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 [...]

Relationships between nature connection, mindfulness and wellbeing have been observed through nature based therapeutic interventions, where mindfulness and nature appear to reciprocally influence each other in relation to wellbeing and is potentially consistent with attention restoration theory. However, previous studies have relied on examining nature based interventions rather than the role of nature connection in everyday lives. This investigation explored the relationship between nature connection, mindfulness, [...]

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 [...]

Anorexia nervosa is a psychiatric disorder, the etiopathogenesis of which is still not fully understood. Currently, the most accredited model is a multifactorial model, which involves interaction between predisposing factors of biological nature, partly genetically determined, and psychological/personological and environmental socio-cultural factors. The last 20 years have led to the advancement in our knowledge on the mechanisms of energy homeostasis maintenance. There has been a veritable explosion of studies aim [...]

Biomarker surveillance after solid organ transplant is an advancing field with promise for further elucidation through high-throughput analyses and “omics” technologies. To date, Gene Expression Profiling (GEP; AlloMapâ) is the only FDA-cleared genomic assay as surveillance for moderate-severe TCMR versus allograft quiescence after heart transplantation. Clinical validity and utility, however, have been recently established after kidney and heart transplantation, for analysis of donor-derived cell-free DNA in the a [...]

Neuropsychiatric symptoms (NPS) affect nearly all persons living with dementia (PLWD) at some point during the course of the disease. Given the absence of a cure or effective pharmacotherapy for dementia, it is particularly important to prevent, measure, track, and manage NPS in dementia care. Unfortunately, these efforts are hindered by inconsistent operational definitions and measurement tools for numerous neuropsychiatric symptoms. This review examines agitation, aggression, restlessness, and rejection of care a [...]

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 [...]
