Studying caregiver-infant co-regulation in dynamic, diverse cultural contexts: A call to action.

Infant Behav Dev 2021 Jun 9;64:101586. Epub 2021 Jun 9.

University of California, Davis, United States.

Caregivers and infants co-regulate their physiology, emotions, and behavior in a way that is dynamically responsive to each other and the contexts in which they live. This paper is an introduction and call to action for researchers interested in understanding how to study caregiver-infant interactions in the home and diverse cultural contexts, including marginalized communities. We argue that research will be more valid, culturally relevant, and tapped-in to the daily lives of caregivers and infants if there is partnership and collaboration with the caregivers in the design of the questions, data collection and analysis, and distribution of the findings.

I did not expect to be dreaming: Explaining realization in lucid dreams with a Bayesian framework.

Authors:
Piotr Szymanek

Conscious Cogn 2021 Jun 9;93:103163. Epub 2021 Jun 9.

Faculty of Philosophy, Jagiellonian University, Gołębia 24, 31-007 Kraków, Poland. Electronic address:

The commonsense view is that a lucid dream starts when the dreamer realizes that they are currently dreaming. The notion of realization, however, has been accepted at face value, with little consideration of whether the dreamer realizes that they are dreaming in the sense of actual reasoning, or if it is a mere epiphenomenon of lucid dream initiation. This article offers a solution to this problem by, first, arguing that the transition to lucidity can occur as a result of successful reasoning, and second, building a model of this reasoning in terms of probabilistic reasoning.

Prog Biophys Mol Biol 2021 Jun 9. Epub 2021 Jun 9.

Sabancı University, Faculty of Engineering and Natural Sciences, 34956 Tuzla, İstanbul, Turkey. Electronic address:

DNA undergoes spontaneous point mutations, which are believed to be central to the evolution of the organisms and which are thought to occur by tautomerization of the canonical Guanine-Cytosine (G-C) base pair into non-canonical G*-C* base pair via the double proton tunneling. In the present work, we close a gap in the literature by computing the time delay during the proton tunneling. Our results, based on the well-known dwell time and our model of the entropic time, range from femtoseconds to picoseconds, and completely agree with the time scales of the structural changes in molecules (mutation processes not the complete replication processes).

How organizational culture influences holistic review: a qualitative multiple case study.

Adv Health Sci Educ Theory Pract 2021 Jun 12. Epub 2021 Jun 12.

Edson College of Nursing and Health Innovation, Arizona State University, Downtown Phoenix Campus, Phoenix, AZ, USA.

Studies primarily involving single health professions programs suggest that holistic review in admissions can increase underrepresented minority (URM) representation among admitted students. However, data showing little improvement in the overall proportion of URMs in many health professions, despite widespread use of holistic review, suggest that relatively few programs using holistic review admit substantial proportions of underrepresented minorities. Therefore, more research is needed to understand factors that facilitate holistic review practices that successfully promote diverse student enrollment. Read More

FGFBP1-mediated crosstalk between fibroblasts and pancreatic cancer cells via FGF22/FGFR2 promotes invasion and metastasis of pancreatic cancer.

Acta Biochim Biophys Sin (Shanghai) 2021 Jun 12. Epub 2021 Jun 12.

Department of Pancreatic Surgery, Fudan University Shanghai Cancer Center, Shanghai 200031, China.

Fibroblast growth factor-binding protein 1 (FGFBP1) promotes fibroblast growth factor (FGF) activity by releasing FGFs from extracellular matrix storage. We previously reported that the tumor suppressor F-box and WD repeat domain-containing 7 suppresses FGFBP1 by reducing expression of c-Myc, which inhibits the proliferation and migration of pancreatic cancer cells. However, the potential mechanism by which FGFBP1 facilitates pancreatic ductal adenocarcinoma (PDAC) remains unexplored. Read More

Regulation of gametangia and gametangiophore initiation in the liverwort Marchantia polymorpha.

Plant Reprod 2021 Jun 11. Epub 2021 Jun 11.

Graduate School of Biostudies, Kyoto University, Kyoto, 606-8501, Japan.

Key Message: The liverwort Marchantia polymorpha regulates gametangia and gametangiophore development by using evolutionarily conserved regulatory modules that are shared with angiosperm mechanisms regulating flowering and germ cell differentiation. Bryophytes, the earliest diverged lineage of land plants comprised of liverworts, mosses, and hornworts, produce gametes in gametangia, reproductive organs evolutionarily conserved but lost in extant angiosperms. Initiation of gametangium development is dependent on environmental factors such as light, although the underlying mechanisms remain elusive. Read More
