Breast cancer survivors (BCSs) report decrements in cognitive functioning. A Meditative Movement (MM) program (Qigong/Tai Chi Easy) combines meditation and exercise, practices known to improve cognitive function. Method: Using a single group, pre- to post-intervention assessment design, a pilot study was conducted in BCSs to test the effects of an 8-week MM intervention on cognitive functioning, sleep and mood and to explore changes on selected gene expression factors, BDNF, NF-kB1, and TP53, expected to improve wi [...]

Over the past decade, developing geopolymer mixes to replace ordinary Portland Cement (OPC) composites has yielded positive results, leading to extensive research. The incorporation of fibers in geopolymers, besides impacting the mechanical properties, has also significantly impacted durability, mainly when dealing with the most pernicious forms of deterioration resulting from chloride attack, water penetration, sulfate attack, acid attack, as well as freeze-thaw, which occurred through chemical transgression. This [...]

Soil is a very complex medium made of minerals, organic matter, microorganisms, air, and water. Vibrational spectroscopy techniques are exceptionally well-suited to be used with portable and hand-held devices. In this study, NIR spectroscopy was applied using portable instrumentation and the holistic Aquaphotomics approach to identify the differences in three Mediterranean soil profiles from Sardinia (Italy). The soil samples (95) collected from alluvial and loess-sampling sites in the three study areas of North Sa [...]

Green synthesis of nanomaterials endeavors to reduce the use of high energy methods with those that may include lower temperatures and pressures, use of natural products, and bottom-up self-assembly. Here we describe the generation of metal-organic biohybrids (MOBs) with nanoscale features synthesized at physiological (37°C) and room temperature (25°C). These MOBs utilized the naturally occurring amino acid dimer cystine as the biological component, and a series of metals, including copper, silver, and cobalt. The [...]

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 [...]

The escalating global temperatures and their adverse effects underscore the growing imperative for the widespread adoption of clean fuels, notably hydrogen. Proton Exchange Membrane Fuel Cells (PEMFC) emerge as a pivotal green energy technology, facilitating electricity and water generation. The optimization of PEMFC efficiency hinges on the judicious selection and fabrication of polymer membranes. Within innovative materials, Zeolitic Imidazolate Frameworks (ZIFs) represent a novel subclass within the expansive fa [...]

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 [...]
