Therapeutic exploitation of redox mediators is being explored in other cardiovascular conditions, with potential application to TAA warranting further investigation.Conclusion Oxidative stress occurs in genetically triggered TAA, but the precise contribution of ROS to pathogenesis remains incompletely understood. Further research is required to define causative pathological relationships in order to develop therapeutic options.The endo-1,5-α-L-arabinanases, belonging to glycoside hydrolase family 43 (GH43), catalyse the hydrolysis of α-1,5-arabinofuranosidic bonds in arabinose-containing polysaccharides. These enzymes are proposed targets for industrial and medical applications. Here, molecular dynamics (MD), potential energy surface and free energy (potential of mean force) simulations are undertaken using hybrid quantum mechanical/molecular mechanical (QM/MM) potentials to understand the active site dynamics, catalytic mechanism and the electrostatic influence of active site residues of the GH43 endo-arabinanase from G. stearothermophilus. The calculated results give support to the single-displacement mechanism proposed for the inverting GH43 enzymes first a proton is transferred from the general acid E201 to the substrate, followed by a nucleophilic attack by water, activated by the general base D27, on the anomer carbon. A conformational change (2E ↔E3 ↔ 4E) in the -1 sugar ring is observed involving a transition state featuring an oxocarbenium ion character. Pexidartinib cost Residues D87, K106, H271 are highlighted as potential targets for future mutation experiments in order to increase the efficiency of the reaction. To our knowledge, this is the first QM/MM study providing molecular insights into the glycosidic bond hydrolysis of a furanoside substrate by an inverting GH in solution.Communicated by Ramaswamy H.

Severe life-threatening hypercalcaemia can occur as a late complication. A 2-month-old girl presented with severe hypercalcaemia and acute renal injury as a complication of SFN. She was admitted to hospital with the chief complaint of failure to thrive. She had a history of therapeutic hypothermia. After successful treatment of the hypercalcaemia with bisphosphonates, the acute renal injury recovered spontaneously. In neonates with SFN, acute renal injury is a rare complication of hypercalcaemia. Timely prevention of the complications of hypercalcaemia in SFN is essential.The antibacterial and antifungal effects of non-functionalized and surface-functionalized Mn3O4 nanoparticles were comparatively analyzed to reason out the potential changes in antimicrobial activities due to functionalization with 5-amino-2-mercapto benzimidazole (AMB) molecule. The surface functionalization of Mn3O4 nanoparticles with AMB molecule was confirmed by the XRD result, which shows the shift in 2θ values with noticeable peaks. The surface morphology and functionalization of Mn3O4 nanoparticles were additionally confirmed by HR-SEM and EDAX studies. Antimicrobial activities were investigated by an agar-well-diffusion method using the bacteria Staphylococcus aureus and Pseudomonas aeruginosa and fungi Aspergillus niger. The functionalized Mn3O4 nanoparticles possess remarkable antibacterial and antifungal effect than the non-functionalized Mn3O4 nanoparticles and AMB molecule. The coating of low energy surface layer over metal oxide nanoparticles such as Mn3O4 offers an active surface toward both transfer of electron and the adsorption or desorption of water, inorganic ions, and other molecules, which leads to the increased antimicrobial activity of f-Mn3O4 nanoparticles.Communicated by Ramaswamy H.

While vaccine candidates and therapeutics are currently undergoing clinical trials, there is a lack of proven effective treatments or cures for COVID-19. In this study, we have presented a synergistic computational platform, including molecular dynamics simulations and immunoinformatics techniques, to rationally design a multi-epitope vaccine candidate for COVID-19. This platform combines epitopes across Linear B Lymphocytes (LBL), Cytotoxic T Lymphocytes (CTL) and Helper T Lymphocytes (HTL) derived from both mutant and wild-type spike glycoproteins from SARS-CoV-2 with diverse protein conformations. In addition, this vaccine construct also takes the considerable glycan shield of the spike glycoprotein into account, which protects it from immune response. We have identified a vaccine candidate (a 35.9 kDa protein), named COVCCF, which is composed of 5 LBL, 6 HTL, and 6 CTL epitopes from the spike glycoprotein of SARS-CoV-2. Using multi-dose immune simulations, COVCCF induces elevated levels of immunoglobulin activity (IgM, IgG1, IgG2), and induces strong responses from B lymphocytes, CD4 T-helper lymphocytes, and CD8 T-cytotoxic lymphocytes. COVCCF induces cytokines important to innate immunity, including IFN-γ, IL4, and IL10. Additionally, COVCCF has ideal pharmacokinetic properties and low immune-related toxicities. In summary, this study provides a powerful, computational vaccine design platform for rapid development of vaccine candidates (including COVCCF) for effective prevention of COVID-19.Communicated by Ramaswamy H.

Visceral mediastinal tumors are rare with challenging surgical approaches due to their location in close proximity with the great vessels and the pulmonary trunk. The aim of this paper is to discuss surgical strategies for complex cases of primary mediastinal tumors.

We present two cases of patients with middle mediastinal tumor, one synovial sarcoma and one paraganglioma. For both patients, surgical access was performed through a sternotomy with beating heart cardio-pulmonary bypass and aortic transection, allowing optimal exposure of the carina, of the common pulmonary artery and its bifurcation. Both tumors were resected 'en-bloc'. The postoperative course was uneventful and the two patients had a 3 months postoperative follow-up CT-scan showing no evidence of recurrence.

Surgery remains the cornerstone of treatment for synovial sarcoma and for paraganglioma of the visceral mediastinum and this location may be difficult to deal with. Many different surgical accesses exist and our approach of ascending aortic transection allows optimal exposure to the pulmonary artery, but also provides access to the upper airways.
