In the title compound, C8H10O3, the hy-droxy-methyl group is twisted by 74.51 (13)° from the plane of the benzene ring to which it is connected. By contrast, the benzene and meth-oxy groups are almost coplanar, making a dihedral angle of 4.0 (2)°. In the crystal, O-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.

Current models of T cell memory implicate a critical role for IL-7 in the effector-to-memory transition, raising the possibility that IL-7 therapy might enhance vaccine responses. IL-7 has not been studied, to our knowledge, before now for adjuvant activity. We administered recombinant human IL-7 (rhIL-7) to mice during immunization against the male antigen HY and compared these results with th...

This study was made to separate genetic from postnatal maternal influences on yawning in two strains of Sprague-Dawley rats selected for high- (HY) and low-yawning frequency (LY). Foster mothers of the two strains reared litters of pups in the four possible combinations and yawning was recorded in a novel environment when the adult offspring were 75-day-old. Yawning frequency of males and femal...

In the title compound, C(11)H(11)N(3)O, the aromatic rings at either ends of the -CH(2)-NH- link are twisted by 72.58 (8)°; the hy-droxy substituent is a hydrogen-bond donor to an N atom of the pyrimidine ring. The other N atom of the pyrimidine ring is a hydrogen-bond acceptor to the amino group of an inversion-related mol-ecule.

,4bstruct.-Critical swimming speed (U,,,) is a common rneHsure of the relationship between exercise intensity and duration within the prolonged perforn~nnce nvelope. This relationship is often used to establish wntcr velocity criterin for fishways and culverts; however, the technique involves the nssumptions that fish will choose to move at ( I ) n swimming spced cquivulent to U,,, and (2) a gr...

In the title compound, [CuNa(3)(CH(3)CO(2))(5)(CH(3)COOH)(H(2)O)(2)](n), the Cu(II) atom lies on an inversion center and is coordinated by four O atoms from four acetate ligands, leading to a square-planar geometry. One Na(I) atom, lying on an inversion center, is coordinated by four O atoms from four acetate ligands and two bridging water mol-ecules in a distorted octa-hedral geometry. The oth...

We consider small random perturbations of a large class of nonuniformly hy-perbolic unimodal maps and prove stochastic stability in the strong sense (L 1-convergence of invariant densities) and uniform bounds for the exponential rate of decay of correlations. Our method is based on an analysis of the spectrum of a modiied Perron-Frobenius operator for a tower extension of the Markov chain.

29 ABSTRACT: Background: Hyperkalemia is a common condition, occurring in up to 10% of hospitalized patients. Al though severe hyperkalemia is a life-threatening condition, there is little consistency in the management of high serum potassium. We conducted a quality improvement project aimed at increasing the proportion of hy perkalemia cases managed according to the best available evidence and...

In the title compound, C(22)H(18)O(3), an intra-molecular O-H⋯O hydrogen bond stabilizes the mol-ecular structure, forming an S(6) ring motif. The central benzene ring forms a dihedral angle of 64.74 (5)° with the phenyl ring and a dihedral angle of 5.58 (5)° with the terminal benzene ring. In the crystal, mol-ecules are linked into columns along the a axis via inter-molecular C-H⋯O hydrogen bo...

In the title mol-ecule, C(25)H(30)O(4), the two cyclo-hexene rings adopt envelope conformations. The two hy-droxy groups are involved in the formation of intra-molecular O-H⋯O hydrogen bonds. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules related by translation along the axis a into chains.
