siilver tetrafluoroborate complex of 5.11.17.23-tetra-tert-butyl-25-26,27,28-tetrakis (diphenylphosphinoylmethoxy)calyx[4]arene (l) has been synthesized by reaction of silver tetrafluoroborate and l in dichloromethane at room temperature. the complex formed has a 1:1 metall/ligand ratio. 1h and 31p nmr data support an encapsulated structure of the complex in which silver ion is located inside t...

objective: antigen 85 complex of mycobacterium tuberculosis includes three immunogenic proteins which are important tb vaccine candidates. the use of these protein as a component of subunit vaccines, as a part of dna vaccines or recombinant bcg boosters, enhances their recombinant production. recombinant production of these mycobacterial proteins located in the cell wall somehow differs from th...

carney syndrome (cs) is an autosomal dominant multiple neoplasia syndrome that includes cardiac, endocrine, cutaneous, and neural tumors. cardiac myxomas can be seen in the course of cs. a 46-year-old female patient was admitted to our clinic with palpitation, cough, and exertional dyspnea. physical examination revealed pigmented lesions, especially scattered in the neck, chest, and extremities...

background: based on biochemical properties, enterobacter cloacae represents a large complex of at least 13 variant species, subspecies, and genotypes that progressively identified as the most species causing hospital-acquired infections. the aim of this study was to determine the relevance between phylogenetically related strains within the e. cloacae complex and the frequency of urinary tract...

background: culex pipiens complex shows variations in morphological and biological characters including differ­ent biological forms and has medical and veterinary importance. because of having morphological variations, some­times it is not easy to separate this species from cx. quinquefasciatus and cx. torrentium . the aim of this study was to   identify the   culex pipiens complex species in o...

conclusions among anatomic variations, septal deviation and concha bullosa are predisposing factors for chronic sinusitis and we recommend that patients with chronic sinusitis be treated by surgical procedures. background identifying predisposing factors for chronic sinusitis is very important. objectives anatomical variation of the lateral nasal wall has been investigated in several studies an...

Feasibility of using Cyanex 301, as the auxiliary agent, for supercritical extraction of Cupper and Manganese cations from solid matrix was studied statistically. The amount of extraction is influenced by several parameters, such as amount of ligand, pressure, temperature, SCCO2 flow rate, time of extraction and amount of acid. Recent researches showed that factorial design is an effective tool...

a large number of simple or complex translocation involving the cml and aml chromosomal abnormalities has been described. this study was aimed to investigate the complex chromosome aberrations in the series of myeloid malignancies including cml and aml. the present report deals analyzed 187 consecutive with cml and aml patients, using methotrexate  cell synchronization and  un-stimulated cultur...

The present study determined and compared contents of macro- (Nitrogen-N, Phosphorus-P, Potassium-K, Calcium-Ca, Magnesium-Mg) and micro- (Zinc-Zn, Iron-Fe, Manganese-Mn, Cupper-Cu) nutrients in four seagrass species big-leaved (BL) Halophila ovalis (R. Br.) Hook. f., small-leaved (SL) H. ovalis (R. Br.) Ascherson, H. spinulosa (R. Br.) Aschers. in Neumayer and Halodule uninervis (Forssk.) Asch...

haptoglobin (hp) is a mammalian serum glycoprotein showing a genetic polymorphism with three types, 1-1, 2-2 and 1-2. hp appears to conserve the recycling of heme-iron by forming an essentially irreversible but non-covalent complex with hemoglobin which is released into the plasma by erythrocyte lysis. as an important consequence, haptoglobin-hemoglobin complex (hp-hb) shows considerable antiox...
