The purpose of the research was to explore the challenges, frustrations and experiences faced by young Australian adults with type 1 diabetes. We focused on the navigation of health behaviours (e.g. eating out, consuming alcohol, physical activity), which impact blood glucose levels, posing particular challenges for people with type 1 diabetes. Semi-structured interviews were conducted with 25 young adults with type 1 diabetes, between May and August 2016. Interviews were transcribed verbatim, and coded using thematic analysis. Participants reported that the experience of type 1 diabetes made simple things complicated and involved constant vigilance and control. Difficult experiences in social situations were also mentioned; participants felt that their privacy was often threatened, that people voiced misunderstandings about type 1 diabetes, and that members of the public often judge and critique their health behaviours or lifestyle choices. Simple behaviours like eating out with friends, responsible alcohol consumption, and engaging in physical activity pose particular challenges for young people with type 1 diabetes. Public education may reduce stigma and improve health behaviour.

Heat stress impairs both pollen germination and pollen tube elongation, resulting in pollination failure caused by energy imbalance. Invertase plays a critical role in the maintenance of energy homoeostasis; however, few studies investigated this during heat stress. Two rice cultivars with different heat tolerance, namely, TLY83 (heat tolerant) and LLY722 (heat susceptible), were subjected to heat stress. At anthesis, heat stress significantly decreased spikelet fertility, accompanied by notable reductions in pollen germination on stigma and pollen tube elongation in ovule, especially in LLY722. Acid invertase (INV), rather than sucrose synthase, contributed to sucrose metabolism, which explains the different tolerances of both cultivars. Under heat stress, larger enhancements in NAD(H), ATP, and antioxidant capacity were found in TLY83 compared with LLY722, whereas a sharp reduction in poly(ADP-ribose) polymerase (PARP) activity was found in the former compared with the latter. Importantly, exogenous INV, 3-aminobenzamide (a PARP inhibitor), sucrose, glucose, and fructose significantly increased spikelet fertility under heat stress, where INV activity was enhanced and PARP activity was inhibited. Therefore, INV can balance the energy production and consumption to provide sufficient energy for pollen germination and pollen tube growth under heat stress.
