We have developed a novel metal tag, bis(ethylenediamine)-4'-methyl-4-carboxybipyridine-ruthenium N-succinimidyl ester (ECRS) for sensitive analysis of amino acids using high performance liquid chromatography/inductively coupled plasma mass spectrometry (HPLC/ICP-MS). ECRS is a functional reagent, containing an ester group at one end that can be activated to bind to amino group and a chelated r...

Tumor cells obtained from leukemia and lymphoma patients were investigated for specific insulin receptors. Using radioactive 125I-labeled insulin, specific insulin binding sites were demonstrated on most acute lymphocytic leukemia (ALL) and acute myelocytic leukemia (AML) cells, including acute promyelocytic leukemia (APL), chronic myelocytic leukemia (CML), and acute monocytic leukemia (AMoL) ...

A Synechococcus sp. PCC 7942 bioreporter strain capable of sensing bioavailable Fe was constructed by fusing the Fe-responsive isiAB promoter to the Vibrio harveyi luxAB genes. Monitoring luxAB-dependent luminescence through the growth curve demonstrated that in Fe-replete media, transcription from the isiAB promoter was induced transiently in the mid-exponential phase of growth. The initiation...

Jagos P., V. Dvorak, J. Bouda: Levels of Minerals in the Blood Plasma of Cows and their Calves fed from Buckets. Acta vet. Brno, 50, 1981: 33-41. The concentration in plasma of calcium, magnesium, inorganic phosphorus, zinc, copper and iron in 40 cows and their calves up to the age of three months was followed in winter season under conditions of large-scale technology. The statistically signif...

spiders are the powerful and efficient predators in almost all ecosystems which have effective role in different pest control. the fauna of these arthropods was surveyed during 2005-2009, and their population fluctuations and activities were studied in mazandaran paddy fields in 2005-2006. a total of 53 spider species of 44 genera were collected and identified from paddy fields of mazandaran pr...

Abstract We developed a nonlinear optical crystal-based compact terahertz (THz)-microfluidic chip with several I-design meta-atoms for attomole (amol)-level sensing of trace amounts solution samples. The meta-atom consists metallic strip micometer-sized gap sandwiched by other strips. It is periodically arrayed in row 1 × 5 units. A point THz source locally generated rectification at the irradi...

The continued spread of antimicrobial resistance is a global problem. In fact, the WHO has declared one top 10 public health threats facing humanity. Molecular methods offer faster means characterizing resistant strains than phenotypic drug susceptibility testing. We have developed molecular detection method that generates visible aggregates from DNA amplified products and functionalized magnet...

SUMMARY In order to survey goiter prevalence in mountainous villages of Arnot city (state of Mazandaran) I 76 boys and 157 girls were studied in Bayjan, Vana and Rineh. Goiter was present in 68 % , 71 % of girls and 65 % of boys. Dissemination of grades of goiter were: la 21.9%, lb 23.5%, II 18.6% and III 3. 6 % . There was an increase in the rate of large goiters with age. 50th percentile of...
