The salmon effluent failed the acute lethality test using rainbow trout while the flatfish effluent showed acute toxicity in the Microtox (TM) test with a 50% inhibiting concentration (IC(50)) of
38.84%. Subsequent treatment by DAF of the flatfish and salmon effluents increased IC(50) values by 20% and 26% respectively. The findings of this study DMH1 clinical trial indicate that all of the processing effluents sampled showed characteristics that could potentially degrade effluent receiving waters and acute toxicity was demonstrated in the two raw finfish effluents. Application of DAF treatment was successful in significantly increasing Microtox (TM) IC(50) values, thereby reducing acute toxicity, but failed to entirely remove acute toxicity.

“We examined lumbar transpedicular instrumented posterolateral fusion patients operated on between 1992 and 1997 presenting: degenerative spondylolisthesis with spinal stenosis; adult isthmic spondylolisthesis; failed back syndrome after one to five discectomies; and failed back syndrome after one to three laminectomy operations
(Groups 1-4, respectively).
They were examined by an independent orthopedic surgeon, completed the Oswestry Disability Index (ODI) and visual analog scale (VAS) questionnaires and their outcome was evaluated.
The overall patient satisfaction at follow-up (mean 11.7 years) was 82.1 %. The reoperation rate was 15.1 % (7.5 % due to adjacent segment disease).
Group 1 showed the greatest improvements in ODI and VAS values, Group 2 the lowest and Group 3 the highest preoperative values, and Staurosporine research buy Group 4 the second highest improvements. Patient satisfaction see more scores were 90.3, 69.7, 63.6 and 80.0 %, respectively, and unplanned reoperation rates were 6.5, 9.1, 31.8 and 20.0 %. Thus, long-term outcomes of lumbar instrumented posterolateral fusion (rarely previously studied) were satisfactory for > 80 % of patients, but varied among groups.”
“Bentazon
and molinate are selective herbicides recommended for integrated weed management in rice. Their toxicity on growth and some biochemical and physiological parameters of Nostoc muscorum, an abundant cyanobacterium in Portuguese rice fields, was evaluated under laboratory conditions during time- and concentration-dependent exposure for 72 h. Results showed that toxic concentrations (0.75-2 mM) of both herbicides have pleiotropic effects on the cyanobacterium. Molinate was more toxic than bentazon to growth, respiration, chlorophyll-a, carotenoids, and phycobiliproteins contents. Protein content was increased by both herbicides although the effect was particularly evident with higher concentrations of molinate (1.5-2 mM). The herbicides had contrasting effects on carbohydrates content: molinate increased this organic fraction whereas bentazon decreased it. Photosynthesis and respiration were inhibited by both herbicides. (C) 2009 Wiley Periodicals, Inc.
