MiRNA-203a-5p alleviates the malignant progression of Wilms' tumor via targeting JAG1.

Objective: To uncover the potential influence of microRNA-203a-5p (miRNA-203a-5p) on the malignant progression of Wilms' tumor (WT).

Patients And Methods: MiRNA-203a-5p levels in 49 paired WT and paracancerous tissues were determined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Prognostic value of miRNA-203a-5p in WT was assessed by the Kaplan-Meier method.

Uncommon malignant renal tumors and atypical presentation of common ones: a guide for radiologists.

Objective: While the typical imaging features of the more common RCC subtypes have previously been described, they can at times have unusual, but distinguishing features. Rarer renal tumors span a broad range of imaging features, but they may also have characteristic presentations. We review the key imaging features of atypical presentations of malignant renal tumors and uncommon malignant renal tumors.

[Research progress of cover crop in Chinese orchard].

Grass growing in orchard is implemented in most fruit cultivation advanced countries, but only China carries out grass weeding. To effectively resolve the puzzle on harmful or beneficial effect on fruit production imparted by grass growing, and promote grass growing management in orchard in China, more and more domestic research was reported in recent years. Combined the results of our research and domestic related research, we reviewed the latest research progress about the effect of growing grass on soil, microclimate, fruit tree diseases and insect pests, tree growth and fruit quali- ty, etc.

[Radical surgery for Budd-Chiari syndrome through exposure of the whole hepatic segment of inferior vena cava].

Objective: To summarize the preliminary experience of a new type of radical treatment of Budd-Chiari syndrome under genuine direct vision.

Methods: We retrospectively analyzed the clinical data of 60 patients who were treated with radical exposing the whole inferior vena cava of hepatic segment in our hospital from September 2001 to October 2006.

Results: All lesions were completely resected under direct vision.

Formation of the ferritin iron mineral occurs in plastids.

Ferritin in plants is a nuclear-encoded, multisubunit protein found in plastids; an N-terminal transit peptide targets the protein to the plastid, but the site for formation of the ferritin Fe mineral is unknown. In biology, ferritin is required to concentrate Fe to levels needed by cells (approximately 10(-7) M), far above the solubility of the free ion (10(-18) M); the protein directs the reversible phase transition of the hydrated metal ion in solution to hydrated Fe-oxo mineral. Low phosphate characterizes the solid-phase Fe mineral in the center of ferritin of the cytosolic animal ferritin, but high phosphate is the hallmark of Fe mineral in prokaryotic ferritin and plant (pea [Pisum sativum L.
