What's the difference between dinaphthyl and naphthyl?
Dinaphthyl
Definition:
(n.) A colorless, crystalline hydrocarbon, C20H14, obtained from naphthylene, and consisting of a doubled naphthylene radical.
Example Sentences:

(2) These ionophores include macrocyclic polyethers with dinaphthyl subunits and azocrown ether with nitrogen donor atoms.
(3) The chiral separation of diltiazem hydrochloride and timetoquinol hydrochloride was successfully achieved by use of sodium taurodeoxycholate under neutral conditions, although enantiomers of carboline derivatives A and B and 2,2'-dihydroxy-1,1'-dinaphthyl were resolved with all the bile salts under conditions from neutral to alkaline.
(4) The SH staining procedure with 2,2'-dihydroxy-6,6'-dinaphthyl disulfide applied after IEF appeared to be useful, specific, and reproducible.
Naphthyl
Definition:
(n.) A hydrocarbon radical regarded as the essential residue of naphthalene.
Example Sentences:

(2) Tumor cells were unreactive for alpha-naphthyl butyrate esterase (ANBE) and adenosine triphosphatase (ATP).
(3) T lymphocyte subsets were identified with monoclonal antibodies and pattern of alpha-naphthyl-acetate esterase (ANAE) staining pattern in the case of peripheral blood and ANAE staining pattern with thyroid aspirate smears.
(4) Functional characteristics such as nitroblue-tetrazolium reduction, alpha-naphthyl butyrate esterase activity, and phagocytic capability occurred.
(5) The calcium channel blockers 'DMDP' [N-3,4-dimethoxyphenethyl)-N-methyl-2-(2-naphthyl-m-dithane-2-prop ylamine)] and verapamil inhibited the active efflux of adriamycin from adriamycin-resistant P388 leukemia cells but had no effect on the drug-sensitive cell line.
(6) 4-Nitrophenyl glucuronide and also naphthyl glucuronide were without effect both in hepatocytes and microsomes.

(8) Acid phosphatase, beta-glucuronidase, and alpha-naphthyl acetate esterase were positive in enzyme histochemical examinations.
(9) The effects of a novel synthetic fatty acid derivative (TEI-8005:(7E)-8-(2-naphthyl)-5,6-trans-5, 6-methano-7-octenoic acid) on arachidonic acid metabolism in some cultured cells were studied.
(10) We have previously shown that non-proliferating human T- but not B-lymphocytes contain demonstrable amounts of acid alpha-naphthyl acetate esterase (ANAE).
(11) The selective use of CD3, CD4, CD8, HNK-1 monoclonal antibodies and of cytochemical stains (acid phosphatase and alpha-naphthyl butyrate esterase) for characterization of this disorder is discussed.
(12) Oxythioquinox, Plictran (tricyclohexylhydroxytin), Nissol [2-fluoro-N-methyl-N-(1-naphthyl)acetamide], and chlordimeform are examples of quinoxaline, organotin, organofluorine, and formamidine acaricides, respectively.
(13) Infiltrating macrophages in tumor were identified in paraffin section by alpha-naphthyl butyrate esterase stain and subdivided by electron microscopy according to the peroxidase activity.
(15) The non-carcinogens chosen were 4-nitro-o-phenylenediamine, p-phenylenediamine dihydrochloride, 3-nitropropionic acid, dichlorvos, 2-(chloromethyl)pyridine, N-(1-naphthyl)ethylenediamine 2HCl, O-anthranilic acid, 4-nitroanthranilic acid, anilazine and triphenyltin hydroxide.

(17) values were similar for all the substrates used (lactose, phenyl beta-galactoside, o-nitrophenyl beta-galactoside, p-nitrophenyl beta-galactoside and 6-bromo-2-naphthyl beta-galactoside).
(18) Incubation of 2-naphthyl isothiocyanate, microsomes, and NADPH yielded either N,N'-di-2-naphthylurea or, on inclusion of 2-aminofluorene in the incubations, N-2-naphthyl-N'-2-fluorenylurea.
(19) Polymorphism of placental alkaline phosphatase (PL) was investigated in 120 Japanese placentae by means of starch gel electrophoresis and an improved staining method for the isoenzymes using naphthol AS-MX phosphate as substrate instead of beta-naphthyl phosphate.
(20) PDMP did not block other aspects of phorbol ester-induced macrophage differentiation including growth inhibition, expression of mRNA transcripts for the proto-oncogenes c-fos and c-myc, development of the specific enzyme markers alpha-naphthyl acetate esterase and acid phosphatase, and the gross morphologic changes associated with macrophage differentiation.
