We sometimes run across difficulty in dissection of the pulmonary arteries due to dense pleural adhesions and bleeding from the pulmonary artery during the video-assisted thoracoscopic surgery (VATS) lobectomy. In these cases, conversion of the VATS approach to open thoracotomy is a requisite. The presence of an easy and safe technique for pulmonary artery clamping will make the switch of the s...

We have previously proposed that complexin cross-links multiple pre-fusion SNARE complexes via a trans interaction to function as a clamp on SNARE-mediated neurotransmitter release. A recent NMR study was unable to detect the trans clamping interaction of complexin and therefore questioned the previous interpretation of the fluorescence resonance energy transfer and isothermal titration calorim...

1. We quantitated the effect of biliary diversion on cyclosporin (CyA) absorption in liver transplant patients. Multiple blood samples were obtained over one dosing interval following oral CyA administration in eight liver transplant patients before and after T-tube clamping. 2. Cyclosporin concentrations were measured by a high pressure liquid chromatographic method. 3. The mean (+/- s.d.) dos...

Use of closed drainage systems after total knee arthroplasty (TKA) is a routine practice. Currently, a debate exists regarding whether temporary or no clamping is optimal. A systematic review of the English literature was conducted, and randomized controlled trials comparing all forms of temporary or no clamping drainage were included. Two authors independently extracted articles and predefined...

OBJECTIVE During partial nephrectomy, renal hypothermia has been shown to decrease ischemia induced renal damage which occurs from renal hilar clamping. In this study we investigate the infusion rate required to safely cool the entire renal unit in a porcine model using retrograde irrigation of iced saline via dual-lumen ureteral catheter. MATERIALS AND METHODS Renal cortical, renal medullary...

BACKGROUND Clamping and cutting of the umbilical cord is the most prevalent of all operations, but the optimal timing of cord clamping is controversial, with different timings offering advantages and disadvantages. This study, for the first time, compares the influence of early and late cord clamping in correlation with oxidative stress and inflammation signaling, Because cord clamping timing m...

At present, power electronics-based technologies are widely penetrating the power systems in an effort towards “smart-oriented” operational systems. Voltage-sourced converters (VSCs) are such power electronics-based technologies that currently seem rather to preponderate in many promising applications including FACTs, HVDC grids, DGs and VSDs. VSCs are found in a plethora of structures ranging ...

where s is the curvilinear abscissa along the organ, from the base s = 0 to the tip of the organ s = L and t is the time. νA(L, t) is the apical photoceptive term, readily transmitted all along the organ, and γC(s, t) is the proprioceptive term. Let now the initial conditions be a straight but tilted organ and the boundary conditions of a basal perfect clamping, : A(s, 0) = A(0, t) = A0 C(s, 0)...

A set of experimental procedures, based upon the moire fringe method has been used for measuring elasto-plastic strains in a lug. Results of experiments conducted on aluminium specimens have been presented and discussed. It is found that moire fringe method gives reliable measurement of strain in lug. INTRODUCTION In aircraft, lug type joints are frequently used in connecting structural element...
