Comparative analysis of gene

expression in ill and well persons, followed by study of genes with differential expression in ill persons. Positional strategies: – whole-genome association (Sorafenib price linkage disequilibrium) with densely spaced markers and/or/followed by mutational analysis; – positional cloning (detection of linkage, followed by association and mutational analysis of genes within the linkage region). Positional approaches based on linkage are currently in some disfavor, yet the recent success in type 2 diabetes (see Inhibitors,research,lifescience,medical below) , a common disease with similar inheritance to psychiatric disorders, belies the current disfavor. This review selectively focuses on a positional strategy, because such strategies exhaust all possibilities and thus have the capacity to uncover susceptibility genes that are surprises (ie, for which there is no prior hypothesis). Linkage followed Inhibitors,research,lifescience,medical by association (as opposed to genomewide association) is currently a feasible positional strategic choice. This is not to suggest that other strategies might not, in the Inhibitors,research,lifescience,medical end, prove more successful in finding susceptibility mutations. The scientific advances supporting the positional strategy include the following. Completion of the finished sequence phase of the Human Genome Project The Human Genome Project has made enormous contributions to the various maps of the human genome, including

Inhibitors,research,lifescience,medical genome-wide physical maps, very dense polymorphism maps, and integrated transcript maps. Sufficient single nucleotide polymorphisms (SNPs) for very dense mapping at almost all locations in the genome have also been developed. The genome project is now rapidly nearing its complete annotated sequence goal. This enables the genomic sequence of

any gene to be examined in blood or other specimens from any individual. An ability to do mutational analysis of any gene or group of genes is a vast advance over what has been so often done in psychiatry until now – testing one or a few polymorphisms of a gene, and Inhibitors,research,lifescience,medical generalizing from that result. Recent scientific developments supporting the feasibility of cloning genes for complex disorders, based on initial Cediranib (AZD2171) linkage findings The discovery of susceptibility genes for the major psychiatric disorders, BP and SZ, is thought to include some of the most intractable current problems in human genetics.1 The outlook for major advances based on genetic linkage and linkage disequilibrium has now greatly improved. The very recent availability of very dense SNP and other polymorphism maps has greatly improved the statistical power to detect linkage disequilibrium. Statistical methods developed in recent years for linkage and for combined linkage and linkage disequilibrium analyses, including haplotype-based analyses,2-6 are capable of teasing apart subtle genetic components contributing to common diseases with complex inheritance.

Behavioral studies have been conducted to examine whether there are deficits in executive control of attention in ASD using cognitive paradigms such as the Go/No-Go and the Stroop tasks. Although executive control dysfunction may be attributed to frontal lobe abnormalities that have been observed in individuals with autism (Courchesne et al. 2001; Sparks et al. 2002), there is no consistent evidence supporting impaired inhibition, for example, on the Stroop task (Russell et al. 1999) or the Go/No-Go task (Ozonoff Inhibitors,research,lifescience,medical and McEvoy 1994). One study, examining conflict processing, found no group differences in mean ACC

activation during functional magnetic resonance imaging (fMRI); however, the results indicated an abnormal time course of the hemodynamic response in this region during conflict conditions (Dichter and Belger 2007). Evidence also suggests abnormal functional connectivity between Inhibitors,research,lifescience,medical ACC and other important regions in ASD (Welchew et al. 2005; Kana

et al. 2007). Abnormal behavioral performance in conflict processing, significant metabolic reduction in the ACC (Haznedar et al. 1997), and abnormal ACC activation Inhibitors,research,lifescience,medical and connectivity together suggest a prominent role of the ACC in impaired executive control in ASD. Recent results suggest that the three attentional networks communicate with and influence one another to Dolutegravir manufacturer support the functional integration and interaction of attention (Fan et al. 2009). The overfocused or selective attention found in individuals with autism (Lovaas et al. 1979) may reflect abnormal interactions among attentional networks and core deficits of executive control, rather than a narrowed spotlight of visuospatial Inhibitors,research,lifescience,medical attention. Most prior studies on this topic were conducted using separate tasks not designed to investigate interactions among attentional networks. Thus, interactions among attentional networks in individuals with ASD compared with

healthy controls (HCs) would seem to be a particularly important area of examination. We examined the functions Inhibitors,research,lifescience,medical and neural mechanisms of the three attentional networks in individuals with ASD using the Attention Network Test-Revised (ANT-R) (Fan et al. 2009), probing new attentional functions and allowing analysis of the functional integration and interaction of the attentional networks. We hypothesized deficits in the alerting, orienting, and executive control networks, and abnormal interaction among these networks in the ASD group relative to HCs. Method Participants All eligible participants underwent a diagnostic evaluation consisting of psychiatric, medical, and developmental assessment (see Table 1 for demographic and clinical data). Intelligence quotient (IQ) was measured using the Wechsler Adult Intelligence Scale, third edition (WAIS-III) (Wechsler 1997).

I think that it is those kinds of cases that are more salient in my mind. (Physician)” Second, participants noted that poor discharge planning placed an undue burden on community agencies ill-equipped to provide end-of-life care services. Participants reported that homeless persons were frequently discharged directly to emergency shelters even though these settings could provide only limited Inhibitors,research,lifescience,medical care to clients with complex medical needs. For example: “There is no discharge planning for this population. They are pushed

out of the hospitals to make room for beds because there are bed shortages. They do very little in the way of planning to discharge homeless people. They are easily

shoved to the street or shelter…You have incidents where you are having people dropped off [at the emergency shelter] by ambulance. Over the last month, they have been a little bit more courteous in calling. I think that has to do with Inhibitors,research,lifescience,medical the recent death of this fellow but I won’t bet that it will continue Inhibitors,research,lifescience,medical because there doesn’t seem to be a lot of continuity there. (Shelter director)” Participant recommendations to improve the end-of-life care system Low-threshold strategies Participants strongly recommended that the end-of-life Inhibitors,research,lifescience,medical care system adopt low-threshold approaches, which have minimal requirements for admission and care. Participants emphasized that conventional approaches requiring drug or alcohol abstinence restricted access to end-of-life care services for substance-using homeless populations. Participants reported that it was important that end-of-life care providers acknowledge that changes to rules and regulations were needed for the purpose of serving this population. Some participants noted that integrating harm reduction strategies for alcohol

Inhibitors,research,lifescience,medical use (i.e. prescribing alcohol and managing intake) and illicit drug use (i.e. providing clean needles and permitting off-site illicit drug use) were low-threshold strategies with the potential to improve end-of-life care services for this population. These participants observed that, although Furthermore, many participants almost articulated that this adoption of harm reduction strategies expressed a commitment to serving homeless persons and awareness of this population’s life circumstances. For example: “People died Epigenetic inhibitor solubility dmso outside on the streets because [end-of-life care providers] couldn’t provide that. We agreed to walk outside on the street with these people. [Harm reduction] is part of walking down the road, so that they don’t go out and drink Listerine.

17-19 Thus, more damage will affect the heart valves due to the lack of nTreg cells at the inflammatory sites in the heart tissues. Results showed that cultured cells produced high levels of TNF-α in culture supernatant (table 1). These results may correlate with that. TNF-α is the main mediator of inflammatory processes in RF and RHD in response to GAS antigen especially M protein. Many studies suggest that streptococcal M protein interacts with TLR-2 on human peripheral blood monocytes. As a consequence

of monocytes activation by M proteins, monocytes Inhibitors,research,lifescience,medical express the cytokines IL-6, IL-1β, and TNF-α.20 Another study,21 found that TNF-α inhibited the suppressive function of both naturally occurring CD4+CD25+ Tregs and transforming growth factor–beta1 (TGF-β1)-induced CD4+CD25+ T-regulatory cells. Thus, our results revealed that the impairment of the function of nTreg cells and the development Inhibitors,research,lifescience,medical of heart damage in RHD patients may occur in two pathways. First, TNF-α can inhibit nTreg cells during the acute stage of rheumatic myocarditis

and in the recurrent inflammatory attacks Inhibitors,research,lifescience,medical during the chronic stage. Secondly, the low amount of IL-4 in chronic rheumatic myocarditis will alter the nTreg cells under certain conditions, or other cytokines like B cell activation factor of the TNF family (BAFF) can play a role. BAFF-expanded CD4+CD25+Foxp3+ regulatory T cells (Tregs) were consistent with an find more ability to home to inflammatory sites and prevent T cell effector responses.22 Therefore, autoimmune rheumatic myocarditis process will depend to a great degree on cellular immunity rather than humoral immune response. The very important role for nTreg cells in Inhibitors,research,lifescience,medical reversing this autoimmunity will take place to further directions towards the prevention of rheumatic myocarditis. Conclusion The findings of this study revealed that streptococcal M protein has the ability to stimulate both of

CD4+ T cells and CD4+CD25+ nTreg cells. It caused the proliferation of both cells Inhibitors,research,lifescience,medical and the production of TNF-α from CD4+ T cells. Moreover, the findings show that M protein has an inhibitory effect on expanded CD4+CD25+ nTreg cells function resulting in the inability of CD4+CD25+ nTreg cells to suppress the autoreactive CD4+ T cells, which play the major role GPX6 in the development of rheumatic heart damage. Also, the findings may reinforce the role of streptococcal M protein in the pathogenesis of RHD.

Dear Editor, I did read the paper “The knowledge, attitude and behavior of HIV/AIDS patient’s family toward their patients before and after counseling” in a recent issue of IJMS.

Regions of the frontal cortex project to the caudate or putamen in segregated, parallel neuronal pathways. Within the basal ganglia, these projections arc propagated to related

downstream structures, including specific thalamic nuclei, and then project, back to the discrete frontal cortex regions. Since the basal ganglia have a diversity of neurotransmitters and modulators, and are richly innervated by diverse brain structures, there is ample opportunity within these pathways to capture significant regional influence and to subsequently modulate frontal cortical function. Any abnormality in the dopaminergic dynamics,83 Inhibitors,research,lifescience,medical the balance of neurotransmitter function in the basal ganglia,76 or the influence of the thalamus65 could alter frontal cortical function through these pathways. Neurodevelopmental factors The idea that schizophrenia is a neurodevelopmental illness, whose pathology is already set at birth Inhibitors,research,lifescience,medical and only expresses itself as psychosis later, has become popular. This formulation of illness onset explains the influence of pre- or perinatal events and the evidence of premorbid cognitive predictors of illness onset. Nonetheless, the course of schizophrenia does not. conform to that of a traditional neurodevelopmental illness, like

mental retardation, whose symptoms Inhibitors,research,lifescience,medical appear at birth. However, it has Inhibitors,research,lifescience,medical been argued that the neural apparatus subserving schizophrenia does not mature until late teens, and cannot fully express its dysfunction before this. Another caveat is that there is actually scant biological evidence to support the neurodevelopmental formulation.

Also, it. is not. the case that all forms of schizophrenia need to be based on the same etiology, even if they involve the same pathophysiology. Hence, neurodevelopmental aspects may be important in some, but not all, forms of schizophrenia. Inhibitors,research,lifescience,medical Limbic cortex Experimental modalities beyond brain imaging have advanced our understanding of the pathophysiology of schizophrenia. These include postmortem tissue studies and animal, Terminal deoxynucleotidyl transferase model experiments. ABT-888 supplier Findings from postmortem brain studies in schizophrenia are reviewed in this issue by Harrison et al.85 From the substantial body of postmortem work reviewed, several guiding formulations emerge: (i) the limbic system has been consistently identified as affected in schizophrenia; and (ii) although the examination of postmortem transmitter systems has been skewed toward the monoamines and dopamine in particular, it. is clear that many chemical systems are affected in schizophrenia.76 In accounting for a demonstrated abnormality, separating cause and effect of the psychotic condition is always critical and, at present, a matter of hypothesis.

Fig. 1 Transesophageal Gefitinib solubility dmso echocardiography (A and B) showed highly 76 mobile thrombus in the dilated right atrium, and duplex-Doppler scanning (C) revealed suboclusive thrombosis (*) of the left subclavian vein. RA: right atrium, RV: right ventricle, LA: left atrium, … Recent clinical practice guidelines confirm that thrombolytic therapy is the first-line therapy for high-risk PE, and heparin the first-line therapy for non-high-risk PE.1) Routine use of thrombolysis in non-high risk PE patients is not recommended, but may be considered in selected patients with intermediate-risk after Inhibitors,research,lifescience,medical thorough consideration of contraindications.1) PE patients at higher risk of death,

despite the absence of systemic arterial hypotension and cardiogenic shock, are those with right ventricular dilatation and hypokinesis or akinesis on echocardiography, right heart thrombi, pulmonary arterial systolic pressure > 50 mmHg, age > 70 years, and elevated troponin level.1),2) Patients with PE and right heart thrombi have a very poor short

term prognosis with early Inhibitors,research,lifescience,medical mortality of 44%, despite their clinically stability, primarily because these highly mobile, poorly fixed clots are at high risk for fatal re-embolisation.3) In our case, additional Inhibitors,research,lifescience,medical reason for thrombolytic therapy was massive thrombus revealed in left subclavian vein. In that case, thrombolytic therapy lead to a simultaneous lysis of the thrombus in the deep vein system as well as those in the right heart and pulmonary arteries, resulting in clinical improvement and decreased re-embolization risk. Therefore, echocardiography confirmation of the right heart thrombi is a clear reason for early thrombolysis even in clinically

Inhibitors,research,lifescience,medical stable patients with intermediate-risk PE, if absolute contraindications Inhibitors,research,lifescience,medical for thrombolytic treatment are not exist.
A 53-year-old woman was admitted to our hospital due to right pleuritic chest pain, accompanied with hemoptysis, fever and chilling sensation for 3 days. Her blood pressure was 120/80 mmHg, pulse rate was 87 beats per minute and body temperature was 37.1℃. On physical examination, crackle was heard in the right lower lung Bay 11-7085 field and she complained tenderness in right chest wall. Her heart beat was regular and murmur was not auscultated. The electrocardiogram showed normal sinus rhythm with heart rate 79 beats per minute. On laboratory examination, cardiac enzymes were normal, white blood cell count was slightly elevated (13530/mm3), erythrocyte sedimentation rate (22 mm/hr) and C-reactive protein (3.62 mg/L) were within normal range. Plain chest X-ray showed soft tissue fullness at right infra-hilar area and air-fluid level in right lower lung field (Fig. 1A). Chest CT revealed cavitary lung mass in the right lower lobe and multiple lymphadenopathies in right side mediastinum (Fig. 1B and C). Bronchoscopy revealed multiple nodules at right intermediate bronchus and right second carina.

Among clopidogrel-treated subjects in the TRITON–TIMI 38 trials, carriers had a relative increase of 53% in the composite primary efficacy outcome of the risk of death from cardiovascular causes, myocardial infarction, or stroke, as compared with non-carriers.11 AHA/ACCF RESPONSE TO THE FDA ABT-888 solubility dmso warning The warning sent out by the FDA coincided with the start of the annual meeting of the American College of Cardiology (ACC), where 20,000 cardiovascular professionals were gathered. All those present at the meeting received an e-mail alert from the FDA stating: “The FDA issues a boxed warning for CYP2C19-linked poor

metabolism Inhibitors,research,lifescience,medical of Plavix.” Since all the physicians at the meeting had patients who were being treated with Plavix, they were immediately inundated with a barrage of e-mails from their patients, their patients’ families, and their Inhibitors,research,lifescience,medical patients’ lawyers, all concerned about this warning.

As a response to the FDA warning, a committee was immediately convened and set out to provide guidance for all the physicians who had to deal with the aftermath of the boxed warning. The committee comprised experts Inhibitors,research,lifescience,medical from the American College of Cardiology Foundation (ACCF) and the American Heart Association (AHA). The findings of this committee were published 2 months after the FDA warning.12 The main findings were that there is substantial individual variability in the response to clopidogrel, which may be due to pharmacokinetic (PK) or pharmacodynamic (PD) differences. These differences are due Inhibitors,research,lifescience,medical to a number of factors such as age, body mass

index, co-morbidities such as diabetes and dyslipidemia, and other unidentified factors. Genetic variability plays a role as well, but it explains only a small portion of the variability seen. The role of genetic variability was seen in a study done on a homogenous population of healthy Amish adults (Pharmacogenomics of Antiplatelet Intervention—PAPI). In this study, a gene dose effect of CYP2C19*2 on clopidogrel reduction of ADP-induced platelet aggregation was seen. However, the genotype variability only accounted for 12% of the variability in clopidogrel response.13 In addition, other Inhibitors,research,lifescience,medical genetic variations may also affect the PK, PD, and clinical efficacy of clopidogrel. There are additional CYP genes such as 2C19, 2C9, 2B6, 3A4, 3A5, and 1A2. The adenosine triphosphate-binding cassette containing gene ABCB1, also known as the out multidrug resistant (MDR1) gene, was shown to affect the metabolism of this drug as well. Large differences in the bioavailability of clopidogrel were seen among carriers of the wild-type gene as compared with those carrying the mutated form.14 Point-of-care assays for these genetic mutations were not available at the time when this article was being written. In addition, the positive predictive value of CYP2C19 loss-of-function genetic polymorphisms is estimated to be between 12% and 20% in patients who have acute coronary syndrome (ACS) and are undergoing percutaneous coronary interventions (PCIs).

Given the variability of recurrence risks observed in the family studies and the clinical heterogeneity that is evident in OCD, this result is not surprising. Nevertheless, it is noteworthy that the conclusions of the authors in all of these reports were that there are some genes of major effect important for the manifestation of OCD. Given the variability in the estimates of recurrence risks in the reported studies, it is quite likely that OCD is an oligogenic disorder (ie, a number of genes are important for the expression of the disorder). In addition to advances in understanding

regarding familiality and genetic mechanisms that are likely to be Inhibitors,research,lifescience,medical involved in OCD, there have also been dramatic gains in our understanding of the phenotype of OCD. Perhaps most important for genetic research are new ways to assess the phenotype dimensionally, moving beyond traditional categorical diagnostic classifications. Over Inhibitors,research,lifescience,medical the last decade, results from a number of independent

studies have demonstrated that there are different clusters of symptoms that comprise the OCD phenotype73-77 and that they appear to be heritable.73,76 It follows then that there may be several genes that could influence Inhibitors,research,lifescience,medical the different components of OCD. Candidate gene studies Given current theoretical understanding of mechanisms that may be implicated in the emergence and maintenance of OCD symptoms and the treatment of the disorder, a number of investigators have pursued genetic studies of specific genes that are known to be involved in systems implicated in the pathogenesis of OCD. In particular, because of the efficacy of serotonin reuptake in treating OCD,78-79 a number of genes important in the serotonergic system have been examined. In addition, genes in the dopaminergic, Inhibitors,research,lifescience,medical glutamatergic, and opioid systems have also been studied to determine if they also contribute to the risk Inhibitors,research,lifescience,medical of OCD.80 Over 80 candidate gene studies have been published over the last decade (Table III) . As noted above, association studies have examined candidate genes that function

within the serotonergic and dopaminergic systems and more recently the glutamatergic system based on knowledge of the pathophysiology and pharmacology of OCD. However, with the exception of the glutamate transporter gene SLCL1A1,81-84 none have been consistently replicated. GPX6 While some of the more recent published studies have larger Talazoparib mw sample sizes, all have inadequate sample sizes to achieve genome -wide significance (ie, 5×10-8). Some recent studies have moved beyond simply documenting that individuals with OCD are more likely to have a specific allele or candidate gene that other nonaffected individuals (ie, association studies) and have begun to explore the function of some of the genes being studied. Preliminary results suggest that may be a promising approach.85 However, none of these studies have yet been replicated, so it is too early to reach any definite conclusions.

The aggregated culture contains multiple layers of cells, making it difficult for the testing reagents and antibodies to access the cultured cells for later quantification. Recently, a dissociated neuron-OL co-culture model from mouse embroynic spinal cord

has been described (Thomson et al. 2008). Interestingly, the authors noted also that such culture derived from embryonic rat spinal cord tissue failed to myelinate. Here, we described a novel modified Inhibitors,research,lifescience,medical neuron-OL co-culture rat model that can be utilized to investigate the mechanisms of CNS-related myelin deficits. Material and Methods Chemicals Dulbecco’s modified Eagle Medium (DMEM)/Ham’s F12, neural basal medium (NBM), B27 supplement, 7.5% bovine serum albumin (BSA), Hank’s Balanced Inhibitors,research,lifescience,medical Salt Solution (HBSS), and penicillin/streptomycin were purchased from Invitrogen (Carlsbad, CA, USA). Recombinant rat nerve growth factor (NGF), neurotrophin-3 (NT-3), tumor necrosis factor-α (TNFα), and interleukin-1β (IL-1β), were obtained from R&D system (Minneapolis, MN, USA). Normal horse and fetal bovine serum, insulin, transferrin, sodium selenium, progesterone, putrescine, GDC-0973 ic50 hydrocortisone, Inhibitors,research,lifescience,medical biotin, N-acetyl-L-cysteine, triiodothyronine (T3), L-α-Lysophosphatidylcholine (LPC) were

obtained from Sigma-Aldrich (St. Louis, MO, USA). Normal guinea pig serum was from EMD Chemicals (Philadelphia, PA, USA). The sources and specificity of primary antibodies are listed in Table 1. Second antibodies (biotin or fluorescein labeled) were obtained from Jackson ImmunoResearch Inhibitors,research,lifescience,medical Lab (West Grove, PA, USA). Table 1 Antibodies used in immunocytochemistry in this study Myelination co-culture The dissection of rat E16 spinal cord is similar to that described previously in mice (Thomson et al. 2008). Briefly, spinal cords from six embryos Inhibitors,research,lifescience,medical were collected in a petri dish containing

1 mL of 1× HBSS (without Ca2+ and Mg2+). After carefully removing the meninges, the spinal cord tissue was cut into small pieces using a surgical blade. The minced tissue were then transferred into a 15-mL centrifuge tube with 1 mL Trypsin-EDTA (Sigma #T4299) and incubated for 15 min at 37°C. The enzymatic reaction was stopped by mixing the tissue with 1.5-mL trypsin through inhibitor-DNase I solution (0.05% soybean trypsin inhibitor, 0.02% DNase-I, and 0.3% BSA in DMEM), and tissue suspension was centrifuged at 800 g for 5 min. The supernatant was replaced with 5-mL plating medium (50% normal horse serum and 20% 1× HBSS with Ca2+/Mg2+ in DMEM). Tissue was titrated with a 1-mL pipette tip for 10 times. The dissociated cell suspension was then passed through a 40-μm cell strainer. Total number of cells was counted by mixing one part of cell suspension with one part of trypan blue solution. The viable cells typically exceeded 80%. Cells were then seeded on poly-L-lysine-coated cover slips at a density of 0.4 × 105/cm2.

Two year survival rate was 90% in responders and 25% in non-responders using this criteria with p=0.002 (19). Uptake decrease during therapy is a continuous variable and different thresholds have been

determined by other investigators. For example, Shah et al found that a 45% cutoff comparing uptake after 35 days was the best value to separate responders from nonresponders and predict outcome (20). In evaluating response to treatment for esophageal carcinoma, studies have shown marked variability (from 10-80%) in the Inhibitors,research,lifescience,medical cutoff values determined retrospectively, and it seems likely that gastric cancer may have comparable variability (21). Wahl et al. have proposed a PET Response Criteria in Solid Tumors (PERCIST) analogous to and intended to eventually supercede other anatomic tumor response metrics such as the World Health Organization (WHO) criteria and multiple versions of the Response Evaluation

Inhibitors,research,lifescience,medical Criteria in Solid Tumors (RECIST) (22). Wahl notes that both qualitative and quantitative approaches have been made in using PET results for response assessment. Because Linsitinib statistically significant variability between SUV values is typical even when tested and retested under careful control, PERCIST criteria proposes a 30% or greater decline as indicative of “medically relevant beneficial changes”. Per the criteria, normal reference tissue values Inhibitors,research,lifescience,medical are designated within a scan by using a consistent protocol based on regions of interest in the liver and the most active tissues. Wahl suggests that the PERCIST criteria be used as a starting point for clinical trials and clinical reporting. This seems wise as the ad hoc approach to defining PET response has resulted in a body of work that is fragmented to the point of poor relevance.

Inhibitors,research,lifescience,medical Figure 2 CT-PET at diagnosis shows uptake in the proximal stomach. After therapy, uptake Inhibitors,research,lifescience,medical is visibly reduced. Many gastric cancers are not PET avid and repeat imaging will not provide additional useful imaging in these patients. Wahl recommends the use of RECIST 1.1 in such cases. Ott et al grouped patients with non-avid tumors as similar in prognosis to metabolic non-responders, that is, biologically unfavorable with poorer prognosis. Metabolic responders had a 69% histopathologic response rate while metabolic non-responders Mannose-binding protein-associated serine protease had only a 17% histopathologic response rate, similar to the 24% histopathologic response rate of the non-avid group. Survival was also similar between the non-avid group and the non-responding group while significantly different from the responding group (19). In addition to suggesting response criteria and prognosis groupings, Kim et al. have compared FDG -PET to fluorothymidine (FLT)-PET with interesting results. FLTPET had a higher sensitivity than FDG-PET and Ott suggests that it may provide a useful adjunct by providing a quantitative assessment of proliferation.
