Our results showed that limbal conjunctival autografting is an effective surgical technique for the treatment of pterygium, and tissue glue was efficacious in securing the limbal conjunctival autograft in pterygium surgery. The use of tissue glue decreases patient symptoms during the postoperative period after pterygium surgery. Compared with sutures, tissue glue had no adverse effects on ocular tissue.

Aspergillosis; Aspergillus flavus; pseudo-nodular infiltrate in the right upper zone and a somewhat enlarged left hilum (Figure 1). Bronchoscopy membranous bronchitis; pseudomembranous necrotizing bronchial aspergillosis; renal transplantation; was performed on day 11 in order to obtain specimens for microbiological examination. Raised, cream-tracheobronchitis colored membranous plaques were observed to cover the bronchial mucosa in the distal trachea, the apical segment of the right upper lobe, and the distal half of

Results suggest that the occult metastasis rates are higher than those detected with routine hematoxylin-eosin staining. However, because it is accepted that neck dissection alone has adequate therapeutic efficiency in pN1 patients, the detected 13.61% rate of micrometastases has not changed our treatment plan in the neck.

Our finding TA muscle invasion at the rate of 31.2% in our 16 case series clinically staged as T1 revealed that deep invasion did not always impair the vocal cord mobility. Observing TA muscle invasion at the rate of 50% in cases involving the one-third anterior part of the vocal cord and the anterior commissure suggested that TA muscle invasion in the anterior part did not significantly impair mobility.

Loss of KAI-1 may be considered a significant prognostic parameter in predicting the progression of the gastric carcinomas when evaluated along with the clinical and pathological parameters.

IntroductionMany ions can be found in water as dissolved, absorbed/ adsorbed, or suspended matter, and the content of the ions determines whether the water is polluted. Some of the components in water can be recognized as exceeding safe limits or toxic. Wastes in open and partially enclosed quarries left behind after mining operations contain metals or toxic trace elements, and drainage waters that are rich in elements can mix into the surface water. These elements can be carried by acid water downstream and run-off to the sea, as either dissolved species or an integral part of suspended material, resulting in numerous environmental problems (Duruibe et al., 2007 and references therein).The oxidation of sulfide minerals, e.g., pyrite, chalcopyrite, sphalerite, and galena, exposed to atmospheric oxygen during or after mining operations produces acidic waters with high concentrations of dissolved iron, sulfate, and metals or semimetals, thus posing a health hazard to humans (Mrozek et al., 2006 and reference therein). Acid mine drainage (AMD) may cause environmental pollution by the dissolution and contamination of hazardous elements in aqueous systems.The investigation area is situated in a metallogenic area in the Black Sea region, NE Turkey (Figures 1 and 2). This area comprises approximately 400 Cu-Zn-Pb sulfide deposits of various sizes and types. The variable sizes of the VMS deposits are tectonically controlled in the Eastern Black Sea region and are hosted by hydrothermally altered peripheral zones in the Maastrichtian-Eocene volcanics.Although some of the mines were abandoned hundreds of years ago, the impact of AMD continues. Drainage from the ores and their host rocks, abandoned mines, and wastes have been polluted and regularly discharged into surface waters. The mixing of these waters into the ground and surface waters has resulted in serious problems or undesirable effects for all living things in the area. Due to the wet climate conditions and rainfall in the Black Sea region, streams flow throughout the year. The waters with low pH can leach some heavy metals, such as As, Cd, Pb, Sb, and Tl, and some toxic trace elements, such as Al, Cu, Fe, Se, and Zn, from the ores and host rocks. In the study area, the polluted rivers' and streams' surface waters have been used in agriculture and animal husbandry. Thus, the dissolved or suspended metals and
