We have recently demonstrated that heterologous transplantation of horse amniotic membrane-derived mesenchymal cells (AMCs) can be useful for cell therapy applications in tendon diseases, and hypothesized these may promote repair via paracrine-acting molecules targeting inflammatory processes. To test this hypothesis, here we examined the immunomodulatory characteristics AMCs their conditioned medium (AMC-CM) vitro, studied potential therapeutic effect AMC-CM thirteen different spontaneous...

Cats are susceptible to infection with severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2). Whilst a number of studies have been performed worldwide on owned cats, limited data available stray, colony or shelter cats. We investigated SARS-CoV-2 in stray cat population before and during human outbreaks cities the Lombardy region northern Italy, high endemic for SARS-CoV-2, using serological molecular methods. A cohort different samples were collected from 241 including frozen...

An asynchronous version of a binary pixel readout circuit has been implemented in an array with 16 columns at 500 mu m pitch and 63 rows 75 pitch. This chip bonded solder bumps to silicon detector matching elements. Event information can be strobed into local memory by trigger signal subsequently read out. Without strobe the this is continuously cleared. The complete hybrid successfully tested ionizing particles from radioactive source. Three such devices have used CERN heavy ion experiment...
