Microbial indigo reduction is a key reaction in indigo dyeing; however, the mechanism of the interaction with indigo remains unclear. We hypothesized that lignin is a candidate substance that supports this interaction. The addition of lignin effectively enhanced the indigo reduction.

X-linked NF-κB essential modulator (NEMO) deficiency is a primary immunodeficiency characterized by combined immunodeficiency and ectodermal dysplasia. Monocytes from the patients demonstrate a severely impaired response to tissue necrosis factor or lipopolysaccharide, whereas hyper-inflammation is found in some patients. Juvenile myelomonocytic leukemia (JMML) is a pediatric malignancy caused by hypersensitivity to granulocyte-macrophage colony-stimulating factor (GM-CSF) and aberrant RAS signaling activation.

Article Synopsis
  • Ovarian clear cell carcinoma (OCCC) is a tough-to-treat gynecological cancer that shows resistance to chemotherapy, with its underlying mechanisms not fully understood.
  • Recent research combined single-cell analyses and spatial transcriptomics on surgical specimens to identify a resistant subpopulation of OCCC associated with high HIF activity found near cancer-associated fibroblasts (CAFs).
  • The study revealed that the growth factor PDGF contributes to this chemoresistance, and using the drug ripretinib can target CAFs, enhancing the effectiveness of conventional chemotherapy like carboplatin against OCCC.

Article Synopsis
  • The anterior transpetrosal approach has evolved with a new endoscopic technique (eATPA) that offers a less invasive option for removing lesions in the petrous apex region.
  • Between May 2022 and May 2023, eATPA was performed on 10 patients, predominantly involving meningiomas and trigeminal schwannomas, with 8 achieving complete tumor removal.
  • The results showed that eATPA produced similar surgical effectiveness to the traditional microscopic approach (mATPA), with a low incidence of nerve palsy and maintained postoperative quality of life scores.
