Inadequate sleep is a largely under recognised problem in Australia despite researchers consistently highlighting it as a key component of health and wellbeing. Over a third of Australian adults now experience some form of inadequate sleep, which is consistently linked to a range of accompanying physical and mental health concerns. In addition to the health burden on the individual, the associated financial burden incurred by the community is extremely high with inadequate sleep costing over 66.3 billion annually i [...]

The objective of the paper is twofold: first, to review the classical diffusion models and show the approximations at the origin of the parabolic character of the classical equations; second, to demonstrate a connection between the quantum and classical models of diffusion. As diffusion is inherently related to the motion of constituents, the consistent models are framed within the dynamics of mixtures. The derivation of diffusion equations is then determined based on the related, pertinent approximations.

Following post-operative treatment, the vast majority of GBMs recur, usually within 2 cm of the tumor resection margin. Since these tumors seldom metastasize outside the CNS, improved localized therapies should prove beneficial. Drug delivery systems (DDS) that allow control over drug release by an externally applied energy, such as light, have the potential of improving the results of chemotherapy. Light-activated hydrogel DDS, implanted in the operative cavity formed by tumor resection, bypasses the blood brain b [...]

Globally between 30-40% of all osteoporotic fractures occur among men, with a quarter of all hip fractures, the most serious complication of osteoporosis, occurring in men. Among men of 50 years of age or older, osteoporotic fracture risk reaches an alarming 20%. What is of great concern is that associated mortality is greater among men when compared with women. For hip fractures specifically, mortality for men is two to three times that in women which may be attributed to the fact that osteoporosis is often consid [...]

Hansemann-Boveri’s aneuploidy theory, the Warburg effect, and the Knudson hypothesis can be viewed as different aspects of a single theory of cancer. In this, the extremely common chromosome missegregation may be the underlying cause. Chromosome missegregation is mitigated via several mechanisms. Cancer can occur only when all of these mechanisms have been inactivated in a single cell line, typically by mutation. There are at least five different repair mechanisms, implying a hit-factor of at least five. These miti [...]

Myokines are cytokines secreted from muscle during contraction and are implicated in autocrine, paracrine, and endocrine regulation of biological systems. It is postulated that myokines contribute to skeletal muscle adaptations in response to resistance exercise. Exercise, including resistance exercise, is an important factor in the management of maintaining skeletal muscle strength, mass, and function with aging. Sarcopenia is exacerbated with increased age and therefore, it is important to understand the potentia [...]
