(2017-04-24)Thyroid hormones regulate essential physiological processes, including metabolism, reproduction, and growth. A key constituent of all thyroid hormones is iodine. To obtain and concentrate iodine, vertebrates utilize a ...
-
Endospore formation by Clostridium difficile is a vital part of the life cycle for this Gram-positive bacterium. During this process, the mothercell packages proteins into the developing endospore. However, the mechanisms ...
-
(1977)The purpose of this study was to investigate the cell-mediated activity of the facultative intracellular parasite, Listeria Monocytogenes, in the guinea pig. Special emphasis was placed upon the particular subcellular ...
-
(2014-09-08)Important neurological and psychiatric diseases, including Alzheimer disease, nicotine addiction, and schizophrenia, are influenced by nicotinic acetylcholine receptors (nAChRs). Understanding the structure and function ...
-
(1993)Protein extracts from Anabaena sp. strain PCC 7120 contain the site-specific DNA-binding proteins BifA and BifB. The bifA gene was recently cloned in our laboratory using a transcriptional interference strategy. When applied ...
-
Male Caenorhabditis elegans undergo a radical remodeling of their anal depressor during late larval stage 4. In both hermaphrodites and males, the larval anal depressor primarily functions as a defecation behavior. However, ...
-
(2012-04-23)Paramecium tetraurelia is a large, single-celled, ciliated protist. Short cell cycle times (4.5-5 hours) and manipulable Mendelian genetics have made it an attractive research species, particularly for developmental genetics ...
-
Electron beam (eBeam) technology is commonly used to sterilize food and food ingredients to inactivate microbial pathogens. In eBeam processing, electrons are accelerated to the speed of light in a linear accelerator, ...
-
(2013-02-06)The flagella organelle is crucial to many different cells and organisms because it allows for sensation and movement throughout a matrix. The Intraflagellar Transport system (IFT) is of particular interest since it helps ...
-
(2013-09-24)Anemia is a term that defines a condition in which a person’s blood lacks a stable amount of red blood cells or hemoglobin. This condition can cause a person to experience fatigue, and an improper amount of oxygen will be ...
-
(1997)What are the cellular mechanisms that govern when the outgrowing neurite of a neuron will branch? This research analyzed one possible biochemical pathway through which environmental and cellular signals are transduced into ...
-
(2014-10-14)Cancer is a group of diseases characterized by uncontrolled cell proliferation. Cancer is responsible for nearly 1 of every 4 deaths, and ranks as the second highest cause of death worldwide, and costs the American population ...
-
(2012-05-04)The bacterial spirochete Borrelia burgdorferi, the causative agent of Lyme disease (LD) encodes for the von Willebrand Factor A (VWFA) domain proteins BB0172 and BB0173. VWFA domains are commonly known for adhering to ...
-
(2018-04-23)Clostridioides difficile is a Gram-positive, anaerobic, spore-forming pathogen. Due to, in part, the highly transmissible spore morphotype, C. difficile infections (CDI) frequently occur in cycles of recurring disease that ...
-
Characterization of Fluffy A. nidulans Mutants Induced by 5-Azacytidine and 4-Nitroquinoline-1-Oxide (1991)The manner in which the fluF mutation was isolated makes it very interesting because it suggests that it may arise from an epigenetic defect. 5-Azacytidine (5-AC) treatment results in a high frequency of conversion of wild ...
-
(2013-02-04)Cellular movement in response to a chemical gradient, known as chemotaxis, is a critical behavior in many developmental and pathological processes such as embryo development and cancer metastasis. This cell movement can ...
-
(2011-08-08)Shwachman Diamond syndrome is an autosomal recessive disease associated with pancreatic insufficiency, skeletal abnormalities, and bone marrow failure. The de Figueiredo lab has recently shown physical and genetic interactions ...
-
(2019-04-22)Each year, hundreds of thousands of Americans are affected by surgical site infections (SSIs), resulting in billions of dollars spent on additional healthcare and thousands of lives lost. These SSIs are often caused by ...
-
Paramecium tetraurelia are single celled protists commonly found in freshwater. Each paramecium cell is covered by 3,000 cilia, organized into about 70 precise longitudinal rows. Rows can be inverted 180 degrees through a ...
-
The genus Thraulodes (Ephemeroptera: Leptophlebiidae) is widely distributed across the Americas, and can be found in lotic systems throughout North, Central, and South America (Chacón et. al, 1999). With 45 described ...
