A local effect of endogenous ovarian hormones on the
in vitro responses of the bovine infundibulum to the
neurotransmitters norepinephrine (NE) and acetylcholine
(Ach) was investigated. Prostaglandin F₂α-tham salt was
utilized to induce luteal regression in six heifers
which were necropsied during proestrus. Six heifers were
also necropsied during the...
There are between one and two million
occurrences of head injuries in this country each
year causing an estimated 140,000 deaths. Fifty to
seventy thousand who survive are left with such
intellectual impairment as to preclude returning to a
normal life. The purpose of this study is to
investigate the...
The ionotropic glutamate receptors are ligand-gated ion channels that mediate the majority of excitatory neurotransmission in the brain. The three classes of ionotropic glutamate receptors are alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA), N-methyl-D-aspartate (NMDA), and kainite. These three classes have unique subunits. NMDA receptors play important roles in development, forms of synaptic plasticity,...
The psychoactive component of marijuana, A9-tetrahydrocannabinol (THC), is known
to have effects in humans that are mediated by the cannabinoid receptor (CB 1). Although a great deal of research has been done to confirm the interaction of exogenous cannabinoids with the CB 1 receptor, little is known about the receptor's...
Traumatic brain injury (TBI) is a leading cause of death and disability in the United States. However, along with the increase in the occurrence of TBI, there has been a drastic decrease in the acute and long-term care provided for the TBI patient. This study provides information on the short-...
BACKGROUND: Occupational exposure to extremely low frequency magnetic fields (ELF) is a
suspected risk factor for brain tumours, however the literature is inconsistent. Few studies have
assessed whether ELF in different time windows of exposure may be associated with specific
histologic types of brain tumours. This study examines the association...
From merely being cod liver oil taken for vitamins A and D, fish oils have moved into the center stage of fatty acids in nutrition. The analytical work starting in 1950 provided the means to recognize the long-chain and truly essential n-3 polyunsaturated fatty acids vital for retinal, neurological and...
Traumatic brain injury (TBI) is a significant public health issue due to the incidence,
complexity, and cost associated with treatment. The purpose of this study was to
determine physical activity (PA) knowledge, attitudes, intentions, and barriers
among individuals with a TBI undergoing outpatient rehabilitation. Seventeen
participants completed a series of...
BACKGROUND: Zebrafish have been used as a vertebrate model to study human cancers such as melanoma,
rhabdomyosarcoma, liver cancer, and leukemia as well as for high-throughput screening of small molecules of
therapeutic value. However, they are just emerging as a model for human brain tumors, which are among the most...
