Abstract
OBJECTIVE There are variable reports of risk of concordance for progression to islet autoantibodies and type 1 diabetes in identical twins after one twin is diagnosed. We examined development of positive autoantibodies and type 1 diabetes and the effects of genetic factors and common environment on autoantibody positivity in identical twins, nonidentical twins, and full siblings. RESEARCH DESIGN AND METHODS Subjects from the TrialNet Pathway to Prevention Study (N = 48,026) were screened from 2004 to 2015 for islet autoantibodies (GAD antibody [GADA], insulinoma-associated antigen 2 [IA-2A], and autoantibodies against insulin [IAA]). Of these subjects, 17,226 (157 identical twins, 283 nonidentical twins, and 16,786 full siblings) were followed for autoantibody positivity or type 1 diabetes for a median of 2.1 years. RESULTS At screening, identical twins were more likely to have positive GADA, IA-2A, and IAA than nonidentical twins or full siblings (all P < 0.0001). Younger age, male sex, and genetic factors were significant factors for expression of IA-2A, IAA, one or more positive autoantibodies, and two or more positive autoantibodies (all P ≤ 0.03). Initially autoantibody-positive identical twins had a 69% risk of diabetes by 3 years compared with 1.5% for initially autoantibody-negative identical twins. In nonidentical twins, type 1 diabetes risk by 3 years was 72% for initially multiple autoantibody-positive, 13% for single autoantibody-positive, and 0% for initially autoantibody-negative nonidentical twins. Full siblings had a 3-year type 1 diabetes risk of 47% for multiple autoantibody-positive, 12% for single autoantibody-positive, and 0.5% for initially autoantibody-negative subjects. CONCLUSIONS Risk of type 1 diabetes at 3 years is high for initially multiple and single autoantibody-positive identical twins and multiple autoantibody-positive nonidentical twins. Genetic predisposition, age, and male sex are significant risk factors for development of positive autoantibodies in twins.

Abstract
OBJECTIVE We tested the ability of a type 1 diabetes (T1D) genetic risk score (GRS) to predict progression of islet autoimmunity and T1D in at-risk individuals. RESEARCH DESIGN AND METHODS We studied the 1,244 TrialNet Pathway to Prevention study participants (T1D patients' relatives without diabetes and with one or more positive autoantibodies) who were genotyped with Illumina ImmunoChip (median [range] age at initial autoantibody determination 11.1 years [1.2-51.8], 48% male, 80.5% non-Hispanic white, median follow-up 5.4 years). Of 291 participants with a single positive autoantibody at screening, 157 converted to multiple autoantibody positivity and 55 developed diabetes. Of 953 participants with multiple positive autoantibodies at screening, 419 developed diabetes. We calculated the T1D GRS from 30 T1D-associated single nucleotide polymorphisms. We used multivariable Cox regression models, time-dependent receiver operating characteristic curves, and area under the curve (AUC) measures to evaluate prognostic utility of T1D GRS, age, sex, Diabetes Prevention Trial-Type 1 (DPT-1) Risk Score, positive autoantibody number or type, HLA DR3/DR4-DQ8 status, and race/ethnicity. We used recursive partitioning analyses to identify cut points in continuous variables. RESULTS Higher T1D GRS significantly increased the rate of progression to T1D adjusting for DPT-1 Risk Score, age, number of positive autoantibodies, sex, and ethnicity (hazard ratio [HR] 1.29 for a 0.05 increase, 95% CI 1.06-1.6; P = 0.011). Progression to T1D was best predicted by a combined model with GRS, number of positive autoantibodies, DPT-1 Risk Score, and age (7-year time-integrated AUC = 0.79, 5-year AUC = 0.73). Higher GRS was significantly associated with increased progression rate from single to multiple positive autoantibodies after adjusting for age, autoantibody type, ethnicity, and sex (HR 2.27 for GRS >0.295, 95% CI 1.47-3.51; P = 0.0002). CONCLUSIONS The T1D GRS independently predicts progression to T1D and improves prediction along T1D stages in autoantibody-positive relatives.

Abstract
An increased serum alkaline phosphatase concentration is known to be associated with a negative prognosis in canine and human osteosarcoma. To expand upon previous studies regarding the biological relevance of increased serum alkaline phosphatase as a negative prognostic factor, xenogeneic heterotopic transplants were performed using six canine primary osteosarcoma cell lines generated from patients with differing serum alkaline phosphatase concentrations (three normal and three increased). Three of the six cell lines were capable of generating tumours and tumour formation was independent of the serum alkaline phosphatase status of the cell line. Microarray analysis identified 379 genes as being differentially expressed between the tumourigenic and non-tumourigenic cell lines. Frizzled-6 was upregulated to the greatest extent (7.78-fold) in tumourigenic cell lines compared with non-tumourigenic cell lines. Frizzled-6, a co-receptor for Wnt ligands has been associated with enhanced tumour-initiating cells and poor prognosis for other tumours. The increased expression of frizzled-6 was confirmed by quantitative reverse transcription polymerase chain reaction (QPCR) and Western blot analysis. Additionally, the tumourigenic cell lines also had an increase in the percentage of side population cells compared with non-tumourigenic cell lines (5.89% versus 1.58%, respectively). There were no differences in tumourigenicity, frizzled-6 or percentage of side population cells noted between osteosarcoma cell lines generated from patients of differing serum alkaline phosphatase concentration. However, to our knowledge this is the first study to identified frizzled-6 as a possible marker of osteosarcoma cell populations with enhanced tumourigenicity and side population cells. Future work will focus on defining the role of frizzled-6 in osteosarcoma tumourigenesis and tumour-initiating cells.

Abstract
Serum alkaline phosphatase (ALP) concentration is a prognostic factor for osteosarcoma in multiple studies, although its biological significance remains incompletely understood. To determine whether gene expression patterns differed in osteosarcoma from patients with differing serum ALP concentrations, microarray analysis was performed on 18 primary osteosarcoma samples and six osteosarcoma cell lines from dogs with normal and increased serum ALP concentration. No differences in gene expression patterns were noted between tumours or cell lines with differing serum ALP concentration using a gene-specific two-sample t-test. Using a more sensitive empirical Bayes procedure, defective in cullin neddylation 1 domain containing 1 (DCUN1D1) was increased in both the tissue and cell lines of the normal ALP group. Using quantitative PCR (qPCR), differences in DCUN1D1 expression between the two groups failed to reach significance. The homogeneity of gene expression patterns of osteosarcoma associated differing serum ALP concentrations are consistent with previous studies suggesting serum ALP concentration is not associated with intrinsic differences of osteosarcoma cells.

Abstract
PURPOSE To evaluate the effects of oral N-acetylcysteine (NAC), which replenishes systemic glutathione, on decreasing inflammation and improving lung function in CF airways. METHODS A multicenter, randomized, double-blind proof of concept study in which 70 CF subjects received NAC or placebo orally thrice daily for 24 weeks. ENDPOINTS primary, change in sputum human neutrophil elastase (HNE) activity; secondary, FEV(1) and other clinical lung function measures; and safety, the safety and tolerability of NAC and the potential of NAC to promote pulmonary hypertension in subjects with CF. RESULTS Lung function (FEV(1) and FEF(25-75%)) remained stable or increased slightly in the NAC group but decreased in the placebo group (p=0.02 and 0.02). Log(10) HNE activity remained equal between cohorts (difference 0.21, 95% CI -0.07 to 0.48, p=0.14). CONCLUSIONS NAC recipients maintained their lung function while placebo recipients declined (24 week FEV1 treatment effect=150 mL, p<0.02). However no effect on HNE activity and other selected biomarkers of neutrophilic inflammation were detected. Further studies on mechanism and clinical outcomes are warranted.

Abstract
Osteosarcoma is an aggressive malignancy and represents the most frequent primary bone malignancy of dogs and humans. Prognostic factors reported for osteosarcoma include tumour size, presence of metastatic disease and serum alkaline phosphatase (ALP) concentration at the time of diagnosis. To date, there have been no studies to determine whether the behaviour of osteosarcoma cells differ based on serum ALP concentration. Here, we report on the generation of six canine osteosarcoma cell lines from osteosarcoma-bearing dogs with differences in serum ALP concentration. To determine whether in vitro behaviour differs between primary osteosarcoma cell lines generated from patients with normal or increased serum ALP, assays were performed to evaluate proliferation, migration, invasion and chemosensitivity. There were no significant differences in cell proliferation, migration, invasion or chemosensitivity between cell lines associated with normal or increased serum ALP concentration.

Abstract
Canine malignant melanoma is a highly aggressive tumour associated with a poor overall survival rate due to both local disease recurrence and its highly metastatic nature. Similar to advanced melanoma in man, canine oral melanoma is poorly responsive to conventional anti-cancer therapies. The lack of sustainable disease control warrants investigation of novel therapies, preferably targeting features specific to the tumour and different from normal cells. The Wnt signalling pathway is known to contribute to melanocytic lineage development in vertebrates and perturbation of the Wnt/β-catenin pathway has been implicated in numerous cancer types. Alterations of the Wnt/β-catenin pathway are suggested to occur in a subset of human melanomas, although the precise role of the Wnt/β-catenin pathway in melanoma is yet to be defined. This study investigates the activation status of the canonical Wnt/β-catenin pathway in canine malignant melanoma and its potential as a therapeutic target for treating this disease. The data indicate that canonical Wnt/β-catenin pathway activation is a rare event in canine oral malignant melanoma tissue and canine malignant melanoma cell lines.

Abstract
Osteosarcoma (OSA) is the most frequently occurring malignant primary bone tumour in dogs and children and arises from cells of the osteoblast lineage. Inappropriate Wnt signalling activity has been implicated in human OSA. Altered expression of β-catenin, an integral member of the Wnt signalling pathway, has been associated with numerous human cancers, including OSA. In this study, 30 of the 37 primary canine OSA tissues and 2 of the 3 metastatic OSAs were positive for β-catenin expression as determined by immunohistochemistry, whereas 2 normal bones stained negative for β-catenin. No mutations were identified in exon 3 of β-catenin in the three OSA cases in which DNA sequencing was performed. Finally, there was no relationship between β-catenin expression and overall survival time or disease-free interval. Our results indicate β-catenin is frequently expressed within the cytoplasm of neoplastic cells in canine OSA but contains no detectable mutations in exon 3, similar to human OSA.

Abstract
The structural integrity of teeth under stress is vital to functional longevity. We tested the hypothesis that this integrity is limited by fracture of the enamel. Experiments were conducted on molar teeth, with a metal rod loaded onto individual cusps. Fracture during testing was tracked with a video camera. Two longitudinal modes of cracking were observed: median cracking from the contact zone, and margin cracking along side walls. Median cracks initiated from plastic damage at the contact site, at first growing slowly and then accelerating to the tooth margin. Margin cracks appeared to originate from the cemento-enamel junction, and traversed the tooth wall adjacent to the loaded cusp from the gingival to the occlusal surface. All cracks remained confined within the enamel shell up to about 550 N. At higher loads, additional crack modes—such as enamel chipping and delamination—began to manifest themselves, leading to more comprehensive failure of the tooth structure.

Abstract
This paper considers the use of bioinspired functionally graded structures in the design of dental multi-layers that are more resistant to sub-surface crack nucleation. Unlike existing dental crown restorations that give rise to high stress concentration, the functionally graded layers (between crown materials and the joins that attach them to dentin) are shown to promote significant reductions in stress and improvements in the critical crack size. Special inspiration is drawn from the low stress concentrations associated with the graded distributions in the dentin-enamel-junction (DEJ). The implications of such functionally graded structures are also discussed for the design of dental restorations.

Abstract
Neotropical grass-feeding spittlebugs of several genera are important pests of pasture grasses from the southeastern USA to northern Argentina, and of sugarcane from southern Mexico to southern Brazil, causing estimated reductions of up to 70% in yield and estimated monetary losses of 840-2100 million US dollars annually. With few exceptions, the species badly damaged by these spittlebugs are introduced C4 grasses that exhibit associative nitrogen fixation. This study synthesizes evidence that the pest status of many tropical and subtropical grass-feeding spittlebugs is linked to associative N-fixation in their C4 hosts. Recognition that associative N-fixation is a major factor in spittlebug host preferences should deepen understanding of spittlebug agricultural ecology and facilitate efforts to combat spittlebug pests. In particular, spittlebugs should be susceptible to manipulation of xylem transport solutes. However, reduction of nitrate fertilizer rates, increase in ammonium fertilizer rates, or enhancement of associative N-fixation as a consequence of genetic engineering could make hosts more susceptible to spittlebug attack. Because of their predilection for C4 grasses, spittlebugs present a clear counterexample to the hypothesis that herbivores prefer C3 plants to C4 plants. Finally, it appears that declines in atmospheric carbon dioxide levels during recent geological history promoted the proliferation of C4 grasses. This, compounded by human agricultural activities, has driven an ecological and evolutionary radiation of grass-feeding spittlebugs that presents continuing opportunities for the evolution of spittlebug pests.

Abstract
CONTEXT Persons with recently acquired latent tuberculosis (TB) infection and human immunodeficiency virus (HIV) co-infection are at high risk of rapid progression to TB disease. OBJECTIVES To determine the proportion of close contacts of infectious TB patients tested for HIV, and the results of HIV testing for this group. DESIGN, SETTING AND SUBJECTS Review of health department records for all close contacts of 349 patients with culture-positive pulmonary TB aged 15 years or older reported from five study areas in the United States in 1996. MAIN OUTCOME MEASURES Proportion of close contacts of TB patients tested for HIV, and rate of HIV infection among close contacts of TB patients. RESULTS A total of 1169 close contacts were identified for 349 patients with active pulmonary TB. HIV test results were available for 224 (64%) TB patients and 220 (19%) close contacts. Of the TB patients tested, 164 (73%) were HIV-negative and 60 (27%) were HIV-positive. An equal proportion of close contacts of HIV-positive and -negative TB patients were tested (21% vs. 24%). Of the close contacts tested, 201 (91%) were HIV-negative and 19 (9%) were HIV-positive. Compared with close contacts of HIV-negative TB patients, close contacts of HIV-positive TB patients were more likely to be HIV-positive (53% vs. 2%; P < 0.01). This association was observed for contacts residing in the TB patient household (70% vs. none; P < 0.01), not residing in the TB patient household (20% vs. 4%; P < 0.05), 25-44 years of age (88% vs. 8%; P < 0.01), and > 44 years of age (22% vs. 2%; P < 0.05). CONCLUSIONS HIV-positive TB patients and their close contacts may share some of the same risk factors for HIV infection. These findings suggest that the HIV status of the TB patient, in addition to established risk factors for HIV infection, may be an important consideration for prioritizing voluntary HIV counseling and testing efforts among close contacts of infectious TB patients.

Abstract
SETTING Five state tuberculosis (TB) control programs in the United States. OBJECTIVES To determine the prevalence of and treatment for latent TB infection (LTBI) among contacts of active TB cases identified in the workplace, and to describe TB control program policies for the initiation and conduct of workplace investigations. DESIGN Retrospective review of health department records for all culture-positive pulmonary tuberculosis cases aged > or = 15 years reported in 1996, and their contacts. RESULTS There were 349 cases of active TB, of whom 134 (38%) were employed. Workplace contact investigations were conducted for 42 cases, resulting in the identification of 724 contacts. The rate of LTBI was 29% overall, varying by worksite from a low of 16% to a high of 51%. LTBI estimates were higher for fully-screened contacts of smear-positive rather than of smear-negative index cases. However, fully-screened contacts of index patients with cavitary disease had lower LTBI estimates than those of index patients without cavitation. Treatment for LTBI was initiated in 45% of infected contacts. The five programs had somewhat variable policies regarding workplace contact investigations. Data on HIV co-infection and place of birth of contacts were largely missing. CONCLUSION Factors contributing to LTBI among workplace contacts may include the presence of persons with pre-existing LTBI or a positive skin test as a result of BCG vaccination, clinical characteristics of the index case, and workplace environmental characteristics conducive to transmission. Standard guidelines for workplace investigations, written workplace investigation policies, and standard data collection practices are needed to better apportion the causes of observed infection rates in the workplace.

Abstract
SETTING Homelessness is an important risk factor for tuberculosis (TB). Health departments often fail to identify contacts for homeless TB cases, but little else is known about the outcome of contact investigations for these cases. OBJECTIVE To describe the outcomes of identification, tuberculin skin testing (TST), clinical evaluation and treatment for contacts of infectious homeless TB cases. DESIGN Retrospective multicenter review of data of contact investigations conducted in 1996 by five health departments in the United States. RESULTS Twenty-seven (8%) of 349 TB cases were homeless. Failure to identify contacts occurred in six (50%) of 12 cases residing in shelters vs. one (7%) of 15 non-shelter cases. Of 479 contacts identified, 297 (62%) were fully evaluated, 97 (20%) had only initial testing, and 85 (18%) were not evaluated. Of the 394 evaluated contacts, 13 (3%) had a prior positive TST. Of the remaining 381 contacts, six (1.6%) had active TB and 67 (17.6%) were TST-positive. Only 27 (44%) of 61 contacts completed treatment for latent TB infection. CONCLUSION Despite the failure to identify contacts for some cases, contact investigations for homeless TB cases identified large numbers of contacts for whom evaluation and treatment were often not completed. Prospective studies with more complete documentation are needed to improve contact investigations for homeless TB cases.

Abstract
We have examined the abundance and structure of intermediates in the chondrocyte-mediated degradation of aggrecan by aggrecanase(s). Degradation products were identified by Western-blot analysis with antibodies to cleavage-site neoepitopes and to peptides within the globular domains. Rat chondrosarcoma tumour contained full-length aggrecan and all of the individual peptides expected from single independent cleavages at each of the four aggrecanase sites in the chondroitin sulphate (CS) domain. Kinetic analysis of the products present in rat chondrosarcoma cell cultures treated with interleukin-1b showed that the first aggrecanase-mediated cleavages occurred at the four sites within the CS attachment region to generate two stable intermediates, Val(1)-Glu(1459) and Val(1)-Glu(1274). These species were subsequently cleaved at the Glu(373) site in the interglobular domain to form the terminal products, Val(1)-Glu(373), Ala(374)-Glu(1274) and Ala(374)-Glu(1459). It therefore appears that the aggrecanase-mediated processing of native aggrecan by chondrocytes in situ is initiated within the CS-attachment region and completed by cleavage within the interglobular domain. Since it has been shown that digestion of aggrecan monomer in solution with recombinant ADAMTS-4 [Tortorella, Pratta, Liu, Austin, Ross, Abbaszade, Burn and Arner (2000) Sites of aggrecan cleavage by recombinant human aggrecanase-1 (ADAMTS-4). J. Biol. Chem. 275, 18566-18573] exhibits similar kinetics, it appears that preferential proteinase cleavage in the CS-rich region is determined by properties inherent in the aggrecan monomer itself, such as preferred peptide sequences for enzyme binding or enhanced accessibility to the core protein at these sites.

Abstract
The control of chondrocyte-mediated degradation of aggrecan has been studied in rat chondrosarcoma cells and bovine cartilage explants treated with either IL-1 or retinoic acid. The capacity of glucosamine to inhibit the aggrecanase-mediated response (J. D. Sandy, D. Gamett, V. Thompson, and C. Verscharen (1998) Biochem. J. 335, 59-66) has been extended to an investigation of the effect of other hexosamines. Mannosamine inhibits the aggrecanase response to both IL-1 and RA at about one-tenth the concentration of glucosamine in both rat cell and bovine explant systems. This effect of mannosamine appears to be due to its capacity to inhibit the synthesis of glycosylphosphatidylinositol (GPI)-linked proteins by chondrocytes since the GPI synthesis inhibitor 2-deoxyfluoroglucose (2-DFG) also inhibited the aggrecanase response to IL-1b and RA in rat cells. Moreover, phosphatidylinositol-specific phospholipase C (PIPLC) treatment of rat cells markedly inhibited the aggrecanase response to IL-1b and RA. These inhibitory effects of mannosamine, 2-DFG, and PIPLC in rat cells did not appear to be due to an interference with general biosynthetic activity of the cells as measured by [3H]proline incorporation into secreted proteins. We suggest that the aggrecanase response by chondrocytes to IL-1 and RA is dependent on the activity of a GPI-anchored protein on the chondrocyte cell surface.

Abstract
A rat chondrosarcoma cell line and bovine cartilage explants have been used to study the control of aggrecan degradation by chondrocytes treated with interleukin-1 (IL-1) or retinoic acid (RA). Aggrecan fragment analysis with anti-neo-epitope antibodies suggests that aggrecanase (an as yet unidentified enzyme) is the only aggrecan-degrading proteinase active in these cultures. With rat cells, aggrecanase converts the aggrecan core protein into two major G1-domain-bearing products (60 kDa with a C-terminal Glu-373, and 220 kDa with a C-terminal Glu-1459). Both products were quantified on a standardized Western analysis system with a G1-specific antibody. Immunoblots were analysed by scanning densitometry and the sensitivity, linearity and reproducibility of the assay were established. With rat cells the aggrecanase response to IL-1 was optimal at about 2 mM glutamine, but was progressively inhibited at higher concentrations, with about 90% inhibition at 10 mM glutamine. Such inhibition by glutamine was not, however, observed with bovine explants. On the other hand, marked inhibition of aggrecanase-dependent cleavage was observed with both rat cells and bovine explants when d(+)-glucosamine was included at concentrations above 2 mM. Inhibition was apparently not due to cytotoxicity or interference with IL-1 signalling, since biosynthetic activity was not inhibited and inhibition of the aggrecanase response was also obtained when RA was used as the catabolic stimulator. Possible mechanisms for the inhibition of the aggrecanase response by glucosamine in chondrocytes treated with IL-1 or RA are discussed.

Abstract
PURPOSE The use of escalated radiation doses to improve local control in conformal radiotherapy of prostatic cancer is becoming the focus of many centers. There are, however, increased side effects associated with increased radiotherapy doses that are believed to be dependent on the volume of normal tissue irradiated. For this reason, accurate patient positioning, CT planning with 3D reconstruction of volumes of interest, clear definition of treatment margins and verification of treatment fields are necessary components of the quality control for these procedures. In this study electronic portal images are used to (a) evaluate the magnitude and effect of the setup errors encountered in patient positioning techniques, and (b) verify the multileaf collimator (MLC) field patterns for each of the treatment fields. METHODS AND MATERIALS The Phase I volume, with a planning target volume (PTV) composed of the gross tumour volume (GTV) plus a 1.5 cm margin is treated conformally with a three-field plan (usually an anterior field and two lateral or oblique fields). A Phase II, with no margin around the GTV, is treated using two lateral and four oblique fields. Portal images are acquired and compared to digitally reconstructed radiographs (DRR) and/or simulator films during Phase I to assess the systematic (CT planning or simulator to treatment error) and the daily random errors. The match results from these images are used to correct for the systematic errors, if necessary, and to monitor the time trends and effectiveness of patient imobilization systems used during the Phase I treatment course. For the Phase II, portal images of an anterior and lateral field (larger than the treatment fields) matched to DRRs (or simulator images) are used to verify the isocenter position 1 week before start of Phase II. The Portal images are acquired for all the treatment fields on the first day to verify the MLC field patterns and archived for records. The final distribution of the setup errors was used to calculate modified dose-volume histograms (DVHs). This procedure was carried out on 36 prostate cancer patients, 12 with vacuum-molded (VacFix) bags for immobilization and 24 with no immobilization. RESULTS The systematic errors can be visualized and corrected for before the doses are increased above the conventional levels. The requirement for correction of these errors (e.g., 2.5 mm AP shift) was demonstrated, using DVHs, in the observed 10% increase in rectal volume receiving at least 60 Gy. The random (daily) errors observed showed the need for patient fixation devices when treating with reduced margins. The percentage of fields with displacements of < or = 5.0 mm increased from 82 to 96% with the use of VacFix bags. The rotation of the pelvis is also minimized when the bags are used, with over 95% of the fields with rotations of < or = 2.0 degrees compared to 85% without. Currently, a combination of VacFix and thermoplastic casts is being investigated. CONCLUSION The systematic errors can easily be identified and corrected for in the early stages of the Phase I treatment course. The time trends observed during the course of Phase I in conjunction with the isocenter verification at the start of Phase II give good prediction of the accuracy of the setup during Phase II, where visibility of identifiable structures is reduced in the small fields. The acquisition and inspection of the portal images for the small Phase I fields has been found to be an effective way of keeping a record of the MLC field patterns used. Incorporation of the distribution of the setup errors into the planning system also gives a clearer picture of how the prescribed dose was delivered. This information can be useful in dose-escalation studies in determining the relationship between the local control or morbidity rates and prescribed dose.

Abstract
Loss-of-function mutations in the G4.5 gene have been shown to cause Barth syndrome (BTHS), an X-linked disorder characterized by cardiac and skeletal myopathy, short stature, and neutropenia. We recently reported a family with a severe X-linked cardiomyopathy described as isolated noncompaction of the left ventricular myocardium (INVM). Other findings associated with BTHS (skeletal myopathy, neutropenia, growth retardation, elevated urinary organic acids, and mitochondrial abnormalities) were either absent or inconsistent. A linkage study of the X chromosome localized INVM to the Xq28 region near the BTHS locus, suggesting that these disorders are allelic. We screened the G4.5 gene for mutations in this family with SSCP and direct sequencing and found a novel glycine-to-arginine substitution at position 197. This position is conserved in a homologous Caenorhabditis elegans protein. We conclude that INVM is a severe allelic variant of BTHS with a specific effect on the heart. This finding provides further structure-function information about the G4.5 gene product and has implications for unexplained cases of severe infantile hypertrophic cardiomyopathy in males.

Abstract
This study has evaluated the use of electronic portal imaging (EPI) as a replacement for megavoltage verification films in the treatment of conformal pelvic patients. The two methods of imaging have been compared in 40 patients. Several advantages of EPI were identified, including case of image acquisition. regular assessment of reproducibility of set-up and the possibility of on-line intervention when necessary. The findings suggest that EPI is a suitable replacement for films.

Abstract
PURPOSE The 193-nm argon fluoride excimer laser can remove corneal scars and smooth corneal irregularities, obviating corneal transplantation. We conducted a prospective multicenter trial of excimer laser phototherapeutic keratectomy for corneal vision loss as a basis for Food and Drug Administration premarket approval. METHODS We treated 232 eyes of 211 patients with corneal vision loss. All had corneal pathology in the anterior 100 microns of the stroma. Mean postoperative follow-up was 10 +/- 8 months. The primary outcome variable was change in best spectacle-corrected visual acuity. RESULTS At postoperative month 12, best spectacle-corrected visual acuity improved in 46 (45%) of 103 eyes and worsened in nine (9%) of 103 eyes by 2 or more Snellen lines. Best spectacle-corrected visual acuity improved by a mean of 1.6 +/- 2.8 Snellen lines (95% confidence interval, 1.1 to 2.1 lines). Every postoperative visit confirmed statistically significant improvement of mean best spectacle-corrected acuity. At month 12, treated eyes had a mean hyperopic shift in refraction of 0.87 diopter and a mean reduction in astigmatism of 0.36 diopter. Treatment appeared most effective in eyes with hereditary corneal dystrophies, Salzmann's nodular degeneration, and corneal scars, and least effective in eyes with calcific band keratopathy. Complications included recurrence of underlying pathology, corneal graft rejection, and bacterial keratitis. CONCLUSIONS Argon fluoride excimer laser phototherapeutic keratectomy is effective, with relatively few complications, for treating vision loss from corneal opacification or irregularity. Efficacy, however, varies widely depending upon individual eyes and underlying diagnoses.

Abstract
A double immunohistochemical labelling procedure in paraffin-embedded renal tissue is reported in which CD3 was targeted as a T cell marker and Ki67 as a marker of cell proliferation. Proliferating and quiescent T cells were unequivocally identified in situ, and their precise location within the kidney was clarified by the use of periodic acid-Schiff counterstaining to outline the basement membranes. Proliferating tubular epithelial cells were also clearly identified. The results showed that T lymphocytes proliferate within the tubular compartment during acute renal allograft rejection. Preliminary evaluation of the method in routine transplant biopsies indicated significant correlations between histologically defined rejection grade and mean intratubular T lymphocytes per tubular cross section and between proliferation of tubular epithelial cells and of intratubular T lymphocytes. The associated tubular epithelial cell proliferation may be a response to local damage.

Abstract
The labelling index is commonly used as a measure of proliferation. However, the use of tritiated thymidine or BrdU labelling of S-phase cells is limited to prospective samples. We have employed an oligonucleotide cocktail complementary to the mRNA species encoding the replication-dependent histones H2B, H3 and H4 for non-isotopic in situ hybridization (NISH), and have compared the resultant proliferation indices in normal skin with those obtained by bromodeoxyuridine (BrdU) incorporation and by Ki67 immunohistochemistry (IHC) using the monoclonal antibody MIB1. In addition, we compared the staining characteristics of histone NISH and Ki67 IHC in a further 25 samples from a variety of inflammatory dermatoses and neoplastic conditions, as well as from normal skin. In normal skin, S-phase (histone NISH and BrdU) and cycling (Ki67) cells were confined to the basal and low suprabasal layers. The labelling indices determined by histone NISH and BrdU incorporation were similar, whereas that of Ki67 IHC was four times greater. In biopsies from hyperproliferative dermatoses and dysplastic or malignant lesions, the number of histone NISH- and Ki67 IHC-positive cells was generally elevated; in accordance with the differential expression of these two markers during the cell cycle, MIB1 consistently gave higher results. The advantage of histone NISH over Ki67 IHC is that it is a marker of the same part of the cell cycle as BrdU incorporation. However, the combined use of both histone NISH and Ki67 IHC to measure two cell cycle parameters, namely S-phase and the number of cycling cells, allows more detailed retrospective study of epidermal proliferation than has been possible previously.

Abstract
This study used self-report of older adolescent/young adult children from a general college population to examine if violent parental conflict tactics predict the use of similarly violent tactics in the same-sex and opposite-sex peer relationships of offspring. Conflict Tactics Scale date from 256 subjects indicate that parental violence within the marital dyad is predictive of violence in both same-sex and opposite-sex peer relationships. Surprisingly high frequencies of violence were reported within parents' marriages and by subjects in their current peer relationships. Implications of these findings are discussed.

Abstract
IV therapy is an anxiety provoking procedure for children who are hospitalized and their families. Adequate preparation can ease children's fears and promote cooperation. A teaching tool was designed to be used with medical play to prepare preschoolers and school-age children for the procedure. An understanding of the use of learning principles to guide design can assist nurses in developing similar teaching tools for children.
