Annual home ranges of neighboring groups overlapped substantially, as

predicted (baboons are considered non-territorial), but home ranges overlapped less when space use was assessed over shorter time scales. Moreover, neighboring groups were in close spatial proximity to one another on fewer days than predicted by a null model, suggesting an avoidance-based spacing pattern. At all time scales examined (monthly, biweekly, and weekly), time spent in overlap areas was greater during time periods when groups fed on evenly 3-MA inhibitor dispersed, low-quality foods. The percent of fertile females in social groups was negatively correlated with time spent in overlap areas only during weekly time intervals. This suggests that broad temporal changes in ecological resources are a major predictor of how intensively overlap areas are used, and groups modify these ecologically driven spacing patterns at short time scales based on female reproductive status. Together, these findings offer insight into the economics of territoriality by highlighting the dynamics of spacing patterns at differing time scales.”
“Objective To review the current status and progress on pig islet xenotransplantation. Data sources Data used in this review were mainly from English

Selleckchem Danusertib literature of Pubmed database. The search terms were “pig islet” and “xenotransplantation”. Study selection The original articles and critical reviews selected were relevant to this review’s theme. Results Pigs are suggested to be an ideal candidate for obtaining available islet cells for transplantation. However, the potential clinical application of pig islet is still facing challenges PND-1186 including inadequate

yield of high-quality functional islets and xenorejection of the transplants. The former can be overcome mainly by selection of a suitable pathogen-free source herd and the development of isolation and purification technology. While the feasibility of successful preclinical pig islet xenotranplantation provides insights in the possible mechanisms of xenogeneic immune recognition and rejection to overwhelm the latter. In addition, the achievement of long-term insulin independence in diabetic models by means of distinct islet products and novel immunotherapeutic strategies is promising. Conclusions Pig islet xenotransplantation is one of the prospective treatments to bridge the gap between the needs of transplantation in patients with diabetes and available islet cells. Nonetheless, further studies and efforts are needed to translate obtained findings into tangible applications.”
“Kala-azar or visceral leishmaniasis, found mostly throughout the Indian Subcontinent, East Africa, and Brazil, kills 20,000-40,000 persons annually.

These approaches require detection devices such as inductive loop detectors or traffic surveillance

cameras to be installed at various locations. Consequently, they are not appropriate for an emerging self-organizing vehicular traffic information system, where vehicles have to collect and process traffic information without relying on any click here fixed infrastructure. In this paper, we consider a few methods for estimating vehicle density based on the number of vehicles in the vicinity of the probe vehicle and the number of vehicles in a communication cluster.”
“Background and aim of the study: Hemodynamic function and clinical outcomes were compared between the bovine pericardial Edwards Perimount Magna (EPM) and the porcine Medtronic Mosaic Ultra U0126 (MMU) aortic valve prostheses.\n\nMethods: Between January 2003 and June 2007, a total of 227 consecutive patients was prospectively enrolled, and received either the EPM (n = 125) or the MMU (n = 102) aortic valve prosthesis. The primary study end-point was the mean transvalvular gradient after surgery, at discharge and at six months follow up, as measured echocardiographically. The secondary study end-points were 30-day mortality and major adverse cardiac events (MACEs).\n\nResults: The intraoperative transvalvular mean pressure gradients were 9.4 +/- 4.6 mmHg in the EPM group compared to 17.7 +/- 6.7 mmHg in the MMU group (p <0.001),

and these remained essentially unchanged at hospital discharge (11.2 +/- 4.2 mmHg versus 19.1 +/- 6 mmHg; p <0.001) and at six months’ follow up (10 +/- 5 mmHg versus 20 +/- 7 mmHg; p <0.001). A multivariable risk-adjusted analysis of covariance revealed the MMU valve (p <0.0001) to be strongly associated with elevated postoperative mean transvalvular gradients during the six-month follow up. In addition, renal insufficiency, concomitant valve surgery and reoperation were identified as being significantly

associated FG-4592 inhibitor with in-hospital mortality (OR 3.3, 95% CI 1.3-8.1; OR 3.7, 95% CI 1.4-9.8; OR 3.3, 95% CI 1.1-10.2, respectively) and major adverse cardiac events (OR 2.2, 95% CI 1.0-4.7; OR 3.7, 95% CI 1.7-8.2; OR 2.7, 95% CI 1.1-7.2, respectively). To further control for selection bias, the propensity score was computed based on the major risk factors of 12 patients. An analysis of covariance model, adjusted for the propensity score, also confirmed the MMU prosthesis to be strongly associated with elevated mean transvalvular gradients during the six-month follow up period (p <0.0001).\n\nConclusion: The study results clearly demonstrated a favorable hemodynamic function as shown by lower transvalvular gradients of the bovine pericardial Edwards Perimount Magna compared to the porcine Medtronic Mosaic Ultra aortic valve prosthesis.”
“We assess the asymptotic bias of estimates of exposure effects conditional on covariates when summary scores of confounders, instead of the confounders themselves, are used to analyze observational data.

Results: Our cohort included 334,123 GDC-0973 patients across 122 hospitals and 168 ICUs. Unadjusted AC usage rates remained constant (36.9% [2001] vs. 36.4%

[2008]; P = 0.212), whereas CVC use increased (from 33.4% [2001] to 43.8% [2008]; P smaller than 0.001 comparing 2001 and 2008); adjusted AC usage rates were constant from 2004 (35.2%) to 2008 (36.4%; P = 0.43 for trend). Surgical ICUs used both catheters most often (unadjusted rates, ACs: 56.0% of patients vs. 22.4% in medical and 32.6% in combined units, P smaller than 0.001; CVCs: 46.9% vs. 32.5% and 36.4%, P smaller than 0.001). There was a wide variability in AC use across ICUs in patients receiving mechanical ventilation (median [interquartile range], 49.2% [29.9-72.3%]; adjusted median odds ratio [AMOR], 2.56), vasopressors (51.7% [30.8-76.2%]; AMOR, 2.64), and with predicted mortality of 2% or less (31.7%

[19.5-49.3%]; AMOR, 1.94). There was less variability in CVC use (mechanical ventilation: 63.4% [54.9-72.9%], AMOR, 1.69; vasopressors: 71.4% (59.5-85.7%), AMOR, 1.93; predicted mortality of 2% or less: 18.7% (11.9-27.3%), AMOR, 1.90). Conclusions: Both ACs and CVCs are common in ICU patients. VEGFR inhibitor There is more variation in use of ACs than CVCs.”
“Pain has been promoted as the fifth vital sign for a decade, but there is little empirical evidence to suggest that doing so has affected the care of individuals suffering pain. This was a three-stage audit of pain assessment in one large teaching hospital in the Northwest of England. Stage one measured

the baseline pain assessment activity on surgical and medical wards and identified that the pain assessment tool was not visible to nurses. Stage two redesigned the patient observation charts held at the end of the bed and piloted two versions for clinical utility. Version 2 which had pain assessment alongside the early warning score was adopted and introduced throughout the hospital. Stage three audited pain assessment and management 8 months after the introduction of the new charts. Pain was assessed more regularly at the stage three audit than at the Selleck BKM120 baseline audit. On average, pain was assessed alongside other routine observations 70% of the time across surgical and medical wards. Medical wards appeared to improve their pain assessment using the philosophy of pain being the fifth vital sign better than surgical wards, because they assessed pain alongside routine observations in bigger than 90% of cases. Stage three identified that where a high pain score was recorded, analgesia was delivered in the majority of cases (88%). Introducing the philosophy of pain as the fifth vital sign and making pain assessment more visible on the patient observation chart improved the uptake of pain assessment. Pain management strategies were stimulated when high pain scores were identified.

5-mm LCP

Reconstruction Plate; 3.5-mm LCP Superior Clavicle Plate; 3.5-mm LCP Superior Anterior Clavicle Plate; Synthes, Inc, West Chester, Pennsylvania). Specimens were tested for stiffness in axial torsion and cantilever bending and then loaded to failure in 3-point bending. Data were analyzed using 2-way analysis of variance and Tukey’s test (P smaller than .05). No significant Veliparib cost differences were found between unicortical and bicortical fixation in failure load, cantilever bending, and cross body stiffness. Bicortical fixation was significantly stiffer than unicortical fixation in torsion only for the same plates. Significant differences also existed between plates in torsion. Unicortical locked plate fixation may be a reasonable option in the treatment of displaced midshaft clavicle fracture fixation to avoid complications associated with posteroinferior hardware penetration following clavicle fracture fixation based on the biomechanical performance of these constructs. However, it remains unclear whether these differences will be clinically significant.”
“To

investigate the expression of TSPAN1 (Gene ID: 10103), Ki67 and CD34 in gastric carcinomas and the clinicopathological AZD9291 order significance, the expression of TSPAN1, Ki67 and CD34 was detected in 86 cases of gastric carcinoma, paraffin-embedded

sections using an immunohistochernical method. The rates of overexpression of TSPAN1, Ki67 and CD34 in gastric carcinomas were 56.98%, 74.42%, and 62.79%, respectively. The overexpression of these markers was positively correlated with clinical stage and negatively correlated with survival rates (at 3 and 5 years). The overexpression of TSPAN1 and Ki67 was negatively IPI-549 PI3K/Akt/mTOR inhibitor correlated with carcinoma differentiation, and the overexpression of TSPAN1 and CD34 was positively correlated with infiltration and lymph node status of the tumor. Thus, overexpression of TSPAN1, Ki67 and CD34 in gastric cancer tissues is associated with development of the cancer. The detection of expression of TSPAN1, Ki67 and CD34 in gastric cancer may provide useful prognostic information for patients with the disease.”
“Both the monophyly and inter-relationships of the major annelid groups have remained uncertain, despite intensive research on both morphology and molecular sequences. Morphological cladistic analyses indicate that Annelida is monophyletic and consists of two monophyletic groups, the clitellates and polychaetes, whereas molecular phylogenetic analyses suggest that polychaetes are paraphyletic and that sipunculans are crown-group annelids.

\n\nConclusion: Acute (60 minutes) or longer duration (2 years) exposure of murine brains to mobile telephone RF fields did not produce any microglial activation detectable by Iba1 immunostaining.”
“Four new metabolites, including three new oblongolides named C1, P1, and X1 (1-3) and 6-hydroxyphomodiol (10), along with eight known compounds – oblongolides B (4), C (5), D (6), O (7), P (8) and U (9), (3R,4aR,5S,6R)-6-hydroxy-5-methylramulosin (11), and (3R)-5-methylmellein (12) – were isolated from the endophytic fungal strain Phomopsis sp. XZ-01 of Camptotheca acuminate.

Their structures were elucidated by spectroscopic analyses, including H-1- and C-13-NMR, 2D NMR (HSQC, HMBC, H-1-H-1 COSY and NOESY) and HR-FT-MS. Cytotoxic activities of these compounds were evaluated. Some of them showed weak selective activities.”
“Objective: To evaluate the reporting quality of key methodological selleckchem items of randomized control trials (RCTs) in 55 of the highest ranked journals.\n\nStudy Design and Setting: A list of the highest top ranked journals was identified, and a search for detecting RCTs in those journals

was made. Two hundred sixty four journals were screened and 55 of them were identified having at least one RCT. Three RCTs were randomly selected a priori from each journal; 148 RCTs were finally included. RCTs were assessed by two reviewers using the Consolidated Standards of Reporting Trials (CONSORT) statement.\n\nResults: Only 11 (8%) RCTs had all items adequately reported. In addition, 36% of RCTs reported that the study Thiazovivin was registered in any trial registry. We found a significant difference in the quality of reporting for baseline characteristics,

recruitment, participant’s flow, and randomization implementation between those studies having reported the registration of their RCT in a trial registry and those that have not. Adherence to key methodological items of the CONSORT statement was as follows: sample size determination (60%), sequence generation (49%), allocation concealment (40%), and blinding LY2090314 order (25%).\n\nConclusions: Reporting of varied CONSORT items remains suboptimal. Registration in a trial registry was associated with improved reporting. Further efforts to enhance RCT registration could contribute to this improvement. (C) 2010 Elsevier Inc. All rights reserved.”
“Traditional macro and micro-electroporation devices utilize facing electrodes, which generate electric fields inversely proportional to their separation distance. Although the separation distances in micro-electroporation devices are significantly smaller than those in macro-electroporation devices, they are limited by cell size. Because of this, significant potential differences are required to induce electroporation.

79, = .94, and = .21, respectively). There was no significant difference in intraocular pressure change between the two groups during the follow-up period (P > .05).\n\nCONCLUSION: The current pilot study suggests that postoperative intravitreal injection of triamcinolone acetonide does not lead to better visual outcomes in patients undergoing pars plana vitrectomy for the treatment of idiopathic epiretinal membranes.”
“The 3-O-methylquercetin (3-MQ) is a flavonoid aglycone with important antioxidant, antiviral, and anticancer properties. The presence of 3-MQ in Nicotiana tabacum L trichomes is well known as the species’ response to environmental stress factors. Although 3-MQ has

been synthesized, its yield has been low and toxic by-products are formed that are difficult to separate. The present work reports the use of a simple method for extracting and isolating 3-MQ from organic www.selleckchem.com/products/lee011.html N. tabacum trichomes to make it available in higher amounts and greater purity for biological tests or pharmaceutical applications. The influence of some parameters related to plant variety, cultivation, extraction, and isolation on the yield of this flavonoid is herein reported. The highest 3-MQyield was obtained using ethanol in the extraction with a plant:solvent ratio of 1:15 (w/v) and 30-min extraction time.

Isolating 3-MQ from the ethanol extract was successfully performed from the corresponding dry residue by normal phase column chromatography (CC). The younger leaves of the Dark variety, cultivated in LY411575 molecular weight vase and collected at night, showed the highest 3-MQ yield. Thus, the Dark variety, ethanol extraction in a plant:solvent ratio of 1:15 (w/v) for 30 min, followed by CC isolation, were the best conditions for obtaining selleck chemical 3-MQ with over 90% purity and 60% yield. These excellent results may be useful as an alternative, promising use of tobacco. (C) 2014 The Authors. Published by Elsevier B.V. All rights reserved.”
“Recently, the new trend in the second-generation ethanol industry is to use mild pretreatments, in order to reduce costs and to keep higher content of hemicellulose in the biomass. Nevertheless, a high enzyme dosage

is still required in the conversion of (hemi)cellulose. The interaction between cellulases and xylanases seems to be an effective alternative to reduce enzyme loading in the saccharification process. At first, to evaluate the synergism of xylanases on bagasse degradation, we have produced two xylanases from glycoside hydrolase family 10 (GH10) and three xylanases from glycoside hydrolase family11 (GH11),from two thermophilic organisms, Thermobifida fusca and Clostridium thermocellum, and one mesophilic organism, Streptomyces lividans. Peracetic acid (PAA) pretreated bagasse was used as substrate. The combination of XynZ-C (GH10, from C. thermocellum), and XlnB (GH11, from S. lividans) presented the highest degree of synergy after 6 h (3,62).

These findings show that modulation of targets other than thioredoxin contribute to the effects of IV-2 on proliferating cells.”
“Heifers managed under pastoral conditions are at risk from Streptococcus uberis mastitis infections at calving. A total of 397 heifers from six farms around New Zealand were enrolled LGX818 in a study to identify and enumerate S. uberis on teat-ends

of heifers in the peri-partum period, and to understand the effect of teat-spraying in the pre-calving period on the prevalence and incidence of S. uberis mastitis post-calving. Heifers were randomly assigned to Control or Sprayed groups. Sprayed heifers were teat-sprayed once, three times a week (Monday, Wednesday and Friday) with a commercial iodine-based teat sanitizer. starting at 3 weeks prior to calving and ending at day of calving. Across three farms, all glands of cows in both groups were sampled at calving to determine

S. uberis intra-mammary infection (IMI) prevalence. For all farms, clinical mastitis (CM) cases detected during the week after calving were sampled AZD0530 mouse and submitted for bacteriological analysis. Swabbing of teat-ends of 54 heifers from one farm showed that heifers had a pre-existing S. uberis contamination averaging 610 colony-forming units per swab (cfu/swab), at 3 weeks prior to calving. At calving, teat-end contamination was 560 cfu/swab for Sprayed heifers and 1775 cfu/swab for Control heifers. Two weeks after calving, teat-end contamination was similar between both groups, at 30 cfu/swab. The prevalence of S. uberis IMI was significantly lower in the Sprayed (3.5%

glands) vs. the Control (7.4%) heifers in the first week after calving. There was a trend for Sprayed heifers (3.6% heifers) to have a lower incidence of S. uberis CM compared with Control heifers (7.4% heifers). It find more is concluded that teat-spraying in the dry period is a management option that could contribute to controlling heifer S. uberis mastitis in the transition period.

“Background. The purpose of our study was to review the role of reconstructive surgery in the management of pediatric oncology patients and to assess patients’ outcomes, including functional status.\n\nMethods. We evaluated 177 children with cancer who underwent reconstructive surgery at our institution between 1999 and 2008.\n\nResults. The mean age was 12.1 years, and the mean follow-up duration was 27.3 months. The most common tumor pathology was sarcoma (49.7%), and the most common reconstruction site was the head and neck (41.8%). Nearly half of all patients underwent preoperative (44.1%) and/or postoperative (45.8%) chemotherapy. Immediate reconstruction was performed in 84.7% of patients. Free tissue transfer (33.9%) was the most common form of reconstruction, and the fibula flap (58.4%) was the most common free flap used. Additional surgery (for any reason) was required in 41.8% of patients. In general, functional outcomes were excellent: 78.

The mean preoperative VAS score was 8.21 and the mean postoperative VAS score was 2.66 (P < 0.05). The mean preoperative kyphotic angle for the 11 individuals with the thoracic or thoracolumbar burst fractures was 24.6 and the mean preoperative lordotic angle for the 3 individuals with lumbar burst fractures was 10.6. The corresponding values at 12 months postsurgery were 17.1 and

13.6.\n\nConclusion. This single-stage posterior approach for acute thoracic and lumbar burst fractures offers some advantages over the classic combined anterior-posterior approach. The results from this small series suggest that a single-stage posterior approach should be considered in select cases.”
“A total of 42 ejaculates were this website used in the experiment;

six ejaculates per stallion, obtained from seven Pure Spanish stallions (PRE), were split and frozen in freezing media with different concentrations and combinations of cryoprotectant (CPA): (i) Caceres (skim milk based extender) containing 2.5% glycerol (2.5GL), (ii) Caceres containing 1.5% glycerol and 1.5% dimethylformamide (1.5%GL1.5%DMFA), (iii) Caceres extender supplemented with 1.5% glycerol and 2.5% dimethylformamide (1.5%GL2.5%DMFA) and (iv) Caceres extender supplemented with 4% dimethylformamide (4%DMFA). After at least 4 weeks of storage ERK inhibitor supplier in liquid nitrogen (LN), straws were thawed and semen analysed by computer-assisted sperm analysis and flow cytometry (membrane lipid architecture (Merocyanine 540), integrity and sublethal damage (YoPro-1) and mitochondrial GSK2126458 mw membrane potential (JC-1)). After thawing, better results were observed in samples frozen in 4%DMFA or in combinations of 1.5%GL2.5%DMFA, in fact total motility increased by 16% in the 4%DMFA group compared to 2.5%GL (P < 0.05). Also, there was an increment in the percentage of progressive motile sperm in the 1.5%GL2.5%DMFA group (9.8% 2.5GL vs 19% in the 1.5%GL2.5%DMFA group p < 0.05); also, samples frozen in the 4%DMFA group had more intact (YoPro-1 negative) sperm

post-thawing, 29.3% in 2.5%GL vs 36.7% in 4%DMFA group (p < 0.05). Membrane lipid architecture was not affected by any of the cryoprotectants tested, while samples frozen in 4%DFMA had a lower percentage of mitochondria with lower membrane potential. It is concluded that DMFA improves the outcome of cryopreservation of stallion spermatozoa mainly reducing sublethal cryodamage.”
“BACKGROUND: The N-terminal fragment of pro-brain type natriuretic peptide (NT-proBNP) is an established biomarker for cardiac failure.\n\nOBJECTIVE: To determine the influence of preoperative serum NT-proBNP on postoperative outcome and mid-term survival in patients undergoing coronary artery bypass grafting (CABG).\n\nMETHODS: In 819 patients undergoing isolated CABG surgery preoperative serum NT-proBNP levels were measured.

The CRF receptor type 1 (CRFR1) is considered

the primary and canonical target of CRF signaling, and systemically it plays an essential role in coordinating the body-wide stress response via activation of the hypothalamic-pituitary-adrenal (HPA) axis. Here, we describe an essential role for CRFR1 in auditory system development and function, and offer the first description of a complete HPA equivalent signaling system resident within the cochlea. To reveal the role of CRFR1 activation in the cochlea, we have used mice carrying a null ablation of the CRFR1 gene. CRFR1(-/-) mice exhibited elevated auditory thresholds at all frequencies tested, indicating reduced sensitivity. Furthermore, our results suggest that CRFR1 has a developmental role affecting inner hair cell QNZ NF-��B inhibitor morphology and afferent and efferent synapse distribution. Given the role of HPA signaling in maintaining local homeostasis in other tissues, the presence of a cochlear HPA signaling system suggests important roles for CRFR1 activity in setting cochlear sensitivity, perhaps both neural and non-neural

mechanisms. These data highlight the complex pleiotropic mechanisms modulated by CRFR1 signaling in the cochlea.”
“Objective: To identify trajectories of behavioral adjustment from age 6 through 14 years for youth placed in early foster care, and to examine links between trajectories and early cognitive ability and social competence, caregiver stability, and frequency, timing, and type of maltreatment. Method: Participants JNK-IN-8 price were 279 youth from the Southwest site of the Consortium for Longitudinal Studies of Child Abuse and Neglect (LONGSCAN). All youth had spent at least 5 months in out-of-home care before age 4 years because of substantiated reports of maltreatment. Behavioral adjustment selleck products was assessed using caregiver

reports on the Child Behavior Checklist at ages 6, 8, 10, 12, and 14. Cognitive ability and social competence were assessed at age 6. Caregiver stability was recorded every 2 years from age 6 through 14 years and summed. Child protective services (CPS) maltreatment reports were coded for type and frequency. Results: Growth mixture modeling identified three internalizing trajectories: stable adjustment (66.7%), mixed/decreasing adjustment (25.4%), and increasing adjustment (7.9%). Four externalizing trajectories were identified: stable adjustment (46.6%), mixed adjustment (28.7%), increasing adjustment (8.2%), and stable maladjustment (16.5%). Trajectories of stable or increasing adjustment were predicted by social competence, cognitive ability, placement stability, and low frequency of physical abuse from ages 6 through 14. Conclusions: Many youth who have spent time in early out-of-home care evidence stable, long-term positive behavioral adjustment.

Ultrasound agreed with panorex x-rays in 6 (86%) of 7 cases. One case where US disagreed with x-rays was evaluated by dentistry consultants; and incision and drainage were performed, confirming the presence of an abscess. An x-ray diagnosis of periapical abscess was made in 12 (63%) of 19 see more patients. Ultrasound agreed with panorex x-ray in 10 (83%) of 12 cases. In 1 of the 2 cases where US disagreed with panorex x-rays, x-ray abnormalities were reported on the nonsymptomatic side. The other

patient was given antibiotics and recommended outpatient follow-up. Follow-up information was not available to further confirm the presence of an abscess. Assuming that the patient who was lost to follow-up had dental abscess, the sensitivity and specificity of US in diagnosing a dental abscess were 92% and 100%, respectively.\n\nConclusions: Bedside US is nonionizing, is readily available, and can provide an alternative to panorex x-rays in the evaluation of a dental abscess in ED.

“Noninvasive imaging of the coronary arteries using multicletector CT (MDCT) represents one of the most promising diagnostic imaging advances in contemporary cardiology. GSK1120212 in vivo This challenging application has driven

a rapid and impressive advancement in CT technology over the past 10 years; leading to increased spatial and temporal resolution, decreased scan times and substantial reductions in radiation dose. Recent technological improvements have not only improved the status of CT coronary angiography but have also enabled new functional myocardial applications that are gaining a foothold in clinical practice as adjuncts or replacements for conventional coronary angiographic studies. Wide-detector CT designs along with prospective ECG-triggered protocols have opened the possibility of performing multiple complementary myocardial

In this Review, we discuss recent technical developments in cardiac MDCT and outline newly enabled noncoronary cardiac applications including viability assessment, myocardial perfusion and molecular imaging.”
“Microarray techniques have revolutionised genomic research by making it possible to monitor the expression of thousands of genes in parallel. The Fuzzy C-Means (FCM) method is an efficient clustering approach devised for microarray data analysis. However, microarray data contains noise, which would affect clustering results. In this paper, we propose to combine the FCM method with the Empirical Mode Decomposition (EMD) for clustering microarray data to reduce the effect of the noise. The results suggest the clustering structures of denoised microarray data are more reasonable and genes have tighter association with their clusters than those using FCM only.
