Non-Darwinian and Darwinian prokaryotic and eukaryotic evolution--an enigma in cell biology conservation.

Abstract: Our theory is embarrassingly simple. What made today's prokaryotes and modern cyanobacteria so robust is the fact that in their origin, back in the Archean (3 billion years ago), selection did not play a central role in evolution, it had only a transitory role. Asexual reproduction, mutation, drift and sampling variance in local demes were more important especially when they were accompanied by population catastrophes, where millions perished. Metazoans are generally macroscopic, sexually reproducing, ecologically specialized organisms whose history is full of extinctions and radiations leading to morphological change. On the other hand, prokaryotes, thanks to their origin, avoid extinction because as a group they have slowly evolved as generalists. Specialization appears to be less important than ecological versatility and metabolic unspecialization. Modern cyanobacteria keep on using that strategy.

Barreras de acceso a la cobertura de riesgos laborales en contratos de prestación de servicios en el sector público de salud en Bogotá

Abstract: Objective To identify access barriers to the General System for Occupational Risks (SGRL in Spanish) in a group of independent professionals (contracted with service provision contraction) in the public health sector in Bogota. Methodology Qualitative research (narrative) through interviews of four independent professionals of the Secretaria Distrital de Salud (District Health Secretariat), 4 independent professionals of Tunjuelito Hospital and 3 experts in the field of occupational risks. The content analysis paradigm was used for information analysis. Results The two institutions of the public health sector in Bogota consulted have implemented strategies that facilitate the access to the SGRL for independent professionals. However, the interviewed workers and experts identified some access barriers membership for independent workers in this occupational risk system; among these barriers are the lack of a culture of occupation risk prevention, lack of knowledge about laws and the utility of the system as well as the non-conception of the SGRL as a fundamental part of the social security system of the country. Conclusion It is necessary for the SGRL to be recognized as an integral and fundamental part of the country's social security. This depends on a cultural construction of the importance of an occupational risk system among the state organizations, employers and employees.

Características antropométricas y funcionales de corredores colombianos de élite de larga distancia

Abstract: Objective: To evaluate the anthropometric and physical performance characteristics of elite long-distance runners. Methods: A cross-sectional study in 19 male competitive long-distance runners of national level (age 28.2 ± 6.9 years). A total of 24 anthropometric variables were measured according to the International Society for the Advancement of Kinanthropometry (ISAK) statements. The Heath-Carter method and the formula proposed by Siri, Matiegka, Jackson and Pollock were used to calculate the somatotype and the body composition, respectively. Ergospirometry VO (2) max, Vertical Jump Test and the Wingate Test were used as functional indicators. Results: Regarding body composition, we found fat mass percentage 13.3 ± 3.2; muscle mass 47.3 ± 2.5%, and body adiposity index 24.1 ± 3.3. Somatotype profile was the mesomorphic-balanced (3.6-4.0-2.1). Mean values of functional tests with their standard deviations were: VO(2) max (mL•kg- 1•min-1) 42.6 ± 8.1; anaerobic power 106.0 ± 31.8 kg•s-1, and anaerobic capacity 6501.0 ± 1831.6 K/jul. Conclusion: These results may provide a profile of long-distance runners that can be used as training targets for developing athletes. The results may also provide information for training and tactical emphasis.

Physical Rehabilitation of Upper Limb in Children and Young People Through Ludic Technology

Abstract: A playful tool was developed to be used in a game activity, with characteristics of a rehabilitation therapy of upper limb, tested with 50 young people between 16 and 22 years old. The prototype consisted of a remote control and a toy car that had the function of moving in several directions (forward, back, right and left), simultaneously with the movements made by the player of extension, bending, supination and pronation of three segments of the upper limb (shoulder girdle, arm and forearm). The toy car was mobilized across a track, divided into three levels of difficulty. It was identified that the prototype complies with the requirements of an activity within the framework of rehabilitation, since the principles of the Neurodevelopment model are taken into account; there are levels of complexity that promote the acquisition, training and strengthening that may have adjacent benefits such as concentration at the cognitive level and high motivation in their social environment.
