To the Editor:—A review of the classic anesthesiology literature reveals a common thread in the instructions for direct laryngoscopy: To successfully visualize the larynx, one must align three (oral, laryngeal, and pharyngeal) anatomic axes. Placing a patient in the “sniffing position” is the accepted maneuver for aligning these axes. Recently, we evaluated a radiograph obtained during intubati...

Monitoring of Wireless Sensor Networks (WSNs) is a fundamental task to track the network behavior and measure its performance in real-world deployments. Commercially-available products for monitoring and testing IEEE 802.15.4-compliant Low Power Wireless Personal Area Networks (LoWPANs) are mainly too expensive, and typically require special sniffing hardware. In this Demo paper, we present Z-M...

Introduction: Effects of stress on nervous system activity and development are well defined. In the present study, the effects of maternal stress on dopamine-related behavior in the offspring were studied. Methods: Female pregnant Wistar rats (200 g) were randomly exposed to the noise pollution stress (125 db) for 14 days (5 min/day). The time of exposure was random in order to avoid adaptat...

Four case histories of a representative sample of young adult glue sniffers who had progressed to using illicit drugs or abusing alcohol or both contained several common factors that may have been relevant in the transition. For example, all had suffered parental deprivation or rejection in childhood leading to a state of chronic stress, and all had progressed from sniffing glue to inhaling her...

This paper focuses on the threat of packet sniffing in a switched environment, and briefly explores the effect in a non-switched environment. Detail is given on techniques such as "ARP (Address Resolution Protocol) spoofing", which can allow an attacker to eavesdrop on network traffic in a switched environment. Third party tools exist which permit sniffing on a switched network. The result of r...

A 12 year old boy who was a habitual glue sniffer developed a dense hemiparesis in association with an episode of glue sniffing. Occlusion of the right middle cerebral artery was found. It is postulated that the stroke was precipitated by an episode of vascular spasm.

Food odours are major determinants for food choice, and their detection depends on nutritional status. The effects of different odour stimuli on both behavioural responses (locomotor activity and sniffing) and Fos induction in olfactory bulbs (OB) were studied in satiated or 48-h fasted rats. We focused on two odour stimuli: isoamyl acetate (ISO), as a neutral stimulus either unknown or familia...
