Patients and methods: Ten normal subjects with obstructing concha bullosa and twenty adult CRS patients who failed medical treatment and subjected for endoscopic sinus surgery were enrolled in this prospective controlled study: 10 patients with (CRSwNP) and 10 patients with (CRSsNP). Scanning electron microscopy (SEM) was done for paranasal sinuses tissue samples. Bacteriological culture and study of bacterial adherence using tissue culture plate method which was measured quantitatively by a...
In carrying oxygen hemoglobin binds the oxygen in its structure as follows and then it is transported through the red blood cells to the needy tissues. When the hemoglobin is oxygenated is assumes a planar shape while deoxygenated hemoglobin has a non planar shape usually called a domed shape. The oxygenated blood is bright red while the deoxygenated blood is somehow bluish. Hydrogen and carbon dioxide regulate the release of oxygen in a process called Bohr's effect which is a process named...
Transamination is an enzyme coupled reaction that, if not in the presence of the specific transaminase will not occur. The transamination performed by Glutamate-pyruvate-transaminase (GTP; EC 2.6.1.2) functions on α-keto acids and amino acids to synthesis new amino acids and a new α-keto acid. GPT functions on pyruvate and glutamate to create alanine and α-ketoglutrate. The enzyme requires the cofactor pyridoxal-5-phosphate which acts a coenzyme by transferring the amino group between the...
Food can only be considered unsafe when it comes into contact with contaminants or hazards Motarjemi Nout, 1996; Kitagwa, 2005. These hazards are described as any biological, chemical or physical substance that supports the growth or survival of micro-organisms and toxins in food which causes spoilage leading to illness (USAD, 1999; WHO 1992). The presence of these harmful substances in foods above an established acceptable level is likely threaten the wholesomeness of food and consequently to...
A molecular direct approach have been used to study microbial ecology of spore-forming clostridia present in Grana Padano cheese with late blowing defect. The purpose of this work was to identify the dominant bacteria responsible of this food damage and after this, to determine the average amount of their spoiling cells and spores. A Clostridium-specific denaturing gradient gel electrophoresis (DGGE) performed on total DNA extraction from cheeses, was set to monitor clostridia communities and...
The effect of organic salt, tetrabutylammonium hexafluorophosphate doping on the performance of single layer bulk heterojunction organic solar cell with ITO/MEHPPV:PCBM/Al structure was investigated where indium tin oxide (ITO) was used as anode, poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEHPPV) as donor, (6,6)-phenyl-C61 butyric acid methyl ester (PCBM) as acceptor and aluminium (Al) as cathode. In contrast to the undoped device, the electric field-treated device doped with...
History of swelling over face or feet or abdomen indicates Hypoproteinemia causing loss of …… force in plasma and resulting edema. The pleural effusion is a part of this systemic edema. Acute onset of fever, chest pain, cough and breathlessness suggests infection involvement of pleura. This infection can be bacterial, usually with accompanying pneumonia and the clinical picture is usually 'hot'. Similar sub acute presentation may be seen in tubercular pleurisy with effusion in which the...
Tamer Baykara et. al., (2002) 20 developed Microsponges containing ketoprofen and Eudragit RS 100 by employing quasi-emulsion solvent diffusion method. The effects of different mixing speeds, drug/polymer ratios, solvent/polymer ratios on the physical characteristics of the Microsponges as well as the in vitro drug release rate from the Microsponges were investigated. In vitro dissolution results showed that the release rate of ketoprofen was modified in all formulations. D'souza J. I et. al.,...
The atomic bombings of Hiroshima and Nagasaki have yielded an increased risk of genetic diseases among survivors and their offspring. Based on factors including the amount of radiation received, age at the time of the bombings, shielding and degree of differentiation of exposed tissues, this review will discuss findings of the past 65 years with regard to effects such as solid cancers, liquid cancers, birth defects, physical growth and development and mental development of survivors. Most of...
To acquire these characteristics in resins based composites nano sized fillers were developed. Nano-hybrid resin based composites contain a hybrid mixture of colloidal silica particles of 20 to 60 nm and other inorganic fillers in the size range of 0.1-2.5μm, such as borosilicate in conventional methacrylate based resin matrix [107]. Summita et al. compared the properties of cosmetic dental nano-composite, Filtek Supreme Universal Restorative (3M ESPE Dental Products, St. Paul, Minn) with...
