Heavy atom effects can be used to enhance intermolecular interaction, regulate quinoidal resonance properties, increase bandwidths, and tune diradical characters, which have significant impacts on organic optoelectronic devices, such as organic field-effect transistors (OFETs), organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), etc. Meanwhile, the introduction of heavy atoms is shown to promote charge transfer, enhance air stability, and improve device performances in the field of organic thermoelectrics (OTEs). Thus, heavy atom effects are receiving more and more attention.

Article Synopsis
  • Tumor Electric Field Therapy (TEFT) shows promise as an effective and safe treatment for glioblastoma but faces challenges in measuring and controlling electric field intensity within tumors.
  • This study utilizes MRI data to create a numerical simulation model that accurately predicts the intracranial electric field generated by TEFT, taking into account the unique electrical properties of different brain tissues.
  • Results indicate that higher load voltage enhances electric field intensity in target areas, while the impact of voltage frequency is minimal, leading to the development of software to optimize TEFT treatment plans.

Article Synopsis
  • Hexafluoroisobutylene (HFIB) is used in various industries but poses toxicity concerns, especially for pregnant women, due to lack of existing data on its effects during pregnancy and fetal development.
  • In an experiment, pregnant rats were exposed to different concentrations of HFIB, revealing that a high concentration of 105.6 ppm caused systemic toxicity, including weight loss and inflammation, along with negative effects on fetal and placental development.
  • The study identifies 105.6 ppm as a toxic level for pregnant rats and fetuses, while 53.5 ppm showed no significant adverse effects, marking it as a safe concentration for pregnancy and fetal health.

Fragmentomic features of circulating cell free mitochondrial DNA (ccf-mtDNA) including fragmentation profile, 5' end base preference and motif diversity are poorly understood. Here, we generated ccf-mtDNA sequencing data of 1607 plasma samples using capture-based next generation sequencing. We firstly found that fragmentomic features of ccf-mtDNA were remarkably different from those of circulating cell free nuclear DNA.

Background: Early detection and effective prognosis prediction in patients with hepatocellular carcinoma (HCC) provides an avenue for survival improvement, yet more effective approaches are greatly needed. We sought to develop the detection and prognosis models with ultra-sensitivity and low cost based on fragmentomic features of circulating cell free mtDNA (ccf-mtDNA).

Participants And Methods: Capture-based mtDNA sequencing was carried out in plasma cell-free DNA samples from 1168 participants, including 571 patients with HCC, 301 patients with chronic hepatitis B or liver cirrhosis (CHB/LC) and 296 healthy controls (HC).

Cordyceps chanhua, an important cordycipitoid medical mushroom with wide use in Asia, has gained attention for its bioactive component beauvericin (BEA), which is of medicinal value as a drug lead, but also of food safety risk. Recent observations by our group revealed a significant decrease of BEA content in C. chanhua when exposed to light, but the underlying regulatory mechanisms remain elusive.

As the global energy structure evolves and clean energy technologies advance, electrocatalysis has become a focal point as a critical conversion pathway in the new energy sector. Transitional metal electrocatalysts (TMEs) with their distinctive electronic structures and redox properties show great potential in electrocatalytic reactions. However, complex reaction mechanisms and kinetic limitations hinder the improvement of energy conversion efficiency, highlighting the necessity for comprehensive studies on structure and performance of electrocatalysts.

Demyelination occurs widely in the central nervous system (CNS) neurodegenerative diseases, especially the multiple sclerosis (MS), which with a complex and inflammatory lesion microenvironment inhibiting remyelination. Sirtuin6 (SIRT6), a histone/protein deacetylase is of interest for its promising effect in transcriptional regulation, cell cycling, inflammation, metabolism and longevity. Here we show that SIRT6 participates in the remyelination process in mice subjected to LPC-induced demyelination.

To investigate the fine starch structure characteristics and formation mechanism of high-quality appearance soft rice, two high-quality and low-quality soft rice varieties (HA-SR and LA-SR, respectively) were selected. Differences in appearance quality, fine starch structure, and activity of key enzymes involved in starch synthesis during the grain-filling stage were compared. The results showed that compared with LA-SR, HA-SR were less chalky, more transparent, had larger starch grains, a lower content of shorter chains (DP 6-24), a higher content of longer chains (DP ≥ 25), lower relative crystallinity, fewer ordered structures, more amorphous structures and larger thicknesses of semi-crystalline lamellae.

Epigenetics plays a crucial role in regulating gene expression during adolescent brain maturation. In adolescents with depression, microglia-mediated chronic neuroinflammation may contribute to the activation of cellular signaling cascades and cause central synapse loss. However, the exact mechanisms underlying the epigenetic regulation of neuroinflammation leading to adolescent depression remain unclear.

Rapid capacity fading, interfacial instability, and thermal runaway due to oxygen loss are critical obstacles hindering the practical application and commercialization of Ni-rich cathodes (LiNiCoMnO, NCM811). Herein, a Sn/F codoping and LiF-coated Ni-rich cathode, denoted as NCM811-SF, is structurally fabricated that demonstrates very high cyclic and thermal stabilities. The introduction of Sn regulates the local electronic structure and facilitates the conversion of the layered structure into a spinel phase; F captures lithium impurities to form LiF coatings and forms TM-F bonds to reduce Ni/Li disordering.

  • Mycotoxins cause immune system damage and disrupt mitochondrial function, but their effects on the RIG-I like receptor (RLR) pathway remain unclear.
  • The study used porcine alveolar macrophages to assess the protective effects of three isomers of chlorogenic acid against mitochondrial damage from combined mycotoxins (Aflatoxin B1, Deoxynivalenol, and Ochratoxin A).
  • Results showed that all isomers helped counteract mycotoxin toxicity, with isochlorogenic acid A being the most effective in preserving mitochondrial balance and enhancing immune response via the RLR pathway.

Despite the importance of surface iron (hydr)oxides (Fe-(hydr)oxides) for the decontamination performance of zerovalent iron (ZVI) -based technologies has been well recognized, controversial understandings of their exact roles still exist due to the complex species distribution of Fe-(hydr)oxides. Herein, we re-structured the surface of ZVI using eight distinct Fe-(hydr)oxides and analyzed their species-specific effects on the performance of ZVI for Se(IV) under well-controlled conditions. The kinetics-relevant performance indicators (Se(IV) removal rates, Fe release rates, and the utilization ratio of ZVI) under the effect of each Fe-(hydr)oxide roughly followed the order: δ-FeOOH > FeHO·4HO > α-FeOOH > β-FeOOH > γ-FeOOH > γ-FeO > FeO > α-FeO.

Backgrounds: Sleep disturbances are prevalent among elderly individuals. While polysomnography (PSG) serves as the gold standard for sleep monitoring, its extensive setup and data analysis procedures impose significant costs and time constraints, thereby restricting the long-term application within the general public. Our laboratory introduced an innovative biomarker, utilizing artificial intelligence algorithms applied to PSG data to estimate brain age (BA), a metric validated in cohorts with cognitive impairments.
