Blood-Brain Barrier: Mechanisms Governing Permeability And Interaction With Peripherally Acting Μ-Opioid Receptor Antagonists., Eugene R. Viscusi, Andrew R Viscusi

Department of Anesthesiology Faculty Papers

The blood-brain barrier (BBB) describes the unique properties of endothelial cells (ECs) that line the central nervous system (CNS) microvasculature. The BBB supports CNS homeostasis via EC-associated transport of ions, nutrients, proteins and waste products between the brain and blood. These transport mechanisms also serve as physiological barriers to pathogens, toxins and xenobiotics to prevent them from contacting neural tissue. The mechanisms that govern BBB permeability pose a challenge to drug design for CNS disorders, including pain, but can be exploited to limit the effects of a drug to the periphery, as in the design of the peripherally acting μ-opioid …

Influence Of The Menstrual Cycle On The Incidence Of Nausea And Vomiting After Laparoscopic Gynecological Surgery: A Pilot Study., Tatjana Simurina, Boris Mraovic, Neven Skitarelić, Tatjana Andabaka, Zdenko Sonicki

Department of Anesthesiology Faculty Papers

STUDY OBJECTIVE: To investigate whether the phase of menstrual cycle influences the incidence of postoperative nausea and vomiting (PONV) in women undergoing general anesthesia for elective laparoscopic gynecological surgery.

DESIGN: Prospective, observational, blinded study.

SETTING: General hospital, Postanesthesia Care Unit, and gynecologic floor room.

PATIENTS: 111 ASA physical status 1 and 2 women, aged 18 to 53 years.

INTERVENTIONS: Patients were classified into three groups according to the phase of menstrual cycle at the time of anesthesia: Group F1: follicular phase (menstrual days 1-8; n = 34); Group O2: ovulatory phase (days 9-15; n = 40); and Group L3: luteal …
