“The exposure assessment was carried out for Staphylococcus aureus in kimbab by predicting growth of S. aureus and the production of enterotoxin using Food MicroModel (R) program. Environmental parameters selected were pH 5.5, Aw 0.999, and storage temperatures in the range of 10 to 30 degrees C. It was predicted that 6.3 hr could be a critical time for enterotoxin production while kimbab was stored at 30 degrees C. Mild case scenario JQ-EZ-05 concentration analysis showed that enterotoxin could not be produced if kimbab was kept at 10 degrees C during preparation
and distribution and then left at 25 degrees C for 4 hr before consumption. In the worst case scenario, the keeping time at 25 degrees C was assumed to be 7.0 hr. The level of S. aureus in the worst case was predicted to be 6.8×10(6) CFU/g which is lower than the critical level (7.8×10(6) CFU/g) for toxin production.”
“1-acetoxy-5, 7-dihydroxycassa-11,13(15)-diene-16,12-lactone, a new cassane-type diterpene was isolated from Caesalpinia crista. The structure of this compound was elucidated by analysis Selleck PF 00299804 of NMR spectra, and the relative configuration was established by NOE experiment. The new compound was evaluated for antitumour activity against T47D, DU145 and showed significant inhibitory activities.”
“Shifted hysteresis loops characteristic of the exchange bias effect between a ferromagnet and an antiferromagnet are demonstrated in structures
formed by a 2.5 nm Cr layer deposited on top of an array of Fe nanoislands (Cr/Fe-nanoislands). This effect evidences the persistence of antiferromagnetic (AF) order for Cr layers much thinner than the thickness reported in the literature. The field shift measured is found to increase for the smallest island sizes, which can be related with the enhancement of the Fe-nanoisland surface to
volume ratio. The comparative study between superconducting proximity effects in Nb/Cr/Fe-nanoislands and Nb/normal metal/Fe-nanoisland https://www.selleckchem.com/products/BafilomycinA1.html hybrids (where the normal metals used are Al and Pt) confirms the presence of AF order in the 2.5 nm Cr spacer layer. A much shorter penetration depth of the Cooper pairs into the AF Cr layers than in the normal metal Pt and Al spacer layers is deduced.”
“Essential oils of anise, bastard cardamom, cinnamon, dill, mace, zedoary, prikhom, and bitter ginger were determined for their antimicrobial and antioxidant activities. Of all, cinnamon oil had the highest antibacterial activity. The most sensitive bacteria was Bacillus cereus (0.5mg/mL minimum inhibitory concentration, MIC). Anise, cinnamon, dill, and prikhom exhibited strong antifungal activity against Rhodotorula glutinis, Aspergillus ochraceus, and Fusarium moniliforme. Two oil combinations: i) cinnamon and mace oils and ii) cinnamon and prikhom oils showed a synergistic effect against Staphylococcus aureus, Pseudomonas fluorescens, and Salmonella Rissen (0.
