The paper examines the application of uncertainty theory to portfolio decision making, specifically focusing on constructing portfolio models based on uncertain preference relations. Firstly, we establish the theoretical foundation by introducing the theory of uncertainty, which includes uncertain m...

In the current study, a new polysaccharide named Bletilla striata polysaccharide (BSP) with an average molecular weight (Mw) of 85.4 kDa was obtained from B. striata. The inhibitory effects of BSP on α-amylase and α-glucosidase, as well as its prebiotic properties, were determined. The results showe...

The overexpression of soluble human leukocyte antigen-G is associated with malignant tumours. The purpose of our study was to detect soluble human leukocyte antigen-G concentrations in ascites and to evaluate the value of ascitic soluble human leukocyte antigen-G for the diagnosis of malignant ascit...

Arbuscular mycorrhizal fungi (AMF) symbiosis has great potential in improving grapevine performance and reducing external input dependency in viticulture. However, the precise, strain-specific impacts of different AMF species on ‘Summer Black’ grapevine cuttings across multiple physiological and mor...

Chitosan was effective in inhibiting radial growth and sporogensis of F. oxysporum. f. sp. ylcopersici in vitro. The inhibiting activity of chitosan was increased when its concentration increased. Light microscope observations showed that chitosan at concentration greater than 0.1 mg/mL induced morp...

Resistance to early blight of the tomato plants was induced by chitosan (1 mg/mL) at the fourth-leaf stage of seedlings. Chitosan treatment of tomato leaves before inoculation reduced the rates of diseased leaf and disease index. The relative efficiencies of resistance in cultivars were Hezuo908(hig...

Either arbuscular mycorrhizal fungi (AMF) or polyamines (PAs) may change root system architecture (RSA) of plants, whereas the interaction of AMF and PAs on RSA remains unclear. In the present study, we studied the interaction between AMF (Paraglomus occultum) and exogenous PAs, including putrescine...

Excessive nitrogen (N) fertilization in intensive agricultural areas such as the plain region of South China has resulted in low nitrogen use efficiency and serious environmental problems. To determine the optimum N application rate, grain yield, apparent nitrogen recovery efficiency (ANRE), apparen...

Three endophytes isolated from root nodules of Myrica rubra var. biji were identified as Frankia sp. and designated as Mpc11, Mpc12 and Mpa11 based on results of microscopic examination, inoculation, nitrogenase activitity measurement and Gram-staining. Characteristics of behavior of the three isola...

Heavy metal contamination has been regarded as an environmental variable that affects the efficiency of pest biological control, but the parasitic fitness of parasitoids under heavy metal stress is poorly understood. Herein, the effect of Cd exposure through the host pupa of Hyphantria cunea on the...

Adenocarcinoma and squamous cell carcinoma (SCC) of the same lobe of the lung is relatively rare. A 57-year-old man was admitted to Weifang People’s Hospital (Weifang, China) with blood streaks in sputum and had masses in the lung. Based on clinical, imaging, and pathological findings, the patient w...

Climate change is recognized to increase the frequency and severity of extreme temperature events. At flowering and grain filling stages, risk of high temperature stress (HTS) on rice might increase, and lead to declining grain yields. A regulated cabinet experiment was carried out to investigate ef...
