Characteristics of soil nitrogen and phosphorus fractions and microbial traits with increasing stand age in two-layered + plantations.

Soil nitrogen and phosphorus are two key elements limiting tree growth in subtropical areas. Understanding the regulation of soil microorganisms on nitrogen and phosphorus nutrition is beneficial to reveal maintenance mechanism of soil fertility in plantations. We analyzed the characteristics of soil nitrogen and phosphorus fractions, soil microbial community composition and function, and their relationship across three stands of two-layered + with different ages (4, 7 and 11 a) and the pure plantation.

Solitary primary pulmonary synovial sarcoma: A case report.

Background: Synovial sarcoma (SS) is an uncommon and highly malignant soft tissue sarcoma in the clinic, with primary pulmonary SS (PPSS) being extremely rare. Here, we describe the clinical characteristics, diagnosis, and treatment of a solitary PPSS case confirmed surgical resection and fluorescence in situ hybridization (FISH).

Case Summary: A 33-year-old man was admitted because of intermittent coughing and hemoptysis for one month, with lung shadows observed for two years.

Enhancement of cellular uptake and antitumor efficiencies of micelles with phosphorylcholine.

Internalization of drug delivery micelles into cancer cells is a crucial step for antitumor therapeutics. Novel amphiphilic star-shaped copolymers with zwitterionic phosphorylcholine (PC) block, 6-arm star poly(ε-caprolactone)-b-poly(2-methacryloyloxyethyl phosphorylcholine) (6sPCL-b-PMPC), have been developed for encapsulation of poorly water-soluble drugs and enhancement of their cellular uptake. The star-shaped copolymers were synthesized by a combination of ring-opening polymerization (ROP) and atom transfer radical polymerization (ATRP).
