Fibronectin Study guides, Class notes & Summaries

Ms. Linghu arrived at the obstetric care unit for a labor evaluation. She is 28 weeks gestation and is complaining of a lower back ache and cramping. The physician has asked for assistance in obtaining a sample to assess for fetal fibronectin (fFN). Which statement about fFN is most accurate? - fFN is a strong predictor or marker for identification of preterm labor associated with infection. Risk factors for placenta previa include - previous uterine surgery, smoking, and hypertension. One ...

Understanding Pathophysiology 7th Edition Test Bank Chapter 1. Cellular Biology MULTIPLE CHOICE 1. A student is observing a cell under the microscope. It is observed to have supercoiled DNA with histones. Which of the following would also be observed by the student? a. A single circular chromosome b. A nucleus c. Free-floating nuclear material d. No organelles ANS: B The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA within its nucleus; thus,...

(immobilization) without normal stresses, - ligaments and bones become weaker as well 1 MHz setting vs. 3 MHz setting of US - 1 MHZ is for deeper tissue 3 MHz is for more superficial tissue 2 essential elements in improving neuromuscular control - proprioception and kinesthesis 2 types of low-lever lasers - helium neon (HeNe) gallium arsenide (GaAs) 3 components of female athlete triad - disordered eating, amenorrhea, osteoporosis 3 phases of the healing process - inflammatory phase fibr...

1. A patient who is G3P2 at 32 weeks' gestation arrives at the triage unit complaining of regular uterine contractions. Her pregnancy history includes a preterm delivery at 34 weeks. Before examining her, the nurse performs electronic fetal monitoring and obtains a complete history. The patient reports no bleeding and no rupture of membranes. She has no vaginal examinations or sexual activity for more than 24 hours. The biochemical marker useful in this situation for predicting pret...

Campbell Biology Exam Questions with Correct Answers Collagen - Answer-structural protein found in the skin and connective tissue - most abundant in animals Proteoglycans - Answer-a glycoprotein consisting of a small core protein with many carbohydrate chains attached, found in the extracellular matrix of animal cells. Fibronectin - Answer-An extracellular glycoprotein secreted by animal cells that helps them attach to the extracellular matrix. Exocytosis - Answer-Process by which a ce...

Which cells located in the dermis produce collagen (dermal building blocks) and elastin (tensile strength)? Select one: a. Leukotrienes. b. Mast cells. c. Macrophages. d. Fibroblasts. - answer-d. Fibroblasts. Fibroblasts' main function is to make connective tissue and the extracellular matrix, specifically the production of collagen (dermal building blocks) and elastin (tensile strength) and fibronectin, which binds extracellular matrix proteins. A patient has an acute full-thickness ...

NURS 223 Medical-Surgical Nursing EXAM 2 The student nurse learning about cellular regulation understands that which process occurs during the S phase of the cell cycle? a. Actual division (mitosis) b. Doubling of DNA c. Growing extra membrane d. No reproductive activity ANS: B During the S phase, the cell must double its DNA content through DNA synthesis. Actual division, or mitosis, occurs during the M phase. Growing extra membrane occurs in the G1 phase. During the G0 phase, the ce...
