The simulated response of dimethylsulfide production in the Arctic Ocean to global warming

Sulfate aerosols (of both biogenic and anthropogenic origin) play a key role in the Earth’s radiation balance both directly through scattering and absorption of solar and terrestrial radiation, and indirectly by modifying cloud microphysical properties. However, the uncertainties associated with radiative forcing of climate due to aerosols substantially exceed those associated with the greenhouse gases. The major source of sulfate aerosols in the remote marine atmosphere is the biogenic compound dimethylsulfide (DMS), which is ubiquitous in the world’s oceans and is synthesized by plankton. Climate models point to significant future changes in sea-ice cover in the Arctic Ocean due to warming. This will have consequences for primary production and the sea-to-air flux of a number of biogenic compounds, including DMS. In this paper we discuss the impact of warming on the future production of DMS in the Arctic Ocean. A DMS production model has been calibrated to current climate conditions with satellite ocean colour data (SeaWiFS) using a genetic algorithm, an efficient non-derivative based optimization technique. We use the CSIRO Mk 2 climate model to force the DMS model under enhanced greenhouse climate conditions. We discuss the simulated change in DMS flux and its consequences for future aerosol production and the radiative budget of the Arctic. Significant decreases in sea-ice cover (by 18.5% annually and 61% in summer—autumn), increases in mean annual sea surface temperature of 1°C, and a decrease of mixed layer depth by 13% annually are predicted to result in annual DMS flux increases of over 80% by the time of equivalent CO2 tripling (2080). Estimates of the impact of this increase in DMS emissions suggest significant changes to summer aerosol concentrations and the radiative balance in the Arctic region.
Long‐Term Effects of Fine Particles on Mortality: Insights from 1984

I review an important study that Professor Evans published early in his career examining the role of cross‐sectional mortality studies in air pollution risk assessment. At a time when both risk assessment and particle effects on mortality were controversial, John's thoughtful analysis of the issues and data relevant to assessing long‐term mortality risks from airborne particles provides a comprehensive primer that is still relevant today. The paper includes a critical literature review, a meta‐analysis of published particle effect estimates, and a reanalysis of landmark cross‐sectional mortality data set. EPA criteria documents and related literature had largely discounted the cross‐sectional mortality findings on the basis of criticisms about exposure assessment and control for confounding. John's analysis reached a different conclusion, that is, “we are of the opinion that the cross‐sectional studies reflect a causal relationship between exposure to airborne particles and premature mortality. From our point of view it is as likely that parameters have been underestimated … as that they are overestimated due to confounding. ” The paper acknowledged the impossibility of precisely quantifying the long‐term mortality effect of particle air pollution, and that there is a need for further research utilizing alternative approaches. These conclusions foreshadow the emergence, a decade later, of the influential particulate matter (PM) mortality findings from the Harvard Six Cities and American Cancer Society cohort studies. I conclude by suggesting that well designed cross‐sectional studies could play a role in identifying exposure–response associations in resource‐poor settings where there is a paucity of local evidence to support air pollution regulations.
ERG and nestin: useful markers of immature vessels and novel prognostic markers in renal cell carcinoma.

OBJECTIVES Renal cell carcinoma (RCC) accounts for approximately 90% of all renal malignancy. Because a rich vasculature is an outstanding feature of RCC, information on the blood vessels of RCC might explain its tumor characteristics. Several researchers have noted the effects of tumor vessels on the clinicopathologic characteristics and prognosis of tumors; however, a clear association has not been established. We hypothesized that the immaturity of the neovasculature may be an important clinicopathologic characteristic forprognosis of RCC patients. ERG and nestin are new vascular markers that regulate vascular homeostasis and angiogenesis. Therefore, in the present study, we investigated how ERG and nestin were expressed with respect to tumor characteristics. MATERIALS AND METHODS IHC staining for ERG, nestin, CD31, and CD34 was performed for 217 renal tumors, including clear-cell RCC (ccRCC; n = 184), papillary RCC (pRCC; n = 14), chromophobe RCC (chRCC; n = 14), and oncocytoma (n = 5). RESULTS Vascular endothelial cells from normal kidney consistently showed strong nuclear expression of ERG and nestin. Conversely, a loss of ERG and nestin expression was observed in endothelial cells of some tumor blood vessels, which was associated with tumor progression. In particular, the loss of ERG expression was significantly associated with progression-free survival and overall survival (univariate analyses: P = 0.027 and P = 0.004, respectively; multivariate analyses: P = 0.030 and P = 0.046, respectively). CONCLUSION A loss of ERG and nestin expression is associated with tumor progression, and loss of ERG is a powerful prognostic marker for ccRCC.
Cancer‐related help‐seeking in cancer survivors living in regional and remote Australia

To measure rates of detection via screening, perceived self‐imposed delays in seeking medical attention, and support seeking in a sample of regional and remote people with a cancer diagnosis and to test whether an association exists between these behaviours and minimising problems and resignation, a need for self‐control and reliance and fatalism. Correlations and binary logistic regressions were conducted to test the associations between demographic characteristics, attitudes and behaviours.
Health-related quality of life of middle-aged and elderly people with hypertension: A cross-sectional survey from a rural area in China

Objective To evaluate health-related quality of life (HRQoL) of middle-aged and elderly people with hypertension in Enshi, China, and to explore the important correlates defining HRQoL. Methods From April through July 2018, a self-monitoring intervention program for hypertension control was implemented in a remote area of central China. Participants completed a cross-sectional survey which included demographic characteristics, the Health-related Quality of Life Survey, and the Pittsburgh Sleep Quality Index Survey. Univariate analysis was performed by analysis of variance, and multiple linear regression analysis was used to analyze the influencing factors of HRQoL in middle-aged and elderly hypertensive patients. In the multivariate analysis, the variables with P≤0.05 in the single factor analysis were combined with the professional significance to establish a multiple linear regression model. Results Information from 500 participants was available for analysis. Among them, the scores of PCS and MCS was 31.66 ± 9.50 and 41.38 ± 10.69, respectively. Multivariable regression analyses showed that higher education and sleep quality, and moderate physical activity (30 minutes for at least five days a week) had a positive influence on PCS scores. Higher monthly family income (3,000–5,000 ¥) and sleep quality, regular tea-drinking, having 30 minutes of moderate physical activity at least five days a week were positively associated with MCS scores. Conclusion The overall HRQoL for rural middle-aged and elderly hypertensive patients in Xuan’en county of Hubei province was poor. Effective relevant measures for the above factors were urgently needed to improve the quality of life for the elderly in rural areas. Awareness of these relevant factors could help health care professionals provide better supportive care.
Phenological Response in the Trophic Levels to Climate Change in Korea

The response of the phenological events of individual species to climate change is not isolated, but is connected through interaction with other species at the same or adjacent trophic level. Using long-term phenological data observed since 1976 in Korea, whose temperature has risen more steeply than the average global temperature, this study conducted phenological analysis (differ-ences in the phenology of groups, differences in phenological shifts due to climate change, differ-ences in phenological sensitivity to climate by groups, and the change of phenological day differ-ences among interacting groups). The phenological shift of the producer group (plants) was found to be negative in all researched species, which means that it blooms quickly over the years. The regression slope of consumers (primary consumers and secondary consumers) was generally posi-tive which means that the phenological events of these species tended to be later during the study period. The inter-regional deviation of phenological events was not large for any plant except for plum tree and Black locust. In addition, regional variations in high trophic levels of secondary consumers tended to be greater than that of producers and primary consumers. Among the studied species, plum was the most sensitive to temperature, and when the temperature rose by 1 °C, the flowering time of plum decreased by 7.20 days. As a result of checking the day differences in the phenological events of the interacting species, the phenological events of species were reversed, and butterflies have appeared earlier than plum, Korean forsythia, and Korean rosebay since 1990. Using long-term data from Korea, this study investigated differences in phenological reactions among trophic groups. There is a possibility of a phenological mismatch between trophic groups in the future if global warming continues due to differences in sensitivity to climate and phenological shifts between trophic levels.
The LACE Index: A Predictor of Mortality and Readmission in Patients With Acute Myocardial Infarction

ABSTRACT Introduction: Improving patient outcomes after acute myocardial infarction (AMI) may be facilitated by identifying patients at a high risk of adverse events before hospital discharge. We aimed to determine the accuracy of the LACE (Length of stay, Acuity, Comorbidities, Emergency presentations within prior 6 months) index score (a prediction tool) for predicting 30-day all-cause mortality and readmission rates (independently and combined) in South Australian AMI patients who had an angiogram. Methods: All consecutive AMI patients enrolled in the Coronary Angiogram Database of South Australia Registry at two major tertiary hospitals and discharged alive between July 2016 to June 2017. A LACE score was calculated for each patient, and receiver operating characteristic curve analysis was performed. Results: Analysis of registry patients found a 30-day unplanned readmission rate of 11.8% and mortality rate of 0.7%. Moreover, the LACE index was a moderate predictor (C-statistic = 0.62) of readmissions in this cohort, and a score ≥10 indicated moderate discriminatory capacity to predict 30-day readmissions. Conclusion: The LACE index shows moderate discriminatory capacity to predict 30-day readmissions and mortality. A cut-off score of nine to optimize sensitivity may assist clinicians in identifying patients at a high risk of adverse outcomes.
Prevalence of bacterial sexually transmitted infections and coinfection with HIV among men who have sex with men and transgender women in Tijuana, Mexico

We estimated the prevalence of syphilis and Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections, as well as human immunodeficiency virus (HIV) coinfection among cisgender men who have sex with cisgender men (MSM) and transgender women (TW) in Tijuana, Mexico. MSM and TW (N = 212) recruited via respondent-driven and venue-based sampling for HIV testing underwent sexually transmitted infection (STI) testing and completed interviewer-administered surveys in this study (2017–2018). Treponemal rapid tests were used at the point-of-care with positives undergoing confirmatory testing following the reverse syphilis-testing algorithm. Nucleic acid amplification testing of urine and swabs (rectal and pharyngeal) was used to detect CT/NG at three anatomic sites. Chi-squared tests were used to compare STI prevalence by HIV status. Sexually transmitted infection prevalence was 39.6% overall but higher for newly diagnosed HIV-positive (55.7%; N = 88) than HIV-negative (28.2%; N = 124) participants (p-value < 0.0001). Among newly diagnosed HIV-positive participants, the prevalence of syphilis was 35.2% (31/88), CT infection was 27.3% (24/88; nine urethral; 16 rectal; four pharyngeal), and NG infection was 26.1% (23/88; six urethral; 19 rectal; nine pharyngeal). Among HIV-negative participants, the prevalence of syphilis was 12.1% (15/124), CT infection was 13.7% (17/124; seven urethral; nine rectal; two pharyngeal), and NG infection was 9.7% (12/124; three urethral; seven rectal; seven pharyngeal). Over 60% of all CT (25/41) and NG (26/35) infections in the full sample occurred extragenitally in the absence of urethral infections, and over 80% of rectal (30/37) and pharyngeal (16/18) infections were asymptomatic. The high prevalence of syphilis, CT, and NG infections among MSM and TW in Tijuana suggests STI screening that includes extragenital tests, particularly at HIV diagnosis, may help curb HIV/STI transmission.
A chromosome‐level assembly of the harlequin ladybird Harmonia axyridis as a genomic resource to study beetle and invasion biology

The harlequin ladybird, Harmonia axyridis (Pallas), is a well‐known model organism for genetic studies and is also a well‐studied natural enemy used for pest control. It became an invasive species after being introduced to North America and Europe as a pest control agent. Though two genome assemblies for this insect have been previously reported, a high‐quality genome assembly at the chromosome level is still not available. Here, we obtained a new chromosome‐level genome assembly of H. axyridis by combining various sequencing technologies, namely Illumina short reads, PacBio long reads, 10X Genomics and Hi‐C. The chromosome‐level genome assembly is 423 Mb with a scaffold N50 of 45.92 Mb. Using Hi‐C data 1,897 scaffolds were anchored to eight chromosomes. A total of 730,068 repeat sequences were identified, making up 51.2% of the assembled genome. After masking these repeat sequences, we annotated 22,810 protein‐encoding genes. The X chromosome and Y‐linked scaffolds were also identified by resequencing male and female genomes and calculating the male to female coverage ratios. Two gene families associated with environmental adaptation, odorant receptor and cytochrome P450, were analysed and showed no obvious expansion in H. axyridis. We successfully constructed a putative biosynthesis pathway of harmonine, a defence compound in the haemolymph of H. axyridis, which is a key factor for H. axyridis strong immunity. The chromosome‐level genome assembly of H. axyridis is a helpful resource for studies of beetle biology and invasive biology.
The Novel Perspectives Opened by ST2 in the Pandemic: A Review of Its Role in the Diagnosis and Prognosis of Patients with Heart Failure and COVID-19

The increasing incidence of coronavirus disease 19 (COVID-19) and its polymorphic clinical manifestations due to local and systemic inflammation represent a high burden for many public health systems. Multiple evidence revealed the interdependence between the presence of cardiovascular comorbidities and a severe course of COVID-19, with heart failure (HF) being incriminated as an independent predictor of mortality. Suppression of tumorigenicity-2 ST2 has emerged as one of the most promising biomarkers in assessing the evolution and prognosis of patients with HF. The uniqueness of ST2 is determined by its structural particularities. Its transmembrane isoform exerts cardioprotective effects, while the soluble isoform (sST2), which is detectable in serum, is associated with myocardial fibrosis and poor outcome in patients with HF. Some recent data also suggested the potential role of sST2 as a marker of inflammation, while other studies highlighted it as a valuable prognostic factor in patients with COVID-19. In this review, we summarized the pathways by which sST2 is related to myocardial injury and its connection to the severity of inflammation in patients with COVID-19. Also, we reviewed possible perspectives of using it as a dual cardio-inflammatory biomarker, for both early diagnosis, risk stratification and prognosis assessment of patients with concomitant HF and COVID-19.
Modifications in the Topological Structure of EEG Functional Connectivity Networks during Listening Tonal and Atonal Concert Music in Musicians and Non-Musicians

The present work aims to demonstrate the hypothesis that atonal music modifies the topological structure of electroencephalographic (EEG) connectivity networks in relation to tonal music. To this, EEG monopolar records were taken in musicians and non-musicians while listening to tonal, atonal, and pink noise sound excerpts. EEG functional connectivities (FC) among channels assessed by a phase synchronization index previously thresholded using surrogate data test were computed. Sound effects, on the topological structure of graph-based networks assembled with the EEG-FCs at different frequency-bands, were analyzed throughout graph metric and network-based statistic (NBS). Local and global efficiency normalized (vs. random-network) measurements (NLE|NGE) assessing network information exchanges were able to discriminate both music styles irrespective of groups and frequency-bands. During tonal audition, NLE and NGE values in the beta-band network get close to that of a small-world network, while during atonal and even more during noise its structure moved away from small-world. These effects were attributed to the different timbre characteristics (sounds spectral centroid and entropy) and different musical structure. Results from networks topographic maps for strength and NLE of the nodes, and for FC subnets obtained from the NBS, allowed discriminating the musical styles and verifying the different strength, NLE, and FC of musicians compared to non-musicians.
Smart Textiles and Sensorized Garments for Physiological Monitoring: A Review of Available Solutions and Techniques

Several wearable devices for physiological and activity monitoring are found on the market, but most of them only allow spot measurements. However, the continuous detection of physiological parameters without any constriction in time or space would be useful in several fields such as healthcare, fitness, and work. This can be achieved with the application of textile technologies for sensorized garments, where the sensors are completely embedded in the fabric. The complete integration of sensors in the fabric leads to several manufacturing techniques that allow dealing with both the technological challenges entailed by the physiological parameters under investigation, and the basic requirements of a garment such as perspiration, washability, and comfort. This review is intended to provide a detailed description of the textile technologies in terms of materials and manufacturing processes employed in the production of sensorized fabrics. The focus is pointed at the technical challenges and the advanced solutions introduced with respect to conventional sensors for recording different physiological parameters, and some interesting textile implementations for the acquisition of biopotentials, respiratory parameters, temperature and sweat are proposed. In the last section, an overview of the main garments on the market is depicted, also exploring some relevant projects under development.
Activation of EGFR-Aurora A induces loss of primary cilia in oral squamous cell carcinoma.

OBJECTIVE Primary cilia, evolutionally conserved organelles involving multiple cell functions, are frequently lost in various cancers. However, little is known about the role of primary cilia in oral squamous cell carcinoma (OSCC). METHODS Immunofluorescence staining was applied to detect primary cilia in normal, oral leukoplakia (OLK) and OSCC tissues. Differentially expressed ciliary genes of OSCC were screened from the TCGA database. Immunohistochemical analysis was used for validating the correlation between the expression of interested proteins and primary cilia, and their regulatory effect on primary cilia was further proved in vitro and in vivo. RESULTS A significant decrease in cilia ratio was found in OLK, especially in OSCC. Multiple ciliary genes were abnormally expressed in OSCC and epidermal growth factor receptor (EGFR)-Aurora A signaling was chosen for further study. A parallel increase of EGFR-Aurora A was observed in OLK and OSCC tissues. Moreover, EGFR activation induced obvious cilia absorption by phosphorylating Aurora A. Besides, Aurora A silencing significantly restored ciliary expression and decreased tumor growth in vivo. CONCLUSIONS The abnormal activation of EGFR-Aurora A leads to the gradual loss of primary cilia in oral mucosa carcinogenesis. Primary cilia have the potential to be new biomarkers and therapeutic targets of oral cancer.
Evaluation of the Effectiveness of Using Platelet Rich Fibrin (PRF) With Bone Graft in the Reconstruction of Alveolar Cleft, A Prospective Study

Supplemental Digital Content is available in the text Clefts of the lip, alveolus, and palate are the most common congenital malformation of the orofacial region. Bone grafting of the alveolar cleft is necessary for rehabilitation of oral function. Platelet rich fibrin (PRF), an autologous fibrin matrix is a second-generation platelet concentrate that has a positive effect on bone healing. Aim of the Study: The aim of this prospective study is to investigate and evaluate the quality and quantity of the bone graft that mixed with PRF when used in reconstruction of alveolar cleft in terms of bone density and resorption rate of the bone graft. Materials and Methods: Sixteen patients with unilateral alveolar clefts were treated. The control group received bone grafts without PRF, while the remaining patients comprised the PRF group and received grafts with PRF. Postoperative bone graft density and rate of bone resorption were assessed by CBCT at 1 month and 6 months after surgery Results: Satisfactory bone bridging formation was observed in all patients and the mean of bone resorption in PRF group within 6 months after surgery lower than control group. The bone density of the PRF group was lower than that of the control group at 1st month, which later after 6 months increased to be more than the control group. Conclusions: Platelet rich fibrin that mixed with autogenous bone graft was significantly reduce postoperative bone resorption. PRF may provide a higher bone density in the long postoperative course.
