Expression of pituitary adenylate cyclase activating peptide in the uterine cervix, lumbosacral dorsal root ganglia and spinal cord of rats during pregnancy.

The uterine cervix is highly innervated by the sensory nerves containing neuropeptides which change during pregnancy and are regulated, in part, by estrogen. These neuropeptides act as transmitters both in the spinal cord and cervix. The present…

The effects of pregnancy and estrogen on the expression of calcitonin gene-related peptide (CGRP) in the uterine cervix, dorsal root ganglia and spinal cord.

Before parturition the uterine cervix undergoes a ripening process ("softens" and dilates) to allow passage of the fetus at term. The exact mechanism(s) responsible for cervical ripening are unknown, though a role for peptidergic sensory neurons is…

Developmental pyrethroid exposure causes long-term decreases of neuronal sodium channel expression.

Pyrethroid insecticide use has increased over recent years because of their low to moderate acute toxicity in mammals. However, there is increasing concern over the potential detrimental effects of pyrethroids on developing animals. Most recently, we…

Parity decreases methamphetamine-induced striatal dopaminergic perturbation.

The role of parity upon methamphetamine-induced neurotoxicity of the striatal dopaminergic system was assessed. Female CD-1 mice either remained nulliparous or underwent one or three complete pregnancies and were designated as the 0, 1 or 3 pregnancy…

Another Reason to Avoid Second-Hand Smoke.

Perceptions of child protective services among pregnant or recently pregnant, opioid-using women in substance abuse treatment.

Pregnant, opioid-using women represent a challenge to healthcare providers attempting to engage them in prenatal and substance abuse services. Limited, primarily international research suggests that child welfare clients have mixed feelings about…

Pregnancy zone protein is a carrier and modulator of placental protein-14 in

A successful pregnancy can only occur when the maternal immune system fails to attack the allogeneic fetus. Two plasma proteins with described immunoregulatory activities, pregnancy zone protein (PZP) and placental protein-14 (PP14; also known as…

Prenatal cocaine exposure leads to enhanced long-term potentiation in region CA1 of hippocampus.

Cocaine use by pregnant women is currently of concern for its social and economic impact. Clinical studies of cocaine exposed offspring are limited by methodological constraints. In this study we used a rabbit model to examine the effects of…

Chlamydia trachomatis and Adverse Pregnancy Outcomes: Meta-analysis of Patients With and Without Infection.

OBJECTIVES: We conducted a meta-analysis to determine the association between Chlamydia trachomatis and adverse perinatal outcomes. METHODS: Electronic databases were searched between 1970 and 2013. Included studies reported perinatal outcomes in…

The Personal Social Networks of Resettled Bhutanese Refugees During Pregnancy in the United States: A Social Network Analysis.

Women comprise 50% of the refugee population, 25% of whom are of reproductive age. Female refugees are at risk for experiencing significant hardships associated with the refugee experience, including after resettlement. For refugee women, the…

Ileal pouch perforation in pregnancy: report of a case and review of the literature.

Acute abdominal pain, especially in the presence of free intra-abdominal air, in a pregnant patient who has previously undergone ileal pouch-anal anastomosis may be a result of acute perforation of the pouch. The case of a 30-year-old multigravida…

Depression, anxiety, and mental health service experiences of women with a twin-twin transfusion syndrome pregnancy.

Symptoms of emotional distress during and after pregnancy may be introduced or exacerbated by unexpected medical conditions in the mother or fetus. Twin-twin transfusion syndrome (TTTS), which accounts for 17% of fetal deaths in twins and entails…

P2X receptors in the rat uterine cervix, lumbosacral dorsal root ganglia, and spinal cord during pregnancy.

ATP, an intracellular energy source, is released from cells during tissue stress, damage, or inflammation. The P2X subtype of the ATP receptor is expressed in rat dorsal root ganglion (DRG) cells, spinal cord dorsal horn, and axons in peripheral…

Spontaneous prolonged hypertonic uterine contractions (essential uterine hypertonus) and a possible infective etiology.

The management of a pregnant woman presenting with prolonged hypertonic uterine contractions (essential uterine hypertonus) and mildly elevated temperature at term is described. Histology of the placenta, cord and membranes, following delivery,…

Inhibition of nerve growth factor-stimulated neurite outgrowth by methylamine-modified alpha 2-macroglobulin.

alpha 2-Macroglobulin (alpha 2M) is a rather ubiquitous protein in extracellular spaces of mammals. It is an inhibitor of endopeptidases, can be modified by aliphatic amines, and combines with a number of hormones/cytokines such as beta-nerve growth…

Activation and circuitry of uterine-cervix-related neurons in the lumbosacral dorsal root ganglia and spinal cord at parturition.

Stimulation of the uterine cervix at parturition activates neural circuits involving primary sensory nerves and supraspinally projecting neurons of the lumbosacral spinal cord, resulting in output of hypothalamic neurohormones. Dorsal root ganglia…

Estrogen receptor-alpha and neural circuits to the spinal cord during pregnancy.

Estrogen receptor immunoreactivity and mRNAs are present in spinal cord neurons in locations that are associated with sensory and autonomic innervation of female reproductive organs. The present study was undertaken to examine the expression of…

Distribution and origin of corticotropin-releasing factor-immunoreactive axons in the female rat lumbosacral spinal cord.

Corticotropin-releasing factor (CRF) is a neuropeptide traditionally known for its hormonal role in the hypothalamic/pituitary/adrenal stress axis. However, CRF has been reported in axons in sites that may be considered outside of the direct stress…

Grasping primate development: Ontogeny of intrinsic hand and foot proportions in capuchin monkeys (Cebus albifrons and Sapajus apella).

Young primates have relatively large hands and feet for their body size, perhaps enhancing grasping ability. We test the hypothesis that selection for improved grasping ability is responsible for these scaling trends by examining the ontogeny of…
