Surgical clipping of paraclinoid aneurysms involving the anterior clinoid process (ACP) can present great challenges because strong adhesion may hinder dissection of the surrounding anatomical structures from the aneurysm dome. On the other hand, retrograde suction decompression (RSD) through direct puncture of the common carotid artery is a useful adjunct technique for clipping of these aneurysms. The present case illustrates that direct clipping of paraclinoid aneurysms involving the ACP can be achieved safely and less invasively using RSD during anterior clinoidectomy...

Despite the widespread acceptance of rotary blood pump (RBP) in clinical use over the past decades, the diminished flow pulsatility generated by a fixed speed RBP has been regarded as a potential factor that may lead to adverse events such as vasculature stiffening and hemorrhagic strokes. In this study, we investigate the feasibility of generating physiological pulse pressure in the pulmonary circulation by modulating the speed of a right ventricular assist device (RVAD) in a mock circulation loop. A rectangular pulse profile with predetermined pulse width has been implemented as the pump speed pattern with two different phase shifts (0% and 50%) with respect to the ventricular contraction...

INTRODUCTION: Mesenchymal stem cells are already used in numerous areas of medicine. In the field of plastic surgery, the main focus of recent research has been to utilise adipose-derived stromal cells (ASCs), mainly harvested via liposuction. The ability to release regenerative cytokines is supposed to be the key mechanism for the therapeutic efficacy of ASCs. There are currently a variety of methods and devices in clinical use for harvesting lipoaspirate and consequently ASCs. For most of these devices, the effect on the regenerative cytokine profile of ASCs is unknown...

Over the last 20 years, 640 premature newborns with alterations in suction-deglution have been taken care of in the neonatal intensive care unit at the Hospital Infantil de México Federico Gómez, using techniques for patients with immaturity, and neurological, gastrointestinal, cardiologic and respiratory pathologies. This descriptive study includes the treatment employed mainly in premature newborns during this period. Suction, swallowing and breathing coordination are some of the most complex abilities that premature newborns face, due to their anatomofunctional immaturity and improper sensoriomotor integration for the high energy requirements they must meet...

OBJECTIVE: Despite the absence of "evidence-based medicine", the use of closed suction drainage in breast surgery is currently the standard practice. Its goal is to minimize the amount of fluid at the operation site, the dead space that can involve postoperative complications. The purpose of this study is to demonstrate that with or without drainage the complication rate is unchanged. METHODS: We conducted a retrospective and comparative study of two groups of breast reduction with and without drainage...

Chenglei Wang, Hui Tang
In this study, we explore the use of synthetic jet (SJ) in manipulating the vortices around a rigid heaving airfoil, so as to enhance its aerodynamic performance. The airfoil heaves at two fixed pitching angles, with the Strouhal number, reduced frequency and Reynolds number chosen as St=0.3, k=0.25 and Re=100, respectively, all falling in the ranges for natural flyers. As such, the vortex force plays a dominant role in determining the airfoil's aerodynamic performance. A pair of in-phase SJs is implemented on the airfoil's upper and lower surfaces, operating with the same strength but in opposite directions...

Haemophilia is an inherited bleeding disorder with variable deficiency of Factor VIII in the plasma and is characterised by bleeding into joints, muscles and tissues either spontaneously or in response to trivial trauma. Perioperative care requires multidisciplinary involvement. Perioperative management involves the risk of excessive bleeding from surgical site as well as spontaneous bleeding into the brain in response to surgical stress in patients with previous history of intracerebral haemorrhage. Airway management of such patients during anaesthetic intervention is a challenge and entails the risk of life threatening haemorrhage into the airway...
