Weight Loss Is Still an Essential Intervention in Obesity and its Complications: A Review
Jianzhong Xiao,Wenying Yang
Journal of Obesity , 2012, DOI: 10.1155/2012/369097
Abstract: The prevalence of obesity is more than 20% in many developed countries and it increases in developing countries. Obesity is associated with metabolic disorders, cardiovascular diseases, pulmonary diseases, digestive diseases, and cancers. Although other specific treatments for these complications exist, weight loss is still an essential intervention in obesity and its complications. Therapeutic life change, behavior modification, pharmacotherapy, and surgery are major approaches to weight loss. In addition, medicine used in diabetes such as Glucagon-like peptide-1 analogues may be a new type of medicine for obesity, at least for those obese patients with diabetes.
Weight Loss Is Still an Essential Intervention in Obesity and its Complications: A Review

Abstract: The prevalence of obesity is more than 20% in many developed countries and it increases in developing countries. Obesity is associated with metabolic disorders, cardiovascular diseases, pulmonary diseases, digestive diseases, and cancers. Although other specific treatments for these complications exist, weight loss is still an essential intervention in obesity and its complications. Therapeutic life change, behavior modification, pharmacotherapy, and surgery are major approaches to weight loss. In addition, medicine used in diabetes such as Glucagon-like peptide-1 analogues may be a new type of medicine for obesity, at least for those obese patients with diabetes. 1. Introduction In 2005 the International Association for the Study of Obesity reported that the prevalence of obesity, defined by BMI ≥ 30?kg/m2 is more than 20% in many European countries [1]. Future obesity for adults in the United States was projected on the basis of National Health and Nutrition Examination Study. By 2030, 86.3% American adults will be overweight or obese; 51.1% of them will be obese. Total health-care costs attributable to obesity/overweight would double every decade to 2030, accounting for 16–18% of total US health-care costs [2]. In China, a fast developing country, the prevalence of overweight and obesity also increased in the last two decades. The prevalence of overweight and obesity in 2008 in Chinese population aged 20 years or older reached 24.9%, 4.9% in women and 30.8% and 6.0% in men, respectively [3]. Timely and effective development and implementation of corrective approaches are needed to avoid the catastrophic health and social consequences. 2. Obesity and Chronic Diseases Obesity is associated with a cluster of metabolic risk factors for coronary heart disease (CHD), known as metabolic syndrome. Abdominal obesity is an essential component of this syndrome, other components include impaired glucose regulation and type 2 diabetes mellitus; hypertriglyceridemia and/or low serum HDL-cholesterol levels; hypertension. In addition, increased serum levels of C-reactive protein; apolipoprotein B; small, dense LDL particles are also associated with abdominal obesity [4, 5]. The epidemic of obesity is accompanied by the increase of these metabolic risk factors. The drastic increase in the prevalence of obesity has played an important role in the spread of diabetes not only in the United States [6, 7], but also in China. The prevalence of diabetes increases from 12.8% in those with a BMI of 25.0 to 29.9?kg/m2 to 18.5% in those with a BMI greater than 30?kg/m2. This
A Unified Framework Integrating Parent-of-Origin Effects for Association Study

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0072208
Abstract: Genetic imprinting is the most well-known cause for parent-of-origin effect (POE) whereby a gene is differentially expressed depending on the parental origin of the same alleles. Genetic imprinting is related to several human disorders, including diabetes, breast cancer, alcoholism, and obesity. This phenomenon has been shown to be important for normal embryonic development in mammals. Traditional association approaches ignore this important genetic phenomenon. In this study, we generalize the natural and orthogonal interactions (NOIA) framework to allow for estimation of both main allelic effects and POEs. We develop a statistical (Stat-POE) model that has the orthogonal estimates of parameters including the POEs. We conducted simulation studies for both quantitative and qualitative traits to evaluate the performance of the statistical and functional models with different levels of POEs. Our results showed that the newly proposed Stat-POE model, which ensures orthogonality of variance components if Hardy-Weinberg Equilibrium (HWE) or equal minor and major allele frequencies is satisfied, had greater power for detecting the main allelic additive effect than a Func-POE model, which codes according to allelic substitutions, for both quantitative and qualitative traits. The power for detecting the POE was the same for the Stat-POE and Func-POE models under HWE for quantitative traits.
Prediction of Landscape Pattern of Soft Sandstone Area (SSA) after Seabuckthorn Planting  [PDF]

American Journal of Plant Sciences (AJPS) , 2012, DOI: 10.4236/ajps.2012.31020
Abstract: As a pioneer plant in the gully slopes in the Soft Sandstone Area (SSA) for eco-economical consideration, ten years (1999-2008) planting of seabuckthorn has made 1642.83 km2, or 9.84%, of the total area of SSA change into seabuckthorn coverage. In SSA the landscape has been divided into 9 types, such as seabuckthorn, sand, water, settlement, bush, open vegetation, forest, grassland and unused land. Seabuckthorn type is separated from the bush type for estimating the role of seabuckthron planting. By means of the Markov model, the developing trends of every landscape types can be determined to support the seabuckthorn project which influences the landscape pattern deeply in SSA. The prediction shows that the optimism ratio of seabuckthorn in the future should be 10.21%, the open vegetation 32.25%, and the forest percentage under 10%, which is a very wise tactics to avoid the serious death of various vegetations in SSA to match the local arid eco-environment.

American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.412286
Abstract:

China Seabuckthorn Ecological Project has been implemented for a decade (from 1999 to 2008) with an increasing seabuckthorn area of 1642.83 km2 in the Sandstone Areas of Shanxi, Shaanxi and Inner Mongoliathe most serious soil erosion area in China. The vast artificial seabuckthorn forest’s value in environmental resource is assessed via 7 indicators on first-level, 15 indicators on secondary level and 35 indicators on third level in this research. As of 2008, the seabuckthorn environmental resource value is 10.017 billion RMB Yuan, which equals to 37.1 times of the project’s total investment of 0.27 billion RMB Yuan. It is proposed in this research that the external economical values such as soil and water conservation, windbreak and sand-fixation can be realized through relative national policies and taxes. Carbon-fixation and oxygen-producing value can be achieved through the international carbon trade.

PIER M , 2011, DOI: 10.2528/PIERM11092606
Abstract: The existence of reverse radiation noise in the millimeter-wave (MMW) radiometric imaging system with a superheterodyne receiver seriously affects the imaging experiments carried out at short range, thus leading to the degradation of MMW radiometric images and difficulty in recognizing targets. Based on the generation mechanism of reverse radiation noise, the specific influence on imaging for relative radiometry is investigated in this paper, and some methods of eliminating or reducing this noise are proposed. Then, two series of comparative imaging experiments are conducted with a 3 mm band radiometric imaging system. Both theoretical analysis and experimental results are presented to validate the actual existence of interference-like stripes imposed by the reverse radiation noise. Moreover, it is proved that adopting an isolator in the MMW receiving front-end can effectively reduce the reverse radiation noise and significantly improve the imaging performance.
Efficient Pr-Skyline Query Processing and Optimization in Wireless Sensor Networks  [PDF]
Jianzhong Li, Shuguang Xiong
Wireless Sensor Network (WSN) , 2010, DOI: 10.4236/wsn.2010.211101
Abstract: As one of the commonly used queries in modern databases, skyline query has received extensive attention from database research community. The uncertainty of the data in wireless sensor networks makes the corresponding skyline uncertain and not unique. This paper investigates the Pr-Skyline problem, i.e., how to compute the skyline with the highest existence probability in a computational and energy-efficient way. We formulate the problem and prove that it is NP-Complete and cannot be approximated in a given expression. However, the proposed algorithm SKY-SEARCH with pruning techniques can guarantee the computational efficiency given relatively large input size, while the filter-based distributed optimization strategy significantly reduces the transmission cost and the required storage space of the sensor nodes. Extensive experiments verify the efficiency and scalability of SKY-SEARCH and the distributed optimizing strategy.
