This work investigates the existence of sex differences in the volume and number of neurons and glial cells in the bed nucleus of the accessory olfactory tract (BAOT). Males showed larger volume and number of cells than female rats. Early postnatal (day 1 after birth) orchidectomy in males, and androgenization in females, reversed these differences. No sex(More)
OBJECTIVES To determine whether rates of tooth loss, periodontal disease progression, and caries incidence predict cognitive decline in men. DESIGN Prospective study. SETTING Community-dwelling men enrolled in the Veterans Affairs Dental Longitudinal Study. PARTICIPANTS Five hundred ninety-seven dentate men aged 28 to 70 at study baseline who have(More)
In the present study the regulatory action of the non-aromatic androgen dihydrotestoterone (DHT) on the volume of the sexually dimorphic bed nucleus of the accessory olfactory tract (BAOT) was investigated. Postnatal treatment with DHT (180 micrograms day-1) between days 6 and 20 (D6-D20) induced, in gonadally intact male rats, a drastic reduction in the(More)
Orchidectomized males injected with a single dose of estradiol benzoate (EB) on the day of birth (D1) showed a volume and neuron number in the nucleus of the accessory olfactory tract (BAOT) similar to that of control males. However, orchidectomized males and those orchidectomized and given a single dose of DHT on D1 showed a decrease in BAOT volume and(More)
The effects of postnatal (on day 1 after birth) male castration and female androgenization on accessory olfactory bulb (AOB) volume were studied. Control males showed greater values than females in AOB volume. Postnatal treatments abolished and inverted these differences. It is suggested that the AOB development is influenced by sex steroids during at least(More)
The effects of postnatal (on day 1 after birth) male castration and female androgenization on accessory olfactory bulb (AOB) mitral cells population were studied. Control males showed a greater number of AOB mitral cells than females. Postnatal treatments abolished and inverted these differences. It is suggested that the population of AOB mitral cells is(More)
The effects of postnatal male castration on day 1 (D1) after birth and female androgenization on accessory olfactory bulb (AOB) light and dark granule cell populations were studied. Control males showed a greater number of both light and dark AOB granule cells than females. Postnatal treatment reversed these differences in the light granule cells. Female(More)
The regulatory action of the non-aromatizable androgen dihydrotestosterone (DHT) on sexual differentiation of the volume of the rat accessory olfactory bulb (AOB) was studied. Postnatal treatment with DHT (180 micrograms/day) carried out daily between days 6 and 20 produced a drastic reduction in overall AOB size and that of its constituent neural layers in(More)
The volume and neuron number of the sexually dimorphic accessory olfactory bulb and locus coeruleus are altered by early postnatal exposure (from the day of birth to postnatal day 16) to diazepam. After diazepam treatment, both volume and neuron number were decreased in the male accessory olfactory bulb and in the female locus coeruleus. These results(More)
