suis is not able to utilize glucose for its main energy supply
6 This study found an increased number of T cells in the olfactory epithelium as well as a decreased number of anti-inflammatory M2 macrophages, leading to heightened inflammation, which may explain prolonged anosmia in patients with long COVID
Aliphatic amines and carboxylic acid substrates produce amides and AMP under the action of ATP-dependent amide bond synthetase
ROS are present in cells and tissues at low but measurable concentration which is determined by the balance between the rate of production versus the clearance by different antioxidant enzymes (SOD, glutathione peroxidase and catalase) and compounds (glutathione, ascorbate, -tocopherol, -carotene).12 A complex functional modulation of several proteins occurs upon cellular oxidative stress.13-15 In particular, this is accomplished through modification of proteins since several aminoacids, such as Tryptophan, Tyrosine, Histidine and particularly Cysteine, are direct targets of ROS.16 ROS-mediated protein modification can affect both protein structure and function and protein stability
4.4 Relationship between GSH modulation and cognitive performance In young adults, an increase of GSH in IFC and IPL (from resting state MRS to fMRS) predicted a better cognitive performance
