Role of Weak Molecular Interactions in the Mechanism of Action of a Series of Antihelmintics
Molecules, 2000 Different physicochemical properties such as solute-solute and solute-solvent interactions, tautomerism, lipophilicity and solubility in water were determined for a serie of 6,7-diaryl-pteridines in order to relate those properties with their nematocide ...

Soluble Fas ligand and neopterin in patients with systemic and cutaneous discoid lupus erythematosus
Pteridines, 2000 Evidence accumulates suggesting that the pathogenesis in systemic lupus erythematosus (SLE) is associated with modulations in the Fas/FasL system. Serum concentrations of soluble Fas ligand (sFasL) were found to be elevated in patients with SLE.

Electrochemical Hydrogenation of N‐Heterocycles and Related Substrates: A Mini‐Review
Electrochemical Science Advances, Volume 5, Issue 4, August 2025.ABSTRACT Catalytic hydrogenation refers to the (often) metal‐mediated addition of dihydrogen (H2) equivalents to unsaturated compounds to form new element‐hydrogen bonds. This conceptually simple reaction is ubiquitous in the production of a vast number of essential chemicals.

Molecular Ecology, Volume 34, Issue 15, August 2025.Abstract Colour signals play pivotal roles in different communication systems, and the evolution of these characters has been associated with behavioural ecology, integumentary production processes and perceptual mechanisms of the species involved. Here, we present the first insight into the molecular and histological basis of skin colour polymorphism ...

Insect Conservation and Diversity, Volume 18, Issue 4, Page 593-603, July 2025.The increase in urban lands and the vegetation loss implies changes in the colour of the background which in turn could cause changes in the coloration of individuals. We measured changes in body lightness of damselflies through 19 sites in Central Mexico, with a different degree of urbanisation and a different percentage of native vegetation. We found

Synthesis of 6-Hydroxymethylpterin α- and β-D-Glucosides [PDF]
, 2010 The key precursor, N(2)-(N,N-dimethylaminomethylene)-6-hydroxymethyl-3-[2-(4-nitrophenyl)ethyl]pterin (11) was efficiently prepared from 2,5,6-triamino-4-hydroxypyrimidine (8) in 5 steps.

Journal of Fish Diseases, Volume 48, Issue 7, July 2025.ABSTRACT A 10‐month‐old intact male blue Siamese fighting fish (Betta splendens) was presented to the Purdue University Small Animal Hospital with multiple bilateral masses on the caudal flank. Comprehensive evaluation using impression cytology, histopathology and transmission electron microscopy (TEM) revealed a tumour composed of a mixed‐cell ...
