Our results suggest that argon preconditioning inhibited the PDCD4/PTEN pathway via miR-21, thereby inhibiting ROS oxidative stress and preventing MI/R injury.Global transcriptional regulators are prevalent in gram-positive pathogens. The transcriptional regulators of the Mga/AtxA family regulate target gene expression by directly binding to the promoter regions, that results in the coordinated expression of virulence factors. The spd_1587 gene of Streptococcus pneumoniae strain D39 encodes MgaSpn, which shares sequence similarity with global transcriptional regulators of the Mga/AtxA family. In this study, we demonstrated that MgaSpn regulates the biosynthesis of the capsule and phosphorylcholine, which play key roles in disease severity in S. pneumoniae infections. MgaSpn directly binds to the cps and lic1 promoters and affects the biosynthesis of the capsule and phosphorylcholine. MgaSpn binds to two specific sites on the promoter of cps, one of which contains the -35 box of the promoter, with high affinity. Consistently, low-molecular-weight capsule components were observed in the mgaSpn-null mutant strain. Moreover, we found that phosphorylcholine content was notably increased in the unencapsulated mgaSpn mutant strain. The mgaSpn null mutant caused more severe systemic disease than the parental strain D39. These findings indicate that the pneumococcal MgaSpn protein can inhibit capsule and phosphorylcholine production, thereby affecting the virulence of S. pneumoniae.Duck Tembusu virus (DTMUV), an emergent flavivirus, causes domestic waterfowls to suffer from severe egg-drop syndrome and fatal encephalitis, greatly threatens duck production globally. Like other mosquito-borne flaviviruses, the envelope (E) protein of all DTMUV strains was N-glycosylated at the amino acid position 154. Thus far, the biological roles of DTMUV E glycosylation have remained largely unexplored. Herein, we demonstrated the key roles of E glycosylation in the replication and pathogenicity of DTMUV in ducks by characterizing the reverse-genetics-derived DTMUV wild-type MC strain and MC bearing mutations (N154Q and N154I) that abolish the E glycosylation. Our data showed that the disruption of E glycosylation could substantially impair virus attachment, entry, and infectivity in DEFs and C6/36 cells. Notably, ducks inoculated intracerebrally with the wild-type virus exhibited severe disease onset. In contrast, those inoculated with mutant viruses were mildly affected as manifested by minimal weight loss, no mortality, lower viral loads in the various tissues, and reduced brain lesions. Attenuated phenotypes of the mutant viruses might be partly associated with lower inflammatory cytokines expression in the brains of infected ducks. Our study offers the first evidence that E glycosylation is vital for DTMUV replication, pathogenicity, and neurovirulence in vivo.While the benefits of human papillomavirus (HPV) vaccination relating to cervical cancer prevention have been widely documented, recent published evidence is suggestive of an impact on adverse pregnancy outcomes (APOs) in vaccinated mothers and their infants, including a reduction in rates of preterm births and small for gestational age infants. In this review, we examine this evidence and the possible mechanisms by which HPV vaccination may prevent these APOs. Large-scale studies linking HPV vaccination status with birth registries are needed to confirm these results. Potential confounding factors to consider in future analyses include other risk factors for APOs, and historical changes in both the management of cervical precancerous lesions and prevention of APOs. If confirmed, these additional benefits of HPV vaccination in reducing APO rates will be of global significance, due to the substantial health, social and economic costs associated with APOs, strengthening the case for worldwide HPV immunization.Young women are increasingly engaging with digital sexual media, yet discussion of female desire remains absent or is vilified. This paper examines young women's online sexual expression, as seen through the eyes of both young men and young women. Based on small friendship group interviews conducted with 106 12-16-year-old young women and men in Aotearoa New Zealand, I analysed perceptions of young women's sexual expression. Framed through patriarchal ideals and underpinned by competitive masculinity, young women's sexuality and opportunities for sexual expression were policed and regulated. Young women were expected to be passive yet digitally heterosexy, but not slutty. Perceptions of young women's sexual expression continue to be framed within silencing and absent pleasure discourses, which ultimately compromises both young men and women's development of sexual subjectivities.In this paper, we examine person-centred care through a Deleuzian posthuman lens with the aim of exploring what becomes possible when the concepts of both person and care are de-centred. We do so through a consideration of the sets of relations that produce 'the client' in health care contexts. Our analysis maps particular entangled material-semiotic forces producing 'M/michael', a young man with a diagnosis of Duchenne muscular dystrophy, within a rehabilitation clinic. Drawing on Deleuzian notions of assemblage, affect, and becoming we explore 'person-care' as an active production that dynamically enacts persons-as-clients through clinical arrangements. Persons are thus reconceptualised in terms of locally produced subject positions and their care relations, rather than pre-existing beings who can be 'centred' within health services. Paradoxically, by de-centring persons and care, we work to conjure ways to strengthen the aspirations of person centredness to humanise health practices. In doing so, we consider different possibilities for re-imagining clinical work and contribute to debates regarding how healthcare conceptualises and addresses disability, health, and wellbeing. We suggest that such posthuman analyses can open up new ways of understanding and re/forming healthcare.Differentiated thyroid cancer (DTC), such as papillary thyroid cancer, has a good prognosis after routine treatment. However, in the course of treatment, 5% to 20% of cases may dedifferentiate and can be transformed into dedifferentiated DTC (deDTC) or anaplastic thyroid cancer, leading to treatment failure. To date, several drugs have been used effectively for dedifferentiated thyroid cancer, whereas gene therapy may be a potential method. Literature reported that double suicide genes driven by human telomerase reverse transcriptase promoter (hTERTp) can specifically express in cancer cells and kill them. However, the weak activity of hTERTp limits its further research. To overcome this weakness, we constructed a novel chitosan nanocarrier containing double suicide genes driven by a 'gene switch' (a cascade of radiation enhancer E9 and a hTERTp). The vector was labeled with iodine-131 (131I). On one hand, E9 can significantly enhance the activity of hTERTp under the weak radiation of 131I, thereby increasing the expression of double suicide genes in deDTC cells. On the other hand, 131I also plays a certain killing role when it enters host cells. The proposed nanocarrier has good specificity for deDTC cells and thus deserves further study.ABSTRACTSyndemic theory hypothesises that observed clusters of diseases are the result of harmful social conditions. Critiques of syndemics present the theory as ambiguous and lacking empirical evidence. Syndemics are evidenced through qualitative assessments drawing on observations, epidemiology, and biomedical evidence to explain bio-bio and bio-social interactions. Quantitative syndemic studies commonly apply a summative approach, whereby the outcome is a result of the cumulative effect of the individual elements. More recently, quantitative studies apply analyses to assess mechanical interactions among conditions. This paper applies a synergy factor analysis to measure synergy - the enhancement of the effect of one element on the effect of the others. Data from the canonical quantitative syndemic analysis study was reanalysed to assess synergy among the elements of the SAVA syndemic (substance ab/use, violence, HIV/AIDS). Contrary to original study findings, which applied a summative approach, no synergy was measured. Synergistic interactions were confirmed among a subset of the study population; the effects of substance ab/use and violence on HIV were more than two times greater in White MSM than the predicted joint effect (SF = 2·32, 95%CI 1·02-5·11, p = 0·044), indicating synergy. Synergy factor analysis presents an accessible tool to measure syndemic interactions and facilitate timely global health responses.In Greece, given the precarious nature of the sex work industry, sex workers health and wellbeing is of concern. However, relevant research remains limited. This study examined whether sex workers' self-reported physical and mental health deteriorated across time points during the economic recession in Athens, Greece. The study focused on 13 areas where off-street and street-based sex work occurred. Cross-sectional data was collected from the same areas in 2009 (i.e. before the economic recession began) and in 2013 and 2019 (i.e. at time points during the recession). Self-reported physical and mental health decreased in 2013 and in 2019 compared to 2009. A positive association was found between the country's gross domestic product and sex workers' self-reported physical and mental health. The opposite was found for annual aggregate unemployment. The determinants of better self-reported physical and mental health were sex workers' economic condition, Greek nationality, off-street sex work, and registered sex work status. The opposite was found for more years' involvement in sex work and drug consumption. Findings indicate the need for more inclusive health strategies, especially during periods of economic downturn when sex workers' physical/mental health is likely to decline. This is the first study to investigate the association between economic recession and sex workers' self-reported physical and mental health.To investigate the potential role of GXYLT2 (glucoside xylosyltransferase 2) in gastric cancer (GC), the TCGA (The Cancer Genome Atlas) database and Gene Expression Omnibus (GEO) dataset were used to evaluate GXYLT2 mRNA expression, and the standardized mean difference and diagnostic value were comprehensively assessed. Survival analysis and univariate/multivariate cox regression analysis were performed to evaluate the prognostic value of GXYLT2 in GC patients. The correlation between GXYLT2 and tumor immune cells was identified by using the CIBERSORT algorithm. selleck chemicals The results showed that GXYLT2 expression level was significantly increased in GC tissues. GXYLT2 expression was significantly correlated with the grade, stage, and invasion depth of gastric cancer. Overall survival was reduced in the high GXYLT2 expression group. Univariate and multivariate Cox regression analyses showed that GXYLT2 was a reliable prognostic factor. GSEA showed that GXYLT2 might participate in the development of GC through tumor-related pathways.
