Comparison of clinical artificial oocyte activation protocols on mouse egg activation and embryo development.

Artificial oocyte activation (AOA) with Ca2+ ionophores is an experimental procedure that benefits patients who fail to obtain fertilized eggs. However, the impact of non-physiological Ca2+ increases on cellular events involved in egg-embryo transition and early development remains poorly understood. Using the mouse model, this study compares common Ca2+ ionophore protocols applied in clinical practice - one or two exposures to A23187 or a single exposure to ionomycin - focusing on embryonic development and cellular events associated with egg activation.

Perceptual fluency affects recognition memory under deep encoding conditions promoting recollection: Evidence from an ERP study using letter-segregated method.

Perceptual fluency can increase familiarity of some of the items in recognition tests and enhance attributions of these items to the past. It is not clear, however, whether perceptual fluency can influence recognition under conditions promoting recollection-based memory. To this end, we performed a systematic replication of a study by Lucas and Paller (2013) using a letter-segregated method.

The striatum is divided into two interdigitated tissue compartments, the striosome and matrix. These compartments exhibit distinct anatomical, neurochemical, and pharmacological characteristics and have separable roles in motor and mood functions. Little is known about the functions of these compartments in humans.

Article Synopsis
- A major gene locus, SC9.1, was identified as the key regulator of brown seed color in broomcorn millet, a cereal crop known for its diverse seed colors.
- Through genetic mapping and analysis of crossbred populations, researchers found that the trait is controlled by a single dominant locus located on chromosome 9.
- The gene longmi004412 was pinpointed as the specific gene responsible for the brown seed coloration, paving the way for future advancements in crop breeding and genetic research.
