Synthesis and Biological Evaluation of Novel Meroterpenoid Derivatives against Cisplatin-Induced Acute Kidney Injury.

Cisplatin is a widely used drug for the clinical treatment of tumors. However, nephrotoxicity limits its widespread use. A series of compounds including eight analogs () and 40 simplifiers () were synthesized based on the total synthesis of Psiguamer A and B, which were novel meroterpenoids with unusual skeletons from the leaves of .

Metabolomic and transcriptomic profiling of three types of litchi pericarps reveals that changes in the hormone balance constitute the molecular basis of the fruit cracking susceptibility of Litchi chinensis cv. Baitangying.

Many Litchi chinensis cv. Baitangying orchards are suffering from a serious fruit cracking problem, but few studies have improved our understanding of the mechanism or the molecular basis of cracking susceptibility in 'Baitangying'. We conducted metabolome and transcriptome analyses of three types of litchi pericarps.

Coarctation of the Aorta with Aortic Arch Hypoplasia: Midterm Outcomes of Aortic Arch Reconstruction with Autologous Pulmonary Artery Patch.

Background: Coarctation of the aorta (CoA) with aortic arch hypoplasia (AAH) is a relatively common congenital heart disease in clinical practice. Nonetheless, the corrective surgical technique for infants and children is a clinical problem that remains controversial. In this study, we sought to evaluate the surgical effects of aortic arch (AA) reconstruction with coarctation resection and aortoplasty with autologous pulmonary artery patch for infants and young children with CoA and AAH.

[Drug resistance and associated factors on HIV in Liangshan prefecture, Sichuan province].

Objective: To investigate the HIV drug resistance among HIV/AIDS patients who had received highly active antiretroviral treatment (HAATR) in Liangshan prefecture and related factors.

Methods: This investigation was conducted from August to October 2010. Data on epidemiology, treatment, CD4(+) T cell, viral load and drug resistance tests were collected.

[Determination of trace chrysene in environmental water by solid-phase microextraction coupled with high performance liquid chromatography].

A rapid method for the determination of trace chrysene in environmental water by solid-phase microextraction (SPME) coupled with high performmnce liquid chromatography (HPLC) was developed. The experimental conditions of SPME, such as extraction time, extraction temperature, effect of ion strength, desorption time, desorption solution, desorption mode and the analytical conditions of HPLC were optimized. The optimal conditions were room temperature, 1,100 r/min of stirring rate, 30 min of extraction time, 3 min of desorption time, and methanol as the desorption solution.
