The EMBO Journal, 2005 Stem cells are unique in their capacity to self-renew and generate differentiated progeny to maintain tissues throughout life. A common molecular program for stem cells has remained elusive. We discuss what the molecular logic of stemness may be. We suggest that it may not be coupled to distinct cellular properties such as self-renewal or multipotency,

Plastic and Reconstructive Surgery, 2010 Stem cells are self-renewing cells capable of differentiating into multiple cell lines and are classified according to their origin and their ability to differentiate. Enormous potential exists in use of stem cells for regenerative medicine. To produce effective stem cell-based treatments for a range of diseases, an improved understanding of stem cell ...

Effects of material properties of femoral hip components on bone remodeling [PDF]
, 1992 Bone loss around femoral hip stems is one of the problems threatening the long-term fixation of uncemented stems. Many believe that this phenomenon is caused by reduced stresses in the bone (stress shielding).

Analysis of Thermodynamic Modelling for Gamma Type Double Piston Cylinder Engine [PDF]
E3S Web of Conferences, 2021 The exhaust of an automotive engine is one of the main causes of air pollution. These days, many researchers are investigating the waste heat recovery of automotive engines. A two-cylinder gamma-type Stirling engine is chosen for this purpose.

Science, 2007 Two converging events took place on 9 August that ought to have the scientific community scratching its collective head. One of these is an anniversary: On that date in 2001, President George W. Bush signed an Executive Order banning any use of federal funds to support research on stem cells (save, of course, for those 78 preexisting cell lines, only ...

Temperature and inoculation method influence disease phenotypes and mortality of Eucalyptus marginata clonal lines inoculated with Phytophthora cinnamomi [PDF]
, 2002 Survival of 1-year-old plants of three clonal lines of Eucalyptus marginata (jarrah), two ranked as resistant (RR1 and RR2) and one as susceptible (SS1) to Phytophthora cinnamomi, was assessed after pathogen inoculation with either mycelial mats ...

Research interdisciplinarity: STEM versus non-STEM [PDF]
Scientometrics, 2020 Research collaboration among interdisciplinary teams has become a common trend in recent days. However, there is a lack of evidence in literature regarding which disciplines play dominant roles in interdisciplinary research settings. It is also unclear whether the dominant role of disciplines vary between STEM (Science, Technology, Engineering, and ...

Bone & Joint Open, 2021 Aims: Varus-valgus constrained (VVC) devices are typically used in revision settings, often with stems to mitigate the risk of aseptic loosening. However, in at least one system, the VVC insert is compatible with the primary posterior-stabilized (PS ...
