Rodents as a reservoir of infection caused by multiple zoonotic species/genotypes of C. parvum, C. hominis, C. suis, C. scrofarum, and the first evidence of C. muskrat genotypes I and II of rodents in Europe.

Cryptosporidium spp. is an important causative agent of intestinal parasitoses-induced diarrhoea in humans and animals worldwide. Rodents (small mammals), the main reservoir of infections, are globally expanded and overpopulated, which increases the risk of transfer of human and zoonotic pathogens from the genus Cryptosporidium.

Coverage-dependent morphology of PEGylated lysozyme layers adsorbed on silica.

Neutron reflection was used to characterize the adsorbed layer structure for lysozyme conjugated at the N-terminus with a single perdeuterated methoxy poly(ethylene glycol) (PEG) chain at the silica/water interface. Adsorbed layers were produced with two different surface concentrations corresponding to opposite sides of a pronounced transition in the adsorption isotherm for mono-PEGylated lysozyme. The transition was previously ascribed, on the basis of less direct characterization by normal force measurements, to a change in the distribution of the conjugated PEG chain segments in the interfacial region in response to lateral repulsions (S.

Incidence and management of subdural hematoma/hygroma with variable- and fixed-pressure differential valves: a randomized, controlled study of programmable compared with conventional valves.

Shunt systems with differential pressure valves are prone to the complications of overdrainage. A programmable valve permits adjustment of the opening pressure of the valve. In this paper the authors report the incidence of subdural fluid collections in a randomized trial of programmable compared with conventional valves, and they describe methodologies used in management of this complication.
