Phosphine Sorption on Paddy Rice: Effects on Fumigation and Grain Quality Parameters.

During storage, infestation by insect pests occurs, causing quantitative and qualitative losses in grains, which requires the control of these insects with phosphine gas. Rice husk has a high phosphine adsorption capacity, influencing the gas concentration during fumigation and potentially leading to inefficient fumigation. Additionally, the high sorption of rice husk results in a higher residue of phosphine in the grain.

Myonuclear position and blood vessel organization during skeletal muscle postnatal development.

Skeletal muscle development is a complex process involving myoblast fusion to generate multinucleated fibers. Myonuclei first align in the center of the myotubes before migrating to the periphery of the myofiber. Blood vessels (BVs) are important contributors to the correct development of skeletal muscle, and myonuclei are found next to BVs in adult muscle.

Identification of human circulating factors following remote ischemic conditioning (RIC): Potential impact on stroke.

Remote ischemic conditioning (RIC) is a procedure consisting of short cycles of ischemia applied in a limb that activates endogenous protection in distant organs, such as the brain. Despite the promising outcomes of RIC, the biochemical factors governing inter-organ communication remain largely unexplored, particularly in humans. A pilot study on 20 healthy humans was performed to identify potential circulating biochemical factors involved in RIC signalling.

Anticancer potential of NSAID-derived tris(pyrazolyl)methane ligands in iron(II) sandwich complexes.

Tris(pyrazolyl)methane (tpm), 2,2,2-tris(pyrazolyl)ethanol (tpmOH) and its esterification derivatives with ibuprofen and flurbiprofen (tpmIBU and tpmFLU) were used as ligands to obtain complexes of the type [Fe(tpm)]Cl (1-4). The tpmIBU and tpmFLU ligands and corresponding complexes 3 and 4 were characterized by IR and multinuclear NMR spectroscopy, and the structure of tpmIBU was elucidated by single crystal X-ray diffraction.
