Intrafamilial medically assisted reproduction [PDF]

open access: yes, 2011
For different motives, couples in need of third party assisted reproduction sometimes prefer the help of a family member over an unrelated collaborator. Quantitative (frequency) and qualitative (experience) data about this practice are lacking or scarce.

Informativeness of phosphatidylethanol homologues as markers of alcohol consumption

open access: yesActa Biomedica Scientifica
Background. Prenatal alcohol exposure is associated with adverse health effects on the developing fetus. Phosphatidylethanol (PEth) are specific direct biomarkers of alcohol that can be detected in human blood.The aim.

In rats with estradiol valerate-induced polycystic ovary syndrome, the acute blockade of ovarian β-adrenoreceptors improve ovulation

open access: yesReproductive Biology and Endocrinology, 2019
Background Polycystic ovary syndrome is characterized by hyperactivity of the ovarian sympathetic nervous system, increases in the content and release of norepinephrine, as well as decreases in the number of β-adrenoreceptors.

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Extracellular vesicles and its advances in female reproduction [PDF]

open access: yes, 2018
Intercellular communication is an essential mechanism for development and maintenance of multicellular organisms. Extracellular vesicles (EVs) were recently described as new players in the intercellular communication.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

The net reproduction rate and the type-reproduction number in multiregional demography [PDF]

open access: yes
In order to study effects of migration on demographic changes of multiregional populations, multiregional population modelling is a useful traditional tool.

Endocrine Disruptors in Domestic Animal Reproduction: A Clinical Issue? [PDF]

open access: yes, 2015
The objective of this review was to discuss whether endocrine disruption is a clinical concern in domestic animal reproduction. To that end, we firstly summarize the phenomenon of endocrine disruption, giving examples of the agents of concern and their ...
