A total of 252 strains of group B streptococci were serotyped and examined for their ability to ferment lactose (lac+), to hydrolyze salicin (sal+), and to produce hyaluronidase (hy+). Of these strains, 67 had been isolated from bacteremia and meningitis in infants less than 2 months old. Eighty-one strains were isolated from bacteremia and meningitis in adults, and 104 strains were from variou...

When two prion strains infect a single host, one strain can interfere with the ability of the other to cause disease but it is not known whether prion replication of the second strain is also diminished. To further investigate strain interference, we infected hamsters in the sciatic nerve with the long-incubation-period transmissible mink encephalopathy (TME) agent DY TME prior to superinfectio...

BACKGROUND AND AIMS Hyperforin (HY) is used to treat depression and skin irritation and has been shown a number of pharmacological activities. The literature does no cite data on changes that may occur in the body after HY intake (ethylene diammonium salt - EDS) in long-term administration. From this point of view, the present work is a key to determining the pharmacotoxicological profile of th...

This investigation examined the distinct and interactive effects of initial hydration state, exercise-induced dehydration, and water rehydration in a hot environment. On four occasions, 10 men performed a 90-min heat stress test (treadmill walking at 5.6 km/h, 5% grade, 33 degrees C, 56% relative humidity). These heat stress tests differed in pretest hydration [2 euhydrated (EU) and 2 hypohydra...

The title compound, C25H24N4O2, adopts a cisoid configuration and has twofold orientational disorder of the 2-hy-droxy-ethyl group. The mol-ecule is twisted from planarity so that the dihedral angle between the terminating indol-2-yl-idene and the furan-2-yl-idene moiety mean planes is 12.75 (7)°. Conformational disorder occurs at the indol-2-yl-idene N atom, which results in two orientations f...

In the reaction of 8-hy-droxy-quinoline, 2-methyl-8-hy-droxy-quinoline and stannic chloride, the 2-methyl-8-hy-droxy-quinoline is protonated, yielding the disolvated title salt, (C(10)H(10)NO)[SnCl(4)(C(9)H(6)NO)]·2CH(3)OH. The Sn(IV) atom in the anion is N,O-chelated by the hy-droxy-quinolinate in a cis-SnNOCl(4) octa-hedral geometry. In the crystal, the cation, anion and solvent mol-ecules ar...

The Chinese Ocean Color and Temperature Scanner (COCTS) on board HY-1 series satellites has two thermal infrared channels with the spectrum range of 10.30-11.40 μm 11.40-12.50 for sea surface temperature (SST) observations. To reprocess Haiyang-1B (HY-1B) COCTS SST, Bayesian cloud detection optimal estimation (OE) SST retrieval were applied to data in this study. algorithm that been deve...

The title compound, C(35)H(35)NO(2)·CH(4)O, was obtained by the reaction of rac-2-amino-2-hy-droxy-1,1-binaphthyl and 3,5-di-tert-butyl-2-hy-droxy-benzaldehyde in absolute methanol. In the Schiff base mol-ecule, the two naphthyl bicycles are twisted by 71.15 (5)°. One hy-droxy group is involved in intra-molecular O-H⋯N hydrogen bond, while the methanol solvent mol-ecule is linked to another hy-...
