- Identification of differentially expressed proteins at four growing stages in chicken liver
- ABSTRACT : Because of high growth rate and large deposition of fat in the abdomen, the chicken has been used as a model organism for understanding lipid metabolism, fattening and growing. In this study, differentially expression of proteins in chicken liver, one of the important organs for lipid metabolism, has...

- Flower visitation by adult shore flies at an inland site in Florida
- Shore flies Ephydridae are small acalypterates whose larvae are usually aquatic or semi-aquatic. Adult feeding habits are varied and known for only a small proportion of species. Most adults consume algae or bacterial slurries, but some are predators on smaller arthropods, scavengers, or nectar feeders (Wirth et al. 1987). At...

- Time-resolved Singlet Oxygen Phosphorescence Measurements from Photosensitized Experiments in Single Cells: Effects of Oxygen Diffusion and Oxygen Concentration
- ABSTRACT Time-resolved singlet oxygen, O2(a^sup 1^?^sub g^), phosphorescence experiments have been performed in single cells upon pulsed laser irradiation of a photosensitizer incorporated into the cell. Data recorded as a function of the partial pressure of ambient oxygen to which the cell is exposed reflect apparent values for the intracellular...

- Kurarinol, tyrosinase inhibitor isolated from the root of Sophora flavescens
- Abstract It is well known that flavanones, sophoraflavanone G 1, kurarinone 2, and kurarinol 3, from the root of Sophora flavescens, have extremely strong tyrosinase inhibitory activity. This study delineates the principal pharmacological features of kurarinol 3 that lead to inhibition of the oxidation of L-tyrosine to melanin by...

- A Role for Internal Water Molecules in Proton Affinity Changes in the Schiff Base and Asp85 for One-way Proton Transfer in Bacteriorhodopsin[dagger]
- ABSTRACT Light-induced proton pumping in bacteriorhodospin is carried out through five proton transfer steps. We propose that the proton transfer to Asp85 from the Schiff base in the L-to-M transition is accompanied by the relocation of a water cluster on the cytoplasmic side of the Schiff base from a site...

- A shilling for Queen Elizabeth: the era of state regulation of church attendance in England, 1552-1969
- Throughout Christian history, churchgoing has been widely regarded as one of the most important and tangible expressions of religious observance. Yet, before the Reformation, failure to attend services was subject solely to ecclesiastical sanctions, such as admonition, penance, and excommunication, as applied by the Episcopal courts. Partly as a consequence,...

- Effects of experimental egg composition on rejection by village weavers
- It is advantageous for individual birds to be able to recognize their own eggs and to remove foreign eggs from their nests when exposed to brood parasitism (Davies and Brooke 1989, Rothstein 1990, Ortega 1998, Peer et al. 2005). Addition of experimental eggs to nests of Old World cuckoo (Cuculus...

- Comparison of the [[sup.2][H.sub.5]]phenylalanine model with the [1-[sup.13]C]leucine method to determine whole body protein synthesis and degradation in sheep fed at two levels
- ABSTRACT : The [[sup.2][H.sub.5]]phenylalanine model was compared with the [1-[sup.13]C]leucine method to determine whole body protein synthesis WBPS and degradation WBPD in sheep fed at two levels. The animals were fed either 103 (M-diet) or 151 (H-diet) kcal ME/[kg.sup.0.75]/day once daily in a crossover design for 21 days ere simultaneously...

- Pentecostalism beyond belief: trust and democracy in a Malawian township
- ABSTRACT The concept of belief, when applied in its strong sense, assumes an inner state that sets believers apart from non-believers. This article suggests that a concept of trust is more appropriate for the study of the religious orientation among Pentecostal Christians in Chinsapo, an impoverished township in Malawi's...
