Light‐Driven Quadrupedal Walking Biohybrid Robot With Antagonistic Muscle‐Rings and Inclined Joints
Advanced Robotics Research, EarlyView.This work presents a light‐driven quadrupedal walking biohybrid robot powered by antagonistic muscle‐rings that achieve alternating walking gait. Optical training improved reproducibility of cultured muscle tissues, while caffeine treatment enhanced contractile force.

Advanced Science, EarlyView.Our study reveals the protective role of GPR124 in maintaining BBB integrity and promoting neurological recovery following TBI. It makes a significant contribution by uncovering a novel molecular interaction between GPR124 and FGFBP1 and linking this to activation of the Wnt/β‐catenin signaling pathway in vascular repair mechanisms.

Relaxin and the Human Fetal Membranes
Reproductive Sciences, 2007The human fetal membranes are complex tissues that perform many important functions during gestation. The extracellular matrix provides their strength to withstand the forces directed from the fetus and myometrium. Relaxin is a collagenolytic hormone that causes increased production of the matrix metalloproteinases.

Premature Rupture of Fetal Membranes
Postgraduate Medicine, 1967Premature rupture of fetal membranes increases maternal morbidity and perinatal mortality when labor does not ensue promptly. Two schools of management of this problem have developed: the activists, who favor induction of labor if it does not occur spontaneously within 24 hours, and the conservatives, who prefer close clinical observation with no ...

Premature Rupture of the Fetal Membranes
New England Journal of Medicine, 1998The membranes surrounding the amniotic cavity are composed of the amnion and the chorion, which are closely adherent layers consisting of several cell types, including epithelial cells, mesenchymal cells, and trophoblast cells, embedded in a collagenous matrix.

The validity of the concepts of exchange and net flow and of the method used to measure them was proved by utilizing a standard artificial membrane. The exchange rates across the amniochorion of D- and L-isomers of various amino acids have been measured. They do not differ.

Acta Obstetricia et Gynecologica Scandinavica, 1983
Abstract. Samples from different parts of the fetal membranes were examined by both light and transmission electron microscopy. Samples were obtained during elective ce‐sarean section after full‐term normal pregnancy. The results indicated that the different layers of the membranes had undergone ukrastructural changes varying according to the site ...

Retention of the fetal membranes in cattle
Veterinary Record, 1976An investigation of the possible significance of 'stress' as a factor in the retention of bovine fetal membranes has been carried out, together with the investigation as to the possible variation of progesterone levels at parturition, as a cause of retention.

The purpose of this study was to determine the biomechanical characteristics of human fetal membranes (FM) throughout gestation. Biomechanical properties were determined for 115 FM of 23-41 weeks gestation using our previously described methodology. The areas of membrane immediately adjacent to the strongest and weakest tested spots were sampled for ...
