Lamellar and inverse micellar structures of skin lipids: Effect of templating [PDF]

open access: yes, 2014
The outermost layer of skin, the stratum corneum (SC), comprises rigid corneocytes in a layered lipid matrix. Using atomistic simulations we find that the equilibrium phase of the SC lipids is inverse micellar.

Hydrochlorides, hydrates, hydronitrate, and an unanticipated hydrolysis product of famotidine

open access: yesActa Crystallographica Section C, Volume 82, Issue 5, Page 241-249, May 2026.
The structures of a new polymorph of famotidine hydrochloride, a famotidine hydrochloride hydrate, a new hydronitrate salt of famotidine, and an unexpected hydrolyzed complex of famotidine are reported. The famotidine hydrochloride hydrate and the hydrolyzed famotidine hydrochloride have Z′ values of 2 and 4, respectively.This article contributes to ...

Smart Materials for Dirty Waters: Reversible Aerogels Unlock Closed‐Loop Heavy Metal Remediation

open access: yesSmall Science, Volume 6, Issue 4, April 2026.
Reversible chitosan–lignin aerogels are developed for efficient heavy metal removal (Cu2+, Pb2+, and Zn2+) from contaminated water, combining high adsorption capacity, recyclability, solvents, and pH stability. The aerogels also demonstrate catalytic activity in Chan–Lam crosscoupling reactions, showcasing their potential for sustainable water ...

A Novel Topical Emollient Plus for Canine Atopic Dermatitis: A Clinical Trial Assessing Efficacy and User Acceptance

open access: yesVeterinary Dermatology, Volume 37, Issue 2, Page 293-305, April 2026.
Background: Canine atopic dermatitis (cAD) is a common, chronic skin condition characterised by epidermal barrier dysfunction, immune dysregulation and cutaneous dysbiosis. While “emollient plus” formulations are widely used in human atopic dermatitis, their role in cAD remains underexplored. Hypothesis/Objectives: To evaluate the clinical efficacy and

Three-nucleon force at large distances: Insights from chiral effective field theory and the large-N_c expansion

open access: yes, 2014
We confirm the claim of Ref. [D.R. Phillips, C. Schat, Phys. Rev. C88 (2013) 3, 034002] that 20 operators are sufficient to represent the most general local isospin-invariant three-nucleon force and derive explicit relations between the two sets of ...

Use of a Cytobrush for Sampling the Ear Canal of Dogs With Otitis Externa

open access: yesVeterinary Dermatology, Volume 37, Issue 2, Page 227-235, April 2026.
Cytological examination of the ear canal is essential for evaluating dogs with otitis externa (OE). The conventional sampling method uses a swab. However, the cytobrush (gynaecological cervical brush), already used for cytological collection from other anatomical sites, has not been adequately investigated for this purpose in dogs with OE.
