Summary : Skin melanoma is one of the deadliest among human skin tumors, and surgery remains first main method in its combined treatment. Despite seemingly radical nature surgical interventions patients with primary melanoma, frequency locoregional recurrence metastasis high. The question impact treatment on evolution microenvironment unclear. Aim to investigate dynamics polarization tumor-asso...

OBJECTIVE To determine whether there is significant atrial or atrial appendage enlargement or functional remodelling as a result of one to two months of sustained atrial fibrillation, a duration similar to that experienced by patients undergoing warfarin anticoagulation before elective cardioversion. METHODS To test the hypothesis that left atrial and left atrial appendage enlargement develop...

At present, the robot embedded system has some common problems as poor closure and dynamic evolution. Aiming at the situation, the paper focused on the improvement of robot embedded system, and set up architecture of robot system whose control center is Appendage SoftMan based on the syncretic mechanism of robot and SoftMan. The paper mainly paid attention to the research on Appendage SoftMan: ...

A fault-tolerant gait planning of a quadruped robot is presented. The considered robot has static walking and suffers from a locked joint failure. Especially, the quadruped robot is equipped with the moving appendage onto the body. By controlling the moving appendage, the robot can adjust the effective position of the center of gravity. Incorporating the adjustment of the moving appendage along...

Newly formed centrioles in cycling cells undergo a maturation process that is almost two cell cycles long before they become competent to function as microtubule-organizing centers and basal bodies. As a result, each cell contains three generations of centrioles, only one of which is able to form cilia. It is not known how this long and complex process is regulated. We show that controlled Plk1...

Calcified marine organisms typically experience increased oxidative stress and changes in mineralization in response to ocean acidification and warming conditions. These effects could hinder the potency of animal weapons, such as the mantis shrimp's raptorial appendage. The mechanical properties of this calcified weapon enable extremely powerful punches to be delivered to prey and aggressors. W...

Skin exhibits remarkable regional specificity. However, the epigenetic mechanism underlying this process remains elusive. In study, we used avian scalp skin as a model and leveraged finding that tandem 195-bp duplication in intron of HoxC10 causes chicken Crest phenotype. Crested chickens (e.g., Polish chickens) exhibit elongated feathers region comb is minute. Along anterior-posterior midline ...

Ablation from the right atrial appendage usually requires its isolation with the applications of...

Whereas the left atrial appendage plays a rather minor role under physiological circumstances, it gains an importance in patients with atrial fibrillation. Compelling evidence has revealed that the left atrial appendage is implicated as the source of thrombus in the vast majority of strokes in atrial fibrillation. Oral anticoagulation remains the standard of care for stroke prevention in atrial...
