Using the cell-cycle control networks of the budding yeast (Saccharomyces cerevisiae) and the fission yeast (Schizosaccharomyces pombe) as examples, we first demonstrate
the correlation of this quantity with the dynamic stability of biological control networks, and then we establish a significant association between this quantity and the structural stability of the networks. And we further substantiate the generality of this approach with a broad spectrum of biological and random networks. We conclude that the regulation entropy is an effective order parameter in evaluating the robustness of biological control networks. Our work suggests a novel connection between the topological feature and the dynamic property of biological regulatory networks.”
“The aim of this study was to evaluate the effectiveness of and Autophagy inhibitor morbidity associated with the tension-free vaginal tape-secur (TVT-S) procedure in women with stress urinary incontinence (SUI).
We performed a prospective trial, examining 86 women with primary SUI. Eighty-two patients had a 1-year follow-up (dropout rate = 4.6%). The preoperative evaluation included urinalysis, urodynamic studies, and validated questionnaires. The 1-year outcome evaluation also included a 1-h pad testing.
At the 1-year
follow-up, 43 (52.4%) women were objectively cured, and 14 (17.1%) women were objectively improved. Subjectively, 49 (59.7%) patients did not experience urine loss, and 18 (22.2%) Selleck NU7441 women improved in this respect.
Postoperative de novo urge incontinence symptoms developed in 24.4% (n = 20) of patients. Vaginal defect healing occurred in 6.1% (n = 5) of patients, and one (1.2%) case of urethral erosion was reported.
Objective and subjective cure rates following TVT-S are inferior to other tape procedures.”
“MADS-domain transcription factors play pivotal roles in various developmental processes. The lack of simple loss-of-function phenotypes provides impediments to understand the biological function of some of the MADS-box transcription factors. Here we have characterized the potential role of the Arabidopsis thaliana AGAMOUS-LIKE6 (AGL6) gene by fusing full-length VS-6063 mouse coding sequence with transcriptional activator and repressor domains and suggest a role for AGL6 in lateral organ development and flowering. Upon photoperiodic induction of flowering, AGL6 becomes expressed in abaxial and proximal regions of cauline leaf primordia, as well as the cryptic bracts subtending flowers. In developing flowers, AGL6 is detected in the proximal regions of all floral organs and in developing ovules. Converting AGL6 into a strong activator through fusion to the VP16 domain triggers bract outgrowth, implicating AGL6 in the development of bractless flowers in Arabidopsis. In addition, ectopic reproductive structures form on both bracts and flowers in gAGL6::VP16 transgenic plants, which is dependent on B and C class homeotic genes, but independent of LEAFY.
