Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Clinical aspects of embryo implantation: from the perspective of tissue perfusion. [PDF]

open access: yes, 2006
Hypothesis: Pelvic perfusion is the pivotal factor for the outcome of in vitro fertilisation (IVF) treatment once clinical and embryological variables are controlled for their effect.;Demonstration of Hypothesis: In a series of three studies, the ...

PADI2 exacerbates Mycoplasma ovipneumoniae-induced lung injury in sheep by suppressing M2 macrophage polarization

open access: yesVeterinary Research
Macrophages are considered the first line of defence against Mycoplasma pneumoniae infection in sheep, and their polarization significantly affects lung tissue damage and remodelling.

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.

HLA-G MOLECULES: FROM EMBRYO IMPLANTATION TO OOCYTE MATURATION [PDF]

open access: yes, 2009
Background Assisted reproduction technique (ART) pregnancy rates have not changed in recent years and an increased risk of twins, triplets or higher order pregnancies leads to a perinatal mortality and morbidity.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Optimizing embryo culture conditions and spent culture media analysis as predictors of embryo quality and pregnancy [PDF]

open access: yes, 2021
Philosophiae Doctor - PhDThe aim of this thesis is first, to evaluate various culture conditions to improve embryo development, and secondly, to analyze spent culture media for any biomarkers that may be predictive of embryo health.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

THE IDENTIFICATION OF CHROMOSOMAL POLYMORPHISM IN ONE BREED OF IRAQI SHEEP

open access: yesThe Iraqi Journal of Veterinary Medicine, 1989
A chromosomal analysis of three breeds of Iraqi sheep (Karadi Arabi and Awassi) has been performed on peripheral lymphocytes. The modal chromosome number of all the three breeds was found to be (2n=54XX/54XY) for femal and male respectively.

Detrimental effects of lipopolysaccharides on maturation of bovine oocytes [PDF]

open access: yesAsian-Australasian Journal of Animal Sciences, 2019
Objective Gram-negative bacteria lipopolysaccharide (LPS) has been reported to be associated with uterine impairment, embryonic resorption, ovarian dysfunction, and follicle retardation.
