We describe a high optical performance 3.4 μm pixel pitch global shutter CMOS image sensor with multiple accumulation shutter technology and a large tapered light guide structure. The pixel achieves 1.8 etemporal noise and full well capacity of 16,200 ewith charge domain memory in 120 fps operation. The sensitivity and parasitic light sensitivity are 28,000 e-/lx·s and -89 dB, respectively. Mor...

The sensitivity of 127 strains of miscellaneous Gram-negative bacilli to various cephalosporins was determined by three methods. Disc tests with cephaloridine (CLOR), cephalothin (CTIN) and cephalexin (CLEX) made most strains of beta-lactamase-producing Escherichia coli appear sensitive. Eight cephalosporins were tested by the agar break-point method using concentrations of 16 and 4 mg/l for al...

The Echinococcus Western Blot IgG (LDBIO Diagnostics, Lyon, France), using a whole larval antigen from Echinococcus multilocularis, was evaluated for serodiagnosis and differentiation between two human parasitic infections of worldwide importance: cystic echinococcosis, due to Echinococcus granulosus, and alveolar echinococcosis, due to E. multilocularis. Fifty and 61 serum samples from patient...

Immunodominant antigens of an approximate molecular mass of 27 kDa (FG 27) were obtained from an excretory-secretory product of adult Fasciola gigantica by a simple continuous-elution method. A dot-ELISA using the FG 27 antigen was developed for the detection of specific antibodies from patients infected with F. gigantica. Control sera were obtained from patients with other parasitic infections...

Guidelines are suggested to implement the introduction of beneficial insect-parasitic nematodes into the United States from abroad. These suggestions result from experiences and research with these and other biological control agents and from the current need for procedures to import nematodes. Subjects considered are need to import, foreign exploration, taxonomy, shipment, quarantine facilitie...
