Oocytes recovered from cows treated with retinol become unviable as blastocysts produced in vitro [PDF]

open access: yes, 2011
Retinoids have been shown to enhance developmental competence of the oocyte in cattle, sheep and pigs. In this study we investigated whether exogenous retinol stimulates the bovine oocyte during its intrafollicular growth and the time limits of exposure ...

Investigating transthyretin variants H88R and I107V in amyloid priming: From destabilization to complete dissociation

open access: yesThe FEBS Journal, EarlyView.
Investigated mutations in transthyretin (TTR) disrupt the F87‐centered hydrophobic core that stabilizes its tetrameric structure. The mild I107V mutation weakens inter‐chain packing, while H88R fully abolishes tetramer formation, yielding a monomeric, aggregation‐prone form. Structural, biophysical, and computational analyses reveal that both mutations

Retinal Pigment Epitheliopathy due to Sub-Optimal Recycling of Vitamin A (RESORVA): A Novel RDH11 -Related Phenotype. [PDF]

open access: yesClin Genet
RDH11 is a minor isoenzyme that catalyses the oxidation of 11‐cis‐retinol to 11‐cis‐retinal in the retinal pigment epithelium, alongside RDH5 and RDH10. Biallelic null variants in RDH11 lead to upregulation of RDH5 and RDH10 (transcriptional adaptation), maintaining 11‐cis‐retinal bioavailability, but still causing Retinal Pigment Epitheliopathy due to

Degradomics for large‐scale mechanistic insights on proteases and proteolysis in human health

open access: yesThe FEBS Journal, EarlyView.
Proteolysis has an important role in human disease but remains relatively unexplored. Degradomics, the uncovering of proteolysis in tissues, cells, and proteins, uses mass spectrometry‐based terminomics to identify protein termini occurring therein (forward degradomics) and to define the actions of proteases (reverse degradomics).

Evaluating the suitability of six hydrophobic natural eutectic solvents as the internal phase in a cosmetic cream formulation

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Hydrophobic natural eutectic solvents can function as structural oil phase substitutes in creams prepared by low‐energy processes, enabling sustainable, regulation‐compliant formulations with desirable sensory profiles. Abstract Objective This work evaluates whether hydrophobic natural eutectic solvents can replace the conventional oil phase in ...
