Previous research has suggested that numerosity estimation and counting are closely related to distributed and focused attention, respectively (Chong & Evans, WIREs Cognitive Science, 2(6), 634-638, 2011). Given the critical role of color in guiding attention, this study investigated its effects on numerosity processing by manipulating both color variety (single color, medium variety, high variety) and spatial arrangement (clustered, random). Results from the estimation task revealed that high color variety led to a perceptual bias towards larger quantities, regardless of whether colors were clustered or randomly arranged.

Uterine Deletion of Impairs Placental Vascularization and Induces Intrauterine Fetal Death in Mice.

Int J Mol Sci

July 2022

Division of Animal Disease Model, Research Center for Experimental Modeling of Human Disease, Kanazawa University, Takaramachi 13-1, Kanazawa 920-8641, Japan.

Article Synopsis
  • The expression of certain clock genes was found to be lower in the endometrium of women with recurrent spontaneous abortions, hinting at their importance in pregnancy.
  • Researchers created mice with specific deletions of uterine clock genes (cKO mice), which could implant embryos but failed to maintain a pregnancy due to suppressed function of uterine NK cells and poor placental vascular formation.
  • Progesterone treatment was able to sustain some pregnancies in cKO mice, promoting the recruitment of beneficial CD161-positive NK cells, but it did not fix the structural issues within the placenta, highlighting the role of the uterine clock system in maintaining pregnancy post-implantation.

Happiness is a valuable experience, and societies want their citizens to be happy. Although this societal commitment seems laudable, overly emphasizing positivity (versus negativity) may create an unattainable emotion norm that ironically compromises individual well-being. In this multi-national study (40 countries; 7443 participants), we investigate how societal pressure to be happy and not sad predicts emotional, cognitive and clinical indicators of well-being around the world, and examine how these relations differ as a function of countries' national happiness levels (collected from the World Happiness Report).

Inadequate dietary habits in youth are known to increase the risk of onset of various diseases in adulthood. Previously, we found that female college students who skipped breakfast had higher incidences of dysmenorrhea, suggesting that breakfast skipping interferes with ovarian and uterine functions. Since dietary habits can be managed by education, it is preferable to establish a convenient screening system for meal skipping that is associated with dysmenorrhea as part of routine services of health service centers.

There are growing concerns that poor dietary behaviors at young ages will increase the future risk of chronic diseases in adulthood. We found that female college students who skipped breakfast had higher incidences of dysmenorrhea and irregular menstruation, suggesting that meal skipping affects ovarian and uterine functions. Since dysmenorrhea is more prevalent in those with a past history of dieting, we proposed a novel concept that inadequate dietary habits in adolescence become a trigger for the subsequent development of organic gynecologic diseases.

Embryo implantation in the uterus is an essential process for successful pregnancy in mammals. In general, the endocrine system induces sufficient embryo receptivity in the endometrium, where adhesion-promoting molecules increase and adhesion-inhibitory molecules decrease. Although the precise mechanisms remain unknown, it is widely accepted that maternal-embryo communications, including embryonic signals, improve the receptive ability of the sex steroid hormone-primed endometrium.
