Solution of the Crow-Kimura and Eigen models for alphabets of arbitrary size by Schwinger spin coherent states [PDF]

, 2009
To represent the evolution of nucleic acid and protein sequence, we express the parallel and Eigen models for molecular evolution in terms of a functional integral representation with an $h$-letter alphabet, lifting the two-state, purine/pyrimidine assumption often made in quasi-species theory. For arbitrary $h$ and a general mutation scheme, we obtain

Dimethyl Itaconate Alleviates Escherichia coli‐Induced Endometritis Through the Guanosine‐CXCL14 Axis via Increasing the Abundance of norank_f_Muribaculaceae

Advanced Science, EarlyView.
The research findings indicate that dimethyl itaconate (DI) alleviates Escherichia coli (E. coli) induced endometritis by modulating the gut microbiota and enriching the abundance of norank_f_Muribaculaceae, thereby increasing the production of guanosine.

Efficient Synthesis of Novel Triazolo[5,1-b]purines by Diacetoxyiodobenzene-Mediated Oxidative Cyclization of Schiff Bases

Reactions
In this work, we have developed a method for synthesizing new 8-substituted triazolo[5,1-b]purines using diacetoxyiodobenzene as an oxidizing agent with good yields (59–67%).

Lie Markov models with purine/pyrimidine symmetry [PDF]

arXiv, 2012
Continuous-time Markov chains are a standard tool in phylogenetic inference. If homogeneity is assumed, the chain is formulated by specifying time-independent rates of substitutions between states in the chain. In applications, there are usually extra constraints on the rates, depending on the situation.

DISORDERS OF PURIN METABOLISM [PDF]

Journal of the American Medical Association, 1912
The old time term "uric acid diathesis" was an elastic expression, embracing such different conditions as gout, chronic rheumatism, uratic calculus, obesity and certain nephritides. In the light of more recent knowledge, the meaning of the term has been gradually narrowed until at the present time it includes only those diseases or clinical syndromes ...

Metabolomic and Cellular Mechanisms of Drug‐Induced Ototoxicity and Nephrotoxicity: Therapeutic Implications of Uric Acid Modulation

Advanced Science, EarlyView.
Drug‐induced renal damage impairs uric acid excretion, causing its accumulation in the serum, which subsequently infiltrates the cochlea. Xanthine oxidase and the ABCG2 transporter, critical in uric acid metabolism and excretion, undergo pathological changes in renal tubular and cochlear stria vascularis cells.

Synthesis of Adenine Nucleosides with a Reactive (β-Iodovinyl)sulfone or (β-Keto)sulfone Group at the C2 Position and Their Polymerase-Catalyzed Incorporation into DNA

Molecules
Iodosulfonylation of an ethynyl group at the C2 position of 2′-deoxyadenosine or adenosine with TsI provides (E)-2-(β-iodovinyl)sulfones. The latter undergo nucleophilic substitution with amines via an addition–elimination to give β-sulfonylvinylamines ...

Purine: A bi-graph based deep learning framework [PDF]

arXiv, 2014
In this paper, we introduce a novel deep learning framework, termed Purine. In Purine, a deep network is expressed as a bipartite graph (bi-graph), which is composed of interconnected operators and data tensors. With the bi-graph abstraction, networks are easily solvable with event-driven task dispatcher.

Hierarchical Regulatory Networks Reveal Conserved Drivers of Plant Drought Response at the Cell‐Type Level

Advanced Science, EarlyView.
This study presents a comprehensive multi‐omics framework to uncover cell‐type‐specific regulatory networks in plant drought responses. By integrating transcriptomic, proteomic, and epigenetic data from nearly 30 000 samples, key regulators such as CIPK23 and NLP7 are identified, revealing insights into conserved drought tolerance mechanisms and ...

A companion to the preclinical common data elements for proteomics, lipidomics, and metabolomics data in rodent epilepsy models. A report of the TASK3‐WG4 omics working group of the ILAE/AES joint translational TASK force

Epilepsia Open, EarlyView., 2022
Abstract The International League Against Epilepsy/American Epilepsy Society (ILAE/AES) Joint Translational Task Force established the TASK3 working groups to create common data elements (CDEs) for various preclinical epilepsy research disciplines.
