The role of Rho GTPases in facial morphogenesis

open access: yesDevelopmental Dynamics, EarlyView.
The role of small GTPases, RHOA, RAC1, and CDC42 and pathway mediators is reviewed in the context of embryonic facial development. Lip fusion requires cytoskeletal remodeling during morphogenesis of the facial processes and during lip fusion. Fnm, frontonasal mass; lnp, lateral nasal process; mnp, medial nasal process; mxp, maxillary process; np, nasal

Synthesis of rigidified flavin–guanidinium ion conjugates and investigation of their photocatalytic properties

open access: yesBeilstein Journal of Organic Chemistry, 2009
Flavin chromophores can mediate redox reactions upon irradiation by blue light. In an attempt to increase their catalytic efficacy, flavin derivatives bearing a guanidinium ion as oxoanion binding site were prepared.

To Be or Not To Be a Molecular Ion: The Role of the Solvent in Photoionization of Arginine. [PDF]

open access: yes, 2019
Application of photoionization mass spectroscopy, a technique capable of assessing protonation states in complex molecules in the gas phase, is challenging for arginine due to its fragility. We report photoionization efficiencies in the valence region of

Dasatinib and quercetin prevent alveolar bone loss in aged mice

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Recent findings have associated alveolar bone loss (ABL) with the presence of senescent cells. Aging and the accumulation of senescent cells are associated with a pro‐inflammatory environment which may exacerbate tissue damage.

Isolation of poliovirus 2C mutants defective in viral RNA synthesis [PDF]

open access: yes, 1988
Two poliovirus mutants were isolated that contain an oligonucleotide linker insertion in the 2C-coding region of the viral genome. One, 2C-31, has a strongly temperature-sensitive phenotype and the other, 2C-32, forms small plaques on HeLa cell ...

Astrocytic LRP1 mediates brain Aβ clearance and impacts amyloid deposition [PDF]

open access: yes, 2017
Accumulation and deposition of amyloid-β (Aβ) in the brain represent an early and perhaps necessary step in the pathogenesis of Alzheimer's disease (AD).

Effect of pork carnosine level on lipid and protein oxidation markers during in vitro co‐digestion in a Mediterranean meal model

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND This study assessed the effects of dietary carnosine during the in vitro digestion of a healthy meal model based on the Mediterranean diet, comprising lean pork enriched with two levels of carnosine, whole grain bread, tomato, onion, and olive oil.
