Developmental Programming in Animal Models: Critical Evidence of Current Environmental Negative Changes.

The Developmental Origins of Health and Disease (DOHaD) approach answers questions surrounding the early events suffered by the mother during reproductive stages that can either partially or permanently influence the developmental programming of children, predisposing them to be either healthy or exhibit negative health outcomes in adulthood. Globally, vulnerable populations tend to present high obesity rates, including among school-age children and women of reproductive age. In addition, adults suffer from high rates of diabetes, hypertension, cardiovascular, and other metabolic diseases.

Different doses of enoxaparin in the prevention of postoperative abdominal adhesions. Experimental study.

Background: Postoperative abdominal adhesions (PAAs) are present in more than 90% of patients undergoing abdominal surgery. They are a cause of chronic pain, hospitalizations, multiple surgeries, and infertility in women of reproductive age. The participation of three processes have been recognized: coagulation, fibrinolysis, and inflammation.

Postoperative abdominal adhesions: pathogenesis and current preventive techniques.

Post-operative abdominal adhesions (PAA) are a condition that occurs in more than 90% of patients undergoing abdomen surgery; they can cause chronic abdominal pain, female infertility and repeated bowel obstruction, requiring repetitive surgical interventions causing morbidity and mortality, as well as high costs. The formation of the PAA is due to an imbalance between the fibrinogenesis and fibrinolysis in favor of the first, associated with tissue hypoxia secondary to aggression of the peritoneum, also due to the own inflammatory response and the increase in the population of adhesion fibroblasts which inhibit the degradation of the extracellular matrix and facilitate mature collagen and supporting connective tissue. The prevention of PAA will decrease secondary complications, as well as hospitalizations, surgeries and consequently, cost containment.

Multiple extrauterine pregnancy with early and near full-term mummified fetuses in a New Zealand white rabbit (Oryctolagus cuniculus).

Extrauterine pregnancy (EP) is infrequent in mammalian species and occurs when fertilized ova implant and develop outside the uterus. A common outcome is abdominal pregnancy resulting in mummified fetuses (lithopedia). Here we describe an unusual case of abdominal pregnancy with early and near full-term lithopedia.

Preliminary studies of neurosensory and cardiopulmonary health compromise in captive- bred Rhesus macaques (Macaca mulatta) suffering scoliosis.

Background: It has been widely documented that quadrupedal animals rarely display natural spontaneous scoliotic rachis deviations of the spinal column. The objective was to determine spinal deformities developed by geriatric monkeys of the Macaca mulatta species, by radiographical and tomographical studies of the vertebral column correlating morphological changes with altered physiological parameters and electrical neurosensorial conductivity of somatosensory-evoked potentials (SEPs).

Materials And Methods: A cohort of six geriatric monkeys was used: three non-scoliotic subjects and three monkeys with naturally acquired true scoliosis.

Circadian aspects of hyperthermia in mice induced by Aconitum napellus.

Background: Aconitum napellus (Acn) is used topically to relieve pain, itching and inflammation, and internally to reduce febrile states, among others. Any circadian time-related consequences of Acn administration are unknown. The objective of this study was to explore the effects of two doses of Acn on body temperature (BT) of mice treated at six different times over 24 hours.

Characterization of spontaneous subclavian steal phenomenon in a female rhesus macaque (Macaca mulatta).

In subclavian steal phenomenon (SSP), the subclavian artery develops a stenoocclusive disease proximal to the origin of the vertebral artery, leading to pronounced hemodynamic changes such as arterial flow reversal. Although SSP is a common echographic finding in humans, the phenomenon occurs only rarely in animals; consequently its physiologic features have not been reported previously. Here we describe the clinical and morphologic features of a spontaneous left SSP that was an incidental finding in an 18-y-old female rhesus macaque (Macaca mulatta).

Radiographic incidence of spinal osteopathologies in captive rhesus monkeys (Macaca mulatta).

Degenerative spinal disease is a leading cause of chronic disability both in humans and animals. Although widely seen as a normal occurrence of aging, degenerative spinal disease can be caused by various genetic, iatrogenic, inflammatory, and congenital factors. The objective of this study was to characterize the degenerative spine-related diseases and the age at onset in a random subpopulation of 20 captive rhesus monkeys (Macaca mulatta; male, 13; female, 7; age: range, 4 to 27 y; median, 18.

Somatosensory evoked potentials of median and tibial nerves in rhesus monkeys (Macaca mulatta) under captivity: influence of ontogenic status in neonatal, infant, young, adult, and senile stages.

Background: Somatosensory evoked potentials (SEPs) constitute a useful neurophysiologic tool commonly used to assess the functionality and developmental degree of the nervous system.

Objective: To analyze somatosensory pathways of the Macaca mulatta species throughout different ontogenetic statuses.

Methods: Twenty non-human primates were divided into five age-dependant groups.
