We present the first case of levodopa-responsive juvenile parkinsonism associated with dihydropyrimidinase deficiency caused by a novel DPYS variant.

Degarelix limits the survival of mycobacteria and granuloma formation.

Tuberculosis (TB), caused by Mycobacterium tuberculosis (Mtb) infection, is a serious health hazard, characterized by tuberculous granuloma formation, which may facilitate bacterial survival. At the same time, the identification of multidrug-resistant and extremely drug-resistant Mtb strains, and the progressive accumulation of mutations in biological targets of frontline antimicrobials, has made TB treatments more difficult. Therefore, new and rapid drug development for TB is warranted.

The Plastic Deformation Mechanism in Nano-Polycrystalline Al/Mg Layered Composites: A Molecular Dynamics Study.

Understanding plastic deformation behaviour is key to optimising the mechanical properties of nano-polycrystalline layered composites. This study employs the molecular dynamics (MD) simulation to comprehensively investigate the effects of various factors, such as grain sizes, strain rates, and the interlayer thicknesses of the intermetallic compounds (IMCs), on the plastic deformation behaviour of nano-polycrystalline Al/Mg layered composites. Our findings reveal that the influence of grain size on deformation behaviour is governed by the strain rate, and an increase in grain size is inversely proportional to yield stress at low strain rates, whereas it is positively proportional to tensile stress at high strain rates.
