BACKGROUND In Japan, there is no decision-making guide regarding long-term tube feeding that specifically targets individuals making decisions on behalf of cognitively impaired older persons (substitute decision makers). The objective of this study was to describe the development and evaluation of such a decision aid. METHODS In this before-and-after study, participants comprised substitute d...

conclusions the results of this meta-analysis show that colloid fluids can increase the successful resuscitation rate compared to crystalloid fluids especially in traumatic and hypovolemic patients.some of the colloids like albumin and dextran have a positive effect on reducing the mortality rate but others like hetastarch (hes) increase the mortality rate compared to normal saline (ns). result...

BACKGROUND Dental stem cells in combination with implant materials may become an alternative to autologous bone transplants. For tissue engineering different types of soft and rigid implant materials are available, but little is known about the viability and the osteogenic differentiation of dental stem cells on these different types of materials. According to previous studies we proposed that ...

The optimum management for recurrent glenohumeral instability with significant humeral head defects remains controversial. The purpose of this study was to compare outcomes and recurrence rates between patients who underwent osteochondral substitute grafting and patients who underwent remplissage to treat recurrent shoulder instability from an engaging Hill-Sachs defect with a Bankart lesion. T...

The novel dinuclear Zn(ii) complex (1) containing a beta-CD dimer could accelerate BNPP (a DNA substitute) hydrolysis more efficiently than catalyze HPNP (a RNA substitute) transesterification with different mechanisms involved; the beta-CDs played remarkably different roles.

PURPOSE Pluripotent cells residing in the periosteum, a bi-layered membrane enveloping all bones, exhibit a remarkable regenerative capacity to fill in critical sized defects of the ovine femur within two weeks of treatment. Harnessing the regenerative power of the periosteum appears to be limited only by the amount of healthy periosteum available. Here we use a substitute periosteum, a deliver...

We studied a new injectable biomaterial for bone and dental surgery consisting of a hydrophilic polymer as matrix and bioactive calcium phosphate (CaP) ceramics as fillers. This material is composed of complex fluids whose flow is determined by the laws of rheology. We investigated the macromolecular effects on this composite in a tube. The stability of the polymer and the mixture is essential ...
