High-dose hypofractionated SBRT and SRS indirectly kills substantial fractions of tumor cells via causing vascular damage. The LQ formula may work well for certain clinical cases of SBRT and SRS when the indirect/additional tumor cell death secondary to vascular damage is small. However, when the indirect cell death is extensive, the LQ model will underestimate the clinical outcome of SBRT and SRS.Peroxyzymes simply use H2O2 as a cosubstrate to oxidize a broad range of inert C-H bonds. The lability of many peroxyzymes against H2O2 can be addressed by a controlled supply of H2O2, ideally in situ. Here, we report a simple, robust, and water-soluble anthraquinone sulfonate (SAS) as a promising organophotocatalyst to drive both haloperoxidase-catalyzed halogenation and peroxygenase-catalyzed oxyfunctionalization reactions. Simple alcohols, methanol in particular, can be used both as a cosolvent and an electron donor for H2O2 generation. Tamoxifen ic50 Very promising turnover numbers for the biocatalysts of up to 318 000 have been achieved.This study investigated the antibacterial and in vitro antidementia effects of aronia (Aronia melanocarpa) leaf extracts from 3 cultivars (Nero, Viking, and McKenzie) collected at three different stages of maturity (young, harvest, and old). Bacillus cereus was susceptible to the old leaves of cultivars McKenzie and Nero, whereas Escherichia coli O157H7, Salmonella Typhimurium, and Listeria innocua were not inhibited by any of the extracts. Growth of B. cereus was inhibited by cv. McKenzie, resulting in increased lag time, whereas Nero had both an inhibitory and an inactivation effect. Except for cv. Viking at harvest stage, the acetylcholinesterase and butyrylcholinesterase inhibitory activity of aronia leaf extracts were about 60-70 and 70-80%, respectively. Therefore, aronia leaf is a natural resource with a potentially potent antidementia effect, besides antibacterial activity.This study was undertaken to improve the detection accuracy for coliform bacteria, by analyzing biochemical properties of false positive and false negative colonies isolated from two dry rehydratable film methods, 3 M™ Petrifilm™ E. coli/Coliform count (PCC) and MC-Media Pad coliform count (MCC). The detection accuracy of PCC and MCC was determined to be 99.4% and 97.9%, respectively, with the detection error being 0.6% and 2.1%, respectively. False positive colonies (red colony without gas) on PCC were identified as Hafnia alvei and Enterobacter cloacae. All false positive colonies on MCC were identified as Aeromonas caviae; this organism gives a positive oxidase test, whereas coliform bacteria are oxidase negative. In conclusion, we propose that for improving detection accuracy of coliform bacteria, the incubation time of PCC should be modified and increased from 24 h to 48 h, and the oxidase test of MCC isolates should be included in the Korea Food Code.Aluminum based reflective nanolens arrays were developed via a series of aluminum electropolishing and anodization steps with subsequent selective dissolution of anodic aluminum oxide (AAO). The diameter of nanolenses (d) on arrays can be controlled by altering electrolytes and voltages used for aluminum anodization. The d values of arrays produced by anodization in 0.3 M oxalic acid at 40, 60, and 80 V, and in 1.0 M phosphoric acid at 100, 110, and 120 V were 71.94, 121.90, and 161.53 nm, and 220.16, 252.06, and 274.78 nm, respectively. The effectiveness of UV (254 nm) inactivation of Escherichia coli O157H7 and Listeria monocytogenes at concentrations of 5-6 log CFU/mL in water and in a 10% (w/v) sucrose solution was improved using a nanolens array having a d value of 252.06 nm.This research aimed to evaluate the effect of acid stress on the expression of stress regulator (grxB and rpoS) and virulence (ompA, hfq, and cpa) genes of Cronobacter sakazakii Yrt2a. The results showed that C. sakazakii Yrt2a experienced decrease in number during acid stress and was no longer culturable 90 min post exposure to pH 3.0. During acid stress, the expression of grxB, rpoS, ompA, cpa and hfq was upregulated by 2.15; 2.19; 1.55; 1.1 and 1.41 log, respectively. However, all genes expression was downregulated when the bacteria entered the unculturable state. The expression of gene grxB, rpoS, ompA, cpa decreased to 1.04; 0.37; 0.84 and 1.71 log, respectively; while hfq gene expression reached a level lower than that of control. This research implies a supposition that during acid stress, C. sakazakii was capable of maintaining its culturability and pathogenicity until they are no longer culturable.This study was conducted to evaluate the storage conditions of matcha (Camellia sinensis) according to temperature during 2 months. The moisture content of matcha tend to decrease with increasing temperature. To evaluate the brightness and green value of matcha, changes in L* and G* values were examined. These values decreased with increasing temperature and time. Total phenolic content and total flavonoid content also decreased with increasing temperature and time. ABTS and DPPH radical scavenging activities decreased with the increase in storage temperature and time. The content of catechins such as epicatechin, epigallocatechin, epicatechin gallate and epigallocatechin gallate showed a tendency to decrease gradually according to the storage temperature and time. Also, caffeine and rutin content in matcha significantly decreased according to storage temperature and time. This study could be used as basic data to determine optimal storage conditions by measuring physiological changes according to the temperature conditions of matcha.This study was designed to evaluate the antioxidant activity of methanol extract of Averrhoa carambolla Linn. leaves (MELA) using DPPH· and ABTS·+ free radical scavenging assays whereas its antineoplastic effect against Ehrlich ascites carcinoma (EAC) was assed using viable cell count, life span, body weight gain and hematological parameters of experimental mice. Results showed that rich phenolic and flavonoid content of MELA had moderate dose dependent free radical scavenging activity (IC50 62.0 μg/mL for DPPH· and 6.0 μg/mL for ABTS·+). In vivo antineoplastic assay, MELA significantly (P  less then  0.05) decreased viable cells and body weight gain, increased the survival time and restored altered hematological profiles of cancer cell bearing mice. Fluorescence microscopic view of EAC cells derived from MELA-treated group showed apoptotic characteristics and this observation was also supported by overexpression of pro-apoptotic genes coding p53 and Bax proteins in treated cancer cells. The anti-apoptotic genes coding Bcl-2 protein was also absent in treated EAC cells as compared with the control.
