A Novel Antioxidant Peptide Cath‐Np Derived from Nanorana parkeri Attenuates UVB‐Induced Skin Photodamage in Mice

open access: yesIntegrative Zoology, EarlyView.
Schematic representation of Cath‐Np as an antioxidant suppressing acute skin damage caused by ultraviolet B (UVB) radiation in mice. Cath‐Np inhibits the activation of p53 and mitogen‐activated protein kinase pathways while it activates the Nrf2 pathway by its strong antioxidant effects, and accordingly suppresses the expression of inflammatory factors

Reionization in Technicolor

open access: yes, 2018
We present the Technicolor Dawn simulations, a suite of cosmological radiation-hydrodynamic simulations of the first 1.2 billion years. By modeling a spatially-inhomogeneous UVB on-the-fly with 24 frequencies and resolving dark matter halos down to $10^8

Low Sunscreen Awareness and Misconceptions in Skin of Colour With Acne‐Related Post‐Inflammatory Hyperpigmentation: A Cross‐Sectional Study Highlighting the Need for Targeted Education

open access: yesAustralasian Journal of Dermatology, EarlyView.
ABSTRACT Background/Objectives Post‐inflammatory hyperpigmentation (PIH) is a frequent sequela of acne in patients with skin of colour (SOC). While sunscreen is widely recommended for PIH prevention, little is known about real‐world sunscreen practices in this group. This study aimed to evaluate sunscreen use, barriers and factors influencing adherence

Time-resolved X-Shooter spectra and RXTE light curves of the ultra-compact X-ray binary candidate 4U 0614+091

open access: yes, 2012
In this paper we present X-Shooter time resolved spectroscopy and RXTE PCA light curves of the ultra-compact X-ray binary candidate 4U 0614+091. The X-Shooter data are compared to the GMOS data analyzed previously by Nelemans et al. (2004).

Nature of Chemisorption on Titanium Carbide and Nitride

open access: yes, 2005
Extensive density-functional calculations are performed to understand atomic chemisorption on the TiC(111) and TiN(111) surfaces, in particular the calculated pyramid-shaped trends in the adsorption energies for second- and third-period adatoms.

Changes in the microbiome and metabolome in captive red kangaroos (Osphranter rufus) affected by macropod progressive periodontal disease

open access: yesAustralian Veterinary Journal, EarlyView.
Macropod progressive periodontal disease (MPPD) is a severe oral condition frequently observed in captive macropods, particularly red kangaroos (Osphranter rufus), yet its underlying biological features remain poorly understood. In this exploratory descriptive study, we investigated oral and fecal microbiomes and metabolomic profiles in captive red ...

Wells syndrome: clinical findings and management in a large cohort of 48 patients

open access: yesJDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Background and Objectives: Wells syndrome (WS) is a rare inflammatory skin disorder typically characterized by erythematous, edematous, and pruritic plaques. Despite its distinct histopathological features, WS remains an underdiagnosed disease due to its variable clinical presentations and overlap with other dermatological conditions.

Afamelanotide improves quality of life and light tolerance in Austrian erythropoietic protoporphyria patients

open access: yesJDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Background Erythropoietic protoporphyria (EPP) is a rare genetic disorder characterized by severe phototoxic reactions that occur within minutes of light exposure. In clinical studies, afamelanotide has been shown to prolong pain‐free sun exposure, improve quality of life, and reduce the frequency and severity of phototoxic reactions ...
