Abstract
The structures of two lipids from the radiation-resistant bacterium Deinococcus radiodurans are reported here: 1,2-diacyl-3-alpha-glucopyranosyl-glycerol and 3-O-[6'-O-(1",2"-diacyl- 3"-phosphoglycerol)-alpha-glucopyranosyl]-1,2-diacylglycerol. These lipids are strikingly different from previously characterized polar lipids from this organism, in that they are not unique to the genus Deinococcus and indeed have counterparts in both gram-negative and gram-positive bacteria. Moreover, as examples of glucose-containing lipids, they further illustrate the diversity of carbohydrate-containing lipids in D. radiodurans, from which lipids containing galactose and N-acetylglucosamine have already been structurally characterized.

Abstract
Because of improved life expectancy for people with HIV infection, today's clinician needs to understand and manage chronic symptoms that limit function and quality of life. The authors describe two collaborative HIV symptom-management studies conducted by the Division of Intramural Research of the National Institute of Nursing Research. Studies such as these are necessary to provide nurses and other healthcare personnel with the knowledge essential for appropriate, comprehensive, and quality patient care.

Abstract
The macronuclear genome of hypotrichous ciliates consists of DNA molecules of gene-sized length. A macronuclear DNA molecule contains a single coding region. We have analyzed the many hypotrich macronuclear DNA sequences sequenced by us and others. No highly conserved promoter sequences nor replication initiation sequences have been identified in the 5' nor in the 3' non-translated regions, suggesting that promoter function in hypotrichs may differ from other eukaryotes. The macronuclear genes are intron-poor; approximately 19% of the genes sequenced to date have one to three introns. Not all macronuclear DNA molecules may be transcribed; some macronuclear molecules may not have any coding function. Codon bias in hypotrichs is different in many respects from other ciliates and from other eukaryotes.

Abstract
Epidemiological data strongly implicate a role for the host humoral immune response in both protection against and exacerbation of dengue virus-caused disease. In an effort to characterize elements of the normal human immune response against dengue virus we have addressed the issue of antibody-mediated neutralization of dengue virus. We show here the ability of both mouse monoclonal antibody 3H5 and human anti-dengue neutralizing sera to block binding of dengue-2 virus to monkey kidney (Vero) cells. Since Vero cells possess virus receptors but not Fc receptors we conclude that the major effect of host neutralizing antibodies is to block virus attachment to Vero cell dengue virus receptors. Analysis of 61 patient antisera yielded good correlation (Pearson's coefficient = 0.90; P < 0.001) between neutralizing activity and ability to block virus-cell attachment suggesting that antibody-mediated neutralization of dengue virus occurs primarily extracellularly and less by a postattachment mechanism as has been described for certain other viruses.

Abstract
There is currently no animal model which reliably predicts the immunogenicity of Haemophilus influenzae type b (Hib) polysaccharide-protein conjugate vaccines in human infants. We evaluated various Hib vaccines in guinea pigs using techniques similar to the United States potency test for adsorbed diphtheria and tetanus toxoids with a view to developing a method for evaluating the potency of a combined adsorbed tetanus, diphtheria, pertussis and Hib conjugate vaccine. Groups of 6-8 guinea pigs received 1.5 single human doses of vaccine at 0 and at 6 or 8 weeks and were bled at 6 weeks and 2 weeks after the booster injection. Total antibodies to polyribosylribitolphosphate (PRP), the Hib capsular polysaccharide, were measured in individual animals and in serum pools by radioimmunoassay. The relative antibody responses of guinea pigs to Hib conjugate vaccines qualitatively resembled those of human infants. Unconjugated polysaccharide was not immunogenic; PRP-D produced a low antibody response, HbOC, PRP-T (Merieux) and Hib-T (MPMBL) produced a low response to the first dose and a strong anamnestic response to the booster (geometric mean anti PRP > 1 micrograms ml-1). PRP-OMP uniquely produced a strong response after the first dose which was further boosted by the second dose. Experimental Hib-T vaccine lots with low levels of conjugation were poorly immunogenic in guinea pigs. Combinations of DTP and Hib-T vaccines showed equivalent or greater immunogenicity than Hib-T alone. We propose that the guinea pig model may be useful to verify the immunogenicity of PRP conjugate vaccines and for pre-clinical evaluations of DTP-Hib combination vaccines containing PRP conjugates.

Abstract
Ninety-three symptomatic HIV antibody positive patients were randomized to receive zidovudine (ZDV) 600 mg/day and acyclovir (ACV) 4,800 mg orally per day versus ZDV 600 mg/day plus placebo. Urine was obtained at 3-month intervals and cultured for cytomegalovirus (CMV) in diploid fibroblast cells. The percent of urine specimens positive for CMV was 7.1% in the ZDV group and 5.8% in the ZDV plus ACV group (p = 0.55); 27% of patients had at least one urine culture positive for CMV while taking ZDV, versus 20% of patients taking the combination of ZDV plus ACV (p = 0.52). We conclude that ACV at a dosage of 4,800 mg/day does not suppress CMV excretion in urine of symptomatic HIV antibody positive patients taking concurrent ZDV. Use of ACV did not appear to induce resistance of CMV to ganciclovir since the ID50 of isolates from the two treatment groups did not differ.

Abstract
Relationships between Beck's constructs of sociotropy/autonomy and Blatt's constructs of dependency/self-criticism and the Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev.; American Psychiatric Association, 1987) Axis II personality disorders were examined. Two measures of personality styles and a structured diagnostic interview for personality disorders were administered to 138 outpatients. Significant relationships were found between both sets of constructs and a number of personality disorders using both categorical and dimensional measures of Axis II psychopathology. These relationships were consistent with previous theory, supporting recent conceptualizations extending the range of psychopathology associated with these personality styles from depression to the personality disorders. However, the autonomy/self-criticism dimension was correlated with a broader range of personality disorder traits and diagnoses than anticipated.

Abstract
Little is known about the mechanisms of antibody-mediated neutralization of respiratory syncytial virus (RSV) which causes recurrent infections in human despite the virtually universal presence of neutralizing serum antibodies. Human serum neutralization titers showed strong correlation with post-cell-attachment neutralizing titers for both RSV-convalescent sera and control sera but showed less strong correlation with cell-attachment blocking titers. Neutralization was effective for the first 60 min of infection, indicating that immune serum-mediated neutralization of RSV infection largely involves inhibition of early events following cell attachment.

Abstract
Two overlapping cDNA clones encoding pigeon liver carnitine acetyltransferase (EC 2.3.1.7) (CAT) were isolated from a pigeon liver lambda gt11 cDNA library by gene amplification using oligonucleotide primers based on the N-terminal amino acid sequence of the enzyme. The two clones, which represent the 5' and 3' ends of the gene, were spliced together to form a single cDNA construct containing the entire coding sequence for CAT, with an in-frame TGA stop codon 42 bases before the first ATG start site and a 3'-untranslated segment of 1057 bases. The largest open reading frame of 1942 nucleotides predicted a polypeptide of 627 amino acids and a molecular mass of 71.1 kDa. The N-terminus and four internal peptides from the amino acid sequence of pigeon breast muscle CAT were identified in the predicted sequence of the liver cDNA clone. The identity of the CAT cDNA was confirmed by heterologous expression of active recombinant CAT (rCAT) in insect cells using the baculovirus expression system. Western blots of rCAT from infected insect cell lysates and immunodetection with a rabbit anti-CAT polyclonal serum showed an immunoreactive protein band similar in size to native CAT from pigeon breast muscle. Like the native enzyme, rCAT was capable of acylating carnitine with a preference for small-chain acyl-CoAs of carbon chain lengths C2-C4.

Abstract
Fibrous dysplasia of the anterior cranial base involves the bony orbit and optic canal. Although fibrous dysplasia is benign, it may produce a mass effect along the course of the optic nerve, inducing visual disturbances. Optic canal decompression in patients without clinical signs of optic neuropathy is controversial. We describe five patients with extensive fibrous dysplasia of the anterior cranial base involving the orbit and optic canal. These patients underwent transcranial optic canal decompression before signs of severe visual loss during correction of dystopias and craniofacial deformity induced by fibrous dysplasia. Cranial orbital reconstruction was performed by means of split rib and cranial bone grafts. Postoperative follow-up did not reveal disturbances in visual function, extraocular motility, or evidence of cerebrospinal fluid fistulas. This suggests that early, radical resection of orbital fibrous dysplasia with optic canal decompression may be effective in preventing visual loss with minimal risk of other neurological sequelae. Subsequent orbital reconstruction involving split-thickness rib and cranial bone grafting yields satisfactory cosmetic results.

Abstract
The local tissue concentration of released titanium from Ti-6Al-4V posterior cervical spine plates in canines was determined using inductively coupled plasma atomic emission spectroscopy. The plates were also evaluated for percentage of surface area damage. The highest titanium levels (> 100 ppm dry weight) and most severe surface damage were associated with screw-plate interfaces. A model to explain the metal release mechanisms was proposed, consisting of a combination of fretting wear, diffusion through the passive oxide layer, and dissolution of this layer.

Abstract
The mature pertactin protein (P.69) of Bordetella pertussis can be isolated from the bacterial cell surface as a polypeptide with an apparent molecular mass of 69,000 Da as determined by sodium dodecyl sulphate gel electrophoresis. However the open reading frame of prn, the pertactin gene, encodes a polypeptide with a predicted molecular mass of 93,478 Da, referred to as P.93. Expression of the prn gene in Escherichia coli leads to the synthesis of the full-length P.93 polypeptide, which is rapidly processed to the mature P.69 protein located at the cell surface. The P.93 precursor polypeptide is processed at both termini. A 34 amino acid long signal sequence is removed from the amino-terminus and a polypeptide sequence of about 30,000 Da (P.30) is cleaved from the carboxy-terminus. Deletion of the 3' region of prn, encoding P.30, results in the expression of an intracellular form of P.69. Antiserum which recognizes P.30 was raised using synthetic peptides based on the primary amino acid sequence of the region. This anti-P.30 serum was used in a Western blot analysis of fractionated cells of B. pertussis and E. coli harbouring the intact prn gene. The P.30 polypeptide was readily detected in outer membrane fractions prepared from both of these bacterial species, although it could not be shown to be exposed at the cell surface.

Abstract
1. The effects of a range of adenosine receptor-selective ligands on body temperature were investigated following intracerebroventricular (i.c.v.) and intraperitoneal (i.p.) injection in conscious mice. The compounds tested were the non-selective adenosine receptor agonist 5'-N-ethyl-carboxamidoadenosine (NECA), the adenosine A1 receptor-selective agonists cyclopentyl-adenosine (CPA), N6-(9R-phenyl-isopropyl)-adenosine (R-PIA) and N-(1S,trans)-[2-hydroxyclopentyl]-adenosine (GR79236), the A2a receptor selective agonist 2-[p-(2-carboxyethyl)phenethylamino]-5'-N-ethylcarboxyamidoaden osine (CGS-21680), the A2b receptor agonist N-[(2-methylphenyl)methyl[adenosine (metrifudil) and the A3 receptor agonist N6-(4-aminophenylethyl)adenosine (APNEA). 2. NECA (0.01-1 microgram, i.c.v.), all of the A1-selective agonists (0.01-1 microgram, i.c.v.) and APNEA (0.1-3 micrograms i.c.v.) produced profound and dose-related hypothermia and sedation. However, CGS-21680 (0.1-10 micrograms i.c.v.) and metrifudil (0.01-1 microgram i.c.v.), produced only mild hypothermia at the highest doses tested. 3. The hypothermic response to the A1 receptor-selective agonists, GR79236 and R-PIA was dose-dependently antagonized by peripheral administration of either the non-selective adenosine receptor antagonist, 8-phenyltheophylline (8-PT, approximately 40 and 30 fold rightward shifts of the dose-response curves respectively at 10 mg kg-1, i.p.), or the adenosine A1 receptor-selective antagonist, 8-cyclopentyl-1,3-dipropylxanthine (DPCPX, approximately 20 fold shift of the GR79236 dose-response curve at 1 mg kg-1, i.p.). The hypothermic response to APNEA was similarly dose-dependently antagonized by the A1 receptor-selective antagonist, DPCPX (5 fold shift at 0.1 mg kg-1, i.p.). 4.8(p-Sulphophenyl)theophylline (8-SPT, 10 and 30 mg kg-1, i.p.), a non-selective adenosine receptorantagonist that penetrates the blood brain barrier poorly, produced only modest antagonism (approximately 2 fold shift at 30 mg kg-1, i.p.) of the hypothermic response to GR79236.5. These data suggest that hypothermia induced by adenosine analogues in the conscious mouse is mediated via adenosine A1 receptors, which are probably located in the CNS.

Abstract
Respiratory syncytial virus (RSV) convalescent-phase sera and control sera from both infants ( < 6 months) and older individuals (1.5 to 90 years) were assayed for RSV-specific antibodies by neutralization, in vitro enhancing activity, and immunoprecipitation. Enhancement of RSV infection in U937 cells was demonstrated with convalescent-phase sera and was shown to be dependent on Fc receptors by blocking with human immunoglobulin G (P < 0.01). Convalescent-phase sera from infants enhanced infection at concentrations closer to physiological ones (10(-1) to 10(-3) dilutions of serum), while convalescent-phase sera from older individuals enhanced infection only at much lower concentrations (10(-3) to 10(-6) dilutions of serum; P < 0.01). To our knowledge, this is the first report of RSV-enhancing antibody activity in the sera of infants. The observed enhancing activity and the low neutralizing antibody levels are confined mostly to convalescent-phase sera from infants aged 0 to 6 months, suggesting that these factors may contribute to the increased severity of RSV disease frequently encountered in young infants.

Abstract
We compared the composition and opsonic activities for two common microbial pathogens (Staphylococcus aureus and Streptococcus pyogenes) of various imported intravenous (IV) (Sandoglobulin, Octagam and Gammagard) and intramuscular (IM) (Beriglobin and Globuman Berna) immunoglobulin (Ig) preparations with those of the corresponding locally manufactured products, Polygam (IV) and Intragam (IM). When tested at equivalent concentrations (1 g/100 ml) the total IgG and IgG subclass concentrations of the various IV and IM preparations were similar. All the test preparations (IV and IM) possessed similar opsonic activity for S. aureus and S. pyogenes. These findings demonstrate that, in respect of IgG content and protective biological activity, Intragam and Polygam, the locally manufactured IM and IV Ig preparations, respectively, compared extremely favourably with the corresponding imported products.

Abstract
BACKGROUND AND PURPOSE Although US blacks are known to have an excess stroke mortality compared with US whites, little is known about the stroke burden of the Hispanic white population. This report will provide estimates of the relative burden of stroke mortality in the US black and Hispanic population relative to the white population and examine the consistency of this relation across age. METHODS Data were from participants aged > 45 years from the National Longitudinal Mortality Study. There were 1844 stroke deaths among 239,734 non-Hispanic whites, 46 deaths among 12,527 Hispanic whites, and 234 deaths among 23,468 black participants. Standard statistical methods were used to examine the ethnic differences in stroke mortality. RESULTS The hazard ratios for black men and women (relative to non-Hispanic whites) were nearly identical, at > 4.0 at age 45 but marginally < 1.0 by age 85. For both Hispanic men and women, the hazard ratios (relative to non-Hispanic whites) were approximately 1.0 at age 45 but were marginally significantly < 1.0 at older ages. The ethnic differences in stroke death rates reveal differences in age distributions of age at fatal stroke between these groups. Approximately 6% of fatal strokes for non-Hispanic whites occurred before age 60, whereas > 15% occurred in both Hispanic whites and blacks. CONCLUSIONS These results suggest that (1) for Hispanics, stroke risk is similar to that for non-Hispanic whites at young ages but is marginally lower at older ages, (2) the excess stroke mortality in blacks mainly occurs at younger ages (between 45 and 55 years), and (3) the relation between stroke risk for blacks and Hispanics relative to whites is similar by sex. The impact of age on relative stroke mortality would argue against simple age adjustment for describing ethnic differences in stroke mortality. Finally, proportionally, more strokes occur at older ages in non-Hispanic whites than in either US blacks or Hispanic whites.

Abstract
Twenty HIV-infected outpatients participating in clinical drug trials of the National Institute of Allergy and Infectious Diseases (NIAID) and enrolled in the collaborative National Institute of Nursing Research (NINR) nutrition study underwent indirect calorimetry measurements. Energy requirements for these subjects also were calculated using the Harris Benedict Equation (HBE). In all 20 subjects, the calculated energy requirements underestimated actual resting expenditure as determined by indirect calorimetry.
