“Background In a subset of patients, anti tumour necrosis factor (TNF) therapeutic antibodies are immunogenic, resulting in the formation of antidrug antibodies (ADAs). Neutralising ADAs compete with TNF for its binding site and reduces the effective serum concentration, causing clinical non-response. It is however unknown to which extent ADAs are neutralising. Objectives To study which proportion of antibodies to human(ised) anti-TNF (adalimumab, golimumab, certolizumab) as well as chimeric anti-TNF (infliximab) is neutralising. Methods Neutralising capacity of ADAs was assessed using a TNF competition assay in ADA-positive

sera of patients treated with adalimumab (n=21), golimumab (n=4), certolizumab (n=9) or infliximab (n=34) sent in to our diagnostic department. Results In 34 sera with ADAs to adalimumab, golimumab or certolizumab, EGFR inhibitor bigger than 97% of the antibodies were neutralising. In 34 sera with ADAs to infliximab bigger than 90% of the antibodies were neutralising. Further characterisation of the broader antibody response BEZ235 to infliximab revealed that non-neutralising antibodies to infliximab do not target murine domains, but may bind infliximab-unique domains not involved in TNF binding (located outside the paratope). Conclusions Our study shows that ADAs to human (ised)

as well as chimeric anti-TNF therapeutic antibodies are largely neutralising. This highly restricted ADA response suggests an immunodominant Nepicastat mw role for the paratope of anti-TNF therapeutics.”
“Background and aims: Previous clinical trials suggest that adding non-selective beta-blockers improves the efficacy of endoscopic band ligation (EBL) in the prevention of recurrent bleeding, but no study has evaluated whether EBL improves the efficacy of beta-blockers + isosorbide-5-mononitrate. The present study was aimed at evaluating this issue in a multicentre randomised controlled trial (RCT) and to correlate changes in hepatic venous pressure gradient (HVPG) during treatment with clinical outcomes\n\nMethods: 158 patients with cirrhosis,

admitted because of variceal bleeding, were randomised to receive nadolol+isosorbide-5-mononitrate alone (Drug: n = 78) or combined with EBL (Drug+EBL; n = 80). HVPG measurements were performed at randomisation and after 4-6 weeks on medical therapy.\n\nResults: Median follow-up was 15 months. One-year probability of recurrent bleeding was similar in both groups (33% vs 26%: p = 0.3). There were no significant differences in survival or need of rescue shunts. Overall adverse events or those requiring hospital admission were significantly more frequent in the Drug+EBL group. Recurrent bleeding was significantly more frequent in HVPG non-responders than in responders (HVPG reduction >= 20% or <= 12 mm Hg). Among non-responders recurrent bleeding was similar in patients treated with Drugs or Drugs+EBL.

All scores had significant

improvement postoperatively when compared with preoperative scores.\n\nOur data demonstrate that reoperative laparoscopic paraesophageal herniorrhaphy can produce excellent results, comparable to first-time repair.”
“Coronary artery disease (CAD) and acute myocardial infarction (AMI) are associated with a reduction of heart rate variability (HRV). The aim of this study was to compare the HRV of CAD patients with and without AMI (CAD-AMI) with health-matched controls by linear (spectral analysis) and nonlinear [Shannon entropy (SE), conditional entropy (CE) and symbolic analysis (SA)] analysis.\n\nFifty-eight men were divided into three groups: healthy selleck screening library (n = 19, 57 +/- A 4 years), CAD (n = 20, 56 +/- A 10 years) and CAD-AMI (n = 19, 54 +/- A 12 years). The RR intervals were recorded at rest in the supine position for 10 min with an HR monitor (Polar(A (R))S810i). A series of 250 beats was selected to analyze variance, spectral analysis, SE, CE [complexity index (CI), Anlotinib molecular weight normalized CI (NCI)] and SA (0V, 1V, 2LV and 2ULV patterns), as well as 0V (no significant variation) and 2ULV (two significant unlike variations), which reflect sympathetic and vagal modulation, respectively. One-way ANOVA (or the Kruskal-Wallis test when appropriate) and Pearson correlation were used.\n\nThe CAD group had higher body mass index and weight than the

CAD-AMI group, but no differences were found between the healthy and AMI groups. There were no differences between the groups regarding linear and nonlinear analysis. The 0V and 2ULV patterns were significantly correlated with the SE, CI and NCI of the three groups.\n\nThere was no difference between the groups regarding cardiac autonomic modulation by linear STI571 price and nonlinear methods, which may be due to beta-blocker use, coronary angioplasty and the exercise capacity of healthy subjects.”
“Background: Women

at increased (genetic) risk of breast cancer have to weigh the personal pros and cons of prophylactic mastectomy (PM) as an option to reduce their cancer risk. So far, no routine referral to a psychologist has been investigated for women considering PM. Aim of this study was to asses: 1) the acceptance of the offer of a standard psychological consultation as part of pre-surgical decision-making in high-risk women, 2) reasons for PM and reasons for postponing it, 3) the need for additional psychological interventions, and factors associated, and 4) the frequency of psychiatric/psychological treatment history.\n\nMethods: During a 30 months period, women at high risk considering PM were offered a psychological consultation. The content of these, and follow-up, consultations were analyzed.\n\nResults: Most women (70 out of 73) accepted the psychological consultation, and 81% proceeded with PM. Main reasons for undergoing PM were to reduce anxiety about cancer, and to reduce the cancer risk.

01), with these values for main lipids fractions, saturated fatty acid (SEA), monounsaturated find more fatty acid

(MUFA) and polyunsaturated fatty acid (PUFA), respectively: 42.86%, 43.27% and 13.87 for JA and 46.87%, 46.96% and 6.20% for CE. SEA and MUFA percentages were slightly higher in CE at the expense of PUFA, specifically in the n-6 series, where values of 11.06% in JA and 3.91% in CE were obtained. In both products, the most prevalent fatty acid was a monounsaturated fatty acid, oleic acid, with percentages of 37.28% in JA and 38.48% in CE. Other fatty acids with higher percentages, with respect to total fat, were two saturated fatty acids: palmitic acid, 20.63% in JA and 22.95% in CE, and stearic acid, 18.65% in JA and 17.14% in CE.”
“Aim: To investigate the potential antidepressant and anxiolytic effects of Neu-P11, a novel melatonin agonist, in two models of depression in rats and a model Nirogacestat of anxiety in mice.\n\nMethods: In the learned helplessness test (LH), Neu-P11 or melatonin (25-100 mg/kg, ip) was administered to rats 2 h before the beginning of the dark

phase once a day for 5 days and the number of escape failures and intertrial crossings during the test phase were recorded. In the forced swimming test (FST), rats received a single or repeated administration of Neu-P11 (25-100 mg/kg, ip). The total period of immobility during the test phase was assessed. In the elevated plus-maze test (EPM), mice were treated with Neu-P11 (25-100 mg/kg, ip) or melatonin in the morning or in the evening and tested 2 h later. The percentage

of time spent Selleckchem Small molecule library in the open arms and the open arms entries were assessed.\n\nResults: In the LH test, Neu-P11 but not melatonin significantly decreased the escape deficit and had no effect on the intertrial crossings. In the FST, a single or repeated administration of Neu-P11, either in the morning or in the evening, significantly decreased the duration of immobility. In the EPM test, Neu-P11 significantly increased the percentage of time spent in the open arms and the open arms entries irrespective to the time of administration. Melatonin was effective only when administered in the afternoon.\n\nConclusion: The results demonstrate that Neu-P11 exerts antidepressant and anxiolytic activities in rodent models.”
“Association of HBV genotypes (especially A and D) with severity of liver disease is controversial. We studied the influence of HBV genotypes on liver disease severity among Indian patients.\n\nWe selected 247 HBV infected patients (42 acute hepatitis, 87 carriers, 44 chronic hepatitis B [CHB], 35 liver cirrhosis [LC] and 40 hepatocellular carcinoma [HCC]). Genotyping of stored sera was performed using genotype-specific enzyme-linked immunosorbent assay (ELISA) and restriction fragment length polymorphism (RFLP). The distribution of genotypes in disease states of differing clinical, histological and biochemical severity were compared.

81.3 +/- 16.7 s; p = 0.049). Concentration of fibrinogen and factor VIII activity were lowest during night time (22:00-4:00 h). These findings demonstrate a circadian rhythm in platelet function as measured with the PFA-100 (R). The PFA-100 (R) seems to be an appropriate tool to describe circadian alterations and is easier to use than optical aggregometry in analogous studies.”
“The aim of this study was to evaluate variations of O6-methylguanine-DNA methyltransferase (MGMT) promoter methylation and protein expression after adjuvant treatment in glioblastoma patients. Sixteen patients with a glioblastoma underwent 34 microsurgeries including 18 re-operations. IPI-145 manufacturer After surgery, patients underwent follow-up with radiotherapy and chemotherapy (temozolomide, ACNU and cisplatin)

between 2000 and 2008. To investigate MGMT methylation and MGMT expression, methylation-specific PCR (MSP) and immunohistochemical staining (IHC) were performed. The methylation status of the MGMT promoter was altered in five (27.8 %) of 18 re-operation specimens. In four specimens, the MGMT promoter was found to be methylated after primary surgery, but was found to be unmethylated MG-132 supplier on post-treatment samples. MGMT protein expression was altered in 15 (83.3%) of 18 cases. Fifteen specimens showed higher levels of protein expression as compared to previous samples and three samples demonstrated a similar expression pattern. After irradiation and exposure to steroid and temozolomide 6 and 24 h later, a methylated MGMT promoter and negative

protein expression were seen in U343 glioblastoma cell lines which have methylated promoter and negative protein expression. Variations in MGMT promoter methylation and protein expression can occur after treatment. We suggest that changes of MGMT promoter methylation and protein expression might not be related to a direct effect of irradiation and exposure to steroid and temozolomide.”
“Mobile target detection is a significant application in wireless sensor networks (WSNs). In fact, it is rather expensive GW4869 to require every part of the region of interest (RoI) to be covered in a large-scale WSN for target detection. Trap coverage has been proposed to trade off between sensing performance and the cost of sensor deployments. It restricts the farthest distance that a target can move without being detected rather than providing full coverage to the region. However, the results cannot be directly applied in a real WSN since the detection pattern of a sensor in practical scenarios follows a probabilistic sensing model. Moreover, the trap coverage model does not consider the various moving speeds of targets, which is important for trapping targets.

Criteria for measuring metatarsal sesamoidal distances to the radiographic plate are established, along with application of the criteria to a control population. The principle of radiographic image distortion as it relates to these objects is presented, PLK inhibitor and, based on a predetermined range of radiographic angles, radiographic image distortion is calculated for the metatarsal head and the tibial sesamoid

separately.\n\nResults: By using accepted trigonometric principles, a mathematical model is developed that makes it possible to collectively quantify image shift between the two objects.\n\nConclusions: Criteria are established that, if followed, should minimize image distortion when it is important to measure metatarsal

sesamoidal distances. (J Am Podiatr Med Assoc 100(1): 1-9, 2010)”
“The bacury tree is a native fruit species of great socio-economic importance of North and Mid-North regions of Brazil. However, there is insufficient scientific knowledge on the species, especially on its floral biology, reproductive mechanisms and pollen viability. Knowledge about pollen viability is essential for the genetic breeding, especially for controlled hybridizations. The aim of this study was to evaluate the effect of sucrose and of access on the viability of bacury pollen by in vitro germination. Five bacury accessions (BGB 6, BGB 11, BGB 48, BGB 32 and BGB 16) and five sucrose concentrations (0, 5, 7.5, 10, and 20%) were evaluated in a completely randomized design in a 5 x 5 factorial arrangement, with eight replications. In the majority GW-572016 research buy of the accessions, SBE-β-CD Microbiology inhibitor pollen germination in vitro reached a maximum

(71.1 to 63.0%) sucrose concentrations between 9.4 and 9.7% and from then fell dramatically until a percentage lower than 10% germination at a concentration of 20% sucrose. Showed good germination percentages (between 63.0 and 77.1%) for all accessions, except access BGB 16 did not reach 50%.”
“The attenuation of brain edema is a major therapeutic target after traumatic brain injury (TBI). Vasopressin (AVP) is well known to play a major role in the regulation of brain water content and vasoendothelial functions and to be involved in brain edema formation. Therefore, the aim of the current study was to analyze the antiedematous efficacy of a clinically relevant, nonpeptidic AVP V-1a and V-2 receptor antagonists. C57Bl6 mice were subjected to controlled cortical impact (CCI) and V-1a or V-2 receptors were inhibited by using the highly selective antagonists SR-49059 or SR-121463A either by systemic (intraperitoneal, IP) or intracerebroventricular (ICV) application. After 24 h, brain edema, intracranial pressure (ICP), and contusion volume were assessed. Systemically applied AVP receptor antagonists could not reduce secondary lesion growth.

All fracture surfaces were examined under the SEM. Results were analyzed nonparametrically with alpha = 0.05. Results: Under the mode of load applications in this study, TF had the lowest and FlexMaster the highest torsional resistance among the groups (p < 0.05). Scanning electron microscopy examination revealed a typical pattern of torsional fracture for TF, RaCe,

and ProTaper that was characterized by circular abrasion marks and skewed dimples near the center of rotation. In addition to these marks, Helix and FlexMaster presented a selleck compound rough, torn-off appearance. Conclusion: It was concluded that files of same cross-sectional design may exhibit different resistance to fracture probably as a result of the manufacturing process. (J Endod 2010;36:1200-1204)”
“Congenital multiple clustered dermatofibroma (MCDF) is a rare, idiopathic, benign tumor presenting at birth as an asymptomatic hyperpigmented

patch that is stable until puberty, at which time it enlarges and develops papules. Ultimately, MCDF appears to follow a stable, benign course. We present a case of a 12-year-old girl with congenital MCDF. To our knowledge, this is only the third reported case of congenital presentation of MCDF and the only case featuring atrophoderma-like KU-57788 mouse depression.”
“Objectives: To estimate the prevalence of obsessive-compulsive symptoms (OCS) and disorder (OCD) among adolescents and to describe OCD characteristics according to gender. Methods: Participants were selected by cluster sampling at seven high-schools in southern Brazil. In the first stage, 2,323 students were screened for OCS; in the second

stage, adolescents scoring bigger than = 21 on the OCI-R scale were individually interviewed. OCD diagnosis was established using a semi-structured interview (Schedule for Affective Disorders and Schizophrenia for School Aged Children: Present and Lifetime Version – K-SADS-PL). Results: The past-month estimated prevalence of OCS was 18.3%, and the point estimated prevalence of OCD, 3.3%. Girls showed higher scores (OCS: 24.8 vs. 14.4%; OCD: 4.9 vs. 1.4%; p smaller than 0.001). Only 9.3% of OCD adolescents had been diagnosed and 6.7% received treatment. The most frequent/severe DY-BOCS dimensions were miscellaneous (86.7%; mean score 6.3 +/- 3.8) and symmetry (85.3%; selleck products 5.9 +/- 3.8). Female OCD adolescents predominantly showed depression (p = 0.032), and male adolescents, tic disorders (p = 0.006). Conclusions: OCD is underdiagnosed in adolescents, and few are treated. Future studies should investigate the relationship between OCS and the onset of OCD.”
“In 2001-2005 we sampled permanently marked big brown bats (Eptesicus fuscus) at summer roosts in buildings at Fort Collins, Colorado, for rabies virus neutralizing antibodies (RVNA). Seroprevalence was higher in adult females (17.9%, n = 2,332) than males (9.4%, n = 128; P = 0.007) or volant juveniles (10.2%, n = 738; P smaller than 0.0001).

Furthermore, the deviations of the absolute VAS values in individual patients for each descriptive pain term were significantly smaller with PAULA than with the standard VAS.”
“The infiltration of human myometrium and cervix with leukocytes and the formation of a pro-inflammatory environment within the uterus have been associated with the initiation of both term and preterm parturition. The mechanism regulating the onset of this pro-inflammatory cascade is not fully elucidated. We demonstrate that prokineticin 1 (PROK1) is up-regulated in human myometrium and

placenta during labor. The expression of Protein Tyrosine Kinase inhibitor PROK1 receptor remains unchanged during labor and is abundantly expressed in the myometrium. Gene array analysis identified 65 genes up-regulated by PROK1 in human myometrium, mainly cytokines and chemokines, including IL-1, chemokine C-C motif ligand 3, and colony-stimulating factor 3. In addition, we demonstrate that PROK1 increases the expression of chemokine C-C motif ligand 20, IL-6, IL-8, prostaglandin

synthase 2, and prostaglandin HSP inhibitor drugs E, and F, secretion. The treatment of myometrial explants with 100 ng/naL of lipopolysaccharide up-regulates the expression of PROK1, PROK1 receptor, and inflammatory mediators. The infection of myometrial explants with lentiviral selleck screening library microRNA targeting PROK1, preceding treatment with lipopolysaccharide, reduces the expression of inflammatory genes. We propose that PROK1 is a novel inflammatory mediator that can contribute to the onset of human parturition at term and partially mediate premature onset of inflammatory

pathways during bacterial infection. (Ant J Patbol 2011, 179:2709-2719; DOI: 10.1016/j.ajpatb.2011.08.029)”
“A multigene data set (12S, 16S, and COI mitochondrial DNA; 18S and 28S nuclear DNA) was analyzed by Bayesian inference to estimate the phylogeny of a sample of the clitellate family Enchytraeidae (86 species representing 14 nominal genera). Monophyly, as well as a basal dichotomy, of the family Enchytraeidae obtained maximum support, with one clade containing Hemienchytraeus and Achaeta, the other the remaining 12 genera analysed. The latter group is basally resolved in several well-supported clades. Lumbricillus and Crania are closely related. Bryodrilus, Oconnorella, Henlea and two species of Marionina (M. cf. riparia, and M. communis) form a well-supported clade. Cognettia is sister to Stercutus, and Cernosvitoviella sister to Mesenchytraeus, and the four together appear to be a monophyletic group. A large part of the taxonomically problematic Marionina appears to be a group not closely related to the type species (M. georgiana), and this group also includes Enchytronia.

The reduction in HDAC2 appears to be secondary to the increased oxidative and nitrative click here stress in COPD lungs. Antioxidants and inhibitors of nitric

oxide synthesis may therefore restore corticosteroid sensitivity in COPD, but this can also be achieved by low concentrations of theophylline and curcumin, which act as HDAC activators.”
“Background: Bronchial thermoplasty is a novel technique designed to reduce an airway’s ability to contract by reducing the amount of airway smooth muscle through controlled heating of the airway wall. This method has been examined in animal models and as a treatment for asthma in human subjects. At the present time, there has been little research published about how radiofrequency (RF) energy and heat is transferred to the airways of the

lung during bronchial thermoplasty procedures. In this manuscript we describe a computational, theoretical model of the delivery of RF energy to the airway wall.\n\nMethods: An electro-thermal Y-27632 mechanism of action finite-element-analysis model was designed to simulate the delivery of temperature controlled RF energy to airway walls of the in vivo lung. The model includes predictions of heat generation due to RF joule heating and transfer of heat within an airway wall due to thermal conduction. To implement the model, we use known physical characteristics and dimensions of the airway and lung tissues. The model predictions were tested with measurements of temperature, impedance, energy, and power in an experimental canine model.\n\nResults: Model predictions of electrode temperature, voltage, and current, along with tissue impedance and delivered energy were compared

to experiment measurements and were within +/- 5% of experimental selleck chemical averages taken over 157 sample activations. The experimental results show remarkable agreement with the model predictions, and thus validate the use of this model to predict the heat generation and transfer within the airway wall following bronchial thermoplasty.\n\nConclusions: The model also demonstrated the importance of evaporation as a loss term that affected both electrical measurements and heat distribution. The model predictions showed excellent agreement with the empirical results, and thus support using the model to develop the next generation of devices for bronchial thermoplasty. Our results suggest that comparing model results to RF generator electrical measurements may be a useful tool in the early evaluation of a model.”
“The global geographic distribution of biodiversity and biomes is determined by species-specific physiological tolerances to climatic constraints. Current vegetation models employ empirical bioclimatic relationships to predict present-day vegetation patterns and to forecast biodiversity changes and biome shifts under climatic change.

Although

the intestine generally absorbs oxalate from dietary sources and can contribute as much as 50% of urinary oxalate, enteric oxalate elimination plays a significant role when renal function is compromised. YH25448 While the mechanistic basis for these changes in the direction of intestinal oxalate movements in chronic renal failure involves an upregulation of angiotensin II receptors in the large intestine, enteric secretion/excretion of oxalate can also occur by mechanisms that are independent of angiotensin II. Most notably, the commensal bacterium Oxalobacter sp. interacts with the host enterocyte and promotes the movement of oxalate from the blood into the lumen, resulting in the beneficial effect of significantly lowering urinary oxalate excretion. Changes in the passive permeability

of the intestine, such as in steatorrhoea and following gastric bypass, also promote oxalate absorption and hyperoxaluria. In summary, this report highlights the two-way physiological signalling between the gut and the kidney, which may help to alleviate the consequences of certain kidney diseases.”
“Nonhuman primates are useful animal models for the study of human diseases. However, the number of established cell lines from nonhuman Selleck 3-deazaneplanocin A primates is quite limited compared with the number established from other experimental animals. The establishment of nonhuman primate cell lines would allow drug testing on those cell lines before moving experiments into primates. In this

study, we established nonhuman primate primary cell lines by introducing the genes for CDK4R24C, cyclin D1, and hTERT. These cell lines proliferated more rapidly than primary cells and bypassed cellular senescence. Karyotype analysis showed that the chromosome patterns were intact in the immortalized cell lines. Furthermore, we showed that the expression of introduced Tyrosine Kinase Inhibitor Library genes could be precisely controlled through the Tet-Off system with the addition of doxycycline. The present study shows that introduction of the CDK4R24C, cyclin D1, and hTERT genes are effective methods of establishing nonhuman primate cell lines. (C) 2014 Wiley Periodicals, Inc.”
“The adaptor protein p66Shc regulates intracellular oxidant levels through the modulation of a forkhead-related transcription factor (FOXO3a). The genetic ablation of p66(Shc) (p66(Shc-/-)) renders mice resistant to oxidative stress and p53-dependent apoptosis. We investigated whether p66(Shc) ablation in mice modifies lung cellular and molecular responses to cigarette smoke (CS) exposure. No differences between wild type (WT) and p66(Shc-/-) mice were observed in terms of inflammation and oxidant burden after acute CS exposure; however, p66(Shc) ablation modifies specific features of chronic inflammation induced by repeated exposure to CS.

The low bias in summer maximum GPP at the semi-arid site could be due to seasonal response of V-cmax to temperature and precipitation while overestimated spring values at the mesic site could be due to response of V-cmax to temperature and day length.”
“PURPOSE: To analyze the relationship of strength, muscular balance, and atrophy with pain and function in patients with degenerative spondylolisthesis. STUDY DESIGN: Transversal, descriptive, and observational. PATIENTS AND METHODS: Institutional review board approval was obtained for this study. Twenty

six patients ages 50 years and older, with degenerative spondylolisthesis at L4-L5. Measurements included Pain Visual Analogue Scale scores (VAS), Oswestry Disability GDC-0973 price Index scores (ODI), and isokinetic trunk testing; assessment of multifidus atrophy and spinal stenosis was performed by Magnetic Resonance Imaging (MRI). STATISTICS: Statistical analysis was performed using SPSS version 17.0 software for Windows. Pearson’s correlation was used to ascertain the check details correlation between variables. ANOVA with analysis of covariance was used to determine the correlation between the remainder variables. Significance was set at p smaller than 0.05. RESULTS: Of the 26 patients studied, with an average age of 60.23 +/- 7.6 years, 20 had grade I spondylolisthesis

and 6 were grade II. Correlation between the ODI scores and spondylolisthesis grading was significant (r = 0.576, p =

0.005); correlation between agonist/antagonist ratio in the isokinetic test (predominant extensor muscles over flexors) with the ODI scores was KU-57788 mouse also significant (r = 0.446, p = 0.02), regardless of spinal stenosis. No correlation was found between functionality and pain with strength or multifidus atrophy. CONCLUSION: Muscle trunk imbalance with predominance of extensor over flexor muscles is associated with functional disability. Rehabilitation programs should be designed to improve muscle balance rather than muscle strength alone.”
“In eukaryotic cells, regulated vesicular trafficking is critical for directing protein transport and for recycling and degradation of membrane lipids and proteins. Through carefully regulated transport vesicles, the endomembrane system performs a large and important array of dynamic cellular functions while maintaining the integrity of the cellular membrane system. Genetic studies in yeast Saccharomyces cerevisiae have identified approximately 50 vacuolar protein sorting (VPS) genes involved in vesicle trafficking, and most of these genes are also characterized in mammals. The VPS proteins form distinct functional complexes, which include complexes known as ESCRT, retromer, CORVET, HOPS, CARP, and PI3K-III. Little is known about the orthologs of VPS proteins in insects.
