High-Grade Serous Ovarian Cancer (HGSOC) originates from fallopian tube (FT) precursors. However, the molecular changes that occur as precancerous lesions progress to HGSOC are not well understood. To address this, we integrated high-plex imaging and spatial transcriptomics to analyze human tissue samples at different stages of HGSOC development, including p53 signatures, serous tubal intraepithelial carcinomas (STIC), and invasive HGSOC.

Porous coordination polymers with excellent molecular sieving ability, high dispersibility, and good compatibility with engineered polymer matrices hold promise for various industrial applications, such as gas separation and battery separators. Here, an in situ defect engineering approach is proposed for highly processable cobalt (Co)-based zeolitic imidazolate frameworks (ZIFs) with enhanced molecular sieving ability and water stability. By varying alkylamine (AA) modulators, the pore structures and textural properties of ZIFs can be fine-tuned.

: This study aimed to investigate the association between insulin resistance, as measured by the triglyceride-glucose index (TyG index), and hearing impairment in middle-aged women in Korea. : This cross-sectional survey utilized data from the Korea National Health and Nutrition Examination Survey (KNHANES) IV (2007-2009), specifically from the period after July 21, 2009, when hearing test results became available, and from the KNHANES V (2010-2012). This study was conducted on 5416 women aged 40 to 69 who had completed both the health examination survey and audiometric tests, excluding those with missing data on menopausal status and the use of hormone replacement therapy.

Endo-β-1,3-glucanase is a glycoside hydrolase (GH) that plays an essential role in the mineralization of β-glucan polysaccharides. In this study, the novel gene encoding an extracellular, non-modular GH16 endo-β-1,3-glucanase (GluH) from PAMC 29290 isolated from Arctic marine sediment was discovered through an analysis of its whole genome sequence and subsequently overexpressed in BL21. The 870-bp GluH gene encoded a protein featuring a single catalytic GH16 domain that shared over 61% sequence identity with uncharacterized endo-β-1,3-glucanases from diverse species, as recorded in the National Center for Biotechnology Information database.

The Gfo/Idh/MocA family enzyme DgpA was known to catalyze the regiospecific oxidation of puerarin to 3"-oxo-puerarin in the presence of 3-oxo-glucose. Here, we discovered that D3dgpA, cloned from the human gut bacterium sp. MRG-IFC3, catalyzed the regiospecific oxidation of various -/-glycosides, including puerarin, in the presence of methyl β-D-3-oxo-glucopyranoside.

Human gut bacterium sp. MRG-IFC3 is unique in that it is capable of metabolizing puerarin, an isoflavone -glycoside, whereas it shows broad substrate glycosidase activity for the various flavonoid -glycosides. To address the question on the substrate specificity, as well as biochemical characteristics, cell-free biotransformation of flavonoid glycosides was performed under various conditions.

Stathmins are small, unstructured proteins that bind tubulin dimers and are implicated in several human diseases, but whose function remains unknown. We characterized a new stathmin, STMND1 (Stathmin Domain Containing 1) as the human representative of an ancient subfamily. STMND1 features a N-terminal myristoylated and palmitoylated motif which directs it to membranes and a tubulin-binding stathmin-like domain (SLD) that contains an internal nuclear localization signal.

In this study, three nitrogen-containing aluminum-based metal-organic frameworks (Al-MOFs), namely, CAU-10pydc, MOF-303, and KMF-1, were investigated for the efficient separation of a CH/CO gas mixture. Among these three Al-MOFs, KMF-1 demonstrated the highest selectivity for CH/CO separation (6.31), primarily owing to its superior CH uptake (7.

The typical Korean diet contains a significant quantity of owing to its unique taste and health benefits. However, the presence of anti-nutritional and toxic substances, such as biogenic amines and microbial pathogens, in has resulted in a loss of revenue and poor consumer health. The present study focused on the identification and quantification of different biogenic amines, pathogenic , and yeast counts in 36 products (designated as De-1 to De-36, 500 g each) procured from the different cottage industries situated in different parts of the Republic of Korea.

Nuclear atypia, including altered nuclear size, contour, and chromatin organization, is ubiquitous in cancer cells. Atypical primary nuclei and micronuclei can rupture during interphase; however, the frequency, causes, and consequences of nuclear rupture are unknown in most cancers. We demonstrate that nuclear envelope rupture is surprisingly common in many human cancers, particularly glioblastoma.

  • Antibody-drug conjugates (ADCs) are designed to deliver chemotherapeutic agents to specific cancer cells, and recent research shows that even low levels of target proteins like HER2 can lead to effective treatment in certain brain tumors.
  • A study analyzing gene expression data from over 500 CNS tumors revealed that various tumor types express different ADC targets, with ependymomas having high HER2 levels, while meningiomas and other tumors exhibited specific patterns of target protein expression.
  • The findings suggest that understanding the unique expression profiles of ADC targets in CNS tumors can guide future treatment strategies and help develop new therapies tailored for specific cancer types.

Water and other small molecules frequently coordinate within metal-organic frameworks (MOFs). These coordinated molecules may actively engage in mass transfer, moving together with the transport molecules, but this phenomenon has yet to be examined. In this study, we explore a unique water transfer mechanism in UTSA-280, where an incoming water molecule can displace a coordinated molecule for mass transfer.

Structural flexibility is a critical issue that limits the application of metal-organic framework (MOF) membranes for gas separation. Herein we propose a mixed-linker approach to suppress the structural flexibility of the CAU-10-based (CAU = Christian-Albrechts-University) membranes. Specifically, pure CAU-10-PDC membranes display high separation performance but at the same time are highly unstable for the separation of CO/CH.

  • - The study evaluated visual outcomes of Ahmed glaucoma valve implantation (AGVI) in patients with neovascular glaucoma (NVG) following diabetic vitrectomy, finding that while intraocular pressure (IOP) was successfully controlled in most cases, many patients experienced unfavorable visual outcomes.
  • - Two groups were analyzed: Group 1 had uncontrolled NVG (high IOP > 30 mmHg), and Group 2 had initially responsive NVG but eventually required AGVI. Delayed surgery in Group 1 (over one week after NVG diagnosis) correlated with worse visual results.
  • - The conclusion emphasized the importance of timely surgical intervention, suggesting that AGVI should ideally occur within six days of NVG diagnosis to help maintain vision

Soybean (SB) leaves (SLs) contain diverse flavonoids with health-promoting properties. To investigate the chemical constituents of SB and their correlations across phenotypes, growing periods, and environmental factors, a validated separation method for mass detection was used with targeted metabolomics. Thirty-six polyphenols (1 coumestrol, 5 flavones, 18 flavonols, and 12 isoflavones) were identified in SLs, 31 of which were quantified.

Congenital hyperinsulinism (CHI) is a rare genetic condition characterized by uncontrolled insulin secretion, resulting in hypoglycemia. Although glucagon has lately been regarded as a therapeutic option for CHI, its use is severely hampered by its poor solubility and stability at physiological pH, as well as its short duration of action. To address these constraints, we developed HM15136, a novel long-acting glucagon analog composed of a glucagon analog conjugated to the Fc fragment of human immunoglobulin G4 via a polyethylene glycol linker.

  • Researchers developed a new method to create zeolitic imidazolate framework (ZIF) nanoparticles called Sogang ZIF-8 (SZIF-8) to improve separation of C2H6/C2H4 gases.
  • SZIF-8 is made with zinc metals coordinated with three ligands—tri-butyl amine (TBA), 2,4-dimethylimidazole (DIm), and 2-methylimidazole (MIm)—and varying amounts of DIm lead to better coordination and reduced motion, enhancing its effectiveness.
  • When combined with a polyimide (6FDA), the SZIF-8(13) membrane achieved impressive C2H6 permeability and selectivity
