Flood inundation evolution of barrier lake and evaluation of regional ecological spatiotemporal response-a case study of Sichuan-Tibet region.

The Himalayan volcanic earthquake zone has significantly impacted China's Sichuan-Tibet region. Many barriers have formed as a result of the earthquake and secondary disasters, such as landslides, which have blocked the river. The breach of the barrier lake seriously threatens the lives and property safety of downstream personnel.

Comparison anterior minimally invasive oblique retroperitoneal approach and posterior transpedicular approach for debridement fusion in patients with lumbar vertebral osteomyelitis: A randomized controlled trial protocol.

Background: Pyogenic osteomyelitis of the spine usually occurs in patients over 55 years old with acute osteomyelitis. Surgical treatment and fixation can relieve pain, enhance spinal balance and nerve function, so that patients can walk as soon as possible. Different outcomes of surgical methods include anterior minimally invasive oblique retroperitoneal approach (ORA) and posterior transpedicular approach (PTA).

Chemiluminescence method for the determination of piroxicam by the enhancement of the tris-(4,7-diphenyl-1,10-phenanthrolinedisulphonic acid) ruthenium(II) (RuBPS)-cerium(IV) system and its application.

A simple, rapid chemiluminescence (CL) method was described for the determination of piroxicam, a commonly used analgesic agent drug. A strong CL signal was detected when cerium(IV) sulphate was injected into tris-(4,7-diphenyl-1,10-phenanthrolinedisulphonic acid) ruthenium(II) (RuBPS)-piroxicam solution. The CL signal was proportional to the concentration of piroxicam in the range 2.

The p-benzoquinone DNA adducts derived from benzene are highly mutagenic.

Benzene is a human leukemia carcinogen, resulting from its cellular metabolism. A major benzene metabolite is p-benzoquinone (pBQ), which can damage DNA by forming the exocyclic base adducts pBQ-dC, pBQ-dA, and pBQ-dG in vitro. To gain insights into the role of pBQ in benzene genotoxicity, we examined in vitro translesion synthesis and in vivo mutagenesis of these pBQ adducts.
