Effects of diverse androgens on the sexual behavior and morphology of castrated male quail

Effects of diverse androgens on the sexual behavior and morphology of castrated male quail. Adkins, Elizabeth Kocher (Dep. Psychol., Cornell Univ., Ithaca, N. Y., USA). Horm. Behav., 8(2), 201-7 (English) 1977. CODEN: HOBEAO. DOCUMENT TYPE: Journal CA Section: 2 (Hormone Pharmacology) Section cross-reference(s): 12 Castrated male Japanese quail were injected for 15 days with 1 mg/day of testosterone propionate (I) [57-85-2], testosterone (II) [58-22-0], androstenedione (AE) [63-05-8], androsterone (AO) [53-41-8], 5a-dihydrotestosterone benzoate (5a-DHTB) [1057-07-4], 5b-dihydrotestosterone (5b-DHT) [571-22-2], or with oil. Copulation was activated to a significant extent only by II and I. Strutting was activated only by I, II, and AE. Proctodeal (foam) glands were well-developed in birds injected with I, II, AE, or 5a-DHTB. Addnl. data were obtained following implantation of pellets of cryst. I, AE, AO, or 5a-DHT. I pellets activated couplation, but AO and 5a-DHT pellets did not. Conversion of androgen to estrogen may be necessary for the activation of copulation in the male quail.

Preparation of a polymer-supported diol and its use in isolating aldehydes and ketones from mixtures and as a protecting group for aldehydes and ketones. Hodge, Philip; Waterhouse, Janette (Chem.Several substances are used for example 1057-07-4 and 846-46-8 which are their cas registry numbers. Dep., Univ. Lancaster, Lancaster LA1 4YA, UK). J. Chem. Soc., Perkin Trans. 1, (10), 2319-23 (English) 1983. CODEN: JCPRB4. ISSN: 0300-922X. DOCUMENT TYPE: Journal CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) Section cross-reference(s): 23, 32, 35 Condensation reaction of crosslinked chloromethylated polystyrenes with HSCH2CH(OH)CH2OH and NaOH under phase-transfer conditions gave polymers contg. [CH2CH[C6H4CH2SCH2CH(OH)CH2OH-4]]n groups. A no. of arom. and aliph. aldehydes and ketones formed acetals with these compds.; they were released by treatment in aq. dioxane contg. p-MeC6H4SO3H. The polymer-supported diol was also used to isolate aldehydes and ketones from mixts. with other compds. and to sep. a 3-oxo steroid from 17- or 20- oxo steroids. The diol was also used to protect the CHO group in the prepn. of BzO(CH2)10CHO from H2C:CH(CH2)8CHO. .
