Nutrition Journal , 2008, DOI: 10.1186/1475-2891-7-23
Abstract: Single blind, placebo-controlled, randomized outpatient weight loss trial in 100 obese men and women comparing two isocaloric meal plans utilizing a standard MR to which was added supplementary protein or carbohydrate powder. MR was used twice daily (one meal, one snack). One additional meal was included in the meal plan designed to achieve individualized protein intakes of either 1) 2.2 g protein/kg of LBM per day [high protein diet (HP)] or 2) 1.1 g protein/kg LBM/day standard protein diet (SP). LBM was determined using bioelectrical impedance analysis (BIA). Body weight, body composition, and lipid profiles were measured at baseline and 12 weeks.Eighty-five subjects completed the study. Both HP and SP MR were well tolerated, with no adverse effects. There were no differences in weight loss at 12 weeks (-4.19 ± 0.5 kg for HP group and -3.72 ± 0.7 kg for SP group, p > 0.1). Subjects in the HP group lost significantly more fat weight than the SP group (HP = -1.65 ± 0.63 kg; SP = -0.64 ± 0.79 kg, P = 0.05) as estimated by BIA. There were no significant differences in lipids nor fasting blood glucose between groups, but within the HP group a significant decrease in cholesterol and LDL cholesterol was noted at 12 weeks. This was not seen in the SP group.Higher protein MR within a higher protein diet resulted in similar overall weight loss as the standard protein MR plan over 12 weeks. However, there was significantly more fat loss in the HP group but no significant difference in lean body mass. In this trial, subject compliance with both the standard and protein-enriched MR strategy for weight loss may have obscured any effect of increased protein on weight loss demonstrated in prior weight loss studies using whole food diets.Meal replacement shakes represent an important strategy in combating the worldwide epidemic of obesity due to their simplicity and convenience [1]. Meal replacement shakes have been studied extensively for both medical and public health efforts to

Abstract: To analyze the effect of field input on grain yield and economic benefit of farmlands, we used wheat-corn double crop-ping fields in northern Taihang Mountain Plain region of central Hebei to analyze the degree of response to input from farmland quality on basis of factor combination, hypothesis testing, regression analysis and agricultural land grade. The results suggest that grain yield can be improved by scientifically and reasonably increasing field input or using a combination of factors at low input. High yield on farmlands with poor natural conditions can be achieved through scientific and reasonable input. The optimal value of field input is within the interval between the maximum input-output benefit and maximum grain yield. Reasonably adjusted input based on differences in the influence of natural factors on grain yield and different factor combinations can increase yield significantly.

Abstract: In order to investigate the genetic diversity and estimate the genetic abundance of natural populations of Pleurotus eryngii var. tuoliensis, mating type factors in 84 protoplast monokaryons derived from 51 isolations collected from Xinjiang were analyzed. There were 54 different A factors and 59 different B factors in the 84 monokaryons. Chi-square test indicated that A and B factors were distributed with equal probability. Therefore there would be 79 different A factors and 100 distinct B factors in natural populations of P. eryngii var. tuoliensis in Xinjiang, China, and the putative mating type factors from monokaryon are 7,900, and for dikaryon, there would be 31,201,050 in nature. In conclusion, genetic diversity of P. eryngii var. tuoliensis is very high in Xinjiang, and Xinjiang is a valuable wild P. eryngii var. tuoliensis germplasm resource pool.

Abstract: Background The impact of interventions on the progressive course of COPD is currently assessed by the slope of the annual decline in FEV1 determined from serial measurements of the post-, in preference to the pre-, bronchodilator FEV1. We therefore compared the yearly slope and the variability of the slope of the pre- versus the post-bronchodilator FEV1 in men and women with mild to moderate COPD who participated in the 5-year Lung Health Study (LHS). Methods Data were analyzed from 4484 of the 5887 LHS participants who had measurements of pre- and post-bronchodilator FEV1 at baseline (screening visit 2) and all five annual visits. The annual rate of decline in FEV1 (±SE) measured pre- and post-bronchodilator from the first to the fifth annual visit was estimated separately using a random coefficient model adjusted for relevant covariates. Analyses were performed separately within each of the three randomized intervention groups. In addition, individual rates of decline in pre- and post-bronchodilator FEV1 were also determined for each participant. Furthermore, sample sizes were estimated for determining the significance of differences in slopes of decline between different interventions using pre- versus post-bronchodilator measurements. Results Within each intervention group, mean adjusted and unadjusted slope estimates were slightly higher for the pre- than the post-bronchodilator FEV1 (range of differences 2.6-5.2 ml/yr) and the standard errors around these estimates were only minimally higher for the pre- versus the post-bronchodilator FEV1 (range 0.05-0.11 ml/yr). Conversely, the standard deviations of the mean FEV1 determined at each annual visit were consistently slightly higher (range of differences 0.011 to 0.035 L) for the post- compared to the pre-bronchodilator FEV1. Within each group, the proportion of individual participants with a statistically significant slope was similar (varying by only 1.4 to 2.7%) comparing the estimates from the pre- versus the post-bronchodilator FEV1. However, sample size estimates were slightly higher when the pre- compared to the post-bronchodilator value was used to determine the significance of specified differences in slopes between interventions. Conclusion Serial measurements of the pre-bronchodilator FEV1 are generally sufficient for comparing the impact of different interventions on the annual rate of change in FEV1.

Selective Hybrid Encryption Algorithms for Secure Transmission of Electrical Energy Data
Li Jing,He Yanxiang
Asian Journal of Information Technology , 2012,
Abstract: The encryption algorithms previously proposed usually encrypt every data of electrical energy in order to maintain security and safety. However, the quantity of electrical energy data to be transmitted is very large and a majority of them are encrypted, so the encryption algorithms previously proposed increase the burden of communications and reduce the transmission efficiency. In this study, A Selective Hybrid Encryption Algorithm for secure transmission of electrical energy data is presented. The algorithm is based on SSL (Secure Sockets Layer). It adopts Encryption Algorithm AES (Advanced Encryption Standard) to encrypt important data of electrical energy and uses SHA-1(Secure Hash Algorithm) to get message digest. At the same time, The algorithm make also use of ECC Elliptic Curves Cryptography and AES to transmit data. With the method, the data of electrical energy encrypted can be transmitted highly active and safely.

Abstract: Objective To explore the efficacy and safety of different surgical approaches of cervical spondylotic myelopathy, and the predictive factors for the outcome of surgery. Methods Clinical data of 68 consecutive patients who underwent surgical treatment from 2003-08-01 to 2006-12-01 were collected. The quantization of the efficacy of operation was made by applying Japanese Orthopedic Association (JOA) scoring system, based on which the recovery rate and satisfaction rate were calculated. In the patients who underwent anterior approach, we compared the recovery rate among the subgroups of different duration of symptoms, age at surgery and the severity of diseases. Any surgery-related complications were also noted. Results 73.5% (50/68) patients underwent anterior approach, with an average recovery rate of (68.21 ± 10.06)% and the satisfaction rate of 88.00%; 20.6% patients (14/68) underwent posterior approach, with an average recovery rate of (64.03 ± 7.07)% and the satisfaction rate of 100%. The recovery rate had no significant difference in the two approaches. Only 4 patients (5.9%) underwent anterior and posterior combined approach, and the recovery rate and the satisfaction rate were 65.10% and 100%, respectively. In the group of patients who accepted anterior approach, no significant differences were found in the recovery rates of different age subgroups and different duration of symptom subgroups; the significant differences recovery rates between the moderate and severe subgroups were identified. Minor complications, such as asymptomatic screw misplacement, transient dysphagia/odynophagia, pain related to the donor site and axial syndrome, were observed in a few patients. Conclusion The JOA score can be improved by applying the appropriate approaches and the high recovery and satisfaction rates can be achieved at the same time. The efficacies of anterior and posterior approaches were similar. The complications of surgery were minor. In the patients who underwent anterior approach, the severity of diseases was a predictive factor for the outcome of surgery.
