Changes in synaptic efficacy in rat brain slices following extremely low-frequency magnetic field exposure at embryonic and early postnatal age.

An earlier study demonstrated changes in synaptic efficacy and seizure susceptibility in adult rat brain slices following extremely low-frequency magnetic field (ELF-MF) exposure. The developing embryonic and early postnatal brain may be even more sensitive to MF exposure. The aim of the present study was to determine the effects of a long-term ELF-MF (0.

Straight talk. New approaches in healthcare. Capital financing: beyond the shores of your typical transaction.

If you're in the market to renovate or expand but are concerned about overloading your balance sheet with debt or if you plan to build a for-profit facility, consider a Design, Build, Finance, and Operate (DBFO) arrangement. In such deals, experts in finance, construction, real estate, and support-service provision manage risk and day-to-day responsibility for facility management. Evaluating alternatives to tax-exempt financing is a critical piece of capital planning today because competition for traditional sources of funding has become global.

Effects of the New Fathers Network on first-time fathers' parenting self-efficacy and parenting satisfaction during the transition to parenthood.

The effectiveness of an Internet-based intervention, the New Fathers Network, was tested in improving first-time fathers' parenting self-efficacy and parenting satisfaction during the first 8 weeks following their infants' birth as compared with no intervention (Comparison Group). Parenting self-efficacy and satisfaction scores for the Intervention Group significantly improved from 4 to 8 weeks; parenting self-efficacy and satisfaction scores for the Comparison Group to which no intervention was given did not change significantly. Participants were primarily satisfied with the New Fathers Network.

Marital and parenting satisfaction and infant care self-efficacy during the transition to parenthood: the effect of infant sex.

The purpose of this follow-up study was to examine the effect of infant sex on changes in and differences between parents' reports of infant care self-efficacy and parenting and marital satisfaction from 4 months to 12 months after the birth of their first child. A convenience sample of 32 couples was selected from 44 couples who participated in a longitudinal study of the development of parenting satisfaction and infant care self-efficacy during the first 4 months after the birth of a first child (Brage Hudson, Elek, Fleck, 2001). Couples completed a demographic questionnaire, the Infant Care Survey (ICS, Froman Owen, 1989), the What Being the Parent of a New Baby is Like--Revised Questionnaire (WPBL-R, Pridham Chang, 1989), and the Dyadic Adjustment Scale (DAS, Spanier, 1976, 1989) 4 and 12 months postpartum.

First-time mothers' and fathers' transition to parenthood: infant care self-efficacy, parenting satisfaction, and infant sex.

The threefold purposes of our study were to determine differences between first-time mothers' and fathers' development of infant care self-efficacy and parenting satisfaction, relationships between mothers' and fathers' infant care self-efficacy and parenting satisfaction, and the effect of infant sex on the development of mothers' and fathers' infant care self-efficacy and parenting satisfaction during the first 4 months following the infant's birth. A convenience sample of 44 couples in a midwestern state completed the Demographic Questionnaire, the Infant Care Survey, and What Being the Parent of a New Baby is Like-Revised. Fathers' reports of infant care self-efficacy increased linearly during the first 4 months following the infant's birth while mothers' reports of infant care self-efficacy increased linearly during the first 3 months.

Depression, self-esteem, loneliness, and social support among adolescent mothers participating in the new parents project.

The purpose of this pilot study was to examine levels of depression, self-esteem, loneliness, and social support, and the relationships between these variables, among adolescent mothers participating in the New Parents Project (formerly called the Young Parents Project). The sample consisted of 21 adolescent mothers recruited from three primary health care practices in different Midwestern cities. It was found that depression scores were in the high range (CES-DC > 15) for 53% of the participants.

Young Parents Project: a 21st-century nursing intervention.

The purpose of this exploratory, descriptive pilot study was to describe the usage of the Young Parents Project, a computer network offering health information and support, to adolescent mothers. Nine midwestern adolescent mothers were provided a computer so they could access the Young Parents Project in their homes. Participants gained access to the computer network 834 times for a total of 7,046 minutes during the year of the study.

Expectant parents' experience with fatigue and sleep during pregnancy.

Background: Although both expectant mothers and expectant fathers complain of fatigue during the last trimester of pregnancy, studies have focused exclusively on mothers. This pilot study examined parents' levels of morning or evening fatigue, number of uninterrupted sleep periods and length of sleep during the last trimester of pregnancy; and the relationship of sleep to parents' reports of fatigue.

Methods: Data were collected from 24 midwestern, nulliparous couples, who completed the Visual Analog Scale for Fatigue each morning and each evening on 4 consecutive days during the last trimester.

Neurogenic hypercholesterolemia: influence of autonomic drugs.

Eleven substances capable of either augmenting or depleting the alpha- and - beta-adrenergic capacities of the autonomic nervous system were administered to rats exhibiting hypothalamic hypercholesterolemia and to normal controls. Only the beta-adrenergic blocking agents propranolol and possibly 6-OH dopamine were observed to alter (raise) the serum cholesterol concentration, and this occurred in both experimental and control animals. Neither atropine, nor the serotonin-depleting agent, rho-chlorophenylalanine, nor the serotonin-antagonist cyproheptadine, were observed to alter serum cholesterol level.

Further studies concerning glucagon-induced hypocholesterolemia.

Some of the possible mechanisms responsible for the hypocholesterolemic effect of glucagon were investigated. Glucagon was found to inhibit the intestinal absorption of cholesterol. In addition, it was found to either hasten the rate of egress of lipoprotein cholesterol from the blood into the liver or to retard the rate of re-entry of cholesterol from the liver into the blood.
