The underlying cause of heart disease is a process called atherosclerosis. Atherosclerosis has been described simply as hardening of the arteries, but in truth, it involves a complex interaction of biological processes in the walls of arteries. In atherosclerosis, plaque may build up in the vessels that carry blood to the heart (coronary arteries). When one of these plaques tears or ruptures, a...

BACKGROUND Low blood lead levels previously thought to pose no health risks may have an adverse impact on the cognitive development of children. This concern has given rise to new regulatory restrictions upon lead metal containing products intended for child use. However few reliable experimental testing methods to estimate exposure levels from these materials are available. METHODS The prese...

Many night-flying insects perform complex, aerobatic escape maneuvers when echolocating bats initiate attack. Tiger moths couple this kinematic defense with an acoustic reply to a bat's biosonar-guided assault. The jamming hypothesis for the function of these moth sounds assumes that tiger moth clicks presented at high densities, temporally locked to the terminal phase of the bat attack will pr...

We present new biases in RC4, break the Wi-Fi Protected Access Temporal Key Integrity Protocol (WPA-TKIP), and design a practical plaintext recovery attack against the Transport Layer Security (TLS) protocol. To empirically find new biases in the RC4 keystream we use statistical hypothesis tests. This reveals many new biases in the initial keystream bytes, as well as several new longterm biases...

BACKGROUND Ultrasound observation of fetal movement has documented general trends in motor development and fetal age when motor response to stimulation is observed. Evaluation of fetal movement quality, in addition to specific motor activity, may improve documentation of motor development and highlight specific motor responses to stimulation. AIM The aim of this investigation was to assess fe...

The purpose of this study was to explore the behavioral effects of amniotic fluid (AF) and milk in the newborn rat. Previous research has documented behavioral effects in the fetal and neonatal rat. For example, oral exposure to AF and milk reduces the response to chemosensory stimulation in rat fetuses (Korthank & Robinson, 1998) and newborns (Méndez-Gallardo & Robinson, 2010). In addition, so...

Abstract The price of stocks is a good indication investors’ expectations for the evolution capital markets, comprising their fears and hopes regarding future developments. information disruptive event such as military attack spreads rapidly across countries affecting perceptions causing them to sell target safer investments. scientific literature on topic growing lately due ongoing Russo-Ukrai...

detection and modification of the risk factors of stroke may be the most effective strategy for preventing its often irreversible consequences. a longitudinal prospective study was implemented to evaluate the effect of several risk factors on the course of cerebrovascular disease. the study groups were composed of 3s8 normal volunteers, and 308 patients with transient ischemic attacks. the two ...
