PIRSF: family classification system at the Protein Information Resource.

The Protein Information Resource (PIR) is an integrated public resource of protein informatics. To facilitate the sensible propagation and standardization of protein annotation and the systematic detection of annotation errors, PIR has extended its superfamily concept and developed the SuperFamily (PIRSF) classification system. Based on the evolutionary relationships of whole proteins, this classification system allows annotation of both specific biological and generic biochemical functions. The system adopts a network structure for protein classification from superfamily to subfamily levels. Protein family members are homologous (sharing common ancestry) and homeomorphic (sharing full-length sequence similarity with common domain architecture). The PIRSF database consists of two data sets, preliminary clusters and curated families. The curated families include family name, protein membership, parent-child relationship, domain architecture, and optional description and bibliography. PIRSF is accessible from the website at http://pir.georgetown.edu/pirsf/ for report retrieval and sequence classification. The report presents family annotation, membership statistics, cross-references to other databases, graphical display of domain architecture, and links to multiple sequence alignments and phylogenetic trees for curated families. PIRSF can be utilized to analyze phylogenetic profiles, to reveal functional convergence and divergence, and to identify interesting relationships between homeomorphic families, domains and structural classes.

Electrochemically Activated Water Catholyte for the Activation of Hydrogen Ions and ATP for Sport’s Shape and Recovery

The biological processes of a human body occur in liquid medium. The human body contains around 55-60% of water in young people. At birth the percentage is around 75%, and in elderly people it is -50-55% (by weight). The state of water in the body of athletes is an indicator for their status during physical exertion and recovery. Dehydration is a natural process developing during the period of training and football match, which influences the functioning of the locomotor, nervous, respiratory and cardio-vascular systems.The research of Ivaylo Yakimov for the period 2014-2019 from Bulgarian football players confirmed the importance of the requirement for the footballers to start physical workload optimally hydrated, in order to slow down and decrease the influence of the negative effects from the inevitable dehydration during a football match.Yakimov is а medical doctor in the football team Ludogorets.One of the co-authors considers the possibility for hydration and recovery to be done using water with hydrogen index pH over 8.5, and a negative oxidation reduction potential (ORP). The results show that footballers, who drink Catholyte water have better heart indicators compared to the ones they would have if they drink table water. Analyses are conducted of processes in ATP and mitochondria in the cell for faster achieving of maximum sports performance and recovery
