Influence of soil compaction on microfungal community structure in two soil types in Bartin Province, Turkey

Kara, Omer | Bolat, Ilyas

Article | 2007 | JOURNAL OF BASIC MICROBIOLOGY47 ( 5 ) , pp.394 - 399

Soil compaction negatively influences physical properties of soil (bulk density and pore space), and may consequently limit soil microfungi, which are significant for nutrient bioavailability. We measured microfungal community responses to compaction in a sandy loam and a clay loam soil at picnic sites. Soil bulk density increased significantly in the compacted samples. However, microfungal numbers and community composition were unrelated to changes in soil bulk density. With increases in bulk density from 1.22 to 1.37 g cm(-3) in the clay soil and from 1.38 to 1.54 g cm(-3) in the sandy loam soil, the total number of fungi declined . . . or showed insignificant increases. In the compacted samples as well as the control sites, the most frequently occurring genera in the clay soil were Penicillium, Aspergillus, and Gliocladium. However, the most prominent feature occurring within the sandy loam soil was the exhibition of the greatest increase in the frequency of the Fusarium genus. When comparing compacted and control soils, fungal community composition corresponded more closely within each soil texture. The two microfungal soil communities, therefore, tolerated compaction. In contrast, a difference occurred in the fungal communities between the two soil textures. This is more likely due to the variability in the controlling factors of microfungal abundance and composition, such as soil characteristics, tree species, and competitive ability of fungal genera Daha fazlası Daha az

Isolated C5 Vertebrae Dislocation with Trauma: An Extremely Rare Case of Isolated C5 Dislocation

Ozdogan, Selcuk | Kaya, Mustafa | Demirel, Nail | Duzkalir, Ali Haluk | Yaltirik, Cumhur Kaan

Article | 2017 | AMERICAN JOURNAL OF CASE REPORTS18 , pp.1256 - 1260

Objective: Rare disease Background: Total spondylolisthesis, or dislocation of 1 cervical vertebrae, is only caused by high-energy trauma and is usually fatal. Cervical spine fractures and dislocations often cause 3-column structural damage to the cervical spine, injury to the spinal cord, and precipitating alignment of the cervical vertebrae, as well as cervical instability, which are detrimental, show poor prognosis, and are associated with high rates of mortality rate and disability. Case Report: We report an extremely rare case of isolated C5 dislocation caused by falling out of a tree, with sudden tetraplegia. Conclusions: Tota . . .l spondylolisthesis or dislocation of 1 cervical vertebrae can be surgically treated with anterior approach because it is possible to completely remove the vertebra body, intervertebral disc, and bone fragments, to directly decompress the spinal cord with stabilization Daha fazlası Daha az

Ulker, Ozge C. | Yucesoy, Berran | Durucu, Murat | Karakaya, Asuman

Article | 2007 | TOXICOLOGY AND INDUSTRIAL HEALTH23 ( 3 ) , pp.155 - 160

Coal workers' pneumoconiosis (CWP) is an occupational pulmonary disease that occurs by chronic inhalation of coal dust. Coal workers' pneumoconiosis is divided into two categories depending on the extent of the disease as simple pneumoconiosis (SP) and progressive massive fibrosis (PMF). Development of CWP is associated with the activation of the immune system. Neopterin is a predictive biochemical marker of cell-mediated immune activation and elevated levels of neopterin are detected in body fluids of patients with immune-related diseases. The present study was aimed to investigate whether increased serum, urine and bronchoalveolar . . . lavage (BAL) fluid levels of neopterin is associated with the development and/or severity of CWP. Mean serum neopterin levels in SP and PMF patients (10.72 +/- 0.98 nmol/L; 14.08 +/- 3.86 nmol/L, respectively) were significantly higher than those of control group (5.30 +/- 0.47 nmol/L) (P < 0.05). Although urinary neopterin levels were also increased in SP and PMF patients (235.17 +/- 7.40 mu mol/mol creatinine; 256.05 +/- 9.43 mu mol/mol creatinine, respectively) as compared with the control group (140.00 +/- 5.43 mu mol/mol creatinine) (P < 0.01), they were within the normal concentration range. No significant difference was observed between serum and urinary neopterin levels of SP and PMF patients. A correlation was observed between serum and urinary neopterin levels of all subjects (r = 0.525, P < 0.01). Bronchoalveolar lavage fluid neopterin levels were significantly higher in patients with SP and PMF (22.67 +/- 2.9 nmol/L; 41.67 +/- 8.68 nmol/L, respectively) compared with control subjects (6.264 +/- 1.74 nmol/L) (P < 0.05, P < 0.0 1, respectively). The levels of neopterin in BAL fluid were also significantly higher in patients with PMF than in those with SP (P < 0.05). These findings indicate that elevated serum and BAL levels of neopterin may be considered as a suitable biomarker for the assessment of CWP Daha fazlası Daha az

Kilic, A | Hafizoglu, H | Kollmannsberger, H | Nitz, S

Article | 2004 | JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY52 ( 6 ) , pp.1601 - 1606

The volatiles of fresh leaves, buds, flowers, and fruits from bay (Laurus nolilis L.) were isolated by solvent extraction and analyzed by capillary gas chromatography-mass spectrometry. Their odor quality was characterized by gas chomatography-olfactometry-mass spectrometry (HRGC-O-MS) and aroma extract dilution analysis (AEDA). In fresh bay leaves 1,8-cineole was the major component, together with alpha-terpinyl acetate, sabinene, alpha-pinene, beta-pinene, beta-elemene, alpha-terpineol, linalool, and eugenol. Besides 1,8-cineole and the pinenes, the main components in flowers were alpha-eudesmol, beta-elemene, and beta-caryophylle . . .ne, in fruits (E)-beta-ocimene and biclyclogermacrene, and in buds (E)-beta-ocimene and germacrene D. The aliphatic ocimenes and farnesenes were absent in leaves. By using HRGC-O-MS 21 odor compounds were identified in fresh leaves. Application of AEDA revealed (Z)-3-hexenal (fresh green), 1,8-cineole (eucalyptus), linalool (flowery), eugenol (clove), (E)-isoeugenol (flowery), and an unidentified compound (black pepper) with the highest flavor dilution factors. Differences between buds, flowers, fruits, and leaves with regard to the identified odor compounds are presented Daha fazlası Daha az

The aim of the present study was the evaluation of possible protective effects of exercise against beta-cell damage in streptozotocin (STZ)-induced diabetes in rats. The animals were divided into five groups: the control group, the STZ-induced diabetes group, the STZ-induced diabetes and light-intensity exercise group, the STZ-induced diabetes and moderate-intensity exercise group, and the STZ-induced diabetes and heavy-intensity exercise group. Animals in the exercise groups were made to swim one of three exercise protocols once a day for 12 consecutive weeks. STZ was injected intraperitoneally at a single dose of 50 mg/kg for diab . . .etes induction. Exercise training was continued for 4 weeks prior to STZ administration; these applications were continued end of the study (for 12 weeks). Erythrocyte and pancreatic tissue malondialdehyde (MDA) levels and serum nitric oxide (NO) concentration were measured. Moreover glutathione peroxidase (GSHPx), superoxide dismutase (SOD) and catalase (CAT) were also measured in pancreatic homogenates. Pancreatic beta-cells were examined by immunohistochemical methods. STZ increased lipid peroxidation and decreased the antioxidant enzyme activity significantly. Exercise, especially moderate-intensity exercise has shown protective effect probably through decreasing lipid peroxidation and increasing antioxidant enzyme activity. Islet cell degeneration and weak insulin immunohistochemical staining were observed in STZ induced diabetic rats. Increased intensity of staining for insulin and preservation of beta-cell numbers were apparent in the exercise-applied diabetic rats. Interestingly, the best result was obtained from moderate-intensity exercise. These findings suggest that exercise has a therapeutic and/or protective effect in diabetes by decreasing oxidative stress and preservation of pancreatic beta-cell integrity.

Unique spontaneous unhealed chronic multivessel coronary artery dissection in an elderly man - A case report and review of the literature

Ozeren, A | Aydin, M | Bilge, M | Gursurer, M | Ozkokeli, M | Peksoy, I

Article | 2005 | ANGIOLOGY56 ( 3 ) , pp.335 - 338

Spontaneous coronary artery dissection (SCAD) is relatively uncommon. It often occurs in healthy, middle-aged women without overt risk factors for atherosclerosis and is associated with the peripartum period. The pattern and severity of presentation are variable. There are only 5 reports in the literature about multivessel involvement. The etiopathogenesis of SCAD is unclear. Treatment strategy is not standard but is usually tailored to clinical features. Longterm survival of patients with SCAD who have had no problem at the initial event is good. The authors report the first case of unhealed chronic multivessel SCAD in the literature.

Ozdogan, Selcuk | Yaltirik, Cumhur Kaan | Duzkalir, Ali Haluk | Demirel, Nail | Kaya, Mustafa | Atalay, Basar

Article | 2018 | AMERICAN JOURNAL OF CASE REPORTS19 , pp.249 - 253

Objective: Challenging differential diagnosis Background: The aim of this study was to draw attention to rare spinal infections in recurrent failed spinal surgeries. Case Report: A 59-year-old female was admitted to the hospital for back pain, which was assessed as a 9 on the visual analogue scale (VAS); the patient reported tiredness and night sweats. She had an operation for L3-4 far lateral disc herniation four years ago. Then another operation for L4-5 disc herniation six months ago and immediately three months later she has an operation with L3-4-5 fixation again. She had hypothyroidism, diabetes mellitus, and hypertension. Her . . . daughter was cured of pulmonary tuberculosis 20 years ago. We performed an operation by L4-5 discectomy; all granulation formation with inflammatory processes were debrided and irrigated with antibiotics at levels of L3-5. The old fixation was controlled and replaced. Her back pain improved immediately after surgery; she had a score of 2 on the VAS. Two days after her surgery, our Infection Disease Department reported acid resistant bacillus (ARB+) in samples and began anti-tuberculosis medication. Conclusions: Spinal infections should always be taken into consideration in recurrent failed back surgeries Daha fazlası Daha az

Ozdemir, H | Altin, R | Mahmutyazicioglu, K | Kart, L | Uzun, L | Savranlar, A | Davcanci, H

Article | 2004 | ARCHIVES OF OTOLARYNGOLOGY-HEAD & NECK SURGERY130 ( 9 ) , pp.1052 - 1055

Objective: To evaluate by computed tomographic scanning the paranasal mucosal changes of coal workers with and without pneumoconiosis. Methods: Examination of images and scores from paranasal computed tomographic scans. The study participants were 26 coal workers with pneumoconiosis, 29 coal workers without pneumoconiosis, and 20 controls. All were men. The extent and patterns of inflamatory paranasal sinus disease were evaluated on computed,tomographic scans by 2 radiologists using the terminology and definitions of Newman and associates. Results: Interobserver agreement for the presence of abnormalities was from good to excellent . . .(K, 0.63-0.89). The mucosal scores of individuals and groups were higher for coal workers than for control subjects. Both scores were significantly higher in the pneumoconiosis group than in the 2 other groups. Conclusions: This study shows that paranasal sinuses were affected more severely in coal workers than in control subjects. In coal workers with pneumoconiosis, the affection was most severe. The relationship between coal dust exposure and paranasal mucosal changes needs further study Daha fazlası Daha az

Altinyazar, HC | Koca, R | Tekin, NS | Esturk, E

Article | 2005 | INTERNATIONAL JOURNAL OF DERMATOLOGY44 ( 3 ) , pp.252 - 255

Background Rosacea is a common, chronic dermatosis that requires long-term therapy. Oral isotretinoin and topical and/or oral antibiotics are effective, but their usage may be limited due to side-effects. Objective The goal of the study was to compare the efficacy of topical adapalene gel (0.1%) and topical metronidazole gel (0.75%) in the treatment of patients with papulopustular rosacea. Methods This study included 55 patients with papulopustular rosacea. Diagnostic efforts were focused on clinical and histological features. Patients were randomly assigned to the adapalene (n = 30) and metronidazole (n = 25) groups. Sunlight prote . . .ction factor 20 cream was used to protect all patients from sunlight. The characteristics and numbers of inflammatory papules, pustules, erythema and telangiectasia were scored at baseline and after 2, 4, 8 and 12 weeks. Side-effects were recorded at each visit. Results Fifty patients, 27 in the adapalene group and 25 in the metronidzaole group, completed the study. Significant reductions in the total number of inflammatory lesions were found in the adapalene group compared with the metronidazole group. There was no significant difference in the scores of erythema and telangiectasia in the adapalene group. However, a significant reduction in erythema was seen in the metronidazole group. Conclusions Adapalene gel is well tolerated and can be used as an alternative for topical treatment of papulopustular rosacea Daha fazlası Daha az
