RESUMO
Aim: We hypothesized plasma sEH activity correlates with mortality in acute respiratory distress syndrome (ARDS) patients. Methods: Adult patients diagnosed with ARDS enrolled between 2017 and 2019 were included in this study. Results: A total of 337 adult patients met our inclusion criteria. Among them, 107 patients died within 28 days. The plasma sEH activity was higher in nonsurvivors relative to survivors. And a receiver operating characteristic curve with the area under the curve of 0.81 (95% confidence interval: 0.74-0.89) for the prediction of 28-day mortality was obtained. Its sensitivity and specificity were 72.5% and 74.6%, respectively. Conclusion: Elevated plasma sEH activity is associated with higher 28-day mortality in adult patients with ARDS.

RESUMO
Spine fractures represent a critical health concern with far-reaching implications for patient care and clinical decision-making. Accurate segmentation of spine fractures from medical images is a crucial task due to its location, shape, type, and severity. Addressing these challenges often requires the use of advanced machine learning and deep learning techniques. In this research, a novel multi-scale feature fusion deep learning model is proposed for the automated spine fracture segmentation using Computed Tomography (CT) to these challenges. The proposed model consists of six modules; Feature Fusion Module (FFM), Squeeze and Excitation (SEM), Atrous Spatial Pyramid Pooling (ASPP), Residual Convolution Block Attention Module (RCBAM), Residual Border Refinement Attention Block (RBRAB), and Local Position Residual Attention Block (LPRAB). These modules are used to apply multi-scale feature fusion, spatial feature extraction, channel-wise feature improvement, segmentation border results border refinement, and positional focus on the region of interest. After that, a decoder network is used to predict the fractured spine. The experimental results show that the proposed approach achieves better accuracy results in solving the above challenges and also performs well compared to the existing segmentation methods.
RESUMO
BRICS-Plus countries (Brazil, Russia, India, China, South Africa, and 30 other countries) is a group of 35 countries with emerging economies making up more than half of the world's population. We explored epidemiological trends of cardiovascular disease (CVD) mortality attributable to modifiable risk factors and its association with period and birth cohort effects and sociodemographic index (SDI) across BRICS-Plus countries by using joinpoint regression and age-period-cohort modeling from 1990 to 2019. Between 1990 and 2019, the all-ages CVD deaths increased by 85.2% (6.1 million to 11.3 million) across BRICS-Plus countries. The CVD age-standardized mortality rate attributable to dietary risks and smoking significantly decreased across BRICS-Plus countries, with some exceptions. However, four-fifths of BRICS-Plus countries observed a remarkable increasing trend of high body mass-index (BMI)-related CVD deaths, in particular, among younger adults (25-49 years). Early birth cohorts and individuals aged greater than 50 years showed a higher risk of CVD mortality. Both the China-ASEAN FTA and Mercosur regions stand out for their successful sociodemographic transition, with a significant reduction in CVD mortality over the study period. Singapore and Brazil achieved great progress in CVD mortality reduction and the other BRICS-Plus countries should follow their lead in adopting public health policies and initiatives into practice.

During the oocyte growth, maturation and zygote development, chromatin structure keeps changing to regulate different nuclear activities. Here, we reported the role of SMC2, a core component of condensin complex, in oocyte and embryo development. Oocyte-specific conditional knockout of SMC2 caused female infertility. In the absence of SMC2, oocyte meiotic maturation and ovulation occurred normally, but chromosome condensation showed defects and DNA damages were accumulated in oocytes. The pronuclei were abnormally organized and micronuclei were frequently observed in fertilized eggs, their activity was impaired, and embryo development was arrested at the one-cell stage, suggesting that maternal SMC2 is essential for embryonic development.

The high-flash heat generated by direct contact at asperity tips under high contact stress and shear significantly promotes the tribocatalytic reaction between a lubricating medium and a friction interface. Macroscale superlubricity can be achieved by using additives with good lubrication properties to promote the decomposition and transformation of a lubricating medium to form an ultralow shear interface during the friction process. This paper proposed a way to achieve self-adaptive oil-based macroscale superlubricity on different tribopairs, including steel-steel and steel-DLC (diamond-like carbon), which is based on the excellent lubricating performance of black phosphorus with active oxidation and the catalytic cleavage behavior of oil molecules on the surface of oBP. This work potentially expands the industrial application of superlubricity.
RESUMO
PURPOSE: To evaluate the safety and efficacy of a novel hyperthermic intravesical chemotherapy (HIVEC) device in combination with gemcitabine. MATERIALS AND METHODS: A pilot clinical trial was performed on patients with high-risk non-muscle invasive bladder cancer (NMIBC), who received HIVEC via the novel device (BR-PRG). Treatment regimen included eight weekly instillations of intravesical GEM (3 g in 150 mL normal saline [NS]) at a temperature of 45 °C for 60 min. Assessment of adverse events (AEs) was the primary objective of the trial. Disease recurrence and the thermal stability of GEM were also analyzed. RESULTS: A total of 116 HIVEC treatments were delivered. Fifteen and eighteen patients were included in the effectiveness and safety analysis, respectively. Median follow-up was 12 months; five patients experienced a disease recurrence. One-year cumulative incidence of recurrence was 23.8% in EORTC intermediate risk group and 37.5% in high-risk group. Ten patients experienced at least one AE, with the most common being acute urinary tract infection, followed by urinary tract pain, and hematuria. Two patients experienced acute cystitis (grade 3 AE) and instillations were postponed until full recovery. Other AEs were minor, and no systemic toxicity was observed. The contents of GEM in solution of 0.9% NS or NS mixed with artificial urine were stable at 25 °C, 37 °C, 43 °C, 45 °C, 47 °C and 50 °C for 2 h. CONCLUSION: GEM can be an ideal drug for use in HIVEC due to its good thermal stability. BR-PRG, combined with GEM was safe and effective in administering HIVEC.

Background: Unhealthy eating habits are a significant modifiable risk factor for cardiovascular diseases (CVDs); nevertheless, no evidence of their impact on the CVD burden has been reported in East Asian countries. We aimed to determine the trend and predict the future CVDs burden attributed to modifiable dietary risk factors in the East Asian countries (China, Japan, South Korea, and North Korea) and the world. Methods: The Global Burden of Disease (GBD) 2019 data were used to find the trend of CVDs [ischemic heart disease (IHD) and ischemic stroke (IS)] mortality- and disability-adjusted life-years (DALYs) attributed to dietary risk factors in the East Asian countries and the world (1990-2019) and its prediction from 2020 to 2030. We used the joinpoint regression model and the autoregressive integrated moving average (ARIMA) model for trend and future forecast, respectively. Results: From 1990 to 2019, regardless of sex, the age-standardized mortality rate (ASMR) and DALYs of IHD attributed to dietary risk factors significantly decreased in Japan, South Korea, and the world. However, the ASMR of IHD significantly increased in Chinese males and for both sexes in North Korea. The ASMR and DALYs of IHD and IS due to dietary risk factors were higher in males than in females in the world. From 2020 to 2030, the ASMR of IHD is predicted to increase in South Korean females and Japanese males. Globally, a diet low in whole grains was the top risk factor for the highest IHD mortality and DALYs in 2019, followed by a diet low in legumes and a diet high in sodium. A diet low in whole grains, a diet high in sodium, and a diet low in legumes were the leading risk factors for high IHD mortality in East Asian countries. Conclusion: The trend of IHD and IS burden due to dietary risk factors varies substantially across the East Asian countries compared to the trend of CVDs burden in the world. The study findings may help the public health policymakers to design proper strategies for improvement of the quality of life to combat the CVDs burden in the future for the East Asian countries.
RESUMO
BACKGROUND AND OBJECTIVES: Vestibular schwannoma (VS), the most common intercranial schwannoma, originates from the sheath of the vestibular nerve. The growth rate of VS varies greatly, with the tumor enlarging gradually, which can compress the peripheral nerve tissue and reveal corresponding symptoms. This study was aimed to elucidate the growth mechanism of VS by analyzing cellular changes at protein, messenger ribonucleic acid (mRNA), and other molecular levels. METHODS: We determined mRNA and protein levels of ß 2 -microglobulin (ß 2 -M) and nuclear factor κB (NF-κB) in tumors of different sizes using the real-time polymerase chain reaction and Western blotting, respectively. The relationship between these factors was verified in VS primary cells cultured in vitro, and the potential role of ß 2 -M and NF-κB in VS growth was elucidated. RESULTS: In the secretions of freshly isolated tumor tissue cultured for 72 h, the concentration of ß 2 -M was positively correlated with the tumor diameter. Furthermore, tumors with larger diameter showed higher expressions of ß 2 -M and NF-κB at protein and mRNA level. ß 2 -M treatment resulted in elevated protein expression of NF-κB and also its phosphorylated form in vitro. CONCLUSION: ß 2 -M may participate in VS growth by regulating NF-κB and act as a key regulatory molecule in VS tumor growth.

Multidrug-resistant pulmonary tuberculosis (MDR-TB) is a major health problem worldwide. The treatment for MDR-TB requires medications for a long duration (up to 20-24 months) with second-line drugs resulting in unfavorable outcomes. Nitroimidazoles are promising antimycobacterial agents known to inhibit both aerobic and anaerobic mycobacterial activity. Delamanid and pretomanid are two nitroimidazoles approved by the regulatory agencies for MDR-TB treatment. However, both agents possess unsatisfactory absorption and QTc prolongation. In our search for a safer nitroimidazole, we discovered JBD0131 (2). It exhibited excellent anti-mycobacterial activity against M. tuberculosis H37Rv in vitro and in vivo, improved PK and absorption, reduced QT prolongation potential of delamanid. JBD0131 is currently in clinical development in China for pulmonary tuberculosis (CTR20202308).

Background: A growing number of studies have suggested that transcranial magnetic stimulation (TMS) may represent a novel technique with both investigative and therapeutic potential for autism spectrum disorder (ASD). However, a full spectrum of the adverse effects (AEs) of TMS used in ASD has not been specifically and systematically evaluated. Objective: This systematic review and meta-analysis was to assess the prevalence of AEs related to TMS in ASD and to further explore the potentially related factors on the AEs. Methods: A systematic literature research of articles published before 31 December 2020 was conducted in the databases of PubMed, Embase, Cochrane Library, Ovid, PsycINFO, Chinese National Knowledge Infrastructure (CNKI), Chongqing VIP, and WANFANG DATA. AEs reported in the studies were carefully examined and synthesized to understand the safety and tolerability of TMS among ASD. Then, subgroup and sensitivity analyses were performed to examine the potentially related factors on the AEs. PROSPERO registration number: CRD42021239827. Results: Eleven studies were included in the meta-analysis. The pooled prevalence with 95% confidence interval (CI) of AEs was calculated (overall AEs: 25%, 95% CI 18-33%; headache: 10%, 95% CI 3-19%; facial discomfort: 15%, 95% CI 4-29%; irritability 21%, 95% CI 8-37%; pain at the application site: 6%, 95% CI 0-19%; headedness or dizziness: 8%, 95% CI 0-23%). All reported AEs were mild and transient with relatively few serious AEs and can be resolved after having a rest or medication. In addition, the following variables showed no significant change in overall prevalence of AEs: the purpose of using TMS, mean age of participants, whether the stimulation site was dorsolateral pre-frontal cortex (DLPFC), intensity of TMS, and the number of stimulation sessions. Conclusion: The overall prevalence of reported AEs of TMS among ASD was 25%. No identified ASD-specific risk factors for TMS-induced AEs were found. Further studies are needed to clarify the variation in the prevalence.

RESUMO
Neuroinflammation occurs early in Alzheimer's disease (AD). The initial stage of AD is related to glial dysfunction, which contributes to impairment of Aß clearance and disruption of synaptic connection. CEBPß, a member of the CCAAT-enhancer-binding protein (CEBP) family, modulates the expression of inflammation-associated genes, and its expression is elevated in brains undergoing degeneration and injured brains. However, the mechanism underlying CEBPß-mediated chronic inflammation in AD is unclear. In this study, we observed that increases in the levels of nuclear CEBPß facilitated the interaction of CEBPß with the NFκB p65 subunit, increasing the transcription of proinflammatory cytokines in the APP/PS1 mouse brain. Oral administration of nanocarrier-packaged carnosic acid (CA) reduced the aberrant activation of microglia and astrocytes and diminished mature IL-1ß, TNFα and IL-6 production in the APP/PS1 mouse brain. CA administration reduced ß-amyloid (Aß) deposition and ameliorated cognitive impairment in APP/PS1 mice. We observed that CA blocked the interaction of CEBPß with NFκB p65, and chromatin immunoprecipitation revealed that CA reduced the transcription of the NFκB target genes TNFα and IL-6. We confirmed that CA alleviated inflammatory mediator-induced neuronal degeneration and reduced Aß secretion by inhibiting the CEBPß-NFκB signalling pathway in vitro. Sulfobutyl ether-beta-cyclodextrin (SBEßCD) was used as the encapsulation agent for the CA-loaded nanocarrier to overcome the poor water solubility and enhance the brain bioavailability of CA. The CA nanoparticles (NPs) had no obvious toxicity. We demonstrated a feasible SBEßCD-based nanodelivery system targeting the brain. Our data provide experimental evidence that CA-loaded NPs are potential therapeutic agents for AD treatment.

MeHg, an environmental toxicant, is highly toxic to the central nervous system. Recent studies have reported that LMP is an important way in the lysosomal damage. However, the role and molecular mechanism of LMP in MeHg-induced neurotoxicity remain unknown. To study MeHg-induced LMP, we used 10µM MeHg to treat SH-SY5Y cells and 2µM MeHg to treat rat cerebral cortical neurons. Acridine orange (AO) staining and analysis of cathepsin B (CTSB) release were used to determine LMP. We found that MeHg reduced red AO fluorescence and induced CTSB release from lysosomes to the cytoplasm in a time-dependent manner. Moreover, pretreatment with the CTSB inhibitor alleviated cytotoxicity in neuronal cells. These results indicate MeHg induces LMP and subsequent CTSB-dependent cytotoxicity in neuronal cells. Bax is a pore-forming protein, which is involved in mitochondrial outer membrane permeabilization. Intriguingly, we demonstrated that MeHg induced Bax to translocate to lysosomes by using immunofluorescence and Western blot analysis of subcellular fractions. Furthermore, downregulating Bax expression suppressed MeHg-induced LMP. Bax subcellular localization is regulated by protein interaction with the cytoplasmic 14-3-3. Our previous study demonstrated that JNK participated in neurotoxicity through regulating protein interaction. In the current study, we showed that JNK dissociated Bax-14-3-3 complex to facilitate Bax lysosomal translocation. Finally, inhibition of the JNK/Bax pathway could alleviate MeHg-induced cytotoxicity in neuronal cells. The present study implies that inhibiting lysosomal damage (LMP)-related signaling might alleviate MeHg neurotoxicity.

Perilla (Perilla frutescens), a traditional medicinal and oilseed crop in Asia, contains extremely high levels of polyunsaturated α-linolenic acid (ALA) (up to 60.9%) in its seeds. ALA biosynthesis is a multistep process catalyzed by fatty acid desaturases (FADs), but the FAD gene family in perilla has not been systematically characterized. Here, we identified 42 PfFADs in the perilla genome and classified them into five subfamilies. Subfamily members of PfFADs had similar exon/intron structures, conserved domain sequences, subcellular localizations, and cis-regulatory elements in their promoter regions. PfFADs also possessed various expression patterns. PfFAD3.1 was highly expressed in the middle stage of seed development, whereas PfFAD7/8.3 and PfFAD7/8.5 were highly expressed in leaf and later stages of seed development, respectively. Phylogenetic analysis revealed that the evolutionary features coincided with the functionalization of different subfamilies of PUFA desaturase. Heterologous overexpression of PfFAD3.1 in Arabidopsis thaliana seeds increased ALA content by 17.68%-37.03%. These findings provided insights into the characteristics and functions of PfFAD genes in perilla.

In recent years, many rotational and integrated rice production systems coupled with several greenhouse gas (GHG) emissions mitigation practices have been developed and adopted for demand of low carbon production. However, there have been only few studies about comparisons on the balance between high production and mitigation of GHG emissions in different rice production systems. We therefore aimed to evaluate economic output and carbon footprint of different rice production systems, based on several long-term experiments conducted by our lab. CH4 and N2O emission were measured by the same static chamber/gas chromatogram measurement procedure in different rice production systems, including rice-fallow, rice-rapeseed, rice-wheat, double rice, and integrated rice-crayfish production system. Then, we applied the DeNitrification DeComposition model to simulate CH4 and N2O emission over different years under the same condition for comparison. Carbon footprint was calculated following the process-based life cycle assessment (PLCA) methodology. The economic benefit of rice production systems was assessed by cost-benefit analysis. According to the analysis, the double-rice production system exhibited the highest intensity of carbon footprint (ICF = 4.14 kg CO2-eq yuan-1), rain-fed treatment in the rice-rapeseed system had the lowest (ICF = 0.68 kg CO2-eq yuan-1). The intensity of carbon footprint in different treatments in the integrated rice-crayfish production system was around 0.8 kg CO2-eq yuan-1. Overall, the results of this case study suggest: (1) the proposed practices in different rice production systems are no straw returning (rice-fallow), no-tillage without straw returning (rice-wheat), rain-fed farming (rice-rapeseed), no insect and no inoculation (double rice), and feeding with straw returning (rice-crayfish); (2) rotational and integrated systems can achieve high net output with low carbon emission; (3) reducing the amount of nitrogenous fertilizer application is the most important and effective GHG mitigation practice for rotational systems.

BACKGROUND: HIIT has recently been widely used for health promotion in healthy people and patients with chronic diseases. Exercise can help SUD reduce drug cravings, enhance mental health and return to normal life. However, whether HIIT can bring better physical rehabilitation benefits to individuals with SUD than MICT is unclear. The study aimed to compare the effects of HIIT versus MICT on the physical fitness of individuals with SUD. METHODS: One hundred twenty individuals with amphetamine-type stimulant dependence voluntarily participated in this study. They were randomly assigned to the HIIT group and MICT group. Both groups received training three times a week. The intervention lasted from January 2019 to December 2019. Physical fitness was assessed at the baseline, 3 months, 6 months, 9 months and 12 months, including blood pressure (BP), vital capacity(VC), hand grip, push-up, sit-and-reach, one-leg standing with eyes closed and choice reaction time. The craving level was assessed using the Visual Analog Scale at baseline, 6 months and 12 months to see any change along with the improvement in physical fitness. Two-way repeated measures ANOVA was applied to analyse the differences in change by group (HIIT and MICT) and time (baseline, 3 months, 6 months, 9 months and 12 months). RESULTS: The within-group factor displayed significant changes in the HIIT and MICT groups in terms of systolic BP (F (4,336) = 12.799, P < 0.001,η2 = 0.204), diastolic BP (F(4,336) = 9.495, P < 0.001, η2 = 0.16), VC (F(4,336) = 18.121, P < 0.001, η2 = 0.177), hand grip (F(4,336) = 34.815, P < 0.001, η2 = 0.293), sit-and-reach (F(4,336) = 13.871, P < 0.001, η2 = 0.142), push-up (F(4,336) = 28.805, P < 0.001, η2 = 0.255), one-leg standing with eyes closed (F(4,336) = 14.495, P < 0.001, η2 = 0.156) and choice reaction time (F(4,336) = 20.603, P < 0.001, η2 = 0.197). The craving level decreased after 12 months of intervention in both groups (F(2,168) = 11.25, P < 0.001, η2 = 0.118), but no significant differences in physical fitness and craving level were found in between groups and the interactions of group × time. CONCLUSIONS: After 12 months of intervention, physical fitness improved while craving level decreased in the two groups. These findings suggest that both HIIT and MICT have positive effects on individuals with SUD in terms of physical fitness.

RESUMO
The traditional Chinese medicine Platycodon grandiflorum (PG) is often used for the treatment of a number of chronic inï¬ammatory diseases. In Chinese veterinary clinic, PG is always extracted by decoction and taken orally, however, the molecular mechanism of PG extract (PE) to reduce LPS-induced inflammation, especially acute lung injury (ALI) in vivo, are not known. Thus, we have studied the anti-inflammatory effects of PE on lipopolysaccharide (LPS)-induced acute lung injury via TLR4/NF-κBp65 pathway in rat. Sprague-Dawley rats were randomly divided into 4 groups: control group, LPS group, LPS±PE low dose group and LPS±PE high dose group. All rats were given corresponding PE solution or the same amount of normal saline by intragastric administration for 7 days. On the 7th day, 1 h after the last administration, 500 µg of LPS were introduced intratracheally to establish ALI rat model, and the same volume of normal saline was given to control group. The results showed that PE reduced the levels of LPS-induced pro-inflammatory mediators including IL-6, PGE2, and TNF-α, alleviated the lung injury histologically, and down-regulated LPS-induced mRNA and protein levels of TLR4/NF-κBp65 in lung tissue. This study demonstrated that PE has the anti-inflammatory effects on LPS-induced ALI in rats through TLR4/NF-κBp65 signaling pathway, indicating that PE is an effective suppressor for anti-inï¬ammatory activities.

BARMR1/FAM92A1 encodes a novel BAR domain protein, and is widely expressed during embryonic development and highly expressed in tumor cells. Mutation or deletion of BARMR1/FAM92A1 caused developmental disorder and the BARMR1/FAM92A1 overexpression in tumor cells is associated with poor prognosis. The subcellular location of BARMR1/FAM92A1 determined its biological functions by interacting with different proteins. When colocalized and interacted with CBY at the centrioles/basal bodies of primary cilia, BARMR1/FAM92A1 facilitate ciliogenesis, whilst binded to GAL1 in the nuclei, it promotes cell proliferation, migration, and malignancy of tumor cells.
