Platelets are critical in the formation of thrombi, and their most potent trigger is platelet activating factor (PAF). PAF is produced by cells involved in host defense, and its biological actions bear similarities with COVID-19 disease manifestations, including pulmonary microthromboses and inflammation, possibly via activation of mast cells. The histamine1 receptor antagonist rupatadine was developed to have anti-PAF activity and inhibits activation of human mast cells in response to PAF. Rupatadine could be repurposed for COVID-19 prophylaxis.
Widespread antibiotic-resistant bacteria are threatening the arsenal of existing antibiotics. Not only are antibiotics less likely to be effective today, but their extensive use continues to drive the emergence of multidrug-resistant pathogens. A new-old antibacterial strategy with bacteriophages (phages) is under development, namely, phage therapy. Phages are targeted bacterial viruses with multiple antibacterial effector functions, which can reduce multidrug-resistant infections within the human body. This review summarizes recent phage therapy clinical trials and patient cases and outlines the fundamentals behind phage treatment strategies under development, mainly through bench-to-bedside approaches. We discuss the challenges that remain in phage therapy and the role of phages when combined with antibiotic therapy.

This narrative review presents the current knowledge and latest findings regarding phage therapy. Relevant case reports and research articles available through the Scopus and PubMed databasarch is needed before the clinical implementation is feasible, phage therapy may well be pivotal in safeguarding humans against antibiotic-resistant infections.
Although more translational research is needed before the clinical implementation is feasible, phage therapy may well be pivotal in safeguarding humans against antibiotic-resistant infections.Premedication in the pediatric population is of vital importance to reduce anxiety and facilitate anesthetic induction. Midazolam and ketamine have been used for this purpose, drugs that have shown long-term changes in neurodevelopment. Dexmedetomidine promotes a sedative, analgesic effect and lacks neurotoxic effects, its intranasal application is easy and minimally invasive. We studied the sedative and behavioral effect of intranasal dexmedetomidine 2 mcg/kg in ASA 1 and 2 children for elective surgery. They were evaluated at 10, 20 and 30 minutes of administered, in the separation of the parents and placement of the mask for inhalation induction with behavioral and sedation scores (classified from 1 to 4), we considered acceptable for admission to operating room categories 3 and 4. RESULTS Thirty patients between 1 and 10 years old were included in the period from September 2017 to April 2018. The sedation score obtained at 30minutes was acceptable in 46.6% of the patients and the behavior score was in 96% of the cases. In 63% of cases the acceptance of the facial mask placement for inhalation induction was achieved. The procedure was well tolerated in all cases and parents were satisfied in 100% of the cases.Lysophosphatidic acid (LPA) through six subtypes of G protein-coupled LPA receptors (LPA1 to LPA6) mediates a variety of cancer cell functions. The aim of this study was to evaluate the cooperative effects of G12/13 and Gi proteins through LPA2 on cancer cell survival to cisplatin (CDDP). In cell survival assay, cells were treated with CDDP every 24 h for 2 days. The long-term CDDP treated (HT-CDDP) cells established from fibrosarcoma HT1080 cells were pretreated with an LPA2 agonist, GRI-977143. The cell survival rate to CDDP of HT-CDDP cells was significantly increased by GRI-977143. The elevated cell survival to CDDP was suppressed by LPA2 knockdown. Since G12/13 protein stimulates Rho-mediated signaling, RhoA and RhoC knockdown cells were generated from HT1080 cells (HT1080-RhoA and HT1080-RhoC cells, respectively). In the presence of GRI-977143, HT1080-RhoA and HT1080-RhoC cells showed the low cell survival rates to CDDP. On the other hand, Gi protein inhibits adenylyl cyclase (AC) activity. Before cell survival assay, cells were treated with a Gi protein inhibitor, pertussis toxin (PTX) for 24 h. The cell survival rate to CDDP of HT1080 cells was significantly reduced by PTX. Furthermore, when HT1080-RhoA and HT1080-RhoC cells were pretreated with PTX, the cell survival rates to CDDP of both cells were markedly inhibited by PTX. The present results suggest that cooperation of G12/13 and Gi proteins activated by LPA2 enhances the cell survival of HT1080 cells treated with CDDP.Non-alcoholic fatty liver disease (NAFLD) was associated with increased level of lipopolysaccharides (LPS) which mechanism remained unclear on intervention between LPS and NAFLD. The aim was to explore the IKKε/NF-κB role and its intervention of LPS and high-fat diet (HFD) induced NAFLD. Male C57BL/6 mice were fed on high-fat diet (HFD) combined with or without simultaneously subcutaneous injection of LPS for 18 weeks. Body weight , blood biochemistry parameters, inflammatory mediator and liver lipid deposition were measured to evaluate LPS effect on NAFLD. Furthermore, IKKε selective inhibitor amlexanox (AM) was administrated by gavage to HFD + LPS induced mice. The indicators about metabolism and inflammation were examined and qRT-PCR, immunoblotting assay as well as immunohistochemistry were performed to assess IKKε/NF-κB activation and downstream gene expression. This study found that low-dose LPS + HFD aggravated more significant steatosis than simple HFD or high-dose LPS + HFD. Low-dose LPS exacerbated more prominent inflammation profile including increased IKKε and NF-κB expression in liver than HFD. Inhibiting IKKε/NF-κB signaling with amlexanox significantly prevented HFD + LPS induced metabolic disorders and hepatic steatosis. LPS-upregulated gene expression involved in glucolipid metabolism could be downregulated by amlexanox. Thus, the present study confirmed long-term combinational administration of subcutaneous low-dose LPS injection and HFD induced NAFLD model which had more significant phenotype in mice than simple HFD or high-dose LPS-induction. Targeting on IKKε/NF-κB signaling with its inhibitor amlexanox alleviated steatohepatitis, suggesting that IKKε/NF-κB signaling was responsible for effect of LPS and HFD on NAFLD.At present, fish provide an important supply of long-chain polyunsaturated fatty acids (LC-PUFAs) for human consumption. Previous studies have shown that fatty acyl elongase 2 (elovl2) and elovl5 play important roles in fish LC-PUFA synthesis. Generally, freshwater fish have a stronger ability to synthesize LC-PUFAs than marine fish. However, the roles of elovl2, elovl5 and elovl2 + elovl5 in LC-PUFA synthesis of freshwater fish in vivo are not very clear. In this study, the elovl2 knockout zebrafish (elovl2-/-), elovl5 knockout zebrafish (elovl5-/-) and the double gene knockout zebrafish (DKO) were generated by CRISPR/Cas9 technology for the first time. Compared with wild type zebrafish (WT), elovl5-deletion zebrafish showed a significant increase in C22 PUFA content, which might be due to the up-regulation expressions of elovl4b and elovl2. elovl5 expressed at very low levels in livers of elovl2-/- relative to WT, indicating that elovl5 may be an "assistant attacker" of elovl2 in LC-PUFA synthesis of zebrafish. #link# Moreover, there were no significant differences in levels of C18-C22 PUFAs between DKO and WT, indicating that besides elovl2 + elovl5 path, LC-PUFA synthesis in zebrafish could be performed by other paths. In addition, the hepatic lipidomic analysis results revealed that the contents of C226n-3 in phosphatidyl ethanolamine (PE-DHA) and PE-C22 PUFAs were more easily affected by the absence of elovl2 and elovl5. Our results suggest that the elovl2+elovl5 path is not the only path for LC-PUFA synthesis in zebrafish, and provide novel insights into the roles of elovl2 and elovl5 in LC-PUFA synthesis of freshwater fish.Embryonic stem (ES) cells are unique in their ability to self-renew indefinitely while maintaining pluripotency. Krüppel-like factor (Klf) 4 is an important member of the Klf family that is known to play a key role in pluripotency and somatic cell reprogramming. link2 However, the identification and functional comparison of Klf4 splicing isoforms in mouse ESCs (mESCs) remains to be elucidated. Here, we identified three novel alternative splicing variants of Klf4 in mESCs-mKlf4-108, mKlf4-375 and mKlf4-1482-that are distinct from the previously known mKlf4-1449. mKlf4-1449 and mKlf4-1482 may stimulate the growth of ESCs, while mKlf4-108 can only promote the growth of ESCs in LIFlow/serum conditions. In read more , both mKlf4-1449 and mKlf4-1482 can inhibit the differentiation of mESCs. However, the ability of mKlf4-1482 to promote self-renewal and inhibit differentiation is not as strong as that of mKlf4-1449. In contrast, both mKlf4-108 and mKlf4-375 may have the ability to induce endodermal differentiation. Taken together, we have identified for the first time the existence of alternative splicing variants of mKlf4 and have revealed their different roles, which provide new insights into the contribution of Klf4 to the self-renewal and pluripotency of mouse ESCs.The HCMV (human cytomegalovirus) encodes numerous proteins which function to evade the immune response, which allows the virus to replicate. Exploring the mechanisms of HCMV immune escape helps to find the strategy to inhibit HCMV replicate. CD8+ T cells play a critical role in the immune response to viral pathogens. However, the mechanisms of HCMV to evade the attack by CD8+ T cells remain largely unknown. Viral CXCL1 (vCXCL1) is the production of HCMV UL146 gene. Here, we found that vCXCL1 promoted the resistance of hepatic cells to CD8+ T cells. vCXCL1 increased the levels of PD-L1 protein expression and mRNA expression. VCXCL1 enhanced the binding of STAT3 transcription factor to the promoter of PD-L1 and increased the activity of PD-L1 promoter. Furthermore, down-regulation of PD-L1 reduced the effects of vCXCL1 on the resistance of hepatic cells to CD8+ T cells. Taken together, vCXCL1 promotes the resistance of hepatic cells to CD8+ T cells through up-regulation of PD-L1. link3 This finding might provide a new mechanism of HCMV immune escape.The legislative and ideological transition produced in recent years in Spain has favoured the implementation of the community model of mental health care. However, there is still strong resistance to the inclusion of community approaches in the care of people with mental health problems and to the implementation of integrated care and attention with a salutogenic approach. The purpose of the following report is to describe the evolution of the community model of mental health care in the Spanish National Health System and to assess its current status. Initially, a review of the published national mental health plans and strategies was carried out. Subsequently, the evaluation was carried out taking as reference the Consensus Document on the Fundamental Principles and Key Elements of Community Mental Health, which establishes the criteria for evaluating the quality of community care. In the absence of updated plans or strategies, international reports and recommendations were included. The results were grouped into 1) social perspective, where the controversy about the capacity of the users to make decisions despite the recognition of their rights as autonomous moral agents is evident; 2) perspective of the centrality of the users of mental health care services, where the resistance to the implementation of integrated community care and attention is expressed; and 3) professional perspective in relation to the effectiveness of the interventions and the community network of care principles, which highlights the need to transform the institutions to carry out community interventions in mental health based on evidence and in an intersectoral, comprehensive, integrated and integrating manner.
