Does joint cartilage require energy?

Does joint cartilage require energy? SIR, Geborek et al showed that induced increase of synovial fluid pressure decreases synovial blood flow,' which, as expected,2 decreases synovial fluid oxygen tension.3 In five minutes synovial fluid pressure raised by flexion decreased synovial fluid oxygen tension in 3/10 cases of knee trauma; these three synovial fluids contained few red cells, potential...

Does radiofrequency ablation (RFA) epiphysiodesis affect adjacent joint cartilage?

PURPOSE To test the hypothesis that epiphysiodesis made with radiofrequency ablation (RFA) is a safe procedure that disrupts the growth plate without damaging the adjacent joint articular cartilage. METHODS RFA epiphysiodesis was done during 8 min in vivo in 40 growing pig tibia physis. In addition, three tibiae were ablated for 16 min and three more for 24 min. As a burned cartilage referenc...

Does intelligence require a body?

Our brain controls our body—every movement we make is guided by neuronal activity. But how about vice versa? Does the body influence our brain; does it have an impact on how we think? This question might seem odd. We usually stick to a simple ‘sense– think–act’ paradigm: we hear the phone ring (sense), we recognize that we should answer it (think) and grab the receiver (act). This is a one-way ...

Does Privacy Require True Randomness?

Most cryptographic primitives require randomness (for example, to generate their secret keys). Usually, one assumes that perfect randomness is available, but, conceivably, such primitives might be built under weaker, more realistic assumptions. This is known to be true for many authentication applications, when entropy alone is typically sufficient. In contrast, all known techniques for achievi...
