We discuss the gravitational wave(GW) spectra predicted from the electroweak scalegenesis of the Higgs portal type with a large number of dark chiral flavors, which many flavor QCD would underlie and give the dynamical explanation of the negative Higgs portal coupling required to trigger the electroweak symmetry *** employ the linear-sigma model as the low-energy description of dark many flavor QCD and show that the model undergoes ultra-supercooling due to the produced strong first-order thermal phase transition along the(approximately realized) flat direction based on the Gildener-Weinberg mechanism. Passing through evaluation of the bubble nucleation/percolation, we address the reheating and relaxation processes, which are generically non-thermal and nonadiabatic. Parametrizing the reheating epoch in terms of the e-folding number, we propose proper formulae for the redshift effects on the GW frequencies and signal spectra. It then turns out that the ultra-supercooling predicted from the Higgs-portal scalegenesis generically yields none of GW signals with the frequencies as low as nano Hz,unless the released latent heat is transported into another sector other than reheating the universe. Instead, models of this class prefer to give the higher frequency signals and still keeps the future prospected detection sensitivity, like at LISA, BBO, and DECIGO, etc. We also find that with large flavors in the dark sector, the GW signals are made further smaller and the peak frequencies higher. Characteristic phenomenological consequences related to the multiple chiral scalars include the prediction of dark pions with the mass much less than Te V scale, which is also briefly addressed.

Background and Aims:The clinical introduction of hepcidin25(Hep25)has led to a more detailed understanding of its relationship with ferroportin(FP)and divalent metal transporter1 in primary iron overload syndromes(PIOSs).In 2012,we proposed a classification of PIOSs based on the Hep25/FP system,which consists of prehepatic aceruloplasminemia,hepatic hemochromatosis(HC),and posthepatic FP disease(FP-D).However,in consideration of accumulated evidence on PIOSs,we aimed to renew the ***:We reviewed the 2012 classification and retrospectively renewed it according to new information on ***:Iron-loading anemia was included in PIOSs as a prehepatic form because of the newly discovered erythroferrone-induced suppression of Hep25,and the state of traditional FP-D was remodeled as the BIOIRON *** key molecules responsible for prehepatic PIOSs are low transferrin saturation in aceruloplasminemia and increased erythroferrone production by erythroblasts in iron-loading *** PIOSs comprise four genotypes of HC,in each of which the synthesis of Hep25 is inappropriately reduced in the *** Hep25 synthesis is adequate in posthepatic PIOSs;however,two mutant FP molecules may resist Hep25 differently,resulting in SLC40A1-HC and FP-D,*** phenotypes are diagnosed using laboratory tests,including circulating Hep25,followed by suitable *** sequencing of the candidate genes may be outsourced to gene centers when *** kits for the prevalent mutations,such as C282Y,may be the first choice for a genetic analysis of HC in ***:The revised classification may be useful worldwide.

Ependymoma is a rare and chemotherapy-resistant brain tumor, which has resulted in a delay in the development of drugs to treat it. A subclass of supratentorial ependymomas (ST-EPN), designated ST-EPN-zinc finger-translocation-associated (ZFTA, ST-EPN-ZFTA), exhibits the expression of a fusion protein comprising ZFTA and v-rel reticuloendotheliosis viral oncogene homolog A (RELA), an effector transcription factor of the nuclear factor-kappa B (NF-κB) pathway (ZFTA-RELA). The expression of ZFTA-RELA results in the hyperactivation of the oncogenic NF-κB signaling pathway, which ultimately leads to the development of ST-EPN-ZFTA. To identify inhibitors of the NF-κB signaling pathway activated by the expression of ZFTA-RELA, we used a doxycycline-inducible ZFTA-RELA-expressing NF-κB reporter cell line and found that extracts of the fungus Neosartorya spinosa IFM 47025 exhibited NF-κB inhibitory activity. We identified eight compounds [aszonapyrone A (2), sartorypyrone A (3), epiheveadride (4), acetylaszonalenin (5), (R)-benzodiazepinedione (6), aszonalenin (7), sartorypyrone E (8) and (Z, Z)-N,N’-(1,2-bis[(4-methoxyphenyl)methylene]-1,2-ethanediyl)bis-formamide (9)] from N. spinosa IFM 47025 culture extract using a variety of chromatographic techniques. The structures of these compounds were identified through the analysis of various instrumental data (1D, 2D-NMR, MS, and optical rotation). The NF-κB responsive reporter assay indicated that compounds 2, 3, 5, 7, and 9 exhibited inhibitory activity. We further evaluated the inhibitory activity of these compounds against the expression of endogenous NF-κB responsive genes (CCND1, L1CAM, ICAM1, and TNF) and found that compound 2 showed significant inhibitory activity. Further studies are required to elucidate the mechanism of action of compound 2, which may serve as a lead compound for the development of a novel therapy for ST-EPN-ZFTA.
