Increased CSN5 expression enhances the sensitivity to lenalidomide in multiple myeloma cells.

Lenalidomide (LEN) is commonly used as an effective therapeutic agent for multiple myeloma (MM). However, in some patients, primary resistance to LEN is observed, the mechanisms of which remain poorly understood. In this study, we combined a LEN sensitivity assay with proteomics data from 15 MM cell lines to identify protein expression profiles associated with primary LEN resistance.

Effect of Organic Anion Transporting Polypeptide 1B1 on Plasma Concentration Dynamics of Clozapine in Patients with Treatment-Resistant Schizophrenia.

The involvement of drug-metabolizing enzymes and transporters in plasma clozapine (CLZ) dynamics has not been well examined in Japanese patients with treatment-resistant schizophrenia (TRS). Therefore, this clinical study investigated the relationship between single nucleotide polymorphisms (SNPs) of various pharmacokinetic factors (drug-metabolizing enzymes and transporters) and dynamic changes in CLZ. Additionally, we aimed to determine whether CLZ acts as a substrate for pharmacokinetic factors using in vitro assays and molecular docking calculations.

Click Chemistry for Well-Defined Graft Copolymers.

Graft copolymers have gained significant importance in various fields due to their tunable functionality and well-defined architecture. However, there are still limitations due to the compatibility of monomers and functional groups depending on the polymerization mode. Click chemistry has solved this problem through its ability to easily and quantitatively link a wide range of polymers and functional groups.

Genetic population structure of the Asian longhorned tick, Haemaphysalis longicornis, in Japan.

The Asian longhorned tick, Haemaphysalis longicornis Neumann (Ixodida: Ixodidae), is widely distributed across temperate East Asia, including Japan, and carries a variety of zoonotic diseases. The species includes bisexual and parthenogenetic lineages. Various aspects of these two lineages, such as their abundance ratio, genetic relationship, and population structure, remain unknown in island environments such as Japan that are isolated from the mainland.

Phenotypic and Genomic Signatures of Latitudinal Local Adaptation Along With Prevailing Ocean Current in a Coastal Goby.

In the marine realm, unidirectional ocean currents often lead to high migration rates of marine organisms and, therefore, inhibit the formation of their latitudinal genetic structure. In contrast, cryptic latitudinal structures associated with local adaptation may frequently exist in widespread species generally exposed to a strong environmental heterogeneity. However, our understanding of the evolvability of locally adapted populations in open marine environments still needs to be completed.

Subsequent evaluations were conducted at 12, 24, and 96 months.

Dephosphorylation of branched-chain α-keto acid dehydrogenase E1α (BCKDHA) promotes branched-chain amino acid catabolism and renders cancer cells resistant to X-rays by mitigating DNA damage.

Branched-chain amino acids (BCAAs) facilitate cancer cell proliferation and survival. Stresses, including X-irradiation, increase BCAA uptake. However, the role of BCAA metabolism in cancer cell survival remains unclear.

Can NiFe-Layered-Double-Hydroxide Catalysts Suppress Carbon Corrosion in Electrochemical Oxygen Evolution?

Sustainable energy societies demand rechargeable batteries using ubiquitous-material electrodes of geopolitical-risk-free elements. We aim to develop low-overpotential oxygen-evolution-reaction (OER) catalysts that suppress carbon corrosion of gas-diffusion electrodes (GDEs) to realize two-electrode rechargeable Zn-air batteries (r-ZABs). Herein, single-walled-carbon-nanotube (SWNT) thin films are used as a scaffold for a benchmark OER catalyst, doping-free NiFe-layered double hydroxide (NiFeLDHs), operating in r-ZABs using alkali aqueous electrolytes.

An outbreak of influenza A(H1N1)pdm09 antigenic variants exhibiting cross-resistance to oseltamivir and peramivir in an elementary school in Japan, September 2024.

An outbreak of influenza A(H1N1)pdm09 viruses exhibiting cross-resistance to oseltamivir and peramivir occurred in Yokohama, Japan, in September 2024. Among 24 students in a class, 11 were diagnosed with influenza or influenza-like illness, and viruses harbouring the NA H275Y and HA Q210H substitutions were isolated from four. Deep sequencing analysis confirmed the clonal spread of these mutants.

A Novel Matrix-Free Hyperfluorescent System Based on Anti-Quenching TADF Host for High Color Purity MR-TADF Emitters.

Organic light-emitting diodes (OLEDs) based on hyperfluorescent system have attracted widespread attention due to their ability to simultaneously achieve improvements in efficiency, lifetime, and color purity by combining the advantages of high exciton utilization sensitizers and high-color purity emitters. Traditional hyperfluorescent systems typically involve three or four components and are severely sensitive to the doping concentration (≈0.5 wt%) of a terminal emitter, which inevitably causes high costs and difficulties in reproducibility.
