The supplement telomerase activator TA-65 (purified from Astragalus membranaceus) has been shown to retard cellular senescence, boost the aging immune system, and retard age-related symptoms. Lengthened telomeres retard aging, but because cancers often maintain longevity by lengthening telomeres, dietary telomerase activator might possibly increase tumorigenesis. This study investigated whether oral TA-65 effects the timing of onset and/or the incidence of skin cancers induced by UVB-irradiation and whether that po [...]

Neuroprotection in glaucoma is any medical treatment by which decline in visual function can be slowed or prevented by supporting the health and survival of neural cells, independent of lowering of intraocular pressure (IOP). This is achieved by targeting mechanisms to inhibit or delay retinal ganglion cell death and promote cell survival pathways. Despite demonstrating promising results in preclinical trials, many neuroprotective strategies have failed to show success in subsequent clinical trials. Of the clinical [...]

Thirty years ago, Tom Kitwood proposed a change in the care of people with dementia, from ‘warehousing’ to ‘person-centred care’. The change had noticeable benefits for those with dementia. Kitwood set out his presuppositions for this change. For example, Kitwood understood personhood as the standing or status bestowed on one human being by others in the context of relationships and social being and held that respect for the absolute value of each person is a key theme in Western ethical discourse. He was clear thi [...]

This article describes the development of a novel ironmaking technology based on flash reduction. The development started with the proof of the kinetic feasibility, considering that a typical flash reactor provides only a few seconds of residence time. This was followed by tests in a laboratory flash reactor and finally a pilot plant operation. The rate equations formulated in this work were developed considering the optimum combination of temperature, residence time, and reducing gas partial pressure to achieve &# [...]

Adipose tissue is distributed throughout the body as fat depots. The amount of adipose tissue increases with age. In mice, epididymal fat depots in males and gonadal fat depots in females are associated with the reproductive system. Regarding fat depots in females, the adipose tissue under the skin can be easily exposed via surgery when the ovary, oviduct, and uterus are pulled out and exposed. As handling adipose tissue is relatively easy, adipocytes might be good targets for genetic manipulation (including gene d [...]

Hydrogen (H2) shows great promise as zero-carbon emission fuel, but there are several challenges to overcome in regards to storage and transportation to make it a more universal energy solution. Gaseous hydrogen requires high pressures and large volume tanks while storage of liquid hydrogen requires cryogenic temperatures; neither option is ideal due to cost and the hazards involved. Storage in the solid state presents an attractive alternative, and can meet the U.S. Department of Energy (DOE) constraints to find m [...]
