Abstract
In an effort to isolate the effect of theophylline on sleep from the effect of asthma, we examined the impact of oral theophylline on sleep quality in normal, nonasthmatic subjects. Ten healthy, nonsmoking, male subjects ranging in age from 23 to 35 were studied. The subjects were randomly divided into two groups and studied in a double-blinded, crossover designed protocol. Each group underwent two consecutive nights in the sleep laboratory. Group one received four doses of 300 mg of sustained-release theophylline at 12-h intervals prior to the study night. Group two received a placebo. After 14 days, the patients crossed over to the other group, and the procotcol was repeated. The mean serum theophylline level on the morning following the study night was 7.85 +/- SD 2.12 micrograms/ml, with a range of 5.1 to 12.1 microns/ml. The analysis of variance for a crossover design showed no order effect. The analysis for drug effect showed that theophylline administration resulted in a statistically significant adverse effect on arousals per sleep hour (19.3 vs 15.9 for placebo, p = .006) and total sleep time (370.9 min vs 399.45 min for placebo, p = .015). Comparing the sum of ranks data, theophylline was found to have a significant adverse effect on sleep quality (p = .036). We conclude that low doses of oral theophylline result in a significant disturbance in sleep quality in normal nonasthmatic subjects.

Abstract
To our knowledge these are the first three cases of laparoscopic cholecystectomy in heart transplant recipients. In one case the procedure was performed in the early posttransplant period. All three patients had uneventful postoperative outcomes and early hospital discharge. Laparoscopic cholecystectomy may be a safe alternative for elective cholecystectomy in heart transplant recipients.

Abstract
Five replacement vectors (RV) and one insertion vector (IV) were constructed in which ca. 10 kb of genomic Gi2 alpha sequence, flanked on one (IV) or both (RV) sides by a thymidine kinase (TK) marker, were disrupted by a Neo marker inserted into the NcoI site of exon 3. G418RFIAUR clones corresponding to ca. 4 x 10(8) ES cells electroporated with replacement vectors were analyzed and revealed no targeting event. The insertion vector, however, was integrated by a single reciprocal recombination resulting in a duplication of homology (Hit step; G418RFIAUS), which was lost--together with the plasmid and the TK sequences--by intrachromosomal recombination (Run step; G418RFIAUR). Thus, the Hit and Run strategy can be used with a selectable marker disrupting the targeted gene, giving rise to the same targeted product that would have been expected to arise from a double crossover with a replacement vector.

Abstract
Thermal balloon angioplasty has been proposed as a means of reducing acute and delayed reclosure of arteries after percutaneous transluminal balloon angioplasty. A radiofrequency (rf) balloon catheter was used to perform thermal balloon angioplasty on canine arteries in vivo. The histologic appearance of rf-treated sites was compared with that of control sites treated by conventional percutaneous transluminal angioplasty. Acutely, rf-treated sites showed a reduced medial cellularity with preservation of internal elastic lamina except at the transitional zone between thermal injury and normal artery, where localized internal elastic lamina disruption was found. Nonthermal sites showed generalized disruption of internal elastic lamina and normal medial cellularity. Both thermal and nonthermal sites displayed a return of intimal cover commencing at 1 to 2 weeks and completed by 4 weeks. Diffuse myointimal hyperplasia appeared by 2 weeks after injury at breaks in the internal elastic lamina along the nonthermal vessels but was localized to the transitional zone in thermal injury sites. In rf-treated vessels, repopulation of the acellular thermally modified media had commenced by 4 weeks, and by 8 weeks the media was diffusely repopulated by spindle-shaped cells resembling smooth muscle cells lying between and aligned with preserved connective tissue laminae. Overall, the distribution and extent of the proliferative response after rf thermal balloon angioplasty were less than those seen after nonthermal balloon angioplasty. Thermal sites, which underwent reintimalization before medial cells returned, were considerably less prone to the development of myointimal hyperplasia. These results suggest that this modality may have beneficial effects on arterial healing after angioplasty.

Abstract
Usher syndrome (US) is an autosomal recessive disease characterized by congenital hearing impairment and retinitis pigmentosa. It is the most frequent cause of deaf-blindness in adults and accounts for 3 to 6% of deaf children. Here, we report the genetic mapping of a gene for US type I (USH1A), the most severe form of the disease, to the long arm of chromosome 14, by linkage to probe MLJ14 at the D14S13 locus in 10 families of Western France ancestry (Z = 4.13 at theta = 0). Among them, 8 families originated from a small area of the Poitou-Charentes region (Z = 3.78 at theta = 0), suggesting that a founder effect could be involved. However, since not all US type I families were found to be linked to this locus, the present study provides evidence for genetic heterogeneity of this condition (heterogeneity versus homogeneity test HOMOG, P < 0.05; heterogeneity versus no linkage, P < 0.01).

Abstract
Retinitis pigmentosa (RP) represents a group of clinically heterogeneous retinal degenerations in which all modes of inheritance have been described. We have previously found two different clinical profiles in X linked RP as a function of age and mode of onset. The first clinical form has very early onset with severe myopia. The second form starts later with night blindness with mild myopia or none. At least two genes have been identified in X linked forms, namely RP2 (linked to DXS7, DXS255, and DXS14) and RP3 (linked to DXS84 and OTC) on the short arm of the X chromosome. In order to contribute to phenotype-genotype correlations in X linked RP, we tested the hypothesis that the two clinical profiles could be accounted for by the two different gene loci. The present study provides evidence for linkage of the clinical form with early myopia as the onset symptom with the RP2 gene (pairwise linkage to DXS255: Z = 3.13 at theta = 0), while the clinical form with later night blindness as the onset symptom is linked to the RP3 gene (pairwise linkage to OTC: Z = 4.16 at theta = 0).

Abstract
Iron is required for the growth of Saccharomyces cerevisiae. High concentrations of iron, however, are toxic, forcing this yeast to tightly regulate its concentration of intracellular free iron. We demonstrate that S. cerevisiae accumulates iron through the combined action of a plasma membrane ferrireductase and an Fe(II) transporter. This transporter is highly selective for Fe(II). Several other transition metals did not inhibit iron uptake when these metals were present at a concentration 100-fold higher than the Km (0.15 microM) for iron transport. Pt(II) inhibited ferrireductase activity but not the ability of cells to transport iron that was chemically reduced to Fe(II). Incubation of cells in a synthetic iron-limited media resulted in the induction of both ferrireductase and Fe(II) transporter activities. In complex media, Fe(II) transport activity was regulated in response to media iron concentration, while the activity of the ferrireductase was not. When stationary phase cells were inoculated into fresh media, ferrireductase activity increased independent of the iron content of the media; in contrast, transporter activity varied inversely with iron levels. These results demonstrate that the ferrireductase and Fe(II) transporter are separately regulated and that iron accumulation may be limited by changes in either activity.

Abstract
We describe two sisters affected with retinitis pigmentosa of late onset. Night blindness and progressive visual field loss occurred after 50 years of age in both cases. The parents of affected individuals were first cousins and there was no known history of other similar cases in previous generations. Autosomal recessive inheritance is suggested for such senile retinitis pigmentosa.

Abstract
OBJECTIVES Our objective was to compare the relative sizes of circulating lymphocyte subsets in fetuses, newborns, and adults. STUDY DESIGN Two-color flow cytometric analysis of lymphocyte cell surface markers was performed on blood from 64 fetuses, 22 newborns, and 67 normal adults. RESULTS All three groups had similar percentages of CD3+ total T cells, CD4+ helper T cells, CD8+ cytotoxic/suppressor T cells, and CD20+ B cells. Compared with adults, fetuses and newborns had markedly reduced percentages of CD57+ natural killer T cells and consistently increased percentages of CD5+CD20+ B cells. Most fetal and cord T and B lymphocytes expressed the activation marker CD38. CONCLUSIONS Similarities and age-dependent differences exist among fetal, newborn, and adult circulating lymphocyte subsets. Lymphocyte marker analysis may prove useful in the detection of fetal infection and other complications of gestation.

Abstract
Children other than neonates infected with human immunodeficiency virus type 1 (HIV-1) have low rates of progression to acquired immunodeficiency syndrome (AIDS). Through 1989, 5.3% of 95 infected hemophiliacs aged 5 to 13 years developed AIDS, compared with 20.3% of 364 aged greater than or equal to 25 years. We asked whether the HIV-1 impact on peripheral blood mononuclear cell subpopulations differed with age using pairwise comparisons of uninfected and infected male children and adult hemophiliacs. Infected children had lesser reductions of total lymphocytes than adults, but proportionately lower numbers of CD2+, CD4+, CD2+CD26+, and CD4+CD29+ counts. CD4+CD45RA+ cell counts were greater than twofold higher in uninfected and infected children than adults; with infection, the CD4+CD45RA+/CD4+ proportion increased by 1.4-fold in adults, but was unchanged in children. Infected adults had highly significantly increased total CD8+ counts; both age groups had elevated CD8+HLA-DR+ counts. Infected children had significantly higher total B-cell counts than infected adults, with a disproportionately lower number of resting B cells (CD20+CD21+). During 2 years of follow-up, infected children and adults had lymphocyte changes in the same directions and these were proportionately equal. The lower rate of HIV-1 progression in children may be partly associated with differences in lymphocyte populations compared with adults; functional properties of immune cells may be equally or more important.

Abstract
In this review the authors first give an overview of the general strategies of mapping which differ whether the biochemical (molecular) defect of the disease is known or not. The main problems besides mapping are concerned for the first category with the correlation between mutation and phenotype and for the second, with heterogeneity, genetic vs phenotypic. Finally, tables are displayed of eye diseases or diseases with eye involvement (metabolic or not) which have been currently mapped, as well as candidate genes actually or putatively involved in visual transduction.

Abstract
The Coffin-Lowry syndrome (CLS) is an X-linked inherited disease of unknown pathogenesis characterized by severe mental retardation, typical facial and digital anomalies, and progressive skeletal deformations. Our previous linkage analysis, based on four pedigrees with the disease, suggested a localization for the CLS locus in Xp22.1-p22.2, with the most likely position between the marker loci DXS41 and DXS43. We have now extended the study to 16 families by using seven RFLP marker loci spanning the Xp22.1-p22.2 region. Linkage has been established with five markers from this part of the X chromosome: DXS274 (lod score [Z] (theta) = 3.53 at theta = .08), DXS43 (Z(theta) = 3.16 at theta = .08), DXS197 (Z(theta) = 3.03 at theta = .05), DXS41 (Z(theta) = 2.89 at theta = .08), and DXS207 (Z(theta) = 2.73 at theta = .13). A multipoint linkage analysis further placed, with a maximum multipoint Z of 7.30, the mutation-causing CLS within a 7-cM interval defined by the cluster of tightly linked markers (DXS207-DXS43-DXS197) on the distal side and by DXS274 on the proximal side. Thus, these further linkage data confirm and refine the map location for the gene responsible for CLS in Xp22.1-p22.2. As no linkage heterogeneity was detected, this validates the use of the Xp22.1-p22.2 markers for carrier detection and prenatal diagnosis in CLS families.

Abstract
Werdnig-Hoffmann disease is a common autosomal recessive neuromuscular disorder that results in paralysis and death. No treatment to prevent this disease or to alter its unremitting course has been found. Recently, linkage analysis with cloned DNA probes has shown that the mutation causing Werdnig-Hoffmann disease is located on chromosome 5q12-q14. We performed genetic analysis for the prenatal diagnosis of Werdnig-Hoffmann disease in seven at risk families. Two fetuses were diagnosed as being affected and the remainder as unaffected, and this was confirmed after birth. This study shows that prenatal diagnosis of Werdnig-Hoffmann disease has become feasible.

OBJECTIVE To investigate the association between CD5+ B cell expression and IgM rheumatoid factor (IgM-RF) in juvenile rheumatoid arthritis (JRA). METHODS CD5+ B cell levels analyzed by flow cytometry and IgM-RF expression determined by enzyme-linked immunosorbent assay were compared in children with JRA, children with other collagen vascular diseases, and healthy controls. RESULTS Children with polyarticular JRA had expanded populations of CD5+ B cells, and expansion of CD5+ B cells and IgM-RF both correlated with disease activity. CONCLUSION The results indicate that an expanded CD5+ B cell population leads to IgM-RF production in patients with polyarticular JRA, as well as patients with RA.

Abstract
We have found that murine lymphokine activated killer (LAK) cells have veto and natural suppressor activities in vitro, and prevent graft-versus-host disease (GVHD) in vivo. To determine whether human LAK cells mediate veto and natural suppression we measured their ability to inhibit generation of allospecific cytotoxic T cells (CTL) in mixed lymphocyte culture (MLC). When added to MLCs at low concentrations LAK cells caused veto-type inhibition: stimulator-type LAK cells inhibited generation of CTL but responder or third-party LAK cells did not. At higher concentrations LAK cells caused nonspecific inhibition: all three LAK cell types inhibited generation of CTL. LAK cell veto and natural suppressor activities were largely eliminated by irradiation with 30 Gy and by depletion of CD56+ cells, but increased after depletion of CD3+ cells. LAK cell veto activity is not likely an artifact of cold-target inhibition by the LAK cells themselves or by proliferation of T cells contaminating LAK cell preparations: (1) veto only occurred when LAK cells were added to MLC on days 0 through 2, but not when added on day 5; (2) addition of saturating numbers of labeled targets to fixed numbers of allo-CTL effectors failed to overcome the inhibitory effects of adding stimulator-type LAK cells at the onset of MLC; and (3) CD3-depleted LAK cells showed greater veto activity than threefold greater numbers of control LAK cells. In light of our previous findings in mice, the current results imply that adoptive immunotherapy with LAK cells may be useful in preventing GVHD in human bone marrow transplant recipients.

Abstract
We used a unique animal model, the hypotransferrinemic (Htx) mouse, to examine the role of transferrin (Tf) in gastrointestinal iron uptake. Despite the absence of Tf, Htx animals hyperabsorb iron. Transfusion of red blood cells sufficient to normalize the hematocrit and reticulocyte count resulted in a return of iron absorption to normal values. These studies indicate that Tf does not play an obligate role in iron absorption, either as a carrier or as a humoral signal regulating absorption. Transfer of plasma or whole blood from Htx mice or from other animal models of iron hyperabsorption to normal mice did not cause an increase in iron absorption in recipient animals. Using the plasma or blood transfer approach, we have been unable to detect a humoral regulator of gastrointestinal iron absorption.
