Search for Antideuterons of Cosmic Origin Using the BESS-Polar II Magnetic-Rigidity Spectrometer.

We searched for antideuterons (d[over ¯]'s) in the 4.7×10^{9} cosmic-ray events observed during the BESS-Polar II flight at solar minimum in 2007-2008 but found no candidates. The resulting 95% C.L. upper limit on the d[over ¯] flux is 6.7×10^{-5} (m^{2} s sr GeV/n)^{-1} in an energy range from 0.163 to 1.100 GeV/n. The result has improved by more than a factor of 14 from the upper limit of BESS97, which had a potential comparable to that of BESS-Polar II in the search for cosmic-origin d[over ¯]'s and was conducted during the former solar minimum. The upper limit of d[over ¯] flux from BESS-Polar II is the first result achieving the sensitivity to constrain the latest theoretical predictions.

Internal Delensing of Cosmic Microwave Background Polarization B-Modes with the POLARBEAR Experiment.

Using only cosmic microwave background polarization data from the polarbear experiment, we measure B-mode polarization delensing on subdegree scales at more than 5σ significance. We achieve a 14% B-mode power variance reduction, the highest to date for internal delensing, and improve this result to 22% by applying for the first time an iterative maximum a posteriori delensing method. Our analysis demonstrates the capability of internal delensing as a means of improving constraints on inflationary models, paving the way for the optimal analysis of next-generation primordial B-mode experiments.

Rebound-associated vertebral fractures after discontinuation of denosumab for the treatment of maxillitis.

We reported a 69-year-old female who discontinued denosumab due to dental treatment and subsequently suffered rebound-associated vertebral fractures 10 months after the last injection. This case raised an alarm regarding the discontinuation of denosumab for dental treatment. Denosumab, a human monoclonal antibody administered by subcutaneous injection, to the best of our knowledge, is the only fully investigated inhibitor of receptor activator of nuclear factor kappa B ligand. Discontinuation of denosumab leads to bone turnover rebound and rapid bone mineral density loss. Several studies have reported rebound-associated vertebral fractures after discontinuation of denosumab. We report on a new case of rebound-associated vertebral fractures after discontinuation of denosumab. A 69-year-old female, who withdrew from denosumab treatment after 3 years due to maxillitis, presented to our hospital with severe low back pain without any history of trauma. Ten months had passed since the last injection. Magnetic resonance imaging showed five acute vertebral fractures, which appeared to be rebound-associated vertebral fractures caused by discontinuation of denosumab due to dental treatment. This case clearly demonstrates the risk of discontinuation of denosumab for dental treatment.

Differential visual ornamentation between brood parasitic and parental cuckoos.

The evolution of brood parasitism should affect adult phenotypic traits due to sexual selection as well as the parasite-host interactions, although it is rarely focused on. Sexual selection theory predicts extravagant secondary sexual characteristics in brood parasites whereas immature-like modest sexual characteristics in parental species. This is because juvenile-like immature traits can attract mates by exploiting parental care for young (i.e. attraction to young), and because the good parent process, which favours traits that signal parental care ability, would constrain the evolution of costly secondary sexual characteristics due to evolutionary trade-offs between parental investment and sexually selected traits. Using a phylogenetic comparative approach, we studied plumage and bare-part characteristics of adults in relation to brood parasitism in cuckoos (family Cuculidae), in which brood parasitism together with loss of parental care has evolved three times. As predicted, we found that nonparasitic cuckoos had plumage more similar to the juveniles than did brood parasitic cuckoos. Furthermore, nonparasitic cuckoos had a higher probability of having additional bare skin, that is a seemingly less costly, hatchling-like trait, than did brood parasitic cuckoos. This finding further supports the link between parental care and sexual selection, although the influence of a parasite-host interaction cannot be excluded. The analysis of evolutionary pathways suggested interdependent evolution of additional bare skin and brood parasitism. Brood parasitism together with the loss of parental care may prevent the maintenance of a modest phenotype similar to the young, and vice versa in some cases.

Antimelanoma differentiation-associated protein 5 antibody level is a novel tool for monitoring disease activity in rapidly progressive interstitial lung disease with dermatomyositis.

BACKGROUND: Antimelanoma differentiation-associated protein (anti-MDA)5 antibodies are associated with rapidly progressive interstitial lung disease (RP-ILD) in patients with clinically amyopathic dermatomyositis (CADM) or dermatomyositis (DM). OBJECTIVES: We aimed to evaluate the relevance of monitoring anti-MDA5 antibody levels for the management of RP-ILD in patients with CADM or DM. METHODS: Twelve patients with CADM (n = 10) or DM (n = 2) accompanied by RP-ILD were included. Baseline characteristics and outcomes were recorded. Serial measurements of anti-MDA5 antibody levels were measured. All patients were treated with corticosteroids, tacrolimus and intravenous cyclophosphamide. RESULTS: All patients achieved RP-ILD remission after combined immunosuppressive therapy for a mean of 6·8 months, with significant decreases noted in the mean anti-MDA5 antibody levels at remission. Six (50%) patients became anti-MDA5 antibody negative after therapy. After a mean follow-up of 31 months, RP-ILD relapse was observed in four (33%) patients in both the anti-MDA5 antibody sustained positive group and the negative conversion group. However, relapsed patients in the sustained positive group relapsed earlier than those in the negative conversion group. Thus, a decrease in anti-MDA5 antibody levels during remission was associated with longer remission. Relapses were associated with a reincrease of anti-MDA5 antibody levels in four of four (100%) patients. In contrast, none of the patients without reincrease in anti-MDA5 antibody exhibited symptoms of relapse during follow-up. Therefore, reincrease in anti-MDA5 antibody levels was associated with relapse. CONCLUSIONS: The anti-MDA5 antibody level is a novel parameter for monitoring and a good predictor of RP-ILD relapse in patients with CADM or DM.

Gate-Tunable Atomically Thin Lateral MoS2 Schottky Junction Patterned by Electron Beam.

Among atomically thin two-dimensional (2D) materials, molybdenum disulfide (MoS2) is attracting considerable attention because of its direct bandgap in the 2H-semiconducting phase. On the other hand, a 1T-metallic phase has been revealed, bringing complementary application. Recently, thanks to top-down fabrication using electron beam (EB) irradiation techniques, in-plane 1T-metal/2H-semiconductor lateral (Schottky) MoS2 junctions were demonstrated, opening a path toward the co-integration of active and passive two-dimensional devices. Here, we report the first transport measurements evidencing the formation of a MoS2 Schottky barrier (SB) junction with barrier height of 0.13-0.18 eV created at the interface between EB-irradiated (1T)/nonirradiated (2H) regions. Our experimental findings, supported by state-of-the-art simulation, reveal unique device fingerprint of SB-based field-effect transistors made from atom-thin 1T layers.

Hyaluronic acid pretreatment for Sendai virus-mediated cochlear gene transfer.

Gene therapy with viral vectors is one of the most promising strategies for sensorineural hearing loss. However, safe and effective administration of the viral vector into cochlear tissue is difficult because of the anatomical isolation of the cochlea. We investigated the efficiency and safety of round window membrane (RWM) application of Sendai virus, one of the most promising non-genotoxic vectors, after pretreatment with hyaluronic acid (HA) on the RWM to promote efficient viral translocation into the cochlea. Sendai virus expressing the green fluorescent protein reporter gene was detected throughout cochlear tissues following application combined with HA pretreatment. Quantitative analysis revealed that maximum expression was reached 3 days after treatment. The efficiency of transgene expression was several 100-fold greater with HA pretreatment than that without. Furthermore, unlike the conventional intracochlear delivery methods, this approach did not cause hearing loss. These findings reveal the potential utility of gene therapy with Sendai virus and HA for treatment of sensorineural hearing loss.

Neurodegeneration in frontotemporal lobar degeneration and motor neurone disease associated with expansions in C9orf72 is linked to TDP-43 pathology and not associated with aggregated forms of dipeptide repeat proteins.

AIMS: A hexanucleotide expansion in C9orf72 is the major genetic cause of inherited behavioural variant Frontotemporal dementia (bvFTD) and motor neurone disease (MND), although the pathological mechanism(s) underlying disease remains uncertain. METHODS: Using antibodies to poly-GA, poly-GP, poly-GR, poly-AP and poly-PR proteins, we examined sections of cerebral cortex, hippocampus, thalamus, cerebellum and spinal cord, from 20 patients with bvFTD and/or MND bearing an expansion in C9orf72 for aggregated deposits of dipeptide repeat proteins (DPR). RESULTS: Antibodies to poly-GA, poly-GP and poly-GR detected numerous rounded cytoplasmic inclusions (NCI) within granule cells of hippocampal dentate gyrus and those of the cerebellum, as well as 'star-burst' shaped NCI in pyramidal neurones of CA3/4 region of hippocampus. NCI were uncommon in Purkinje cells, and only very rarely seen in anterior horn cells. Poly-PA antibody detected occasional NCI within CA3/4 neurones alone, whereas poly-PR antibody did not identify any NCI but immunostained the nucleus of anterior horn cells, CA3/4 neurones and Purkinje cells, in patients with or without expansion in C9orf72, as well as in normal controls. Poly-GA antibody generally detected more DPR than poly-GP, which in turn was greater than poly-GR. All patients with bvFTD + MND or MND showed plentiful p62/TDP-43 positive inclusions in remaining anterior horn cells. CONCLUSION: Degeneration and loss of anterior horn cells associated with expansions in C9orf72 occurs in the absence of DPR, and implies that changes involving loss of nuclear staining for and a cytoplasmic aggregation of TDP-43 are more likely to be the cause of this.

A retrospective analysis of nonresponse to daily teriparatide treatment.

UNLABELLED: Some patients with osteoporosis do not respond to teriparatide treatment. Prior bisphosphonate use, lower bone turnover marker (BTMs) concentrations, and lower early increases in BTMs were significantly associated with a blunted lumbar spine (LS) bone mineral density (BMD) response to daily treatment with teriparatide, although the impact was limited. INTRODUCTION: Some osteoporosis patients do not respond to teriparatide treatment. To better understand the factors underlying treatment nonresponses, we compared nonresponders' and responders' characteristics. METHODS: We retrospectively analyzed 354 male and female patients with osteoporosis who were administered teriparatide (20 µg/day) for 24 months. The patients were categorized as responders (≥3 % lumber spine (LS) bone mineral density (BMD) increase) or nonresponders (<3 % LS BMD increase), and the groups were compared. RESULTS: The univariate analyses determined that prior bisphosphonate use, a lower baseline procollagen type I N-terminal propeptide (PINP) concentration and a lower urinary N-telopeptide of type I collagen (uNTX) concentration at baseline were significantly associated with teriparatide nonresponses, but these factors were not significant following multivariate analysis. Diminished early increases in the bone turnover markers (BTMs) were also related to nonresponses after teriparatide treatment began. In the nonresponders, the mean (standard deviation (SD)) absolute LS and femoral neck (FN) BMD changes were -0.002 g/cm(2) (0.032) and -0.010 g/cm(2) (0.045), respectively. In the responders, the mean (SD) absolute LS and FN BMD changes were 0.118 g/cm(2) (0.056) and 0.021 g/cm(2) (0.046), respectively. The serum PINP and uNTX levels increased rapidly in both groups, but the responders showed higher early absolute serum PINP and uNTX increases. CONCLUSIONS: The factors associated with nonresponses were prior bisphosphonate use, lower baseline BTM levels, and lower early increases in the BTMs after starting teriparatide treatment, but the impact of these factors on achieving a ≥3 % LS BMD increase at 24 months was limited.

Usefulness of daily teriparatide treatment in elderly patients over 80 years of age.

UNLABELLED: The percent and absolute lumbar spine and femoral neck bone mineral densities and procollagen type I N-terminal propeptide (PINP) and urinary N-telopeptide level increases noted after teriparatide 20 µg/day treatment for 24 months were similar in the older (age ≥ 80 years) and younger (age < 80 years) subgroups. INTRODUCTION: Many individuals are living into their eighth and ninth decades, but little is known about the efficacy of osteoporosis medication for this population. We retrospectively compared usefulness of daily teriparatide therapy in osteoporosis patients ≥80 and <80 years to detect possible age-related differences. METHODS: We analyzed 628 osteoporosis patients treated with teriparatide 20 µg/day for 24 months. The primary efficacy measures were changes in lumbar spine (LS) and femoral neck (FN) bone mineral density (BMD) over 24 months. Changes in serum procollagen type I N-terminal propeptide levels and urinary N-telopeptide (uNTX) excretion were also measured. Patients were divided into age subgroups (older, ≥80 years; younger, <80 years) for BMD and bone turnover marker comparison. RESULTS: In the older subgroup, the percent LS BMD significantly increased by 14.6 ± 10.4 % (mean ± SD) and FN BMD significantly increased by 4.5 ± 10.7 % at 24 months. In the younger subgroup, the percent LS BMD significantly increased by 12.2 ± 8.5 % and FN BMD significantly increased by 2.9 ± 8.3 % at 24 months. In the older subgroup, the mean absolute LS BMD change was 0.111 ± 0.071 g/cm(2) and FN BMD change was 0.019 ± 0.043 g/cm(2). In the younger subgroup, the mean absolute LS BMD change was 0.098 ± 0.065 g/cm(2) and FN BMD change was 0.016 ± 0.045 g/cm(2). The percent and absolute BMD increases in LS and FN and changes in PINP and uNTX were similar between the subgroups. CONCLUSIONS: The usefulness of daily teriparatide treatment is not age dependent.

Argatroban more effectively inhibits the thrombin activity in synovial fluid than naturally occurring thrombin inhibitors.

The purpose of this study was to clarify the precise effect of argatroban on the inhibition of cytokine secretion induced by thrombin on synovial cells. The efficiency of thrombin inactivation by thrombin inhibitors was evaluated in human synovial fluids (SFs). In SFs from 13 osteoarthritis (OA) and 11 rheumatoid arthritis (RA) patients, thrombin, Factor Xa (FXa), plasmin activity, IL-6, MMP-3, VEGF, and D-dimer concentrations were measured. Tissue factor (TF) activity or IL-6, MMP-3, and VEGF secretion of human synovial cells with or without thrombin and argatroban were measured. The efficiency of thrombin inactivation in SFs was compared for thrombin inhibitors: argatroban, antithrombin III (ATIII), or heparin cofactor II (HCII). In SFs, thrombin, FXa, plasmin, D-dimer, IL-6, and MMP-3 were significantly higher in RA than in OA. In synovial cell experiments, TNF-alpha and thrombin enhanced TF activity on the cell surface, and IL-6, MMP-3, and VEGF secretion were enhanced by thrombin. Increased TF activity, and IL-6, MMP-3, and VEGF secretion induced by thrombin were inhibited by argatroban. In SFs, argatroban inactivated thrombin more effectively than ATIII or HCII. Since thrombin plays an important role in the disease activity of OA and RA, it is a potential therapeutic molecular target. Argatroban was the most effective anticoagulant to inhibit thrombin activity in SF. Intra-articular injection is ideal administration because it can deliver high dose of argatroban without high risk of systematic complication.

Synthesis, crystal structure and phase transition of a Xe-N2 compound at high pressure: experimental indication of orbital interaction between xenon and nitrogen.

The van der Waals compound Xe(N2)2 with a C15 Laves structure was successfully synthesised at pressures greater than 4.4 GPa. We found that, at 10 GPa, the structure reversibly transforms from a cubic to a tetragonal phase. Further compression results in changes of Xe-N compound, which could result in the enhancement of orbital interactions between the xenon and nitrogen atoms.

Analysis of daily teriparatide treatment for osteoporosis in men.

UNLABELLED: The percent and absolute lumbar spine and femoral neck bone mineral densities and absolute procollagen type I N-terminal propeptide (PINP) increases following a 20-µg/day teriparatide treatment for 12 months were similar in men and women regardless of sex differences. INTRODUCTION: Several placebo-controlled studies have measured the effects of daily teriparatide in men and postmenopausal women with osteoporosis but none have directly compared the effects between these groups. We retrospectively compared the effects of daily teriparatide therapy in men and postmenopausal women with osteoporosis and investigated biochemical markers of bone turnover to detect possible sex differences. METHODS: Patients (563; 75 men and 488 women) with osteoporosis were retrospectively investigated. All patients were administered with teriparatide at 20 µg/day for 12 months. The primary efficacy measure was changed in lumbar spine (LS) and femoral neck (FN) bone mineral density (BMD) after 12 months of treatment. The change in serum levels of procollagen type I N-terminal propeptide (PINP) and urinary N-telopeptide (uNTX) excretion after 4, 8 and 12 months of treatment were also measured. RESULTS: In men, the percent LS BMD significantly increased by 11.3 ± 9.9 % (mean ± standard deviation (SD)) and the FN BMD increased by 0.4 ± 6.4 % without a significant difference at 12 months. In postmenopausal women, the percent LS BMD significantly increased by 9.6 ± 8.1 % and the FN BMD significantly increased by 2.4 ± 7.8 % at 12 months. The percent and absolute BMD increases in LS and FN between men and women were similar. The absolute increases in PINP were similar in both groups at 4, 8 and 12 months. However, the absolute increases in uNTX were significantly lower in men than in women at 8 and 12 months. CONCLUSION: Daily teriparatide treatment was as effective in men as in postmenopausal women regardless of sex differences.

Dried, ground banana plant leaves (Musa spp.) for the control of Haemonchus contortus and Trichostrongylus colubriformis infections in sheep.

To evaluate the anthelmintic effect of Musa spp. leaves, 12 animals were artificially infected with Haemonchus contortus, and another 12 animals were infected with Trichostrongylus colubriformis. Then, both treatment groups were offered 400 g of dried ground banana plant leaves, and the control animals were offered only 1000 g of coast cross hay. During the trials, the animals received weekly physical examinations. The methods used to evaluate the efficiency of this treatment were packed cell volume, total plasma protein and faecal egg counts, and egg hatchability tests were performed on days -2, +3, +6, +9, +13 and +15. Coproculture tests were performed on day -2 to confirm monospecific infections. In the FEC and EHT, a statistically significant difference (0.04, 0.005; p < 0.05) was noted for T. colubriformis. There were no statistically significant differences (p > 0.05) for Haemochus contortus group in all tests. Our results confirmed previous findings suggesting that dried ground banana plant leaves possess anthelmintic activity.

An algorithm using the early changes in PINP to predict the future BMD response for patients treated with daily teriparatide.

UNLABELLED: About two thirds of patients with a procollagen type I N-terminal propeptide (PINP) increase of >80 µg/l at 1 month after starting teriparatide therapy showed a ≥10 % increase in lumbar spine (LS) bone mineral density (BMD) from baseline at 12 months. We recommend this algorithm as an aid in the clinical management of patients treated with daily teriparatide. INTRODUCTION: An algorithm using PINP is provided in osteoporotic patients with teriparatide treatment. The correlations between the early changes in PINP and the subsequent BMD changes after daily teriparatide therapy were studied to develop an algorithm to monitor patients. METHODS: We evaluated whether early changes in PINP correlated with the changes in BMD at 12 months and developed an algorithm using the early changes in PINP to predict the upcoming BMD increases. RESULTS: The highest correlation coefficient for the relationship between PINP and LS BMD response was determined for the absolute change in PINP at 1 month and the percent change in LS BMD at 12 months (r = 0.36, p <0.01). Using a receiver operator curve analysis, we determined that an 80 µg/l increase in PINP was the most convenient predictor of a 10% increase in LS BMD from baseline (area under curve = 0.72). Using a cut-off value of 80 µg/l, the positive predictive value for predicting a 10% increase in LS BMD from baseline to 12 months was 65%. CONCLUSION: Greater short-term changes in PINP with teriparatide therapy are associated with greater 12-month increases in LS BMD. About two thirds of patients with a PINP increase of >80 µg/l at 1 month after starting treatment showed a ≥10 % increase in LS BMD from baseline at 12 months. We recommend this algorithm as an aid in the clinical management of patients treated with teriparatide.

Efficacy of the dynamic radiographs for diagnosing acute osteoporotic vertebral fractures.

UNLABELLED: We investigated the efficacy of dynamic radiographs for diagnosing acute osteoporotic vertebral fractures (OVFs) compared with supine radiographs or sitting radiographs alone. Evaluation of the dynamic radiographs was superior to the other evaluations. Dynamic radiographs provide a convenient and useful method of diagnosing acute OVFs. INTRODUCTION: Identifying acute OVFs on plain radiographs is difficult. We studied a new approach to identify acute OVFs on the basis of fracture mobility. METHODS: We performed a retrospective radiographic analysis of 472 acute OVFs (<3 weeks after onset), which were diagnosed on the basis of magnetic resonance imaging of T5 through L5 (a total of 5,239 vertebrae). Supine lateral radiographs were compared with sitting lateral radiographs to determine the presence or absence of mobility. Vertebrae showing changes in the vertebral body height were diagnosed as acute OVFs. We analyzed the diagnostic accuracy on the basis of comparative supine and sitting lateral radiographs and compared it with that of radiographs obtained in the supine or the sitting position alone. RESULTS: Of the 472 acute OVFs diagnosed, 313 (66 %) exhibited vertebral mobility on supine lateral and sitting lateral radiographs. Correct diagnoses of acute OVFs or no acute OVFs were made in 4,883 vertebrae. There were 159 unreadable OVFs (3 %), and 197 previous OVFs (4 %) were misdiagnosed as acute OVFs. The sensitivity was 66 % and the specificity was 96 %. Evaluation of the mobility of acute OVFs in the supine and the sitting position was superior to evaluation using radiographs in either the supine or the sitting position alone. CONCLUSIONS: Dynamic radiographs provide a convenient way to identify acute OVFs.

Measurement of the cosmic microwave background polarization lensing power spectrum with the POLARBEAR experiment.

Gravitational lensing due to the large-scale distribution of matter in the cosmos distorts the primordial cosmic microwave background (CMB) and thereby induces new, small-scale B-mode polarization. This signal carries detailed information about the distribution of all the gravitating matter between the observer and CMB last scattering surface. We report the first direct evidence for polarization lensing based on purely CMB information, from using the four-point correlations of even- and odd-parity E- and B-mode polarization mapped over ∼30 square degrees of the sky measured by the POLARBEAR experiment. These data were analyzed using a blind analysis framework and checked for spurious systematic contamination using null tests and simulations. Evidence for the signal of polarization lensing and lensing B modes is found at 4.2σ (stat+sys) significance. The amplitude of matter fluctuations is measured with a precision of 27%, and is found to be consistent with the Lambda cold dark matter cosmological model. This measurement demonstrates a new technique, capable of mapping all gravitating matter in the Universe, sensitive to the sum of neutrino masses, and essential for cleaning the lensing B-mode signal in searches for primordial gravitational waves.

Evidence for gravitational lensing of the cosmic microwave background polarization from cross-correlation with the cosmic infrared background.

We reconstruct the gravitational lensing convergence signal from cosmic microwave background (CMB) polarization data taken by the Polarbear experiment and cross-correlate it with cosmic infrared background maps from the Herschel satellite. From the cross spectra, we obtain evidence for gravitational lensing of the CMB polarization at a statistical significance of 4.0σ and indication of the presence of a lensing B-mode signal at a significance of 2.3σ. We demonstrate that our results are not biased by instrumental and astrophysical systematic errors by performing null tests, checks with simulated and real data, and analytical calculations. This measurement of polarization lensing, made via the robust cross-correlation channel, not only reinforces POLARBEAR auto-correlation measurements, but also represents one of the early steps towards establishing CMB polarization lensing as a powerful new probe of cosmology and astrophysics.

Production of functional coagulation factor VIII from iPSCs using a lentiviral vector.

The use of induced pluripotent stem cells (iPSCs) as an autologous cell source has shed new light on cell replacement therapy with respect to the treatment of numerous hereditary disorders. We focused on the use of iPSCs for cell-based therapy of haemophilia. We generated iPSCs from mesenchymal stem cells that had been isolated from C57BL/6 mice. The mouse iPSCs were generated through the induction of four transcription factor genes Oct3/4, Klf-4, Sox-2 and c-Myc. The derived iPSCs released functional coagulation factor VIII (FVIII) following transduction with a simian immunodeficiency virus vector. The subcutaneous transplantation of iPSCs expressing FVIII into nude mice resulted in teratoma formation, and significantly increased plasma levels of FVIII. The plasma concentration of FVIII was at levels appropriate for human therapy at 2-4 weeks post transplantation. Our data suggest that iPSCs could be an attractive and prospective autologous cell source for the production of coagulation factor, and that engineered iPSCs expressing coagulation factor might provide a cell-based therapeutic strategy appropriate for haemophilia.

A Japanese pediatric patient with coexisting systemic lupus erythematosus and familial Mediterranean fever.

This case report describes a Japanese girl with systemic lupus erythematosus who had recurrent fevers and erythema nodosum. She was later found to carry the complex allele E148Q/R202Q/P369S/R408Q of MEFV, the gene responsible for familial Mediterranean fever.
