Ultrastructural Analysis of In Vivo Hypoglycemiant Effect of Two Polyoxometalates in Rats with Streptozotocin-Induced Diabetes
Authors: Bâlici Ştefana , Wankeu-Nya Modeste , Rusu Dan , Nicula Gheorghe Z. , Rusu Mariana , Florea Adrian , Matei Horea
Published: September 2015

Two polyoxometalates (POMs), synthesized through a self-assembling method, were used in the treatment of streptozotocin (STZ)-induced diabetic rats. One of these nanocompounds [tris(vanadyl)-substituted tungsto-antimonate(III)-anions—POM1] was previously described in the literature, whereas the second [tris-butyltin-21-tungsto-9-antimonate(III)-anions—POM2], was prepared by us based on our original formula. In rats with STZ-induced diabetes treated with POMs (up to a cumulative dose of 4 mg/kg bodyweight at the end of the treatments), statistically significant reduced levels of blood glucose were measured after 3 weeks, as compared with the diabetic control groups (DCGs). Ultrastructural analysis of pancreatic β-cells (including the mean diameter of secretory vesicles and of their insulin granules) in the treated diabetic rats proved the POMs contribute to limitation of cellular degeneration triggered by STZ, as well as to the presence of increased amounts of insulin-containing vesicles as compared with the DCG. The two POMs also showed hepatoprotective properties when ultrastructural aspects of hepatocytes in the experimental groups of rats were studied. Based on our in vivo studies, we concluded that the two POMs tested achieved hypoglycemiant effects by preventing STZ-triggered apoptosis of pancreatic β-cells and stimulation of insulin synthesis.
Perverse Politics: The Persistence of Mass Imprisonment in the Twenty-first Century
Authors: Thorpe Rebecca U.
Published: September 2015

I examine the political consequences of prison development in the United States. I theorize that the prison apparatus not only upholds a system of racial hierarchy and class stratification, but also links the economic stability of lower-class, rural whites to the continued penal confinement of poor, urban minorities. Analysis of an original dataset suggests that local reliance on existing prison infrastructure throughout many economically-depressed rural communities strengthens political support for harsh criminal punishments and militates against reform efforts. Political representatives have powerful interests in protecting rural prison investments, regardless of their actual economic impact in host communities. The evidence indicates that rural prison development contributes to the perceived economic viability and political power of rural areas, while reinforcing forms of punishment that destabilize poor urban neighborhoods and harm politically marginalized populations.
Taxing the Poor: Incarceration, Poverty Governance, and the Seizure of Family Resources
Authors: Katzenstein Mary Fainsod , Waller Maureen R.
Published: September 2015

In the last decades, the American state has radically enlarged the array of policy instruments utilized in today’s governance of the poor. Most recently, through a process of outright “seizure,” the state now exacts revenue from low-income families, partners, and friends of those individuals who in very large numbers cycle in and out of the nation’s courts, jails, and prisons. In an analysis of legislation, judicial cases, policy regulations, blog, chat-line postings, and survey data, we explore this new form of taxation. In doing so, we endeavor to meet two objectives: The first is to document policies which pressure individuals (mostly men) entangled in the court and prison systems to rely on family members and others (mostly women) who serve as the safety net of last resort. Our second objective is to give voice to an argument not yet well explored in the sizeable incarceration literature: that the government is seizing resources from low-income families to help finance the state’s own coffers, including the institutions of the carceral state itself. Until now, no form of poverty governance has been depicted as so baldly drawing on family financial support under the pressure of punishment to extract cash resources from the poor. This practice of seizure constitutes the very inversion of welfare for the poor. Instead of serving as a source of support and protection for poor families, the state saps resources from indigent families of loved ones in the criminal justice system in order to fund the state’s project of poverty governance.
A discussion of Alexander S. Kirschner's A Theory
of Militant Democracy: The Ethics of Combatting Political Extremism
Authors: Pappas Takis S.
Published: September 2015

The legitimacy claims of liberal democratic states are typically couched in the
language of individual rights and the rule of law. But contemporary liberal
democratic states increasingly appeal to a logic of security, law and order, and
the need to combat “political extremism.” This logic plays
out in Ukraine, Egypt, and Turkey, and in Greece and Germany, but also in the
U.S., France, and the UK. It is an increasingly important feature of politics in
societies that may be experiencing a rough “transition to
democracy,” but also in societies that are conventionally regarded as
“consolidated democracies.” The normative and practical
challenges presented by this situation are fundamental. Alexander S.
Kirschner’s A Theory of Militant Democracy: The Ethics of Combatting
Political Extremism offers one interesting take on these issues, which cut to
the core of political science as a discipline. We have thus invited a range of
political scientists from a variety of subfield and methodological perspectives
to comment on the book and on the broader topic the book engages—the
ethics of combatting political extremism and indeed the very political
construction of “political extremism.” -- Jeffrey C.

Forkhead box K2 modulates epirubicin and paclitaxel sensitivity through FOXO3a in breast cancer

Published: September 2015

The forkhead transcription factor FOXK2 has recently been implicated in cancer cell proliferation and survival, but a role in cancer chemotherapeutic drug resistance has hitherto not been explored. Here we demonstrate that FOXK2 has a central role in mediating the cytotoxic drug response in breast cancer. Clonogenic and cell viability assays showed that enhanced FOXK2 expression sensitizes MCF-7 breast cancer cells to paclitaxel or epirubicin treatment, whereas FOXK2 depletion by small interfering RNAs (siRNAs) confers drug resistance. Our data also showed that the activation of the tumour suppressor FOXO3a by paclitaxel and epirubicin is mediated through the induction of FOXK2, as depletion of FOXK2 by siRNA limits the induction of FOXO3a by these drugs in MCF-7 cells. Chromatin immunoprecipitation (ChIP) analysis showed that in response to drug treatment, FOXK2 accumulates and binds to the proximal FOXO3a promoter region in MCF-7 cells. Furthermore, we also uncovered that FOXK2 is deregulated and, therefore, can express at high levels in the nucleus of both the paclitaxel and epirubicin drug-resistant MCF-7 cells. Our results showed that ectopically overexpressed FOXK2 accumulates in the nuclei of drug-resistant MCF-7 cells but failed to be recruited to target genes, including FOXO3a. Crucially, we found that FOXO3a is required for the anti-proliferative and epirubicin-induced cytotoxic function of FOXK2 in MCF-7 cells by sulphorhodamine and clonogenic assays. The physiological importance of the regulation of FOXO3a by FOXK2 is further confirmed by the significant correlations between FOXO3a and FOXK2 expression in breast carcinoma patient samples. Further survival analysis also reveals that high nuclear FOXK2 expression significantly associates with poorer clinical outcome, particularly in patients who have received conventional chemotherapy, consistent with our finding that FOXK2 is deregulated in drug-resistant cells. In summary, our results suggest that paclitaxel and epirubicin target the FOXK2 to modulate their cytotoxicity and deregulated FOXK2 confers drug resistance.
Unveiling the metabolic potential of two soil-derived microbial consortia selected on wheat straw
Authors: Jiménez Diego Javier , Chaves-Moreno Diego , van Elsas Jan Dirk
Published: September 2015

Based on the premise that plant biomass can be efficiently degraded by mixed microbial cultures and/or enzymes, we here applied a targeted metagenomics-based approach to explore the metabolic potential of two forest soil-derived lignocellulolytic microbial consortia, denoted RWS and TWS (bred on wheat straw). Using the metagenomes of three selected batches of two experimental systems, about 1.2 Gb of sequence was generated. Comparative analyses revealed an overrepresentation of predicted carbohydrate transporters (ABC, TonB and phosphotransferases), two-component sensing systems and β-glucosidases/galactosidases in the two consortia as compared to the forest soil inoculum. Additionally, “profiling” of carbohydrate-active enzymes showed significant enrichments of several genes encoding glycosyl hydrolases of families GH2, GH43, GH92 and GH95. Sequence analyses revealed these to be most strongly affiliated to genes present on the genomes ofSphingobacterium,Bacteroides,FlavobacteriumandPedobacter spp. Assembly of the RWS and TWS metagenomes generated 16,536 and 15,902 contigs of ≥10 Kb, respectively. Thirteen contigs, containing 39 glycosyl hydrolase genes, constitute novel (hemi)cellulose utilization loci with affiliation to sequences primarily found in the Bacteroidetes. Overall, this study provides deep insight in the plant polysaccharide degrading capabilities of microbial consortia bred from forest soil, highlighting their biotechnological potential.
LAPTM4B is associated with poor prognosis in NSCLC and promotes the NRF2-mediated stress response pathway in lung cancer cells
Authors: Maki Yuho , Fujimoto Junya , Lang Wenhua , Xu Li , Behrens Carmen , Wistuba Ignacio I. , Kadara Humam
Published: September 2015

We recently demonstrated that lysosomal protein transmembrane 4 beta (LAPTM4B) is elevated in non-small cell lung cancers (NSCLCs) and in the surrounding premalignant airway field of cancerization. In the present study, we sought to begin to understand the relevance of LAPTM4B expression and signaling to NSCLC pathogenesis. In situ hybridization analysis of LAPTM4B transcript in tissue microarrays comprised of 368 NSCLCs demonstrated that LAPTM4B expression was significantly increased in smoker compared to non-smoker lung adenocarcinoma tumors (P < 0.001) and was significantly associated with poor overall survival (P < 0.05) in adenocarcinoma patients. Knockdown of LAPTM4B expression inhibited cell growth, induced cellular apoptosis and decreased cellular autophagy in serum starved lung cancer cells. Expression profiling coupled with pathways analysis revealed decreased activation of the nuclear factor erythroid 2-like 2 (NRF2) stress response pathway following LAPTM4B knockdown. Further analysis demonstrated that LAPTM4B augmented the expression and nuclear translocation of the NRF2 transcription factor following serum deprivation as well as increased the expression of NRF2 target genes such as heme oxygenase 1/HMOX1). Our study points to the relevance of LAPTM4B expression to NSCLC pathogenesis as well as to the probable role of LAPTM4B/NRF2 signaling in promoting lung cancer cell survival.

Immune activation and chronic inflammation are hallmark features of HIV infection causing T-cell depletion and cellular immune dysfunction in AIDS. Here, we addressed the issue whether HIV-1 Tat could affect T cell development and acute inflammatory response by generating a transgenic mouse expressing Tat in lymphoid tissue. Tat-Tg mice showed thymus atrophy and the maturation block from DN4 to DP thymic subpopulations, resulting in CD4+ and CD8+ T cells depletion in peripheral blood. In Tat-positive thymus, we observed the increased p65/NF-κB activity and deregulated expression of cytokines/chemokines and microRNA-181a-1, which are involved in T-lymphopoiesis. Upon LPS intraperitoneal injection, Tat-Tg mice developed an abnormal acute inflammatory response, which was characterized by enhanced lethality and production of inflammatory cytokines. Based on these findings, Tat-Tg mouse could represent an animal model for testing adjunctive therapies of HIV-1-associated inflammation and immune deregulation.

60 GHz broadband variable gain mixer using positive feedback in 65 nm CMOS
Authors: Wang Chong , Li Zhiqun , Li Qin , Wang Zhigong
Published: September 2015

A 60 GHz down‐conversion mixer for a superheterodyne receiver with an IF frequency of about 12 GHz is reported. On the basis of the double‐balanced Gilbert cell, the mixer comprises two series LCR networks to enlarge the IF bandwidth (BW) and a cross‐coupled pair used as positive feedback to the raise conversion gain (CG) at the load stage. By adjusting the bias of the cross‐coupled pair, the mixer features a variable CG. The mixer core only consumes 2.8 mA from a 1.2 V supply when the cross‐coupled pair is turned off, whereas the corresponding a 3 dB IF BW is from 6.5 to 17.5 GHz with a 3 dB CG, which is believed to be the widest IF BW ever reported for a 60 GHz down‐conversion mixer with an IF frequency of about 12 GHz. The CG can be enhanced by driving the cross‐coupled pair, which consumes another 2.4 mA, i.e. 5.2 mA in all for the mixer core. The CG will reach 7.5 dB and the corresponding 3 dB IF BW is from 8 to 16 GHz, where the CG and BW product against power consumption is also believed one of the best results ever reported for a 60 GHz down‐conversion mixer with IF frequency of about 12 GHz.
Effective capacity of communication systems over κ–μ shadowed fading channels
Authors: Zhang Jiayi , Dai Linglong , Gerstacker Wolfgang H. , Wang Zhaocheng
Published: September 2015

The effective capacity of communication systems over generalised κ–μ shadowed fading channels is investigated. A novel and analytical expression for the exact effective capacity is derived in terms of the extended generalised bivariate Meijer's‐G function. To intuitively reveal the impact of the system and channel parameters on the effective capacity, closed‐form expressions are derived for the effective capacity in the asymptotically high signal‐to‐noise ratio regime. The results demonstrate that the effective capacity is a monotonically increasing function of channel fading parameters κ and μ as well as the shadowing parameter m, while it decays to zero when the delay constraint θ → ∞.
Target tracking using Doppler‐only measurements in FM broadcast band commensal radar
Authors: Maasdorp F.D.V. , Inggs M.R. , Nadjiasngar R.
Published: September 2015

Radar research using transmitters of opportunity (commensal radar (CR)) has experienced a resurgence in popularity. Most published results to date used a multiple transmitter, single receiver site configuration with combinations of bearing, range and Doppler for target localisation. Doppler‐only tracking has received the least attention. This reported work demonstrates with field measurements, using a single frequency modulation broadcast radio transmitter and multiple, spatially distributed, low‐cost CR receivers, that Doppler‐only tracking is achievable with target position accuracies of 150 m, despite a course range resolution.
