As pretreatment with intraperitoneal capsaicin (8-methyl-N-vanillyl-6-nonenamide, CAP), an agonist of the vanilloid receptor known as VR1 or transient receptor potential channel-vanilloid receptor subtype 1 (TRPV-1), has been shown to block the first phase of lipopolysaccharide (LPS) fever in rats, this phase is thought to depend on the TRPV-1-bearing(More)
Endocrine-disrupting chemicals (EDCs) are found abundantly in the environment, resulting in daily human exposure. This is of concern because many EDCs are known to target the female reproductive system and, more specifically, the ovary. In the female, the ovary is the key organ responsible for reproductive and endocrine functions. Exposure to EDCs is known(More)
In view of the potential involvement of peripherally synthesized, circulating amphipathic mediators [such as platelet-activating factor (PAF) and prostaglandin E(2)] in the systemic inflammatory response to lipopolysaccharide (LPS), we hypothesized that transport of amphipaths by albumin is essential for conveying peripheral inflammatory signals to the(More)
Obese (f/f) Koletsky rats lack the leptin receptor (LR), whereas their lean (F/?) counterparts bear a fully functional LR. By using f/f and F/? rats, we studied whether the LR is involved in lipopolysaccharide (LPS)-induced fever and hypothermia. The body temperature responses to LPS (10 or 100 microg/kg iv) were measured in Koletsky rats exposed to a(More)
Accountable care organizations (ACOs) are forming in communities across the country. In ACOs, health care providers take responsibility for a defined patient popu­lation, coordinate their care across settings, and are held jointly accountable for the quality and cost of care. This issue brief reports on results from a survey that assesses hospitals'(More)
Intraperitoneal capsaicin desensitizes sensory fibers traveling within both the vagus and splanchnic nerves. Because capsaicin desensitization blocks the first phase of lipopolysaccharide (LPS) fever, whereas surgical vagotomy does not, splanchnic mediation of the first phase was proposed. However, all phases of the febrile response of splanchnicotomized(More)
Hypothermia occurs in the most severe cases of systemic inflammation, but the mechanisms involved are poorly understood. This study evaluated whether the hypothermic response to bacterial lipopolysaccharide (LPS) is modulated by the endocannabinoid anandamide(AEA) and its receptors: cannabinoid-1 (CB1), cannabinoid-2 (CB2) and transient receptor potential(More)
Lipopolysaccharide (LPS)-induced systemic inflammation is accompanied by either hypothermia (prevails when the ambient temperature (Ta) is subneutral) or fever (prevails when Ta is neutral or higher). Because platelet-activating factor (PAF) is a proximal mediator of LPS inflammation, it should mediate both thermoregulatory responses to LPS. That PAF(More)
BACKGROUND To examine the whole postischemic hyperemic response period in Hispanic children and adults with and without type 2 diabetes mellitus (T2DM) and offer insight into the potential adaptive mechanisms involved in the arterial response to disturbances in vascular homeostasis. METHODS Ninety-eight adults and 124 children of Hispanics participated in(More)
OBJECTIVES To describe the development, implementation, and assessment of an advanced elective course on infectious diseases using active-learning strategies. DESIGN Pedagogy for active learning was incorporated by means of mini-lecture, journal club, and debate with follow-up discussion. Forty-eight students were enrolled in this 4-week elective course,(More)
