Cluster-set resistance training is focused on performance improvements of sports by increasing the repetition maximum, jump height, and efficiency in the sprint. In this commentary, we present relevant aspects to optimize the use of cluster training under the context of muscle hypertrophy. Therefore, we address intra-sets pauses, the number of repetitions per block, and strategies that benefit this methodology. During a cluster set resistance training program, not only the total number of repetitions could be highe [...]

This study deals with the production of zinc silicate thin films employing a solid-state reaction at temperatures ranging from 300 °C to 560 °C, to develop new inorganic, n-type materials with seemingly incompatible properties as low work function, high mobility, and high visible transmittance. Depending on a careful reaction control, zinc silicates can preserve reagents (silicon and/or ZnO) as nanoaggregate guests, exhibiting tunable light absorption and emission properties that make them useful for differ [...]

Stable levitation of systems consisting of a magnetic source and a superconductor is actively investigated due to the promising applications of this technology. While huge efforts have been made for modeling these setups with numerical simulations, analytical models, in spite of their use being limited to devices with a high degree of symmetry, can bring precious information on certain characteristics of levitating systems. Summarizing our previous work in the field, we present the mean-field model that we have pro [...]

DNA methylation is an epigenetic change that is not only important in normal cell development, but also plays a significant role in human health and disease. Therefore, studies of DNA methylation have been actively pursued to clarify the precise role of this modification in disease etiology and its potential as a biomarker of disease. One key issue in analyzing DNA methylation data is the detection of significant differences in methylation levels between diseased individuals and healthy controls. In recent years, m [...]

(3) Results: In such cases we find syndrome shifts of symptoms shifting from vital to less vital organs, from inside outside and from up downwards, e [...]

Driven exercise (i.e., the tendency to exercise in excess to influence weight/shape or regulate emotion) is difficult to manage in the context of anorexia nervosa, and is associated with poorer treatment outcomes, and psychological and medical severity. Driven exercise is observed in a considerable number of those diagnosed with anorexia nervosa; however, to date, this hallmark symptom remains poorly understood. Dopamine signaling is implicated in motivating and maintaining appetitive behavior among patients with e [...]

Is it ethically permissible to sacrifice the life of one human being in order to save the lives of five others? This question forms the basis of the famous thought experiment called “the trolley problem.” Surveys have found that 90 percent of people agree it is permissible when the victim to be sacrificed is described as off in the distance, whereas the opposite result occurs if the victim is described as up close. No consistent ethical principle has been identified that account for these results. In this paper we [...]

Wheat bran cereals are an important source of dietary fibre. The aim of the study was to investigate if a high intake (120 g) of fibre rich breakfast cereal (which delivers the UK Government guidelines for fibre intake in one serving but is three-fold higher than the manufacturers recommended serving) has additional potential health benefits compared to the recommended serving (40 g, containing 11 g of dietary fibre). To assess this, the study determined the short chain fatty acid (SCFA) profiles in human faecal, u [...]

Thrombotic Microangiopathy (TMA) is a syndrome characterized by microangiopathic hemolytic anemia (MAHA) and thrombocytopenia. The presence of schistocytes on peripheral smear, a negative Coombs test, elevated lactate dehydrogenase, increased reticulocyte count and low haptoglobin are often the clues for MAHA. The microvascular process often targets vasculature in kidneys, brain, gastrointestinal system, heart, and skin. A timely diagnosis and treatment are often crucial to prevent severe end organ damage and death [...]
