Effect of fertilizers on Cd uptake of Amaranthus hypochondriacus, a high biomass, fast growing and easily cultivated potential Cd hyperaccumulator.

In a greenhouse pot experiment, we assessed the phytoextraction potential for Cd of three amaranth cultivars (Amaranthus hypochondriacus L. Cvs. K112, R104, and K472) and the effect of application of N, NP, and NPK fertilizer on Cd uptake of the three cultivars from soil contaminated with 5 mg kg(-1) Cd.

[Risk factors of cognitive impairment after off-pump coronary artery bypass grafting].

Objective: To analyze the risk factors of cognitive impairment after off-pump coronary artery bypass grafting (OPCABG).

Methods: A total of 102 patients [male: 82, age: (65.7 ± 7.

Biodegradation of bensulfuron-methyl and its effect on bacterial community in paddy soils.

Bensulfuron-methyl (BSM) is a new kind of sulfonylurea herbicide widely used to control broad-leaf weeds in rice paddies. The aim of this work was to study BSM biodegradation in paddy soils with BSM-degrading bacteria Bacillus megaterium L1 and Brevibacterium sp. BH and its effect on the structures of soil bacterial community.

The efficacy and safety of melatonin in concurrent chemotherapy or radiotherapy for solid tumors: a meta-analysis of randomized controlled trials.

Background: Recently, melatonin has been associated with cancer both in vitro and in vivo. However, the value of melatonin in the treatment of cancer remains disputable. Hence, we performed a systematic review of randomized controlled trials (RCTs) of melatonin in solid tumor cancer patients and observed its effect on tumor remission, 1-year survival, and side effects due to radiochemotherapy.

[Effects of open heart surgery under normothermic and hypothermic cardiopulmonary bypass on cytokines and complements].

Objective: To explore the detrimental influence of normothermic and hypothermic cardiopulmonary bypass during open heart surgery on cytokines and complements.

Method: Forty patients with congenital or rheumatic heart disease were randomized into 2 groups to receive normothermic cardiopulmonary bypass (CPB, study group, n=20) or hypothermic CPB (control group, n=20). Venous blood samples were respectively collected at scheduled time points preoperatively, at the end of CPB, and 1,4,7,14 d postoperatively to examine the level of interleukin (IL)-2, tumor necrosis factor (TNF)-alpha, C3, and C4.

[Effects of hypothermia on cerebral oxygen metabolism in patients with mitral valve replacement].

Objective: To observe the effects of mild to moderate hypothermia on cerebral oxygen metabolism in patients with mitral valve replacement.

Methods: Twenty patients undergoing mitral valve replacement were randomly divided in mild (30 ) and moderate (26 degrees Celsius) hypothermia groups. Under alpha stat, the oxygen content and the concentration of lactic acid in the radial artery and jugular venous bulb were monitored in patients undergoing mitral valve replacement at mild and moderate hypothermia respectively.
