Primary role of adipokinetic hormone in the formation of low density lipophorin in locusts.

Journal of Lipid Research, 1990
It was demonstrated that the primary action of adipokinetic hormone (AKH) is to stimulate calcium ion uptake into the fat body cell, subsequently causing the formation of diacylglycerol from triacylglycerol. Furthermore, it was also shown that AKH is not

Table_1_Effect of calcium ionophore (A23187) on embryo development and its safety in PGT cycles.docx [PDF]

, 2023
BackgroundIntracytoplasmic sperm injection (ICSI) has tremendous advantages for resolving the problem of male infertility. However, ICSI fertilization can fail in some patients because of various reasons, primarily because of the failure of oocyte ...

Peritoneal fluid modulates the sperm acrosomal exocytosis induced by N-acetylglucosaminyl neoglycoprotein

Brazilian Journal of Medical and Biological Research, 1999
The effect of peritoneal fluid (PF) on the human sperm acrosome reaction (AR) was tested. Sperm was pre-incubated with PF and the AR was induced by calcium ionophore A23187 and a neoglycoprotein bearing N-acetylglycosamine residues (NGP).

Characterization of ionomycin as a calcium ionophore.

Journal of Biological Chemistry, 1978
The ionophorous properties of a new antibiotic, ionomycin, have been studied. It was found that the antibiotic is capable of extracting calcium ion from the bulk of an aqueous phase into an organic phase. The antibiotic also acts as a mobile ion carrier to transport the cation across a solvent barrier.

Roscovitine in combination with calcium ionophore induces oocyte activation through reduction of M-phase promoting factor activity in mice [PDF]

, 2011
SummaryThe aim of the present study was to determine oocyte activation and change in M-phase promoting factor (MPF) activity induced by treatment with calcium ionophore and roscovitine in comparison with those induced by treatment with roscovitine alone ...

Rediscovering Sodium Ionophores as Selective Agents for Lithium Recognition and Extraction

Angewandte Chemie, EarlyView.
Long‐classified sodium ionophores unexpectedly prefer lithium and act as efficient extractants in solid–liquid extraction (SLE). Readily prepared from catechol and haloacetamides, these hosts recover hydrated LiCl from multicomponent salt mixtures via a hydration‐assisted O···Li+ binding mode, enabling scalable lithium separation with Li/Na, Li/K, and ...

Decreased prostaglandin production by cholesterol-rich macrophages.

Journal of Lipid Research, 1989
The regulation of prostaglandin production by macrophages enriched in cholesterol was examined. Mouse peritoneal macrophages were incubated for 18 h with 25 micrograms/ml of human acetyl-LDL (low density lipoprotein) and trace amounts of labeled ...
