AbstractDifferent current ideas on the origin of life are critically examined. Comparison of the now fashionable FeS/H2S pyrite-based autotrophic theory of the origin of life with the heterotrophic viewpoint suggest that the later is still the most fertile explanation for the emergence of life. However, the theory of chemical evolution and heterotrophic origins of life requires major updating, which should include the abandonment of the idea that the appearance of life was a slow process involving billions of years. Stability of organic compounds and the genetics of bacteria suggest that the origin and early diversification of life took place in a time period of the order of 10 million years. Current evidence suggest that the abiotic synthesis of organic compounds may be a widespread phenomenon in the Galaxy and may have a deterministic nature. However, the history of the biosphere does not exhibits any obvious trend towards greater complexity or «higher» forms of life. Therefore, the role of contingency in biological evolution should not be understimated in the discussions of the possibilities of life in the Universe.

Infection of newborn mice with Moloney leukemia virus (M-MuLV) causes a T-cell differentiation block in the thymic cortex accompanied by proliferation and accumulation of prethymic lymphoblasts in the thymus and subsequent spreading of these cells to generate systemic lymphoma. Current evidence shows that thymic reticular epithelial cells (REC) provide a microenvironment necessary for the maturation of prethymic lymphoblasts to mature T-lymphocytes by secretion of various thymic factors. A change in that environment due to infection of REC by virus could be decisive for the failure of lymphoblasts to mature and thus contribute to lymphoma development.We have studied the morphology and distribution of the major thymic cell populations at different stages of tumorigenesis in Balb/c mice infected when newborn with 0.2ml M-MuLV suspension, 6.8 log FFU/ml. Thymic tissue taken at 1-2 weekly intervals up to tumor development was processed for light and electron microscopy, using glutaraldehyde-OsO4fixation and Epon-Araldite embedding.

Purpose Person-centered care shifts the focus of treatment away from the traditional medical model and moves toward personal choice and autonomy for people receiving health services. Older adults remain a priority for person-centered care because they are more likely to have complex care needs than younger individuals. Even more specifically, the assessment and treatment of swallowing disorders are often thought of in terms of setting-specific (i.e., acute care, skilled nursing, home health, etc.), but the management of dysphagia in older adults should be considered as a continuum of care from the intensive care unit to the outpatient multidisciplinary clinic. In order to establish a framework for the management of swallowing in older adults, clinicians must work collaboratively with a multidisciplinary team using current evidence to guide clinical practice. Private practitioners must think critically not only about the interplay between the components of the evidence-based practice treatment triad but also about the broader impact of dysphagia on caregivers and families. The physical health and quality of life of both the caregiver and the person receiving care are interdependent. Conclusion Effective treatment includes consideration of not only the patient but also others, as caregivers play an important role in the recovery process of the patient with swallowing disorders.
