enhanced coagulation (ec) is defined as the addition of excess coagulation to improve the removal of disinfection by-product (dbps) precursors through the use of conventional water treatment processes. in this research, most of coagulants of ferric chloride (fecl3), poly aluminum chloride(pacl) in removal of most parameters of total organic carbon (toc), dissolved organic carbon (doc), organic ...

Helicobacter pylori infection of the gastric mucosa can be found in approximately 50% of the world's population and is associated with a range of pathology, including peptic ulcer, atrophic gastritis, and gastric cancer. To explore immunization as a strategy for preventing and treating H. pylori-associated disease, we assessed the safety and immunogenicity in healthy adults of a formalin-inacti...

Lymphotoxin-α (LTα) is secreted by lymphocytes and acts through tumor necrosis factor-α receptors and the LTβ receptor. Our goals were to determine whether LT has a role in obesity and investigate whether LT contributes to the link between obesity and adipose tissue lymphocyte accumulation. LT deficient (LT(-/-)) and wild-type (WT) mice were fed standard pelleted rodent chow or a high-fat/high-...

AIM To analyze records of patients listed for liver transplantation (LT) at our hospital, the first and the largest LT center in Iran. METHODS We analyzed medical records of patients aged 14 years or older, who were listed for LT for chronic liver disease between 1994 and 2004. Outcome was determined from records or follow-up data. RESULTS Among the 480 patients (mean age 39 [SD 13] years; ...

A shift in plant communities of the Water Conservation Areas (WCAs) within the Everglades has been linked to changes in hydrology and high levels of nutrient loading from surrounding agicultural areas. This has resulted in the encroachment of dense cattail stands (Typha domingensis) into areas that had previously been a ridge and slough landscape populated primarily by native sawgrass (Cladium ...

statement of problem: condylar hyperplasia of the mandible is a self limiting abnormality which can cause facial asymmetry, temporomandibular joint (tmj) dysfunction and esthetic problems. treatment planning is based on the results of isotope scanning, clinical findings and patient age. single photon emission tomography (spect) is considered to be a sensitive method in the calculation of condyl...

OBJECTIVE This study was undertaken to evaluate outcomes of redo lung transplantation (LT) for acute and chronic graft failure. METHODS Between 1988 and 2007, 388 LT procedures were performed on 369 patients. From those, 17 (4.6%) patients had redo LT once and 2 patients had redo LT twice. Patient survival and recurrence of bronchiolitis obliterans syndrome (BOS) after redo LT were reviewed. ...

Coastal bermudagrass hay was labeled with Cr by the Cr-mordant procedure and with 177Lu applied to the same fiber. Neutral detergent fiber prepared from the same Coastal bermudagrass hay was labeled with Yb, 169Yb, Tb and 160Tb by soaking overnight following by thorough washing and drying. Wood chips were similarly labeled with Sm or La, and Solka Floc was labeled with 147Nd and 141Ce. The carr...

Microscopy and permeability studies were performed to further illustrate the cooling effects on rennet casein gel structure and help interpret the rheological observations in the first part of this paper. Samples of gels cooled from 80 to 5 degrees C at four rates (0.5, 0.1, 0.05, and 0.025 degrees C/min) were studied with a confocal laser scanning microscope. A larger number of smaller flocs w...
