Within recent years, the field of nano-mechanics has diversified in a variety applications, ranging from quantum information processing to biological molecules recognition. Among diversity devices produced these days, simplest (but versatile) element remains doubly-clamped beam: it can store very large tensile stresses (producing high resonance frequencies $f_0$ and quality factors $Q$), is int...

BACKGROUND AND PURPOSE A potential source of complication at carotid endarterectomy (CEA) is cerebral ischemia caused by hypoperfusion during clamping of the carotid artery. Configuration of primary collateral pathways may be a major risk factor for development of transient cerebral ischemia during clamping. We investigated whether circle of Willis morphology on 3D time-of-flight (TOF) MR angio...

BACKGROUND Delayed cord clamping at birth has shown to benefit neonates with increased placental transfusion leading to higher haemoglobin concentrations, additional iron stores and less anaemia later in infancy, higher red blood cell flow to vital organs and better cardiopulmonary adaptation. As iron deficiency in infants even without anaemia has been associated with impaired development, dela...

INTRODUCTION Laparoscopic partial nephrectomy has emerged as a standard of care for small renal masses. Nevertheless, there remains concern over the potential for irreversible insult to the kidney as a result of exposure to warm ischemia. We aim to investigate the utility of selective segmental arterial clamping as a means to reduce the potential for ischemic damage to a solitary kidney during ...

Microelectrodes are the basis of the techniques discussed in this book. They are used for: (1) potential recording; (2) current injection; (3) introduction into the cell of ionselective resins for measuring potential or determining the free concentration of cytosolic constituents. (1) and (2) are the procedures underlying conventional microelectrode recording, voltage-clamping and patch-clampin...

OBJECTIVE During repair of aortic coarctation, clamping of the transverse aortic arch proximal to the left common carotid artery occludes blood flow to the left carotid and vertebral arteries. The objective of the present study is to determine whether blood flow through the right carotid and vertebral arteries provides adequate cerebral blood flow during aortic cross-clamping, as assessed by ne...

Methodology: This was a randomized, controlled trial performed in Obstetrical Unit with support of Neonatal Unit of Paediatrics and Department of Clinical Pathology of BSMMU on neonates born at term without complication to mothers with uneventful pregnancies. After obtaining written parental consent newborns were randomly assigned to cord clamping within first 15 seconds (group-I Early Cord Cla...

Background: Recently, late umbilical cord clamping is generally recommended, which decreases neonatal anemia; however, it may also increase jaundice and some other poor outcomes. Objectives: We here attempted to determine whether actually increases the incidence of phototherapy for outcomes term “low-risk newborns”. Methods: With approval Brazilian Registry Clinical Trials (REBEC), a total 357 ...
