At the time of parturition (fetal delivery) the uterine cervix must "ripen," becoming soft, pliable, and dilated to accommodate the fetus' delivery. The fundamental processes underlying cervical ripening remain poorly understood. Knowledge that…
We combined retrograde tracing with immunohistochemistry for choline acetyltransferase to identify the source of cholinergic input to the inferior colliculus (IC) in guinea pigs. Injection of a retrograde tracer into one IC labeled cells in many…
INTRODUCTION: Spreading pigmented actinic keratosis (SPAK) is a common, but uncommonly reported or appreciated, variant of classic actinic keratosis (AK). It can mimic different pigmented lesions, which may be benign (eg, solar lentigo) or malignant…
Prior to parturition the non-pliable uterine cervix undergoes a ripening process ("softens" and dilates) to allow a timely passage of the fetus at term. The exact mechanism(s) triggering and involved in cervical ripening are unknown, though evidence…
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…
The vascular supply and tendons of the extensor digitorum longus (EDL) muscles of two adult rats were unilaterally severed and the muscles were allowed to regenerate for 40 days. Serial frozen sections of muscle grafts were cut and stained for…
Trianthema portulacastrum, a medicinal and dietary plant, has gained substantial importance due to its various pharmacological properties, including anti-inflammatory and anticarcinogenic activities. We have recently reported that a characterized T.…
The endocardium ultrastructure of 13 embryonic day old hamsters was examined, especially in relationship with the atrial myocytes. The endothelial morphology was described, including the junctional attachments and their relationships with subjacent…
Previous anatomical studies demonstrated vagal innervation to the ovary and distal colon and suggested the vagus nerve has uterine inputs. Recent behavioral and physiological evidence indicated that the vagus nerves conduct sensory information from…
