Global expansion of invasive plant species has caused serious ecological and economic problems. Two such invasive species, ragweed and horseweed, were pyrolyzed at temperatures of 350, 450 and 550 ℃ for biochar production (RB350, RB450, RB550 and HB350, HB450, HB550). The biochars produced were used for Cd(Ⅱ) and Pb(Ⅱ) removal in aqueous solutions. The results indicated that the properties of the biochars varied with pyrolysis temperature, which further affected their adsorption performance. The maximum adsorption capacity of RB450 for Cd(Ⅱ) (139 mg·g-1) and Pb(Ⅱ) (358.7 mg·g-1) was much higher than that shown in previous studies. The immobilized Cd(Ⅱ) and Pb(Ⅱ) fraction on RB450, RB550, HB450 and HB550 was mainly attributable to the acid soluble and non-available fractions. These findings suggested that pyrolysis of invasive plants at 450 ℃ could not only be an option to control invasive plants but also could be of benefit in using biochar as excellent adsorbent.A novel carboxylesterase AcEst1 was identified from Acinetobacter sp. JNU9335 with high efficiency in the biosynthesis of chiral precursor of Edoxaban through kinetic resolution of methyl 3-cyclohexene-1-carboxylate (CHCM). Devimistat nmr Sequence analysis revealed AcEst1 belongs to family IV of esterolytic enzymes and exhibits 99% (S) and substrate to catalyst ratio (S/C) of 3500 g·g-1. These results indicate that the novel AcEst1 is a promising biocatalyst in the synthesis of chiral carboxylic acids.In view of the potential applications of immobilized enzymes, partially purified Lignin Peroxidase (LiP) from Pseudomonas fluorescens LiP-RL5 was immobilized on Graphene Oxide functionalized MnFe2O4 nanoparticles (10 nm, synthesized by sol-gel auto-combustion) to fabricate a new hyperactive and thermostable nanobiocatalyst and thereafter characterized by using standard techniques. Immobilized LiP was quite stable at 50 °C with the half-life of 14 h and showed higher tolerance towards various metal ions and solvents than free LiP. Immobilized LiP retained 50% of enzyme activity even after nine consecutive runs. When tested against various textile dyes, the immobilized LiP was found quite effective with higher dye decolourization efficiency (up to 88%) within 1 h of incubation at 30 °C. The results of this research effort confirmed that the immobilization of LiP and fabrication of nanobiocatalyst increase the efficacy, stability, and reusability of the enzyme which could be efficiently utilized under harsh industrial conditions.Glial fibrillary acidic protein is a recently identified rare cause of autoimmune encephalomyelitis, in which the cerebrospinal fluid shows lymphocytic pleocytosis accompanied by linear perivascular radial gadolinium enhancement in the brain. We report a 19-year-old man admitted to the intensive care unit with suspected viral meningoencephalitis. Magnetic resonance imaging showed mild encephalopathy with a reversible splenial lesion. He quickly developed a coma and acute respiratory failure. Glial fibrillary acidic protein antibodies and human parainfluenza virus were detected by cerebrospinal fluid exams. He was treated with intravenous immunoglobulin, methylprednisolone pulses, plasma exchange and then six infusions of cyclophosphamide plus two of rituximab, which resulted in a total recovery. Radiation has been discussed as a potential causative factor for Multiple Sclerosis (MS). However, it is unresolved whether radiation increases the aggressiveness of the immune system or whether it alters the nervous tissue to become vulnerable to a pre-existing autoimmune attackdisposition. We report a patient with an MS-like disease confined to the irradiated part of his central nervous system (CNS). within the course of a year, a 29 year-old man developed three relapses that were distinguishable regarding their neurological signs and symptoms. Clinically and on MRI, all relapses were localised to the cervico-thoracic spinal cord (sen
