| the use of 16s and 16s-23s rdna to easily detect and differentiate common gram-negative orchard epiphytes. | the identification of gram-negative pathogenic and non-pathogenic bacteria commonly isolated from an orchard phylloplane may result in a time consuming and tedious process for the plant pathologist. the paper provides a simple "one-step" protocol that uses the polymerase chain reaction (pcr) to amplify intergenic spacer regions between 16s and 23s genes and a portion of 16s gene in the prokaryotic rrna genetic loci. amplified 16s rdna, and restriction fragment length polymorphisms (rflp) followi ... | 2001 | 11166101 |
| diversity of cell lengths in terminal portions of roots: location of the proliferative cell population. | terminal meristems are responsible for all primary growth of roots. it has been asserted that all cells of root meristems are actively dividing and that the stem cell (proliferative) population expands exponentially. lengths of cells in roots just proximal to the root cap/root initial boundary were used to determine the numbers of cortex and stele cells in the meristem. meristem cells were defined as cells that did not have significantly different cell lengths from initial cells at the boundary. ... | 2001 | 11165634 |
| application of clinically recorded icp patterns--an extension of conventional shunt testing. | various methods of laboratory testing are currently being used to explore the hydrodynamic properties of shunts. we constructed a novel shunt-testing rig with a human-like compliance to be able to subject shunts to in-vivo recorded icp patterns. the human-like situation was realized with a pear-shaped glass container with a non-linear, third-order pressure/volume characteristic similar to the csf system. the new device also allows conventional shunt testing. shunt performance in conventional pre ... | 2000 | 11156301 |
| isolation and characterization of five erwinia amylovora bacteriophages and assessment of phage resistance in strains of erwinia amylovora. | phages able to infect the fire blight pathogen erwinia amylovora were isolated from apple, pear, and raspberry tissues and from soil samples collected at sites displaying fire blight symptoms. among a collection of 50 phage isolates, 5 distinct phages, including relatives of the previously described phages phiea1 and phiea7 and 3 novel phages named phiea100, phiea125, and phiea116c, were identified based on differences in genome size and restriction fragment pattern. phiea1, the phage distribute ... | 2001 | 11133428 |
| prototypical profiles of the brief psychiatric rating scale. | three prototypical profiles of the brief psychiatric rating scale (bprs; overall & gorham, 1962) were isolated using a q-type factor-analytic strategy with a sample of homeless men with mental illness (n=165). the 3 profiles--depressed, actively psychotic, and withdrawn--were used to study changes in bprs profiles over time in a control group and a group that received assertive community treatment (act). over2 time periods (inception to 12 months and 12-24 months), the 2 groups did not differ in ... | 2000 | 11117152 |
| the neuronal structure of the substantia nigra in the guinea pig: nissl and golgi study. | the studies were carried out on the mesencephalos of adult guinea pigs. the preparations were made by means of the golgi technique, as well as the nissl and klüver-barrera methods. four types of neurons were distinguished in the substantia nigra (sn) of the guinea pig: 1. bipolar neurons of two kinds: the neurons of the first kind have elongated, fusiform perikarya (25-40 microns), whereas the cells of the second kind have rounded and oval perikarya (15-22 microns). these neurons possess two den ... | 2000 | 11107698 |
| reduction in paraquat embryotoxicity by ascorbic acid in xenopus laevis. | the toxicity of herbicide paraquat (pq, 1-1'-dimethyl-4,4'bipyridylium dichloride) in animal cells is related to its rapid reduction and instantaneous reoxidation to produce the reactive oxygen species. recently, the pq evaluation with the frog embryo teratogenesis assay-xenopus (fetax) showed its high embryotoxicity. supposing that the embryos' death was due to pq-related oxidative damage, we used ascorbic acid (aa), a well known antioxidant, to reduce the pq embryotoxicity in xenopus laevis. e ... | 2001 | 11090891 |
| heterogeneity of fish taste bud ultrastructure as demonstrated in the holosteans amia calva and lepisosteus oculatus. | taste buds are the peripheral sensory organs of the gustatory system. they occur in all taxa of vertebrates and are pear-shaped intra-epithelial organs of about 80 microm height and 50 microm width. taste buds mainly consist of specialized epithelial cells, which synapse at their bases and therefore are secondary sensory cells. taste buds have been described based on studies of teleostean species, but it turned out that the ultrastructure of teleostean taste buds may differ between distinct syst ... | 2000 | 11079403 |
| angiomatous skeletal lesions. | vascular lesions involving osseous structures are relatively common neoplasms. we will review the appearance of many musculoskeletal angiomatous lesions using the multimodality approach. lesions to be discussed include osseous hemangioma, glomus tumor, angiomatosis and associated syndromes (osler-weber-rendu, klippel-trenaunay-weber, and kasabach-merritt), gorham, tumor-induced osteomalacia, and aggressive vascular neoplasms (hemangioendothelioma, hemangiopericytoma, and angiosarcoma). | 2000 | 11061695 |
| jagged2 induces cell cycling in confluent fibroblasts susceptible to density-dependent inhibition of cell division. | jagged2 is a member of the dsl (delta-serrate-lag-2) -ligand family of transmembrane proteins that signal through the notch receptors. in many cases of human acute lymphoblastic t-cell leukemias, chromosomal translocations fuse a part of the notch-1 gene to the t-cell receptor-beta locus (ellison et al., 1991, cell 66:649-661). the truncated notch-1 allele encodes an aberrant protein that lacks most of the extracellular domain and is constitutively activated (pear et al., 1996, j exp med 183:228 ... | 2000 | 11056013 |

| structural and functional complexity of the genomic region controlling ak-toxin biosynthesis and pathogenicity in the japanese pear pathotype of alternaria alternata. | the japanese pear pathotype of alternaria alternata produces host-specific ak-toxin and causes black spot of japanese pear. previously, a cosmid clone, pcakt-1, was isolated that contains two genes, akt1 and akt2, within a 5.0-kb region required for ak-toxin biosynthesis. the wild-type strain has multiple, nonfunctional copies of these genes. in the present study, two additional genes, aktr-1 and akt3-1, downstream of akt2 were identified. transformation of the wild type with aktr-1- and akt3-1- ... | 2000 | 10975654 |
| transgenic expression of pear pgip in tomato limits fungal colonization. | transgenic tomato plants expressing the pear fruit polygalacturonase inhibitor protein (ppgip) were used to demonstrate that this inhibitor of fungal pathogen endopolygalacturonases (endo-pgs) influences disease development. transgenic expression of ppgip resulted in abundant accumulation of the heterologous protein in all tissues and did not alter the expression of an endogenous tomato fruit pgip (tpgip). the ppgip protein was detected, as expected, in the cell wall protein fraction in all tran ... | 2000 | 10975651 |
| purification and characterization of a nad+-dependent sorbitol dehydrogenase from japanese pear fruit. | nad+-dependent sorbitol dehydrogenase nad-sdh, ec 1.1.1.14) from japanese pear fruit was purified to apparent homogeneity (single band by sds-page with silver staining), and had a specific activity of 916.7 nkatal/mg protein. the molecular of the native enzyme was calculated to be 160 kda by gel filtration, whereas sds-page gave a subunit size of 40 kda, indicating that the native enzyme is a homotetramer. the protein immunologically reacted with an antibody raised in rabbit against the fusion p ... | 2000 | 10963448 |
| [effect of a selective agent and a plant intron on the effectiveness of transformation and expression of heterologous genes in the pear (pyrus communis l.)]. | the effect of selective agents on the efficiency of agrobacterium-mediated transformation of pear was shown. the transformation frequency of the pear stock ps no. 217 by a binary vector carrying the nptii gene conferring kanamycin resistance was 0.4 or 3.1%, while the hpt gene for hygromycin resistance used as a selective marker increased transformation frequency to 6.2 (11.5%). in addition, upon selection on hygromycin b, the proportion of pseudotransgenic regenerants considerably decreased. in ... | 2000 | 10923261 |
| laboratory rearing of lesser appleworm (lepidoptera: tortricidae). | the lesser appleworm, cydia prunivora (walsh), was reared successfully in the laboratory. larvae of various instars were collected in the field from hawthorn fruit, crataegus spp. initially, immature apples served as the food source for the larvae in the laboratory. rearing was conducted in a greenhouse and later in combination with a controlled environment room at 25 degrees c, 50-60% rh, and a photoperiod of 18:6 (l:d) h. under these conditions, a generation required approximately 30 d. fifty- ... | 2000 | 10902366 |
| particle films for suppression of the codling moth (lepidoptera: tortricidae) in apple and pear orchards. | studies were conducted in 1997 and 1998 to evaluate the effects of three particle film formulations consisting of kaolin and adjuvants on neonate larvae, ovipositing adult females, and eggs of the codling moth, cydia pomonella (l.). neonate larval walking speed, fruit discovery rate, and fruit penetration rate on apple host plants coated with particle films were significantly lower than on host plants without particle films in laboratory assays. females oviposited less on host plants covered wit ... | 2000 | 10902324 |
| perimeter trapping strategy to reduce mediterranean fruit fly (diptera: tephritidae) damage on different host species in israel. | to evaluate the perimeter trapping strategy as a control method, field tests were conducted in three different host species of the mediterranean fruit fly, ceratitis capitata (wiedemann), in israel. dry traps baited with a three component food-based synthetic attractant that were hung in the peripheral rows of a plum, a pear, and a persimmon orchard, caught female c. capitata (up to 20.1, 1.4, and 4.1 female c. capitata per trap per day, respectively). fruit damage, estimated at harvest, indicat ... | 2000 | 10902321 |

| babesiosis. | babesiosis is an emerging, tick-transmitted, zoonotic disease caused by hematotropic parasites of the genus babesia. babesial parasites (and those of the closely related genus theileria) are some of the most ubiquitous and widespread blood parasites in the world, second only to the trypanosomes, and consequently have considerable worldwide economic, medical, and veterinary impact. the parasites are intraerythrocytic and are commonly called piroplasms due to the pear-shaped forms found within inf ... | 2000 | 10885987 |
| g proteins mediate changes in cell shape by stabilizing the axis of polarity. | upon exposure to mating pheromone, yeast cells change their form to pear-shaped shmoos. we looked at pheromone-dependent cell shape changes in mutants that are unable to orient growth during mating and unable to choose a bud site. in these double mutants, cell surface growth, secretion sites, cytoskeleton, and pheromone receptors are spread out, explaining why these cells are round. in contrast, polarity establishment proteins localize to discrete sites in these mutants. however, the location of ... | 2000 | 10882121 |
| the gorham-stout syndrome (gorham's massive osteolysis). a report of six cases with histopathological findings. | the gorham-stout syndrome (gorham's massive osteolysis) is a rare condition in which spontaneous, progressive resorption of bone occurs. the aetiology is poorly understood. we report six cases of the condition and present evidence that osteolysis is due to an increased number of stimulated osteoclasts. this suggests that early potent antiresorptive therapy such as with calcitonin or bisphosphonates may prevent local progressive osteolysis. | 1999 | 10872375 |
| multiresidue method for the determination of residues of 251 pesticides in fruits and vegetables by gas chromatography/mass spectrometry and liquid chromatography with fluorescence detection. | a method is described for the determination of 251 pesticide and degradation product residues in fruit and vegetable samples. extraction of the sample with acetonitrile is followed by a salting-out step. co-extractives are removed by passing a portion of the acetonitrile extract through an octadecyl (c18) solid-phase extraction cleanup cartridge and then, in a second cleanup, through a carbon cartridge coupled to an amino propyl cartridge. determination is by gas chromatography with mass-selecti ... | 2008 | 10868594 |
| chronology of the appearance of beta, a, and alpha mitochondria-rich cells in the gill epithelium during ontogenesis of the brown trout (salmo trutta). | three types of mitochondria-rich (mr) cells, the alpha, beta, and accessory cells, are observed in the gill epithelium of juvenile and adult freshwater teleosts. in addition to numerous mitochondria, their cytoplasm contains a network of membranous tubules, the tubular system, connected to the laterobasal plasma membrane. because they are believed to play a role in ionic regulation, it is of interest to examine the order of appearance and the ultrastructural characteristics of such cells during ... | 2000 | 10861363 |
| types of neurons of the subthalamic nucleus and zona incerta in the guinea pig--nissl and golgi study. | the studies were carried out on the subthalamus of adult guinea pigs. golgi impregnation, nissl and klüver-barrera methods were used for the study. in nissl stained sections the subthalamic neuronal population consists of multipolar, fusiform, oval and pear-shaped perikarya. in two studied areas: nucleus subthalamicus (stn) and zona incerta (zi) three types of neurons were distinguished. type i, multipolar neurons with quadrangular, triangular or oval perikarya. they have 3-6 primary dendrites w ... | 2000 | 10859880 |
