Applications of Electrophotocatalysis in C-H Functionalization of Organic Molecules.

Electrophotocatalysis (EPC) has evolved as a new scientific discipline around the boundary of highly active fields: electrochemistry and photocatalysis. EPC allows us to combine the energy of light and electric potential to activate previously inaccessible compounds via single-electron transfer (SET). Herein, we review the most essential applications of EPC to the C-H functionalization of molecules.

Molecular Hydrogen: Is This a Viable New Treatment for Plants in the UK?

Despite being trialed in other regions of the world, the use of molecular hydrogen (H) for enhanced plant growth and the postharvest storage of crops has yet to be widely accepted in the UK. The evidence that the treatment of plants and plant products with H alleviates plant stress and slows crop senescence continues to grow. Many of these effects appear to be mediated by the alteration of the antioxidant capacity of plant cells.

Molecular hydrogen as an adjuvant therapy may be associated with increased oxygen saturation and improved exercise tolerance in a COVID-19 patient.

Administration of molecular hydrogen dissolved in water to patient with COVID-19-like symptoms may improve oxygen levels and exercise capacity.

An H2-infused, nitric oxide-producing functional beverage as a neuroprotective agent for TBIs and concussions.

Traumatic brain injuries (TBIs) are a leading cause of death and disability. Sports-related TBIs are estimated to be more than several million per year. The pathophysiology of TBIs involves high levels of inflammation, oxidative stress, dysregulation of ion homeostasis, mitochondrial dysfunction, and apoptosis.

Molecular hydrogen is comparable to sulfasalazine as a treatment for DSS-induced colitis in mice.

Colitis is an inflammatory condition of the bowels associated with abdominal pain, diarrhea, fatigue, and fever. Its etiology is multifactorial but related to the overproduction of inflammatory and oxidative mediators. There is currently no cure for this disease, and drugs used to manage it often have deleterious side effects.

Alterations in myocardial connexin-43 and matrix metalloproteinase-2 signaling in response to pregnancy and oxygen deprivation of Wistar rats: a pilot study .

Two important aspects of cardiac adaptive response to pregnancy have been studied in normal as well as hypoxic conditions: (1) intercellular signaling mediated by myocardial connexin-43 (Cx43) that is crucial to synchronize heart function; (2) extracellular signaling mediated by matrix metalloproteinase-2 (MMP-2) that is an early marker of extracellular matrix remodeling. Myocardial Cx43 distribution and functional capillary density were determined as well. Hypoxia was induced by exposure of rats to 10.

Polypeptides synthesized in rabbit cells infected with murine herpesvirus (MHV): a comparison of proteins specified by various MHV strains.

Polypeptides synthesized in rabbit embryo fibroblasts (REF) infected with six isolates of murine herpesvirus (MHV) coming from different localities in CSFR were compared by electrophoresis (SDS-PAGE). Altogether 28 virus-coded polypeptides with apparent molecular weights ranging from 240 kD to 16 kD were identified. While isolates MHV-60, MHV-72, and MHV-76 had identical polypeptide profiles, the isolates MHV-68 and MHV-78 lacked a polypeptide with apparent molecular weight of 46 kD, the rest of polypeptides being identical as well.
