Rice with high resistant starch (RS) exhibits the potential to improve glucose metabolism, insulin sensitivity. In this study, using two rice varieties-Samgwang, a medium-amylose rice, and Dodamssal, a high-amylose rice containing RS-we analyzed the composition and molecular structural characteristics of brown rice and its starch and the effects on fasting blood glucose levels, fecal short-chain fatty acid (SCFA), and gut microbiota after 8 weeks of consumption in mice. The amylose content of heat-treated Samgwang (HS) and -Dodamssal (HD) was 21.

The method presented herein is associated with the Lab Resource article titled "Generation of αMHC-EGFP knock-in in human pluripotent stem cell line, SNUe003-A-3, using CRISPR/CAS9-based gene targeting" [1]. The cardiac muscle-specific protein, α-myosin heavy chain (αMHC), is encoded by the human gene, which is expressed in both the atria and ventricles during embryonic development and is predominantly expressed in the atria after birth [2]. Herein, the methods used to achieve CRISPR/SpCas9-mediated introduction of an EGFP reporter into , the target locus in human pluripotent stem cells (hPSCs) for cardiac lineage tracing and clinical cell sorting are described.

Article Synopsis
  • Researchers developed a new method to purify boron nitride nanotubes (BNNTs) without using dispersants by manipulating surface tension and steric repulsion in solvent systems.
  • The optimal purification was achieved using a 70 wt% t-butyl alcohol in water solution, which effectively separated BNNTs from impurities due to solubility differences.
  • The purification process successfully removed up to 93.3% of impurities and revealed a unique liquid crystal phase in the purified BNNTs that was absent in the unpurified version.

Microfiber fabrication via wet-spinning of lyotropic liquid crystals (LCs) with anisotropic nanomaterials has gained increased attention due to the microfibers' excellent physical/chemical properties originating from the unidirectional alignment of anisotropic nanomaterials along the fiber axis with high packing density. For wet-spinning of the microfibers, however, preparing lyotropic LCs by achieving high colloidal stability of anisotropic nanomaterials, even at high concentrations, has been a critically unmet prerequisite, especially for recently emerging nanomaterials. Here, we propose a cationically charged polymeric stabilizer that can efficiently be adsorbed on the surface of boron nitride nanotubes (BNNTs), which provide steric hindrance in combination with Coulombic repulsion leading to high colloidal stability of BNNTs up to 22 wt %.

TUBB3 is a structural neuronal protein important for multiple neuronal functions including axonal guidance and maturation. This study aimed to generate a human pluripotent stem cell (hPSC) line with a TUBB3-mCherry reporter using CRISPR/SpCas9 nuclease. The stop codon in the last exon of TUBB3 was replaced with a T2A-mCherry cassette using CRISPR/SpCas9-mediated homologous recombination.

Protein assemblies have drawn much attention as platforms for biomedical applications, including gene/drug delivery and vaccine, due to biocompatibility and functional diversity. Here, the construction and functionalization of a protein assembly composed of human clathrin heavy chain and light chain for a targeted protein delivery, is presented. The clathrin heavy and light chains are redesigned and associated with each other, and the resulting triskelion unit further self-assembled into a clathrin assembly with the size of about 28 nm in diameter.

  • The new 5th World Health Organization classification for myelodysplastic syndrome (MDS)-associated acute myeloid leukemia (AML) focuses on mutations in myelodysplasia-related (MR) genes instead of just morphological features.
  • In a study with 135 newly diagnosed AML patients, those classified under the 5th edition (AML-MR) were generally older and had worse treatment outcomes compared to those classified under the previous edition (AML-MRC).
  • Key prognostic factors affecting survival included age over 75 years, prior MDS, specific chromosome abnormalities, and mutations in KRAS and ZSZR2, with ZSZR2 mutations noted as significant independent prognostic factors.

eXplainable Artificial Intelligence (XAI) is a new trend of machine learning. Machine learning models are used to predict or decide something, and they derive output based on a large volume of data set. Here, the problem is that it is hard to know why such prediction was derived, especially when using deep learning models.

The assembly of proteins in a programmable manner provides insight into the creation of novel functional nanomaterials for practical applications. Despite many advances, however, a rational protein assembly with an easy scalability in terms of size and valency remains a challenge. Here, a simple bottom-up approach to the supramolecular protein assembly with a tunable size and valency in a programmable manner is presented.

  • Improving drought stress tolerance in soybean can help reduce yield losses in drought-prone areas.
  • The study identified quantitative trait loci (QTLs) linked to drought tolerance by analyzing a specific soybean cross, which involved both a drought-tolerant and a susceptible variety.
  • A total of 10 QTLs were discovered across seven chromosomes, providing valuable genetic markers that can assist in breeding soybean varieties that are more resilient to drought conditions.

  • A previous study found that a mixture called MH increased bone growth in rats, so this study examined its effects on rats missing growth hormone (GH).
  • The researchers measured various growth metrics, including bone lengths and growth factors, after administering either MH or GH for four weeks.
  • The results revealed that MH did not enhance bone growth or influence growth-related factors, unlike GH, indicating that MH and GH work through different biological pathways.

Pod shattering is an important reproductive process in many wild species. However, pod shattering at the maturing stage can result in severe yield loss. The objectives of this study were to discover quantitative trait loci (QTLs) for pod shattering using two recombinant inbred line (RIL) populations derived from an elite cultivar having pod shattering tolerance, namely "Daewonkong", and to predict novel candidate QTL/genes involved in pod shattering based on their allele patterns.

The aim of this study was to investigate the effects of administration of a mixture of (MH) on longitudinal bone growth in normal Sprague Dawley (SD) rats. We measured the femur and tibia length, growth plate area, proliferation of chondrocytes, and expression of insulin-like growth factor-1 (IGF-I) and IGF binding protein-3 (IGFBP-3), and Janus kinase 2 (JAK2)/signal transducer and activator of transcription 5 (STAT5) phosphorylation after dietary administration of MH in SD rats for four weeks. The nose-tail length gain and length of femur and tibia increased significantly in the group that received MH for a period of four weeks.

Due to their outstanding physical properties, perovskite materials are considered to be promising semiconductors for next-generation optoelectronics. However, these materials are often unstable under an ambient atmosphere and ultra-violet illumination. Therefore, the construction of an air-stable visible light transparent perovskite-based ultra-violet photodetector is still highly challenging.
