Abstract
BACKGROUND Teprotumumab was approved by the US Food and Drug Administration (FDA) for the treatment of thyroid eye disease in 2020. However, its adverse events (AEs) have not been investigated in real-world settings. AIM This study aimed to detect and evaluate AEs associated with teprotumumab in the real-world setting by conducting a pharmacovigilance analysis of the FDA Adverse Event Reporting System (FAERS) database. METHOD Reporting odds ratio (ROR) was used to detect risk signals from the data from January 2020 to March 2023 in the FAERS database. RESULTS A total of 3,707,269 cases were retrieved, of which 1542 were related to teprotumumab. The FAERS analysis identified 99 teprotumumab-related AE signals in 14 System Organ Classes (SOCs). The most frequent AEs were muscle spasms (n = 287), fatigue (n = 174), blood glucose increase (n = 121), alopecia (n = 120), nausea (n = 118), hyperacusis (n = 117), and headache (n = 117). The AEs with strongest signal strengths were autophony (ROR = 14,475.49), deafness permanent (ROR = 1853.35), gingival recession (ROR = 190.74), deafness neurosensory (ROR = 129.89), nail growth abnormal (ROR = 103.67), onychoclasis (ROR = 73.58), ear discomfort (ROR = 72.88), and deafness bilateral (ROR = 62.46). Eleven positive AE signals were found at the standardized MedDRA queries (SMQs) level, of which the top five SMQs were hyperglycemia/new-onset diabetes mellitus, hearing impairment, gastrointestinal nonspecific symptoms and therapeutic procedures, noninfectious diarrhea, and hypertension. Age significantly increased the risk of hearing impairment. CONCLUSION This study identified potential new and unexpected AE signals of teprotumumab. Our findings emphasize the importance of pharmacovigilance analysis in the real world to identify and manage AEs effectively, ultimately improving patient safety during teprotumumab treatment.

Abstract
OBJECTIVE To prepare GA-Emo micelles and investigate the feasibility of using GA as both a bifunctional drug and carrier. METHODS The preparation of GA-Emo micelles was accomplished via the thin-film dispersion method with GA as the carrier. Size distribution, entrapment efficiency, and drug loading were used to evaluate the characteristics of micelles. The absorption and transport properties of the micelles in Caco-2 cells were investigated, while their pharmacodynamics in mice were preliminarily studied. RESULTS The optimal formulation featured a GA/Emo in weight ratio of 2:1 and an encapsulation efficiency of 23.68%. The optimized GA/Emo was characterized as small uniform spheres with an average micellar size of 168.64 ± 5.69 nm, a polydispersity index of 0.17 ± 0.01, and an electrically negative surface (-35.33 ± 0.94 mV). Absorption and transport experiments with Caco-2 cells showed that the absorption of GA-Emo micelles in small intestines was mainly passive transport, amid their transport volume being significantly higher than that of Emo monomer. The intestinal wall thickness of the GAEmo micelles group was significantly lower than that of the Emo group, which meant that the colonic toxicity of the micelles was lower than unincorporated Emo. CONCLUSION The advantages of GA as a bifunctional micelle carrier in formulation characters, drug release, and toxicity attenuation provide a new idea for the application of the GA of natural medicine in drug delivery for toxicity reduction.

Abstract
The increased α-synuclein (α-syn)-dependent activation of CD4 T cells leads to the progressive loss of dopaminergic (DA) neurons in the substantia nigra (SN) in Parkinson's disease (PD). Astragaloside IV (AS-IV) protects DA neurons against neuroinflammation. The effects of AS-IV on CD4 T-cell-mediated immune responses in PD remain unknown. Rotenone (ROT) injected unilaterally into the substantia nigra pars compacta (SNc) of rats induced PD. AS-IV (20 mg/kg) was intraperitoneally injected once a day for 14 days. The limb hanging test and rotarod test were performed to evaluate the alteration of behavior at 4 and 6 weeks. Total gastrointestinal transit tests were performed at 4 weeks. Western blotting was used to detect the expression of proinflammatory cytokine proteins. Immunofluorescence staining was conducted to test the expression and localization of major histocompatibility complex class II (MHCII), cleaved caspase-1 and α-syn in astrocytes. Flow cytometry analysis, immunohistochemistry and immunofluorescence staining were used to measure the expression of CD4 T-cell subsets in the SN. The application of AS-IV protected against the loss of DA neurons and behavioral deficits in ROT-induced PD rat models. AS-IV administration inhibited the aggregation of α-syn in DA neurons and the expression of proinflammatory cytokines such as TNF-α, IL-18, IL-6 and IL-1β. AS-IV decreased the activation of CD4 T cells and three CD4 T-cell subsets: Tfh, Treg and Th1. AS-IV interrupted the ROT-induced interaction between astrocytes and CD4 T cells and the colocalization of MHCII and α-syn in astrocytes. AS-IV inhibited the expression of α-syn in astrocytes and the colocalization of α-syn and cleaved caspase-1 in astrocytes. AS-IV prevents the loss of DA neurons in PD by inhibiting the activation of α-syn-specific CD4 T cells, which is regulated by MHCII-mediated antigen presentation in astrocytes.

Abstract
Cellulase-mediated lignocellulosic biorefinery plays a crucial role in the production of high-value biofuels and chemicals, with enzymatic hydrolysis being an essential component. The advent of cellulase immobilization has revolutionized this process, significantly enhancing the efficiency, stability, and reusability of cellulase enzymes. This review offers a thorough analysis of the fundamental principles underlying immobilization, encompassing various immobilization approaches such as physical adsorption, covalent binding, entrapment, and cross-linking. Furthermore, it explores a diverse range of carrier materials, including inorganic, organic, and hybrid/composite materials. The review also focuses on emerging approaches like multi-enzyme co-immobilization, oriented immobilization, immobilized enzyme microreactors, and enzyme engineering for immobilization. Additionally, it delves into novel carrier technologies like 3D printing carriers, stimuli-responsive carriers, artificial cellulosomes, and biomimetic carriers. Moreover, the review addresses recent obstacles in cellulase immobilization, including molecular-level immobilization mechanism, diffusion limitations, loss of cellulase activity, cellulase leaching, and considerations of cost-effectiveness and scalability. The knowledge derived from this review is anticipated to catalyze the evolution of more efficient and sustainable biocatalytic systems for lignocellulosic biomass conversion, representing the current state-of-the-art in cellulase immobilization techniques.

Abstract
OBJECTIVES To assess whether coexisting fetal growth restriction (FGR) influences pregnancy latency among women with preterm pre-eclampsia undergoing expectant management. Secondary outcomes assessed were indication for delivery, mode of delivery and rate of serious adverse maternal and perinatal outcomes. METHODS We conducted a secondary analysis of the Pre-eclampsia Intervention (PIE) and the Pre-eclampsia Intervention 2 (PI2) trial data. These randomized controlled trials evaluated whether esomeprazole and metformin could prolong gestation of women diagnosed with pre-eclampsia between 26 and 32 weeks of gestation undergoing expectant management. Delivery indications were deteriorating maternal or fetal status, or reaching 34 weeks' gestation. FGR (defined by Delphi consensus) at the time of pre-eclampsia diagnosis was examined as a predictor of outcome. Only placebo data from PI2 were included, as the trial showed that metformin use was associated with prolonged gestation. All outcome data were collected prospectively from diagnosis of pre-eclampsia to 6 weeks after the expected due date. RESULTS Of the 202 women included, 92 (45.5%) had FGR at the time of pre-eclampsia diagnosis. Median pregnancy latency was 6.8 days in the FGR group and 15.3 days in the control group (difference 8.5 days; adjusted 0.49-fold change (95% CI, 0.33-0.74); P < 0.001). FGR pregnancies were less likely to reach 34 weeks' gestation (12.0% vs 30.9%; adjusted relative risk (aRR), 0.44 (95% CI, 0.23-0.83)) and more likely to be delivered for suspected fetal compromise (64.1% vs 36.4%; aRR, 1.84 (95% CI, 1.36-2.47)). More women with FGR underwent a prelabor emergency Cesarean section (66.3% vs 43.6%; aRR, 1.56 (95% CI, 1.20-2.03)) and were less likely to have a successful induction of labor (4.3% vs 14.5%; aRR, 0.32 (95% CI, 0.10-1.00)), compared to those without FGR. The rate of maternal complications did not differ significantly between the two groups. FGR was associated with a higher rate of infant death (14.1% vs 4.5%; aRR, 3.26 (95% CI, 1.08-9.81)) and need for intubation and mechanical ventilation (15.2% vs 5.5%; aRR, 2.97 (95% CI, 1.11-7.90)). CONCLUSION FGR is commonly present in women with early preterm pre-eclampsia and outcome is poorer. FGR is associated with shorter pregnancy latency, more emergency Cesarean deliveries, fewer successful inductions and increased rates of neonatal morbidity and mortality. © 2023 The Authors.

Abstract
Introduction The treatment with monosialotetrahexosylganglioside (GM1) improves the symptoms of Parkinson's disease (PD). The alteration of DNA methylation in the blood was examined to investigate epigenetic modification by GM1 treatment. Methods After a 28-day continuous intravenous infusion of GM1 (100mg), the motor and non-motor symptoms were evaluated by UPDRS III, Mini-mental state examination (MMSE) scores, FS-14, SCOPA-AUT, and PDQ-8. Moreover, blood samples were collected and PBMC was isolated. Genome-wide DNA methylation was performed by an 850K BeadChip. RNA levels and apoptosis were examined by RT-PCR and flow cytometry in rotenone-based cell models. The CREB5 plasmid was transfected by electroporation into SH-SY5Y cells. We also identified 235 methylation variable positions achieving genome-wide significance in 717558 differentially methylated positions (DMPs) (P = 0.0003) in comparison of pre-treatment with post-treatment measurements (statistical analysis paired-samples t-test). Results By searching the Gene Expression Omnibus (GEO) dataset and GWAS, 23 methylation variable positions were screened. Moreover, there are 7 hypomethylated methylation variable positions correlated with the scores of motor symptoms (UPDRS III scale). According to KEGG pathways enrichment analysis, the methylated genes CACNA1B (hypomethylated), CREB5 (hypermethylated), GNB4 (hypomethylated), and PPP2R5A (hypomethylated) were enriched in the dopaminergic synapse pathway. Pretreated with GM1 (80 μM) for 1 h, cell apoptosis and impaired neurite outgrowth were inhibited in rotenone-induced PD cell models. The RNA expression of CREB5 was increased in rotenone-treated SH-SY5Y cells. GM1 treatment decreased rotenone-induced CREB5 gene expression. The enhancement of CREB5 gene expression suppressed the protective role of GM1 in rotenone-induced cell apoptosis. Discussion The application of GM1 improves the motor and non-motor symptoms of PD associated with the decreased CREB5 expression and the hypermethylation of CREB5.

Abstract
We incorporate the fear effect and the maturation period of predators into a diffusive predator-prey model. Local and global asymptotic stability for constant steady states as well as uniform persistence of the solution are obtained. Under some conditions, we also exclude the existence of spatially nonhomogeneous steady states and the steady state bifurcation bifurcating from the positive constant steady state. Hopf bifurcation analysis is carried out by using the maturation period of predators as a bifurcation parameter, and we show that global Hopf branches are bounded. Finally, we conduct numerical simulations to explore interesting spatial-temporal patterns.

Abstract
In order to improve the separation process of affinity chromatography that has silica as the main carrier material, we sought to construct Lipid Rafts@CNBr-Sepharose 4B affinity chromatography model. We extracted the lipid rafts from U251 cells with a descaler method and sucrose density gradient centrifugation. Afterwards, it was discovered via immunofluorescence that the lipid rafts contain a large amount of tropomyosin-related kinase A (TrkA) protein. Also, agarose powder in the lyophilised state was pretreated, before the lipid rafts were coupled to the agarose gel in a coupling buffer of alkaline pH. CNBr-Sepharose 4B affinity gel packing was characterised using UV spectrophotometric, immunofluorescence and scanning electron microscopic techniques, wherein and the results showed that the lipid rafts were successfully coupled to the agarose gels. Three compounds were used to verify the specific sorption of Sepharose 4B and CNBr-Sepharose 4B, which showed no specific sorption on the materials. Of note, the prepared Lipid Rafts@CNBr-Sepharose 4B agarose gels packed with TrkA-rich target proteins could be successfully validated for the active drug gefitinib with high affinity sorption efficiency and eluted with good recovery and reproducibility. This study broadens the range of affinity chromatography carrier materials and provides a reference for research in active drug screening.

Abstract
BACKGROUND Postpartum depression (PPD) is a serious complication commonly seen in postnatal women. In this paper, an investigation was conducted to see if obstetric anesthesia clinic childbirth course combined with labor epidural analgesia (LEA) was associated with a decreased risk of PPD. METHODS Six hundred fifty-five nulliparous women were enrolled in this prospective cohort study. The parturients were divided into 4 groups, with Group C being the control group, Group AC received the obstetric anesthesia clinic childbirth course only, Group LEA received LEA only, and Group AC + LEA received both the obstetric anesthesia clinic childbirth course and LEA. Maternal and neonatal variables in the perinatal period were recorded. PPD at 6 weeks was assessed using the Chinese version of the Edinburgh Postpartum Depression Scale (EPDS), where a score ≥ 10 is the threshold for PPD. Multivariate logistic regression analysis was performed to assess the association between obstetric anesthesia clinic childbirth course combined with LEA and postpartum depression. RESULTS A total of 124 maternities had EPDS ≥10 points, the incidence of PPD was 18.9%。The incidence of PPD and EPDS scores were significantly lower in Group AC + LEA than in Group C (12.1% vs 26.8%, P < 0.05; 6 (5, 7) vs 7 (5, 11), P < 0.05). Received an anesthesia clinic childbirth course combined with LEA was associated with a decreased risk of PPD (OR 0.273, 95% CI, 0.100-0.743, P = 0.013). Multivariate logistic regression analysis identified 5 other independent factors for PPD, including maternal SAS score in the delivery room, W-DEQ score in the delivery room, living in a confinement center, EPDS score at 1st week postpartum and perinatal care satisfaction . CONCLUSIONS Received an obstetrics anesthesia clinic childbirth course combined with LEA for nulliparous women with a single term cephalic pregnancy was associated with a decreased risk of PPD at 6 weeks.

Abstract
Abstract
Study question
To determine the causal effect of in-vitro fertilisation (IVF) on primary school-age childhood developmental and educational outcomes, compared with outcomes following spontaneous conception.
Summary answer
The school-age developmental and educational outcomes for children conceived by IVF are equivalent to those of spontaneously conceived peers.
What is known already
More than 8 million children have been conceived globally with the assistance of in-vitro fertilization (IVF). Large cohort studies have suggested an increase in the frequency of congenital abnormalities, autism spectrum disorder, developmental-delay and intellectual disability in children conceived via IVF. Educational and cognitive outcomes following IVF conception have not yet been adequately established. Two large Scandinavian studies (Norrman et al 2018 and Wienecke et al 2020) found poorer educational outcomes in children born after IVF-conception.
Study design, size, duration
Causal inference methods (based on the potential outcomes approach) were used to analyse observation data in a way that emulates the results of a target randomised clinical trial. The study cohort comprised state-wide linked maternal and childhood administrative data from Victoria, Australia.
Participants/materials, setting, methods
The study included singleton infants conceived spontaneously or via IVF and born between 2005-2014. The exposure of interest was conception via IVF, with those born after spontaneous conception as the control group. Two separate measures of childhood outcome were examined: The Australian Early Developmental Consensus (AEDC), (age 4-6); and the National Assessment Program – Literacy and Numeracy (NAPLAN) at age 7-9. We combined inverse probability weighting with regression adjustment to estimate population average causal effects.
Main results and the role of chance
The final cohort included 412,713 children across the two outcome cohorts. Linked records were available for 4,697 IVF-conceived cases and 168,503 controls for AEDC outcome data, and 8,976 cases and 333,335 controls for NAPLAN data. The mothers of IVF-conceived children were older, more highly educated mothers, who lived in more socio-economic advantaged areas and were less likely to be from non-English speaking backgrounds. There was no causal effect of IVF-conception on the on the risk of developmental vulnerability at school-entry compared to spontaneously conceived children, as defined by AEDC metrics; with an adjusted risk difference of -0.3% (95% CI -3.7% to 3.1%) and an adjusted risk ratio of 0.97 (95% CI 0.77 to 1.25). At age 7-9 years, there was no causal effect of IVF-conception on the NAPLAN overall z-score, adjusted mean difference of 0.030 (95% CI -0.018 to 0.077) between IVF-conceived and spontaneously conceived children.
Given the use of observational data, there were missing data and inherent differences in the covariate profile of the exposure cohorts. Multiple imputation and doubly robust inverse probability weighting regression adjustment modelling was utilised to allow a causal interpretation of results.
Limitations, reasons for caution
Children who did not attend school due to severe disability were not included, possibly leading to selection bias. It is possible that unmeasured common cause confounders could have led to bias in estimating the average treatment effects.
Wider implications of the findings
This study, in contrast to previous evidence, suggests that conception via IVF does not affect early childhood developmental and educational outcomes. These findings provide important reassurance for current and prospective parents, and clinicians alike.

Abstract
Background Dexmedetomidine is a highly selective and efficient α2-adrenoceptor agonist with good antianxiety, analgesic, hypnotic, and sedative effects without causing respiratory depression. Aim To investigate the anesthetic effect of dexmedetomidine in clinical neurosurgery. Methods A total of 94 patients who received functional neurosurgical treatment in our hospital from March 2019 to October 2020 were selected and divided into the study and control groups. Routine anesthesia was adopted in the control group, while dexmedetomidine was used in the study group. Perioperative hemodynamic indicators such as mean arterial pressure, heart rate, and peripheral capillary oxygen saturation, cognitive function score, pain score VAS, stress response index level, and incidence of adverse reactions were compared between the two groups. Results Before surgery (T0), no significant differences in MAP, HR, and SpO2 were observed between the two groups. However, at the beginning of the operation (T1), 30 min after the operation (T2), and immediately after the operation (T3), these indicators in the study group were significantly higher than in the control group. The postoperative MMSE of the study group 3 d later was significantly higher than that of the control group. The VAS scores after the operation of the study group were lower than those of the control group. The serum cortisol (COR) and aldosterone (ALD) levels in the study group were not significantly different from those in the control group before surgery. The levels of each index in the two groups were higher than those before and 24 h after surgery. The incidence rate of adverse reactions in the study group was lower. Conclusion The application of dexmedetomidine in clinical functional neurosurgery is safe and can maintain hemodynamic stability and reduce the degree of stress response, cognitive impairment, and pain caused by invasive surgery.

Abstract
Toxic heavy metal ions, valuable noble metal ions and organic dyes are significant concerns in wastewater treatment. In this work, MoO3 nanobelts (MoO3 NBs) prepared by solvothermal method and MoS2 nanoarrays (MoS2 NAs) constructed using MoO3 NBs precursor were proposed to effectively remove heavy/noble metal ions and organic dyes, such as Pb(II), Au(III) and Methylene Blue (MB). The two adsorbents exhibited the excellent adsorption capacity towards Pb(II), Au(III) and MB. The maximum removal capacity of Pb(II) and MB on MoO3 NBs was 684.93 mg/g and 1408 mg/g, respectively, whereas that of Au(III) and MB on MoS2 NAs was 1280.2 mg/g and 768 mg/g, respectively. Furthermore, the thermodynamic parameters were calculated from the temperature-dependent curves, suggesting that the removal of Pb(II) and Au(III) on both adsorbents was spontaneous and endothermic. The new adsorbents introduced here were high adsorption activity, ease of fabrication, high scalability, good chemical stability, great repeatability and abundant and cheap supply, which were highly attractive for wastewater treatment.

Abstract
Induced hypothermia has been broadly applied in neurological intensive care unit (NICU). Meanwhile, accidental hypothermia is also a threatening condition in daily life. It is meaningful to investigate the influences of temperature change on the cerebral blood flow (CBF). In the present study, temporal laser speckle image contrast analysis (tLASCA) was implemented to study the relative CBF change in cerebral artery, vein and capillary level under mild (35$\circ$C) and moderate (32$\circ$C) hypothermia. Twelve male Sprague-Dawley rats (300±50g) were anesthetized with sodium pentobarbital and randomly assigned to mild and moderate hypothermia groups (n=9 each). Laser speckle imaging trials were acquired from baseline (37$\circ$C), hypothermia (35$\circ$C or 32$\circ$C) and post-rewarming (37$\circ$C) phases. In the mild group, mean CBF in different vessels all increased throughout the hypothermic and post-rewarming phases. On the contrary, mean CBF reduced by 10% to 20% at 32$\circ$C and returned to ~95% of the baseline level during the post-rewarming session in the moderate group. Besides, in the moderate group, a CBF rebound in vein was found in the post-rewarming phase. Our results suggested that the CBF changed differently between mild and moderate hypothermia, which may worth for further study in clinical. And we demonstrated LSI as a promising method to achieve high spatiotemporal resolution CBF change with minimal invasion.

Abstract
Climate change affects human health; however, there have been no large-scale, systematic efforts to quantify the heat-related human health impacts that have already occurred due to climate change. Here, we use empirical data from 732 locations in 43 countries to estimate the mortality burdens associated with the additional heat exposure that has resulted from recent human-induced warming, during the period 1991-2018. Across all study countries, we find that 37.0% (range 20.5-76.3%) of warm-season heat-related deaths can be attributed to anthropogenic climate change and that increased mortality is evident on every continent. Burdens varied geographically but were of the order of dozens to hundreds of deaths per year in many locations. Our findings support the urgent need for more ambitious mitigation and adaptation strategies to minimize the public health impacts of climate change.

Abstract
Objectives: This study aimed to evaluate the level and factors affecting the perioperative exercise intention in China. Design: This study was a cross-sectional survey in Southwest China. Methods: Four hundred and ninety nine participants were randomly sampled in eight medical centers from November 23, 2020 to November 27, 2020. The survey included sociodemographic information and a 24-item modified questionnaire, which aimed to evaluate the attitude toward daily exercise, perception of perioperative exercise, social support and the perioperative exercise intention. A multivariable linear regression model was used to evaluate the effect of different items on the patients' intention for perioperative exercise. Results: A total of 523 responses (95.09%) were collected and 499 (95.41%) were analyzed. The level of exercise intention of the patients during the perioperative period was: 14.83% planned to exercise every day in the hospital, 21.04% planned to exercise every other day, and 35.87% planned to exercise every week. Intensity of daily exercise (P = 0.016), positive attitude of daily exercise (P < 0.001), positive attitude of perioperative exercise (P < 0.001) and social support (P < 0.001) were positively associated with the intention for perioperative exercise. Female (P = 0.012), non-tertiary center (P = 0.011), and preoperative anxiety (P = 0.023) was negatively associated with it. Conclusions: The intention for perioperative exercise was low in Southwest China. The authors aimed to relieve preoperative anxiety, promote the education of perioperative exercise, design perioperative exercise programs, and provide more social support from medical staff and family for inpatients undergoing elective surgery.

Abstract
In the past few years, two-dimensional (2D) nanomaterials have emerged great potential for the removal of valuable metals and the capture of polluted-heavy metals. Herein, hierarchically flower-like microcrystals with 2D WS2 nanosheets (F-WS2 MCs) were prepared by one-pot hydrothermal synthesis strategy and its adsorption performances for precious metals were systematically assessed. The excellent adsorption efficiencies of ∼86.8%, ∼27.6%, and ∼94.1% towards Ag (I), Pd (II), and Au (III) respectively were achieved within 120 min, and the adsorption curves were in good agreement with a pseudo-second-order kinetic model showing a fast uptake rate at the optimum pH values (1.30 for Au (III), 1.43 for Ag (I), and 3.20 for Pd (II)). The adsorption isotherm followed well in the Langmuir model with the maximum removal capacities (qmax) of 186.2 mg g-1 for Ag (I), 67.29 mg g-1 for Pd (II), and 1340.6 mg g-1 for Au (III), respectively. Furthermore, for recycling purposes, the relevant desorption solution was investigated with different ratios of monobasic acid and thiourea, suggesting the best desorption efficiency of 93.03%, 88.08%, and 85.34% for Ag (I), Pd (II), and Au (III), respectively. By characterizing the crystalline phase, and micromorphology element mapping of F-WS2 MCs before and after adsorption, the strong affinity and significant adsorption-reduction were indicated to dominate the adsorption process. Therefore, this work broadens the application range of WS2 microcrystals, providing an alternative material for capturing precious metals and wastewater treatment applications.

Abstract
Background:Toll-Like Receptors (TLR) and Interleukin-1 Receptors (IL-1R) play a critical role in the innate immune response as microbial and tissue damage sensors, providing a bridge between the innate and adaptive immunity. Interleukin receptor associated kinases (IRAK) 1 and 4 are serine/threonine kinases that are essential for signaling downstream of most TLRs and IL-1Rs and the resulting production of pro-inflammatory cytokines. Suppression of TLR and IL-1R signaling through inhibition of IRAK1/4 kinases is a promising therapeutic approach for the treatment of inflammatory and autoimmune diseases. We have identified a potent and selective IRAK1/4 inhibitor (R835) that showed dose-dependent inhibition of lipopolysaccharide (LPS, a TLR4 agonist), and IL-1β induced serum cytokines in mice. R835 prevented disease onset and progression in multiple rodent models of inflammatory diseases, including arthritis and lupus models.Objectives:The aim of this FIH study was to characterize the safety, pharmacokinetics (PK) and pharmacodynamics (PD) of R835 after single or multiple dose oral administrations.Methods:This study was a randomized, placebo-controlled, double-blind Phase 1 study in healthy subjects in three parts: single ascending doses (20 mg-1920 mg, Part A) with food effect in a separate cohort (480 mg), multiple ascending doses (120 mg and 960 mg, BID, Part B) with a caffeine interaction (960 mg cohort), and an intravenous LPS challenge test at 240 mg oral dose of R835 (Part C).Results:Single doses of up to 480 mg R835 in organic solution, single doses of up to 1920 mg R835 as capsule, multiple doses of 120 mg R835 Q12H (organic solution), and 960 mg R835 Q12H (capsule) were safe and well tolerated. All R835 related adverse events (AEs) were mild in intensity and reversible, and mostly associated with the higher doses of R835 in the organic solution. The most common AEs were headache and gastrointestinal disturbance. The PK of R835 was linear and dose proportional in exposure over the dose range studied. A nominal level of accumulation in plasma achieved rapidly upon repeated BID administrations with steady-state essentially attained in 2 days. A high-fat meal with the capsule formulation resulted in slow rate of absorption but had no effect on the extent of absorption. There was no effect of R835 on metabolism of caffeine (P450 CYP1A2 prototype substrate). In the LPS challenge test, R835 profoundly inhibited the acute release of cytokines, including TNF-α, IL-6, IL-8, MIP1α and MIP1β, but had no impact on CRP release.Conclusion:R835 was well tolerated after single or multiple dose administrations. The most common AEs were headache and gastrointestinal disturbance. For both of the formulations tested, the PK of R835 was linear and exposure was dose proportional with rapid steady-state attainment following BID administration. There was no drug-drug interaction by use of caffeine as the protype substrate. R835 inhibited the LPS induced release of cytokines in the serum, including TNF-α, IL-6, IL-8, MIP1α and MIP1β, mirroring preclinical data in mice. The desirable PK and safety profile combined with proof of mechanism, as demonstrated by inhibition of cytokine release, support progression of R835 into Phase II clinical development as an agent for the treatment of inflammatory and autoimmune diseases.Disclosure of Interests: :Lucy Yan Shareholder of: Amgen, Rigel, Employee of: Amgen, Rigel, Sandra Tong Shareholder of: Rigel, Employee of: Rigel, Anthony Absalom: None declared, Izaak den Daas: None declared, Gary Park Shareholder of: Rigel Pharmaceuticals, Employee of: Rigel Pharmaceuticals, Vanessa Taylor Shareholder of: Rigel Pharmaceuticals, Employee of: Rigel Pharmaceuticals, Donna Chow Shareholder of: Rigel, Employee of: Rigel, Meng Lee Shareholder of: Rigel, Employee of: Rigel, Hanzhe Zheng Shareholder of: Rigel, Employee of: Rigel, Andrew Chow Shareholder of: Rigel, Employee of: Rigel

Abstract
OBJECTIVES Pneumonia is a significant contributor to mortality and morbidity in children aged <5 years, and it is also one of the leading causes of hospitalisation for children in this age group. This study assessed the association between climate variability, patient characteristics (i.e. age, sex, weight, parental education, socio-economic status) and length of stay (LOS) in hospital for childhood pneumonia and its economic impact on rural Bangladesh. STUDY DESIGN An ecological study design was used. METHODS Data on daily hospitalisation for pneumonia in children aged <5 years (including patient characteristics) and daily climate data (temperature and relative humidity) between 1st January 2012 and 31st December 2016 were obtained from the Matlab Hospital (the International Centre for Diarrhoeal Disease Research, Bangladesh) and the Bangladesh Meteorological Department, respectively. A generalised linear model with Poisson link was used to quantify the association between climate factors, patient characteristics and LOS in hospital. RESULTS The study showed that average temperature, temperature variation and humidity variation were positively associated with the LOS in hospital for pneumonia. A 1°C rise in average temperature and temperature variation during hospital stay increased the LOS in hospital by 1% (relative risk [RR]: 1.010, 95% confidence interval [CI]: 1.001-1.018) and 9.3% (RR: 1.093, 95% CI: 1.051-1.138), respectively. A 1% increase in humidity variation increased the LOS in hospital for pneumonia by 2.2% (RR: 1.022, 95% CI: 1.004-1.039). In terms of economic impact, for every 1° C temperature variation during the period of hospital stay, there is an addition of 0.81 USD/day/patient as a result of direct costs and 1.8 USD/day/patient for total costs. Annually, this results in an additional 443 USD for direct and 985 USD for total costs. CONCLUSIONS Climate variation appears to significantly contribute to the LOS in hospital for childhood pneumonia. These findings may help policymakers to develop effective disease management and prevention strategies.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Trillium tschonoskii Maxim, a perennial herb of the Trilliaceae, has been widely used to treat inflammation, hypertension and cancer. We investigated Paris saponin VII's (PS VII), isolated from Trillium tschonoskii Maxim, function in mediating autophagy and apoptosis in NSCLC cells. MATERIALS AND METHODS We treated various NSCLC cells with different concentrations of PS Ⅶ and then measure the cell apoptosis by using flow cytometry assays and western blot. Autophagy were investigated by using western blot, transmission electron microscopy and immunofluorescence analysis. We also use a xenograft model of nude mice to measure the effect of PS Ⅶ in vivo. RESULTS Treatment with PS Ⅶ significantly inhibit NSCLC cell growth, especially for A549 (IC50 = 1.53 μM). Moreover, PS VII induces caspase-dependent apoptosis and autophagy through AMPK-ULK1 pathway. After blocking autophagy by 3-methyladenine (3-MA), PS VII induced cell death was significantly increased. In vivo, the co-treatment with PS VII and 3-MA dramatically inhibited A549 tumor growth in immune deficient mice and has similar inhibition rates as cisplatin group. CONCLUSION Our results suggest that a combination of PS VII and autophagy inhibitor may be a potential anticancer strategy in the NSCLC therapy.

Abstract
OBJECTIVE Fetal growth restriction (FGR) is a major risk factor for stillbirth and most commonly arises from uteroplacental insufficiency. Despite clinical examination and third-trimester fetal biometry, cases of FGR often remain undetected antenatally. Placental insufficiency is known to be associated with altered blood flow resistance in maternal, placental and fetal vessels. The aim of this study was to evaluate the performance of individual and combined Doppler blood flow resistance measurements in the prediction of term small-for-gestational age and FGR. METHODS This was a prospective study of 347 nulliparous women with a singleton pregnancy at 36 weeks' gestation in which fetal growth and Doppler measurements were obtained. Pulsatility indices (PI) of the uterine arteries (UtA), umbilical artery (UA) and fetal vessels were analyzed, individually and in combination, for prediction of birth weight < 10th , < 5th and < 3rd centiles. Doppler values were converted into centiles or multiples of the median (MoM) for gestational age. The sensitivities, positive and negative predictive values and odds ratios (OR) of the Doppler parameters for these birth weights at ∼ 90% specificity were assessed. Additionally, the correlations between Doppler measurements and other measures of placental insufficiency, namely fetal growth velocity and neonatal body fat measures, were analyzed. RESULTS The Doppler combination most strongly associated with placental insufficiency was a newly generated parameter, which we have named the cerebral-placental-uterine ratio (CPUR). CPUR is the cerebroplacental ratio (CPR) (middle cerebral artery PI/UA-PI) divided by mean UtA-PI. CPUR MoM detected FGR better than did mean UtA-PI MoM or CPR MoM alone. At ∼ 90% specificity, low CPUR MoM had sensitivities of 50% for birth weight < 10th centile, 68% for < 5th centile and 89% for < 3rd centile. The respective sensitivities of low CPR MoM were 26%, 37% and 44% and those of high UtA-PI MoM were 34%, 47% and 67%. Low CPUR MoM was associated with birth weight < 10th centile with an OR of 9.1, < 5th centile with an OR of 17.3 and < 3rd centile with an OR of 57.0 (P < 0.0001 for all). CPUR MoM was also correlated most strongly with fetal growth velocity and neonatal body fat measures, as compared with CPR MoM or UtA-PI MoM alone. CONCLUSIONS In this cohort, a novel Doppler variable combination, the CPUR (CPR/UtA-PI), had the strongest association with indicators of placental insufficiency. CPUR detected more cases of FGR than did any other Doppler parameter measured. If these results are replicated independently, this new parameter may lead to better identification of fetuses at increased risk of stillbirth that may benefit from obstetric intervention.

Abstract
Global environmental changes, driven by the consequences of human activities and population growth, are altering our planet in ways that pose current threats to human health, with the magnitude of these threats projected to increase over coming decades if additional, proactive actions are not taken. Global changes, unprecedented in their geospatial and temporal scales, include climate change, marine pollution, ozone layer depletion, soil degradation, and urbanization. Climate change is the best studied. The health risks of a changing climate will become increasingly urgent as climate change affects the quantity and quality of food and water, increases air pollution, alters the distribution of vectors/pathogens and disease transmission dynamics, and reduces eco-physical buffering against extreme weather and climate events. Health systems urgently need to be improved to effectively address these emerging challenges. This paper provides an overview of the health consequences of climate change, and discusses how health risks can be minimized and avoided via mitigation and adaptation pathways.

Abstract
The therapeutic efficiency of allogenic/intrinsic neural stem cells (NSCs) after spinal cord injury is severely compromised because the hostile niche at the lesion site incurs massive astroglial but not neuronal differentiation of NSCs. Although many attempts are made to reconstruct a permissive niche for nerve regeneration, solely using a living cell material to build an all-in-one, multifunctional, permissive niche for promoting neuronal while inhibiting astroglial differentiation of NSCs is not reported. Here, ectomesenchymal stem cells (EMSCs) are reported to serve as a living, smart material that creates a permissive, all-in-one niche which provides neurotrophic factors, extracellular matrix molecules, cell-cell contact, and favorable substrate stiffness for directing NSC differentiation. Interestingly, in this all-in-one niche, a corresponding all-in-one signal-sensing platform is assembled through recruiting various niche signaling molecules into lipid rafts for promoting neuronal differentiation of NSCs, and meanwhile, inhibiting astrocyte overproliferation through the connexin43/YAP/14-3-3θ pathway. In vivo studies confirm that EMSCs can promote intrinsic NSC neuronal differentiation and domesticating astrocyte behaviors for nerve regeneration. Collectively, this study represents an all-in-one niche created by a single-cell material-EMSCs for directing NSC differentiation.

Abstract
Since the emergence of Middle East respiratory syndrome coronavirus (MERS-CoV) in 2012, there have been a number of clusters of human-to-human transmission. These cases of human-to-human transmission involve close contact and have occurred primarily in healthcare settings, and they are suspected to result from repeated zoonotic introductions. In this study, we sequenced whole MERS-CoV genomes directly from respiratory samples collected from 23 confirmed MERS cases in the United Arab Emirates (UAE). These samples included cases from three nosocomial and three household clusters. The sequences were analysed for changes and relatedness with regard to the collected epidemiological data and other available MERS-CoV genomic data. Sequence analysis supports the epidemiological data within the clusters, and further, suggests that these clusters emerged independently. To understand how and when these clusters emerged, respiratory samples were taken from dromedary camels, a known host of MERS-CoV, in the same geographic regions as the human clusters. Middle East respiratory syndrome coronavirus genomes from six virus-positive animals were sequenced, and these genomes were nearly identical to those found in human patients from corresponding regions. These data demonstrate a genetic link for each of these clusters to a camel and support the hypothesis that human MERS-CoV diversity results from multiple zoonotic introductions.

Abstract
The coupling of cerebral blood flow (CBF) to neuronal activation, referred to as activation flow coupling (AFC), has been a fundamental brain physiology property. The stimulus-evoked CBF response was usually considered as a surrogate marker for neuronal activity in AFC studies. The selection of appropriate stimulation parameters, e.g., current amplitude and pulse width, is of great importance yet the effect of pulse width changes remained contradictory in previous studies. In this work, we use laser speckle contrast imaging (LSCI) to study the spatiotemporal CBF response to hindpaw somatosensory stimulation of different pulse widths (0.3 ms vs 1 ms) and current amplitudes (3 mA vs 6 mA) in a rodent experiment. The results showed that the change of pulse width significantly affected the CBF peak value at a lower current level (p<;0.05). In addition, the duration for observing significantly different average CBF response, denoted as td, at various pulse widths, was dependent on stimulus current amplitude. At a lower amplitude (3 mA), td was 6.5 s; While at a higher amplitude (6 mA), td was 2.5 s. It was indicated that the changes of pulse width had longer influence on the average CBF response at a lower current amplitude. Our findings may help to understand and explain the inconsistent AFC with different stimulation parameters in fundamental brain physiology.

Abstract
We previously identified a novel inhibitor of La protein, H11, which inhibited hepatitis B virus (HBV) replication by inhibiting the interaction between La protein and HBV RNA. However, the other cellular factors involved in this process remain unclear. To investigate the mechanism of H11-mediated inhibition of HBV infection, a lncRNA microarray analysis was performed using H11-treated and untreated stable HBV-expressing human hepatoblastoma HepG2.2.15 cells. The profiles of differentially expressed lncRNAs and mRNAs were generated and analysed using Gene Ontology (GO) and pathway analyses. The microarray data showed that 61 lncRNAs were upregulated, 74 lncRNAs were downregulated, 43 mRNAs were upregulated, and 44 mRNAs were downregulated in H11 treatment group when compared with the control group, and these results were consistent with qRT-PCR expression data. Bioinformatic analysis indicated that the differentially expressed lncRNAs were involved in RNA-mediated post-transcriptional gene silencing, regulation of viral genome replication and Jak-STAT signalling and apoptosis pathways. GO analysis showed that differentially expressed mRNAs were enriched in negative regulation of the Wnt signalling pathway and negative regulation of growth. Pathways analysis indicated that the differentially expressed mRNAs were involved in regulation of nuclear β-catenin signalling and target gene transcription, as direct p53 effectors, and in the peroxisome proliferator-activated receptors signalling and peroxisome pathways. Microarray data and qRT-PCR results indicated that H11 mediates inhibition of HBV replication by regulating the Wnt, β-catenin and PPAR signalling pathways.

Abstract
Pre-eclampsia is a common obstetric complication globally responsible for a significant burden of maternal and perinatal morbidity and mortality. Central to its pathophysiology is the anti-angiogenic protein, soluble fms-like tyrosine kinase-1 (sFLT-1). sFLT-1 is released from a range of tissues into the circulation, where it antagonizes the activity of vascular endothelial growth factor and placental growth factor leading to endothelial dysfunction. It is this widespread endothelial dysfunction that produces the clinical features of pre-eclampsia including hypertension and proteinuria. There are multiple splice variants of sFLT-1. One, known as sFLT-1 e15a, evolved quite recently and is only present in humans and higher order primates. This sFLT-1 variant is also the main sFLT-1 secreted from the placenta. Recent work has shown that sFLT-1 e15a is significantly elevated in the placenta and circulation of women with pre-eclampsia. It is also biologically active, capable of causing endothelial dysfunction and the end-organ dysfunction seen in pre-eclampsia. Indeed, the over-expression of sFLT-1 e15a in mice recapitulates the pre-eclamptic phenotype in pregnancy. Therefore, here we propose that sFLT-1 e15a may be the sFLT-1 variant primarily responsible for pre-eclampsia, a uniquely human disease. Furthermore, this placental-specific sFLT-1 variant provides promise for use as an accurate biomarker in the prediction or diagnosis of pre-eclampsia.

Abstract
Summary
Objectives:
A non-invasive method to monitor the functioning of the autonomous nervous system consists in heart rate variability (HRV) analysis. The aim of this study was to investigate the changes on HRV after an asphyxia experiment in rats, using several linear (time and frequency domain) and nonlinear parameters (approximate entropy, SD1 and SD2 indices derived from Poincare plots).
Methods:
The experiments involved the study of HRV changes after cardiac arrest (CA) resulting from 5 min of hypoxia and asphyxia, followed by manual resuscitation and return of spontaneous circulation. 5 min stationary periods of RR intervals were selected for further analysis from 5 rats in following distinct situations: 1) baseline, 2) 30 min after CA, 3) 60 min after CA, 4) 90 min after CA, 5) 120 min after CA, 6) 150 min after CA. The ANS contribution has been delineated based on time and frequency domain analysis.
Results and Conclusions:
The results indicate that the recovery process following the asphyxia cardiac arrest reflects the impaired functioning of the autonomic nervous system. Both linear and nonlinear parameters track the different phases of the experiment, with an increased sensitivity displayed by the approximate entropy (ApEn). After 150 min the ApEn RRI parameter recovers to its baseline value. The results forward the ApEn as a more sensitive parameter of the recovery process following the asphyxia.

Abstract
The coupling between neuronal activity and cerebral blood flow(CBF), known as neurovascular coupling, serves as the basis of functional brain imaging. Optogenetics provides a precise and selective approach to manipulate the activity in cell-specific neurons. It has been used in neuroscience research for comprehensive understanding about the light-evoked neurovascular coupling in rodent neuronal circuits. However, the spatiotemporal CBF response characteristics under different stimulus parameters such as pulse width and frequency remains unclear due to the lack of efficient CBF imaging technology. In this work, we used laser speckle contrast imaging(LSCI) to study the spatiotemporal hemodynamic response to optogenetic stimulation with different pulse widths (5ms, 10ms, 20ms) and frequencies (5Hz, 10Hz, 20Hz) in Channelrhodopsin-2(ChR2) expressing rats. The results showed that the averaged CBF response generally increased along with higher pulse width or frequency. The CBF peak response was significantly higher at 20ms and it took significantly shorter time to reach response peak at 5Hz. Our work adds additional insights in understanding the cell-specific neurovascular coupling mechanism and provides informative reference when applying ChR2 optogenetics in neurological disease research.

Structural and functional neuroimaging studies have indicated that the cortico-striato -thalamo-cortical (CSTC) circuit contributes to the pathophysiology of obsessive compulsive disorder (OCD). As an essential component of CSTC circuit, the dorsal anterior cingulate cortex (dACC) plays an important role for its advanced function in cognition and emotion control. A comprehensive understanding of the dACC disruption in OCD pathological mechanism is desired. In this study, we performed a combined diffusion tensor imaging (DTI) and magnetic resonance spectroscopy (MRS) study in 15 OCD patients and 15 healthy controls to investigate the association between structural abnormality and metabolic alterations within the dACC area. We found a positive correlation between the dACC fractional anisotropy (FA) value and choline concentration in patients. Moreover, the FA was positively associated with OCD clinical symptom, especially the compulsive behavior, which showed the clinical relevance of dACC white matter integrity in OCD. To our knowledge, the present work is the first combined DTI-MRS study of OCD. Our findings demonstrated the co-occurrence of structural and metabolic changes within dACC in OCD patients. It was suggested that the disrupted white matter integrity might be accompanied with degraded cellular membrane turnover.

Abstract
Women are at a twofold higher risk of developing major depressive disorder (MDD) than that of men. However, the investigation of female MDD patients functional brain activity is rare and the detailed mechanism remains unclear. The present work is to explore the altered spontaneous neural activity measured with regional homogeneity (ReHo) in female MDD patients using resting-state functional magnetic resonance imaging (fMRI) technique. Twelve MDD females and twelve matched healthy participants were included in the study. The ReHo analysis method was used to detect regional homogeneity features across the whole brain. Increased ReHo value was found in the left anterior cingulate gyrus (ACC_L) and right fusiform gyrus, and decreased ReHo value in the right putamen, left middle frontal gyrus and left middle occipital gyrus was shown in female MDD patients compared to healthy controls. Also, a significant positive correlation between patients ReHo value and HAMA score (r = 0.59, p = 0.045) was found in the ACC_L. The study of spontaneous neuronal activity alteration using ReHo analysis improves our understanding about the mechanism of female depression.

Abstract
Emerging evidence has suggested that the pathophysiology of obsessive compulsive disorder (OCD) might involve widely distributed large-scale brain systems. The dysfunction within salience network, which is comprised of dorsal anterior cingulated cortex (dACC) and bilateral insular areas, has been proposed to contribute to OCD onset. The mechanism underlying salience network abnormality remains unclear and it is worthwhile to investigate its clinical relevance using functional neuroimaging approaches. In this study, we performed the spontaneous brain activity measurement using resting-state functional magnetic resonance imaging (fMRI) on unmedicated OCD patients (n=23). Specifically, the amplitude of low frequency (0.01-0.08 Hz) fluctuations (ALFF) was calculated for regions in salience network. The voxel-based Pearson's correlative analysis was conducted to explore the relationship beween ALFF measures and symptom severity for OCD patients. The results showed that the spontaneous neuronal activity in insula was significantly correlated to OCD clinical symptoms, especially compulsive behaviors. Our findings consolidated that the salience network played an important role in the pathogenesis of OCD and the intensity of intrinsic brain activity in insula provided a predictive biomarker for OCD symptom severity.
