Causes of previously reported reno-colic fistulas included primary renal and colonic pathologic states involving infectious, malignant or other inflammatory processes. However, reno-colic fistula after renal injury is extremely uncommon. We report an unusual delayed presentation of reno-colic fistula that occurred at 4 months later after blunt abdominal trauma.

TCP Reno is the most popular TCP version right now although it was reported as less efficient than the newer Vegas version. In this paper, we investigate and evaluate the performance of these two TCP algorithms in wireless mobile ad hoc networks, which are characterized by multi-hop wireless connectivity and frequently changing network topology. After extensively comparing of them in simulation...

Hypertension is a very common but incompletely understood disease, especially in its pathogenesis and vascular complications occurring in the cardiovascular research filed. There are many explanations for pathological mechanisms in hypertension, including adrenergic over-reactivity, renin-angiotensin-aldosteron system abnormality and constitutionalgenetic-environmental factors. Recently emergin...

TCP Westwood (TCPW) is a sender-side only modification of TCP Reno congestion control, which exploits end-to-end bandwidth estimation to properly set the values of slow-start threshold and congestion window after a congestion episode. This paper aims at showing via both mathematical modeling and extensive simulations that TCPW significantly improves fair sharing of high-speed networks capacity ...

1. Experiments were carried out to investigate whether the activation of renal chemoceptive receptors by natural stimuli might induce reflex alterations of efferent postganglionic activity to the ipsilateral kidney and preganglionic activity to the ipsilateral adrenal. 2. In anaesthetized rats with intact nervous system back-flow of urine and occlusion of the renal artery were accompanied by in...

This professional paper is composed of three projects: the parallel computation in computational chemistry, the RP-EM-MKL algorithm in pattern recognition, and scientific data visualization. In the first project, the parallel program on the trajectory simulation of N2 + NO collision system was implemented using MPI. High efficiency was obtained and parallel computation could significantly decre...

Hypertension is a major cardiovascular risk factor. Of the many processes involved in the pathophysiology of hypertension, vascular damage due to oxidative stress (excess bioavailability of reactive oxygen species [ROS]) is particularly important. Physiologically, ROS regulate vascular function through redox-sensitive signalling pathways. In hypertension, oxidative stress promotes endothelial d...

The Transmission Control Protocol (TCP) was first proposed and implemented to prevent the future congestion collapses after the congestion collapses in 1986. Since then, it has gone through several phases of improvement, and many new features such as fast retransmit and fast recovery have been added. Recently Brakmo et al. [2] have proposed a new version of TCP, which is named TCP Vegas, with a...

This paper proposes a new rate based congestion control algorithm that significantly improves the utilization of planetary links with respect to classic TCP congestion control. Ns-2 simulation results have shown that the proposed algorithm provides significant goodput improvements with respect to New Reno, Reno Sack, Reno Fack, Vegas, and Westwood+ TCP in the presence of RTTs larger than 1s and...
