benzofurans and Asthma

Unprecedented community containment measures were taken following the recent outbreak of COVID-19 in Italy. The aim of the study was to explore the self-reported future compliance of citizens with such measures and its relationship with potentially impactful psychological variables.. An online survey was completed by 931 people (18-76 years) distributed across the Italian territory. In addition to demographics, five dimensions were measured: self-reported compliance with containment measures over time (today, at 7, 14, 30, 60, 90, and 180 days from now) at three hypothetical risk levels (10, 50, 90% of likelihood of contracting the COVID-19), perceived risk, generalized anxiety, intolerance of uncertainty, and relevance of several psychological needs whose satisfaction is currently precluded.. The duration of containment measures plays a crucial role in tackling the spread of the disease as people will be less compliant over time. Psychological needs of citizens impacting on the compliance should be taken into account when planning an easing of the lockdown, along with interventions for protecting vulnerable groups from mental distress.. La apendicitis aguda (AA) es la urgencia quirúrgica abdominal más frecuente. No encontramos estudios específicos que evalúen el impacto de la pandemia causada por el coronavirus 2 (SARS-Cov-2) sobre la AA y su tratamiento quirúrgico. Analizamos la influencia de esta nueva patología sobre la AA.. Estudio observacional retrospectivo en pacientes intervenidos por AA desde enero hasta abril de 2020. Fueron clasificados según el momento de la apendicectomía, antes de la declaración del estado de alarma (Pre-COVID19) y después de la declaración del estado de alarma (Post-COVID19) en España. Se evaluaron variables demográficas, duración de la sintomatología, tipo de apendicitis, tiempo quirúrgico, estancia hospitalaria y complicaciones postoperatorias.. La pandemia por SARS-Cov-2 influye en el momento de diagnóstico de la apendicitis, así como en su grado de evolución y estancia hospitalaria. La peritonitis fue lo más frecuentemente observado. Una sospecha y orientación clínica más temprana, es necesaria para evitar un manejo inadecuado de este trastorno quirúrgico común.. The primary outcome is improvement in PaO. Findings will provide timely information on the safety, efficacy, and optimal dosing of t-PA to treat moderate/severe COVID-19-induced ARDS, which can be rapidly adapted to a phase III trial (NCT04357730; FDA IND 149634).. None.. The gut barrier is crucial in cirrhosis in preventing infection-causing bacteria that normally live in the gut from accessing the liver and other organs via the bloodstream. Herein, we characterised gut inflammation by measuring different markers in stool samples from patients at different stages of cirrhosis and comparing this to healthy people. These markers, when compared with equivalent markers usually measured in blood, were found to be very different in pattern and absolute levels, suggesting that there is significant gut inflammation in cirrhosis related to different immune system pathways to that seen outside of the gut. This provides new insights into gut-specific immune disturbances that predispose to complications of cirrhosis, and emphasises that a better understanding of the gut-liver axis is necessary to develop better targeted therapies.. La surveillance de l’intervalle QT a suscité beaucoup d’intérêt durant la pandémie de la COVID-19 en raison de l’utilisation de médicaments prolongeant l’intervalle QT et les préoccupations quant à la transmission virale par les électrocardiogrammes (ECG) en série. Nous avons posé l’hypothèse que la surveillance en continu de l’intervalle QT par télémétrie était associée à une meilleure détection des épisodes de prolongation de l’intervalle QT.. Nous avons introduit la télémétrie cardiaque en continu (TCC) à l’aide d’un algorithme de surveillance automatisée de l’intervalle QT dans nos unités de COVID-19. Les mesures automatisées quotidiennes de l’intervalle QT corrigé (auto-QTc) en fonction de la fréquence cardiaque maximale ont été enregistrées. Nous avons comparé la proportion des épisodes de prolongation marquée de l’intervalle QTc (QTc long), définie par un intervalle QTc ≥ 500 ms, chez les patients montrant une suspicion de COVID-19 ou ayant la COVID-19 qui avaient été admis avant et après la mise en place de la TCC (groupe témoin. La surveillance en continu de l’intervalle QT est supérieure à la norme de soins dans la détection des épisodes de QTc long et exige peu d’ECG. La réponse clinique aux épisodes de QTc long est sous-optimale.. Exposure to a model wildfire air pollution source modifies cardiovascular responses to HC challenge, suggesting air pollution sensitizes the body to systemic triggers.. Though the majority of HIV-infected adults who were on HAART had shown viral suppression, the rate of suppression was sub-optimal according to the UNAIDS 90-90-90 target to help end the AIDS pandemic by 2020. Nonetheless, the rate of immunological recovery in the study cohort was low. Hence, early initiation of HAART should be strengthened to achieve good virological suppression and immunological recovery.. Dust in Egyptian laying hen houses contains high concentrations of microorganisms and endotoxins, which might impair the health of birds and farmers when inhaled. Furthermore, laying hens in Egypt seem to be a reservoir for ESBL-producing Enterobacteriaceae. Thus, farmers are at risk of exposure to ESBL-producing bacteria, and colonized hens might transmit these bacteria into the food chain.. The lack of significant differences in the absolute changes and relative ratios of injury and repair biomarkers by contrast-associated AKI status suggests that the majority of mild contrast-associated AKI cases may be driven by hemodynamic changes at the kidney.. Most comparisons for different outcomes are based on very few studies, mostly low-powered, with an overall low CoE. Thus, the available evidence is considered insufficient to either support or refute CH effectiveness or to recommend one ICM over another. Therefore, further well-designed, larger RCTs are required.. PROSPERO database Identifier: CRD42016041953.. Untouched root canal at cross-section perimeter, the Hero 642 system showed 41.44% ± 5.62% and Reciproc R40 58.67% ± 12.39% without contact with instruments. Regarding the untouched area, Hero 642 system showed 22.78% ± 6.42% and Reciproc R40 34.35% ± 8.52%. Neither instrument achieved complete cross-sectional root canal debridement. Hero 642 system rotary taper 0.02 instruments achieved significant greater wall contact perimeter and area compared to reciprocate the Reciproc R40 taper 0.06 instrument.. Hero 642 achieved higher wall contact perimeter and area but, regardless of instrument size and taper, vital pulp during.

La evaluación de riesgo es importante para predecir los resultados postoperatorios en pacientes con cáncer gastroesofágico. Este estudio de cohortes tuvo como objetivo evaluar los cambios en la composición corporal durante la quimioterapia neoadyuvante e investigar su asociación con complicaciones postoperatorias. MÉTODOS: Los pacientes consecutivos con cáncer gastroesofágico sometidos a quimioterapia neoadyuvante y cirugía con intención curativa entre 2016 y 2019, identificados a partir de una base de datos específica, se incluyeron en el estudio. Se utilizaron las imágenes de tomografía computarizada, antes y después de la quimioterapia neoadyuvante, para evaluar el índice de masa muscular esquelética, la sarcopenia y el índice de grasa visceral y subcutánea.. In this in vitro premature infant lung model, HF oscillation of BCPAP was associated with improved CO. Our results showed that HPC significantly promotes neurogenesis after MCAO and ameliorates neuronal injury.. Inflammatory markers are highly related to signs of systemic hypoperfusion in CS. Moreover, high PCT and IL-6 levels are associated with poor prognosis.. These findings indicate that Tetrapleura tetraptera fruit has a protective potential against stroke through modulation of redox and electrolyte imbalances, and attenuation of neurotransmitter dysregulation and other neurochemical dysfunctions. Tetrapleura tetraptera fruit could be a promising source for the discovery of bioactives for stroke therapy.

There is an increasing interest in natural products and their derivatives with therapeutic benefits and less side effects compared to steroid therapy. Benzofuran derivatives display biological effects including anti-inflammatory effects. The present study aims to investigate whether (3-(7-methoxy-2-p-tolyl benzofuran-5-yl) propan-1-ol) (DK-1108), new synthetic benzofuran compound exerts anti-asthmatic effects in vitro and in vivo. DK-1108 strongly reduced the production of inflammatory mediators, cytokines and chemokines in RAW264.7 and A549 cells. DK-1108 significantly regulated the levels of AKT/MAPKs/c-Jun activation, AP-1 luciferase activity and ICAM-1 expression. Furthermore, DK-1108 effectively suppressed the adhesion of A549 and EOL-1 cells. In OVA-induced asthmatic mice, DK-1108 decreased the levels of IL-5/IL-13/IgE production, eosinophils/macrophages influx, ICAM-1/MCP-1 expression, mucus secretion and airway hyperresponsiveness (AHR). These effects of DK-1108 were accompanied by downregulation of MAPKs activation. Therefore, we suggest that DK-1108 exerts protective effect against airway inflammation and mucus overproduction, and therefore could be valuable therapeutic agent for treatment in asthma.

Butylphthalide (NBP) is a phthalide compound contained in Angelicae Sinensis Radix which is one of the most widely used traditional Chinese medicines. This study aims to explore the therapeutic effect of NBP on airway inflammation, mucus hypersecretion and their possible mechanism in asthma mice. BALB/c mice were sensitized and challenged with ovalbumin (OVA) for establishment of asthma model and then treated with NBP during day 22-77. The pulmonary function of the mice was determined, and the pathology of lung tissue and goblet cell hyperplasia were observed through analyzing inflammation scores and goblet cell percentage, respectively. Cytokine IL-4, IL-8, IL-13 and tumor necrosis factor-alpha (TNF-α) in bronchoalveolar lavage fluid (BALF) and total immunogloblin E (T-IgE) and OVA-specific IgE in serum were examined by enzyme-linked immunosorbent assay (ELISA). The expressions of Mucin 5AC (Muc5ac) and nuclear transcription factor-kappa B (NF-κB) in lung tissues were evaluated by immunohistochemistry, western blot and real-time polymerase chain reaction (RT-PCR). The results show that 50 mg/kg NBP significantly reduced OVA-induced increase in inflammation scoring, goblet cell percentage and mucus secretion of airway tissue, and improved the pulmonary function. NBP could also decrease IL-4, IL-8 IL-13, and TNF-α in BALF and T-IgE and OVA-specific IgE in serum. The expression of Muc5ac and NF-κB in lung tissue was significantly down-regulated after NBP treatment. This study suggested that NBP may effectively inhibit airway inflammation and mucus hypersecretion in asthma by modulating NF-κB activation.

Benzofuran derivatives have wide range of biological activities as anti-oxidant, anti-inflammatory and anticonvulsant agent. In this study, we investigated whether the novel benzofuran derivative, DK-1014 has the anti-inflammatory effects on macrophage and lung epithelial cells and anti-asthmatic effects on ovalbumin-treated mice. A series of 2-arylbenzofuran analogues were synthesized and evaluated for NO and interleukin-6 (IL-6) inhibition in LPS-stimulated Raw264.7 cells. Of these analogues, compounds 8, 22a, 22d, and 22 f (DK-1014) exhibited notable inhibitory activity with respect to IL-6 and NO production. In particular, compound DK-1014 strongly reduced IL-6, IL-8, and MMP-9 mRNA expression and IL-6, IL-8, and MCP-1 production in phorbol myristate acetate stimulated A549 cells, reduced MAPKs phosphorylation and c-fos translocation, and attenuated AKT, p70S6K and GSK phosphorylation. In vivo experiments were also performed on ovalbumin-sensitized and challenged BALB/c mice. DK-1014 reduced the airway hyperresponsiveness, inflammatory cell counts and cytokine levels (IL-4, 5, 13) in bronchial alveolar lavage fluid (BALF) and immunoglobulin E in serum, and attenuated inflammatory cell infiltration and mucus hypersecretion in lung tissue. These findings indicate that DK-1014 can protect against allergic airway inflammation through the AP-1 and AKT/mTOR pathways and could be useful source for the development of a therapeutic agent for asthma.

Salvianolic acid B (SalB) is one of the main water-soluble composites from Chinese medicine Dansen (Radix miltiorrhiza). It is used for clinical treatment of various diseases including cardiovascular, lung, Liver, renal and cancers. However, the effects of SalB to allergy induced airway mucin hypersecretion, inflammation and hyperresponsiveness (AHR) remains not clear. Overproduction of airway MUC5AC is a central effector of inflammation that is strongly associated with AHR in asthmatic attack. In this study, we investigated the anti-asthmatic activity and mechanism of SalB in a murine model and human epithelial cells by monitoring changes in mucin expression and secretion, airway inflammation, AHR, and signaling pathways. SalB was administered by intragastric administration (i.g) daily for a week, starting at 21 days after sensitization of ovalbumin (OVA). All examinations were performed 24h after the last antigen challenge. We found that treatments with SalB significantly inhibited increase in the tracheobronchial secretion, glycosaminoglycan levels, interleukin (IL)-13, IL-4, and IL-5 cytokines mRNA and protein expression, and decrease in mucociliary clearance in lung tissues. Histological results demonstrated that SalB attenuated OVA-induced eosinophil infiltration, airway goblet cell hyperplasia, and MUC5AC and MUC5B mRNA and protein expression in lung tissues. SalB exhibited protective effects against AHR in OVA-challenged animals. In vitro, SalB significantly inhibited IL-13-induced MUC5AC and MUC5B mRNA and protein expression in human epithelial cells. These effects were blocked by SalB by downregulating the Erk1/2 and P38 signaling pathways. Taken together, these data indicate that treatment with SalB may improve AHR by inhibiting MUC5AC overproduction.

The current study was aimed to investigate the effect of benzofuran on asthma neonatal rat model. Twenty-five neonatal rats were assigned into five groups; Normal control, untreated, 1 mg/kg, 8 mg/kg and 10 mg/kg treatment groups. Methacholine was administered orally to the rats of untreated and treatment groups. Animals in the normal control group were given PBS as a vehicle. FlexiVent system employing a computer-controlled mouse ventilator along with respiratory mechanics was used for the analysis of airway resistance in the rats. Cytokine level and IFN-γ in the rat serum samples was performed by ELISA in accordance with the instructions of manufacturer. Methacholine administration into the rats caused a marked increase in lung airway resistance. However, treatment with 8 and 10 mg/kg doses of benzofuran led to marked decrease in the airway resistance. Benzofuran treatment prevented accumulation of macrophages and inflammatory cells in the lung airways. Inhibition of inflammation in methacholine administered rats by benzofuran was also confirmed by hematoxylin & eosin-staining. Examination of the rat serum showed significantly higher level of Th2 cytokines (IL-4, -5 and -13) in the untreated rats. However, treatment of methacholine administered rats with benzofuran significantly inhibited Th2 cytokine expression. The level of IFN-γ was increased by benzofuran treatment in methacholine administered rats. In methacholine administered rats the level of IgE was markedly higher however treatment of asthma rats with benzofuran inhibited up-regulation of IgE significantly. The expression of T-bet is decreased and that of GATA-3 is increased by methacholine administration in the rat lungs. Benzofuran treatment of methacholine administered rats prevented reduction in T-bet and up-regulation of GATA-3 expression in the rat lungs. The effect of benzofuran was significant at the doses of 8 and 10 mg/kg and non-significant at 1 mg/kg. These finding suggest that benzofuran inhibits expression of dominant T-helper 2 cytokines through targeting GATA-binding protein 3 transcription factor. Thus benzofuran can be of therapeutic importance for the treatment of asthma.

To study the anti-asthmatic effects of butylphthalide in guinea pig.. Butylphthalide at the concentrations of 1、10、100 mg/L had an-ti-spasmodic effects on spasmodical tracheal smooth muscle of guinea pig (15.08 ±7.68、42.41 ±13.54、77.56 ±24.82 to acetylcholine, 19.40 ±7.60、56.84 ±11.72、76.35 ±19.40 to histamine), which showed a certain dose-effect relationship. Butylphthalide could prolong asth-matic incubation period (53.3 ±13.2、33.1 ±13.0), improve asthmatic behaviors, reduce NO in serum (78.71 ±19.40、84.75 ±20.97) and ET-1 in bronchoalveolar lavage fluid (24.30 ±5.80、28.50 ±6.31) (. Butylphthalide has some effects of anti-asthma and one of the mechanisms is to relieve abnormal increase of NO and ET-1.

To study the effects of butylphthalide on bronchial asthma in guinea pigs, and investigate the involvement of endothelin.. In guinea pigs, bronchial asthma was induced by injection of ovalbumin (OVA) and provoked by inhalation of OVA, and the effects of butylphthalide on asthma were evaluated through the changes it induced by OVA, pulmonary function, endothelin-1 (ET-1) contents and activity of endothelin converting enzyme-1 (ECE-1) in bronchoalveolar lavage fluid (BALF), serum and lung tissue, and the gene expression of ET-1 in lung tissue.. Butylphthalide significantly improved pulmonary function, lowered asthmatic behavior score, inhibited the activity of ECE-1, and reduced ET-1 gene expression level in lung tissue.. Butylphthalide has an anti-asthma effect and the mechanisms involve inhibition of ECE-1 activity and lowering of ET-1geng expression.

Homoegonol is a lignan derived from styraxlignolide A, which was isolated from Styrax japonica, a medicinal plant widely used for treatment of inflammatory diseases in Korea. We investigated the efficacy of homoegonol for the treatment of allergic asthma using an ovalbumin (OVA)-induced murine asthma model. The mice were sensitized through intraperitoneal injections of OVA on days 0 and 14. On days 21, 22 and 23 after the initial OVA sensitization, the mice were received OVA airway challenge. Homoegonol was administered by oral gavage at a dose of 30 mg/kg 1 h prior to the OVA challenge. The homoegonol-treated mice exhibited reduced inflammatory cell counts and Th2 cytokines in BALF, AHR, and IgE in the serum compared with the OVA-sensitized/challenged mice. The histological analysis of the lung tissue revealed that the administration of homoegonol attenuated the airway inflammation and the mucus overproduction in airway epithelial lesions induced by OVA through a reduction in expression of inducible nitric oxide synthase and matrix metalloproteinase-9. These findings indicate that homoegonol effectively suppresses the asthmatic responses induced by OVA challenge and suggests that homoegonol exhibits potential as therapeutic drug for allergic asthma.

The aim of the present study is to investigate the effects of Vam3 which is one of the dihydroxystilbene compounds on expressions of ICAM-1 in the lungs of OVA-induced asthmatic mice and the mechanisms of anti-airway inflammation. Balb/c mice were challenged with OVA inhalation. Lung tissues were stained with Mayer's hematoxylin and eosin for histopathologic examination. The expression of ICAM-1 in the lungs of mice was analyzed by Western blotting and immunohistochemistry method. The NF-kappaB activities were detected by NF-kappaB-luc reporter genetic transient transfection method. The activities of MMP-9 induced by LPS, TNF-alpha and PMA in THP-1 cells were determined by gelatin zymography method. The results showed that Vam3 could inhibit the expression of ICAM-1 in the OVA-induced mouse model. In addition, Vam3 could significantly suppress the activities of NF-kappaB in A549 cells and MMP-9 in THP-1 cells induced by LPS, TNF-alpha and PMA. These results suggested that Vam3 could alleviate the asthmatic inflammation by decreasing ICAM-1 expression in asthmatic mice, down regulating NF-kappaB and MMP-9 activities. Compound Vam3 showed inhibitory effects on inflammatory signal pathways involved in asthma.

To explore the anti-inflammatory effects of amurensin H on asthma-like reaction induced by allergen in sensitized mice.. BALB/c mice were sensitized by ovalbumin (OVA, ip) on d 0 and d 14 and challenged with 1% OVA on d 18 to 22. Mice developed airway eosinophilia, mucus hypersecretion, and elevation in cytokine levels. Mice were administered amurensin H orally at the doses of 49, 70, or 100 mg/kg once every day from d 15 to the last day. Bronchoalveolar lavage fluid (BALF) were collected at 24 h and 48 h after the last OVA challenge. Levels of tumor necrosis factor-alpha (TNF-alpha), interleukin 4 (IL-4), interleukin 5 (IL-5), and interleukin 13 (IL-13) in BALF were measured using ELISA method. Differential cell counts of macrophages, lymphocytes, neutrophils and eosinophils were performed in 200 cells per slide (one slide per animal). Lung tissue sections of 6-mum thickness were stained with Mayer's hematoxylin and eosin for assessment of cell infiltration, mucus production, and tissue damage.. Oral administration of amurensin H significantly inhibited OVA-induced increases in total cell counts, eosinophil counts, and TNF- alpha, IL-4, IL-5 and IL-13 levels in BALF. In addition, amuresin H dramatically decreased OVA-induced lung tissue damage and mucus production.. Amurensin H may have therapeutic potential for the treatment of allergic airway inflammation.

The peptidoleukotrienes and leukotriene B4, formed from arachidonic acid through the action of 5-lipoxygenase (5-LO), exert a spectrum of biological effects. It has been proposed that potent and selective 5-LO inhibitors will be effective therapy in diseases in which the peptidoleukotrienes and leukotriene B4 have been implicated, such as asthma and arthritis. The novel compound (S)-N-hydroxy-N-(2,3-dihydro-6-phenylmethoxy-3-benzyofuranyl )urea (SB 202235) was evaluated as a selective inhibitor of 5-LO in a cell-free system as well as in various cellular assays. In addition, the potential therapeutic value of SB 202235 was assessed in preclinical models of allergic asthma. The activity of the 5-LO enzyme isolated from rat basophilic leukemia-1 cells was inhibited by SB 202235 in a concentration-dependent manner with an IC50 value of 1.9 microM. Consistent with its ability to inhibit 5-LO, SB 202235 inhibited the production of leukotriene B4 by human monocytes and in human whole blood (IC50 values of 1.5 microM and 1.1 microM, respectively). The selectivity of SB 202235 was confirmed by its lack of effect against several other enzymes and receptors. SB 202235 potently and effectively inhibited the contraction produced by a single concentration of ovalbumin in guinea pig trachea (IC50 = 20 microM) and of anti-IgE in human bronchus (IC50 = 2 microM). SB 202235 (3-30 microM) also inhibited the contraction of guinea pig trachea in response to increasing concentration of ovalbumin. When administered orally (30 mg/kg) to conscious guinea pigs, SB 202235 attenuated antigen-induced broncho-constriction and the subsequent eosinophil influx.(ABSTRACT TRUNCATED AT 250 WORDS)

The functional characteristics of platelets were estimated in patients with different asthma forms (atopic, aspirin-sensitive and mixed ones). It was shown that platelets of asthmatics with the atopic and aspirin-sensitive disease forms are more sensitive to the stimulating action of platelet activating factor (PAF) in aggregation response and intracellular Ca2+ influx induction than platelets of patients suffering mostly from the recurrent bronchopulmonary infections with atopic component (so-called "mixed" asthma) and more activated than platelets of healthy donors. Intracellular Ca2+ influx was measured using the fluorescent probe Fura-2 in platelet suspension. Platelet aggregation was measured on aggregometer by two methods (Born's method and correlational photometric method) in platelet-rich plasma. PAF was used as inductor of platelet aggregation and fluorescence response. The antiallergic drugs ketotifen and sodium cromoglycate (intal) caused a 30-40% inhibition of PAF-induced aggregation of asthmatics' and healthy donors' platelets. It may be concluded that platelets of atopic and aspirin asthmatics are more active, their "hyper-reaction" to PAF is expressed by higher aggregability and the lower PAF concentration threshold.

We describe a patient with bronchial asthma whose respiratory symptoms worsened during treatment and rechallenge with amiodarone. Laboratory studies on cultured pulmonary cells demonstrated an anti-beta-adrenergic effect of amiodarone not due to inhibition of beta-adrenergic receptor binding. Amiodarone should be used with caution in patients with obstructive pulmonary disease.
