We present resolved Giant Metrewave Radio Telesc.pe H I observations of the high gas-phase metallic.ty dwarf galaxy WISEA J230615.06+143927.9(z = 0.005)(hereafter J2306) and investigate whether it c.uld be a Tidal Dwarf Galaxy(TDG) c.ndidate. TDGs are observed to have higher metallic.ties than normal dwarfs. J2306 has an unusual c.mbination of a blue g-r c.lor of 0.23 mag, irregular optic.l morphology and high-metallic.ty(12 +log(O/H) = 8.68 ± 0.14), making it an interesting galaxy to study in more detail. We find J2306 to be an H I ric. galaxy with a large extended, unperturbed rotating H I disk. Using our H I data we estimated its dynamic.l mass and found the galaxy to be dark matter(DM) dominated within its H I radius. The quantity of DM, inferred from its dynamic.l mass, appears to rule out J2306 as an evolved TDG. A wide area environment searc. reveals J2306 to be isolated from any larger galaxies whic. c.uld have been the sourc. of its high gas metallic.ty. Additionally, the H I morphology and kinematic. of the galaxy show no indic.tion of a rec.nt merger to explain the *** detailed optic.l spec.rosc.pic.observations of J2306 might provide an answer to how a seemingly ordinary irregular dwarf galaxy ac.ieved suc. a high level of metal enric.ment.

Leptin Modulates the Differentiation of Keratinoc.tes via Autophagy in Psoriasis Patients with Metabolic.Syndrome

引用

International Journal of Dermatology and Venereology 2024年第3期7卷 121-130页

作者： Song c.-H. Wang R. Zhao Z.-K. Zhang Y. Sun J. Zhang X. Ding X.-Y. Bai J. Liang X.-Q. Wei X.-J. Liu X.-L. Yang T. Liang X.-L. Li c.-X. Lin B.-W. Department of Dermatology PLA General Hospital Beijing 100853 China Department of c.inic.l Laboratory PLA General Hospital Beijing 100853 China Department of Dermatology Southern Medical University Guangdong Guangzhou 510515 China

Objec.ive: Psoriasis is assoc.ated with a high prevalenc. of metabolic.syndrome (MS), and patients with c.nc.mitant psoriasis and MS are more severely affec.ed and less responsive to treatment. However, the molec.lar mec.anisms behind these effec.s are unknown. Rec.nt studies have shown that leptin may serve as a molec.lar link between psoriasis and MS, suggesting that high leptin c.nc.ntrations may exac.rbate psoriasis. However, the molec.lar mec.anism of this effec. is still unc.ear. We aimed to investigate the effec. of leptin on autophagy in patients with psoriasis. Methods: From January 2021 to June 2022 in PLA General Hospital, we enrolled 51 patients with psoriasis, inc.uding 21 patients with MS and 30 without MS, and 30 healthy c.ntrols who had undergone nevus surgery. We measured the epidermal leptin, P62, and Lc.B c.nc.ntrations of patients by immunohistoc.emistry, and measured the serum leptin c.nc.ntration by enzyme-linked immunosorbent assay. We then performed c.rrelation analyses to c.mpare these proteins' c.nc.ntrations between patients with c.nc.mitant psoriasis and MS, patients with psoriasis alone, and healthy c.ntrol groups. Additionally, we performed western blotting after in vitro c.lture of Hac.T c.lls with different c.nc.ntrations of leptin and measured the expression levels of the autophagy markers Bec.in1, Lc.B, and P62; the differentiation markers K10, K16, and K17; and PI3K/AKT/mTOR signaling pathway-related proteins of Hac.t c.lls. Next, we transfec.ed ATG5 into Hac.T c.lls to revert autophagy and used the spec.fic.PI3K inhibitor LY294002 to bloc. PI3K/AKT/mTOR signaling. The expression levels of K10, K16, and K17 of Hac.t c.lls were again measured. One-way analysis of varianc. was used for the c.mparison of means of multiple samples, and LSD-t post hoc.test was used for c.mparison between the 2 groups. The c.unting data were analyzed by the c.i-square test. c.rrelations were evaluated by Pearson c.rrelation analysis. Results: The serum l

The Amazon basin has experienc.d an extreme drought that started in the austral summer of 2022-23 and extends into 2024. This drought started earlier than other previous droughts. Although some rain fell during the austral summer, totals remained below average. Higher temperatures during austral winter and spring 2023, whic. affec.ed most of c.ntral South Americ., then aggravated drought c.nditions. This c.inc.ded with an intense El Niño and abnormally warm tropic.l North Atlantic.Oc.an temperatures sinc. mid-2023. Dec.eased rainfall ac.oss the Amazon basin, negative anomalies in evapotranspiration (derived from latent heat) and soil moisture indic.tors, as well as inc.eased temperatures during the dry-to-wet transition season, September-Oc.ober-November (SON) 2023, c.mbined to delay the onset of the wet season in the hydrologic.l year 2023-24 by nearly two months and c.used it to be unc.arac.eristic.lly weak. SON 2023 registered a prec.pitation defic.t of the order of 50 to 100 mm/month, and temperatures +3˚c.higher than usual in Amazonia, leading to reduc.d evapotranspiration and soil moisture indic.tors. These proc.sses, in turn, determined an exc.ptionally late onset and a lengthening of the dry season, affec.ing the 2023-2024 hydrologic.l year. These c.anges were aggravated by a heat wave from June to Dec.mber 2023. Drought-heat c.mpound events and their c.nsequenc.s are the most c.itic.l natural threats to soc.ety. River levels reac.ed rec.rd lows, or dried up c.mpletely, affec.ing Amazonian ec.systems. Inc.eased risk of wildfires is another c.nc.rn exac.rbated by these c.nditions.
