Central venous pressure generally indicates right sided cardiac filling pressure. Although it is a static hemodynamic parameter, however trend of CVP gives important information regarding the patient's management. Patient with left ventricular assist device is prone to develop right ventricular dysfunction which can easily be suspected by trend of CVP. However rising CVP does not always imply r...

In silico substrate docking of both stereoisomers of the pesticide chlorfenvinphos (CVP) in the phosphotriesterase from Agrobacterium radiobacter identified two residues (F131 and W132) that prevent productive substrate binding and cause stereospecificity. A variant (W131H/F132A) was designed that exhibited ca. 480-fold and 8-fold increases in the rate of Z-CVP and E-CVP hydrolysis, respectivel...

BACKGROUND In order to assessment of intravascular fluid measurement of central venous pressure (CVP) is used via central venous catheterization (CVC). This procedure is highly invasive and may cause serious complications such as pneumothorax, infection, hematoma and etc. It is so valuable procedure if we can uses a less invasive or noninvasive procedure to assess patients intravascular fluid i...

We present a 2 O(n) time Turing reduction from the closest lattice vector problem to the shortest lattice vector problem. Our reduction assumes access to a subroutine that solves SVP exactly and a subroutine to sample short vectors from a lattice, and computes a (1+)-approximation to CVP. As a consequence, using the SVP algorithm from 1], we obtain a randomized 2 O(1+ ?1)n algorithm to obtain a...

We prove a connection of the worst-case complexity and the average-case complexity for the Closest Vector Problem (CVP) for lattices. Assume that there is an eecient algorithm which can solve approximately a random instance of CVP for lattices under a certain natural distribution, at least with a non-trivial success probability over this distribution, we show that one can approximately solve se...

To the Editor: Recently, an updated Practice Advisory has been published regarding perioperative visual loss associated with spine surgery. I feel the need to highlight certain statements in the Advisory that are contradictory to the long-standing effort in the anesthesiology/critical care communities to place fluid management on a more rational basis. Starting decades ago, significant effort h...

BACKGROUND Central venous pressure (CVP) is an important factor affecting capillary blood flow, and it is associated with poor outcomes in adult septic shock patients. However, whether a similar association exists in pediatric patients remains unclear. METHODS We retrospectively analyzed data from patients admitted to our pediatric intensive care unit (PICU) between February 2009 and July 201...

conclusions noninvasive assessment of the patient hydration condition using the ultrasound is a simple and practicable measure in emergency. with regard to the considerations, it is possible to estimate cvp via diameter measurement and cross-section of the central veins. results twenty patients with the mean age of 60.3 were studied. the main reason for cardiac catheterization was shock. there ...

We prove a connection of the worst-case complexity to the average-case complexity based on the Closest Vector Problem (CVP) for lattices. Assume that there is an efficient algorithm which can solve approximately a random instance of CVP, with a non-trivial success probability, for lattices under a certain natural distribution, we show that one can approximately solve several lattice problems (i...
