Abstract
Because of changes in climatic conditions, tree seeds originating from breeding programs may no longer be suited to sites where they are currently sent. As a consequence, new seed zones may have to be delineated. Assisted migration consists of transferring seed sources that match the future climatic conditions to which they are currently adapted. It represents a strategy that could be used to mitigate the potential negative consequences of climate change on forest productivity. Decisions with regard to the choice of the most appropriate seed sources have to rely on appropriate knowledge of morpho-physiological responses of trees. To meet this goal, white spruce (Picea glauca [Moench] Voss) seedlings from eight seed orchards were evaluated during two years in a forest nursery, and at the end of the first growing season on three plantation sites located in different bioclimatic domains in Quebec. The morpho-physiological responses obtained at the end of the second growing season (2+0) in the nursery made it possible to cluster the orchards into three distinct groups. Modeling growth curves of these different groups showed that the height growth of seedlings from the second-generation and southern first-generation seed orchards was significantly higher than that of those from other orchards, by at least 6%. A multiple regression model with three climatic variables (average growing season temperature, average July temperature, length of the growing season) showed that the final height of seedlings (2+0) from the first-generation seed orchards was significantly related to the local climatic conditions at the orchard sites of origin where parental trees from surrounding natural populations were sampled to provide grafts for orchard establishment. Seedling height growth was significantly affected by both seed source origins and planting sites, but the relative ranking of the different seed sources was maintained regardless of reforestation site. This knowledge could be used, in conjunction with transfer models, to refine operational seed transfer rules and select the most suitable sites in an assisted migration strategy.

Abstract
• In this study, we used a canopy photosynthesis model which describes changes in photosynthetic capacity with slow temperature-dependent acclimations. • A flux-partitioning algorithm was applied to fit the photosynthesis model to net ecosystem exchange data for 12 evergreen coniferous forests from northern temperate and boreal regions. • The model accounted for much of the variation in photosynthetic production, with modeling efficiencies (mean > 67%) similar to those of more complex models. The parameter describing the rate of acclimation was larger at the northern sites, leading to a slower acclimation of photosynthesis to temperature. The response of the rates of photosynthesis to air temperature in spring was delayed up to several days at the coldest sites. Overall photosynthesis acclimation processes were slower at colder, northern locations than at warmer, more southern, and more maritime sites. • Consequently, slow changes in photosynthetic capacity were essential to explaining variations of photosynthesis for colder boreal forests (i.e. where acclimation of photosynthesis to temperature was slower), whereas the importance of these processes was minor in warmer conifer evergreen forests.

Abstract
Terrestrial gross primary production (GPP) is the largest global CO(2) flux driving several ecosystem functions. We provide an observation-based estimate of this flux at 123 +/- 8 petagrams of carbon per year (Pg C year(-1)) using eddy covariance flux data and various diagnostic models. Tropical forests and savannahs account for 60%. GPP over 40% of the vegetated land is associated with precipitation. State-of-the-art process-oriented biosphere models used for climate predictions exhibit a large between-model variation of GPP's latitudinal patterns and show higher spatial correlations between GPP and precipitation, suggesting the existence of missing processes or feedback mechanisms which attenuate the vegetation response to climate. Our estimates of spatially distributed GPP and its covariation with climate can help improve coupled climate-carbon cycle process models.

Abstract
In spite of advances made in our understanding of the biology of the hepatitis C virus (HCV), the epidemiology and natural history of HCV infection, and the treatment of chronic hepatitis C, the development and worldwide implementation of a comprehensive prevention and control strategy remains necessary. A World Health Organization informal consultation with the Viral Hepatitis Prevention Board was convened and met in Geneva, Switzerland, 13-14 May 2002, to review epidemiological and public health aspects of HCV infection, and the various prevention and control strategies that are currently in place. Based on the presentations and discussions, a number of specific recommendations were made, which should be considered in conjunction with previously published recommendations.

Abstract
BACKGROUND Hepatitis B virus infection causes substantial morbidity and mortality in the United States. Sexual activity is the most commonly reported risk factor among persons with acute hepatitis B, yet hepatitis B vaccine coverage among adolescents and adults with high-risk sexual practices is low. Sexually transmitted disease (STD) clinics are potentially efficient settings for vaccine administration to persons with high-risk sexual practices; however, little is known about hepatitis B vaccination activities in these settings. GOAL To gain information about policies and activities for vaccinating against hepatitis B in STD clinic settings. STUDY DESIGN In April 1997, a questionnaire was sent to managers of 65 federally funded STD programs in state and local health departments. A similar survey was sent to 89 STD clinic managers in November 1997. RESULTS The response rate among program managers was 97% (63/65). Forty-eight percent considered hepatitis B prevention a program responsibility; 21% had developed and distributed written policies to prevent hepatitis B through vaccination; and 27% had developed policies to encourage hepatitis B education activities. The response rate among clinic managers was 82% (73/89). Forty-five percent reported that their STD clinics had implemented policies recommending hepatitis B vaccination and health education activities. Program managers and clinic managers reported that lack of funding to cover the cost of the vaccine, and lack of resources to provide prevaccination counseling, administer vaccine, and track clients for vaccine series completion were the primary barriers to the implementation of hepatitis B vaccination programs. CONCLUSIONS To enhance hepatitis B vaccination in STD clinics, existing funding sources must be accessed more effectively. Supplemental funding mechanisms for the cost of vaccine and resources for implementing vaccination programs also need to be identified. Additionally, STD clinics and programs should continue to propose and implement hepatitis B vaccination policies.

Abstract
In areas with low hepatitis B virus (HBV) endemicity such as most parts of Europe and the United States "anti-HBc alone" is found in 10-20% of all individuals with HBV markers, i.e., 1-4% of the population. In about 10% of these individuals HBV DNA is detected by PCR, the proportions varying greatly depending on the population studied, being highest in individuals coinfected with hepatitis C virus (HCV) (above 35%) and HIV (above 85%). A small proportion of individuals with "anti-HBc alone" are in the window phase of an HBV infection or in a stage of late HBV immunity. For the large proportion of these individuals this is not the case and they are thought to have an unresolved HBV-infection or a chronic infection in a late or "low grade" productive state. Currently, limited studies have been performed concerning the clinical aspects of individuals with "anti-HBc alone" and suspected chronic HBV infection. The majority of these individuals seem to be healthy. Some chronic carriers with "anti-HBc alone," however, do present signs of chronic hepatitis. Individuals with "anti-HBc alone" are potentially infectious. This is exemplified by a few case reports of HBV transmission to sexual contacts, perinatal transmission between mother and newborns and in blood recipients. Recommendations are given in relation to both the diagnostic and therapeutic procedures in the individuals with "anti-HBc alone" and in the blood banking and transplantation services.

Abstract
To study possible chronic respiratory effects of air pollutants, we initiated a 10-yr prospective cohort study of Southern California children, with a study design focused on four pollutants: ozone, particulate matter, acids, and nitrogen dioxide (NO2). Twelve demographically similar communities were selected on the basis of historic monitoring information to represent extremes of exposure to one or more pollutants. In each community, about 150 public school students in grade 4, 75 in grade 7, and 75 in grade 10 were enrolled through their classrooms. Informed consent and written responses to surveys about students' lifetime residential histories, historic and current health status, residential characteristics, and physical activity were obtained with the help of the parents. In the first testing season, 3,676 students returned questionnaires. We confirmed associations previously reported between respiratory morbidity prevalence and the presence of personal, demographic, and residential risk factors. Rates of respiratory illness were higher for males, those living in houses with pets, pests, mildew, and water damage, those whose parents had asthma, and those living in houses with smokers. Wheeze prevalence was positively associated with levels of both acid (odds ratio [OR] = 1.45; 95% confidence interval [CI], 1.14-1.83) and NO2 (OR = 1.54; 95% CI, 1.08-2.19) in boys. We conclude, based on this cross-sectional assessment of questionnaire responses, that current levels of ambient air pollution in Southern California may be associated with effects on schoolchildren's respiratory morbidity as assessed by questionnaire.

Abstract
To study the possible chronic respiratory effects of air pollutants, we designed and initiated a 10-yr prospective study of Southern California public schoolchildren living in 12 communities with different levels and profiles of air pollution. The design of the study, exposure assessment methods, and survey methods and results related to respiratory symptoms and conditions are described in the accompanying paper. Pulmonary function tests were completed on 3,293 subjects. We evaluated cross-sectionally the effects of air pollution exposures based on data collected in 1986-1990 by existing monitoring stations and data collected by our study team in 1994. Expected relationships were seen between demographic, physical, and other environmental factors and pulmonary function values. When the data were stratified by sex, an association was seen between pollution levels and lower pulmonary function in female subjects, with the associations being stronger for the 1994 exposure data than the 1986-1990 data. After adjustment, PM10, PM2.5, and NO2 were each significantly associated with lower FVC, FEV1, and maximal midexpiratory flow (MMEF); acid vapor with lower FVC, FEV1, peak expiratory flow rate (PEFR), and MMEF; and O3 with lower PEFR and MMEF. Effects were generally larger in those girls spending more time outdoors. Stepwise regression of adjusted pulmonary function values for girls in the 12 communities showed that NO2 was most strongly associated with lower FVC (r = -0.74, p < 0.01), PM2.5 with FEV1 (r = -0.72, p < 0.01), O3 with PEFR (r = -0.75, p < 0.005), and PM2.5 with MMEF (r = -0.80, p < 0.005). There was a statistically significant association between ozone exposure and decreased FVC and FEV1 in girls with asthma. For boys, significant associations were seen between peak O3 exposures and lower FVC and FEV1, but only in those spending more time outdoors. These findings underline the importance of follow-up of this cohort.

RESULTS Overall, 88% of HCWs developed seroprotection. Risk factors associated with failure to develop seroprotection included increasing age, obesity, smoking and male gender (P < .05). Presence of a chronic disease was associated with lack of seroprotection only among persons > or = 40 years of age (P < .05). The two vaccines studied differed in their overall seroprotection rates (90% vs. 86%; P < .05), however, this difference was restricted to persons > or = 40 years of age (87% vs. 81%; P < .01). Among HCWs > or = 40 years of age, the decision analysis found 44 (0.34/100,000 person-years) excess chronic HBV infections over the working life of the cohort associated with use of the less immunogenic vaccine compared to the other. CONCLUSIONS He patitis B vaccines are highly immunogenic, but have decreased immunogenicity associated with increasing age, obesity, smoking, and male gender; and among older adults, the presence of a chronic disease. One of the two available vaccines is more immunogenic among older adults; however, this finding has little clinical or public health importance. Hepatitis B vaccines should be administered to persons at occupational risk for HBV infection early in their career, preferably while they are still in their training.

Abstract
An RNA virus, designated hepatitis G virus (HGV), was identified from the plasma of a patient with chronic hepatitis. Extension from an immunoreactive complementary DNA clone yielded the entire genome (9392 nucleotides) encoding a polyprotein of 2873 amino acids. The virus is closely related to GB virus C (GBV-C) and distantly related to hepatitis C virus, GBV-A, and GBV-B. HGV was associated with acute and chronic hepatitis. Persistent viremia was detected for up to 9 years in patients with hepatitis. The virus is transfusion-transmissible. It has a global distribution and is present within the volunteer blood donor population in the United States.

Abstract
The authors report the first American case of a factor VIII inhibitor found in a patient with Sjögren's syndrome. The inhibitor was isolated from a patient with no known hematologic disorder who was seen with a compartment syndrome of the left thigh after sustaining a fall from bed. The Sjögren's syndrome had been previously diagnosed via lower lip biopsy. After fasciotomy, signs and symptoms of intra-abdominal hemorrhage developed, and the patient was taken to laparotomy, where no hemorrhage was found. A coagulopathy developed, and the patient's hemoglobin continued to fall. A complete factor analysis revealed a factor VIII inhibitor that was quantified at 40 Bethesda units. After vigorous therapy--which included factor concentrates, immunoglobulins, steroids, antifibrinolytic agents, and blood replacement--the patient's bleeding stopped and she continued to convalesce under hospital care until her ultimate death from respiratory problems. Acquired hemophilia with a factor VIII inhibitor may be associated with Sjögren's syndrome.

Abstract
Two hundred and twenty-five infants were randomly assigned to receive 2 micrograms of plasma-derived hepatitis B vaccine (Heptavax) intradermally (ID-2), 10 micrograms intramuscularly (IM-10), or 2 micrograms intramuscularly (IM-2) in the deltoid region at birth, 2 and 4 months. At 6 months, ID-2 infants were less likely to have developed > or = 10 mIU ml-1 of antibody to hepatitis B surface antigen (anti-HBs) than IM-10 infants (91 versus 100%; p = 0.02) and had a lower geometric mean concentration of anti-HBs (312 mIU ml-1 versus 2248 mIU ml-1; p < 0.01). At 6 months IM-10 infants had significantly lower mean weights and lengths than infants receiving 2 micrograms doses of vaccine. Intramuscular administration of 2 micrograms and 10 micrograms doses of Heptavax in the deltoid of young infants was well tolerated and effective; however, intradermal administration of Heptavax provided no immunological benefit over intramuscular administration and resulted in significantly higher rates of induration and persistent hyperpigmentation. Intramuscular immunization at birth, 2 and 4 months is an acceptable, effective alternative schedule for immunizing infants.

Abstract
OBJECTIVES To determine hepatitis B virus (HBV) carrier and infection rates and HBV epidemiology in Honolulu students. DESIGN Cross-sectional survey. SETTING Honolulu public elementary, intermediate, and high schools. PATIENTS A volunteer sample of 4936 students from 43 Honolulu schools. MAIN OUTCOME MEASURES HBV carrier rate (presence of hepatitis B surface antigen) and infection rate (presence of either hepatitis B surface antigen, antibody to hepatitis B surface antigen, antibody to hepatitis B core antigen, or any combinations of these) by school grade, ethnicity, and place of birth. RESULTS Eighty-three (1.68%) students were identified as HBV carriers, and a total of 353 (7.15%) students had serologic evidence of infection. Infection rates increased from elementary school age to high school age, more so in Asian/Pacific Island-born students. The prevalence of infection was higher in Asian/Pacific Island-born students than in those born in the United States. The majority of infected Hawaiian-born students were first-generation Asian/Pacific Island Americans. CONCLUSIONS Horizontal transmission of HBV occurs in Honolulu school-age children. HBV immunization of all infants in Hawaii, not just those born to carrier mothers, is necessary to reduce HBV transmission in Hawaii.

Abstract
A series of synthetic peptides derived from proteins encoded by open reading frames 2 and 3 (ORF2 and ORF3) of the hepatitis E virus was used in an enzyme immunoassay to determine the localization of epitopes in these proteins. Five peptides spanning almost the entire ORF3 protein sequence and 12 peptides from the ORF2 protein were synthesized. Serum samples collected from outbreaks in three different regions of the world (Turkmenistan, Kenya, and Mexico) were analyzed by a peptide-based enzyme immunoassay. Primary analysis of the peptides was accomplished with the use of serum samples obtained from Middle Asia. Four of 5 peptides from the ORF3 protein and 4 of 12 peptides from the ORF2 protein specifically reacted with antibody from sera of HEV-infected patients. Peptides representing immunodominant epitopes were used for the analysis of serum samples from outbreaks in Kenya and Mexico. The data indicate that these synthetic peptides may be used to develop a diagnostic test to detect antibody to the hepatitis E virus.

Abstract
Antibodies to herpes simplex virus type 2 (HSV-2), antibodies to hepatitis B virus (HBV) core antigen (anti-HBc), and VDRL antibodies (serologic evidence of syphilis) were evaluated in women known to be infected with human immunodeficiency virus type 1 (HIV-1) (n = 95) or human T lymphotropic virus type I (HTLV-I) (n = 45) and controls (n = 89). HIV-1-seropositive women were more likely than controls to have antibodies to HSV-2 (88% vs. 54%; P less than .001), anti-HBc (67% vs. 43%; P = .008), and VDRL antibodies (21% vs. 8%; P = .02). Similarly, HTLV-I-seropositive women were more likely than controls to have antibodies to HSV-2 (82% vs. 54%; P = .003) and anti-HBc (67% vs. 43%; P = .008). There was no evidence that HIV-1 or HTLV-I predisposed to chronic hepatitis B virus infection. The stronger associations between HIV-1 and HTLV-I with HSV-2 than the associations with syphilis or HBV are consistent with the hypothesis that recurrent disruptions of mucous membranes caused by HSV-2 infections predispose to sexual transmission of HIV-1 and HTLV-I.

Abstract
To test the effect of ectomycorrhizal fungi (EMF) on interactions between host plants, Pseudotsuga menziesii (Mirb.) Franco and Pinus ponderosa Dougl. ex. Laws., seedlings were grown in replacement series in pasteurized soil with (a) no EMF added, (A) two EMF species added - Rhizopogon vinicolor Smith (specific to Douglas-fir) and R. ochraceorubens Smith (specific to pine), and (c) tour EMF species added - the two Rhizopogon species plus two host generalists, Laccaria laccata (Scop, ex Fr.) Bk. & Br, and Hebeloma crustuliniforme (Bull.) Quel. A replacement series in unpasteurized forest soil also was included. Seedlings without added EMF were colonized by the greenhouse contaminant, Thelephora terrestris. Without added EMF (but with T. terrestris), the tree species mutually inhibited one another, producing Relative Yield Totals significantly < 1; with EMF added, mutual inhibition disappeared. With four EMF species added, Pseudotsuga menziesii seedlings were significantly larger in mixture than in monoculture, with no corresponding decrease in the size of Pinus ponderoso seedlings; this was due solely to seedlings with L. laccata, which apparently enhanced nitrogen (N) and phosphorus (P) uptake by Pseudotsuga menziesii at the expense of luxury consumption by Pinus ponderosa. Graphical analysis suggested that better growth of Pseudotosuga menziesii in mixture with EMF added was related to improved P nitrogen. Both N and P nutrition of Pinus ponderosa was better in mixture with two than no EMF species added; there was no clear nutrient effect with four EMF species added. Results indicate that EMF can reduce competition between plant species and perhaps increase overall community P uptake. However, patterns were specific to both EMF and tree species and were quite different in unpasteurized soils. Hence generalizations about the effects of EMF on plant-plant interactions must be made cautiously.

Abstract
Recent studies of health effects from chronic exposure to noise in the workplace have not consistently addressed nonoccupational variables. A cross-sectional study was conducted with 197 randomly selected male hourly workers from a noisy plant (greater than or equal to 89 dBA) in Pittsburgh to fully assess noise exposure and hearing loss, incorporating information on duration of exposure, noise level, occupational and medical histories, audiometric evaluation, and external noise sources. Population audiometric profiles are characteristic of noise-induced hearing loss; mean hearing thresholds for press room men were significantly higher at 2, 3, and 6 kHz (p less than or equal to .05). Only 40% of the men consistently wore hearing protection. Recent use of ototoxic drugs, noisy hobbies/second jobs, military service, family history of hearing loss, and ear-related problems were not found to have a significant effect on hearing levels at high frequencies, suggesting that observed hearing losses were of an occupational origin.

Abstract
Myklebust's Pupil Rating Scale (PRS) was administered to the first (n = 92) and second (n = 130) grades of a middle class suburban elementary school to ascertain its effectiveness for predicting reading and arithmetic difficulties. The results of this investigation were compared with those obtained in a large pilot study (n = 98) with a similar second grade population from another school district. After obtaining overall correlations between the PRS and achievement and examining those PRS scores Myklebust found indicative of academic difficulty, it was concluded that the predictive efficiency of the PRS at these grade levels must remain suspect until sufficient countervailing evidence supporting its predictive utility is presented.

Abstract
Clinical and morphologic features of seven T-cell lymphomas of the large cell type are described. The tumors were grouped into those with irregular (3 cases) and those with round and regular nuclei (4 cases). In both groups, variation in cell size, numerous histiocytes and vessels, and many mitoses were distinguishing features. In only 1 case in the round and regular nucleus group was there relatively little variation in cell size and a paucity of histiocytes. Abundant polyribosomes, long strands of rough endoplasmic reticulum, and lysosomal granules were prominent electron microscopic features in both groups of tumors. The clinical presentations and courses varied considerably, especially in patients with tumors of the round nucleus type. One patient presented initially with chronic lymphocytic leukemia, 1 with Lennert's lymphoma, another with bone marrow infiltration, and a fourth with subcutaneous tumors. Two patients with the round nucleus type are still alive one and a half and two years after the original diagnosis. Two patients died two years after the onset of symptoms. Each of the 3 patients with tumors of the irregular nucleus type had a rapid clinical course and died within ten months.

Abstract
A modified downward extension of Birch and Belmont's auditory-visual integration test was correlated with the Metropolitan Readiness Test for 82 middle class kindergarten children. From this same sample the test performances of an equal numer (n = 11) of impulsive females, impulsive males, reflective females, and reflective males were compared with use of a 2 X 2 analysis of variance. An analysis of convariance was employed to further examine test performance. Metropolitan scores were equated for Verbal IQ; for auditory-visual integration, test response time and Verbal IQ were individually held constant. Auditory-visual integration variance accounted for 29% of Metropolitan variance. Reflectives performed significantly better than impulsives on the auditory-visual integration test with or without response time or WPPSI Verbal IQ held constant; they performed significantly better than impulsives on the Metropolitan, but this did not maintain when scores were equated for WPPSI Verbal IQ.
