    Summary: "This book introduces a conceptual framework about the art of physical therapy to give the entry-level physical therapist assistant (PTA) student a broad foundation from which to support their journey through a typical curriculum. The purpose of this text is to cover the fundamental skills that most PTAs will use for the rest of their careers. This text provides a historical perspective on the physical therapy profession, an introduction to healthcare policy, and a definition of evidence-informed practice, and various chapters describing specific areas of clinical expertise, including how to enhance a patient's function in such tasks as bed mobility, transfers, and gait training. Chapter 1 provides a historical perspective on the physical therapy profession. Chapter 2 introduces the reader to essential healthcare policies. Chapter 3 describes the importance of evidence-informed practice and clinical decision-making. Chapter 4 outlines clinical documentation. With every patient interaction, the clinician should always ensure patient and clinician safety. Throughout the remaining chapters, the emphasis is placed on patient and clinician safety through correct body mechanics, the application of assistive and safety devices, and the effective use of infection control procedures. Chapter 5 helps prepare the clinician for patient care. Chapter 6 describes the various methods by which a clinician can take a patient's vital signs and the significance of each of these vital signs. Chapter 7 covers the various methods to perform bed mobility skills, correctly drape and position a patient. Chapter 8 teaches the reader how to perform range of motion assessments and apply range of motion techniques as a treatment method. Chapter 9 describes the various methods to accurately test the strength of each of the patient's muscles. Chapter 10 describes wheelchair mobility skills and the various methods by which the clinician or clinical team can transfer a patient from and to various surfaces. Chapter 11 details the various components and parameters of gait and how to train a patient to ambulate with or without an assistive device. Finally, chapter 12 attempts to put all of the information together by providing a patient example"-- Provided by publisher.

    The mechanism of DNA packaging into bacteriophage T4 heads in vivo was investigated by glucosylation of hydroxymethylcytosine residues in a conditionally glucose-deficient host. Cytoplasmic DNA associated with partially packaged ts49 heads can be fully glucosylated, whereas DNA already packaged into these heads is shown to be resistant to glucosylation. After temperature shift and completion of arrested packaging into the reversible temperature-sensitive ts49 head, the structure of the DNA in the mature ts49 phage was investigated by restriction enzyme digestion, autoradiography, and other techniques. Such mature DNA appears to be fully glucosylated along part of its length and nonglucosylated on the remainder. Its structure suggests that the DNA is run into the head linearly and unidirectionally from one mature end and that there is little sequence specificity in that portion of the T4 DNA which first enters the capsid. This technique should be useful in investigation of the three-dimensional structure of first- and last-packaged DNA within the head; preliminary studies including autoradiography of osmotically shocked phage suggest that the DNA which first enters the head is deposited toward the center of the capsid and that the end of the DNA which first enters the head exits first upon injection. In conjunction with studies of the structure of condensed DNA, the positions and functions of T4 capsid proteins in DNA packaging, and the order of T4 packaging functions [Earnshaw and Harrison, Nature (London) 268:598-602, 1977; Hsiao and Black, Proc. Natl. Acad. Sci. U.S.A. 74:3652-3656, 1977; Müller-Salamin et al., J. Virol. 24:121-134, 1977; Richards et al., J. Mol. Biol. 78:255-259, 1973], the features described above suggest the following model: the first DNA end is fixed to the proximal apex of the head at p20 and the DNA is then pumped into the head enzymatically by proteins (p20 + p17) which induce torsion in the DNA molecule.
