Two modular systems were synthesized composed of triphenylamine (ZnTPAP) and pyrene (ZnPyP) covalently linked at meso position of the Zn(II) porphyrins. Both compounds behaved as energy transfer antenna and orthogonal units to enhance the electron donating ability of Zn(II) porphyrins. Detailed photophysical and aggregation studies reveal that an appreciable electronic interaction exists between peripheral units to the porphyrin π-system so that they behave like strong donor materials.

Department of Information and Communication Engineering, Yeungnam University, Gyeongsan, 38541, Republic of Korea.

Thyroid illness encompasses a range of disorders affecting the thyroid gland, leading to either hyperthyroidism or hypothyroidism, which can significantly impact metabolism and overall health. Hypothyroidism can cause a slowdown in bodily processes, leading to symptoms such as fatigue, weight gain, depression, and cold sensitivity. Hyperthyroidism can lead to increased metabolism, causing symptoms like rapid weight loss, anxiety, irritability, and heart palpitations.

Chitosan, the deacetylated form of chitin, is considered a valuable source of compounds in the feed and food industries. However, the impact of Hermetia illucens larvae chitosan (HCS) with specific physicochemical characteristics on obesity mediated by lipid accumulation and microbiome dysbiosis has not been fully elucidated. We purified HCS with a low molecular weight (84 kDa), low crystallinity, and a high deacetylation rate, characterizing it through several analytical techniques, including gel permeation chromatography, FT-IR, H NMR, FE-SEM, and XRD analysis.

The COVID-19 pandemic forced the rapid development of methods to measure humoral and cellular immunity against SARS-CoV-2. The lack of a global standardized protocol and the high variability of intra- and inter-assay precision of the T-cell response made it difficult to compare T-cell assay results with those of other laboratories. The interferon-gamma enzyme-linked immunosorbent spot (IFN-γ ELISpot) assay for immunogenicity evaluation was validated using naturally infected donor peripheral blood mononuclear cells, a commercially available IFN-γ ELISpot kit, and a SARS-CoV-2 specific peptide pool.

FAD and NADPH binding sites of YUCCA6 are essential for chaperone activity and oxidative stress tolerance in Arabidopsis thaliana.

Plant Physiol Biochem

January 2025

Division of Applied Life Science (BK21four), PBRRC, IALS, and RILS, Gyeongsang National University, Jinju, 52828, Republic of Korea. Electronic address:

Phytohormone auxin plays a pivotal role in governing plant growth, development, and responses to abiotic stresses. YUCCA6 (YUC6), an auxin biosynthetic enzyme belonging to the flavin monooxygenase (FMO) subfamily, converts indole-3-pyruvic acid to indole-3-acetic acid. Our prior investigation uncovered that YUC6 also functions as a thiol-reductase and chaperone in a Cys85-dependent manner, resulting in conferred tolerance to nickel heavy metal stress and drought and delayed leaf senescence.

Background And Objectives: The Fractional Flow Reserve and Intravascular Ultrasound-Guided Intervention Strategy for Clinical Outcomes in Patients with Intermediate Stenosis (FLAVOUR) trial demonstrated non-inferiority of fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) compared with intravascular ultrasound (IVUS)-guided PCI. We sought to investigate the cost-effectiveness of FFR-guided PCI compared to IVUS-guided PCI in Korea.

Methods: A 2-part cost-effectiveness model, composed of a short-term decision tree model and a long-term Markov model, was developed for patients who underwent PCI to treat intermediate stenosis (40% to 70% stenosis by visual estimation on coronary angiography).

Efficient wastewater treatment, particularly the removal of heavy metal ions, remains a challenging priority in environmental remediation. This study introduces a novel sandwich-structured nanocomposite, RGO-CuS-PPy, composed of reduced graphene oxide (RGO), copper sulfide (CuS), and polypyrrole (PPy), synthesized via a straightforward hydrothermal method. The unique combination of RGO, CuS, and PPy offers enhanced adsorption capacity for Ni(II) ions due to RGO's high surface area and CuS's active binding sites, supported by PPy's structural stability contributions.

This study aims to verify whether the blood flow velocity and the diameter size, measured through intra-carotid artery Doppler measurements performed on sepsis patients visiting the emergency department, are useful as tools for predicting the risk of early death. As a prospective study, this research was performed on sepsis patients who visited a local emergency medical center from August 2021 to February 2023. The sepsis patients' carotid artery was measured using Doppler imaging, and they were divided into patients measured for the size of systolic and diastolic mean blood flow velocity and diameter size: those measured for their qSOFA (quick sequential organ failure assessment) score and those measured using the SIRS (systemic inflammatory response syndrome) criteria.
