Arsenic-hyperaccumulator Pteris vittata exhibits remarkable absorption ability for chromium (Cr) while beneficial element selenium (Se) helps to reduce Cr-induced stress in plants. However, the effects of Se on the Cr uptake and the associated mechanisms in P. vittata are unclear, which were investigated in this study.

In this study, P. vittata was exposed to 50 μM arsenate (AsV) under hydroponics plus 25 or 50 μM foliar selenate.

- The study examines how copper (Cu) affects arsenic (As) accumulation in the As-hyperaccumulator plant Pteris vittata under hydroponic conditions.
- Results show that when exposed to both 50 µM As and Cu, P. vittata exhibited a 1.4-fold increase in As concentration and a 1.2-fold increase in biomass compared to As alone.
- The enhanced As uptake is linked to the upregulation of specific genes related to arsenic transport, translocation, and sequestration in the plant, suggesting potential for using P. vittata in cleaning up soils contaminated with both As and Cu.
[Preliminary report of laryngeal preservation in the surgical salvage of recurrent laryngeal cancer].

July 2012
Objective: To explore the plausibility of laryngeal preservation in salvage surgery of recurrent laryngeal carcinoma.
Methods: Comprehensive clinical and radiological assessments on a specific group of patients with recurrent laryngeal cancer and their relapsed tumors were carried out to determine the methods and indications of salvage surgery for preservation of laryngeal functions. Salvage surgery with preservation of larynx was performed in a selective of 36 laryngeal cancer patients with relapsed tumors in their larynges after radiotherapy or partial laryngectomies.
[Long-term results of one stage tracheoesophageal end-side anastomosis voice restoration after total laryngectomy].

September 2002
Objective: The purpose of this study is to discuss long-term results of one different kind of voice restoration after total laryngectomy with 10 years experience.
Method: One stage tracheoesophageal end-side anastomosis after total laryngectomy was performed in 36 patients from 1991-1996. The key technique of this operation is to make a tongue-ship flap(1.
