Introduction: Renal Failure (RF) is a worldwide public health problem with a constantly increasing prevalence. Hemodialysis is a therapeutic method of treatment for more than 250,000 patients with chronic kidney disease (CKD) in Europe. The numbers of new patients undergoing dialysis treatment in the 25 countries of the European Union are estimated to be 63,000 per year. Patients undergoing dialysis have poor physical fitness, fatigue, cardiorespiratory problems, mental disorders, severe functional limitations and poor quality of life. Within the literature there are several studies encompassing exercise are reported in patients with Renal Insufficiency. The aim of the present study is 1) to investigate the applicability of systematic exercise programs in patients with CKD and 2) to record the possible therapeutic effects of exercise. Methods: A systematic review of the literature using MEDLINE, EMBASE, Googlescholar, Cohrane databases was performed. Studies were selected using inclusion and exclusion criteria. We included only those studies that: Assessed exercise protocols for more than 8 weeks in adults and were randomized control trials (RCT) written in English. Results. The search resulted in 94 articles, 51 of which were not RCTs presenting the findings of 43 articles. In the remaining 43 trials exercises were performed for cardiopulmonary rehabilitation, combined resistance exercises and aerobic exercise, only resistance exercises, yoga. There were programs conducted by therapist supervision while others not. The duration of training varied from 20 minutes to 110. The results showed that patients with CKD can greatly benefit from regular exercise. Conclusions. Exercise training in adults may reduce mortality rates and improve quality of life in adult patients with chronic kidney disease. Efforts to introduce exercise training to these patients may be clinically beneficial.

The intuitiveness of gestural devices offers great potential for more physical ways of interacting, but it is imperative that such devices comply with existing, platform-independent usability principles that have proven their effect in heterogeneous settings over the last decades. This study focuses on iPhone, one of the most widely used haptic devices and reviews the usability problems of five built-in iPhone applications documented in related sources. The study investigates whether these problems are actually reported during testing with novice users, which is their severity and whether testing reveals additional issues. Overall, the study confirmed the list of usability problems documented and stressed the importance of conforming to established usability principles. © 2014 Taylor & Francis.

In order to conserve and culture the cichlid fish Archocentrus nigrofasciatus, more information about its reproductive biology and its larval behavior and morphogenesis is necessary. Currently, temperatures ranging from 21 to 27 °C are used in ornamental aquaculture hatcheries. Lower temperatures are preferred to reduce the costs of water heating, and 23 °C is usually the selected temperature. However, there is limited information on culturing protocols for ornamental species and most of the information generated on this topic remains scarce. Thus, the present study examines the morphological development of Archocentrus nigrofasciatus during the yolk-sac period up to the age of 100 h post-hatching in relation to 2 temperature regimes used in ornamental aquaculture: a temperature of 27 °C (thermal optimum) and a decreased temperature of 23 °C (thermal tolerance). The results of this study suggest that the 27 °C temperature generates intense morphological changes in yolk-sac development in a shorter period. This has advantages as it reduces the time of yolk-sac larval development, and, thus, minimizes the transition phase to exogenous feeding and maximizes the efficiency at which yolk is converted into body tissues. The present paper provides necessary information to produce freshwater ornamental fish with better practices so as to increase larval survival and capitalize on time for growth. © 2015 International Society of Zoological Sciences, Institute of Zoology/Chinese Academy of Sciences and Wiley Publishing Asia Pty Ltd.
