Synergism of Light-Induced [4 + 4] Cycloaddition and Electron Transfer Toward Switchable Photoluminescence and Single-Molecule Magnet Behavior in a Dy4 Cubane.

Molecular materials possessing switchable magneto-optical properties are of great interest due to their potential applications in spintronics and molecular devices. However, switching their photoluminescence (PL) and single-molecule magnet (SMM) behavior via light-induced structural changes still constitutes a formidable challenge. Here, a series of cubane structures were synthesized via self-assembly of 9-anthracene carboxylic acid (HAC) and rare-earth ions. All complexes exhibited obvious photochromic phenomena and complete PL quenching upon Xe lamp irradiation, which were realized via the synergistic effect of photogenerated radicals and [4 + 4] photocycloaddition of the AC components. The quenched PL showed the largest fluorescence intensity change (99.72%) in electron-transfer photochromic materials. A reversible decoloration process was realized via mechanical grinding, which is unexpectedly in the electron-transfer photochromic materials. Importantly, an SMM behavior of the Dy analog was observed after room-temperature irradiation due to the photocycloaddition of AC ligands and the photogenerated stable radicals changed the electrostatic ligand field and magnetic coupling. Moreover, based on the remarkably photochromic and photoluminescent properties of these compounds, 2 demos were applied to support their application in information anti-counterfeiting and inkless printing. This work, for the first time utilizing the simultaneous modulation of photocycloaddition and photogenerated radicals in one system, realizes complete PL quenching and light-induced SMM behavior, providing a dynamical switch for the construction of multifunctional polymorphic materials with optical response and optical storage devices.

ABSTRACT Introduction Studies have shown that physical exercise is beneficial to people's overall physical and mental health, but few research reports on the effects of different physical exercises on people's human health. Object The paper explores the difference in human health function between people who adhere to traditional health sports and those who rarely exercise and provide a scientific basis for applying and promoting traditional health sports in TCM "prevention of disease". Methods The paper surveyed 526 people who regularly participate in physical exercises and rarely exercise. The exercise items are divided into Tai Chi/Tai Chi sword group, Health Qigong Baduanjin group, Health Qigong Wuqinxi group, and Health Qigong Yijin group. Warp group, walking/jogging group.

Betatrophin Levels were Increased in Pregnant Women with or without Gestational Diabetes Mellitus and Associated with Beta Cell Function.

Purpose betatrophin has been reported to boost ß cell expansion in insulin resistant states. Pregnancy is a well-recognized physiological state of insulin resistance. Betatrophin levels in pregnant women and their relationships with metabolic variables remain to be elucidated. Methods A total of 49 pregnant women and 31 age-matched unpregnant women with normal glucose regulation (UP-NGR) were included. Among these subjects, according to results from 75 g oral glucose tolerance test (OGTT), 22 women were diagnosed as having gestational diabetes mellitus (GDM). Results Our study found that pregnant women, regardless of their glucose regulation status, had remarkably higher triglycerides (TG), total cholesterol (TC), fasting insulin (FINS), homeostasis model assessment of insulin resistance (HOMA-IR) and homeostasis model assessment of ß-cell function (HOMA-ß). However, GDM patients had much lower HOMA-ß compared with those of pregnant women with normal glucose regulation (P-NGR). Participants of the P-NGR group had almost 4 times higher levels of betatrophin than those of the UP-NGR group. Although betatrophin levels were lower in the GDM group than those of the P-NGR group, the difference did not reach statistical significance. Spearman correlation analysis showed that betatrophin levels were positively and significantly associated with total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-c), FINS and HOMA-ß. However, adjustments of TC, TG and HDL-c eliminated the association between HOMA-ß and betatrophin. Conclusions Pregnant women have significantly higher betatrophin levels in comparison to unpregnant women. Betatrophin levels are positively and significantly associated with ß cell function and lipid levels. Furthermore, lipids may contribute to the association between betatrophin and ß cell function.

Abstract Purpose betatrophin has been reported to boost β cell expansion in insulin resistant states. Pregnancy is a well-recognized physiological state of insulin resistance. Betatrophin levels in pregnant women and their relationships with metabolic variables remain to be elucidated. Methods A total of 49 pregnant women and 31 age-matched unpregnant women with normal glucose regulation (UP-NGR) were included. Among these subjects, according to results from 75 g oral glucose tolerance test (OGTT), 22 women were diagnosed as having gestational diabetes mellitus ( GDM ). Results Our study found that pregnant women, regardless of their glucose regulation status, had remarkably higher triglycerides (TG), total cholesterol (TC), fasting insulin (FINS), homeostasis model assessment of insulin resistance (HOMA-IR) and homeostasis model assessment of β-cell function (HOMA-β). However, GDM patients had much lower HOMA-β compared with those of pregnant women with normal glucose regulation (P-NGR). Participants of the P-NGR group had almost 4 times higher levels of betatrophin than those of the UP-NGR group. Although betatrophin levels were lower in the GDM group than those of the P-NGR group, the difference did not reach statistical significance. Spearman correlation analysis showed that betatrophin levels were positively and significantly associated with total cholesterol, triglycerides, highdensity lipoprotein cholesterol (HDL-c), FINS and HOMA-β.

Resumo Introdução Betatrofina tem sido relacionada à expansão de células β em estado de resistência à insulina. A gravidez é um conhecido estado fisiológico de resistência à insulina. Níveis de betatrofina em gestantes e sua relação com variáveis metabólicas ainda precisam ser esclarecidas. Métodos Um total de 49 gestantes e 31 não gestantes de mesma idade com níveis normais de glicose (UP-NGR) foram incluídas. Dentre elas, de acordo com os resultados da curva glicêmica, base em 75 g, 22 mulheres foram diagnosticadas com diabetes mellitus gestational ( DMG ). Resultados Nosso estudo identificou que gestantes, independente de seus níveis de glicose, tiveram notáveis níveis elevados de triglicerídeos (TG), colesterol (TC), insulina em jejum (FINS), HOMA-IR e HOMA-β. Contudo, pacientes com DMG tiveram bem menos HOMA-β se comparadas às gestantes com níveis normais de glicose ( P-NGR ). Participantes do grupo P-NGR tiveram níveis de betatrofina quase quarto vezes maiores ao das participantes do grupo UP-NGR. Embora os níveis de betatrofina sejam menores no grupo DMG do que no P-NGR, a diferença não obteve significância estatística. Análise da correlação de Spearman demonstrou que os níveis de betatrofina foram positiva e significativamente associados ao TC, TG, HDL-c (high-density lipoprotein cholesterol), FINS e HOMA-β. Contudo, ajustes em TC, TG e HDL-c eliminaram a associação entre HOMA-β e betatrofina. Conclusões Gestantes têm níveis de betatrofina significativamente maiores do que não gestantes. Níveis de betatrofina são positive e significativamente associados às células β funcionais e níveis de lipídeos. Além disso, lipídeos podem contribuir na associação entre betatrofina e células β funcionais.
