BACKGROUND Child screen viewing (SV) is positively associated with poor health indicators. Interventions addressing rule-based parenting practices may offer an effective means of limiting SV. This study examined associations between rule-based parenting practices (limit and collaborative rule setting) and SV in 6-8-year old children. METHODS An online survey of 735 mothers in 2011 assessed: t...

A 56-year-old male patient was admitted for catheter ablation of highly symptomatic paroxysmal atrial fibrillation. During the procedure, a rare anatomic variation with an interrupted inferior caval vein (ICV) branching suprarenal into an azygos venous continuation draining into the superior caval vein was detected. Using angiography, a continuation of the ICV leading into the liver, subdividin...

To elucidate the control of hepatic cholesterol metabolism by leptin, rats were administered IV (intravenous) leptin, ICV (intracerebroventricular) leptin or saline. A single low dose of ICV leptin was as effective as a continuous IV infusion of high-dose leptin at decreasing the activities of 3-hydroxy-3-methylglutaryl-CoA reductase and cholesterol 7alpha-hydroxylase. These results indicate th...

Angiotensin II (ATII) causes through the central nervous mechanism certain cardiovascular disorders. Th e participation of a central nervous component in the genesis of cardiac arrhythmia caused by Angiotensin is stated. Th e present paper describes the action exerted by ATII on the cardiac rhythm, after intracerebroventricular administration (icv) in rats anesthetized with ethylic urethane. Th...

The purpose of this article is to compare the visualization quality of ICV and their tributaries on PSI-MRV, 3D CE-MRV, and 3D CE-FSPGR. PSI-MRV has been shown to delineate the ICV, TSV, SV, anterior caudate nucleus veins, and medial atrial veins effectively. Due to its advantages of no contrast material injection, acceptable examination times, and no arterial contamination, PSI-MRV should be c...

intracerebroventricular (icv) injection of streptozotocin (stz) in rats is followed by long-term and progressive deficits in learning, memory, and cognitive performance which is somewhat similar to sporadic alzheimer’s disease (sad). epidemiological studies suggest that non-steroidal anti-inflammatory drugs (nsaids) could delay or slow the clinical expression of sad. therefore, the beneficial e...

INTRODUCTION Dimethyl sulfoxide (DMSO) is a chemical often used as a solvent for water-insoluble drugs. In this study, we evaluated the effect of intracerebroventricular (ICV) administration of DMSO on neural response characteristics (in 1200-1500 μm depth) of the rat barrel cortex. METHODS DMSO solution was prepared in 10% v/v concentration and injected into the lateral ventricle of rats. Ne...

(2017): Effect of opioid receptors agonists on feeding behaviour using different diets in ad libitum fed neonatal chicken. Czech J. Anim. Sci., 62, 98–109. Despite progress in studying the role of opioids in reward, the effect of opioid receptors on feeding behaviour in ad libitum fed meat-type chi...

The effect of intracerebroventricular (ICV) antileptin antibody on the onset of puberty in the female rat and the relationship between serum leptin, luteinizing hormone (LH), and body weight were investigated. Antileptin antibody (group A) was infused ICV from days 23-36 in prepubertal female rats whereas the control (group B) received ICV goat immunoglobulin G (IgG). In the antileptin group, m...
