The arrow of time: from universe time-asymmetry to local irreversible processes

, 2007
In several previous papers we have argued for a global and non-entropic approach to the problem of the arrow of time, according to which the ''arrow'' is only a metaphorical way of expressing the geometrical time-asymmetry of the universe.

Substrate specificity of Burkholderia pseudomallei multidrug transporters is influenced by the hydrophilic patch in the substrate‐binding pocket

FEBS Letters, EarlyView.
Multidrug transporters BpeB and BpeF from the Gram‐negative pathogen Burkholderia pseudomallei have a hydrophilic patch in their substrate‐binding pocket. Drug susceptibility tests and growth curve analyses using an Escherichia coli recombinant expression system revealed that the hydrophilic patches of BpeB and BpeF are involved in the substrate ...

Mild encephalopathy with reversible lesions in the splenium of corpus callosum and bilateral cerebral deep white matter in identical twins

Pediatric Reports, 2016
Identical twin brothers developed mild encephalopathy at the age of 7.0 and 9.7 years (Patient 1) and 10.7 years (Patient 2). Patient 1 had influenza A at the time of his second episode, but triggering agents were not evident at the first episode.

Function‐driven design of a surrogate interleukin‐2 receptor ligand

FEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Income, Schooling, and Ability: Evidence from a New Sample of Identical Twins [PDF]

We develop a model of optimal schooling investments and estimate it using new data on approximately 700 identical twins. We estimate an average return to schooling of 9 percent for identical twins, but estimated returns appear to be slightly higher for ...

Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Simultaneous Alopecia Areata in Identical Twins: First Case Reported in Saudi Arabia

Journal of Dermatology and Dermatologic Surgery
Alopecia areata (AA) is an autoimmune dermatosis that causes nonscarring hair loss on the scalp and/or body. Although AA has been identified as a polygenic disease, environmental factors are thought to be a major pathogenetic trigger for AA.

Epigenetic Basis of Twin Discordance in Diseases: Future Benefits

Gynecology Obstetrics & Reproductive Medicine, 2018
Monozygotic twins share the same genotype since they are derived from the same zygote. However, monozygotic (MZ) twin siblings frequently present many phenotypic differences, such as their susceptibilities to diseases.

Does education reduce the probability of being overweight? [PDF]

This paper analyses the causal effect of education on the probability of being overweight by using longitudinal data of Australian identical twins. The data include self-reported and clinical measures of body size.
