2000), Afatinib order PLA2 clone A85/9-4 (Kanashiro et al., 2002), and hemorrhagin (Zn-metalloproteinase) clone 59/2-E4 (Barros et al., 1998) of B. atrox snake venom were cultured with DMEN-F12 medium, supplemented with 10% FCS and 10 μg/mL gentamicin. Each culture was expanded and 1 × 106 cells were inoculated i.p. in adult BALB/c mice previously i.p. injected with 400 μl mineral oil. After ten days, mice were euthanized by CO2 inhalation, and the ascitic fluid was collected by abdominal puncture. Monoclonal antibodies were purified with caprylic acid followed by ammonium sulfate precipitation (Steinbuch et al., 1970). Briefly, ascitic fluid was diluted 1:3 in 60 mM sodium acetate buffer, pH 4.0, and 0.4 mL caprylic acid was added under agitation for 30 min at room temperature for each 10 mL of ascitic fluid. The mixture was centrifuged at learn more 5000× g for 1 h and the supernatant was collected. After centrifugation, the pH of supernatant was adjusted to 7.0 and ammonium sulfate was added under agitation to achieve a 45% concentration (w/v), and the mixture allowed to stand at 4 °C overnight. Precipitates were recovered by centrifugation at 5000× g for 30 min, redissolved

and dialyzed against saline 0.9%, and immunochemically analyzed by SDS-PAGE and Western blot. Samples of dialyzed mAbs were subjected to 12% polyacrylamide gel electrophoresis (SDS-PAGE), according to the method described by Laemmli (1970) with modifications. The samples were dissolved in sample buffer (0.5 M Tris–HCl buffer, pH 6.8 plus 10% SDS, 10% 2-β-mercaptoethanol, and 0.5% bromophenol blue dye), boiled at 100 °C, loaded on 12% polyacrylamide gel, and run at 150 v. Protein bands were stained with Coomassie brilliant blue and subjected to computerized densitometric analysis (Bozzo and Retamal, 1991). Western blot was performed, according to a previously described method (Towbin et al., 1979).

Binding ability of the purified mAbs to the respective antigen was evaluated by ELISA test, according to the methodology described by Almeida et al. (1998). Briefly, B. atrox venom (10 μg/mL) or enriched fraction click here of thrombin-like toxin (10 μg/mL) was diluted in 0.1 M carbonate/bicarbonate buffer (pH 9.6) and adsorbed to the ELISA plate. After a blocking step with gelatin, mAbs were diluted and added to wells. ELISA plates were incubated at 37 °C for 45 min followed by the addition of secondary antibody. The reaction was developed with o-phenylenediamine plus hydrogen peroxide, and color development was stopped with 50 μL 3 N H2SO4. Plates were read spectrophotometrically at 490 nm. Forty micrograms of myotoxic PLA2 from B. atrox venom, purified according to the method described by Kanashiro et al. (2002), were preincubated with 140 μg A85/9-4 mAb, and then aliquots of the mixtures were injected into the gastrocnemius muscle of five Swiss mice.

Novel developments include microspheres-enhanced thrombolysis for improved drug delivery and enhancement of microcirculation [5] and [6]. A recent pilot study has tested the feasibility of using an intra-arterial high-energy US catheter for recanalization [7]. Although many promising advances have been made in the field of sonothrombolysis, “diagnostic” transcranial US remains the only method that GDC-0980 mouse has been shown to be effective and safe. The aim of this review is to provide an

overview of confirmed evidence and perspectives on sonothrombolysis for the treatment of acute ischemic stroke (AIS). The thrombolytic effect of “diagnostic” transcranial US in acute intracranial occlusion was discovered more than 10 years ago at 3 stroke therapy centers, independently of each other. At the Center for Noninvasive Brain Perfusion Studies at the University of Texas-Houston Medical School, physicians

noticed that patients receiving continuous transcranial see more US monitoring for determination of rtPA-associated recanalization more frequently exhibited a favorable clinical course in comparison to patients without monitoring [8]. Based on these results, a randomized, multicenter clinical trial, known as the Combined Lysis of Thrombus in Brain Ischemia Using Transcranial Ultrasound and Systemic tPA (CLOTBUST) trial, was performed to study this effect. A similar effect was observed with TCCS in the stroke unit at the University of Lübeck, Germany [9] (Fig. 1). In contrast to the multicenter CLOTBUST trial, this monocenter, randomized study also included patients with contraindications to rtPA. In addition, neurologists at the University Hospital Selleck Nintedanib Ostrava, Czech Republic, observed a similar effect in patients with acute cerebral artery occlusion during examination with TCCS [10]. The CLOTBUST trial included a total of 126 patients with occlusion of the main segment of the stem or branches of the MCA. All subjects were treated with standard IV rtPA and were additionally

randomized for a 2-h insonation with transcranial Doppler (TCD). The primary endpoint (complete recanalization or substantial clinical improvement) was more frequently reached in the sonothrombolysis group (40%) than in the standard therapy group (30%). No significant differences were found in the clinical results obtained after 24 h and after 3 months. However, a clear tendency for functional independence after 3 months was detected in the sonothrombolysis group. The rate of symptomatic intracranial hemorrhage (sICH) was the same for each group (4.8%) [1]. Some limitations of the CLOTBUST trial were the inclusion of an inhomogeneous patient sample (MCA main stem and branch occlusions) and the definition of the primary endpoint. The US imaging of the thrombus, carried out with blind TCD sonography by means of a probe attached to the head, may also have been inadequate, particularly in branch occlusions or occlusions of the main stem without residual flow.

We accordingly investigated whether responses on the Short-Form CSQ were related to administration format. The EPZ015666 in vivo development of our new Short-Form CSQ was an iterative process involving three increasingly refined versions of the CSQ. These

versions are termed CSQ-13, CSQ-11, and CSQ-SF, and were administered to three separate sets of participants. A first convenience sample of 249 (160 women) adults with a mean age of 21.7 years (SD = 7.05, range = 17–58) completed the CSQ-13. A separate convenience sample of 390 (257 women) undergraduate students (mean age = 20.2 years, SD = 1.65, range = 17–32) then completed the CSQ-11. Finally, a new convenience sample of 278 adults (145 women) (mean age = 21.4 years, SD = 6.86, range = 18–62) completed the CSQ-SF. Of this sample, 193 participants (102

women), with a mean age of 20.4 years (SD = 4.25, range 18–55), went on to Akt inhibitor complete the Hospital Anxiety and Depression Scale (HADS: Zigmond & Snaith, 1983). Four weeks after the first testing session, 60 of the original participants (54 female), with a mean age of 19.6 years (SD = .85, range = 19–24), completed the CSQ-SF for a second time to investigate test–retest reliability. No incentive was offered for participation. The CSQ-13 and CSQ-SF were completed in paper-and-pen format; the CSQ-11 was completed in electronic format. To recruit the latter sample, a circular email was sent out to undergraduates from a wide range of degree programs at a British university, directing them to a website link. The only personal details requested for both formats were age and gender; participants were not screened for psychiatric disorders. The instructions and format of each scenario in the electronic version of the CSQ Montelukast Sodium were identical to those of the corresponding paper-and-pen version. In the administration of the third and final version (CSQ-SF), a sub-group of participants additionally completed the HADS (Zigmond & Snaith, 1983). This is a brief and psychometrically sound (Zigmond & Snaith, 1983) instrument to measure psychological distress. The HADS contains 14

items and consists of two subscales: anxiety and depression. Our shortening of the CSQ first focused on the requirement to write down a potential cause for each scenario. The named causes are not analyzed and play no role in determining participants’ scores on the CSQ. However, the named cause for each event is repeatedly mentioned in the questions that follow, making the wording of the item lengthy and complex (see Table 1 for an example). In our adaptation of the CSQ, participants were not required to write down a specific cause, but were simply directed to “Think carefully about the reason for [scenario] then answer the questions below”. Our second adaptation served further to simplify the wording of the individual questions.

N-[(3-trimethoxysilyl) propyl] EDTA trisodium salt (50% in water) was received from Gelest Inc., U.S.A. The water used throughout this work was of reagent grade produced by a Milli-Q water purification system. DMEM (Dulbecco’s modified Eagle’s medium), FBS (foetal bovine serum) and PenStrep (penicillin–streptomycin) were purchased from Biological Industries Inc. Fe3O4 nanoparticles were synthesized as described Selleck Z VAD FMK by Jana et al. [20]

with slight modifications. In a typical synthesis of iron–oleate complex, 2.55 g of iron chloride (FeCl3.6H2O) was dissolved in 100 ml of methanol and 11 ml of oleic acid under continuous stirring. Another solution prepared by dissolving 1.6 g of NaOH in 200 ml of methanol was added to the above solution in stirring condition. The observed brown precipitate of iron oleate was washed with methanol and dried under vacuum overnight to remove the solvent. 4.02 g of synthesized solid mass was dissolved in 30 ml of 1-octadecene at 70 °C to make stock solution. Thereafter, 10 ml of stock solution was mixed with 40 ml of 1-octadecene and 0.1 equiv. of oleic acid and the solution ATM/ATR inhibitor was heated to 280 °C for 30 min in an inert environment. When the reaction was complete, the mixture

was precipitated twice with ethanol. Resulting precipitate was re-dispersed in hexane for further use. Synthesized nanoparticles are stable in nonpolar solvents (such as hexane) and capped with nonpolar end groups on their surface. Oleic acid is widely used in Rapamycin ic50 the synthesis of iron oxide nanoparticles because it can form a dense protective monolayer, thereby, producing highly uniform and monodisperse

particles [6]. For the synthesis of iron oxide nanoparticles (INPs) suitable for biological applications, the hydrophobic surfactant coating needs to be replaced by a hydrophilic, biocompatible, and functional coating that allows controlled interaction of nanoparticles with biological species. The oleic acid on the particle surface was replaced with a COOH containing silane using a method reported by Palma et al. [21]. Once functionalized with a carboxylic group, nanoparticles were further functionalized using chitosan oligosaccharide method developed by López-Cruz et al. [22]. Amino group of chitosan oligosaccharide was covalently bonded with terminal carboxylic group of silane functionalized iron oxide nanoparticles through carbodiimide activation by the reaction of EDC and NHS [23]. TEM images were recorded on a JEOL 2100F TEM, operated at an accelerating voltage of 200 kV. Samples were prepared by adding 10 μl of the nanoparticles solution on 200-mesh carbon coated Cu grids. For the rapid counting of nanoparticles, TEM images were further processed by NIH Image J software [24]. Powder X-ray diffraction (XRD) studies were carried out through a Philips1820 advance diffractometer equipped with Ni-filtered Cu Kα radiation maintaining the scan rate of 0.24° per minute.

Arms are positioned in internal

rotation. The consequence of shoulder malposition and chest deformation is reduced breathing mobility Selumetinib in vivo in the physical examination. In the sitting position, there is a significantly posterior pelvis tilt. Additionally, there is no alternating movement of the arms ( Fig. 4). Range of motion and muscle strength of the cervical spine is reduced. This includes, in particular: extension, lateral bending, torsion to the left side, and muscle strength while bending forward, sideways, and to the left (3 in the Lovett scale) ( Table I). There is limited torsion movement in the thoracic spine as well. The observed abnormalities are mainly associated with paresis of the flexors, abductors, and external rotators of the shoulder, elbow flexors and with contractures as a result of muscular imbalance. X-ray shoulders showed no shoulder dislocation. There is not much literature data dealing with OBPP. Review of the literature revealed only a few bilateral brachial plexus injury cases reports [4]. Philpot et al. [9] presented a case report of symmetrical paralysis limited to the upper limbs with an intrauterine etiology, associated with Debendox (Bendection) and nitrofurantoin, which were

taken by the mother during the first months of pregnancy because of nausea and urinary tract infections. Papers on OBPP only refer to the incidence or etiology of this type of damage [1] and [6]. The risk factor for brachial plexus injury in this case Linsitinib mouse was breech presentation in labor. Caesarean section in high risk cases can reduce the possibility of this kind

of lesion. Al-Qattan [10] reported that the occurrence of OBPP in surgical termination of pregnancy is very rare. In turn, low Apgar score might be associated with muscular hypotension due to neonatal asphyxia. Weaker brachial plexus muscle stabilization also predisposes to lesion. Early correct recognition of injury is important for surgical or conservative treatment check details [7] and [10]. Diagnosis of OBPP in the newborn usually isn’t a problem, but in this case due to life threatening circumstances and uncertain outcome it was difficult to determine and was of secondary importance. This would explain the late diagnosis and late initiation of Vojta therapy, which should have begun in the second week after delivery. Neuropraxia injury diagnosed in the first examination, onset of minor movements in shoulders seen at 4 months of age and the improvement of neuromuscular transmission reported at 14 months of age provided a chance for overall spontaneous recovery without surgical intervention. In this type of injury in about 90% of individuals, we may expect improvement within the first 3 months of age [11]. Symptoms of paresis associated with neuropraxia disappear by then.

Sinograms were framed into 25 frames (6 × 10 seconds, 4 × 15 seconds, 2 × 30 seconds, 2 × 120 seconds, 1 × 180 seconds, 6 × 300 seconds, and 4 × 600 seconds) and reconstructed with an ordered subset expectation maximation (OSEM) two-dimensional iterative algorithm. Images were summed from 60 to 80 minutes, and volumes of interest were drawn over whole tumors with Inveon Research Workplace image analysis software 4.1 (Siemens Medical Solutions), using the CT template as an anatomic reference. Radioactivity uptake was calculated as the percentage of injected dose per gram tissue (%ID/g) in whole tumor. After PET/CT scans, mice were killed, tumors were collected,

and paraffin-embedded tumor sections were stained with antibodies raised against CA IX (ab15086; Abcam, Cambridge, UK, 1:8000), Glut-1

(GT12-A; Immune Diagnostics and Research, Hämeenlinna, Finland, 1:1000), and Hif-1α (610959; BD Transduction Laboratories, Franklin SB431542 Lakes, NJ, USA, 1:100). Immunostaining was performed as described previously [11]. The expressions of CA IX, Glut-1, and Hif-1α were visually analyzed from 10 different areas in each tumor section using a × 20 microscope objective. The percentage of positively stained tumor cells was counted, and staining intensity was described as weak (1), moderate (2), or strong (3). Each tumor was scored (range = 0-300) by multiplying the average intensity value by the average percentage of positively stained cells. Analyses were performed independently by two investigators (J.S. and K.K.). Digital autoradiography

was used to measure the Selleckchem Fluorouracil uptake of [18F]EF5 and [18F]FDG in cell lines grown on eight-well chamber slides (Nunc™, Thermo Scientific, Waltham, MA, USA) under normoxia and different time periods of hypoxia (1% O2). Four days before tracer incubation, cells were plated onto chamber slides in duplicate (two wells per cell line) and cultured under normal culturing conditions. Medium Cyclooxygenase (COX) was changed on the third day. Cells were seeded at various densities according to their growth rates to ensure that there would be equal amount of cells at the time of tracer incubation. On day 4, one chamber slide per time point was transferred to a hypoxia workstation (Invivo2; Ruskinn Technology Ltd, Pencoed, United Kingdom) at 24, 12, 6, 3, and 1 hour before the end of tracer incubation time. Chambers were removed, and slides were washed with phosphate-buffered saline before being incubated with [18F]EF5 or [18F]FDG for 60 or 30 minutes, respectively, in 50 kBq/ml Dulbecco’s modified Eagle’s medium ([18F]EF5) or physiological saline ([18F]FDG) under hypoxia. The workstation and all solutions used were stabilized in 1% O2 before the experiment. Control cells were incubated with tracers under normal culture conditions (normoxia, 0 hour). Cells were then washed with phosphate-buffered saline and fixed in 4% paraformaldehyde for 10 minutes at room temperature.

g. Meier 2006). According to Kjellström et al. (2011), precipitation increases during winter in the Nutlin-3a manufacturer north and decreases during summer in the south. However, the borderline migrates back and forth from a northerly position in summer to a southerly one in winter.

The precipitation increase is partly explained by increased zonality and partly by an amplification of the hydrological cycle, as Kjellström & Lind (2009) found. According to Kjellström et al. (2011), the explained variance based upon spatial variances of SLP and the mean absolute error for temperature and precipitation over land suggest that RCA3 driven with the GCMs Arpege, ECHAM5 (experiment ‘-r3’, for the description see Kjellström et al. 2011), HadCM3_ref and HadCM3_low perform best during the control period. However, in winter selleck products all GCM simulations are too zonal, thus affecting the quality of the other variables due to advection. Focusing on the atmospheric surface fields over sea, our analysis confirms the results by Kjellström et al. (2011). However, it is impossible to rank the models. Depending on the variable, the results are quite different. For instance, ECHAM5 and HadCM3_ref driven simulations showed the best SLP

and air temperature results, respectively, but none of the models is perfect for all variables. In addition to biases of Demeclocycline the large-scale circulation induced by the lateral boundary data, atmospheric surface variables over sea also suffer from biases of SST and sea ice data from the GCMs. Therefore, the results of RCA3 could be affected such that the gain

of the higher resolution in the RCM is compensated for by these biases. A quality assessment of atmospheric fields from RCA3 over the sea is more a validation of GCM results for the Baltic Sea than an evaluation of RCA3 performance. Hence, in this study the added value of the coupled atmosphere-ice-ocean model RCAO was investigated. Because of the computational burden we performed transient simulations with only two different driving GCMs selected from the group of models with better performance. We showed that the results from both downscaling experiments improved the 2 m air temperature over the sea during summer but not necessarily during winter. The latter finding was explained by the impact from the lateral boundary data. However, further downscaling experiments with other GCMs are necessary to illuminate the impact from various data sets. In addition, it is important to note that further model development to improve RCAO is necessary. We identified too low a wind speed over sea (although the higher resolution improved the situation) and too high an air temperature over ice covered areas, suggesting perhaps the shortcomings of incoming long-wave radiation during winter.

5% BSA/PBS for the detection of FkpA. Subsequently, primary antibodies were detected with goat anti-mouse IgG (H + L) conjugated with horseradish peroxidase (HRP) (Jackson Immunoresearch, PA) at a 1:2000 dilution. Color was developed NVP-LDE225 mouse with 1-Step TMB-Blotting substrate solution (Pierce, IL). The amount of functional Fab binding to target antigens was determined by ELISA. Ninety six-well high binding MaxiSorp® assay

plates (Nunc, NY) were coated with 1–3 μg/ml antigen diluted in phosphate buffer saline (PBS). EpCAM (bound by ING-1 Fab), IL1β (bound by XPA23 Fab) and Tie-1-Fc (bound by CF1 Fab) antigens were coated at 3 μg/ml. Kinase (bound by BM7-2 Fab) was coated at 2 μg/ml. Human insulin receptor (huINSR) (bound by 83-7 Fab) was coated at 1 μg/ml. Biotinylated gastrin (a 14-mer peptide recognized by the C10, D1, and E6 Fabs) was coated at 1 μg/ml in PBS on Reacti-Bind Streptavidin-coated 96-well plates (Thermo Scientific, MN). The coated plates were then incubated overnight at 4 °C and blocked with 5% non-fat dry milk (Nestlé, OH) in PBS buffer (no blocking was required for the streptavidin-coated plates). Plate washes were carried out in PBS

with 0.05% TWEEN®-20. Dilutions of Fabs, and primary Protease Inhibitor Library cell assay and secondary antibodies were performed in 5% non-fat dry milk in PBS. Fabs were allowed to bind to their blocked antigens for 1 h at room temperature. The presence of ING1, XPA23, CF1, BM7-2, C10, D1, and E6 Fabs was confirmed with goat-anti-human IgG [specific for F(ab′)2] (Jackson Immunoresearch) at 1:2000 dilution, followed by donkey anti-goat

IgG (H + L) conjugated with HRP (Santa Cruz Biotechnology, CA) at 1:10,000 dilution. The 83-7 Fab was detected using rabbit-anti-mouse IgG [specific for F(ab′)2] (Jackson Immunoresearch) antibodies at 1:2000 dilution, followed by goat anti-rabbit IgG (H + L) conjugated with horseradish peroxidase (Jackson Immunoresearch) at 1:10,000 dilution. The assay was developed with TMB soluble substrate (EMD Chemicals, CA). The reaction was quenched with 4.5 N H2SO4 and read at 450 nm using a SpectraMax® Plus microplate reader (Molecular Devices, CA). The amount of total Fab expressed in the Olopatadine periplasm was determined by ELISA. For the detection of ING1, XPA23, BM7-2 and CF1 human kappa Fabs, high binding MaxiSorp 96-well plates were coated with 3 μg/ml goat-anti-human kappa IgG (Invitrogen) diluted in PBS. Similarly, the murine kappa 83-7 Fab was detected with 3 μg/ml goat-anti-mouse kappa antibodies (Jackson Immunoresearch) and the human lambda C10, D1, and E6 Fabs with 3 μg/ml goat-anti-human lambda IgG (Pierce). Coated plates were incubated, blocked and washed, as previously described. Fabs were detected using rabbit anti-V5 (Sigma) primary antibody at 1:2000 dilution, followed by goat anti-rabbit IgG (Fc-specific) conjugated with HRP (Jackson Immunoresearch) at 1:10,000 dilution. The development of the assay was performed as previously described.

Furthermore, a very important factor for developing iron deficiency after blood donation is the frequency of donation. The

Council of Europe recommends PFT�� research buy no more than 4 whole blood donations in female and 6 donations in male donors per year [51]. Some European blood establishments have even lower total numbers of whole blood donations (e.g. in Switzerland 3 donations per year in female and 4 in male donors). With these intervals, the risk of depletion of iron stores should be acceptable in the vast majority of healthy volunteer donors. However, many blood donors still develop iron deficiency or even iron deficient anemia. Considering the shrinking of the donor pool that many blood donation facilities are going to face in the next years,

the interest on preventing significant iron deficiency and in particular iron deficiency anemia is increasing. Currently there are many groups investigating laboratory tests and/or prediction models to minimize donor deferral due to low hemoglobin, one of the main reasons leading to a loss of blood donors. At some blood donation centers, larger hematology analyzers and other lab tests such as ferritin or zinc protoporphyrin (ZPP) are available. However the added value of these additional tests to predict iron deficiency or low hemoglobin deferral CDK inhibitor review at the next intended donation is not yet established. Ferritin is used in some blood centers in order to prevent donors from developing iron deficiency without anemia or even overt iron deficient anemia. Ferritin is not a point of care analysis and is rather cost intensive. O’Meara et al. investigated buy Lenvatinib the value of routine ferritin testing and recommended an algorithm at the detection of anemia or iron deficiency without anemia. Donors were offered extending donation interval, change of diet or oral iron supplementation alone or in different combinations, according to donor’s

needs and wishes. Donors were referred to their GP when medical history was abnormal [3]. With this strategy, they could show that introduction of routine ferritin measurement was improving donor Hb and ferritin when following an algorithm for donor counseling based on Hb and ferritin, particularly in the group of women of childbearing age. Stern et al. investigated the value of ferritin, HB and red blood cell indices (MCV and MCHC) to predict low HB deferral at the next visit. This study found that hemoglobin was the best single marker for predicting low HB at the next visit. Ferritin levels were found to be of additional value in blood donors with Hb 5 μg/mL and less above Hb cutoff values [2]. However this finding has not yet been validated prospectively. In a recent study, Kiss et al. showed that red cell indices are of limited value for use as diagnostic tools in blood donors at risk for iron deficiency [52].

Presumably then, lower volume of the left PFC and integrity of the CC leads to impaired trans-callosal inhibition and additional recruitment of the right PFC found in functional MRI (fMRI) studies. We shall refer to this as the inhibitory hypothesis. However, another possible interpretation

is that of partial compensation ( Duverne et al., 2009 and Rossi et al., 2004), which suggests that whatever auxiliary processing is facilitated by the additional activation found in some older people is not sufficient to fully replicate a normally-functioning network, but would lead to much poorer performance if this alternative cognitive route were not available. We shall Antidiabetic Compound Library in vitro refer to this as the partial compensation hypothesis. Predictions from these two hypotheses can be formalised and usefully tested by examining the neurostructural correlates of verbal memory performance in older age. We address this question from the following viewpoint: Disruption

to one or more components of the large-scale brain network involved in memory may disrupt the state of normal parallel processing necessary to support unhindered performance (Bressler and Menon, 2010 and Mesulam, 1990). Accumulated brain insults over the life course may well be such a mechanism of disruption. For each component of the large-scale memory network, such insults can be broadly indexed by individual differences in diffusion and structural MRI measures (white matter tract integrity parameters

and regional brain volumes controlled for intracranial volume). We shall therefore use structural brain measures of an Afatinib a priori selection of memory network components (hippocampus, CC and lateral frontal lobe) to test competing accounts of frontal lobe involvement in verbal memory performance among Proteasome inhibitor a group of healthy older adults in their early 70s. We first aim to verify that left frontal lobe, hippocampus and CC constitute parts of a memory network and that each contributes unique variance to memory performance (Bressler and Menon, 2010 and Mesulam, 1990). The inhibitory hypothesis would predict positive associations between memory ability and indices of left lateral frontal lobe and anterior CC (genu; Buckner and Logan, 2002, Logan et al., 2002 and Persson et al., 2006; Sullivan & Pfefferbaum, 2007). Furthermore, a significant positive relationship between right frontal volume and memory ability would be incompatible with the inhibitory hypothesis, which suggests no benefit to verbal memory performance from a larger right frontal lobe. Conversely, the partial compensation hypothesis (Duverne et al., 2009 and Rossi et al., 2004) would assert that larger volume of the area providing auxiliary processing (in this case, the right frontal lobe) would positively associate with memory score, but only for poorer performers, who putatively rely on its compensatory function.
