Detection of bearing faults is a challenging task since the impulsive pattern often fades into noise. Moreover, tracking health conditions rotating machinery generally requires characteristic frequencies components interest, which can be cumbersome constraint for large industrial applications because extensive number machine components. One recent method proposed in literature addresses these d...

While a digital arteriovenous anastomosis (Hoyer-Grosser's organ, Masson's glomus) is well-known structure, photographic evidence of communication between arterial and venous lumens might not be demonstrated in routine histological or immunohistochemical analysis. Abundant clusters so-called glomera were found semi-serial sections the distal aspect 14 fingers obtained from 7 donated elderly cad...

Antihemophilic factor (AHF, factor VIII) is a macromolecule that can be dissociated into two subcomponents. One, of high molecular weight (MW), forms precipitates with heterologous antiserum against AHF and supports ristocetin-induced aggregation of platelets. The other, of lower MW, has procoagulant activity. The plasma of patients with classic hemophilia contains a form of AHF with properties...
