCC patients

with low selenium levels. We thank M. Seif, E. Hangelmann, M. Eisenbauer, and N. Kandler for excellent technical assistance, M. Vidali for help in optimization of LOOH-Ab detection, M.

“Aim:  The aim of this study was to evaluate the feasibility of gadolinium ethoxybenzyl diethylene triamine pentaacetic acid (Gd-EOB-DTPA) in magnetic resonance imaging (MRI) to assess the ablative margin of radiofrequency (RF) ablation to hepatocellular carcinoma (HCC). Methods:  RF ablation was performed in the livers of six pigs after the i.v. administration of Gd-EOB-DTPA 20 min before ablation. Three pigs were killed 2 h after administration (group A), and the other pigs were killed 7 days after ablation (group B). Thereafter, correlation between pathological findings and MRI was investigated. Moreover, the Gd concentrations were examined in ablated and non-ablated regions. An initial clinical evaluation was conducted for 28 HCC nodules.

Results: 319 patients had 343 grafts transplanted during the study period. 155/319 patients were alive at 15 years post transplant. Of these 155 patients, 74 are currently alive between 15–20 years, 52 are currently alive beyond 20 years and 29 died. The causes of end-stage liver disease in patients EGFR inhibitor surviving beyond 20 years were autoimmune disease (AIH, PBC and PSC) followed by chronic viral hepatitis (HCV and HBV), fulminant liver failure, and metabolic disease. The primary indication for liver transplantation (p = 0.067) and recipient gender (p = 0.105) did not affect patient survival beyond 20 years. The commonest causes of patient death beyond 15 years were sepsis

(7/29), de-novo malignancy (6/29) and graft dysfunction (6/29). The average age at the time SB203580 in vitro of transplant in recipients surviving 15, 15–20, beyond 20 years is 43.6, 42.6, and 40.6 years of age. The average age of the 29 patients that died beyond 15 years post transplant

was 46.5 years. The average donor age in recipients surviving at 15, 15–20 and beyond 20 years is 33, 34, and 30 years of age respectively. The average donor age in recipients who were deceased beyond 15 years was 35.1 years. The average BMI of recipient surviving at 15, 15–20 and beyond 20 years is 25.7, 25.7, and 25.4. Conclusion: In this study, patients surviving beyond 15 years were not associated with an increasing BMI. Primary indication for liver transplantation and recipient gender did not affect survival beyond 20 years. The greatest threat to long-term survival was due to de-novo malignancy, sepsis and age related complications.

Corresponding author: v.chachay @uq.edu.au Background: Non-alcoholic fatty liver disease (NAFLD) is a common cause of chronic liver disease, featuring hepatocyte triglyceride accumulation (steatosis), insulin resistance (IR), dyslipidemia, and increased cardiovascular risk. Potential pharmacological treatment should target both hepatic and cardiometabolic dysregulation. The nutraceutical approach is the use of bioactive food-constituents at pharmacological doses for therapy.

Methods: A total of 42 male wistar rats were randomly divided into three groups: the control group (n = 12), the model group (n = 15), and the Olmesartan group (n = 15). selleckchem With the exception of those in the control group, all rats were given subcutaneous injections of 40 % CCl4 once every three days, 5 mg/kg for the first dose and 3 mg/kg for each subsequent dose. Rats in the control group were given subcutaneous

injections of oil in the same dosage, and from the first day, rats in Olmesartan group were given Olmesartan (4 mg/kg/d) by intragastric administration. All rats were killed after 60 days. Histopathological study of the liver tissues was done with hematoxylin-eosin (HE) and Masson staining. Ang(1–7) levels were determined by enzyme-linked immunosorbent assay (ELISA). The expression of ACE2 and Mas receptor mRNA were evaluated by Real-time PCR. The expression of ACE2 and Mas receptor protein were evaluated by Western blotting. see more Results: (1) Pathological results: compared with the control group, the degree of hepatic fibrosis was increasing in the model group and the Olmesartan group, and in the Olmesartan

group the degree of hepatic fibrosis was lower than in the model group. (2) ELISA results: the Ang(1–7) level of the model group and the Olmesartan group increased compared with the control group (P < 0.05); Resveratrol and the Ang(1–7) level of the Olmesartan group

increased compared with the model group (P < 0.05). (3) Real-time PCR results: ACE and Mas receptor mRNA expression in the model group and the Olmesartan group increased compared with the control group (P < 0.05); and in the Olmesartan group ACE2 and Mas receptor mRNA expression increased compared with the model group (P < 0.05). (4) Western blotting results: ACE2 and Mas receptor protein expression of the model group and the Olmesartan group increased compared with the control group (P < 0.05); and in the Olmesartan group ACE2 and Mas receptor protein expression increased compared with the model group (P < 0.05). Conclusion: Olmesartan attenuated the degree of hepatic fibrosis, not only by inhibiting the effect of Ang II/AT1R, but also by activating the ACE2-Ang(1–7)-Mas receptor axis. Key Word(s): 1.

Taken together, the results of the various studies raised two important clinical questions: Why does platelet-derived FVIII but not endothelial cell-derived FVIII work in the presence of anti-FVIII

inhibitors? Why does platelet-derived FIX not work in the presence of anti-FIX inhibitors? It was hypothesized that maintenance of efficacy with platelet-derived FVIII related to: (i) the association of VWF/FVIII in platelets (preformed complex); (ii) a time-dependent inactivation of FVIII by inhibitors (2 h incubation in the Bethesda assay). These factors were believed to play a potentially critical role in a platelet-derived FVIII gene therapy approach to the management of inhibitors in patients with haemophilia. The main clinical question to be answered was: How does VWF affect the reactivity of anti-FVIII inhibitors? To address PF-02341066 clinical trial this question, a series of experiments were conducted using two different approaches: In vitro: chromogenic-based Bethesda assay. In vivo: haemophilia A mouse models. Brief descriptions of the various experiments and results

are provided below [31]. The FVIII coagulant (FVIII:C) activity of recombinant human FVIII (rhFVIII) at concentrations ranging from 0 to 1.0 U mL−1 with and without VWF 1 U mL−1 was investigated in the Bethesda assay. The presence of VWF had no significant effect on apparent FVIII:C in the chromogenic assay although there was a tendency towards slight enhancement of activity [31]. The selleck kinase inhibitor FVIII:C activity of rhFVIII at low (0.1 U mL−1) and high (1.0 U mL−1) concentrations was investigated in the presence of VWF at concentrations Amobarbital ranging from 0 to 2.0 U mL−1. A slight but non-significant increase in apparent FVIII:C activity was observed with increasing concentrations of VWF [31]. The potential effect of plasma on the FVIII chromogenic assay was then explored. In this instance, apparent FVIII:C activity was measured after adding rhFVIII to the assay in the presence of plasma at dilutions ranging from

1/10 to 1/120 (derived from FVIIInull mice) or from 1/10 to 1/160 (derived from VWFnullFVIIInull mice). Both types of mouse plasma suppressed the apparent FVIII:C activity but, in each case, the suppression was overcome by dilution of the plasma to at least 1:40 [31]. To explore whether VWF affects the measurement of FVIII inhibitors in vitro, inhibitory antibodies from three sources were used: Immunized VWFnullFVIIInull mouse plasma containing murine polyclonal antibodies (mPoAb). Purified plasma IgG from human inhibitor patients containing human polyclonal antibodies (hPoAbs). Cloned human monoclonal antibodies from inhibitor patients containing human monoclonal antibodies (hMoAb). Inhibitors were incubated with rhFVIII either with or without the presence of recombinant human VWF (rhVWF) at a concentration of 1 U mL−1.

Median duration of ETC treatment was 38 months (6-66). Cumulative CVR rates in NA-naïve and experienced patients were 69% vs. 54% at 12th month and 84% vs. 68% at 24th month, 92% vs. 86% at 36th month, respectively (Fig.1, log-rank, p=0.32). 3 patients (10.3%) in NA-experienced group and 4 patients in NA-naïve group (2.2%) required a switch to tenofovir (TDF) due to sub-optimal response to ETC (p=0.061) and 1 NA-naïve patient developed ETC resistance (L180M, M204V, S202G). Multi-variate

logistic regression analysis showed that HBeAg positiv-ity (OR: 6.3, 95% CI 1.16-34.3, p=0.033) and previous LAM experience (OR: 5.8, 95% CI 1.15-29.2, p=0.033) were independent predictors for a requirement Talazoparib to switch to TDF. Conclusion: ETC has a potent antiviral efficacy in patients with CHB. The antiviral efficacy of ETC is not influenced by prior treatment with NAs if LAM resistance is excluded at baseline. However, HBV-DNA kinetics should be carefully monitored in patients with HBeAg-positive CHB and previous LAM experience. Disclosures: The following people have nothing to

TDF has been demonstrated potent antiviral in clinical trials, but real-life data in Asian-Americans are lacking. We prospectively followed patients on TDF for 144 weeks and assessed outcomes. Methods: Asian-American patients with CHB from multiple community-based practices were prospectively enrolled and treated with TDF (300 mg/day) in a single arm study for 48 weeks. After week 48, patients had the option to continue TDF up to week 144, or opt out of further observation. The primary efficacy endpoint was hepatitis B virus (HBV) DNA < 29 IU/mL at week 48 very and 144. Secondary endpoints were safety and tolerability, serologic and biochemical

responses, liver fibrosis by FibroTest at week 48, and the development of drug resistant mutations. Results: Ninety patients were enrolled with baseline values in Table 1. At week 48, seventy four patients (82% overall; 70% HBeAg-positive and 100% HBeAg-negative) had HBV DNA <29 IU/mL. 12% (6/52) HBeAg+ patients achieved HBeAg loss/seroconversion. The percentage of patients with alanine aminotransferase (ALT) in the normal range increased from 26% at baseline to 66% at week 48. The percentage of patients with F0 fibrosis by FibroTest increased from 48% to 51%, and those with F4 fibrosis decreased from 4% to 1 %. At week 48, 31 /90 patients (19 HBeAg+) opted to continue on TDF with assessment at 12 week intervals up to week 144. Two patients with HBV viremia did not participate beyond week 48. At week 144, 84% (26/31) patients had HBV DNA <29 IU/mL; No viremic patient (n=5) had genotypic mutation on Sanger sequencing (2/5 TDF non-adherence); 67.

Harassment is also often used by subordinates to modify the behaviour of dominants. For example, hungry individuals sometimes harass successful foragers or hunters for a share of the food that selleck kinase inhibitor they have acquired and adolescents of either sex may harass copulating couples (Clutton-Brock & Harvey, 1976; Clutton-Brock & Parker, 1995b). More generally, the stress induced by social conflicts varies across species depending on the structure

of societies as well as within societies depending on social dynamics, and may be higher in dominants than in subordinates when the costs of acquiring and maintaining dominance are very high (Goymann & Wingfield, 2004; Rubenstein & Shen, 2009). In many social mammals where selleck compound females are philopatric, female group members (who are often close kin) compete with each other

to breed and raise young (Clutton-Brock, 2009b; Clutton-Brock & Lukas, 2011). Regular aggression directed by dominant females at subordinates or their offspring is common, especially in species living in large groups, where average coefficients of relatedness are relatively low and females belonging to different kin groups compete with each other to breed and rear young. Competition between females often inhibits females from mating and can depress the fertility of subordinates, disrupting their reproductive cycles and causing them to down-regulate their reproductive systems (Wasser & Barash, 1983; Young, 2009). For example, in yellow baboons, dominant females direct frequent aggression at cycling subordinate females in the follicular phase and these attacks can increase the number of cycles before conception (Wasser & Starling, Pazopanib datasheet 1988), while in other species (including several rodents, some carnivores and almost all of the marmosets and tamarins) subordinates are temporarily infertile (Young, 2009). As well as disrupting reproduction, regular aggression can lead to increased rates of abortion and reductions in juvenile survival (Silk, 2007a; Stockley & Bro-Jorgensen, 2011). For example, in

hamsters, interactions between subordinate and dominant females shortly after mating increase implantation failures in subordinates, while interactions later in pregnancy lead to increased rates of foetal mortality (Huck, 1988a, b). Studies of several species suggest that reproductive suppression intensifies when resources are limited and eases when they are abundant (Young, 2009; Clutton-Brock et al., 2010). For example, in Damaraland mole rats, physiological suppression of subordinate females is relaxed during the annual rains when ecological constraints are relaxed (Young et al., 2010) while, in meerkats, dominant females are more likely to tolerate subordinate reproduction when food is abundant (Clutton-Brock et al., 2010).
