General description

Sodium chloride (NaCl) is a colorless solid and its crystals belong to the cubic crystal system. It is widely employed preservative for meat, vegetable and fish products. NaCl is a useful precursor for the production of sodium and chlorine containing compounds. Its effect on the growth of salmonellae (mixed inoculum of Salmonella thompson, S. stanley and S. infantis) has been investigated.

Application

Sodium chloride was used in the isolation medium along with other constituents, prepared for incubating bone-marrow cells, during the isolation and expansion of hBM-MSCs (human bone-marrow mesenchymal stem cells).

Alcohol is one of the leading threats to health worldwide. Craving for alcohol makes abstinence a difficult challenge by maintaining alcohol dependence. Many studies suppose the hypothalamic-pituitary-adrenal axis, especially the proopiomelanocortin (POMC)-derived neuropeptides, to mediate craving during withdrawal in alcohol

The modification of the inner nanopore wall by polymers is currently used to change the specific properties of the nanosystem. Among them, the polyethylene glycol (PEG) is the most used to prevent the fouling and ensure the wettability. However, its
