Impedance Rhythms in Human Limbic System.

The impedance is a fundamental electrical property of brain tissue, playing a crucial role in shaping the characteristics of local field potentials, the extent of ephaptic coupling, and the volume of tissue activated by externally applied electrical brain stimulation. We tracked brain impedance, sleep-wake behavioral state, and epileptiform activity in five people with epilepsy living in their natural environment using an investigational device. The study identified impedance oscillations that span hours to weeks in the amygdala, hippocampus, and anterior nucleus thalamus.

Pharmacist Intervention Lowers HgbA1c in Diabetic Patients Regardless of HIV Status.

Aim: Compare glycemic control in human immunodeficiency (HIV)-positive patients on antiretroviral therapy to HIV-negative patients following pharmacist interventions.

Methods/results: This retrospective observational cohort study conducted at a Federally Qualified Health Center included adults with type II diabetes mellitus who attended at least two clinical pharmacy appointments between January 1, 2018 and July 31, 2019. Exclusion criteria included missing pre- or post-hemoglobin A1c (HgbA1c) values, type 1 diabetes, pregnancy, breastfeeding, deceased, or untreated HIV.

Computed Tomography Cholangiography Using the Magnetic Resonance Contrast Agent Gadoxetate Disodium: A Phantom Study.

Objective: The purpose of this work is to determine whether low doses of gadoxetate disodium (Eovist; Bayer Healthcare LLC, Whippany, NJ), a gadolinium-based contrast agent used for magnetic resonance liver imaging, can be visualized for computed tomography (CT) cholangiography using a phantom setup.

Materials And Methods: Vials containing 4 concentrations of gadoxetate disodium (1.9, 3.

Making choices impairs subsequent self-control: a limited-resource account of decision making, self-regulation, and active initiative.

The current research tested the hypothesis that making many choices impairs subsequent self-control. Drawing from a limited-resource model of self-regulation and executive function, the authors hypothesized that decision making depletes the same resource used for self-control and active responding. In 4 laboratory studies, some participants made choices among consumer goods or college course options, whereas others thought about the same options without making choices.
