Purpose: To compare the outcome of primary trabeculotomy with that of combined trabeculectomy-trabeculotomy (CTT) with mitomycin C (MMC) in children with congenital glaucoma.

Methods: This is a prospective comparative study, carried out on a cohort of 28 eyes (28 infants) with congenital glaucoma. Infants with proved congenital glaucoma [based on intra-ocular pressure (IOP), cup/disc (C/D ratio), corneal diameter and axial length measurements] were randomly allocated to either group A (trabeculotomy) or group B (CTT with MMC). Postoperatively, all patients were followed regularly for 3 years; for IOP and C/D evaluation. Criteria for successful outcome included resolution of corneal oedema, reversal of disc cupping, and IOP 18 mmHg or less.

Results: Success rate in each group was 85.7% (p = 1.00). All preoperative parameters, including horizontal corneal diameter, axial length, IOP and C/D ratio, were not statistically significantly different between the two groups. Also, postoperative C/D ratio, IOP, IOP difference and percentage difference (compared to preoperative values), at different follow-up visits, were not statistically significantly different between both surgical techniques. Comparing preoperative to postoperative IOP and C/D ratio in each group was statistically significant.

Conclusion: Both primary trabeculotomy and CTT with MMC had similar outcomes, which could mean that trabeculotomy could be resorted to first.

Transcriptional regulation of postnatal aortic development.

The aorta exhibits tremendous changes in geometry, composition, and mechanical properties during postnatal development. These changes are necessarily driven by transcriptional changes, both genetically programmed and mechano-responsive, but there has not been a careful comparison of time-course changes in the transcriptional profile and biomechanical phenotype. Here, we show that the greatest period of differential gene expression in the normal postnatal mouse aorta occurs prior to weaning at three weeks of age though with important evolution of many transcripts thereafter.

The biomechanics of embryonic notochords are studied using an elastic membrane model. An initial study varying internal pressure and stiffness ratio determines tension and geometric ratios as a function of internal pressure, membrane stiffness ratio, and cell packing pattern. A subsequent three-point bending study determines flexural rigidity as a function of internal pressure, configuration, and orientation.

The physical and geometric aspects of notochords are investigated using a model of finite-length notochords, with interior vacuolated cells arranged in two common packing configurations, and sheath modeled as homogeneous and thin. The key ratios governing packing patterns and eccentricity are number of cells per unit length λ and cell tension ratio Γ. By analyzing simulations that vary Γ and total number of cells N, we find that eccentricity, λ, and internal pressure approach consistent asymptotic values away from the tapering ends, as N increases.

Article Synopsis
  • - The study focuses on how organisms regulate growth to achieve their final size and shape, especially in multicellular organisms where growth must be coordinated across different tissues and organs.
  • - Using the roundworm C. elegans as a model, researchers collected extensive data on growth measurements, feeding behavior, and size changes throughout development.
  • - They proposed a model suggesting that physical constraints, specifically cuticle stretch, could inform C. elegans when to transition between developmental stages, influencing their growth rate and timing.

This paper develops a theoretical basis for the observed relationship between cell arrangements in notochords and analog physical models, and the eccentricity of their cross sections. Three models are developed and analyzed, of the mechanics of cell packing in sheaths. The key ratios governing the packing patterns and eccentricity are cells per unit length λ, tension ratio Γ, and eccentricity e.
