Abstract
Invasive aspergillosis (IA) is a common and deadly mold infection in immunocompromised patients. As morbidity and mortality of IA are primarily driven by poor immune defense, adjunct immunotherapies, such as chimeric antigen receptor (CAR) T cells, are direly needed. Here, we propose a novel approach to generate Aspergillus fumigatus (AF)-CAR T cells using the single-chain variable fragment domain of monoclonal antibody AF-269-5 and a lentiviral vector system. These cells successfully targeted mature hyphal filaments of representative clinical and reference AF isolates and elicited a potent release of cytotoxic effectors and type 1 T cell cytokines. Furthermore, AF-CAR T cells generated from peripheral blood mononuclear cells of four healthy human donors and expanded with either of three cytokine stimulation regimens (IL-2, IL-2 + IL-21, or IL-7 + IL-15) significantly suppressed mycelial growth of AF-293 after 18 hours of co-culture and synergized with the immunomodulatory antifungal agent caspofungin to control hyphal growth for 36 hours. Moreover, cyclophosphamide-immunosuppressed NSG mice with invasive pulmonary aspergillosis that received two doses of 5 million AF-CAR T cells (6 and 48 hours after AF infection) showed significantly reduced morbidity on day 4 post-infection (P < 0.001) and significantly improved 7-day survival (P = 0.049) compared with mice receiving non-targeting control T cells, even without concomitant antifungal chemotherapy. In conclusion, we developed a novel lentiviral strategy to obtain AF-CAR T cells with high targeting efficacy, yielding significant anti-AF activity in vitro and short-term protection in vivo. Our approach could serve as an important steppingstone for future clinical translation of antifungal CAR T-cell therapy after further refinement and thorough preclinical evaluation.IMPORTANCEInvasive aspergillosis (IA) remains a formidable cause of morbidity and mortality in patients with hematologic malignancies and those undergoing hematopoietic stem cell transplantation. Despite the introduction of several new Aspergillus-active antifungals over the last 30 years, the persisting high mortality of IA in the setting of continuous and profound immunosuppression is a painful reminder of the major unmet need of effective antifungal immune enhancement therapies. The success of chimeric antigen receptor (CAR) T-cell therapy in cancer medicine has inspired researchers to translate this approach to opportunistic infections, including IA. Aiming to refine anti-Aspergillus CAR T-cell therapy and improve its feasibility for future clinical translation, we herein developed and validated a novel antibody-based CAR construct and lentiviral transduction method to accelerate the production of CAR T cells with high targeting efficacy against Aspergillus fumigatus. Our unique approach could provide a promising platform for future clinical translation of CAR T-cell-based antifungal immunotherapy.

Abstract
Bladder cancer has a 60%-70% recurrence rate most likely due to any residual tumour left behind after a transurethral resection (TUR). Failure to completely resect the cancer can lead to recurrence and progression into higher grade tumours with metastatic potential. We present here a novel therapy to treat superficial tumours with the potential to decrease recurrence. The therapy is a heat-based approach in which bladder tumour specific single-walled carbon nanotubes (SWCNTs) are delivered intravesically at a very low dose (0.1 mg SWCNT per kg body weight) followed 24 h later by a short 30 s treatment with a 360° near-infrared light that heats only the bound nanotubes. The energy density of the treatment was 50 J cm-2, and the power density that this treatment corresponds to is 1.7 W cm-2, which is relatively low. Nanotubes are specifically targeted to the tumour via the interaction of annexin V (AV) and phosphatidylserine, which is normally internalised on healthy tissue but externalised on tumours and the tumour vasculature. SWCNTs are conjugated to AV, which binds specifically to bladder cancer cells as confirmed in vitro and in vivo. Due to this specific localisation, NIR light can be used to heat the tumour while conserving the healthy bladder wall. In a short-term efficacy study in mice with orthotopic MB49 murine bladder tumours treated with the SWCNT-AV conjugate and NIR light, no tumours were visible on the bladder wall 24 h after NIR light treatment, and there was no damage to the bladder. In a separate survival study in mice with the same type of orthotopic tumours, there was a 50% cure rate at 116 days when the study was ended. At 116 days, no treatment toxicity was observed, and no nanotubes were detected in the clearance organs or bladder.

Abstract
Normal and dying cells release various types of membrane-bound vesicles including microvesicles, exosomes, and apoptotic bodies. These vesicles play important roles in intercellular communication and signal transduction. However, their diverse forms and subtypes fluctuate in size and other properties. In result current purification approaches do not fully discriminate between different categories of extracellular vesicles. Here, we present a fluorescence technique that specifically identifies apoptotic bodies in preparations of microvesicles, exosomes, and other extracellular vesicles.The approach exclusively labels the vesicles that contain DNA with 5'PO4 blunt-ended DNA breaks, such as those produced by the apoptotic CAD nuclease during apoptotic DNA degradation. The technique can be useful in studies of apoptosis involving microvesicles and exosomes.

Abstract
Epigenetic alterations have been implicated in cancer development. DNA methylation modulates gene expression, which is catalyzed by DNA methyltransferases (DNMTs). The objective of our study was to evaluate expression of DNMTs in medulloblastoma and analyze its correlation with clinical features. Nuclear expression of DNMT1, DNMT3A and DNMT3B was analyzed in human primary medulloblastoma of 44 patients using immunohistochemistry. Correlation of expression of DNMT levels with classical histological subtypes, novel molecular subgroups and survival of patients was analyzed. Elevated expression of DNMT1, DNMT3A and DNMT3B was observed in 63.64%, 68.18% and 72.73% of all cases, respectively. None of them showed a correlation with classical histology or survival. Concerning molecular subtypes, significantly higher expression of DNMT1 was observed in the SHH group compared to non-SHH samples (p = 0.02), but without significant difference in DNMT3A or DNMT3B levels between any subtypes. In conclusion, DNMT1, DNMT3A and DNMT3B are highly expressed in human medulloblastoma samples, suggesting that promoter hypermethylation may play a role in medulloblastoma development. Demethylation of tumor suppressor gene promoters may be considered as a possible future target in therapy of medulloblastoma.

Abstract
A retrospective analysis of data from the European Rhabdoid Registry (EU-RHAB) was performed to describe the outcome of children with atypical teratoid/rhabdoid tumors (AT/RT) who underwent high-dose chemotherapy (HDCT) with auto-SCT. Nineteen patients (male, n=15; median age at diagnosis 21 months) were identified. Nine patients presented with metastatic disease at diagnosis. A partial or subtotal resection was achieved in 11, a total resection in five and a biopsy in three patients. Patients received a median of six chemotherapy cycles prior to HDCT. Additional radiotherapy was performed in 14 patients (first-line, n=9; following progression, n=5). Six patients underwent tandem auto-SCT. Disease status before HDCT was CR in six, PR in eight, stable disease in two and progressive disease (PD) in two patients (data missing, n=1). With a median follow-up of 16 months, 14 patients progressed. Estimated progression-free and OS at 2 years were 29% (±11%) and 50% (±12%), respectively. At last follow-up, eight patients were alive (first CR, n=4; second CR, n=2; PR, n=1; PD, n=1). Eleven patients died of PD. Median time-to-progression was 14 months. Selected patients with AT/RT might benefit from HDCT with radiotherapy. The definitive impact of this treatment modality has to be evaluated prospectively in a randomized trial.

Abstract
Cardiac CT scanning is the only non-invasive test capable of defining coronary anatomy and evaluating the degree and severity of coronary stenoses. We studied its application at La Tour hospital in Geneva: 108 patients had a cardiac CT scan in 2009. The main indication was the investigation of chest pain in patients with an intermediate risk profile. We confirmed that cardiac CT scanning tends to overestimate lesion severity, particularly when heavy calcification is present but has an excellent negative predictive value. Thanks to decreasing radiation exposure with new protocols and machines, cardiac CT scanning is fast becoming a useful option to evaluate coronary disease, especially when the pre-test probability is intermediate and/or functional testing is non conclusive.

Abstract
Background: Juvenile pilocytic astrocytomas (JPA), a subgroup of low-grade astrocytomas (LGA), are common, heterogeneous and poorly understood subset of brain tumours in children. Chromosomal 7q34 duplication leading to fusion genes formed between KIAA1549 and BRAF and subsequent constitutive activation of BRAF was recently identified in a proportion of LGA, and may be involved in their pathogenesis. Our aim was to investigate additional chromosomal unbalances in LGA and whether incidence of 7q34 duplication is associated with tumour type or location. Methods and results: Using Illumina-Human-Hap300-Duo and 610-Quad high-resolution-SNP-based arrays and quantitative PCR on genes of interest, we investigated 84 paediatric LGA. We demonstrate that 7q34 duplication is specific to sporadic JPA (35 of 53 – 66%) and does not occur in other LGA subtypes (0 of 27) or NF1-associated-JPA (0 of 4). We also establish that it is site specific as it occurs in the majority of cerebellar JPA (24 of 30 – 80%) followed by brainstem, hypothalamic/optic pathway JPA (10 of 16 – 62.5%) and is rare in hemispheric JPA (1 of 7 – 14%). The MAP-kinase pathway, assessed through ERK phosphorylation, was active in all tumours regardless of 7q34 duplication. Gain of function studies performed on hTERT-immortalised astrocytes show that overexpression of wild-type BRAF does not increase cell proliferation or baseline MAPK signalling even if it sensitises cells to EGFR stimulation. Conclusions and interpretation: Our results suggest that variants of JPA might arise from a unique site-restricted progenitor cell where 7q34 duplication, a hallmark of this tumour-type in association to MAPK-kinase pathway activation, potentially plays a site-specific role in their pathogenesis. Importantly, gain of function abnormalities in components of MAP-Kinase signalling are potentially present in all JPA making this tumour amenable to therapeutic targeting of this pathway.

Abstract
Interstitial cystitis (IC) is a chronic and painful bladder syndrome of unknown cause with no reliable biological marker or effective therapy. Vascular endothelial growth factor (VEGF), which plays a key role in bladder inflammation, is closely associated with the vascular alterations observed in patients with IC. However, our recent findings of VEGF receptors (VEGF-Rs) and VEGF coreceptors on nonendothelial cells in human and mouse urothelium suggest that additional VEGF targets and functions are possible in IC bladders. We report here that VEGF-Rs and coreceptors (neuropilins; NRP) are strongly expressed in both the human bladder urothelium and in the human bladder cancer cell line (J82) and that the expression of NRP2 and VEGF-R1 is significantly downregulated in IC compared with control subjects. In addition, treatment of J82 cells with bacillus Calmette-Guérin (BCG), a novel treatment strategy for IC, upregulates the messages for NRPs and VEGF-Rs. Furthermore, intravesical instillation of an internalizable VEGF fluorescent tracer (scVEGF/Cy5.5) into mouse urinary bladders results in a marked ligand accumulation in the urothelium and bladder parenchyma, indicating that urothelial VEGF-Rs are functionally active and capable of ligand interaction and internalization. Our results suggest that the VEGF pathway is altered in IC, that urinary VEGF may gain access to the bladder wall via these receptors, and that BCG treatment may replenish the missing VEGF-Rs/NRP receptors. Together, these results suggest that levels of NRPs, VEGF-Rs, and VEGF are new putative markers for the diagnosis of IC and that modulating these receptors can be exploited as therapeutic strategies.

Abstract
Short-term memory (STM), or the ability to hold verbal information in mind for a few seconds, is known to rely on the integrity of a frontoparietal network of areas. Here, we used functional magnetic resonance imaging to ask whether a similar network is engaged when verbal information is conveyed through a visuospatial language, American Sign Language, rather than speech. Deaf native signers and hearing native English speakers performed a verbal recall task, where they had to first encode a list of letters in memory, maintain it for a few seconds, and finally recall it in the order presented. The frontoparietal network described to mediate STM in speakers was also observed in signers, with its recruitment appearing independent of the modality of the language. This finding supports the view that signed and spoken STM rely on similar mechanisms. However, deaf signers and hearing speakers differentially engaged key structures of the frontoparietal network as the stages of STM unfold. In particular, deaf signers relied to a greater extent than hearing speakers on passive memory storage areas during encoding and maintenance, but on executive process areas during recall. This work opens new avenues for understanding similarities and differences in STM performance in signers and speakers.

Abstract
The transcription factor PU.1 plays a crucial role during normal haematopoiesis in both myeloid cells and B-lymphocytes. Mice with a disruption in both alleles of the PU.1 locus were found to lack macrophages and B cells and had delayed appearance of neutrophils. In addition, critical decrease of PU.1 expression is sufficient to cause acute myeloid leukaemia (AML) and lymphomas in mice. Recently, we reported that heterozygous mutations in the PU.1 gene are present in some patients with AML. Thus, we hypothesised that PU.1 mutations might also contribute to the development of acute leukaemias of the B-cell lineage. Here, we screened 62 patients with B-cell acute lymphoblastic leukaemia (B-ALL) at diagnosis for genomic mutations by direct sequencing of all five exons of the PU.1 gene. We found no genomic alteration of the PU.1 gene suggesting that PU.1 mutations are not likely to be common in B-ALL.

Abstract
The N-terminal domain of human apolipoprotein E (apoE-NT) harbors residues critical for interaction with members of the low-density lipoprotein receptor (LDLR) family. Whereas lipid free apoE-NT adopts a stable four-helix bundle conformation, a lipid binding induced conformational adaptation is required for manifestation of LDLR binding ability. To investigate the structural basis for this conformational change, the short helix connecting helix 1 and 2 in the four-helix bundle was replaced by the sequence NPNG, introducing a beta-turn. Recombinant helix-to-turn (HT) variant apoE3-NT was produced in Escherichia coli, isolated and characterized. Stability studies revealed a denaturation transition midpoint of 1.9 m guanidine hydrochloride for HT apoE3-NT vs. 2.5 M for wild-type apoE3-NT. Wild-type and HT apoE3-NT form dimers in solution via an intermolecular disulfide bond. Native PAGE showed that reconstituted high-density lipoprotein prepared with HT apoE3-NT have a diameter in the range of 9 nm and possess binding activity for the LDLR on cultured human skin fibroblasts. In phospholipid vesicle solubilization assays, HT apoE3-NT was more effective than wild-type apoE3-NT at inducing a time dependent decrease in dimyristoylphosphatidylglycerol vesicle light scattering intensity. In lipoprotein binding assays, HT apoE3-NT protected human low-density lipoprotein from phospholipase C induced aggregation to a greater extent that wild-type apoE3-NT. The results indicate that a mutation at one end of the apoE3-NT four-helix bundle markedly enhances the lipid binding activity of this protein. In the context of lipoprotein associated full-length apoE, increased lipid binding affinity of the N-terminal domain may alter the balance between receptor-active and -inactive conformational states.

Abstract
Osteoid osteoma and radiofrequency Osteoid osteoma relates to a benign skeletal neoplasm, smaller than 2 cm in diameter, composed of osteoid, highly vascularized connective tissue and surrounded by a ring of bone sclerosis. Its aetiology remains unknown. It affects twice more males than female patients and occurs usually between 5 and 40 years old. Long bones and spine are the most involved areas but the whole skeleton can be involved. Clinical manifestations can include local pain (increased at night and decreased by activity) and relief with salicylates administration. CT guided radiofrequency ablation of osteoid osteoma is in comparison to surgery less invasive, time saving and economic technique with excellent long term results.

Abstract
Phosphorylation of the membrane-cytoskeleton linker protein ezrin has been functionally linked to acid secretion and vesicle recruitment to the apical secretory membrane in gastric parietal cells. Phosphorylation of the conserved T567 residue of ezrin has been shown to alter the N/C oligomerization of ezrin and promote the formation of actin-rich surface projections in other cells. To test the importance of T567 as a regulatory site for ezrin in parietal cell activation, we incorporated wild-type (WT) and mutant forms of ezrin, including the nonphosphorylatable T567A mutation and a mutant mimicking permanent phosphorylation, T567D. All ezrin constructs included C-terminal cyan-fluorescent protein (CFP) and were incorporated into adenoviral constructs for efficient introduction into cultured parietal cells from rabbit stomach. Fluorescence microscopy was used to localize CFP-ezrin and monitor morphological responses. Accumulation of a weak base (aminopyrine) was used to monitor receptor-mediated acid secretory response of the cultured cells. Similar to endogenous ezrin, WT and T567A CFP-ezrin localized heavily to apical membrane vacuoles with considerably lower levels associated with the surrounding basolateral membrane. Interestingly, H,K-ATPase within cytoplasmic tubulovesicles was incorporated into the apical vacuoles along with WT and T567A mutant ezrin. In these parietal cells secretagogue stimulation produced a striking vacuolar expansion associated with HCl secretion and the secretory phenotype. Expression of T567D CFP-ezrin was quite different, being rarely associated with apical vacuoles. T567D was more typically localized to the basolateral membrane, often associated with long spikes and fingerlike projections. Moreover, the cells did not display secretagogue-dependent morphological changes and, to our surprise, H,K-ATPase was recruited to the T567D CFP-ezrin-enriched basolateral projections. We conclude that T567 phosphorylation, which is probably regulated through Rho signaling pathway, may direct ezrin to membrane-cytoskeletal activity at the basolateral membrane and away from apical secretory activity. The large basolateral expansion is predicted to recruit membranes from sources not normally targeted to that surface.

Abstract
The most effective treatment for hepatitis C virus (HCV) is interferon-alpha (IFN) therapy in combination with ribavirin. Although symptoms of depression are among the most common side effects of IFN therapy in treating patients with HCV, the mechanisms by which IFN produces these neuropsychiatric side effects remain unclear. In the brain, IFNs are involved in a number of regulatory functions, including but not limited to regulation of the endocrine system via the hypothalamic-pituitary-adrenal and -thyroid axes. The purpose of this study was to assess the effect of IFN therapy on thyroid function and to characterize the relationship between thyroid dysfunction and major depressive disorder during IFN therapy in patients with hepatitis C. Thirty-three patients with HCV were administered the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) Axis I Disorders (SCID) and completed the Beck Depression Inventory (BDI). Patients were on IFN for an average of 6 to 12 months depending on their viral genotype. Serum samples were collected at baseline, during and after IFN therapy, and measured for free thryoxine (FT4) and TSH levels. Patients who developed IFN-induced depression were treated with selective serotonin reuptake inhibitor antidepressants. Only one patient developed transient IFN-induced overt hypothyroidism, but he did not develop depression. Analysis of variance showed that there were no significant differences in either FT4 or TSH serum levels between patients who developed major depressive disorder (MDD) (no.= 10) during IFN therapy and those who did not (no.=23). These results illustrate the frequency and severity of depressive symptoms associated with IFN therapy and the apparent absence of a relationship between IFN-induced MDD and changes in thyroid function.

Abstract
Abstract
When suspended in methylcellulose, primary mouse keratinocytes cease proliferation and differentiate. Suspension also reduces the activity of the cyclin-dependent kinase cdk2, an important cell cycle regulatory enzyme. To determine how suspension modulates these events, we examined its effects on wild-type keratinocytes and keratinocytes nullizygous for the cdk2 inhibitor p21Cip1. After suspension of cycling cells, amounts of cyclin A (a cdk2 partner), cyclin A mRNA, and cyclin A-associated activity decreased much more rapidly in the presence than in the absence of p21Cip1. Neither suspension nor p21Cip1 status affected the stability of cyclin A mRNA. Loss of p21Cip1 reduced the capacity of suspended cells to growth arrest, differentiate, and accumulate p27Kip1 (a second cdk2 inhibitor) and affected the composition of E2F DNA binding complexes. Cyclin A-cdk2 complexes in suspended p21+/+ cells contained p21Cip1 or p27Kip1, whereas most of the cyclin A-cdk2 complexes in p21−/− cells lacked p27Kip1. Ectopic expression of p21Cip1 allowed p21−/− keratinocytes to efficiently down-regulate cyclin A and differentiate when placed in suspension. These findings show that p21Cip1 mediates the effects of suspension on numerous processes in primary keratinocytes including cdk2 activity, cyclin A expression, cell cycle progression, and differentiation.

Abstract
Interferon (IFN) therapy has been associated with the development of Major Depressive Disorder (MDD) when given to patients with hepatitis C (HCV). The incidence, time course, risk factors, and treatment of IFN-induced MDD are poorly understood. The objectives of the present study were to determine the incidence of IFN-induced MDD, as well as to determine the efficacy of open-label antidepressant treatment, in particular selective serotonin reuptake inhibitors (SSRIs) for IFN-induced MDD. Thirty-nine HCV patients on IFN therapy were monitored weekly using the Beck Depression Inventory (BDI). Those who became depressed were treated with citalopram, a SSRI antidepressant. Main outcome measures included the incidence of IFN-induced MDD, as well as response rates to antidepressants in those patients who developed IFN-induced MDD. Our results showed that 13 of 39 patients (33%) developed IFN-induced MDD. There were no differences in age, gender, past history of MDD, or substance use between those who became depressed and those who did not. However, there were significantly fewer African American patients in the depressed group. Patients who developed IFN-induced MDD were on IFN therapy for an average of 12.1 weeks prior to the development of MDD. Eleven of 13 patients (85%) were responsive to antidepressant treatment. We conclude that IFN-induced MDD is common in HCV patients. Health care providers should follow IFN-treated HCV patients for the development of MDD, particularly between the 2nd and 5th months of IFN therapy. SSRIs, in particular citalopram, are an effective treatment for IFN-induced depression in HCV patients.

Abstract
Resistance to thyroid hormone (RTH) is a syndrome in which patients have elevated thyroid hormone (TH) levels and decreased sensitivity to its action. We describe a child with extreme RTH and a severe phenotype. A 22-month-old female presented to the NIH with goiter, growth retardation, short stature, and deafness. Additionally, the patient had hypotonia, mental retardation, visual impairment, and a history of seizures. Brain magnetic resonance imaging showed evidence of demyelination and bilateral ventricular enlargement. The patient had markedly elevated free T3 and free T4 levels of more than 2000 pg/dl (normal, 230-420 pg/dl) and more than 64 pmol/liter (normal, 10.3-20.6 pmol/liter), respectively, and TSH of 6.88 mU/liter (normal, 0.6-6.3 mU/liter). These are the highest TH levels reported for a heterozygous RTH patient. A T3 stimulation test confirmed the diagnosis of RTH in the pituitary and peripheral tissues. Molecular analyses of the patient's genomic DNA by PCR identified a single base deletion in exon 10 of her TRbeta gene that resulted in a frameshift and early stop codon. This, in turn, encoded a truncated receptor that lacked the last 20 amino acids. Cotransfection studies showed that the mutant TR was transcriptionally inactive even in the presence of 10(-6) M T3 and had strong dominant negative activity over the wild-type receptor. It is likely that the severely defective TRbeta mutant contributed to the extreme RTH phenotype and resistance in our patient.

Abstract
OBJECTIVE In this preliminary study, we examined the relationships between prior course and severity of illness and size of the hippocampus, temporal lobes, and third and lateral ventricles in patients with bipolar disorder. BACKGROUND The few studies that have investigated relationships between course of illness measures and neuroanatomic structures in patients with bipolar disorder found divergent results. METHOD Twenty-six outpatients, who met Diagnostic and Statistical Manual, Third Edition - Revised (DSM-III-R) criteria for bipolar disorder, received a magnetic resonance imaging (MRI) scan, from which volumes of the temporal lobes, hippocampi, third ventricle, and areas of the lateral ventricles were calculated. Prior course of illness variables were determined using the NIMH Life-Chart Method and were correlated to the volumetric measures of neuroanatomic structures using multiple regression analyses. RESULTS A longer duration of illness was paradoxically associated with a larger left temporal lobe volume whether patients with a history of substance abuse were removed from the analyses. CONCLUSIONS Additional studies are needed to both replicate and further examine the association of prior course of illness and larger hippocampal and ventricular volumes in bipolar disorder.

Abstract
OBJECTIVE There have been relatively few quantitative MRI studies of temporal lobe structures and the lateral ventricles in bipolar patients and a lack of agreement across studies as to whether these structures differ significantly in size from control subjects. Also there have been no quantitative MRI studies of bipolar II patients. The present study measured temporal lobe and ventricular structures in both bipolar I and bipolar II patients, as well as control subjects. METHOD Twenty-five bipolar I patients, 22 bipolar II patients and 19 control subjects underwent MRI brain scans. The 5 mm coronal slices of each subject were coded and measured by a rater who was blind with respect to subject diagnosis. Volume estimates of the temporal lobe and hippocampus were calculated for each hemisphere by measuring the area of the structure in each slice in which it appears, multiplying by 5 mm and summing. In addition to these volume estimates, the area of the lateral ventricle and the inferior horn of the lateral ventricle, the lateral ventricle to cerebrum area ratio (LV/C) and the temporal lobe to cerebrum area ratio (TL/C), were calculated for each hemisphere in one reference slice only. The area of the third ventricle was also measured. Volume estimates and area ratios were then compared among diagnostic groups. RESULTS There were no significant differences in temporal lobe or hippocampal volume estimates, in the third ventricle and inferior horn of the lateral ventricle area measurements, and in the TL/C area ratio among diagnostic groups. The lateral ventricle area and LV/C area ratio were significantly larger in bipolar I patients than either bipolar II patients or control subjects only in the left hemisphere. Furthermore, these measures were approximately twice as large in the bipolar I patients as the other groups. CONCLUSIONS The current study adds to a growing literature that bipolar I disorder, particularly in males, may show different neurobiological alterations compared to bipolar II patients or control subjects. The pathophysiologic implications of this accumulating evidence of increased left ventricular size in bipolar I disorder remains to be further elucidated.

Abstract
This study was undertaken to test the hypothesis that a specific pathophysiological mechanism of diabetic neuropathy, namely increased polyol pathway flux, could be operative in patients with bipolar and unipolar mood disorders. Numerous studies have shown abnormalities of carbohydrate metabolism, including high rates of diabetes mellitus, in patients with mood disorders. Several studies have found that peripheral neuropathy is a risk factor for depression in diabetics. Furthermore, increased polyol pathway flux results in elevated sorbitol concentrations in peripheral tissues and cerebrospinal fluid (CSF) of diabetics with neuropathy. The purpose of this study was to determine whether sorbitol concentration is elevated in the CSF of non-medically ill patients with mood disorders. Lumbar punctures were performed on 30 subjects - 10 with bipolar mood disorder, 10 with unipolar mood disorder, and 10 age-matched normal controls, and CSF sorbitol concentrations were measured, using a gas chromatographic-mass spectroscopic technique. The mean+/-standard deviation of CSF sorbitol concentrations differed among the three groups as follows: bipolar (22.9+/-4.6 micromoles/l) > unipolar (19.0+/-2.8 micromoles/l)>normal control (15. 6+/-1.9 micromoles/l). One-way ANOVA showed significant (P=0.0002) differences among the three groups. Post-hoc tests indicated a significant (P<0.05) difference between bipolars and normal controls, bipolars and unipolars, and unipolars and normal controls. Further investigation is needed to determine the pathophysiological significance of this novel finding of elevated sorbitol concentration in the CSF of patients with mood disorders.

Abstract
Twelve cases of neuroblastoma (NB) (7 boys and 5 girls) and 4 cases of primitive peripheral neuroectodermal tumor (PNET) (3 boys and 1 girl) were investigated for the presence of apoptosis and retinoic acid receptor (RAR) by immunhistochemical method. The apoptotic index in NB was zero or 1% in 8 children and relatively low (2-4.8%) in the other 4 cases, while it was higher (4.1-10.5%) in PNET. The RAR index determined by immunoperoxidase reaction in NB was zero or 3% in 5 cases and 9-34% in 7 children. RAR index in PNET was 16-68% in all the 4 cases. Good correlation (r = .47 according to Pearson-Bravis) was found between the number of RAR and spontaneous apoptosis. These results suggest that the RAR index in untreated NB and PNET shows great individual variation since its determination is necessary for the evaluation of the efficacy of retinoic acid treatment.
