Association between quantitative spectral CT parameters, Ki-67 expression, and invasiveness in lung adenocarcinoma manifesting as ground-glass nodules.

Background: Few studies about lung ground-glass nodules (GGNs) have been done using non-enhancement spectral computed tomography (CT) imaging.

Purpose: To examine the association between spectral CT parameters, Ki-67 expression, and invasiveness in lung adenocarcinoma manifesting as GGNs.

Material And Methods: Spectral CT parameters were analyzed in 106 patients with lung GGNs.

The E3 ligase UBR5 regulates gastric cancer cell growth by destabilizing the tumor suppressor GKN1.

Gastric cancer is the most common digestive malignant tumor worldwide and the underlying mechanisms are not fully understood. The E3 ligase UBR5 (also known as EDD1) is essentially involved in diverse types of cancer. Here we aimed to study the functions of UBR5 in human gastric cancer.

EDD1 predicts prognosis and regulates gastric cancer growth in vitro and in vivo via miR-22.

Gastric cancer is the most common digestive malignant tumor worldwild. EDD1 was reported to be frequently amplified in several tumors and played an important role in the tumorigenesis process. However, the biological role and potential mechanism of EDD1 in gastric cancer remains poorly understood.

[Physiological responses of different cucumber cultivars seedlings to iso-osmotic Mg (NO3) 2 and NaCl stress].

In this study, the effects of iso-osmotic solution of Mg (NO3) 2 and NaCl on seedling growth, leaf lipid peroxidation, antioxidant enzyme activities, and osmotic adjustment substance accumulation were investigated using three cucumber cultivars with different ecotypes. Then salt tolerance was evaluated by membership function method. The results revealed that under the stress of 60 and 80 mmol x L(-1) Mg(NO3) 2 solution and its isotonic 90 and 120 mmol x L(-1) NaCl solution, the seedling traits such as height, stem diameter, leaf area, fresh and dry mass of aerial part and underground parts, and antioxidant enzymes activity were obviously decreased with the increasing concentration of Mg( NO3)2 and its isotonic NaCl in the three cucumber cultivars.

[Significance of microRNA-146b-5p in diffuse large B-cell lymphoma and its relationship with risk assessment].

Objective: To study the expression of miR-146b-5p in diffuse large B cell lymphoma (DLBCL), and its relationship with risk assessment.

Methods: 62 cases of nodal DLBCL with follow-up data were collected from Shanxi Cancer Hospital, and were studied by using immunohistochemical EnVision method for CD3, CD10, CD20, Bcl-6 and MUM1. The DLBCLs were classified into germinal center B cell-like (GCB) and non-germinal center B cell-like (non-GCB) subtypes according to Hans'algorithm.

[Distribution and accumulation characteristics of nutrients in solar greenhouse soil in Ji'nan, Shandong Province of East China].

Taking the solar greenhouses with different cultivating years and vegetables in Ji'nan as test objects, this paper studied the amounts and frequency distribution of soil nutrients and the relationships between cultivating years and soil nutrients accumulation characteristics, and analyzed the factors causing soil salinization and acidification by fitting soil nutrients contents with cultivating years and vegetables. In the greenhouses, the contents of soil alkali-hydrolysable nitrogen, available phosphorus, available potassium, organic matter, and electrical conductivity were significantly higher than those in the open field, with an increment of 135.3%, 475.
