Abstract
PURPOSE Physical activity (PA) and body fat percentage (%BF) are independently associated with arterial stiffness, but it has not been explored if there is an associative pathway among these variables. This study examined whether %BF mediates the relationship between PA or sedentary behavior levels with arterial stiffness. METHODS Fifty adults (1:1 men:women; age 28 ± 11 year) had carotid-femoral pulse wave velocity (CF-PWV) measured by applanation tonometry, %BF by bioelectrical impedance, and PA levels by accelerometry. Accelerometer data determined minutes per day spent in sedentary, light, moderate-to-vigorous physical activity (MVPA), and Total PA. RESULTS Pearson correlation indicated statistically significant associations among age, %BF, CF-PWV, MVPA, and Total PA (r = 0.34-0.65, p < 0.05). Sedentary and light PA were not associated with CF-PWV. Mediation analysis indicated significant total effects of MVPA (β = - 0.34, p = 0.044) and age (β = 0.65, p < 0.001) on CF-PWV. %BF mediated the relationship between Total PA and CF-PWV due to indirect effect of Total PA on %BF (β = - 0.34, p = 0.02) and %BF on CF-PWV (β = 0.44, p = 0.002), and partially mediated the relationship between age and CF-PWV (β = 0.54, p < 0.001). Total PA retained its significant effect on %BF (β = - 0.28, p = 0.04) and the effect of %BF on CF-PWV remained significant (β = 0.26, p = 0.03), despite age having a significant effect on both %BF (β = 0.31, p = 0.023) and CF-PWV (β = 0.54, p < 0.001). CONCLUSIONS %BF mediated the relationship between Total PA and arterial stiffness, even after accounting for age. Engagement in more Total PA may help to reduce %BF, resulting in decreased arterial stiffness.

Abstract
Pleuropulmonary blastoma is a rare childhood malignancy of lung mesenchymal cells that can remain dormant as epithelial cysts or progress to high-grade sarcoma. Predisposing germline loss-of-function DICER1 variants have been described. We sought to uncover additional contributors through whole exome sequencing of 15 tumor/normal pairs, followed by targeted resequencing, miRNA analysis and immunohistochemical analysis of additional tumors. In addition to frequent biallelic loss of TP53 and mutations of NRAS or BRAF in some cases, each case had compound disruption of DICER1: a germline (12 cases) or somatic (3 cases) loss-of-function variant plus a somatic missense mutation in the RNase IIIb domain. 5p-Derived microRNA (miRNA) transcripts retained abnormal precursor miRNA loop sequences normally removed by DICER1. This work both defines a genetic interaction landscape with DICER1 mutation and provides evidence for alteration in miRNA transcripts as a consequence of DICER1 disruption in cancer.

Abstract
BACKGROUND Comprehensive molecular characterization of cancer that has metastasized to bone has proved challenging, which may limit the diagnostic and potential therapeutic opportunities for patients with bone-only metastatic disease. METHODS We describe successful tissue acquisition, DNA extraction, and whole-exome sequencing from a bone metastasis of a patient with metastatic, castration-resistant prostate cancer (PCa). RESULTS The resulting high-quality tumor sequencing identified plausibly actionable somatic genomic alterations that dysregulate the phosphoinostide 3-kinase pathway, as well as a theoretically actionable germline variant in the BRCA2 gene. CONCLUSIONS We demonstrate the feasibility of diagnostic bone metastases profiling and analysis that will be required for the widespread application of prospective 'precision medicine' to men with advanced PCa.

Abstract
The ability of cancer to evolve and adapt is a principal challenge to therapy in general and to the paradigm of targeted therapy in particular. This ability is fueled by the co-existence of multiple, genetically heterogeneous subpopulations within the cancer cell population. Increasing evidence has supported the idea that these subpopulations are selected in a Darwinian fashion, by which the genetic landscape of the tumor is continuously reshaped. Massively parallel sequencing has enabled a recent surge in our ability to study this process, adding to previous efforts using cytogenetic methods and targeted sequencing. Altogether, these studies reveal the complex evolutionary trajectories occurring across individual hematological malignancies. They also suggest that while clonal evolution may contribute to resistance to therapy, treatment may also hasten the evolutionary process. New insights into this process challenge us to understand the impact of treatment on clonal evolution and inspire the development of novel prognostic and therapeutic strategies.

Abstract
Pyrocarbon arthroplasty of the proximal interphalangeal joint is a relatively new concept. Early studies have been encouraging, reporting improved pain and function, but a largely unchanged arc of motion. Subsidence of the implant is common, but how it relates to outcome has not been analyzed. This study was performed to review the results of 57 pyrocarbon proximal interphalangeal implanted joints. Results showed a statistically significant increase in the arc of motion, excellent pain relief, and improved function. Subsidence was observed on radiographs in 40% of joints, but no correlation was found compared with arc of motion or function. The incidence of complications is fairly high and usually related to the peri-articular soft tissues, but they are usually minor and do not require further treatment. From this review, we can recommend the use of this implant for treatment of arthritis of the proximal interphalangeal joint.

Abstract
The National Park Service has developed a long-term ecological monitoring program for 32 ecoregional networks containing more than 270 parks with significant natural resources. The monitoring program assists park managers in developing a broad-based understanding of the status and trends of park resources as a basis for making decisions and working with other agencies and the public for the long-term protection of park ecosystems. We found that the basic steps involved in planning and designing a long-term ecological monitoring program were the same for a range of ecological systems including coral reefs, deserts, arctic tundra, prairie grasslands, caves, and tropical rainforests. These steps involve (1) clearly defining goals and objectives, (2) compiling and summarizing existing information, (3) developing conceptual models, (4) prioritizing and selecting indicators, (5) developing an overall sampling design, (6) developing monitoring protocols, and (7) establishing data management, analysis, and reporting procedures. The broad-based, scientifically sound information obtained through this systems-based monitoring program will have multiple applications for management decision-making, research, education, and promoting public understanding of park resources. When combined with an effective education program, monitoring results can contribute not only to park issues, but also to larger quality-of-life issues that affect surrounding communities and can contribute significantly to the environmental health of the nation.

Abstract
We studied the expression of polycomb group (PcG) protein BMI-1 in a large population-based patient series of endometrial carcinomas in relation to clinical and molecular phenotype. Also, 57 fresh frozen endometrial carcinomas were studied for the relationship between BMI-1 protein expression, BMI-1 mRNA level, and activation of an 11-gene signature reported to represent a BMI-1-driven pathway. BMI-1 protein expression was significantly weaker in tumours with vascular invasion (P<0.0001), deep myometrial infiltration (P=0.004), and loss of oestrogen receptor (ER) (P<0.0001) and progesterone receptors (PR) (P=0.03). Low BMI-1 protein expression was highly associated with low BMI-1 mRNA expression (P=0.002), and similarly low BMI-1 mRNA expression correlated significantly with vascular invasion, ER and PR loss, and histologic grade 3. In contrast, activation of the reported 11-gene signature, supposed to represent a BMI-1-driven pathway, correlated with low mRNA expression of BMI-1 (P<0.001), hormone receptor loss, presence of vascular invasion, and poor prognosis. We conclude that BMI-1 protein and mRNA expression are significantly correlated and that BMI-1 expression is inversely associated with activation of the 11-gene signature. Loss of BMI-1 seems to be associated with an aggressive phenotype in endometrial carcinomas.

Abstract
We investigated the effect of endurance training on whole body substrate, glucose, and glycerol utilization during 90 min of exercise at 60% peak O2 consumption (VO2(peak)) in males and females. Substrate oxidation was determined before and after 7 wk of endurance training on a cycle ergometer, with posttesting performed at the same absolute (ABS, W) and relative (REL, VO2(peak)) intensities. [6,6-2H]glucose and [1,1,2,3,3-2H]glycerol tracers were used to calculate the respective substrate tracee flux. Endurance training resulted in an increase in VO2(peak) for both males and females of 17 and 22%, respectively (P < 0.001). Females demonstrated a lower respiratory exchange ratio (RER) both pretraining and posttraining compared with males during exercise (P < 0.001). Glucose rate of appearance (R(a)) and rate of disappearance (R(d)) were not different between males and females. Glucose metabolic clearance rate (MCR) was lower at 75 and 90 min of exercise for females compared with males (P < 0.05). Glucose R(a) and R(d) were lower during exercise at both ABS and REL posttraining exercise intensities compared with pretraining (P < 0.001). Females had a higher exercise glycerol R(a) and R(d) compared with males both pre- and posttraining (P < 0.001). Glycerol R(a) was not different at either the ABS or REL posttraining exercise intensities compared with pretraining. We concluded that females oxidize proportionately more lipid and less carbohydrate during exercise compared with males both pre- and posttraining, which was cotemporal with a higher glycerol R(a) in females. Furthermore, endurance training resulted in a decrease in glucose flux at both ABS and REL exercise intensities after endurance exercise training.

Abstract
Gender differences in substrate selection have been reported during endurance exercise. To date, no studies have looked at muscle enzyme adaptations following endurance exercise training in both genders. We investigated the effect of a 7-week endurance exercise training program on the activity of β-oxidation, tricarboxylic acid cycle and electron transport chain enzymes, and fiber type distribution in males and females. Training resulted in an increase in [Formula: see text]O2peak for both males and females of 17% and 22%, respectively (P < 0.001). The following muscle enzyme activities increased similarly in both genders: 3-β-hydroxyacyl CoA dehydrogenase (38%), citrate synthase (41%), succinate-cytochrome c oxidoreductase (41%), and cytochrome c oxidase (COX; 26%). The increase in COX activity was correlated (R2 = 0.52, P < 0.05) with the increase in [Formula: see text]O2peak/ fat free mass. Fiber area, size, and % area were not affected by training for either gender, however, males had larger Type II fibers (P < 0.05) and females had a greater Type I fiber % area (P < 0.05). Endurance training resulted in similar increases in skeletal muscle oxidative potential for both males and females. Training did not affect fiber type distribution or size in either gender.Key words: endurance training, oxidative potential, gender.

Abstract
We studied the effects of a 38-day endurance exercise training program on leucine turnover and substrate metabolism during a 90-min exercise bout at 60% peak O(2) consumption (VO(2 peak)) in 6 males and 6 females. Subjects were studied at both the same absolute (ABS) and relative (REL) exercise intensities posttraining. Training resulted in a significant increase in whole body VO(2 peak) and skeletal muscle citrate synthase (CS; P < 0.001), complex I-III (P < 0.05), and total branched-chain 2-oxoacid dehydrogenase (BCOAD; P < 0.001) activities. Leucine oxidation increased during exercise for the pretraining trial (PRE, P < 0.001); however, there was no increase for either the ABS or REL posttraining trial. Leucine oxidation was significantly lower for females at all time points during rest and exercise (P < 0.01). The percentage of BCOAD in the activated state was significantly increased after exercise for both the PRE and REL exercise trials, with the increase in PRE being greater (P < 0.001) compared with REL (P < 0.05). Females oxidized proportionately more lipid and less carbohydrate during exercise compared with males. In conclusion, we found that 38 days of endurance exercise training significantly attenuated both leucine oxidation and BCOAD activation during 90 min of endurance exercise at 60% VO(2 peak) for both ABS and REL exercise intensities. Furthermore, females oxidize proportionately more lipid and less carbohydrate compared with males during endurance exercise.

Abstract
In May 1996, the Georgia Division of Public Health was notified about a cluster of persons with Salmonella Enteritidis (SE) infections in Waycross, Georgia. A matched pair case-control study to determine risk factors for illness found a statistically significant association of SE infection with a history of having eaten at Restaurant A during the 5 days before onset of illness (relative risk = 13 [95% confidence interval (CI) = 3-62, P < 0.01]). In a second case-control study, to determine specific food exposures, consumption of a deep-fried Mexican dish (chile relleno) (4 of 21 cases vs. 0 of 26 controls, odds ratio undefined, 95% CI > 1.46, P = 0.034) was found to be significantly associated with SE infection. An environmental investigation found evidence of suboptimal food storage and cooking temperatures at Restaurant A; cross contamination of foods may have contributed to the low attributable risk identified for chile rellenos. Five of 37 Restaurant A food and environment specimens yielded SE strains. All five positive specimens were from chiles rellenos. Of the seven outbreak-associated strains (six patient isolates and one food isolate from Restaurant A) for which phage typing was conducted, all were phage type 34. A FDA traceback investigation through Restaurant A's single-egg supplier identified the potential source as three interrelated farms in South Carolina. Environmental culture from one of these farms yielded SE phage type 34. As a result of this outbreak, FDA helped institute a statewide egg quality-assurance programme in South Carolina to minimize SE contamination of eggs.

Abstract
In 1995, the National Heart Lung and Blood Institute (NHLBI) solicited requests for a proposal (RFP) entitled "Transplant Centers for Clinical Research on Transplantation of Umbilical Cord Stem and Progenitor Cells." Three banks, six transplant centers, and one medical coordinating center (MCC) (Table 1) were funded with the overall goal of banking cord blood units (CBU) using a single manual of operations. Furthermore, the clinical protocols to evaluate the transplant outcome for adult and pediatric recipients of these well-characterized CBU would be analyzed in a uniform fashion. Because of the intense interest of the transplantation community in the policies and procedures for cord blood collection and processing, the principal investigators of the cord blood banks (CBB) and NHLBI elected to submit for publication the rationale and an abridged, but detailed, version of the standard operating procedures (SOP) developed between October 1996 and July 1998 prior to the initiation of the clinical protocols to be performed with these CBU. As the SOP will be refined over time, the complete SOP and subsequent amendments will be published and continually updated on the websites from the MCC-The EMMES Corporation (www.EMMES.com). All forms referred to in this document may be obtained from the EMMES website. It is hoped that the publication of this document will lay down a framework that will not only facilitate the development of other CBB but also help us more rapidly define what constitutes an "acceptable" CBU product.

Abstract
Chromosome 11 is frequently altered in several types of human neoplasms. In breast cancer, loss of heterozygosity has been described in two regions of this chromosome, 11p15 and 11q22-23. In this report we have dissected the two regions using high-density polymorphic markers, and have found that there are at least two independent areas of loss of heterozygosity in each region, suggesting that multiple genes on chromosome 11 may be targets of genetic alteration during tumor establishment or progression. The regions defined are: at 11p15, between loci D11S576 and D11S1318 and between D11S988 and D11S1318; at 11q23, between D11S2000 and D11S897 and between D11S528 and D11S990. The narrowing of these regions of loss should facilitate the cloning of the regions in yeast artificial chromosomes to identify the critical tumor suppressor genes.

Abstract
The short arm of chromosome 1 is frequently affected by rearrangements in a variety of human malignancies. Genetic alterations, predominantly deletions, which are indicative of the presence of a putative tumor suppressor gene at chromosome 1p, are observed in breast cancer. In order to define the altered locus, eleven highly polymorphic microsatellite markers on chromosome 1p were used to detect loss of heterozygosity. We analyzed 52 cases of breast cancer and found 4 common deleted regions at chromosome 1p. Twenty-two of 52 (42%) informative patients showed at least 1 affected locus. The region most frequently exhibiting loss of heterozygosity was 1p31 (11/39; 28%); the other three common deleted regions were 1p36 (10/44; 23%), 1p35-36 (5/40; 13%), and 1p13 (8/39; 21%). These data suggest that one or more putative tumor suppressor genes may reside on chromosome 1p. We have cloned the entire region of interest at 1p31 in yeast artificial chromosomes. This yeast artificial chromosome contig can be used for fine mapping of the region and cloning of the candidate tumor suppressor gene.

Abstract
Studies of loss of heterozygosity (LOH) in breast tumor DNA suggest that several tumor suppressor genes participate in the pathogenesis of breast cancer. Although the short arm of chromosome 11 has been implicated in breast cancer development, no previous LOH studies have indicated the involvement of a suppressor gene on 11q in breast carcinoma. To this end, tumor samples and corresponding normal tissue were collected from 62 unselected patients with primary breast cancer, and the extracted DNA was analyzed by polymerase chain reaction using microsatellite markers on chromosome 11. We found that 39% of the tumors (22 of 57 informative cases) revealed allelic loss in the region 11q22-23, and this loss was independent of LOH found to occur on 11p15. Interestingly, more than 90% of the tumors showed concordant loss of alleles at both 11q and 17p. The marker D11S528, showing LOH in 39% of informative cases, had the highest frequency of LOH among the markers that were used. The data presented indicate that the common overlapping region of LOH is between the loci D11S35 and D11S29, suggesting that this area contains a tumor suppressor gene frequently lost in breast cancer.

Abstract
Rearrangements of the ALL-1 gene by reciprocal translocations involving chromosome band 11q23 are frequently associated with human acute leukemia. We have previously reported the detection of ALL-1 gene rearrangements in adult patients with acute myeloid leukemia lacking cytogenetic evidence of 11q23 translocations. These included 2 of 19 patients with normal karyotypes as well as 3 of 4 patients with trisomy 11 as a sole cytogenetic abnormality. Rearrangement of the ALL-1 genes in two of the patients with trisomy 11 was shown to result from a direct tandem duplication of a portion of the gene spanning exons 2-6. Here we report the characterization of the ALL-1 gene rearrangement in one of the previously reported acute myeloid leukemia patients with a normal karyotype. ALL-1 rearrangement in this patient results from a direct tandem duplication of a portion of the gene spanning exons 2-8. RNA polymerase chain reaction and DNA sequence analysis show that the partially duplicated ALL-1 gene is transcribed into mRNA capable of encoding a partially duplicated protein. Sequence analysis of the genomic fusion region provides evidence for Alu-mediated homologous recombination as a mechanism for partial duplication of the ALL-1 gene.

Abstract
A thematic analysis of 30 narrative accounts of bereavement revealed nine themes that included five core themes in bereavement--being stopped, hurting, missing, holding, and seeking; three meta-themes about bereavement--change, expectations, and inexpressibility; and a contextual theme--personal history. The themes were compared with three theoretical perspectives on bereavement by Freud, Kübler-Ross, and one defined as existential-phenomenological. Features of bereavement that are dissimilar or unaddressed by the theoretical perspectives were: (a) the quality of grief's changing character, including "waves" and intense pain which may be triggered years after the death; (b) holding, an individual process of preserving the fact and meaning of the loved one's existence; (c) expectations, both social and personal, as to how the bereaved should be overlaying the experience; and (d) the critical importance of personal history in affecting the quality and meaning of individual bereavement.

Abstract
The interactions between yohimbine (selective alpha 2-antagonist) with noradrenaline (mixed agonist) and phenylephrine (selective alpha 1-agonist) were studied in the canine dorsal pedal artery in an attempt to characterize the peripheral vascular response to adrenergic agents before and after the development of congestive heart failure in the dog. The contractile responses of the dorsal pedal artery to potassium chloride were also examined. Both noradrenaline and phenylephrine contracted the dorsal pedal artery in a concentration-dependent manner before and at peak heart failure, the responses to the agonists being enhanced at heart failure. The responses of the artery to potassium were not modified by congestive heart failure. Yohimbine caused concentration-dependent antagonism of noradrenaline, without altering the magnitude of the maximum response, providing pA2 values ranging from 8.26 to 7.06 against low and high concentrations of noradrenaline, respectively, before heart failure development. Following heart failure, the pA2 values for yohimbine against noradrenaline remained unchanged, but slopes from the Arunlakshana-Schild plots were significantly different from unity, implying a noncompetitive antagonism. The pA2 values of yohimbine against phenylephrine were at least 10 orders of magnitude lower than those against noradrenaline. After congestive heart failure, yohimbine was even less effective against high concentrations of phenylephrine. These findings suggest that enhanced vasoconstriction during heart failure results, in part, from increased alpha 1-adrenoceptor mechanisms in peripheral arterial smooth muscle.

Abstract
Rocky Mountain spotted fever is a serious acute systemic illness frequently complicated by cardiac involvement. To evaluate the spectrum of myocardial dysfunction, we obtained M-mode echocardiograms on nine consecutive patients with Rocky Mountain spotted fever within 72 hours of admission. Seven of the nine patients had echocardiographic evidence of impaired left ventricular function; two of the seven had no other evidence of cardiac involvement. The extent of impairment of left ventricular function reflected the clinical severity of the illness. Left ventricular myocardial dysfunction is a frequent complication of Rocky Mountain spotted fever. Echocardiography may provide the only clinical evidence of cardiac involvement in these patients.

Abstract
An indirect fluorescent antibody (IFA) technique was developed to detect IgG and IgM-specific antibodies to Mycoplasma pneumoniae. The presence of IgM-specific mycoplasma antibody was interpreted as reflecting active infection in patients with atypical pneumonia or other clinically compatible illness. The procedure is suitable for use in routine clinical laboratories, correlated well with complement fixation test results and did not show cross reaction with Legionella pneumophila antibody. The ready availability of an acute-phase procedure for diagnosis of Mycoplasma pneumoniae infection permits therapeutic judgments based on testing of the acute serum sample.

Abstract
A 60-year-old man treated with a prothesis for aorto-enteric fistulae developed multicentric osteomyelitis. Enteric flora were cultured from blood and bone but the diagnosis was delayed. Aorto-enteric fistulae can occur in a variety of circumstances but have become more common with the advent of reconstructive vascular surgery using prostheses. This entity frequently does not present in a dramatic way, but can be the cause of fatal bacteremia and septicemia.
