Nursing Practice and Care Structure for Children and Their Families in Need of Pediatric Palliative and End-of-Life Care in Japan: A Nationwide Survey.

Many nurses experience difficulties in pediatric palliative care practice. The study aimed to describe the current situation and structure of pediatric palliative and end-of-life care nursing practices for children and their families in Japan. The research subjects were nurses working in hospitals; facilities for persons with severe physical, motor, and intellectual disabilities; and home-visit nursing stations.

Identification of RPL15 60S Ribosomal Protein as a Novel Topotecan Target Protein That Correlates with DAMP Secretion and Antitumor Immune Activation.

Damage-associated molecular patterns (DAMPs) contribute to antitumor immunity during cancer chemotherapy. We previously demonstrated that topotecan (TPT), a topoisomerase I inhibitor, induces DAMP secretion from cancer cells, which activates STING-mediated antitumor immune responses. However, how TPT induces DAMP secretion in cancer cells is yet to be elucidated.

Recognition of pathogen-derived sphingolipids in .

In plants, many invading microbial pathogens are recognized by cell-surface pattern recognition receptors, which induce defense responses. Here, we show that the ceramide -ceramide D (Pi-Cer D) from the plant pathogenic oomycete triggers defense responses in . Pi-Cer D is cleaved by an apoplastic ceramidase, NEUTRAL CERAMIDASE 2 (NCER2), and the resulting 9-methyl-branched sphingoid base is recognized by a plasma membrane lectin receptor-like kinase, RESISTANT TO DFPM-INHIBITION OF ABSCISIC ACID SIGNALING 2 (RDA2).

Positive interactions between STAP-1 and BCR-ABL influence chronic myeloid leukemia cell proliferation and survival.

Chronic myeloid leukemia (CML) is a clonal disease characterized by the presence of the Philadelphia chromosome and its oncogenic product, BCR-ABL, which activates multiple pathways involved in cell survival, growth promotion, and disease progression. We recently reported that signal-transducing adaptor protein 1 (STAP-1) is upregulated in CML stem cells (LSCs) and functions to reduce the apoptosis of CML LSCs by upregulating the STAT5-downstream anti-apoptotic genes. In this study, we demonstrate the detailed molecular interactions among BCR-ABL, STAP-1, and signal transducer and activator of transcription 5 (STAT5).

Circadian Clock in Arabidopsis thaliana Determines Flower Opening Time Early in the Morning and Dominantly Closes Early in the Afternoon.

Many plant species exhibit diurnal flower opening and closing, which is an adaptation influenced by the lifestyle of pollinators and herbivores. However, it remains unclear how these temporal floral movements are modulated. To clarify the role of the circadian clock in flower movement, we examined temporal floral movements in Arabidopsis thaliana.
