Recent studies have reported that meal timing may play an important role in weight regulation, however it is unknown whether the timing of meals is related to the amount of weight loss. This study aimed to examine the relationship between indices of meal timing and weight loss during weight loss intervention in adults. A 12-week weight loss support program was conducted for 97 adults (age: 47.6 ± 8.3 years, BMI: 25.4 ± 3.7 kg/m2). After the program, body weight decreased by −3.0 ± 2.7%. Only the start of the eating window was positively correlated with the weight change rate in both sexes (men: r = 0.321, p = 0.022; women: r = 0.360, p = 0.014). The participants were divided into two groups based on the start of the eating window as follows: the early group (6:48 ± 0:21 AM) and the late group (8:11 ± 1:05 AM). The weight loss rate in the early group was significantly higher (−3.8 ± 2.7%) than that in the late group (−2.2 ± 2.5%). The present results showed that the start of the early eating window was associated with weight loss and suggested paying attention to meal timing when doing weight loss.

Benzoxazine resin exhibits excellent properties and is widely used in many fields. Herein, the synthesis of a novel compound, the bis(2,4-dihydro-2 H-3-(4- N-maleimido)phenyl-1,3-benzoxazinyl)biphenyl (BMIPBB), has been reported, which was synthesized by reacting N-(4-aminophenyl)maleimide (APMI), formaldehyde, and 4,4’-dihydroxybiphenyl. 1,3,5-three(4-(maleimido)phenyl)-1,3,5-triazine (TMIPT) was formed as an intermediate during the reaction. The proton nuclear magnetic resonance (1H-NMR) and Fourier transform-infrared (FTIR) spectroscopy experiments were conducted to determine the structure of BMIPBB. BMIPBB was obtained as a reddish-brown solid in 40.1% yield. The thermal properties of BMIPBB were investigated using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) techniques. Analysis of the DSC curves revealed that the broad peak representing the release of curing reaction heat appeared in the temperature range of 140–330°C. The peak temperature was 242.59°C and the heat of the reaction was 393.82 J/g, indicating that the rate of the curing reaction was low and the heat of the reaction was high. Analysis of the TGA results revealed that the weight loss rate was 5% at 110°C. The monomer exhibited a significant weight loss in the range of 320–500°C. The compound lost 50% of its weight at a temperature of 427°C.

Appendicitis has always been an indication for an urgent operation, as delay is thought to lead to disease progression and therefore worse outcomes. Recent studies suggest that appendectomy can be delayed slightly without worse outcomes, however the literature is contradictory. The goal of our study was to examine the relationship between this delay to surgery and patient outcomes. We reviewed all patients that underwent an appendectomy in our institution from January 2009 to December 2010. We recorded the time of surgical diagnosis from when both the surgical consult and the CT scan (if done) were completed. The delay from surgical diagnosis to incision was measured, and patients were divided into two groups: early (≤6 hours delay) and late (>6 hours delay). Outcome measures were 30-day complication rate, length of stay, perforation rate, and laparoscopic to open conversion rate. Three hundred and seventy-seven patients had appendectomies in the study period, and 35 patients were excluded as per the exclusion criteria leaving 342 in the study: 269 (78.7%) in the early group and 73 (21.3%) in the late group. Complications occurred in 21 patients (6.1%) with no difference between the groups: 16/253 (5.9%) in the early group and 5/73 (6.8%) in the late group ( P = 0.93, χ2). The mean (± standard deviation) length of stay was 86.1 ± 67.1 hours in the early group, and 95.9 ± 73.0 hours in the late group. This difference was not significant ( P = 0.22). Delaying an appendectomy more than 6 hours, but less than 24 hours from diagnosis is safe and does not lead to worse outcomes. This can help limit the disruption to the schedules of both the surgeon and the operating room.

Kombucha is sweetened, slightly alcoholic, and lightly effervescent tea drink. Its acidity inhibits the growth of harmful bacteria. Here, we studied effect of kombucha on post-harvest preservation of pear. The Hosui pears were soaked with the kombucha for 15 minutes, and in distilled water as the control, respectively. Superoxide dismutase (SOD), peroxidase (POD), malondialdehyde (MDA), hydrogen peroxide (H2O2), proline content, electric conductivity, weight loss rate and good fruit rate in pear were measured during storage at room temperature. The results showed that the kombucha could effectively prolong the storage time of pear fruit. The fruit quality of the treated group was 1.5 times higher than that of the control pear fruit when stored at room temperature for 18 days. The weight loss rate, MDA content and electric conductivity of the treatment group were lower than those of the control group during the whole storage period, indicating that kombucha can inhibit the transformation of polysaccharides such as starch and pectin, and delay the degradation of nutrients in the fruit, resulting in a decrease in weight loss rate, inhibition of membrane lipid peroxidation, reducing MDA content, electric conductivity, maintaining cell membrane stability, delaying pear fruit senescence. Kombucha can inhibit the content of H2O2 and proline, increase the activity of POD and SOD increase the storage stability of fruits. The purpose of this study was to elucidate the physiological mechanism of post-harvest preservation of pear by kombucha. The use of kombucha can prolong the supply period of pear, increase economic benefits and expand the market of pear.   ********* In press - Online First.

In order to understand recession behavior and the amount of recession of Lu2Si2O7 in the combustion gas flow, sintered Lu2Si2O7 specimens were manufactured by hot pressing and exposed under various combustion gas flow conditions (T = 1300–1500 °C, P = 0.3 MPa, V = 150 m/s, PH2O = 27–69 kPa, t = 10h). After the exposure tests, etch pits, which are assumed to form due to volatilization of SiO2 in the grain boundary phase, were observed at the surface of specimen. The amount of Lu2SiO5 phase at the surface of specimen increased with the increase of gas temperature or water vapor partial pressure. A corresponding decrease in the amount of Lu2Si2O7 phase was observed. Furthermore, by using the average weight loss rate for exposure times of ten hours, the influence of gas temperature and water vapor partial pressure on weight loss rate was examined, and the amount of recession under gas turbine conditions was calculated.

Grazing Behaviour

In the first of two trials, 20 Hereford steers were allocated to two adjacent 1.6-ha pastures on 29 May 1996. Steers in one pasture were given no supplement, while those in the other received supplemental silage each day. All steers on each treatment grazed their allocated paddock continuously for 28 d. Steers on pasture were weighed and their behaviour was monitored periodically throughout the 4 wk of grazing. The dry matter (DM) availability at turnout (651 kg hd-1) was considered in excess to requirement, since neither availability nor sward height declined over 28 d. In spite of this, steers lost 15 kg after turnout and took 12 d to regain their initial weight. There were no treatment effects. Nutrient composition of the sward changed in accordance with advancing maturity. Percent of time observed grazing (51%) did not change over the 28-d period; however, rumination time increased from around 10 to 30%. Grazing behaviour was similar for steers on both treatments. Silage intake averaged only 1.3 kg DM hd-1d-1. In 1997, 28 yearling steers were used in a 2 × 2 factorial design to study the effect of turnout date to pasture [21 May (E) vs. 4 June (L)] and supplemental silage feeding on weight change, grazing behaviour, pasture productivity and forage quality over 28 d. The DM availability at turnout was 391 kg hd-1. Available DM and sward height declined in both early and late treatments after turnout. The early group had to be removed from the trial after 16 d when sward height dropped below 4 cm. Sward quali ty after turnout declined only for the late group. Loss of body weight (BW) and days to regain initial BW after turnout were greater for early versus late steers. Steers ate only 0.5 kg silage DM hd-1d-1, but this reduced weight loss in late steers. Cattle turned out later spent less time grazing (P < 0.001 at 5 and 14 d) but no less time ruminating. Transient weight loss associated with turnout to pasture cannot be wholly explained by behavioural patterns. Other factors, such as altered ruminal conditions, must also play an important role. Key words: Pasture, steer performance, grazing behaviour, weight change

e17504 Background: Patients with nasopharyngeal carcinoma (NPC) frequently developed the problem of malnutrition at the time of diagnosis. Chemoradiotherapy (CRT) can even worsen the situation. Therefore, nutritional intervention should be applied to prevent CRT-associated weight loss and interruption of CRT. However, it is still controversial if early nutritional intervention is beneficial to NPC patients with CRT. This study is to investigate the influence of early nutritional intervention on advanced NPC patients with CRT by evaluating the nutritional status and CRT treatment tolerance. Methods: A cohort of 78 stage III-IV nasopharyngeal carcinoma patients was divided into early (n = 46) and late (n = 32) nutrition intervention groups. The early group of patients received nutritional support at the beginning of CRT, whereas the late group received such a support until development of the side effects, like 50% required oral dietary intake or > 10% weight loss. The data were collected and statistically analyzed. Results: There was no significant difference in baseline clinical characteristics between these two groups, suggesting that no selection bias occurred. Both groups of patients had weight loss at the end of CRT and 3 months thereafter. However, at the later time point, the early group started to regain their weight, while the late group continued to lose weight. At both time points, the early group had a lower percentage of weight loss than the late group. Similar results were also obtained for BMI, albumin, and pre-albumin levels (All p< 0.05). Besides, the early group showed a lower rate of advanced mucositis, a lower percentage of patients with more than 3 days RT breaks, fewer days of RT delayed for toxicity, and a lower percentage of patients with unplanned hospitalizations (All p< 0.05). A linear correlation was also found between the percentage of weight loss and the number of days of RT delayed. Conclusions: Early nutritional intervention provides beneficial outcomes to NPC patients by maintaining their nutritional status and enhancing CRT treatment tolerance. Our results also indicated early nutrition intervention may reduce the hospital cost and improve patients’ life quality.

Aging mechanism of dam concrete under the action of freeze-thaw damage was analyzed by testing macro and micro performance. The results show that compressive, splitting tensile and flexural strengths reached 58.4%, 61.3% and 57.8% of the initial values after 150 cycles. Strength is the most sensitive indicator of freeze-thaw damage, followed by weight loss rate, relative dynamic elastic modulus and ultrasonic velocity. After freeze-thaw damage, concrete structure becomes loose, porous amount gradually increased and pore size especially over 25nm expanded. Microcracks not only exist in the hydration products, but also destroy the bubbles structure in air entrained concrete, which is the main cause of freeze-thaw damage.

Sodium compounds, Na2CO3，Na2SO4，NaCl, have been investigated with regard to their catalytic effects on chlorella pyrolysis by thermal analysis experiments. The influence of catalyst categories and dosage on chlorella pyrolysis were studied by the comparison and analysis of the TG（thermogravimetry）and DTG(derivative thermogravimetry) curves derived from tests of differential thermal balance of untreated chlorelal and chlorella mixed with three inorganic compounds of certain scale.The results show that the catalytic effect of the sodium compounds follow Na2CO3>Na2SO4>NaCl, Catalysts of Na2SO4，NaCl decreased the maximum weight loss rates while Na2CO3 increased them. And all the three additives lowered the pyrolysis temperature of chlorella，of which Na2CO3 made the highest conversion of chlorella pyrolysis. As the dosage of carbonate increased, the pyrolysis temperatures decreases and the maximum weight loss rate increases, but the conversion rate of chlorella pyrolysis decreases, considering these two factors, 5%wt is chosen as the optimal dosage of the catalysts.

In order to investigate the pyrolysis characteristics of oil shale under in the extreme conditions of high temperature and high pressure generated by the ultrasonic cavitation. The different particle size of oil shale is mixed with water in accordance with the volume ratio of 1:12, under in different ultrasonic frequency and different power, the ultrasonic radiation experiments and the thermogravimetric experiments of different samples have been done. The results show that the organic content of oil shale samples reduced after ultrasonic radiation, and the chemical reaction rate of the remaining organic matter become faster, and its reflected as the volatile separate out rate was accelerated and the changes of TG(Thermogravimetry) and DTG(Derivative Thermogravimetry) curves were steeper. Oil shale pyrolysis weight loss rate peak values and the organic matter decomposed percentage during the pyrolysis have the selective on the ultrasonic frequency, ultrasonic power and particle size of the oil shale. Oil shale pyrolysis weight loss rate peak value increased with decreasing of ultrasonic power, and the weight loss rate peak value corresponding to the peak temperature was increased with the increasing of ultrasonic frequency, and the weight loss rate peak value corresponding temperature decreased with particle size increasing of oil shale. We can draw the conclusion that the ultrasonic cavitation can decomposition organic matter of oil shale, then, we should in-depth research the ultrasonic refining shale oil.
