Insecticide resistance status, esterase activity, and electromorphs from mosquito populations of Culex quinquefasciatus Say (Diptera: Culicidae), in Houston (Harris County), Texas.
TLDR
Results indicate the onset of a fragile situation for mosquito control that should be further analyzed to effectively maintain the SLE prevention program for Harris County. Expand
Partial characterization and solubilization of receptors for atrial natriuretic factor in rat glomeruli.
TLDR
Radioiodinated synthetic ANF bound to a single class of high affinity sites with a density of 390 +/- 230 fmole/mg protein, and ANF-related peptides interact generally in the same way with non-solubilized and solubilization receptors, indicating a fully preserved specificity of the receptors.

Inhibition of protein phosphatases‐1 and ‐2A with acanthifolicin
TLDR
Pure acanthifolicin/okadaic acid methyl ester may be useful as specific inhibitors of PP2A at 1–10 μM concentrations in vitro and perhaps in vivo and indicate that a region on these toxins important for PP1/2A inhibition comprises the single carboxyl group. Expand
Identification and characterization of atrial natriuretic factor receptors in the rat retina.
TLDR
The demonstration of specific high-affinity ANF receptors suggests that the peptide may act as a neurotransmitter or neuromodulator in the retina and central and peripheral ANF-binding sites have somewhat similar structural requirements. Expand
Structure-activity relationships of atrial natriuretic factor (ANF). I. Natriuretic activity and relaxation of intestinal smooth muscle.
TLDR
Atrial natriuretic factor-related peptides produced from synthetic ANF either by chemical hydrolysis at the N-terminal end or by treatment with carboxypeptidases at the C-terminals were characterized in vivo and in vitro by relaxation of contracted intestinal smooth muscle. Expand
Glomerular ANF receptor regulation during changes in sodium and water metabolism.
TLDR
It is concluded that an inverse correlation exists between ANF plasma concentration and renal glomerular ANF receptor sites, whereas the inverse occurred with a high-salt consumption. Expand
Radioreceptor assay for atrial natriuretic factor.
TLDR
A rapid, sensitive, and simple radioreceptor assay (RRA), based on the presence of high-affinity binding sites for ANF in rat glomeruli, suggests that the immunoreactive material found in rat plasma and atrial homogenates also displays biological activity. Expand
Solubilization and molecular characterization of the atrial natriuretic peptide (ANP) receptor in human platelets: comparison with ANP receptors in rat tissues.
TLDR
The results show that the ANP receptor in human platelets is heterogeneous, with one nonreducible species with of 125,000 Mr, another of similar Mr containing two disulfide-linked subunits of 70,000Mr, and, to a lesser extent, a non reducible 70-kDa species, in agreement with findings in other tissues in experimental animals.

The hydrogen evolution reaction in basic medium on iron electrodeposited with heteropolyacids
Iron was electrodeposited from dilute aqueous solutions of iron sulphate, containing PW12O403−, PMo12O403− or MoO42− ions. It was shown that improvement in the overpotential and in the exchangeExpand
