13. Expression of a cloned rat histamine H2 receptor mediating inhibition of arachidonate release and activation of cAMP accumulation.
A DNA, cloned after screening a rat genomic bank with probes derived from the sequence of a putative dog histamine H2 receptor [Gantz, I., Schäffer, M., Delvalle, J., Logsdon, C., Campbell, V., Uhler, M. & Yamada, T. (1991) Proc. Natl. Acad. Sci. USA 88, 429-433], was used to prepare a probe for Northern blot analysis and to transfect Chinese hamster ovary

14. Content of Adenosine Phosphates and Adenylate Energy Charge in Germinating Ponderosa Pine Seeds
An average of 540 picomoles of total adenosine phosphates was found in the embryo of mature seeds of ponderosa pine (Pinus ponderosa Laws.) and 1140 picomoles in the gametophyte. Adenylate energy charges were 0.44 and 0.26, respectively. After stratification, total adenosine phosphates increased 7-fold and 6-fold in embryo and gametophyte, respectively, and

15. Reserve Mobilization in the Arabidopsis Endosperm Fuels Hypocotyl Elongation in the Dark, Is Independent of Abscisic Acid, and Requires PHOSPHOENOLPYRUVATE CARBOXYKINASE1
Arabidopsis thaliana is used as a model system to study triacylglycerol (TAG) accumulation and seed germination in oilseeds. Here, we consider the partitioning of these lipid reserves between embryo and endosperm tissues in the mature seed. The Arabidopsis endosperm accumulates significant quantities of storage lipid, and this is effectively catabolized upon

16. Detection of Borrelia burgdorferi infection in Ixodes dammini ticks with the polymerase chain reaction.
The polymerase chain reaction (PCR) was used to amplify DNA sequences of the etiologic agent of Lyme disease, Borrelia burgdorferi, and was applied to the detection of the spirochete in its tick vector. The target for PCR amplification was the OSP-A gene of strain B31; analysis of isolates from different geographical areas indicated that this gene could be u

17. Electron microscopy and immunocytochemistry in the assessment of renal biopsy specimens: actual and optimal practice.
AIMS: To determine the variation in practice of British renal histopathologists in the use of immunohistochemistry and electron microscopy in the investigation of renal biopsy specimens; to attempt to identify a consensus on what acceptable practice should be; and to satisfy requests from laboratories which have found immunoperoxidase methods unreliable on r

18. Gas Exchange and Carbon Partitioning in the Leaves of Celery (Apium graveolens L.) at Various Levels of Root Zone Salinity.
Both mannitol and sucrose (Suc) are primary photosynthetic products in celery (Apium graveolens L.). In other biological systems mannitol has been shown to serve as a compatible solute or osmoprotectant involved in stress tolerance. Although mannitol, like Suc, is translocated and serves as a reserve carbohydrate in celery, its role in stress tolerance has y

19. The Vaccinia Virus Soluble Alpha/Beta Interferon (IFN) Receptor Binds to the Cell Surface and Protects Cells from the Antiviral Effects of IFN
Poxviruses encode a broad range of proteins that interfere with host immune functions, such as soluble versions of receptors for the cytokines tumor necrosis factor, interleukin-1β, gamma interferon (IFN-γ), IFN-α/β, and chemokines. These virus-encoded cytokine receptors have a profound effect on virus pathogenesis and enable the study of the role of cyt
