BACKGROUND Potency of inhaled anesthetics (minimum alveolar concentration [MAC]) is typically studied in humans using an "up-down" approach in which the (quantal) response to skin incision is assessed only once for each individual, so that each individual's MAC is never determined. The authors examined the influence of interindividual variability and study design issues (e.g., the number of pat...

The antimycotic action of 1, 4-bis-(m, m'-amidinophenoxymethyl)-cyclohexane dilactate (MAC), a synthetic diamidine compound, on Candida albicans was studied. The minimum inhibitory concentration (MIC) ranged from 3.31 to 6.25 micrograms/ml against both standard and clinically isolated strains. MAC was fungistatic at MIC and weakly fungicidal at the concentration of 100 micrograms/ml. MAC did no...

A wireless sensor network is an ad hoc network and consists of a number of sensor nodes spread across a geographical area. Each sensor node is a tiny battery operated device and has a processor for computing and transceiver for communication. Instead of conventional network measures such that throughput, latency and bandwidth utilization, energy consumption has great importance and radio part o...

OBJECTIVES The coexistence of lung cancer and pulmonary Mycobacterium avium complex (MAC) infection has not been well reported. This study illustrated the clinical characteristics of pulmonary MAC infections complicated with lung cancer. PATIENTS AND METHODS We conducted a retrospective analysis of the clinical characteristics of patients with pulmonary MAC infections complicated with newly d...

While the leukocyte integrin lymphocyte function-associated antigen (LFA)-1 has been demonstrated to bind intercellular adhesion molecule (ICAM)-1, results with the related Mac-1 molecule have been controversial. We have used multiple cell binding assays, purified Mac-1 and ICAM-1, and cell lines transfected with Mac-1 and ICAM-1 cDNAs to examine the interaction of ICAM-1 with Mac-1. Stimulated...

Most current WSN MAC protocol implementations have multiple tasks to perform—deciding on correct timing, sending of packets, sending of acknowledgements, etc. However, as much of this is common to all MAC protocols, there is duplication of functionality, which leads to larger MAC protocol code size and therefore increasing numbers of bugs. Additionally, extensions to the basic functionality mus...
