Sex Differences in Visceral Pain and Comorbidities: Clinical Outcomes, Preclinical Models, and Cellular and Molecular Mechanisms

open access: yesCells
Sexual dimorphism of visceral pain has been documented in clinics and experimental animal models. Aside from hormones, emerging evidence suggests the sex-differential intrinsic neural regulation of pain generation and maintenance.

Étude comparative de substances bioactives pour la protection des biens patrimoniaux contre les insectes ravageurs

open access: yesCeROArt : Conservation, Exposition, Restauration d'Objets d'Art, 2013
Certain heritage collections get cyclically infested by pest insects. Currently used curative treatments are punctual eradication operations, but in no way do they prevent the chronic re-infestations of sensitive cultural objects.

Rotational States of Magnetic Molecules

open access: yes, 2009
We study a magnetic molecule that exhibits spin tunneling and is free to rotate about its anisotropy axis. Exact low-energy eigenstates of the molecule that are superpositions of spin and rotational states are obtained. We show that parameter $\alpha = 2(

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Collisional decay of 87Rb Feshbach molecules at 1005.8 G

open access: yes, 2006
We present measurements of the loss-rate coefficients K_am and K_mm caused by inelastic atom-molecule and molecule-molecule collisions. A thermal cloud of atomic 87Rb is prepared in an optical dipole trap.

RAD50 missense variants differentially affect the DNA damage response and mitotic progression

open access: yesFEBS Letters, EarlyView.
RAD50 incorporates into the MRN complex and initiates the DNA damage response. Furthermore, RAD50 promotes mitotic progression. RAD50 missense variants capable of forming an MRN complex supported the DNA damage response and mitotic features to different extents in complementation experiments, indicating these functions are separable and might impact ...
