RNA immunoprecipitation and real-time quantitative PCR STAU1 or STAU2 antibodies (MBL International, Woburn, MA) were conjugated to magnetic DynaBeads (Life Technologies) according to the manufacturer’s instructions. Differentiated SH-SY5Y cells were gently harvested by adding chilled lysis buffer containing protease and RNAse

inhibitors to the cultures for 5 min. The lysate was collected and an aliquot was saved for analysis of total RNA, while the remainder was incubated with antibody-conjugated DynaBeads for 1 h at 4°C. The beads were then washed and spiked with synthetic RNA as an internal control. RNA was simultaneously isolated from the immunoprecipitated samples and total lysate aliquots Inhibitors,research,lifescience,medical by Trizol-chloroform extraction. The concentration and purity of RNA were determined using an ND1000 spectrophotometer (NanoDrop Technologies, Wilmington, Inhibitors,research,lifescience,medical DE). Synthesis of cDNA was carried out using High Capacity cDNA see more Reverse Transcription Kit (Applied Biosystems, Foster City, CA), with 1 μg of RNA per 20-μL reaction. For real-time quantitative Inhibitors,research,lifescience,medical PCR (RT-qPCR), 100 ng of the cDNA was used in 5-μL reactions with PerfeCTa SYBR Green FastMix (Quanta Biosciences, Gaithersburg,

MD). Reactions were carried out in triplicate in a LightCycler 480 II thermal cycler (Roche, Indianapolis, IN). Cycling conditions followed the manufacturer’s suggestions in the SYBR Green kit instructions. All qPCR results were normalized to the spiked synthetic RNA or endogenous Inhibitors,research,lifescience,medical hypoxanthine-guanine phosphoribosyltransferase (HPRT) mRNA expression and analyzed using Absolute Quantification Software (Roche). Imaging Fluorescence imaging of primary cultures and stained sections were Inhibitors,research,lifescience,medical performed on a Zeiss LSM 5 Pascal laser confocal inverted microscope equipped Ar and HeNe lasers. AlexaFluor-488, -546, and -633 secondary antibodies with directly conjugated fluorophores were used to detect primary antibody signals. Images were acquired using

the included LSM software, and were analyzed using ImageJ. Bright-field imaging below was performed using an upright Zeiss AxioScope 2 Plus microscope equipped with an ASI motorized stage and Zeiss Axiocam MRc camera. Statistical analysis Data were analyzed using Microsoft Excel (Redmond, WA), and plotted using GraphPad Prism software (San Diego, CA). Unpaired t-tests were performed for protein expression in synaptosome experiments and mRNA expression in RT-qPCR experiments. The significance criteria were set at P < 0.05 for statistical measures. Results Selenoprotein W is abundant in the mammalian brain and its mRNA is found in mouse brain neurons; however, the cellular location of the protein has not been described. We sought to determine whether Sepw1 is expressed in neurons of mouse brain, and if neuronal expression of Sepw1 is reduced in Sepp1−/− mice.

Background Alexander et al5,7-9 proposed that the basal ganglia and thalamus participate in five parallel segregated circuits with selected cortical areas in the frontal lobe. Two of these circuits are related to motor function, and influence skeletomotor and learn more oculomotor areas of cortex. The remaining three loops are connected with nonmotor areas in the frontal lobe, including the dorsolateral prefrontal cortex, the lateral orbitofrontal cortex, and the anterior cingulate/medial

orbitofrontal cortices. These frontal regions are known to be Inhibitors,research,lifescience,medical involved in aspects of planning, working memory, rule-based learning, attention, and emotional regulation such as the decision threshold in reaction time tasks or in the control of automatic Inhibitors,research,lifescience,medical visuospatial

attention.10-42 Basal ganglia functional connectivity, based on a recent meta-analysis of 126 positron emission tomography (PET) and fMRI imaging publications, showed that patterns of functional connectivity between the cortex and the striatal nuclei are broadly consistent with the predictions of this classical parallel loop model.13 The frontal lobe may be viewed as comprising two distinct anatomical Inhibitors,research,lifescience,medical and functional systems, reflecting its dual developmental origin.14 The sequential processing of sensory, spatially related, and motivational Inhibitors,research,lifescience,medical information is mediated by a dorsal system, which involves dorsolateral and medial portions of the frontal lobes, interconnected with the posterior parietal lobe and cingulate gyrus. Emotional tone is mediated by a second, ventral system, which involves the orbital surface of the frontal lobes. The function of

the frontal lobes as an integrator of infermation, related both to the external sensory and internal limbic worlds and its role in motivation and appropriate nections Inhibitors,research,lifescience,medical critically important to an understanding of both normal and disordered psychomotor functions. The architectonic organization of the prefrontal cortex is reflected in the pattern of prefrontostriatal projections.15,16 The dorsal architectonic trend, which originates Rolziracetam in the rostral cingulate gyrus and culminates in the dorsal portion of the frontal eye field, maps onto the dorsal caudate nucleus. In contrast, the ventral architectonic trend, which originates in the ventral orbital region and culminates in the ventral portion of the frontal eye field, maps onto the ventromedial portion of the caudate and the adjacent portion of the nucleus accumbens. Cortical areas that are closely connected functionally appear to send converge ing projections into adjacent regions of the striatum.17-20 Information derived from the cortex is recombined at the striatal level to form small, functionally specialized domains.

et al. 1999; Engel et al. 2006; Leroy et al. 2010], reducing their ability to bind to microtubules, leading to the promotion of microtubule assembly [Hong et al. 1997; Munoz-Montano et al. 1997] and increased axonal spreading and increases in the growth cone area and perimeter [Garcia-Perez et al. 1998], respectively. Thus, lithium-induced GSK3 inhibition can disrupt microtubule assembly, with effects on cytoskeletal protein association dynamics mediating neuroplastic changes [Lenox and Hahn, 2000]. Downstream Inhibitors,research,lifescience,medical effects on cytoskeletal growth stabilisation and plasticity also occur following disruption of the PKC signalling pathway, a secondary effect of lithium-induced IMPase inhibition [Manji and Chen, 2002].

Chronic lithium treatment downregulates the expression of the PKC substrate ‘myristoylated alanine-rich C kinase substrate’ (MARCKS), a protein associated with long-term neuroplastic events in the developing Inhibitors,research,lifescience,medical and adult brain Inhibitors,research,lifescience,medical [Manji and Lenox, 1999]. Induction of autophagy Autophagy is a physiological process for the bulk degradation of cytoplasmic proteins or organelles [Sarkar et al. 2005] and an important regulator of cellular (including neuronal) survival and function [Chiu and Chuang, 2010]. Lithium alters rates of autophagy through both the GSK-3β and IMPase pathways, with dose-dependent effects. Lithium-induced IMPase inhibition at lower doses (Ki ≈ 0.8 mM) can enhance autophagy [Sarkar et al. 2005], whilst inhibition of GSK-3β by higher doses Inhibitors,research,lifescience,medical of lithium (Ki ≈ 2 mM) suppresses autophagy, by varying activation of the negative regulator mTOR [Sarkar et al. 2008; Chiu and Chuang, 2010]. Glutamate receptor functions The Akt/GSK3 signalling pathway has been implicated in the downstream

regulation of ionotropic glutamate receptor functions [Beaulieu et al. 2009]. Notably, activation of GSK3 has been shown to inhibit the development of CI1033 glutamatergic N-methyl-D-aspartate (NMDA) receptor-dependent long-term potentiation Inhibitors,research,lifescience,medical (LTP), causing changes to neuronal synaptic plasticity and contributing to learning and memory deficits [Zhu et al. 2007]. In addition, GSK3 inhibition has been Urease shown to prevent the development of long-term depression (LTD) in rat hippocampal slices [Peineau et al. 2007], reducing the efficacy of neuronal synapses. Control of intracellular calcium concentration There is a general consensus that chronic lithium treatment may modify one or more calcium signalling pathways in the brain [Sourial-Bassillious et al. 2009]. The effects of lithium on the PI signalling pathway, for example [Berridge et al. 1989], leads to a reduction in levels of IP3, an important stimulator for intracellular calcium (Ca2+) levels [Sourial-Bassillious et al. 2009].

We have evidence that neuronal activity, including that driven by afferent input, regulates acquisition and loss of the DA phenotype by substantia nigra pars compacta (SNc) neurons in adult mice. Hypotheses The aims of the present study were to determine whether the environment or behavior regulates the number of SNc DA neurons in adult mice, and whether this is mediated by

afferent input. Methods Adult mice were subject to two different environments/behaviors: “mating” for 1 week or “environment enrichment” (EE) for 2 weeks; then the Inhibitors,research,lifescience,medical numbers of tyrosine hydroxylase (TH, the rate limiting enzyme in DA synthesis) immunopositive (TH+) and immunonegative (TH−) SNc neurons were counted. Results More TH+ neurons were present in mated males whereas less TH+ neurons were present in mated females. Also, more TH+ neurons were Inhibitors,research,lifescience,medical present in EE males, and this increase was completely abolished by concurrent local infusion of GABAA receptor antagonists. Conclusions The number of DA neurons in the adult SNc is not fixed, but readily increases and decreases in R788 mouse response to environmental stimuli and/or behaviors. These changes are mediated Inhibitors,research,lifescience,medical by afferent

input relaying information about the environment or behavior to SNc neurons. Keywords: Dopamine, midbrain, plasticity Introduction Behavioral adaptation to our environment is mediated by changes in our nervous system. In adults these changes include altered connectivity between neurons (synaptic plasticity) and limited generation of new neurons (neurogenesis). There is, however, evidence of another form of “plasticity,”

Inhibitors,research,lifescience,medical which involves neurons changing the levels of expression of, or identity of their neurotransmitter (Zigmond et al. 1980; Baker et al. 1983; Black et al. 1985, 1987; Richard et al. 1988; Biguet et al. 1989; Schalling et al. 1989; Liaw et al. 1992; Aumann et al. 2011; Dulcis et al. 2013). For example, acquisition or loss of the capacity of hypothalamic Inhibitors,research,lifescience,medical neurons to synthesize and release dopamine (DA) in response to environmental stimuli has functional and behavioral consequences for adult rats (Dulcis et al. 2013). We too have reported evidence for acquisition and loss of the DA phenotype by adult substantia nigra pars compacta (SNc) neurons in response to altered neuronal activity (Aumann et al. 2008, 2011) or following 6-hydroxy-dopamine however (6-OHDA) lesions (Stanic et al. 2003). Our data further suggest that afferent input to SNc regulates this “DA phenotype switching” (Aumann et al. 2011). This implicates behavior and/or the environment in regulating the number of DA neurons in the adult SNc, via afferent input. The aims of the present study were to determine: (1) whether the number of SNc DA neurons changes in mice undergoing natural behaviors; (2) which kinds of behavior best induce these changes; and (3) whether afferent input is involved.

There are newer models and strategies for effective bedside teaching. The core message of such models is the educational process. A bedside teacher must learn how to involve patients and learners in the educational process. Maintaining a comfortable environment for all participants; the learner, the patient and the bedside teacher is very important. It is through this process that the learners acquire the skills

of observation, communication, examination and professionalism. Medical schools should give due importance to bedside teaching, and must renew and increase the efforts to get ahead of this past shapers of the profession. Conflict of Interest: None declared
We thank Inhibitors,research,lifescience,medical Dr Cascella for his insightful comments and the opportunity to clarify a number of points from our work. Anesthesia is not a single pharmacologic process. Rather, it is a complex interaction of multiple stimuli, diverse responses and drug-induced probability of non-responsiveness to stimuli. Anesthesia is defined by its hypnotic Inhibitors,research,lifescience,medical (unconsciousness) and analgesic (pain relief) components. The hypnotic effects of the intravenous and inhaled anesthetics can be measured with empirically Inhibitors,research,lifescience,medical derived indices calculated from an EEG, such as the Bispectral Index (BIS).1 However BIS may not be a gold standard monitor for the evaluation of all components of anesthesia depth. There

is emerging evidence that intra-operative monitoring of the hypnotic component of an anesthetic Inhibitors,research,lifescience,medical regimen may decrease the risk of awareness associated with anesthesia. Perhaps it is better to state that we have used BIS to learn more evaluate the adequacy of the hypnotic component of our general anesthesia regimen in C/S patients. In response to your opinion about our small sample size Inhibitors,research,lifescience,medical for evaluation of awareness, it is exactly acceptable. However, it was not our intent to study the incidence of awareness in these cases. We have only collected and reported awareness as non-conclusive data. Additionally, we asked our patients to inform us about any probable recollections over the days following discharge

from the hospital. In this regard, we did not receive any ongoing data. We are in complete agreement with your explanations regarding explicit memory, consciousness, recall, awareness and post-traumatic stress syndrome. Isotretinoin In the near future, we hope to attain new technologies and monitoring systems for complete, accurate evaluation of anesthesia depth.
In addition to a suture placed between the skin of the chin point and anterior part of the upper chest in the midline position, we have designed a fiberglass-made brace that weighs 800 g (figure 1) with the intent to maintain constant complete neck flexion, post-operatively, in patients who refer to our center for tracheal reconstruction. The brace is 100 cm in length and extends from the occiput to the sacrum.

These behaviors depend on the context and the repertoire of the species. Active coping strategies are used when escape from threat is possible, and the autonomic changes associated with these active strategies are mediated predominantly by sympathetic activation (hypertension, tachycardia). This is the fight-or-flight response originally described by Cannon.17 Passive coping strategies, such as immobilization or freezing, are usually elicited when threat is inescapable, and are usually characterized by autonomic inhibition (hypotension, bradychardia), and a more pronounced increase in the neuroendocrine response Inhibitors,research,lifescience,medical (activation of the hypothalamopituitary-adrenal axis and increased glucocorticoid

secretion). This type of passive response was originally described by Engel and Schmale as a conservation-withdrawal strategy.18 The concept of alternative (active/passive) strategies itself owes much to the work of Henry and coworkers.

19 Specific brain circuits appear to mediate distinct coping reactions to different types Inhibitors,research,lifescience,medical of stressors.20,21 Inhibitors,research,lifescience,medical According to Panksepp, flight and other active coping behaviors are unconditional responses to proximate threat, whereas passive coping strategies, such as freezing, are conditioned responses to distal stimuli predictive of danger. These two strategies have distinct and successive roles, and are modulated by the (cognitive) apprehension of the environment and probability of success, eg, whether or not there is a route of escape. Thus, when an animal faces a predator, freezing is preferentially activated when the source of known danger is still far Inhibitors,research,lifescience,medical away. When danger gets closer, and the stimulus passes through some critical “psychometric” distance, it becomes a true unconditional stimulus and a flight pattern

is activated.22 Defensive behaviors have been studied in a large number of species,23 and it has recently been shown that human defensive behaviors to threat scenarios arc not unlike those seen in nonhuman mammals.24 The importance of risk assessment in making a proper decision about the best strategy to be used in a particular Inhibitors,research,lifescience,medical context has been emphasized.25 It should be underlined, however, Edoxaban that the choice between an active or passive defense strategy does not entirely depend on contextual clues. Individual differences in coping styles do exist and may also influence this choice. In a given situation, some individuals may react actively (“proactive” style), whereas other individuals may react in a more passive way (“reactive” style). These coping styles are characterized by consistent behavioral and neuroendocrine patterns, and may explain individual differences in vulnerability to stress-induced diseases.26 Differences in coping styles have also been found between various strains of mice,27 or between Selleck 10058 F4 genetically selected rat lines,28 which suggests that they have a genetic basis.

On

subsequent intracellular injection of hyperpolarizing current (−1 nA), the spike bursts of T3-DO became grouped into the normal chirp pattern, and at the same time, the motor output of fictive singing was instantaneously reconstituted (Fig. 6E). Ascending opener-interneuron A1-AO We also identified an ascending interneuron in the metathoracic ganglion complex that spiked rhythmically in phase with the wing-Roscovitine cell line opener Inhibitors,research,lifescience,medical activity and that was inhibited in phase with the wing-closer motoneurons. Its soma was located at the lateral margin of the first fused abdominal neuromere A1, from where its primary neurite ran dorsally toward the posterior border of the metathoracic neuromere (Fig. 7A). Forming a loop near the ganglion midline, the main neurite sharply bent anteriorly and the ascending axon projected through the ipsilateral connective toward the mesothoracic ganglion. Before leaving the ganglion, the Inhibitors,research,lifescience,medical axon gave off a side branch that ramified dorsally in the anterior metathoracic neuromere. Arising from the neurite, the main dendrite of A1-AO formed a dense meshwork of fine branches projecting anteriorly and posteriorly along the dorsal midline of the neuromeres A1 and A2. Figure 7 Structure and activity of the

ascending opener-interneuron A1-AO. (A) Cell body position and dendrites of A1-AO in the fused abdominal–metathoracic ganglion Inhibitors,research,lifescience,medical complex (ventral view); the axon ascends toward the mesothoracic ganglion. (B) and (C) … During fictive Inhibitors,research,lifescience,medical singing, the membrane potential of A1-AO

depolarized by 4–8 mV in each opener phase and hyperpolarized by 4–5 mV in phase with the closer-motoneuron activity (Fig. 7B). Every depolarization gave rise to a burst of 3–6 action potentials with an instantaneous spike frequency of 140–180 Hz. During each syllable, A1-AO fired its first spike 7.5 ± 1.1 msec (mean ± SD; N = 1, n = 50) before the first spike of the wing-opener motoneuron activity and 31.2 ± 1.2 msec (mean ± SD; N = 1, n = 50) before the Inhibitors,research,lifescience,medical first spike of the wing-closer activity. During the chirp intervals, the neuron spiked tonically at a rate of 100–120 Hz. This tonic background activity might result from a slightly elevated membrane potential due to the microelectrode penetration. Constant hyperpolarizing current injection in the PAK6 dendrite of A1-AO completely prevented tonic spiking during the chirp intervals and also reduced the rhythmic spike activity during chirps (Fig. 7C). The spike activity reduction in A1-AO did not affect the singing motor pattern and neither strong depolarizing nor hyperpolarizing current pulses reset the chirp rhythm of fictive singing. Closer interneurons While recording in the abdominal neuromeres, we encountered considerably more often opener interneurons than closer interneurons. Nevertheless, in 12 crickets, we recorded interneurons whose rhythmic spike activity was strictly coupled to the closer phase of fictive singing.

Neuropsychiatric side-effects have been reported in up to 60% of patients undergoing treatment with antiviral agents [Evon et al. 2009]. Most of them (48%) were depressive disorders. More rarely, signs and symptoms associated with anxiety, sleep, memory and attention disorders were observed [Lochet et al. 2003; Ward and Curtin, 2006]. Ribavirin, an antiviral agent, has also been reported to cause some psychiatric syndromes, however it is stressed that these effects are often enhanced by the psychiatric side-effects of the other Inhibitors,research,lifescience,medical antiviral agents (such as interferon alpha) which are often used together [Reichard

et al. 1997; Martin-Santos et al. 2008]. We would like to report a case of single-agent ribavirin-induced compulsive buying. The purpose of Inhibitors,research,lifescience,medical this case report is to draw attention to obsessive compulsive spectrum disorders (OCSDs) such as compulsive buying, which, although

not defined as a disorder by the DSM and ICD, may cause clinically significant disability, and also Inhibitors,research,lifescience,medical to its etiology of biological and psychological explanations. A 34-year-old woman presented to our mTOR inhibitor clinic with obsessive fears of becoming contaminated by microbes whenever she touches any item, continuous thoughts of having forgotten to turn the lights off and close windows and doors, uncontrolled repetitive behaviors in the form of a compulsive need to constantly check the doors or lights or continuously wash her hands. She also had sudden and intense desires

to shop and purchase things needlessly. When she postponed Inhibitors,research,lifescience,medical the desire to shop, she experienced severe discomfort and restlessness. She gained relief by buying unnecessary things, hence she faced economical problems due to excessive expenditure, resulting in regret and anxiety feelings. Three weeks prior to her application, she received a prophylaxis treatment consisting of 1000 mg/day oral Inhibitors,research,lifescience,medical ribavirin applied for 7 days since she had pricked her finger with a syringe that had been used on a patient with Crimean-Congo hemorrhagic fever disease. During the medication usage she had no complaint Etomidate other than a feeling of dizziness and lack of concentration. The prophylaxis treatment for Crimean-Congo hemorrhagic fever disease was completed and the disease did not appear. The aforementioned psychiatric symptoms and complaints started a week after the completion of this treatment with ribavirin. It was determined via psychiatric examination that she was in an anxious–angry mood, her thoughts included suspicion and contamination obsessions, control and washing compulsions, and intense desire to go shopping; her behavior of purchasing unnecessary things was noted and, after purchasing, she experienced thoughts of guilt. Routine hematological and biochemical parameters were normal.

For patients with metastatic colorectal cancer who have progressed beyond all other approved standard systemic therapies, regorafenib has proven clinical benefit. This was demonstrated in the CORRECT study (8). Patients had to have received treatment including a fluoropyrimidine, selleck compound oxaliplatin, irinotecan, bevacizumab, and, for patient who had a Kras wild-type tumor, cetuximab or panitumumab. Patients were randomized to receive either regorafenib 160 mg by mouth once daily, for days 1-21 of a 28 day cycle,

or a placebo. A statistically significant, marginal clinical benefit of 1.4 months of overall survival was observed Inhibitors,research,lifescience,medical in the regorafenib arm compared to placebo. Response rates were low in both trial arms and did not achieve statistical significance, but disease control rates were significantly higher in the Inhibitors,research,lifescience,medical regorafenib arm.

Notably, regorafenib is the first agent with activity as a VEGF-receptor tyrosine kinase inhibitor to have benefit in metastatic colorectal cancer, whereas a number of other such agents have failed, as previously described. Given the wider range of tyrosine kinases that regorafenib inhibits, it is not clear whether this clinical benefit of regorafenib is attributable to its anti-VEGF activity or to another of its targets. For this survival benefit in the CORRECT trial, 54% of treatment patients experienced grade 3 or 4 adverse events, Inhibitors,research,lifescience,medical compared to 14% experienced by patients in the placebo arm (8). Adverse events of grade 3 or 4 that occurred notably higher

in the treatment arm when Inhibitors,research,lifescience,medical compared to the control arm included hand/foot syndrome, fatigue, diarrhea, hypertension, and rash. On the basis of the CORRECT study, regorafenib has garnered approval for patients with metastatic colorectal cancer who have progressed beyond all other available standard therapies. Presently, there is no approved role for this agent, outside of a clinical trial, in patients who still have other approved options available for the treatment of their metastatic colorectal cancer. Conclusions Anti-angiogenic agents have emerged as an important Inhibitors,research,lifescience,medical tool in the management of patients with metastatic colorectal cancer, in all lines of therapy, Endonuclease and in conjunction with a number of different chemotherapy regimens. Bevacizumab has applications in the first and second lines of metastatic therapy and remains the only anti-angiogenic agent approved in the first line setting. Ziv-aflibercept has also demonstrated a survival benefit in the second-line setting, in combination with chemotherapy. The anticancer activity demonstrated with regorafenib in the third line (or beyond) setting, even after prior anti-VEGF therapy demonstrates that there is a role and benefit for anti-angiogenic therapy throughout the continuum of care for patients with metastatic colorectal cancer, and that benefit may be seen with different agents, which target different parts of the angiogenic process.

Major short-notice or sudden impact (known as big bang Inhibitors,research,lifescience,medical [1]) incidents which result in a large number of casualties are, fortunately, rare events. However they do occur and health services must be prepared to respond appropriately. In the United Kingdom (UK), as with most developed countries, normal response ambulances will not have the capacity to carry the extra equipment which is required Inhibitors,research,lifescience,medical to care for these patients while at the incident [2]. In order to

deal with a big bang mass casualties incident, National Health Service (NHS) organizations, including ambulance services must be supported by extraordinary measures [1]. As part of their role UK NHS ambulance services maintain and deploy extra selleck screening library clinical equipment for big bang mass casualties emergencies [2]; and, on arrival Inhibitors,research,lifescience,medical at such an incident, establish and manage a casualty clearing station. Individuals are then triaged and receive emergency medical treatment as required before transportation to hospital. However, the Inhibitors,research,lifescience,medical London Assembly Report into the 2005 London Bombings highlights the challenges of achieving this in practice: The London Ambulance Service lacked essential supplies, such as fluids triage cards and tourniquets, at all sites [3]. Predicting the types and quantities of clinical equipment that will be required at a mass casualties big bang event is difficult. It is necessary to consider the wide range of incidents [1], both natural and man-made, that could cause such an event, and the resultant broad spectrum of potential Inhibitors,research,lifescience,medical clinical need:- e.g. haemorrhage, burns, respiratory disorders; fractures; effects of smoke inhalation etc. The response must also be tailored to the level

of care that can be practically delivered in a pre-hospital environment. A recent systematic review highlighted the lack of Casein kinase 1 evidence to inform policymakers and service providers about the types and quantities of clinical equipment required at a mass casualties big bang event [4]. Current UK ambulance service provision of clinical equipment at big bang mass casualties incidents has developed on the basis of local clinical judgment over many years, without any central co-ordination or clear evidence-base. This has resulted in variations in stock type and quantity throughout the UK. Agreeing the types and quantities of clinical equipment required at a big bang mass casualties emergency would be advantageous. At a national level it would provide policy and strategic decision-makers with knowledge to support them in planning future service provision.
