BACKGROUND Different video-laryngoscopes (VDLs) for endotracheal intubation (ETI) have recently been developed. We compared the performance of the VDL Airway Scope (AWS) with the direct laryngoscopy by Macintosh (DLM) for ETI success, time and learning. METHODS We performed an experimental manikin controlled study. Twenty experienced (experts) and 40 inexperienced operators (novices) for DLM-...
The objectives of this study were twofold: (1) to characterize the toxicokinetics and dose-dependent systemic/tissue distribution of deltamethrin (DLM) over a range of doses in adult Sprague-Dawley (S-D) rats; (2) to provide comprehensive time course blood and tissue data for development of a physiologically based toxicokinetic (PBTK) model for DLM. DLM is one of the more neurotoxic members of ...
We tested the hypothesis that wing muscle size and triglyceride production mediate a lifehistory trade-off between wing morph (or flight capability) and early fecundity. Roff et al. recently selected for lower number of eggs laid in the first week by Gryllus firmus (sand cricket) and reported a correlated increase in long-winged (and presumably flight-capable) females, but did not test structur...
The aim of the present study was to determine whether increased consumption of methionine as DL-methionine (DLM) or its hydroxy analogue DL-2-hydroxy-4-methylthiobutanoic acid (HMTBA) could benefit milk synthesis and neonatal growth. For this purpose, eighteen cross-bred (Landrace × Yorkshire) primiparous sows were fed a control (CON), DLM or HMTBA diet (n 6 per diet) from 0 to 14 d post-partum...
We have used dipole localization methods (DLMs) to examine multielectrode acoustic brain-stem response (ABR) data for 9 data files collected in 5 experiments on 2 cats. The analytical model for scalp surface voltage consisted of a single current dipole in a homogeneous spherical head model. DLM sources were compared to ABR generator sites determined in intracranial and lesion experiments descri...
The current study was designed to investigate the possible mechanism involved in hyperglycemia induced by chronic exposure to deltamethrin (DLM) in rat and to assess whether this damage is amenable to modulation by Zygophyllum album. DLM, a synthetic pyrethroid pesticide, was administrated at a dose of 4 mg/kg body mass, during 60 days. Compared with control, DLM showed a significant increase o...
Weighted maximum satissability problems (MAX-SAT) are diicult to solve due to the large number of local minima in their search space. In this paper we propose a new discrete Lagrangian based search method (DLM) for solving these problems. Instead of restarting from a new point when the search reaches a local minimum, the Lagrange multipliers in DLM provide a force to lead the search out of the ...
The anterior forebrain pathway (AFP) of the avian song system is a circuit essential for song learning but not for song production. This pathway consists of a loop serially connecting area X in the basal ganglia, the medial portion of the dorsolateral nucleus of thalamus (DLM), and the pallial lateral magnocellular nucleus of the anterior neostriatum (lMAN). The majority of DLM neurons in adult...
We have previously demonstrated that Drosophila synapses possess two vesicle populations-a small active zone population replenished by "fast" recycling and a much larger reserve population replenished by a slower recycling mechanism that includes endosomal intermediates. In this paper, we demonstrate that the synapses onto the tergotrochanteral muscle (TTM) are very unusual in that they possess...
BACKGROUND Deltamethrin (DLM) is a broad-spectrum synthetic dibromo-pyrethroid pesticide that is widely used for agricultural and veterinary purposes. However, human exposure to the pesticide leads to neurotoxicity. Glutamine is one of the principal, free intracellular amino acids and may also be an antioxidant. This study was undertaken in order to examine the neuroprotective and antioxidant p...
