The human leukocyte antigen (HLA) genes exhibit the highest degree of polymorphism in the human genome. This high degree of variation at classical HLA class I and class II loci has been maintained by balancing selection for a long evolutionary time. However, little is known about recent positive selection acting on specific HLA alleles in a local population. To detect the signature of recent po...

Background & aims: Malnutrition is common in geriatric patients and associated with poor outcome. If recognised, effective treatment is possible. In recent years, low nutritional awareness among health care professionals (HCPs) has been deplored with respect to the general hospital population. The aim of the present cross-sectional study was to assess to which extent malnutrition and nutrition-...

Background: Undernutrition/nutritional risk were evaluated longitudinally in 531 hospitalized elderly by four validated methods to appraise the most feasible for routine use. Design: Within 48hrs of admission&24hrs before discharge: the following data were collected: clinical data, nutritional status (BMI, %weight loss) & risk (MNA, MUST), energy requirements (Owen et al), diet. Results: Signif...

To optimize a suitable fertilization method needed for high nitrogen utilization and growth of mung bean in the black soil Northeast China, field experiment was carried out with 10 treatments based on isotope-tracing technology. The fertilizer utilization, residual, loss dry-matter transportation, leaf area, photosynthetic potential, wet-basis moisture content were discussed. results showed tha...

Soil organic matter (SOM) is essential for sustaining food production and maintaining ecosystem services and is a vital resource base for storing C and N. The impact of long-term use of synthetic fertilizer N on SOM, however, has been questioned recently. Here we tested the hypothesis that long-term application of N results in a decrease in SOM. We used data from 135 studies of 114 long-term ex...
