Abstract
A growing body of evidence indicates that impairment of retinal function precedes the earliest signs of vascular complications. The aim of this study was to follow the development of retinopathy both functionally and morphologically in a rat model of diabetes mellitus. Diabetes was induced in rats by intravenous injection of streptozotocin (STZ). Age-matched rats raised under similar conditions served as control. The electroretinogram (ERG) was recorded in order to assess retinal function. The expression of glial fibrillary acidic protein (GFAP) in Müller cells was used as a cellular marker for retinal damage. The ERG responses of the diabetic rats were reduced in amplitude compared to the responses recorded from the control rats as early as 2 weeks after onset of diabetes. The b-wave was more affected than the a-wave. GFAP expression in the diabetic retina did not differ from that in the control retina during the first 5 weeks of diabetes. GFAP was demonstrated only in astrocytes in the vitreo-retinal border. After 6-7 weeks of diabetes, GFAP expression in the retinas of the diabetic rats was also detected in the endfeet of the Müller cells. With the progression of diabetes, GFAP expression spreads throughout the entire length of the Müller cells. In the retinas from control rats, GFAP expression was limited to astrocytes and was not detected in Müller cells even at 40 weeks of follow-up. The observations indicate that the functional integrity of retinal cells is compromised already at short time intervals after onset of experimental diabetes in rats.

Abstract
BACKGROUND Both AD and normal aging cause brain atrophy, limiting the ability of MRI to distinguish between AD and age-related brain tissue loss. MRS imaging (MRSI) measures the neuronal marker N-acetylaspartate (NAA), which could help assess brain change in AD and aging. OBJECTIVES To determine the effects of AD on concentrations of NAA, and choline- and creatine-containing compounds in different brain regions and to assess the extent NAA in combination with volume measurements by MRI improves discrimination between AD patients and cognitively normal subjects. METHODS Fifty-six patients with AD (mean age: 75.6 +/- 8.0 years) and 54 cognitively normal subjects (mean age: 74.3 +/- 8.1 years) were studied using MRSI and MRI. RESULTS NAA concentration was less in patients with AD compared with healthy subjects by 21% (p < 0.0001) in the medial temporal lobe and by 13% to 18% (p < 0.003) in parietal lobe gray matter (GM), but was not changed significantly in white matter and frontal lobe GM. In addition to lower NAA, AD patients had 29% smaller hippocampi and 11% less cortical GM than healthy subjects. Classification of AD and healthy subjects increased significantly from 89% accuracy using hippocampal volume alone to 95% accuracy using hippocampal volume and NAA together. CONCLUSION In addition to brain atrophy, NAA reductions occur in regions that are predominantly impacted by AD pathology.

Abstract
Core lists of recommended resources have long been used as selection tools for collection development in hospital libraries. However, hospital librarians now rely on the Internet for access to up-to-date information to supplement materials available within their libraries. Many libraries now either maintain a library Web page or provide input for their institution's Web page. The difficulty is determining what sites to include on their page. This article is a basic guide to recommended links for hospital libraries. It is intended as a starting place for hospital librarians who wish to create (or add to) a Web page of good links to be used for answering reference questions, or as a list for library users. The list is available as a link from the Sharp Health Science Library Web page <http://www4.umdnj.edu/chlibweb> where it will be updated at least annually. Links will be checked on a regular basis.

Abstract
Membrane biofouling and tissue changes in the foreign body response are known to cause detrimental reductions of analyte transport into implanted biosensors. The relative contribution of each phenomenon is unknown. Hollow fiber microdialysis probes were employed to assess the effect of subcutaneous implantation on glucose flux through polymeric membranes in rats over 8 days and to differentiate the transport effects of biofouling versus tissue changes. Three commercially available membranes were examined: poly(ether sulfone) (PES), polyacrylonitrile (PAN), and polycarbonate (PC). As measured by glucose recovery (the ratio of microdialysis glucose to blood glucose concentrations), transport through PES membranes was significantly less on day 2 than day 0 (39% decrease, p < 0.05) whereas PAN and PC showed no significant decreases in flux until day 8 (42 and 43%, respectively). Application of a transport model to glucose recovery data obtained before implantation in vivo and after explantation indicated that mass transport resistances originating from biofouling and tissue compartments increased between days 0 and 8. However, on average the biofouling layer adherent to the probe created substantially less resistance to glucose transport (12-24% of total) than did the tissue that surrounded the probe. These results suggested that future material developments for biosensors should be directed at understanding and modifying transport properties of tissues at the implant site.

Abstract
BACKGROUND Younger patients with colorectal cancer (CRC) have long been thought to have a poorer prognosis than older patients. Recent overseas reports, however, have disputed this. The aim of the present study was to conduct a review of data on patients with colorectal cancer collected over a 29-year period at Princess Alexandra Hospital (PAH) to ascertain the outcome of a younger subset of patients at this hospital. METHODS The PAH Colorectal Project records on 2495 patients with malignancies of the colon, rectum and anus who were treated and followed since 1971, were analysed to determine clinical presentation, treatment and outcome. A group of 61 patients with colo-rectal adenocarcinoma was identified who were aged less than 40 years at presentation. Their clinical data were then compared with the larger group of older patients. RESULTS There were 30 male and 31 female patients in the younger group. A positive family history was the most consistent risk factor, present in 34% of patients. Despite this, only one patient out of 61 had been diagnosed as a result of a screening programme. The Australian Clinico-Pathological Stage (ACPS), histology and distribution of tumours corresponded to that of the older patients. The overall 5-year survival among younger patients was 53%. The 5-year survival rates in younger patients were better than that for older patients for ACPS A and B, reaching statistical significance for both of these stages. CONCLUSIONS Our results indicate that younger patients with colorectal cancer have the potential to do just as well as older ones. With the influence of a family history of colorectal cancer being very apparent in this group, greater emphasis should be placed on an adequate screening programme for them.

Abstract
Magnetic resonance (MR) tracking of magnetically labeled stem and progenitor cells is an emerging technology, leading to an urgent need for magnetic probes that can make cells highly magnetic during their normal expansion in culture. We have developed magnetodendrimers as a versatile class of magnetic tags that can efficiently label mammalian cells, including human neural stem cells (NSCs) and mesenchymal stem cells (MSCs), through a nonspecific membrane adsorption process with subsequent intracellular (non-nuclear) localization in endosomes. The superparamagnetic iron oxide nanocomposites have been optimized to exhibit superior magnetic properties and to induce sufficient MR cell contrast at incubated doses as low as 1 microg iron/ml culture medium. When containing between 9 and 14 pg iron/cell, labeled cells exhibit an ex vivo nuclear magnetic resonance (NMR) relaxation rate (1/T2) as high as 24-39 s-1/mM iron. Labeled cells are unaffected in their viability and proliferating capacity, and labeled human NSCs differentiate normally into neurons. Furthermore, we show here that NSC-derived (and LacZ-transfected), magnetically labeled oligodendroglial progenitors can be readily detected in vivo at least as long as six weeks after transplantation, with an excellent correlation between the obtained MR contrast and staining for beta-galactosidase expression. The availability of magnetodendrimers opens up the possibility of MR tracking of a wide variety of (stem) cell transplants.

Abstract
From a screen for genes expressed and required in the Drosophila salivary gland, we identified pasilla (ps), which encodes a set of proteins most similar to human Nova-1 and Nova-2. Nova-1 and Nova-2 are nuclear RNA-binding proteins normally expressed in the CNS where they directly regulate splicing. In patients suffering from paraneoplastic opsoclonus myoclonus ataxia (POMA), Nova-1 and Nova-2 proteins are present as auto-antigens. Consistent with a role in splicing, PS is localized to nuclear puncta. The salivary glands of ps mutants internalize normally and maintain epithelial polarity. However, the mutant salivary glands develop irregularities in overall morphology and have defects in apical secretion. The secretory defects in ps mutants provide a potential mechanism for the loss of motor function observed in POMA patients.

Abstract
OBJECTIVES Depressive symptomatology has been frequently conceptualized as an individual matter, but social contextual models argue that symptom levels are likely to covary in close relationships. The present study investigated correlation between spouses' depressive symptomatology in middle-aged and older married couples, the influence of gender and race/ethnicity in predicting variability in symptom level, and the importance of individual-level covariates (education, health, and age) and couple-level covariates (household income and net worth). METHODS Results were based on secondary analysis of Wave 1 interviews with White, Black, and Mexican American married couples (N = 5,423) from the Health and Retirement Study (HRS) and the Study of Asset and Health Dynamics Among the Oldest Old (AHEAD). Dyadic data from husbands and wives were analyzed with multilevel modeling. RESULTS Husbands' and wives' depressive symptoms were moderately correlated, gender and race/ethnicity (and their interaction) predicted depressive symptoms, and both individual-level and couple-level characteristics were significant covariates. Similarities as well as differences are noted between the HRS and AHEAD results. DISCUSSION Results highlight the importance of dyadic data and multilevel models for understanding depressive symptomatology in married couples. The influence of race/ethnicity merits greater attention in future research. Differences in findings between HRS and AHEAD suggest life-course, cohort, or methodological influences.

Abstract
Fractionation of hypothalamic extracts on a Sephadex G-25 column separates follicle-stimulating hormone-releasing factor (FSHRF) from luteinizing hormone-releasing hormone (LHRH). The FSH-releasing peak contained immunoreactive lamprey gonadotropin-releasing hormone (lGnRH) by radioimmunoassay, and its activity was inactivated by an antiserum specific to lGnRH. The identity of lGnRH-III with FSHRF is supported by studies with over 40 GnRH analogs that revealed that this is the sole analog with preferential FSH-releasing activity. Selective activity appears to require amino acids 5-8 of lGnRH-III. Chicken GnRH-II has slight selective FSH-releasing activity. Using a specific lGnRH-III antiserum, a population of lGnRH-III neurons was visualized in the dorsal and ventral preoptic area with axons projecting to the median eminence in areas shown previously to control FSH secretion based on lesion and stimulation studies. Some lGnRH-III neurons contained only this peptide, others also contained LHRH, and still others contained only LHRH. The differential pulsatile release of FSH and LH and their differential secretion at different times of the estrous cycle may be caused by differential secretion of FSHRF and LHRH. Both FSH and LHRH act by nitric oxide (NO) that generates cyclic guanosine monophosphate. lGnRH-III has very low affinity to the LHRH receptor. Biotinylated lGnRH-III (10(-9) M) labels 80% of FSH gonadotropes and is not displaced by LHRH, providing evidence for the existence of an FSHRF receptor. Leptin has equal potency as LHRH to release gonadotropins by NO. lGnRH-III specifically releases FSH, not only in rats but also in cows.

Abstract
A clinically oriented two-dimensional intensity-modulated beam delivery method is implemented using multiple static segmented fields, i.e., the "step-and-shoot" approach. Starting with a desired al" intensity distribution, it creates a multiple-level intensity approximation, and then constructs a sequence of segmented fields to deliver the multiple-level intensities using multileaf collimator (MLC) and independent backup jaws. The approach starts with a simple grouping of all the nonzero intensity values into a minimum number of clusters for a user specified deviation tolerance for the ideal plan. The k-means clustering algorithm is then employed to find the optimal levels of intensity that minimize the discrepancies between the ideal and the approximated intensities, without violating the user specified deviation tolerance. The multiple-level intensities are then decomposed into a sequence of machine deliverable segments. Apart from the first segment for each gantry angle, all the other segments are arranged to minimize the total travel distance of the leaves. The first segment covers the entire irradiated area and is used for treatment verification by electronic portal imaging. The implementation issues due to the physical constraints of the MLCs are also addressed.

Abstract
An international group of clinical and basic scientists participated in the Frontotemporal Dementia and Pick's Disease Criteria Conference at the National Institutes of Health in Bethesda, Md, on July 7, 2000, to reassess clinical and neuropathological criteria for the diagnosis of frontotemporal dementia (FTD). Previous criteria for FTD have primarily been designed for research purposes. The goal of this meeting was to propose guidelines that would enable clinicians (particularly neurologists, psychiatrists, and neuropsychologists) to recognize patients with FTD and, if appropriate, to expedite their referral to a diagnostic center. In addition, recommendations for the neuropathological criteria of FTD were reviewed, relative to classical neuropathology and modern molecular biology.

Abstract
BACKGROUND Based on the knowledge that Tourette's syndrome (TS) is associated with several clinical features that can impair school function and growing evidence that the disorder is much more common than previously thought, the authors hypothesized that TS and related tic disorders would be associated with school problems in the childhood population at large. METHODS Direct, blinded (to educational placement) interviews of 1,596 schoolchildren in Monroe County, Rochester, NY, were conducted. RESULTS Twenty-seven percent of 341 students classified as receiving special education (SpEd) had tics compared with 19.7% (p = 0.008) of 1,255 students in regular classroom programs (RegEd). The weighted prevalence estimates for tics were 23.4% in SpEd and 18.5% in RegEd. A higher percentage of students in SpEd (7.0%) met diagnostic criteria for TS than students in RegEd (3.8%; p = 0.01). CONCLUSIONS Although possibly influenced by selection bias, our results indicate that tic disorders are common in children and are highly associated with school dysfunction. Tics may represent an identifiable sign of an underlying brain developmental disorder that contributes to academic difficulties.

PURPOSE To report a case of probable non-uniting double retinal arterial circulation. METHODS Case report. A 66-year-old man suffered central retinal artery occlusion. RESULTS The medical findings and angiographic workup supported the existence of double central retinal circulation not uniting before entering the globe and independently branching in the retina. CONCLUSIONS In previously recognized unusual anatomic structures of the central retinal artery two parallel arteries were recognized, both of which united before entering the globe. We have described a rare anatomic variant in which those arteries remained separated after entering the globe, including while branching in the retina.

Abstract
PURPOSE To assess whether early hyperbaric oxygenation (HBO) treatment has a beneficial effect on visual results after retinal artery occlusion (RAO). METHODS A comparative retrospective study in which medical records of all HBO-treated RAO patients in our department were reviewed and compared with matched RAO patients not treated by HBO (from a different medical center). Mean visual acuity (VA) at completion of treatment, the presence or absence of improvement in VA between admission and discharge, and the mean change in VA between admission and discharge were noted. All patients treated by HBO had treatment no later than 8 hours after the beginning of visual symptoms. RESULTS Mean VA at discharge was 0.2981 (6/20) in the treated group and 0.1308 (6/46) in the control group (p < 0.03). In the treated group, 82.9% had an improvement in VA between admission and discharge, compared with 29.7% of the control group (p < 0.00001). Mean improvement in VA was 0.1957 in the treated group and 0.0457 in the control group (p < 0.01). Differences in outcome measures between treatment and control groups were found to reflect the difference between treated and untreated hypertensive patients. No difference was found between treated and untreated non-hypertensive patients. CONCLUSIONS Early HBO therapy appears to have a beneficial effect on visual outcome in patients with RAO. Further large-scale prospective controlled studies are needed to confirm this.

METHODS From January 1, 1992, to September 30, 1999, our center performed 18 renal transplants in previous solid organ recipients. During the same period, 815 total renal transplants were performed. One- and 3-year graft and patient survival, recipient demographics, donor type, and reason for transplantation were compared between these groups. RESULTS Of the 18 recipients, 7 had prior heart transplants, 4 had prior liver transplants, and 7 had prior lung transplants. Cyclosporine toxicity contributed to renal failure in 17 (94.4%) of the patients-either as a sole factor (11 patients) or in combination with hypertension, renal artery stenosis, or tacrolimus toxicity (6 patients). Kaplan-Meier 1- and 3-year patient survival was 82.9% and 73.7%, compared with 95.5% and 90.7% in all renal transplant recipients. No surviving patient has suffered renal allograft loss. Mean current creatinine level is 1.4 mg/dL. CONCLUSIONS Renal transplantation is an excellent therapy for ESRF following prior solid organ transplantation. One and 3-year patient and graft survival demonstrate the utility of renal transplantation in this patient population.

Abstract
AIMS The objective of this study was to compare the effects of high doses of ebastine with terfenadine and placebo on QTc. METHODS Thirty-two subjects were randomly assigned to four treatments (ebastine 60 mg x day(-1), ebastine 100 mg x day(-1), terfenadine 360 mg x day(-1), placebo) administered for 7 days. Serial ECGs were performed at baseline and day 7 of each period. QT interval was analysed using both Bazett (QTcB) and Fridericia (QTcF) corrections. RESULTS Ebastine 60 mg (+ 3.7 ms) did not cause a statistically significant change in QTcB compared with placebo (+ 1.4 ms). The mean QTcB for ebastine 100 mg was increased by + 10.3 ms which was significantly greater than placebo but was significantly less (P < 0.05) than with terfenadine 360 mg (+ 18.0 ms). There were no statistically significant differences in QTcF between ebastine 60 mg (-3.2 ms) or ebastine 100 mg (1.5 ms) and placebo (-2.1 ms); although terfenadine caused a 14.1 ms increase which was significantly different from the other three treatments. The increase in QTcB with ebastine most likely resulted from overcorrection of the small drug-induced increase in heart rate. CONCLUSIONS Ebastine at doses up to five times the recommended therapeutic dose did not cause clinically relevant changes in QTc interval.

Abstract
Leber congenital amaurosis (LCArpar; is a heterogeneous disorder representing the congenital forms of retinitis pigmentosa accounting for about 5% of all retinal dystrophies. The RPE65 gene product is required for regeneration of the visual pigment for phototransduction. Defects in the RPE65 gene have so far been shown to account for approximately 10 % of known cases of LCA. Here we describe four additional novel mutations in the RPE65 gene (c.889delA, c.131G>A, c.1249G>C, c.430T>G) and several novel polymorphisms in a large series of LCA patients.

Abstract
Surprisingly little is known about the development of connections within a functional area of the cerebral cortex. We examined the postnatal growth of connections in mouse barrel cortex during the second and third weeks after birth, coinciding with the period of rapid synaptogenesis that occurs just after the barrels first form. A barrel is a group of neurons in layer 4 of somatosensory cortex that is part of a cortical column. Each whisker/barrel column is linked anatomically and functionally to a homotopic whisker on the contralateral face. Radial groups of cortical neurons were labeled with the neuronal tracer biotinylated dextran amine in mice ranging in age from postnatal day 8 (P8; P0 is the date of birth) to adulthood. The spatial distributions of retrogradely labeled neurons in different laminae were analyzed. The barrel map in layer 4 was used as a template to compare quantitative data from different animals and to account for substantial changes in barrel and barrel field size during development. Intrinsic projections 1) innervate increasingly more distant targets within barrel cortex up to 3 weeks of age; 2) continue to form in targets after 3 weeks, effectively strengthening existing connections; 3) follow a timetable for growth that is layer-specific; 4) link more distant barrel columns in layer 4 from neurons that are found preferentially in the barrel side and the septa between barrels; and 5) form over the shortest distances between the barrel columns. These data indicate that intrinsic connections in mouse barrel cortex develop by the progressive addition of neuronal connections rather than by sculpting preliminary connections. We describe statistically significant changes in connectivity during development that may be applied to model and assess the development of connections after a variety of experimental perturbations, such as to the environment and/or the genome.

Abstract
OBJECTIVES Prior studies have conceptualized and operationalized social support in different ways, making it difficult to determine if the inconsistencies in findings are due to differences in study design, samples, conceptualization, or measurement. The present study examined the replicability of models of social support and caregiver distress across 4 community-based caregiving studies representative of many conducted in the past 10 years. The goal was to identify areas of consistency in findings across the data sets. METHODS The authors analyzed 3 models specifying patterns of relationship between social support and depression (main effect, mediation effect, and moderation effect) separately within data sets using hierarchical ordinary least squares regression. Results were compared across data sets. RESULTS The replication analysis confirmed the robustness of behavior problems and caregiver health as important contributors to caregiver distress. Results of hypotheses examining the pattern of relationship between social support and distress were inconsistent, however. Only 1 type of social support was associated with distress in the expected direction: Less emotional support was associated with higher levels of distress in 2 of the 4 data sets. DISCUSSION More complex theoretical models that incorporate common measures to represent the linkages between types of stressor, types of support, and their interactions are needed to foster replicability and generalizability of research results.

Abstract
Cutaneous fungal infections in immunocompromised patients can be aggressive and difficult to treat. To determine the safety and efficacy of oral terbinafine for the treatment of tinea corporis or tinea cruris in subjects with human immunodeficiency virus (HIV) infection or diabetes, 2 prospective, randomized, open-label studies were conducted in general community and referral centers. HIV-positive (n = 6) and diabetic patients (n = 8) between the ages of 18 and 75 years diagnosed with either tinea corporis or tinea cruris, as confirmed by potassium hydroxide (KOH) wet mount microscopy, were randomized to receive either 1 or 2 weeks of the antifungal treatment. Patients received oral terbinafine 250 mg once daily for 1 or 2 weeks. Main outcome measures were mycological cure, determined at week 6 for HIV-positive and diabetic patients. Three subjects were excluded from the efficacy analyses because of negative cultures at screening (n = 2) and lack of follow-up cultures (n = 1). Efficacy results were similar between the 1- and 2-week groups in both studies. All HIV-positive subjects and 83% of diabetic subjects achieved mycological cures at week 6 based on culture results. In a safety population that included all randomized patients (N = 14), no subject experienced adverse events or significant changes in laboratory findings related to study medication. Results of these small series indicate that a short course of oral terbinafine 250 mg once daily is a safe and effective treatment for tinea corporis or tinea cruris in subjects with HIV infection or diabetes.

Abstract
For the first time, the complete functional gene for isoprene synthase has been isolated from poplar (Populus alba x Populus tremula). The gene was quite similar to known limonene and other monoterpene synthases, but was found to specifically catalyze the formation of isoprene from the precursor dimethylallyl diphosphate with only a marginal activity for the formation of the monoterpene limonene from geranyl diphosphate as compared with limonene synthases. Omitting the part of the gene that putatively encoded the signal peptide necessary for transport into the chloroplast led to an enhanced rate of isoprene formation by the recombinant protein.

Abstract
OBJECTIVE To update the 1994 practice parameter for the diagnosis of dementia in the elderly. BACKGROUND The AAN previously published a practice parameter on dementia in 1994. New research and clinical developments warrant an update of some aspects of diagnosis. METHODS Studies published in English from 1985 through 1999 were identified that addressed four questions: 1) Are the current criteria for the diagnosis of dementia reliable? 2) Are the current diagnostic criteria able to establish a diagnosis for the prevalent dementias in the elderly? 3) Do laboratory tests improve the accuracy of the clinical diagnosis of dementing illness? 4) What comorbidities should be evaluated in elderly patients undergoing an initial assessment for dementia? RECOMMENDATIONS Based on evidence in the literature, the following recommendations are made. 1) The DSM-III-R definition of dementia is reliable and should be used (Guideline). 2) The National Institute of Neurologic, Communicative Disorders and Stroke--AD and Related Disorders Association (NINCDS-ADRDA) or the Diagnostic and Statistical Manual, 3rd edition, revised (DSM-IIIR) diagnostic criteria for AD and clinical criteria for Creutzfeldt--Jakob disease (CJD) have sufficient reliability and validity and should be used (Guideline). Diagnostic criteria for vascular dementia, dementia with Lewy bodies, and frontotemporal dementia may be of use in clinical practice (Option) but have imperfect reliability and validity. 3) Structural neuroimaging with either a noncontrast CT or MR scan in the initial evaluation of patients with dementia is appropriate. Because of insufficient data on validity, no other imaging procedure is recommended (Guideline). There are currently no genetic markers recommended for routine diagnostic purposes (Guideline). The CSF 14-3-3 protein is useful for confirming or rejecting the diagnosis of CJD (Guideline). 4) Screening for depression, B(12) deficiency, and hypothyroidism should be performed (Guideline). Screening for syphilis in patients with dementia is not justified unless clinical suspicion for neurosyphilis is present (Guideline). CONCLUSIONS Diagnostic criteria for dementia have improved since the 1994 practice parameter. Further research is needed to improve clinical definitions of dementia and its subtypes, as well as to determine the utility of various instruments of neuroimaging, biomarkers, and genetic testing in increasing diagnostic accuracy.

Abstract
AIMS/HYPOTHESIS To determine if the haptoglobin 2 allele is associated with an increased risk for the development of diabetic nephropathy. METHODS This study included 110 consecutive normotensive subjects with Type I (insulin-dependent) diabetes mellitus and Type II (non-insulin-dependent) diabetes mellitus seen in two outpatient clinics in Israel. Diabetes duration was greater than 10 years for Type I diabetes and more than 5 years for Type II diabetic subjects. Microalbuminuria was defined as urinary protein excretion of 30 to 300 mg/24 h, and macroalbuminuria was defined as urinary protein excretion of greater than 300 mg/24 h. Serum was taken from subjects for haptoglobin typing by gel electrophoresis. RESULTS Of the participating subjects 54 had Type I and 56 had Type II diabetes. None (0/18) of the subjects homozygous for the haptoglobin 1 allele (1-1) showed any sign of diabetic nephropathy, as compared with 34 % (19/55) of subjects homozygous for the haptoglobin 2 allele (2-2) and 27 % (10/37) of heterozygous subjects (2-1) (p < 0.04). Of the subjects 29 showed macroalbuminuria. The risk of developing macroalbuminuria was found to be greater in subjects with two haptoglobin 2 alleles (22 %) (12/55) as compared with one haptoglobin 2 allele (8 %) (3/37) or no haptoglobin 2 alleles (0%) (0/18) (p < 0.03). CONCLUSION/INTERPRETATION By showing a graded risk relation to the number of haptoglobin 2 alleles in Type I and Type II diabetic subjects, these studies further support our hypothesis that the haptoglobin phenotype is a major susceptibility gene for the development of diabetic nephropathy.

Abstract
Recent studies have detected significant elevations of interleukin (IL)-5 mRNA in the liver parenchyma of patients with both primary biliary cirrhosis and acute rejection after liver transplantation. In both of these disorders, intrahepatic biliary epithelial cells (BECs) are the targets of injury. We hypothesized that BECs may themselves express IL-5 receptors that may modulate key biliary functions. RNAs coding for IL-5alpha and -beta receptors were amplified by RT/PCR from a biliary cell line derived from a human cholangiocarcinoma (Mz-ChA-1) and verified by DNA sequencing. IL-5 receptor distribution was detected immunocytochemically on Mz-ChA-1 cells, immortalized murine BEC, bile duct-ligated rat liver, and isolated cholangiocytes. Patch-clamp studies on Mz-ChA-1 cells showed that IL-5 inhibits 5'-N-ethylcarboxamidoadenosine-stimulated chloride currents. Additional functional studies showed that IL-5 inhibits secretin-induced bile flow. We conclude that BECs express IL-5 receptors and that IL-5 modulates BEC chloride currents and fluid secretion. Since IL-5 has previously been associated with cholestatic liver disease, we speculate that IL-5 may contribute to liver injury through its effects on biliary secretion.

Abstract
Elevated plasma homocysteine is an acknowledged risk factor for arteriosclerotic occlusive disease, but little clinical evidence is available regarding its role in acute arterial thrombosis in the absence of an underlying lesion. A 45-year old man presented with an acute abdomen. A magnetic resonance arteriogram (MRA) showed occlusion of the superior mesenteric artery. At exploration, necrotic ileum was resected and the superior mesenteric artery was thrombectomized, restoring normal mesenteric flow. The plasma homocysteine level was 98.8 mmol/L, more than eight times the normal level. No embolic source was identified and an MRA and contrast arteriogram showed no residual occlusive disease in the superior mesenteric artery. Additional studies documented pernicious anemia, which was treated with cobalamin (vitamin B12) injections. This case provides further evidence of an association between hyperhomocysteinemia and acute arterial thrombosis. Hyperhomocysteinemia can result from easily correctible vitamin B12, B6, or dietary folate deficiencies. Plasma homocysteine levels should be determined in young individuals with acute arterial thrombosis whenever a hypercoagulable state is suspected.

Abstract
AIMS To explore the possibility that stable MMP patients have sleep-disordered breathing (SDB) and abnormal sleep architecture defined by nocturnal sleep stages and sleep efficiency. DESIGN Observational. SETTING Regional Methadone Service and sleep disorders laboratory in a university affiliated hospital. Participants and measurements. Ten stable MMP patients and nine normal subjects were assessed clinically and with overnight polysomnography. FINDINGS There were no differences in age, sex and body mass index between the groups. The methadone dose ranged between 50 and 120 mg/day. Six patients had central apnoea index (CAI) greater than 5, four had a CAI greater than 10 and three of these exhibited periodic breathing. No normal subject had central sleep apnoea. The patients had lower sleep efficiency (p < 0.05), less slow wave sleep (p < 0.01), less rapid eye movement sleep (p < 0.05) and more Stage 2 sleep (p < 0.05) than controls. CONCLUSIONS Stable MMP patients have more sleep architecture abnormalities than controls and a higher prevalence of central sleep apnoea. Further studies are needed to confirm these findings, to delineate the mechanisms for the abnormalities and to assess whether the SDB is related to sudden death in stable MMP patients. We recommend that MMP patients have awake and sleep respiration assessed to identify those potentially at risk.

Abstract
Genetically informative longitudinal data on self-reported symptoms of depression allow for an investigation of the causes of stability and change in depression symptoms throughout adult life. In this report, the authors investigated the relative contribution of genetic and environmental influences to symptoms of depression in 83 monozygotic and 84 dizygotic male twin pairs from the National Heart, Lung, and Blood Institute (NHLBI) Twin Study. Participants first completed the Center for Epidemiologic Studies-Depression (CES-D) scale in 1985-1986 and again during 1995-1997. Mean age of twins at baseline was 63 years, range 59 to 70. From cross-sectional genetic analyses we estimated the heritability of CES-D to be 25% (95% confidence interval [CI], 11%-39%) at baseline and 55% (95% CI, 40%-71%) at follow-up. Fitting longitudinal genetic models to the two-wave data, we found that stability of symptoms over the 10-year follow-up was due primarily to continuity of genetic influences.

Abstract
The Functional Status Examination (FSE) is a new measure designed to evaluate change in activities of everyday life as a function of an event or illness, including traumatic brain injury. The measure covers physical, social, and psychological domains. The FSE is based on a structured interview and includes levels of functioning that accommodate the full spectrum of possible outcomes, from death through recovery to preinjury functioning. Based on 133 prospectively studied patients with moderate to severe traumatic brain injury, the FSE has favorable psychometric properties including good test-retest reliability (r = 0.80) and close correspondence of assessments provided by the patient and their significant other (SO; r = 0.80). The FSE correlated significantly with each of three severity indices with closest relationships occurring between the FSE assessed by the SO and posttraumatic amnesia (r = 0.76). The FSE assessed by the SO was significantly (p < 0.05) more closely related to each severity index than the Glasgow Outcome Scale (GOS) or Sickness Impact Profile and, for two of the three indices, than the SF-36. All measures showed significant change from 1 to 6 months after injury with the FSE showing the largest effect sizes. The FSE is significantly related to important constructs such as family burden, SO depression, and sacrifices the family makes, as well as overall indices of recovery and satisfaction with level of functioning. The latter relationships are significantly stronger than for the GOS. The FSE has demonstrated good reliability, validity, and sensitivity, and appears to be a promising instrument for monitoring recovery and assessing functional status in clinical trials.

Abstract
Elliptic flow from nuclear collisions is a hadronic observable sensitive to the early stages of system evolution. We report first results on elliptic flow of charged particles at midrapidity in Au+Au collisions at square root(S)NN = 130 GeV using the STAR Time Projection Chamber at the Relativistic Heavy Ion Collider. The elliptic flow signal, v2, averaged over transverse momentum, reaches values of about 6% for relatively peripheral collisions and decreases for the more central collisions. This can be interpreted as the observation of a higher degree of thermalization than at lower collision energies. Pseudorapidity and transverse momentum dependence of elliptic flow are also presented.

Abstract
Recent reports suggest that selective serotonin reuptake inhibitors (SSRIs) are useful in the treatment of individuals with autism and other pervasive developmental disorders. We report on a single case study of the use of fluvoxamine with a 7-year-old Caucasian girl with severe pervasive developmental disorder. Our findings indicate that fluvoxamine was significantly effective in reducing stereotypical, repetitive behaviors, anxiety, and aggression and in improving prelinguistic and social behaviors. Our results indicate that the use of the SSRIs as a platform for the long-term habilitation of these children should be considered, but further studies are required to establish the efficiency of fluvoxamine for the treatment of children with autism.

Abstract
Interest in the neuropsychology and neuropsychiatry of frontotemporal dementia (FTD) has escalated in the past decade, as evidenced by the accompanying 10 special topic papers from research groups in the UK, France, North America and Australia addressing a wide range of theoretical and clinical issues. The first part of this review deals with the confusing terminologies that have been used in the area and argues for the retention of the term FTD as the general clinical label, with further subcategorization into the three principal clinical syndromes seen at presentation: frontal variant FTD (often called dementia of frontal type), semantic dementia and progressive non-fluent aphasia. Each of these syndromes has a characteristic profile of presenting clinical features, but may be accompanied by any one of five types of non-Alzheimer pathological change. There have also been significant advances in the genetics of FTD with the identification of tau gene mutations on chromosome 17 in some familial cases. The remarkable story of the discovery of these, the tau gene mutations, is briefly described. Part II of this review (Hodges and Miller, 2001) sets the special issue papers within the context of advances in the neuropsychology of frontal variant FTD and semantic dementia.

Abstract
BACKGROUND Chronic idiopathic urticaria (CIU) is the most common type of chronic urticaria, and pruritus is the most prominent symptom. Antihistamines are the first-line treatment for CIU. Sedation and anticholinergic adverse effects are often experienced with the first-generation antihistamines and there is a risk of cardiovascular adverse effects and drug interactions with some second-generation agents. Hence, new treatment options are needed. Desloratadine is a new, potent, nonsedating antihistamine that has an excellent cardiovascular safety profile. METHODS This was a multicenter, randomized, double-blind, placebo-controlled study designed to determine the efficacy and safety of desloratadine in the treatment of moderate-to-severe CIU. A total of 190 patients, aged 12-79 years, with at least a 6-week history of CIU and who were currently experiencing a flare of at least moderate severity, were randomly assigned to therapy with desloratadine 5 mg or placebo once daily for 6 weeks. Twice daily, patients rated the severity of CIU symptoms (pruritus, number of hives, and size of largest hive), as well as the impact of CIU symptoms on sleep and daily activity. Patients and investigators jointly evaluated therapeutic response and overall condition. Safety evaluations included the incidence of treatment-emergent adverse events, discontinuations due to adverse events, and changes from baseline in vital signs, laboratory parameters, and ECG intervals. RESULTS Desloratadine was superior to placebo in controlling pruritus and total symptoms after the first dose and maintained this superiority to the end of the study. Measures of sleep, daily activity, therapeutic response, and global CIU status were also significantly better with desloratadine after the first dose; these clinical benefits were also maintained throughout the 6-week study. No significant adverse events occured. CONCLUSIONS Desloratadine 5 mg daily is a safe and effective treatment for CIU with significant benefits within 24 h and maintained through the treatment period.

Abstract
The second part of this review, which accompanies 10 special topic articles dedicated to frontotemporal dementia (FTD), describes some of the advances in understanding frontal variant FTD (fvFTD) and semantic dementia, and the theoretical insights gained into normal cognitive processes from the study of these syndromes. Recent work has clarified the neuropsychiatric features that distinguish fvFTD from Alzheimer's and has begun to spread light on the underlying deficits in social judgement, theory of mind, processing of emotional stimuli and decision making. With regard to central aspects of cognitive processing, such as memory, patients with fvFTD may have a distinctive profile of performance on tests of explicit and implicit memory, and contrary to current views some patients may even have a severe amnesic syndrome. There is also growing evidence that despite relatively well preserved general language skills, patients with fvFTD have particular problems with verb processing. Although there is agreement regarding the key features of semantic dementia, much controversy has surrounded the issue of whether the cognitive findings favour an explanation in terms of progressive breakdown of a central amodal semantic store or differential involvement of verbal and non-verbal systems. Other topics discussed include the impact of semantic breakdown on phonological processes and episodic memory. We also review recent structural and functional neuroimaging findings in semantic dementia.

Abstract
As the exponential growth of DNA sequence information in databases continues, the task of converting this deposited information into knowledge becomes more dependent on integrative sequence analysis and visualization tools. PANORAMA is an Internet-accessible software package that performs a variety of informatics analyses on a given DNA sequence and returns a visual and interactive representation of the results. Its design is modular, so that further sequence analysis tools can be integrated with minimal effort. The utility of PANORAMA is demonstrated in the analysis of 650 kb of human genomic DNA from chromosome region 3p21.3, a region of potential tumor suppressor genes involved in lung cancer, breast cancer, and other forms of cancer. PANORAMA aided in the discovery of genes and alternate splice forms of known exons, in the demarcation of intron-exon boundaries, and in the identification of promoter regions and polymorphisms, all of which contributed to a better understanding of the region. PANORAMA is available on the World Wide Web at http://atlas.swmed.edu.

Abstract
The genome of the model plant Arabidopsis thaliana has been sequenced by an international collaboration, The Arabidopsis Genome Initiative. Here we report the complete sequence of chromosome 5. This chromosome is 26 megabases long; it is the second largest Arabidopsis chromosome and represents 21% of the sequenced regions of the genome. The sequence of chromosomes 2 and 4 have been reported previously and that of chromosomes 1 and 3, together with an analysis of the complete genome sequence, are reported in this issue. Analysis of the sequence of chromosome 5 yields further insights into centromere structure and the sequence determinants of heterochromatin condensation. The 5,874 genes encoded on chromosome 5 reveal several new functions in plants, and the patterns of gene organization provide insights into the mechanisms and extent of genome evolution in plants.
