In this 75th year of Mallinckrodt Institute's existence, the first of a three-part series of articles will chronicle the rapid advancement of radiol- ogy at Washington University and the emergence of MIR as a world leader in the field of radiology. THE METABOLISM OF THE DIABETIC HEART More diabetic patients die from cardiovascular disease than from any other cause. Researchers in the Institute's Cardiovascular Imaging Laboratory are finding that the heart's metabolism may be one of the primary mechanisms by which diseases such as diabetes have a detrimental effect on heart function.

Electroretinography 1 Electroretinography
Electroretinography 1 Electroretinography Electroretinography measures the electrical responses of various cell types in the retina, including the photoreceptors (rods and cones), inner retinal cells (bipolar and amacrine cells), and the ganglion cells. Electrodes are usually placed on the cornea and the skin near the eye, although it is possible to record the ERG from skin electrodes. During a recording, the patient's eyes are exposed to standardized stimuli and the resulting signal is displayed showing the time course of the signal's Maximal response ERG waveform from a dark adapted eye. amplitude (voltage). Signals are very small, and typically are measured in microvolts or nanovolts. The ERG is composed of electrical potentials contributed by different cell types within the retina, and the stimulus conditions (flash or pattern stimulus, whether a background light is present, and the colors of the stimulus and background) can elicit stronger response from certain components. If a flash ERG is performed on a dark-adapted eye, the response is primarily from the rod system and flash ERGs performed on a light adapted eye will reflect the activity of the cone system. To sufficiently bright flashes, the ERG will contain an A patient undergoing an electroretinogram a-wave (initial negative deflection) followed by a b-wave (positive deflection). The leading edge of the a-wave is produced by the photoreceptors, while the remainder of the wave is produced by a mixture of cells including photoreceptors, bipolar, amacrine, and Muller cells or Muller glia.[1] The pattern ERG, evoked by an alternating checkerboard stimulus, primarily reflects activity of retinal ganglion cells. -

Methods: A total of 20 infertile women admitted to our hospital from October 2018 to December 2019 were selected as the subjects of study for retrospective analysis. The MR-HSG examination was performed in all patients to analyze the examination results and imaging characteristics. Results: (1) The comple- tion rate of MR-HSG examination was 100.00% in the 20 patients, of which those with primary infertility accounted for 65.00% and those with secondary infertility accounted for 35.00%. (2) Among the 20 infertile patients, 30.00% had unobstructed fallopian tubes, 40.00% had partial fallopian tube obstruction, 20.00% had full fallopian tube obstruction and 10.00% had hydrosalpinx. (3) Among the 14 patients with abnormal fallopian tubes, 14.29% had bilateral fallopian tube obstruction, 35.71% had partial fallopian tube obstruction on both sides, 7.14% had fallo- pian tubes that were unobstructed on one side and obstructed on the other side, 21.43% had fallopian tubes that were unobstructed on one side and partially obstructed on the other side, 7.14% had fallopian tubes partially ob- structed on one side and obstructed on the other side, and 14.29% had hydrosalpinx. -

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract Duplication of gall bladder is a rare congenital anomaly of the hepatobiliary system. It is a very important entity in clinical practice as preoperative diagnosis plays a significant role in the man- agement and to avoid unnecessary bile duct injury during surgery. We report a case of duplicated gall bladder presenting as acute cholecystitis. Keywords Gall Bladder, Duplication, Cholecystitis 1. Introduction Gall bladder (GB) duplication is a rare congenital anomaly of hepatobiliary system with a reported incidence of about 1 per 4000 autopsies [1]. Duplication of gall bladder and their varying anatomical positions are associated with an increased risk of complications including biliary leak after laparoscopic or open cholecystectomy [2]-[5]. 2. Case Presentation A 45 years old lady presented with complaints of abdomen pain for the past two days. It was colicky type pain, intermittent in nature and localized to the right hypochondrium. She also gave history of three episodes of vo- miting which was non bilious, non blood stained and non foul smelling. -
