Abstract
The 2019 Missouri River flood caused billions of dollars in damage to businesses, homes, and public infrastructure. Yet little is known about the farm-level effects of this event and farmers' perceptions of its causes. This study reports on the operational and financial setbacks farmers sustained because of the 2019 floods, as well as on their beliefs on the causes of these floods. It further explores farmers' willingness to pay (WTP) to avoid flood risks and the factors that condition it. The empirical application focuses on a sample of approximately 700 Missouri farmers operating near the Missouri River. Results show that yield loss, loss of growing crops, and inability to plant crops were the three most important consequences of flooding. Nearly 40% of the flood-affected farmers reported financial losses of $100,000 or more. Most respondents identified government decision makers as the cause of the 2019 floods, and many believe that government should prioritize flood control over other benefits (recreation and fish and wildlife habitat) the Missouri River system provides. The WTP results show that less than half of the surveyed farmers were willing to pay to avoid flood risks, with an average WTP estimated at $3 per $10,000 value of agricultural land. Subjective but not objective risk exposure influences WTP for flood risk reduction. Other important determinants of WTP are risk aversion, disutility from flood risks, and respondents' age, income, and education. Directions for policy to improve flood risk management in the Missouri River Basin are discussed.

Abstract
Abstract
Introduction
Non-invasive myocardial work (MW) index incorporates strain by speckle-tracking echocardiography (STE) and individually estimated left ventricular pressure (LVP) curves to calculate the area of the pressure strain loop without the need for invasive LVP measurements. The method was validated in patients without aortic stenosis (AS) where a reference pressure curve is adjusted for individually measured aortic and mitral valve events and the peak LVP is defined by the brachial artery cuff pressure. Before applying this method in patients with AS, potential limitations which can influence the area of the pressure strain loop, such as the LVP curve profile, correct scaling of peak LVP and correct assessment of aortic events must be addressed.
Purpose
The present study aimed to assess the impact of the potential limitations specific to patients with AS and thereby the validity of non-invasive MW index in patients with AS.
Methods
In 20 patients with severe AS we obtained simultaneous LVP, by a micromanometer-tipped catheter, and strain by STE. For each patient, LVP curve estimations were done using three different models: 1. The established LVP reference model based on patients without AS. 2. Enhancement of the established LVP reference model by defining aortic valve opening with diastolic cuff pressure. 3. A new AS specific LVP reference model based on our current invasive measurements. Valvular events were determined by 2D and Doppler echocardiography, and peak LVP estimated as a sum of mean trans-aortic gradient and systolic cuff pressure. Estimated LVP curve tracings were thereafter directly compared with simultaneous invasive measurements (Figure 1). Furthermore, area of the pressure-strain loops using the different estimations of LVP curve were calculated to assess MW and compared to simultaneous invasive measurements for direct comparison.
Results
All three methods had excellent average correlation coefficient between estimated and invasively measured LVP traces. However, estimations with the AS specific reference curve and those enhanced with incorporation of diastolic pressure for aortic valve opening had a higher correlation coefficient (r=0.99, p<0.001) and a more physiological profile during early systole compared to that of the previously validated reference curve (r=0.96, p<0.001) (Figure 1). Furthermore, there was an excellent correlation (r=0.98, p<0.001) and good agreement between MW calculated with all three non-invasive estimation methods and invasive LVP (Figure 2).
Conclusions
The present study is the first to confirm the validity of non-invasive MW in patients with AS. Furthermore, a AS specific reference curve and the enhanced reference curve incorporating diastolic cuff pressure to define aortic valve opening both increased the accuracy of the estimated LVP curve and hence estimation of MW. This could be pivotal when assessing AS patients with marked regional differences such as LBBB or regional ischaemia.

Abstract
Background: Transgender healthcare is a rapidly evolving interdisciplinary field. In the last decade, there has been an unprecedented increase in the number and visibility of transgender and gender diverse (TGD) people seeking support and gender-affirming medical treatment in parallel with a significant rise in the scientific literature in this area. The World Professional Association for Transgender Health (WPATH) is an international, multidisciplinary, professional association whose mission is to promote evidence-based care, education, research, public policy, and respect in transgender health. One of the main functions of WPATH is to promote the highest standards of health care for TGD people through the Standards of Care (SOC). The SOC was initially developed in 1979 and the last version (SOC-7) was published in 2012. In view of the increasing scientific evidence, WPATH commissioned a new version of the Standards of Care, the SOC-8. Aim: The overall goal of SOC-8 is to provide health care professionals (HCPs) with clinical guidance to assist TGD people in accessing safe and effective pathways to achieving lasting personal comfort with their gendered selves with the aim of optimizing their overall physical health, psychological well-being, and self-fulfillment. Methods: The SOC-8 is based on the best available science and expert professional consensus in transgender health. International professionals and stakeholders were selected to serve on the SOC-8 committee. Recommendation statements were developed based on data derived from independent systematic literature reviews, where available, background reviews and expert opinions. Grading of recommendations was based on the available evidence supporting interventions, a discussion of risks and harms, as well as the feasibility and acceptability within different contexts and country settings. Results: A total of 18 chapters were developed as part of the SOC-8. They contain recommendations for health care professionals who provide care and treatment for TGD people. Each of the recommendations is followed by explanatory text with relevant references. General areas related to transgender health are covered in the chapters Terminology, Global Applicability, Population Estimates, and Education. The chapters developed for the diverse population of TGD people include Assessment of Adults, Adolescents, Children, Nonbinary, Eunuchs, and Intersex Individuals, and people living in Institutional Environments. Finally, the chapters related to gender-affirming treatment are Hormone Therapy, Surgery and Postoperative Care, Voice and Communication, Primary Care, Reproductive Health, Sexual Health, and Mental Health. Conclusions: The SOC-8 guidelines are intended to be flexible to meet the diverse health care needs of TGD people globally. While adaptable, they offer standards for promoting optimal health care and guidance for the treatment of people experiencing gender incongruence. As in all previous versions of the SOC, the criteria set forth in this document for gender-affirming medical interventions are clinical guidelines; individual health care professionals and programs may modify these in consultation with the TGD person.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory disease, driven by type 2 inflammation. The condition manifests as moderate-to-severe disease in approximately 20% of adults with AD across Europe, and is associated with a substantial burden on patients, society, and healthcare systems. However, systematic assessments capturing the totality of disease burden associated with moderate-to-severe AD are limited; therefore, the overall impacts of the disease may be underestimated. A systematic literature review was carried out to assess the overall costs of moderate-to-severe AD across Europe, including the financial, societal, and humanistic impacts. PubMed, Embase and Cochrane databases were searched to identify relevant studies published between 1 January 2010 and 2 June 2020. Scientific conference proceedings, health technology assessment websites and patient association group websites were also searched for relevant information. Twenty-seven publications, corresponding to 22 unique studies, were included in the analysis. Total costs (direct and productivity losses) reached €20 695 per-person-per-year (PPPY) for adults with uncontrolled symptoms of moderate-to-severe AD. Direct medical costs ranged between €307 and €6993 PPPY; prescription medications and specialist dermatologist visits were the main contributors. Costs increased with disease severity or with uncontrolled disease. Patients with AD also incurred personal costs of €927 per year for healthcare items not reimbursed, which increased by 9% for those with moderate-to-severe forms. Annual work productivity losses comprised most of the total costs reported for adults with moderate-to-severe AD (up to 60.8% of the total burden) and were highest in those with uncontrolled disease (€13 702 PPPY). Patients with moderate-to-severe disease also experienced physical, emotional, and social impacts. The overall costs of moderate-to-severe AD greatly impact on healthcare systems, patients, and society. Sustained control of moderate-to-severe AD, through effective treatment and care management, is essential to limit the burden caused by the disease.

Abstract
Abstract
Background
Schwannomas are rare tumours that pose a significant management challenge in the abdomen, retroperitoneum and pelvis. No data are available to inform management strategy.
Methods
A collaborative international cohort study, across specialist sarcoma units, was conducted to include adults presenting between 2000 and 2017 with histopathologically confirmed schwannomas within the abdomen, retroperitoneum or pelvis.
Results
Of 485 patients across 12 centres, 38 (7·8 per cent) were discharged without follow-up, 199 (41·0 per cent) underwent early resection and 248 (51·1 per cent) had radiological monitoring. Of these 248 patients, 96 (38·7 per cent) eventually had surgery, giving an overall resection rate of 60·8 per cent (295 of 485). At baseline, median tumour volume was 90·1 (i.q.r. 26·5–262·0) cm3. The estimated growth rate was 10·5 (95 per cent c.i. 9·4 to 11·6) per cent per year, and was consistent in the short term (within 2 years of diagnosis) and long term (beyond 2 years) (ρ = 0·405, P = 0·021). A decision to operate was more common in symptomatic patients (P < 0·001) and for rapidly growing tumours (growth rate more than 20 per cent per year) (P = 0·025). R0/R1 resection was achieved in 91·6 per cent of patients (263 of 287). Kaplan–Meier long-term recurrence rates after R0/R1 resection were 2·3 and 6·7 per cent at 3 and 5 years respectively.
Conclusion
Specific recommendations include: indications for early surgery, prediction of growth from radiological monitoring, promotion of selective submacroscopic resection and cessation of postoperative imaging surveillance.

Abstract
Abstract
Introduction
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is increasingly utilized in young patients. Allo-HSCT usually requires myeloablative therapy that is potentially cardiotoxic. In addition, allo-HSCT survivors have a high prevalence of cardiovascular risk factors.
Purpose
We aim to describe left ventricular systolic function in long term survivors after allo-HSCT.
Methods
This study included 104 patients, aged (mean±SD) 18±10 years at allo-HSCT, and follow-up time was 17±6 years. 74% were sufferers of malignant disease. Pre-transplantation therapies consisted of anthracyclines (AnT) in 44% and mediastinal radiotherapy in 2%. Conditioning regimes consisted of cyclophosphamide with bulsulfsan in 77%. 22% received anti-lymphocyte globulin and 6% received total body irradiation. Left ventricular (LV) function was evaluated by 2D and 3D echocardiography. Healthy controls matched for age, sex and BMI were used in group comparisons. Group comparisons were performed by t-tests and chi-square. A linear regression was used to identify contributing factors to reduced systolic LV function in allo-HSCT survivors.
Results
Most parameters of LV systolic function including 2D and 3D LV ejection fraction (LVEF), global longitudinal strain (GLS), mitral annulus excursion (MAPSE) and s' were all significantly impaired after allo-HSCT as compared to the control group. Significant (p<0.05) contributors to LVEF in the multivariate regression analysis were age, AnT dosage, graft versus host disease (GVHD, occurring in 67%) and hypertension (HT, occurring in 31%).
Allo-HSCT Control p value n 104 55 – Gender (female) 56 (54) 29 (53) 0.89 Age (yr) 35±12 36±11 0.44 BMI (kg/m2) 25±5 24±3 0.57 Fractional Shortening (%) 31±6 32±4 0.26 2D LVEF (%) 55±6 59±3 <0.005 3D LVEF (%) 54±5 58±3 <0.005 MAPSE (mm) 13±2 15±2 <0.005 Mean s' (mm) 81±17 89±17 <0.005 2D GLS (%) −17±2 −20±2 <0.005 Values: mean ± SD or n (%), t-test or chi-square.
Conclusion
LV systolic function is reduced in long term survivors of allo-HSCT. Pre-transplantation AnT, HT and GVHD are significantly associated with increased risk of cardiotoxicity.

Abstract
Cells infected by oncogenic viruses may transform, may develop a latent carrier state, or may be destroyed but understanding of the control of the results of infection is incomplete. Even if cells transform, ultimate development of a tumor may be immunologically controlled. For example, cells of some marmoset species transform after infection with RNA tumor viruses, and animals react to the transformed cells with cell-mediated and humoral immune responses. Both virus specific and cross-reacting cell membrane antigens have been demonstrated. Immune deficiency accelerates tumor growth or causes recurrence of a regressing tumor. In contrast certain simian herpesvirus (Herpesvirus saimiri, HVS and Herpesvirus ateles, HVA), which cause no or minor disease in their natural hosts, induce lymphomas or lymphoblastic leukemias in other primate species. The immune response of the natural host species to HVS is greater than that of animals developing malignancies after experimental infection. HVS and HVA share many properties with Epstein-Barr virus (EBV) of man, including antigens appearing early and late during infection and their related antibody responses but no evidence exists that they induce malignancies in their natural hosts. However, if induction is as infrequent as that with EBV and Burkitt's lymphoma (BL), we have not observed sufficient numbers of squirrel or spider monkeys to have seen a BL-like tumor. Interference with the immune systems of animals carrying HVS or HVA may induce tumor development, and clarify our understanding of the relationships between EBV and BL.

Abstract
Autoantibodies purified from humans catalyse the hydrolysis of the neurotransmitter, vasoactive intestinal peptide (VIP). Evidence that the hydrolysis of VIP is due to antibodies includes: the antibody preparations are free of detectable non-immunoglobulin (non-Ig) contamination; the hydrolytic activity is removed by precipitation with anti-human IgG antibody; human B lymphoblastoid cells transformed with Epstein-Barr virus secrete hydrolytic antibodies in culture; the Fab fragments of the antibodies exhibit VIP hydrolysis; and affinity chromatography on immobilized VIP permits purification of specific antibodies with greatly enriched hydrolytic and binding activities. One of the catalytic antibody preparations hydrolyses the Gln-16-Met-17 bond. Studies with synthetic VIP fragments showed that the epitope recognized by this antibody is formed by VIP(15-28). Important binding interactions are contributed by VIP(22-28), a sequence four residues distant from the scissile bond. Antibodies from a second subject hydrolyse six peptide bonds in VIP, clustered between residues 14 and 22. These bonds link amino acids of different charge, size and hydrophobicity, suggesting that the hydrolytic repertoire of the antibodies is considerable. The antibodies do not hydrolyse peptides unrelated in sequence to VIP. Cleavage of several peptide bonds in VIP by polyclonal antibody preparations may be due to several antibodies, each with a unique cleavage specificity. Alternatively, a single antibody may make catalytically productive contact at multiple peptide bonds in the substrate, because of conformational flexibility of VIP or of the antibody active site. Purified light chains from the catalytic antibodies hydrolysed VIP more rapidly than did intact antibodies. The residues constituting the catalytic site of an antibody may be encoded in germline V-region genes or may arise during maturation of the antibody response.

Abstract
Legionella pneumophila endocarditis is extremely rare. The case of a fit 26 year old man who had previously undergone homograft aortic root replacement is reported. He was admitted with legionella pneumonia during the recent localised outbreak but went on to develop endocarditis. His aortic valve was replaced with a mechanical valve and he made an uneventful recovery. Public health issues and diagnosis in susceptible patients during localised outbreaks are discussed.

Abstract
AIMS To determine the incidence, severity, and clinical course of whiplash associated disorder (WAD) in children aged 4-16 years involved as passengers in car crashes. METHODS Prospective surveillance of all paediatric attendances to three English urban emergency departments after car crashes over an eight month period. An initial structured telephone interview at day 2 after the car crash was performed. This was followed by clinical review of symptomatic patients on day 5 after the crash using the Quebec Task Force criteria for outcome assessment, with subsequent clinical review at 14, 28, and 56 days or until earlier symptom resolution. RESULTS 105 children were identified as having been involved in car crashes as passengers. Forty nine children (47%) experienced symptoms of a WAD. Twenty nine children developed symptoms within 24 hours with the remainder developing symptoms by 48 hours. Forty children experienced a WAD grade 1 and nine children suffered a WAD grade 2 injury. The mean duration of symptoms was 8.8 days (range 3-70, SD 10.7). WAD grade 2 symptoms lasted significantly longer than WAD grade 1 symptoms. CONCLUSIONS The incidence of WAD in children in this series was higher than in other studies. The clinical course was more favourable than that reported for adults.

Abstract
Exposure assessment is one of the key parts of the risk assessment process. Only intake of toxicologically significant amounts can lead to adverse health effects even for a relatively toxic substance. In the case of chemicals in foods this is based on three major aspects: (i) how to determine quantitatively the presence of a chemical in individual foods and diets, including its fate during the processes within the food production chain; (ii) how to determine the consumption patterns of the individual foods containing the relevant chemicals; (iii) how to integrate both the likelihood of consumers eating large amounts of the given foods and of the relevant chemical being present in these foods at high levels. The techniques used for the evaluation of these three aspects have been critically reviewed in this paper to determine those areas where the current approaches provide a solid basis for assessments and those areas where improvements are needed or desirable. For those latter areas, options for improvements are being suggested, including, for example, the development of a pan-European food composition database, activities to understand better effects of processing on individual food chemicals, harmonisation of food consumption survey methods with the option of a regular pan-European survey, evaluation of probabilistic models and the development of models to assess exposure to food allergens. In all three areas, the limitations of the approaches currently used lead to uncertainties which can either cause an over- or underestimation of real intakes and thus risks. Given these imprecisions, risk assessors tend to build in additional uncertainty factors to avoid health-relevant underestimates. This is partly done by using screening methods designed to look for "worst case" situations. Such worse case assumptions lead to intake estimates that are higher than reality. These screening methods are used to screen all those chemicals with a safe intake distribution. For chemicals with a potential risk, more information is needed to allow more refined screening or even the most accurate estimation. More information and more refined methods however, require more resources. The ultimate aims are: (1) to obtain appropriate estimations for the presence and quantity of a given chemical in a food and in the diet in general; (2) to assess the consumption patterns for the foods containing these substances, including especially those parts of the population with high consumption and thus potentially high intakes; and (3) to develop and apply tools to predict reliably the likelihood of high end consumption with the presence of high levels of the relevant substances. It has thus been demonstrated that a tiered approach at all three steps can be helpful to optimise the use of the available resources: if relatively crude tools - designed to provide a "worst case" estimate - do not suggest a toxicologically significant exposure (or a relevant deficit of a particular nutrient) it may not be necessary to use more sophisticated tools. These will be needed if initially high intakes are indicated for at least parts of the population. Existing pragmatic approaches are a first crude step to model food chemical intake. It is recommended to extend, refine and validate this approach in the near future. This has to result in a cost-effective exposure assessment system to be used for existing and potential categories of chemicals. This system of knowledge (with information on sensitivities, accuracy, etc.) will guide future data collection.

Abstract
We have studied 23 children from 13 families with a clinical diagnosis of Aicardi-Goutières syndrome. Affected individuals had developed an early-onset progressive encephalopathy that was characterized by a normal head circumference at birth, basal ganglia calcification, negative viral studies, and abnormalities of cerebrospinal fluid comprising either raised white cell counts and/or raised levels of interferon-alpha. By means of genomewide linkage analysis, a maximum-heterogeneity LOD score of 5.28 was reached at marker D3S3563, with alpha=.48, where alpha is the proportion of families showing linkage. Our data suggest the existence of locus heterogeneity in Aicardi-Goutières syndrome and highlight potential difficulties in the differentiation of this condition from pseudo-TORCH (toxoplasmosis, rubella, cytomegalovirus, and herpes simplex virus types 1 and 2) syndrome.

Abstract
A method is described for the determination of concentrations of the mycotoxin ochratoxin A in dried vine fruits (currants, raisins and sultanas) using acidic methanolic extraction, immunoaffinity chromatography clean-up and HPLC determination. The limit of detection was estimated as 0.2 microgram/kg, and recoveries of 63-77% were achieved at 5 micrograms/kg. HPLC-mass spectrometric confirmation of the identity of ochratoxin was obtained. Ochratoxin A and aflatoxins were determined in 60 samples of retail dried vine fruits purchased in the United Kingdom. Ochratoxin A was found in excess of 0.2 microgram/kg in 19 of 20 currant, 17 of 20 sultana and 17 of 20 raisin samples examined, an overall incidence of 88%. The maximum level found was 53.6 micrograms/kg. No aflatoxin was found in any sample analysed, using a method with a detection limit of 0.2 microgram/kg for each of aflatoxin B1, B2, G1 and G2.

Abstract
Sertoli-Leydig cell tumors (SLCT) are sex cord-stromal tumors which exhibit testicular differentiation.1 They account for less than 0.2% of ovarian neoplasms in total but comprise 4% of ovarian tumors in females under 20 yrs of age.2 The morphological appearance of these tumors varies more widely than that of any other ovarian tumor except for the teratomas. Histologically they are now classified into 5 categories: well-differentiated, intermediately differentiated, poorly differentiated, heterologous and retiform.1 We describe the case of an ovarian Sertoli-Leydig cell tumor with retiform pattern in a 7 yr old girl.

Abstract
To investigate the possible presence of protein-bound mutagens in food an analytical procedure has been devised in which the sample is enzymically hydrolysed, fractionated by HPLC and examined by a modified liquid incubation Ames assay. To validate the method MeIQx was added, as a model compound, to beefburger and a recovery of 82% obtained. The limit of detection for protein-bound mutagens was 1 microgram/kg, expressed as equivalents of MeIQx. No detectable mutagenicity was observed when the procedure was applied to samples of well cooked beefburger, irradiated chicken or mycoprotein.

Abstract
This study was designed to determine conception rates in dairy cows after timed-insemination and simultaneous treatment with gonadotrophin releasing hormone (GnRH) and/or prostaglandin F2 alpha (PGF2alpha). A total of 2352 cows was randomly assigned to six groups. Cows in Groups 1 to 5 were palpated per rectum to determine the presence of a corpus luteum (CL) on the ovary, and blood samples were obtained for the determination of plasma progesterone (P4) concentrations. Cows with a CL and P4 concentrations >1 ng/ml were treated (Day 0) with PGF2alpha (25 mg, i.m.) and were observed for estrus. Cows in estrus prior to 72 hours after treatment (Group 5, n = 106) were bred, but were not treated. Cows not observed in estrus by 72 hours were divided into four remaining groups, were bred between 72 and 80 hours and were assigned as follows: Cows in Group 1 (n = 203) were not treated; Cows in Group 2 (n = 200) were treated with GnRH (100 ug, i.m.); Cows in Group 3 (n = 201) were treated with PGF2alpha (25 mg, i.m.); and cows in Group 4 (n = 202) were treated with both GnRH and PGF2alpha. Cows in Group 6 (n = 1440) were not treated with PGF2alpha on Day 0 and were estrual cows that were bred on days when cows in Groups 1 to 5 were time-inseminated. The percentage of cows in all groups pregnant at 45 to 50 days after one insemination was compared using analysis of variance (P<0.05). The conception rate of cows in Group 2 was significantly higher than that of cows in Groups 1 to 4. There was a significant group-by-season interaction. Cows treated with GnRH during the spring had a higher conception rate than at other times of the year. Conception rates of cows in Groups 1 to 4 that were inseminated during the summer were low and not significantly different from each other. Conception rates of cows in Groups 5 and 6 inseminated during the summer were not significantly different from each other, but were significantly higher than that of cows in Groups 1 to 4 that were inseminated during the summer.

Abstract
A method for the measurement of o-tyrosine in irradiated chicken has been developed. The procedure involves the solvent extraction and removal of free o-tyrosine, which is present in unirradiated tissue, followed by acid hydrolysis of bound o-tyrosine in the proteinaceous residue and measurement of the cleaved residues by HPLC with fluorescence detection. Bound o-tyrosine was not detected above 0.01 mg/kg in unirradiated tissue but was observed, in increasing amounts of up to 5.18 mg/kg, when the tissue was irradiated at doses of between 2.5 and 20 kGy. The precision of the analysis was assessed by duplicate determinations, the agreement between duplicates and their respective means averaged 1.7% as defined by the term [(a-b)/(a+b)] x 100% where a and b are the repeat determination values.

Abstract
We demonstrate the first use of an electrochemiluminescent (ECL) label, [4-(N-succimidyloxycarbonylpropyl)-4'-methyl-2,2'- bipyridine]ruthenium(II) dihexafluorophosphate (Origen label; IGEN Inc.), in DNA probe assays. This label allows rapid (less than 25 min) quantification and detection of polymerase chain reaction (PCR)-amplified products from oncogenes, viruses, and cloned genes. For the PCR, we used labeled oligonucleotide primers complementary to human papiloma virus and the Ha-ras oncogene. These samples were followed by ECL analysis or hybridization with specific, Origen-labeled oligonucleotide probes. These studies demonstrate the speed, specificity, and effectiveness of the new ECL labels, compared with 32P, for nucleic acid probe applications. We describe formats involving conventional methodologies and a new format that requires no wash step, allowing simple and rapid sample analysis. These rapid assays also reduce PCR contamination, by requiring less sample handling. Improvements in ECL detectability are currently under investigation for use in DNA probe assays without amplification.

Abstract
A variety of foods (peas (Pisum sativum), chicken meat, eggs, goat's milk, human milk) enriched with the stable isotope 67Zn were prepared by means of intrinsic- and extrinsic-labelling procedures. They were fed to rats and apparent absorption of 67Zn determined from faecal excretion measurements using thermal ionization mass spectrometry. There were significant differences in the absorption of the extrinsic and intrinsic label which differed in magnitude between the foods tested. The extrinsic 67Zn was less well absorbed in peas, chicken meat, eggs, and human milk than intrinsic 67Zn, but in goat's milk the extrinsic 67Zn was better absorbed than the intrinsic label. These results demonstrate that extrinsically-added stable Zn isotopes do not fully exchange with endogenous Zn in many foods, and illustrate the need for caution when using extrinsic labels for Zn bioavailability studies.

Abstract
Four human RAS-like cDNAs and a mouse genomic DNA fragment were used to define novel mouse Ras-like genes and gene families. Inheritance of DNA restriction fragment length variants associated with these genes in recombinant inbred and backcross mice allowed definition of 12 genetic loci, nine of which were mapped, to chromosomes (Chr) 2, 4, 7, 8, 9, and 17. Two possible clusters of Ras-like and/or G protein genes were identified, on Chrs 9 and 17.

Abstract
Over 170 retail samples of beer have been analysed for N-nitrosodimethylamine (NDMA), apparent total N-nitroso compounds (ATNC) and nitrate. Levels of NDMA ranged from below 0.1 up to 1.2 micrograms/kg with a mean of 0.2 micrograms/kg. ATNC was detected in 42% of the samples in concentrations of up to 569 micrograms (N-NO)/kg. The levels of nitrate ranged from less than 0.2 up to 143 mg/kg with a mean of 16.8 mg/kg. There was no correlation between the amounts of NDMA and ATNC found in the retail beers. Samples taken during the course of fermentation showed that NDMA was unaffected by the bacterial reduction of nitrate which causes ATNC formation. HPLC studies using a photolysis/chemiluminescence detector revealed that the ATNC in beer are highly polar species of as yet unknown identity.

Abstract
The levels of trait anxiety and trait anger were compared for adult clients in residential treatment with primary diagnoses of alcoholism, cannabis dependence, cocaine abuse and opioid dependence. With a sample of 809 clients results suggested each of these groups to have significantly elevated anxiety and anger scores, compared to non-client samples. However, there were no significant differences on either anxiety or anger scores based on drug of choice.

Abstract
The MMPI profiles of 268 clients presenting for residential treatment of cocaine addiction were examined. The results revealed clinically significant elevations on the Pd and Ma scales of this instrument. In addition, elevations approaching clinical significance were found on the D, Pa, and Pt scales. These results are discussed in terms of conducting treatment within the context of an Alcoholics Anonymous/Narcotics Anonymous framework, as well as the implications for relapse prevention planning.

Abstract
The fermented foods yoghurt, bread and cheese were analysed for the presence of apparent total N-nitroso compounds (ATNC) by a group-selective procedure involving direct chemical denitrosation and chemiluminescence detection of the released nitric oxide. The levels of ATNC were below the 20 micrograms(N-NO)/kg detection limit in all 20 yoghurts, 23 of the 24 bread samples and 28 out of 31 different varieties of cheese analysed. ATNC were detected in most of those cheese samples manufactured with added nitrate, including Edam, Gouda and Havarti, in concentrations ranging from 30 to 210 micrograms(N-NO)/kg.

Abstract
The GLC/TEA method for N-nitrosodimethylamine (NDMA) in beer was studied collaboratively by 13 laboratories from 7 countries. Collaborators were asked to analyze a total of 10 randomly labeled samples of beer consisting of the following duplicates: a naturally contaminated commercial beer; a beer extremely low (ca 0.1 ppb) in NDMA; and the low NDMA beer spiked with 0.5, 1.9, and 5.0 ppb NDMA. The pooled repeatability and reproducibility coefficients of variation (CV) for all samples were 17% and 27%, respectively. However, when data from 2 laboratories (outliers) were omitted, the corresponding CV values improved considerably (11% and 15%, respectively). Variance analysis showed the presence of a significant laboratory-sample interaction when all data were used for analysis, but this interaction disappeared when data from the 2 outlying laboratories were excluded. The pooled percent recovery of the overall method (omitting outliers) was 101.4 +/- 3.5. All the laboratories detected NDMA in the low NDMA beer. The method was adopted official first action.
