1. 65Zn2+ transport processes of isolated gill epithelial cells of the American lobster Homarus americanus / Caracterização do transporte de zinco em células isoladas do epitélio branquial da lagosta Homarus americanus
Os filamentos branquiais da lagosta Americana, Homarus americanus, foram dissociados em solução salina fisiológica e os diversos tipos celulares separados em gradiente de 30, 40, 50 e 80% de sacarose através de centrifugação de alta velocidade. As células provenientes de cada solução de sacarose foram incubadas em 65Zn2+ visando caracterizar a tomad

2. Microfibrils provide non-linear elastic behaviour in the abdominal artery of the lobster Homarus americanus.
1. Microfibrils are becoming increasingly recognized as an important component of the extra-cellular matrix. However, almost nothing is known about their mechanical role in the diversity of tissues in which they are found. 2. Microfibrils form the principal structural component in the wall of the abdominal artery of the lobster Homarus americanus. We have us

3. Cs2SO4 Gradients Containing Both Hg2+ and Ag+ Effect the Complete Separation of Satellite Deoxyribonucleic Acids Having Identical Densities in Neutral CsCl Gradients
A combination of both Ag+ and Hg2+ in Cs2SO4 effects the complete separation of two DNAs having identical densities in CsCl. Satellite DNAs of hermit crab, Pagurus pollicaris, and lobster, Homarus americanus, have been isolated by this means.

4. Thermal acclimation and stress in the American lobster, Homarus americanus: equivalent temperature shifts elicit unique gene expression patterns for molecular chaperones and polyubiquitin
Using homologous molecular probes, we examined the influence of equivalent temperature shifts on the in vivo expression of genes coding for a constitutive heat shock protein (Hsc70), heat shock proteins (Hsps) (Hsp70 and Hsp90), and polyubiquitin, after acclimation in the American lobster, Homarus americanus. We acclimated sibling, intermolt, juvenile male l

5. The peptide hormone pQDLDHVFLRFamide (crustacean myosuppressin) modulates the Homarus americanus cardiac neuromuscular system at multiple sites
pQDLDHVFLRFamide is a highly conserved crustacean neuropeptide with a structure that places it within the myosuppressin subfamily of the FMRFamide-like peptides. Despite its apparent ubiquitous conservation in decapod crustaceans, the paracrine and/or endocrine roles played by pQDLDHVFLRFamide remain largely unknown. We have examined the actions of this pept

6. Agglutination of Streptococcus suis by sialic acid-binding lectins.
The 35 Streptococcus suis capsular-type reference strains as well as 45 field strains of type 2 were tested with sialic acid-binding lectins from Sambucus nigra (SNA I), Triticum vulgaris, Maackia amurensis, Homarus americanus, and Limax flavus. Only types 1, 1/2, 2, 14, 15, and 16 agglutinated with SNA I and/or the T. vulgaris lectin. All field strains aggl

7. ORIENTATION AND MOTION OF AMPHIPHILIC SPIN LABELS IN MEMBRANES*
The paramagnetic resonance spectra of N-oxyl-4′,′-dimethyloxazolidine derivatives of 12-ketostearic acid, 5-ketostearic acid, 5-ketotricosanoic acid, and 5α-androstan-3-one-17β-ol have been observed in sonicated phospholipid dispersions, the walking-leg nerve fibers of Homarus americanus, and in erythrocytes oriented by hydrodynamic shear. The preferre

8. Characterization of Vibrio fluvialis-Like Strains Implicated in Limp Lobster Disease
Studies were undertaken to characterize and determine the pathogenic mechanisms involved in a newly described systemic disease in Homarus americanus (American lobster) caused by a Vibrio fluvialis-like microorganism. Nineteen isolates were obtained from eight of nine lobsters sampled. Biochemically, the isolates resembled V. fluvialis, and the isolates grew
