13. Concorrencia em linguagens de comando
A execução de programas é uma das formas de reutilização de software mais bem sucedidas graças a um módulo que atua entre o usuário e o núcleo do sistema operacional. Estes módulos permitem que o usuário tenha acesso a uma máquina virtual de nível superior àquela fornecida pelos serviços do sistema. Originalmente estes módulos processavam ord

14. Verification of differential gene transcription using virtual northern blotting
We introduce here an alternative to conventional northern blotting that requires only minute amounts of RNA. This has been achieved by modification of methods currently used for the mapping of mRNA 5'-terminal ends. The terminal desoxynucleotidyl transferase-mediated G-tailing, cap finder, ligation-anchored and RNA ligase-mediated approachesfollowed by polym

15. Structure of human hemopexin: O-glycosyl and N-glycosyl sites and unusual clustering of tryptophan residues.
The primary structure of human hemopexin is being deduced from sequence analysis of a series of peptides obtained from chemical and enzymatic digests of the protein. Human hemopexin consists of about 440 amino acid residues. It has five sites of attachment of glucosamine oligosaccharides at the signal sequence of Asn-X-Thr/Ser. A unique structural feature is

16. Distinct mutations in the glycogen debranching enzyme found in glycogen storage disease type III lead to impairment in diverse cellular functions
Glycogen storage disease type III (GSDIII) is a metabolic disorder characterized by a deficiency in the glycogen debranching enzyme, amylo-1,6-glucosidase,4-α-glucanotransferase (AGL). Patients with GSDIII commonly exhibit hypoglycemia, along with variable organ dysfunction of the liver, muscle or heart tissues. The AGL protein binds to glycogen through its

17. Structure of platelet glycoprotein IIIa. A common subunit for two different membrane receptors.
The platelet membrane glycoprotein IIb/IIIa complex is a member of a family of alpha/beta heterodimers that function as receptors for adhesive proteins. In this report we describe the structure of the human beta subunit GPIIIa deduced from an analysis of 4.0 kb of overlapping cDNA sequences isolated from a human erythroleukemia (HEL) cell cDNA expression lib

18. Interaction of p53 with its consensus DNA-binding site.
We have analyzed the specific interaction of murine p53 with the consensus DNA-binding sequence 5'-AGACATGCCT-AGACATGCCT-3'. We used segments of p53 lacking the C-terminal, nonspecific DNA-binding domain because the presence of an autonomous nonspecific DNA-binding domain in wild-type p53 would complicate analysis of site-specific DNA binding. p53 amino acid

19. On the mechanism by which adenosine receptor activation inhibits the release of acetylcholine from motor nerve endings.
The process by which adenosine receptor agonists inhibit the evoked release of acetylcholine (ACh) was studied at motor nerve endings to frog skeletal muscle. Adenosine and 2-chloroadenosine were employed as agonists. Each agonist reduced the mean number of ACh packets released synchronously in response to a nerve impulse (m). Adenosine was from one to two o
