[Method] The present study consisted of five treat- ments： 1 CK （no fertilizer or manure）, （2） NP （nitrogen and phosphorus fertilizer applied）, 31 NK （nitrogen and potassium fertilizer applied）, 4 PK （phosphorus and potassium fertilizer applied） and ：5 NPK （nitrogen, phosphorus and potassium fertil- izer applied）. [Result] Lacking of nitrogen or phosphorus led to a low yield; however, there was no significant difference in grain yields between the NP and NPK treat- ments which maintained a higher yield. Receiving no phosphorus, soil available phosphorus content declined to about 2.5 mg/kg. The concentration of soil ex- changeable potassium remained constant at a level of 60 mg/kg under the treat- ments without potassium fertilizer addition. Soil potassium spontaneous supply ca- pacity fluctuated around 100%.[Conclusion] In fluvo-aquic soil, nitrogen and phos- phorus were two key limiting factors to grain yields, biomass and yield component factors of wheat and maize, while potassium was not. However, potassium defi- ciency may occur in the future if there was still no potassium fertilizer applied.展开更多

[Method] Six hybrid rice vari- eties including prematurely aged types and non-prematurely aged ones were selected as experimental materials. Limiting water treatment （with soil water potential of about -25 kpa） and increasing nitrogen treatment （additional 10% of granular nitrogen fertiliz- er in addition to limiting water treatment） were applied after heading to analyse the rates of aging and physiological responses of anti-aging in different hybrid rice vari- eties under water deficit and increased nitrogen conditions taking regular water and fertilizer as control. [Result] The results showed that water deficit accelerated the leaf senescence, and prematurely aged types-＇Zhongyou838＇, ＇Tianyou998＇ and ＇Long- ping601 ＇-were more markedly affected by water deficit, of which the rates of chloro- phyll degradation were 6%-8% higher compared to that in another three hybrids. In- creasing nitrogen treatment raised chlorophyll content and slowed down its degrada- tion. Water deficit caused the increase of abscisic acid （ABA） content to obviously varying degrees in leaves of six hybried rice varieties. Responses of ABA content in six hybried rice varieties to increased nitrogen fertilizer were not consistent. Except in ＇Zhongyou838＇, ABA content in the other five hybrids had varying degrees of in- crease. The responses of the activity of antioxidant enzymes in different hybried rice varieties were inconsistent. In response to increased nitrogen fertilizer in combination with water deficit, the activity of each antioxidant enzyme changed differently. Water deficit enhanced the accumulation of malondialdehyde （MDA） in leaves of each hybrid rice. The correlation analysis showed that chlorophyll content was extremely signifi- cantly positively correlated to the resistance of each antioxidant enzyme; SOD activity in leaves also positively related to ABA content. [Conclusion] The rate of leaf aging, physiological activity of anti-aging, and response to water deficit varied in different hy- bried rice varieties. The activity of antioxidant enzymes were not all induced to improve by ABA. SOD activity can be an indicator of resistance to stress. Increasing nitrogen ap- plication significantly postponed leave senescence in the late growth stage of rice.展开更多

The Student's t-test, x2 test and multivariate logistic regression analysis were utilized to evaluate the relationship between IHD and salient risk factors.RESULTS: The all-over prevalence of overweight was 41.4%, and that of fatty liver was 29.5% (mild, moderate and severe fatty liver being 14.5%, 11.3%, and 3.7%,respectively); while the prevalence of ischemic changes on ECG was 17.1% in this study. The abnormal rates for conventional IHD risk factors including hypertension,dyslipidemia, hyperglycemia and overweight increased in accordance with the severity of fatty liver. Overweight and severity of fatty liver were independently associated with increased risks for developing IHD. Overweight subjects had a 1.32-fold (95%CI: 1.01-1.73) increased IHD risk. Participants with mild, moderate, and severe fatty liver had a 1.88-fold (95%CI: 1.37-2.6), 2.37-fold (95%CI: 1.66-3.37) and 2.76-fold (95%CI: 1.62-4.72)increased risk for developing IHD. The prevalence of ischemic ECG for the fatty liver-affected subjects with or without overweight was 30.1% and 19.1%, while that of overweight subjects free from fatty liver was 14.4%.Compared to the subjects without fatty liver nor overweight,IHD risk for the three subgroups above was as follows:OR: 2.95 (95%CI:2.31-4.09), OR: 1.60 (95%CI: 1.07-2.39)and OR: 1.11 (95%CI: 0.78-1.56), respectively.CONCLUSION: The presence of fatty liver and its severity should be carefully considered as independent risk factors for IHD. Results of the study suggest the synergistic effect between fatty liver and overweight for developing IHD.Abdominal sonographic examination may provide valuable information for IHD risk assessment in addition to limited report about liver status, especially for overweight males.展开更多

The added N advanced growth stages as well as increased corn heights and CMRs at any given time.Fertilization effects on corn heights,growth stages and ear weights were statistically significant (P<0.05) despite substantial variability associated with landscape.Reductions in growth due to a temporary shortage of N within a growth stage might be partially offset by longer periods of growth within that stage to physiological maturity.Temporary shortages of N,therefore,may produce symptoms of N deficiency in situations where subsequent additions of N should not be expected to increase yields.Recognition of these two somewhat different effects (i.e.,increase growth rates and advance growth stages) on corn growth could help to define N deficiency more precisely and to improve the accuracy of diagnosing N status in production agriculture.展开更多

Certain foods with chemical additives disguised as food can cause muscle and joint pain associated with arthritis, gout, fibromyalgia, obesity, cancer and others. Avoiding these foods can reduced inflammation, thus prevent obesity, cancer, and another disease. The target of the study was to find a relation between food type, anthropometric parameters and obesity-related diseases for university students in CoUege-Al Leith-Umm al-Qura University, Saudi Arabia. The purpose is to identify populations （100 subjects women, aged： 17-30 year, using questionnaire） who are malnourished or at nutritional risk. Participants were divided into normal-weight and obese groups. The different methods are used to collect data including： 1. Anthropometric, 2. Dietary： Nutritional History （Current Intake）, 3. FFQ （Food frequency questionnaire）. There is a significant association between certain food type, anthropometric parameters, obesity as well as other diseases including （vitamin D deficiency, kidney problems, bone pain, general weakness, thyroid problems, infertility.展开更多

Despite the advances in treating CVDs, the prevalence of HF con- tinues to increase. It is believed that better results of prognosis are obtained from prevention rather than additional treatment for HF. Therefore, it is reasonable to prevent the development of CVDs or other complications to HF. Most types of HF are attributed to contractile dysfunction, cardiac hypertrophy or remodeling, and ischemic injuries. SIRT3 is a mitochondrial nicotinamide adenine dinucleotide （NAD＊）-dependent deacetylase whose substrates vary from met- abolic biogenesis-associated proteins to stress-responsive proteins. In recent years, a number of studies have high- lighted the cardio-protective role of SIRT3 and, as such, efforts have been made to induce over-expression or in- creased activity of this protein. In this review, we provide an overview of the roles of SIRT3 in cardiac hypertrophy induced by pressure overload or agonists and cardiomyocytes ischemic injuries. Moreover, we will introduce the application of SIRT3 agonists in the prevention of cardiac hypertrophy and ischemia reperfusion injury.展开更多

Free vascularized fibular grafting （FVFG） is considered to be a reliable reconstructive procedure. Stress fractures are a common complication following this surgery, and hypertrophy is the main physiological change of the grafted fibula. The exact mechanism of hypertrophy is not completely known. To the best of our knowledge, no studies have examined the possible relationship between stress fractures and hypertrophy. We herein report three cases of patients underwent FVFG. Two of them developed stress fractures and significant hypertrophy, while the remaining patient developed neither stress fractures nor significant hypertrophy. This phenomenon indicates that a relationship may exist between stress frac~ tures and hypertrophy of the grafted fibula, specifically, that the presence of a stress fracture may initiate the process of hypertrophy,展开更多
