POWERS J. B. AND S. S. WlNANS. Sexual behavior in peripherally anosmic male hamsters. PHYSIOL. BEHAV 10(2) 361 368, 1973.-Sexually experienced and inexperienced male hamsters mated normally after they had been rendered temporarily anosmic by intranasal zinc sulfate treatment (Experiment 1), in contrast to the complete absence of sexual behavior following removal of the olfactory bulbs. The effi...

The reaction of [60]fullerene with dimethyl malonate and diethyl malonate in the presence of manganese(III) acetate dihydrate (Mn(OAc)3.2H2O) for 20 min afforded singly bonded [60]fullerene dimers 1a and 1b in a 1,4-addition pattern. When the reaction time was extended to 1 h, 1,4-bisadducts 2a and 2b were obtained. Unsymmetrical 1,4-adduct 5 and C2 symmetrical 1,16-bisadduct 6 were obtained wh...

In the title coordination polymer, {[Zn(C(9)H(7)NO(4))(C(10)H(14)N(4))]·2H(2)O}(n), the Zn(II) ion displays a distorted tetra-hedral geometry with two imidazole N atoms from two 1,1'-(butane-1,4-di-yl)bis-(imidazole) (bbi) ligands and two carboxyl-ate O atoms from two 2,6-dimethyl-pyridine-3,5-dicarboxyl-ate (dpdc) ligands. The bbi and dpdc ligands bridge the Zn(II) ions, forming layers paralle...

The asymmetric unit of the title complex, [Zn(H(2)O)(6)](C(10)H(5)O(8))(2)·2C(11)H(6)N(2)O·2H(2)O, contains one half of the complex cation with the Zn(II) ion located on an inversion center, a monovalent 2,4,5-tricarboxybenzoate (1,2,4,5-BTC) counter-anion, a 4,5-diaza-fluoren-9-one (DAFO) mol-ecule and an uncoordinated water mol-ecule. In the crystal structure, O-H⋯O and O-H⋯N hydrogen bonds l...

The Zn(II) atom in the title polymeric compound, {[Zn(C(8)H(6)NO(4))(2)(H(2)O)(2)]·2H(2)O}(n), lies on a center of inversion and is coordinated by two amine N atoms and two carboxyl-ate O atoms from two 3-amino-5-carb-oxy-benzoate anions along with two water mol-ecules in a distorted octa-hedral geometry. The bridging nature of the anion generates a layer motif parallel to (100). Hydrogen bonds...

2-Mercaptoethanol inhibits growth of Aspergillus parasiticus NRRL 3240 and aflatoxin formation by the fungus. When added to the resuspended medium, 2-mercaptoethanol inhibited [1-14C]acetate incorporation into both aflatoxins and neutral lipids, thereby showing that it acts at an early stage of aflatoxin biosynthesis. The inhibition is probably due to its chelating action on zinc, which is esse...

Whereas the addition of four moles of zinc acetate to one of normal human haemoglobin at pH 7.4 results in a clear solution, addition to unstable haemoglobin results in precipitate formation. Within certain limits no false-positive results are obtained with methaemoglobin, and with fetal haemoglobin. With excess zinc, normal haemoglobin also precipitates, but this process is reversible and can ...

treatment we adopted was constitutional, a carefurregulation of diet, and the ordinary local applications of zinc ointment zinc powder, &c. Under it he improved considerably, and the disease disappeared on the face, ear, and legs, but the patches on the hands and arms were most obstinate. Boracic acid in ointment and lotion, carbolic acid, zinc ointment, solution of acetate of lead, nitrate of ...
