Responses of Low-Quality Soil Microbial Community Structure and Activities to Application of a Mixed Material of Humic Acid, Biochar, and Super Absorbent Polymer.

Low-quality soil for land reuse is a crucial problem in vegetation quality and especially to waste disposal sites in mining areas. It is necessary to find suitable materials to improve the soil quality and especially to increase soil microbial diversity and activity. In this study, pot experiments were conducted to investigate the effect of a mixed material of humic acid, super absorbent polymer and biochar on low-quality soil indexes and the microbial community response.

Expression of miR-34a in basal cell carcinoma patients and its relationship with prognosis.

Purpose: To investigate the relationship between the expression level of miR-34a in the serum of basal cell carcinoma patients and the clinical prognosis.

Methods: Eighty-six patients with basal cell carcinoma who underwent surgery from July 2011 to July 2013 were enrolled in the experimental group, and 85 healthy volunteers were selected from the physical examination department of Henan Province Luoyang Orthopedic Traumatological Hospital to serve as control group. Real-time PCR was used to detect the expression of miR-34a in the serum of the study subjects.

Combined anterior-to-posterior and posterior-to-anterior approach to paranasal sinus surgery: an update.

Objectives: To develop an anatomically and functionally based approach to endoscopic intranasal ethmoidectomy; to develop such an approach using the salient features of the anterior-to-posterior (AP) and posterior-to-anterior (PA) intranasal sinus operations; to assess the safety of this form of ethmoidectomy in a patient population.

Study Design: Retrospective chart review of patients undergoing ethmoidectomy by the authors or by residents under their direct supervision.

Setting: University teaching hospital.

Objective computerized versus subjective analysis of facial synkinesis.

Objectives/hypothesis: To compare the sensitivity of an objective, computerized approach to measurement of facial synkinesis with that for a subjective approach and to examine the test-retest reliability of these approaches.

Study Design: Prospective, nonrandomized, and blinded.

Methods: Remote facial motion at the upper eyelids and oral commissures during a closed-lip smile and eyelid closure were measured using a commercially available computerized motion analysis system.
