Many marine invertebrates are able to regenerate lost tissue following injury, but regeneration can come at a cost to individuals in terms of reproduction, behavior and physiological condition, and can have effects that reach beyond the individual to impact populations, communities, and ecosystems. For example, removal and subsequent regeneration of clams' siphons, polychaetes' segments, and br...

Background—Barrett’s oesophagus is acquired by severe gastro-oesophageal reflux and is a premalignant condition. Acid suppression or anti-reflux surgery alone do not cause significant regression of the metaplastic mucosa nor reduce the malignant potential. Recent reports have suggested that the combination of mucosal ablation with acid suppression may result in squamous regeneration. Aims—To de...

Regeneration and gene expression of salt/drought stress tolerant Alhagi graecrum and stress sensitive Lycopersicon esculentum under different concentrations of NaCl and mannitol were studied. Mannitol and NaCl applied at concentrations of 86, 172, 256 and 43, 86, 172 mM, respectively, in a shoot regeneration medium, caused similar water potentials. In L. esculentum, regeneration was influenced ...

Impact of small rodents on mountain forest regeneration was studied in National Nature Reserve in the Beskydy Mountains (Czech Republic). A considerable amount of bark damage was found on young trees (20%) in spring after the peak abundance of field voles (Microtus agrestis) in combination with long winter with heavy snowfall. In contrast, little damage to young trees was noted under high densi...

Human periodontal ligament stem cells (hPDLSCs) transplantation represents a promising approach for periodontal regeneration; however, the cell source is limited due to the invasive procedure required for cell isolation. As human umbilical cord mesenchymal stem cells (hUCMSCs) can be harvested inexpensively and inexhaustibly, here we evaluated the regenerative potentials of hUCMSCs as compared ...

Despite the growing incidence of obesity, knowledge of how this condition, as well as associated steatosis, affects liver regeneration remains scarce. Many previous studies have used models of steatohepatitis or obesity induced by genetic alterations. In contrast, our studies on liver regeneration have focused on the effects of obesity resulting solely from high amounts of fat in the diet. This...

How should we address the increasingly prevalent condition of arterial thrombophilia? Can arterial thromboses complicate hematological diseases or the use of antithrombotic drugs? What is POC testing? Is vascular regeneration a potential shield against atherothrombotic states? This report draws insights and perspective from the discipline of hematology to answer these and other clinically relev...

Progress in existing methods of physiotherapy and body regeneration and introduction of new methods has made it possible to precisely select the techniques according to patient needs. The modern therapist is capable of improving the physical and mental condition of the patient. Watsu helps the therapist eliminate symptoms from the locomotor system and reach the psychic sphere at the same time.

In this study, the water supply in soil for wheat mother donor plants was controlled, leading to drought stress conditions, and the relative soil water content (RSWC) was measured in different soil depths. The immature embryos of common wheat (Triticum aestivum L.) 13 days post anthesis (DPA) were used to test regeneration capacity. The accumulation of the plant growth regulators (PGRs) includi...

Injured retinal ganglion cell (RGC) axons do not regenerate spontaneously, causing loss of vision in glaucoma and after trauma. Recent studies have identified several strategies that induce long distance regeneration in the optic nerve. Thus, a pressing question now is whether regenerating RGC axons can find their appropriate targets. Traditional methods of assessing RGC axon regeneration use h...
