Acknowledgments We thank the New Hampshire State Health Department for its support in this research. At the time of this study, he was a postdoctoral research fellow in the Department of Plant, Soil, and Insect Sciences at the University of Massachusetts. His research focuses on the evolutionary ecology of bacterial pathogens that cause human illness, particularly environmental and host dynamics that govern pathogen emergence in natural populations. Terio, Stacy Schultz, and Ann Pabst Lacazia loboi, a cutaneous fungus, is found in humans and dolphins from transitional tropical (Florida) and tropical (South America) regions. We report 2 cases of lobomycosis in stranded bottlenose dolphins (Tursiops truncatus), and 1 case of lobomycosis-like disease in 1 free-swimming, pelagic, offshore bottlenose dolphin from North Carolina, where no cases have previously been observed. On the basis of overall length, rostrum length, and flipper size, the dolphin was identified as belonging to the offshore ecotype (9). Gross findings included numerous serpiginous and coalescing, raised, ulcerated-to-papillary nodules on the dorsum anterior to the dorsal fin and extending to the mid-body (Figure 1, panel A). Other gross lesions included verminous pterygoid sinusitis and pneumonia and mild dermal and retroperitoneal cestodiasis. Dermal and subcutaneous granulomas composed of multinucleated giant cells, epithelioid macrophages, lymphocytes, and plasma cells were present in all skin sections and surrounded yeast-like structures. Fungi (6­10 m) were connected in chains to adjacent fungal bodies by a thin neck (Figure 1, panel B). Other findings included parasitic migratory tracts in the brain, parasitized lungs, and pterygoid sinuses. Infection results in dermal and subcutaneous granulomas and 6­12-m yeast-like bodies connected in chains by a small tubule (2); spread by the lymphatic system has been reported (3). Hematogenous spread and contiguous spread have not been excluded as means of propagation. Infections have been reported in humans (4) and dolphins, including Guiana dolphins (Sotalia guianensis) in tropical climates (Latin America) (5) and Atlantic bottlenose dolphins (Tursiops truncatus) in transitional tropical climates (Indian River Lagoon and Gulf of Mexico, Florida; Matagorda Bay, Texas; and Bay of Biscay, Europe) (6­8). We report 2 cases of lobomycosis in offshore (pelagic) bottlenose dolphins stranded off North Carolina in 2005 and 2008. B) Gomori methenamine silver­stained sections of dermis showing yeast-like structures connected by neck and arranged at various angles (magnification Ч400). Amplicons were sequenced at the University of Chicago Cancer Sequencing Facility and were most closely (97%) related to Paracoccidiodes brasiliensis. The most obvious gross finding was a few ulcerated dermal nodules scattered across the dorsum. The dolphin also exhibited nonsuppurative meningoencephalitis, bronchointerstitial pneumonia, necrotizing hepatitis, and necrotizing adrenalitis associated with Toxoplasma spp. Live Sighting On May 26, 2008, a free-swimming offshore bottlenose dolphin was sighted by a vessel survey team from Duke University Marine Laboratory at 35. The animal had a large region of raised epidermal gray to white nodules over the entire dorsal surface cranial to the dorsal fin. These lesions are consistent with those seen in the other bottlenose dolphins in this report and lesions seen on bottlenose dolphins from the Indian and Banana rivers in Florida (10). The location of this sighting suggests that this dolphin is of the offshore ecotype (11,12). Conclusions Lobomycosis has been reported in the United States in coastal bottlenose dolphin populations in the Indian River Lagoon on the eastern coast of Florida, in the Gulf of Mexico off the western coast of Florida, and off the Texas Gulf coast. The Indian River Lagoon dolphin population has been assessed for temporal and spatial prevalence of lobomycosis (10). The number of new cases per year, as determined from photograph identification studies, ranged from 1 to 9. The cases in 2 stranded dolphins and in 1 photographed dolphin occurred in a subtropical climate of North America and involved an offshore rather than a coastal species.

Although many patients developed recurrent periodontal problems during recall heart attack full movie buy 100 mg labetalol with amex, only 15 arteria yugular funcion generic labetalol 100mg on line. Teeth originally given a doubtful prognosis often were responsible for recurrent problems and sometimes required extraction blood pressure 220120 cheap labetalol 100 mg without prescription. The 12-year study of 225 randomly selected patients offered annual preventive care at 12 community dental clinics in Sweden indicated an overall low incidence of tooth loss (0. A decrease in gingival scores from 15% to 4% was also observed, with no change in probing depth. Tooth site analysis revealed that buccal sites had more loss of attachment than lingual and approximal surfaces. Radiographic assessment of the alveolar bone height revealed a mean longitudinal loss of 0. The mean longitudinal changes were similar in all age groups, showing that therapy provided was equally effective in all age groups, although differences in rate of deterioration may be due to individual differences in environmental or disease conditions. Almost all patients (96%) had at least 1 site with > 2 mm of attachment loss during the 12 years of follow-up. Seventy-eight (78) patients were treated and maintained with 3 month recalls over a period of 8 years. Variations in probing depth and attachment levels were related to individuals with plaque scores above and below the median. Results indicated personal oral hygiene, based on plaque scores, was not critical for maintenance of post-treatment probing depth and attachment levels in patients receiving professional tooth cleanings every 3 months over the 8 years. After 1 year, there was no indication that individuals with poor oral hygiene had any greater loss of attachment than those with good oral hygiene. For probing depths 1 to 3 mm and 4 to 6 mm there was no difference in pocket reduction maintenance. The authors concluded that the severity of recurrent gingivitis with 3-month recall and maintenance following therapy had little effect on probing depth and attachment level. Pertinent factors include patient education, oral hygiene reinforcement, full-mouth radiographs every 2 years, and 2 to 3 month recall intervals. The hygienist is an indispensable aid to the periodontist in preventive treatment, but a thorough examination of the occlusion and gingival crevice is necessary. In a subsequent article, Chace (1967) indicated that the general dentist who participates in the maintenance of periodontal patients assumes far greater responsibilities than he does in the care of the average patient. This requires an understanding of periodontal pathology, basic periodontal procedures, techniques necessary for the use of fine curets, and time demands of preventive treatment. Chace (1977) also suggested that patients treated for periodontal disease may be susceptible to recurrent periodontitis. Some patients tend to have recurrences despite exemplary care, necessitating retreatment. Reasons for regression must be thoroughly evaluated and may include oral hygiene regimen, surgical technique, occlusal factors, and systemic factors. Patients should be prepared psychologically and informed of the possibility of additional future treatment. Surgical retreatment should be performed if indicated, but if the deepened crevice does not bleed when probed and is not accompanied by bone loss surgery is not justified. Based on epidemiologic studies, Schick (1981) noted that a maintenance program should provide adequate therapy for previously existing periodontal conditions. Initially, the patient should be provided with a thorough prophylaxis and complete reinforcement instructions in oral hygiene procedures every 3 months. The 3-month interval should be increased, maintained, or decreased depending on an evaluation of the stability of the supporting structures. Close monitoring will indicate the appropriate time interval for each individual patient, and if necessary retreatment determined for those areas that may be deteriorating. The authors indicate that prevention of periodontal disease occurs at 3 levels: preventing the inception of disease; preventing progression of existing disease; and preventing recurrence of disease following treatment.

Various fly ash heart attack jim jones labetalol 100 mg without a prescription, lime levels and their interaction significantly influenced the available P content of soil under rice blood pressure top number high quality labetalol 100mg. However arteria tapada del corazon purchase labetalol 100 mg on-line, at postharvest stage, the lowest level of available P was noted irrespective of treatments. The residual effect of application of different amounts of fly ash failed to influence the available P content of soil, while lime increased available P in the soil under lettuce. Available K content of the soil was increased due to fly ash and lower rate of lime. Fly ash at all levels significantly increased the grain yield while it increased the straw yield only at the highest level. The highest level of fly ash and lime significantly increased lettuce yield while the interaction between the two was not significant. The P uptake by rice grain as well as lettuce was significantly influenced by both levels of fly ash and the highest level of lime. The different levels of lime failed to influence K uptake by rice grain and lettuce while it was highly significant for rice straw. Growth and yield of cymbopogon martinii as influenced by fly ash, am fungi inoculation and farmyard manure application.

Sludge was stabilized by mixing with fly ash at an amendment rate of 0, 5, 10, 35 and 50% (w/w) before undergoing a short fermentation period to produce a range of ash-sludge fertilizer product. Each mixture was then mixed with a loamy soil at either 1: 1 or 1: 5 ash-sludge mixture: soil (v/v). Dry weight yields of pots receiving 1: 5 ash-sludge: soil mixture (v/v) were significantly higher than their counterparts with a soil mixing ratio of 1: 1 (v/v). The highest yields were obtained at 5 and 10% ash-sludge mixture amended soil at 1: 5 soil mixing ratio. Nevertheless, the yield at 35% ash-sludge amended loamy 79 Use of Industrial Byproducts in Agriculture soil at 1: 1 v/v was still higher than that of the control soil with fertilizer treatment. The nutrient content of maize seedlings was higher at 35 and 10% ash-sludge mixture amended soil at 1: 1 v/v, and 5 and 10% at 1: 5 v/v than other treatments. Zinc concentrations of maize seedlings increased while B decreased with the decreasing amounts of fly ash added. Hence, the present experiment demonstrates the beneficial effects of the ash-sludge mixture on soil nutrient status and plant root growth environment. An ash amendment rate of up to 35% in the ash-sludge mixture would not have any adverse effects on plant production even at a high soil mixing volume of 1: 1 (v/v), but an addition of 5 to 10% ash-sludge mixture at 1: 5 (v/v) produced the optimum condition for maize seedlings growth. The results support the use of coal fly ash as a stabilizing agent for sewage sludge and the product could be used for land application. Growth parameters in tomato and spinach as influenced by fly ash, soil and their combinations. Tomato growth (height) was reduced by fly ash (alone or in combination with soil), but a fly ash:soil ratio of 1:1 increased the number of leaves and number of branches above control values. On a dry matter yield basis, a fly ash:soil ratio of 1:3 promoted dry matter accumulation in both crops. Use of such contaminated sites for crop production and use of contaminated water for irrigation not only decreases crop productivity but also poses health hazards to humans due to accumulation of toxic metals in edible grains. Accumulation of Fe, Si, Cu, Zn, Mn, Ni, Cd and As was investigated in roots, leaves and seeds of the plants. Fe accumulation was maximum in all the parts of plant followed by Si and both showed more translocation to leaves while Mn, Zn, Cu, Ni and Cd showed lower accumulation and most of the metal was confined to roots in all the three cultivars. As was accumulated only in leaves and was not found to be in detectable levels in roots and seeds. The metal accumulation order in three rice cultivars was Fe > Si > Mn > Zn > Ni > Cu > Cd > As in all the plant parts. Growth rate of fenugreek plant, Trigonella foenumgraecum, as influenced by fly ash. Different concentrations of fly ash in the soil were given: 0, 25, 50, 75 and 100%. The fly ash amendment up to 50% increased the total fresh and dry weights of treated plants compared to the plants grown in fly ash-free soil. However, the highest increase of 11% in the plant fresh and dry weights was recorded upon treatment with 25% fly ash.

B-lymphocytes differentiate and become antibody-producing plasma cells blood pressure in elderly order labetalol us, while T-lymphocytes are involved in a variety of cell-mediated immune reactions blood pressure medication vertigo order 100mg labetalol mastercard. Lymphokine: Soluble factors released from lymphocytes that transmit signals for growth and differentiations of various cell types blood pressure chart by time of day purchase labetalol 100 mg on line. Important as an antigen-presenting cell and as a producer of certain cytokines such as interleukin-1 and gamma interferon. Neutrophil: the predominant polymorphonuclear leukocyte comprising up to 70% of the peripheral white blood cells that is important in infection and injury repair. It can be activated by the complex or "classical" pathway (initiated by antigen bound to IgG or IgM which in turn is bound to the first component of complement) and the properdin or "alternate" pathway (activated by bacterial endotoxins and certain other substances). The anaphylatoxic and chemotactic factors of activated complement (C3a and C5a) are produced in both pathways. Immunological mechanisms which can protect the host against infectious organisms may also cause tissue destruction. An exception to this is polyclonal B cell activation in which certain substances activate B cells without regard to their antigenic specificity. Activated cells either differentiate into effector (or plasma) cells or become "memory" cells which can mount a much stronger second response to an antigen. Host tissue damage can result from immune response when oral bacteria and their products gain access to the gingival connective tissue and react with specific T and B cells which release lymphokines. Additionally, immunoglobulins produced by plasma cells can activate the complement system with potential destructive effects. When components of the immune system are activated, the ensuing inflammatory response is accompanied by some degree of tissue destruction. The immune systems responding to bacterial infections include the mucosal or secretory immune system, neutrophil-antibody-complement system, lymphocyte-macrophage system, and immunoregulatory systems. Microbial killing may result from complement-dependent cytolysis/complementantibody mediated cytolysis and phagocytes functioning independently or in combination with opsonic factors such as antibody and complement. Phagocytes can increase bactericidal activity through oxygen reduction, excitation mechanisms, or oxgyen independent mechanisms such as lysosome, lactoferrin, and azurophilic granules. Serum antibody studies have shown correlations between predominant organisms in several forms of periodontal disease and antibody titers. Complement plays an extensive role in periodontal disease through its effects on phagocytosis, chemotaxis, alteration of vascular permeability, killing of cells, lymphokine production, antibody synthesis, lysosomal enzyme release, and bone resorption. Complement proteins (or cleavage products) bind to receptors on neutrophils, platelets, mast cells, macrophages, erythrocytes, and specific target cells. Hypersensitivity to periodontopathic microbial antigens has been demonstrated using lymphokine production or the blastogenesis assay as in vitro indicators of cellular immunity. Three patterns of reactivity of peripheral blood monocytes following stimulation by oral organisms have been suggested: 1) specific or non-specific stimulation of lymphocyte blastogenesis by mitogenic or polyclonal activation of lymphocytes, regardless of disease activity level; 2) peripheral blood lymphoproliferative response, in a few individuals with non-categorized disease status; and 3) stimulation of more positive responses by Gram-negative anaerobic organisms. The lymphoproliferative response results in a production of lymphokines, such as alpha-lymphotoxin and osteoclast activating factor, which may in turn produce tissue destruction. Lymphocytes can induce macrophage activation to produce tissue destructive factors such as collagenase and oxidizing agents. It has been observed that patients with deficient lymphocyte functions have less gingival disease than immunocompetent patients, but patients with reduced neutrophil numbers or function are very susceptible to disease. Lymphocytes and macrophages also produce factors which recruit fibroblasts to areas of inflammation and lead to their proliferation. Miyasaki (1991) reviewed the role of the neutrophil in controlling periodontal bacteria. Neutrophils kill bacteria or influence bacterial growth by oxidative (cytosol, membrane granules) or non-oxidative mechanisms (azurophil granules, defensins). Delivery of antimicrobial substances by the neutrophil can occur by 4 mechanisms: 1) delivery of oxygen metabolites or so-called "respiratory burst" (this occurs as phagocytes consume and transfer dioxygen resulting in superoxide and hydrogen peroxide production); 2) secretion which involves release of cytoplasmic granule contents as a result of fusion of granules with the plasma membrane; 3) phagocytosis by engulfment of particles within a membrane bound structure called a phagosome; phagosomes fuse with lysosomes to form phagolysosomes, which effectively deliver high concentrations of granule contents; and 4) death as a result of injury or failed phagocytosis (cytolysis) or as a result of programmed cell death (apoptosis). Miyasaki also described the "order" of components of the host defenses in response to a bacterial challenge. Initially protection is afforded by serum complement; activation of complement produces an influx of neutrophils. All of these responses are an attempt of the body to contain the bacterial antigen.
