    Notes: Twenty-five organoboron compounds were evaluated for their ability to impart flame retardancy properties to a cotton twill fabric. Only those organoboron compounds in which the carbon-to-boron atom ratio was 4 or less imparted flame retardancy at an approximate 20% add-on level; if a halogen atom was also present in the molecule this ratio could be higher than 4. Washfast finishes with six different compounds were developed by either γ-radiation grafting of a vinyl organoboron compound or by chemical curing with hexamethylenediisocyanate, trimethylolmelamine or urea-formaldehyde.

    Notes: Abstract Thirty-one patients diagnosed as having congenital adrenal hyperplasia were given standardized IQ tests. Patients' IQ was found not to be significantly higher than the IQ of nonaffected siblings or the expected IQ from parental values. Thus the adrenogenital syndrome appears to confer no IQ advantage independent of family IQ level.

    Notes: Abstract A sample of 31 patients with congenital adrenal hyperplasia was matched to a control group by sex, age, height, full-scale IQ score, and urban/rural site of residence. Patients and matched controls were tested on measures of masculinity and femininity and on sex-typed tests of cognitive ability. The two groups did not differ significantly on these measures. The finding is in disagreement with earlier reports of “masculinization” of behavior in female patients with congenital adrenal hyperplasia.

    Studies of polypeptide structure by fluorescence techniques. III. Interaction between dye and macromolecule in fluorescent conjugates (1967)

    Notes: The effects of pH on the polarization of fluorescence of dyes dissolved in media of high viscosity or conjugated to polypeptides that undergo no structural transitions indicate that DNS is useful for studying pH-dependent molecular transition over the range pH 2.5-14, whereas fluorescein is useful only over the range pH 6-8. Heating and cooling in aqueous solutions cause no change in the polarization of fluorescein or of DNS; therefore, the dyes themselves do not introduce artifacts into heating studies of the dye conjugates. The interaction between fluorescein or DNS and the molecule to which it is conjugated varies and thus may affect the measurements made with the conjugates: the rotational relaxation times of polylysine, of a copolymer of glutamic acid and lysine, and of lysozyme are approximately twice as long when measured with DNS-conjugates as when measured with fluorescein-conjugates. The explanation for this observation is postulated to lie in the tighter binding between fluorescein and the molecule to which it is conjugated, presumably around the point of its covalent attachment, which makes it a better indicator of the behavior of the rotational kinetic unit of the polypeptide chain. The stronger binding of fluorescein is inferred from two lines of evidence: (1) the fluorescent intensity and ultraviolet spectra of a fluorescein-polylysine conjugate are less susceptible to changes in solvent than those of the DNS conjugate, and (2) the net charge of the polypeptide affects the ionization of fluorescein much less than it affects the ionization of DNS. Additional evidence from previous studies corroborates this conclusion. Thus, it is important to establish the relationship between the fluorescent dye and the molecule to which it is conjugated before using the fluorescence data to calculate rotational relaxation times and other molecular parameters.

    Ovarian follicular development in the pregnant hamster (1964)

    Notes: Follicular activity in the ovary of the pregnant hamster is divided into two periods. During the first eight days (corresponding to the duration of pseudopregnancy) an average of 11 follicles per ovary from 277 to 553 μ are present. From day 10 to 16 of pregnancy, the ovary contains 22 follicles ranging from 277 to 600 μ and larger. The day after parturition, atresia destroys all large multilayered and vesicular follicles.Hamsters injected with human chorionic gonadotropin on day 4 of pregnancy ovulated ten ova, whereas similary treated day 12 animals ovulated 35 eggs. No cyclic follicular activity corresponding to the length of the estrous cycle occurred during gestation. On the contrary, a constant increment of small follicles took place throughout pregnancy.

    A comparison of the in vivo incorporation of S35 methionine by two-celled mouse eggs and blastocysts (1967)

    Notes: Five-day-old mouse blastocysts were transferred into the oviducts of recipients on the second day of pregnancy. S35 methionine was then injected into the recipients and the blastocysts and native 2-celled eggs were recovered six hours later. Radioautographs reveal that the blastocysts incorporate S35 methionine while exposed to the tubal environment to the same degree that they would in the uterus. However, the 2-celled eggs in the same oviducal environment incorporate little or no methionine. It is therefore concluded that the difference in the incorporation of S35 methionine is due to maturational changes in the blastocyst rather than to a deficiency of the labelled amino acid in the tubal lumen.

    Luteotropic complex of the mouse (1969)

    Notes: Pregnant mice were hypophysectomized on day 6 and injected subcutaneously with various hormones from days 6 to 9 to establish the minimal requirements for the maintenance of functional corpora lutea. Luteal activity was assessed by the maintenance of pregnancy, weight of embryonic swellings, mean diameter and morphology of corpora lutea, and vaginal histology.Treatment with 2 mg progesterone maintained pregnancy but not corpora lutea in three of five animals. However, the embryonic swellings were significantly (P 〈 0.0005) smaller than those of pregnant control animals. Pregnancy was maintained in all animals when progesterone was combined with 1 μg of estrone. The weights of embryonic swellings and the degree of vaginal mucification in the combined steroid group were similar to those of intact control animals.Treatment with either ovine prolactin, bovine LH, ovine FSH or estrone failed to maintain corpora lutea or pregnancy. Combined injection of prolactin with LH or estrone did not maintain pregnancy or corpora lutea. On the other hand, treatment with 500 μg of prolactin and 200 μg of FSH maintained pregnancy in 12 of 14 animals. All of the aforementioned parameters of luteal activity were comparable to values in intact, control animals.The data indicate that luteal function in the mouse during the early post-implantation period requires a luteotropic complex rather than a single hormone. Prolactin and FSH constitute the minimal luteotropic complex in the pregnant mouse. The luteotropic activity of FSH was not due to its contamination with LH and the effect of FSH was apparently not mediated through estrogen secretion, since pregnancy was not maintained by prolactin and estrone.

    Quantitative aspects of follicular development in the untreated and PMS-treated cyclic hamster (1974)

    Notes: Hamsters injected at 0900 on day 1 of the cycle (metestrus) with either 0, 5 or 15 IU pregnant mare's serum (PMS) were killed at 1500 of days 1 to 4 of the cycle and the ovaries prepared for light microscopy and for a quantitative evaluation of follicular development. In the untreated cyclic hamster, the maximal number of preantral follicles with eight or more layers of granulosa cells occurred between the afternoon of day 4 (proestrus) and day 1, coinciding with the highest blood levels of FSH and LH. It is concluded that the elevated preovulatory levels of gonadotropins not only induce the ovulation of the mature antral follicles but at the same time recruit the next set of follicles for development during the new cycle.By the afternoon of day 1, treatment with either 5 or 15 IU PMS recruited more follicles into large preantral and incipient antral stages than in the untreated hamsters. However, by day 2 the pattern of follicular distribution was similar between the 5 IU PMS and untreated group whereas considerably more antral follicles had differentiated in the animals given 15 IU PMS. The ability of 15 IU PMS to elicit superovulation therefore depends on the levels being initially high enough to mature more follicles at critical stages of their development; the prolonged biological half life of PMS then sustains these follicles throughout the cycle.
