A mysterious appearance at zone 1

The mysterious appearance of objects

Moving from some reflections on the empirical practice of measurement and on the nature of visual perception, we present a constructivist approach to objects. At the basis of such approach there is the idea that all we may know about what is out there is always mediated by some sort of apparatus, being it a measurement instrument or our perceptual system. Given this perspective, some questions ...

Hyaluronan Synthase 1: A Mysterious Enzyme with Unexpected Functions

Hyaluronan synthase 1 (HAS1) is one of three isoenzymes responsible for cellular hyaluronan synthesis. Interest in HAS1 has been limited because its role in hyaluronan production seems to be insignificant compared to the two other isoenzymes, HAS2 and HAS3, which have higher enzymatic activity. Furthermore, in most cell types studied so far, the expression of its gene is low and the enzyme requ...

A mysterious ‘homesickness’

An 82-year-old female patient presented with fever and chills of two weeks’ duration. Because of pyuria on dipstick, sulfamethoxazole and trimethoprim had been empirically initiated. On admission, temperature was 38.5◦C. Blood tests showed increased C-reactive protein and creatinine serum levels (Figure A). White blood cell count was normal. Urinalysis confirmed leucocyturia (350/hpf) but urine...
