Bilateral calcaneal intraosseous lipoma: A case report

WOS: 000173416400012PubMed: 11822695Intraosseous lipoma is a rare benign primary lesion of bone. Approximately 180 cases have been reported to date. In the literature, we have been able to find only three patients with bilateral calcaneal involvement. We present a 34-year-old woman who was diagnosed with intra-osseous lipoma in both calcanei

INDUCED SYSTEMIC RESISTANCE AGAINST FUSARIUM WILT OF TOMATO BY RHIZOBACTERIAL ISOLATES

Plant growth-promoting rhizobacteria (PGPR) include bacteria in the soil rhizosphere that promote plant growth and development through a wide variety of mechanisms. In this study, potential effects of three rhizobacteria Bacillus subtilis (57-2), B. mojavensis (36-1) and B. pseudomycoides (80-1) isolated from tomato rhizosphere on induction of resistance to Fusarium oxysporum f. sp. lycopersici (Fol) were examined through biochemical and histological analyses. These PGPR isolates significantly reduced Fusarium wilt incidence up to 70%. However, the combination of isolates was found either less or not effective in suppressing the disease severity when compared to those of application by the individual isolates. The induction of peroxidase (PDX, EC 1.11.1.7) and catalase (CAT, 1.11.1.6) enzymes was found to be significantly higher in treatment groups than in comparison with the control group. Present biochemical study revealed that three Bacillus spp. resulted in great accumulation of proline and key defense enzymes (PDX and CAT). In situ studies also demonstrated that hydrogen peroxide (H2O2) accumulation and the callose deposition at reaction sites as a response to the pathogen attack reached to maximum level, 24 h after pathogen inoculation. The present findings revealed that PGPR isolates could be effectively used for the biocontrol of Fol through enhancing disease resistance responses of tomato plants

POTENTIAL OF PSEUDOMONAS AND BACILLUS ISOLATES AS BIOCONTROL AGENTS AGAINST FUSARIUM WILT OF EGGPLANT

Plant growth-promoting rhizobacteria (PGPR) are beneficial bacteria found on plant roots that induce growth by a wide variety of mechanisms. Ten isolates of Pseudomonas and Bacillus were isolated from eggplant rhizosphere soil and evaluated for their volatile compound efficacy against mycelial growth of Fusarium oxysporum f. sp. melongenae (Fomg) and tested for their ability to colonize eggplant (Solanum melongena L) roots in vitro. PGPR strains inhibited mycelial growth of the target pathogen and the percentage of inhibition varied from 38 % to 72 % by means of inhibitory activities. Pseudomanas aeruginosa (P07-1) and putida (P11-4) were determined to be successful colonizers in eggplant seedlings. Also, a pot experiment was conducted to assess the induced resistance to Fusarium wilt of eggplant by PGPR strains. Among the PGPR isolates, P aeruginosa (P07-1), P putida (P11-4), P aeruginosa (85A-2), Bacillus amyloliquefaciens (76A-1) and B. cereus (B10a) significantly reduced Fusarium wilt disease incidence by up to 85 %. However, their combination was not more effective in suppressing the disease than the application of those isolates alone. The induction of peroxidase (PDX EC 1.11.1.7) and polyphenol oxidase (PPO, EC 1.14.18.1) enzymes was found to be significantly higher in comparison with the control group. Similarly, the proline levels in eggplants showed an increasing trend with the above isolates. However, catalase (CAT, 1.11.1.6) activity was not found to significantly contribute to the induced resistance mechanism. This study revealed that the promising PGPR isolates could be potentially very useful for the biocontrol of Fomg via enhancing disease resistance in eggplant plants

Vulnerability of Marmaris-Fethiye coasts, SW Turkey

One of the likely consequences of global climate change is an accelerated global sea-level rise. Combined with other effects, such as land subsidence, storm impacts and tsunamis, it could cause serious increases in coastal vulnerability, such as loss of the shore zone accompanied by a dramatic reduction of the width of the beaches. The deltaic areas and low-lying coastal plains along the Marmaris-Fethiye coast, SW Turkey, are experiencing a number of similar short- And long-term coastal problems. In addition historical earthquakes and tsunamis hit those areas many times in the past. Trenching and coring surveys for historical tsunami deposits, their geological and biochemical properties provided some new clues for the coastal vulnerability of the studied coast to tsunamis, as well as for the environmental assessment of the past

New approaches in assessment of tsunami deposits in Dalaman (SW Turkey)

Some earthquakes in the Eastern Mediterranean are tsunamigenic, and some of their tsunamis affected the coastal area of the Gulf of Fethiye, SW Turkey. Recent trenching surveys on the low-lying coastal areas of Dalaman delta beach across the Rhodes Pass revealed three probable tsunami impacts as a result of the historical earthquakes of 1303, 1481, and 1741. Yet there have been relatively few studies of the processes associated with tsunami sediment transport, their deposition, and nature in geological record. In addition to the interpretation of sedimentary features, accurate palaeo-environmental assessments might be possible by distinctive biogeochemical researches on marine-sourced organic matters, geochemical properties, quantitative amounts of marine biomarkers, and deterministic ratios. The identification of major lipid biomarkers (fatty acids and sterols) in the samples recovered from the sidewalls of the studied trench, for example, indicated biogenic contributions due to the presence of phytoplankton, zooplankton, bacteria, and dinoflagellates. Quantitative estimation of biomarkers and deterministic ratios also indicated some evidences for marine-sourced organic matters, implying that biomarkers can be used to answer the open questions in tsunami and palaeo-tsunami researches
