Synthesis, X‐Ray Analysis, Anticancer Activity, Computational, and in Silico Studies of New Thiophene Pyrazole Conjugates

open access: yesChemistryOpen, Volume 15, Issue 6, June 2026.
Two new thiophene–pyrazole derivatives, 8a and 8b, were synthesized from thiophene 3 precursor and fully characterized. The structure of 8a was confirmed by single‐crystal X‐ray diffraction, which revealed a nonplanar conformation stabilized by NH···O hydrogen bonding and weak intermolecular contacts.

Higher Genetic Diversity Across Several Small Patches Compared to a Single Large Patch: A Within‐Species Test of SLOSS

open access: yesEvolutionary Applications, Volume 19, Issue 3, March 2026.
ABSTRACT The SLOSS (Single Large or Several Small) debate is crucial in reserve design, focusing on evaluating the conservation efficacy of a single large reserve versus multiple small reserves for species preservation. While accumulating evidence suggests that multiple small reserves may conserve greater species diversity, the question of how to ...

The Discovery of a Twelfth Wolf-Rayet Star in the Small Magellanic Cloud

open access: yes, 2003
We report the discovery of a relatively faint (V=15.5) early-type WN star in the SMC. The line strength and width of He II lambda 4686 emission is similar to that of the other SMC WNs, and the presense of N V lambda 4603,19 emission (coupled with the ...

Evaluation of Off‐Label Postoperative Inhaled Steroid Use in Tracheal and Cricotracheal Resection

open access: yesOtolaryngology–Head and Neck Surgery, Volume 174, Issue 2, Page 473-478, February 2026.
Abstract Objective Tracheal resection (TR) and cricotracheal resection (CTR) are associated with anastomotic complications. Off‐label use of inhaled corticosteroids has gained popularity for reducing tracheal granulation tissue, though adoption remains limited due to unclear safety and efficacy.

The Isomerization Equilibrium between Cis and Trans Chloride Ruthenium Olefin Metathesis Catalysts from Quantum Mechanics Calculations [PDF]

open access: yes, 2005
The cis−trans chloride isomerization of a ruthenium olefin metathesis catalyst is studied using quantum mechanics (B3LYP DFT), including the Poisson−Boltzmann (PBF) continuum approximation. The predicted geometries agree with experiment.
