Recyclable and air-stable colloidal manganese nanoparticles catalyzed hydrosilylation of alkenes with tertiary silane.

We synthesized ,-dimethylformamide (DMF)-stabilized manganese nanoparticles (Mn NPs) in a one-step process under air using manganese(ii) chloride as the precursor. The Mn NPs were characterized in terms of particle size, oxidation state, and local structure using annular dark-field scanning transmission electron microscopy (ADF-STEM), X-ray photoelectron spectroscopy (XPS), and X-ray absorption spectroscopy (XAS). The results indicate that Mn NPs are divalent nanosized particles with Mn-O bonds.

Correlation between preoperative aqueous cytokine levels and mid-term corneal endothelial cell loss following penetrating keratoplasty.

Objective: To investigate the association between preoperative aqueous humour (AqH) cytokines and mid-term endothelial cell density (ECD) following penetrating keratoplasty (PKP).

Methods: This study analysed a total of 87 eyes of which 54 underwent PKP and 33 eyes underwent cataract surgery. AqH samples were collected at the beginning of surgery.

DDX1 is required for non-spliceosomal splicing of tRNAs but not of XBP1 mRNA.

RNA helicase DEAD-box helicase 1 (DDX1) forms a complex with the RNA ligase 2´,3´-cyclic phosphate and 5´-OH ligase (RTCB), which plays a vital role in non-spliceosomal splicing of tRNA and X-box binding protein 1 (XBP1) mRNA. However, the importance of DDX1 in non-spliceosomal splicing has not been clarified. To analyze the functions of DDX1 in mammalian cells, we generated DDX1 cKO cells from the polyploid human U2OS cell line and found that splicing of intron-containing tRNAs was significantly disturbed in DDX1-deficient cells, whereas endoplasmic reticulum (ER) stress-induced splicing of XBP1 mRNA was unaffected.

Clinical patterns of vitiligo in Japan: A descriptive study using the JMDC claims database.

Vitiligo is a chronic autoimmune disorder that profoundly impacts patients' quality of life. Real-world data on vitiligo in Japan are limited. This descriptive, cross-sectional study used a claims database to evaluate vitiligo prevalence, patient demographics, treatments, and comorbidities in Japanese patients with vitiligo.
