Effect of 10% Phenylephrine Eye Drops on Systemic Blood Pressure in Normotensive & Hypertensive Patients

Dynamic Effect in Capillary Pressure- Saturation Relationship and its Impact on Unsaturated Flow

Recent theories indicate that capillary pressure is perhaps not only a function of saturation but also rate of change. This is known as the dynamic effect. A comprehensive review of experiments reported in the literature is presented. The experiments provide ample evidence that a dynamic effect is observable and even q …

Effect of Material Parameters on Steady State Creep in a Thick Composite Cylinder Subjected to Internal Pressure

The steady state creep in Al- SiCP composite cylinder subjected to internal pressure was investigated. The creep behavior of the material were described by threshold stress based creep law by assuming a stress exponent of 5. The effect of size and content of the reinforcement (SiCP ), and operating temperature on the s …

Effects of Artisan aphakic intraocular lens on central corneal thickness and intra ocular pressure in pediatric eyes with crystalline subluxated lenses

Purpose: To study effects of Artisan iris fixated intraocular lens (IOL) on central corneal thickness (CCT) and intraocular pressure (IOP) in pediatric eyes with crystalline subluxated lenses. Materials and methods: The study included 17 eyes undergoing Artisan aphakic IOL implantation after lensectomy for subluxated c …

Comparison between two intravitreal injection techniques with respect to fluid reflux, intraocular pressure, and therapeutic effect

Context: Effect of fluid reflux on intraocular pressure (IOP) and therapeutic benefits. Aims: The aim of this study is to compare two intravitreal injection techniques in terms of fluid reflux, short-term IOP changes, and therapeutic effect. Settings and design: A prospective, double-blinded, randomized interventional …

Effects of head posture on intraocular pressure and heart rate of human beings

Background: The study analyzed the association of head posture on intraocular pressure (IOP). The study aimed to evaluate and measure the changes in IOP and heart rate (HR) of human beings on head-down posture. The study included 105 patients at the department of ophthalmology of a tertiary care center in India. Subjec …

Effects of Pranayam Breathing on Respiratory Pressures and Sympathovagal Balance of Patients with Chronic Airflow Limitation and in Control Subjects

Objectives: The objective of this study was to compare the effects of Pranayam breathing on respiratory muscle strength measured as maximum expiratory and inspiratory pressures (MEP and MIP) and relevant spirometry parameters in patients with chronic obstructive pulmonary disease (COPD) and in control subjects, and on …

Effect of Magnesium Supplements on Improving Glucose Control, Blood Pressure and Lipid Profile in Patients With Type 2 Diabetes Mellitus: A systematic review and meta-analysis

This study evaluated the effects of magnesium (Mg) supplementation on glycaemic control in type 2 diabetes mellitus through a meta-analysis of 23 randomised controlled trials involving 1,345 participants. Mg supplementation significantly increased serum Mg levels (weighted mean difference [WMD] = 0.69, 95% CI: 0.32 to …

A Laryngopharyngeal Mass: Pressure Effect of the Superior Cornu of the Thyroid Cartilage Induced by a Thyroid Mass

… tions. We describe a case of a patient with a medialized superior part of the thyroid cartilage caused by pressure from a large thyroid mass, detected during laryngoscopy before thyroidectomy. A neck computed tomography scan revealed an elongated and medially displaced superior cornu of the right thyroid cartilage, res …

Sick Sinus Syndrome and Cerebral Venous Thrombosis: A Connection or Coincidence? A Case Report and Literature Review

It has been hypothesized that increased intracranial pressure (ICP) may cause sick sinus syndrome (SSS) due to its effect on vagal discharge to the heart, resulting in disruption to the sinus cycle, despite age-related degeneration of the sinoatrial node being the most common intrinsic factor leading to sinus node dysf …

CFD Simulation of Sohar Ambient Temperature Variation Effects on the Performance of a Wind Tunnel with a Fixed-Blade Wind Accelerator

… arid and semi-arid regions such as Sohar. The present study shows a computational investigation into the effects of temperature variations on the performance of a wind tunnel integrated with a fixed-blade wind accelerator, using climatical conditions of Sohar. The Computational Fluid Dynamics (CFD) simulations were pe …
