In her thesis, obstetrician Berith Karlsson Tingåker has examined the source of pain during childbirth and how uterine sensitivity to pain changes during pregnancy. Her results show that labour pains mainly derive from the cervix, where the number of pain-related nerve fibres and receptors is much greater than in the uterus at full-term pregnancy.
Her thesis also shows that uterine pain sensitivity differs markedly between pregnant and non-pregnant women. In the latter, the entire uterus is pain-sensitive, while in the former, the pain-sensitive nerve fibres disappear almost completely from the main body of the uterus, but remain in the cervix.
Spinal anaesthesia is currently the most effective way of providing pain relief. However, it is a resource-demanding method and has other drawbacks that limit its practicability.
“The results create new opportunities for developing simpler and more effective methods of pain relief, with the focus on the cervix,” says Berith Karlsson Tingåker. “Women in Sweden and around the world, many of whom have no access to pain relief, are literally crying out for them.”

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
