“Summary of: Machado LAC et al (2010) The effectiveness of the McKenzie method in addition to first-line care for acute low back pain: a randomized controlled trial BMC Medicine 8: 10. [Prepared by Julia Hush, CAP Editor.] Question: Does the addition of McKenzie treatment to first-line care improve symptoms and function for patients with acute low back pain? Design: A randomised controlled trial with concealed allocation and blinded outcome assessment. Setting: 27 primary care medical practices in Sydney, Australia. Participants: Patients aged between 18 to see more 80 years seeking

medical care from a primary care physician for a new episode of acute non-specific low back pain. Nerve root compromise, serious spinal pathology, and recent spinal surgery were exclusion criteria. Randomisation of

148 participants allotted 73 to the McKenzie treatment and first-line care group, and 73 to a first-line care only group. Interventions: Both groups received the following recommended first-line care for acute low back pain: advice to remain active and avoid bed rest, reassurance of a favourable prognosis and instructions to take paracetamol. In addition, the intervention group received Icotinib purchase McKenzie therapy, commenced within 48 h of their physician consultation. Treatment was Libraries provided by 15 accredited McKenzie therapists. Treatment for most patients encouraged directions of movement and postures that centralised pain. Patients received up to 6 treatment sessions over 3 weeks. They were provided with the book Treat Your Own Back, prescribed home exercises, and most were prescribed

lumbar rolls. Outcome measures: Primary outcomes were pain and global perceived effect. Pain was measured during the first 7 days, and at Weeks 1 and 3, with the Numerical Rating Scale scored from 0 (no pain) to 10 (worst pain possible), with a between-group difference of 1 unit considered clinically important. Patient-rated global perceived effect was assessed at 3 weeks on a –5 to 5 scale, anchored heptaminol at ‘vastly worse’ and ‘completely recovered.’ Secondary outcome measures were disability, function, global perceived effect at 1 week, persistent low back pain at 3 months, and use of additional health care services. Results: 138 participants provided data at 3 months. At Week 1, pain was less in the McKenzie treatment group by 0.4 points (95% CI –0.1 to –0.8). At Week 3, pain was less in the McKenzie treatment group by 0.7 points (95% CI –1.2 to –0.1). The groups did not differ on other outcomes. However, patients receiving McKenzie treatment sought less additional health care than those receiving only firstline care (p = 0.002).

Cependant sa présence sur plus de quatre niveaux de coupe de la corona radiata jusqu’au pont, sa largeur (supérieure à 6 mm) et sa visualisation également sur les séquences

pondérées en densité de protons seraient plus spécifiques. Un hypersignal des cordons antérieurs this website de la moelle est également rapporté. Un hyposignal linéaire du cortex précentral est décrit avec une fréquence très variable. La signification de cette « ligne noire » visible sur les séquences pondérées en T2 reste discutée : elle pourrait correspondre à des dépôts ferriques témoignant de la dégénérescence neuronale ; des hyperintensités de la substance blanche sous-corticale localisées dans le gyrus précentral sont décrites sur les séquences flair, T2 et en densité de protons. Pour certains, leur spécificité serait de 94 % et donc supérieure à celle de l’hypersignal du faisceau pyramidal. Une atrophie corticale fronto-temporale, classique chez les patients atteints de démence fronto-temporale serait également souvent présente en l’absence d’atteinte des fonctions cognitives. Ces résultats doivent être confirmés par des études prospectives. Surtout, l’IRM

aide au diagnostic différentiel. L’IRM médullaire permet find more d’éliminer une myélopathie cervicale ou une ischémie médullaire, notamment dans les formes localisées aux membres supérieurs ; une syringomyélie ; une atteinte du cône terminal dans les formes localisées aux membres inférieurs. L’IRM cérébrale est indiquée dans les formes bulbaires

ou pseudo-bulbaires pures et permet d’éliminer une pathologie du tronc cérébral (tumeurs, lacune), de la base du crâne (infiltration). Les autres techniques d’imagerie (spectroscopie IRM, tenseur de diffusion, TEP et TEMP) sont en cours d’évaluation dans la SLA. not L’examen du LCS est normal dans la SLA : il n’y a ni réaction cellulaire, ni hyperprotéinorachie. La présence d’une anomalie est donc un élément d’orientation vers une autre affection : une hyperprotéinorachie évoque une compression médullaire, un syndrome paranéoplasique (association à un lymphome ou un cancer) ; une réaction cellulaire oriente vers un Modulators processus infectieux (maladie de Lyme, syphilis, VIH), un processus néoplasique ou lymphomateux (cellules anormales). Leur recherche est orientée par le contexte clinique [64]. Le diagnostic de neuropathie motrice pure (avec ou sans bloc de conduction) repose sur le déficit moteur prédominant aux membres supérieurs (diminution ou absence des ROT), l’ENMG et le dosage des anticorps (AC) anti-GM1. L’amyotrophie monomélique bénigne non évolutive est affection rare du sujet jeune se traduisant par une atteinte du motoneurone pure limitée à un membre. Elle se caractérise par une évolution lentement progressive suivie par une stabilisation après quelques années. Le syndrome post-poliomyélitique ne pose habituellement pas de problème diagnostique.

Standardized case information was abstracted from the hospital re

Standardized case information was abstracted from the hospital record. Sequelae were defined as complications attributable to IMD still present at discharge. The surveillance methodology has been detailed elsewhere [19] and [20]. Ethics approval was obtained at all participating hospitals. All IMPACT MenB cases with a viable isolate that occurred from 2006 to 2009 and were identified

as of August 2010 were included. NML determined serogroup, serotype, sub-serotype and PorA sequencing of case isolates. The clonal identity of isolates (defined by Multilocus Sequence Typing (MLST) [21]) and PorA variants were determined following the guidelines selleck included in the Neisseria pubMLST website [22].

The Libraries classification of fHbp followed the scheme available in the public fHbp database which divides peptide subvariants among three major variants, 1, 2 and 3 [22]. This peptide ID is similar to the Novartis classification, although in the Novartis classification it is preceded by the major variant number. NHBA and NadA classification followed Lucidarme et al. [23] and Bambini et al. [24]. HPA studied the levels of expression and cross-reactivity of NadA, fHbp, and NHBA in the MenB isolates using the MATS ELISA relative potency (RP) [15]. The MATS method established a minimum level of RP, named the positive bactericidal selleck compound threshold (PBT) that predicts whether a given MenB isolate would be susceptible to killing in the human serum bactericidal antibody assay by antibodies induced by 4CMenB. Strain coverage was defined as the proportion of strains with RP above the PBT for at least one vaccine antigen in the MATS ELISA or matched to the PorA subtype P1.4 [15]. Dichloromethane dehalogenase To account for inter-laboratory differences

in the MATS, the 95% confidence intervals (CI) for vaccine strain coverage were calculated according to an inter-laboratory standardization study [25]. Chi-square and Fisher’s exact tests were used to test for significant difference between groups. SAS version 9.3 (SAS Institute, Cary NC) was used for all analyses. A total of 157/200 (78.5%) MenB cases were tested. A viable isolate was not available for 2 cases and 41 cases were confirmed solely by PCR. No significant differences in PCR confirmation rates were found by age or center (data not shown). The most frequent ccs among the 68 different STs identified were cc41/44 (n = 51), cc269 (n = 51), cc35 (n = 11), cc32 (n = 8) and cc60 (n = 6) cc213 (n = 2). Of the remaining 28 isolates, 21 were unassigned and 7 were singularly occurring ccs. Although cc41/44 and cc269 occurred with the same frequency, 25 different sequence types (ST) were identified among isolates in cc41/44 and only three of these contained multiple isolates (ST-154 (n = 15) and ST-571 (n = 11) and ST-340 (n = 3). In contrast, only 9 STs were found in cc269 and 90.

Both assays are time intensive, highly variable, and limited in t

Both assays are time intensive, highly variable, and limited in throughput as they require expert visual analysis. Thus, a novel, quantitative cell-based in vitro measles infectivity assay ( Fig. 1) for quantifying the infectivity of MV in standard 96-well microtiter plates was developed. The fluorescence-based assay uses a recombinant Edmonston-derived laboratory-adapted MV expressing enhanced green fluorescent inhibitors protein (MVeGFP) [27] and is quantitated using automated image analysis. The assay has a wide dynamic range (≥2.0 orders of magnitude), low variability (Relative Standard Deviations, RSDs ≤30%, as measured through the

thousands of control formulations across the screening campaign), and short duration (<4 days). Two additional measures not typically used during measles infection GSK1120212 were implemented to optimize this assay for the HT screening process. First, fusion

inhibitory protein (FIP) was used to prevent cell-to-cell spread and therefore secondary infections, and thereby increase the dynamic range of the assay. In a typical MV infection, neighboring cells fuse to form multinucleated syncytia, which markedly vary in size, shape, brightness and sharpness. Physical overlaps between syncytia create an upper limit on dynamic range, and their non-uniform appearance makes accurate BKM120 quantification challenging, especially when using automated image analysis. FIP prevents syncytia formation through an unknown molecular mechanism [30]. When FIP is added shortly after the initial infection, fluorescent infectious centers remain discrete, single objects of uniform size and shape (Fig. 1a), each representing a single cell infected by MVeGFP. Second, crotamiton the relatively low titer of MV in typical cell culture (∼106 plaque-forming units) plus the additional reduction of virus concentration as a result of its dilution into formulation places limits on the upper bound of detection. In order to address these challenges, we introduced a “spinoculation” step. Centrifugation of inoculated cell monolayers at low speed has been shown to enhance the detection of viable virus (e.g. for HIV [31]),

presumably by bringing infectious particles into close contact with the cells, thereby facilitating infection. Addition of FIP to the viral inoculum prior to centrifugation completely eliminated infection, suggesting that the molecular mechanism of viral entry is not affected (results not shown). Spinoculation, however, causes an apparent increase in viral titer of approximately 0.5 log10 increasing the upper end of the range (Fig. 1b). This apparent increase in titer reduces consumption of virus during HT screening and allows for greater dilution of virus stock into formulation. FIP and spinoculation increase the dynamic range of the assay approximately 2.5-fold from 1.8 logs (∼5 to ∼300 object counts, data not shown) to ∼2.

the IV bevacizumab group and at week 48 (−0.29 ± 0.04 logMAR: ∼3 ETDRS lines) in the IV ranibizumab group. There was a significantly greater mean improvement in BCVA in the IV ranibizumab group compared with the IV bevacizumab group at weeks 8 (P = .0318) and 32 (P = .0415), with a trend towards significance at weeks 28, 36, and 40 (P < .10) ( Table 2, and Figure 1, Top). With respect to the proportion of eyes losing or gaining ≥10 or ≥15 ETDRS letters, no significant difference between IV bevacizumab and IV ranibizumab groups was observed (P > .05). In the IV bevacizumab group, the proportion of eyes losing ≥10 ETDRS letters was 6% at week 16 and from weeks 28-40, and 3% at weeks 12, 20, and 24. The proportion of eyes in the IV bevacizumab group that lost ≥15 letters was 3% at weeks 32 and 36. In the IV ranibizumab group, a loss of ≥10 ETDRS letters was not observed at any follow-up visit. A gain

of ≥10 ETDRS letters was observed in 45% and 44% of eyes in the IV bevacizumab and IV ranibizumab groups, respectively, at week 16, and in 61% and 68% in the 2 groups, respectively, at week 48. A gain of ≥15 letters was observed in 15% and 16% of eyes in the IV bevacizumab Epacadostat order and IV ranibizumab groups, respectively, at week 16, and in 39% and 48% in the 2 groups, respectively, at week 48 (Figure 1, Bottom). At baseline, mean ± SE central subfield thickness was 451 ± 22 μm and 421 ± 23 μm at baseline in the IV bevacizumab and IV ranibizumab groups, Modulators respectively (P = .4062) ( Figure 2, Top). Intragroup significant reduction in central subfield thickness too compared with baseline was observed at all study follow-up visits (P < .05). Maximum mean central subfield thickness reduction occurred at week 44 (−136 ± 23 μm) in the IV ranibizumab group and at week 48 (−126 ± 25 μm) in the IV bevacizumab group ( Table 2, and Figure 2, Bottom). There was no difference in mean central subfield thickness reduction between

the IV bevacizumab and IV ranibizumab groups at any of the study follow-up visits. However, there was a significantly higher proportion of eyes with a central subfield thickness ≤275 μm in the IV ranibizumab group compared with the IV bevacizumab group at weeks 4 (P = .0029; likelihood ratio), 28 (P = .0077), 36 (P = .0028), and 44 (P = .0292) ( Figure 3). The mean (± standard error of the mean; SEM) number of injections in the IV bevacizumab group was 9.84 ± 0.55, which was significantly (P = .005; Wilcoxon) higher than the mean (± SEM) number of injections in the IV ranibizumab group (7.67 ± 0.60 injections). In the IV bevacizumab group, 16 eyes received 12 injections, while only 4 eyes from the IV ranibizumab group were treated with 12 injections ( Figure 4). Two eyes from 2 different patients received rescue laser therapy: 1 from the IV ranibizumab group at week 32 and the other from the IV bevacizumab group at week 36.

Each petri dish was placed with one worms and observed for paralysis or death. Mean time for paralysis was noted when no movement of any sort could be observed, except when the worm was shaken vigorously; the time death of worm (min) was recorded after ascertaining that worms neither moved when shaken nor when given external stimuli. The test results ( Table 7) were compared with Reference compound Metronidazole (10 mg/ml) treated samples. The B. diffusa Fig. 1 leaves-opposite in unequal pairs, larger ones 25–37 mm long and smaller ones 12–18 mm long ovate-oblong or suborbicular, apex rounded or slightly pointed, base subcordate or rounded, green and glabrous ABT-199 research buy above, whitish

The Transverse section of Leaf shows anomocytic stomata on both sides, numerous, a few short hairs, 3–4 celled, present on the margin and on veins, palisade one layered, spongy parenchyma 2–4 layered with small air spaces, idioblasts containing raphides, occasionally cluster crystal of calcium oxalate and orange-red resinous matter present in mesophyll. The plant B. diffusa (Nyctaginaceae) was screened for its macroscopical, microscopical, Physiochemical parameters, and florescence analysis

(day light, long UV), showed that they all within limit. Made the ethanolic extracts of the plant leaves by continuous hot extraction by Soxhlet apparatus, the percentage value of the extracts was 9.35%w/w. Preliminary phytochemical check analysis of ethanolic extracts showed the presence of alkaloids, Amino acids, Carbohydrates, Saponins, Tannins, and Triterpenes active phytoconstituents.  Fig. 8 data revealed that the ethanol extract showed anthelmintic activity at a concentration of 100 mg/ml, paralysis and death at similar concentrations. The other test concentrations of the extracts showed marked degree of anthelmintic activity. The anthelmintic 5 effect of extracts Fig. 10, Fig. 11, Fig. 12 and Fig. 13 is comparable with that of the effect produced by the standard drug Metronidazole Fig. 9. Parasitic helminths affect animals and man, causing considerable hardship and stunted growth. Hundreds of millions if not billions of human infections by helminthes exist worldwide and increased world travel and immigration from the developing countries. However tremendous advances have been made during the previous decade and a substantial number of synthetic precursors have been derived to cope up the damage caused by parasite, but unfortunately no effective medicine has been developed so far.

The electropherograms obtained were analyzed using the sequencing

The electropherograms obtained were analyzed using the sequencing analysis software (Sequence Navigator, version 1.01, Applied Biosystems). The nt and deduced aa sequences were compared with sequences available in the NCBI (National Center for Biotechnology Information) GenBank database using the BLAST (Basic Local Alignment Search Tool) program. Phylogenetic and molecular KPT-330 supplier evolutionary analyses were conducted using MEGA version 4.0 [36]. Dendrograms constructed were confirmed by two different methods,

neighbor joining and maximum parsimony. The data were analyzed using Epi Info 2002 and Stata 10.0. Chi square and Mann Whitney U tests were performed to determine the significance of differences observed between groups. Partial nucleotide HIF-1 pathway sequences of VP1, VP2, VP3, VP4, VP6, VP7, NSP1, NSP2, NSP3, NSP4 and NSP5 of the G10P[15] strains were submitted to the GenBank database and their accession numbers are HQ660637, HQ660638, HQ660639, FJ798615, FJ798616, FJ798617, HQ660640, HQ660641, HQ660642, FJ798618, HQ660643 respectively. The median (interquartile range [IQR]) age of the 394 children enrolled in the study was 10 (7) months, with >90% of children less than 2 years of age. The median Vesikari score of diarrheal severity was 11.0 and the children required

admission for a mean duration of 2.8 days. Of 394 children screened, we found that 158 children were infected with rotavirus (40%). The common G types identified in order of frequency were G1 (47/158, 29.7%), G2 (43/158, 27.2%), G9 (22/158, 13.9%), G10 (2/158, 1.2%), G12 (1/158, 0.6%) and mixed infections (27/158, 17.8%). The common P types were P[4] accounting for 57/158 (36%) samples, P[8] 57/158 (36%), P[11] 3/158 (1.8%) and P[6] 2/158 (1.2%). Mixed infections with varied P types were seen in 5 (3.2%). G typing alone was possible in 23 samples Terminal deoxynucleotidyl transferase (14.4%), only P typing in 5 samples (3.6%) and 11 samples were completely untypeable (6.9%). The common G:P inhibitors combinations seen

in children were, G2P[4] in 39/158 (24.6%) samples, G1P[8] in 29/158 (18.3%) samples, G9P[8] in 21/158 (13.2%) samples, G1P[4] in 4/158 (2.5%) samples and G10P[11] in 1/158 sample (0.6%) (Fig. 1a). We collected total of 627 samples from animals with diarrhea, including 589 cows (25 were calves), 2 buffaloes, 11 bullocks and 25 goats (11 were kids). The mean duration of diarrhea was 4.5 days for adult animals, 4 days for calves and 3 days for goat kids. Out of 627 animals we found 35 (1 bullock, 2 goats, 32 cows) infected with rotavirus (5.5%). The common G types identified in order of frequency were G6 (17/35, 48.5%), G2 (10/35, 28%), G10 (4/35, 11%), G8 (2/35, 5.7%) and mixed infections (2/35, 5.7%).

2 and Fig. 3). Terminal testing

revealed significant differences between Trametinib chemical structure the relative ACSA and relative MV of the ADM and ABH muscles of the two study groups (Fig. 2 and Fig. 3). With 12 weeks of standard shod running, the control group significantly increased only MV of the FDB (p = 0.03, Table 4, Fig. 4). Following the same 12-week period, the experimental group having transitioned to minimal shod running increased not only MV of the FDB (p = 0.03, Table 4, Fig. 5) but also MV and ACSA of the ADM (p = 0.009 and p = 0.007, respectively, Table 4, Fig. 5). Neither group significantly increased MV or ACSA of the ABH muscle. Prior to treatment, conformation of the longitudinal

arch did not differ between the randomly assigned groups (Table 5). The AHIss index of mean arch height in single limb support was equivalent at 0.36 in the two groups. Similarly, group comparison of the mean RAD, our measure of stiffness, showed no initial difference between the control and experimental groups (p = 0.33, d = 0.33). Neither group experienced a significant change in AHIss over the 12-week study period (Table 5). Similarly, post-treatment test of RAD showed no significant change in arch stiffness within either group (p = 0.21, d = 0.37). However, we identified an outlier among experimental runners at 3.5 SD from the group mean. An ad hoc test after outlier deletion yielded a significant effect of time by group (p = 0.04). LGK-974 mouse A follow-up paired t test of experimental runners showed significant change in post-treatment RAD (p = 0.013) suggesting a stiffening of the arch with minimally shod running ( Table 5). The results

of this 12-week longitudinal study suggest that endurance running in minimal support footwear stimulates Linifanib (ABT-869) changes in arch function and the intrinsic foot muscles of runners who previously used conventional running shoes. The experimental runners who transitioned from conventional running shoes to minimal footwear experienced multiple changes in their landing kinematics, foot musculature and arch conformation as hypothesized. No such changes were observed in the control group with the exception of an increase in flexor digitorum brevis volume. Volume appears to be a more sensitive and robust measure than CSA as the majority of significant findings were in the volume of the muscles over time. Although foot strength was not directly measured, the results of this prospective experimental study suggest that runners who transition to minimal footwear can develop a significant increase in foot strength. At the start of the study, 85% of our subjects were RFS, a proportion well within the range of previous reports3, 4 and 21 and one that suggests an RFS is typical of conventional shod running at endurance speeds.

05) Figure 5D shows the average deflection (n = 11,330 deflectio

05). Figure 5D shows the average deflection (n = 11,330 deflections, 28 electrodes from five sessions) and the power spectrum of the LFP trace over 400 ms windows centered on each deflection (100 ms before to 300 ms after the initial sharp voltage change). It revealed a large peak at alpha frequencies (12.2 Hz) and, indeed, the power spectra of the LFPs during strong deflection episodes showed a marked increase in alpha oscillations (∼12 Hz) (see Figure S4 for an example). We compared LFP oscillatory power on correct trials during baseline blocks with the postinjection blocks separately

for sessions or recording sites with and without deflections. In baseline blocks, there was a prominent alpha/beta band (10–30 Hz) during the fixation, delay, and saccade execution epochs (Figures 6A and 6B). During postinjection blocks after injection selleck chemicals llc of SCH23390 (n = 163 electrodes), but not saline (n = 84 electrodes), there was an increase in the power of oscillations

below 30 Hz compared to baseline blocks. The deflections have an alpha component (see above) so, naturally, sites with deflections (n = 95) showed an increase in alpha band (10–14 Hz) after SCH23390 and also in beta band (14–30 Hz) for novel and familiar associations over baseline blocks (Figures 6A and 6B, Wilcoxon test, p < 0.05, shaded areas; Figure 6C, last 20 trials/block). SAR405838 Importantly, this increase in low-frequency power in the LFPs was still observed in sites without deflections (n = 68, Figure 6B), indicating that the SCH23390-induced increase in low-frequency oscillations was not due to the deflections alone. This increase was more pronounced for novel than familiar associations in MTMR9 sites without deflections (Figures 6B and 6C; Wilcoxon test, p < 0.05). The increase in alpha/beta oscillations was also observed in sessions without deflections on any recording site (Figure S5)

and was greater at sites where blockade of D1Rs impaired learning compared to areas where learning was intact (Figure S5). Our findings indicate that dopamine D1 receptors in the monkey lateral PFC are likely to be involved in learning new cue-response associations but less involved in performance of familiar associations. After the injection of a D1R antagonist, especially in the ventrolateral PFC, monkeys learned new cue-response associations much more slowly, whereas performance of highly familiar associations was intact. Two not mutually exclusive possibilities may account for this dissociation: (1) familiar associations are not dependent on prefrontal D1Rs, and (2) they are dependent on another brain area, such as the striatum, where they could be encoded as habits (Graybiel, 2008).

A possible mechanism that may explain the reduction of APOE mRNA

A possible mechanism that may explain the reduction of APOE mRNA is related to the inhibitory effect of statins on the synthesis of oxysterols, which are LXR ligands Autophagy inhibitor and would lead to a decreased expression of LXR target genes. LXR regulates APOE expression in macrophages and adipocytes though direct interaction with two duplicated enhancer elements placed downstream of the gene

and responsive to LXRs [12]. Besides the up regulation of gene expression, it was demonstrated that LXR activation by incubating with a LXR agonist increases apoE secretion in HepG2 cells [33]. In our sample, although no reduction of LXRA expression by atorvastatin was detected, positive correlation between APOE and LXRA expression was observed before and after treatments. However, we only measured mRNA levels of LXRA and the transcriptional activity of LXRα by interacting with the APOE promoter was not evaluated. Additionally, APOE mRNA reduction by atorvastatin was APOE genotype dependant in our sample that could give some additional explanation of influence of genotypes on variation in response to statins. However further studies using a larger sample size and if possible more adequate cellular models are necessary. HT effects on APOE expression have been investigated

mainly in brain tissues where HT seems to confer neuronal protection and regeneration [34]. Estradiol treatment in cultured neurons causes a rapid (4 h) elevation of apoE [35]. Additionally, when ovariectomized mice were continuously treated with CT99021 estradiol [36], APOE up-regulation at acute treatment (five days) was observed in brain tissues, but this effect was lacked with longer estradiol exposure (14–49 days). On the other hand, estradiol administration increased

hepatic apoE levels in mice without affecting APOE mRNA [37]. No differences on PBMC APOE mRNA were detected after HT treatment in next our study, however according with above mentioned early findings long term treatment and posttranscriptional regulation could explain this fact. Moreover, an additional limitation of our work is the measurement of mRNA levels but not apoE protein, which would have enable us to elucidate posttranscriptional regulation of APOE in postmenopausal women. APOE mRNA expression in PBMC was down-regulated by atorvastatin in a process probably mediated by LXRα though reduction of oxysterols and this was influenced by APOE genotypes, nevertheless HT and HT associated to atorvastatin did not influence APOE expression.
