The effects of combined dietary probiotics Lactococcus lactis BFE920 and Lactobacillus plantarum FGL0001 on innate immunity and disease resistance in olive flounder (Paralichthys olivaceus).

The effects of a dietary probiotic mixture containing Lactococcus (Lc.) lactis BFE920 isolated from bean sprout and autochthonous Lactobacillus (Lb.) plantarum FGL0001 originally isolated from the hindgut of olive flounder (Paralichthys olivaceus) were investigated for the purpose of improving the probiotic effects of Lc.

[The variation of hepatic duct confluence and asymptomatic common bile duct stone with routine intraoperative cholangiogram during laparoscopic cholecystectomy].

Background/aims: Intraoperative cholangiogram (IOC) during laparoscopic cholecystectomy (LC) has been used to evaluate bile duct stone. But, the routine use of IOC remains controversial. With routine IOC during LC, we reviewed the variation of hepatic duct confluence and try to suggest the diagnostic criteria of asymptomatic common bile duct (CBD) stone.

Activity-dependent potentiation of large dense-core vesicle release modulated by mitogen-activated protein kinase/extracellularly regulated kinase signaling.

Large dense-core vesicles (LDCVs), containing neuropeptides, hormones, and amines, play a crucial role in the activation of the sympathetic nervous system and synaptic modulation. In some secretory cells, LDCVs show activity-dependent potentiation (ADP), which represents enhancement of subsequent exocytosis, compared with the previous one. Here we report the signaling mechanism involved in ADP of LDCV release.

Dual roles of P2 purinergic receptors in insulin-stimulated leptin production and lipolysis in differentiated rat white adipocytes.

ATP is co-localized with norepinephrine at the sympathetic nerve terminals and may be released simultaneously upon neuronal stimulation, which results in activation of purinergic receptors. To examine whether leptin synthesis and lipolysis are influenced by P2 purinergic receptor activation, the effects of ATP and other nucleotides on leptin secretion and glycerol release have been investigated in differentiated rat white adipocytes. Firstly, insulin-induced leptin secretion was inhibited by nucleotide treatment with the following efficacy order: 3'-O-(4-benzoyl)benzoyl ATP (BzATP) > ATP >> UTP.

Phytoestrogen cimicifugoside-mediated inhibition of catecholamine secretion by blocking nicotinic acetylcholine receptor in bovine adrenal chromaffin cells.

We investigated the effect of the phytoestrogen cimicifugoside, one of the pharmacologically active ingredients of the medicinal plant Cimicifuga racemosa (black cohosh) that has been used to treat many kinds of neuronal and menopausal symptoms, such as arthritis, menopausal depression, and nerve pain. Cimicifugoside inhibited calcium increase induced by 1,1-dimethyl-4-phenylpiperazinium iodide (DMPP), a nicotinic acetylcholine receptor (nAChR) agonist in bovine adrenal chromaffin cells with a half-maximal inhibitory concentration (IC(50)) of 18 +/- 2 microM. In contrast, cimicifugoside did not affect the calcium increases evoked by high K(+), veratridine, and bradykinin.
