The complete genome sequences of 12 isolates of the rare Salmonella enterica serovar Adjame were determined by combining Nanopore and Illumina sequence reads. Anisomycin price Chromosome sizes ranged from 4,597,011 bp to 4,678,052 bp, and the GC content was 52.3%. A virulent plasmid of 87,433 bp was found in only one isolate.Here, we report the genome sequence and characterization for a Blattabacterium strain isolated from the viviparous cockroach, Diploptera punctata, which provides amino acids critical for intrauterine embryo development. The genome was assembled by sequencing of the cockroach fat body, which is the location of this obligate symbiont.Strategies to increase energy expenditure are an attractive approach to reduce excess fat storage and body weight to improve metabolic health. In mammals, uncoupling protein-1 (UCP1) in brown and beige adipocytes uncouples fatty acid oxidation from ATP generation in mitochondria and promotes energy dissipation as heat. We set out to identify small molecules that enhance UCP1 levels and activity using a high-throughput screen of nearly 12,000 compounds in mouse brown adipocytes. We identified a family of compounds that increase Ucp1 expression and mitochondrial activity (including un-coupled respiration) in mouse brown adipocytes and human brown and white adipocytes. The mechanism of action may be through compound binding to A kinase anchoring protein (AKAP) 1, modulating its localization to mitochondria and its interaction with protein kinase A (PKA), a known node in the β-adrenergic signaling pathway. In mice, the hit compound increased body temperature, UCP1 protein levels, and thermogenic gene expression. Some of the compound effects on mitochondrial function were UCP1- or AKAP1-independent, suggesting compound effects on multiple nodes of energy regulation. Overall, our results highlight a role for AKAP1 in thermogenesis, uncoupled respiration, and regulation energy balance.Type-2 diabetes (T2D) is a global disease caused by the inability of pancreatic β-cells to secrete adequate insulin. However, the molecular mechanisms underlying the failure of β-cells to respond to glucose in T2D remains unknown. Here, we investigated the relative contribution of UDP-glucose (UDP-G), a P2Y14-specific agonist, in the regulation of insulin release using human isolated pancreatic islets and INS-1 cells. P2Y14 was expressed in both human and rodent pancreatic β-cells. Dose-dependent activation of P2Y14 by UDP-G suppressed glucose-stimulated insulin secretion (GSIS) and knockdown of P2Y14 abolished the UDP-G effect. 12-h pretreatment of human islets with pertussis-toxin (PTX) improved GSIS and prevented the inhibitory effect of UDP-G on GSIS. UDP-G on GSIS suppression was associated with suppression of cAMP in INS-1 cells. UDP-G decreased the reductive capacity of nondiabetic human islets cultured at 5 mm glucose for 72 h and exacerbated the negative effect of 20 mm glucose on the cell viability during culture period. T2D donor islets displayed a lower reductive capacity when cultured at 5 mm glucose for 72 h that was further decreased in the presence of 20 mm glucose and UDP-G. Presence of a nonmetabolizable cAMP analog during culture period counteracted the effect of glucose and UDP-G. Islet cultures at 20 mm glucose increased apoptosis, which was further amplified when UDP-G was present. UDP-G modulated glucose-induced proliferation of INS-1 cells. The data provide intriguing evidence for P2Y14 and UDP-G's role in the regulation of pancreatic β-cell function.The E6 protein of both mucosal high-risk human papillomaviruses (HPVs) such as HPV-16, which have been causally associated with malignant tumors, and low-risk HPVs such as HPV-11, which cause the development of benign tumors, interacts with the cellular E3 ubiquitin ligase E6-associated protein (E6AP). This indicates that both HPV types employ E6AP to organize the cellular proteome to viral needs. However, whereas several substrate proteins of the high-risk E6-E6AP complex are known, e.g. the tumor suppressor p53, potential substrates of the low-risk E6-E6AP complex remain largely elusive. Here, we report on an affinity-based enrichment approach that enables the targeted identification of potential substrate proteins of the different E6-E6AP complexes by a combination of E3-selective ubiquitination in whole-cell extracts and high-resolution MS. The basis for the selectivity of this approach is the use of a ubiquitin variant that is efficiently used by the E6-E6AP complexes for ubiquitination but not by E6AP alone. By this approach, we identified ∼190 potential substrate proteins for low-risk HPV-11 E6 and high-risk HPV-16 E6. Moreover, subsequent validation experiments in vitro and within cells with selected substrate proteins demonstrate the potential of our approach. In conclusion, our data represent a reliable repository for potential substrates of the HPV-16 and HPV-11 E6 proteins in complex with E6AP.Activated protein C is a trypsin-like protease with anticoagulant and cytoprotective properties that is generated by thrombin from the zymogen precursor protein C in a reaction greatly accelerated by the cofactor thrombomodulin. The molecular details of this activation remain elusive due to the lack of structural information. We now fill this gap by providing information on the overall structural organization of these proteins using single molecule FRET and small angle X-ray scattering. Under physiological conditions, both zymogen and protease adopt a conformation with all domains vertically aligned along an axis 76 Å long and maximal particle size of 120 Å. This conformation is stabilized by binding of Ca2+ to the Gla domain and is affected minimally by interaction with thrombin. Hence, the zymogen protein C likely interacts with the thrombin-thrombomodulin complex through a rigid body association that produces a protease with essentially the same structural architecture. This scenario stands in contrast to an analogous reaction in the coagulation cascade where conversion of the zymogen prothrombin to the protease meizothrombin by the prothrombinase complex is linked to a large conformational transition of the entire protein. The presence of rigid epidermal growth factor domains in protein C as opposed to kringles in prothrombin likely accounts for the different conformational plasticity of the two zymogens. The new structural features reported here for protein C have general relevance to vitamin K-dependent clotting factors containing epidermal growth factor domains, such as factors VII, IX, and X.The antimalarial agents artemisinins inhibit cytomegalovirus (CMV) in vitro and in vivo, but their target(s) has been elusive. Using a biotin-labeled artemisinin, we identified the intermediate filament protein vimentin as an artemisinin target, validated by detailed biochemical and biological assays. We provide insights into the dynamic and unique modulation of vimentin, depending on the stage of human CMV (HCMV) replication. In vitro, HCMV entry and viral progeny are reduced in vimentin-deficient fibroblasts, compared with control cells. Similarly, mouse CMV (MCMV) replication in vimentin knockout mice is significantly reduced compared with controls in vivo, confirming the requirement of vimentin for establishment of infection. link2 Early after HCMV infection of human foreskin fibroblasts vimentin level is stable, but as infection proceeds, vimentin is destabilized, concurrent with its phosphorylation and virus-induced calpain activity. Intriguingly, in vimentin-overexpressing cells, HCMV infection is reduced compared with control cells. Binding of artesunate, an artemisinin monomer, to vimentin prevents virus-induced vimentin degradation, decreasing vimentin phosphorylation at Ser-55 and Ser-83 and resisting calpain digestion. In vimentin-deficient fibroblasts, the anti-HCMV activity of artesunate is reduced compared with controls. In summary, an intact and stable vimentin network is important for the initiation of HCMV replication but hinders its completion. Artesunate binding to vimentin early during infection stabilizes it and antagonizes subsequent HCMV-mediated vimentin destabilization, thus suppressing HCMV replication. Our target discovery should enable the identification of vimentin-binding sites and compound moieties for binding.

Supporting spiritual needs is a well-established aspect of palliative care, but no data exist regarding how physicians engage with patients and families around spirituality during care conferences in paediatric intensive care units (PICU).

To assess the frequency and characteristics of family and physician spiritual statements in PICU care conferences.

We performed qualitative analysis of 71 transcripts from PICU conferences, audio-recorded at an urban, quaternary medical centre. Transcripts were derived from a single-centre, cross-sectional, qualitative study.

We identified spiritual language in 46% (33/71) of PICU care conferences. Spiritual statements were divided relatively evenly between family member (51%, 67/131) and physician statements (49%, 64/131). Physician responses to families' spiritual statements were coded as supportive (46%, 31/67), deferred (30%, 20/67), indifferent (24%, 16/67) or exploratory (0/67).

In this single-centre PICU, spiritual statements were present 46% of the time during high stakes decision-making conferences, but there was little evidence of spiritual care best practices, such as offering chaplain support and performing open-ended spiritual assessments. PICU clinicians should expect spiritual statements in care conferences and be prepared to respond.

Denosumab, an antiresorptive medication, can be used to treat a number of cancer-related complications including hypercalcaemia, metastatic bone pain and to reduce fracture-events. We present a case of a hospice inpatient with profound and recurring hypocalcaemia following a single denosumab infusion which required repeated hospitalisation, for intravenous calcium, alongside a prolonged course of vitamin D and electrolyte replacement. The case highlights the risk of hypocalcaemia with denosumab use, together with the need to identify and treat vitamin D deficiency in both the prevention and management of such a complication.

Depression and vitamin D deficiency are common in patients with lung cancer and have prognostic implications in cancer settings. However, their relationship and concomitant survival implications have not been evaluated in patients with metastatic lung cancer specifically. We hypothesised that vitamin D deficiency would be associated with depression and inferior cancer-related survival in patients receiving therapies for stage IV lung cancer.

This was a cross-sectional analysis of vitamin D, depression and lung cancer characteristics. Vitamin D levels were stratified by level (no deficiency ≥30 units, mild deficiency 20 to 29 units and moderate-to-severe <20 units). Depression was measured by the Hospital Anxiety and Depression Scale-Depression (HADS-D). Survival estimations were made using Cox proportional hazard model and Kaplan-Meier analyses.

Vitamin D deficiency was evident in almost half of the sample (n=98) and was associated with significant depression (HADS-D ≥8) (χ

=4.35, p<0.001) even when controlling for age, sex and inflammation (β=-0.
