Pig farm biogas slurry can effectively reduce the pH of saline-alkali soils.

Pig farm biogas slurry is being increasingly used as a potent organic fertilizer for sustainable agriculture under circular economy. However, the effect of biogas slurry on soil pH is currently controversial, and the underlying mechanisms especially in saline-alkali soils are not well understood. A saline-alkali soil (pH = 9.

The Role of Hippocampal Structural Synaptic Plasticity in Repetitive Transcranial Magnetic Stimulation to Improve Cognitive Function in Male SAMP8 Mice.

Background: Repetitive transcranial magnetic stimulation (rTMS) has been used to improve cognitive function, but the stimulation protocols are variable and the underlying mechanism is unclear. Therefore, we intend to examine whether 5Hz rTMS with 30% maximum output could improve cognitive functions in senescence-accelerated-prone mouse 8 (SAMP8) through changing synaptic plasticity.

Methods: SAMP8 and senescence-accelerated-prone mouse/resistant 1 (SAMR1) (7-month old male) were randomly divided into 3 groups: SMAP8 rTMS group (P8-rTMS), SMAP8 sham-rTMS group (P8-sham), and SAMR1 sham-rTMS group (R1-sham).

[Short fusion and long fusion for degenerative lumbar scoliosis with lumbar stenosis].

Objective: To explore the indications, surgical techniques and prognostic factors of short fusion versus long fusion for elder patients with degenerative lumbar scoliosis.

Methods: Thirty-eight patients undergoing different kinds of surgical procedures for lumbar spinal scoliosis between June 2005 and October 2010 were recruited for this retrospective study. The mean patient age at surgery was 64.
