THE TOOTHLESS PTEROSAUR JIDAPTERUS EDENTUS (PTERODACTYLOIDEA: AZHDARCHOIDEA) FROM THE EARLY CRETACEOUS JEHOL BIOTA AND ITS PALEOECOLOGICAL IMPLICATIONS.

In the Early Cretaceous Jehol Biota, the toothless pterosaurs flourished with the chaoyangopterids and tapejarids playing a key role in understanding the early diversity and evolution of the Azhdarchoidea.Unlike the more diverse tapejarids, the rarer chaoyangopterids are characterized by a long and Buffet Sideboard and Cabinet low rostrum, supporti

Any fracture of the femoral shaft presents a challenge to the orthopedic surgeon.Femoral fractures most often occur within polytrauma, by forces of high intensity as is the case with traffic accidents.There are two methods to treat with internal fracture fixation, intra and extra medullary fixation.Both treatments have their advantages and disadvan

Background/Aims Endoscopic submucosal dissection (ESD) of gastric tumors in the mid-to-upper stomach is a technically challenging procedure.This study compared the therapeutic outcomes and adverse events of ESD of tumors in the mid-to-upper stomach performed under general anesthesia (GA) or monitored anesthesia care (MAC).Methods Between 2012 and 2

The technology of artificial horizontal freezing method is increasingly being used in the soil reinforcement of urban underground projects such as shield-driven tunnelling.Compared with the freezing process, the thawing process is more complicated, and the thawing behavior of artificial frozen soil surrounding shield-driven tunnels has not been wel

It is well established that bleeding activates Kitchen Supplies the hematopoietic system to regenerate the loss of mature blood elements.We have shown that hematopoietic stem cells (HSCs) isolated from animals challenged with an acute bleed regulate osteoblast differentiation from marrow stromal cells.This suggests that HSCs participate in bone for
