Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Derivation of gravitational time dilation from principle of equivalence and special relativity
Science & Philosophy, 2021 General relativity is the exact theory of gravity which has been experimentally found to be correct with extremely high accuracy. One of the most surprising predictions of the general theory is that time runs slow in a gravitational field.

Lorentzian theories vs. Einsteinian special relativity - a logico-empiricist reconstruction [PDF]
, 2010 It is widely believed that the principal difference between Einstein's special relativity and its contemporary rival Lorentz-type theories was that while the Lorentz-type theories were also capable of “explaining away” the null result of the Michelson ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

A física clássica de cabeça para baixo: como Einstein descobriu a teoria da relatividade especial
Revista Brasileira de Ensino de FísicaAlbert Einstein por duas vezes alterou de maneira profunda nossos conceitos de espaço e tempo com a sua teoria da relatividade: primeiro no âmbito da teoria especial de 1905 e depois com a teoria geral de 1915.

Non-linear extension of non-metricity scalar for MOND
Physics Letters B, 2020 General Relativity enjoys the freedom of different geometrical interpretations in terms of curvature, torsion or non-metricity. Within this geometrical trinity, a simpler geometrical formulation of General Relativity manifests itself in the latter, where

Time in the theory of relativity: on natural clocks, proper time, the clock hypothesis, and all that [PDF]
, 2013 When addressing the notion of proper time in the theory of relativity, it is usually taken for granted that the time read by an accelerated clock is given by the Minkowski proper time.

Relativity, Dimensionality, and Existence [PDF]
, 2007 The main purpose of this paper is to demonstrate that the analysis of the kinematical effects of special relativity holds the key to answering the question of the dimensionality of the world.

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
