Abstract
Mounting evidence supports the serotonin 2A receptor agonist psilocybin as a psychiatric pharmacotherapy. Little research has experimentally examined how session "set and setting" impacts subjective and therapeutic effects. We analyzed the effects of the musical genre played during sessions of a psilocybin study for tobacco smoking cessation. Participants (N = 10) received psilocybin (20-30 mg/70 kg) in two sessions, each with a different musical genre (Western classical versus overtone-based), with the order counterbalanced. Participants chose one genre for a third session (30 mg/70 kg). Mystical experiences scores tended to be higher in overtone-based sessions than in Western classical sessions. Six of ten participants chose the overtone-based music for a third session. Biologically confirmed smoking abstinence was similar based on musical choice, with a slight benefit for participants choosing the overtone-based playlist (66.7% versus 50%). These data call into question whether Western classical music typically used in psychedelic therapy holds a unique benefit. Broadly, we call for experimentally examining session components toward optimizing psychedelic therapeutic protocols.

Abstract
Skin sensitisation is the regulatory endpoint that has been at the centre of concerted efforts to replace animal testing in recent years, as demonstrated by the Organisation for Economic Co-operation and Development (OECD) adoption of five non-animal methods addressing mechanisms under the first three key events of the skin sensitisation adverse outcome pathway. Nevertheless, the currently adopted methods, when used in isolation, are not sufficient to fulfil regulatory requirements on the skin sensitisation potential and potency of chemicals comparable to that provided by the regulatory animal tests. For this reason, a number of defined approaches integrating data from these methods with other relevant information have been proposed and documented by the OECD. With the aim to further enhance regulatory consideration and adoption of defined approaches, the European Union Reference Laboratory for Alternatives to Animal testing in collaboration with the International Cooperation on Alternative Test Methods hosted, on 4-5 October 2016, a workshop on the international regulatory applicability and acceptance of alternative non-animal approaches, i.e., defined approaches, to skin sensitisation assessment of chemicals used in a variety of sectors. The workshop convened representatives from more than 20 regulatory authorities from the European Union, United States, Canada, Japan, South Korea, Brazil and China. There was a general consensus among the workshop participants that to maximise global regulatory acceptance of data generated with defined approaches, international harmonisation and standardisation are needed. Potential assessment criteria were defined for a systematic evaluation of existing defined approaches that would facilitate their translation into international standards, e.g., into a performance-based Test Guideline. Informed by the discussions at the workshop, the ICATM members propose practical ways to further promote the regulatory use and facilitate adoption of defined approaches for skin sensitisation assessments.

Abstract
Research conducted during past decades to reduce the level of the tobacco specific nitrosamine N-nitrosonornicotine (NNN) and its precursor nornicotine in tobacco yielded identification of three tobacco genes encoding for cytochrome P450 nicotine demethylases converting nicotine to nornicotine. We carried out trials to investigate the effect of using tobaccos containing three non-functional nicotine demethylase genes on the selective reduction of NNN in cigarette tobacco filler and mainstream smoke. Our results indicate that the presence of non-functional alleles of the three genes reduces the level of nornicotine and NNN in Burley tobacco by 70% compared to the level observed in currently available low converter (LC) Burley tobacco varieties. The new technology, named ZYVERT™, does not require a regular screening process, while a yearly selection process is needed to produce LC Burley tobacco seeds for NNN reduction. The reduction of NNN observed in smoke of blended prototype cigarettes is proportional to the inclusion level of tobacco having ZYVERT™ technology. Inclusion of Burley tobacco possessing the new trait into a typical American blend resulted in a selective reduction of NNN in cigarette smoke, while the levels of other Harmful and Potentially Harmful Constituents (HPHC) currently in the abbreviated list provided by the US Food and Drug Administration are statistically equivalent in comparison with the levels obtained in reference prototype cigarettes containing LC Burley.

Abstract
In this study, the in vitro effects of interleukin 6 (IL-6) on the messenger RNAs (mRNAs) and proteins for key steroidogenic factors in the bovine adrenal zona fasciculata (ZF) were determined. Bovine adrenal glands were obtained from an abattoir, and the ZF was isolated. Strips of ZF were then exposed to different concentration of murine IL-6 and/or adrenocorticotropic hormone (ACTH) for various intervals, the protein and mRNA extracted, and the mRNA and protein expression determined by real-time polymerase chain reaction and Western blots. Exposure (1 h) to IL-6 increased in a concentration-dependent manner (10-pg IL-6/mL, P < 0.05 vs control; 100-pg IL-6/mL, P < 0.01 vs control) the relative expression of the mRNAs and proteins for steroidogenic acute regulatory protein (StAR), cholesterol side-chain cleavage enzyme (P450scc), 3β hydroxysteroid dehydrogenase type 2 (3β HSD), 17α-hydroxylase/17,20-lyase/17,20-desmolase (P450 17OH), steroid 21-hydroxylase (P450 21OH), steroid 11-β-hydroxylase type 1 (P450 11βOH), and steroidogenic factor 1 (SF-1), a nuclear factor that increases StAR and steroidogenic enzymes (SEs) expression. Similarly, IL-6 (10 pg/mL) increased the relative expression of proteins and mRNAs for StAR, P450scc, 3β HSD, P450 17OH, P450 21 OH, P450 11βOH, and SF-1 in a time-dependent manner (30 min, P < 0.05 vs control; 60, 120, and 240 min, P < 0.01 vs control). In contrast, IL-6 decreased in a concentration-dependent (P < 0.01 vs control for 1, 10, and 100 pg IL-6/mL) and time-dependent (P < 0.05 vs control for 30, 60,120, and 240 min of 10 pg IL-6/mL) manner the relative expression of the mRNA and protein for adrenal hypoplasia congenita-like protein (DAX-1), a nuclear factor that decreases expression of StAR and SEs. Incubation (1 h) of ZF with 100-nM ACTH increased (P < 0.05 vs control) the relative expression of StAR, P450scc, 3β HSD, P450 17OH, P450 21OH, P450 11βOH, and SF-1 and decreased (P < 0.01 vs control) the relative expression of DAX-1. Murine IL-6 (10 pg/mL) augmented (P < 0.05 vs ACTH) both the stimulatory and inhibitory effects of ACTH. Bovine IL-6 (100 pg/mL, 1-h incubation) also increased (P < 0.01 vs control) the relative expression of the proteins for StAR, P450scc, and SF-1 and decreased (P < 0.01 vs control) the relative expression of DAX-1. In summary, IL-6 increased ZF expression of StAR and 5 SEs, which may be mediated in part by decreasing DAX-1 expression and increasing SF-1 expression.

Abstract
Interleukin-6 (IL-6) is secreted by adrenocortical cells and modifies cortisol secretion. In this study, the effects of IL-6 on adrenal androgen release were investigated. The zona reticularis (ZR) was generally isolated from bovine adrenal glands by dissection. In select experiments, the intact adrenal cortex (ie, all 3 adrenocortical zones) was dissected from the adrenal glands. For androgen release experiments, ZR and intact adrenocortical cubes were dispersed into isolated cells, the cells cultured and exposed to IL-6 and/or adrenocorticotropic hormone (ACTH), and androgen release determined by radioimmunoassay. Basal and ACTH-stimulated androgen release from the ZR was inhibited by IL-6 in a concentration-dependent (10-1000 pg/mL) and time-dependent (4-24 h) manner (P < 0.01 by 1-way analysis of variance and the Bonferroni test). In contrast, IL-6 increased basal and ACTH-stimulated androgen release from mixed adrenocortical cells (P < 0.01). The mechanism of IL-6 inhibition of androgen release was investigated by exposing ZR strips to IL-6 and measuring the expression of the messenger RNA (mRNA) and protein of steroidogenic factors. Basal and ACTH-stimulated expression of the mRNA and protein for steroidogenic acute regulatory protein, cholesterol side chain cleavage enzyme, 3-β-hydroxysteroid dehydrogenase type 2, steroid 17-α-hydroxylase/17,20 lyase/17,20 desmolase, and the nuclear factor steroidogenic factor 1 (SF-1), that stimulates steroidogenesis, were decreased by IL-6 (P < 0.01). In contrast IL-6 increased the mRNA and protein for dosage-sensitive sex reversal, adrenal hypoplasia critical region, on chromosome X, gene 1 (DAX-1), a nuclear factor that inhibits steroidogenesis (P < 0.01). In summary, IL-6 decreased androgen release and the expression of steroidogenic factors in the ZR, and this decrease may be mediated in part through increasing DAX-1 and decreasing SF-1.

Abstract
Locoweeds cause significant livestock poisoning and economic loss in the western United States. The toxicity of Embellisia sp. fungi isolated from locoweed was compared with locoweed toxicity using the rat as a model. Rats were fed diets containing locoweed, fungus and alfalfa, or alfalfa. Locoweed- and fungus-fed rats consumed swainsonine-containing food at approximately 1.3 mg x kg(-1) x d(-1), gained less weight (P = 0.001) and ate less than controls. Swainsonine is the principal agent responsible for inducing locoism in animals. The concentrations of alkaline phosphatase and aspartate aminotransferase enzymes were greater (P < 0.05) in serum of locoweed- and fungus-fed rats compared with control rats. Similar intracellular vacuolation was observed in renal, pancreatic, and hepatic tissues of rats that consumed either locoweed or fungus. Rats that ate locoweed or Embellisia fungi displayed indistinguishable toxicity symptoms. The Embellisia fungi from locoweed can induce toxicity without the plants. Locoism management strategies need to involve management of the Embellisia fungi.

Abstract
The subacute dose-response effects of swainsonine (SW) consumption on immunocompetence and serum constituents of sheep in a nutrient-restricted state were investigated. Sheep (23 wethers, 5 ewes) were assigned to 1 of 5 SW treatments (0, 0.2, 0.4, 0.8, or 1.6 mg swainsonine/ kg bw/d). Swainsonine was delivered by feeding locoweed (Oxytropis sericea) with grama grass and alfalfa hays for a 28-d treatment period followed by a 21-d recovery period without locoweed. Body weights were measured weekly and behavioral changes were monitored for clinical signs of SW toxicity. Venous blood was collected weekly for lymphoblastogenesis and serum constituent analyses. Clinical signs (sluggishness, decreased responsiveness) of swainsonine toxicity were observed from d 14 to 35 in the 0.8 and 1.6 mg treatments. Subacute oral exposure did not appear to affect lymphoblastogenic analyses. Acute and subacute alterations in various serum constituents did indicate subclinical effects of SW ingestion. Linear, quadratic and cubic dose-response relationships were detected for some serum constituents (e.g., alkaline phosphatase, aspartate aminotransferase). Subacute SW consumption at the levels investigated does not seem to affect the immunocompetence of nutrient restricted sheep. The lack of change in serum alkaline phosphatase at the 0.2 mg SW/kg bw/d dose indicates the potential for a no adverse effect level of SW consumption in nutrient restricted sheep. In combination with measurable SW in serum, rises in serum alkaline phosphatase and aspartate aminotransferase activities, and declines in serum Fe and cholesterol during subacute exposure to SW establish these markers as potential indicators of subclinical SW toxicosis.

Abstract
OBJECTIVE The purpose of this study was to determine treatment times at a community hospital that does not receive prehospital electrocardiogram (ECG) transmission and to determine the effect of time to first hospital ECG on overall door-to-drug time. DESIGN Descriptive. SETTING 238-bed Regional Medical Center in Burlington, North Carolina. SAMPLE One hundred four patients with a final diagnosis of acute myocardial infarction were included in this 16-month study. RESULTS A median door-to-ECG time of 5 minutes was within the American College of Cardiology/American Heart Association recommendation of 10 minutes. Shorter treatment times to obtain the first ECG and initiate thrombolytic therapy were associated with younger patients and those arriving by ambulance. CONCLUSIONS While efficiency in obtaining a first hospital ECG on patients with suspected acute myocardial infarctions was achieved, this did not result in low door-to-drug times. Further streamlining of protocol and the exploration of prehospital initiatives may result in a significant reduction in door-to-drug times.

Abstract
Health values, behaviors, and status are shaped by place of residence, region, race, and socio-economic status, among other social factors. Consequently, this article examines barriers to preventive health services for lower-income blacks in five rural counties in Georgia. Qualitative and quantitative data were collected through 281 household, 51 community leader, and six focus group interviews. Female respondents who had been pregnant were most likely to have received pregnancy-related services and all respondents least likely to have received vision and dental screenings. Six of the seven types of services inquired about were most likely to have been received in a private practice setting. Primary barriers to preventive service utilization included ability to pay, perception of need, service availability, accessibility of services, and the perception of racism. The relationship between structural and nonstructural barriers, their impact on preventive service utilization, and research recommendations also were developed and presented.

Abstract
BACKGROUND Staff development experts in a tertiary-care hospital were searching for a holistic approach to facilitating improved outcomes. METHOD Staff development experts, clinical nurse specialists, and clinical managers developed a model that provides a framework for educators to integrate their energies with those of other leaders in order to create a holistic approach to the goal of achieving excellence. RESULTS The model that is proposed links strategies for change with outcome evaluation. CONCLUSIONS The model provides a conceptual lens that helps nurse leaders focus on organizational assessment, strategies to improve the work environment, and the evaluation of outcomes. The model is useful for guiding practice as well as research.

Abstract
The JB6 mouse epidermal cell system has been used extensively as an in vitro transformation model for the study of tumor promotion. The standard JB6 cell assay for promotion of transformation is carried out in soft agar or other anchorage independent conditions. The present study was directed to the development of an in vivo model to distinguish the promotion resistant (P-) and promotion sensitive (P+) progression phenotypes. Results indicate that the grafting assay distinguishes P- and P+ cells in vivo with P+ but not P- cells forming tumors within 7-9 weeks. Expression of dominant negative mutant jun TAM67 blocks both anchorage independent transformation response and graft bed tumor formation by P+ cells, suggesting that the requirement for AP-1 activation in transformation now applies in vivo. Expression of mutated p53 produced a gain of P+ phenotype in P- cells in vitro, but not in vivo. Histochemical and Northern blot analysis for expression of various keratinocyte markers revealed no evidence for expression, suggesting a loss of keratinocyte markers following establishment in culture. In summary, the skin-grafting assay described in this study appears to be a valid in vivo assay for distinguishing the preneoplastic progression phenotypes represented by JB6 P- and P+ cells.

Abstract
The objective of the present study was to determine whether the brain kallikrein-kinin system differs between spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto rats (WKY) and if so, whether any detected differences occur before the development of hypertension in SHR. We measured cerebrospinal fluid levels of various components of the system in adult and young prehypertensive SHR and WKY. Cerebrospinal fluid kinin concentration and appearance rate were higher in SHR. Cerebrospinal fluid active kallikrein level and kininogenase activity were also higher in adult SHR. In addition, cerebrospinal fluid kinin concentration and appearance rate were higher in prehypertensive, 5- to 6-week-old SHR compared with age-matched WKY. However, no differences in cerebrospinal fluid kallikrein or kininogenase activity were observed between the two strains of young rats. Cerebrospinal fluid kinin concentration was higher in young versus adult rats of the same strain. In WKY, cerebrospinal fluid kallikrein also decreased with age although cerebrospinal fluid kallikrein concentration did not decrease in young and adult SHR. Together, these data suggest that there is a hyperactive kallikrein-kinin system in the brain of SHR that may contribute to the hypertensive state in this animal model.

Abstract
Seventy patients undergoing aortocoronary bypass grafting were randomized, double-blind, to receive either atenolol or placebo. There were 35 patients in each group. Patients received either atenolol 5 mg intravenously or matching placebo within 3 h of the completion of surgery. A second intravenous dose was administered 24 h following the first and then atenolol 50 mg orally or matching placebo was given for six days. Continuous Holter monitor recordings were obtained for the 24 h immediately preoperatively and continuously for eight days postoperatively. No patient received any antiarrhythmic drug preoperatively. Patients who required pharmacological intervention for the management of postoperative arrhythmias were withdrawn as treatment failures. Holter monitor analysis continued for 24 h following withdrawal of a treatment failure. All patients were analyzed according to the intention-to-treat principle. Both groups were comparable with respect to age, sex, severity of coronary artery disease, left ventricular ejection fraction, preoperative use of beta-blockers, bypass time, aortic cross-clamp time, number of grafts per patient and frequency of preoperative arrhythmias. Arrhythmia analysis was done manually. Supraventricular arrhythmias (atrial tachycardia, atrial fibrillation and atrial flutter) were classified as either mild (less than 0.5 mins, less than 140 beats/min), moderate (0.5 to 30 mins, 140 to 180 beats/min), or severe (longer than 30 mins, more than 180 beats/min). Ventricular arrhythmia analysis was performed with respect to isolated PVCs, couplets, triplets and episodes of nonsustained ventricular tachycardia.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Studies of the mutagenic action required for specific chemicals to produce benign or malignant tumours suggest that in mouse skin at least two genetic events occur before carcinoma formation. The isolation of an activated form of the c-rasH gene from skin papillomas has provided evidence that this gene may be a target for the first mutation, which could constitute the initiating mutation in skin carcinogenesis. In vitro studies indicate that the v-rasH gene of Harvey murine sarcoma virus (Ha-MSV), a replication-defective transforming retrovirus, could impart a conditional initiated phenotype on cultured keratinocytes by blocking their ability to differentiate terminally and arresting them in a late basal cell stage of maturation. We now show that when the Ha-MSV v-rasH gene is introduced into cultured keratinocytes by a defective retroviral vector, skin grafts constructed with cells carrying the mutated ras oncogene produce papillomas on athymic nude mouse recipients. Furthermore, the expression of the exogenous oncogene seems to be regulated at the transcriptional level in the differentiated portions of the benign tumour.
