Immune checkpoint inhibitors are not effective for metabolic dysfunction-associated fatty liver disease (MAFLD)-hepatocellular carcinoma (HCC) patients, and identifying the key gut microbiota that contributes to immune resistance in these patients is crucial. Analysis using 16S rRNA sequencing reveals a decrease in Akkermansia muciniphila (Akk) during MAFLD-promoted HCC development. Administration of Akk ameliorates liver steatosis and effectively attenuates the tumor growth in orthotopic MAFLD-HCC mouse models.

In this work, we present the green synthesis of complex - derived from β-hidroxymethylidene indanones by ultrasound, which allowed for the obtaining of compounds in a shorter time and with good yields. These organotin complexes were then doped with cobalt porphine and incorporated into a poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) matrix to manufacture composite semiconductor films. The semiconductor films were characterized through atomic force microscopy, examining their topography, Knoop hardness (around 17 HK), and tensile strength, which varied from 5 × 10 to 7 × 10 Pa.

January 2025

Discovery3 Team, Department of Research and Early Development, GC Biopharma, 93, Ihyeon-ro 30Beon-gil, Giheung-gu, Yongin-si, Gyeonggi-do, South Korea.

Immune-mediated thrombotic thrombocytopenic purpura (iTTP) is a rare and life-threatening blood disorder characterized by the formation of blood clots in small blood vessels. It is caused by antibodies targeting the A disintegrin and metalloprotease with thrombospondin type 1 repeats, member 13 (ADAMTS13), which plays a role in cleaving von Willebrand factor. Most patients with iTTP have autoantibodies against specific domains of the ADAMTS13 protein, particularly the cysteine-rich and spacer domains.

The extraction and analysis of pitch underpin speech and music recognition, sound segregation, and other auditory tasks. Perceptually, pitch can be represented as a helix composed of two factors: height monotonically aligns with frequency, while chroma cyclically repeats at doubled frequencies. Although the early perceptual and neurophysiological mechanisms for extracting pitch from acoustic signals have been extensively investigated, the equally essential subsequent stages that bridge to high-level auditory cognition remain less well understood.

Skin and soft tissue infections (SSTI) include bacterial infections of the skin, muscles, and connective tissue such as ligaments and tendons. SSTI in patients with immunocompromising diseases may lead to chronic, hard-to-heal infected wounds, resulting in disability, amputation, or even death. To treat SSTI and rebuild the defensive barrier of the skin, here we utilize recombinant type XVII collagen protein (rCol XVII) to construct biodegradable, regenerative collagen microneedles (rCol-MNs) for transdermal delivery of antibacterial agents.

Duchenne muscular dystrophy (DMD) is a severe muscle disorder caused by mutations in the DMD gene, leading to dystrophin deficiency. Antisense oligonucleotide (ASO)-mediated exon skipping offers potential by partially restoring dystrophin, though current therapies remain mutation specific with limited efficacy. To overcome those limitations, we developed brogidirsen, a dual-targeting ASO composed of two directly connected 12-mer sequences targeting exon 44 using phosphorodiamidate morpholino oligomers.

Ferroptosis plays a key role in cisplatin-induced acute kidney injury (AKI). Bergenin, which is extracted from Ardisiae Japonicae Herba and has long been used in folk tea and herbal tea drinks, is known to activate Nrf2 and has anti-inflammatory and antioxidant properties, however, its protective influence on CI-AKI has not been elucidated. We used models of cisplatin-induced nephrotoxicity in vitro and CI-AKI models in vivo.

Cyclic GMP-AMP synthase (cGAS)-Stimulator of interferon genes (STING) signaling pathway, an essential element in the innate antiviral immune responses, has emerged as a key component of innate immune system to modulate type I IFNs production and response by recognizing both exogenous and endogenous DNA. Although some cGAS-STING signaling small molecule agonists have been developed, there are few natural polysaccharides reported to activate cGAS-STING signaling for the treatment of infectious diseases. Here, we reported that Laminaran, a low molecular weight β-glucan storage polysaccharide present in brown algae, potentiates cGAS-STING signaling to promote type I IFNs production and antiviral response.

Due to incessant contamination of the groundwater system near the dumpsite in southwestern Nigeria Basement Complex, this study seeks to evaluate the impact of the Odogbo dumpsite on the local groundwater system by integrating geophysical and geochemical methodologies. Aeromagnetic data covering the study area was acquired, processed, and enhanced to delineate basement features that could potentially be passing plumes to the groundwater system. Concurrently, geoelectric methods using 2-D dipole-dipole imaging and vertical electrical sounding (VES) were utilized to characterize the vulnerability indices of the lithologies underlying the dumpsite.

Department of Chinese Language Studies, Centre for Research on Chinese Language and Education, The Education University of Hong Kong, Tai Po, N.T, Hong Kong.

Word recognition is a fundamental reading skill that relies on various linguistic and cognitive abilities. While executive functions (EF) have gained attention for their importance in developing literacy skills, their interaction with domain-specific skills in facilitating reading among different learner groups remains understudied. This study examines the relationship between EF, orthographic awareness, morphological awareness, and Chinese word recognition in 204 Chinese as a second language (CSL) students and 419 native Chinese primary students.

Article Synopsis
  • The transmembrane potential is crucial for cellular functions like signaling and energy production, with Rhodamine voltage reporters (RhoVRs) serving as small, non-invasive sensors that can detect voltage changes, especially in mitochondria.
  • Extensive simulations and free-energy calculations revealed that the orientation of RhoVRs relative to membranes, influenced by their polarized functional groups, significantly impacts their voltage sensitivity and localization within cells.
  • The study's findings on the relationship between the chemical structure of RhoVRs and their membrane behavior offer valuable insights for designing fluorescent dyes that better detect voltage changes.
