Effect of nitrogen levels on grain yield and quality in improving mid-season japonica rice varieties.

Background: Nitrogen application is recognized as a principal factor influencing rice quality. However, there remains a paucity of research on the effects of different N levels on quality, particularly within the context of the improvement of rice varieties.

Results: This study examined 14 mid-season japonica rice varieties cultivated in Jiangsu province over the past 80 years under five N application levels (0, 90, 180, 270, and 360 kg N ha).

NRT1.1B mediates rice plant growth and soil microbial diversity under different nitrogen conditions.

Interactions between microorganisms and plants can stimulate plant growth and promote nitrogen cycling. Nitrogen fertilizers are routinely used in agriculture to improve crop growth and yield; however, poor use efficiency impairs the optimal utilization of such fertilizers. Differences in the microbial diversity and plant growth of rice soil under different nitrogen application conditions and the expression of nitrogen-use efficiency-related genes have not been previously investigated.

Genetic Profiling of Breast Cancer with and Without Preexisting Metabolic Disease.

Breast cancer is the most commonly diagnosed cancer and the leading cause of cancer death among women. Various mechanisms are involved in the initiation and progression of breast cancer. Metabolic dysregulation has been associated with increasing breast cancer incidence and mortality.

Expression and clinical significance of autophagic protein LC3B and EMT markers in gastric cancer.

Background And Aim: Gastric cancer (GC) is a fatal malignancy with high rate of recurrence and metastasis. Here, we investigated the correlations between the expression of autophagic protein LC3B and 2 epithelial-mesenchymal transition-related proteins (E-cadherin and Vimentin) and the clinicopathological factors and prognosis of patients with GC.

Materials And Methods: The expression of LC3B, E-cadherin, and Vimentin in GC samples (110 cases) and paracarcinoma tissues (40 cases) was analyzed using the Oncomine databases and further detected by immunohistochemistry.
