In vitro growth and differentiation of rabbit bulbar, fornix, and palpebral conjunctival epithelia. Implications on conjunctival epithelial transdifferentiation and stem cells. (1993)

This observation, coupled with previous findings that the "transdifferentiation" of conjunctival epithelial cells to corneal epithelium appears to be both incomplete and reversible, provides strong evidence that (1) the limbal-corneal epithelial cells form a lineage distinct from the conjunctival lineage and (2) conjunctival transdifferentiation actually represents a process of environmental modulation. In addition, of the three types of conjunctival epithelial cells, fornix cells were found to have a much greater proliferative potential than bulbar and palpebral cells. This observation, coupled with recent finding that fornix is enriched in slow-cycling (label-retaining) cells, raises the possibility that conjunctival epithelial stem cells may preferentially reside in the fornix.
The structural organization of type IV collagen. Identification of three NC1 populations in the glomerular basement membrane. (1992)

Type IV collagen, which has long been assumed to contain two alpha 1(IV) and one alpha 2(IV) chains, also contains alpha 3(IV), alpha 4(IV), and alpha 5(IV) chains. Stoichiometry of collagenous alpha(IV) chains differs among tissues, suggesting the existence of subclasses of type IV collagen, each with a unique chain composition. This study seeks to define, by characterization of subunit compositions of NC1 domain populations, the structural organization of type IV collagen from bovine glomerular basement membrane. NC1 hexamers from type IV collagen were separated on two affinity chromatography columns, one containing monoclonal antibodies to the alpha 3 chain, and another, to the alpha 1 chain. SDS-polyacrylamide gel electrophoresis, immunoblotting, reversed phase high-performance liquid chromatography, and enzyme-linked immunosorbent assay identified three NC1 hexamer populations: 1) a hexamer composed of (alpha 1)2 and (alpha 2)2 homodimers; 2) a hexamer composed of (alpha 3)2 and (alpha 4)2 homodimers; 3) a hexamer containing all four alpha chains connected in heterodimers, alpha 1-alpha 3 and alpha 2-alpha 4. Results suggest that there are two distinct type IV collagen molecules, one composed of alpha 1(IV) and alpha 2(IV) chains and another composed of alpha 3(IV) and alpha 4(IV) chains. Furthermore, polymerization occurs between molecules with the same chain composition and between molecules with different chain composition. Moreover, crosslinking between different alpha chains is restricted, thus limiting the number of possible macromolecular structures.
Comparative evaluation of enoxacin, ofloxacin, ampicillin, and chloramphenicol for treatment of experimental Haemophilus influenzae pneumonia (1987)

A murine model of bacteremic Haemophilus influenzae type b pneumonia was used to evaluate the therapeutic efficacies of the quinolone antimicrobial agents enoxacin and ofloxacin compared with those of ampicillin and chloramphenicol. Ampicillin-susceptible (AS) and ampicillin-resistant (AR) challenge strains were employed. Treatment with enoxacin or ofloxacin produced intrapulmonary killing of H. influenzae that was superior to that achieved with ampicillin (P less than 0.01 to P less than 0.001 for both AS and AR strains). Ofloxacin and enoxacin also provided killing greater than that with chloramphenicol for the AS strain (P less than 0.01 to P less than 0.001). For the AR strain, ofloxacin provided killing greater than that obtained with chloramphenicol (P less than 0.001). Survival from AS strain pneumonia was 60% in enoxacin-treated and 78% in ofloxacin-treated animals compared with 41% for chloramphenicol-treated and 23% for ampicillin-treated groups. We conclude that enoxacin and ofloxacin may be effective antimicrobial agents in treating either AS or AR strains causing H. influenzae pneumonia.
Measurement of permittivity and dissipation factor without attached electrodes (1960)

A method for measuring the permittivities of thin films, without the necessity of attaching electrodes or determining the dimensions, has been described. The results presented indicate that a precision of 0.1 percent is possible. An accuracy of better than 1 percent is probable. Excellent results were obtained even though some of the specimens occupied 10 percent or less of the electrode spacing. Excellent results were also obtained for dissipation factor. Insufficient data are available to permit an estimate of the precision and accuracy obtainable.
Structures of the triglycerides of cows' milk, fortified milks (including. infant formulae), and human milk (1982)

The positional distributions of fatty acids in triglycerides from cows' milk, cows' milk enriched in linoleic acid by dietary means, and two commercial infant formulae fortified with vegetable fats have been determined for comparison with human milk. The results are discussed in terms of the digestibility of the fats and of the requirements of the human infant for linoleic acid .
Altered Clearance of Gadolinium Diethylenetriaminepentaacetic Acid Aerosol from Bleomycin-injured Dog Lungs: Initial Observations (2003)

To characterize altered alveolar transfer to solute in bleomycin (BLM)-injured lungs, eight dogs underwent a gadolinium diethylenetriaminepentaacetic acid aerosol (Gd-AS) magnetic resonance imaging study before and on Days 7 and 40 after tracheal instillation of BLM (0.75 mg) in the left lungs. Consecutive fast-gradient echo magnetic resonance imaging was acquired during and after spontaneous inhalation of 200-mM Gd-AS. The slope (Kep) and clearance half-time (T1/2) of logarithmic regression lines for clearance curves were estimated. Histology on Day 40 was compared with that on Day 7 in another three dogs. On Days 7 and 40, Gd-AS deposition was heterogeneously reduced in the affected lungs. On Day 7 with multifocal intraalveolar exudative changes, Kep in affected areas was significantly increased compared with baseline (2.5 x 10(-3) minutes(-1) +/- 0.3 versus 1.7 x 10(-3) minutes(-1) +/- 0.2, p < 0.0001), with significant decrease in T1/2 (121.6 +/- 19.7 minutes vs. 170.4 +/- 15.8 minutes, p < 0.001). However, on Day 40 with multifocal interstitial fibrosis, Kep and T1/2 were recovered toward baseline. BLM-injured lungs can be characterized by accelerated Gd-AS clearance during the acute exudative phase and their recovery during the chronic fibrotic phase. This technique is acceptable for monitoring alveolar transfer changes in BLM-injured lungs.
Cigarette smoking and hypertension. Factors independently associated with blood hyperviscosity and arterial rigidity. (1987)

The effects of cigarette smoking and hypertension on hemorheological variables (blood viscosity over a wide range of shear rates, plasma viscosity, microhematocrit, and plasma protein concentration) and on arterial stiffness (pulse wave velocity) were investigated in 33 normotensive men and 81 mild to moderately hypertensive men. Of these, 22 normotensive and 24 hypertensive subjects were cigarette smokers. Cigarette smoking and hypertension were independently associated with higher blood viscosity at all studied shear rates (from 0.2 to 241 sec-1) as well as with higher plasma viscosity, hematocrit, and pulse wave velocity. At constant hematocrit levels, hypertension remained associated with a higher blood viscosity, while the association with cigarette smoking disappeared. Normotensive smokers had the same increase of blood and plasma viscosity and pulse wave velocity as hypertensive nonsmokers. No interactive effects of hypertension or cigarette smoking on blood or arterial variables were observed, suggesting that the effect of these two factors on blood and vascular rheology are cumulative. Smoking and hypertension may change the flow properties of the blood and the behavior of the arterial wall and this may explain the arterial damage observed in cigarette smokers and hypertensive patients.

Decoding individual identity from brain activity elicited in imagining common experiences (2020)

Everyone experiences common events differently. This leads to personal memories that presumably provide neural signatures of individual identity when events are reimagined. We present initial evidence that these signatures can be read from brain activity. To do this, we progress beyond previous work that has deployed generic group-level computational semantic models to distinguish between neural representations of different events, but not revealed interpersonal differences in event representations. We scanned 26 participants' brain activity using functional Magnetic Resonance Imaging as they vividly imagined themselves personally experiencing 20 common scenarios (e.g., dancing, shopping, wedding). Rather than adopting a one-size-fits-all approach to generically model scenarios, we constructed personal models from participants' verbal descriptions and self-ratings of sensory/motor/cognitive/spatiotemporal and emotional characteristics of the imagined experiences. We demonstrate that participants' neural representations are better predicted by their own models than other peoples'. This showcases how neuroimaging and personalized models can quantify individual-differences in imagined experiences.
A double-focus lens interferometer for scanning force microscopy (1995)

We present a laser interferometer for displacement measurement requiring high precision. Consisting of a small number of optical parts, the instrument is simple, compact, and not affected by environmental conditions. Further, with a birefringent double-focus lens, the two interfering beams share a common path and the interference signal is immune to fluctuations of the optical path length. Peak-to-peak noise in a dc to 1 kHz bandwidth is less than 0.02 Å. We applied this interferometer to scanning force microscopy and tested the performance.
Minimizing Radioactivity and Other Features of Elemental and Isotopic Tailoring of Materials for Fusion Reactors (1978)

The levels of induced radioactivity in fusion devices can be controlled by appropriate selection of elements in a structural alloy and, in principle, by the selection of specific isotopes of a particular element. Three general rules are developed by which long-term induced radioactivity can be minimized. These rules are then applied to two specific alloy systems—stainless steels and the molybdenum alloy, TZM. A particular steel, Tenelon, containing neither nickel nor molybdenum, is especially attractive. It is found that the principles of both elemental substitution and isotopic tailoring can reduce the long-term radioactivity levels by orders of magnitude compared to normal Type 316 stainless steel.A comparison of long-term activity levels in such systems as the liquid-metal fast breeder reactor, fusion with standard structural alloys, and fusion with steel alloys designed for low activity quantitatively shows the potential advantage of fusion in this area. The influence of isotopic tailoring on gas production rates is also discussed. The calculations on radioactivity indicate that with proper attention to the choice of materials and isotopes, long-term radioactivity in fusion devices can be made so low as to either eliminate concern over long-term storage or allow recycling within a few human generations.
Preparation and transformations of allenic ketones and 3(2<i>H</i>)-furanones (1984)

Swern oxidation of allenic alcohols 7 and 10 gives the corresponding ketones 3 and 12. Reaction of 3 with ruthenium tetroxide yields the stable acyl ketene 17 and the acyloxy α-diketone 20 as well as pivalil (4). Formation of 20 by way of the 3(2H)-furanone 22 is suggested, since oxidation of 3 and 12 with osmium tetroxide followed by dehydration provides the corresponding furanones 22 and 26 in good yield. Epoxidation of 3 furnishes some 20 as well as 27 and 29, the first stable keto allene oxide and bisepoxide, respectively. On thermolysis 27 rearranges to furanone 22. The double bond of 22 is cleaved by peracid to form 20; similar treatment of 31a, b leads to cleavage of the double bond accompanied by Baeyer–Villiger oxidation, with formation of the carboxylic acids corresponding to methyl esters 33a, b as the major products.
Re-Ir coating effect of molding core (WC) surface for aspheric glass lens (2007)

Recently, with increasing lightness and miniaturization of high resolution camera phones, the demand for aspheric glass lens has increased because plastic and spherical lenses are unable to satisfy the required performance. An aspheric glass lens is fabricated by high temperature and pressure molding using a tungsten carbide molding core, so precision grinding and coating technology for the molding core surface is required. In this paper, the optimal grinding condition of the tungsten carbide molding core was found after applying DOE to the development of the aspheric glass lens for the 3 mega pixel and 2.5 magnifications optical zoom for camera phone module. Also, the ultra precision grinding process was investigated under this condition by experiment. Rhenium-Iridium(Re-Ir) coating was applied on the ground surface of the tungsten carbide molding core. The influence of Re-Ir coating on the form accuracy and surface roughness was compared and evaluated. The form accuracy and surface roughness of the molding core were improved by application of Re-Ir coating on the surface of the tungsten carbide molding core. Aspheric lenses were also molded with the non-coated molding core and the Re-Ir coated molding core. Form accuracy(PV) and surface roughness(Ra) were measured. The form accuracy of the aspheric glass lens improved about 0.01 μm (aspheric surface) and the surface roughness by about 0.5 nm (aspheric surface).
New Serum Markers for the Detection of Severe Acute Pancreatitis in Humans (2001)

Acute pancreatitis is an inflammatory process which occurs in a normal organ and which is diagnosed mainly by acute abdominal pain associated with a concomitant rise of serum amylase and lipase concentrations (1, 2). Gallstone migration into the common bile duct and alcohol abuse account for most of the etiologies of the disease. Usually the injury is mild, but 20% of the patients have a severe injury and, among them, 15 to 25% will die. Because it is important to predict the severity of the illness as early as possible in order to optimize the therapy and to prevent organ dysfunction and local complications, several scores of severity have been proposed. Criteria of severity, such as Ranson (3‐5), Glasgow (6), and Acute Physiology and Chronic Health Evaluation (APACHE) (7) scores have been used for a long time. These scores assess the multiple organ dysfunction induced by the disease and consequently, the greater the number of organs injured, the greater the score. New serum markers have recently emerged and their potential for providing additional information on the severity of the disease is currently being evaluated. However, to become useful such markers must be assessed in a large consecutive series of patients, including a significant proportion of severe cases, and the timing of the assessment must be related to the onset of the disease. Moreover, the usefulness of the new marker must be compared with established ones; the results must be reproducible; and the detection of the new marker must be easy to detect in clinical chemistry laboratories. Interestingly, when seeking medical attention (usually 12 to 24 h after the onset of pain) most patients do not exhibit multiple organ dysfunction, which is likely to emerge by the second or third day and, at admission, numerous mediators can be detected in serum. If the concentration of these biologic factors is correlated to the severity of the disease, and if they are detected before the occurrence of multiple organ dysfunction, it is then conceivable that the therapeutic antagonism of these mediators might prevent or attenuate the severity of the multiple organ dysfunction, and consequently the outcome of the disease. These new factors might be important for the rapid scoring of the disease severity in the acute phase and some of them might be used as potential therapeutic targets.
REMOTE HANDWRITTEN SIGNATURE AUTHENTICATION (2005)

This paper presents a secure real-time remote user authentication system based on dynamic handwritten signature verification. The system allows users to establish their identities to other parties in real-time via a trusted verification server. The system can be used to gain remote access to restricted content on a server or to verify a signature on a legal document. State of the art dynamic verification techniques are combined with proven cryptographic methods to develop a secure model for remote handwritten signature verification.
The Rac2 Guanosine Triphosphatase Regulates B Lymphocyte Antigen Receptor Responses and Chemotaxis and Is Required for Establishment of B-1a and Marginal Zone B Lymphocytes (2002)

We have defined roles for the hemopoietic-specific Rho guanosine triphosphatase, Rac2, in B lymphocyte development and function through examination of rac2(-/-) mice. Rac2-deficient mice displayed peripheral blood B lymphocytosis and marked reductions in peritoneal cavity B-1a lymphocytes, marginal zone B lymphocytes, and IgM-secreting plasma cells as well as reduced concentrations of serum IgM and IgA. The rac2(-/-) B lymphocytes exhibited reduced calcium flux following coligation of B cell AgR and CD19 and reduced chemotaxis in chemokine gradients. T cell-independent responses to DNP-dextran were of reduced magnitude, but normal kinetics, in rac2(-/-) mice, while T-dependent responses to nitrophenyl-keyhole limpet hemocyanin were subtly abnormal. Rac2 is therefore an essential element in regulating B lymphocyte functions and maintaining B lymphocyte populations in vivo.
Antigenic Fingerprinting following Primary RSV Infection in Young Children Identifies Novel Antigenic Sites and Reveals Unlinked Evolution of Human Antibody Repertoires to Fusion and Attachment Glycoproteins (2016)

Respiratory Syncytial Virus (RSV) is the major cause of pneumonia among infants. Here we elucidated the antibody repertoire following primary RSV infection and traced its evolution through adolescence and adulthood. Whole genome-fragment phage display libraries (GFPDL) expressing linear and conformational epitopes in the RSV fusion protein (F) and attachment protein (G) were used for unbiased epitope profiling of infant sera prior to and following RSV infection. F-GFPDL analyses demonstrated modest changes in the anti-F epitope repertoires post-RSV infection, while G-GFPDL analyses revealed 100-fold increase in number of bound phages. The G-reactive epitopes spanned the N- and C-terminus of the G ectodomain, along with increased reactivity to the central conserved domain (CCD). Panels of F and G antigenic sites were synthesized to evaluate sera from young children (<2 yr), adolescents (14-18 yr) and adults (30-45 yr) in SPR real-time kinetics assays. A steady increase in RSV-F epitope repertoires from young children to adults was observed using peptides and F proteins. Importantly, several novel epitopes were identified in pre-fusion F and an immunodominant epitope in the F-p27. In all age groups, antibody binding to pre-fusion F was 2-3 folds higher than to post-fusion form. For RSV-G, antibody responses were high following early RSV infection in children, but declined significantly in adults, using either G proteins or peptides. This study identified unlinked evolution of anti-F and anti G responses and supportive evidence for immune pressure driven evolution of RSV-G. These findings could help development of effective countermeasures including vaccines.
Defective collagen crosslinking in bone, but not in ligament or cartilage, in Bruck syndrome: Indications for a bone-specific telopeptide lysyl hydroxylase on chromosome 17 (1999)

Bruck syndrome is characterized by the presence of osteoporosis, joint contractures, fragile bones, and short stature. We report that lysine residues within the telopeptides of collagen type I in bone are underhydroxylated, leading to aberrant crosslinking, but that the lysine residues in the triple helix are normally modified. In contrast to bone, cartilage and ligament show unaltered telopeptide hydroxylation as evidenced by normal patterns of crosslinking. The results provide compelling evidence that collagen crosslinking is regulated primarily by tissue-specific enzymes that hydroxylate only telopeptide lysine residues and not those destined for the helical portion of the molecule. This new family of enzymes appears to provide the primary regulation for controlling the different pathways of collagen crosslinking and explains why crosslink patterns are tissue specific and not related to a genetic collagen type. A genome screen identified only a single region on chromosome 17p12 where all affected sibs shared a cluster of haplotypes identical by descent; this might be the BS (Bruck syndrome) locus and consequently the region where bone telopeptidyl lysyl hydroxylase is located. Further knowledge of this enzyme has important implications for conditions where aberrant expression of telopeptide lysyl hydroxylase occurs, such as fibrosis and scar formation.
A scanning electron microscopic study of the nephron (1974)

Abstract Scanning electron microscopy was used to study the ultrastructural morphology of the nephron. Material for observation was taken from rat kidneys which were fixed by vascular perfusion. Different techniques for splitting open the kidney, combined with stereoscopic viewing, provided many instructive views of nephron morphology. In addition, scanning electron microscopy revealed a number of new features including (1) the complex organization and structure of kidney podocytes; (2) the distribution of endothelial pores and the presence of endothelial microprojections and branching endothelial thickenings; and (3) the presence, distribution and morphology of microprojections and cilia on the luminal surfaces of Bowman's capsule and the uriniferous tubules.
