THE BACTERIAL FIMBRIAL TIP ACTS AS A MECHANICAL FORCE SENSOR.

The bacterial fimbrial tip acts as a mechanical force sensor.

There is increasing evidence that the catch bond mechanism, where binding becomes stronger under tensile force, is a common property among non-covalent interactions between biological molecules that are exposed to mechanical force in vivo.Here, by using the multi-protein tip complex of the mannose-binding type 1 fimbriae of Escherichia coli, we sho

Quality management of electric energy and compensation of reactive power in the electric power system by means of stimulating tariffs

The article noted that feed-in tariffs are effective enough to attract consumers to participate in the process of improving power Respirators quality and reactive power compensation.It is shown that the application of premiums and discounts must not modify the revenues of the budget of ESO.Otherwise there is a contradiction to the principles of sta

A progressive compression model of thoracic spinal cord injury in mice: function assessment and pathological changes in spinal cord

Non-traumatic injury accounts for approximately half of clinical spinal cord injury, including chronic spinal cord compression.However, previous rodent spinal cord compression models are mainly designed for rats, few are available for mice.Our aim is to develop a thoracic progressive compression mice model of spinal cord injury.In this study, adult

Human phosphatidylethanolamine-binding protein 4 promoted the radioresistance of human rectal cancer by activating Akt in an ROS-dependent way.

Human phosphatidylethanolamine-binding protein 4(hPEBP4) is a novel anti-apoptosis molecule associated with the resistance of tumors to apoptotic agents.Here we sought to investigate the role of hPEBP4 in the radioresistance of rectal cancer.Immunohistochemistry analysis showed hPEBP4 was expressed in 27/33 of rectal cancer specimens, MARSHMALLOWS
