“…1-3). Our data [3][4][5][6] completely reject the assumption that the vitreous body is a homogeneous gel-like structure [9,11]. This means that physically transparent cornea, lens, and vitreous body are not transparent from histophysiological viewpoint and hence, cannot directly transmit light to the retina because of numerous "obstacles" -cell differons and fi bers.…”

Physically transparent cornea, lens, and vitreous body are not transparent from histophysiological viewpoint and hence, cannot directly transmit light to the retina. The lens forms from two primordia in the course of the eye development: ectodermal (for capsular epithelium) and neuroglia (for lenticular stroma). These data suggest that the neuroglia migrating from the internal leaflet of the ocular goblet is a source of stromal fibroblasts of the corneal proper substance and also presents the fibroblast differons in the human ocular vitreous body and in the lenticular posterior pole. The common source in the development of the stroma of the transparent structures of the eye is explained and confirmed by the fact that the cornea, lens, vitreous body, and the retinal and brain neuroglia contain special proteins common for all these structures, crystallins. The structural relationship and origin of fibroblasts of the transparent ocular media underlie the identical functions of crystallin production; the physical and chemical characteristics of crystallins prevent the diffusion of light and cumulate it in one direction. In addition, our data on the neuroglial origin of the lenticular stroma suggest that the lenticular cells can act as Muller's glia, regulating the transformed energy flow. Hence, the fibers and stromal cells of the cornea, lens, vitreous body, and retinal glia can serve as components of the universal conduction system perceiving light, transforming it into another type of energy (presumably into electromagnetic waves or some motor pulse), and only then sending it to the photosensor cells. As a result, we have one-way light conduction due to stromal cells of transparent eye structures and inability of the retina to identify these cells. We therefore conclude that the cells located in front of the retina are invisible for the photoreceptors, because they conduct stimulation being not transparent in the physical sense, but just physiologically. We see only what this unique conduction system allows us to see.

“…Solution of the visual perception problem will allow a new interpretation of the pathogenesis of such ocular diseases as glaucoma, macular degeneration, diabetic retinopathy, and cataract [2,7,[13][14][15]. Our new morphological data on the structure of human eye [3][4][5][6][7][8]14] suggest another view on the problem of visual perception.…”

“…Helicobacter infections are more frequent as the population gets older, starting to rise at the age of 40-55 years and keeping the same levels of prevalence in the elderly (Genta et al, 2017). H. pylori infection (HpI) can lead to Barrett's oesophagus, peptic ulcers, intestinal metaplasia and stomach cancer (Reva et al, 2015). Some studies have related the presence of H. pylori in the elderly with changes in plasma levels of ghrelin and in the ghrelin-to-obestatin ratio, which are known to play an important role in appetite regulation (Gao et al, 2009a;Kim et al, 2017).…”

The microbial community inhabiting our intestine, known as 'microbiota', and the ensemble of their genomes (microbiome) regulate important functions of the host, being essential for health maintenance. The recent development of next-generation sequencing (NGS) methods has greatly facilitated the study of the microbiota and has contributed to evidence of the strong influence exerted by age and diet. However, the precise way in which the diet and its components modify the functionality of the intestinal microbiome is far from being completely known. Changes in the intestinal microbiota occur during ageing, frequently accompanied by physiological changes of the digestive tract, modification of dietary patterns and impairment of the immune system. Establishing nutritional strategies aiming to counterbalance the specific alterations taking place in the microbiota during ageing would contribute to improved health status in the elderly. This review will analyse changes appearing in the intestinal microbiota from adulthood to old age and their association with dietary patterns and lifestyle factors.
