HSP90 (0.03 μg/mL, Cell Signaling Technology), and HSP105/110 (2 μ/ml, Novus). To normalize for protein loading, transfer, and detection, the blots were also immunostained with antibodies against the translation initiation factor Inhibitors,research,lifescience,medical eIF4E (0.3 μg/mL, Cell Signaling Technology) or α-tubulin (0.47 μg/mL, Sigma). Images were acquired with a Biospectrum imaging system (UVP, Upland, CA) equipped with a refrigerated Chemi 410 CCD camera and the VisionWorks LS software (UVP). Digital images were quantified using Scion Image for Windows beta 4.0.2 (SCION Corp., Frederick, MD). Gel lanes were selected and the signals transformed into peaks. The area under each peak (gray value) was transformed into an optical density (OD) value using the function: OD = Inhibitors,research,lifescience,medical Log10 (255/[255

− gray value]). The OD values of the protein of interest were normalized Inhibitors,research,lifescience,medical to the eIF4E or α-tubulin internal standard to compensate for variations in protein loading and transfer. Analysis of colocalization of HSF1 and the nuclear stain DAPI To investigate the possible translocation of HSF1 to the nucleus, astrocytes were immunostained with rabbit anti-HSF1 antibody and the cell nucleus was stained with DAPI. Confocal images were acquired, with care taken to avoid pixel saturation to prevent false colocalization. Gray scale 8-bit calibrated images (0.8–1 μm optical sections) were evaluated for colocalization of HSF1 and DAPI signals by a global statistic approach that performs intensity correlation coefficient–based Inhibitors,research,lifescience,medical Inhibitors,research,lifescience,medical analyses. We use the algorithm JACoP (Bolte and Cordelieres 2006) that calculates the Pearson’s coefficient of pixel intensity in both channels represented in

a scatter plot. The slope of the linear regression provides the rate of association of the signals ranging from 1 (total overlapping) to −1 (complete exclusion). Constitutively transcriptionally active Hsf1 construct We made use of a constitutively transcriptionally active form of HSF1 (Hsf1-act, BH-S) to determine whether the genes identified in the gene array are dependent on the activation of HSF1 for their expression. Hsf1-act has a long deletion of amino acids Oxygenase 203–315 in the regulatory domain of HSF1 (Zuo et al. 1995). The construct was generated by Dr. Richard Voellmy (University of Miami) and cloned into the pcDNA3.1+ vector (Invitrogen). Transfections were performed with 1.5 μg of DNA, 3 μL of lipofectamine LTX (Invitrogen), and 1.7 μL of Plus reagent (Invitrogen), and NU7441 ic50 sister cultures were transfected with an empty pcDNA3.1+ vector as a control. Cells were used 24–48 h after transfection.

Three cortico-striatopallido-thalamo-corti cal (CSPTC) pathways may be relevant to depression.76,77 Damage of the orbitofrontal circuit may lead to disinhibition, irritability, and diminished sensitivity to social cues.76 Damage of the anterior cingulate may result in apathy

and reduced initiative.76 Damage of the dorsolateral circuit may result in difficulties in set shifting, learning, and word list generation.76 These behavioral abnormalities resemble in part the depressive syndrome. Treatment response in vascular depression Several studies suggest that vascular depression may have a poor outcome. Late-onset Inhibitors,research,lifescience,medical depression, an entity that often occurs in the context of vascular disease, is a rather chronic disorder.78 In elderly dépressives, leukoencephalopathy

was found to be associated with low quantitative electroencephalogram (qEEG) coherence79,80; low qEEG coherence predicted failure to recover, residual depressive symptomatology, increased mortality, and disability.79,80 Inhibitors,research,lifescience,medical We studied the relationship of clinical, neuropsychological, and electrophysiological measures Inhibitors,research,lifescience,medical of prefrontal dysfunction with treatment response in elderly patients with major depression.81 Abnormal initiation/perseveration scores of the Dementia Rating Scale, psychomotor retardation, and long P300 latency of the auditory evoked potential predicted 58% of the variance in change of depression scores from baseline to 6 weeks. Depressed patients who remained symptomatic had more abnormal Inhibitors,research,lifescience,medical initiation/perseveration scores and longer P300 latency compared with depressed patients who achieved remission and control subjects. There were no differences between the last two groups. These findings suggest that prefrontal dysfunction is associated with poor or delayed antidepressant response in depressed elderly patients. Although not very specific, abnormal initiation/perseveration

Inhibitors,research,lifescience,medical scores, psychomotor retardation, and long P300 latency are thought to reflect striatofrontal impairment, an abnormality often caused by vascular disease.82 oxyclozanide We are currently Enzalutamide cell line conducting a study of average evoked responses following the Stroop response inhibition test. The Stroop requires integrity of the anterior cingulate and thus is more specific to frontal dysfunction than our earlier tests. Preliminary findings suggest that, compared with controls, depressed elderly patients overrecruit prefrontal neurons during the response inhibition task (Figure 3). Further research will examine whether this abnormality is associated with poor réponse to antidepressants. Figure 3. Increased frontal activation in a 73-year-old patient with major depression (top) compared with a 70-year-old psychiatrically normal subject (bottom).

Repeated pain/stress exposure in very preterm infants takes place at a time of rapid brain development and programming of the hypothalamic-pituitary-adrenal (HPA) axis. Synaptic connections are being formed, activity-dependent selective cell death (apoptosis) shapes the developing brain, and integrated cortical networks Inhibitors,research,lifescience,medical are becoming established.13 These processes are affected by “developmentally unexpected” stimulation.1 Moreover, electrophysiological evidence suggests that acute pain induces diffuse brain activation across

multiple regions in preterm neonates,14 thus these neurologically immature infants are the most susceptible to long-term effects of pain. NEONATAL PAIN AND THE PRETERM DEVELOPING BRAIN In the late second and third trimesters of fetal life, the period when the very preterm neonate born at 24–32 weeks’ gestation is in the NICU, the developing brain undergoes major changes in cytoarchitecture and development of Inhibitors,research,lifescience,medical functional networks.

During this lengthy period of hospitalization of neonates born extremely preterm (≤28 weeks’ gestation) brain development includes establishment and differentiation of subplate neurons, alignment, orientation and layering of cortical Inhibitors,research,lifescience,medical neurons, elaboration of dendrites and axons, formation of synapses, selective pruning of neuronal processes and synapses, and proliferation and differentiation of glial cells.15 Using advanced magnetic resonance imaging (MRI) it is well-established that structural and functional differences in brain development are evident Inhibitors,research,lifescience,medical in preterm infants early in life, extending to adulthood.15–18

The etiology of neurodevelopmental problems in preterm infants who escape major brain Inhibitors,research,lifescience,medical injury is linked to disturbances in the expected organizational events in brain development.19 Furthermore there is “selective vulnerability” of specific cell populations, particularly the pre-oligodendrocytes and the transient subplate neurons.20 Early lineage oligodendroglia are vulnerable Sclareol to insults that do not affect mature myelin-forming oligodendrocytes. These selective cell vulnerabilities in the preterm brain are reflected in white matter injury and have been linked to hypotension, infections, and selleck products inflammation.20,21 Multifocal white matter injury is the characteristic brain injury pattern in premature neonates, identified on MRI in about one-third of preterm neonates, and associated with motor and cognitive problems.21 White matter injury is followed by diffusely abnormal microstructural and metabolic brain maturation as preterm newborns develop from early in life to term-equivalent age. Abnormalities in brain maturation persist through childhood and adolescence and are associated with adverse neurodevelopmental outcomes.

It is also common to treat all patients with placebo during the run-in. The case against using placebo during the run-in has been argued strongly by Senn.14,15 He points out that this stratagem involves the treating physician deceiving the patient, whereas in more conventional uses of placebo both are in the same state of ignorance. As far as the subsequent comparison of randomized treatment arms is concerned, it would be just as acceptable to have a runin without treatment: it does no harm to the main objective of the study. The onus to prove their case lies squarely on those who believe that placebo treatment

Inhibitors,research,lifescience,medical is necessary during a run-in. Losses of patients from clinical trials The incidence of dropout from clinical trials in schizophrenia is high. This is one of the factors that make these trials particularly difficult to interpret because the biases introduced by dropouts

are difficult to assess. All possible steps should be taken to minimize the number of dropouts and to shed light on the potential bias Inhibitors,research,lifescience,medical they induce. The reasons for dropout should be carefully SNS-032 ic50 documented. After stopping their trial medication, dropouts should Inhibitors,research,lifescience,medical still be followed up as fully as possible as planned in the protocol. Key measurements should also be made at the time of stopping treatment. The primary analysis of a placebo-controlled comparison should include all randomized patients

Inhibitors,research,lifescience,medical regardless of dropout. A “per protocol” analysis should support the primary analysis. There should be a full exploration of the sensitivity of the main results of the trial to the influence of the dropouts, taking into account the reasons for dropout, and the corresponding potential biases that they might, cause. Short-term trials The efficacy of a neuroleptic agent can generally be established in a short-term trial lasting about 6 weeks, studying acute exacerbations of the disease. A dose-ranging study might, Inhibitors,research,lifescience,medical include three or more doses, placebo (ethically justified, as described earlier), and a standard PDK4 treatment arm, making five treatment arms in all, to establish the optimal dose and the lower end of the dose range. A phase 3 confirmatory study would use the dosing regimen intended for licensing and would also ideally include placebo and active control. Long-term studies The difficulties inherent in schizophrenia trials make it imperative that licensing decisions are made on the basis of controlled trial data. It is not sufficient to monitor a group of patients exposed to long-term therapy and record their progress. The data from such a study would probably be supportive, especially for safety purposes, but would not establish a regulatory claim. The duration of controlled data adequate to establish use as maintenance therapy is of the order of 1 year.

In most affected communities, the condition is often accepted as normal since to them, all growing children pass blood in their urine and “grow out of it”. Mass treatment of school children has been a regular exercise often undertaken by stake holders to decrease the disease burden and reduce transmission in selected communities. Urinary schistosomiasis can have devastating impact on the urinary tract which is often unacknowledged and unevaluated. Such omission

AZD6244 price could have implication for progressive renal damage which, if not detected and treated, could lead to end stage renal failure and death. We present five (5) cases of urinary schistosomiasis with severe obstructive uropathy seen at the paediatric nephrology/urology units of Komfo Anokye Teaching Hospital, Ghana. All five cases had some degree

of anaemia and hypertension. Two of the five cases presented with end stage renal failure and died subsequently whilst two underwent successful surgery. One made a spontaneous recovery from the urinary obstruction though still has significant renal impairment. This potential devastating effect of urinary schistosomiasis on the kidneys calls for thorough evaluation and assessment of each confirmed case to include blood pressure measurement, full blood count, and ultrasonography of the urinary system. Mass screening programmes should be combined with portable ultrasonography of the kidneys, ureters and bladder.

Nephrostomy Introduction Urinary schistosomiasis is a common parasitic disease Gefitinib order affecting hundreds of millions of people in Histone demethylase many countries in the tropics.1–3 It is caused by the blood fluke Schistosoma haematobium. The disease is prevalent in areas where there are large water bodies for irrigation and particularly where dams have been constructed.1,4 In Ghana, the disease is endemic and widely distributed in many areas around the major rivers.5,6 Prevalence rate of 12.4% has been reported in some endemic regions in Ghana.6 Because of the lifestyle and behaviour of children in swimming in large water bodies, they are the most at risk of the disease.2,7 The disease manifests principally as passage of haematuria, overt (terminal or total) or covert. In endemic regions, there is a high prevalence of haematuria among school age children to the extent that children who do not pass blood in their urine may be regarded as “abnormal” by their peers.2 The infection is confirmed by the identification of the ova (with a lateral spine) on urine microscopy. The widespread endemicity of this disease and its familiarity in such regions of the world often tend to downplay the devastating impact that this disease can cause. Quite often, individual clinical cases are only treated with praziquantel (the drug of choice) without recourse to further evaluation and investigations.

2010], included changes in MADRS total and individual symptom scores and CGI-C scores. Safety and tolerability were assessed by recording the occurrence of treatment-emergent adverse events (TEAEs) at each visit. Data analysis All patients treated with at least one dose of study drug were eligible for efficacy and tolerability analyses (intent-to-treat). Time to remission was determined using the Kaplan–Meier method. Comparison Inhibitors,research,lifescience,medical of time to remission between RLAI and quetiapine was performed using the log-rank test with alpha of 5%. A hazard ratio (HR) was calculated to estimate the difference in remission risk between RLAI and

quetiapine. Demographics, disease characteristics, and adverse events (AEs) were assessed

using descriptive analyses. Within-group differences for ordinal/continuous data were assessed using the Wilcoxon two-sample test. Nominal data were tested using the Fisher exact test. Inhibitors,research,lifescience,medical All statistical tests were interpreted at the 5% significance level (two-tailed). Results The results of the designed prespecified analysis of the ConstaTRE trial after the last enrolled patient completed 1 year of treatment led to the recommendation by independent experts to terminate the trial early due to achieving the predetermined difference in efficacy. Inhibitors,research,lifescience,medical Patients ConstaTRE included an evaluable sample of 666 patients (329 RLAI and 337 quetiapine). Baseline demographics have been previously described and were similar between treatment groups [Gaebel et al. 2010]. Most patients were male (58.0%), Caucasian (97.6%), and diagnosed with schizophrenia (82.3%), with a median time since diagnosis of 7 years

Inhibitors,research,lifescience,medical (range 0–66 years). Among the 666 evaluable patients, 2-year treatment was completed by 45.9% of patients randomized to treatment with RLAI (n = 151) and 35.6%of patients randomized to quetiapine (n = 120). The between-group difference in treatment completion was significant (p = 0.0074). Mean mode ± SD drug doses were 33.6 ± 10.1 mg RLAI every 2 weeks and quetiapine 413.4 ± Inhibitors,research,lifescience,medical 159.2 mg daily. Remission Efficacy data were buy LY2157299 available for 327 patients treated with RLAI and 326 treated with quetiapine. PANSS remission severity criteria were met Thymidine kinase at baseline by 113 patients treated with RLAI (34.6%) and 112 with quetiapine (34.4%). Full remission (including both severity and duration criteria) was more likely to occur at some point during the study in patients treated with RLAI(n = 167, 51.1%) than quetiapine (n = 128, 39.3%; p = 0.003). The percentage of patients in full remission at each assessment, starting at 6 months, is shown in Figure 1. Among those patients achieving full remission, remission was maintained until the end of the trial in 144 patients treated with RLAI (86.2%) and 102 treated with quetiapine (79.7%). This numerical difference was not significant.

MCUG showed severe narrowing of the distal half of the posterior urethra with attendant dilatation of the proximal prostatic urethra. No vesicoureteric reflux was observed. IVU showed bilateral hydroureteronephrosis with moderate bladder filling implying distal ureteral involvement. The urinary tract infection (UTI), hypertension and schistosomiasis were appropriately treated with antibiotics, amlodipine and praziquantel respectively. Patient was also given Iron for 3 months. Bilateral nephrostomy tubes were insertion and urethral catheter passed. He subsequently underwent surgery for bilateral ureteric re-implantation. Intra-operative check details findings

showed bilaterally thickened distal ureters with stenosis and a thickened urinary

bladder. Follow up urine culture was sterile and BP was controlled. Repeat USS showed moderate dilatation of right renal pelvis and calyces and no evidence of dilated renal calyces or pelvis on the left. Patient is doing well and is on long term follow up. He has indwelling urethral catheter in place and has been scheduled for urethrocystoscopy to fully evaluate the lower urinary tract and to rule out missed posterior urethral valve. Case 4 Eleven-year-old I.T. was referred from a district hospital with provisional diagnosis of chronic renal failure. Patient hails from Suhum, a community endemic for schistosomiasis. His presenting complaints learn more included bodily swelling, cough, and chest pain of a week’s duration and terminal haematuria for a year. Essential findings on physical examination were generalised oedema, pallor, dyspnoea, respiratory rate of 36/min and bilateral basal crepitations. The pulse rate was 112/min, BP 140/100mmHg (both systolic & diastolic > 99th centile for age & sex), heart sounds S1S2 were present and normal, there was no murmur. There was non-tender hepatomegaly of 3cm. The bladder was not palpable. Bedside urine dipstick showed protein 3+ and blood 4+. Laboratory test results were as follows: Hb 8g/dl, MCV 75 fl., WBC 6.5× 109/l Platelet count of 220 × 109/l; Urine microscopy showed pus cells > 20/HPF, RBCs > 100/HPF, granular cast 2+; S. haematobium ova ++; urine culture was negative;

blood urea 37mmol/l , creatinine 786µmol/l, Na+ 121 Levetiracetam mmol/l, K+ 5.7 mmol/l, Ca2+ 1.8 mmol/l, Mg2+ 0.9mmol/l, PO4- – 1.4mmol/l , albumin 32g/l, total protein 70g/l and cholesterol 5.7mmol/l. CXR showed cardiomegaly with pulmonary oedema and USS showed severe bladder wall thickening with right hydroureteronephrosis. Left kidney was shrunken with increased echogenicity and loss of corticomedullary differentiation Diagnoses of congestive cardiac failure 2° hypertension, and chronic renal failure 2° obstructive uropathy from chronic urinary schistosomiasis were made. Heart failure was appropriately treated with high dose frusemide, and hypertension treated with amlodipine. Urethral catheter was passed. Urine output over 24 hours into admission was 0.48mls/kg/hr.

The endosomes thus formed are eventually converted into the lysosomes and ultimately result in the drug release [102]. Liu et al. developed SWCNT conjugated with paclitaxel (PTX) and reported the nonreceptor mediated endocytosis selleck kinase inhibitor mechanism for the cellular uptake in murine 4T1 breast carcinoma cells [110]. Islam et al. investigated the cellular uptake of pluronic copolymer-stabilized, purified ~145nm long single walled carbon nanotubes (SWCNTs) through a series of complementary cellular, cell-mimetic, and in vitro model membrane experiments. The Raman intensity distribution, obtained from the G-band (1590cm−1), shows SWCNT concentration Inhibitors,research,lifescience,medical localized to the midplane of a fixed, hematoxylin-labelled

cell. SWCNTs were preferentially Inhibitors,research,lifescience,medical located within cells versus the extracellular regions, and most SWCNTs were localized in the perinuclear region. SWCNTs localized within fluorescently labelled endosomes and confocal Raman spectroscopy showed a dramatic reduction in SWCNT uptake into the hematoxylin-labeled HeLa cell at 4°C compared with 37°C, after being incubated for 2 days. These data suggested energy-dependent

endocytosis. Inhibitors,research,lifescience,medical To confirm this, a direct measurement to check the endocytosis was conducted in which endocytosis in HeLa cells was visualized using a Green Fluorescent Protein, GFP-tagged RhoB-GTPase, which labels endosomes in mammalian cells. On confocal imaging it was confirmed that the internalization of SWCNTs was occurring through the endocyte formation as there was a slight increase

in Inhibitors,research,lifescience,medical endosome numbers per cell with increased time of exposure to SWCNTs, with a statistically significant increase in endosome number at 20 and 25 minutes [111]. In endocytosis independent pathway there is a direct translocation of CNT through the plasma membrane into the cytoplasm which has been termed by some researchers as the “nanoneedle” mechanism [100]. This pathway includes processes such as diffusion, membrane fusion, and direct pore transport Inhibitors,research,lifescience,medical (Figure 5(c)). Individually dispersed CNTs in aqueous solutions have been experimentally demonstrated to be able to enter the cytoplasm of cells by directly crossing the cell membrane. Such cellular uptake of CNT, which is not influenced by the presence of endocytosis inhibitor (such as sodium azide), suggests the endocytosis mafosfamide independent pathway of internalization [112]. The mechanism of how CNT enters cells via the insertion and diffusion is poorly understood. Some theoretical studies suggest a two-step process in which, first, the tubes accommodate onto the lipid cell membrane and then orient to adopt the transmembrane configuration. In this model, the internalization of nanotubes into the cells was spontaneous and was mediated by the lipid membrane and that the hydrophilic interactions and/or static charge interactions between the tubes and the lipid membrane which drove the translocation of the nanotubes [113].

5%) were the leading causes of unintentional injury deaths, while suicide was the leading cause of intentional injury and the second leading cause of injury deaths (23%) overall. Injuries represent the leading cause of death for persons under 40 years of age [2,3]. With close to 23 million disability-adjusted life years (DALYs) lost per annum (11.5% of all-cause DALYs), unintentional injuries represent a significant source of morbidity. Road traffic crashes account for one-third of these DALYs, followed by ‘other unspecified causes’ (29%), falls (17%), drowning (15%)

Inhibitors,research,lifescience,medical and poisonings (6%)[4]. An estimated 200 million persons are injured each year, with approximately one-third (62 million) requiring emergency care or hospitalisation

[5]. The consumption of health resources as a consequence of injury is significant. Direct medical Inhibitors,research,lifescience,medical costs have been estimated to be as high as CNY 64.1 billion RMB (USD$9.3 billion) per annum, with costs related to delay and absence from work being approximately CNY 6 billion (USD$0.8 billion)[5], equivalent to 1.92% of GDP (2007) [6]. Within this context of high injury rates and perceived limited available epidemiological data, commentators Inhibitors,research,lifescience,medical have identified the need for the establishment of population based injury Selleck SCH772984 surveillance systems to guide public health programs [3,7,8]. A number of fatality reporting systems and data sources do however exist, these being the National Statistics Yearbook, the Transportation Statistics Yearbook, and the Inhibitors,research,lifescience,medical Health Statistic Yearbook, the latter which reports mortality statistics for select causes of injury. While cause-of-death data leads to an understanding of changing disease patterns and permits population health policy planning, hospital-based injury surveillance systems and trauma registries facilitate prevention efforts as well as forming the basis of hospital quality assurance programs [9]. It has been noted that to date such systems have been limited in their scope within China [3,10,11]. Given the high incidence of injury in China and the calls for the establishment

broad based injury surveillance programs, it was PDK4 considered Inhibitors,research,lifescience,medical timely to document the extent to which injury surveillance studies have been conducted. Whilst also documenting the incidence and causes of injury for a wider audience, this Review aims to document existing research strengths as well as areas of surveillance systems research that require strengthening. Of particular interest was the extent to which the reporting of patient injury data is consistent with commonly accepted global reporting guidelines, and whether there is a need for broad-based injury surveillance and/or trauma registry systems to be implemented. In conducting this Review, there were two specific objectives: 1. To describe the characteristics of persons presenting to an emergency department following injury and the associated mechanisms of injury, and 2.

31-35 Inhibitor Library serotonin stores and transporter protein are important components of serotonin terminals, so that a combined deficit is a plausible indicator of reduced axonal branching and synapse formation.

With respect to abnormal serotonergic activity in functional ncuroimaging studies of patients with primary major depression, Sargent et al demonstrated reduced 5HT1A receptor binding potential of values in frontal, temporal, and limbic cortex with PET studies using [11C]WAY-1 00635 in both unmedicatcd and medicated depressed patients compared with healthy volunteers.24 Of note, binding potential values in medicated patients were similar to those Inhibitors,research,lifescience,medical in unmedicated patients. Drevets et al, using the same radioligand, reported a decreased binding Inhibitors,research,lifescience,medical potential of 5-HT1A receptors in mesial-temporal cortex and in the raphe in 12 patients with familial recurrent major depressive episodes, compared with controls.25 A deficit in the density or affinity of postsynaptic 5-HT1A receptors has been

identified in the hippocampus and amygdala of untreated depressed patients who committed suicide.26 In addition, impaired serotonergic transmission has been associated with defects in the dorsal raphe Inhibitors,research,lifescience,medical nuclei of suicide victims with major depressive disorder, consisting of an excessive density of serotonergic somatodendritic impulse-suppressing 5-HT1A autoreceptors.27 Similar abnormalities in 5-HT1A receptor

binding have been identified in patients with TLE. For example, in a PPT study of patients with TLE. using Inhibitors,research,lifescience,medical the 5-HT1A receptor antagonist ([18F] trans-4-fluro-N-2-[4-(2-methoxyphcnyl) piperazin-l-yl]ethyl-N-(2-pyridyl)cyclohexanecarboxamide), reduced 5-HT1A binding was found in mesial temporal structures ipsilateral Inhibitors,research,lifescience,medical to the seizure focus, in patients with and without hippocampal atrophy28 In addition, a 20% binding reduction tuclazepam was found in the raphe and a 34% lower binding in the ipsilateral thalamic region to the seizure focus. In a separate PET study aimed at quantifying 5HT1A receptor binding in 14 patients with TLE, decreased binding was identified in the epileptogenic hippocampus, amygdala, anterior cingulate, and lateral temporal neocortex ipsilateral to the seizure focus, as well as in the contralateral hippocampi, but to a lesser degree, and in the raphe nuclei.29 Other investigators using the 5-HT1A tracer, 4,2(methoxyphenyl)-1-α[2-(N-2-pyridinyl)-p-fluorobenza-midojcthylpipcrazinc ([18F]MPPF), found that the decrease in binding of 5-HT1A was significantly greater in the areas of seizure onset and propagation identified with intracranial electrode recordings.
