DOPAC as a modulator of α-Synuclein and E46K interactions with membrane: Insights into binding dynamics.

α-Synuclein (Syn) is an intrinsically disordered protein, abundant in presynaptic neurons. It is a constituent of the Lewis Body inclusions as amyloid fibrils, in Parkinson's disease patients. It populates an ensemble of conformations and floats between the free random coil and the membrane-bound α-helical species.

The serine-rich repeat glycoprotein Srr2 mediates Streptococcus agalactiae interaction with host fibronectin.

Background: Group B Streptococcus (GBS) is a commensal of healthy adults and an important pathogen in newborns, the elderly and immunocompromised individuals. GBS displays several virulence factors that promote colonisation and host infection, including the ST-17 strain-specific adhesin Srr2, previously characterised for its binding to fibrinogen. Another common target for bacterial adhesins and for host colonization is fibronectin, a multi-domain glycoprotein found ubiquitously in body fluids, in the extracellular matrix and on the surface of cells.

From haemadin to haemanorm: Synthesis and characterization of full-length haemadin from the leech Haemadipsa sylvestris and of a novel bivalent, highly potent thrombin inhibitor (haemanorm).

Hirudin from Hirudo medicinalis is a bivalent α-Thrombin (αT) inhibitor, targeting the enzyme active site and exosite-I, and is currently used in anticoagulant therapy along with its simplified analogue hirulog. Haemadin, a small protein (57 amino acids) isolated from the land-living leech Haemadipsa sylvestris, selectively inhibits αT with a potency identical to that of recombinant hirudin (K  = 0.2 pM), with which it shares a common disulfide topology and overall fold.

[Leukemia mortality and incidence of infantile leukemia near the Vatican Radio Station of Rome].

Some recent epidemiological studies suggest an association between lymphatic and haematopoietic cancers and residential exposure to high frequency electromagnetic fields (100 kHz-300 GHz) generated by radio and television transmitters. Vatican Radio, a very powerful radio station transmitting all over the world (up to 600 kW) is located in Santa Maria di Galeria, in the northern suburbs of the city of Rome. Electric field measurements in the proximity of the radio station ranged between 1.
