タイトル: Complex Genomes of Early Nucleocytoviruses Revealed by Ancient Origins of Viral Aminoacyl-tRNA Synthetases著者: Kijima, Soichiro; Hikida, Hiroyuki; Delmont, Tom O.; Gaïa, Morgan; Ogata, Hiroyuki抄録: Aminoacyl-tRNA synthetases (aaRSs), also known as tRNA ligases, are essential enzymes in translation. Owing to their functional essentiality, these enzymes are conserved in all domains of life and used as informative markers to trace the evolutionary history of cellular organisms. Unlike cellular organisms, viruses generally lack aaRSs because of their obligate parasitic nature, but several large and giant DNA viruses in the phylum Nucleocytoviricota encode aaRSs in their genomes. The discovery of viral aaRSs led to the idea that the phylogenetic analysis of aaRSs can shed light on ancient viral evolution. However, conflicting results have been reported from previous phylogenetic studies: one posited that nucleocytoviruses recently acquired their aaRSs from their host eu ...

タイトル: Sequential Deposition of Diluted Aqueous SnO₂ Dispersion for Perovskite Solar Cells著者: Pylnev, Mikhail; Nishikubo, Ryosuke; Ishiwari, Fumitaka; Wakamiya, Atsushi; Saeki, Akinori抄録: The widespread use of tin dioxide (SnO₂) thin films as electron transport layer (ETL) of perovskite solar cells (PSCs) has been facilitated by commercial SnO₂ nanocolloid dispersion. Nevertheless, challenges such as nanoparticle agglomeration have emerged, impacting film quality and interface properties critical for PSC performance. Herein, the efficacy of sequential, multistep spin-coating of repeatedly diluted SnO₂ aqueous suspension as a simple and effective approach to enhance ETL properties is explored. Through systematic experiments using dynamic light scattering, cyclic voltammetry, optical spectroscopy, and photoconductivity, it is demonstrated that the sequential deposition significantly improves the flatness and coverage of SnO₂, leading to improved electron transpor ...

タイトル: Efficacy and Safety of Branched Chain Amino Acids on Retinitis Pigmentosa: A Randomized, Double-Blind, Placebo-Controlled Clinical Trial著者: Ikeda, Hanako O.; Hasegawa, Tomoko; Abe, Hiroyasu; Amino, Yoko; Nakagawa, Takayuki; Tada, Harue; Miyata, Manabu; Oishi, Akio; Morita, Satoshi; Tsujikawa, Akitaka抄録: Purpose: The aim of this study was to investigate the efficacy and safety of orally administered branched-chain amino acids (BCAAs) on disease progression in patients with retinitis pigmentosa (RP). Methods: A double-blind, randomized, placebo-controlled study was conducted at the Kyoto University Hospital. Seventy patients with RP aged 20 years or above were randomly assigned to the TK-98 (a combination of BCAAs in granule form) or placebo group. One packet (4.15 g) of the study drug was administered orally thrice daily for 78 weeks. Results: There was no significant difference in the rate of change in the total point score, the primary endpoint, between the TK-98 ...

タイトル: Delivery management of pregnant blue rubber bleb nevus syndrome patients: a case report and literature review著者: Nagahama, Mie; Chigusa, Yoshitsugu; Shiraki, Atsuko; Takei, Yui; Yamaguchi, Ayaka; Mizota, Toshiyuki; Komatsu, Maya; Nomura, Takashi; Egi, Moritoki; Mandai, Masaki; Mogami, Haruta抄録: Blue rubber bleb nevus syndrome (BRBNS) is a rare systemic vascular disorder characterized by multifocal venous malformations (VMs). Little is known about the perinatal management of pregnant women with BRBNS owing to the limited number of reported cases. We present the case of a 36-year-old primigravida with BRBNS who underwent an uneventful cesarean section under spinal anesthesia for breech presentation. A thorough systemic examination revealed VMs in various organs, including the skin, conjunctiva, larynx, gastrointestinal tract, lungs, and vulva. Prior to spinal anesthesia, careful examination using imaging modalities was conducted to assess the spinal and epidural inv ...

タイトル: PRDX6 augments selenium utilization to limit iron toxicity and ferroptosis著者: Fujita, Hiroaki; Tanaka, Yu-Ki; Ogata, Seiryo; Suzuki, Noriyuki; Kuno, Sota; Barayeu, Uladzimir; Akaike, Takaaki; Ogra, Yasumitsu; Iwai, Kazuhiro抄録: Ferroptosis is a form of regulated cell death induced by iron-dependent accumulation of lipid hydroperoxides. Selenoprotein glutathione peroxidase 4 (GPX4) suppresses ferroptosis by detoxifying lipid hydroperoxides via a catalytic selenocysteine (Sec) residue. Sec, the genetically encoded [st]21 amino acid, is biosynthesized from a reactive selenium donor on its cognate [[Ser]Sec]tRNA. It is thought that intracellular selenium must be delivered ‘safely’ and ‘efficiently’ by a carrier protein owing to its high reactivity and very low concentrations. Here, we identified peroxiredoxin 6 (PRDX6) as a novel selenoprotein synthesis factor. Loss of PRDX6 decreases the expression of selenoproteins and induces ferroptosis via a reduction in G ...
