A Short History Of Uranium, Fathi Habashi Jul 2015

A Short History Of Uranium, Fathi Habashi

Fathi Habashi

Uranium was discovered in 1781 by Klaproth, a pharmacist in Berlin, from the black mineral pitchblende found in Joachimsthal silver mines. Peligot in France in 1841 proved that what Klaproth isolated from pichblende was uranium oxide and not the metal. Uranium salts were used at that time to manufacture coloured glass before the discovery of its radioactivity in 1896. It became in great demand when its decay product radium was found to cure cancer. The discovery if uranium fission in 1939 was the reason for the manufacture of the first atomic bomb.

Paracetamol and piroxicam are non-steroidal anti-inflammatory drugs (NSAIDs), widely used in pain and inflammatory diseases. The present study aimed to evaluate the impact of biofield treatment on spectral properties of paracetamol and piroxicam. The study was performed in two groups (control and treatment) of each drug. The control groups remained as untreated, and biofield treatment was given to treatment groups. Subsequently, spectral properties of both drugs before and after biofield treatment were characterized using FT-IR and UV-Vis spectroscopic techniques. FT-IR data of paracetamol showed N-H amide II bending peak in biofield treated paracetamol, which was shifted to lower wavenumber (1565 …

OBJECTIVE: To assess the value of extended volume irradiation with anastomotic coverage in high risk resected esophageal cancer patients. METHOD: A retrospective study was undertaken at LRCC from 1989-1999 for high risk resected esophageal cancer patients. Adjuvant treatments consisted of 4 cycles of chemotherapy (epirubicin/fluorouracil/cisplatin or cisplatin/fluorouracil), and local regional irradiation with or without coverage of the anastomotic site. Radiation dose ranged from 45-60Gy at 1.8-2.0 Gy/fraction given with initial anterior-posterior/posterior-anterior arrangement with either extended (with anastomotic coverage) or small (without anastomotic coverage) field followed by oblique fields for boost. RESULT: One hundred eighty-eight charts were reviewed. Seventy-two patients were …

The Impact Of Spinal Cord Nerve Roots And Denticulate Ligaments On Cerebrospinal Fluid Dynamics In The Cervical Spine, Soroush Heidari Paylavian, Theresia Yiallourou, R. Shane Tubbs, Alexander C. Bunck, Francis Loth, Bryn A. Martin, Mark Goodin, Mehrdad Raisee

Dr. Francis Loth

Cerebrospinal fluid (CSF) dynamics in the spinal subarachnoid space (SSS) have been thought to play an important pathophysiological role in syringomyelia, Chiari I malformation (CM), and a role in intrathecal drug delivery. Yet, the impact that fine anatomical structures, including nerve roots and denticulate ligaments (NRDL), have on SSS CSF dynamics is not clear. In the present study we assessed the impact of NRDL on CSF dynamics in the cervical SSS. The 3D geometry of the cervical SSS was reconstructed based on manual segmentation of MRI images of a healthy volunteer and a patient with CM. Idealized NRDL were designed …

Segmentation Of Pulmonary Nodules In Computed Tomography Using A Regression Neural Network Approach And Its Application To The Lung Image Database Consortium And Image Database Resource Initiative Dataset, Temesguen Messay, Russell C. Hardie, Timothy R. Tuinstra Mar 2015

Segmentation Of Pulmonary Nodules In Computed Tomography Using A Regression Neural Network Approach And Its Application To The Lung Image Database Consortium And Image Database Resource Initiative Dataset, Temesguen Messay, Russell C. Hardie, Timothy R. Tuinstra

Russell C. Hardie

We present new pulmonary nodule segmentation algorithms for computed tomography (CT). These include a fully-automated (FA) system, a semi-automated (SA) system, and a hybrid system. Like most traditional systems, the new FA system requires only a single user-supplied cue point. On the other hand, the SA system represents a new algorithm class requiring 8 user-supplied control points. This does increase the burden on the user, but we show that the resulting system is highly robust and can handle a variety of challenging cases. The proposed hybrid system starts with the FA system. If improved segmentation results are needed, the SA …

Elastic, Viscous, And Mass Load Effects On Poststroke Muscle Recruitment And Co-Contraction During Reaching: A Pilot Study, Tina M. Stoeckmann, Katherine J. Sullivan, Robert A. Scheidt

Robert Scheidt

Background: Resistive exercise after stroke can improve strength (force-generating capacity) without increasing spasticity (velocity-dependent hypertonicity). However, the effect of resistive load type on muscle activation and co-contraction after stroke is not clear. Objective: The purpose of this study was to determine the effect of load type (elastic, viscous, or mass) on muscle activation and co-contraction during resisted forward reaching in the paretic and nonparetic arms after stroke. Design: This investigation was a single-session, mixed repeated-measures pilot study. Methods: Twenty participants (10 with hemiplegia and 10 without neurologic involvement) reached forward with each arm against equivalent elastic, viscous, and mass loads. …

Potential Dual Imaging Nanoparticle: Gd2o3 Nanoparticle, Md Wasi Ahmad Jan 2015

Potential Dual Imaging Nanoparticle: Gd2o3 Nanoparticle, Md Wasi Ahmad

Dr. Mohammad Wasi Ahmad (Md Wasi Ahmad)

Gadolinium (Gd) is a unique and powerful element in chemistry and biomedicine which can be applied simultaneously to magnetic resonance imaging (MRI), X-ray computed tomography (CT), and neutron capture therapy for cancers. This multifunctionality can be maximized using gadolinium oxide (Gd2O3) nanoparticles (GNPs) because of the large amount of Gd per GNP, making both diagnosis and therapy (i.e., theragnosis) for cancers possible using only GNPs. In this study, the T1 MRI and CT dual imaging capability of GNPs is explored by synthesizing various iodine compound (IC) coated GNPs (IC-GNPs). All the IC-GNP samples showed stronger X-ray absorption and larger longitudinal …

Exhibition Handlist, Kathleen M. Webb Jan 2015

Exhibition Handlist, Kathleen M. Webb

Kathleen M. Webb

In preparing for Imprints and Impressions, we ran across many interesting words that have fallen out of the general lexicon. With this booklet, we have brought one back: handlist. Dean Kathleen Webb ran across it in a 1944 booklet from the J. Pierpont Morgan Library in New York City. Though the word no longer appears in most new dictionaries, it’s still in the Oxford English Dictionary: A list of a particular type or category of things, presented in a readily consultable form; esp. a list of the books or manuscripts in a particular place, on a particular subject, etc.; a …

Real-Time Mri-Guided Catheter Tracking Using Hyperpolarized Silicon Particles, Nicholas Whiting, Jingzhe Hu, Jay V. Shah, Maja C. Cassidy, Erik Cressman, Niki Zacharias Millward, David G. Menter, Charles M. Marcus, Pratip K. Bhattacharya

Nicholas Whiting

Visualizing the movement of angiocatheters during endovascular interventions is typically accomplished using x-ray fluoroscopy. There are many potential advantages to developing magnetic resonance imaging-based approaches that will allow three-dimensional imaging of the tissue/vasculature interface while monitoring other physiologically-relevant criteria, without exposing the patient or clinician team to ionizing radiation. Here we introduce a proof-of-concept development of a magnetic resonance imaging-guided catheter tracking method that utilizes hyperpolarized silicon particles. The increased signal of the silicon particles is generated via low-temperature, solid-state dynamic nuclear polarization, and the particles retain their enhanced signal for ≥40 minutes—allowing imaging experiments over extended time durations. The …


Flow Of Dna Solutions In A Microfluidic Gradual Contraction, Shelly Gulati, Susan J. Muller, Dorian Liepmann Jan 2015

Flow Of Dna Solutions In A Microfluidic Gradual Contraction, Shelly Gulati, Susan J. Muller, Dorian Liepmann

Shelly Gulati

The flow of λ-DNA solutions in a gradual micro-contraction was investigated using direct measurement techniques. The effects on DNA transport in microscale flows are significant because the flow behavior is influenced by macromolecular conformations, both viscous and elastic forces dominate inertial forces at this length scale, and the fully extended length of the molecule approaches the characteristic channel length wc (L/wc ∼ 0.13). This study examines the flow of semi-dilute and entangled DNA solutions in a gradual planar micro-contraction for low Reynolds numbers (3.7 × 10−6 < Re < 3.1 × 10−1) and high Weissenberg numbers (0.4 < Wi < …
