In silico drug repurposing for the identification of potential candidate molecules against arboviruses infection. Antiviral Res. 2019 Nov 28;:104668 Authors: Montes-Grajales D, Puerta-Guardo H, Espinosa DA, Harris E, Caicedo-Torres W, Olivero-Verbel J, Martínez-Romero E Abstract Arboviral diseases caused by dengue (DENV), Zika (ZIKV) and chikungunya (CHIKV) viruses represent a major public health problem worldwide, especially in tropical areas where millions of infections occur every year. The aim of this research was to identify candidate molecules for the treatment of these diseases among the drugs currently available in the market, through in silico screening and subsequent in vitro evaluation with cell culture models of DENV and ZIKV infections. Numerous pharmaceutical compounds from antibiotics to chemotherapeutic agents presented high in silico binding affinity for the viral proteins, including ergotamine, antrafenine, natamycin, pranlukast, nilotinib, itraconazole, conivaptan and novobiocin. These five last compounds were tested in vitro, being pranlukast the one that exhibited the best antiviral activity. Further In vitro assays for this compound showed a significant inhibitory effect on DENV and ZIKV infection of human monocytic cells and human hepatocytes (Huh-7 cells) with potential abrogation of virus entry. Finally, intrinsic fluorescence analyses suggest that pranlukast may have some level of interaction with three viral proteins o...

The use of extracorporeal carbon dioxide removal (ECCO2R) has been used successfully to control pH and PaCO2 in patients with acute severe asthma. The present report describes the use of this technology in near-fatal asthma with brain death, and awaiting organ harvest.The ProLUNG® system consists of a veno-venous hemoperfusion circuit with an artif...

This study determined seroprevalence of active and past CHIKV infection among febrile patients who tested negative for malaria and typhoid fever. Sera from 243 febrile patients were screened for CHIKV IgG and IgM using an immunochromatographic test kit. Clinical and socio-demographic variables were collected using a structured questionnaire. Recent CHIKV infection was observed in 5.8% of the study participants while 25.1% had IgG antibodies demonstrating previous infection. Significant associations were observed between seropositivity and age of participants (p

It is difficult to discover novel bronchodilators, although potential new targets are emerging. Traditional Chinese Medicine (TCM) formulas have been used to treat asthma for more than ...

BY JESSICA DAMASSA BioLum Sciences is introducing new chemistry that has the potential to completely change the way we test for respiratory illnesses, like asthma, and analyze blood samples to identify hypertension. CEO Edward Allegra talks through the science behind both their breath and blood tests, both of which are patent-pending and have the ability to completely bend the cost-curve when it comes to identifying and monitoring these two common chronic conditions. What’s next for the early-stage health startup? A range of applications to detect everything from COPD to lung cancer and more. Filmed at Bayer G...

Omalizumab is an anti-IgE monoclonal antibody (mAb) approved for the treatment of severe asthma and chronic spontaneous urticaria. Use of omalizumab is associated with reported side effects ranging from local skin inflammation at the injection site to systemic anaphylaxis. To date, the mechanisms through which omalizumab induces adverse reactions are still unknown. Here, we demonstrated that immune complexes formed between omalizumab and IgE can induce both skin inflammation and anaphylaxis through engagement of IgG receptors (FcγRs) in FcγR-humanized mice. We further developed an Fc-engineered mutant version o...

Conclusion The results obtained from this research shows, in general, the fragility in the social and political infrastructure necessary to improve the living conditions of populations, particularly those that depend on family agriculture in drought prone areas. The conditions of social, economic and environmental vulnerabilities presented in the region can be amplified by the drought process, and can aggravate the impacts resulting drought events, thus disadvantaging the population of this region, as shown in the Fig. 1. The general perception of the interviewees of the health sector shows an agreement with what is found...
