Modified Gant procedure for treatment of internal rectal prolapse in elderly women.

Background: Although rectal prolapse is not a life-threatening condition, it can cause defecation disorders, anal incontinence, sensory abnormalities, and other problems that can seriously affect quality of life.

Aim: To study the efficacy of the modified Gant procedure for elderly women with internal rectal prolapse.

Methods: Sixty-three elderly female patients with internal rectal prolapse underwent the modified Gant procedure.

The influences of canopy species and topographic variables on understory species diversity and composition in coniferous forests.

Understanding the factors that influence the distribution of understory vegetation is important for biological conservation and forest management. We compared understory species composition by multi-response permutation procedure and indicator species analysis between plots dominated by Qinghai spruce (Picea crassifolia Kom.) and Qilian juniper (Sabina przewalskii Kom.

Seasonal fluctuations and temperature dependence in photosynthetic parameters and stomatal conductance at the leaf scale of Populus euphratica Oliv.

A combined model to simulate CO₂ and H₂O gas exchange at the leaf scale was parameterized using data obtained from in situ leaf-scale observations of diurnal and seasonal changes in CO₂ and H₂O gas exchange. The Farquhar et al.-type model of photosynthesis was parameterized by using the Bayesian approach and the Ball et al.

[Expressions of neurotrophic factors and their receptors in prostate cancer].

Objective: To investigate the expressions of neurotrophic factors (NTFs) and their receptors in prostate cancer.

Methods: We detected the expressions of the nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), and their receptors TrkA, TrkB and p75 in 35 specimens of prostate cancer by Western blotting, and included 10 specimens of normal prostate tissue from young males that died accidentally.

Results: Compared with the control group, the expressions of NGF and p75 were significantly decreased (P < 0.

[Analysis of the spatial and temporal changes in soil CO2 efflux and its related factors from alpine meadow in Qilian Mountains].

Continuous field experiment was carried out on alpine meadow along different elevation gradient in Qilian Mountains during the growing season of 2004 using a soil respiration chamber (Li-6400-09) connected to a portable photosynthesis system (Li-6400). The possible effect of water-heat factors and root parameter on characteristics of alpine meadow soil respiration was statistically analyzed. The results indicate that soil CO2 efflux has apparent spatial variation laws.
