UV Radiative Feedback During the Advanced Stages of Reionization [PDF]

, 2008
The ionizing ultraviolet background (UVB) during reionization can suppress the gas content of low-mass galaxies, even those capable of efficient atomic cooling, and thus lead to an extended reionization epoch.

Hurdles in investigating UVB damage in the putative ancient asexual Darwinula stevensoni (Ostracoda, Crustacea) [PDF]

, 2013
Ostracoda or mussel-shrimps are small, bivalved Crustacea. Because of their excellent fossil record and their broad variety of reproductive modes, ostracods are of great interest as a model group in ecological and evolutionary research.

The tiger salamander as a promising alternative model organism to the axolotl for fracture healing and regenerative biology research

The Anatomical Record, EarlyView.
Abstract Scientists have been captivated by the ability to regenerate, focusing on uncovering the mechanisms of epimorphic regeneration and applying them to human medicine. The axolotl (Ambystoma mexicanum) has become the most intensively studied model in tetrapod regeneration research, particularly concerning limb regeneration.

Clock genes regulate Ca2+ signaling and mitochondrial bioenergetics to inhibit Sjogren's disease

Arthritis &Rheumatology, Accepted Article.
Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjogren's disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA seq, and mitochondrial activity were used to investigate the effects of ...

Natural South African iron‐rich sand as a functional catalyst in hybrid photocatalytic wet peroxide oxidation technology for the degradation of methyl orange dye pollutant

The Canadian Journal of Chemical Engineering, EarlyView.
This research explored South African iron‐rich sand (SAIRS) as a natural catalyst for light‐mediated wet peroxide oxidation of methyl orange dye in wastewater and at an optimized of conditions of 3500 mg/L catalyst dose, 6 mM H2O2, and pH 2.5, SAIRS achieved 94% methyl orange degradation within 90 min under visible light.

Role of SoxE transcription factors in development and disease

Developmental Dynamics, EarlyView.
Abstract Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders.
