Role and clinical implications of atypical antipsychotics in anxiety disorders, obsessive-compulsive disorder, trauma-related, and somatic symptom disorders: a systematized review

Atypical antipsychotics (AAs) may play a role in the treatment of anxiety disorders, obsessive-compulsive disorder (OCD), and trauma-related disorders. No reviews on their differential use in these different disorders have been performed recently. The aim of this systematized review was to obtain data on efficacy and comparative effectiveness of AAs as a treatment of anxiety disorders, OCD, and trauma-related disorders to provide guidance for clinicians on when and which AA to use. We searched on PubMed, Psychnet, and Cochrane Libraries from inception to July 2015. Search results were limited to randomized, placebo-controlled trials of adult patients. Evidence of efficacy was considered the presence of positive results in two or more double-blind placebo-controlled studies. Our systematized search identified 1298 papers, of which 191 were subjected to a full-text review and 56 were included. Quetiapine extended-release showed a role in both acute and maintenance treatment of uncomplicated generalized anxiety disorder, whereas more studies are needed before drawing practical recommendations on the use of olanzapine and risperidone; aripiprazole and risperidone are effective in resistant OCD as augmentation treatments. Risperidone and olanzapine add-on may have a role in resistant or chronic post-traumatic stress disorder patients, although only risperidone addition can be recommended on the basis of the criterion of two or more positive placebo-controlled trials. This systematized review supports the evidence that only a few AAs are effective in only a minority of the off-label conditions in which they are currently used and confirms that AAs are not all the same. Their use should be on the basis of a balance between efficacy and side effects, and the characteristics as well as the preference of the patient.
Dual-phase helical CT of pancreatic adenocarcinoma: assessment of resectability before surgery.

OBJECTIVE The aim of our study was to prospectively evaluate the accuracy of dual-phase helical CT in the preoperative assessment of resectability in patients with suspected pancreatic cancer using surgical and histopathologic correlation. SUBJECTS AND METHODS Between January 1999 and December 2000, 76 patients with suspected pancreatic cancer underwent preoperative evaluation and staging with dual-phase helical CT (3-mm collimation for pancreatic phase, 5-mm collimation for portal phase). Iodinated contrast material was injected IV (170 mL at a rate of 4 mL/sec); acquisition began at 40 sec during the pancreatic phase and at 70 sec during the portal phase. Three radiologists prospectively evaluated the imaging findings to determine the presence of pancreatic tumor and signs of unresectability (liver metastasis, vascular encasement, or regional lymph nodes metastasis). The degree of tumor-vessel contiguity was recorded for each patient (no contiguity with tumor, contiguity of < 50%, or contiguity of > or =50%). RESULTS Thirty-nine patients with pancreatic adenocarcinoma were surgically explored. Curative resections were attempted in 34 patients and were successful in 25. The positive predictive value for resectability was 73.5%. Nine patients considered resectable on the basis of CT findings were found to be unresectable at surgery because of liver metastasis (n = 5), vascular encasement (n = 2), or lymph node metastasis (n = 2). We found that the overall accuracy of helical CT as a tool for determining whether a pancreatic adenocarcinoma was resectable was 77% (30/39 patients). CONCLUSION Dual-phase helical CT is a useful technique for preoperative staging of pancreatic cancer. The main limitation of CT is that it may not reveal small hepatic metastases.
Physiological and molecular characterization of flor yeasts: Polymorphism of flor yeast populations

Yeast strains which form velum on the surface of Sherry wine during the aging process have been isolated and characterized. According to their metabolic and molecular features most of the yeasts that were isolated belong to different races of Saccharomyces cerevisiae (beticus, cheresiensis, montuliensis and rouxii). Due to the conditions under which these yeasts were isolated, all strains have in common the capacity to develop a film as an adaptive mechanism which allows them to grow and survive in 15·5% vol. ethanol. All strains were prototrophs for amino acids and most vitamins but they gave different responses to the killer factor. However, whereas their physiological features were similar, they showed a great heterogeneity with regards to the nuclear and mitochondrial genome (mtDNA): DNA content per cell was quite variable (1·3 to 2n), electrophoretic karyotypes of nuclear genomes indicated a main pattern with some variations, and polymorphism shown by the mtDNA was very high. Under extreme conditions such as Sherry wine with 15·5% vol. ethanol, no fermentable sugar and an exclusively oxidative metabolism, cells hardly grow and the maintenance of a live population depends on survival and respiration, which in turn depend on the mtDNA. At the same time these environmental conditions are mutagenic for the mtDNA, causing an increase in variation. Thus, the polymorphism observed might reflect the enormous variability induced by the ethanol followed by the selection of those mtDNA sequences which make the mitochondria metabolically active under these conditions.
Malaria control in East Africa: the Kampala Conference and the Pare-Taveta Scheme: a meeting of common and high ground.

The 1950 Malaria Conference in Equatorial Africa, held in Kampala, Uganda, has been remembered primarily for its decision to control malaria '. by modern methods as soon as feasible, whatever the original degree of endemicity, and without awaiting the outcome of further experiments. ' This decision was far from conclusive and, indeed, reflects only one side of the argument which brought two groups of malariologists into direct opposition on the wisdom of malaria control in equatorial Africa, using modern methods such as DDT. Through an examination of the unpublished verbatim transcript of the Kampala Conference, we are able to document the 'furious debates' which took place at Kampala in 1950. We highlight, in particular, the adamant concerns expressed by some of the delegates that intervention in areas of high malaria transmission might lead to a loss of naturally acquired immunity which, in turn, could give rise to a resurgence of malaria, should the control strategies fail to be sustained. As we show, this concern had been expressed by a number of malariologists working in East Africa in the first half of the twentieth century, but it was only with the advent of DDT, as a residual insecticide, that the implications of wide-spread control, in the absence of any knowledge of the long-term consequences, became a serious possibility. While the Kampala Conference gave the 'go ahead' to control malaria in Africa without awaiting the outcome of 'further experiments', a number of participants insisted that a field trial should be set up to evaluate the impact of malaria on areas of high transmission both before and after spraying: to this end, a field trial in Pare-Taveta was carried out in 1954-59. In this paper we look at the Kampala Conference for its scientific debates and the Pare-Taveta Scheme for its field applications. In the final part of the paper, we address a number of questions raised at Kampala which have, once more, become contentious issues, following the recent successful trials of ITBNs. We believe that an understanding of the historical foundations of these issues should provide an important component of the new WHO campaign to Roll Back Malaria.
Effects of cannabinoids on prefrontal neuronal responses to ventral tegmental area stimulation

Cannabinoids activate the firing of mesoprefrontocortical dopamine neurons and release dopamine in the prefrontal cortex. This study was undertaken with the aim of clarifying the interaction between cannabinoids and mesocortical system in the prefrontal cortex. The effect of Δ9‐tetrahydrocannabinol (Δ9‐THC) and the synthetic CB1 agonist WIN55,212–2 (WIN) was studied by extracellular single unit recordings, in chloral hydrate anaesthetised rats, on the spontaneous activity of pyramidal neurons and on the inhibition produced on these neurons by the electrical stimulation of the ventral tegmental area (VTA). Intravenously administered Δ9‐THC and WIN (1.0 and 0.5 mg/kg, respectively), increased the firing rate of pyramidal neurons projecting to the VTA. VTA stimulation produced a phasic inhibition (167 ± 6 ms) in 79% of prefrontal cortex pyramidal neurons. Δ9‐THC and WIN reverted this inhibition in 73% and 100% of the neurons tested, respectively. The subsequent administration of the selective CB1 antagonist SR141716A (1 mg/kg) readily suppressed the effects of both cannabinoids and restored the inhibitory response to VTA stimulation. Moreover, when administered alone, SR141716A prolonged the inhibition in 55.6% of the neurons tested. The results indicate that stimulation of CB1 receptors by cannabinoids results in an enhanced excitability of prefrontal cortex pyramidal neurons as indexed by the suppression of the inhibitory effect of VTA stimulation and by the increase in firing rate of antidromically identified neurons projecting to the VTA. Furthermore, our results support the view that endogenous cannabinoids exert a negative control on dopamine activity in the prefrontal cortex. This study may be relevant in helping to understand the influence of cannabinoids on cognitive processes mediated by the prefrontal cortex.
Update on the Japanese guidelines for the use of infliximab and etanercept in rheumatoid arthritis

Application of biological agents targeting tumor necrosis factor-α (TNF-α) caused a paradigm shift in the treatment of rheumatoid arthritis (RA). The introduction of infliximab in 2003 and etanercept in 2005 in Japan had a significant impact on both Japanese rheumatologists and RA patients, although serious adverse effects such as bacterial pneumonia, tuberculosis and Pneumocystis jiroveci pneumonia are significant concerns. Based on the data from post-marketing surveillance in Japan and accumulating evidence worldwide, the Internal Medicine Rheumatology Study Group of the Ministry of Health, Labor and Welfare (MHLW), Japan, has updated the guidelines for the use of anti-TNF-α agents for RA, which were subsequently approved by the Board of Japan College of Rheumatology (JCR). In the present revised guidelines, we combined the guidelines for use of each of infliximab and etanercept together with some modifications and precautions, paying special attention to serious adverse reactions. Although it is still controversial whether the use of TNF-α blocking agents per se increases the risk of infection or not, bacterial pneumonia, regardless of the pathogens, is the most frequent complications in RA. The risk factors associated with pneumonia identified in the post-marketing surveillance of infliximab in Japan are presented in this guideline. The diagnostic algorithm is also designed for early diagnosis and treatment of pulmonary lesions seen during the treatment of biological agents. Preventive measures and precautions against tuberculosis, another frequent and significant complication in Japan, are also described. Furthermore, risk factors for developing Pneumocystis pneumonia, which uniquely occurs at 30- to 50-fold frequency under TNF-α blockade therapy in Japan, are described here and its preventive measures are discussed. It is stressed that secondary-care rheumatologists should be better familiarized with the proper use of TNF-α blocking agents and be alert to any adverse events for a better management of RA patients.
Recognition of Orobanche cumana Below-Ground Parasitism Through Physiological and Hyper Spectral Measurements in Sunflower (Helianthus annuus L.)

Broomrape (Orobanche and Phelipanche spp.) parasitism is a severe problem in many crops worldwide, including in the Mediterranean basin. Most of the damage occurs during the sub-soil developmental stage of the parasite, by the time the parasite emerges from the ground, damage to the crop has already been done. One feasible method for sensing early, below-ground parasitism is through physiological measurements, which provide preliminary indications of slight changes in plant vitality and productivity. However, a complete physiological field survey is slow, costly and requires skilled manpower. In recent decades, visible to-shortwave infrared (VIS-SWIR) hyperspectral tools have exhibited great potential for faster, cheaper, simpler and non-destructive tracking of physiological changes. The advantage of VIS-SWIR is even greater when narrow-band signatures are analyzed with an advanced statistical technique, like a partial least squares regression (PLS-R). The technique can pinpoint the most physiologically sensitive wavebands across an entire spectrum, even in the presence of high levels of noise and collinearity. The current study evaluated a method for early detection of Orobanche cumana parasitism in sunflower that combines plant physiology, hyperspectral readings and PLS-R. Seeds of susceptible and resistant O. cumana sunflower varieties were planted in infested (15 mg kg-1 seeds) and non-infested soil. The plants were examined weekly to detect any physiological or structural changes; the examinations were accompanied by hyperspectral readings. During the early stage of the parasitism, significant differences between infected and non-infected sunflower plants were found in the reflectance of near and shortwave infrared areas. Physiological measurements revealed no differences between treatments until O. cumana inflorescences emerged. However, levels of several macro- and microelements tended to decrease during the early stage of O. cumana parasitism. Analysis of leaf cross-sections revealed differences in range and in mesophyll structure as a result of different levels of nutrients in sunflower plants, manifesting the presence of O. cumana infections. The findings of an advanced PLS-R analysis emphasized the correlation between specific reflectance changes in the SWIR range and levels of various nutrients in sunflower plants. This work demonstrates potential for the early detection of O. cumana parasitism on sunflower roots using hyperspectral tools.
Additive effect of three noradrenergic genes (ADRA2A, ADRA2C, DBH) on attention‐deficit hyperactivity disorder and learning disabilities in Tourette syndrome subjects

Halperin et al. (Halperin JM, Newcorn JH, Koda VH, Pick L, McKay KE, Knott P. Noradrenergic mechanisms in ADHD children with and without reading disabilities: a replication and extension. J Am Acad Child Adolesc Psychiatry 1997: 36: 1688–1696) reported a significant increase in plasma norepinephrine (NE) in attention‐deficit hyperactivity disorder (ADHD) children with reading and other cognitive disabilities compared to ADHD children without learning disabilities (LD). We examined the hypothesis that ADHD±LD was associated with NE dysfunction at a molecular genetic level by testing for associations and additive effects between polymorphisms at three noradrenergic genes – the adrenergic α2A receptor (ADRA2A), adrenergic α2C receptor (ADRA2C), and dopamine β‐hydroxylase (DBH) genes. A total of 336 subjects consisting of 274 individuals with Tourette syndrome (TS) and 62 normal controls were genotyped. Regression analysis showed a significant correlation between scores for ADHD, a history of LD, and poor grade‐school academic performance that was greatest for the additive effect of all three genes. Combined, these three genes accounted for 3.5% of the variance of the ADHD score (p=0.0005). There was a significant increase in the number of variant NE genes progressing from subjects without ADHD (A−) or learning disorders (LD−) to A+LD− to A−LD+ to A+LD+ (p=0.0017), but no comparable effect for dopamine genes. These data support an association between NE genes and ADHD, especially in ADHD+LD subjects.
Electrical characterization of through silicon vias (TSVs) with an on chip bus driver for 3D IC integration

In this study, an on chip bus driver TEG (test element group) has been developed for the data transmission performance at TSVs for 3D IC integration. The on chip bus driver TEG consists of transceiver (TX), receiver (RX) and TSV group which has 2, 4 and 8 TSVs for the analysis of the TSV transmission performance with different load effects which are caused by different number (2, 4, and 8) of chip stack (each chip is with one TSV). This chip has been made by TSMC's 0. 18μm process (FEOL) and ITRI's BEOL process. The square chip area is 1.69mm2 and power supply voltage is 1.8V with 30μm diameter TSVs on 30μm pitch and 100μm depth. Finally, a design guide line and a test tool will be proposed with the present on chip bus TEG.
The non-NMDA receptor antagonist NBQX does not affect rats performance in the object recognition task.

Though the AMPA receptor has been implicated in several neurodegenerative processes (epilepsy, ischemia, spasticity), its role in cognition is yet to be clarified. The aim of this study was to assess in the rat the effects of the AMPA receptor antagonist NBQX (3.5, 7, 10, 20 and 30 mgkg(-1), i.p.) on learning and memory. For this purpose, the object recognition task was chosen. NBQX, at the higher doses used (20 and 30 mgkg(-1)) caused respectively, depression of motility and ataxia, while given at lower doses (3.5, 7 and 10 mgkg(-1)) it did not influence animals performance in the object recognition paradigm. All rats acquired similarly well the task. In conclusion, these results would support and broaden previous observations on the lack of major involvement of AMPA receptors in the rat working memory mechanisms.
Nucleolar protein B23 has molecular chaperone activities

Protein B23 is an abundant, multifunctional nucleolar phosphoprotein whose activities are proposed to play a role in ribosome assembly. Szebeni et al. (1997) showed stimulation of nuclear import in vitro by protein B23 and suggested that this effect was due to a molecular chaperone‐like activity. Protein B23 was tested for chaperone activities using several protein substrates. The temperature‐dependent and ‐independent aggregation of the HIV‐1 Rev protein was measured using a zero angle light scattering (turbidity) assay. Protein B23 inhibited the aggregation of the Rev protein, with the amount of inhibition proportional to the concentration of B23 added. This activity was saturable with nearly complete inhibition when the molar ratio of B23:Rev was slightly above one. Protein B23 also protected liver alcohol dehydrogenase (LADH), carboxypeptidase A, citrate synthase, and rhodanese from aggregation during thermal denaturation and preserved the enzyme activity of LADH under these conditions. In addition, protein B23 was able to promote the restoration of activity of LADH previously denatured with guanidine‐HCl. Protein B23 preferentially bound denatured substrates and exposed hydrophobic regions when complexed with denatured proteins. Thus, by several criteria, protein B23 behaves like a molecular chaperone; these activities may be related to its role in ribosome biogenesis.
Overview on Regional Economic Development Gaps across the EU

Despite existing policies of regional development and cohesion at the national and the EU level, economic regional inequalities or disparities stay relatively high or decrease too slowly. In this context, policies to reduce economic regional disparities in the European Union are a constant concern both for policy-makers and for theoretical and empirical research because of the strong impact on sustainable development in general. In this study we combine elements of theoretical and policy discussions with the empirical assessment of economic regional development in the European Union in order to identify the state of regional disparities, what factors are favouring unbalanced growth in different regions of the EU and to find an appropriate theoretical setting to understand, explain and reduce with regional inequality in the EU
Molecular Genetics of Pediatric Brain Stem Gliomas. Application of PCR Techniques to Small and Archival Brain Tumor Specimens

Brain stem gliomas are pediatric astrocytomas that histologically resemble adult supratentorial astrocytomas such as glioblastomas multiforme (GBM). Our molecular genetic studies have suggested that adult GBM can be divided into two genetic subsets: tumors with p53 tumor suppressor gene mutations and chromosome 17p loss that occur more commonly in younger patients; and tumors with epidermal growth factor receptor (EGFR) gene amplification that occur more commonly in older patients. Brain stem gliomas have not been studied since biopsies of these tumors are rare and extremely small. We investigated the molecular genetic composition of seven brain stem glioblastomas (two small biopsies, five autopsies) using polymerase chain reaction (PCR) assays for chromosomal loss, gene mutation and gene amplification. Four cases lost portions of chromosome 17p that included the p53 gene. These four cases and one additional case had mutations in the p53 gene. None of the cases showed amplification of the EGFR gene. Allelic losses of the long arm of chromosome 10 were noted in four cases. These results suggest similarities between pediatric brain stem glioblastomas and those GBM that occur in younger adult patients, and confirm the utility of PCR-based means of studying small and archival brain tumor specimens.
Disease, Disorder, or Deception? Latah as Habit in a Malay Extended Family

Thirty-seven cases of latah are examined within the author's Malay extended family (TV=115). Based on ethnographic data collected and a literature review, cases are readily divisible into two broad categories: habitual (N=33) and performance (N=4). The first form represents an infrequent, culturally conditioned habit that is occasionally used as a learned coping strategy in the form of a cathartic stress response to sudden startle with limited secondary benefits (i.e., exhibiting brief verbal obscenity with impunity). In this sense, it is identical to Western swearing. Performers are engaged in conscious, ritualized social gain through the purported exploitation of a neurophysiological potential. The latter process is essentially irrelevant, akin to sneezing or yawning. It is concluded that latah is a social construction of Western-trained universalist scientists. The concept of malingering and fraud in anthropology is critically discussed
Time accelerated Monte Carlo simulations of biological networks using the binomial r-leap method

UNLABELLED Developing a quantitative understanding of intracellular networks requires simulations and computational analyses. However, traditional differential equation modeling tools are often inadequate due to the stochasticity of intracellular reaction networks that can potentially influence the phenotypic characteristics. Unfortunately, stochastic simulations are computationally too intense for most biological systems. Herein, we have utilized the recently developed binomial tau-leap method to carry out stochastic simulations of the epidermal growth factor receptor induced mitogen activated protein kinase cascade. Results indicate that the binomial tau-leap method is computationally 100-1000 times more efficient than the exact stochastic simulation algorithm of Gillespie. Furthermore, the binomial tau-leap method avoids negative populations and accurately captures the species populations along with their fluctuations despite the large difference in their size. AVAILABILITY http://www.dion. che.udel. edu/multiscale/Introduction.html. Fortran 90 code available for academic use by email. SUPPLEMENTARY INFORMATION Details about the binomial tau-leap algorithm, software and a manual are available at the above website.
