Show moreLeafy greens have been associated with multiple outbreaks of Escherichia coli O157:H7 (EC) infection in recent years. More information is needed on EC survival during post-harvest processes, and our study aimed at evaluating survival in packaged spinach after treatment of cells with sodium hypochlorite. A green fluorescent protein-expressing strain of EC was exposed to sodium hypochlorite in two different ways, i.e., exposed in solution or on the spinach leaves. For exposure in the solution, EC was inoculated into 1 ppm sodium hypochlorite for 30 seconds, then the cells were inoculated onto the spinach leaves. For exposure on the spinach leaves, EC was first inoculated onto leaves; then the inoculated spinach leaves were dipped into 100 ppm sodium hypochlorite. After inoculation, the spinach was packaged to obtain high-oxygen (20%O2/3%CO2) and low-oxygen (0%O2/15%CO2) atmospheres, respectively. The packages were stored at 4°C or 15°C, and EC populations were quantified at six sampling points during 14 days of storage. The data were analyzed by DMFit and Microfit to demonstrate the growth curve and kinetics. In general, there were no apparent differences in EC behavior between the chlorine treated and control groups for most of the conditions. However, in certain conditions, the chlorine-treated cells showed a faster decrease and/or slower increase in population than the control packages. Generally, low temperature and high oxygen conditions led to lower survival than high temperature and low oxygen. For EC exposed in solution, the EC population showed a greater reduction and faster decrease in the high-oxygen than low-oxygen packages at 4°C. At 15°C, the lowoxygen condition resulted in a faster growth rate (+0.43 log CFU/ml/day) than high oxygen packages (+0.17 log CFU/ml/day). Also, in the 4°C high-oxygen condition, the chlorine-treated cells showed a greater population decrease (-0.95 log CFU/ml) than the control groups (-0.57 log CFU/ml). For EC exposed on the spinach, the low-oxygen packages showed greater population levels and faster growth rates compared to the highoxygen packages at 15°C. At 4°C, chlorine treated groups and control groups showed no apparent differences for both low- and high- oxygen packages. At 15°C, the chlorine treated packages showed less increase in population (+0.79 log CFU/ml) than the controls (+1.58 log CFU/ml) in low-oxygen; and the control groups increased at a faster growth rate (+0.57 log CFU/ml/day) than the chlorine treated ones (+0.25 log CFU/ml/day).

Show moreThe indirect flight muscles (IFM) of insects are nature’s versatile engines highly specialized to produce power for flight. Myosin, the motor protein, plays an important role in this process, supporting the rapid wingbeat frequency and converting chemical energy into mechanical force. A novel efficient protocol for preparing functional myosin from Manduca sexta flight muscle is described in this study. We tested the biochemical properties of myosin from the dorsal subunit and ventral subunit of the dominant flight muscle. High salt solubilization and low salt precipitation was used to extract myosin from the homogenate of moth split thorax muscles since low ionic strength allows filament formation and precipitation of myosin while high ionic strength helps myosin solubility. Coomassie Blue stained 10% SDS PAGE analysis showed the purity was 50% and the result was confirmed by western blot with anti-myosin antibody MAC 147. This revealed the final pellet of purification was myosin and was of moderate purity and homogeneity, showing that this method was feasible for isolating myosin from this species. The focus of this study was to compare the catalytic efficiency of extracted ventral DLM1 myosin and dorsal DLM1 myosin in vitro, as myosin was the dominant catalytic protein which hydrolyze ATP to utilize energy in muscle contraction. The rate of an identical ATP hydrolysis reaction was measured catalyzed by myosin extracted from DLM1D and DLM1V, and the activation energy (Ea) was calculated using Arrhenius equation. The reaction catalyzed by dorsal myosin exhibited higher Ea than that catalyzed by ventral myosin, which meant a lower catalytic efficiency of DLM1D myosin. This indicated catalytic heterogeneity of DLM1D and DLM1V myosin in a single muscle. Additionally, a significant within muscle Ea difference of ATP hydrolysis could be partially responsible for the known temperature gradient, within the DLM1 of Manduca demonstrated previously(Nicole T George & Daniel, 2011), considering that the hydrolysis of ATP is responsible for the heat generated during muscle contraction as well as muscle force and lengthening.

Show moreBased on Institute of Medicine recommendations, excessive gestational weight gain is a widely documented problem. At present, the relation between gestational weight gain and food cravings in pregnancy is largely unknown. This study sought to assess associations between gestational food cravings and the following adverse outcomes: excessive gestational weight gain, depressed mood, disordered eating attitudes and behaviors, and body dissatisfaction. A community sample of 74 pregnant women completed self-report questionnaires. Appearance evaluation and body areas satisfaction, two indices of body dissatisfaction, were inversely correlated with disordered eating attitudes and behaviors, current body mass index (BMI), and pre-pregnancy BMI. Depression was significantly related to disordered eating attitudes and behaviors and to one index of body dissatisfaction. Excessive gestational weight gain was not related to the presence of food cravings or to consumption of craved foods. Trait-level food cravings were significantly related to disordered eating attitudes and behaviors, and disordered eating attitude scores differed significantly based on the presence of food cravings. Moderation analyses revealed that change in BMI moderated the relation between the presence of gestational food cravings and disordered eating attitudes and behaviors after accounting for relevant covariates, such that there was a stronger association between gestational food cravings and disordered eating attitudes in women with a greater change in BMI compared to women who experienced a low change in BMI. For those with a smaller change in BMI, disordered eating did not differ based on the endorsement of food cravings. However, for those with a large change in BMI, participants who reported the presence of food cravings endorsed more disordered eating as compared to those who did not report the presence of food cravings. Food cravings and gestational weight gain should be closely monitored as they may exacerbate underlying disordered eating attitudes or behaviors.
