Therefore, these results suggest that GR affects the diel rhythmicity of zebrafish larvae at the behavioural and endocrine level, but that these effects are not mediated by changes in the expression of clock-related genes.Hyponatremia is a common electrolyte disorder observed in a wide variety of malignancies and is associated with substantial morbidity and mortality. Newer cancer therapies have improved patient outcomes while also contributing to new cases of hyponatremia. Patients should be monitored closely for the development of vasopressin and non-vasopressin mediated hyponatremia. Acute and symptomatic forms of hyponatremia require urgent intervention, and recent findings also support the correction of chronic "asymptomatic" hyponatremia. Optimizing hyponatremia may reduce medical costs, improve cancer survival, and quality of life. In this manuscript, we review the epidemiology, pathophysiology, etiology, diagnosis and treatment of hyponatremia in the cancer patient.A cypovirus was isolated from larvae of the Japanese peppered moth, Biston robustus. The viral genome is 23,954 bp comprising 10 segmented double-stranded RNAs with a new electropherotype among cypoviruses. Each segment encodes one putative protein and has non-coding regions that contain conserved sequences at their 5' and 3' termini, 5'-AGAA(U/A)U-3' and 5'-UGC-3', respectively. MYK-461 MLCK modulator Seven proteins encoded in the genome are homologous to those of other cypoviruses at a cut-off E-value of 1 × 10-5. The maximal sequence identities of these proteins with cypovirus homologs are 24.30%-39.40%. These results indicate that the virus isolated is a novel cypovirus; herein designated as Biston robustus cypovirus 24 (BrCPV-24). This newly isolated BrCPV-24 infects the larvae of the silkworm Bombyx mori.Background Chikungunya disease, which results in incapacitating arthralgia, has been reported worldwide. We developed a live-attenuated chikungunya virus (CHIKV) vaccine candidate designed for active immunisation of the general population living in endemic regions, as well as serving as a prophylactic measure for travellers to endemic areas. Methods This single-blind, randomised, dose-escalation, phase 1 study investigated as primary outcome safety of a live-attenuated CHIKV vaccine candidate. At two professional clinical trial centres in Illinois and Alabama, USA, healthy volunteers aged 18-45 years were randomly assigned (112) to one of three escalating dose groups (low dose 3·2 × 103 per 0·1 mL; medium dose 3·2 × 104 per 1 mL; or high dose 3·2 × 105 50% tissue culture infection dose per 1 mL) and received a single-shot immunisation on day 0. Individuals in all groups were revaccinated with the highest dose on either month 6 or 12, and followed up for 28 days after revaccination. The safety analysis includemunogenicity profile with 100% seroconversion rates achieved at day 14 (103 [100%] of 103) and sustained for 1 year across all dose groups. Mean peak antibody titres at day 28 ranged from 592·6 to 686·9 geometric mean titres from the low-dose to high-dose groups, respectively. A single vaccination was sufficient to induce sustaining high-titre neutralising antibodies, as shown by the absence of an anamnestic response after any revaccination ranging from 94% to 100% of participants. Following revaccination, vaccinees were protected from vaccine-induced viraemia. Interpretation A novel live-attenuated CHIKV vaccine was well tolerated and highly immunogenic in an adult population and could be an effective intervention for prophylaxis of chikungunya disease worldwide.

Here, we show that conditional deletion of the m6A writer METTL3 in murine fetal liver resulted in hematopoietic failure and perinatal lethality. Loss of METTL3 and m6A activated an aberrant innate immune response, mediated by the formation of endogenous double-stranded RNAs (dsRNAs). The aberrantly formed dsRNAs were long, highly m6A modified in their native state, characterized by low folding energies, and predominantly protein coding. We identified coinciding activation of pattern recognition receptor pathways normally tasked with the detection of foreign dsRNAs. Disruption of the aberrant immune response via abrogation of downstream Mavs or Rnasel signaling partially rescued the observed hematopoietic defects in METTL3-deficient cells in vitro and in vivo. Our results suggest that m6A modification protects against endogenous dsRNA formation and a deleterious innate immune response during mammalian hematopoietic development.Respiratory viruses affect us throughout our lives, from infancy to old age, causing illnesses ranging from a common cold to severe pneumonia. They belong to several virus families, and although many features of infection with these diverse viruses are shared, some have unique characteristics. Here we explain what happens when we are infected by respiratory viruses, including SARS-CoV-2, which causes COVID-19.Background Fever in neutropenia is the most frequent complication of chemotherapy for cancer. The temperature limit defining fever used clinically varies. A higher limit can avoid unnecessary diagnoses in patients spontaneously recovering from fever. This trial primarily aimed to determine if a limit of 39·0°C ear temperature is non-inferior to 38·5°C regarding safety. Methods This cluster-randomised, multiple crossover, non-blinded, non-inferiority trial was done in six Swiss Paediatric Oncology Group centres (clusters) in Switzerland. Patients (aged 1 to less then 18 years) with any malignancy and treated with myelosuppressive chemotherapy expected to last 2 months or more were repeatedly randomly assigned (11), at the cluster level, to either monthly 39·0°C or 38·5°C ear temperature limits for diagnosis of fever in neutropenia. Diagnosis below the randomised limit was allowed for clinical reasons. Such a diagnosis implied emergency hospitalisation, examinations (including blood culture), as-needed antipyretics, and empirical intravenous broad-spectrum antibiotics.
