The downforce created by the flow separation from the ventral surface of the models at 0 deg angle of attack was another significant factor contributing to lift production. A number of cases showing large variations of aerodynamic performance included configurations close to the most probable posture of airborne flying snakes, suggesting that small postural variations could be used to control the glide trajectory.Visual motion detection is among the best understood neuronal computations. As extensively investigated in tethered flies, visual motion signals are assumed to be crucial to detect and counteract involuntary course deviations. During free flight, however, course changes are also signalled by other sensory systems. Therefore, it is as yet unclear to what extent motion vision contributes to course control. To address this question, we genetically rendered flies motion-blind by blocking their primary motion-sensitive neurons and quantified their free-flight performance. We found that such flies have difficulty maintaining a straight flight trajectory, much like unimpaired flies in the dark. By unilateral wing clipping, we generated an asymmetry in propulsive force and tested the ability of flies to compensate for this perturbation. While wild-type flies showed a remarkable level of compensation, motion-blind animals exhibited pronounced circling behaviour. Our results therefore directly confirm that motion vision is necessary to fly straight under realistic conditions.Rapid hardening is a process that quickly improves an animal's performance following exposure to potentially damaging stress. In this study of the Antarctic midge, Belgica antarctica (Diptera, Chironomidae), we examined how rapid hardening in response to dehydration (RDH) or cold (RCH) improves male pre- and post-copulatory function when the insects are subsequently subjected to a damaging cold exposure. Neither RDH nor RCH improved survival in response to lethal cold stress, but male activity and mating success following sublethal cold exposure were enhanced. Egg viability decreased following direct exposure of the mating males to sublethal cold but improved following RCH and RDH. Sublethal cold exposure reduced the expression of four accessory gland proteins, while expression remained high in males exposed to RCH. Though rapid hardening may be cryptic in males, this study shows that it can be revealed by pre- and post-copulatory interactions with females.Numerous serotypes which belong to the genus Enterovirus (EV) show variability in their virulence and clinical manifestations. They are also known to undergo changes caused by mutations and recombination during their circulation in the environment and the population. Various EV serotypes are prevalent in groundwater, wastewater and surface waters. Our previous studies showed that oral infection induces pancreatitis depending on specific conditions, such as gravidity, in an outbred murine model. Our aim in the present study was to further explore the pancreatic histopathology in an outbred mouse model following oral infection with clinical isolates from a patient who had aseptic meningitis and an isolate from a treated-sewage sample recovered from the residential area of the patient. The isolates were identified as coxsackievirus B4 (CVB4) in tissue culture. The CVB4 sewage-isolate induced pancreatitis after oral infection. In contrast, pancreatitis was absent following infection with the clinical isolates. Comparison of polyprotein sequences showed that the treated-sewage strains differed from the patient's isolates by 9 and 11 amino acids. Phorbol 12-myristate 13-acetate We conclude that the isolates of clinical and environmental origin differed in their pathogenic properties and showed genetic variation.

Metastasis to the brain is a major challenge with poor prognosis. The blood-brain barrier (BBB) is a significant impediment to effective treatment, being intact during the early stages of tumour development and heterogeneously permeable at later stages. Intravenous injection of tumour necrosis factor (TNF) selectively induces BBB permeabilisation at sites of brain micrometastasis, in a TNF type-1 receptor (TNFR1) dependent manner. Here, to enable clinical translation, we have developed a TNFR1-selective agonist variant of human TNF that induces BBB permeabilisation, whilst minimising potential toxicity.

A library of human TNF muteins (mutTNF) were generated and assessed for binding specificity to mouse and human TNFR1/2, endothelial permeabilising activity in vitro, potential immunogenicity and circulatory half-life. The permeabilising ability of the most promising variant was assessed in vivo in a model of brain metastasis.

The primary mutTNF variant showed similar affinity for human TNFR1 than wild-ty

Chronic musculoskeletal pain (CMP) outcomes are affected by numerous variables including the clinical conversation. When good therapeutic/working alliances are formed, congruent clinical conversations can lead to improved CMP outcomes. Identifying patient/provider attitudes, beliefs, and biases in CMP that can influence the clinical conversation, and thus clinical management decisions, is foundationally important.

The aims of this systematic review were to 1) summarize the evidence of the attitudes and beliefs of patients and healthcare providers (HCPs) involved in the clinical conversation of CMP; 2) examine if/how these perceptions impacted the process of care.

A systematic search of CINAHL, PubMed, Scopus, Sociology Database in ProQuest, and Web of Science used PRISMA guidelines. Included studies vulnerable adult populations with chronic pain. Study bias was examined using the Downs and Black tool.

Seven retrospective studies were included. HCPs demonstrated negative implicit biases toward minorititable care and the recalcitrant nature of CMP, particularly in vulnerable populations with limited healthcare choices.

Transgender adolescents use vape products (e.g., e-cigarettes) at higher rates than cisgender adolescents. Little is known about how these disparities differ from the intersectional perspective of both gender identity and race/ethnicity.

We examined disparities in past 30-day vaping frequency at the intersection of gender identity and race/ethnicity among adolescents participating in two pooled waves of the population-based California Healthy Kids Survey (N=953,445; 2017-19). Generalized linear mixed models included gender identity-by-race/ethnicity interactions and adjusted for potential confounders. Stratified models quantified relationships between gender identity and vaping within race/ethnicity strata and between race/ethnicity and vaping within gender identity strata.

Transgender adolescents of color were more likely to report a higher frequency of vaping than cisgender white adolescents. In models stratified by race/ethnicity, transgender adolescents evidenced greater odds of more frequent vapingnt vaping may differ by both gender identity and race/ethnicity-information needed to inform culturally-tailored prevention and control initiatives to decrease adolescent vaping disparities. Our analysis of data from a population-based adolescent health survey finds evidence of magnified disparities in vaping frequency among transgender adolescents of color.

Research finds that transgender adolescents use vape products at higher rates than their cisgender peers, however, little is known about how patterns of adolescent vaping may differ by both gender identity and race/ethnicity-information needed to inform culturally-tailored prevention and control initiatives to decrease adolescent vaping disparities. Our analysis of data from a population-based adolescent health survey finds evidence of magnified disparities in vaping frequency among transgender adolescents of color.Type 2 diabetes is associated with elevated levels of DNA damage, in particular micronuclei (MNi) which are formed by acentric chromosome fragments caused by double-stranded DNA breaks (DSBs), or whole chromosomes which fail to segregate during mitosis. We investigated if methylglyoxal (MGO), a reactive dicarbonyl known to be elevated in type 2 diabetes is capable of increasing chromosomal instability and DNA damage as measured by the cytokinesis block micronucleus cytome (CBMNcyt) assay in B-lymphoblastoid WIL2-NS cells and primary peripheral blood lymphocytes (PBL). We also investigated the level of various dicarbonyl stress biomarkers, including extracellular and intracellular MGO, protein and MGO modifications of DNA. WIL2-NS cells exposed to either MGO or a glyoxalase 1 inhibitor showed increases in MNi and nuclear buds, which were associated with an increase in intracellular MGO. DNA damage in the form of MNi and nucleoplasmic bridges were observed in primary PBL exposed to 10 µM MGO, suggesting low concentrations of MGO may be genotoxic. Furthermore, we showed, using fluorescent in situ hybridization, that the majority of MNi caused by MGO in WIL2-NS cells were caused by whole chromosome loss events, rather than DSBs. Our data suggest that MGO, a reactive metabolite elevated in type 2 diabetes and other pathologies, can affect genomic integrity by impairing chromosome segregation during mitosis.Root-pathogen interactions are an important factor influencing premature senescence in rice, however, few studies have addressed the underlying mechanism. In this study, when premature senescence significantly occurred in the OsVHA-A1 mutant (loss of tonoplast H +ATPase activity), the relative abundance of rhizospheric bacterial communities were similar between the mutant and its WT while the fungi in the rhizosphere of the OsVHA-A1 mutant significantly differed from the WT. link2 Furthermore, we found that one key fungal strain, named Gibberella intermedia, in the rhizospheric soil of the OsVHA-A1 mutant increased largely during the late growing phase, as compared to the WT and G. intermedia was shown to rapidly colonize the root of the OsVHA-A1 mutant resulting in severe ROS accumulation. But, the reverse was true in the case of the WT, indicating a much lower ROS level than those of the mutant when infected by G. intermedia. By using High Performance Liquid Chromatography (HPLC), we found that sugars in root exudates from the OsVHA-A1 mutant were different from sugars in root exudates from the WT. G. intermedia could efficiently use mannose and rhamnose in root exudates from the mutant better than other sugars. link3 Finally, antagonistic bacteria could be employed for limiting the proliferation of G. intermedia in rhizosphere, thereby alleviating the early senescent phenotypes of the OsVHA-A1 mutant rice and improving the grain yield.Regulatory T (Treg) cells that express the lineage-defining transcription factor Foxp3 play a pivotal role in establishing and maintaining immune and tissue homeostasis. Foxp3 serves as a highly connected "hub", interacting with numerous genomic sites and partner proteins, in the molecular network that orchestrates multiple facets of Treg cell differentiation and function. Treg cells are distributed throughout the body from lymphoid tissues to most non-lymphoid tissues, where they exert anti-inflammatory and protective functions appropriate for the tissue and immune environment. They are thus capable of adapting to diverse and changing environments by dynamically integrating extrinsic cues with the intrinsic molecular network. In this review, we discuss recent advances in our understanding of the cell-intrinsic and -extrinsic mechanisms underlying the adaptability of Treg cells and we propose a crucial role for the Foxp3-centered molecular network, which operates in a multimodal and adaptive manner in response to environmental signals.
