Resolving the design principles that control postnatal vascular growth and scaling.

After birth, tissues grow continuously until reaching adult size, with each organ exhibiting unique cellular dynamics, growth patterns, and (stem or non-stem) cell sources. Using a suite of experimental and computational multiscale approaches, we found that aortic expansion is guided by specific biological principles and scales with the vertebral column rather than animal body weight. Expansion proceeds via two distinct waves of arterial cell proliferation along blood flow that are spatially stochastic, yet temporally coordinated.

A TBX2-driven signaling switch from androgen receptor to glucocorticoid receptor confers therapeutic resistance in prostate cancer.

Recent studies suggest that glucocorticoid receptor (GR) activation can cause enzalutamide resistance in advanced prostate cancer (PCa) via functional bypass of androgen receptor (AR) signaling. However, the specific molecular mechanism(s) driving this process remain unknown. We have previously reported that the transcription factor TBX2 is over-expressed in castrate-resistant prostate cancer (CRPC).

Operational Distal Shoe Appliance for Harmonious Occlusion: A Case Report.

Unlabelled: Preserving deciduous teeth till their natural exfoliation is important to maintain arch length in different dentition periods. Premature loss of primary teeth may cause discrepancy in arch length due to drifting of teeth and supraeruption of the opposite teeth, thereby hindering the development of a harmonious, functionally and esthetically acceptable dentition. This article describes the fabrication and clinical application of a modified functional distal shoe appliance used due to pathological obliteration of the primary/deciduous mandibular second molar prior to the eruption of the permanent mandibular first molar.

Australian outcomes from heart transplantation in the machine perfusion era.

Background: In the current era of heart transplantation, machine perfusion strategies are emerging as potential additions to the armamentarium of a transplant unit. Donation after circulatory death (DCD) donor hearts assessed through normothermic machine perfusion (NMP) has helped expand the donor pool. Hypothermic machine perfusion (HMP) is emerging as an alternative strategy to traditional static cold storage (SCS) when a prolonged ischemic time is anticipated in brain dead (BD) donors, this is important in Australia where long distant procurement is vital.

Ties that bind: understanding One Health networks and participation for zoonoses prevention and control in India.

Background: Cross-sectoral collaborations as exemplified by the One Health approach, are widely endorsed as pragmatic avenues for addressing zoonotic diseases, but operationalisation remain limited in low-and-middle income countries (LMICs). Complexities and competing interests and agendas of key stakeholders and the underlying politico-administrative context can all shape outcomes of collaborative arrangements. Evidence is building that organised collaborations are complex political initiatives where different objectives; individual and institutional agendas need to be reconciled to incentivise collaborations.
