In this study, we present an innovation method to synthesize ZnO nanoparticles colloidal solution by Zn2+ precipitation, and using COS and COS-I2 as a stabilizer agent to replace high molecular weight chitosan in previous studies. [17,18,24] It was favorable due to COS with small Mw did not precipitate at alkaline pH. Thus, ZnO/COS and ZnO/COS-I2 composite nanomaterials were prepared in this work will be oriented to use as antimicrobial agrochemicals, and post-harvest preservation.

Treatment of hydrogen peroxide with a polymer-supported hypervalent iodine compound, poly[4-diacetoxyiodo] styrene (PDAIS), generates singlet molecular oxygen ( 1 O2). Singlet oxygen generation was proved by trapping with typical organic compounds such as conjugated dienes, aromatic dienes, and electron-rich alkene. When compared to monomer analogue, the use of PDAIS in peroxidation of substrates gave slightly better yields (45%–96%). Regeneration and reuse of PDAIS showed similar activity. The mechanism underlying generation of singlet oxygen and reaction scope was examined.

Cancer stem cells (CSC) are characterized by deregulated self-renewal, tumorigenicity, metastatic potential, aberrant stemness signaling pathways, resistance to conventional therapy, and the ability to give rise to a progeny of proliferating cells that constitute the bulk of tumors.

The immune system is a crucial component in cancer progression or regression. Molecular iodine (I2) exerts significant antineoplastic effects, acting as a differentiation inductor and immune modulator, but its effects in antitumor immune response are not elucidated.

The in vitro activities of purified potato starch branching enzyme (SBE) I and II expressed in Escherichia coli were compared using several assay methods. With the starch– iodine method, it was found that SBE I was more active than SBE II on an amylose substrate, whereas SBE II was more active than SBE I on an amylopectin substrate. Both enzymes were stimulated by the presence of phosphate.

Recent reductions in cancer mortality are due in part to risk reduction behaviors like smoking cessation and more strongly to early detection of cancer coupled with appropriate therapy. Yet, there are no validated molecular biomarker tests for the early detection of any cancer (see Table I). Among the list of Food and Drug Administration (FDA)-approved biomarkers, none have been approved for cancer early detection and screening.

Specific micronutrient deficiencies may affect maternal and foetal health. Iodine deficiency during pregnancy may cause foetal brain damage and mental retardation in infants. Vitamin A deficiency increases the risk in pregnant women of infection and anaemia, may cause blindness during pregnancy and early lactation, and has been associated to an elevated risk of HIV mother-to-child transmission. Folate deficiency may cause severe foetal neural tube defects like anencephaly and spina bifida.
