Analysis of cardioprotective effects using purified Saliva miltiorrhiza extract on isolated rat hearts

The purpose of the current study is to evaluate the cardioprotective effects of purified Salvia miltiorrhiza extract (PSME) on myocardial ischemia/reperfusion injury in isolated rat hearts. Hearts were excised and perfused at constant flow (7 – 9 ml · min⁻¹) via the aorta. Non-recirculating perfusion with Krebs-Henseleit (KH) solution was maintained at 37°C and continuously gassed with 95% O₂ and 5% CO₂. KH solution with or without PSME (100 mg per liter solution) was used after 30-min zero-flow ischemia for the PSME and control group, respectively. Left ventricular (LV) developed pressure; its derivatives, diastolic pressure, and so on were continuously recorded via a pressure transducer attached to a polyvinylchloride balloon that was placed in the left ventricle through an incision in the left atrium. PSME treated hearts showed significant postischemic contractile function recovery (developed pressure recovered to 44.2 ± 4.9% versus 17.1 ± 5.7%, P<0.05; maximum contraction recovered to 57.2 ± 5.9% versus 15.1 ± 6.3%, P<0.001; maximum relaxation restored to 69.3 ± 7.3% versus 15.4 ± 6.3%, P<0.001 in the PSME and control group, respectively). Significant elevation in end-diastolic pressure, which indicated LV stiffening in PSME hearts might have resulted from the excess high dose of PSME used. Further study will be conducted on the potential therapeutic value with lower dose of PSME on prevention of ischemic heart disease.

Skin hunger

Performed dusk till dawn, Friday 26 October 2007
"Skin Hunger is an improvised movement performance that invites the audience to engage directly with the performer. The performer is accompanied by a sign that invites the audience to 'touch me and see what happens'. He then uses the tactile information as a stimulus to generate movement and motivation for what he does. Small moments of relationship emerge from the initiations offered by the audience and the performer's ability to be responsive to the moment of touch.

The sign reads:

Touch me.
Touch me and see what happens.

Perhaps I will dance
Or I may do something else.

If you hit me I will bruise I do not enjoy physical pain.

Tenderness is rare.

Perceptions of change in office space design: redesigning Barwon Water’s office environment

In early 2015 Barwon Water received State government funding to rationalise and renovate its various Geelong-based administrative offices into one complex. Integral to the renovations is a new green-star retrofit of the existing Ryrie Street complex by GHD Woodhead. The project will consolidate all of Barwon Water’s offices onto one site, increase floor space, provide a new ‘green’ atrium, and adopt an open plan layout. Having set a new strategic direction, Barwon Water is now undergoing a wholesale cultural and operational change in order to realise these strategic objectives. Aspirations for workplace design have been identified as: environmentally sustainable; foster innovation and creativity; establish connections; improve communication and collaboration; provide efficient space for effective work; flexibility over time; welcoming and connected to the community; healthy; and, up to date technology. This paper investigates Barwon Water staff perceptions and apprehensions of this prospective consolidation, particularly the proposed open plan office environment. While most research in this topic is informed by an immediate pre-design workshop of staff needs, this research provides a longitudinal perspective of human perceptions about work place environment change and a review of how changes in office environment synergistically align to architectural responses and changes in corporate strategies.
