TL;DR: Variable temperature magnetic susceptibility and magnetization studies show that all complexes possess an S = 4 ground-state.
Abstract: The reaction of Mn(ClO4)2·6H2O with Ph-saoH2 (Ph-saoH2 = 2-hydroxybenzophenone oxime) in MeCN in the presence of sodium propionate forms the complex [MnIII6O2(Ph-sao)6(prop)2(MeCN)2]·5.27MeCN (1·5.27MeCN) (prop = propionate). Repeating the same reaction in EtOH produces the complex [MnIII6O2(Ph-sao)6(prop)2(EtOH)4] (2). Complexes 1 and 2 may be considered as structural isomers, since they display the same metallic core but different coordination modes of the propionate ligands; bridging in 1 and terminal in 2. Performing similar reactions and switching from sodium propionate to sodium adamantane-carboxylate (NaO2C-ada) and sodium pivalate (Napiv) in the presence of NEt4OH yields the complexes [MnIII6O2(Ph-sao)6(O2C-ada)2(MeOH)4] (3) and [MnIII6O2(Ph-sao)6(piv)2(EtOH)4]·0.5Et2O (4·0.5Et2O), respectively. All four complexes contain the same {MnIII3O(Ph-sao)3} building block. Variable temperature magnetic susceptibility and magnetization studies show that all complexes possess an S = 4 ground-state.

TL;DR: The inhibition of floral induction by auxins may not be dependent on their effect on the cytoplasmic pH, and the promotion of flowering by bases was obtained even when only the cotyledons had been treated.
Abstract: Permeant weak acids and auxins have been shown to reduce the cytosplasmic pH in several systems. Lactic, citric, formic, butyric, salicylic, parahydroxybenzoic, propionic acid, and sodium propionate inhibited the flowering response of Pharbitis nil seedlings when applied immediately before an inductive dark period. The acidic auxins IAA, indolebutyric, and α-naphtaleneacetic acid, as well as the nonacidic auxin α-naphtaleneaceteamid, also inhibited the flowering response. Inhibition was generally more pronounced with a 12-hour than with a 16-hour dark period. Salicylic acid and sodium propionate shifted the response curve of the dark period by about 2 hours. Salicyclic acid, sodium propionate, and indolebutyric acid were inhibitory when applied during the first few hours of the dark period. The permeant weak bases NH4Cl, procaine, and trisodium citrate enhanced the flowering response. NH4Cl reduced the length of the critical dark period. The inhibition of flowering by acids and auxins as well as the promotion of flowering by bases was obtained even when only the cotyledons had been treated. The inhibition of floral induction by auxins may not be dependent on their effect on the cytoplasmic pH.

TL;DR: The mechanism and role of two 3-hydroxyvalerate (3-HV) inducing substrates on the production of PHBV with high, 80%, 3- HV content were evaluated and it was found that levulinic acid contributes to biomass and bio-polymer content enhancement, whereas sodium propionate mainly contributes to 3-Hv enhancement.

TL;DR: Treatment of a cloned mastocytoma P-815 cell line with 1 mM-sodium n-butyrate for 40h induced prostaglandin synthase activity and arrested cell growth, and selective induction of fatty acid cyclo-oxygenase activity by sodium n- butyrate was suggested.
Abstract: Treatment of a cloned mastocytoma P-815 cell line (2-E-6) with 1 mM-sodium n-butyrate for 40h induced prostaglandin synthase activity and arrested cell growth. The induction of enzyme activity by n-butyrate was not associated with suppression of DNA synthesis, since hydroxyurea had no effect on prostaglandin synthase induction. The effect of sodium n-butyrate was reversible. Experiments with cycloheximide and actinomycin D showed that the induction of prostaglandin synthase activity involved synthesis de novo of protein and RNA. The time of half-maximal induction of the newly synthesized RNA for prostaglandin synthase activity was estimated as about 15h, which is similar to the generation time of the cells. Selective induction of fatty acid cyclo-oxygenase activity by sodium n-butyrate was suggested by the following two pieces of experimental evidence. (1) There was no significant difference between treated and untreated cells in the activities of radioactive prostaglandin H2 conversion into individual prostaglandins. (2) The incorporation of [3H]acetylsalicylic acid into the fraction equivalent to protein of mol.wt. approx. 75000 of sodium n-butyrate-treated cells was higher than that of untreated cells, on analysis of cell particulate fraction by sodium dodecyl sulphate/polyacrylamide-gel electrophoresis. A high concentration (5 mM) of sodium propionate also induced prostaglandin synthesis, but other short-chain fatty acids, such as isobutyrate and sodium acetate, had no effect.
