Pre‐oviposition development of the brown anole (Anolis sagrei)
Developmental Dynamics, EarlyView.Abstract Background The brown anole, Anolis sagrei, has emerged as a representative squamate species for developmental studies during the past decades. Novel functional tools have been established to manipulate embryogenesis through genome editing or the introduction of small molecule inhibitors, and their effective use requires a thorough ...

Developmental Dynamics, EarlyView.Abstract Background Mouse nodal immotile cilia mechanically sense the bending direction for left–right (L–R) determination and activate the left‐side‐specific signaling cascade, leading to increased Nodal activity. Asymmetric distribution of Pkd2, a crucial channel for L–R determination, on immotile cilia has been reported recently. However, the causal

Studies on the sperm reservoir of the pig oviduct [PDF]
, 2003 During sperm transport in the female pig a proportion of spermatozoa are arrested, often for 24 h or more, in a particular segment of the utero-tubal junction (UTJ) and the adjacent tubal isthmus, where a sperm reservoir (SR) is built up.

Environmental and Molecular Mutagenesis, EarlyView.Abstract Exposure levels without appreciable human health risk may be determined by dividing a point of departure on a dose–response curve (e.g., benchmark dose) by a composite adjustment factor (AF). An “effect severity” AF (ESAF) is employed in some regulatory contexts.

Design Principles Of Inorganic‐Protein Hybrid Materials for Biomedicine
Exploration, EarlyView.Inorganic protein hybrid materials (IPHMs) due to editable structure present unrivalled potential at the intersection of synthetic biology and materials science. The synthesis of IPHMs with a high degree of biosafety from bioactive units represents a shift in material design and synthesis.

The RNA Binding Protein Bcas2 is Required for Antibody Class Switch in Activated‐B Cells
Exploration, EarlyView.Bcas2 recruits DHX15 and SRSF7 to form a protein complex for the splicing of CSR‐related mRNA at the 5' ss and 3' ss, generating two mature mRNA isoforms, which are ultimately translated into CSR‐related proteins. These CSR‐related proteins bind to DNA associated with antibodies, affecting the DSB repair of the relevant DNA after AID induction, thereby

A Critical Overview of Common Foodborne Toxicants and Methods for Their Reliable Detection
Food Frontiers, EarlyView.ABSTRACT Food is an essential commodity for human health. However, toxicants such as mycotoxins, heavy metals, acrylamide, and pesticides can be present in food either naturally or through processing, packaging, or some anthropogenic activities. A thorough review of carefully selected studies revealed that climate change and pandemics have led to an ...
