Cerebral hypercapnia-induced vasomotor reactivity in migraine with and without aura: a case-control study

 Abstract Background: Dysfunction of the autonomic nervous system has long been a subject of considerable debate and a large number of studies have disclosed contradictory results. The aim of this study was to compare cerebral vasomotor reactivity in migraine with aura (MWA) patients with migraine without aura (MWO) ones. Methods: Ten MWA patients (7 females and 3 males mean age: 39.70 years, S...

Influence of Seismic Pounding on RC Buildings with and without Base Isolation System Subject to Near-Fault Ground Motions

Building pounding occurs between two adjacent buildings with small gap or without sufficient separation distance. It leads to damage buildings during earthquake due to impact. Many researchers have investigated building pounding based on impact force reduction and energy dissipation increase, when two buildings collide with each other. In numerical investigations, using specific link element, i...

Second Order Sliding Mode Observer-Based Control for Uncertain Nonlinear MEMS Optical Switch

This paper studies theuncertain nonlinear dynamics of a MEMS optical switch addressing electrical, mechanical and optical subsystems. Recently, MEMS optical switch has had significant merits in reliability, control voltage requirements and power consumption. However, an inherent weakness in designing control for such systems is unavailability of switch position information at all times due to t...

Relationship of Interleukin-4 and Interleukin-6 with Pigmentation Disorders in Sardasht Sulfur Mustard-Exposed Veterans 20 Years after Exposure

Aims: Pigmentation disorders are one of the main skin problems due to mustard gas exposure in chemically-injured veterans. The aim of this study as part of the Sardasht cohort study was to investigate the association between IL-6 and IL-4 and pigment disorders in chemically-injured veterans exposed to mustard gas. Materials & Methods: In this study, 500 subjects including 372 people expose...

Evaluation of L- Fucose and SialicAcid Levels in Patients with ColorectalCancer and Control Subject

مقایسه‌ی حقوق بیماران در تحقیقات پزشکی در جهان

Immoral actions in medical research in past has increased that sensitivity to this subject. A review on international laws shows that sometimes these researches has violated ethics and has examined people without to tell them about the experiments. The Nuremberg law was made for to trial Nazi's Medicines in 1947 that had been experienced people without they know about the tests. According to th...
