Early intervention using dietary supplements may be effective in alleviating cognitive impairment among individuals with mild cognitive impairment (MCI). This study investigated the efficacy and safety of Lactobacillus plantarum C29-fermented soybean (DW2009) as a nutritional supplement for cognitive enhancement. One hundred individuals with MCI were randomly assigned to take DW2009 (800 mg/day, n = 50) or placebo (800 mg/day, n = 50) for 12 weeks. The primary outcome measure was change in the composite score of cognitive functions related to memory and attention, measured by computerized neurocognitive function tests. Associations between changes in serum brain-derived neurotrophic factor (BDNF) levels and cognitive performance for each treatment group were evaluated. Compared to the placebo group, the DW2009 group showed greater improvements in the combined cognitive functions (z = 2.36, p for interaction = 0.02), especially in the attention domain (z = 2.34, p for interaction = 0.02). Cognitive improvement was associated with increased serum BDNF levels after consumption of DW2009 (t = 2.83, p = 0.007). The results of this clinical trial suggest that DW2009 can be safely administered to enhance cognitive function in individuals with MCI. Increased serum BDNF levels after administering DW2009 may provide preliminary insight into the underlying effects of cognitive improvement, which suggests the importance of the gut-brain axis in ameliorating cognitive deficits in MCI.

5. The ECF translocation across the atrial wall was not influenced by changes in external Ca2" but was suppressed by low temperature.6. Dynamic changes in the ECS of the atrium were observed in response to atrial distension and reduction. The ECS of the atrium increased on distension and decreased on reduction of atrial distension.7. Reduction in atrial distension resulted in an increase in the secretion of immunoreactive atrial natriuretic peptide (ANP) which coincided with an increase in the translocation of the ECF. The secretion of immunoreactive ANP was a function of the translocation of the ECF.8. It is suggested that atrial stretch and release may play a role in driving fluid flow within the interstitium and fluid translocation out of the interstitium. This fluid movement presumably leads to convective transport of released ANP into the atrial lumen.

Three new flavonoid glycosides ( 1- 3), 11-hydroxyhainanolidol ( 4), and a new dibenzylbutyrolactone lignan glycoside ( 5) were isolated from the aerial parts of Cephalotaxus koreana Nakai, along with 19 known flavonoids. The structures of the new compounds were elucidated using spectroscopic evidence, primarily NMR and MS. Twenty-four compounds were isolated, and among these isoscutellarein 5-O-beta-D-glucopyranoside ( 3), apigenin ( 6), kaempferol 3-O-alpha-L-rhamnopyranosyl(1'''-->6'')-beta-D-glucopyranoside ( 7), tamarixetin 3-O-alpha-L-rhamnopyranosyl(1'''-->6'')-beta-D-glucopyranoside ( 8), quercetin 3-O-[6''-O-acetyl]-beta-D-glucopyranoside ( 9), and quercetin 3-O-alpha-L-rhamnopyranoside ( 10) showed significant inhibitory activities against osteoclast differentiation at concentrations of 0.1 and 1.0 microg/mL.
