Furthermore, a significant decrease in total protein levels of OCT4 and Nrf2 occurred in skeletal muscle after 4 h recovery. However, essential cofactors of OCT4 and Nrf2 were significantly upregulated during anoxia and/or recovery. Downstream targets of the Nrf2-ARE pathway were evaluated, including glutathione-S-transferases (GSTs) and aldo-keto reductases (AKRs). Significant increases in GSTT1 and GSTP1 were observed in liver and muscle whereas AKRs showed a tissue specific response to both anoxia and recovery from anoxia. This study demonstrates activation of antioxidants as a cell protective mechanism against generation of reactive oxygen species during anoxia in wood frogs. Salinity is an important abiotic factor for aquatic organisms. In fish, changes in salinity affect physiological responses and alter the immune system. Takifugu rubripes is an important economic marine fish, and mechanisms of T. rubripes adaptation to salinity changes need to be further documented. In this study, a transcriptome sequencing technique was used to analyse genes that were differentially expressed in the T. rubripes gill after low-salinity stress for 30 d, and differential gene expression was further validated by quantitative real-time PCR (qPCR). After assembly, 385 differentially expressed genes (DEGs) were identified, including 182 upregulated genes and 203 downregulated genes. The DEGs were assigned to Gene Ontology (GO) classes with a total of 1647 functional terms. Most DEGs were assigned to biological process (984; 59.8%) followed by molecular function (445; 27.0%) and cellular component (218; 13.2%). Further KEGG analysis allocated 385 DEGs to 95 KEGG pathways. After q-value correction, 7 Specialist Palliative Care services (SPCS) have a vital role to play in the global COVID-19 pandemic. Core expertise in complex symptom management, decision-making in uncertainty, advocacy and education, and ensuring a compassionate response are essential, and SPCS are well positioned to take a proactive approach in crisis management planning. SPCS resource capacity is likely to be overwhelmed, and consideration needs to be given to empowering and supporting high-quality primary palliative care in all care locations. Our local SPCS have developed a Palliative Care Pandemic Pack to disseminate succinct and specific information, guidance, and resources designed to enable the rapid up-skilling of non-specialist clinicians needing to provide palliative care. It may be a useful tool for our SPCS colleagues to adapt as we face this global challenge collaboratively. CONTEXT People with acute-on-chronic breathlessness due to cardiorespiratory conditions frequently present to the emergency department (ED) causing burden for the person concerned, their carers and emergency services. NT157 OBJECTIVE To understand the reasons for ED presentation for acute-on-chronic breathlessness and how optimal care might avoid presentations. METHODS Qualitative in-depth linked interviews were conducted as part of a mixed methods study. Transcripts of audio-recordings were subjected to thematic analysis. Consenting patients presenting to a single tertiary hospital ED with acute-on-chronic breathlessness able to be interviewed were eligible. Patient-participants (n=18) were purposively sampled for maximum variation. Patient-participant nominated carers (n=9) and clinicians (n=8) were recruited. RESULTS Theme 1) "The context for the decision to present to the ED" is the experience of acute-on-chronic breathlessness, in which a person faces an existential crisis not knowing where the next breath is coming from, and previous help-seeking experiences. Theme 2) "Reasons for presentation" some were reluctant to seek help until crisis when family carers were often involved in the decision to present. Others had previous poor experiences of help-seeking for breathlessness in the community and turned to the ED by default. Some had supportive primary clinicians and presented to the ED either on their clinician's recommendation or because their clinician was unavailable. CONCLUSIONS The decision to present to the ED is made in the context of serious crisis and previous experiences. Discussion of the reason for presentation may enable better management of chronic breathlessness and reduce the need for future emergency presentation. Eight new meroterpenoids (1-8) featuring β-triketone-conjugated terpenoids, rtomentones A-H, were isolated from the leaves of Rhodomyrtus tomentosa. Structures of the isolates were unambiguously established by a combination of NMR and ECD spectroscopy and X-ray diffraction analysis. Rtomentone C (3) was the first example of aromadendrane-based meroterpenoid containing an oxa-spiro[5.6] ring. Rtomentone D (4) was obtained as a racemic mixture confirmed by chiral HPLC analysis. The cytotoxicity against MDA-MB-231, A549, and DLD-1 cells of all isolates was evaluated. Three new acylated phenylethanoid glycosides, kurroaosides A (14), B (15), and C (16), and a new acylated cucurbitane-type triterpene glycoside, kurroaoside D (17), were isolated from a methanol extract of the rhizomes of Picrorhiza kurroa Royle ex Benth. (Plantaginaceae) along with 29 known isolates including 10 acylated phenylethanoid glycosides (18-27), three cucurbitane-type triterpene glycosides (32-34), and a nortriterpene glycoside (35). The structures of these new compounds (14-17), including their stereochemistry, were determined based on chemical and physicochemical evidence derived from NMR and MS analysis. Among the isolates, acylated iridoid glycosides, picrosides I (8), II (9), III (10), and IV (11) and 6-feruloylcatalpol (12), phenylethanoid glycosides (14-16), triterpene glycosides, cucurbitacin B 2-O-β-D-glucopyranoside (32) and 25-acetoxy-2-β-D-glucopyranosyloxy-3,16,20-trihydroxy-9-methyl-19-norlanosta-5-en-22-one (35), and an acetophenone glycoside, picein (36), significantly promoted collagen synthesis at 10-30 μM, with no cytotoxicity being observed at the effective concentrations. Furthermore, acylated phenylethanoid glycosides, calceolarioside A (19, IC50 = 69.2 μM), plantamajoside (20, 51.8 μM), isoplantamajoside (21, 76.8 μM), and scroside E (23, 65.5 μM), exhibited collagenase inhibitory activity equivalent to that of positive agents caffeic acid (75.6 μM) and epigallocatechin 3-O-gallate (75.4 μM).
