Abstract
Alterations in serotonin and norepinephrine neuronal functions have been observed in patients with major depression. Several antidepressants bind to both serotonin transporters and norepinephrine transporters (NET). The ability to image NET in the human brain would be a useful step toward understanding how alterations in NET relate to disease. In this study, we report the synthesis and characterization of a new series of derivatives of iodonisoxetine, a known radioiodinated probe. The most promising, (R)-N-methyl-3-(3-iodopyridin-2-yloxy)-3-phenylpropylamine (PYINXT), displayed a high and saturable binding to NET, with a K(d) value of 0.53+/-0.03 nM. Biodistribution studies of (R)-N-methyl-3-(3-(125)I-pyridin-2-yloxy)-3-phenylpropan-1-amine in rats showed moderate initial brain uptake (0.54% dose/organ at 2 min) with a relatively fast washout from the brain (0.16% dose/organ at 2 h) as compared to [(125)I]INXT. The hypothalamus (a NET-rich region)-to-striatum (a region devoid of NET) ratio was found to be 2.14 at 4 h after intravenous injection. Preliminary results suggest that this improved iodinated ligand, when labeled with (123)I, may be useful for mapping NET-binding sites with single photon emission computed tomography in the living human brain.

Abstract
In the UK, the live birth rate after IVF in women aged less than 36 is >25%. The multiple birth rates in these women are excessive (20% to 25%). The perinatal mortality rate is increased significantly with IVF twins and triplets (8/1000 singletons, 20/1000 twins and 34/1000 triplets). Multiple pregnancies and births significantly increase the risks to the mother and the children, adversely affect family life and are economically disadvantageous to the couple and the wider community. The elective transfer of a single fresh embryo, followed if necessary by a single thawed embryo, in women at high risk of a multiple birth does not reduce the live birth rate and all but prevents the conception of twins and triplets.

Abstract
The major stumbling block for egg donation lies in the recruitment of sufficient suitable donors. This study ascertained the views of egg donors in the UK by analysing 113 completed questionnaires that asked questions about demographics, stimulus to donate, support network available, ethics, the 'process' of donation and payment. Ideas for future recruitment were also sought. The mean age of donors was 31.7 years, and most donors were donating for the first time. Ninety-one per cent of donors were Caucasian and 93% had children of their own. Ninety-six (85%) donors felt fully supported in their decision to become an egg donor and 60 (53%) discussed their donation with their GP. Information regarding egg donation came from many sources. The main motivation to donate was a desire to help childless couples. Many respondents had themselves suffered, or knew of couples with, infertility. Eighty-three (73.5%) respondents felt that expenses alone should be paid to egg donors, and many expressed concerns that large financial incentives may attract the 'wrong women' to donate. Forty-nine (43%) respondents found the procedure painful or stressful in some way, although 95% had no regrets concerning their donation, and 72% would donate again. A common reason for donors not wishing to donate again was age restriction. Respondents were asked their opinion with regard to recruitment and the enthusiasm they expressed needs to be harnessed if the current shortcomings in available donors are to be overcome. Specific recommendations to achieve this are made.

Abstract
BACKGROUND Ovarian failure is a common sequel to chemo/radiotherapy in patients successfully treated for cancer. Harvesting, cryopreserving and subsequently re-implanting ovarian cortical grafts can be used to re-establish reproductive potential in women with cancer. The safety issue, however, is of great concern because residual disease in autografted ovarian tissues might cause recrudescence of disease. METHODS A total of 30 non-obese diabetic severe combined immunodeficient (NOD/LtSz-SCID) mice were individually xenografted s.c. with frozen-thawed ovarian tissue from 18 patients with lymphoma [13 Hodgkin's lymphoma (HL) and 5 non-Hodgkin's lymphoma (NHL)]. The animals were autopsied at 16 weeks, or earlier if cachectic. The xenograft, liver, spleen, sternum, para-aortic lymph nodes and thymus were prepared for histology, immunohistochemistry and human DNA microsatellite analysis. RESULTS None of the animals grafted with ovarian tissue from lymphoma patients developed disease. However, all 3 animals grafted with lymph node tissue from an NHL patient developed B-cell lymphomas that were confirmed as human in origin by DNA microsatellite analysis. CONCLUSION Ovarian tissue harvested before high-dose chemotherapy for HL or NHL may not carry a risk of disease transmission by autotransplantation, although the possibility is difficult to exclude completely.

Abstract
Premature infants are vulnerable to infections, partly because of the low transplacental transfer of maternal antibodies. The present study investigated the placental transfer of maternal rubella-specific antibodies to full-term and preterm infants. The study group consisted of 133 healthy, native Israeli mothers and their 159 newborns. Of these, 69 were full-term infants (gestational age > 37 weeks) of 69 mothers, and 90 were preterm infants (gestational age < 35 weeks) of 64 mothers. Antibody titers against rubella were measured in maternal and umbilical cord blood samples by hemagglutination inhibition and microneutralization techniques. There was no significant difference in the level of protection and in geometrical mean titers by hemagglutination between the full-term and preterm groups. Conversely, significant differences in geometric mean titers of neutralizing antibodies were found between full-term and preterm infants, e.g., 65.9 and 39.8, respectively (P < 0.001). Very low birth weight preterm infants are at greater risk of rubella infection during the first year of life, due to the diminished transfer of neutralizing maternal antibodies. Therefore, earlier vaccination of this group may be beneficial.

Abstract
Long interspersed elements, or LINEs, are retrotransposons that move via an RNA intermediate. In mice, one polymorphic variant of L1 has amplified relatively recently, giving rise to the A-type subfamily in species belonging to the genus and subgenus Mus. Retrotransposition of LINE-1 (L1) requires the function of the L1-encoded reverse transcriptase that is produced from open reading frame 2 (ORF2). Here, we employ a convenient yeast genetic assay to determine the reverse transcriptase activity of the ORF2 obtained from three A-type L1 elements: one, a cDNA from the RNA in ribonucleoprotein particles; another with a purported inactivating mutation; and the third, a hypothetical ancestral construct. Because there are no examples of A-type elements that have transposed recently to inactivate a gene, this assay is the first step towards demonstrating the functional capability of mouse A-type LINE-1 elements. One of the three elements was believed to have been inactivated during evolution by the substitution of leucine for a highly conserved phenylalanine or tryptophan residue among known reverse transcriptases. This mutation did not inactivate the L1 reverse transcriptase in the yeast assay; thus, all three of the elements tested encoded reverse transcriptase activity. We further examined the minimal reverse transcriptase domain within ORF2 by creating a series of deletions. The results demonstrate that removal of the L1 endonuclease domain from the N-terminal region of ORF2 does not affect reverse transcriptase activity as determined by this assay, and that approximately half of the ORF2 coding sequence from mouse A-type L1 elements is required for functional reverse transcriptase.

Abstract
Isolated acute unilateral pleural effusion has twice been reported as the only symptom of ovarian hyperstimulation syndrome (Kingsland et al, 1989; Jewelewicz and Vande Wiele, 1975). The pathogenesis of this disorder is not fully understood and the presence of an isolated pleural effusion lends support to the role of systemic factors rather than purely the transudation of fluid from grossly enlarged ovaries in the progression of this disease. This article describes a second case of an isolated pleural effusion following in-vitro fertilization and embryo transfer.

Abstract
Inhibin (and its alpha-subunit) may be of particular value as a marker for follicular development in in-vitro fertilization (IVF) in comparison with the classic follicle stimulating hormone (FSH)-dependent marker oestradiol in patients following pituitary desensitization and treatment with recombinant FSH (rFSH). This preparation lacks luteinizing hormone (LH), which is essential for thecal cell androgen secretion and thus oestradiol production. Our study has assessed oestradiol and immunoreactive inhibin-like secretion following ovarian stimulation with rFSH or a purified urinary FSH preparation (Metrodin) (uFSH). A randomized, assessor-blind study was initiated using patients receiving a single treatment cycle of IVF (using fresh embryos) following pituitary desensitization with intranasal buserelin (500 microg daily) and the i.m. injection of either rFSH (n = 38) or uFSH (n = 17). Ovarian ultrasound examinations were performed and bloods (10 ml) collected prior to FSH treatment and every 1-2 days until ovulation induction with human chorionic gonadotrophin. LH and FSH concentrations were measured by an immunoradiometric assay, and inhibin-like immunoreactivity by a radioimmunoassay and an enzyme-linked immunosorbent assay, both with alpha-subunit specificity. Oestradiol concentration was measured with a coated tube radioimmunoassay. Following desensitization, basal LH, FSH and oestradiol concentrations were measured, as was that of immunoreactive inhibin. Following treatment with either rFSH or uFSH, LH concentrations remained low while FSH concentrations rose to a plateau of 5.6-6.7 IU/l in both groups. In contrast, the concentration of oestradiol was higher (P < 0.05) with rFSH than with uFSH in the last four days of treatment, a pattern that was repeated for inhibin-like immunoreactivity. The change in oestradiol and inhibin concentrations during treatment was approximately 2-fold higher with rFSH. The total number of follicles obtained with rFSH was similar to that with uFSH. However, the number of follicles with a diameter of >/= 15 mm was higher the rFSH group, and there was a concomitant increase in the number of oocytes recovered. Oestradiol concentration and inhibin-like immunoreactivity (determined by either method) were associated with total follicle number and number of follicles >/= 15 mm in diameter, as well as with each other (P < 0.001). When ovarian hormone output was normalized per follicle produced, oestradiol output was higher for rFSH than for uFSH P = 0.04). Inhibin output was clearly higher using rFSH than uFSH. There were seven pregnancies (one miscarriage) with rFSH and two with uFSH. Despite similar concentrations od FSH in patients, rFSH (Puregon) appears to be more potent in vitro in terms of follicular number, ovarian hormone secretion (both concentration and output/follicle) and oocyte recovery. In both groups, LH concentrations of approximately 1.3 IU/l were sufficient to support oestradiol secretion similar to that normally found in IVF programmes using human menopausal gonadotrophin preparations containing large amounts of LH. Despite known problems of specificity with the assays od inhibin, its measurement was of similar value to oestradiol as a marker of follicular development.

Abstract
A total of 91 children (68 singletons, 20 twins and three triplets) who were conceived from cryopreserved embryos between 27 December 1989 and 18 January 1994, and 83 normally conceived control children (81 singletons and two twins) of a similar age, sex and social class, were assessed for minor congenital anomalies and major congenital malformations. Their development was assessed using the Griffiths Scales of Mental Development. The incidence of minor congenital anomalies (31.9% in the cryopreserved embryo group and 21.7% in the controls) and major congenital malformations (3.3 and 2.4% respectively) in our two groups of children was statistically similar. The relative risk (odds ratio and 95% confidence interval) in the cryopreserved embryo group compared with the controls was 1.7 (0.8, 3.3) for minor congenital anomalies and 1.4 (0.2, 8.5) for major congenital malformations. The minor congenital anomalies were mostly naevi and haemangiomas. The major congenital malformations included Down's syndrome, Beckwith-Wiedemann syndrome and hypophosphataemic rickets in the cryopreserved embryo group and hydronephrosis and gastroschisis in the controls. The Griffiths assessment showed that children from the cryopreserved embryo group and the controls were functioning at a similar level. The mean Griffiths quotient and subquotient values were greater than the standard 100 in children with or without congenital abnormalities. These results in the cryopreserved embryo group are reassuring in that the minor congenital anomaly and major congenital malformation rates were similar to those in normally conceived children of a similar age, sex and social class and their development was not adversely affected by cryopreservation.

Abstract
A cohort of 91 children from cryopreserved embryos and 83 control children who were conceived normally had their development assessed using the Griffiths's scales of mental development. The controls (81 singletons and two twins) of a similar age, sex, and social class were selected from siblings, cousins, and peers of the cryopreserved embryo group (68 singleton, 20 twins, and three triplets). Children from cryopreserved embryos had a lower mean birth weight and mean gestational age and a higher proportion were born by caesarean section. One child from the cryopreserved embryo group had Down's syndrome, three had squints, and four had conductive hearing loss while in the control children, six had squints, and nine had conductive hearing loss. In both groups, including the child with Down's syndrome, the mean Griffiths's quotient was greater than the standard 100. In the children from cryopreserved embryos, the singleton and multiple birth subgroups had statistically similar assessment results. The mean (SD) Griffiths's quotient was 105.69 (13.55) in children from cryopreserved embryos and 108.18 (9.80) in controls at a chronological age of 25.08 (12.86) and 29.19 (14.65) months respectively. Overall, the development in children from cryopreserved embryos did not cause concern though formal testing had highlighted small differences compared with other children conceived normally and of a similar social class.

Abstract
This study examined the psychosocial adjustment of children with asthma compared to children with diabetes, with cancer, and healthy children and the role of functional status in psychosocial adjustment. The total sample included 100 children, aged 8-16 years, (mean = 11.5 years), consisting of 48 boys and 52 girls. Children with asthma scored significantly higher on measures of affective adjustment (depression and internalizing behavior), significantly lower on self-esteem, and evidenced significantly greater functional impairment. Children with cancer missed significantly more school days. After controlling for functional status, no significant differences remained in affective adjustment but absences remained significantly higher for the children with cancer.

1-Benzyl-5,5-diphenyl-2,4-dioxo-3-imidazolidineacetic acid (AC), M(r) = 400.434, triclinic, P1, a = 8.7640 (3), b = 11.112 (1), c = 11.323 (2) A, alpha = 102.10 (2), beta = 95.44 (5), gamma = 109.12 (1)., V = 1002.65 (30) A3, Z = 2, Dx = 1.33 g cm-3, F(000) = 420, mu(Mo K alpha) = 0.852 cm-1, T = 293 K, R = 0.066 for 5551 unique observed reflections. The compound crystallizes from ethanol at room temperature in the form of colourless prism. 3-(2,4-Dichlorobenzyl)-5,5-diphenyl-2,4-dioxo-1-imidazolidineacetic++ + acid (AD), M(r) = 469.323, monoclinic, P2(1), a = 8.0399 (7), b = 9.7237 (6), c = 26.9768 (12) A, beta = 94.281 (4)., V = 2102.92 (96) A3, Z = 4, Dx = 1.48 g cm-3, F(000) = 968, mu(Mo K alpha) = 3.417 cm-1, T = 293 K, R = 0.066 for 5677 unique observed reflections. The compound crystallizes from ethanol at room temperature in the form of colourless prisms. Two approaches are employed in trying to understand the known differences in pharmacological activity: an analysis of the molecular geometries, and electronic structure calculations. A detailed analysis is made of the molecular geometries both from the X-ray diffraction results, and following energy minimization with molecular mechanics. The ab initio calculations employ the energy-minimized conformations. Several electronic properties are intercompared for AC, AD and their common parent molecule diphenylhydantoin (DPH). The analyses of geometry and electronic structure indicate dissimilarities between active and inactive compounds which may be linked to differences in the activity.

Abstract
To determine the effects of fluid restriction in induced labour with oxytocin in 5% dextrose solution, maternal venous blood and fetal cord venous blood were examined in 164 mothers in induced labour and 29 mothers with a spontaneous onset of labour. After satisfactory uterine activity was induced either the oxytocin infusion was managed according to routine delivery unit practice (n = 36), or infusion rates were halved (n = 45), or quartered (n = 43), or discontinued (n = 40). Despite fluid restriction during labour the mean sodium concentration in maternal blood or cord blood had fallen to a similar extent in all four induced groups at delivery. Potassium, urea, creatinine, total protein, and albumin in maternal blood or cord blood were affected differently by induced labour as compared with sodium. The fall in sodium concentration in maternal blood was a more consistent reflection of the total volume of fluid received, mean infusion rates and cord blood sodium after infusion rates were quartered or discontinued. The incidence of hyponatraemia was 5% in mothers and 8% in infants. A comparison of hyponatraemic and normonatraemic cord blood showed no significant differences in serum bilirubin levels or red cell counts, but more hyponatraemic infants developed neonatal jaundice. It is suggested that in induced labour fluid restriction alone does not prevent hyponatraemia and neonatal jaundice.

Abstract
Unilateral asterixis due to a focal brain lesion is a rare occurrence. Acute asterixis restricted to the left upper extremity appeared in a patient in association with signs of acute midbrain dysfunction, without changes in mental status or in the EEG, and in the absence of metabolic or toxic disturbance. Electromyography disclosed features typical of asterixis due to metabolic causes.

Abstract
Percutaneous transhepatic cholangiography with the Chiba University needle has been performed in 42 patients with cholestasis. The examination was successful in 100% of patients with dilated intrahepatic bile ducts and in 89% of those with normal-size ducts. Complications were minimal. The results of this study suggest that PTC with the Chiba needle is superior to the current conventional methods. The patients with intrahepatic cholestasis, which often simulates extrahepatic biliary obstruction, were spared an unnecessary laparotomy.

Abstract
This is a report of 1,079 patients who underwent laparoscopic clip sterlization as of March, 1974. A one-year follow-up was obtained on 977 patients, or 90.5 per cent. Complications due to the clip technique appear limited to postoperative cramps for 24 to 48 hours in 26 per cent of patients. No ectopic pregnancies were detected. Pregnancies, when corrected for unsuspected existing pregnancies and surgical and manufacturing errors, occurred in 2 to 6 cases, for a method failure rate of 2 to 6/1,000. This report documents that experienced laparoscopists can perform this practice with local anesthesia, in combination with first-trimester abortion, and in hospital facilities other than an operating room.

Abstract
In September 1972, clinical trials of a spring-loaded clip for laparoscopic sterilization were begun and extended to a number of centers in the United States and overseas. As of March 1974, more than 1000 patients had undergone the procedure, usually performed under local anesthesia in an outpatient setting, with no fixed contraindications. Complications and pregnancy rates based on a preliminary 6-month follow-up are presented. Complications due to application of the clip appeared to be limited to postoperative cramps lasting 24 to 48 hours (26% of the patients). No ectopic pregnancies were reported. Pregnancies, when corrected for unsuspected pregnancies and misapplication of the clip, occurred in 2 of these first 1000 patients. The difficulties and relative contraindications learned from this unselected series and the advantages over electrocagulation techniques are discussed.
