- Abstract
Reducing the gap between research and practice is gaining much needed attention. Schools of public health can play a role by ensuring that students are taught the necessary knowledge and skills to translate research into practice and to effectively disseminate research and other public health information. Competency-based education is one mechanism by which this can occur. In this article, we introduce a set of competencies specific to translation and dissemination. We describe the process used to develop the set as well as the ways in which we have begun to use these competencies for curriculum review and development. In this way, other schools and training programs in public health can begin to design curricula that will prepare their students to reduce the gap between research and practice. Graduate students will thus be effectively prepared to respond to the changing demands of the field of public health. [ABSTRACT FROM AUTHOR]

- Abstract
There has been tremendous growth in the cellular telephone industry in recent years. The present study was undertaken in order to better understand the pattern of usage among one of the most important target markets for cell phone products-young adults attending college. Data were collected from a total of 383 cell phone consumers residing in four states in different geographic regions of the United States. Respondents ranged in age from 18-57 with a median age of 23 years. Data analyses revealed several interesting and potentially important patterns of usage. Among these were the findings that the majority of those surveyed indicated that they use their cell phones for the purpose of social stimulation, to remain continually available, for domestic reasons, to leave themselves memos and reminders, for time-keeping, for emergency purposes, and to use the phone's phonebook function. It was also found that the cell phone market among the target population is relatively mature in that the vast majority of the sample (90.5%) indicated that they have owned a cell phone for more than one year. The maturity of the market, however, was found to vary as a function of geographic region. This particular finding has implications for regional cell phone marketing strategies. A number of other differences of potential importance for market segmentation and target marketing purposes also emerged and are discussed in detail. [ABSTRACT FROM AUTHOR]

- Abstract
A regional research effort in the Northeast section of the United States (NE-172) has been carried out in 5-year cycles over the last 15 years to study nutritional problems of the older adult. Many aspects of dietary methodology, biochemical parameters (including biomarkers), and nutrition education strategies have been examined. Integration of these research techniques in studies across the region has been the focus of several recent collaborative projects. Ongoing efforts continue to be applied to areas of study specific to the needs of an expanding population base of elders in America. [ABSTRACT FROM AUTHOR]

Charge neutralization of rubidium cluster ions (Rb N + ) by Rb atomic vapor is reported. The cluster ions are generated by a liquid metal ion source (LMIS). The ions and the neutrals are detected directly without any photoionization step. The extent of dissociative neutralization is negligible. This results in intense, mass-selected neutral cluster beams. The charge exchange cross sections for Rb 2 + and Rb 3 + with Rb, are 9.3× 10 −15 and 3.1 × 10 −15 cm 2 respectively.

This study tested the accuracy of a quantitative food frequency questionnaire (FFQ) designed to assess the amount of calcium consumed daily and to useas an educational tool in diet counseling and for prescribing calcium supplementation. The subjects were 26 perimenopausal women, aged 48 to 56 years, who were participants in a longitudinal osteoporosis study. Diets of the subjects were studied during the winter andsummer of one year. Subjects filled out a food frequency questionnaire and the next week completed 4-day food intake records according to instructions from the researchers. The mean daily intake of calcium estimated from the food frequency questionnaire was 928 mg inthe winter and 912 mg 6 months later. Ranges in the winter were 227 to 2,243 mg calcium and in the summer 198 to 3,063 mg calcium. The 53-item FFQ included descriptions of portion sizes and a calcium index for each item and had options for two frequency periods. The calcium level estimated from the questionnaire correlated (r=.73 in winter and r= .84 in summer) with the estimated amount from 4-day records. A seasonal difference was not found.

- Abstract
Background: The symbiosis between the Hawaiian bobtail squid Euprymna scolopes and bacterium Vibrio fischeri serves as a model for investigating the molecular mechanisms that promote the initial formation of animal-bacterial symbioses. Research with this system frequently depends on freshly hatched E. scolopes, but the husbandry factors that promote hatchling production in a mariculture facility remain underreported. Here we report on the reproductive performance of E. scolopes in response to decreased mating frequency., Results: One animal cohort was maintained in a mariculture facility for 107 days, with females assigned to either a control group (mating once every 14 days) or an experimental group (mating once every 21 days). No differences between the groups were observed in survival, the number of egg clutches laid, or hatchling counts. Each group featured multiple females that were hyper-reproductive, i.e., they generated more than 8 egg clutches while in captivity. Examination of the distributions for daily hatchling counts of individual egg clutches revealed significant variation in the hatching patterns among clutches that was independent of mating frequency. Finally, an assessment of hatchling production showed that 93.5% of total hatchlings produced by the cohort were derived from egg clutches laid within the first 70 days., Conclusions: These results suggest a lower mating frequency does not impede hatchling production. Furthermore, the variation in hatchling production among egg clutches provides new insight into the reproductive performance of E. scolopes as a lab animal for microbiology research., (© 2023.

- Abstract
Most animals establish long-term symbiotic associations with bacteria that are critical for normal host physiology. The symbiosis that forms between the Hawaiian squid Euprymna scolopes and the bioluminescent bacterium Vibrio fischeri serves as an important model system for investigating the molecular mechanisms that promote animal-bacterial symbioses. E. scolopes hatch from their eggs uncolonized, which has led to the development of squid-colonization assays that are based on introducing culture-grown V. fischeri cells to freshly hatched juvenile squid. Recent studies have revealed that strains often exhibit large differences in how they establish symbiosis. Therefore, we sought to develop a simplified and reproducible protocol that permits researchers to determine appropriate inoculum levels and provides a platform to standardize the assay across different laboratories. In our protocol, we adapt a method commonly used for evaluating the infectivity of pathogens to quantify the symbiotic capacity of V. fischeri strains. The resulting metric, the symbiotic dose-50 (SD50), estimates the inoculum level that is necessary for a specific V. fischeri strain to establish a light-emitting symbiosis. Relative to other protocols, our method requires 2-5-fold fewer animals. Furthermore, the power analysis presented here suggests that the protocol can detect up to a 3-fold change in the SD50 between different strains., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Donnelly et al.

- Abstract
AbstractThe scarcity of asexual reproduction in vertebrates alludes to an inherent cost. Several groups of asexual vertebrates exhibit lower endurance capacity (a trait predominantly sourced by mitochondrial respiration) compared with congeneric sexual species. Here we measure endurance capacity in five species of Aspidoscelis lizards and examine mitochondrial respiration between sexual and asexual species using mitochondrial respirometry. Our results show reduced endurance capacity, reduced mitochondrial respiration, and reduced phenotypic variability in asexual species compared with parental sexual species, along with a positive relationship between endurance capacity and mitochondrial respiration. Results of lower endurance capacity and lower mitochondrial respiration in asexual Aspidoscelis are consistent with hypotheses involving mitonuclear incompatibility.

- Abstract
Managed environmental flows are one mechanism by which managers may restore carbon dynamics, diversity and ecological function of rivers affected by anthropogenic activities. Empirical studies that quantify such interactions in detail are few, so we measured the amounts of dissolved organic carbon, nutrients, algae and invertebrates in the main river channel following a managed environmental flow that inundated an adjacent floodplain forest. Dissolved organic carbon (DOC), seston carbon, total nitrogen (TN), and chlorophyll-a (chl-a) concentrations were greatly increased downstream. The net yield of DOC, seston carbon, TN and chl-a from the floodplain peaked at approximately 100, 50, 5 and 0.1 t d
-1 , respectively during the major flow event. Total phosphorus mobilisation peaked at approximately 0.4 t d-1 . Stable isotope analysis showed that allochthonously-derived carbon was rapidly incorporated into biofilm and grazing macroinvertebrates, persisting in riverine food webs for up to four months following the flood. During a subsequent smaller flow event, the floodplain either generated no further carbon or nutrients, or was a sink for carbon and nutrients. Our results provide empirical support for the River Wave Concept and show that allowing floodplain water to return to the river downstream of forests is important for maintaining ecological function within the river channel., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier B.V.

- Abstract
Despite being the most numerous penguin species in South America, exposure of the Magellanic Penguin ( Spheniscus magellanicus ) to pathogens has not yet been thoroughly assessed. We collected serum from 1,058 Magellanic Penguins at 10 breeding colonies along the entire latitudinal range of this species in Argentina. The work spanned 10 breeding seasons over 15 yr (1994-2008). Sera were tested for antibodies to select infectious agents. Antibodies reacting against 16 pathogens were detected (seroprevalence): Aspergillus sp. (15.1%), Chlamydia psittaci (6.5%), Salmonella Pullorum (3.1%), Salmonella Typhimurium (81.3%), Aviadenovirus sp. (18.1%) , Duck atadenovirus A (23.6%), Anatid herpesvirus 1 (0.7%), Avian orthoreovirus (3.3%), Avian coronavirus M41 (43.5%), Avian coronavirus C46 (59.8%), Avian coronavirus A99 (37.4%), Avian coronavirus JMK (40.2%), Tremovirus A (0.3%), Avian avulavirus 1 (44.0%), Avian avulavirus 2 (43.8%), and Avian avulavirus 3 (46.6%). No antibodies were detected against nine infectious agents: Gallid alphaherpesvirus 1 , Gallid alphaherpesvirus 2 , Infectious bursal disease virus , Avastrovirus 2 , West Nile virus , Eastern equine encephalitis virus , Venezuelan equine encephalitis virus , Western equine encephalitis virus , and Influenza A virus . While restricted by limitations inherent to serological methods, our results provide baseline knowledge for a key species in the South Atlantic Ocean. This information is valuable for adaptive conservation management in a time of increasing environmental stressors affecting the Patagonian Sea, one of the world's richest pelagic seabird communities.

- Abstract
Background: The Personal Genome Project Canada is a comprehensive public data resource that integrates whole genome sequencing data and health information. We describe genomic variation identified in the initial recruitment cohort of 56 volunteers., Methods: Volunteers were screened for eligibility and provided informed consent for open data sharing. Using blood DNA, we performed whole genome sequencing and identified all possible classes of DNA variants. A genetic counsellor explained the implication of the results to each participant., Results: Whole genome sequencing of the first 56 participants identified 207 662 805 sequence variants and 27 494 copy number variations. We analyzed a prioritized disease-associated data set ( n = 1606 variants) according to standardized guidelines, and interpreted 19 variants in 14 participants (25%) as having obvious health implications. Six of these variants (e.g., in BRCA1 or mosaic loss of an X chromosome) were pathogenic or likely pathogenic. Seven were risk factors for cancer, cardiovascular or neurobehavioural conditions. Four other variants - associated with cancer, cardiac or neurodegenerative phenotypes - remained of uncertain significance because of discrepancies among databases. We also identified a large structural chromosome aberration and a likely pathogenic mitochondrial variant. There were 172 recessive disease alleles (e.g., 5 individuals carried mutations for cystic fibrosis). Pharmacogenomics analyses revealed another 3.9 potentially relevant genotypes per individual., Interpretation: Our analyses identified a spectrum of genetic variants with potential health impact in 25% of participants. When also considering recessive alleles and variants with potential pharmacologic relevance, all 56 participants had medically relevant findings. Although access is mostly limited to research, whole genome sequencing can provide specific and novel information with the potential of major impact for health care., Competing Interests: Competing interests: Stephen Scherer serves on the Scientific Advisory Committees of Population Bio and Deep Genomics.

- Abstract
Posttraumatic stress disorder (PTSD) is a symptom cluster of intrusion, avoidance, negative alteration in cognition, and alteration in arousal and reactivity following trauma. PTSD occurs frequently after a physical trauma such as a severe hand injury. It is often not recognized and consequently untreated. Previous research has shown that 10%-40% of civilian trauma survivors experience PTSD in the first 12 months after injury. There is great urgency to identify patients in the early stage of recovery from trauma, as PTSD becomes more difficult to treat in its chronic form. Mangling hand injuries are particularly disabling because they are an integral part of our social body image. We wanted to investigate the degree of PTSD screening and the follow-up-referral procedures in all mangled hand cases at the hand clinic of a large Northwestern Trauma Center. A retrospective medical record review was conducted from January to December 2012 using an existing PTSD screen with data from the electronic medical records. We found that 40% of the patients with mangled hand injury were classified as "at risk" according to our PTSD screening but only 22% of those cases were referred to rehabilitation psychiatry for further evaluation and treatment. The low rate of referral for PTSD after mangled hand injury was alarming. On the basis of this, we instituted a new screening protocol for all patients with mangled hand injury using the 4-item Primary Care-PTSD screening tool and provided an informational brochure on PTSD. The investigation led to a positive change in the practice environment and workflow of the clinic. We have not conducted any follow-up study as yet, but our goal is to screen all patients with mangled hand injury and refer all patients for psychiatric therapy who have positively answered 3 of the 4 screening questions.

- Abstract
Objectives: We investigate intracemetery biological variation at the Fort Ancient SunWatch village (800-500 BP.) to test the hypothesis that the SunWatch population consisted of spatially structured biologically differentiated kin groups consisting of distinct local Late Woodland and non-local Mississippian biological populations., Material and Methods: The SunWatch sample contains 166 individuals: 63 adults and 103 subadults. We analyze intracemetery biological variation using two feature sets: the buccolingual diameters of the polar teeth in the permanent (n = 37) and deciduous (n = 26) dentitions. We apply matrix correlation models to biodistance and grave distance matrices in both data sets, evaluate burial outliers and individuals exhibiting a rare dental feature with interindividual biological distances, and evaluate potential cultural subgroups with Mahalanobis' distance., Results: Matrix correlation analyses for both feature sets as well as interindividual and subgroup distances indicate the SunWatch village cemetery was kin structured, contained a single primary biological population, and also contained a small number of non-local individuals most of whom were from closely related populations. We thus reject the hypothesis that the SunWatch population consisted of biologically distinct Late Woodland and Mississippian biological populations., Discussion: Although SunWatch village exhibited cultural attributes characteristic of both local Late Woodland and non-local Mississippian groups, biologically the village was composed of one primary population. The lack of evidence for marked biological differentiation in the SunWatch village area at about 800-500 BP. suggests diffusion and acculturation may account for Mississippian cultural characteristics in southwestern Ohio Fort Ancient villages. If gene flow or migrations from biologically distinct Mississippian populations into southwestern Ohio occurred, either or both likely occurred well before 800 BP. This would have allowed the process of admixture time to produce a relatively homogeneous, nondifferentiated population. The latter alternative is consistent with the appearance in southwestern Ohio of non-local individuals at one site linked to surrounding Mississippian regions at about 950 BP.

Objective: This study sought to characterize sleep patterns and sleep problems in a large sample of women across all months of pregnancy., Methods: A total of 2427 women completed an Internet-based survey that included the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale, vitality scale of the Short Form 36 Health Survey (SF-36), Insomnia Severity Index (ISI), Berlin questionnaire, International Restless Legs Syndrome (IRLS) question set, and a short version of the Pregnancy Symptoms Inventory (PSI)., Results: Across all months of pregnancy, women experienced poor sleep quality (76%), insufficient nighttime sleep (38%), and significant daytime sleepiness (49%). All women reported frequent nighttime awakenings (100%), and most women took daytime naps (78%). Symptoms of insomnia (57%), sleep-disordered breathing (19%), and restless legs syndrome (24%) were commonly endorsed, with no difference across the month of pregnancy for insomnia, sleep-disorder breathing, daytime sleepiness, or fatigue. In addition, high rates of pregnancy-related symptoms were found to disturb sleep, especially frequent urination (83%) and difficulty finding a comfortable sleep position (79%)., Conclusions: Women experience significant sleep disruption, inadequate sleep, and high rates of symptoms of sleep disorder throughout pregnancy. These results suggest that all women should be screened and treated for sleep disturbances throughout pregnancy, especially given the impact of inadequate sleep and sleep disorders on fetal, pregnancy, and postpartum outcomes., (Copyright © 2014 Elsevier B.V.

- Abstract
This study examines a perennial problem in anthropology, changes in postmarital residence patterning. Cross-cultural patterns related to shifts from patrilocal to matrilocal patterns have been attributed to changes in subsistence and/or the result of migrants entering a populated region. Shifts from matrilocal to multilocal patterns have been found to be related to depopulation. This study examines these possibilities in an archeological context through morphometric analyses of human dentition. Comparisons in variability among males and females are made at four Fort Ancient sites in the Middle Ohio Valley that date to sequential time periods between circa A.D. 1000 and 1650. Results show that the earliest site (Turpin) that was occupied during the transition to maize agriculture was patrilocal, whereas two subsequent sites (Anderson and SunWatch) that were occupied after the transition to a maize-focused diet reflect a matrilocal pattern. The most recently occupied site (Madisonville), occupied during a time of depopulation of the region after a decline in levels of maize consumption and a marked population shuffling contains a multilocal pattern. These results fit well with the various cross-cultural findings regarding shifts in postmarital residence patterns.

- Abstract
This report describes the use of a single shot, through the needle caudal approach to epidural blood patch (EBP) in a patient with persistent leakage of cerebrospinal fluid following lumbosacral laminectomy. A previous report of caudal EBP in an adult patient with an epidural catheter suggested that the success of the procedure could be comparable without the use of a catheter. This case report documents the success of through the needle caudal EBP in an adult patient.

- Abstract
Mosquito species abundance and composition estimates provided by trapping devices are commonly used to guide control efforts, but knowledge of trap biases is necessary for accurately interpreting results. We tested the hypothesis that commercially available traps (Mosquito Magnet-Pro, the Mosquito Magnet-X) would be significant improvements over the CDC Miniature Light Trap with respect to abundance, species diversity, and measures of recruitment in a wooded area of the Bronx Zoo in New York City, NY. The Mosquito Magnet-Pro collected significantly more mosquitoes (n = 1,117; mean per night, 124 +/- 28.3) than the CDC Miniature Light Trap (n = 167; mean per night, 19 +/- 5.5). The Simpson's diversity index was greatest for the Mosquito Magnet-Pro. A CDC light trap from a simultaneous surveillance project was located 15 m away and used as a control trap to test for significant differences in mosquito counts on nights with or without the experimental traps. There were no significant differences between nights, indicating the test traps did not recruit beyond 15 m. The traps differed significantly in abundance, but they had similarly limited sampling areas. Measured differences in abundance were independent of differences in diversity. This study highlights how differences between traps might affect species abundance and composition estimates.

- Abstract
As part of ongoing ecological studies of Humboldt penguins (Spheniscus humboldti) at Punta San Juan, Ica Department, Peru, health surveys were conducted in November 1992, 1993, and 1994. In the three surveys, 98 birds in total were handled for examination, and blood was collected for laboratory analysis from 90 of these birds. All birds seemed to be in good condition. Body weights of females were significantly lower in 1994 than in the other years. Fleas (Parapsyllus humboldti) and ticks (Ornithodoros amblus) were found on the penguins and in their nests. Females had significantly higher plasma calcium and phosphorus levels, and they had lower weights than males. No other differences were found between the sexes. Hematology, plasma chemistries, and plasma mineral levels varied between years. Positive antibody titers for Chlamydophila psittaci (62%), avian adenovirus (7%; 1994 only), paramyxovirus-2 (7%; 1993 only), and Salmonella Pullorum (7%) were found. Plasma chemistry and mineral levels differed between individuals testing positive vs. negative on serologic tests for avian adenovirus and Salmonella Pullorum. Serologic tests for antibodies to avian influenza A virus, avian encephalomyelitis virus, infectious bronchitis virus, avian reovirus, duck viral enteritis virus, equine encephalitis (eastern, western, and Venezuelan) viruses, infectious bursal disease virus, infectious laryngotracheitis virus, Aspergillus sp., and paramyxovirus-1 and -3 were negative. All chlorinated pesticide and polychlorinated biphenyl analyses were below detectable limits.

- Abstract
Unlabelled: Heart disease is a leading cause of death in North America. With the increased availability of PET/CT scanners, CT is now commonly used as a transmission source for attenuation correction. Because of the differences in scan duration between PET and CT, respiration-induced motion can create inconsistencies between the PET and CT data and lead to incorrect attenuation correction and, thus, artifacts in the final reconstructed PET images. This study compared respiration-averaged CT and 4-dimensional (4D) CT for attenuation correction of cardiac PET in an in vivo canine model as a means of removing these inconsistencies., Methods: Five dogs underwent respiration-gated cardiac (18)F-FDG PET and 4D CT. The PET data were reconstructed with 3 methods of attenuation correction that differed only in the CT data used: The first method was single-phase CT at either end-expiration, end-inspiration, or the middle of a breathing cycle; the second was respiration-averaged CT, which is CT temporally averaged over the entire respiratory cycle; and the third was phase-matched CT, in which each PET phase is corrected with the matched phase from 4D CT. After reconstruction, the gated PET images were summed to produce an ungated image. Polar plots of the PET heart images were generated, and percentage differences were calculated with respect to the phase-matched correction for each dog. The difference maps were then averaged over the 5 dogs., Results: For single-phase CT correction at end-expiration, end-inspiration, and mid cycle, the maximum percentage differences were 11% +/- 4%, 7% +/- 3%, and 5% +/- 2%, respectively. Conversely, the maximum difference for attenuation correction with respiration-averaged CT data was only 1.6% +/- 0.7%., Conclusion: Respiration-averaged CT correction produced a maximum percentage difference 7 times smaller than that obtained with end-expiration single-phase correction. This finding indicates that using respiration-averaged CT may accurately correct for attenuation on respiration-ungated cardiac PET.

- Abstract
Objective: Determine 1) if consumption of a meal of different fruits or berries increases plasma hydrophilic (H-) or lipophilic (L-) antioxidant capacity (AOC) measured as Oxygen Radical Absorbance Capacity (ORAC(FL)); 2) if including macronutrients in the meal alters postprandial changes in AOC; and 3) if preliminary recommendations can be developed for antioxidant intake., Methods: Changes in plasma AOC following consumption of a single meal of berries/fruits (blueberry, dried plum, dried plum juice, grape, cherry, kiwifruit and strawberry) were studied in 5 clinical trials with 6-10 subjects per experiment. In two studies with blueberry or grape, additional macronutrients (carbohydrate, fat, protein) were included in the control and treatment meals. Blood samples collected before and after the meal were analyzed for AOC., Results: Consumption of dried plums or dried plum juice did not alter either the H- or L-AOC area under the curve (AUC). Consumption of blueberry in 2 studies and of mixed grape powder [12.5 (Study #1), 39.9 (Study #4) and 8.6 (Study #5) mmole Trolox Equivalents (TE) AOC, respectively] increased hydrophilic AOC AUC. L-AOC increased following a meal of blueberry containing 12.5 mmole TE AOC (Study #1). Consumption of 280 g of cherries (4.5 mmol TE AOC) increased plasma L-AOC but not H-AOC. The AOC in the control groups in which additional macronutrients (Studies #4 and #5) were added decreased from the postprandial baseline AOC measurement., Conclusion: We have demonstrated that consumption of certain berries and fruits such as blueberries, mixed grape and kiwifruit, was associated with increased plasma AOC in the postprandial state and consumption of an energy source of macronutrients containing no antioxidants was associated with a decline in plasma AOC. However, without further long term clinical studies, one cannot necessarily translate increased plasma AOC into a potential decreased risk of chronic degenerative disease. Preliminary estimates of antioxidant needs based upon energy intake were developed. Consumption of high antioxidant foods with each meal is recommended in order to prevent periods of postprandial oxidative stress.

- Abstract
Published serum cholesterol values in captive western lowland gorillas (Gorilla gorilla gorilla) are much higher than human ranges, with a national mean of 7.36 mmol/L (284 mg/dl, n = 863). Complete blood lipid profiles were examined in 15 captive gorillas. High-density lipoprotein (HDL) was found to decrease more rapidly with age than total cholesterol, resulting in an increasing ratio of cholesterol HDL with age. The ratio of apolipoprotein B to apolipoprotein Al also increased with age. Establishment of a database of blood lipid values for captive gorillas with correlative analysis of animals with known atherosclerosis status may help to identify sensitive predictors of coronary heart disease risk.

- Abstract
The global trade in wildlife provides disease transmission mechanisms that not only cause human disease outbreaks but also threaten livestock, international trade, rural livelihoods, native wildlife populations, and the health of ecosystems. Outbreaks resulting from wildlife trade have caused hundreds of billions of dollars of economic damage globally. Rather than attempting to eradicate pathogens or the wild species that may harbor them, a practical approach would include decreasing the contact rate among species, including humans, at the interface created by the wildlife trade. Since wildlife marketing functions as a system of scale-free networks with major hubs, these points provide control opportunities to maximize the effects of regulatory efforts.

- Abstract
Baseline data on health of free-ranging wildlife is essential to evaluate impacts of habitat transformation and wildlife translocation, rehabilitation, and reintroduction programs. Health information on many species, especially great apes, is extremely limited. Between 1996 and 1998, 84 free-ranging orangutans captured for translocation, underwent a complete health evaluation. Analogous data were gathered from 60 semi-captive orangutans in Malaysia. Baseline hematology and serology; vitamin, mineral and pesticide levels; and results of health evaluations, including physical examination, provide a baseline for future monitoring. Free-ranging and semi-captive orangutans shared exposure to 11 of 47 viruses. The semi-captive orangutans had significantly higher prevalence of antibodies to adenovirus (P < 0.0005) and rota (SA 11) virus (P < 0.008). More free-ranging than semi-captive animals had antibodies to Japanese encephalitis virus (P < 0.08) and foamy virus (P = 0.05). Exposure to parainfluenza and langat viruses was detected exclusively in semi-captive animals and exposure to sinbis virus was only found in free-ranging orangutans. There was evidence of exposure to respiratory syncytial virus, coxsackie virus, dengue virus, and zika virus in both groups. Ebstein-Barr virus was ubiquitous in both groups. Prevalence of antibodies against mumps virus changed from 0% in 1996 to 45% in 1998. No antibodies were detected to many important zoonotic viral pathogens, including herpesvirus and hepatitis virus. Prevalence of Balantidium coli and Plasmodium pitheci infections and exposure to mycobacterium was higher in the semi-captive animals. Differences in exposure to pathogens between the groups may be due to environmental factors including differences in exposures to other species, habitat quality, nutritional status, and other potential stressors. Differences in health parameters between captive and free-ranging orangutans need to be considered when planning conservation areas, translocation procedures, and rehabilitation protocols. Because survival of the orangutan is linked to animal and ecosystem health, results of this study will assist wildlife conservation programs by providing baseline health information.

- Author

Mehnert CP, Cook RA, Dispenziere NC, and Afeworki M
- Abstract
The new concept of supported ionic liquid catalysis involves the surface of a support material that is modified with a monolayer of covalently attached ionic liquid fragments. Treatment of this surface with additional ionic liquid results in the formation of a multiple layer of free ionic liquid on the support. These layers serve as the reaction phase in which a homogeneous hydroformylation catalyst was dissolved. Supported ionic liquid catalysis combines the advantages of ionic liquid media with solid support materials which enables the application of fixed-bed technology and the usage of significantly reduced amounts of the ionic liquid. The concept of supported ionic liquid catalysis has successfully been used for hydroformylation reactions and can be further expanded into other areas of catalysis.

- Abstract
An outbreak of West Nile virus (WNV) in and around New York City during the late summer of 1999 was the cause of extensive mortality among free-ranging birds. Within the Bronx Zoo/Wildlife Conservation Park, viral activity was also observed and produced some morbidity and mortality among specimens in the zoo's bird collection and probably caused morbidity in at least one specimen from the zoo's mammal collection. To determine the extent of the outbreak and attempt to ascertain the temporal appearance of virus within the park, a serologic survey of birds and mammals was performed. The survey showed that 34% of tested birds (125 of 368; 124 species) were positive for antibody to WNV. The virus caused a disease to infection ratio of 22% (27 of 125) among birds with a 70% (19 of 27) case fatality rate. In contrast, only 8% of the mammals (9 of 117; 35 species) possessed antibody to WNV and there was no virus-associated mortality. Testing of banked and fresh sera obtained from both birds and mammals revealed that there was no evidence of WNV circulation before the 1999 outbreak and that birds introduced into the park were not the source of the New York outbreak. West Nile virus RNA was detected in tissues from one bird that died in February 2000, long after the end of the mosquito transmission season. The potential importance of zoologic parks as possible sentinels for emerging diseases is discussed.

- Abstract
Ankle arthritis has traditionally been treated surgically with arthrodesis (fusion) after conservative measures have been exhausted. The success of joint arthroplasty in the knee, hip, and shoulder inspired many attempts over the past 30 years to construct a workable ankle prosthesis. The failures of first generation prostheses caused skepticism regarding the feasibility of total ankle arthroplasty (TAR), but the mistakes of the past have been transformed into improvements and modifications. Today's second generation total ankle designs show promise, and outcomes are encouraging. The Agility Ankle (DePuy, Warsaw, IN) designed by Dr. Frank Alvine is featured in this article. The method of implant and postoperative management are reviewed.

- Abstract
Diagnosis of active mycobacterial disease in orangutans (Pongo pygmaeus) has been impeded by high levels of non-specific intradermal skin test reactivity to mycobacterial antigens. This may be due in part to cross reactivity between antigens, tuberculin concentrations used or other species-specific factors. Antigen 85 (Ag85) complex proteins are major secretory products of actively growing mycobacteria, and measurement of serum Ag85 could provide a method for determining active mycobacterial infections that was not dependent on host immunity. Serum Ag85 was measured by dot-immunobinding assay using monoclonal anti-Ag85, purified Ag85 standard and enhanced chemiluminescence technology in coded serum samples from 14 captive orangutans from a zoo in Colorado, 15 semi-captive orangutans in Malaysia, and 19 free-ranging wild orangutans in Malaysia. Orangutans from Colorado (USA) were culture negative for Mycobacterium tuberculosis and M. avium, although all had laboratory suspicion or evidence of mycobacterial infection; median serum Ag85 was 10 microU/ml (range, <0.25-630 microU/ml). Of the semi-captive orangutans, six were skin test reactive and two were culture positive for M. avium on necropsy. Median serum Ag85 for this group was 1,880 microU/ml (0.75-7,000 microU/ml), significantly higher than that of Colorado zoo or free-ranging Malaysian orangutans. Median serum Ag85 in the latter group was 125 microU/ml (range, 0.75-2,500 microU/ml). These data suggest that suggest that additional studies using more specific reagents and more samples from animals of known status are appropriate.

- Abstract
The Field Veterinary Program (FVP) of the Wildlife Conservation Society (WCS) was created in 1989 to combat the wildlife disease and health problems that increasingly complicate the process of wildlife conservation. The FVP provides veterinary services for the more than 300 WCS conservation projects located in more than 50 countries around the world. Most of these projects are in tropical regions and many have a wildlife/domestic livestock component. Wildlife health care provided by the FVP staff includes (1) identifying critical health factors; (2) monitoring health status; (3) crisis intervention; (4) developing and applying new technologies; (5) animal handling and welfare concerns; and (6) training. Additionally, the staff of the FVP give expert advice to many governmental and non-governmental agencies that are involved in setting policies directly related to wildlife health and conservation issues. In this paper, two FVP projects are presented as examples of studies that have increased our understanding of the role wildlife diseases may play in the health of livestock and human populations, as well as the role humans and livestock may play in the health of wildlife populations. Examples of the collaborative work between the FVP staff and scientists from many disciplines (e.g., acarologists, mycobacterium experts, ecologists, and biologists) are also presented.

- Abstract
Twelve babirusa (Babyrousa babyrussa) (four females/eight males) were immobilized 30 times during a 4-yr interval. Significantly higher premedication and immobilizing doses were needed for females than for males (P < 0.05). An i.m. preanesthetic xylazine dose of 1.88 +/- 0.37 mg/kg (range = 1.20-2.12 mg/kg) was used for females and 1.22 +/- 0.16 mg/kg (range = 0.82-1.43 mg/kg) for males. After xylazine, the animals were induced with i.m. tiletamine/zolazepam; females received 2.20 +/- 0.47 mg/kg (range = 1.78-3.33 mg/kg) and males received 1.71 +/- 0.34 mg/kg (range = 1.08-2.05 mg/kg). Anesthesia was reversed with yohimbine (0.14 +/- 0.03 mg/kg; range = 0.07-0.20 mg/kg) and flumazenil (1 mg flumazenil/20 mg zolazepam) either i.m. or i.v. This anesthetic combination produced smooth induction, good relaxation, and sufficient immobilization to perform routine diagnostic and therapeutic procedures (venipuncture, hoof and tusk trims, transportation, radiographs, ultrasound examination, weight determinations, and skin biopsies). Supplemental ketamine HCl or isoflurane was administered to two animals to effectively deepen or prolong the anesthetic plane, with no resultant adverse effects.

- Abstract
Antemortem diagnosis of tuberculosis in captive wild animals is often difficult. In addition to the variability of host cellular immune response, which does not always indicate current active infection, reactivity to saprophytic or other mycobacteria is common and may interfere with the interpretation of the intradermal tuberculin skin test. Furthermore, the immobilization required for administering the test and evaluating skin reactions in these animals may result in unacceptable levels of morbidity and mortality, of particular concern in individuals of rare or endangered species. Proteins of the antigen 85 (Ag85) complex are major secretory products of actively metabolizing mycobacteria in vitro. Production of these proteins by mycobacteria during growth in vivo could result in increases in circulating levels of Ag85 in hosts with active tuberculosis. A dot blot immunoassay has been used to detect and quantify circulating Ag85 in captive wild animals with tuberculosis. Elevated levels of Ag85 were observed in animals with active tuberculosis as compared with uninfected animals. Study populations included a herd of nyala (Tragelaphus angasi) (n = 9) with no history of exposure to Mycobacterium bovis. Serum Ag85 levels ranged from <5 to 15 microU/ ml (median, 5 microU/ml). The other group included 11 animals from a mixed collection with a documented history of an M. bovis outbreak. Animals with pulmonary granulomatous lesions (n = 3) had serum Ag85 levels ranging from 320 to 1,280 microU/ml (median, 320 microU/ml). Animals with only chronic mediastinal or mesenteric lymphadenitis (n = 4) had serum Ag85 levels ranging from <5 to 320 microU/ml (median, 52.5 microU/ml). Animals with no lesions present on necropsy (n = 4) had serum Ag85 levels ranging from <5 to 80 microU/ml (median, <5 microU/ml). This assay could provide an important adjunct to intradermal skin testing for antemortem diagnosis of tuberculosis in nondomestic species.

- Abstract
As part of annual colony counts in Santa Cruz Province, Argentina, a health survey of rockhopper penguins (Eudyptes chrysocomes) was conducted in 1994. Forty-five birds were examined during handling procedures, and blood and fecal samples were collected for laboratory analysis. All birds appeared to be in good condition. No ecto- or endoparasites were found. Hematology, plasma chemistry, and plasma mineral levels were measured and correlated with the results of bacterial and viral serology. Antibodies against Chlamydia sp., avian adenovirus, avian encephalomyelitis virus, infectious bronchitis virus, avian reovirus, and paramyxovirus-1, -2, and -3 were found. Mean plasma chemistry and mineral values differed between individuals testing positive and negative on serologic tests. There was no serologic evidence of exposure to avian influenza virus, duck viral enteritis, infectious bursal disease, infectious laryngotracheitis, Aspergillus sp., or Salmonella pullorum. Trace amounts of endrin were found in the plasma of one bird, but all other chlorinated pesticide and polychlorinated biphenyl levels were below detectable limits.

- Abstract
Twenty free-ranging guanaco (Lama guanicoe) in Chubut Province, Argentina, were immobilized for health evaluations. All but two animals appeared to be in good condition. Hematology, serum chemistry, and vitamin and mineral levels were measured, and feces were evaluated for parasites. Serology tests included bluetongue, brucellosis, bovine respiratory syncitial virus, bovine viral diarrhea/mucosal disease, equine herpesvirus 1, infectious bovine rhinotracheitis, Johne's disease (Mycobacterium paratuberculosis), foot and mouth disease, leptospirosis (17 serovars), parainfluenza-3, and vesicular stomatitis. Blood samples from 20 domestic sheep (Ovis aries) maintained in the same reserve with the guanaco were also collected at the same time for serology tests. No guanaco had positive serologic tests. Sheep were found to have antibody titers to bovine respiratory syncytial virus, Johne's disease, leptospirosis, and parainfluenza-3. There was no apparent difference in external appearance or condition, or statistical difference in blood test values, between the animals that were positive or negative for parasite ova.

- Abstract
Chemical analyses returned by Mars Pathfinder indicate that some rocks may be high in silica, implying differentiated parent materials. Rounded pebbles and cobbles and a possible conglomerate suggest fluvial processes that imply liquid water in equilibrium with the atmosphere and thus a warmer and wetter past. The moment of inertia indicates a central metallic core of 1300 to 2000 kilometers in radius. Composite airborne dust particles appear magnetized by freeze-dried maghemite stain or cement that may have been leached from crustal materials by an active hydrologic cycle. Remote-sensing data at a scale of generally greater than approximately 1 kilometer and an Earth analog correctly predicted a rocky plain safe for landing and roving with a variety of rocks deposited by catastrophic floods that are relatively dust-free.

As part of ongoing ecological studies of black-faced impala (Aepyceros melampus petersi) in northern Namibia, blood samples were collected and analyzed from 26 animals captured for translocation in 1992. All animals appeared to be in good condition and no abnormality was noted during physical examination. Serum chemistry and mineral levels were measured and correlated with the results of bacterial and viral serology and were within the normal ranges for domestic ruminants. Antibody titers for infectious bovine rhinotracheitis and bovine viral diarrhea were detected. Serological tests for bluetongue, foot-and-mouth disease, rinderpest, parainfluenza 3, brucellosis, leptospirosis, and anaplasmosis were negative. Significant differences in disease prevalence were not found between sexes.

- Abstract
As part of ongoing ecological studies and reproduction enhancement efforts for macaws in southwestern Peru, a health survey of parent- and hand-reared scarlet macaws (Ara macao) and blue and gold macaws (Ara ararauna) was conducted in 1994. Thirty-three birds were examined during handling procedures, and blood samples were collected from 27 (9 parent reared, 18 hand reared) for laboratory analysis. All but one bird appeared to be in good condition, with no abnormality noted during physical examination. Hematology, plasma chemistries, and plasma vitamin and mineral levels were studied and correlated with the results of bacterial and viral serology. Positive antibody titers for Salmonella and psittacine herpesvirus were found. These diseases have the potential to affect wildlife population dynamics, and Salmonella may have public health significance. Serological tests for avian influenza, infectious laryngotracheitis, paramyxovirus-1, -2, -3, polyoma virus, chlamydiosis, and aspergillosis were negative. Differences in disease prevalence were found between rearing situations.

- Abstract
Cytochrome c oxidase subunit II (COXII) in yeast mitochondria is synthesized as a precursor (preCOXII) and is sorted across the inner membrane, whereby both N and C termini become exposed to the intermembrane space. We describe here how this process can be experimentally dissected into a number of distinct stages. Our results demonstrate that the translation of COXII is not obligatorily coupled to translocation. Insertion into the inner membrane and export of the N- and C-terminal domains require an energized inner membrane. The export of COXII is independent of both maturation by the Imp1p protease and assembly into the cytochrome c oxidase complex. When linked to a mitochondrial matrix-targeting sequence, the N-terminal portion of preCOXII (fused to mouse dihydrofolate reductase) can be imported into the mitochondrial matrix. Following accumulation in the matrix, this chimeric protein can become exported across the inner membrane, delivering the N terminus into the intermembrane space where it undergoes processing by the Imp1p protease. This export process displays a number of similarities to bacterial protein export and supports the view that the principles of sorting are conserved from prokaryotes to eukaryotic organelles.

- Abstract
The coraco-clavicular joint is a true synovial joint that may become painful in some patients after trauma. Among the descriptions of this entity is the assertion that the coraco-clavicular joint is routinely seen in gorillas and gibbons. We undertook to assess the incidence of this variant among gorillas, gibbons, and other non-human primates. All available radiographs of large primates performed at the International Wildlife Conservation Park/Bronx Zoo (IWCP) over the past 10 years were reviewed by a musculoskeletal radiologist (human radiology). All radiographs were taken during the normal clinical care of the non-human primate population of the IWCP and are a part of each animal's clinical record. Eighty-one non-human primate radiographs were suitable for study as they contained the region of interest. The 81 radiographic examinations included 14 different species of non-human primates. The coraco-clavicular joint was seen in 4 out of 9 silver-leaf langur, 2 out of 8 lowland gorilla, and in 1 out of 6 white-handed gibbon. In all non-human primate cases where the coraco-clavicular joint occurred, it was bilateral. In 1 out of 8 mandrill, there were very wide distal clavicular ends that articulated both with the coracoid and with the acromion. The coraco-clavicular joint differs from an ossified coraco-clavicular ligament. The radiographic appearance is characteristic and is found in both humans and some non-human primate species. It may rarely become painful following trauma. When symptomatic in humans, resection of this anomalous articulation is curative.

- Abstract
We performed antifungal susceptibility tests with cilofungin (LY121019), amphotericin B, and flucytosine against 38 strains of yeasts from patients with esophagitis or fungemia either before, during, or after treatment with cilofungin. Tests were performed using a macrobroth dilution method similar to that proposed by the National Committee for Clinical Laboratory Standards (M27-P) and two microbroth methods. For cilofungin and amphotericin B, minimum inhibitory concentrations from microbroth tests using Antibiotic Medium 3 (AM3) were systematically lower than results from the other two methods that utilized RPMI-1640 medium (RPMI). AM3 did not provide any greater degree of in vitro correlation with clinical results than did RPMI. We conclude that cilofungin and possibly other congeners of the echinocandin class of antifungal agents can effectively be studied using the proposed National Committee for Clinical Laboratory Standards method.
