Cyclic Mechanical Loading of Cardiomyocytes via Pressure‐Driven Non‐Planar Membrane Deformation in a Bioreactor System

Advanced Science, EarlyView.
In this research article, Mansoor and coworkers present a novel device that applies controlled mechanical stimuli to cardiomyocytes using pressure‐driven membrane deformation. By exposing cells to physiologically and pathologically relevant loading conditions, the platform reproduces distinct structural, functional and molecular responses associated ...

Sustainable Fabrication of Tailored Bone Substitutes: From High‐Throughput Scaffold Manufacturing, Scaled‐Up HMSC Expansion to Dynamic Cultivation in a Perfusion Bioreactor

Advanced Science, EarlyView.
ABSTRACT The demand for off‐the‐shelf biocompatible bone substitutes has driven the development of numerous independent in vitro technologies to generate products resembling physiological tissues. Due to technical challenges and overly simplified cultivation approaches/niches, the end‐products are often uniformly shaped and inferior to native bone ...

Lilrb4a Suppression Reprograms Microglia to Mitigate APOE4‐Associated Amyloid Plaques and Cerebral Amyloid Angiopathy in Association With a PPAR‐Linked Pro‐Clearance State

Advanced Science, EarlyView.
Targeting Lilrb4a in Apolipoprotein E4 (APOE4)‐associated Alzheimer's disease (AD) reprograms microglia toward a beneficial, phagocytic state. Genetic deletion or antisense inhibition of Lilrb4a suppresses p‐SHP2/NF‐κB/STAT1 signaling, restores PPAR‐linked lipid and energy metabolism, and reduces amyloid plaque burden and cerebral amyloid angiopathy ...

Molecular Editing Reveals a Bilobalide Chemotype that Attenuates Prolyl Endopeptidase (PREP)‐Linked Neuroinflammation

Advanced Science, EarlyView.
Molecular editing of bilobalide uncovers BB56, a PREP‐engaging chemotype with enhanced anti‐inflammatory activity in microglia. Integrated CETSA‐MS, SAR, and pathway analyses link BB56 to attenuation of p38 MAPK/NF‐κB and NLRP3‐associated inflammatory signaling, highlighting bilobalide editing as a strategy for developing neuroinflammation‐modulating ...

Quality control of embryo development

Molecular Aspects of Medicine, 2013
Although in recent years we have seen an undeniable improvement in the field of reproductive biology and medicine, the efficiency of in vitro fertilization (IVF) procedures remains relatively low, ranging from 4% to 40% depending on the patient's age. It is believed that this is in a large part caused by inaccurate assessment of embryo quality prior to

Ovarian stimulation and embryo quality

Reproductive BioMedicine Online, 2009
To study the effects of different ovarian stimulation approaches on oocyte and embryo quality, it is imperative to assess embryo quality with a reliable and objective method. Embryos rated as high quality by standardized morphological assessment are associated with higher implantation and pregnancy rates.

Quantification of embryo quality by respirometry

Theriogenology, 2007
It is generally accepted that assessment of embryo metabolism, in particular oxygen consumption, may improve embryo selection by identifying the embryos with higher developmental competence. Several methods have been employed to measure embryonic oxygen consumption, but most of them were detrimental to subsequent embryo development.

Contribution of the oocyte to embryo quality

Theriogenology, 2006
The ability of a bovine embryo to develop to the blastocyst stage, to implant and to generate a healthy offspring is not a simple process. To clarify the importance of the contribution of the oocyte to the embryo quality, it is important to define more precisely the different types of competence expressed by oocytes.

Production and Quality of Bovine Oocytes and Embryos

Veterinary Research Communications, 2004
Many factors influence the efficiency of the in vitro embryo production technology in cattle but the most important are the physiological conditions of the donor and the culture protocols for oocyte maturation and fertilization and for embryo culture from zygote to blastocyst.

Embryo Quality Assessment

Journal SOGC, 1995
Abstract Multiple pregnancy is a common complication of in vitro fertilization (IVF). Embryo quality assessment may allow us to reduce significantly the risk of multiple births by transferring two instead of three pre-embryos per cycle of IVF. So far, the assessment of embryo quality has been mainly morphological, which correlates with the chances of ...
