Abstract
Paradoxical reaction (PR) occurs when a drug elicits a reaction contrary to what was expected. To clarify the clinical features and genetic background of individuals susceptible to PR, we analyzed the clinical course of patients in whom psoriatic eruptions worsened or newly developed during tumor necrosis factor (TNF) antagonist administration and the role of focal infections and genetic variations. Of 125 patients who received TNF antagonist therapy for psoriasis, acrodermatitis continua of Hallopeau (ACH), generalized pustular psoriasis (GPP), or palmoplantar pustular psoriasis (PPP), eight patients with PR were surveyed at our hospital Dermatology Department between 2010 and 2021. A survey was also done on six patients who received TNF antagonist therapy for Crohn's disease, rheumatoid arthritis, ankylosing spondylitis, and hidradenitis suppurativa and were referred to our department due to PR. Additionally, Sanger sequencing analysis was performed for all exons and flanking introns of IL36RN (interleukin 36 receptor antagonist), CARD14 (caspase recruitment domain-containing protein 14), and AP1S3 (adaptor-related protein complex 1 subunit sigma 3). The clinical assessment of the 14 patients demonstrated an average age at PR onset of 48.4 years, a male : female ratio of 5:9, and a mean administration period until onset of 9.2 months. The clinical types of PR were plaque psoriasis, PPP, GPP, pustulosis, acne, ACH, hair loss, and exacerbation of arthralgia. Histopathology revealed psoriasiform dermatitis in three patients. One patient continued TNF antagonist therapy. All of the patients with psoriasis and GPP had dental infections, suggesting that focal infection may be a risk factor of the development of PR following TNF antagonist therapy. Gene analysis demonstrated CARD14 gene variants associated with RA, CD, AS, or PPP in four patients. In addition, all of the patients with ACH and PPP experienced PR, suggesting that these diseases may predispose patients to PR to TNF antagonist therapy.

Abstract
Abstract
Background
Unlike age, frailty is often not taken into account in treatment indications of Endovascular treatment (EVT). One of the reason is that there was little known the relationship between frailty and the outcome of EVT for super elderly patients with peripheral artery disease (PAD). We investigate impacts of frailty on the super elderly patient prognosis who underwent EVT.
Purpose
To investigate impacts of frailty on the super elderly patient prognosis who underwent EVT.
Methods
From August 2015 to July 2016, 335 consecutive patients who underwent EVT were enrolled in the I-PAD registry from 7 institutes in Nagano prefecture. Among them, we selected and analyzed 91 super elderly PAD patients (≥80 years-old) and divided them into two groups:those with moderate or higher frailty (Clinical Frailty Scale (CFS) ≥6, n=28) and those without (CFS ≤5, n=63). The primary endpoints were cardiovascular death and major adverse cardiovascular and limb events (MACLE), defined as a composite of cardiovascular death, myocardial infarction, stroke, admission for heart failure, major amputation and revascularization.
Results
The median follow-up period was 2.7 years. Freedom rate from cardiovascular death and MACLE were significantly lower among patients with moderate or higher frailty than among those without (47.0% vs. 58.0%, P=0.03; 39.1% vs. 68.5%, P<0.01).
Conclusion
The prognosis of super elderly patients with moderate or higher frailty is worse than those without.

Abstract
Changes in gene regulation underlie much of phenotypic evolution1. However, our understanding of the potential for regulatory evolution is biased, because most evidence comes from either natural variation or limited experimental perturbations2. Using an automated robotics pipeline, we surveyed an unbiased mutation library for a developmental enhancer in Drosophila melanogaster. We found that almost all mutations altered gene expression and that parameters of gene expression-levels, location, and state-were convolved. The widespread pleiotropic effects of most mutations may constrain the evolvability of developmental enhancers. Consistent with these observations, comparisons of diverse Drosophila larvae revealed apparent biases in the phenotypes influenced by the enhancer. Developmental enhancers may encode a higher density of regulatory information than has been appreciated previously, imposing constraints on regulatory evolution.

Abstract
BACKGROUND With the increasing use of biological agents for the treatment of psoriasis, the numbers of patients with interstitial lung disease (ILD) associated with biologics have also increased. Many of these cases were associated with tumour necrosis factor (TNF)-α inhibitors, but cases associated with other families of biologics have also been reported in Japan. AIM To analyse the background factors of patients who developed ILD, and to discuss better management of biological treatment. METHOD We reviewed 246 patients with psoriasis who were treated with biological agents in our department to identify any pulmonary adverse events (AEs). Data on patients who developed ILD were extracted to analyse background factors, clinical type of psoriasis, time to onset of ILD, pre-existing ILD, smoking habit and prescribed drugs. RESULTS Pulmonary AEs were seen in 22 cases, of which 11 were diagnosed as drug-induced ILD. The causative drugs were mainly TNF-α inhibitors, accounting for eight cases (six treated with infliximab, two with adalimumab). The remaining three cases were associated with secukinumab, ustekinumab and ixekizumab (n = 1 each). Notably, these three cases also had a history of drug-induced ILD. CONCLUSION Patients with a history of drug-induced ILD seem to be more susceptible to developing another ILD induced by biologics, even if treated with interleukin-17 inhibitors. Thorough screening of risk factors and evaluation for eligibility, and careful monitoring during treatment are the best solutions to avoid serious pulmonary AE. Early detection and precise diagnosis of pulmonary AEs, especially differentiation from infectious diseases, is essential for managing biological treatment.

Abstract
Eukaryotic transcription factors (TFs) form complexes with various partner proteins to recognize their genomic target sites. Yet, how the DNA sequence determines which TF complex forms at any given site is poorly understood. Here, we demonstrate that high-throughput in vitro DNA binding assays coupled with unbiased computational analysis provide unprecedented insight into how different DNA sequences select distinct compositions and configurations of homeodomain TF complexes. Using inferred knowledge about minor groove width readout, we design targeted protein mutations that destabilize homeodomain binding both in vitro and in vivo in a complex-specific manner. By performing parallel systematic evolution of ligands by exponential enrichment sequencing (SELEX-seq), chromatin immunoprecipitation sequencing (ChIP-seq), RNA sequencing (RNA-seq), and Hi-C assays, we not only classify the majority of in vivo binding events in terms of complex composition but also infer complex-specific functions by perturbing the gene regulatory network controlled by a single complex.

Abstract
[Purpose] The purpose of this study was to identify the factors influencing change in
life-space mobility after total knee arthroplasty (TKA) in patients with severe knee
osteoarthritis (knee OA). [Participants and Methods] Overall, 58 primary unilateral TKA
recipients (9 males and 49 females; age ± SD 74.6 ± 6.5 years) were enrolled. We evaluated
Life-Space Assessment (LSA) scores, knee extensor strength, Timed Up and Go test (TUG),
one-leg standing time (OLS), Western Ontario and McMaster Universities osteoarthritis
Index, and physical activity self-efficacy (SE) before surgery and at 3 months
post-operation. [Results] Life space mobility significantly expanded 3 months after
surgery compared with preoperative baseline. Preoperatively, walking SE and knee extensor
muscle strength on the operative side were found to have strong correlation with LSA
scores, while stairs SE and knee extensor muscle strength of the operative side were
correlated at 3 months post-operation. [Conclusion] These findings suggest that to expand
the life-space mobility of TKA recipients, it is important to enhance self-efficacy for
general physical activity in addition to strengthening the quadriceps muscles.

Abstract
OBJECTIVE The objective of this study was to clarify the efficacy and safety of factor Xa inhibitors for antiphospholipid syndrome patients in real world utilization. METHODS This is a retrospective cohort study comprised of all consecutive patients with antiphospholipid syndrome in our department over a period of 28 years. Patients treated with factor Xa inhibitors were extracted from the cohort. As a control group, patients treated with warfarin were selected from the same cohort with matched age, gender, coexistence of systemic lupus erythematosus, and the presence of antiplatelet therapy, after which we used a propensity score for each of the risk factors as an additional covariate in multivariate Cox proportional hazard regression. The primary endpoint was set as thrombotic and hemorrhagic event-free survival for five years. RESULTS Among 206 patients with antiphospholipid syndrome, 18 had a history of anti-Xa therapy (five rivaroxaban, 12 edoxaban, one apixaban). Fourteen out of 18 patients on anti-Xa therapy had switched to factor Xa inhibitors from warfarin. Event-free survival was significantly shorter during anti-Xa therapy than that during warfarin therapy (hazard ratio: 12.1, 95% confidence interval: 1.73-248, p = 0.01) ( Figure 1(a) ). Similarly, event-free survival in patients treated with factor Xa inhibitors was significantly shorter compared with controls (hazard ratio: 4.62, 95% confidence interval: 1.54-13.6, p = 0.0075). In the multivariate Cox proportional hazard model, event-free survival in patients with anti-Xa therapy remained significantly shorter (hazard ratio: 11.9, 95% confidence interval: 2.93-56.0, p = 0.0005). CONCLUSIONS Factor Xa inhibitors may not be recommended for antiphospholipid syndrome.

Abstract
We have discovered room-temperature low-field colossal magnetoresistance (CMR) in an A-site ordered NdBaMn_{2}O_{6} crystal. The resistance changes more than 2 orders of magnitude at a magnetic field lower than 2 T near 300 K. When the temperature and magnetic field sweep from an insulating (metallic) phase to a metallic (insulating) phase, the insulating (metallic) conduction changes to the metallic (insulating) conduction within 1 K and 0.5 T, respectively. The CMR is ascribed to the melting of the charge and orbital ordering. The entropy change which is estimated from the B-T phase diagram is smaller than what is expected for the charge and orbital ordering. The suppression of the entropy change is attributable to the loss of the short-range ferromagnetic fluctuation of Mn spin moments, which is an important key of the high temperature and low magnetic field CMR effect.

Abstract
In magnetoelectric materials, where the time-reversal and space-inversion symmetries are simultaneously broken, optical properties can differ between the opposite propagation directions of light. We report on an experimental observation of nonreciprocal trajectory of a light ray in magnetoelectric material CuB_{2}O_{4}. The light is refracted in different ways between the opposite propagation directions of light. We find a nonreciprocal refraction at the interface between a matter with macroscopic toroidal moment and vacuum. The resultant nonreciprocal deflection of the light is 0.005 deg, which is quantitatively explained using Fermat's principle.

Abstract
Pustulotic arthro-osteitis, occasionally complicated with palmoplantar pustulosis, affects patients' activities of daily living. Granulocyte and monocyte adsorption apheresis selectively removes activated granulocytes and monocytes by means of extracorporeal circulation. Although the efficacy of granulocyte and monocyte adsorption apheresis in the treatment of generalized pustular psoriasis has been proved, very few reports have assessed its efficacy in the treatment of palmoplantar pustulosis and pustulotic arthro-osteitis. Ten pustulotic arthro-osteitis patients with five palmoplantar skin manifestations were treated with weekly granulocyte and monocyte adsorption apheresis over 5 weeks. Skin manifestations were assessed using palmoplantar pustulosis area and severity index, and joint symptoms were assessed using a visual analog scale of joint pain, tender joint count, swollen joint count and C-reactive protein immediately before, after and at the 3-month follow up of the five granulocyte and monocyte adsorption apheresis sessions. Two out of five patients with skin manifestations achieved more than 50% improvement in their score (remarkably improved). However, in two patients, deterioration was noted, in one of whom the skin manifestations remained unchanged at the 3-month follow up. In five out of the 10 patients, the joint symptoms were assessed as better than improved at the 3-month follow up. No deterioration was noted at the 3-month follow up. In three patients, reduction or cessation of medication for arthralgia was possible. We concluded that granulocyte and monocyte adsorption apheresis is a therapeutic option to consider when pustulotic arthro-osteitis is recalcitrant to conventional therapy.

Abstract
Introduction Although thoracic endovascular aortic repair (TEVAR) has become a promising treatment for complicated acute type B dissection, its role in treating chronic post-dissection thoraco-abdominal aortic aneurysm (TAA) is still limited owing to persistent retrograde flow into the false lumen (FL) through abdominal or iliac re-entry tears. Report A case of chronic post-dissection TAA treatment, in which a dilated descending FL ruptured into the left thorax, is described. The primary entry tear was closed by emergency TEVAR and multiple abdominal re-entries were closed by EVAR. In addition, major re-entries at the detached right renal artery and iliac bifurcation were closed using covered stents. To close re-entries as far as possible, EVAR was carried out using the chimney technique, and additional aortic extenders were placed above the coeliac artery. A few re-entries remained, but complete FL thrombosis of the rupture site was achieved. Follow-up computed tomography showed significant shrinkage of the FL. Discussion In treating post-dissection TAA, entry closure by TEVAR is sometimes insufficient, owing to persistent retrograde flow into the FL from abdominal or iliac re-entries. Adjunctive techniques are needed to close these distal re-entries to obtain complete FL exclusion, especially in rupture cases. Recently, encouraging results of complete coverage of the thoraco-abdominal aorta with fenestrated or branched endografts have been reported; however, the widespread employment of such techniques appears to be limited owing to technical difficulties. The present method with multiple re-entry closures using off the shelf and immediately available devices is an alternative for the endovascular treatment of post-dissection TAA, especially in the emergency setting. A case of ruptured post-dissection thoraco-abdominal aneurysm was treated. Following entry closure by TEVAR, EVAR was performed to close multiple re-entries. Re-entries at the renal artery ostium and iliac artery were closed by covered stents. Complementary re-entry closure techniques are essential to treat false lumen rupture. This report demonstrates successful re-entry closure techniques following TEVAR.

Abstract
Abstract
Background:There are several small case series about the omental flap for breast reconstructions. However, the long-term oncological safety and the clinical benefits remain uncertain, especially the flap is used as a part of oncoplastic breast surgery. We retrospectively studied 200 patients who underwent oncoplastic breast surgery using the laparoscopically harvested omental flap.
Methods:A retrospective chart review of 200 patients who underwent oncoplastic surgery using the omental flap at our institution from April 2002 to March 2016 was performed. All the omental flaps were laparoscopically harvested, and mainly used as a partial reconstruction immediate after breast-conserving surgery (BCS). Short- and long-term laparoscopy-associated complications, local recurrences and cosmetic outcomes were evaluated.
Results:Although 46 cases of nipple-sparing mastectomy or skin-sparing mastectomy were included, most of patients underwent partial breast reconstruction after BCS. The successful rate of laparoscopically harvesting of the omental flap was 99.5% (199 out of 200). The rate of complications was 12.0%. Laparoscopy-associated complications occurred in 4 cases (2.0%). The rate of positive margin was 6.5%. Local recurrence occurred in two cases (1.0%) during medial follow-up period of 78 months. In 24 patients (12.0%), the volume of the flap was insufficient. When applied to nipple-sparing mastectomy or skin-sparing mastectomy, volume luck occurred in 32.6% of patients. Cosmetic outcome was mostly satisfactory. Approximately 80% of patients scored good or excellent evaluated with 4 point scale by 3 health professions. The size of the reconstructed breast basically did not change even after radiation therapy. Donor-site scars were almost negligible just like those of laparoscopic cholecystectomy.
Conclusions:The laparoscopically harvested omental flap has minimal donor-site morbidity and deformity. The long-term oncological safety is also promising. Although there is a limit of adaptable volume, the omental flap is an attractive option in partial breast reconstruction after BCS.

Abstract
We herein investigated, using a corticotropin-releasing factor (CRF) agonist and antagonists, whether CRF plays a role in the pathogenesis of ischemia/reperfusion-induced small intestinal lesions in rats. Under pentobarbital anesthesia, the superior mesenteric artery was clamped (ischemia) for 75 min, followed by reperfusion with removal of the clamp. After a 24-h reperfusion, the area of hemorrhagic lesions that developed in the small intestine was measured. Urocortin I (CRF receptor 1/2 agonist), astressin (CRF receptor 1/2 antagonist), NBI27914 (CRF receptor 1 antagonist), or astressin 2B (CRF receptor 2 antagonist) was administered i.v. twice: 5 min before ischemia and 6 hours after reperfusion. Ischemia/reperfusion caused hemorrhagic lesions in the small intestine in ampicillin- and aminoguanidine-inhibitable manners, accompanied by enterobacterial invasion and the up-regulation of inducible nitric oxide synthase expression and myeloperoxidase activity. The severity of ischemia/reperfusion-induced lesions was significantly reduced by astressin and astressin 2B, but not by NBI27914, with the suppression of bacterial invasion, myeloperoxidase activity, and inducible nitric oxide synthase expression. In contrast, urocortin I markedly aggravated these lesions, and this response was completely abrogated by the co-administration of astressin 2B, but not NBI27914. The gene expression of CRF, CRF receptor 1, and CRF receptor 2 was observed in the small intestine, and remained unchanged following ischemia/reperfusion. These results suggest that ischemia/reperfusion caused hemorrhagic lesions in the small intestine, the pathogenesis of which involved enterobacteria and inducible nitric oxide synthase/nitric oxide. These lesions were aggravated by urocortin I in an astressin 2B-inhibitable manner, but suppressed by astressin in a CRF receptor 2-dependent manner. Endogenous CRF may be involved in the pathogenesis of ischemia/reperfusion-induced enteritis, possibly via the activation of peripheral CRF receptor 2.

Abstract
The present study aimed at establishing a new cryopreservation method for mouse pancreatic islets by vitrification using hollow fibers as a container. A unique feature of the hollow fiber vitrification (HFV) method is that this method achieves stable vitrification using a minimum volume of cryoprotectant (CPA) solution, thereby ensuring high viability of the islets. The cytotoxicity, optimum composition, and concentration of the CPAs for vitrifying islets were examined. The viability, functional-integrity of vitrified islets were evaluated in comparison with those vitrified by conventional methods. Insulin secretion was measured in vitro by a static incubation assay and the metabolic functions was tested after transplantation into Streptozotocin-induced diabetic mice. The combination of 15% dimethyl sulfoxide+15% ethylene glycol resulted in the best CPA solution for the HFV of islets. HFV showed the highest viability in comparison to 2 vitrification methods, open pulled straws and vitrification with EDT324 solution. The vitrified islets stably expressed β-cells markers NeuroD, Pancreatic and duodenal homeobox-1, and MafA. Transplantation of the vitrified islets achieved euglycemia of the host diabetic mice and response to an intraperitoneal glucose tolerance test to a similar extent as non-vitrified transplanted islets. The HFV method allows for efficient long-term cryopreservation of islets.

Abstract
We experimentally demonstrate one-way transparency of light in multiferroic CuB(2)O(4). The material is rendered transparent for light propagating in one direction, while opaque for light propagating in the opposite direction. The novel transparency results from a destructive interference of the electric dipole and magnetic dipole transitions. The realization of the effect has been accomplished by the application of a high magnetic field and the proper selection of the propagation direction of light in agreement with our quantum mechanical formulation of nonreciprocal directional dichroism.

Abstract
Regarding appropriate timings of discontinuation and resumption of biologics for psoriasis patients before and after elective surgeries, an international consensus has yet to be reached. The Japanese Dermatological Association of Guideline and Safety Manual for the use of Biologic Agents in Psoriasis 2013 states that infliximab (IFX) and adalimumab (ADA) should be withheld at least 4 and 2 weeks, respectively, before surgery and can be restarted as neither postoperative infection nor delayed wound healing is recognized. We experienced three generalized pustular psoriasis (GPP) patients and one plaque-type psoriasis patient undergoing surgeries during tumor necrosis factor (TNF)-α blocker therapy. Three GPP cases experienced uneventful post-surgical course. One psoriasis vulgaris patient on IFX had a wound healing delay with deterioration of psoriatic plaques which was restored by restarting IFX. The timing of suspension and resumption of TNF-α blockers in all cases were determined following the Japanese guideline.

Abstract
Protein-DNA binding is mediated by the recognition of the chemical signatures of the DNA bases and the 3D shape of the DNA molecule. Because DNA shape is a consequence of sequence, it is difficult to dissociate these modes of recognition. Here, we tease them apart in the context of Hox-DNA binding by mutating residues that, in a co-crystal structure, only recognize DNA shape. Complexes made with these mutants lose the preference to bind sequences with specific DNA shape features. Introducing shape-recognizing residues from one Hox protein to another swapped binding specificities in vitro and gene regulation in vivo. Statistical machine learning revealed that the accuracy of binding specificity predictions improves by adding shape features to a model that only depends on sequence, and feature selection identified shape features important for recognition. Thus, shape readout is a direct and independent component of binding site selection by Hox proteins.

Abstract
In animals, Hox transcription factors define regional identity in distinct anatomical domains. How Hox genes encode this specificity is a paradox, because different Hox proteins bind with high affinity in vitro to similar DNA sequences. Here, we demonstrate that the Hox protein Ultrabithorax (Ubx) in complex with its cofactor Extradenticle (Exd) bound specifically to clusters of very low affinity sites in enhancers of the shavenbaby gene of Drosophila. These low affinity sites conferred specificity for Ubx binding in vivo, but multiple clustered sites were required for robust expression when embryos developed in variable environments. Although most individual Ubx binding sites are not evolutionarily conserved, the overall enhancer architecture-clusters of low affinity binding sites-is maintained and required for enhancer function. Natural selection therefore works at the level of the enhancer, requiring a particular density of low affinity Ubx sites to confer both specific and robust expression.

Abstract
Injured peripheral neurons successfully activate intrinsic signaling pathways to enable axon regeneration. We have previously shown that dorsal root ganglia (DRG) neurons activate the mammalian target of rapamycin (mTOR) pathway following injury and that this activity enhances their axon growth capacity. mTOR plays a critical role in protein synthesis, but the mTOR-dependent proteins enhancing the regenerative capacity of DRG neurons remain unknown. To identify proteins whose expression is regulated by injury in an mTOR-dependent manner, we analyzed the protein composition of DRGs from mice in which we genetically activated mTOR and from mice with or without a prior nerve injury. Quantitative label-free mass spectrometry analyses revealed that the injury effects were correlated with mTOR activation. We identified a member of the soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) family of proteins, syntaxin13, whose expression was increased by injury in an mTOR-dependent manner. Increased syntaxin13 levels in injured nerves resulted from local protein synthesis and not axonal transport. Finally, knockdown of syntaxin13 in cultured DRG neurons prevented axon growth and regeneration. Together, these data suggest that syntaxin13 translation is regulated by mTOR in injured neurons to promote axon regeneration.

Abstract
The mycotoxin sterigmatocystin (STC) is produced mainly by some Aspergillus and Penicillium fungi; it naturally contaminates cereals, peanuts, and products derived from these crops, and is both mutagenic and carcinogenic. As an intermediate of aflatoxin (AF) biosynthesis, its structure is similar to that of AF. Although immunoaffinity columns (IACs) are a popular approach to sample clean-up, no IAC is commercially available for STC, but a commercially available IAC for AF shows cross reactivity to STC. We here developed a new method for analyzing STC in grains using such an IAC and liquid chromatography mass spectrometry (LCMS), and validated this method using six different grains. The STC limit of detection (signal-to-noise ratio, S/N = 3) was 2.5 pg (1.0 μg/kg in the product), and the calibration curve was linear in the range of 7.5-375 pg (3.0-150 μg/kg in the product). The within-day recovery of STC from samples spiked with STC at 5.0 and 50 μg/kg was 83.2-102.5% and the RSDr (relative standard deviation of repeatability) of these samples was 1.9-6.5%; the RSDr of STC-pretreated grain samples was 3.1-14.0%. Average recovery of STC from samples spiked with STC in the range of 5.0-100 μg/kg STC was 83.2-102.5%, with an RSDr of 0.24-6.5%; the RSDr of STC-pretreated grain samples was 2.4-14.0%. In an intermediate precision study, the average STC recovery from STC-spiked samples by three analysts was 95.2-107.5%, with RSDRi (intermediate precision) of 4.0-7.1%; the RSDRi of the STC-pretreated samples was 4.8-10.4%. Thus, the proposed method was effective for STC analysis in grains, and holds potential for a novel application of a commercial IAC, intended for AFs, in STC analysis.

Abstract
Malignant peripheral nerve sheath tumors (MPNST) constitute a rare variety of soft tissue sarcomas thought to originate from Schwann cells or pluripotent cells of the neural crest. Malignant triton tumor (MTT), a very rare, highly aggressive soft tissue tumor, is a subgroup of MPNST and is comprised of malignant Schwann cells coexisting with malignant rhabdomyoblasts. We herein report the case of a 24-year-old man who presented a subcutaneous mass in his right thigh. The mass was removed surgically in its entirety and radiation therapy was applied locally to prevent tumor regrowth. Nonetheless, the patient died 10 months after surgery from metastases to the lung and brain. He presented neither cafe-au-lait spots nor cutaneous neurofibromas. The histopathology showed a transition from a neurofibroma to an MTT, making this the second report of an MTT arising from a neurofibroma without neurofibromatosis type 1, an autosomal dominant disorder with which 50–70% of tumors reported in previous studies were associated. A histopathological examination using immunostaining with desmin confirmed this diagnosis. MTT has a poorer prognosis than MPNST and should therefore be regarded as a distinct clinical entity.

Abstract
Transcription factors that drive neuron type-specific terminal differentiation programs in the developing nervous system are often expressed in several distinct neuronal cell types, but to what extent they have similar or distinct activities in individual neuronal cell types is generally not well explored. We investigate this problem using, as a starting point, the C. elegans LIM homeodomain transcription factor ttx-3, which acts as a terminal selector to drive the terminal differentiation program of the cholinergic AIY interneuron class. Using a panel of different terminal differentiation markers, including neurotransmitter synthesizing enzymes, neurotransmitter receptors and neuropeptides, we show that ttx-3 also controls the terminal differentiation program of two additional, distinct neuron types, namely the cholinergic AIA interneurons and the serotonergic NSM neurons. We show that the type of differentiation program that is controlled by ttx-3 in different neuron types is specified by a distinct set of collaborating transcription factors. One of the collaborating transcription factors is the POU homeobox gene unc-86, which collaborates with ttx-3 to determine the identity of the serotonergic NSM neurons. unc-86 in turn operates independently of ttx-3 in the anterior ganglion where it collaborates with the ARID-type transcription factor cfi-1 to determine the cholinergic identity of the IL2 sensory and URA motor neurons. In conclusion, transcription factors operate as terminal selectors in distinct combinations in different neuron types, defining neuron type-specific identity features.

Abstract
The magnetization process of the orthogonal-dimer antiferromagnet SrCu2(BO3)2 is investigated in high magnetic fields of up to 118 T. A 1/2 plateau is clearly observed in the field range 84 to 108 T in addition to 1/8, 1/4, and 1/3 plateaus at lower fields. Using a combination of state-of-the-art numerical simulations, the main features of the high-field magnetization, a 1/2 plateau of width 24 T, a 1/3 plateau of width 34 T, and no 2/5 plateau, are shown to agree quantitatively with the Shastry-Sutherland model if the ratio of inter- to intradimer exchange interactions J'/J=0.63. It is further predicted that the intermediate phase between the 1/3 and 1/2 plateaus is not uniform but consists of a 1/3 supersolid followed by a 2/5 supersolid and possibly a domain-wall phase, with a reentrance into the 1/3 supersolid above the 1/2 plateau.

Abstract
Terminal differentiation programs in the nervous system are encoded by cis-regulatory elements that control the expression of terminal features of individual neuron types. We decoded the regulatory information that controls the expression of five enzymes and transporters that define the terminal identity of all eight dopaminergic neurons in the nervous system of the Caenorhabditis elegans hermaphrodite. We show that the tightly coordinated, robust expression of these dopaminergic enzymes and transporters ("dopamine pathway") is ensured through a combinatorial cis-regulatory signature that is shared by all dopamine pathway genes. This signature is composed of an Ets domain-binding site, recognized by the previously described AST-1 Ets domain factor, and two distinct types of homeodomain-binding sites that act in a partially redundant manner. Through genetic screens, we identified the sole C. elegans Distalless/Dlx ortholog, ceh-43, as a factor that acts through one of the homeodomain sites to control both induction and maintenance of terminal dopaminergic fate. The second type of homeodomain site is a Pbx-type site, which is recognized in a partially redundant and neuron subtype-specific manner by two Pbx factors, ceh-20 and ceh-40, revealing novel roles of Pbx factors in the context of terminal neuron differentiation. Taken together, we revealed a specific regulatory signature and cognate, terminal selector-type transcription factors that define the entire dopaminergic nervous system of an animal. Dopaminergic neurons in the mouse olfactory bulb express a similar combinatorial transcription factor collective of Ets/Dlx/Pbx factors, suggesting deep phylogenetic conservation of dopaminergic regulatory programs.

Abstract
We investigated the crystal structures of an ordered perovskite-type cobaltate, GdBaCo2O(5+δ) (δ < 0.5), at elevated temperatures by transmission electron microscopy. Above the magnetic ordering temperature, we observed a first-order structural phase transition between the low-temperature tetragonal 3a(p) × 3a(p) and high-temperature orthorhombic 1a(p) × 2a(p) superstructure phases (where a(p) is the perovskite-unit cell). Upon the application of a magnetic field, an incommensurate phase emerges around the structural phase-transition temperature, which indicates a magnetic-field-induced structural phase transition via no magnetic ordering in the ordered perovskite-type cobaltate.

Abstract
The prognostic significance of pack-years smoked (PY) and family history of cancer (FH) was studied using the Cox proportional hazard model in 970 patients with non-small cell lung cancer. PY influenced survival only in women after other variables were adjusted [Hazard ratio (HR): 1.75 (1.45-2.11)]. FH also influenced survival with marginal significance in women with stage I disease [HR: 2.17 (0.89-5.29), p=0.088]. Furthermore, these two factors operated additively in women [HR for patients with both smoking and family histories over those without either: 2.25 (1.18-4.26)], but not in men.

Abstract
A flock of commercial layer chicks in Hokkaido, Japan experienced mortality of 3.53% over the first 7 days of life. Affected chicks were depressed, anorexic and had diarrhoea. The striking pathological feature was dense colonization of epithelial surface of the duodenum by Enterococcus hirae. There was no obvious damage to the enterocytes associated with bacterial adherence. Enterococcus hirae organisms were isolated in large numbers from the small intestines, together with Escherichia coli.

Abstract
Carcinogenesis and cancer progression, driven by mutations in oncogenes and tumor-suppressor genes, result in biological differences between normal and cancer cells in various cellular processes. Specific genes and signaling molecules involved in such cellular processes may be potential therapeutic targets of agents that specifically interact with the key factors in cancer cells. Increased glucose uptake is fundamental to many solid tumors and well associated with increases in glycolysis and the overexpression of glucose transporters (GLUTs) such as GLUT1 and GLUT3 at the plasma membrane. Here, we used cell-based screening to identify glycogen synthase kinase-3β (GSK-3β) inhibitors that selectively target GLUT3-expressing tumorigenic HeLa cell hybrids as compared with non-tumorigenic hybrids that express GLUT1 alone. The GSK-3 inhibitors as well as GSK-3β RNAi suppressed GLUT3 expression at the level of transcription, leading to apoptosis. This suppression was associated with NF-κB in a p53-independent manner. Furthermore, GSK-3 inhibitors exhibited a synergistic effect with anticancer agents such as adriamycin and camptothecin in GULT3-overexpressing colon cancer cells, but little effect in non-producing A431 cells. These results suggest a potential use of GSK-3 inhibitors to selectively kill cancer cells that overexpress GLUT3.
