The goal of this study was to determine the effects of microgravity on myofilament protein expression and both passive and active length-force relationships in carotid and femoral arteries. Microgravity was simulated by 20-day hindlimb unweighting (HU) in Wistar male rats, and carotid and femoral artery segments were isolated from both HU and control (CTL) rats for Western blot and length-force...

OBJECTIVE To evaluate progressive enhancement in the carotid arterial wall overlying plaque in the symptomatic side for patients with cerebrovascular symptoms until delayed phase using MDCTA. MATERIALS AND METHODS Twenty-one patients (all men; ages, 49-82 years; mean, 67.8 ± 8.4 years) with recent stroke and severe extracranial carotid stenosis were retrospectively analyzed. Pre-, early- and ...

Hydroxyurea (HU) is commonly used to treat myeloproliferative diseases and sickle cell anemia. The administration of HU to gestation day 9 CD1 mice causes predominantly hindlimb, tail, and neural tube defects. HU induces oxidative stress and p38 mitogen-activated protein kinase (MAPK) signaling in embryos. HU also inactivates ribonucleotide reductase, leading to DNA replication stress and DNA d...

Introduction: Cortical thickness, interradicular space width and bone density are key factors in the use of mini-implants as anchorage. Objective: This study assessed maxillary and mandibular alveolar and basal bone density in Hounsfield units (HU). Method: Eleven files with CT images of adults were used to obtain 660 measurements of bone density: alveolar (buccal and lingual cortical) bone, ca...

Unloading-induced muscle atrophy occurs in the aging population, bed-ridden patients, and astronauts. This study was designed to determine whether dynamic foot stimulation (DFS) applied to the plantar surface of the rat foot can serve as a countermeasure to soleus muscle atrophy normally observed in hindlimb unloaded (HU) rats. Forty-four mature (6 mo old), male Wistar rats were randomly assign...

BACKGROUND Hydroxyurea (HU) is the only disease-modifying medication for patients with sickle cell disease (SCD). HU can reduce SCD-related complications but only 35% to 50% of pediatric patients adhere to HU at the rates achieved in clinical trials and this limits its clinical effectiveness. Mobile Directly Observed Therapy (Mobile DOT) is a pilot-tested, electronic, multidimensional, HU adher...
