Abstract
We have developed a multislice protocol for quantitative T1 measurements in which the processing time and the acquisition time are under 2 minutes each for a complete brain study of 15 slices. An echoplanar, inversion-recovery image sequence is designed to collect data suitable for analysis using a linear regression algorithm. The precision is approximately twice the noise to signal ratio of the images. The accuracy of the protocol is better than 1% for T1 in the range 0-2 seconds and deviates slightly for longer T1 values. The protocol is insensitive to B1 field values. If needed, the data can be postprocessed using a slow, nonlinear algorithm to give an accuracy of less than 1% and a precision of approximately the noise to signal ratio throughout a range of T1 values from 0 to 4 seconds.

Abstract
The clinical presentation of menopause can resemble the symptoms of a mood disorder. We describe the case of a 31-yr-old student helicopter pilot who presented to the Aviation Psychiatry Department with a several-month history of inconsistent training performance, mood lability, tearfulness, anxiety, insomnia, fatigue, and decreased concentration. Symptoms persisted despite stress management training and resolution of family stressors, and further evaluation revealed other symptoms consistent with early menopause. Symptoms responded to estrogen/progesterone therapy, and patient returned to flight training. The clinical presentation, differential diagnosis, treatment, and aeromedical disposition of perimenopause and menopause are discussed.

Abstract
Two meta-analyses have suggested that the addition of an anthracycline to platinum-based chemotherapy may improve survival in advanced ovarian cancer, and two randomised trials have demonstrated superiority of paclitaxel over cyclophosphamide in platinum combinations. A combination of platinum, anthracycline and paclitaxel would, therefore, be a reasonable experimental arm of any future randomised trial in patients with epithelial ovarian carcinoma (EOC). Patients who required chemotherapy for EOC but were ineligible for standard trials or had other gynaecological tumours that required similar platinum-based chemotherapy were considered for this pilot. The platinum/anthracycline/paclitaxel regimen (G-CAT) was given 3-weekly and consisted of doxorubicin 50 mg/m(2) or epirubicin 60 mg/m(2) intravenously (i.v.) bolus, paclitaxel 175 mg/m(2) (i.v.) over 3 h and either cisplatin 75 mg/m(2) (i.v.) or carboplatin AUC 6, with granulocyte colony-stimulating factor (G-CSF) at the neutrophil nadir. Different combinations were used in order to determine the least toxic regimen. Toxicity and response were assessed according to CTC and WHO criteria, respectively. 26 patients entered the study, 13 with EOC and 13 with other gynaecological cancers (peritoneal, fallopian tube, mixed Mullerian). Median age was 49 years (range: 27-67). 8 patients received carboplatin/doxorubicin/paclitaxel, 8 cisplatin/doxorubicin/paclitaxel and 10 carboplatin/epirubicin/paclitaxel. A total of 135 cycles of chemotherapy were delivered, with a median of 6 cycles per patient (range: 2-6). 54 (40%) cycles required G-CSF support and 17 (65%) patients required at least one dose reduction. All patients experienced grade 4 neutropenia and 13 (50%) patients developed grade 3-4 thrombocytopenia (12 of whom had received carboplatin). There were 4 (15%) patients with grade 3/4 infections but no septic deaths. Non-haematological toxicities were manageable, lethargy occurred in 75% of cisplatin-treated patients. Grade 1/2 cardiotoxicity, as assessed pre- and post-treatment by left ventricular ejection fraction, was observed in 6/13 (46%) patients who had received doxorubicin and 2/7 (29%) epirubicin-treated patients. No clinically detectable cardiac toxicity was encountered. The response rate in 25 evaluable patients was 76% (12 CR, 7 PR). Dose intensity was highest in the carboplatin/epirubicin/paclitaxel combination. G-CAT shows high activity and can be administered safely, but only very fit patients are suitable for this regimen as it is associated with considerable toxicity. Carboplatin/epirubicin/paclitaxel was the best tolerated regimen overall.

Abstract
A group of 103 subjects with a strict diagnosis of autism were tested for deletion of band q11.2 on the long arm of chromosome 22. No deletions were found, indicating that when a patient has been diagnosed with autism using strict and consistent criteria, in the absence of other indications, it is unlikely that this individual will have a 22q11 deletion. Testing for 22q11 deletions is therefore unlikely to be necessary in these patients. Am. J. Med. Genet. (Neuropsychiatr. Genet.) 96:15-17, 2000.

Abstract
The ABA-1 protein of Ascaris lumbricoides (of humans) and Ascaris suum (of pigs) is abundant in the pseudocoelomic fluid of the parasites and also appears to be released by the tissue-parasitic larvae and the adult stages. The genes encoding the polyprotein precursor of ABA-1 (aba-1) were found to be arranged similarly in the two taxa, comprising tandemly repeating units encoding a large polyprotein which is cleaved to yield polypeptides of approximately 15 kDa which fall into 2 distinct classes, types A and B. The polyprotein possibly comprises only 10 units. The aba-1 gene of A. lumbricoides is polymorphic, and the majority of substitutions observed occur in or near predicted loop regions in the encoded proteins. mRNA for ABA-1 is present in infective larvae within the egg, and in all parasitic stages, but was not detectable in unembryonated eggs. ABA-1 mRNA was confined to the gut of adult parasites, and not in body wall or reproductive tissues. Recombinant protein representing a single A-type unit for the A. lumbricoides aba-1 gene was produced and found to bind retinol (Vitamin A) and a range of fatty acids, including the pharmacologically active lipids lysophosphatidic acid, lysoplatelet activating factor, and there was also evidence of binding to leukotrienes. It failed to bind to any of the anthelmintics screened. Differential Scanning Calorimetry showed that the recombinant protein was highly stable, and unfolded in a single transition at 90.4 degrees C. Analysis of the transition indicated that the protein occurs as a dimer and that the dimer dissociates simultaneously with the unfolding of the monomer units.

Abstract
Research has demonstrated a relationship between the number of previous alcohol detoxifications and increased severity of the alcohol withdrawal syndrome (AWS) that is hypothesized to be similar to an electrophysiologic "kindling process." Application of a "kindling" model to AWS suggests that neuroadaptation of the central nervous system to repeated detoxifications may also cause neurobehavioral alterations that may affect "craving." This study examined craving as assessed by the Obsessive Compulsive Drinking Scale (OCDS) in 67 adult outpatients meeting DSM-IV criteria (American Psychiatric Association, 1994) for alcohol dependence and AWS having either < 2 and > or = 2 previous detoxifications. Results of ANCOVA revealed that patients with > or = 2 previous detoxifications had higher scores on a scale that measures obsessive thoughts about alcohol, drinking urges and behaviors, and a composite of these scores after controlling for alcohol dependence severity, depressive symptoms and number of drinks 2 weeks prior to the study. Findings emphasize the need to address craving and other psychological variables with respect to treatment of AWS.

Abstract
BACKGROUND Endometriosis is a major women's health-care problem. It causes pain and/or infertility, and affects millions of women worldwide. Endometriosis is defined according to histological criteria by the presence of tissue resembling endometrium in sites outside the uterus, most commonly the ovaries and peritoneum. The aim of treatment has been to remove the deposits of ectopic endometrium that are thought to be responsible for the symptoms of endometriosis. This can be achieved surgically by destroying or removing the implants; medical therapies induce atrophy within the hormonally-dependent ectopic endometrium. The duration of hormonal treatment may be limited by unwanted side effects. There is some evidence, however, from epidemiological research that current use of the combined oral contraceptive pill (OCP) is associated with a reduced incidence of endometriosis. The combined pill has the great advantage over other hormonal treatments that it can be taken indefinitely. OBJECTIVES The aim of this review was to establish the role of modern oral contraceptives in the management of painful symptoms ascribed to endometriosis. SEARCH STRATEGY The search strategy of the Menstrual Disorders Group was utilised to identify all randomised trials of the use of oral contraceptives in the treatment of symptomatic endometriosis. In addition a search of the Cochrane Controlled Trials Register was undertaken together with approaches to pharmaceutical companies. SELECTION CRITERIA All truly randomised controlled trials of the use of oral contraceptive pills in the treatment of women of reproductive age with symptoms ascribed to the diagnosis of endometriosis made visually at a surgical procedure, were included. DATA COLLECTION AND ANALYSIS Study quality assessment and data extraction was carried out independently by two reviewers. One of the assessors was an expert in the content matter. MAIN RESULTS Only one study was identified which satisfied the inclusion criteria. The oral contraceptive used in a conventional manner was less effective than a GnRH analogue in the relief of dysmenorrhoea. No significant difference was noted between the effectiveness of the oral contraceptive pill and a GnRH analogue in the relief of dyspareunia or non-menstrual pain. Headaches and weight gain were more commonly associated with oral contraceptive usage than with GnRH analogue usage whereas hot flushes, insomnia and vaginal dryness were less common. REVIEWER'S CONCLUSIONS There is a paucity of data relating to the use of oral contraceptive preparations in the treatment of symptomtic endometriosis. The data such as it is supports the common practice of the use of the oral contraceptive pill as a first line therapy but further research is required to fully evaluate its role in the management of endometriosis.

Abstract
OBJECTIVE The purpose of this study was to assess the factors associated with acceptance of HIV testing during pregnancy on the part of women receiving prenatal care at public clinics. METHODS Trained interviewers recruited and interviewed 1,357 women receiving prenatal care at clinics in Florida, Connecticut, and New York City. RESULTS Eighty-six percent of participants reported having been tested or having signed a consent form to be tested. Acceptance of testing was found to be related to strong beliefs about the benefits of testing, knowledge about vertical transmission, perceived provider endorsement of testing, and social support. Women who declined testing said they did so because they did not perceive themselves to be at risk for HIV (21%) or they faced administrative difficulties (16%) with some aspect of the testing process (for example, scheduling, limited availability of pre-test counselors). CONCLUSIONS Acceptance rates can be increased when women understand the modes of vertical transmission and the role of medication regimens in preventing transmission; believe that prenatal identification of HIV can promote the health of mother and child; and perceive their providers as strongly endorsing testing. These points can be woven into a brief pre-test counseling message and made a routine component of prenatal care.

Abstract
In recent years, increasing focus has been placed on the relation between environmental qualities and the promotion of well-being. This paper explores this relationship from an environmental psychological approach that emphasizes the broader social and physical context and the central significance of individual goals. In particular, the qualities of home and their potential value in the promotion of well-being are discussed. This paper presents a review of recent literature, followed by an empirical study of homelessness in London. A sample of 531 adults was staying in squats, hotels, hostels, and on the streets. Each setting was examined in terms of qualities of home and a general level of well-being. The results suggest that this sample experienced low levels of well-being, typical of persons experiencing such upheaval. Furthermore, there may be a positive relation between levels of well-being and home-like qualities for some homeless settings. The paper concludes that a focus on qualities of home may contribute to a broader understanding of health and well-being that values individual experience and goals.

Abstract
Sociocultural factors during the postcolonial period have been implicated as paramount in generating conditions that promoted both the origin and subsequent epidemic spread of HIV-1 in Africa. We suggest, however, that the origin of the disease may lie in the interaction between colonial practices (e.g., labor camps, nonsterile vaccination campaigns) and traditional bushmeat hunting in French Equatorial Africa. Both the epidemiology of HIV-2 and the colonial history of West Africa appear more complex, but similar conditions existed there and may have contributed to the origin of HIV-2. Focusing the search for the origins of HIV-1 and HIV-2 on this earlier time period may contribute to understanding the evolution of the HIV viruses and the dynamics of emerging diseases.

Abstract
BACKGROUND In 1994, Oregon implemented the Oregon Health Plan (OHP), extending health care coverage under a system of capitated managed care to uninsured citizens living below the Federal Poverty Level (FPL). We conducted a study to measure receipt of clinical preventive services among women newly enrolled in the OHP. METHODS Six hundred and sixty six women aged 52-64, and living below the FPL in Oregon were randomly selected from OHP enrollment rosters and interviewed by telephone. A follow-up survey was conducted 1 year later. The main outcome of interest was receipt of a screening mammogram during the first year in the OHP. RESULTS At enrollment 17% (65/383) of participants had never had health care coverage. Sixty-six percent of the women (220/333) were overdue for a mammogram. Fifty-five percent (121/220) reported cost as the main reason they had not had this procedure. Mammography rates doubled under the OHP (21% to 52%, 95% CI = 0.25-0.38, p < 0.001). Among women who were overdue for a mammogram at the time they enrolled, an expressed plan to get a mammogram (OR3.0, 95% CI = 1.1-8.7, p = 0.04), citing cost as the main reason for being overdue (OR3.0, 95% CI = 1.3-7.2, p = 0.014), receipt of a routine checkup (OR9.5, 95%CI = 3.7-24.9, p < 0.001), and health care provider's (HCP's) recommendation for mammography (OR8.1,95% CI = 2.9-23.0, p < 0.001) were independently associated with receipt of a mammogram. CONCLUSION The OHP enrolled and successfully delivered clinical preventive services to a medically under served population. Even after removing the financial barrier, obstacles to mammography remain. These may be overcome by health systems changes to insure receipt of routine checkups and appropriate provider recommendations.

Abstract
BACKGROUND This study compared the efficacy of ischemic preconditioning (IPC) and sodium-hydrogen exchanger (NHE)-1 inhibition to reduce infarct size (IS) induced by a 90-minute ischemic insult and examined the interaction between NHE-1 inhibition and IPC. METHODS AND RESULTS In a canine infarct model, either IPC, produced by 1 or four 5-minute coronary artery occlusions, or the specific NHE-1 inhibitor BIIB 513, 0.75 or 3.0 mg/kg, was administered 15 minutes before either a 60- or 90-minute coronary artery occlusion followed by 3 hours of reperfusion. IS was determined by TTC staining and expressed as a percentage of the area at risk (IS/AAR). Although both IPC and BIIB 513 at 0.75 mg/kg produced comparable and significant reductions in IS/AAR in the 60-minute occlusion model, insignificant reductions in IS/AAR were observed in the 90-minute occlusion model. However, BIIB 513 at 3.0 mg/kg markedly reduced IS in both models (P<0.05). Next, to examine the interaction between NHE-1 blockade and IPC, BIIB 0.75 mg/kg was administered either before IPC or during the washout phase of IPC before 90 minutes of coronary artery occlusion. Both combinations resulted in a greater-than-additive reduction in IS/AAR (P<0.05). CONCLUSIONS These data demonstrate that although IPC and NHE-1 inhibition provide comparable protection against 60 minutes of myocardial ischemia, NHE-1 inhibition is more efficacious than IPC at protecting against a 90-minute ischemic insult. Furthermore, the combination of NHE-1 inhibition and IPC produces a greater-than-additive reduction in IS/AAR, suggesting either that NHE activity limits the efficacy of IPC or that different mechanisms are involved in the cardioprotective effect of IPC and NHE-1 inhibition.

Abstract
OBJECTIVE To examine frequency and predictors of severe adverse life events and depressive symptoms among HIV-infected women and a comparison group of uninfected women. DESIGN Analysis of baseline data collected from HIV-infected and uninfected women in a prospective cohort study of HIV infection and women, the HIV Epidemiologic Research Study. METHOD The sample of 871 HIV-infected and 439 demographically and behaviorally similar uninfected women were recruited from four metropolitan areas in the USA. Women provided interview information that included sociodemographic characteristics, sexual and drug-using behaviors, and social and psychological functioning. The outcome measures were number of severe adverse life events (e.g., insufficient money for necessities, physical attack or rape, death of a person close to them) and levels of depressive symptoms. RESULTS HIV-infected and uninfected women reported numerous adverse life events and high levels of depressive symptoms. The two groups, however, did not differ on either outcome measure. Low socio-economic status, injecting drug and crack cocaine use, and high risk sexual activity were related to reports of more adverse events and depressive symptoms for both groups. CONCLUSIONS HIV-infected and uninfected women in socially and economically disadvantaged environments experience many adverse events and high levels of depressive symptoms. HIV infection, at least during the early phase, may be less important than socio-environmental factors in predicting negative psychosocial outcomes for women.

Abstract
Acute promyelocytic leukemia (APL) represents a subtype of acute myeloid leukemia with characteristic morphologic, molecular, and immunophenotypic features. Previous immunophenotypic analyses have shown that leukemic cells in APL typically express the myeloid markers CD33 and CD13 but lack expression of the early hematopoietic progenitor cell antigens CD34 and HLA-DR. We analyzed selected immunophenotypic features of APL by flow cytometry and showed that 7 (41%) of 17 cases contained significant subsets of CD34+ leukemic cells: CD34+ myeloid cells predominated in 2 APL cases. By using a fluorescence-activated cell sorter-fluorescence in situ hybridization approach, we confirmed that the CD34+ cells harbored the t(15;17) translocation characteristic of APL. By using the same experimental approach, CD34+ populations were stratified into primitive CD34+ CD38- and committed CD34+ CD38+ progenitor cell subpopulations; cells in both subsets contained the t(15;17) translocation. The knowledge that APL may be partly or largely CD34+ is important for proper diagnosis. Furthermore, identification of the t(15;17) translocation in CD34+ CD38- blasts indicates that, in at least some cases, the leukemogenic mutation in APL occurs within primitive hematopoietic progenitor cells.

Abstract
Twenty-two chimpanzee hair samples collected from night nests at two different "savanna" sites were analyzed for carbon and nitrogen stable isotope ratios represented as delta13C and delta15N values. The first at Ugalla, Tanzania is a miombo woodland with grass groundcover and small patches of forest. The second at Ishasha, Democratic Republic of the Congo is a habitat composed of riverine gallery forest, semideciduous thicket forest, wooded grassland, and grassland. Based on comparative data from other primates, Ugalla hair delta13C values suggest that the chimpanzees are feeding primarily in the woodland rather than in forest patches or on grassland foods (grasses or grammivorous fauna). Similar comparisons indicate that the Ishasha chimpanzees are feeding within the forests and not in more open areas. In addition, the Ugalla chimpanzees had delta15N values that indicate extensive ingestion of leguminous flowers, seeds, and/or leaves. The Ishasha samples show a range encompassing three trophic levels. Two samples with the most positive values may indicate a nursing signal or vertebrate-feeding. Three individuals with intermediate values are similar to those in omnivorous nonhuman primate species. The four individuals with the lowest values are very similar to those in herbivorous monkeys. Stable isotope ratios permit time-averaged and habitat-specific dietary comparisons among sites, even without habituation or detailed foraging observations.

Abstract
The purpose of this study was to determine the efficacy, engraftment kinetics, effect of bone marrow tumor contamination, and safety of high-dose therapy and granulocyte-colony stimulating factor (G-CSF) mobilized peripheral blood progenitor cell (PBPC) support for patients with responding metastatic breast cancer. Forty two patients underwent G-CSF (10 microg/kg) stimulated PBPC harvest. PBPC and bone marrow aspirates were analyzed by histologic and immunocytochemical methods for tumor contamination. Thirty-seven patients received high-dose therapy consisting of cyclophosphamide 6 g/m2, thiotepa 500 mg/m2, and carboplatin 800 mg/m2 (CTCb) given as an infusion over 4 d followed by PBPC reinfusion and G-CSF (5 microg/kg) support. No transplant related deaths or grade 4 toxicity was recorded. CD34+ cells/kg infused was predictive of neutrophil and platelet recovery. With a median follow-up of 38 months, three year survival was 44% with relapse-free survival of 19%. Histological bone marrow involvement, found in 10 patients, was a negative prognostic factor and was associated with a median relapse-free survival of 3.5 months. Tumor contamination of PBPC by immunohistochemical staining was present in 22.5% of patients and found not to be correlated with decreased survival. G-CSF stimulated PBPC collection followed by a single course of high dose chemotherapy and stem cell infusion with G-CSF stimulated marrow recovery leads to rapid, reliable engraftment with low toxicity and promising outcome in women with responding metastatic breast cancer.

Abstract
The cofactor 6(R)-L-erythro-5,6,7,8-tetrahydrobiopterin (6BH(4)) and its 2 and 4 electron oxidation products 7,8-dihydro-L-biopterin and L-biopterin have been shown to form 1:1 complexes with the thirteen amino acid peptide alpha-melanocyte stimulating hormone (alpha-MSH). Hydrogen bonding to the pyrimidine ring of the cofactor has been established for glu(5) and his(6) of the hormone using Near Infrared Fourier Transform Raman spectroscopy. Binding of these pterins primarily involves the pyrimidine ring, although with the reduced pterins, 7,8-dihydro-L-biopterin and 6BH(4), there is evidence for pi orbital interaction with the pyrazine ring. It is proposed that this pi orbital interaction with the reduced biopterins and alpha-MSH could provide the basis for the observed stability of these pterins to oxidation by either molecular oxygen or photooxidation by UVB (290-320 nm) light. Our results suggest that the formation of the alpha-MSH/6BH(4) complex could play a major role in the control of all 6BH(4) dependent processes.

Abstract
Nuclear receptors (NRs) encompass a superfamily of cytoplasmic/nuclear localized receptors that on ligand binding (or by phosphorylation) directly regulate the transcription of target genes. NRs are involved in many developmental processes, including moulting in insects and dauer larva formation in Caenorhabditis elegans. Here we report the isolation of two genes related to NRs from the filarial nematode Brugia pahangi. Bp-nhr-1 is a member of the NGF1-B subfamily of NRs and is expressed at very low levels in post-infective larval stage 3 (L3) after their transmission to the mammalian host. The second gene, Bp-nhr-2, is related to XR78E/F of Drosophila, a gene involved in the ecdysone response, over the region of its DNA-binding domain. cDNA and genomic clones have been isolated that correspond to Bp-nhr-2. The most striking feature of the encoded protein is that, although there is a DNA-binding domain similar to that of other NRs, the ligand-binding domain is absent. To investigate the pattern of transcription of Bp-nhr-2 in the filarial life cycle, semi-quantitative reverse-transcriptase-mediated PCR was performed; this analysis demonstrated that the gene is expressed in early stages after infection and in the adult and microfilariae, and is up-regulated just before the moult between L3 and L4 but is not expressed during the moult between L4 and adult. Antibodies raised against a peptide corresponding to the transactivation domain of Bp-nhr-2 demonstrate that the protein is expressed in microfilariae and adult samples and that another cross-reactive protein is expressed in these life-cycle stages.
